AI Technical Summary
After prolonged operation, existing bag filters suffer from impurities adhering to the filter bag walls, leading to reduced filter flow, frequent shutdowns for maintenance, and impacting filtration efficiency and production continuity.
A high-efficiency bag filter with an impeller and a cleaning brush was designed. The impeller is driven to rotate by the impact force of the water flow at the inlet, which in turn drives the cleaning brush to clean the surface of the filter bag in real time. The cleaning brush includes a frame and a soft brush, which is bolted to the frame to realize the self-cleaning function of the filter bag.
It effectively reduces filter bag pore clogging, improves filtration efficiency, ensures smooth flow of filtrate, reduces downtime maintenance frequency, and improves equipment stability and flexibility.
