Induced-draft traditional Chinese medicinal material pulverizer with convenient-to-disassemble induced draft fan

Abstract

The invention discloses an induced-draft traditional Chinese medicinal material pulverizer with a convenient-to-disassemble induced draft fan. The induced-draft traditional Chinese medicinal material pulverizer comprises a pulverizer body and the induced draft fan, wherein the material falling end of the pulverizer body is connected with the induced draft fan by a material storage box, exhaust tubes and a cyclone separator, and a ventilation door used for adjusting air volume is arranged one exhaust tube, a pull-back separator is arranged on the exhaust tube, the material falling end of the pull-back separator is connected with a feed hopper, and the feed hopper is connected with the pulverizer body; and an impeller of the induced draft fan can promptly clean dust by use of the centrifugal force. The induced-draft traditional Chinese medicinal material pulverizer not only can complete returning and secondary crushing of coarse particles in one step to realize qualified material output, and more importantly, the assembly and disassembly technology of the induced draft fan is greatly improved to ensure that pressure exerted on the end surface of a screw shaft shoulder by similar nut parts is simply eliminated during disassembly of the induced draft fan, so that the problem that the induced draft fan in screw assembly is continually and automatically locked under the load action and therefore is difficult to disassemble is solved. The improved assembly and disassembly technology is particularly suitable for convenient disassembly of a large-scale fan in screw-threaded coupling, and the effect is particularly remarkable.

Description

technical field [0001] The invention relates to a Chinese herbal medicine pulverizer, in particular to a ventilating type Chinese herbal medicine pulverizer which does not accumulate dust in a fan and is easy to disassemble. Background technique [0002] Chinese herbal medicines need to be crushed when they are used as medicine or to extract active ingredients. The crushing process is an operation process of intense extrusion, knocking, friction, and shearing of materials, which will generate a lot of dust and heat up the materials strongly. Make the pulverizer quickly discharge the material to avoid excessive crushing, and at the same time realize the rapid cooling and sorting of the material, so that the product particles are uniform and at the same time return the coarse particles for secondary crushing, which is of great significance for improving product quality and reducing power consumption. [0003] Therefore, the crushing of Chinese herbal medicines is best to use t...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
