Problems solved by technology

[0002] There are many types of pulverizers. The basic working principle is: in the material cavity, the high-speed rotating beating teeth or hammers are used to repeatedly beat and pulverize materials such as wheat and medicine. During this process, a large amount of heat will be generated in the cavity. , and continue to accumulate, it is easy to overheat the body and affect the service life of the pulverizer. In addition, the heat will be transmitted to the feed port to heat the material. Due to the effect of moisture in the material, it is easy to cause the material to re-condense during the pulverization process. , reducing the crushing efficiency

Abstract

The invention relates to an internal circulating air-cooled pulverizer, comprising an enclosure, a base and a motor, wherein a pulverizing cavity is formed in the enclosure, and a hammer rotor in the pulverizing cavity is driven by a motor through a main shaft to rotate and closed by a sieve plate; a circulating cooling air supply system formed by sequentially connecting a freeze dryer, a gas tank, a filter tank and an air compressor respectively supplies cooled gas A into the main shaft, the pulverizing cavity and a feeding hole through control valves, wherein the cooling gas A entering the main shaft cools the main shaft and a bearing through a first control valve K1 and is supplied to the sieve plate through the main shaft to cool the material in the pulverizing cavity and destroy a material gas-solid circulation layer; and gas B discharged from a discharge hole along with the material enters a dust separator, and separated gas C is returned to the air compressor, so that the cooling gas is circulated in the circulating cooling air supply system. The loss of energy is prevented, and the utilization rate of cold air is improved. The pulverizing efficiency is improved by over 10% compared with the existing pulverizer.

Description

technical field [0001] The invention relates to an internal circulation air-cooled pulverizer. Background technique [0002] There are many types of pulverizers. The basic working principle is: in the material cavity, the high-speed rotating beating teeth or hammers are used to repeatedly beat and pulverize materials such as wheat and medicine. During this process, a large amount of heat will be generated in the cavity. , and continue to accumulate, it is easy to overheat the body and affect the service life of the pulverizer. In addition, the heat will be transmitted to the feed port to heat the material. Due to the effect of moisture in the material, it is easy to cause the material to re-condense during the pulverization process. , reducing the crushing efficiency. [0003] For this reason, the application number 2009101642796 proposes an air-cooled high-efficiency energy-saving pulverizer, which is mainly composed of a feed hopper, a machine cover, a volute casing, a sc...
