Description

Technical Field

[0001] The utility model relates to the technical field of mine water treatment, in particular to a sand removal device for underground water treatment. Background Art

[0002] Underground water treatment is an indispensable part of the coal mining process. As these water bodies flow through coal mining faces and tunnels, they will be polluted by coal rock powder, organic matter, etc., and generally contain insoluble impurities such as sand and gravel, which will have an adverse impact on the normal production and environment of the mine. The presence of these solid impurities in the water body will wear out water treatment equipment such as water pumps and pipes, shorten their service life, and increase maintenance costs. Sand suspended in the water will make the water quality turbid, affecting the subsequent water treatment effect.

[0003] In mine water treatment, V-type filter is a commonly used water treatment equipment. During the treatment process, poor sealing leads to sand leakage. The sand will flow into the backflow tank and the clear water tank, and then settle to the bottom of the tank. In the actual production process, the water level in the tank has always maintained a critical liquid level. The system runs continuously and cannot be shut down for a long time. The water tank space is limited. Therefore, it is difficult to effectively discharge the accumulated sand at the bottom of the tank without shutting down, which affects the normal operation of the pipeline and equipment and the water treatment efficiency.
