Small efficient dust remover used incoal mine

Abstract

The invention provides a small efficient dust remover used in a coal mine. The small efficient dust remover comprises a dust removal box and an induced draft fan connected with the side face of the dust removal box, a screen plate is connected to the upper end of the inner wall of the dust removal box, a bottom plate is connected to the lower end of the inner wall of the dust removal box, and an overhaul door is arranged on the outer wall of the dust removal box; shaking blocks are uniformly distributed at the bottom of the screen plate, a shaking rod is connected with the side faces of the shaking blocks and is connected with a shaking rod driving motor, the shaking rod driving motor is arranged on the side face of the dust removal box, a bag cap is connected to the bottom of the side face of each shaking block and connected with a filter bag, a supporting rod is connected to the bottoms of the shaking blocks and is connected with the bottom plate, a dust collecting box is arranged at the bottom of the bottom plate, the induced draft fan is connected with the dust removal box through an induced draft pipe, the induced draft fan is installed on a support, and an upper computer is arranged on the surface of the support. The small efficient dust remover is capable of effectively reducing dust content of coal air, low in manufacturing cost and convenient to operate, and safety equipment is arranged to prevent dust explosion.

Description

technical field [0001] The invention belongs to a dedusting device, in particular to a small-scale high-efficiency deduster used in coal mines. Background technique [0002] Because gas threatens the safety of coal mining, it is an important link before coal mining to drill holes in the wall of coal mines to drain gas from coal seams. For some soft coal seams, only dry drilling can be used, and the compressed air blowing process is used to make the coal powder and compressed air generated during drilling spray out along the gap between the drill pipe and the hole wall. Although the flow rate of dust blowing gas is not large, the energy of the compressed air is large, and the airflow formed has a strong impact force, and the amount of dust carried is as high as 3000mg / m3, resulting in a very harsh environment on the working face, which seriously threatens the health of the workers. [0003] Existing technologies such as Chinese invention authorization, authorization announce...
