the guide structure (2) comprises a flow collecting box (21), a fixed sleeve (22), a first sleeve (23) and a second sleeve (24), the flow collecting box (21) for guiding flow is fixed in the shell (6), the included angle between the bottom surface of the flow collecting box (21) and the side wall of the shell (6) is 80-85 degrees, the fixed sleeve (22) of a cylindrical structure is arranged at the central line of the flow collecting box (21), the first sleeve (23) of a circular ring shape for preventing backflow is fixed to the bottom end of the first grinding disc (31), the diameter of the first sleeve (23) is greater than the diameter of the fixed sleeve (22), the second sleeve (24) for preventing backflow is fixed on the side circumference of the first grinding disc (31), the cross sections of the first sleeve (23) and the second sleeve (24) are isosceles triangles;

the ground pulp flows into the flow gathering box (21) from the second sleeve (24) and is discharged to the outside of the shell (6) from the flow gathering box (21), the included angle between the bottom surface of the flow gathering box (21) and the side wall of the shell (6) is 80-85 degrees, the pulp is effectively prevented from being accumulated in the flow gathering box (21), the second sleeve (24) is of a circular structure with an isosceles trapezoid cross section, the pulp is effectively prevented from flowing back to the bottom end of the first grinding disc (31), meanwhile, the pulp is further prevented from flowing back through the first sleeve (23), and the discharge quality of the pulp is greatly improved;

and a plurality of stop rods (9) with a cylindrical structure for preventing blockage are vertically arranged on the sealing plate (59).
