The setting of the device table makes the whole device more complete, and it is also convenient to collect waste water and fasteners at the collection port.

Preferably, there are four connecting pipes, and six nozzles are equidistantly arranged on each connecting pipe, and the four groups of nozzles are evenly distributed on the nozzle holder along the circumferential direction of the nozzle holder. This setting can ensure sufficient rust removal.

As an improvement, a sealing strip is provided at the contact portion between the upper protective cover and the lower protective cover. Ensure that the protective cover can better prevent the water in the cleaning drum from splashing out.

Preferably, the rotation speed of the cleaning drum is 60-600 rotations per minute. The rotation speed within this range ensures sufficient rust removal, and at the same time avoids damage to fasteners caused by collisions with each other due to excessive rotation speed.

As an improvement, a steel grit layer is provided on the inner wall of the cleaning drum. When the fastener is derusted in the cleaning drum, it will rub against the steel grit layer, which has a better derusting effect.

Compared with the prior art, the utility model has the advantages of: using the principle that the ultra-high pressure water jet cleaning mechanism can effectively remove rust, placing the fasteners in the cleaning drum for rust removal can ensure more efficient rust removal; The rust method does not involve chemical methods, and will not produce waste liquid that is harmful to the environment. It is an environmentally friendly and pollution-free rust removal device.
