Dustproof equipment for mine area environment treatment

Abstract

The invention belongs to the field of mine area dust prevention, and particularly relates to dustproof equipment for mine area environment treatment. The dustproof equipment comprises dust suction equipment, a reversing air valve, a guide pipe, a rotating sleeve, an electric drive module B, a cylindrical shell, a dust suction pipe B, a spring A, a fixing block, a sliding block and a vortex sheet,wherein one dust suction pipe A of the dust suction equipment is connected with a ventilation pipe and an exhaust pipe installed at the top end of the dust suction equipment through the reversing airvalve, and a passage formed by the exhaust pipe and the ventilation pipe and a passage formed by the dust suction pipe and the ventilation pipe are switched through the reversing air valve. Accordingto the dustproof equipment, the flow direction of air flowing through the guide pipe is switched through the reversing valve, so that dust or fine particles on the hole wall are blown off to the holebottom in the process that the cylindrical shell moves into a drill hole, the dust or the fine particles on the hole bottom and the hole wall are effectively absorbed in the process that the cylindrical shell moves out of the drill hole, and therefore effective cleaning of the drill hole is achieved.

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
