Technical Field
[0001] This invention relates to the field of screening equipment technology, and in particular to a screening device for the production of veterinary drug granules. Background Technology
[0002] In the production and processing of veterinary drug granules, granule screening devices are often used to screen the granules. However, current screening devices use multiple screening plates inside the screening mesh to screen the granules. The granules that do not pass the screening are stored on the screening plates, which require separate collection and processing. This operation method is very inconvenient and affects the use of the device. Summary of the Invention
[0003] The purpose of this invention is to provide a screening device for the production of veterinary drug granules.
[0004] The technical problem of this invention is mainly solved by the following technical solution: A screening device for producing veterinary drug granules includes a housing. A cylindrical cylinder, sealed at one end, is horizontally arranged inside the housing. A motor I driving the cylinder to rotate is located at the sealed end of the cylinder. An inlet near the cylinder's open end and an outlet near the sealed end are located on the cylinder's sidewall. Multiple screening zones are evenly arranged on the cylinder's sidewall between the inlet and outlet. A sleeve, also sealed at one end, is fitted over the cylinder's end. The sleeve is driven by a driving mechanism, and a sleeve fitted on both sides of one of the screening zones is located inside the sleeve's open end. A feed pipe is provided on a sleeve between two sets of circular rings. A crossbar extending into the cylinder is provided at the sealing end of the sleeve. Two sets of circular plates corresponding to the circular rings are fixed to the end of the crossbar by bearings. An annular plate is also provided between the two sets of circular plates. Multiple sets of T-shaped rods on the same side as the sealing end are also provided inside the cylinder. The T-shaped rods pass through the corresponding circular plates and are connected to the annular plates. A spring is sleeved on the T-shaped rods on the back of the circular plates. A discharge hopper is provided at the bottom of the sleeve. A discharge port communicating with the discharge hopper is provided on the bottom wall of the sleeve between the two sets of circular rings.
[0005] Preferably, the driving mechanism includes protrusions on both sides of the top of the sleeve, and the two sets of protrusions are provided with screw holes for screwing the lead screw. The lead screw is driven by motor II. The housing is also provided with a slide rod passing through the through holes on the two sets of protrusions.
[0006] Preferably, the top of the box is provided with an operation opening corresponding to the feed inlet, and the operation opening is provided with a switch door.
[0007] Preferably, the bottom of the discharge hopper is provided with a corrugated hose that is inclined downwards and connected to the discharge pipe on the side wall of the box.
[0008] Preferably, the aperture of the screening area sidewall on the same side as the cylindrical sealing end is larger than the aperture of the screening area sidewall on the other side.
[0009] Preferably, the gap between the inner arc wall of the ring and the outer arc wall of the cylinder is no more than 0.1 cm. The inner arc wall of the ring is uniformly provided with receiving grooves with a cross section of superior arc. The receiving grooves are provided with ball bearings that abut against the outer wall of the cylinder. A rubber ring that is sleeved on the cylinder is also provided on one side of the ring.
[0010] Preferably, the feed pipe is equipped with a solenoid valve, and the bottom end of the feed pipe is provided with an arc-shaped notch that fits onto the top surface of the cylinder.
[0011] The beneficial effects of this invention are as follows: This invention uses a movable sleeve to drive components such as a circular ring, a circular plate, and an annular plate to move within a cylinder, thereby driving the raw material to be screened between two sets of circular plates to move within the cylinder. This achieves the purpose of progressively screening the material by pushing the material within the cylinder from right to left to multiple screening areas with different screen hole sizes. Simultaneously, the final screened material can be pushed to the discharge port within the cylinder. The movement of the circular and annular plates facilitates the discharge of the final screened material. This invention eliminates the need to collect and process unscreened material from each screening area; it only requires discharge into the next screening area for further screening. This facilitates the collection and processing of materials screened in each screening area, and the final screened material can be discharged through the discharge port, thus simplifying the use of the device.

[0014] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0015] A screening device for producing veterinary drug granules includes a housing 1. A cylindrical cylinder 2, sealed at one end, is horizontally arranged inside the housing 1. A motor 13, designed to drive the cylinder 2's rotation, is located at the sealed end. An inlet 4 near the cylinder 2's open end and an outlet 5 near the cylinder 2's sealed end are located on the side wall of the cylinder 2. Multiple screening zones 6 are evenly arranged on the side wall of the cylinder 2 between the inlet 4 and the outlet 5. Figure 1 , 2 As shown in Figures 1 and 3, the aperture of the sidewall of the screening area 6 on the same side as the sealing end of the cylinder 2 is larger than the aperture of the sidewall of the screening area 6 on the other side.
[0016] The cylinder 2 is further fitted with a sleeve 7 with a sealed end. The sleeve 7 is driven by a drive mechanism 8. The sleeve 7 has a ring 9 fitted on both sides of one set of screening areas 6 inside the open end of the sleeve 7. A feed pipe 10 is provided on the sleeve 7 between the two sets of rings 9. A crossbar 11 extending into the cylinder 2 is provided at the sealed end of the sleeve 7. The end of the crossbar 11 is fixed with two sets of circular plates 12 corresponding to the rings 9 by bearings 13. An annular plate 14 is also provided between the two sets of circular plates 12. Multiple sets of T-shaped rods 15 are also provided inside the cylinder 2 on the same side as its sealed end. The T-shaped rods 15 pass through the corresponding circular plates 12 and are connected to the annular plate 14. A spring 16 is fitted on the T-shaped rods 15 on the back of the circular plates 12. A discharge hopper 17 is also provided at the bottom of the sleeve 7. A discharge port 18 communicating with the discharge hopper 17 is provided on the bottom wall of the sleeve 7 between the two sets of rings 9.
[0017] The drive mechanism 8 includes protrusions 81 on both sides of the top of the sleeve 7. The two sets of protrusions 81 are provided with screw holes that are screwed to the lead screw 82. The lead screw 82 is driven by the motor II 83. The housing 1 is also provided with a slide rod 84 that passes through the through holes on the two sets of protrusions 81.
[0018] like Figure 1 , 2 As shown in Figures 1 and 3, the top of the box body 1 is provided with an operation opening 19 corresponding to the feed port 4, and the operation opening 19 is provided with a switch door.
[0019] In this embodiment, the bottom of the discharge hopper 17 is inclined downward and is provided with a corrugated hose 20 that is connected to the discharge pipe 21 on the side wall of the box 1.
[0020] In this embodiment, the gap between the inner arc wall of the ring 9 and the outer arc wall of the cylinder 2 is no more than 0.1 cm to prevent severe friction between the two when the cylinder 2 rotates inside the ring 9. At the same time, the small gap between the two also makes it less likely for material to flow out through the gap. The inner arc wall of the ring 9 is uniformly provided with receiving grooves with a cross-section of an arc. The receiving grooves are provided with ball bearings 22 that abut against the outer wall of the cylinder 2. A rubber ring 23 is also provided on one side of the ring 9 and is fitted onto the cylinder 2. When the metal cylinder 2 rotates inside the soft rubber ring 23, there will be no rigid friction between the two, thereby reducing the wear rate of the cylinder 2. At the same time, the rubber ring 23 can effectively prevent the material screened through the side wall aperture of the screening area 6 from flowing into the gap between the cylinder 2 and the ring 9 and flowing out.
[0021] In this embodiment, a solenoid valve is provided on the feed pipe 10, and an arc-shaped notch is provided at the bottom end of the feed pipe 10 to fasten to the top surface of the cylinder 2.
[0022] During feeding, motor II83 drives screw 82 to rotate on boss 81, while boss 81 drives sleeve 7 to move to the right. At this time, sleeve 7 drives ring 9 and rubber ring 23 to slide to the right on cylinder 2. Sleeve 7 also drives circular plate 12 and annular plate 14 to move to the right inside cylinder 2 via crossbar 11, ultimately as follows. Figure 2 As shown, the feed pipe 10 is located directly above the feed inlet 4. At this time, the operating opening 19 and the feed pipe 10 can be opened to introduce granular raw materials into the cavity formed between the two sets of circular plates 12 inside the cylinder 2 through the feed pipe 10.
[0023] When the material is being screened, the drive mechanism 8 moves the sleeve 7, circular plate 12, and annular plate 14 to the left. Simultaneously, the two sets of circular plates 12 push the material to be screened to the left within the cylinder 2, ultimately... Figure 1As shown, at this time, the feed inlet 4 is located on the right side of the circular plate 12, and the feed pipe 10 is closed. Therefore, during subsequent screening, the material in the cylinder 2 between the two sets of circular plates 12 will not flow out through the feed inlet 4 and the feed pipe 10. In this embodiment, the rightward-moving circular plate 12 pushes the material located between the two sets of circular plates 12 from right to left to each screening area 6. When the two sets of circular rings 9 and the circular plate 12 are located on both sides of a certain screening area 6, the sleeve 7 stops moving, and the motor I3 drives the cylinder 2 to roll on the ball bearings 22 in the circular ring 9. The rotating cylinder 2 and the screening area 6 screen the material. At this time, when the circular plate 12 and the rotating cylinder When friction occurs, the rotational force of the cylinder 2 can drive the circular plate 12 to rotate on the bearing 13, preventing the circular plate 12 from rotating with the cylinder 2 and causing severe friction and damage between them. The qualified particles fall into the sleeve 7 opening between the two sets of rubber rings 23 after being screened through the side wall aperture of the screening area 6. Finally, they fall under the influence of gravity and enter the discharge hopper 17 through the discharge port 18, and then are discharged through the corrugated hose 20 and the discharge pipe 21. In this embodiment, the material in the cylinder 2 is pushed from right to left to move one by one to the screening areas 6 with different screen hole sizes for screening, thereby achieving the purpose of screening the material step by step.
[0024] When the final screened product needs to be discharged, the drive mechanism 8 moves the sleeve 7, circular plate 12, and annular plate 14 to the left. Simultaneously, the two sets of circular plates 12 push the screened product to the left within the cylinder 2. When the T-shaped rod 15 contacts the sealed end of the cylinder 2, the sleeve 7, through the crossbar 11, drives the circular plate 12, annular plate 14, and T-shaped rod 15 to continue moving to the left, ultimately... Figure 3 As shown, the right circular plate 12 is located to the right of the discharge port 5, while the sealing end of the cylinder 2 abuts against the T-shaped rod 15 to limit the leftward movement of the annular plate 14, so that it is located to the left of the discharge port 5. At the same time, the leftmost circular plate 12 compresses the spring 16, thereby restricting the screened material at the discharge port 5 by the moved annular plate 14 and the right circular plate 12. When opened, the screened material will enter the discharge hopper 17 through the discharge port 5 at the bottom of the cylinder 2 and be discharged. The rotating cylinder 2 can also be used to accelerate the discharge efficiency and effect of the screened material.
[0025] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
