Description

Technical Field

[0001] The utility model belongs to the technical field of veterinary drug production, in particular to a premix production screening device. Background Art

[0002] Tylvalosin tartrate premix is ​​a common antibiotic used to prevent and treat poultry and livestock. It can effectively treat diseases such as wheezing, gastroenteritis, and swine erysipelas in the treatment of pigs. During the production process of Tylvalosin tartrate premix, it needs to be screened to improve the uniformity of the particles.

[0003] When screening the existing tyvalocin tartrate premix, a circular vibrating screen or a linear vibrating screen is usually used. After the premix particles are placed on the screen plate, the particle size of the premix is ​​screened by vibration to separate larger or smaller particles. During long-term use observation, it is found that when the existing premix is ​​used with a linear vibrating screen, the premix is ​​usually added to the screen plate continuously. When a large amount of premix particles are added, they will be stacked on the screen plate, resulting in a high thickness of the premix particles on the screen plate, which will wrap uneven particles during screening and affect the screening effect.

[0004] To this end, the utility model provides a premix production screening device. Utility Model Content

This step can increase the air intake range of the air intake pipe 31 by setting the air guide hood 4 to connect the air intake pipe 31, so as to increase the contact surface of the dust entering the air intake pipe 31, so as to improve the dust removal effect.

[0029] like Figure 5As shown, the side wall of the fixed frame 12 is fixedly connected with a collecting groove 5; the collecting groove 5 is arranged near the end of the blanking plate 17; a pull-out box 51 is placed in the collecting groove 5; the collecting groove 5 and the pull-out box 51 are in sliding cooperation; during operation, when unqualified particles fall on the surface of the blanking plate 17, they will slide into the pull-out box 51, and at this time the pull-out box 51 can collect the unqualified particles.

At this time, the counterweight 6 can increase the weight of the bottom of the fixed leg 13 to make its position more stable. In this step, by setting the counterweight 6 to connect the fixed leg 13, the position can be made more stable by increasing the weight of the bottom of the fixed leg 13, thereby reducing the situation of position movement during vibration screening.

[0031] like Figure 1 As shown, an observation window 7 is provided on the top of the dust cover 33; during operation, the material screening situation inside the dust cover 33 can be observed through the observation window 7. By setting the observation window 7, the material screening situation on the surface of the first sieve plate 15 can be easily observed to facilitate adjustment.

[0032] Working principle: Start the vibration motor 14 to drive the vibration screen box 1 to vibrate. At this time, add the tylvalosin tartrate premix particles into the feed hopper 19, and then start the first electric push rod 110 to drive the slide plate 112 to move back and forth.

When the feed port 113 and the feed hopper 19 are misaligned, the particles can be blocked and remain in the feed hopper 19, and the particles can fall onto the feed plate 114 in batches. When the particles fall from the feed plate 114 to the surface of the first sieve plate 15, The surface will start to vibrate. The holes on the first sieve plate 15 are larger than the holes on the second sieve plate 16, so that large particles can remain on the surface of the first sieve plate 15 and then be discharged from the first discharge port 115. Qualified particles will fall on the surface of the second sieve plate 16. Under the vibration of the second sieve plate 16, smaller unqualified particles will fall on the surface of the lower feed plate 17 below. Qualified particles will be discharged from the second discharge port 116. The second electric push rod 2 is started to drive the rack 21 to reciprocate. At this time, the rack 21 contacts the gear 23 to make it slide back and forth. At this time, the gear 23 The lever 24 can be driven to swing back and forth. When the material falls on the surface of the first screen plate 15, the lever 24 swings above the first screen plate 15 to flatten the material. When the material vibrates on the surface of the first screen plate 15, the mutual collision and friction between the particles will generate dust. At this time, the dust cover 33 will block the dust inside. The vacuum pump 32 is started to drive the air flow from the air intake pipe 31 into the filter box 3. At this time, the filter screen in the filter box 3 can filter the dust. When the air flow enters the air intake pipe 31, it will pass through the air guide cover 4, and the air guide cover 4 is in an expanded state. Increase the air intake range of the air inlet pipe 31. When unqualified particles fall on the surface of the discharge plate 17, they will slide into the pull-out box 51. At this time, the pull-out box 51 can collect the unqualified particles. After the collection is completed, the pull-out box 51 is pulled out to take out the particles, and then the pull-out box 51 is put back into the collection tank 5. When the vibrating screen box 1 is placed in the specified position, the fixed leg 13 will contact the ground. At this time, the counterweight block 6 can increase the weight of the bottom of the fixed leg 13 to make its position more stable.
