AI Technical Summary

Technical Problem

The existing activated carbon backwash connection structure is inconvenient to install. When the flange holes are not aligned, it takes a lot of time to align them. In addition, impurities in the backwash water can easily enter the activated carbon tank and affect the effect.

Method used

The system employs a connection assembly that includes a fixed flange, annular groove, rigid pipe, stop block, plug pipe, rubber sealing ring, and movable flange, in conjunction with a filter assembly, to ensure a tight and convenient connection. The filter assembly also filters out impurities, preventing them from entering the activated carbon tank.

Benefits of technology

It enables convenient installation and efficient filtration of activated carbon backwashing connection, ensures connection sealing and backwashing effect, prevents impurities from entering the activated carbon tank, and improves the flexibility of use and the effect of backwashing.
