AI Technical Summary

Technical Problem

Existing circulating regeneration media filters have poor sealing between the tank and the tank cover, which easily creates gaps. Furthermore, the filter element hose is not securely fixed and is prone to deformation or breakage, affecting the normal operation of the filter.

Method used

It adopts a double-ring sealing design, and has a lower flange, an upper flange and a partition plate device between the tank body and the tank cover. It uses an upper tube sheet and a lower tube sheet structure with one long and one short, combined with a vertical support frame to enhance the sealing effect and the fixed stability of the filter element hose.

Benefits of technology

It improves the sealing effect between the tank body and the tank cover, avoids the aging and deformation of the sealing ring, ensures that the filter does not fail to seal in high-temperature environments, extends the service life of the filter element hose, and maintains the normal operation of the filter.
