[0033] The working principle and use process of this utility model:

[0034] When in use, the mining sewage in the mine is sent into the water tank 1 through the drainage system inside the mine. The upper side of the water tank 1 is lower than the bottom surface of the buffer tank 2. The pump 4 is started, and the pump 4 draws water from the sedimentation pipe 6 through the suction pipe 5. The sedimentation pipe 6 draws water from the water tank 1 under the suction force of the suction pipe 5. The sewage passes through the filter head 62 on the lower side of the sedimentation pipe 6 and enters the pipe body 61. The coarse mesh plate 63 will first filter out obvious floating objects in the sewage. When the sewage moves upward through the pipe body 61, it is only necessary to control the power of the pump 10 to make the rising speed of the sewage less than the settling speed of the sediment in the still water, that is, the sand and gravel sediment can be relatively close to the sewage. The sewage continues to move upward, and when passing through the fine mesh plate 64, it can further filter out smaller sand and gravel sediments through the fine mesh plate 64 and the ceramic balls 65. Then, the sewage containing fine sediments enters the pump 1 4 through the suction pipe 5, and then enters the buffer tank 2. The buffer tank 2 has a certain sedimentation effect on the sediment. Then, the pump 2 10 is started, and the pump 2 10 sucks out the sewage through the suction pipe 11 and discharges it from the output end. It is initially filtered through the coarse mesh plate 63 of the sedimentation pipe 6, and then the sand and gravel are separated when it rises in the pipe body 61. , and then further filtered through the fine mesh plate 64 and the ceramic ball 65, and finally precipitated through the buffer tank 2, which can separate most of the sand and gravel sediments in the mine sewage, so that when the sewage is sucked and discharged, a large amount of sediment is prevented from entering the pipeline, thereby preventing a large amount of sediment from blocking the pipeline, reducing the frequency of pipeline cleaning, and promoting the stability of mine drainage.
