Description

Technical Field

[0001] The utility model relates to the field of medicine processing, in particular to a granule screening device. Background Art

[0002] Medicines refer to substances used to prevent, treat, and diagnose human diseases, purposefully regulate human physiological functions, and have specified indications or functional indications, usage, and dosage. They include Chinese medicinal materials, Chinese herbal medicines, Chinese patent medicines, chemical raw materials and their preparations, antibiotics, biochemical drugs, radioactive drugs, sera, vaccines, blood products, and diagnostic drugs.

[0003] China's authorized patent announcement number: CN 220371534 U records "a granule screening device for pharmaceutical production", which is equipped with a soft brush assembly inside the screen cylinder, which is used to clean the residual medicine on the inner wall of the screen cylinder and break up the agglomerated particles.

[0004] However, there are still the following defects and shortcomings in the application process:

[0005] The inside of the screen drum can be cleaned by a soft brush, but the effect of breaking up lumps is relatively poor because the soft brush itself is relatively soft. If you want to break up the lumps by rotating the soft brush, the soft brush needs to have a very fast rotation speed. Only when the rotation speed is fast enough can the soft brush have enough impact force. However, this device is mainly used for screening raw materials and has a limited rotation speed, so its own crushing effect will be affected.

[0006] Therefore, it is necessary to provide a new granule screening device to solve the above technical problems. Utility Model Content
