[0030] The working principle of the adhesive removing device for waste paper recycling pulping provided by the utility model is as follows:

[0031] The floatation process is as follows:

[0032] The waste paper pulp first enters the floatation device 4, in which, by injecting micro-bubbles into the pulp, the bubbles will adhere to the light components containing adhesive, and due to the buoyancy of the bubbles, the light components containing adhesive will be floated and rise to the top of the floatation device 4; the top of the floatation device 4 is provided with a scraper or similar device for collecting the floated adhesive and discharging it out of the system, thereby realizing the preliminary separation of the light components and the fibers;

[0033] The conical slag removing process is as follows:

[0034] The pulp after the floatation preliminary treatment enters the conical slag remover 7, which utilizes the principles of gravity settling and centrifugal separation to further remove the heavier adhesive particles in the pulp; in the conical slag remover 7, the pulp gradually slows down and settles along the conical inner wall, the heavier adhesive particles will deposit at the bottom of the cone due to the inertia effect, while the lighter fibers continue to flow upwards; by adjusting the cone angle and flow rate of the conical slag remover 7, the separation effect can be optimized to ensure that as many adhesives as possible are removed.

[0035] Cationic decontamination process:

[0036] The slurry treated by the conical decontaminator 7 enters the cationic decontaminator 9, which effectively removes the dissolved or colloidal state of the adhesive by using the principle of charge adsorption. In the cationic decontaminator 9, the slurry passes through a filter layer with cation exchange resin or similar materials, which can adsorb negatively charged adhesive molecules, thereby achieving further separation of adhesive and fiber. Then, the pump body 21 extracts the slurry, and a filter is installed at the communication between the cationic decontaminator 9 and the pump body 21. When the pump body 21 extracts the slurry, the filter blocks the adhesive in the cationic decontaminator 9;

[0037] Backflow and pushing process:

[0038] After the adhesive is removed, the remaining slurry flows into the collection bin 8 through the first discharge port 19 and the second discharge port 20, and then flows to the driving rotating wheel 11 along the inclined direction of the collection bin 8. In the process of flowing, large particle adhesives are blocked by the filter plate 10 and cannot pass through. The motor 18 fixedly connected to the top of the supporting table 17 is started, and the motor 18 drives the driving rotating wheel 11 rotatingly connected inside the collection bin 8 to rotate intermittently. The single rotation angle of the driving rotating wheel 11 is seven hundred and twenty degrees. The driving rotating wheel 11 drives the driven rotating wheel 12 to rotate through the transmission belt 13. The transmission belt 13 moves intermittently along the rotation direction of the driving rotating wheel 11 with the rotation of the driving rotating wheel 11 and the driven rotating wheel 12. The transmission belt 13 drives the slurry taking bin 14 to move synchronously. The slurry taking bin 14 is filled with slurry from the collection bin 8 with the intermittent movement of the transmission belt 13, and then rises to the top of the transmission belt 13 and moves to one side of the second feeding port 6. At this time, the motor 18 stops rotating, and the electric push rod 15 is started. The electric push rod 15 drives the L-shaped push rod 16 to move to the right, and the L-shaped push rod 16 pushes the bottom of the slurry taking bin 14 to the right to make the slurry taking bin 14 inclined, and then the slurry in the slurry taking bin 14 is poured into the second feeding port 6. The slurry is subjected to the second adhesive removal process. The electric push rod 15 drives the L-shaped rod to reset, and the motor 18 drives the driving rotating wheel 11 to rotate again. When the next slurry taking bin 14 moves to one side of the second feeding port 6, the motor 18 stops rotating again, and the electric push rod 15 is started. The above process is repeated.

[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
