Coal mine underground roadway recyclable automatic mist spraying dust falling device

Abstract

The invention discloses a coal mine underground roadway recyclable automatic mist spraying and dust falling device. The coal mine underground roadway recyclable automatic mist spraying dust falling device comprises a purifying device, wherein a driving device is arranged at the bottom of the purifying device. The amount of water inside the driving device is controlled through a liquid supplementing control device to achieve the purpose of automatically supplementing water for the driving device. By means of the purifying device, dust-containing air in a roadway can enter the interior of the purifying device for mist spraying dust falling, the amount of overflow water mist is reduced, and the problems that the interior of the roadway is muddy and extremely large in humidity are further solved. Dust on a dust filtering net is cleaned through the cooperation of the purifying device, the driving device, the transmission device and an ash scraping device, the dust filtering net is preventedfrom being blocked, and meanwhile, the ash scraping device can fish out dust deposited in the purifying device for draining. The fished deposited dust is discharged through the cooperation of an ashreceiving device, a material blocking device, an ash pushing device and the ash scraping device, and the practicability of the dust falling device is improved.

Description

technical field [0001] The invention relates to the field of spray dust suppression equipment for underground coal mine roadways, and more specifically relates to a circulating automatic spray dust suppression device for underground coal mine roadways. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance from the ground surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine, and a large amount of dust will be generated in the process of underground coal mining. These dusts are scattered in the roadway, which not only affects the coal enterprises Production and development, and will seriously endanger the health and life of workers, so in order to reduce the dust concentration in the roadway, people usually set up a recyclable automati...

AI Technical Summary

Problems solved by technology

[0005] In view of the existence of the existing coal mine underground roadway in the prior art, the recyclable automatic spray dust suppression device is artificially turned on at regular intervals for dust suppression. When the dust concentration is high and the spray dust suppression device is not turned on, the dust suppression cannot be carried out in time, and the dust suppression effect is poor. When the concentration is not high and the spray dust suppression device is turned on, it will cause a huge waste of water resources. While wasting water resources, unnecessary water will also cause the ground in the roadway to be muddy and the humidity in the roadway is too high. The work brings great inconvenience. The purpose of the present invention is to provide a recirculating automatic spray dust suppression device for coal mine underground roadway, which can well solve the problems raised in the background technology.
