Bidirectional filter box for water intake suspended matter in floating pumping

A bidirectional filter box for water intake suspended matters in floating pumping. Steel channel columns and angle irons connect into loose-leaf base plate frame with a plurality of grids; each grid of the loose-leaf base plate framework is equipped with a loose-leaf plate; two sides of the loose-leaf plate are connected to steel channel columns through rotating shafts, which can only rotate for 90 DEG; one end of the loose-leaf plate is connected to a lever; levers are arranged on edges of a left plate frame and a right plate frame; and a loose-leaf plate can overturn for 90 DEG under effect of the lever. The loose-leaf base plate frame with a plurality of grids combines with the right plate frame, the left plate frame, a rear body plate frame and a sharp triangle frame to form the filter box; a front box and a rear box of the filter box are arranged with a flocculation flap frame respectively; a central part in the right plate frame of the filter box is provided with a water pipe inner box frame, which is e
