[0019] According to an embodiment of the present invention, a paper-plastic separator is provided.

[0020] Example 1 like Figure 1-4As shown, a paper-plastic separator according to an embodiment of the present invention includes a separator tank 1. A first pneumatic butterfly valve 2 is fixedly connected to the bottom left side of the separator tank 1. A recycling door panel 3 is connected to the outer right side of the separator tank 1 via a hinge. A first servo motor 4 is fixedly connected to the top center of the separator tank 1. A separator 5 is fixedly connected to the output shaft of the first servo motor 4. The separator 5 is disposed inside the separator tank 1. A pre-kneading tank 6 is fixedly connected to the top left side of the separator tank 1, and a water storage tank 7 is fixedly connected to the top right side of the separator tank 1. The pre-kneading tank 6 includes a tank body 8 and a second servo motor 9. The first servo motor 9 and the second servo motor 9 are symmetrically mounted on the top of the tank body 8. A rotating cylinder 10 is symmetrically connected inside the tank body 8. Protrusions 11 are equidistantly connected to the outer wall of the rotating cylinder 10. A second pneumatic butterfly valve 12 is symmetrically connected to the bottom of the tank body 8. The output shafts of the second servo motors 9 extend into the tank body 8, and their bottom ends are fixedly connected to the top of the rotating cylinder 10. The tank body 8 is fixedly connected to the interior of the tank body 8 through the second pneumatic butterfly valve 12. A feed inlet is connected through the left side of the outer wall of the tank 8, allowing the paper and plastic fragments to be processed to be fed into the tank body 8. Then, liquid is injected into the tank 8, and the second servo motors 9 are started respectively. The output shafts of the two second servo motors 9 rotate at different times, and the output shafts of the relatively rotating second servo motors 9 drive the rotating drum 10 to rotate relative to each other. This allows the rotating drum 10 to agitate the liquid and the mixed paper-plastic fragments to simulate a kneading action. The two rotating drums 10 rotating in opposite directions will generate strong shearing, squeezing and tearing forces at the gap. When the material is sucked into the roller gap, it will undergo violent kneading, crushing and tearing. The resulting hydraulic vortex and collision friction are more direct, more concentrated and stronger, which can more effectively destroy the bonding force between the paper fibers and the plastic film. The material will be forced through the gap of the rotating drum 10, ensuring that each piece of material is subjected to relatively uniform and strong mechanical action, which may reduce dead corners or insufficient processing. The rotating drums 10 with one fast and one slow speed can enhance the shearing and kneading effect, which can pre-treat the material before it enters the hydraulic vortex environment for dispersion and size screening and separation. It can take advantage of its peeling effect and avoid the risk of clogging in the hydraulic separation environment.

The spray heads 19 are located between the rotating cylinders 10. A water injection pipe is provided on the right side of the outer wall of the liquid tank 13 to inject liquid into the liquid tank 13. Then, the liquid can be pumped to the water supply pipe 18 by the liquid pump 15. Then, the liquid is injected into the tank body 8 through the spray heads 19 on the outer wall of the water supply pipe 18. This can increase the liquid volume inside the tank body 8 in real time during the pretreatment process. After the tank body 8 is emptied, the outer wall of the rotating cylinder 10 can be flushed and cleaned, further improving its practicality.

The first servo motor 4 is started. The output of the first servo motor 4... The shaft drives the first connecting shaft 20 and the second connecting shaft 21 to rotate. The arc-shaped blades 24 on the outer walls of the first connecting shaft 20 and the second connecting shaft 21 rotate at high speed. The high-speed rotating arc-shaped blades 24 generate strong hydraulic vortices and mechanical shearing forces. Under the impact of high-speed water flow, direct impact of blades, and intense friction, collision, and kneading between materials, between materials and the tank wall, and between materials and the isolation mesh 23, the paper-plastic composite sheet is continuously torn and kneaded. Under the mechanical and hydraulic action, the moist pulp fiber layer gradually peels off from the plastic and aluminum foil matrix, breaks down, dissolves, and disperses into the water, forming a pulp suspension. The fine pulp fibers that are peeled off... As water flows through the isolation screen 23 installed on the inner wall of the separator 1, the peeled plastic sheets and aluminum foil sheets, as well as larger composite fragments that are not fully peeled, are blocked inside the screen by the isolation screen 23. The aqueous suspension containing pulp fibers is discharged by the first pneumatic butterfly valve 2 after passing through the isolation screen 23. The double-layer isolation screen 23 can fully recover and filter the plastic that is not separated or is generated by separation. The scraper 25 at the bottom of the arc blade 24 scrapes the isolation screen 23.

Then, liquid is injected into the tank 8, and then the second servo motors 9 are started respectively. The output shafts of the two second servo motors 9 rotate differently, and the output shafts of the relatively rotating second servo motors 9 drive the rotating drum 10 to rotate relative to each other. This allows the rotating drum 10 to stir the liquid and the mixed paper-plastic fragments to simulate a kneading action. The two rotating drums 10 rotating in opposite directions will generate strong shearing force, squeezing force and tearing force at the gap. When the material is sucked into the roller gap, it will undergo violent kneading, crushing and tearing. The resulting hydraulic vortex and collision friction are more direct, more concentrated and stronger, which can more effectively destroy the bonding force between the paper fiber and the plastic film. The pre-treated material is put into the separation tank 1 through the first pneumatic butterfly valve 2, and the first servo motor 4 is started. The output of the first servo motor 4... The shaft drives the first connecting shaft 20 and the second connecting shaft 21 to rotate. The arc-shaped blades 24 on the outer walls of the first connecting shaft 20 and the second connecting shaft 21 rotate at high speed. The high-speed rotating arc-shaped blades 24 generate strong hydraulic vortices and mechanical shearing forces. Under the impact of high-speed water flow, direct impact of blades, and intense friction, collision, and kneading between materials, between materials and the tank wall, and between materials and the isolation screen 23, the paper-plastic composite sheet is continuously torn and kneaded. Under the mechanical and hydraulic action, the wet pulp fiber layer is gradually peeled off from the plastic and aluminum foil matrix, broken up, dissolved, and dispersed into the water to form a pulp suspension. The small pulp fibers that are peeled off pass through the isolation screen 23 installed on the inner wall of the separation tank 1 with the water flow. The peeled plastic sheets and aluminum foil sheets, as well as larger composite fragments that are not fully peeled off, are blocked by the isolation screen 23 on the inside of the screen. The water suspension containing pulp fibers is discharged by the first pneumatic butterfly valve 2 after passing through the isolation screen 23.
