Description

Technical Field

[0001] The present invention relates to the field of veterinary drug production, and particularly relates to a crushing and sieving device for veterinary drug production. Background Art

[0002] Veterinary drugs refer to substances (including medicated feed additives) used for preventing, treating, or diagnosing animal diseases or purposefully regulating the physiological functions of animals. During the production of veterinary drugs, raw materials usually need to be crushed and sieved.

[0003] Specifically, for a raw material crushing and sieving device for veterinary drug production with the patent number CN218250623U, the device has the following defects when in use. For example, it is very difficult to crush the materials only by the crushing blades rotating forward or backward, and at the same time, it is also very difficult to scrape up or scrape the materials at the bottom of the crushing box and the sieving chamber only by the scraper to prevent the filter screen holes from being blocked. Summary of the Invention

[0004] The purpose of the present invention is to provide a crushing and sieving device for veterinary drug production.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A crushing and sieving device for veterinary drug production includes a barrel body. The bottom of the barrel body is provided with a discharge pipe, and the top of the barrel body is provided with a feed pipe:

[0007] A filter barrel I and a filter barrel II are arranged in parallel up and down in the barrel body. The filter barrel I is located directly above the opening of the filter barrel II. The filter barrel I and the filter barrel II are connected by multiple groups of arc-shaped rods. An annular seat I is sleeved on the top end of the filter barrel II. An annular seat II sleeved on the annular seat I is arranged on the inner wall of the barrel body. A circle of arc-shaped grooves are correspondingly arranged on the outer side wall of the annular seat I and the inner side wall of the annular seat II. Multiple groups of ball bearings are arranged in the two arc-shaped grooves. A toothed ring is sleeved on the filter barrel II below the annular seat I. A gear meshing with the toothed ring is arranged on the toothed ring. The gear is driven by a motor I;

[0008] A motor II is arranged on the top of the barrel body. A vertical pipe penetrating the bottom walls of the filter barrel I and the filter barrel II is arranged on the output shaft of the motor II. The vertical pipe is sleeved on the air inlet pipe on the bottom wall of the barrel body. Crushing knife groups are arranged on the vertical pipes in the filter barrel I and the filter barrel II. Scrapers and blowing pipes connected to the vertical pipes are arranged on the inner bottom walls of the filter barrel I and the filter barrel II. Air outlet holes are evenly arranged on the side walls of the blowing pipes.

[0009] Preferably, the scraper and the blowing pipe are respectively arranged on both sides of the vertical pipe. One end of the blowing pipe is hermetically arranged. The other end of the blowing pipe is communicated with the internal opening of the vertical pipe. A check valve is arranged at the end of the blowing pipe connected to the vertical pipe.

[0010] Preferably, bearing I sleeving on the vertical pipe is arranged on the bottom walls of the filtering barrel I and the filtering barrel II. A sleeve is arranged at the bottom end of the vertical pipe and sleeving on the air inlet pipe. A bearing II sleeving on the outlet end of the air inlet pipe is used for connecting the sleeve and the air inlet pipe.

[0011] Preferably, the inner bottom wall of the barrel body is inclined, and the discharge pipe is connected to the lowest end of the inner bottom wall of the barrel body.

[0012] Preferably, a recessed part for accommodating the motor I is recessed inward on the side wall of the barrel body.

[0013] Preferably, the feed pipe is located directly above the opening of the filtering barrel I. The side walls of the filtering barrel I and the filtering barrel II are both solid structures, and the aperture of the bottom wall of the filtering barrel I is larger than that of the bottom wall of the filtering barrel II. Discharge pipes are arranged at the bottoms of the filtering barrel I and the filtering barrel II.

[0014] The beneficial effects of the present invention are as follows: In the present invention, the filtering barrel I and the filtering barrel II drive the materials inside them to rotate clockwise, while the crushing knife group rotates counterclockwise. Since the rotation directions of the above two are opposite, the crushing knife group finally fully contacts the materials in the filtering barrel I and the filtering barrel II to crush them. The crushed materials are sifted through the sieve holes on the bottom walls of the filtering barrel I and the filtering barrel II, achieving the purpose of multi-stage screening and multi-stage crushing of the materials at the same time. The vertical pipe drives the scraper to sweep the materials on the inner bottom walls of the filtering barrel I and the filtering barrel II, preventing them from accumulating for a long time and blocking the apertures of the bottom walls of the filtering barrel I and the filtering barrel II and affecting the subsequent screening work. And when the scraper sweeps the materials, the subsequent rotating blowing pipe can cover the area swept by the scraper. At this time, the exhaust fan introduces strong air flow into the air inlet pipe and the vertical pipe, and then sprays out from the blowing pipe and the air outlet holes, thereby blowing the inner bottom walls of the filtering barrel I and the filtering barrel II after being scraped by the scraper, playing a forced blowing role, and further preventing the apertures of the bottom walls of the filtering barrel I and the filtering barrel II from being blocked by the materials, facilitating the subsequent screening work of the materials. At the same time, some of the blown materials can be lifted, facilitating the rotating crushing knife group to crush them again. Description of the Drawings

Detailed Embodiments

[0017] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0018] A crushing and sieving device for veterinary drug production includes a barrel body 1, wherein a discharge pipe is arranged at the bottom of the barrel body 1, and a feed pipe is arranged at the top thereof:

[0019] A filter barrel I 2 and a filter barrel II 3 are arranged in parallel up and down in the barrel body 1, wherein the filter barrel I 2 is directly above the opening of the filter barrel II 3, and the filter barrel I 2 and the filter barrel II 3 are connected by a plurality of arc-shaped rods 4. An annular seat I 5 is sleeved on the top end of the filter barrel II 3, and an annular seat II 6 sleeved on the annular seat I 5 is arranged on the inner wall of the barrel body 1. A circle of arc-shaped grooves are correspondingly arranged on the outer side wall of the annular seat I 5 and the inner side wall of the annular seat II 6. A plurality of balls 7 are arranged in the two arc-shaped grooves, and a toothed ring 8 is sleeved on the filter barrel II 3 below the annular seat I 5. A gear 9 meshing with the toothed ring 8 is arranged on the toothed ring 8, and the gear 9 is driven by a motor I 10;

[0020] A motor II 11 is arranged at the top of the barrel body 1. A vertical pipe 12 penetrating the bottom walls of the filter barrel I 2 and the filter barrel II 3 is arranged on the output shaft of the motor II 11, and the vertical pipe 12 is sleeved on an air inlet pipe 13 on the bottom wall of the barrel body 1. Crushing knife groups 14 are arranged on the vertical pipe 12 in the filter barrel I 2 and the filter barrel II 3. Scrapers 15 and purge pipes 16 connected to the vertical pipe 12 are arranged on the inner bottom walls of the filter barrel I 2 and the filter barrel II 3, and air outlet holes are uniformly arranged on the side walls of the purge pipes 16.

[0021] The scraper 15 and the purge pipe 16 are respectively arranged on both sides of the vertical pipe 12. One end of the purge pipe 16 is sealed. The other end of the purge pipe 16 is communicated with the internal opening of the vertical pipe 12, and a check valve is arranged at the end of the purge pipe 16 connected to the vertical pipe 12.

[0022] In this embodiment, bearings I sleeved on the vertical pipe 12 are arranged on the bottom walls of the filter barrel I 2 and the filter barrel II 3. A sleeve 17 sleeved on the air inlet pipe 13 is arranged at the bottom end of the vertical pipe 12, and the sleeve 17 and the air inlet pipe 13 are connected by a bearing II sleeved on the outlet end of the air inlet pipe 13.

[0023] As Figure 1 shown, the inner bottom wall of the barrel body 1 is inclined, and the discharge pipe is connected to the lowest end of the inner bottom wall of the barrel body 1. The inclined inner bottom wall of the barrel body 1 facilitates the flow of materials to the discharge pipe for discharge.

[0024] As Figure 1 shown, a recessed portion for accommodating the motor I 10 is recessed inward on the side wall of the barrel body 1.

[0025] In this embodiment, the feed pipe is located directly above the opening of the filtering barrel I2. The side walls of both the filtering barrel I2 and the filtering barrel II3 are solid structures, and the aperture diameter of the bottom wall of the filtering barrel I2 is larger than that of the bottom wall of the filtering barrel II3. Discharge pipes are provided at the bottoms of both the filtering barrel I2 and the filtering barrel II3.

[0026] During use, veterinary medicinal materials are introduced into the filtering barrel I2 through the feed pipe. At this time, the motor II11 drives the vertical pipe 12 to rotate on the bearing I and the bearing II, thereby driving the crushing knife group 14, the scraper 15, and the purging pipe 16 to rotate counterclockwise. The motor I10 drives the filtering barrel II3 to rotate through the gear 9 and the toothed ring 8. At this time, the filtering barrel II3 drives the arc-shaped groove on the annular seat I5 to slide on the ball 7, and also drives the filtering barrel I2 to rotate together through the arc-shaped rod 4, finally causing the filtering barrel I2 and the filtering barrel II3 to rotate clockwise;

[0027] Then, when the filtering barrel I2 and the filtering barrel II3 drive the materials inside them to rotate clockwise, and the crushing knife group 14 rotates counterclockwise. Due to the opposite rotation directions of the above two, finally the crushing knife group 14 fully contacts the materials in the filtering barrel I2 and the filtering barrel II3 to crush them. The crushed materials fall through the sieve holes in the bottom walls of the filtering barrel I2 and the filtering barrel II3, achieving the purpose of multi-level screening and multi-level crushing of the materials while screening them;

[0028] Among them, the vertical pipe 12 drives the scraper 15 to sweep the materials on the inner bottom walls of the filtering barrel I2 and the filtering barrel II3, preventing them from accumulating for a long time and blocking the aperture diameters of the bottom walls of the filtering barrel I2 and the filtering barrel II3 and affecting the subsequent screening work. And when the scraper 15 sweeps the materials, the subsequently rotating purging pipe 16 can cover the area swept by the scraper 15. At this time, the suction fan introduces strong air flow into the air inlet pipe 13 and the vertical pipe 12, and then sprays out from the purging pipe 16 and the air outlet holes, thereby blowing the inner bottom walls of the filtering barrel I2 and the filtering barrel II3 that have been scraped by the scraper 15 to perform a forced purging function, thereby preventing the aperture diameters of the bottom walls of the filtering barrel I2 and the filtering barrel II3 from being blocked by the materials, facilitating the subsequent screening work of the materials. At the same time, some of the purged materials can be lifted, facilitating the rotating crushing knife group 14 to perform re-crushing work on them.

[0029] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
