Coal mine downhole dedusting device

Abstract

The invention discloses a coal mine downhole dedusting device comprising a shell, gas inlet covers, a plurality of cloth bag assemblies and an exhaust port. The gas inlet covers are arranged on the left side and the right side of the shell. The bottom of the shell is fixedly connected with a dispersion disc. The interior of the shell is fixedly connected with a lower fixing plate. The lower surface of the lower fixing plate is fixedly connected with a spraying head. The upper surface of the lower fixing plate is fixedly connected with the multiple cloth bag assemblies. The exhaust port is formed in the top of the shell. A connecting rod is hinged to the upper surface of the lower fixing plate. A driven shaft is arranged on the right side of the connecting rod. Dusty gas in a mine is suckedinto the dispersion disc by a gas pump through the gas inlet covers, finally exhausted into clear water, and is subjected to preliminary dedusting through the clear water, the dusty gas and the clearwater make contact more fully by arranging the dispersion disc, and thus the dedusting efficiency is improved; the cloth bag assemblies are rapped by a hammerhead, so that dust particles attached tothe inner walls of the cloth bag assemblies are separated from the cloth bag assemblies, the cloth bag assemblies are cleared, and the trouble of manual clearing of the cloth bag assemblies is eliminated.

Description

technical field [0001] The invention relates to the field of coal mine mechanical equipment, in particular to an underground coal mine dust removal device. Background technique [0002] During the mining and production of coal mines, a large amount of dust will be generated and fill the entire operation site, which not only reduces visibility, affects production progress and operation safety, but more importantly, these dusts seriously affect the health of workers. Coal mine workers have become the victims of pneumoconiosis. High-risk groups, the relevant state departments attach great importance to dust hazards, strictly formulate relevant standards for dust emissions, strictly control dust concentration, and reduce dust hazards. Therefore, how to effectively reduce the amount and concentration of dust has become a concern of coal mining enterprises; traditional dust removal equipment Generally, the dust is removed by filtering the air, or the dust is condensed and dropped ...
