Also, the terms "connected" and "coupled" when used herein, unless otherwise indicated, encompass both direct and indirect connections (couplings). The term "plurality" means not less than two.

In the description of the present specification and claims, the terms "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred device or unit must have a specific direction, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Embodiments of the present application will now be described with reference to the accompanying drawings.

The first embodiment is as follows:

fig. 1 to 6 show a particular embodiment of a tank of the type of the present application for storing liquids, in particular water, comprising a tank body, a tank cavity 4 and a tank mouth as is also the case with conventional water tanks. The difference is that the tank is a vacuum tank, and the tank body is of a vacuum heat-preservation structure. Specifically, the tank body includes: the vacuum heat insulation device comprises an outer shell 1, an inner shell 2 arranged in the outer shell, and a vacuum heat insulation cavity 3 formed between the outer shell and the inner shell. The aforementioned tank cavity 4 is formed inside the inner shell 2. The outer shell 1 and the inner shell 2 are both made of stainless steel.

If with traditional scheme, hang inner shell 2 of vacuum tank in outer shell 1 in midair, when the tank cavity volume is great, when storing tens tons even hundreds of tons of water, under the water action of gravity, inner shell 2 falls the deformation easily, pastes with outer shell 1 large tracts of land and contacts for heat passes fast between inner shell and outer shell, reduces the heat insulating ability of jar. And, the falling deformation of the inner case 2 is likely to cause the sealing of the vacuum insulation chamber to be broken to leak air, thereby losing the vacuum insulation capability.

In view of this, the vacuum tank of the present embodiment is modified as follows: the outer shell 1 and the inner shell 2 are fixedly connected at the bottom and the top of the vacuum tank. On one hand, the top of the outer shell 1 provides an upward lifting force for the inner shell 2 filled with water; on the other hand, the bottom of the housing 1 also provides an upward supporting force to the inner housing 2. Even if the inner case 2 stores hundreds of tons of water, there is no fear of the problem of the inner case 2 falling and deforming.

However, when the inner shell 2 is fixedly connected to both the top and the top of the outer shell 1, and the inner shell 2 has a large size and a volume of several tens or even several hundreds of cubes, such a problem will be very prominent: in practice, the inner shell 2, which is in direct contact with the hot (or cold) water in the tank cavity, is at a higher (or lower) temperature. When hot water is stored in the tank, the outer shell 1, which is located at the periphery of the inner shell 2 and is separated by the vacuum insulation chamber 3, does not sense the temperature of the hot water inside, and the temperature of the outer shell 1 is very significantly lower than that of the inner shell 2 and is close to the ambient temperature. When the temperature of the hot water in the tank cavity is reduced greatly or the cold water is stored in the tank cavity, the temperature of the inner shell 2 is obviously lower, and the temperature of the outer shell 1 is not influenced by the temperature of the internal water and is changed obviously. The temperature variation range of the inner shell 2 can even reach hundreds of degrees celsius. The size of the inner casing 2 at high and low temperatures is significantly different according to expansion and contraction. The outer shell, which is located at the periphery of the inner shell, is not affected by the temperature of water, and the temperature of the outer shell is basically maintained within a small range. The large size deformation of the inner shell, especially the deformation of the height size thereof, can cause the inner shell and the outer shell to generate very large interaction force at the joint of the two, the interaction force causes the deformation of the vacuum tank, and the deformation can cause the air leakage of the vacuum heat insulation cavity 3 and the loss of the heat insulation capability.

There is also a case: the temperature of the water stored in the tank cavity is kept at a fixed value throughout the year, and the variation range of the environmental temperature can reach dozens of degrees centigrade in one year. The size of the inner shell can not be obviously changed, but the size of the outer shell 1 can be obviously changed in different periods, so that the vacuum tank is deformed, the vacuum heat insulation cavity 3 leaks air, and the heat insulation capacity is lost.

For the reasons mentioned above, the present application integrally provides a ring-shaped deformed corrugation 2a around the periphery of the tank cavity 4 on the wall of the inner shell 2 of the vacuum tank. The deformed pleats 2a are part of the wall of the inner shell 2.

When the temperature of the inner shell 2 rises, the deformation wrinkles 2a on the shell wall of the inner shell shrink to absorb the expansion deformation of the inner shell, so that the expansion stress of the inner shell is prevented from concentrating on the connection part of the inner shell and the outer shell to cause the deformation of a vacuum tank and even the air leakage of a vacuum heat insulation cavity. When the temperature of the inner shell 2 is reduced, the deformation wrinkles 2a on the shell wall of the inner shell stretch to compensate the shrinkage deformation of the inner shell, and the phenomenon that the shrinkage stress of the inner shell is concentrated at the joint of the inner shell and the outer shell to cause the deformation of a vacuum tank or even the air leakage of a vacuum heat insulation cavity is also avoided.

When the temperature of the outer shell increases and the size, particularly the height, of the outer shell increases, the inner shell 2 having the deformed wrinkles 2a can be easily increased along with the outer shell 1. When the temperature of the outer shell is reduced and the size, particularly the height, of the outer shell is reduced, the inner shell 2 with the deformed wrinkles 2a can be very easily reduced along with the outer shell 1. The vacuum tank is prevented from being deformed or even the vacuum heat insulation cavity is prevented from being leaked due to the fact that extension or contraction stress of the outer shell is concentrated on the connection position of the inner shell and the outer shell.

When the height of the vacuum tank is large, such as ten meters or even tens of meters, it is difficult to completely absorb/release the expansion and contraction deformation of the inner shell by only providing one deformation fold 2a on the inner shell 2, so the present embodiment provides a plurality of deformation folds 2a on the shell wall of the inner shell 2, and the deformation folds 2a are arranged at equal intervals along the height direction of the inner shell 2.

In this embodiment, the inner shell 2 is a solid of revolution with its axis extending vertically, and the deformed wrinkles 2a are in a ring structure arranged coaxially with the inner shell 2.

Further, the deformed fold 2a is a circle of radially outward-protruding extrusion ring rib, and an extrusion ring groove is formed on the inner periphery of the extrusion ring rib. It is understood that the annular extrusion ring rib integrally processed on the wall of the inner shell 2 is of a bent structure, and compared with the smooth main body part of the metal inner shell 2, the extrusion ring rib of the bent structure has better axial extension/contraction deformation capability.

Obviously, the deformed fold 2a is a radially inwardly protruding pressed bead.

As mentioned above, in order to improve the water storage capacity of the vacuum tank and prevent the vacuum tank from deforming even leaking air and losing temperature after storing a large amount of water, the outer shell 1 and the inner shell 2 are fixedly connected at the bottom and the top of the vacuum tank. Further, the vacuum tank is provided with two tank openings which are respectively arranged at the top connection part and the bottom connection part of the inner shell and the outer shell, and the two tank openings are as follows:

the outer shell 1 and the inner shell 2 are fixedly connected at the bottom of the vacuum tank through a support ring 5, and a tank opening, namely a lower tank opening 6, arranged at the bottom of the vacuum tank vertically penetrates through the outer shell 1, the inner shell 2 and the support ring 5. The outer shell 1 and the inner shell 2 are fixedly connected with the top of the vacuum tank through a ring sleeve 7, and an upper tank opening 8 which is a tank opening arranged on the top of the vacuum tank vertically penetrates through the outer shell 1, the inner shell 2 and the ring sleeve 7.

In this embodiment, the support ring 5 is welded to the inner shell 2 and the outer shell 1, respectively, and the collar 7 is also welded to the inner shell 2 and the outer shell 1, respectively. In order to improve the tightness of the inner and outer shells at the junction between the lower counter-hoop 5 and the upper hoop 7, an adhesive may be provided at the junction. Of course, if the adhesive strength of the adhesive is high enough, the support ring 5 can be directly adhered and fixed to the inner casing 2 and the outer casing 1, and the ring sleeve 7 can be directly adhered and fixed to the inner casing 2 and the outer casing 1.

In order to facilitate the welding of the ring sleeve 7 with the inner shell and the outer shell and improve the welding strength, flanging holes which are flanged upwards are respectively formed at the tops of the outer shell 1 and the inner shell 2, and the ring sleeve 7 is attached to and sleeved in the flanging holes and is welded and fixed with the flanging holes.

As can be seen from the above, in the present embodiment, the support ring 5 and the collar ring 7 are both third members that are separate from and connected to the inner casing 2 and the outer casing 1. In addition to this, we can also use this form of the counter-hoop 5 and loop 7:

the support ring 5 comprises an upper ring body integrally formed on the inner shell 2 and a lower ring body integrally formed on the outer shell 1, and the upper ring body and the lower ring body are welded and fixed. That is, a part of the support ring 5 is integrated with the inner shell 2, and the other part is integrated with the outer shell 1, and the two parts are welded to each other to form the support ring 5. Further, the upper ring may be a downward burring hole integrally formed on the inner case 2, and the lower ring may be an upward burring hole integrally formed on the outer case 1. The upper ring sleeve 7 comprises an upper ring body integrally formed on the inner shell 2 and a lower ring body integrally formed on the outer shell 1, and the upper ring body and the lower ring body of the ring sleeve are welded and fixed. That is, one part of the ring sleeve 7 is integrated with the inner shell 2, the other part is integrated with the outer shell 1, and the two parts are welded with each other to form the ring sleeve 7.

In addition, when the size of the outer shell 1 of the vacuum tank is large, the outer shell 1 is very easy to inwards deform in a concave mode under the action of external force (the inner side of the outer shell is a negative pressure environment), and then the outer shell 1 is attached to the inner shell 2 in a large area to be contacted, so that heat is rapidly transferred between the inner shell and the outer shell, and the heat insulation performance of the tank is reduced. Although the increase in the thickness of the outer shell 1 can solve the above problems well, it brings with it various problems such as a large amount of materials, high manufacturing cost, heavy and difficult movement of the can body, and the like. In addition, when a large-sized housing is manufactured, if the housing is subjected to heat treatment to improve the structural strength, the roundness of the housing is inevitably deteriorated, and the pressure-bearing capacity of the finally molded housing 1 is weakened.

In view of this, the present embodiment abandons the solution of increasing the thickness of the shell 1, and arranges a support ring 11 supported on the inner circumference of the shell 1 in the vacuum insulation chamber 3 to support the shell when the shell 1 is radially recessed, so as to improve the deformation resistance of the shell.

In order to facilitate the manufacture and installation of the shell 1 and the supporting ring 11 and ensure that the pressure born by each part of the shell 1 and the supporting ring 11 is as uniform and consistent as possible, the shell 1 adopts a revolving body structure similar to a cylinder, and the supporting ring 8 adopts a circular ring structure coaxially arranged with the revolving body.

If only one support ring 11 is provided, the housing portion far from the support ring 11 still has a problem of poor pressure-bearing capability. Based on this, in the present embodiment, a plurality of supporting rings 11 are collectively provided on the inner periphery of the housing 1, and these supporting rings 11 are arranged next to each other in the height direction of the housing 1 from the inner bottom of the housing to the inner top of the housing. The supporting rings 11 arranged next to each other are wrapped and positioned by the shell 1, the outer shell 1 mainly plays a role of sealing and positioning the supporting rings, and the inner supporting ring 11 is a main bearing part, so that the shell 1 can be made to be thin and is convenient to machine and form.

The support ring 11 is a circular ring made of high-strength steel and has extremely strong pressure-bearing and deformation-resistant capabilities.

The brace ring 11 is integrally provided with a brace ring rib 11a located on the inner periphery of the brace ring and coaxially arranged with the brace ring, as shown in fig. 2 and 5. The bracing ring 8 with the bracing ring reinforcing ribs 11a on the inner periphery has higher pressure bearing capacity. In this embodiment, the hoop reinforcement 11a is an extrusion protrusion formed by extruding the hoop 11.

When the temperature of the inner shell 2 is high or the pressure inside the inner shell is high, radial deformation expanding outwards is generated, and the periphery of the inner shell 2 is a low-pressure vacuum environment. If the expansion deformation is too large, the inner shell 2 is attached to the outer shell 1 in a large area, so that heat is rapidly transferred between the inner shell and the outer shell, and the heat insulation performance of the vacuum tank is reduced. Furthermore, if the inner shell 2 is subjected to high internal pressures for a long period of time, there is a risk that the inner shell 2 will break due to fatigue deformation.

For this reason, in the present embodiment, the hoop 12 located in the vacuum heat insulation cavity 3 is fixedly sleeved on the periphery of the inner shell 2, so as to hoop the inner shell when the inner shell 2 expands radially outward, thereby improving the pressure resistance of the inner shell 2 and reducing the outward expansion deformation of the inner shell 2.

As mentioned above, the inner shell 2 is a solid of revolution with its axis extending vertically, so that the pressure of each part of its inner wall is basically uniform and the deformation resistance is good. In order to make the outward expansion pressure of each part of the hoop 12 uniform and to improve the deformation resistance of the inner shell, the hoop 12 is a circular ring structure arranged coaxially with the inner shell 2.

If only one hoop 12 is arranged, the part of the inner shell 2 far away from the hoop 12 still has the problems of poor pressure bearing capacity and easy fatigue deformation. In view of this, in the present embodiment, a plurality of hoops 4 are sleeved on the outer periphery of the inner shell 12, and the hoops 4 are uniformly arranged along the height direction of the inner shell 2 at intervals.

The hoop 12 is also made of high-strength steel and has a very strong pressure-resistant and deformation-resistant ability. During manufacturing, the hoop 12 and the supporting ring 11 made of high-strength steel can be subjected to heat treatment to improve the structural strength of the hoop 12 and the supporting ring 11.

The hoop 12 is integrally provided with hoop reinforcing ribs 12a located on the outer periphery of the hoop and arranged coaxially with the hoop, as shown in fig. 2 and 6. The hoop 12 having the hoop reinforcement ribs 12a on the outer periphery has a greater strength. In this embodiment, the hoop reinforcement ribs 12a are extrusion protrusions formed by extrusion processing of the hoop 12.

To prevent the hoop 12 from being detached from the inner shell 2, the hoop 12 may be adhesively fixed to the inner shell 2.

Example two:

figures 7 to 10 show a second particular embodiment of a tank of the type of the present application, which is structurally similar to the tank of the first embodiment, with the main differences that: in the present embodiment, the wall of the inner casing 2 is not provided with deformation wrinkles for absorbing/releasing deformation, but the wall of the outer casing 1 is integrally provided with annular deformation wrinkles around the periphery of the inner casing 2. For the purpose of explaining the technical solution, the deformed folds in the housing 1 will now be referred to as housing deformed folds 1 a.

When the temperature of the outer shell 1 rises, the outer shell deformation wrinkles 1a on the shell walls of the outer shell shrink to absorb the expansion deformation of the outer shell, so that the expansion stress of the outer shell is prevented from being concentrated at the joint of the inner shell and the outer shell to cause the deformation of the vacuum tank and even the air leakage of the vacuum insulation cavity. When the temperature of the outer shell 1 is reduced, the outer shell deformation wrinkles 1a on the wall of the outer shell stretch to compensate the contraction deformation of the outer shell, and the phenomenon that the contraction stress of the outer shell is concentrated at the joint of the inner shell and the outer shell to cause the deformation of the vacuum tank or even the air leakage of the vacuum heat insulation cavity is also avoided.

When the temperature of the inner casing rises and its size, particularly its height, increases, the outer casing 1 with the outer casing deformation folds 1a can very easily follow the inner casing 2 to increase. When the temperature of the inner shell is reduced and the size, particularly the height, of the inner shell is reduced, the outer shell 1 with the outer shell deformation wrinkles 1a can be very easily reduced along with the inner shell 2. The vacuum tank is prevented from being deformed or even the vacuum heat insulation cavity is prevented from being leaked due to the fact that extension or contraction stress of the outer shell is concentrated on the connection position of the inner shell and the outer shell.

If the height of the vacuum tank is large, it is difficult to completely absorb/release the expansion deformation of the inner shell by only providing one outer shell deformation fold 1a on the outer shell 1, so the present embodiment provides a plurality of outer shell deformation folds 1a on the wall of the outer shell 1, and the outer shell deformation folds 1a are arranged at equal intervals along the height direction of the outer shell 1.

The housing 1 is a substantially cylindrical solid of revolution with its axis extending vertically, and the deformed wrinkles 2a are in the form of a ring structure arranged coaxially with the housing 1.

The structure of the outer shell deformation fold 1a is the same as that of the inner shell deformation fold of the first embodiment, and the outer shell deformation fold is also a circle of radially outward-protruding extrusion ring rib, and an extrusion ring groove is formed in the inner periphery of the extrusion ring rib. Of course, the deformation corrugation of the shell can also adopt a radial inward convex extrusion ring rib.

In this embodiment, a hoop 12 is also disposed in the vacuum insulation chamber 3, which is hooped around the outer periphery of the inner shell 2, but a support ring for supporting the outer shell 1 is not provided. This is because the outer shell of extrusion ring muscle structure warp fold 1a itself just has fine radial bearing strength, even if do not set up the support ring in outer shell 1, singly utilize extrusion ring muscle to support outer shell 1, also can effectively prevent that the outer shell from collapsing inwards under vacuum suction or external force and warping and leaning on with the inner shell and leading heat.

The outer shell 1 and the inner shell 2 are fixedly connected at the bottom of the vacuum tank through a support ring 5, and a lower tank opening 6 which is a tank opening arranged at the bottom of the vacuum tank vertically penetrates through the outer shell 1, the inner shell 2 and the support ring 5. The outer shell 1 and the inner shell 2 are fixedly connected with the top of the vacuum tank through a ring sleeve 7, and an upper tank opening 8 which is a tank opening arranged on the top of the vacuum tank vertically penetrates through the outer shell 1, the inner shell 2 and the ring sleeve 7.

Likewise, the counter-hoop 5 and the loop 7 may also adopt such a structure: one part of the support ring 5 is integrated with the inner shell 2, the other part is integrated with the outer shell 1, and the two parts are welded with each other to form the support ring 5. One part of the ring sleeve 7 is integrated with the inner shell 2, the other part is integrated with the outer shell 1, and the two parts are welded with each other to form the ring sleeve 7.

Example three:

figures 11 to 14 show a third particular embodiment of a tank of the type of the present application, which is similar in structure to the tanks of the first and second embodiments, with the main difference that: not only the shell wall of the inner shell 2 is integrally provided with an annular deformation fold 2a surrounding the periphery of the tank cavity 4, but also the shell wall of the outer shell 1 is integrally provided with an annular outer shell deformation fold 1a surrounding the periphery of the inner shell 1. I.e. both the wall of the inner shell 2 and the wall of the outer shell 1 are provided with deformation corrugations.

The vacuum tank of the present embodiment is well suited for use in situations where: the two ends of the vacuum tank are fixed, and the heights of the inner shell and the outer shell of the vacuum tank are limited and fixed. Such as a vacuum tank, is fastened at both ends to an external support frame.

Example four:

fig. 15 to 18 show a fourth specific embodiment of the canister of the present application, which has a structure similar to that of the embodiment, and mainly differs from the structure of the opening of the canister and the fixed connection manner of the inner and outer shells at the opening, as follows:

the bottom of the outer shell 1 is integrally formed with an outer tube 101 extending downward, and the bottom of the inner shell 2 is integrally formed with an inner tube 201 extending downward and located inside the outer tube 101. The protruding ends of the inner pipe 201 and the outer pipe 101 are welded with a sealing plate 9, a part of the vacuum heat insulation cavity 3 is positioned between the inner pipe 201 and the outer pipe 101, and the sealing plate 9 is provided with a liquid feeding hole 9a communicated with the tank cavity 4. The liquid feed holes 9a of the closing plate 9 correspond to the lower port of the vacuum tank.

The top of the outer casing 1 is integrally formed with an outer pipe 101 extending upward, and the top of the inner casing 2 is integrally formed with an inner pipe 201 extending upward and located inside the top outer pipe 101. A sealing plate 9 is also welded at the extending ends of the top inner pipe 201 and the top outer pipe 101, a part of the vacuum heat insulation cavity 3 is positioned between the top inner pipe 201 and the top outer pipe 101, and a liquid feeding hole 9a communicated with the tank cavity 4 is also formed on the sealing plate 9 at the top. The liquid feeding holes 9a of the top closing plate 9 correspond to the upper tank opening of the vacuum tank.

In this embodiment, the two sealing plates 9 are both flange plates. Because the upper tank opening and the lower tank opening of the vacuum tank are both provided with flange structures, when the vacuum tank is actually used, the external connecting pipe 13 with the other flange plate at the end part can be very conveniently fastened and connected with the flange type sealing plate 9 at the tank opening position of the vacuum tank by the bolt 14 and the nut 15, so that the external connecting pipe 13 is communicated with the liquid guide pipe 10, and the connection part is sealed and is not easy to lose temperature, as shown in fig. 19.

In addition, in this embodiment, a liquid guide tube 10 is welded on the sealing plate 9 at the top of the vacuum tank, and the liquid guide tube 10 passes through the top inner tube 201 downward and extends into the tank cavity, and the liquid guide tube 10 is the same as the liquid feeding hole 9a on the sealing plate, so that in some application scenarios, a user can conveniently draw out the water stored in the tank from the upper tank opening of the vacuum tank by means of the liquid guide tube 10.

The extension tube 13 in fig. 19 is a vacuum tube.

Example five:

because in some cases the water temperature (or other liquid temperature) is not uniform throughout the tank, the water temperature in the upper layer is usually greater than the water temperature in the lower layer, for example: the water in the tank is heated by means of a heating device while normal-temperature water is supplied into the tank from the bottom extension pipe 13. Sometimes, it is desirable to draw the high temperature water up the tank; at other times, it is desirable to draw the low temperature water up the tank.

On this basis, fig. 20 to 23 show a fifth tank, which is also a vacuum tank structure, wherein a sealing plate 9 on the top of the tank is provided with two liquid feeding holes 9a, and two liquid guide pipes 10 with different lengths are welded on the sealing plate 9 on the top of the vacuum tank, the two liquid guide pipes 10 penetrate through the inner pipe 201 from the flange 9 downwards and extend into the tank cavity, and the two liquid guide pipes 10 are respectively arranged at the positions of the two liquid feeding holes 9a and are respectively communicated with the two liquid feeding holes 9 a. The short catheter tube 10 extends only to the top section of the tank cavity and the long catheter tube 10 extends all the way to the bottom section of the tank cavity. When the tank is used for temporarily storing and heating water stored in the tank, the long liquid guide pipe can be used as a water inlet pipe for supplementing normal-temperature water, and the short liquid guide pipe is used as a water outlet pipe for leading out high-temperature water. Of course, both the long liquid guide pipe and the short liquid guide pipe can be used as water outlet pipes, the long liquid guide pipe is used for leading out water with higher temperature, and the short liquid guide pipe is used for leading out water with lower temperature.

The aforementioned "top section of the tank cavity" and "bottom section of the tank cavity" have the meaning: if the height h of the tank cavity is equally divided into three parts, the height h/3 above the tank cavity belongs to the top section of the tank cavity, and the height h/3 below the tank cavity belongs to the bottom section of the tank cavity. The rest h/3 of the height belongs to the middle section of the tank cavity.

In this embodiment, the sealing plate 9 is not a flange plate structure, and the vacuum tank is not connected to the external pipe by two flange plates fastened to each other as in the fourth embodiment. Instead, the following steps are carried out: two liquid feeding holes 9a on the sealing plate 9 are threaded holes, and internal threads are formed on the hole walls of the liquid feeding holes 9a, so that when the vacuum tank is used, an external connecting pipe 13 with threads at the end part can be screwed into the threaded liquid feeding holes 9a, and the connection between the external connecting pipe 13 and the vacuum tank is realized.

Furthermore, it is also possible to connect the canister and extension tube 13 quickly in the manner shown in fig. 24, in which fig. 24 the upper bore section of the fluid feed bore 9a projects upwardly above the upper surface of the closure plate 9 and the projecting portion thereof is externally threaded. When the vacuum tank is used, the external connecting pipe 13 with the screw sleeve at the end part can be quickly locked and butted with the external thread section of the liquid feeding hole, so that the connection of the external connecting pipe 13 and the vacuum tank is realized.

In addition, in this embodiment, a mounting hole 9b is formed on the sealing plate 9, and an evacuation valve 16 is installed at the mounting hole 9b so as to draw water to the outside of the tank in a non-water-replenishing state or replenish water to the inside of the tank in a non-water-discharging state.

Example six:

fig. 26 to 29 show a sixth particular embodiment of the tank of the present application, which is structurally similar to the fifth embodiment, with the main differences:

the closing plate 9 is composed of an upper plate body 901 and a lower plate body 902, and the upper plate body 901 and the lower plate body 902 are both flange plates, and the two are detachably fastened and connected through mutually matched bolts 14 and nuts 15. The lower plate 902 is welded and fixed with the inner shell (specifically, the inner tube part on the top of the inner shell) and the outer shell (specifically, the outer tube part on the top of the outer shell) of the tank, and the two long and short liquid guide tubes 10 are welded and fixed with the lower plate 902.

The upper liquid guiding hole 9a of the sealing plate 9 vertically penetrates through the upper plate body 901 and the lower plate body 902, and only the hole section of the upper liquid guiding hole 9a of the upper plate body 901 is provided with an internal thread. When the vacuum tank is used, the external connecting pipe 13 with threads at the end part can be screwed into the threaded liquid feeding hole 9a of the upper plate body 901, so that the connection between the external connecting pipe 13 and the vacuum tank is realized.

Similarly, the mounting hole 9b of the closing plate 9 also penetrates through the upper plate 901 and the lower plate 902, and only the hole section of the mounting hole 9b of the upper plate 901 is internally threaded. The evacuation valve 16 is screwed into the mounting hole 9b of the upper plate body 901.

Of course, we can also adopt the mode of quick connection between the tank and the external pipe 13 as shown in fig. 30, the liquid feeding hole 9a of the upper plate body 901 has a section of external thread extending upwards-the liquid feeding hole 9a protrudes upwards from the upper surface of the closing plate 9, and the protruding part is provided with external thread. When the vacuum tank is used, the external connecting pipe 13 with the screw sleeve at the end part can be quickly locked and butted with the external thread section of the liquid feeding hole, so that the connection of the external connecting pipe 13 and the vacuum tank is realized.

Compared with the fifth embodiment, the design has the advantages that: the upper plate body 901 is of a detachable structure, and when a connecting thread (an internal thread or an external thread) of the liquid guide hole is damaged, the upper plate body 901 can be replaced with a new one.

In order to avoid liquid leakage at the joint of the upper plate 901 and the lower plate 902, in this embodiment, the sealing rings 17 clamped between the upper plate and the lower plate are disposed on the peripheries of the mounting hole 9b and the two liquid feeding holes 9a of the lower plate 902.

To facilitate the positioning of the sealing ring 17, a ring groove is provided on the top surface of the lower plate 902 around the periphery of the dispensing hole 9 a. After assembly, the sealing ring 17 is embedded in the annular groove and clamped between the upper plate body and the lower plate body.

It can be seen that the main function of the lower plate body 902 is to attach the catheter 10, as well as to attach the removable upper plate body 902. The main function of the upper plate 902 is to facilitate connection with the external connection pipe 13, and when the threaded hole therein is damaged, the connection can be replaced quickly.

Example seven:

fig. 32 to 35 show a seventh embodiment of the canister of the present application, which is similar in structure to the sixth embodiment, with the main difference that:

two liquid guide holes 9a are arranged on the sealing plate 9, and the lower hole sections on the lower plate body 902 are the same hole section. In the sixth embodiment, the two liquid guiding hole segments on the lower plate 902 are combined into one large-diameter hole segment, but the sealing plate 9 still has two liquid guiding holes 9a as a whole. The two long and short liquid guide tubes 10 (the upper ends thereof) extend into the lower hole section of the liquid guide hole in the lower plate body 901 and are welded and fixed with the upper plate body 901.

It can be seen that the main purpose of the lower plate 902 is to facilitate the removable of the upper plate 902. The upper plate 902 serves to connect the catheter 10 and to facilitate connection to the extension tube 13. When the threaded hole in the catheter 10 or the upper plate body is damaged, the catheter can be replaced quickly.

Example eight:

fig. 36 to 39 show an eighth embodiment of the canister of the present application, which is similar in structure to the seventh embodiment, with the main difference that:

the cover plate 9 further includes an intermediate plate 903 sandwiched between the upper plate 901 and the lower plate 902, and the intermediate plate 903 is also a flange plate.

The two long and short liquid guide tubes 10 (the upper ends thereof) extend into the lower hole section of the liquid guide hole in the lower plate body 901 and are welded and fixed with the middle plate body 903.

The main function of the lower plate 902 is to facilitate the connection between the removable middle plate 903 and the upper plate 902. The main purpose of the middle plate 903 is to connect the catheter 10, which can be replaced quickly when the catheter 10 is damaged. The main effect of the upper plate body 902 lies in being convenient for connect external pipe 13, and the screw hole in the upper plate body can be replaced with new one quickly after being damaged.

It should be noted that although the fifth to eighth embodiments shown in fig. 20 to 39 do not include the inner tube and the outer tube extending downward and the sealing plate fixed to the inner tube and the outer tube, it is obvious to those skilled in the art that the fourth embodiment can be easily implemented: in embodiments five to eight, the vacuum tank is provided with an inner tube, an outer tube and a closing plate structure at the bottom similar to the top of the vacuum tank.

The above are exemplary embodiments of the present application only, and are not intended to limit the scope of the present application, which is defined by the appended claims.
