Macroporous flow-through type stirring paddle blade

The invention discloses a macroporous flow-through type stirring paddle blade, relates to a stirring paddle blade and particularly relates to the macroporous flow-through type stirring paddle blade. The macroporous flow-through type stirring paddle blade disclosed by the invention has the advantage that the problems that a conventional vertical-axis type paddle plate stirrer is poor in stirring and mixing effect and long in stirring time and uses multiple equipment to stir simultaneously so as to increase the energy consumption and investment are solved. The macroporous flow-through type stirring paddle blade comprises a blade main body, wherein the surface of the blade main body is a concave curved surface and is provided with a plurality of long-stripy through holes. The macroporous flow-through type stirring paddle blade is used for stirring in a flocculating tank.
