Multi-stage totally-enclosed mining drilling and dust removal device

Abstract

The invention relates to a multi-stage totally-enclosed mining drilling and dust removal device, which comprises a box body, a gravity dust removal chamber, a water bath dust removal chamber and a spray dust removal chamber. In the coal mine drilling process, the generated dust-containing gas enters a gravity settling chamber through an air inlet, and larger granular dust is firstly removed, and discharged from a slag discharge hopper at the bottom under the action of the gravity and a baffle plate. And then the gas sequentially enters the water bath dust removal chamber and the spray dust removal chamber to realize the separation of gas and dust, and the discharge of water vapor is reduced through a gas-water separator at an air outlet. The clean gas in the gas-water separator enters an extraction pipeline, dust particles are deposited at the bottom of the container, and the dust particles are collected and discharged from a slag digging port. The multi-stage totally-enclosed mining drilling and dust removal device can effectively reduce the dust content of the construction roadway and avoid dust blocking the extraction pipeline, and has the advantages of low cost, easy operationand convenient movement.

Description

technical field [0001] The invention relates to the field of mine dust removal devices, in particular to a multi-stage fully enclosed mine drilling dust removal device. Background technique [0002] With the increase of coal mining depth and intensity, the demand for coal seam gas drainage is increasing. Drilling is one of the basic methods of gas control, and the demand for drilling engineering is also increasing. Because the coal seam is very dry, coal dust is flying when drilling, and the working environment is smoky. Operators must wear dust masks. Even so, it has also caused great harm to the health of the operating workers. In addition, dust enters the drilling rig equipment, which increases the probability of equipment failure and shortens the life of the drilling rig equipment. If the negative pressure of the extraction pipeline is used to directly suck the dust generated by drilling, the drilling and extraction pipeline will be blocked. [0003] At present, the ...

AI Technical Summary

Problems solved by technology

The spray dust removal effect is greatly affected by the dust type and its wettability, and it is often difficult to achieve the ideal dust removal effect with a single water mist

Foam dedusting equipment has many auxiliary pipelines, and the operation process is complicated, so the requirements for the formulation and addition ratio of foam agents are high

It is difficult to control the amount of foaming in field application, and the degree of foam adhesion at the orifice is greatly affected by the wind flow, the dust collection effect is poor, and the dust removal efficiency needs to be further improved

[0004] A large number of dust removal devices require electric motors to provide dust removal power, which increases energy consumption and reduces the explosion-proof ability of dust removal devices

[0005] Mine borehole dust collectors generally have the problems of high cost, complex structure, heavy and bulky, and difficult to transport
