Description

Technical Field

[0001] The utility model relates to the technical field of waste paper recycling, in particular to a waste paper recycling device used for papermaking. Background Art

[0002] With the development of the economy and society, the use of paper has increased rapidly, and a large amount of waste paper has been generated. Waste paper generally includes various waste cardboard boxes, trimming paper, packing paper, paper for enterprises and units, paper for engineering projects, books, periodicals and newspapers, etc. The recycling of waste paper has become one of the focuses of people's urgent attention.

[0003] A Chinese patent with prior art authorization announcement number CN215925437U discloses a waste paper recycling device for papermaking, which introduces waste paper into a collecting hopper along a feed pipe, turns on a first motor, drives a shaft and a second blade to rotate, and under the action of the staggered correspondence between the position of the first blade and the position of the second blade, the scraps in the collecting hopper are shredded, and the waste paper is fully shredded under the cutting action of multiple sets of blades. During the shredding process of the waste paper, a nozzle is turned on, and when the position of the nozzle corresponds to the position of the second blade, the waste paper in the collecting hopper is soaked, which is beneficial to making the waste paper soft and easy to shred, and on the other hand, the water content in the waste paper is increased, which is beneficial to making the stirring rod easy to slurry and improve the dissolution efficiency during the stirring process. The waste paper falls into the water body, and the second motor is turned on to drive the stirring rod to stir, so as to stir the shredded waste paper and the water body. While stirring, the electric heating plate is turned on to increase the temperature of the surrounding water body, which is beneficial to accelerate the dissolution rate of the waste paper and make the waste paper fully dissolved. After the stirring is completed, the discharge pipe is turned on and the waste paper is discharged along the discharge pipe.

[0004] Although the above patent can stir the shredded waste paper and water by a stirring rod, which makes it easy to produce pulp and improve the dissolution efficiency, the shredding of the waste paper and the stirring of the shredded waste paper and water are carried out in different chambers, resulting in a large space occupied by the entire device, and subsequent stirring is only performed by a stirring rod. If there is still waste paper that is not fully shredded, the dissolution efficiency will be reduced and the recycling rate will be reduced.

[0005] Therefore, the applicant proposes a waste paper recycling device for papermaking to solve the above problems. Utility Model Content
