[0030] To perform screening of heparin sodium raw materials, please refer to [link / reference]. Figure 1-6This utility model provides a technical solution: a screening device for processing heparin sodium, including a screening box 1, a box door 2 on the front of the screening box 1, a support leg 3 fixedly installed at the bottom of the screening box 1, a screening mechanism 4 inside the screening box 1, and a feeding mechanism 5 extending from the inner wall of the screening box 1 to the top.

[0031] The screening mechanism 4 includes a drive assembly 41 and a connecting assembly 42. The drive assembly 41 is located inside the screening box 1 and extends to the bottom, while the connecting assembly 42 is located on top of the drive assembly 41.

Fixing seats 424 are fixedly mounted on the left and right sides of the first screen cylinder 421, the second screen cylinder 422, and the third screen cylinder 423. A sliding rod 425 is slidably mounted inside the fixing seat 424. A stop block 426 is fixedly mounted on the back of the sliding rod 425. A fixing spring 427 is fixedly mounted between the stop block 426 and the fixing seat 424. A fixing point is fixedly mounted on the end of the sliding rod 425 away from the baffle. A connecting plate 428 is provided, with a pin 429 fixedly installed on its back and a handle 4210 fixedly installed on its front. Limiting blocks 4211 are fixedly installed on the left and right sides of the first screen cylinder 421, the second screen cylinder 422, and the third screen cylinder 423. Connecting blocks 4212 are fixedly installed on the left and right sides of the collecting cylinder 413, the first screen cylinder 421, and the second screen cylinder 422 near the top.

[0035] Furthermore, the bottom of the fixing base 424 is inserted into the interior of the connecting block 4212, and the pin 429 is inserted into the interior of the fixing base 424 and the connecting block 4212, so as to facilitate the connection and fixation of the fixing base 424 and the connecting block 4212.

[0036] Furthermore, the limiting block 4211 has a through hole, and the end of the handle 4210 away from the connecting plate 428 is slidably installed inside the through hole of the limiting block 4211, which facilitates the sliding of the handle 4210 and the movement of the screen cylinder through the handle 4210. Example

[0037] To enable feeding and installation / disassembly of the third screen cylinder 423, this utility model provides another embodiment. Please refer to [the provided embodiment]. Figure 7 Furthermore, in conjunction with Embodiment 1, the feeding mechanism 5 includes a support block 51, which is fixedly installed on the left and right inner walls of the screening box 1. An electric telescopic rod 52 is fixedly installed on the top of the support block 51. An installation plate 53 is fixedly installed on the end of the electric telescopic rod 52 away from the support block 51. A feeding pipe 54 is fixedly installed inside the installation plate 53. A feeding hopper 55 is fixedly installed on the top of the feeding pipe 54, which facilitates the entry of heparin sodium raw material into the interior of the third screen cylinder 423. At the same time, it facilitates the sliding of the feeding pipe 54 when the third screen cylinder 423 is removed.

[0038] Furthermore, a through hole is provided at the top of the screening box 1 at the corresponding position of the feed pipe 54, and the feed pipe 54 is slidably installed inside the through hole to facilitate the sliding of the feed pipe 54 inside the screening box 1.

[0039] In actual operation, when this device is used, first open the box door 2, and use the handle 4210 on the first screen cylinder 421 to make the handle 4210 slide outward through the connecting plate 428 and the pin 429. Then place the first screen cylinder 421 on the collection cylinder 413 and insert the fixing seat 424 on the first screen cylinder 421 into the connecting block 4212 of the collection cylinder 413. Then release the handle 4210, and use the elastic force of the fixing spring 427 to move the connecting plate 428 to the rear side, and insert the pin 429 on the connecting plate 428 into the connecting block 4212 and the fixing seat 424. Based on the above principle, install the second screen cylinder 422 on the top of the first screen cylinder 421 in sequence, and install the third screen cylinder 423 on the top of the second screen cylinder 422.

[0040] Then, the electric telescopic rod 52 drives the mounting plate 53 to slide downwards, causing the mounting plate 53 to drive the feed pipe 54 to slide downwards, so that the feed pipe 54 slides into the interior of the third screen cylinder 423. Then, the box door 2 is closed, and the drive motor 415 is started, causing the drive motor 415 to drive the cam 416 to rotate. The cam 416 drives the sliding plate 412 to slide on the fixed rail 411, causing the sliding plate 412 to cooperate with the return spring 414, so that the sliding plate 412 drives the collecting cylinder 413 to reciprocate, so that the collecting cylinder... The feed cylinder 413 drives the first screen cylinder 421, the second screen cylinder 422, and the third screen cylinder 423 above to reciprocate. At the same time, heparin sodium raw material is added into the third screen cylinder 423 through the feed hopper 55. The heparin sodium raw material after being screened by the third screen cylinder 423 enters the second screen cylinder 422. The heparin sodium raw material after being screened by the second screen cylinder 422 enters the third screen cylinder 423. The heparin sodium raw material after being screened by the third screen cylinder 423 is discharged from the bottom of the box through the collection cylinder 413.

[0041] After screening, the box door 2 is opened, and the feed pipe 54 is slid upward by the electric telescopic rod 52. Then, by pulling the handle 4210, the pin 429 is pulled out from the connecting block 4212 and the fixed seat 424. Then, the third screen cylinder 423 is removed from the second screen cylinder 422. The above operation is repeated to remove the second screen cylinder 422 from the first screen cylinder 421, and then the first screen cylinder 421 is removed from the collecting cylinder 413.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
