Push type brush for degreasing cleaning of steel pipe inner wall

Abstract

The invention relates to a push type brush for degreasing cleaning of a steel pipe inner wall. The push type brush comprises a brush rod and at least one propeller blade which can push the brush rod to move under liquid or gas, wherein the propeller blade is arranged on the end of the brush rod, and the brush rod is provided with brush bristles. The push type brush for degreasing cleaning of the steel pipe inner wall provided by the invention has the advantages that the structure is simple, the conception is novel, the manufacture is easy, the steel pipe inner wall is effectively cleaned at high efficiency so as to achieve the special cleanness requirements such as pipes for nuclear power, the steel pipe inner wall after cleaning is not damaged, and the quality of a steel pipe is unaffected; and the steel pipe inner wall is easy to clean up no matter how long the steel pipe, the time is saved, the labour is saved, and the operational efficiency is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe cleaning equipment, in particular to a push-type brush used for degreasing and cleaning the inner wall of steel pipes. Background technique [0002] Stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength is the same, the weight is lighter, so it is Widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc. Steel pipes are generally drawn gradually from thicker steel pipes to thinner steel pipes. Special drawing oil is required during the drawing process, and oil stains need to be removed after drawing, especially for high-precision stainless steel used in nuclear industries or power stations. The steel pipe does not allow a lit...

AI Technical Summary

Problems solved by technology

This method has the disadvantages of outdated technology, poor effect, more labor and high labor intensity.

For the inner wall of steel pipes, it is extremely difficult to clean, especially for slender pipes. The methods of manual cleaning of steel pipes such as soaking, pickling and pumping cannot be thoroughly cleaned. Therefore, ordinary washing methods cannot reach the level of nuclear power pipes or power station pipes. requirements

In the prior art, in order to clean the inner wall of the steel pipe, a hair brush is also used. Because the length of the steel pipe generally reaches more than 10 meters, when this type of steel pipe is scrubbed with a hair brush, it is necessary to use an extended connecting rod to drive the hair brush to rotate. The rod will scratch the inner wall of the steel pipe, resulting in unqualified roughness of the product
