AI Technical Summary
During the granulation process, the binder will stick the powder raw materials to the inner wall of the granulation tank. The stirring paddle and cutting blade have processing dead corners, resulting in ungranulated residues and uneven composition, which may cause cross-contamination of veterinary drug granules.
The system employs a scraper and wall-scraping drive mechanism. A third motor drives a second incomplete gear to engage the slide plate and rack, enabling the scraper to periodically scrape off powder from the inner wall. Simultaneously, the spray gun rotates synchronously with the scraper to spray adhesive, ensuring uniform mixing.
It effectively removes residual powder from the inner wall, ensures uniform particle composition, prevents cross-contamination, and improves granulation efficiency and quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulator technology, and more specifically, to a high-efficiency wet mixing granulator. Background Technology
[0002] The high-efficiency wet mixing granulator is a device that turns powdered materials into granules through an integrated "mixing-granulation-drying" operation. It is widely used in the manufacture of veterinary drug granules. The specific process is as follows: veterinary drug powder is added to the granulation tank, and a binder (such as starch paste, povidone solution, etc.) is evenly sprayed into the material through a spray gun. At the same time, the stirring paddle and the cutting blade work together. After granulation, the granules are taken out by the feeder.
[0003] However, due to the adhesive's stickiness, the powdered raw materials will adhere to the inner wall of the tank during the granulation process. Furthermore, the stirring paddle and cutting blade only process the raw materials, leaving certain processing dead zones and resulting in ungranulated residues. This can lead to uneven composition of veterinary drug granules within the same batch and cross-contamination between different batches, thus affecting the quality of veterinary drug production. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-efficiency wet mixing granulator to solve the problem that, due to the adhesive's certain stickiness, the powder raw material will stick to the inner wall of the tank during the granulation process, and the stirring paddle and cutting blade only process the raw material, resulting in certain processing dead corners and the formation of ungranulated residue.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency wet mixing granulator, including a granulation tank, a tank cover on the top of the granulation tank, a first motor fixedly installed in the middle of the bottom surface of the granulation tank, a second motor fixedly installed at the bottom of the outer side of the granulation tank, a stirring paddle fixedly connected to the output end of the first motor, a cutting blade fixedly connected to the output end of the second motor, a scraper and a wall scraping drive mechanism provided on the tank cover, the scraper fitting against the inner wall of the granulation tank, and the wall scraping drive mechanism being used to drive the scraper to repeatedly scrape off the powder raw materials adhering to the inner wall of the granulation tank.

[0007] Preferably, a feeder is provided on the side of the granulation tank opposite to the second motor, and a support leg is fixedly connected to the bottom of the granulation tank.
[0008] Preferably, the scraping drive mechanism includes a rotating shaft and a third motor. The rotating shaft passes through and is rotatably connected to the middle of the can lid. A first incomplete gear is fixedly connected to the top end of the rotating shaft, and a scraper is fixedly connected to the bottom end. A linear slide rail is also fixedly installed on the top surface of the can lid. A slide plate is slidably connected in the linear slide rail. A first rack is provided on the side of the slide plate facing the first incomplete gear. The first incomplete gear meshes with the first rack. A groove is opened on the top surface of the slide plate. Parallel second racks are provided in the groove. A second incomplete gear is provided between the two second racks. The output end of the third motor is fixedly connected to the center of the second incomplete gear. During the rotation of the second incomplete gear, it alternately meshes with the two second racks.
[0009] Preferably, the central angle range of the reciprocating rotation of the scraper is 180°-270°.
[0010] Preferably, the scraping drive mechanism further includes a protective cover, which is fixedly installed on the tank lid, and the third motor is fixedly installed on the protective cover.
[0011] Preferably, the can lid is further provided with a drug addition mechanism, which includes a spray gun. The spray gun is fixedly installed on the horizontal part of the scraper.

The end of the second hose away from the transition tube is fixedly connected to a delivery pump.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention uses a third motor to drive the second incomplete gear to rotate, and through alternating meshing with the second rack, drives the slide plate to slide back and forth along the linear slide rail. During this process, the first rack slides back and forth to mesh with the first incomplete gear, so that the scraper periodically scrapes off the powder raw material adhering to the inner wall of the granulation tank around the scraping wall drive mechanism, fully processing the powder raw material into veterinary drug granules, ensuring the uniformity of the granule composition, and preventing cross-contamination between different batches of veterinary drugs.
[0014] This invention uses a pump to deliver adhesive through a second hose, a transition hose, and a first hose, spraying it into the granulation tank via a spray gun. Simultaneously, the spray gun rotates back and forth with the scraper, ensuring that the powdered raw material is evenly mixed with the adhesive, preventing localized over-wetting or drying, and ultimately forming particles with more uniform particle size, thus improving the granulation efficiency and quality of the granulator.
