Liquid flows into the filter via the inlet and then flows through the internal surface of filter screen and goes out from the outlet. Impurities are intercepted on the inner surface of the filter screen and the filter cake slowly accumulates which leads to gradually pressure drop increasing between the inlet and outlet. The flux of the filter screen becomes lower.
When it reaches the preset pressure drop or time the self-cleaning program is triggered. The gear motor drives the back-flushing turning arm aiming at one filter screen. The upper end of the screen is sealed and the lower end is connected to the cleaning nozzle. And then the cleaning valve opens and connect the screen and discharging pipe. The differential pressure between the filter element’ s outside and discharging nozzle will make the filtrate back-flush the filter screen filter cake dislodged and be purged downward into the sewage pipe.
Positioning disc and cleaning turning arm are installed on the shaft driven by the gear motor. Each positioning hole on the disc matches each screen and cleaning arm is corresponding to one hole. When one hole reaches the channel of positioning sensor the sensor output the signal to stop the gear motor. The cleaning arm has aimed at one element at the same time. The cleaning
valve opens for several seconds till the element is cleaned. Then the gear motor continues rotating. When the next hole on disc reaches the sensor channel the gear motor will stop and the next screen is cleaned.
