The filter consists of the shell, the multi-element filter element, the anti-flushing mechanism, and the differential pressure controller. Casing of diaphragm plate inside cavity can be divided into upper and lower two cavity, the cavity is equipped with multiple filter core, so that make full use of the filter space, significantly reduced the volume of the filter, are installed in the inferior vena recoil wash suction cups. At work, the turbid solution enters the filter chamber through the entrance and enters the inner cavity of the filter core through the diaphragm hole. The impurities that are larger than the gaps in the filter core are truned away, and the net fluid reaches the upper chamber through the gap and is finally sent out from the outlet.
Through the filter screen, the process of the process is carried out through the outlet, and the particles in the water are trapped inside the filter. So continuously circulation, more and more particles trapped down, filtration speed slower and slower, and imports of sewage is still continue to enter, filter hole will be more and more small, thus produce pressure difference between inlet and outlet, when poor magnanimous to set data, differential pressure transmitter will be routed to the controller, control system startup drive motor through the mechanical drive shaft rotation, open the outlet at the same time, by the discharge outlet, when the screen is clean, differential pressure drop to the minimum, the system returns to the initial filter, normal operation of system
