Explosion-proof-type dust collector for mine

Abstract

The invention discloses an explosion-proof-type dust collector for a mine, comprising a box body, a dust collecting and blowing system, an explosion-proof device, airflow distributing plates and an ash dumping drawer. The box body is in a cuboid structure and is provided with a tubesheet at the inner upper part, a space above the tubesheet forms an air purifying chamber, a space below the tubesheet forms a dust removing chamber, an air outlet is arranged at the rear end of the air purifying chamber, the dust collecting and blowing system is provided with a filter cartridge and a blowing device, the filter cartridge is arranged in the dust removing chamber, the tubesheet is arranged at the upper end of the filter cartridge, the blowing device is provided with a pulse valve, a blowing pipe, a nozzle, an air storage tank and a diversion device, the air storage tank is arranged at the outer side of the box body, the blowing pipe is located in the air purifying chamber and connected with the air storage tank through the pulse valve, the nozzle is arranged on the blowing pipe and arranged right above the upper end of the filter cartridge, the diversion device is arranged at the upper end of the filter cartridge, the airflow distributing plates are slantways arranged in the dust removing chamber and arranged below the lower end of the filter cartridge, the dust removing chamber is provided with an air inlet at the front end and provided with an ash dumping drawer hole at the lower part on one side, the ash dumping drawer is inserted in the hole, and the explosion-proof device is arranged at one side of the box body.

Description

technical field [0001] The invention relates to a mining explosion-proof filter and dust collector used in engineering excavation of coal mines, roadways, tunnels and the like. Background technique [0002] Most of the existing dust removal equipment used in many industries is a bag filter. This type of bag filter is mainly composed of a shell, a long cloth bag, a dust removal device and an ash hopper. In order to achieve the ideal dust removal effect, its volume is generally made very large. Due to the frequent movement of equipment during the excavation process of coal mining, roadways, tunnels and other projects, on the other hand, the space on site is limited, so the existing bag filter cannot be applied to the above occasions. If it is made into a smaller bag filter, its dust removal effect is poor, so it cannot meet the dust removal requirements of engineering excavation occasions such as coal mining and roadways and tunnels.
