Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 3, the invention comprises a cylinder body 1 with an upward opening, a vertical stirring shaft 2 is arranged in the cylinder body 1, a plurality of impellers 3 are sleeved on the stirring shaft 2, the rotation directions of the impeller 3 at the lowest part are opposite to that of other impellers 3, and a discharge pipe 4 is connected to the rear side surface of the upper end of the cylinder body 1; the bottom of the cylinder body 1 is connected with a plurality of feed pipes 5, and the feed pipes 5 are provided with one-way valves 6; the end part of each feeding pipe 5 is connected with a bin 7, the cross section of each bin 7 is different in size, an extrusion plate 8 capable of moving up and down is installed in each bin 7, a plurality of through holes 9 are formed in the extrusion plate 8, and a blocking piece 10 enabling fluid to pass through in a single direction is installed at the bottom of each through hole 9; each extrusion plate 8 is provided with a vertical guide rod 11;

each guide rod 11 is sleeved with a tension spring 13, the bottom of each guide rod 11 is connected with a rope 14, and the free end of each rope 14 is connected to the stirring shaft 2 backwards through guide wheels; the guide rod 11 can move up and down in a reciprocating way by the reciprocating rotation of the stirring shaft 2.

In order to realize the rotation of the impeller 3, the sleeve 12 is sleeved on the stirring shaft 2, the sleeve 12 and the stirring shaft 2 realize coaxial reversal through a bevel gear set, wherein the impeller 3 at the lowest part is sleeved on the sleeve 12, and the other impellers 3 are sleeved on the stirring shaft 2.

In order to realize the reciprocating rotation of the stirring shaft 2, the stirring shaft 2 is driven by a stepping motor to rotate.

In order to realize the installation of the separation blade 10, one end of the separation blade 10 is hinged, and meanwhile, a torsional spring is installed at a hinged point and enables the separation blade 10 to be in a state of blocking the through hole 9.

In order to better block the through hole 9, the upper end face of each baffle plate 10 is provided with a rubber gasket 15.

When the mixing device is used, different medicaments to be mixed are added into the plurality of bins 7, and the plurality of bins 7 are connected with the barrel body 1 through the feeding pipe 5 and the one-way valve 6, so that the plurality of different medicaments can enter the barrel body 1 together to be mixed.

Then, the stepping motor is started, and because the stepping motor is set to rotate in a reciprocating manner, and the stirring shaft 2 is matched with the sleeve 12 through the bevel gear set, the rotation directions of the impeller 3 arranged on the stirring shaft 2 and the impeller 3 arranged on the sleeve 12 are opposite, cross stirring can be carried out, so that the liquid medicine is stirred more fully, and meanwhile, because the stepping motor rotates in a reciprocating manner, each impeller 3 can also rotate in a reciprocating manner; meanwhile, because the rotating directions of the blades on each impeller are not communicated, when a plurality of impellers 3 are arranged, opposite turbulent flow is generated, so that the liquid medicine in the cylinder body 1 is fully mixed.

In the reciprocating rotation process of the stirring shaft 2, the stirring shaft 2 is uniformly distributed and fixed on the rope 14 at the end part of each guide rod 11, so that after the stirring shaft 2 rotates, the rope 14 is wound on the stirring shaft 2, the length of the rope 14 is reduced, and the guide rods 11 move downwards; when the guide rod 11 moves downwards, the extrusion plate 8 is driven to move downwards, and the extrusion plate 8 is hinged with a blocking piece 10 positioned below each through hole 9, so that when the extrusion plate 8 moves downwards, the blocking pieces 10 block the through holes 9, and a rubber gasket 15 on the upper end surface of the blocking pieces 10 seals the through holes 9, so that the medicament positioned below the extrusion plate 8 is extruded and enters the bottom of the barrel body 1 through the feed pipe 5; and mixing is performed in the cylinder 1.

Because the cross section areas of the bins 7 are different in size, and the descending height of the guide rod 11 is consistent with the descending height of the extrusion plate 8 when each rotating shaft rotates in a reciprocating manner, the size of the cross section of each bin 7 directly determines the amount of the medicaments input into the barrel body 1 by each bin 7, and therefore the bins 7 with different cross section areas can be used for mixing a plurality of medicaments according to different proportions; can be suitable for different process production requirements.

Because the overflow pipe of a take the altitude is seted up to the upper end of barrel 1, discharging pipe 4 promptly, therefore multiple medicament enters into barrel 1 after the below of barrel 1, through the stirring, can mix gradually together to make the liquid level of the inside of barrel 1 rise, and rise to surpass discharging pipe 4 after, the mixed liquid can flow in and flow out through discharging pipe 4, thereby realized continuous entering and discharge.

In the production process, the medicine in the bin 7 can be supplemented anytime and anywhere, and a proper modulator can be added according to the report of subsequent detection, so that the whole process does not need to be stopped, and the convenience of operation is greatly improved.

In this device, install one-way wobbling separation blade 10 in the through-hole below of stripper plate 8, realized that stripper plate 8 reciprocates the back, can be with the below of the stripper plate 8 of the medicine flow of stripper plate 8 top, and through the extrusion, make the medicine enter into in barrel 1, carry out abundant stirring in barrel 1, because install check valve 6 on the inlet pipe 5, consequently, mutually supporting of baffle 10 and check valve 6 can make the medicine only can't advance and stir, and the overflow.

This device is in the barrel 1 at center through the setting to at a plurality of feed bins 7 of the peripheral installation of barrel 1, through motor drive, realized abundant diversified stirring on the one hand, on the other hand has realized the extrusion of stripper plate 8 in the feed bin 7, makes the material can enter into the inside of feed bin 7, and finally discharges through discharging pipe 4, thereby has realized the mixture of serialization, has improved the effect and the efficiency of mixing.

Because the plurality of bins 7 are all in an open state, the device can supplement the raw material liquid at any time and any place, thereby ensuring the continuity of production, and a liquid level sensor can be arranged in the bins 7 for reminding or controlling according to actual requirements; meanwhile, if the subsequently detected pH value or viscosity of the product does not meet the standard, the modulating agent can be added into the stock bin 7 in time, so that the adjustment without stopping is realized.

This device only needs a motor, alright in order to accomplish processes such as feeding, ejection of compact, stirring, can also adjust the proportion of feeding simultaneously through the size that sets up the feed bin, and is simple high-efficient, saves the cost, saves electric power.
