Centring and self-generating fixing device for environment-friendly steel pipe rust removal

Abstract

The invention provides a centring and self-generating fixing device for environment-friendly steel pipe rust removal relates to the technical field of environmental protection. The device comprises afixing pipe, an inner wall of the fixing pipe is fixedly connected with uniformly distributed electromagnetic devices 1, and the inner wall of the fixing pipe is provided with uniformly distributed movable grooves. According to the fixing device, the electromagnetic devices 2 and electromagnetic devices 2 are matched for use, since all the electromagnetic devices 1 have the same magnetism, the electromagnetic devices 2 have the same magnetism and the magnetism of inner sides of the electromagnetic devices 1 is the same as that of the outer sides of the electromagnetic devices 2, the electromagnetic devices 1 and the electromagnetic devices 2 repel each other, meanwhile, movable blocks can move towards the inner sides by the same length under the repulsive action of the electromagnetic devices 1 and the electromagnetic devices 2 such that rolling wheels are clamped and located in the center of the fixing pipe, the centering effect is achieved, the rust removal work is effectively guaranteed, an outer side of a steel pipe makes uniform contact with the rust removal device, and the rust removal quality is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a fixing device for rust removal of environmentally friendly steel pipes that can be centered and generate electricity by itself. Background technique [0002] Steel pipe is a material that is often used in daily life. Due to its high hardness and other excellent properties, steel pipe is widely used in various fields. However, after a long period of use, steel pipe will produce rust, which makes the surface of the steel pipe not beautiful, and the rust is not good. Timely removal of easily corroded steel pipes will affect the service life of the steel pipes, so derusting devices are often used to derust the steel pipes, which is convenient for the later use of the steel pipes. [0003] Most of the current derusting devices are automatic feeding, but it is also necessary to fix the steel pipe during the feeding process to avoid running around the steel pipe and a...

[0002] Steel pipe is a material that is often used in daily life. Due to its high hardness and other excellent properties, steel pipe is widely used in various fields, but steel pipe will produce rust after long-term use, resulting in unsightly surface of steel pipe Timely removal of easily corroded steel pipes will affect the service life of steel pipes, so rust removal devices are often used to remove rust from steel pipes, which is convenient for later use of steel pipes

[0003] Most of the current derusting devices are automatic feeding, but the steel pipes also need to be fixed during the feeding process to avoid the steel pipes from running around and affect the derusting efficiency, and there is no centering device in the current feeding fixing devices, resulting in the steel pipes being fed. Eccentricity often occurs, resulting in uneven contact between the steel pipe and the rust removal device, resulting in insufficient rust removal, which affects later use, and requires repeated rust removal, which increases the cost of rust removal. At the same time, the current feeding device has a fixed size and can only clamp For steel pipes with uniform diameter, when feeding steel pipes with different diameters, it needs to be replaced with the corresponding feeding device, and the replacement process is cumbersome and time-consuming, which reduces the efficiency of rust removal and increases the difficulty of rust removal
