Underground coal mine drainage ditch sludge cleaning device

Abstract

The invention discloses an underground coal mine drainage ditch sludge cleaning device, belongs to the technical field of coal mining, solves the problem that existing underground coal mine drainage ditch sludge cleaning equipment is poor in sludge cleaning efficiency, the device is technically characterized in that the device comprises a device body, and universal wheels enable the device body to be convenient to move; a second electric telescopic rod controls the universal wheels to ascend and descend, a shovel plate pushes sludge into the device body, the motor is started, a conveying shaft is driven to rotate, a dredging shovel rotates to conduct dredging, a first auger blade conveys the sludge to a discharging pipe to be discharged, a coarse filter screen, a fine filter screen and a second water filter screen conduct layer-by-layer filtering, water is stored in a water storage cavity, and stirring blades conduct stirring and scattering. The second auger blade conveys materials, the sludge pump is started, sludge is pumped into a sludge storage box, a water pump is started, water is sprayed out of water spraying equipment, the pitching angle is conveniently adjusted through the first electric telescopic rod, garbage, pebbles and the like are conveniently cleaned through a slag discharging door, and the device has the advantages that the sludge cleaning efficiency is high, water resources are recycled, and the height is conveniently adjusted.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a sludge cleaning device for underground drains in coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. Coal mines include large areas above and below ground and associated facilities. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadway...

Problems solved by technology

[0003] In the underground drainage ditch of coal mine, a large amount of sludge will be generated during the mining process, which will easily block the drainage ditch for a long time, which is not conducive to drainage. The traditional sludge cleaning equipment is simply extracted by a sludge pump. The sludge contains various All kinds of garbage can easily block the mud pump, which greatly reduces the efficiency of sludge cleaning. At the same time, the existing equipment cannot isolate and collect garbage and stones, which cannot meet the needs of actual use. It can be seen from the above that the existing The sludge cleaning equipment for underground drainage ditches in coal mines has the disadvantage of poor sludge cleaning efficiency, so it is difficult to be popularized and applied
