Series of pneumatic dredging and sewage pumps for mines
Overview
Intelligent, high-efficiency and energy-saving pneumatic dredging and sewage pumps for mines It is a series of sewage equipment products with independent innovation, independent research and development, and independent intellectual property rights of our company. The technology is at the international leading level.
This desilting and sewage pump is powered by compressed air and is suitable for drainage and sewage operations such as underground mining working surfaces, roadways, bottom sewage pits, cesspools (wells), and water silos in coal mines that contain the risk of methane and coal dust explosions.
The dredging and sewage pump we developed realizes efficient and fast processing of coal slime and water mixtures in underground coal mine water silos, completely relieving the heavy labor of manually digging water silos and reducing the number of new underground water silos. It not only improves mine water The comprehensive economic benefits of warehouse clearing and excavation realize environmental management and protection, save time and effort, and are widely practical.

Product structure and working principle
The main components of this desilting and sewage pump include the main body, control system and vacuum suction components.
. 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 contracts 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 minimum 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 is connected to the suction port through the pump body. When the control system switches the control cylinder in cycles, the suction and discharge process of the unit can be completed.
