[0038] The liquid storage tank 9 is mainly used for storing the cleaning liquid.
[0039] The pneumatic pump 10 is mainly used for quickly pumping the cleaning liquid in the liquid storage tank 9 into the equipment pipeline 300 by using compressed air as power.
[0040] The liquid receiving tray 11 is mainly used for temporarily storing the cleaning liquid.

Then the operator starts the pipeline automatic cleaning device, first opens the second electromagnetic valve 2, the fourth electromagnetic valve 4 and the sixth electromagnetic valve 6 at the same time, and closes other electromagnetic valves, and the compressed air used by the positive pressure air source 200 starts to drive the pneumatic pump 10 to work, the pneumatic pump 10 pumps the cleaning liquid out of the liquid storage tank, then pumps it into the equipment pipeline 300, and finally flows into the liquid receiving tray 11 for buffering.
