AI Technical Summary

Technical Problem

Existing cleaning devices are prone to scratches or burrs when cleaning the threads of metal pipes. They have poor automation adaptability, low efficiency of non-heated purging, and difficulty in effectively removing residual liquid from the bottom of the thread grooves.

Method used

A non-contact hot air cleaning device is adopted, which uses inclined hot air guide pipes and nozzles, combined with rotating steel pipes and mobile support units, to clean the steel pipe threads in all directions with hot air. A PID temperature control system is used to maintain a constant airflow temperature to avoid physical contact, and photoelectric switches are used to achieve automatic control.

Benefits of technology

It achieves efficient cleaning without scratches or burrs, improves automation adaptability, increases cleaning coverage from 75% to 99.5%, reduces processing time to 3 minutes, and increases thermal efficiency to 95%, significantly improving adaptability and efficiency.

Abstract

The utility model relates to a kind of metal pipe automatic water blowing cleaning device. Including movable support unit, the movable support unit is provided with the hot air guide pipe of inclined upward arrangement, the hot air guide pipe one end is provided with nozzle, the hot air guide pipe other end is connected the air outlet of hot air fan, the air inlet of hot air fan is connected with air blower, steel pipe is located on rotating device, the rotating device drives steel pipe rotation, the movable support unit drives hot air guide pipe, nozzle reciprocating movement along the length direction of steel pipe;The air blower provides cold air into hot air fan, and hot air fan heats cold air, forms hot air, and then hot air flows to nozzle through hot air guide pipe, nozzle sprays hot air and blows towards rotating steel pipe thread, and hot air evaporates residual drips on the bottom of steel pipe thread. The application is non-contact to clean steel pipe thread surface in all aspects, which can clean in place, avoid scratches or burrs, improve adaptability and reduce manual operation.
