Mining geomancy-matched scattering-type dust removing device

Abstract

Disclosed is a mining geomancy-matched scattering-type dust removing device. The mining geomancy-matched scattering-type dust removing device consists of a spraying annular cylinder, an atomizing nozzle, an air sending cylinder body, a rotating bracket and a telescopic bracket. The air inlet end of the air sending cylinder body is connected with an air sending hose. The air outlet end of the air sending cylinder body is provided with a metal head plug. Two rings of annular air seams of different directions are formed in the periphery of the metal head plug. The air sending cylinder body is externally provided with the spraying annular cylinder body in a sleeved mode. The water outlet end of the spraying annular cylinder body is provided with the atomizing nozzle. The water inlet end of therear part of the spraying cylinder body is connected with a high-pressure water inlet pipe. The air inlet hose and the high-pressure water inlet pipe are each provided with an air pressure gauge, a water pressure gauge and an adjusting valve. A filter net is arranged at the front end of the high-pressure water inlet pipe. Fast joints are arranged at an air inlet of the air inlet hose and a waterinlet of a high-pressure hose. The height of a bracket can be vertically adjusted, and adjusting is convenient according to the scene situation. The mining geomancy-matched scattering-type dust removing device is small in size, good in atomizing effect, simple in operation and convenient to use, can be flexibly installed in every dust outburst position in a mine, and is suitable for underground coal mine dust removing work.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a scattering spray device used for dust removal in underground coal mines. Background technique [0002] Underground coal mine dust is the main factor that causes occupational diseases, coal dust explosion, spontaneous combustion and damage to equipment, and reduces on-site visibility. Currently, underground dust removal mostly uses devices such as internal and external spraying of roadheaders, coal seam water injection, and dust removal fans, but these devices have their own limitations. The dust removal effect is not ideal. For example, the nozzles of the internal and external spraying of the roadheader are easily blocked, and the dust removal efficiency is very low; the coal seam water injection system has a complicated process, a large amount of engineering, and high cost; the dust removal fan equipment is too large and heavy, it is very inconvenient to move and use, and there are ele...

Problems solved by technology

[0002] Underground coal mine dust is the main factor that causes occupational diseases, coal dust explosion, spontaneous combustion and damage to equipment, and reduces on-site visibility. Currently, underground dust removal mostly uses devices such as internal and external spraying of roadheaders, coal seam water injection, and dust removal fans, but these devices have their own limitations. The dust removal effect is not ideal

For example, the nozzles of the internal and external spraying of the roadheader are easily blocked, and the dust removal efficiency is very low; the coal seam water injection system has a complicated process, a large amount of engineering, and high cost; the dust removal fan equipment is too large and heavy, it is very inconvenient to move and use, and there are electrical safety hazards

The water-vapor linkage system has a good application prospect, but the current technology is not yet mature, and the phenomenon of pressure water backfilling the air duct often occurs and the water consumption of the system is too large
