In order to solve the problem that the
sand blasting force is not easy to control in the prior art, the invention discloses a water mist
sand blasting derusting device for ships, which comprises a mounting rack, a connecting frame is fixedly mounted at the right end of the mounting rack, a
handle is fixedly mounted on the right end surface of the connecting frame, a connecting rack is fixedly connected to the right side in the mounting rack, a motor is fixedly mounted on the rear surface of the connecting rack, a first gear is mounted at the front end of the motor, a water mist
sand blasting machine is fixedly mounted on the left side of the surface of the mounting rack, a spray
pipe is mounted on the left side of the water mist sand
blasting machine, a
lantern ring is fixedly connected to the left end of the spray
pipe, a rotating shaft is sleeved with the
lantern ring, the front end of the surface of the rotating shaft is fixedly sleeved with a second gear, a chain is connected between the first gear and the second gear, and the surface of the rotating shaft is fixedly sleeved with a
rotating disc. The
rotating disc can be driven by the motor to rotate, the water mist sand blasting force can be enhanced through
centrifugal force, and therefore derusting through water mist sand blasting is effectively achieved.
