Flat plate type microfilter

Abstract

The utility model relates to a flat plate type microfilter. The filter screen is horizontally placed and fixed, so that water enters the water outlet tank from the water inlet pipe and then flows onto the filter screen to be filtered, impurities left on the upper portion of the filter screen are backwashed through the backwash water pipe and the backwash nozzle which are driven by the lead screw, and the impurities are washed onto the guide plate through backwash water flow. Due to the design of the flat plate type filter screen, the structures of the impurities and the fine particulate matters cannot be damaged in the filtering process, and the water quality cannot be damaged. One motor synchronously drives the two lead screws to rotate to drive the backwashing water pipe and the backwashing nozzles to reciprocate below the filter screen to perform backwashing work, so that the whole structure is simple, the control is convenient, the operation is stable, and the backwashing work of the filter screen can be effectively realized.
