As shown in fig. 1, the dispenser 10 of an embodiment includes a base 110, an inner shaft 120, a feed tube 130, a housing 140, a wear portion 150, and a seal assembly 160. The dispenser 10 is used in a filling machine, and the base 110 is adapted to be removably connected to the housing 140. The base 110 may be detachably connected to the housing 140 through bolts, and the base 110 may be connected to the housing 140 by other forms such as a buckle.
Referring to fig. 1 again, a first through hole is formed in the base 110, the inner shaft 120 is rotatably connected to an inner wall of the first through hole, and the base 110 rotates around a central axis of the inner shaft 120. It should be noted that, the base 110 is configured to be detachably connected to a rotating bracket of the filling machine, and the rotating bracket drives the base 110 to rotate around the inner shaft 120, so that the base 110 drives the housing 140 to rotate around the inner shaft 120 together.
In addition, the inner shaft 120 is provided with a second through hole, and the feeding pipe 130 is inserted into the second through hole, and the central axis of the second through hole and the central axis of the first through hole are located on the same straight line. The feedback lumen 131 is formed between the feeding tube 130 and the inner wall of the second through hole, that is, the space between the wall of the feeding tube 130 and the inner wall of the inner shaft 120 forms the feedback lumen 131.
In an embodiment, the dispenser 10 may further include an intermediate tube located between the feed tube 130 and the inner shaft 120, an outer wall of the intermediate tube abutting an inner wall of the second through bore. The feed tube 130, the intermediate tube and the inner shaft 120 are connected by a tube sleeve, and a backflow cavity is formed by the space between the outer wall of the feed tube 130 and the inner wall of the intermediate tube. An intermediate tube is provided between the feed tube 130 and the inner shaft 120 so that the inner tube such as the feed tube 130 is not affected when the inner shaft 120 is replaced.
The inner shaft 120 and the feed tube 130 may be detachably connected. Therefore, when the inner shaft 120 is damaged and needs to be maintained, the inner shaft 120 can be directly disassembled, and the pipelines such as the feeding pipe 130 are not affected, so that the disassembly and the assembly are convenient. When an intermediate tube is sleeved outside the feed tube 130, the inner shaft 120 may also be detachably connected to the intermediate tube.
The casing 140 is located at a side of the base 110 away from the inner shaft 120, and a third through hole 141 and a fourth through hole 142 are formed in the casing 140. The third through hole 141 is communicated with the feeding pipe 130, and central axes of the third through hole 141, the first through hole and the second through hole are positioned on the same straight line. The fourth through hole 142 is used for communicating the return chamber 131 with a return pipe of the filling machine. In addition, the housing 140 is detachably connected to the base 110, thereby facilitating maintenance.
Specifically, the housing 140 is detachably connected to the connecting pipe of the filling machine, and the third through hole 141 communicates the feeding pipe 130 and the connecting pipe, thereby delivering the material from the dispenser 10 into the filling barrel of the filling machine. In addition, the housing 140 is detachably connected to the return pipe of the filling machine, and the fourth through hole 142 communicates with the return chamber 131 and the return pipe, so that the material in the return pipe is fed into the dispenser 10. The housing 140 rotates with the base 110 about the central axis of the inner shaft 120, thus achieving continuous delivery of fluid between the rotating parts and the stationary tubing.
It should be noted that the device may further include a first pipe and a second pipe, where the first pipe is inserted into the third through hole 141, the second pipe is inserted into the fourth through hole 142, the first pipe is communicated with the feeding pipe, the second pipe is communicated with the backflow cavity, and the second pipe is connected with the backflow pipe. Thereby preventing corrosion of the case 140 by the material and increasing the service life of the case 140.
In addition, when the second pipe is inserted into the fourth through hole, the return pipe and the housing 140 may be connected by a clip connection, so as to facilitate installation.
The abrasion resistant portion 150 is disposed between the inner shaft 120 and the housing 140, and the abrasion resistant portion 150 is detachably connected to the inner shaft 120. And the wear-resistant portion 150 is provided with a fifth through hole 151, and the fifth through hole 151 is used for communicating the fourth through hole 142 with the reflow chamber 131, so as to form a reflow channel.
In addition, the wear portion 150 can be used to withstand the pressure and friction caused by rotational movement of the base 110 relative to the inner shaft 120. Thereby preventing the inner shaft 120 from being worn out and increasing the service life of the inner shaft 120.
Because the wear-resistant portion 150 is detachably connected with the inner shaft 120, when the base 110 rotates relative to the inner shaft 120 to cause damage to the wear-resistant portion 150, the wear-resistant portion 150 can be directly detached for replacement, thereby facilitating maintenance. The wear-resistant portion 150 may be detachably connected to the inner shaft 120 by a bolt or the like.
In order to achieve sealability, the seal assembly 160 includes a first seal portion 161, a second seal portion 162, and a third seal portion 163. The first sealing portion 161 is disposed between the wear portion 150 and the housing 140. The second sealing portion 162 is disposed between the wear portion 150 and the base 110. A third seal 163 is provided between the wear part 150 and the feed tube 130.
The reflux cavity of the distributor of the traditional filling machine is sealed in a rotary sealing mode, a rotary sealing ring groove is required to be cut on the hole wall of the shell, and the processing difficulty is high. The novel structure adopts the mode of matching the wear-resistant part 150 and the sealing component 160 to realize the sealing and the diversion of liquid or gas, and each part has simple configuration and low processing difficulty. In addition, when the wear-resisting portion 150 is worn, the wear-resisting portion 150 is detached for replacement, and the whole distributor 10 is not required to be detached, so that the maintenance is convenient, and the cost of maintenance manpower and material resources is further reduced.
The material used for the wear-resistant portion 150 may be polyurethane, polytetrafluoroethylene, synthetic resin, or the like. In addition, the shape and size of the wear part 150 may be selected according to the inner shaft 120.
As shown in fig. 2 and 3, in an embodiment, the wear-resistant portion 150 is a wear-resistant ring, and the fifth through hole 151 is a kidney-shaped hole for communicating the fourth through hole with the return chamber. The fifth through hole 151 is a kidney-shaped hole, so that the flow cross-sectional area is larger, the flow rate of the backflow liquid is increased, and the flow and the evacuation are quicker and smoother.
In this embodiment, the number of kidney-shaped holes is 4, and 4 kidney-shaped holes Kong Chengzhou are symmetrically distributed. The number of the fifth through holes 151 is at least 1, and the shape of the fifth through holes 151 may be a circular hole or the like. As the abrasion-resistant ring is simpler to process, the common lathe milling machine can process and manufacture, and the cost is lower.
In the present embodiment, the wear part 150 is fixed to the inner shaft 120 using a bolt, which is connected to the inner shaft 120 through a fifth through hole 151.
As can be seen in fig. 1, the first sealing portion 161 is provided between the wear part 150 and the housing 140. Since the housing 140 rotates relative to the wear part 150 on the inner shaft 120, the first sealing part 161 is relatively worn with high wear probability, and thus a component having high wear resistance and convenient installation is required. In one embodiment, the first sealing portion 161 is a planar sealing ring, and seals in an end-face planar manner.
Compared with a rotary sealing mode, the end face plane sealing mode is simpler and easier to install, low in coaxiality requirement, easier to machine structural shapes of parts, less in fine machining positions, good in sealing performance and high in wear resistance, and the plane sealing ring is sealed through plane extrusion.
In addition, if the seal ring adopted has a groove gap, the groove gap is recessed towards the wear-resistant part to form a nest, so that flowing liquid can accumulate in the grooves, bacteria can grow, products produced by filling are polluted, and the quality and the taste of the products are endangered. As shown in fig. 4, when the first sealing portion 161 is a planar sealing ring, since the contact surface is planar, the surface through which the liquid flows has no groove and gap, so that the liquid volume is effectively prevented from remaining or residues are effectively prevented from accumulating, thereby eliminating the generation source of bacteria and reducing the risk of damage to sanitation and safety.
Further, since the second sealing portion 162 is provided between the wear-resistant portion 150 and the base 110, the base 110 is rotated, and the wear-resistant portion 150 is in a stationary state, so that the second sealing portion 162 is required to have high wear resistance. In one embodiment, the second sealing portion 162 is a Y-shaped sealing ring. The Y-shaped sealing ring is also called as Y-shaped ring, the section of the Y-shaped sealing ring is Y-shaped, the service life is longer, the friction resistance is small, and the rotation resistance can be reduced.
In addition, since the Y-ring is a typical lip seal, the lip of which faces the wear part, the Y-ring can effectively block the overflowed liquid from flowing toward the position between the inner shaft 120 and the base 110 when the liquid overflows from the wear part 150.
During the rotational movement of the base 110, the wear part 150 and the feed tube 130 are relatively stationary, where a seal suitable for static sealing is used. In one embodiment, the third seal 163 is a star seal. The third sealing portion 163 is located between the wear portion 150 and the feed tube 130, and may be a star-shaped ring capable of sealing in both directions. The separation of the material channel and the backflow channel is realized through the star-shaped ring, the reliable and good sealing effect can be achieved, liquid in the backflow channel is prevented from entering the feeding channel, the material is polluted, the surface of the star-shaped ring, which is contacted with the feeding pipe and the wear-resistant part, is a flat surface, the accumulation of residual liquid can be prevented, and the material is more sanitary.
The material channel is a channel formed by the feeding pipe 130 and the housing 140 and used for conveying materials, and the materials are input into the connecting pipe from the feeding pipe 130 through the third through hole 141 of the housing 140 and then are input into the filling barrel through the connecting pipe, as indicated by the arrow B in fig. 1. The return channel is a channel formed by the return cavity 131 and the casing 140 and used for recycling materials, and the materials sequentially enter the return cavity 131 from the return pipe through the fourth through hole 142 of the casing 140 and the fifth through hole 151 of the wear-resisting part 150 and are then conveyed into the material recycling tank of the filling machine, as indicated by an arrow C in fig. 1.
The number of the first sealing portions 161, the second sealing portions 162, and the third sealing portions 163 may be adjusted as needed. In the present embodiment, the number of the first sealing parts 161 is two, the number of the second sealing parts 162 is one, and the number of the third sealing parts 163 is one.
In addition, in one embodiment, the dispenser 10 further includes a bearing 122, the bearing 122 being disposed between the inner shaft 120 and the base 110, the base 110 being rotatably movable about the inner shaft 120 by the bearing 122. It should be noted that the number of the bearings 122 may be one or more. In the present embodiment, the number of bearings 122 is two.
In one embodiment, bearing 122 is an angular contact ball bearing. When adopting the plane sealing washer to seal, the axiality requirement is lower, selects the angular contact ball bearing to realize required rotation, and installation, maintenance are more convenient.
The bearing 122 may be a deep groove ball bearing, a tapered roller bearing, or the like.
In one embodiment, the base 110 is provided with a sixth through hole 112, and the sixth through hole 112 is used for observing the liquid flowing through the wear part 150. That is, the circumference of the abrasion resistant portion 150 can be observed through the sixth through hole 112 to judge the sealing condition of the dispenser 10. When liquid overflows from the sixth through hole 112, it indicates that the sealing property of the dispenser 10 is poor and maintenance is required.
During maintenance, only the bolts connecting the casing 140 and the base 110 are unscrewed, the bolts connecting the base 110 and the rotating bracket are unscrewed, and the base is detached, so that the wear-resistant part 150 or each sealing part of the sealing assembly can be replaced.
In one embodiment, the dispenser 10 further includes a cleaning fluid delivery tube 170, the cleaning fluid delivery tube 170 being disposed through the delivery tube 130, the cleaning fluid delivery tube 170 being configured to provide cleaning fluid to the filling machine. When the machine is required to be sterilized and cleaned, cleaning liquid is conveyed to the liquid filling barrel through the cleaning liquid conveying pipe 170, the filling machine is cleaned and sterilized, and the cleaned liquid flows out through the backflow channel so as to meet the standard requirement of sanitation and safety.
Wherein the cleaning liquid delivery pipe 170 may include a first cleaning liquid delivery pipe and a second cleaning liquid delivery pipe. The first cleaning liquid conveying pipe is connected with the second cleaning liquid conveying pipe. Specifically, in one embodiment, an end of the first cleaning liquid conveying pipe, which is close to the second cleaning liquid conveying pipe, is provided with an internal thread, and an end of the second cleaning liquid conveying pipe, which is close to the first cleaning liquid conveying pipe, is provided with an external thread which is matched with the internal thread. The first cleaning liquid conveying pipe and the second cleaning liquid conveying pipe are connected together through threaded connection of the internal threads and the external threads. In addition, the position of the connection of the first cleaning liquid delivery pipe and the second cleaning liquid delivery pipe is on the same level as the position of the connection of the connecting pipe of the filling machine and the delivery pipe 130.
