Abstract

A kind of ultra-fine pulverizer, the frame is equipped with a crushing bin, the lower part of the frame is installed with a motor, the crushing bin is installed with a crushing knife, the crushing knife is installed on the rotating cutter head and driven by the motor, and the outer end of the rotating cutter head is installed There is a sieve plate; the door shaft is installed on the door, the middle part of the door is designed with the feeding port of the feeding hopper, and the inner side of the door is equipped with a fixed knife; the cooling water tank is installed on the outer side of the side plate and the top of the crushing bin . After adopting this technical solution, the material is impacted by the high-speed rotation of the crushing knife and the fixed knife in the bin body, and the blade cuts or smashes the material, and the material is crushed into a very fine powder. During the working process of the equipment, circulating cooling water is passed into the cooling water tank to reduce the working temperature in the tank and prevent the materials from being matured by high temperature.

Description

Super fine pulverizer

technical field

The utility model belongs to the technical field of pulverizers and relates to an ultrafine pulverizer.

Background technique

Many Chinese herbal medicines need to be pulverized after drying, and the finer the pulverization, the better the medicinal effect. At present, there are many types of pulverizers used for crushing Chinese herbal medicines. The pulverizers capable of superfine pulverization of more than 400 mesh generally have a complex structure. It is crushed by mechanical grinding, which is easy to produce high temperature and burn the material.

Contents of the invention

The utility model aims at the problem that in the prior art, the ultrafine pulverizer either requires a large investment or the pulverizing effect is not good, and provides an ultrafine pulverizer. The technical scheme of the machine is as follows:

A kind of ultra-fine pulverizer, a crushing bin is installed on the frame; a motor is installed on the lower part of the frame, a driving wheel is installed on the motor shaft, a feeding hopper is installed on the side of the crushing bin, and a discharge pipe is installed at the lower end to crush A crushing knife is installed in the chamber, a side plate is installed on one side of the crushing chamber, a door is installed on the other side, a shaft sleeve is installed in the middle of the side plate, a rotating shaft is installed in the shaft sleeve, and a driven wheel is installed at one end of the rotating shaft. It is connected with the drive wheel with a belt, the other end of the rotating shaft is equipped with a rotating cutterhead, the outer end of the rotating cutterhead is installed with a sieve disc, the middle part is equipped with a crushing knife, the door shaft is installed on the door, and one end of the door shaft is fixed on the bin On the door, the other end is fixed between the side walls of the crushing bin. The middle part of the bin door is designed with the feeding port of the feeding hopper, and a fixed knife is installed on the inner side of the bin door; Cooling water tank; the crushing knife installed on the cutter head has two layers inside and outside, and the fixed knife installed on the warehouse door also has two layers inside and outside.

After adopting this technical scheme, after the material enters the box body from the feed port, it is crushed in the box body. When the rotating cutterhead in the box body rotates at a high speed, it drives the movable crushing knife to rotate at a high speed, and its blade cuts or smashes the material. In addition, the material Driven by the movable pulverizer, it collides with the fixed pulverizer again at a high speed and smashes into pieces. After a period of time, the material is pulverized to a certain fineness and then falls from the sieve hole of the sieve plate into the discharge port. During the working process of the equipment, circulating cooling water is passed into the cooling water tank to reduce the working temperature in the tank and prevent the materials from being matured by high temperature.
