AI Technical Summary
When filtering waste liquid containing flocculent materials, existing plate filters tend to form a film layer on the filter surface, which leads to a decrease in filtration efficiency and requires frequent cleaning or replacement, affecting production continuity.
By using a filter cartridge instead of a plate filter screen, and combining the design of the output pipeline and backwash pipeline, the filter cartridge can reverse the flow of liquid by impacting the filter screen surface through the backwash pipeline when the liquid output decreases, thus restoring the flow of liquid and extending the service life of the filter cartridge.
It extends the effective service life of the filter cartridge, reduces the frequency of disassembly for cleaning and maintenance, and improves the continuity of production.
