Description

Technical Field

[0001] This utility model relates to the technical field of waste currency processing, and in particular to a waste currency pulping and degumming device. Background Technology

[0002] When recycling waste banknotes, pulping is required. The adhesive residue on the banknotes can negatively impact the quality of the pulp, necessitating de-adhesion treatment. A paper pulp adhesive removal system, disclosed in Chinese invention patent application CN119800756A, includes a housing with a rotatably connected cylindrical rod. A screw conveyor is installed on a portion of the cylindrical rod. A motor drives the cylindrical rod to rotate, which in turn drives multiple sets of scrapers. This system performs centrifugal screening of the pulp, removing the adhesive residue, while simultaneously scraping off substances adhering to the curved screen. This prevents substances from adhering to the screen, resulting in relatively good screening efficiency. Furthermore, the separation of the threaded sleeve from the cylindrical rod allows for easy removal of the sleeve and scrapers, facilitating individual maintenance.

[0003] However, the aforementioned adhesive removal system did not rub the fiber sheets containing adhesive in the pulp, resulting in the fiber sheets containing adhesive being in the same state as those without adhesive, leading to poor removal and separation effects. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a waste banknote pulping and degumming device that improves the removal and separation effect of adhesives by kneading the waste banknote pulp and changing the state of the fiber sheets of the adhesive.

[0005] This utility model discloses a waste currency pulping and degumming device, comprising an outer cylinder and a drain pipe. The outer cylinder has an internal chamber I, and the drain pipe is installed at the bottom of the outer cylinder, communicating with the pulping chamber. It also includes a feed hopper, an inner cylinder, a vertical shaft, a first bevel gear, a motor, and a second bevel gear. The feed hopper is installed on the upper edge of the outer cylinder and communicates with the first chamber. The inner cylinder is rotatably installed within the first chamber of the outer cylinder, and a second chamber is located inside the inner cylinder. A first gap is formed between the outer wall of the inner cylinder and the inner wall of the outer cylinder, gradually narrowing from top to bottom. A second gap is formed between the bottom of the inner cylinder and the bottom of the outer cylinder. The bottom of the inner cylinder has a pulping inlet hole communicating with both the first and second chambers. The vertical shaft is rotatably mounted on a bracket on the outer cylinder, with its lower end connected to the inner cylinder via a transmission connection. A first bevel gear is installed on the upper end of the first bevel gear. The motor is mounted on a bracket on the outer cylinder, and the second bevel gear is rotatably mounted on a bracket on the outer cylinder. The output shaft of the motor is connected to the second bevel gear via a transmission connection. Connection; During operation, the motor drives the second bevel gear to rotate, which meshes with the first bevel gear to drive the vertical shaft to rotate. The vertical shaft drives the inner cylinder to rotate. Waste banknote slurry is added to the gap one between the outer and inner cylinders through the feed hopper, causing the waste banknote slurry to flow along the gap one to the gap two, and enter the inner cylinder's chamber two through the slurry inlet hole. During the flow of the slurry along the gap one, the relatively rotating inner and outer cylinders knead the fiber sheets in the slurry. Fiber sheets containing adhesive are kneaded into small balls after some fibers are removed, while fiber sheets without adhesive do not form small balls. The kneaded slurry undergoes adhesive removal and separation in the inner cylinder's chamber two. After adhesive removal and separation, the valve of the drain pipe is opened, allowing the waste banknote slurry to be discharged through the inner cylinder's slurry inlet hole and drain pipe. Compared with existing technologies, by kneading the waste banknote slurry, the fiber sheets containing adhesive are in different states from those without adhesive, thus improving the adhesive removal and separation effect.

[0006] Preferably, it also includes a shaft tube, a bevel gear three, and multiple stirring blades. The shaft tube is rotatably mounted on the outside of the vertical shaft. The upper end of the shaft tube is equipped with bevel gear three, which meshes with bevel gear two. Multiple stirring blades are installed on the outer wall of the shaft tube. The motor drives bevel gear two to rotate, and bevel gear two meshes with bevel gear three to drive the shaft tube to rotate. The shaft tube rotates in the opposite direction to the vertical shaft, so that the shaft tube drives multiple stirring blades to stir and slurry the slurry in the inner cylinder chamber two.

[0007] Preferably, it also includes air holes and aeration heads. A hollow air delivery channel is provided inside the vertical shaft, an air inlet is provided at the upper end of the vertical shaft, and air holes are provided on the bottom outer wall of the vertical shaft. The aeration head is installed at the lower end of the shaft tube, and the air holes are located inside the aeration head. The air inlet at the upper end of the vertical shaft is connected to an external aeration and air delivery system, so that the gas used for aeration is delivered downward through the hollow air delivery channel of the vertical shaft and input into the aeration head through the air holes. Microbubbles are delivered into the waste banknote slurry through multiple aeration holes of the aeration head, so that the waste banknote slurry is aerated. The adhesives in the waste banknote slurry adsorb a large number of microbubbles to form clumps. The clumps float up, realizing the separation of the adhesives from the slurry. The clumps are floated out, realizing the removal of adhesives.

[0008] Preferably, it also includes a rotary joint, which is installed on the upper air inlet of the vertical shaft; the external aeration and air delivery system is connected to the vertical shaft through the rotary joint, so that the pipeline will not twist when the vertical shaft rotates.

[0009] Preferably, it also includes a collection trough and a slag discharge trough. The collection trough is installed on a bracket on the outer cylinder and is arranged around the upper outer side of the inner cylinder. The slag discharge trough is installed on the collection trough. After the clumps floated by aeration are removed from the inner cylinder, they flow into the collection trough and are discharged through the collection trough.

[0010] Preferably, it also includes multiple arc-shaped baffles, which are evenly installed on the outer wall of the shaft tube. The upper edges of the multiple arc-shaped baffles are higher than the upper edge of the inner cylinder, and the lower edges of the multiple arc-shaped baffles are lower than the lower edge of the inner cylinder. When the shaft tube rotates, it drives the multiple arc-shaped baffles to rotate. The multiple arc-shaped baffles push the aeration blocks into the collection tank, discharge the aeration blocks into the collection tank, and discharge them through the slag discharge tank.

[0011] Preferably, it also includes a plug, a bottom rod, and a pusher cylinder. A slag discharge hole is provided at the bottom of the inner cylinder. The plug is inserted into the slag discharge hole of the inner cylinder. The bottom rod is installed at the lower end of the plug. The fixed end of the pusher cylinder is installed on the lower end face of the outer cylinder. The piston rod of the pusher cylinder extends into the bottom of the first chamber of the outer cylinder. The pusher cylinder is aligned with the bottom rod. A shaft seal assembly is provided between the piston rod of the pusher cylinder and the bottom wall of the outer cylinder. After the waste slurry in the second chamber of the inner cylinder is discharged through the slurry inlet and the liquid outlet pipe, the inner cylinder is rotated so that the bottom rod is aligned with the piston rod of the pusher cylinder. The piston rod of the pusher cylinder extends upward, so that the piston rod of the pusher cylinder pushes the bottom rod and the plug upward, so that the plug opens the slag discharge hole of the inner cylinder, allowing the residue in the inner cylinder to be discharged through the slag discharge hole and the liquid outlet pipe. After the slag discharge is completed, the piston rod of the pusher cylinder retracts and resets, and the plug and the bottom rod descend and reset, so that the plug blocks the slag discharge hole of the inner cylinder again. In order for the plug to be able to automatically reset, the plug can be elastically installed on the inner cylinder.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, a waste currency pulping and degumming device includes an outer cylinder 1 and a drain pipe 2. The outer cylinder 1 has an internal chamber 1, and the drain pipe 2 is installed at the bottom of the outer cylinder 1, communicating with the pulping chamber. It also includes a feed hopper 3, an inner cylinder 4, a vertical shaft 5, a first bevel gear 6, a motor 7, and a second bevel gear 8. The feed hopper 3 is installed on the upper edge of the outer cylinder 1 and communicates with the first chamber of the outer cylinder 1. The inner cylinder 4 is rotatably installed in the first chamber of the outer cylinder 1. The inner cylinder 4 has an internal chamber 2. A gap 1 is provided between the outer wall of the inner cylinder 4 and the inner wall of the outer cylinder 1, and this gap 1 gradually narrows from top to bottom. A gap 2 is provided between the bottom of the inner cylinder 4 and the bottom of the outer cylinder 1. The bottom of the inner cylinder 4 has a pulp inlet hole communicating with both the second and first chambers. The vertical shaft 5 is rotatably mounted on a bracket on the outer cylinder 1. The lower end of the vertical shaft 5 is connected to the inner cylinder 4 via a transmission. The upper end of the bevel gear 6 is mounted on the bevel gear 6. The motor 7 is mounted on a bracket on the outer cylinder 1. The bevel gear 8 is rotatably mounted on a bracket on the outer cylinder 1. The output shaft of the motor 7 is connected to the bevel gear 8 via a transmission. The system also includes a plunger 17, a bottom rod 18, and a push cylinder 19. The bottom of the inner cylinder 4 is provided with a slag discharge hole. The plunger 17 is inserted into the slag discharge hole of the inner cylinder 4. The lower end of the plunger 17 is mounted on the bottom rod 18. The fixed end of the push cylinder 19 is mounted on the lower end face of the outer cylinder 1. The piston rod of the push cylinder 19 extends into the bottom of the chamber of the outer cylinder 1. The push cylinder 19 is aligned with the bottom rod 18. A shaft seal assembly is provided between the piston rod of the push cylinder 19 and the bottom wall of the outer cylinder 1.

[0023] During operation, motor 7 drives bevel gear 2 8 to rotate. Bevel gear 2 8 meshes with bevel gear 1 6 to drive vertical shaft 5 to rotate. Vertical shaft 5 drives inner cylinder 4 to rotate. Waste coin slurry is added through feed hopper 3 into gap 1 between outer cylinder 1 and inner cylinder 4, causing the waste coin slurry to flow along gap 1 to gap 2 and enter chamber 2 of inner cylinder 4 through slurry inlet. During the flow of slurry along gap 1, the relatively rotating inner cylinder 4 and outer cylinder 1 knead the fiber sheets in the slurry. Fiber sheets containing adhesive are kneaded into small balls after some fibers are removed, while fiber sheets without adhesive do not form small balls. The kneaded slurry undergoes adhesive removal and separation in chamber 2 of inner cylinder 4. After adhesive removal and separation, the valve of drain pipe 2 is opened, allowing the waste coin slurry to pass through the inner cylinder. The slurry inlet hole and the liquid outlet pipe 2 of the inner cylinder 4 are discharged. The inner cylinder 4 is rotated so that the bottom rod 18 is aligned with the piston rod of the push cylinder 19. The piston rod of the push cylinder 19 extends upward, so that the piston rod of the push cylinder 19 pushes the bottom rod 18 and the plug 17 upward, so that the plug 17 opens the slag discharge hole of the inner cylinder 4, so that the residue in the inner cylinder 4 is discharged through the slag discharge hole and the liquid outlet pipe 2. After the slag discharge is completed, the piston rod of the push cylinder 19 retracts and resets, and the plug 17 and the bottom rod 18 descend and reset, so that the plug 17 blocks the slag discharge hole of the inner cylinder 4 again. In order to enable the plug 17 to automatically reset, the plug 17 can be elastically installed on the inner cylinder 4. Compared with the existing technology, by kneading the waste coin slurry, the fiber sheets containing adhesives are in different states from those without adhesives, thereby improving the removal and separation effect of adhesives. Example 2

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, based on Embodiment 1, it further includes a shaft tube 9, a bevel gear 10, and multiple stirring blades 11. The shaft tube 9 is rotatably mounted on the outside of the vertical shaft 5. The bevel gear 10 is installed at the upper end of the shaft tube 9, and the bevel gear 10 meshes with the bevel gear 8. Multiple stirring blades 11 are installed on the outer wall of the shaft tube 9. It also includes air holes 12 and aeration heads 13. A hollow air delivery channel is provided inside the vertical shaft 5. An air inlet is provided at the upper end of the vertical shaft 5. Air holes 12 are provided on the bottom outer wall of the vertical shaft 5. The aeration heads 13 are installed at the lower end of the shaft tube 9, and the air holes 12 are located at the lower end of the aeration heads 13. The interior also includes a rotary joint 20, which is installed on the upper air inlet of the vertical shaft 5; it also includes a collection trough 14 and a slag discharge trough 15, the collection trough 14 is installed on a bracket on the outer cylinder 1, the collection trough 14 is arranged around the upper outer side of the inner cylinder 4, and the slag discharge trough 15 is installed on the collection trough 14; it also includes multiple arc-shaped baffles 16, which are evenly installed on the outer wall of the shaft tube 9, the upper edge of the multiple arc-shaped baffles 16 is higher than the upper edge of the inner cylinder 4, and the lower edge of the multiple arc-shaped baffles 16 is lower than the lower edge of the inner cylinder 4.

[0025] The external aeration and air delivery system is connected to the vertical shaft 5 via a rotary joint 20, ensuring that the pipeline does not twist when the vertical shaft 5 rotates. The motor 7 drives the second bevel gear 8 to rotate, and the second bevel gear 8 meshes with the third bevel gear 10 to drive the shaft tube 9 to rotate. The shaft tube 9 rotates in the opposite direction to the vertical shaft 5, causing the shaft tube 9 to drive multiple stirring blades 11 to stir and slurry the slurry in the second chamber of the inner cylinder 4. The gas used for aeration is delivered downward through the hollow air delivery channel of the vertical shaft 5 and input into the aeration head 13 through the air hole 12. Microbubbles are delivered into the waste banknote slurry through multiple aeration holes of the aeration head 13, aerating the waste banknote slurry. This causes the adhesive in the waste banknote slurry to adsorb a large number of microbubbles and form clumps. The clumps float up, and when the shaft tube 9 rotates, it drives multiple arc-shaped baffles 16 to rotate. The multiple arc-shaped baffles 16 push the aerated clumps into the collection tank 14, discharging the aerated clumps into the collection tank 14 and then discharging them through the slag discharge tank 15, thus achieving the separation of adhesive and slurry.

[0026] like Figures 1 to 7 As shown, this utility model discloses a waste currency pulping and degumming device. During operation, motor 7 first drives bevel gear 8 to rotate. Bevel gear 8 meshes with bevel gear 6, driving vertical shaft 5 to rotate. Vertical shaft 5 drives inner cylinder 4 to rotate. Waste currency pulp is then added through feed hopper 3 into gap 1 between outer cylinder 1 and inner cylinder 4, causing the pulp to flow along gap 1 to gap 2 and enter chamber 2 of inner cylinder 4 through inlet hole. During the flow of pulp along gap 1, the relatively rotating inner cylinder 4 and outer cylinder 1 knead the fiber sheets in the pulp. Fiber sheets containing adhesive are kneaded into small clumps after some fibers are removed, while fiber sheets without adhesive do not form clumps. The kneaded pulp remains in chamber 2 of inner cylinder 4. Then, motor 7 drives bevel gear 8 to rotate, and bevel gear 8 meshes with bevel gear 6. The shaft tube 9 rotates, and the shaft tube 9 rotates in the opposite direction to the vertical shaft 5. This causes the shaft tube 9 to drive multiple stirring blades 11 to stir and slurry the slurry in the second chamber of the inner cylinder 4. The gas for aeration is delivered downward through the hollow air delivery channel of the vertical shaft 5 and input into the aeration head 13 through the air hole 12. Microbubbles are then delivered into the waste coin slurry through multiple aeration holes of the aeration head 13, causing the waste coin slurry to be aerated. This causes the adhesive substances in the waste coin slurry to adsorb a large number of microbubbles and form clumps. The clumps float up, and multiple arc-shaped baffles 16 push the aerated clumps into the collection tank 14, discharging them into the collection tank 14 and then through the slag discharge tank 15. This removes and separates the adhesive substances. Finally, after the removal and separation of the adhesive substances is completed, the valve of the drain pipe 2 is opened, allowing the waste coin slurry to be discharged through the slurry inlet of the inner cylinder 4 and the drain pipe 2.

[0027] The main functions achieved by this utility model are:

[0028] 1. By kneading the waste coin slurry, the fiber sheets containing adhesives are in different states from those without adhesives, thereby improving the removal and separation of adhesives.

[0029] 2. It can stir and pulp the slurry in chamber two of the inner cylinder 4;
