AI Technical Summary

Technical Problem

Traditional siphon tanks in the chemical industry suffer from frequent cleaning, low filtration efficiency, and easy clogging of the filter screen. In particular, impurities are prone to crystallization and deposition in low-temperature environments, affecting the safe operation and lifespan of centrifugal pumps.

Method used

Design a siphon tank with filtration function, including a filter cartridge, a temperature control device and a cleaning pump. The inner and outer surfaces of the filter cartridge are coated with polytetrafluoroethylene. The flocculation of impurities is prevented by rotating flow and temperature regulation. The detachable structure facilitates cleaning.

Benefits of technology

It effectively reduces the risk of filter cartridge clogging, improves filtration efficiency, extends equipment operating cycle, reduces maintenance frequency and cost, and ensures the safe and long-term operation of centrifugal pumps.
