Mine explosion-proof type dedusting device

Abstract

The invention belongs to the technical field of dedusting devices, in particular to a mine explosion-proof type dedusting device. The mine explosion-proof type dedusting device comprises a dedusting box body and an air exhaust device, wherein the air exhaust device is provided with a fixed base; an air exhaust fan is arranged in the fixed base; high-pressure water spraying nozzles are arranged onblades of the air exhaust fan, and are connected with a high-pressure water conveying pipe; the air exhaust fan is connected with a brush head, a blind hole is formed in each blade of the air exhaustfan, and a steel ball is arranged in each blind hole; each high-pressure water spraying nozzle is communicated with the corresponding blind hole; a high-pressure water conveying pipe is connected withthe blind hole; a filtering plate is arranged in the dedusting box body, a spraying device is arranged at the top part of the dedusting box body, the bottom part of the dedusting box body is providedwith a blowdown port, and a sewage bag is arranged at the outer side of the blowdown port; the filtering plate is connected with the interior of the dedusting box body through a No.2 spring, and every two filtering plates are connected by a spring rope; the brush head is in contact with each filtering plate; the spraying device is provided with a water spraying pipe, and an atomizing spray head is arranged on the water spraying pipe. The mine explosion-proof type dedusting device has the advantages that the steel balls are pushed by water pressure to compress the springs, so as to reduce theimpact force of the water pressure, and prolong the service life of the air exhaust fan.

Description

technical field [0001] The invention belongs to the technical field of dust removal devices, in particular to an explosion-proof dust removal device for mines. Background technique [0002] With the large-scale development of mining, metallurgy, glass manufacturing, ceramics, refractory materials, building materials and other industries, the hazards of dust are gradually recognized by people, which brings unsafe factors to production, such as mechanical wear; coal, flour and other dust are easy to Cause combustion and explosion, etc., causing huge economic losses; quartz and dust containing free silica may cause pneumoconiosis to workers who have been engaged in dust operations for a long time, seriously damage their health, and even lose their ability to work or die prematurely. [0003] Patent document 1: A mine water jet explosion-proof dust removal device, application number: 201510735203X [0004] In the above-mentioned Patent Document 1, an explosion-proof dust remova...
