HK1237194A2 - Underwater cavitation jet cleaning system - Google Patents

Abstract

The underwater air jet cleaning system is equipped with an automatic metering feeder for cleaning liquid, which combines cavitation jet technology with the improvement of cleaning liquid. This not only increases the increase of bubbles during the jet, but also benefits the removal of ship dirt.The vortex section of the nozzle is set as a spiral channel, and the vortex section gradually decreases from the inlet to the outlet direction, further increasing the velocity of the fluid. Due to the different volume sizes of the inner chamber of the gun barrel, the fluid flows in a pulsed manner when passing through the tube, resulting in the final fluid ejected from the cleaning gun nozzle in a pulsed manner, effectively improving the cavitation rate and increasing the generation of cavitation nuclei.The hollow shaft of the cleaning disc is equipped with a guide channel, and the wall of the guide channel is provided with multiple arc-shaped strips. The hollow shaft sprays fluid downwards, and the fluid also exerts a pushing force on the cleaning disc, which is beneficial for the cleaning disc to float in water.
