Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mining equipment, especially relates to a movable vertical dry-wet separation device for mine. BACKGROUND

[0002] At present, in the process of coal mine underground production, raw coal is transported from the mining face to the ground coal storage bin, which needs to be transported by transportation lifting equipment. In the transportation process, a belt conveyor or a bucket elevator is mostly used. The belt conveyor is a necessary transportation equipment. In the conveying process, it is inevitable that there will be raw coal thrown down and coal slime adhered to the belt cleaned by the belt sweeper. These coal slime and raw coal are washed by water and collected into a sedimentation tank or a collection tank in the transportation roadway. After a long time of collection, the collection tank is filled. At this time, the solid matter in the sedimentation tank needs to be cleaned, but the sedimentation tank is a mixture of coal and water. First, the coal water on the solid matter is pumped to another place by a sludge pump for further treatment. The remaining material is in a porridge-like state and has lumpy raw coal that needs to be cleaned manually. Workers use a shovel to dig the porridge-like material into the ground next to the sedimentation tank, one shovel at a time. The cleaned material is then transported to a mine car or even piled up on the ground to dry naturally before being transported away. Since the sedimentation tank is about 1-2 meters deep, 5-20 meters long, and 1-2 meters wide, there are safety hazards in cleaning the sedimentation tank from the inside to the ground, and the labor intensity is high and the efficiency is low.

[0003] A mine slurry suction device is disclosed in Chinese Patent No. CN214497633U. The technical solution includes a box body, a rotating shaft rotatably connected inside the box body, a ring groove provided on the rotating shaft, a spiral fan blade fixedly connected to the outside of the rotating shaft, the spiral fan blade being in contact with the inner surface of the box body, a box cover threadedly connected to the outside of the box body, a shaft tail fixing seat fixedly connected to the inside of the box cover, a rotating shaft rotatably connected inside the shaft tail fixing seat, and a lifting and squeezing motor seat welded to one end of the box body away from the box cover. This solution is a horizontal fixed structure that solves the problem of rapid dry-wet separation of slurry. However, when facing larger lumpy raw coal in the sedimentation tank, it is difficult for the slurry suction pump to extract it, and the suction pipe of the slurry suction pump is not easy to move, making it difficult to extract the material in the sedimentation tank completely.
