An upper part of the bubble generator 7 is connected with a water delivery pipe 9 and an air pump 8. The water delivery pipe 9 inputs high-pressure water into the bubble generator 7, and the air pump 8 inputs high-pressure air into the bubble generator 7. A large amount of micron-level bubble water is generated in the bubble generator 7, and then the bubble water is sprayed out from the nozzles 13 to clean the papermaking wire 1 360°. The principle of bubble cleaning is that the high-energy impact and shear force generated by the rupture of bubbles can efficiently peel off dirt, especially effective for stubborn dirt, and will not cause mechanical damage or chemical corrosion to the papermaking wire 1, extending the service life of the screen. Bubble cleaning usually only requires a small amount of water and gas, with low resource consumption, does not require the use of a large amount of chemical cleaners, reduces the use and emission of chemicals, and has good environmental protection effects; a water recovery mechanism, the water recovery mechanism includes a water collecting tank 16 located below the papermaking wire 1, the water collecting tank 16 is fixedly arranged at the lower part of the bracket 2, a water return pipe 14 is arranged at the lower part of the water collecting tank 16, and a water return pump 18 and a filter 15 are arranged on the water return pipe 14.
