Technical Field

The invention relates to a rust removing device, in particular to an automatic rust removing device for a ship.

Background

After a ship runs or navigates for a certain period of time, the surface of the hull plate or the hull structure can gradually form a relatively serious corrosion layer in the marine environment, and if the corrosion layer is not processed in time, hidden dangers can be brought to the structural strength of the ship and the navigation safety of the ship. Thus, ships need to go to a shipyard periodically for rust removal and repainting operations.

The sand blasting rust removal is a ship rust removal technology commonly used by ship repair enterprises at present, is widely used in the industry for many years, and is a mature ship rust removal technology.
