A mine underground dust removal device

Abstract

The invention belongs to the technical field of mine underground drilling dust removal device, in particular to a mining underground dust removal device comprising a dust removal box, a cross plate, an annular square tube, clearing modules, an intake pipe, an exhaust pipe, a mud discharging module and shaking modules. The mud discharging module is installed at the bottom of the dust removal box. The top of the inner wall of the dust removal box is provided with a cross plate used for partitioning the dust removal box. The bottom of the inner wall of the dust removal box is provided with the annular square tube above the exhaust pipe. The tube wall on the top of the annular square tube are evenly provided with multiple second round holes used for air injection. The cross plate is evenly provided with multiple first round holes. The tops of the multiple first round holes are all provided with shaking modules. Each shaking module comprises an elastic collision ball, an extension spring and an arc rubber film. The arc rubber film is fixedly connected with the cross plate. According to the mining underground dust removal device, sprinkling adsorption and foam adsorption are conducted ondust, the contact time and the contact path between the dust and foam are prolonged, so that the removal efficiency of the dust generated by drilling is improved, the particulate matter content in air is effectively lowered, and health of workers is protected.

Description

technical field [0001] The invention belongs to the technical field of underground drilling dust removal equipment, in particular to an underground dust removal device for mines. Background technique [0002] With the continuous increase of mining depth, the gas gushing out of coal mines is getting bigger and bigger, and gas accidents are becoming more and more frequent, which has attracted great attention from the state. It is required to adopt gas pre-extraction measures in gas mines to prevent gas disasters. Due to the serious problem of dust pollution caused by gas pre-drainage drilling, it has become another important hidden danger that affects the health of workers and restricts mine safety production. At present, there are mainly two drilling techniques, wet and dry, among which wet drilling adopts hydraulic slag removal, and the dust pollution is relatively small. However, when the coal seam is mixed with gangue and soft and hard coal, the wet drilling hydraulic sla...

Problems solved by technology

However, this type of dust removal equipment removes dust by spraying, the efficiency of dust removal is low, and the quality of dust removal is low, and the dust generated by drilling cannot be effectively removed, which endangers the health of workers.
