The unit is driven by compressed air, and the main components include the main part, the control system and the vacuum suction assembly. This type of air pump is suitable for cleaning up a large number of coal slime deposited in the water silo of the coal mine. Because there is no reliable equipment to clean up the slime, it not only brings a lot of inconvenience to the normal production of the coal mine, but also causes a great waste of resources. The sewage pump developed by us realizes the efficient and fast treatment of coal slime water mixture in coal mine underground sump, completely eliminates the heavy labor of manual cleaning and digging sump, and reduces the number of newly built underground sump, which not only improves the comprehensive economic benefits of mine water warehouse cleaning and digging, but also realizes environmental management and protection, saving time and effort, and has a wide range of practicability.
