Background
The prior pneumatic equipment for dredging comprises two types, namely a pneumatic pump (a horse pump) which takes compressed air as a piston to pump out slurry entering a pump body under the action of water level differential pressure; one is a gas lift pump (air lift pump) which injects compressed air into a lifting pipe and lifts sludge from the water bottom to the water surface by using the pressure difference caused by the density difference of the liquid inside and outside the lifting pipe. The two pneumatic dredging devices have the characteristics of simple structure, no easily-damaged parts, and safe and reliable work, do not disturb a clay layer in the dredging working process, and are particularly suitable for environment-friendly dredging and dredging which can not damage water bodies such as rivers, lakes, reservoirs and the like with existing water quality.

Although the pneumatic pump has the advantages of simple structure and no pollution to water during dredging, the high-pressure air in the pump body is directly discharged into the atmosphere, so that effective work is not generated, energy waste is caused, the energy utilization rate is low, and the energy consumption cost is high; especially under the working condition that the pneumatic pump is used for conveying slurry in a long-distance pipeline, the pressure of high-pressure air in the pump body is far higher than the ambient water pressure, and the high-pressure air is directly discharged into the atmosphere, so that the energy is greatly wasted, and the running cost of the pneumatic pump is greatly increased; and because the pneumatic pump presses the silt into the pump body by the action of water pressure, the underwater hard clay and gravel are not easy to enter the pump body by the action of water pressure, so that the pneumatic pump is only suitable for dredging engineering of fluid silt, but is difficult to be competent for the commonly existing gravel dredging work in the dredging and governing engineering of rivers, lakes and reservoirs.
