High-pressure water rust removal device for inner wall and outer wall of metal bent pipe

Abstract

The invention relates to the technical field of metal rust removal, in particular to a high-pressure water rust removal device for the inner wall and the outer wall of a metal bent pipe. The device comprises a shell internally provided with a cleaning cavity, and the bottom of the cleaning cavity is provided with an overturning clamping device used for clamping the bent pipe through a lifting push rod. The device has the beneficial effects that the device can adapt to metal bent pipes with different bending angles so that the inner walls and the outer walls of the metal bent pipes can be subjected to rust removal without dead angles, metal straight pipes and metal rods can also be subjected to rust removal, the rust removal universality is better, and the rust removal process of the device is in a closed space; and pollutants such as waste water generated in the rust removal process are more conveniently collected, so that pollution is smaller, the occupied area needed by operation can be better reduced, and the device not only supports workers to manually input an instruction to conduct cleaning operation, but also conducts automatic cleaning operation in an early programming mode when continuous rust removal operation is conducted on the bent pipes of the same model so that the operation intensity of workers can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of metal rust removal, in particular to a high-pressure water rust removal device for the inner and outer walls of a metal elbow. Background technique [0002] After long-term use of metal pipe fittings, due to the lack of protective paint layer on the metal wall surface or the peeling off of the protective paint layer, the metal wall surface is in contact with air or other corrosive substances for a long time, which will cause corrosion on the surface of the metal pipe fittings. If the rust is allowed to continue, the metal pipe fittings will gradually reduce their structural strength and lose their function. Therefore, regular inspection and maintenance of the metal pipe fittings is required to remove the rust layer on the surface of the metal pipe fittings and then repaint the anti-rust paint layer to prevent corrosion. continue. Existing methods for derusting the surface of metal pipe fittings include g...
