A kind of Chinese medicine raw material powder preparation device

Abstract

A device for preparing traditional Chinese medicine raw material powder, which is sequentially provided with a first-stage grinding hammer, a second-stage grinding hammer, a third-stage grinding hammer and an air delivery device in a casing, the first-stage grinding hammer includes a first hammer body And a rectangular hammer head, the angle of inclination between the rectangular hammer head and the first hammer body is 20-45 degrees, a grinding table is provided in the casing corresponding to the first-stage grinding hammer, and the third grinding hammer is provided with a grinding table. A partition is set between the primary grinding hammer and the gas conveying device, a regrinding tank is provided between the partition and the third-stage grinding hammer, and a powder separation chamber is set in the casing, and the powder A coarse powder return pipe is arranged between the sorting chamber and the second-stage grinding hammer. Pipe connections. The traditional Chinese medicine raw material powder preparation device provided by the present invention can avoid high temperature generated during repeated grinding process, and can not generate dust and waste gas pollution at the same time.

Description

technical field [0001] The invention relates to a device for preparing raw material powder of traditional Chinese medicine. Background technique [0002] In the process of preparing Chinese patent medicines, the smaller the powder particles of Chinese medicine raw materials after crushing, the easier it is for the active ingredients of Chinese medicine raw materials to be further extracted and utilized. [0003] The existing preparation method of traditional Chinese medicine powder is generally to pulverize with a pulverizer first, and then sieve 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 grinding chamber is provided with screens half-surrounding the rotor from the bottom and both sides, therefore, it can simultaneously realize screening during the grinding process, However, when t...

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
