Description

Technical Field

[0001] The present invention relates to the technical field of solid waste recycling and treatment, and specifically relates to an environmentally friendly recycling and reproduction treatment system for packaging boxes. Background Art

[0002] In life, the inventory of common packaging boxes is very large, and the consumption is also very large. In order to reduce the environmental pollution caused by landfilling and incinerating packaging boxes other than paper materials, usually, environmentally friendly recycling and reproduction are carried out on plastic or composite material packaging boxes. By promoting degradable materials and recycled pulp technology, the packaging boxes can be recycled into new items to extend the life cycle of resources, reduce the waste of packaging materials, and enhance the environmental awareness of the whole people.

[0003] However, when the existing environmentally friendly recycling and reproduction treatment system for packaging boxes pre-treats the packaging boxes, it usually squeezes the packaging boxes and then classifies them. When squeezing some packaging boxes of liquid food, the residues inside are easily squeezed out, and the squeezed contents cannot be well collected and are easy to flow out of the device. After a long time, bacteria are easily bred and odors are generated, which is not environmentally friendly; secondly, during the process of shredding the packaging boxes, due to the different sizes of the packaging boxes, the sizes of the generated fragments are significantly different. In addition, the shredding equipment is horizontal and relatively long, so that the fragments are easily retained in the shredding equipment, affecting the shredding effect of the shredding equipment, and at the same time, it is easy to cause the fragments to flow into the subsequent processes at a slower speed; in addition, the original pulp regenerated after the packaging boxes are shredded and cooked will accumulate on the top of the treatment tank. If it is not pushed out in time, the original pulp is likely to sink and squeeze and mix the waste at the bottom of the treatment tank, which is not conducive to the discharging of the regenerated original pulp.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The environmentally friendly recycling and processing system for packaging boxes, through the provided squeezing roller, conveyor mesh belt, mesh tube and first nozzle, enables the packaging boxes to be squeezed again before the crushing step, and the squeezed contents will flow into the processing pool, and at the same time, the stains on the surface of the packaging boxes and the squeezed contents can also be washed by the water flow sprayed from the first nozzle on the mesh tube, so that the residues on the inner and outer surfaces of the packaging boxes can be washed into the purification pool along the conveyor mesh belt for sterilization and deodorization, thereby reducing the breeding of bacteria and the generation of odors, which is more environmentally friendly.

[0016] 2. The environmentally friendly recycling and processing system for packaging boxes, through the provision of the second water pipe, the second nozzle and the discharge hopper, ensures that after the packaging boxes are crushed, the fragments of different sizes retained in the crusher can be rushed to the bottom of the annular cavity of the crusher under the action of the high-pressure water flow from the second nozzle, and flow along the annular cavity to the discharge hopper, thereby reducing the retention of the fragments of the packaging boxes after they are crushed in the crusher, reducing the adverse effects of the retained fragments on the crushing effect of the crusher, and at the same time helping to speed up the speed at which the fragments enter the subsequent processes.

When the pulp in the processing tank is cooked and floats to the top of the liquid surface in the processing tank, the third motor will drive the rotating rod to rotate so that the screen is perpendicular to the liquid surface of the processing tank. At the same time, the screen will also contact the original pulp on the top of the liquid surface. Then, the slide plate will push the regenerated original pulp accumulated on the top of the liquid surface into the screen under the drive of the linear guide rail, so that the original pulp can be fished out of the processing tank in time to reduce the squeezing and mixing of the original pulp on the waste at the bottom of the processing tank, thereby making it more conducive to the discharge of the regenerated original pulp.

[0023] As Figures 1 to 7As shown in the figure, the environmentally friendly circular reproduction processing system of the packaging box in this embodiment includes a bottom box 1. The bottom box 1 is provided with an opening connected to the bottom of the feeding hopper 2, so that the packaging box that has completed the extrusion action can smoothly fall into the bottom box 1. At the same time, the residues extruded from the packaging box can enter the purification pool 25 at the inner bottom of the bottom box 1, facilitating the collection of the contents extruded from the packaging box. On one side of the top of the bottom box 1, there is a feeding hopper 2. At the bottom inside the feeding hopper 2, there are two extrusion rollers 3. The surfaces of the extrusion rollers 3 are smooth and the distance between them is relatively close, enabling the packaging box to be extruded into a flat shape, thus facilitating the extrusion of the residues inside the packaging box. On one side wall of the feeding hopper 2, there is an electromechanical box 4. The function of the electromechanical box 4 is to protect the spur gear 35 and the sprocket mechanism 36 for subsequent maintenance. On one side wall of the electromechanical box 4, a first motor 5 is installed. The first motor 5 is a rotating motor that can drive one of the extrusion rollers 3 to rotate actively. On the other side of the top of the bottom box 1, a first water pipe 6 penetrates. The function of the first water pipe 6 is to introduce circulating water for flushing the packaging box into the bottom box 1, so that the residues squeezed on the surface of the packaging box can be flushed by the circulating water, thereby reducing the residues on the surface of the packaging box, which is beneficial to reducing the subsequent shredding and reproduction of the packaging box. The bottom end of the first water pipe 6 is sleeved with a mesh pipe 23. The mesh pipe 23 is located above the conveyor belt 22 and can direct the water flow towards the surface of the packaging box on the top of the conveyor belt 22, thus realizing the flushing of the surface of the packaging box. At the bottom end of the mesh pipe 23, a first nozzle 24 is installed. The function of the first nozzle 24 is to atomize the water flow, making it easier to wash away the residues and stains on the surface of the packaging box, thus facilitating the cleaning of the surface of the packaging box. Inside the top of the bottom box 1, there is a conveyor belt 22. The conveyor belt 22 can allow water to pass through, so that the wastewater generated by the flushing can smoothly flow into the purification pool 25 of the bottom box 1, realizing the collection of the contents extruded from the packaging box and the collection of the wastewater generated during the cleaning process of the packaging box, reducing the pollution to the environment during the circular reproduction process of the packaging box and making the entire circular reproduction process more environmentally friendly. At the bottom of the conveyor belt 22, there is a purification pool 25. Inside the purification pool 25, there is also a treatment structure for treating wastewater, bacteria, and odors, which can effectively kill the bacteria in the purification pool 25 and eliminate the odors. On one side of the bottom box 1, there is a shredder 11. Inside the shredder 11, there is an annular cavity, so that the water flow ejected by the second nozzle 26 can flow along the bottom of the annular cavity and wash the retained packaging box fragments into the discharge hopper 30. At the top of the shredder 11, a second water pipe 12 penetrates. The function of the second water pipe 12 is to introduce circulating water into the inside of the shredder 11, so that the circulating water can wash the inside of the shredder 11 to reduce the residue of the packaging box fragments in the shredder 11. At the bottom end of the second water pipe 12, there are multiple second nozzles 26. The water outlet of the second nozzle 26 is inclined towards the top of the fixed blade 27, so that the ejected water flow can wash the fixed blade 27 and the rotating blade 28 in real time, reducing the probability of fragments getting stuck between the rotating blade 28 and the fixed blade 27.Furthermore, the probability of the blender 11 getting stuck is reduced, which is conducive to improving the shredding efficiency of the blender 11. A viewing window 9 is provided on the front surface of the bottom box 1. The function of the viewing window 9 is to facilitate the operator to view the state of the washing of the packaging boxes in the bottom box 1 in real time, which is beneficial to the cleaning of the packaging boxes. Multiple groups of fixed blades 27 are arranged inside the blender 11. Rotating blades 28 are provided on both side walls of the fixed blades 27. The fixed blades 27 are fixed inside the blender 11, and the rotating blades 28 rotate along the two side walls of the fixed blades 27, capable of shredding the packaging boxes entering the blender 11. A discharge hopper 30 penetrates through the bottom of one side wall of the blender 11. The discharge port of the discharge hopper 30 is arranged obliquely downward, so that the flushed water flow can carry the packaging box fragments and quickly fall into the treatment tank 14 for subsequent treatment, reducing the amount of packaging box fragments remaining in the blender 11. A treatment tank 14 is arranged at the bottom of the discharge hopper 30. The function of the treatment tank 14 is to steam the packaging box fragments to accelerate the separation of different materials on the packaging box fragments, which is beneficial to the subsequent reproduction of the packaging box fragments. Linear guide rails 15 are installed on both side walls of the treatment tank 14. The function of the linear guide rails 15 is to control the movement of the sliding plate 16 along the treatment tank 14, thereby realizing the movement of the position of the screening net 20, and further being beneficial to the screening net 20 to push the raw pulp accumulated on the top of the liquid level of the treatment tank 14. The top of the linear guide rail 15 is slidably connected with a sliding plate 16. A rotating rod 18 is arranged on the top of the sliding plate 16. The function of the rotating rod 18 is to drive the screening net 20 to rotate, so that when the sliding plate 16 slides back, it does not contact the liquid level of the treatment tank 14, thereby reducing the backward push of the screening net 20 on the raw pulp in the treatment tank 14. A clamping cylinder 19 is fixedly connected to the middle of the rotating rod 18. The function of the clamping cylinder 19 is to realize the stable connection between the screening net 20 and the rotating rod 18, and at the same time facilitate the removal of the screening net 20 from the clamping cylinder 19. The screening net 20 is arranged at the bottom of the clamping cylinder 19. The function of the screening net 20 is to capture and push the raw pulp floating to the top of the treatment tank 14, which is beneficial to realizing the rapid pushing out of the raw pulp from the treatment tank 14. A draining hopper 32 is arranged at the end of the treatment tank 14. The function of the draining hopper 32 is to quickly drain the water from the pushed-out raw pulp, which is beneficial to the subsequent reproduction steps of the raw pulp. A sieve mesh 21 is arranged on the top of the draining hopper 32. The mesh number of the sieve mesh 21 is fifty meshes, which can preliminarily dehydrate the raw pulp.

[0024] Specifically, positive gears 35 are arranged at one shaft end of each of the two extrusion rollers 3. The two positive gears 35 are meshed with each other. The shaft end of one of the extrusion rollers 3 is connected to the shaft end of the first motor 5 outside the electrical box 4, so that one of the actively rotating positive gears 35 can mesh with the other positive gear 35 to rotate, thereby realizing the meshing rotation of the two positive gears 35, enabling the two extrusion rollers 3 to rotate towards each other, and further realizing the extrusion of the packaging boxes, which is beneficial to extruding the residues in the packaging boxes.

[0025] Further, a sprocket mechanism 36 is provided at the shaft end of one of the extrusion rollers 3. The shaft end of the drive roller at the end of the conveyor mesh belt 22 is connected to the sprocket of the sprocket mechanism 36. The conveyor mesh belt 22 is rotationally connected to the bottom box 1 through the sprocket mechanism 36. The function of the conveyor mesh belt 22 is to convey the extruded packaging boxes and at the same time enable the wastewater generated during the cleaning process to flow into the purification tank 25 for treatment, making the recycling process of the packaging boxes more environmentally friendly.

[0026] Further, a first waste liquid pipe 7 penetrates through the bottom of the other side wall of the bottom box 1. A solenoid valve 8 is installed at the end of the first waste liquid pipe 7. The first waste liquid pipe 7 communicates with the inside of the purification tank 25. The first waste liquid pipe 7 can discharge the treated wastewater to prevent the water level in the purification tank 25 from being too high and affecting the operation of the conveyor mesh belt 22, and at the same time facilitate the re-treatment of the treated wastewater to achieve the recycling of water resources.

[0027] Further, a connecting hopper 10 is provided at the top of one side wall of the shredder 11. The connecting hopper 10 communicates with the inside of the bottom box 1. The end of the conveyor mesh belt 22 is located inside the connecting hopper 10. The connecting hopper 10 can receive the packaging boxes conveyed by the conveyor mesh belt 22, enabling the extruded and cleaned packaging boxes to enter the shredder 11 for the shredding step.

[0028] Further, a second motor 13 is installed on the front of the shredder 11. The output end of the second motor 13 is connected to a rotating shaft 29. The rotating blade 28 is snap-connected to the rotating shaft 29. The rotating blade 28 is rotationally connected to the fixed blade 27 through the rotating shaft 29, enabling the rotating blade 28 to rotate along the side wall of the fixed blade 27, so that the packaging boxes can be driven by the rotating blade 28 to be shredded, realizing the shredding of the packaging boxes.

[0029] Further, a third motor 17 is installed at the top of one side wall of one of the sliding plates 16. The output end of the third motor 17 is connected to one end of a rotating rod 18. The rotating rod 18 is rotationally connected to the sliding plate 16 through the third motor 17. The third motor 17 can drive the rotating rod 18 to rotate, causing the rotating rod 18 to drive the dial net 20 to rotate from the vertically downward state to the vertically upward state, so that the dial net 20 does not contact the top surface of the liquid in the treatment tank 14 during the return sliding process, thereby reducing the interference with the original pulp on the top surface of the liquid in the treatment tank 14.

[0030] Further, an electric heater 31 is provided at the bottom of the treatment tank 14. The electric heater 31 is connected to a temperature control system. The electric heater 31 can heat the inside of the treatment tank 14, enabling the packaging box fragments in the treatment tank 14 to be steamed, which is more conducive to the softening and separation of the fragments.

[0031] Furthermore, a second waste liquid pipe 34 is passed through the bottom of one side wall of the treatment tank 14, and a solenoid valve 8 is also installed at the junction of the second waste liquid pipe 34 and the treatment tank 14. A drainage pipe 33 is passed through the bottom end of the drain bucket 32, and the bottom end of the drainage pipe 33 is connected to the second waste liquid pipe 34. The drain bucket 32 ​​can quickly drain the water from the raw pulp pushed onto the screen 21, so as to facilitate the subsequent reproduction steps of the raw pulp.

[0032] Furthermore, a circulating water pump 37 is provided on one side of the grinder 11, and the first water pipe 6 and the second water pipe 12 are connected to the output end of the circulating water pump 37 through a fixed connecting pipe. The function of the circulating water pump 37 is to enable the circulating water to flow in the system in an orderly manner, so that the system can use the circulating water to save the circulating water consumed during the operation of the system.

[0033] The method of using this embodiment is as follows: when using the packaging box environmentally friendly recycling and processing system, the system can be connected to an external power supply first, and then the packaging box that has been initially split is put into the feed hopper 2. At this time, the packaging box will pass between the two squeezing rollers 3 rotating in opposite directions, so that the packaging box is squeezed into a flat shape. At this time, the residue in the packaging box will be squeezed out, and the residue will pass through the conveyor mesh belt 22 and fall into the purification pool 25 at the bottom of the bottom box 1 for treatment. Then, the packaging box that has completed squeezing will be transported by the conveyor mesh belt 22 and move to one end of the connecting bucket 10. When the box moves with the conveyor mesh belt 22, the first water pipe 6 will pump circulating water into the mesh pipe under the action of the circulating water pump 37, and then the circulating water will pass through the first nozzle 24 at the bottom of the mesh pipe 23 and spray to the surface of the packaging box, so that the residues and stains on the surface of the packaging box are washed away, and the waste water generated by the washing will pass through the conveyor mesh belt 22 and flow into the purification tank 25 for subsequent treatment. When the water level in the purification tank 25 is high, the solenoid valve 8 of the first waste liquid pipe 7 will be opened to discharge the treated water in the purification tank 25 for subsequent harmless treatment to form circulating water; After the package box is transferred to the connecting bucket 10, it will slide into the inside of the blender 11 along the connecting bucket 10 and be blended under the rotation of the rotating blade 28 inside the blender 11. When the package box is blended into pieces by the fixed blade 27 and the rotating blade 28, the second water pipe 12 will spray circulating water from the second nozzle 26 under the action of the circulating water pump 37, so that the water flow rushes to the space between the rotating blade 28 and the fixed blade 27, so that the pieces remaining in the gap between the blades flow to the bottom of the blender 11 with the water, and then the flowing solid-liquid mixture flows to the discharge hopper 30, and then falls into the processing tank 14 for the cooking step; During the cooking process of the packaging box fragments in the treatment tank 14, the packaging box fragments will separate and fibrate to form waste and virgin pulp fibers. Since the virgin pulp fibers are lighter in weight, they will float to the top of the liquid level in the treatment tank 14. When there is a large accumulation of recycled virgin pulp at the top of the liquid level in the treatment tank 14, the linear guide rail 15 will drive the slide plate 16 to move towards the draining hopper 32, driving the screening net 20 on the rotating rod 18 to move along the top of the liquid level in the treatment tank 14, so that the screening net 20 will push the virgin pulp accumulated at the top of the liquid level onto the screen 21 at the top of the draining hopper 32. When the virgin pulp is pushed onto the screen 21, the water in the virgin pulp will pass through the screen 21 and enter the draining hopper 32, and then drain away along the drainage pipe 33 at the bottom of the draining hopper 32. At this time, the collected virgin pulp can be subjected to subsequent reproduction processing. At the same time, before the slide plate 16 resets and slides back, the third motor 17 will drive the rotating rod 18 to rotate, so that the screening net 20 rotates from the vertically downward state to the vertically upward state, separating the screening net 20 from the liquid level at the top of the treatment tank 14, so that the screening net 20 will not interfere with the floating of the virgin pulp during the sliding back process.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
