Microfiltration machine is a device of mechanical filter, the maintransmission device, the overflow weir water distributor, water flushingdevice, filter cartridge, main components such as the base, stainlesssteel strainer screen. Its working principle is to deal with the waterinto the water from the overflow pipe mouth, the transient steady flow,even from the water outlet overflow, distribution in the cartridgestrainer rotating in the opposite direction, water flow and the filtertube wall relative shearing movement, water filtration efficiency,solids separation by intercepting, tumbling down the cylinder spiralguide plate from the other end of the filter cylinder, waste water fromthe filter to filter out the door in a cartridge cover on both sidesunder the action of diversion from below the tank flows. The filtercylinder is equipped with a flushing water pipe, water pressure(3kg/cm2) fan-shaped spray to wash dredge filter, to ensure filteralways maintain good filtering ability.
