AI Technical Summary

Technical Problem

Existing pipe inner wall cleaning devices suffer from uneven cleaning, poor targeting, insufficient precision, and poor versatility. They are particularly difficult to completely remove impurities in pipes with a large length-to-diameter ratio and may damage the inner wall of the pipe.

Method used

The multi-nozzle cleaning device uses a moving cylinder to move the nozzle mounting base on a linear guide rail. The combination of self-rotating and non-rotating nozzles ensures thorough cleaning of the pipe wall without any dead angles. An air heater regulates the airflow rate and temperature, and combined with a conveying mechanism and a slag removal mechanism, it achieves precise and efficient cleaning.

Benefits of technology

It enables precise and efficient cleaning of the inner walls of pipes, ensuring consistent cleanliness, reducing damage to the inner walls of pipes, and improving cleaning efficiency and effectiveness.

Abstract

This invention discloses a pipe internal cleaning device, belonging to the technical field of pipe cleaning. It includes a frame with a cleaning mechanism mounted on it. The cleaning mechanism includes a linear guide rail, on which a nozzle mounting seat is movably connected. A movable cylinder is positioned between the nozzle mounting seat and the linear guide rail, with the cylinder seat connected to the linear guide rail and the piston rod connected to the nozzle mounting seat. The nozzle mounting seat has multiple nozzles, each including an outlet pipe and a mounting base for fixing the outlet pipe. The mounting base for the first nozzle is longer than the mounting bases for subsequent nozzles by a distance h. During cleaning, the piston rod of the movable cylinder extends, moving the outlet pipe of the nozzle into the heat exchange tube. A distance h is maintained between the mounting bases of the nozzles other than the first nozzle and the end of the heat exchange tube. This invention uses an automated device to treat pipe residue and cleaning fluid, achieving precise, efficient, and standardized pipe internal wall cleaning.
