when the device is operated, if the linear speed of the plurality of rotating rods 927 on the first stirring mechanism 92 and the second stirring mechanism 93 is 1m/s (same as that in the first embodiment), the viscous materials are stirred and scattered only at the first stirring mechanism 92 and the second stirring mechanism 93, and uniform mixing of all the viscous materials cannot be realized.

If the rotational linear velocity of the plurality of rotating rods 927 of the first stirring mechanism 92 and the second stirring mechanism 93 is 0.2m/s (less than the velocity range of 0.5m/s to 3m/s specified in the present invention), the paper sludge is difficult to be uniformly mixed at the first stirring mechanism 92 and the second stirring mechanism 93, and a decrease in mixing efficiency may be caused.
Comparative example three
The difference between the comparative example and the first embodiment is as follows: the rotating speed of the rotating disc 1 is 30r/min (which is greater than the speed range 2r/min to 20r/min of the rotating disc 1 specified by the invention);
