Abstract

The invention belongs to the technical field of rust removing device, in particular to a cavitation rust removing device, which comprises a hydraulic system, an air pressure system and a cavitation generator, wherein both the hydraulic system and the air pressure system are communicated with the cavitation generator, and high-pressure liquid can be provided through the hydraulic system, by means of the air pressure system, high-pressure gas can be provided, the high-pressure liquid can be mixed with the high-pressure gas through the capitations generator, the cavity generator is communicated with a damping nozzle, and the mixture can be ejected through the damping nozzle.The cavitation generation is jointly controlled by a hydraulic system and a pneumatic system, a special cavitation generator is utilized, the convection field is analyzed to generate cavitation bubbles, the bombardment action of the shock wave formed by the bubble burst on the metal surface is generated, the purpose ofpeeling and cleaning the rust corrosion layer on the metal surface can be achieved.This method of removing rust by the principle of cavitationutilizes the inevitable cavitation phenomenon in the hydraulic system, so that the cavitation phenomenon can be changed into profit, and the purpose of cleaning is achieved.

Description

technical field [0001] The invention belongs to the technical field of derusting devices, and in particular relates to a cavitation derusting device. Background technique [0002] In the field of steel production and protection, especially in the field of steel protection, it is often necessary to remove rust on the surface of steel. At present, the derusting technology of steel surface is mainly divided into two categories, namely physical derusting and chemical derusting. Physical derusting is mainly divided into: manual derusting, mechanical grinding and derusting, flame derusting, electric spark derusting; manual derusting is time-consuming and labor-intensive, mechanical grinding and derusting is easy to cause unnecessary wear on the steel surface, flame derusting And electric spark rust removal consumes a lot of energy and has low safety. Chemical derusting is mainly to remove the rust on the steel surface through chemical reaction, and the reaction is difficult to c...
