Therefore, this utility model provides a magnetic separation and impurity removal device for drug granule raw materials. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides a magnetic separation device for removing impurities from pharmaceutical granule raw materials. Compared with the prior art, it has the following advantages:

[0016] 1. The magnetic separation and impurity removal device for the drug granule raw material uses a drive motor to rotate an eccentric wheel. The rotation of the eccentric wheel causes the T-plates on both sides to slide synchronously to both sides, achieving reciprocating sliding. The sliding of the T-plates causes the sliding plate, connecting rod, transmission gear, transmission rod, limiting block, and dispersing rod to reciprocate synchronously. This causes the limiting block to slide on the inner surface of the limiting groove, and simultaneously, the transmission gear rolls on the surface of the linkage gear plate, causing the transmission gear, transmission rod, and dispersing rod to begin rotating. This allows multiple sets of dispersing rods to reciprocate simultaneously. At this time, it begins to rotate on its own axis, which facilitates the dispersing of drug particles during the conveying process by multiple sets of dispersing rods. With the dispersing mechanism, driven by the drive motor, multiple sets of dispersing rods slide back and forth synchronously above the conveyor belt. Multiple sets of dispersing rods can disperse drug particles during the conveying process. Furthermore, with the linkage component, the dispersing rods can rotate on their own axis during the reciprocating sliding process, which can further improve the dispersing quality of drug particles and facilitate subsequent magnetic separation and impurity removal operations.

[0017] 2. The magnetic separation and impurity removal device for the drug granule raw material is equipped with a material blocking component. Under the drive of the control cylinder, the height of the material blocking plate can be flexibly adjusted. By adjusting the distance between the material blocking plate and the conveyor belt, the feeding rate and amount of the drug granule raw material entering the magnetic separator can be flexibly controlled, thereby improving the quality of magnetic separation and impurity removal of subsequent ferromagnetic impurities.

[0028] The drive component 42 is disposed on the top of the support plate 411 and is used to drive the sliding plate 412 to reciprocate.

[0029] Linkage component 43 is installed on the inner wall of support plate 411 and is used to drive the dispersing rod 416 to rotate.

[0033] In this embodiment, the drive assembly 42 includes a drive motor 421 mounted on the top of the support plate 411. One end of the output shaft of the drive motor 421 is fixedly connected to an eccentric wheel 422 via a coupling.

[0034] The drive motor 421 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0035] In this embodiment, the linkage assembly 43 includes a linkage plate 431 installed on the inner wall of the support plate 411.

[0036] The limiting groove 432 is used to slide and limit the limiting block 53.

[0037] With the dispersing mechanism 4 in place, multiple dispersing rods 416 are driven by the drive motor 421 to reciprocate synchronously above the conveyor belt. The multiple dispersing rods 416 can disperse the drug particles during the conveying process. Furthermore, with the linkage component 43 in place, the dispersing rods 416 can rotate during the reciprocating sliding process, thereby further improving the dispersing quality of the drug particles and facilitating subsequent magnetic separation and impurity removal operations.

[0038] In this embodiment, the material blocking assembly 3 includes a support plate 31 installed on the top of the conveyor frame 1. A control cylinder 32 is fixedly connected to the top of the support plate 31. A lifting plate 33 is fixedly connected to the bottom of the control cylinder 32 through a piston rod. A material blocking plate 34 is installed at the bottom of the lifting plate 33.

[0039] The control cylinder 32 is connected to an external air source via an air pipe;

[0040] A lifting rod for sliding limit is installed on the top of the lifting plate 33, and the lifting rod slides inside the bearing plate 31.

[0041] In this embodiment, the magnetic separation mechanism 2 includes a magnetic separator 21. A geared motor 22 is installed on the front side of the magnetic separator 21.

[0044] One side of the scraper 24 is in contact with the surface of the magnetic roller 23.

[0045] By setting up the material blocking component 3, the height of the material blocking plate 34 can be flexibly adjusted under the drive of the control cylinder 32. By adjusting the distance between the material blocking plate 34 and the conveyor belt, the feeding rate and amount of the drug particle raw material entering the magnetic separator 21 can be flexibly controlled, thereby improving the quality of magnetic separation and impurity removal of subsequent ferromagnetic impurities.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] During operation, the drug granules are first conveyed via the conveyor belt at the top of the conveyor frame 1. At this time, the drive motor 421 is started, driving the eccentric wheel 422 to rotate. The rotation of the eccentric wheel 422 causes the T-shaped plates 413 on both sides to slide synchronously to both sides, achieving reciprocating sliding. The sliding of the T-shaped plates 413 causes the sliding plate 412, connecting rod 415, transmission gear 52, transmission rod 51, limiting block 53, and dispersing rod 416 to reciprocate synchronously. This causes the limiting block 53 to slide on the inner surface of the limiting groove 432. Simultaneously, the transmission gear 52 rolls on the surface of the linkage tooth plate 433, causing the transmission gear 52, transmission rod 51, and dispersing rod 416 to begin rotating. This allows multiple sets of dispersing rods 416 to rotate simultaneously while reciprocating, facilitating the dispersing of the drug granules during the conveying process. The magnetic separation and impurity removal operation continues, and the dispersed drug granules are conveyed by the conveyor belt to the bottom of the baffle plate 34. At this time, the control cylinder 32 is activated to drive the lifting plate 33 and the baffle plate 34 to slide down synchronously. By adjusting the distance between the baffle plate 34 and the conveyor belt, the feeding rate and amount of the drug granules entering the magnetic separator 21 can be flexibly controlled. Subsequently, as the conveyor belt continues to convey, the drug granules fall onto the surface of the magnetic roller 23 under the influence of gravity. The magnetic roller 23 can adsorb the ferromagnetic impurities in the drug granules, and the drug granules will fall into the discharge trough 25 under the influence of gravity to achieve the discharge operation. The ferromagnetic impurities adsorbed on the surface of the magnetic roller 23 will rotate with the magnetic roller 23. When it rotates to the scraper plate 24, it will be scraped off into the collection plate 26 to achieve the centralized collection of ferromagnetic impurities.
