Rust removal device and method for inner wall of metal pipe

Abstract

The invention discloses a rust removal device and method for the inner wall of a metal pipe. The device comprises a pipe body and a rotation ring; metal particles are placed in a cavity of the pipe body, the rotation ring is located on the outer surface of the pipe body and connected with the pipe body through a thread track, multiple magnets electrically connected with the exterior are arranged in the rotation ring, and the rotation ring can rotate relative to the pipe body and can move in the length direction of the thread track in the rotation process. The device is easy to operate, the inner wall of the metal pipe can be subjected to dust removal operation, the dust removal effect is guaranteed, and the portions, without rusty layers, of the metal pipe cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of rust removal and polishing, and in particular relates to a rust removal device and method for the inner wall of a metal pipe. Background technique [0002] With the development of the industrialization process, the development of technical fields such as construction industry and pipeline transportation is advancing by leaps and bounds. In these application fields, a large number of metal pipes of different shapes are involved and used. [0003] In the follow-up maintenance of metal pipes, rust removal is a relatively important operation. Metal pipes, including metal straight pipes and metal pipes, are known to be relatively simple to remove rust on the outer surface of metal pipes, but more complicated to remove rust inside. The chemical method is used to remove rust on the inner wall of the metal pipe, that is, to use acid or lye to clean the inside of the metal pipe. This method usually directly puts t...

[0003] In the follow-up maintenance of metal pipes, rust removal is a relatively important operation. Metal pipes, including metal straight pipes and metal pipes, are known to be relatively simple to remove rust on the outer surface of metal pipes, but more complicated to remove rust inside. The chemical method is used to remove rust on the inner wall of the metal pipe, that is, to use acid or lye to clean the inside of the metal pipe. This method usually directly puts the metal pipe into the rust remover solution for all-round rust removal, but this The rust remover used in this way is excessive, resulting in waste of cost, and the excessive rust remover will cause corrosion to the position where the metal pipe does not have a rust layer, and damage the metal pipe. Although the rust removal problem is solved, it will reduce the metal The service life of the tube is not worth the candle
