A circulating automatic spray dust suppression device for coal mine underground roadway

Abstract

The invention discloses a recirculating automatic spraying and dust suppression device for coal mine underground roadway, which includes a purification device, and a driving device is arranged at the bottom of the purification device; the water quantity inside the driving device is controlled by a liquid replenishment control device, so as to realize automatic cleaning for the driving device. The purpose of replenishing water, through the purification device, the dusty air in the roadway can enter the interior of the purification device for spray dust reduction treatment, reducing the overflow of water mist, and further solving the problem of muddy ground in the roadway and excessive humidity in the roadway The problem is to clean the dust on the filter screen through the cooperation of the purification device, drive device, transmission device, and dust scraping device to avoid the filter screen from being blocked. At the same time, the dust scraping device can remove the dust deposited inside the purification device and drain it. The cooperation of the ash receiving device, the material blocking device, the ash pushing device and the ash scraping device can discharge the deposited dust, which improves the practicability of the dust reducing device.

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.
