Device for separating coarse powder from fine powder after crushing of traditional Chinese medicine components

Abstract

The invention discloses a device for separating coarse powder from fine powder after crushing of traditional Chinese medicine components, relates to the technical field of medicine processing, and solves the problems that the operation is troublesome when the existing coarse powder and fine powder are separated, a cyclone separator is only suitable for the condition of more products and is difficult to adapt to small-batch processing, the equipment is complicated, and the cost is higher. The device comprises: an outer shell; an air supply device which is arranged in the left side of the outer shell; a driving part which is fixedly connected to the interior of the left side of the outer shell; a regrinding assembly which is arranged on the left side of the interior of the outer shell; a screening assembly which is arranged on the right side of the interior of the outer shell; and a material returning assembly which is arranged in the screening assembly. Materials with various particle sizes can be screened out, so that the discharging particle size is guaranteed; and meanwhile, grinding operation does not need to be conducted again during screening, so that operation is reduced, the working efficiency is improved; and meanwhile, the device is simple in structure, low in cost and suitable for small-batch production.

Description

technical field [0001] The invention relates to the technical field of medicine processing, in particular to a device for separating coarse and fine powder of traditional Chinese medicine components after crushing. Background technique [0002] Traditional Chinese medicine is some animals, plants, minerals, etc. that have a certain therapeutic effect in nature and have been gradually discovered by the Chinese nation in the long history. In the pharmaceutical process of modern medicine, the ingredients in traditional Chinese medicine are often extracted to obtain drugs with stable curative effects. , in the process of extracting the active ingredients of traditional Chinese medicine, the traditional Chinese medicine is generally crushed first, then sieved, and then processed and extracted accordingly. [0003] For example, application number: CN201720123962.5 The utility model provides a traditional Chinese medicine extraction equipment, which includes an ultrafine pulverizer...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a device for separating coarse and fine powders of traditional Chinese medicine components after pulverization, so as to solve the problem that the existing coarse and fine powders proposed in the background technology are generally separated by a cyclone separator, and only two particle sizes of coarse and fine can be formed after separation. , for those with large particle size, it needs to be separated and then re-grinded, which is troublesome to operate. At the same time, the cyclone separator is only suitable for a large amount of products, and it is difficult to adapt to small batch processing. At the same time, the equipment is complicated and the cost is high.
