Detailed Description

The following detailed description of the embodiments of the invention, however, is intended to cover by the appended claims a number of different forms which may be practiced.

As an aspect of the utility model, a single cavity multislot formula industrial cleaning equipment's string liquid blowback system of preventing is provided, include: switching valve 1 and return water pump 2, the liquid outlet of single cavity multislot formula industrial cleaning equipment's working chamber 3 with return water pump 2 is connected, return water pump 2's import through a plurality of parallelly connected pneumatic control valves 4 that set up with single cavity multislot formula industrial cleaning equipment's a plurality of basins 5 one-to-one are connected, return water pump 2's main return water pipeline 6 respectively with a plurality of basins 5 are connected, just main return water pipeline 6 is connected with compressed air inlet 8 through switching valve 1.

The compressed air inlet 8 is used for accessing external compressed air to blow back residual liquid in the whole pipeline, and the high-pressure gas blows back residual cleaning liquid in the return water main pipeline 6 and the pump head of the return water pump 2 into the corresponding water tank 5; the switch valve 1 has the function of cutting off the air source, and prevents the phenomenon of backflow of cleaning fluid caused by the disconnection of compressed air; the pneumatic control valve 4 controls the opening and closing of the pipeline, so that the cleaning liquid returns to the correct water tank.

Preferably, an external thread threaded pipe 9 is arranged at the end face of the main water return pipeline 6, and the switch valve 1 is connected with the external thread threaded pipe 9.

Preferably, the compressed air inlet 8 is a pagoda joint. Preferably, the compressed air inlet 8 is connected to an air compressor.
