Air-cooled pulverizer

Abstract

The invention provides an air-cooled pulverizer which comprises a coarse crushing mechanism, a fine crushing mechanism, a power mechanism and an air cooling mechanism, the coarse crushing mechanism comprises a hopper and a coarse crushing wheel, and a discharge port of the hopper is connected with a feed port of the coarse crushing wheel; the fine crushing mechanism comprises an integral cylindrical screen and a fine crushing tool bit, and a discharge port of the coarse crushing wheel is connected with a feed port of the integral cylindrical screen; the air cooling mechanism comprises a fan, a first pressure sensor, a second pressure sensor and a temperature sensor. By adopting the air-cooling series crushing design, the traditional Chinese medicinal materials are crushed in one step by utilizing the series crushing design of the coarse crushing mechanism and the fine crushing mechanism, and the crushing quality is stable; the crushing process is intelligently controlled through a pressure sensor and a temperature sensor, higher screen strength and screening effect are achieved through an integral cylindrical screen, dust-free crushing and dust overflow prevention are achieved through sealing and negative-pressure crushing, the risks of dust explosion and dust-related occupational diseases are reduced, and continuous crushing operation is achieved.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to an air-cooled pulverizer. Background technique [0002] Traditional Chinese medicine refers to the substances that are used to prevent, treat, diagnose diseases and have the functions of rehabilitation and health care under the guidance of the theory of traditional Chinese medicine. Traditional Chinese medicine mainly comes from natural medicine and its processed products, including botanical medicine, animal medicine, mineral medicine and some chemical and biological products. Since Chinese medicines are mostly botanicals, there is a saying that "all medicines are based on herbs". Since the reform of new drugs, my country has vigorously developed traditional Chinese medicine; and emphasized the promotion of complementary and coordinated development of traditional Chinese medicine and Western medicine. As an important part of the excellent cultural treasure house of the Chi...

Problems solved by technology

[0004] Therefore, both jet milling and grinding milling have the following defects: 1. It is necessary to coarsely crush Chinese herbal medicines in advance, and jet milling needs to crush Chinese herbal medicines to fine powder; 2. It is necessary to manually control the feeding speed, and if it is too slow, it will affect the crushing speed , too fast will lead to material blockage; 3. The dust generated during the crushing process can easily overflow into the operating space, bringing the risk of dust explosion and dust-related occupational diseases

Airflow milling also has the following disadvantages: 1. It is necessary to adjust the airflow according to the density and particle size of the coarse powder of different medicinal materials, otherwise the coarse powder cannot be fully crushed or the large-weight coarse powder particles cannot be blown up and crushed and aggregate to cause blockage; 2. Airflow milling cannot be installed Large-mesh sieve, the quality of the obtained Chinese herbal medicine powder is not guaranteed

The grinding and crushing also has the following disadvantages: 1. The installed screen is a detachable single-piece screen, which has a small structural strength, a small sieving area, easy damage and slow sieving speed; 2. A large amount of heat will be generated during the grinding process. , the crushing operation cannot be carried out continuously for a long time, otherwise the equipment will be damaged
