Metal bent pipe rust removal device and method thereof

Abstract

The invention discloses a metal bent pipe rust removal device and method thereof. The metal bent pipe rust removal device comprises a bottom plate, a metal bent pipe, a guide hose pipe and a hopper, wherein the metal bent pipe is a hollow pipe; one end of the metal bent pipe is a feeding opening end; the other end of the metal bent pipe is a discharging opening end; the guide hose pipe is locatedin the metal bent pipe and is consistent with the bent shape of the metal bent pipe; a guide block capable of moving along a length direction of the guide hose pipe is arranged on the guide hose pipe;the hopper comprises a feeding hopper and a discharging hopper; the discharging hopper corresponds to the position of the feeding opening end of the metal bent pipe; a high-pressure nozzle is arranged in the feeding hopper; the tail end of the high-pressure nozzle is connected with an external air supply device. The rust removal device and the rust removal method are simple to operate, are capable of carrying out the operation of removing the rust on the inner wall of the metal bent pipe by simultaneously using two physical and chemical manners, are simple to implement and excellent in rust removal effect; the influence on the environment is reduced to the minimum.

Description

technical field [0001] The invention belongs to the technical field of rust removal and polishing, and in particular relates to a metal elbow rust removal device and method. Background technique [0002] With the development of industrialization, the development of technical fields such as construction industry and pipeline transportation has advanced by leaps and bounds. In these application fields, a large number of metal elbows of different shapes are involved and used. [0003] The more important part in the processing of metal elbows is rust removal. As we all know, the rust removal of the outer surface of metal elbows is relatively simple, but the internal rust removal is more complicated. Due to the particularity of metal elbows compared with metal straight pipes, it is difficult to use The inner wall is derusted mechanically, so the inner wall can only be cleaned chemically, that is, the inside of the metal pipe is cleaned with acid or lye, but this method is easy to...

[0003] The more important part in the processing of metal elbows is rust removal. As we all know, the rust removal of the outer surface of metal elbows is relatively simple, but the internal rust removal is more complicated. Due to the particularity of metal elbows compared with metal straight pipes, it is difficult to use The inner wall is derusted mechanically, so the inner wall can only be cleaned chemically, that is, the inside of the metal pipe is cleaned with acid or lye, but this method is easy to cause damage to the metal elbow and will corrode Metal elbows, while causing a certain impact on the ecological environment
