It has a large conveying capacity and a high lifting height. The TL series pneumatic lift pump is a device for pneumatic vertical conveying and lifting materials. It is mainly used for conveying cement, coal powder and other powder materials. The equipment has a simple structure, convenient and reliable operation, no dust, small wear of parts and easy maintenance. Chinese Patent No.: CN202121394677.X discloses a high-efficiency pneumatic lift pump, which relates to the field of pneumatic lift pumps, including a pneumatic lift pump body, a discharge pipe is provided on the pneumatic lift pump body, a telescopic hose is fixedly installed on the discharge pipe, a mounting plate is provided on one side of the pneumatic lift pump body, a motor is fixedly installed on the mounting plate, a motor shaft is fixedly installed on the output end of the motor through a coupling, a turntable is fixedly installed on the motor shaft, a driving rod is rotatably installed on the turntable, a driven rod is rotatably installed on the driving rod, and a driven shaft is fixedly installed on the other end of the driven rod. The utility model, through the provision of a clearing rod, when the air lift pump body is used to transport solid and liquid materials, the clearing rod is moved in the discharge pipe, thereby clearing the solid and liquid materials blocked in the pipe, avoiding the blockage of the pipe affecting the normal use of the air lift pump, or even damaging the air lift pump body, thereby ensuring the normal use of the air lift pump.

[0003] Based on the above, the inventors discovered the following problems: the overall design of the above patent is novel and the structure is simple. The design at that time pointed out the cleaning of the accumulation in the pipeline, and solid and liquid materials would remain on the inner wall of the pneumatic lift pump.
