Description

Technical Field

[0001] The present invention belongs to the technical field of mining equipment, and particularly relates to a movable vertical dry-wet separation device for mines. Background Art

[0002] At present, during the production process in coal mines, raw coal is transported from the mining face to the ground coal storage bin through transportation and lifting equipment. During the transportation process, belt conveyors or bucket elevators are mostly used. Belt conveyors are essential transportation equipment. Inevitably, there are scattered raw coal and coal slime adhered to the belt cleaned by the belt cleaner during the transportation of the belt conveyor. These coal slime and raw coal are washed with water and collected in sedimentation tanks or collection tanks in the transportation roadway. After long-term collection, the collection tank is filled. At this time, it is necessary to clean the solids in the sedimentation tank. However, the sedimentation tank is a mixture of coal and water. First, the coal water on top of the solids is pumped to another place for further treatment by a sludge pump. The remaining material is in a porridge-like state and there are lumps of raw coal that need to be manually cleaned. Workers use shovels to dig the thin paste-like material shovel by shovel to the ground beside the sedimentation tank, and then manually clean it into the mine car and transport it away. Some are even piled up on the ground and air-dried naturally before being transported away. Since the sedimentation tank is about 1 - 2 meters deep, about 5 - 20 meters long, and about 1 - 2 meters wide, manually cleaning from the sedimentation tank to the ground beside the sedimentation tank poses a safety hazard, and the labor intensity is high and the efficiency is low.

[0003] Chinese Patent with publication number CN214497633U discloses a mine mud suction device. Its technical solution includes a box body. A rotating shaft is rotatably connected inside the box body. An annular groove is provided on the rotating shaft. A spiral fan blade is fixedly connected to the outside of the rotating shaft. The spiral fan blade is in contact connection with the inner surface of the box body. The outside of the box body is threadedly connected with a box cover. An end shaft fixing seat is fixedly connected to the inner side of the box cover. A rotating shaft is rotatably connected inside the end shaft fixing seat. A lifting and squeezing motor seat is welded to one end of the box body away from the box cover. This solution is a horizontal fixed structure, which solves the problem of rapid dry-wet separation of mud. However, in the face of large lumps of raw coal in the sedimentation tank, it is difficult for the mud suction pump to extract them, and the suction pipe of the mud suction pump is not easy to move, making it difficult to extract all the materials in the sedimentation tank.
