Cleaner for inner wall of steel pipe

Abstract

The invention relates to a cleaner for the inner wall of a steel pipe, which comprises a water pump and a four-way reversing valve, wherein the four-way reversing valve is provided with a water inlet pipe, a drain pipe, a left connecting pipe and a right connecting pipe; the end parts of the two connecting pipes are respectively connected with a casing pipe; a cavity, which is communicated with the connecting pipes, is arranged in the casing pipe; the front end of the casing pipe forms a socket which matches with the end part of the steel pipe; and the cavity is communicated with the socket. The invention has a reasonable and simple structure, and is especially suitable for long thin stainless steel coil pipes. The actions of the water pump and the four-way reversing valve can circularly clean the inner wall of the steel pipe, thereby enhancing the efficiency; and the clamping mechanism can clamp the steel pipe, thereby greatly enhancing the production safety. The complete device is simple and convenient to operate, lowers the production cost, enhances the safety and is suitable for popularization.

Description

technical field [0001] The invention relates to a steel pipe processing device, in particular to a steel pipe inner wall cleaning device for cleaning the inner wall of a slender stainless steel coil. Background technique [0002] After the steel pipe is processed and deformed, there will be some impurities such as lubricating grease and metal particles on the surface of the inner wall. If it is not cleaned, it will affect the service life and scope of use of the steel pipe. At present, the inner wall of small seamless steel pipes is generally cleaned by soaking the steel pipes in a liquid medium, and then the workers clean them manually with spray guns. During this process, it is easy to cause the cleaning liquid to leak out. If it splashes on the workers, it will cause injury, and The leakage of cleaning fluid will affect the cleaning effect and efficiency.

Problems solved by technology

[0002] After the steel pipe is processed and deformed, there will be some impurities such as lubricating grease and metal particles on the surface of the inner wall. If it is not cleaned, it will affect the service life and scope of use of the steel pipe.

At present, the inner wall of small seamless steel pipes is generally cleaned by soaking the steel pipes in a liquid medium, and then the workers clean them manually with spray guns. During this process, it is easy to cause the cleaning liquid to leak out. If it splashes on the workers, it will cause injury, and Leakage of cleaning fluid will affect cleaning effect and efficiency

A small number of steel pipe inner wall cleaning devices have complex structures and high costs, which are not suitable for application and production

In addition, the current cleaning device, such as a seamless steel pipe inner wall cleaning spray gun disclosed in Chinese patent 200820153201.5, relies on the spray force of the nozzle to clean the inner wall of the steel pipe. Due to the limited spray force of the nozzle, this cleaning spray gun is not suitable The inner wall of the slender stainless steel coil cannot be cleaned
