Moveable mist spray and dust removal device in coal mine shaft

Abstract

The invention discloses a moveable mist spray and dust removal device in a coal mine shaft. The device comprises a base, wherein a dust removal box is arranged on the base, one side of the dust removal box is provided with an aspirated engine, the aspirated engine is provided with an aspirator pump, and the aspirator pump is communicated with a dust collection box arranged in the dust removal boxthrough an air suction pipeline; the dust removal box is communicated with an air exhaust pipeline, the air exhaust pipeline is connected with an air suction port of the aspirator pump on the dust collection box, and an air outlet of the aspirator pump is connected with a mixing box through a pipeline; the inner portion of the mixing box is provided with a water suction pump, and the water suctionpump is connected with a water storage tank arranged on the dust collection box through a water pipe; the mixing box is further provided with an outlet, and the outlet is connected with an atomizingnozzle. The moveable mist spray and dust removal device in the coal mine shaft detects the dust concentration in the mine shaft through a dust detection sensor, when the detected dust concentration exceeds a preset value, the aspirated engine absorbs the dust in the mine shaft into the dust collection box; and a controller controls the aspirator pump and the water suction pump to work simultaneously, thereby further reducing the dust concentration in the mine shaft.

Description

technical field [0001] The invention relates to the technical field of mine dust prevention, in particular to a movable spray dust suppression device under a coal mine. Background technique [0002] In the mining of minerals, the focus is generally placed on fully mechanized mining and tunneling working faces, while dust control between roadways is ignored. And dust may be produced in various stages of mining. For example, in the mining of coal mines, most of the coal dust in the roadway comes from the coal block transportation process. The belt conveyor is the main equipment for mechanized mine raw coal transportation. When reloading between belt conveyors (the reloading point is called the reloading point), because the belt has a certain speed and there is a drop between the two belts (for example, about 0.5 meters), the coal block is affected by the roadway wind during the falling process. Action Coal dust is suspended and spreads in the air. [0003] In the related art...
