[0035] In this embodiment, the material and water enter the inside of the drum body 1 through the inlet end of the drum body 1, and the drum body 1 is driven to rotate by the driving mechanism 4. When the drum body 1 rotates, the crushing guide plate 2 and the negative angle flap 3 are driven to move synchronously; the mixture of the material and the water is continuously cut by the crushing guide plate 2 and pushed toward the outlet end of the drum body 1, and the mixed material is continuously flipped up by the negative angle flap 3. The mixed material after flipping up falls under the action of gravity, which can generate surges on the inner wall of the drum body 1. At the same time, due to the negative angle assembly (such as Figure 3 As shown), the negative angle flap 3 is located on the front side wall of the drum body 1; when the drum body 1 rotates 180° clockwise (as shown Figure 4 As shown in the figure, the negative angle flap 3 is located on the rear side wall of the drum body 1, and has a certain inclination angle in the direction away from the mixed material; under the joint action of the crushing guide plate 2 and the negative angle flap 3, the mixed material can be pushed and rolled backwards, thereby increasing the mixing time and cutting times of the mixed material inside the drum body 1, so that the material can be fully crushed and mixed.

[0036] It should be noted that Figure 2 , Figure 3 , Figure 4 The direction indicated by the hollow arrow is the direction in which the mixed material is advanced.

[0037] By adopting this solution, the present invention can fully crush and stir materials with complex components through the arrangement of the above-mentioned structure, thereby eliminating the need for the arrangement of screening equipment and optimizing the pulping process.

[0038] Further optimization scheme, such as Figure 2 As shown, the angle a between the negative angle flap 3 and the crushing guide plate 2 on the same side is set to 60°-80°; the angle b between the negative angle flap 3 and the axis of the drum body 1 is set to 3°-5°.
