Composite screening machine for waste paper pulp separation

The utility model relates to a composite screening machine for separating waste paper pulp. Wherein the waste slurry pipe is communicated with the top of the tank body, and the slurry discharging pipeis communicated with the side wall close to the bottom of the tank body. The method is characterized in that the method is characterized by comprising the following steps; wherein the screening module is arranged in a tank body and is used for dividing the interior of the tank body into a screening cavity and a discharging cavity which are longitudinally distributed; wherein the dispersing assembly is driven by a motor to rotate, located in the screening cavity and used for splitting waste paper pulp in the screening cavity, and the pulp pricking module is arranged below the screening moduleand driven by a driving device to penetrate through the screening module in a clearance mode. The screening module comprises two layers of circular screen plates which are arranged at intervals and ofwhich the edges are embedd
