AI Technical Summary

⚠Technical Problem

V-type filters are prone to accumulating dirt during use, which affects the flow rate of sewage. Furthermore, backwashing can easily cause sand to escape from the filter media, resulting in unsatisfactory interception effect and increased economic investment.

⚗Method used

A structure was designed that includes a filter body, a sand tank, a sewage discharge tank, a V-shaped groove, a motor, a sewage pump, a lead screw, a cleaning component, and a filter screen. The motor drives the lead screw to drive the cleaning component to achieve a self-cleaning function, and the filter screen prevents sand from escaping from the filter media.

🎯Benefits of technology

The self-cleaning function of the V-type filter bed was achieved, reducing sand loss from the filter media, improving wastewater treatment efficiency, and reducing economic costs.
