AI Technical Summary

Technical Problem

The existing fracturing fluid proppant delivery pipeline does not move smoothly enough during the cleaning process, resulting in low cleaning efficiency and affecting cleaning quality and efficiency.

Method used

A rapid cleaning structure was designed, comprising a support assembly, a pneumatic push rod assembly, a pushing assembly, a pipe exterior cleaning assembly, and an interior wall cleaning assembly. The pneumatic push rod drives a rotating rod and a sliding plate to adjust their positions, and a high-speed rotating machine and a cleaning scraper are used to clean the interior wall. The pipe exterior cleaning assembly cleans the pipe through a friction belt, and the shock absorber adapts to different pipe diameters.

Benefits of technology

It achieves efficient cleaning of the inner and outer walls of the fracturing fluid proppant delivery pipeline, avoiding the risk of blockage and improving cleaning efficiency and quality.
