[0002] With the rapid development of society, the demand for paper in daily life and all walks of life is getting higher and higher, and the quality requirements for paper are becoming more and more stringent.

[0003] During the paper production process, manufacturers will cut paper into different sizes according to customer needs, so that it can be used for subsequent processing such as packaging boxes, wrapping paper, book printing, etc. During the paper cutting process, a large amount of irregular waste paper will be generated. In order to recycle and reuse the waste paper, manufacturers will use shredders to evenly crush it for subsequent recycling of the waste paper. When the shredders actually crush the waste paper, a large amount of fine dust will be generated. The fine dust will fly out of the shredders at high speed along with the crushed paper blocks, resulting in a large amount of fine dust floating in the workshop, which not only pollutes the environment of the production workshop, but also damages the health of the operators. In addition, the fine dust is paper fiber, and when it gathers more, it is prone to natural accidents, causing safety hazards in production. Utility model content:

Specific implementation method:

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0016] like Figure 1As shown, the waste paper recycling and processing system comprises a paper shredding fan 1, the output end of the paper shredding fan 1 is connected with a paper shredding conveying pipe 2, the output end of the paper shredding conveying pipe 2 is connected with the top wall of a storage box 3, the paper shredding conveying pipe 2 is connected with a dust suction pipe 4, a first pipeline fan 5 is installed on the dust suction pipe 4, the output end of the dust suction pipe 4 is connected with the top end of the side wall of a water dust removal box 6, the bottom end of the side wall of the water dust removal box 6 is connected with a water circulation pipe 7, a water pump 8 is installed on the water circulation pipe 7, and the output end of the water circulation pipe 7 is connected with a shower tray 9. The shower plate 9 is fixedly mounted on the top wall of the inner cavity of the water dust removal box 6, an exhaust port is opened at the top end of the other side wall of the water dust removal box 6, a branch pipe 10 is connected at the top end of the side wall of the storage box 3, the output end of the branch pipe 10 is connected to the dust suction pipe 4, a mesh cover 11 is installed at the input end of the dust suction pipe 4 and the branch pipe 10, a water replenishment valve 12 is installed at the top end of the side wall of the water dust removal box 6, and a mud discharge valve 13 is installed at the bottom end of the other side wall of the water dust removal box 6; a fiber filter mesh cover 22 is installed at the input end of the water circulation pipe 7.

[0017] Specifically, the water dust removal box 6 can filter the fine dust generated by the shredding fan 1 when shredding paper.

[0018] In actual use, the waste paper is put into the shredder fan 1, and the evenly shredded paper blocks are blown into the shredder conveying pipe 2, and finally conveyed to the sealed storage box 3 for temporary storage. At this time, under the suction of the first pipeline fan 5, the small dust generated in the shredder conveying pipe 2 is conveyed to the water dust removal box 6 through the dust suction pipe 4, and the shower plate 9 evenly drips a large amount of fine water droplets from the top of the water dust removal box 6 to the bottom. In this process, the fine water droplets meet and mix with the small dust mixed in the flowing air, so that the fine water droplets filter out the small dust, and the filtered air is discharged from the exhaust port. When there are many shredded paper blocks accumulated in the storage box 3, open the sealed door corresponding to the storage box 3 to remove the shredded paper blocks;

[0019] The water drops dripping in the water dust removal box 6 gather at the bottom of the box, and the small dust carried by the water settles at the bottom of the box. Under the action of the water pump 8, the upper clear water is transported to the shower tray 9 through the water circulation pipe 7, thereby realizing the reuse of water resources; the fiber filter cover 22 can prevent small dust from entering the water circulation pipe 7; the water in the water dust removal box 6 can be replenished through the water replenishment valve 12, and when a lot of paper mud is deposited at the bottom of the inner cavity of the water dust removal box 6, it will be discharged from the mud discharge valve 13;

[0020] The branch pipe 10 absorbs the remaining small dust floating in the storage box 3 to the dust suction pipe 4, and finally transports them to the water dust removal box 6 for filtering. The net cover 11 prevents the shredded paper blocks from being sucked into the dust suction pipe 4 and the branch pipe 10.

[0021] like Figure 1 As shown, in the waste paper recycling system, the exhaust port is connected to a guide pipe 14, a second duct fan 15 is installed on the guide pipe 14, the output end of the guide pipe 14 is connected to the bottom end of the side wall of the air purification cabinet 16, the inner cavity of the air purification cabinet 16 is filled with activated carbon filter cotton 17, fiber filter cotton 18 and non-woven filter cotton 19 from top to bottom, the top wall of the air purification cabinet 16 is connected to an exhaust pipe 20, and a conical wind hood 21 is installed on the top of the exhaust pipe 20.

[0022] Specifically, the air can be further filtered through the air purification cabinet 16 .

[0023] During actual use, the air discharged from the exhaust port of the water dust removal box 6 is transported to the air purification cabinet 16 through the guide pipe 14, and is filtered through three layers of activated carbon filter cotton 17, fiber filter cotton 18 and non-woven filter cotton 19. The small dust carried in the air and the harmful gases generated by the machine can be further absorbed and filtered out, and the pure air is finally discharged through the exhaust pipe 20; when the three-layer filter material has been used for a long time, the corresponding sealed door of the air purification cabinet 16 can be opened to clean or replace its filter material.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
