Description

Ship rust removal high pressure cleaning system

technical field

The utility model relates to metal rust removal, in particular to a ship rust removal high-pressure cleaning system.

Background technique

Ship derusting is especially important in the ship repair industry. The main methods are manual derusting, mechanical derusting, chemical derusting and ultra-high pressure water derusting. Manual rust removal has limitations, because of its low rust removal efficiency, it is mainly used in the repair of local defects, as well as in difficult areas such as small cabins, corners and edges on the reverse side of profiled steel; mechanical rust removal cannot remove scale, and the surface roughness is small. High-quality surface treatment quality cannot be achieved; chemical rust removal can only be performed in the workshop, and the best rust removal method is ultra-high pressure pure water jet rust removal.

At present, the Chinese patent with the authorized announcement number CN205817538U in the existing patent discloses a self-propelled ship derusting machine, including a motor, a grinding tool and a frame connected to the motor through a transmission mechanism, and the motor and the grinding tool are arranged on the frame The grinding tool is set on the upper end of the frame, the motor is set on the lower part of the frame, and the transmission mechanism connects the motor and the grinding tool, so that the waste after grinding can be collected effectively, which greatly reduces the cleaning burden after grinding.

Most of the descaling machines in the prior art spray cooling water at the same time to flush the derusted dirt in time when derusting. However, the cooling water is usually directly used by extracting seawater, and the plankton in the seawater is easy to be extracted. Affect the stability of the rust removal process.

By adopting the above technical scheme, the water pressure of the high-pressure spray gun is relatively high, which can better derust the ship; when the cleaner cleans the ship, due to the high water pressure, a large amount of water will react on the cleaner's body On the body, the water retaining ring plate plays a better blocking role, preventing a large amount of water from spraying on the cleaning workers.

The utility model is further set as: the water retaining ring plate is a transparent acrylic plate.

By adopting the above-mentioned technical solution, the transparent acrylic board is light and transparent, and can block the reactive water without affecting the sight of the cleaning workers, which significantly improves the convenience of the derusting process.

In summary, the utility model has the following beneficial effects:

1. The utility model provides a high-pressure cleaning system for derusting ships, which has a good filtering effect on seawater and improves the cleanliness of water used in the derusting process;
