Problems solved by technology

In the prior art, the cleaning gun only cleans all the rust layer and primer in the rust removal area uniformly according to the same pressure. When encountering an area with less rust layer, it is easy to destroy the good paint part of the outer layer area. Causes an increase in the cost of the secondary coating; furthermore, when the primer is applied for the second time, the primer cannot be applied on the outermost layer of paint, otherwise the coating adhesion will be too poor

Abstract

The invention discloses a water jet rust removal cleaning gun capable of forming a gradient coating. The cleaning gun comprises a cleaning gun body, corresponding nozzle holes are formed in a cross-shaped spray rod on the cleaning gun body, nozzles on the outermost side of the cross-shaped spray rod are arranged outwards by 15-45 degrees in the original direction, the rest nozzles are vertically and eccentrically arranged, high-pressure water enters the cross-shaped spray rod through a rotating body and is sprayed by the nozzles to achieve the purpose of cleaning and rust removal; the nozzles are asymmetrically and eccentrically arranged to drive the cross-shaped spray rod to rotate automatically, at the moment, the jet flow vertical impact force of the middle rust removal area of the cleaning gun body is maximum, rust removal of the middle area is complete, the cleaning gun body can drive the cross-shaped spray rod to rotate automatically, extra work does not need to be applied, the nozzles in the cross-shaped spray rod are vertically installed, and the nozzles on the outermost layer are installed outwards, so that the impact force applied to the center and the impact force applied to the outer layer are different, a certain pressure difference is formed, it can be guaranteed that rust in the middle area can be completely removed, it can also be guaranteed that original good primer in the outer layer area is not damaged, the jet flow tangential force can be enlarged, and the jet flow cleaning area can be increased.

Description

technical field [0001] The invention relates to the technical field of ship cleaning and rust removal, in particular to a water jet rust removal cleaning gun capable of forming a slope coating. Background technique [0002] Ships and marine engineering equipment have been serving in a high-salt, oxygen-rich corrosive environment for a long time. The corrosion problem has always been an important factor affecting the life of the ship. Protective coating is an important protective measure to prevent steel corrosion control. Ship derusting is the first step in the coating construction of ship repairing. Only good pre-treatment of the hull surface can make the coating achieve the expected protective effect. In the prior art, the cleaning gun only cleans all the rust layer and primer in the rust removal area uniformly according to the same pressure. When encountering an area with less rust layer, it is easy to destroy the good paint part of the outer layer area. The cost of seco...
