Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical intermediate processing equipment, and specifically relates to a grinding device for pharmaceutical intermediates. Background Art

[0002] In the process of drug preparation, pharmaceutical intermediates refer to compounds produced in the intermediate steps of drug synthesis. These intermediates are formed from raw material compounds through a series of organic synthesis steps. They are temporary products in the pharmaceutical process and usually undergo further transformation and treatment in subsequent steps to eventually form the final drug product. Pharmaceutical intermediates play a key role in drug synthesis because they directly affect the yield and purity of the final drug. At the same time, the synthesis of intermediates also requires special chemical techniques and conditions to ensure high yield and high selectivity. The synthesis of pharmaceutical intermediates is usually an important link in the drug preparation process and is directly related to the quality and effect of the drug.

[0003] When preparing pharmaceutical intermediates, grinding equipment is usually used. However, existing grinding equipment has a disadvantage, that is, after the grinding equipment crushes and grinds the Chinese medicine body, the Chinese medicine powder will be discharged through the discharge port, and some Chinese medicine powder will often remain near the discharge port. Long-term accumulation will lead to cross infection, and manual cleaning is relatively troublesome and will also delay the processing progress. Therefore, a grinding equipment for pharmaceutical intermediates is proposed to solve the above problems. Utility Model Content

[0038] The grinding equipment for pharmaceutical intermediates of the utility model:

[0039] When the user wants to use the device, first connect the set driving motor 31 to the external power supply, and control the reciprocating rotation of the driving motor 31 to drive the threaded screw 32 connected to the output end to rotate. When the threaded screw 32 rotates, it drives the external meshing sliding sleeve 33 to move, and the sliding mounting block 34 installed outside the sliding sleeve 33 also moves accordingly. The sliding mounting block 34 is limited by the four limiting rods 36, so that the sliding mounting block 34 can slide radially within the stroke unit of the threaded screw 32 and drive the nylon brush 4 installed on one side. When the nylon brush 4 moves, the connecting block 52 connected to one side of the nylon brush 4 by two connecting rods 37 is driven. The connecting block 52 is limited by the two side sliding rods 51. When the sliding mounting block 34 drives the nylon brush 4 to move, with the assistance of the connecting block 52, the nylon brush 4 can clean the residual Chinese medicine powder in the lower hopper 2 back and forth.
