High-efficiency ventilation device for coal mining

Abstract

The invention discloses a high-efficiency ventilation device for coal mining. The high-efficiency ventilation device comprises a ventilation pipeline, wherein an air pump is arranged on one side of the ventilation pipeline; an atomization dust-settling mechanism is arranged in the ventilation pipeline and comprises a water storage tank; one side of the water storage tank is connected with a waterpump; one end of the water pump is connected with a water supply pipeline; one end, which is positioned in the ventilation pipeline, of the water supply pipeline is connected with a water flow pressurizer; a plurality of atomizers are arranged at the bottom of the water flow pressurizer; connecting shafts are arranged in the atomizers; connecting pieces are arranged in the connecting shafts; and springs are arranged on the outer sides of the connecting pieces in a sleeving manner. According to the high-efficiency ventilation device disclosed by the invention, a filtering mechanism and an atomization dust removal mechanism are arranged on the conventional coal mining ventilation device, so that damage of dust, impurities and toxic gases in the mine to the device is reduced, the problem thatthe ventilation pipeline of the device is blocked due to dust accumulation is solved, damage of fine particulate matters entering the device to the ventilation device is reduced, the ventilation efficiency is improved, and air in the mine is circulated.

Description

technical field [0001] The invention belongs to the technical field of coal mining, and in particular relates to a high-efficiency ventilation device for coal mining. Background technique [0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to dig underground roadways to mine coal. This is an underground coal mine. When the distance between the coal seam and the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate the coal. This is an open-pit coal mine, and the coal can be divided into four types: peat, lignite, bituminous coal and anthracite. [0003] During the long-term use of the existing coal mining ventilation device, some dust, burning oil, inhalable particles and harmful gases in the mine will cause certain corrosion to the ventil...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-efficiency ventilation device for coal mine mining to solve the problem that a large amount of dust and cinders will accumulate inside the device when the above-mentioned existing coal mine ventilation device is used for a long time, causing the blockage of the ventilation pipe and affecting the use of the device.
