AI Technical Summary
Technical Problem
The existing connection method of the backflush pipe in emulsion filtration device is prone to sealing failure, which leads to filter element caking and blockage, shortening its service life.
Method used
The system employs a backflushing pipe design, including a flange seat, bearing outer ring, bearing inner ring, sealing ring, and backflushing branch pipe. It is sealed with a rubber ring and uses a differential pressure sensor to control the backflushing motor to achieve reverse flushing, thus avoiding seal failure and wear.
Benefits of technology
It effectively prevents filter element clogging, extends service life, ensures backwashing effect, and avoids emulsion leakage and ball wear.
