Water mist sand blasting derusting device for ships

Abstract

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.

Description

technical field [0001] The invention relates to the field of ship rust removal, in particular to a ship water mist sandblasting rust removal device. Background technique [0002] Water mist sandblasting is powered by compressed air to form a high-speed jet beam to spray materials (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the surface of the workpiece When the appearance or shape of the surface changes, due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece can be improved, thus improving the fatigue resistance of the workpiece It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also beneficial to the leveling and decoration of the coating.

AI Technical Summary

Problems solved by technology

[0003] On the hull, water mist sandblasting is often used for rust removal. The traditional water mist sandblasting will be affected by the wind, affecting the sandblasting effect, and it is not easy to control the intensity of sandblasting. If you want to increase The intensity of sandblasting cannot be controlled by traditional water mist sandblasting machines, and when performing water mist sandblasting, sandblasting with different intensities is required according to different rust conditions. The existing ones are not easy to control, so it is urgently needed Design ship water mist sandblasting derusting device to solve the deficiencies of the existing technology
