Pneumatic dredging device with jet flow and gas lift functions
The invention relates to a pneumatic desilting device with jet flow and air lift effects. The pneumatic desilting device is mainly provided with a pneumatic pump, an air compressor, an air lift device and a jet flow device. The device is characterized in that the gas lifting device and the jet device are respectively connected with an exhaust pipe of the pneumatic pump through pipelines; when the pneumatic pump exhausts air, the exhausted air enters the jet device and the air lift device, underwater sediment is broken and scattered under the jet action of high-pressure air of the jet device, part of the sediment is discharged out of a water body under the air lift action of the air lift device, and the other part of the sediment enters the pneumatic pump along with the discharge of high-pressure air in the pneumatic pump under the action of environmental water pressure. After the pneumatic pump is filled with the silt, the air compressor injects high-pressure gas into the pneumatic pump, and the high-pressure gas pushes the silt in the pneumatic pump to be discharged through the pneumatic pump sludge discharging pipe. The pneumatic desilting device with the jet flow and gas lift effects fully utilizes the exhaust energy of the pneumatic pump, and is simple in structure, good in desilting effect and high in energy utilization rate.
本发明涉及一种带有射流及气举作用的气力清淤装置，主要设有气力泵、空压机、气举装置、射流装置；其特征在于：气举装置、射流装置通过管路分别与气力泵排气管相连；气力泵排气时，排气分别进入射流装置和气举装置，水底泥沙在射流装置的高压气体射流作用下破碎冲散，部分泥沙在气举装置的气举作用下排出水体，另一部分泥沙随着气力泵内高压气体的排出在环境水压的作用下进入气力泵；泥沙充满气力泵后，空压机向气力泵中注入高压气体，高压气体推动气力泵内的泥沙由气力泵排泥管排出。本发明带有射流及气举作用的气力清淤装置充分利用了气力泵排气能量，结构简单，清淤效果好，能源利用率高。
