[0002] Paper is an indispensable item in people's lives. Enterprises, supermarkets, residential areas, schools, etc. generate a large amount of waste paper every day due to production, packaging, and use. If these waste papers are not recycled, it will not only pollute the environment, but also be an extreme waste of resources. The most widely used way to utilize waste paper is to make recycled paper, which can not only be used to make recycled packaging paper, but also can be used to make recycled newsprint. Recycled paper is made from waste paper as raw material, which is crushed, decolorized and pulped, and then processed through multiple processes to produce paper.
[0003] The prior art has the following problems:
[0004] 1. The existing shredding equipment for waste paper processing does not have a screening function, which results in some unqualified waste paper remaining in the waste paper shredded by the equipment, and then needs to be shredded again, which indirectly reduces the work efficiency and increases the workload of the staff;
[0005] 2. The existing shredding equipment for waste paper processing will generate a large amount of dust particles during the shredding process. However, since the equipment does not have a dust removal mechanism, the surrounding working environment is easily filled with dust when the equipment is shredding, which also poses a serious threat to the health of the workers, indirectly reduces the safety of the work, and has poor practicality. Utility Model Content

[0008] As a preferred technical solution of the present utility model, the size of the dust collecting box is matched with the size of the dust collection box.
[0009] As a preferred technical solution of the present utility model, the position of the filter screen and the position of the fan are arranged corresponding to each other.
[0010] As a preferred technical solution of the utility model, the sieve cylinder is provided with sieve holes, and the sieve holes are provided in several groups and are arranged in equidistant straight lines.
[0011] As a preferred technical solution of the utility model, the rotating rod is installed on the fixed block through a rotating connection.
[0012] As a preferred technical solution of the utility model, the lower parts of both sides of the screening box are inclined.
[0013] As a preferred technical solution of the utility model, the size of the spiral blade is matched with the size of the screen drum.
[0014] Compared with the prior art, the utility model provides a pulverizing device for waste paper processing, which has the following beneficial effects:
[0015] 1. This shredding equipment for waste paper processing, after shredding, the waste paper in the shredding box enters the screen drum through the discharge port, and the motor drives the spiral blade to rotate at a uniform speed and move to the left by controlling the rotation speed and rotation time, wherein the qualified waste paper directly falls through the sieve holes on the screen drum and rolls to the second discharge port for collection during the displacement process, while the unqualified waste paper falls through the first discharge port for recycling. This design avoids the problem that some unqualified waste paper will remain in the waste paper shredded by the equipment, which requires subsequent secondary repeated shredding, thereby indirectly improving the work efficiency and reducing the workload of the staff.
[0016] 2. This kind of shredding equipment for waste paper processing, during the shredding process, starts the fan to discharge the airflow in the dust box, so that the dust hopper absorbs the dust particles and airflow generated by the shredding box when it is working, and introduces them into the dust box through the dust suction pipe, and finally makes them fall into the dust collection box through sedimentation. At the same time, the dust particle gas in the dust box is filtered through the setting of the filter to prevent it from being discharged by the fan. This design improves the dust removal performance of the equipment and avoids the problem that the surrounding working environment is easily filled with dust when the equipment is shredding, which also poses a serious threat to the health of the staff, indirectly improves the safety of work, and is highly practical.
