A kind of Chinese herbal medicine powder raw material production equipment

Abstract

A Chinese herbal medicine powdery raw material producing device is disclosed. A first-stage grinding hammer, a second-stage grinding hammer, a third-stage grinding hammer and a gas transporting apparatus is successively disposed in a machine shell. The first-stage grinding hammer comprises a first hammer body and a rectangular hammer head. An inclined angle between the rectangular hammer head and the first hammer body is 15-35 degrees. A grinding bench corresponding to the first-stage grinding hammer is arranged in the machine shell. A separating plate is disposed between the third-stage grinding hammer and the gas transporting apparatus. A back-grinding groove is arranged between the third-stage grinding hammer and the separating plate. The machine shell is provided with a powder sorting chamber. A crude powder backflow pipe is disposed between the powder sorting chamber and the second-stage grinding hammer. The powder sorting chamber includes a powder outlet which is connected to a powder collecting chamber. The powder collecting chamber is connected to the first-stage grinding hammer through an air flue pipe. The Chinese herbal medicine powdery raw material producing device can avoid generation of a high temperature during a repeatedly grinding process without pollution of dust and waste gas.

Description

technical field [0001] The invention relates to a production equipment for preparing Chinese herbal medicine powder raw materials. Background technique [0002] In the process of preparing Chinese patent medicines, the raw materials of Chinese herbal medicines need to be made into powder. The smaller the powder particles after crushing, the easier it is for the active ingredients of the raw materials of Chinese herbal medicines to be further extracted and utilized. [0003] The existing preparation method of powdery raw materials of Chinese herbal medicines 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 s...

Problems solved by technology

[0003] The existing preparation method of powdery raw materials of Chinese herbal medicines is generally firstly pulverized with a pulverizer, 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 Chinese herbal medicines, and the problem of how to collect the prepared fine powder
