Rust removing device for inner wall of metal pipe

Abstract

The invention discloses a rust removing device for the inner wall of a metal pipe. The rust removing device for the inner wall of the metal pipe comprises a base table, the metal pipe, a servo motor,a guide block and a hopper. The metal pipe is a hollow structure body and is obliquely arranged relative to the base table. The servo motor is located at the end where the distance between the metal pipe and the base table is the shortest, and the servo motor is electrically connected with an external power source. The guide block is located in the metal pipe and connected with the rotating shaftend of the servo motor through a screw rod. The hopper comprises a feeding hopper body and a discharging hopper body, the discharging hopper body corresponds to the metal pipe, a high-pressure sprayeris arranged in the feeding hopper body, and the tail end of the high-pressure sprayer is connected with external gas supply equipment. According to the rust removing device for the inner wall of themetal pipe, rust removing treatment is carried out on the inner wall of the metal pipe through a sand blasting process, rust removing efficiency is high, the effect is good, and the labor intensity ofworkers is reduced.

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 for the inner wall of a metal pipe. Background technique [0002] With the development of industrialization, the construction industry, pipeline transportation and other technical fields have developed by leaps and bounds. In these application fields, a large number of metal pipes of different shapes are involved and used. [0003] The most important part in the processing of metal pipes is rust removal. As we all know, the rust removal on the outer surface of metal pipes is relatively simple, but the internal rust removal is more complicated. The traditional internal rust removal method is to use acid or alkali to remove rust. Internal cleaning, or operators derusting metal pipes with angle grinders and round wire brushes. [0004] The first method will cause damage to the metal pipe, corrode the metal pipe, and have a certai...

Problems solved by technology

[0004] The first method will cause damage to the metal pipe, it will corrode the metal pipe, and at the same time, it will have a certain impact on the ecological environment; in the second method, the staff can only derust the two ends of the metal pipe according to the required process, but the middle part is derusted. The effect is not easy to meet the standard, and because the metal pipes used in pipeline transportation and other industries are generally more than 1 meter, it is difficult for construction personnel to completely remove the rust inside the metal pipes, resulting in low rust removal efficiency and poor effect, and increases the operator's work.
