Dust removal device for ventilation system of coal mine well

Abstract

The invention relates to the technical field of mine purification, in particular to a dust removal device for a ventilation system of a coal mine shaft, which comprises a moving frame movably arranged in a ventilation shaft, a moving mechanism is mounted on the moving frame, a dust collection mechanism is mounted in the middle of the moving frame, and the dust collection mechanism is matched with the moving mechanism. A sweeping frame is rotationally installed at the end of the moving frame, a sweeping mechanism is movably arranged on the sweeping frame, and an ecological negative ion emitter is installed at the end, away from the sweeping frame, of the moving frame. By arranging the moving mechanism, through adjustment of the moving mechanism, the whole dust removal device can adapt to ventilation hoistways of different sizes in a coal mine ventilation system, and the whole dust removal device is convenient to use; by arranging the dust collection mechanism, in the adjustment process of the moving mechanism, the distance between the dust collection mechanism and the inner wall of the ventilation shaft in the coal mine well ventilation system can be adjusted, and dust on the inner wall of the ventilation shaft in the coal mine well ventilation system can be conveniently adsorbed by the dust collection mechanism.

Description

technical field [0001] The invention relates to the technical field of mine purification, in particular to a dust removal device for a coal mine ventilation system. Background technique [0002] Mine is a general term for shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Occasionally, the inclined shafts, shafts, and flat tunnels in the underground development of mines are also called mines. The determination of the size of the well field, the production capacity of the mine and the service life of each mine is one of the key issues that must be solved in the design of the mine itself. In order to ensure the safety of underground personnel during underground operations, effective ventilation is usually required. Mine ventilation is the basic work in mining. Ventilation can reduce the content of harmful gases in the underground, while maintaining the necessary oxygen supply for underground workers. [0003] Du...

AI Technical Summary

Problems solved by technology

Because some coal seams are soft and the pulverized coal particles are very fine, a large amount of pulverized coal must be produced in the coal mine, and when the pulverized coal passes through the ventilation system, it is easy to adhere to the ventilation shaft in the ventilation system and the filter screen in the ventilation shaft. , it is easy to affect the ventilation efficiency of the entire ventilation system, and it is easy to affect the staff inside the coal mine, and there are certain safety hazards
