A kind of dust-proof equipment for environmental management in mining area

Abstract

The invention belongs to the field of dust prevention in mining areas, and in particular relates to a dust prevention equipment for environmental management in mining areas, which includes dust suction equipment, a reversing air valve, a conduit, a rotating sleeve, an electric drive module B, a cylindrical shell, a dust suction pipe B, and a spring A. Fixed block, slide block, and scroll piece, among which a dust suction pipe A of the dust collection equipment is connected with the ventilation pipe and the exhaust pipe installed on the top of the dust collection equipment through the reversing air valve, and the exhaust pipe and the ventilation pipe form a The path formed by the dust suction pipe A and the ventilation pipe is switched through the reversing air valve; the present invention uses the reversing valve to switch the flow direction of the air flowing through the conduit so that the cylindrical shell moves the hole wall to the borehole. The dust or fine particles on the surface are blown down to the bottom of the hole, and the dust or fine particles on the bottom of the hole and the wall of the hole are effectively absorbed during the movement of the cylindrical shell to the outside of the borehole, so as to achieve effective cleaning of the borehole.

Description

technical field [0001] The invention belongs to the field of dust prevention in mining areas, and in particular relates to a dust prevention device for environmental control in mining areas. Background technique [0002] Mine dust not only poses a threat to safe production, but also poses a threat to human health. Mine dust includes coal dust, rock dust, cement dust, stone dust and other dust. [0003] Coal dust can be divided into explosive coal dust and non-explosive coal dust. For the mining of explosive coal, dust prevention work is particularly important. Of course, no matter whether the mined coal dust is explosive or not, it is harmful to machines, people and the environment. It is harmful. Workers who inhale too much coal dust during the factory will get coal lung disease. Workers who inhale large amounts of rock dust (free silica) over a prolonged period of time can cause pneumoconiosis (silicosis). Workers inhale a large amount of cement dust during factory hours...

Problems solved by technology

For the method of high-pressure water injection into the borehole, it is necessary to wait for the borehole to dry after cleaning the borehole, resulting in long working hours and low efficiency
