Coal mine underground ventilation device based on environmental protection

Abstract

The invention relates to the field of ventilation devices of mines or tunnels, in particular to an underground coal mine ventilation device based on environmental protection. An air inlet is defined in the ventilation pipeline, and the air flowing direction is set to be the first direction; the ventilation device comprises a first filter screen, an air blocking assembly, a scraper assembly, a drainage assembly and an ash removal assembly. The air blocking assembly is installed on the ventilation pipeline in a sliding mode, an ash removal hole is formed in the air pipeline, and the ash removal assembly is configured to drive the ash removal assembly to move synchronously when the scraper assembly moves. According to the ventilation device, when more solid wastes such as dust or other harmful impurities are gathered on the surface of the first filter screen, in order to improve the air cleanliness under the mine and improve the environment, the first filter screen moves to a certain position under the action force of wind, and the scraper is used for scraping the dust on the first filter screen; the ventilation device serves as environmental protection equipment, and the development of the ventilation device is beneficial to atmospheric cleaning and environmental protection.

Description

technical field [0001] The invention relates to the field of ventilation devices for mines or tunnels, in particular to a coal mine underground ventilation device based on environmental protection. Background technique [0002] During the mining process, a large amount of solid waste, such as fine dust, is generated. Mine ventilation refers to the introduction of fresh air into the mine to increase the oxygen concentration to dilute and remove toxic and harmful gases and solid wastes in the mine. The basic tasks of mine ventilation are: supply enough fresh air underground, meet the needs of personnel for oxygen, adjust the underground climate, and create a good working environment. [0003] Mine ventilation equipment is a kind of environmental protection special equipment that works well in the underground. Special equipment for environmental protection refers to the mechanical products, structures and systems manufactured and constructed by production units or constructio...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an underground coal mine ventilation device based on environmental protection to solve the problem that the existing ventilation device directly intercepts the dust through the dust-proof net, and the dust will adhere to the surface of the dust-proof net to block the mesh holes of the dust-proof net, reducing the The ventilation effect of the coal mine underground ventilation device makes the working environment of the workers very bad, reduces the work efficiency of the workers, and seriously affects the health of the workers
