Background technique

The pulper is the most commonly used equipment in the paper industry. The pulper mainly mixes and breaks waste paper, cardboard, etc. through the rotation of the rotor of the pulper to generate slurry. However, due to the singleness of the working mode and structure of the current pulper, the following problems are caused: First, the pulping efficiency is low. At present, the pulper only relies on the rotation and stirring of the rotor. It is necessary to increase the stirring time for pulp, and it is also necessary to prolong the stirring time for hard cardboard that is not easy to decompose, which will reduce the pulping efficiency. Second, the quality of the slurry is low. Since the broken material decomposes in different sizes after crushing, resulting in uneven distribution of the slurry and lowering the quality of the slurry. The slurry distribution is more homogeneous, thereby improving the slurry quality.

Therefore, in view of the common problems of low pulping efficiency and low pulp quality in the use of existing pulpers, comprehensive consideration should be given to the working mode and structure of the pulper, and a design with high pulping efficiency and high pulp quality should be made. A kind of papermaking equipment.
