Under normal working conditions, cleaning liquid enters from the water inlet 391, gas enters from the air inlet 392, and when a workpiece is cleaned, the cleaning liquid is sprayed from the liquid spray header 393 for cleaning, and the gas spray header 394 is matched for gas spray cleaning, so that scrap iron impurities on the volute workpiece can be effectively cleaned, liquid can be blown off, and the surface of the workpiece is ensured not to be excessively wet. When the gas/liquid purging structure 39 moves along the second sliding rail 37, a limiting piece 371 is further arranged at the tail end of the second sliding rail 37, so that the gas/liquid purging structure 39 is ensured not to slide out of the rail in the moving process. The gas/liquid purging structure further comprises a gas-liquid branching device for dividing the cleaning liquid and the gas path into six paths respectively, wherein the liquid path and the gas path can be independently controlled to be on-off. When the workpiece just enters the cleaning chamber, the spray head sprays cleaning liquid to clean scrap iron of the workpiece, and after the liquid cleaning is finished, the spray head sprays gas to blow off floating water on the surface of the workpiece. The spray header translation cylinder can control the spray header to move back and forth, so that the phenomenon that the workpiece cannot be sprayed in some places is avoided.
