AI Technical Summary

⚠Technical Problem

In existing technologies, when fracturing fluid is returned, the accumulation of sludge causes filter screen blockage, affecting filtration efficiency, and filtration operations need to be suspended for filter screen disassembly and cleaning.

⚗Method used

A flowback fracturing fluid filtration device is designed, comprising a pipe body, a filter assembly, and a limiting assembly. The sludge on the filter plate is scraped into the collection frame by a scraper, and the opening and closing of the channel is controlled by the limiting plate to realize the collection and transfer of sludge and ensure uninterrupted filtration.

🎯Benefits of technology

It enables automatic collection and transfer of sediment during continuous filtration, improving filtration efficiency, preventing filter clogging, ensuring filtration effect, and simplifying the cleaning process.
