Pulping machine

A pulping machine, comprising:

• a frame provided with a mixing chamber and a dispersing chamber;
• a mixing device accommodated in the mixing chamber;
• and
• a dispersing device accommodated in the dispersing chamber,
• wherein the dispersing chamber is provided with a liquid inlet, the mixing chamber is provided with a liquid outlet and a powder material inlet, the liquid inlet, the dispersing chamber, the mixing chamber and the liquid outlet are sequentially communicated;
• the powder material inlet, the mixing chamber and the liquid outlet are sequentially communicated along a flow direction of powder material;
• the liquid outlet is connected with a filter device;
• wherein the mixing device comprises a centrifugal impeller, the centrifugal impeller is pivotally connected to the frame through a rotating shaft;
• an impeller body of the centrifugal impeller is provided with a plurality of upper blades, the plurality of the upper blades are spaced apart around a circumferential direction of the impeller body;
• the impeller body of the centrifugal impeller is connected with a plurality of lower blades, the plurality of the lower blades are located directly below the impeller body and spaced apart around the circumferential direction of the impeller body;
• the lower blade extends to an edge of a bottom of the impeller body along a radial direction of the impeller body from inside to outside;
• the lower blade is provided with a plurality of turbulent flow through holes;
• a bottom of each upper blade is connected with a bottom of one of the lower blades, and the bottom of the upper blade continues to extend along the radial direction of the impeller body from the edge of the bottom of the impeller body to form a protrusion, an outermost end of the lower blade extends to directly below the protrusions, so that a stirring zone is formed between two adjacent protrusions;
• the plurality of the turbulent flow through holes of the lower blade are located on a horizontal side of the stirring zone;
• the upper blade is a monolithic structure and extends downward spirally and obliquely along the circumferential direction of the impeller body;
• the mixing device comprises a dispersing centrifugal wheel body provided with a plurality of cutting rods, the plurality of cutting rods are spaced apart on a side wall of the dispersing centrifugal wheel body;
• the dispersing centrifugal wheel body is connected to a top of the impeller body;
• the dispersing centrifugal wheel body is detachably connected to the impeller body;
• a side wall of the cutting rod has a plurality of sharp edges;
• the dispersing centrifugal wheel body is arranged in a pyramidal structure, and a cross-sectional outer profile of the dispersing centrifugal wheel body gradually becomes larger from top to bottom;
• the plurality of the cutting rods extend downwards spirally and at intervals along a circumferential direction of the dispersing centrifugal wheel body to form a dispersing unit combination, and a plurality of the dispersing unit combinations are distributed at intervals around the circumferential direction of the dispersing centrifugal wheel body.
