Anti-blocking needle type filter membrane filter

The utility model discloses an anti-blocking needle type filter membrane filter. A cavity is formed in the shell. A filter membrane is arranged at the outlet in the cavity; a blocking cover is installed in the cavity and located above the filter membrane, a plurality of parallelogram overflowing holes are formed in the blocking cover in the circumferential direction, each parallelogram overflowinghole is obliquely formed along the generatrix of the blocking cover, and when water flow enters the blocking cover through the parallelogram overflowing holes, the flow direction of the water flow isobliquely downward in the clockwise direction; a rotating shaft is rotationally connected into the blocking cover, rotating blades are fixedly connected to the rotating shaft, the bottoms of the rotating blades make contact with the filter membrane, and water flow entering the blocking cover pushes the rotating blades to rotate clockwise. The needle type filter can reduce blockage of solid impurities on a filter membrane
