Pulverized coal collecting equipment for coal mine site

Abstract

The invention relates to the technical field of mining equipment and discloses pulverized coal collecting equipment for a coal mine site. The collecting equipment comprises a bracket, wherein a purification air box is fixedly mounted at the top end of the bracket; two filtration detection devices are fixedly mounted in an inner cavity of the purification air box and symmetrically distributed; a cleaning device is fixedly mounted at the top end of the purification air box; and a cleaning driving device is fixedly mounted at the top end of the purification air box and located on one side of thecleaning device. Pulverized coal absorbed by filtration screens is increased gradually to compress cleaning detection springs, so that cleaning detection electrical sheets I and cleaning detection electrical sheets II are contacted to turn on an electronic time switch controller; the cleaning driving device is started up to drive the cleaning device for cleaning; functions of automatic detection of a pulverized coal content and automatic cleaning startup after the content reaches a standard are achieved; and the equipment is very conveniently used by a worker.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to coal powder collection equipment for coal mine sites. Background technique [0002] The ambient air of coal mining sites contains a large amount of coal dust, which not only pollutes the air, but also has a serious impact on the respiratory tract of workers, and too much coal dust is prone to explosion when exposed to open flames or high temperatures. The coal powder in the tank is cleaned and collected. [0003] The existing equipment for collecting pulverized coal uses a fan to drive the air flow, and then installs a pulverized coal filter at the air inlet of the fan. When the air flows through the filter, the pulverized coal will be retained on the filter, and then the filter will be cleaned regularly. Cleaning, this method has a good effect on the collection of pulverized coal, but due to the different pulverized coal content in different time periods, the pulverize...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pulverized coal collection equipment for coal mine construction sites, which has the advantages of automatic detection and automatic cleaning of pulverized coal content on the filter screen, convenient post-processing and reuse of pulverized coal, etc., and solves the problems caused by different The pulverized coal content is different at different times, and the pulverized coal accumulation efficiency on the filter screen is different. Therefore, it is difficult to determine the cleaning period of the filter screen. It is necessary to arrange workers to check it frequently, which is extremely inconvenient to use. On the other hand, the collected pulverized coal has no corresponding Measures to deal with the difficult problem of pulverized coal reuse
