Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, specifically a method and equipment for plastic recycling. Background Technology

[0002] Plastics are high-molecular polymers characterized by their lightweight, durability, and high plasticity. They come in many varieties, including polyethylene, polypropylene, and polyvinyl chloride. Due to their excellent properties such as lightness, durability, and low cost, plastics are widely used in various sectors of the national economy. However, the massive generation of waste plastics also poses a serious challenge to the global ecological environment. Traditional methods of plastic waste disposal mainly involve landfill and incineration. However, landfilling occupies land resources for a long time and poses the risk of polluting soil and groundwater; incineration may produce toxic gases such as dioxins and emit large amounts of greenhouse gases. Therefore, developing efficient and clean plastic recycling technologies is of vital strategic importance for achieving a circular economy and reducing resource consumption and environmental pollution.

[0003] The mainstream technological approaches to plastic recycling can be divided into two main categories: mechanical recycling (physical recycling) and chemical recycling. Mechanical recycling is currently the most widely used method for recycling plastics. It mainly uses physical processes such as sorting, washing, crushing, and melting granulation to reprocess waste plastics into recycled plastic pellets.

[0004] However, most existing plastic recycling and reuse equipment typically crushes waste plastics directly during use without cleaning them after crushing. This results in a high amount of impurities in the recycled crushed plastics, leading to poor quality of the recycled plastic granules produced later and affecting their reuse. Therefore, this invention provides a method and equipment for plastic recycling and reuse. Summary of the Invention

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 7 As shown in the embodiment of the present invention, a plastic recycling and reuse device includes a water storage tank 1, an inlet pipe is connected to the rear surface of the water storage tank 1, and a pipe cover is threadedly connected to the outer surface of the inlet pipe. The top of the water storage tank 1 is fixedly connected to the processing tank 2. The processing tank 2 has a processing groove 17 inside. The upper surface of the processing groove 17 extends to the outside of the processing tank 2. The water storage tank 25 has a water storage trough 25 inside. Multiple evenly distributed filter holes 30 are opened between the water storage tank 25 and the processing groove 17. Through grooves are opened at the front and rear of the left and right sides inside the processing groove 17. Rotating rods 4 27 are rotatably connected to the through grooves through bearings. Rotating rods 2 18 are fixedly connected between the two front rotating rods 4 27 and the two rear rotating rods 4 27. Multiple evenly distributed crushing wheels 3 are fixedly connected to the outer surface of the rotating rods 2 18. The multiple front crushing wheels 3 and the multiple rear crushing wheels 3 are arranged crosswise. A stirring assembly is installed at the bottom of the processing tank 17. A driving assembly is installed between the stirring assembly and the rotating rod 27. A filter assembly is installed inside the water storage tank 25. A water spraying assembly is installed between the water storage tank 1 and the processing tank 2. During operation, an appropriate amount of water is injected into the water storage tank 1 through the water inlet pipe, and the pipe cover is closed to prevent water from overflowing. The driving assembly drives the rotating rod 27 and the rotating rod 18 to rotate, and the rotation of the rotating rod 18 drives the crushing wheel 3 to rotate. The plastic to be recycled is put into the upper surface of the processing tank 17. The crushing wheel 3 crushes the plastic. At the same time, the water spraying assembly sprays water into the processing tank 17 to clean the plastic during the crushing process. The cleaned water flows into the water storage tank 25 through the filter hole 30. The filter assembly in the water storage tank 25 filters the impurities in the water. The filtered water can be extracted again by the water spraying assembly for recycling. The driving assembly can also drive the stirring assembly to rotate and stir the crushed and cleaned plastic in the processing tank 17 to make it more uniform. After processing, the processed plastic can be taken out for reuse.

[0022] In a preferred embodiment of the present invention, the water spray assembly includes a water pump 6 fixedly installed at the top rear of the water storage tank 1. A U-shaped pipe 7 is fixedly installed between the water pump 6 and the water storage tank 1. A connecting pipe 15 is fixedly installed below the rear surface of the treatment tank 2 via an L-shaped fixing plate 20. An L-shaped connecting pipe 14 is fixedly installed between the connecting pipe 15 and the water pump 6. Multiple evenly distributed nozzles 16 are fixedly installed through the lower rear surface of the interior of the treatment tank 17. The rear ends of the nozzles 16 extend to the outside of the treatment tank 2 and are fixedly installed with the connecting pipe 15. During operation, the water pump 6 is started, and the water pump 6 draws water from the water storage tank 1 through the U-shaped pipe 7. Then, the water is transported to the connecting pipe 15 through the L-shaped connecting pipe 14. The connecting pipe 15 then distributes the water to each nozzle 16. The nozzles 16 spray water evenly into the treatment tank 17 to clean the plastic being crushed by the crushing wheel 3, effectively removing dirt and impurities from the surface of the plastic and improving the purity of the recycled plastic.

[0023] In a preferred embodiment of the present invention, the filter assembly includes a slot 31 formed in the inner sidewall of the water storage tank 25. The front surface of the slot 31 has a through groove. An insert plate 24 is inserted into the slot 31. The insert plate 24 has a through slot. A filter screen 23 is fixedly connected inside the slot. During operation, the cleaned water flows into the water storage tank 25 through the filter holes 30. The water flows through the filter screen 23 on the insert plate 24. The filter screen 23 can effectively intercept impurities and particulate matter in the water, thus purifying the water. The purified water accumulates in the water storage tank 25 so that it can be extracted and reused by the water spray assembly later.

[0024] In a preferred embodiment of the present invention, a mounting plate 19 is fixedly connected to the front surface of the insert plate 24. The mounting plate 19 is inserted into the groove and fixedly installed to the water storage tank 1 by mounting bolts. A handle is fixedly connected to the front surface of the mounting plate 19. U-shaped handles are fixedly connected to the top of both the left and right sides of the water storage tank 1. During operation, when it is necessary to clean or replace the filter screen 23, the operator can unscrew the mounting bolts and pull the mounting plate 19 out of the groove by the handle, and then take the insert plate 24 out of the slot 31 to perform the corresponding operation on the filter screen 23. After cleaning or replacement, the insert plate 24 is inserted back into the slot 31, the mounting plate 19 is inserted back into the groove, and fixed by the mounting bolts. The operation is simple and convenient, and the U-shaped handle makes it easy for the operator to move the entire device.

[0025] In a preferred embodiment of the present invention, the drive assembly includes a mounting slot 26 located on the upper right side inside the processing box 2. A rotating rod 27 passes through the mounting slot 26. A spur gear 29 is fixedly connected to the outer surface of the rotating rod 27 on the front right side inside the mounting slot 26. A spur gear 28 is fixedly connected to the outer surface of the rotating rod 27 on the rear right side inside the mounting slot 26. The spur gear 28 meshes with the spur gear 29. A motor 4 is fixedly mounted on the rear right side of the processing box 2. The output end of the motor 4 is connected to the right side of the rotating rod 27 on the rear right side. The end is fixedly connected; during operation, the motor 4 is started, and the output end of the motor 4 drives the right rear rotating rod 27 to rotate. The spur gear 28 on the right rear rotating rod 27 rotates accordingly. Since the spur gear 28 meshes with the spur gear 29, the spur gear 29 will drive the right front rotating rod 27 to rotate synchronously, thereby realizing the linkage of the two rotating rods 27. The rotation of the rotating rod 27 drives the rotating rod 28 to rotate, which ultimately makes the crushing wheel 3 rotate to crush the plastic. At the same time, the rotation of the rotating rod 27 also provides power for the subsequent operation of the stirring component.

[0026] In a preferred embodiment of the present invention, the stirring assembly includes a fixed plate 20 fixedly connected to the lower part of the processing tank 17. The fixed plate 20 has an inner groove 32 inside, and the upper and lower surfaces of the inner groove 32 are provided with through mounting holes 35. A rotating rod 22 passes through the mounting holes 35. The rotating rod 22 is rotatably connected to the mounting holes 35 through a sealed bearing. A transmission assembly is provided between the rotating rod 22 and the rotating rod 27 on the right front. Multiple evenly distributed L-shaped stirring rods 21 are fixedly connected to the lower part of the outer surface of the rotating rod 22. During operation, the rotating rod 27 rotates under the drive of the drive assembly, and the power is transmitted to the rotating rod 22 through the transmission assembly. The rotating rod 22 rotates in the inner groove 32, and the multiple L-shaped stirring rods 21 fixedly connected to the lower part of its outer surface also rotate, stirring the crushed and cleaned plastic in the processing tank 17, making the plastic more evenly distributed in the processing tank 17, ensuring that each part of the plastic is fully crushed and cleaned, and improving the quality and uniformity of the recycled plastic.

[0027] In a preferred embodiment of the present invention, the transmission assembly includes a helical gear 33 fixedly connected to the outer surface of the rotating rod 22 and located inside the inner groove 32; a rotating rod 13 extends through the right side of the fixed plate 20; the right end of the rotating rod 13 extends to the outside of the processing box 2 and is fixedly connected to a pulley 11; a support plate 12 is fixedly connected to the right side of the processing box 2; the right end of the rotating rod 13 extends through the support plate 12 and is rotatably connected to the support plate 12 via a bearing; a helical gear 34 is fixedly connected to the left end of the rotating rod 13, and the helical gear 34 meshes with the helical gear 33; and a pulley 9 is fixedly connected to the right end of the front rotating rod 27 via a connecting rod 8. The pulley 9 and the belt pulley 11 are connected by a transmission belt 10. During operation, the front rotating rod 27 rotates under the drive of the drive assembly, which in turn drives the belt pulley 9, which is fixedly connected by the connecting rod 8, to rotate. The belt pulley 9 transmits power to the belt pulley 11 through the transmission belt 10. The belt pulley 11 drives the rotating rod 13 to rotate, and the helical gear 34 at the left end of the rotating rod 13 rotates accordingly. Since the helical gear 34 meshes with the helical gear 33, the helical gear 33 drives the rotating rod 22 to rotate, thereby transmitting the power of the rotating rod 27 to the rotating rod 22, so that the rotating rod 22 can drive the L-shaped stirring rod 21 to stir the plastic in the processing tank 17.

[0028] In a preferred embodiment of the present invention, a through-type discharge port is provided below the front surface of the processing tank 2. A cover plate 5 is inserted into the discharge port and is fixedly installed to the processing tank 2 by fixing bolts. During operation, after the plastic in the processing tank 17 has completed the crushing, washing, and stirring processes, the operator can unscrew the fixing bolts and remove the cover plate 5 from the discharge port. At this time, the processed plastic can be smoothly discharged from the discharge port for subsequent reuse operations. This design makes the discharge process convenient and quick, and can efficiently remove the processed plastic, improving the working efficiency of the entire recycling process. It also facilitates the cleaning and maintenance of the inside of the processing tank 2, ensuring the long-term stable operation of the equipment.

[0029] like Figure 8 As shown, the present invention discloses a method for recycling and reusing plastics, which uses the aforementioned plastic recycling and reusing equipment and includes the following steps: S1. The plastic to be recycled is put into the processing box 2 through the top of the processing tank 17. The motor 4 is started. The motor 4 drives the right rear rotating rod 27 to rotate. The right rear rotating rod 27 rotates through the meshing of the spur gear 1 28 and the spur gear 2 29, which in turn drives the right front rotating rod 27 to rotate, thereby driving the crushing wheel 3 to rotate. The crushing wheel 3 crushes the plastic that is put in. S2. The right front rotating rod 4 27 drives the rotating rod 3 22 to rotate through the transmission assembly. The rotating rod 3 22 drives the L-shaped stirring rod 21 to rotate. At the same time, the water pump 6 is started. The water pump 6 delivers the water in the water storage tank 1 to the nozzle 16 through the U-shaped pipe 7, the L-shaped connecting pipe 14 and the connecting pipe 15. The nozzle 16 sprays the water into the treatment tank 17. The L-shaped stirring rod 21 stirs the crushed plastic to make it fully mixed with the water, so as to achieve the purpose of cleaning the plastic. S3. The cleaned water flows into the water storage tank 25 through the filter hole 30, and the filter component in the water storage tank 25 filters the water. The filtered water can be pumped out again by the water pump 6 for reuse, realizing the recycling of water. S4. After cleaning, open the cover plate 5 and remove the cleaned plastic from the discharge port to complete the recycling and reuse of the plastic.
