Steel pipe cleaning device capable of achieving timely opening and closing of cleaning fluid

Abstract

The invention discloses a steel pipe cleaning device capable of achieving timely opening and closing of cleaning fluid. The steel pipe cleaning device comprises a main pipe body, a fluid inlet end is formed at the rear end of the main pipe body, a coaxial spraying head is installed at the front end of the main pipe body, and a fluid outlet capable of being communicated with the fluid inlet end is formed in the front end of the spraying head to form a spraying nozzle. The steel pipe cleaning device is characterized in that the main pipe body is further internally provided with a timely opening and closing mechanism capable of achieving the timely opening and closing control function of the cleaning fluid. The timely opening and closing mechanism comprises the spraying head capable of being axially installed in a sliding mode, and further comprises an opening and closing spring which is located in an opening and closing spring installation cavity communicated with the fluid inlet end, the rear end of the opening and closing spring is connected to the rear end of the opening and closing spring installation cavity in an abutting mode, the front end of the opening and closing spring is connected to the rear end of the spraying head in an abutting mode, and an inlet of a fluid channel where the liquid outlet in the spraying head is located is located in the side surface of the spraying head. The steel pipe cleaning device can achieve the function of timely opening and closing of the cleaning fluid and has the advantages of being convenient to operate, capable of saving more cleaning fluid, capable of cleaning the inner wall and the outer wall of a steel pipe at the same time, good in cleaning effect, high in cleaning efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of steel pipe production, in particular to a steel pipe cleaning device capable of realizing instant switching of cleaning fluid. Background technique [0002] After the steel pipe is produced by cold rolling, some impurities such as stains, impurities and oil will remain on the inner and outer walls of the steel pipe. If these impurities are not cleaned up, the inner and outer walls of the steel pipe will be corroded, which will easily cause the steel pipe to crack. Damage, resulting in a decline in the quality of the steel pipe, reducing the service life of the steel pipe, so the cleaning of the inner and outer walls of the steel pipe is essential and very important. At present, when cleaning the inner and outer walls of the steel pipe, usually a common straight-through spray gun or nozzle is used to spray the cleaning liquid on the inner wall of the steel pipe at the entrance of the steel pipe. This exis...

AI Technical Summary

Problems solved by technology

[0003] 1. It can only be cleaned by aligning the outer wall or inner wall of the steel pipe alone, and the cleaning efficiency is low

2. When cleaning, the on-off valve is generally installed separately. Open the on-off valve first, and then align it with the steel pipe for cleaning. Part of the cleaning fluid will be lost, resulting in waste; if the on-off valve is aligned with the steel pipe first, it will cause inconvenience in operation.

3. When cleaning, the water flow with constant water speed is used for cleaning, and the cleaning effect is limited
