Underground gangue crushing equipment with dedusting function

Abstract

The invention provides underground gangue crushing equipment with a dedusting function. The underground gangue crushing equipment with the dedusting function comprises a closed shell, a feeding device, a crushing unit, a dedusting device, a wet type mist spraying dedusting system and a transfer machine. The feeding device is located at the top of the closed shell and connected with the crushing unit. The crushing unit comprises a crushing machine and an explosion-proof transmission motor, wherein the crushing machine and the explosion-proof transmission motor are connected through a belt and both fixed to the bottom of the closed shell. The dedusting device is fixed to the top of the closed shell and located at the right side of a feed hopper and is open leftwards. The wet type mist spraying dedusting device comprises a high-pressure water pipe and atomization nozzles which are installed on the high-pressure water pipe and located around an outlet in the bottom of the crushing machine. The transfer machine is located below the right portion of the closed shell. The underground gangue crushing equipment with the dedusting function is simple in structure, convenient to operate, low in manufacturing cost and high in practicability. The equipment both has the gangue crushing function and the dedusting function, the working environment is effectively purified, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the field of coal mine machinery, in particular to underground gangue crushing equipment with a dust removal function. Background technique [0002] As the main energy source in our country, coal plays an extremely important role in the social and economic development. Coal gangue is solid waste discharged during the process of coal excavation, mining and washing, and has long been regarded as a harmful substance by the coal industry. The accumulated coal gangue in China has reached more than 1 billion tons, and 100 million tons of coal gangue will be discharged every year. The underground space of coal mines is small. During the crushing and reloading of coal gangue, a large amount of dust will be generated in the confined space. Coal mine dust is one of the five major disasters in coal mines. Therefore, it is crucial to control the generated dust during the crushing process of gangue The important link is closely related to...

AI Technical Summary

Problems solved by technology

Ventilation and dust removal are the main means to control dust hazards, but in the process of ventilation and dust removal, the required air volume is large, the work site is seriously polluted, the dust spreads with the wind in the roadway, and the working environment is poor, which seriously affects daily safety production and Workers' health

This problem can be effectively solved by treating the dust generated by gangue crushing from the source of dust production, but currently there are few professional equipment for dust sources, and the development of underground gangue crushing equipment with dust removal function is of great significance to improve the safety of mine production.
