Steel pipe degreasing system

Abstract

The invention discloses a steel pipe degreasing system. The steel pipe degreasing system is characterized by comprising a multifunctional swing arm unit, an inner degreasing positioning unit and a gas-liquid composite purging unit, wherein the multifunctional swing arm unit is used for carrying out swing vibration and inclined motion on a plurality of steel pipes which are integrally placed together; the inner degreasing positioning unit is used for positioning the steel pipes which are integrally placed; and the gas-liquid composite purging unit is used for cleaning and purging the steel pipes with degreasing liquid. The steel pipe degreasing system aims to reduce the occupied space of equipment, reduce the manufacturing and maintenance difficulty of the equipment and improve the degreasing productivity of products, so that the comprehensive manufacturing cost of the equipment is reduced. The multifunctional swing arm unit adopts four groups of swing arm units with the same configuration, different combinations of motion time, positions and distances are implemented, four functions of feeding and discharging, pipe body vibration, in-pipe exhaust and draining required during steelpipe degreasing are realized at one station, the process route is shortened, the number of equipment is reduced, and the manufacturing and control stability is improved.

Description

Technical field: [0001] The invention relates to the technical field of a steel pipe production line, in particular to a cleaning system for degreasing steel pipes. Background technique: [0002] After the steel pipe is cold-rolled, it is necessary to clean the grease attached to the upper surface of the inner and outer circles of the steel pipe, and use an alkaline degreasing solution to wash the surface to meet the user's requirements for delivery status. Usually, the degreasing machine in the production line uses a single station to degrease a single steel pipe. A nozzle is installed on the single station for internal degreasing, cleaning and purging; the steel pipe rotates on the single station, and a spray pipe is installed above to degrease and clean the outer surface of the steel pipe. [0003] When the steel pipe is degreased, a single steel pipe is transported to a group of rotating tugboats, and nozzles are inserted into its fixed end to treat the inner surface wi...

AI Technical Summary

Problems solved by technology

When degreasing the outer surface, the degreasing liquid and the clean ring water are in the open space, and the optimum temperature for degreasing is about 60°C, which will cause the space to be filled with water vapor and affect the peripheral equipment
