Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a papermaking pulping device. Background Technology

[0002] In the modern paper industry, waste paper is widely used as an important recycled fiber raw material in the production of packaging paperboard and household paper. Among them, "paperboard" waste is a high-quality recycled resource because of its intact fiber structure and relatively few impurities. In order to achieve efficient recycling of waste paper resources, it is necessary to crush, decompose and make it into uniform pulp as the front-end raw material input of the papermaking system.

[0003] Currently, most common paperboard processing methods use shredders for pretreatment. Although shredders can quickly break up paperboard, they produce dry fiber fragments that need to be mixed with water separately to form pulp. This leads to process disruption, increased overall energy consumption, and the shredding process generates a large amount of dust, posing environmental pollution and safety hazards. In addition, the feeding process still relies on manual continuous feeding, which is not only inefficient but also labor-intensive, making it difficult to meet the needs of continuous and automated production.

[0004] Therefore, it is necessary to design a device for crushing paperboard into pulp for papermaking. Utility Model Content

The crushing blade 10 is rotatably installed in the middle of the crushing cylinder 6. A protective shell 12 is fixedly connected to the lower part of the crushing cylinder 6. A second motor 13 is installed inside the protective shell 12. The protective shell 12 encloses and protects the second motor 13 to prevent water vapor and paper scraps from entering, thereby improving the safety and durability of the equipment. The output shaft of the second motor 13 is connected to the rotating shaft of the crushing blade 10. The controller 5 is electrically connected to the first motor 4, the nozzles 9 and the second motor 13.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a sedimentation tank 14, a filter screen 15, a discharge valve 16, and a reflux structure. The lower part of the crushing cylinder 6 is connected to and communicates with the sedimentation tank 14. The filter screen 15 is provided in the middle of the sedimentation tank 14. The discharge valve 16 is connected to the lower right side of the sedimentation tank 14. The discharge valve 16 is located below the filter screen 15. A reflux structure is provided between the sedimentation tank 14 and the conveying frame 1.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the screening reflux structure includes a reflux frame 17, a push plate 18, a screw 19, a motor 20, an electric guide rail 21, and a reflux plate 22. The reflux frame 17 is connected to the left side of the sedimentation tank 14. The interior of the sedimentation tank 14 is divided by a filter screen 15, and the space above it is connected to the interior of the reflux frame 17. The reflux frame 17 is also connected to the left side of the conveying frame 1. The push plate 18 is slidably installed in the upper part of the sedimentation tank 14, and the push plate 18 is in close contact with the filter screen 15. The screw 19 is rotatably connected to the upper front side of the sedimentation tank 14, and the screw 19 is threadedly connected to the push plate 18.

[0023] like Figure 3 As shown, it also includes auxiliary blades 11. Multiple auxiliary blades 11 are welded circumferentially to the inner wall of the crushing cylinder 6. Both the crushing blade 10 and the auxiliary blades 11 are made of cemented carbide, which has excellent wear resistance and impact resistance, can extend the equipment maintenance cycle and reduce operating costs.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes foot pads 101. Multiple foot pads 101 are provided at the bottom of the sedimentation tank 14 to reduce the vibration generated by the operation of multiple motors and ensure the smooth operation of the overall equipment.

[0025] In actual use, the operator puts the waste paperboard to be processed into the conveying frame 1 from the feeding frame 2. The conveying frame 1 is equipped with a spiral conveying rod 3, which is driven to rotate by a motor 4. The rod continuously and evenly pushes the paperboard from left to right into the crushing cylinder 6, realizing automatic feeding. When the paperboard enters the crushing cylinder 6, the controller 5 starts the motor 13, which drives the crushing blades 10 to rotate at high speed. The inner wall of the crushing cylinder 6 is also equipped with multiple auxiliary blades 11, which form a multi-stage shearing and tearing action with the rotating crushing blades 10 to efficiently crush and de-fiber the paperboard. During the crushing process, the controller 5 will also simultaneously start the water supply system in the water tank 8. The water flows through the ring water pipe 7 and is sprayed into the crushing cylinder 6 by multiple nozzles 9, so that the paperboard is simultaneously wetted during the crushing process. The water spraying and crushing are carried out simultaneously to avoid dust pollution generated during dry crushing, improve the working environment, and provide the necessary moisture for subsequent pulping.

[0026] After being crushed and moistened, the pulp mixture flows from the bottom of the crushing cylinder 6 into the settling tank 14. The settling tank 14 is equipped with a filter screen 15 for screening the pulp. Fine fiber pulp that meets the particle size requirements passes through the filter screen 15 and accumulates at the bottom of the settling tank 14, which can be discharged at any time by opening the discharge valve 16. Larger, insufficiently crushed fiber clumps are trapped at the top by the filter screen 15. To achieve efficient resource utilization, a pusher plate 18 is slidably installed at the top of the settling tank 14, which is in contact with the surface of the filter screen 15. When a certain amount of uncrushed fiber clumps accumulates... After the coarse material passes through, the controller 5 starts the motor 20, which drives the screw 19 to rotate and moves the pusher plate 18 to the left along the filter screen 15, pushing the intercepted material into the return frame 17. The coarse material falling into the return frame 17 will gradually accumulate above the return plate 22. Then, the controller 5 controls the electric guide rail 21 to drive the return plate 22 to rise, lift the material and send it back into the conveyor frame 1. Finally, the screw conveyor 3 realizes the recycling and re-crushing, ensuring that all the cardboard is finally converted into qualified pulp and improving the raw material utilization rate.
