[0018] like Figure 2 As shown, in order to limit the flow area of ​​the pulp and make the pulp flow in a limited space, the limiting assembly 5 includes a cylinder 10 and a pressure plate 11. The cylinder 10 is installed on the upper wall of the mixing cylinder 1, and the telescopic end of the cylinder 10 passes through the upper wall of the mixing cylinder 1 and extends to the inside of the mixing cylinder 1.

One end of the rotating shaft 8 is rotatably arranged on the bottom wall of the mixing cylinder 1, and the other end of the rotating shaft 8 is fixedly connected to the output end of the rotary motor 7. The spiral blade 9 is arranged around the lower part of the outer wall of the rotating shaft 8, driving the rotary motor 7 to rotate, driving the stud and the spiral blade 9 to rotate, and promoting the waste paper and water at the bottom of the mixing cylinder 1 to flow, so that the waste paper flows rapidly with the water after being soaked, and is crushed.

[0020] like Figure 2 and Figure 3As shown, in order to further promote the pulp and improve the uniformity of its fiber dispersion, the promoting and dispersing component 6 includes a pressure box 12, an air pump 13 and a connecting pipe 14.
