Technical Field
[0001] This utility model relates to the field of veterinary drug production equipment technology, and in particular to a particle screening device for veterinary drug granule production. Background Technology
[0002] Veterinary drugs refer to substances (including medicated feed additives) used to prevent, treat, diagnose animal diseases, or purposefully regulate animal physiological functions. In the production of veterinary drug granules, the uniformity of particle size has a significant impact on the efficacy and effectiveness of the veterinary drug. Most traditional veterinary drug granule screening devices use a single screening method, which cannot perform fine grading of the particles, resulting in large differences in particle size after screening. This can easily lead to clogging during the screening process, affecting the continuity and stability of screening. Therefore, this application proposes a particle screening device for the production of veterinary drug granules. Utility Model Content

[0024] Example 1
[0025] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes a granule screening device for veterinary drug granule production, including a housing 1 and a material primary screening mechanism disposed at the top of the housing 1. The material primary screening mechanism includes two fixed seats 2 fixed to the top of the housing 1, which provide stable support for the screening seat 3. The screening seat 3 is fixedly connected to the top of the two fixed seats 2, and a material storage box 4 is fixedly connected to the top of the two screening seats 3. The material storage box 4 is used to store the veterinary drug granules to be screened. A motor drive rod 8 passes through one side of the outer wall of the screening seat 3, and a servo motor 7 is fixedly connected to one end of the motor drive rod 8. The servo motor 7 drives the rotation of the screening wheel 10. The motor drive rod 8 is powered by a motor. Both ends of its outer wall are rotatably connected to limit seats 9, which limit and support the motor drive rod 8. Multiple screening wheels 10 are fixedly connected to the outer wall of the motor drive rod 8. Both ends of the outer wall of each screening wheel 10 are fixedly connected to the inner wall of the screening base 3 via through bearings 5, ensuring the screening wheels 10 can rotate flexibly. Multiple screening grids 11 are fixedly connected to both ends of the outer wall of each screening wheel 10. The screening grids 11 are used for preliminary screening of veterinary drug granules. A feed inlet 6 is fixedly connected to the center of the top of the material storage box 4, located above the box body 1 for convenient material input. A discharge port 12 is fixedly connected to the bottom of the screening base 3, through which the pre-screened material enters the box body 1.
[0026] Another point that needs to be described is, for example Figure 1 , Figure 3 and Figure 4As shown, the fine screening mechanism includes multiple screening plates 13 slidably connected to the inner wall of the housing 1 via sliding rods. One end of each screening plate 13 is fixedly connected to the other side of the inner wall of the housing 1 via a connecting joint 14.

The servo motors 15 drive the screening plates 13 to reciprocate through the connecting rods 16, rotating disks 17, rotating arms 18, and driving arms 19 to achieve screening of materials. Multiple screening plates 13 are slidably connected to the inner wall of the limiting ring 22 at the other end away from the sliding rod. One side of each of the two limiting rings 22 is fixedly connected to both sides of the inner wall of the box 1. The limiting rings 22 limit the movement of the screening plates 13 to ensure the stability of the movement of the screening plates 13. Two fixing frames 20 are fixedly connected to one side of the multiple screening plates 13 on the inner wall of the box 1. A connecting frame 25 is fixedly connected to one side of the inner wall of each of the two fixing frames 20. A guide plate 26 is fixedly connected between the two connecting frames 25. A baffle 21 is fixedly connected to the top of the connecting frame 25. The guide plate 26 is used to guide the flow direction of the material. The baffle 21 prevents the material from overflowing. A material guide trough 23 is fixedly connected to the inner wall of the box 1 below the multiple screening plates 13. A transmission pipe 24 is fixedly connected to one side of the bottom of the material guide trough 23. The transmission pipe 24 is located on one side of the guide plate 26. The screened material is discharged through the material guide trough 23 and the transmission pipe 24.
[0027] In this embodiment, the veterinary drug granules to be screened are poured into the material storage tank 4 through the feed port 6. The servo motor 7 is started, which drives the motor drive rod 8 to rotate. The motor drive rod 8 drives the screening wheel 10 to rotate. The screening grid 11 on the screening wheel 10 performs preliminary screening of the veterinary drug granules. The material after preliminary screening enters the box 1 through the discharge port 12. The servo motor 15 is started, which drives the screening plate 13 to reciprocate through the connecting rod 16, rotating disk 17, rotating arm 18 and drive arm 19 to further finely screen the material entering the box 1. The screened material is discharged through the guide chute 23 and the transmission pipe 24, completing the entire screening process.
