Description

Drug particle screening device Technical Field The utility model relates to the technical field of medicine preparation, in particular to a medicine particle screening device. Background The medicine granule is prepared by mixing the raw materials (the Chinese medicine is an extract) with a certain proportion of auxiliary materials, and preparing the mixture into granules with the required size by using water or ethanol and the like as wetting agents through a granulator. In the course of treatment, the quantity of medicine granule is very important, consequently the size requirement to every medicine granule is higher, consequently needs to use sieving mechanism to get rid of the less or great medicine granule of external diameter after the granulator pelletization shaping to guarantee the medicine quantity and the treatment of treating diseases, for example current chinese patent of authorizing the bulletin number CN217963411U just discloses a drum-type medicine granule screening machine for medicine pelletization, including box and drum sieve, the outside of drum sieve is provided with the supporting ring, the both sides of box inner wall bottom all are provided with the supporting wheel, the supporting ring is in contact with the supporting wheel, the right side at box inner wall top is connected with the supporting shoe, the top of supporting shoe is connected with the right side rotation of drum sieve bottom, the left side of box bottom is connected with the screw thread piece. This drum-type medicine grain screening machine for medicine pelletization is jacked the left side of drum sieve through drive screw to make the drum sieve become incline state, the inside medicine grain of drum sieve is rolled to the right side because of the reason of gravity, thereby can be convenient take out the inside remaining medicine grain of drum sieve, thereby with the inside clean up of drum sieve, guarantee the screening effect of follow-up medicine grain, can block outside debris and dust when equipment is used through the case lid, prevent that the medicine grain from being polluted by outside debris, guaranteed the quality of medicine grain.
