A kind of traditional Chinese medicine powder preparation device

Abstract

A traditional Chinese medicine powder preparation apparatus is characterized in that a first-stage grinding hammer, a second-stage grinding hammer, a third-stage grinding hammer and an air conveying device are sequentially arranged in a shell, the first-stage grinding hammer comprises a first hammer body and a rectangular hammerhead, an inclination angle between the rectangular hammerhead and the first hammer body is 15-35DEG, a grinding table is arranged corresponding to the first-stage grinding hammer in the shell, a separation plate is arranged between the third-stage grinding hammer and the air conveying device, a return grinding groove is arranged between the separation plate and the third-stage grinding hammer, the shell is provided with a powder sorting chamber, a coarse powder return tube is arranged between the powder sorting chamber and the second grinding hammer, the powder sorting chamber comprises a powder outlet, the powder outlet is connected with a powder collecting chamber, and the powder collecting chamber is connected with the first-stage grinding hammer through an air channel tube. The traditional Chinese medicine powder preparation apparatus can avoid generation of high temperature in the repeated grinding process, and does not generate dust or exhaust gas pollution.

Description

Technical field [0001] The invention relates to a device for making traditional Chinese medicine raw materials into powder. Background technique [0002] In the preparation process of Chinese patent medicines, the smaller the powder particles of the Chinese medicine raw materials are crushed, the easier the effective ingredients of the Chinese medicine raw materials will be further extracted and utilized. [0003] The existing preparation method of traditional Chinese medicine powder is generally to pulverize with a pulverizer, and then sieving with a sieving machine, which requires the use of two different equipments, so the production efficiency is not high. [0004] Chinese patent CN100542676C provides an axial flow hammer mill. The outer circumference of the rotor in the milling chamber is provided with screens that half-enclose the rotor from the bottom and both sides. Therefore, it can achieve screening during the crushing process. However, when the requirements for powder par...

AI Technical Summary

Problems solved by technology

[0003] The existing preparation method of traditional Chinese medicine powder is generally crushed with a pulverizer first, and then sieved with a sieving machine, which requires the use of two different equipment, so the production efficiency is not high

[0004] Chinese patent CN100542676C provides an axial flow hammer mill, in which the outer periphery of the rotor in the crushing chamber is provided with screens half-surrounding the rotor from the bottom and both sides, therefore, it can simultaneously realize screening during the crushing process, However, when the powder particles that need to be prepared are relatively small, for example, when powder particles of more than 200 meshes are required to be prepared, this structure is difficult to control the dust of the sieved powder particles, that is, it is easy to cause waste of powder dust. In addition, this technical solution also Not convenient for continuous production

[0005] When preparing high-mesh powder particles, such as powder particles above 200 mesh, it is necessary to solve the problem that the high temperature generated by long-term grinding may damage the raw materials of traditional Chinese medicine, and the problem of how to collect the prepared fine powder
