Abstract

The invention discloses an ultra-micro magnetized foam drilling dust remover, which is applicable to the underground dust removal of a coal mine. The dust remover is mainly composed of a drilling stopper, a first-stage dust settling device and an ultra-micro magnetized foam dust capturing device. The drilling stopper is connected with the first-stage dust settling device. The first-stage dust settling device is connected with the ultra-micro magnetized foam dust capturing device. By means of the first-stage dust settling device connected onto the drilling stopper, large-particle coal dust generated in the drilling process of coal and rock mass is led out through a conical cylinder; the coal dust and gas enter the ultra-micro magnetized foam dust capturing device and are gradually subjected to dust settling in three compartments of the dust collecting device; compared with the prior art, the dust remover has the advantages of simple structure, safety for operation and convenience for use; and by adopting the graded dust settling theory in a dry-process and wet-process combined way, the dust removing process and the drilling process are carried out synchronously, and the efficiency for settling whole dust, in particular respiratory dust, is high.

Description

technical field

[0001] The invention relates to a dust remover, particularly in the field of dust removal, in particular to an ultra-micro magnetized foam drilling dust remover suitable for underground coal mines. Background technique

[0002] The hazards of coal mine dust are not only manifested in the occurrence of coal dust or gas coal dust explosion accidents, affecting operation safety and endangering the ecological environment around the mining area, but also in causing workers to suffer from pneumoconiosis. More than 90% of China's coal mines are underground mines. During the whole process of coal production, there are occupational hazards such as productive dust and productive poisons, which have caused some workers to suffer from silicosis, coal workers' pneumoconiosis and occupational poisoning to varying degrees. and other occupational diseases. According to incomplete statistics, the dust occupational hazard in my country's coal industry ranks first among all ma...
