Mining pneumatic desilting and sewage pumps - Overview of pneumatic desilting and sewage pumps
Series of mining pneumatic desilting and sewage pumps are driven by compressed air. The main components include the main part, control system and vacuum suction. components etc. The series of mining pneumatic desilting and sewage pumps are suitable for cleaning large amounts of coal slime deposited in underground water tanks in coal mines. The lack of reliable equipment to clean coal slime not only brings a lot of inconvenience to the normal production of coal mines, but also causes a great waste of resources. The sewage pump we developed has realized the efficient and fast processing of the coal slurry and water mixture in the coal mine underground water tank, completely relieved the heavy labor of manually clearing the water tank, and reduced the number of new underground water tanks. It has not only improved the comprehensive economic benefits of the mine water tank clearing. Moreover, it realizes environmental management and protection, saves time and effort, and has wide practicality.
The series of mining pneumatic desilting and sewage pumps are powered by compressed air and are suitable for drainage and sewage treatment at coal mine underground mining working surfaces, roadways, bottom sewage pits, cesspools (wells), water silos, etc. that contain dangerous methane and coal dust. Operation.

Pneumatic dredging and sewage pump for mining-Pneumatic dredging and sewage pump product structure and working principle
The main components of the series of mine pneumatic desilting and sewage pumps include the main part, control system and vacuum suction components, etc. See the structural diagram.
. Main part: It consists of a pump body, a feed pipe, and a discharge pipe. Its job is to suck and discharge materials.
. Control system: The control system mainly uses the organic combination of pneumatic reversing valves, travel switches, shuttle valves, ball valves and time logic reversing valves to achieve the control and switching of the actuator to achieve the unit's working time. Orderly switching between suction and discharge;
. Vacuum suction assembly: The vacuum suction assembly is mainly composed of a Laval nozzle that first shrinks and then expands, a negative pressure chamber and an expansion tube. It is designed based on the principle of Venturi effect and includes air supply port, exhaust port and vacuum port. When the air supply pressure at the air supply port is higher than a certain value, the nozzle emits a supersonic jet. Due to the viscosity of the gas, the high-speed jet sucks away the gas in the negative pressure chamber, causing the chamber to form a higher degree of vacuum. The performance of the vacuum generator is related to many factors such as the small diameter of the nozzle, the shape, diameter and relative position of the contraction and diffusion tubes, and the pressure of the air source. The vacuum suction component communicates with the suction port through the pump body. When the control system switches to control the cylinder operation in cycles, the suction and discharge of the unit can be completed
