A kind of Chinese herbal medicine powder production equipment

Abstract

The invention discloses Chinese herbal medicine powder production equipment. According to the equipment, a first-stage grinding hammer, a second-stage grinding hammer, a third-stage grinding hammer and an air delivery device are sequentially arranged in a casing, the first-stage grinding hammer comprises a first hammer body and a rectangular hammer head which are inclined at 15-35 degrees, a grinding table corresponding to the first-stage grinding hammer is arranged in the casing, a separation plate is arranged between the third-stage grinding hammer and the air delivery device, a back grinding tank is arranged between the separation plate and the third-stage grinding hammer, the casing is provided with a powder separation chamber, a coarse powder backflow pipe is arranged between the powder separation chamber and the second-stage grinding hammer, the powder separation chamber comprises a powder outlet connected with a powder collection chamber, and the powder collection chamber is connected with the first-stage grinding hammer through an air flue pipe. With the adoption of the Chinese herbal medicine powder production equipment, the high temperature is prevented from being produced during repeated grinding, and meanwhile, dust and waste gas pollution can be avoided.

Description

technical field [0001] The invention relates to a device for making Chinese herbal medicine raw materials into powder. Background technique [0002] In the process of preparing Chinese patent medicines, the smaller the powder particles of Chinese herbal medicine raw materials after being pulverized, the easier it is for the active ingredients of Chinese herbal medicine raw materials to be further extracted and utilized. [0003] The existing preparation method of Chinese herbal 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, How...

AI Technical Summary

Problems solved by technology

[0003] The existing method of preparing Chinese herbal medicine powder is generally to crush 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 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 Chinese herbal medicines, and the problem of how to collect the prepared fine powder
