The utility model discloses a derusting device for
metal product processing, which comprises a derusting
pool, the bottom surface of the derusting
pool is fixedly connected with a support shell, the support shell is internally provided with a filter box, the upper surface of the filter box is provided with a sealing cover through screws, the filter box is internally provided with a filter plate, and the filter plate is fixedly connected with the support shell. And the bottom face of the
rust removal
pool fixedly communicates with a filter
pipe, the end, away from the
rust removal pool, of the filter
pipe penetrates through the supporting shell and communicates with the left side face of a filter box, the right side face of the filter box fixedly communicates with a
circulating pump, and the output end of the
circulating pump fixedly communicates with a
backflow pipe. According to the device, a
circulating pump is matched with a
backflow pipe to feed filtered
rust removal liquid into a rust removal pool, a fixing pipe and a spray head are arranged in the rust removal pool, the rust removal liquid is sprayed out through the
backflow pressure of the backflow pipe, then the fluidity of the rust removal liquid can be improved, meanwhile, an
ultrasonic generator installed on the rust removal pool is matched with ultrasonic rust removal, and the rust removal efficiency is improved. And therefore, the rust removal effect of the
metal product can be improved.
