Description

Technical Field

[0001] This invention relates to the field of waste plastic recycling technology, specifically to a recycling and processing device based on waste plastic recycling. Background Technology

[0002] Waste plastics, or simply waste plastics, encompass plastic components that have lost their original function and are discarded after use in civilian, industrial, agricultural, and medical settings. It also includes scraps and waste generated during plastic processing. The recycling process for waste plastics generally involves crushing, washing, and granulation. With the continuous expansion of plastic product applications, the recycling of waste plastics is an important means of conserving resources and protecting the environment. In waste plastic processing, the waste plastics are first crushed, and then the crushed plastic fragments are washed to remove mud, oil, label residue, and various impurities adhering to the surface, ensuring the quality of raw materials for subsequent granulation. Waste plastics are widely generated in daily life, industrial production, agricultural operations, and the medical field, and are currently a renewable resource with a very large output. Recycling, crushing, washing, and granulating waste plastics can effectively reduce plastic waste accumulation, reduce environmental pollution, and achieve resource recycling, saving virgin plastic raw materials. This aligns with the current development needs of green production and resource regeneration. In industrial production processes, it is often necessary to wash batches of waste plastics of different materials and colors. Currently, most cleaning equipment on the market consists of a single cleaning tank or a continuous cleaning production line. When the same equipment processes different batches of plastic raw materials sequentially, plastic debris from the previous batch can easily accumulate in the equipment's internal cavity, conveying pipelines, and filter screens. This residual debris can be mixed into the next batch of material, causing cross-contamination due to the mixing of plastics of different materials and colors. This problem reduces the purity and quality of recycled plastics, and in severe cases, can downgrade or even render the entire batch of raw materials unusable, increasing production losses and processing costs.

[0003] Therefore, this invention proposes a recycling and processing device based on waste plastic recycling to solve the aforementioned problems. Summary of the Invention

[0036] After the plastic is crushed, the electric push rod 68 is first controlled to lower the side block 67, which in turn lowers the lifting cylinder 63 on the bearing 66. The lifting cylinder 63 then lowers the rotating roller 65, which in turn lowers the washing cylinder 611. Then, the first motor 2 drives the top rod 61 to rotate, which in turn rotates the rotating roller 65, which in turn rotates the washing cylinder 611, bringing it directly below the mounting frame 32. At this point, the new washing filter cylinder 618 rotates directly below the crushing unit 8, facilitating further crushing of the plastic. This allows for continuous crushing of the plastic and the processing of multiple batches of different plastics, preventing contamination from mixing. Then, the electric push rod 68 is controlled to drive the washing cylinder 611... As the pump rises, the cleaning cylinder 611 moves the top ring 619 on the cleaning filter cylinder 618, connecting the positioning hole 620 on the top ring 619 with the bottom rod 35. The pump body 311 is connected to an external water source. At this time, the pump body 311 and the second motor 310 are started. The pump body 311 draws external water into the rotating pipe 33 and guides the external water into the cleaning cylinder 611. At the same time, the second motor 310 drives the rotating rod 36 to rotate, which in turn drives the first gear assembly 37 to rotate. The first gear assembly 37 drives the second gear assembly 38 to rotate, which in turn drives the rotating pipe 33 to rotate. The rotating pipe 33 drives the turntable 34 to rotate, which in turn drives the cleaning filter cylinder 618 on the bottom rod 35 to rotate, facilitating the cleaning of the plastic under centrifugal force.

Two branch rods 87 are rotatably connected to the inner side of the crushing box 82. A crushing roller 88 is fixedly connected to the outer side of the branch rods 87. Gear components 89 are fixedly connected to the outer ends of the two branch rods 87. A funnel 83 is located below the top frame 81 and communicates with the crushing box 82. A discharge pipe 84 is fixedly connected to the lower side of the funnel 83. A contact ring 85 is fixedly connected to the lower side of the discharge pipe 84. The contact ring 85 contacts the top ring 619 to facilitate the plastic falling into the cleaning filter cylinder 618. When the motor 86 is started, the motor 86 drives the branch rods 87 to rotate, and the branch rods 87 drive the crushing roller 88 to rotate, so that the crushing roller 88 can crush the waste plastic. Under the action of the funnel 83 and the discharge pipe 84, the plastic can easily fall into the cleaning cylinder 611.

[0039] Drain pipes 614 are fixedly connected to the lower sides of the left and right bottom covers 612. Valves 615 are installed on the outer side of the drain pipes 614.

The baffle 651 is located outside the front block 643.

[0040] After the plastic washing is completed, valve 615 is opened to drain the water from the washing drum 611. Then, the electric push rod 649 is controlled to move the connecting plate 648. The connecting plate 648 drives the inclined plate 646 to rotate. The inclined plate 646 drives the rectangular plate 645 to move. Since the inclined plates 646 on both sides are symmetrically distributed, the rectangular plates 645 on both sides move away from each other. The rectangular plate 645 drives the front block 643 to move. The front block 643 drives the toothed plate 644 to move. When the toothed plate 644 contacts the baffle 651, as the front block 643 moves, the toothed plate 644 drives the baffle 651 to move. The baffle 651 drives the stabilizing plate 650 to move. The stabilizing plate 650 drives the control plate 625 to move. The control plate 625 drives the sealing ring 613 and the bottom cover 612 to move, so that the bottom cover 612 and the sealing ring 613 on the left and right sides move away from each other, which facilitates the rapid discharge of plastic from the washing drum 611 and the collection of materials. The plastic is then transported by the material conveyor belt 9 at the bottom.

A gear component 640 is fixedly connected to the front end of the control rod 638. The front block 6... A toothed plate 644 is fixedly connected to the outer side of 43, meshing with gear component 640.

When the two bottom covers 612 approach each other, bottom cover 612 and sealing ring 613 rise, increasing the sealing performance of the connection between bottom cover 612 and sealing ring 613.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] Working principle: Starting motor 3 (86) drives branch rod 87 to rotate, which in turn drives crushing roller 88 to rotate, facilitating the crushing of waste plastic. The plastic then falls into washing cylinder 611 via funnel 83 and discharge pipe 84. After crushing, electric push rod 1 (68) lowers side block 67, which in turn lowers lifting cylinder 63 on bearing 1 (66). Lifting cylinder 63 lowers rotating roller 65, which in turn lowers washing cylinder 611. Then, first motor 2 drives top rod 61 to rotate, which in turn rotates rotating roller 65, which in turn rotates washing cylinder 611, bringing it directly below mounting frame 32. At this point, new washing filter cylinder 618 rotates directly below crushing unit 8, facilitating further crushing of the plastic and achieving continuous crushing of multiple plastics. Different batches of plastics are processed separately to avoid mixing and causing pollution. Then, the electric push rod 68 is controlled to drive the cleaning cylinder 611 to rise. The cleaning cylinder 611 drives the top ring 619 on the cleaning filter cylinder 618 to connect the positioning hole 620 on the top ring 619 with the bottom rod 35. The pump body 311 is connected to an external water source. At this time, the pump body 311 and the second motor 310 are started. The pump body 311 draws external water into the rotating pipe 33 and introduces the external water into the cleaning cylinder 611. At the same time, the second motor 310 drives the rotating rod 36 to rotate. The rotating rod 36 drives the first gear assembly 37 to rotate. The first gear assembly 37 drives the second gear assembly 38 to rotate. The second gear assembly 38 drives the rotating pipe 33 to rotate. The rotating pipe 33 drives the turntable 34 to rotate. The turntable 34 drives the cleaning filter cylinder 618 on the bottom rod 35 to rotate, which facilitates the cleaning of the plastic under the action of centrifugal force.

[0044] After the plastic washing is completed, valve 615 is opened to drain the water from the washing drum 611. Then, the electric push rod 649 is controlled to move the connecting plate 648. The connecting plate 648 drives the inclined plate 646 to rotate. The inclined plate 646 drives the rectangular plate 645 to move. Since the inclined plates 646 on both sides are symmetrically distributed, the rectangular plates 645 on both sides move away from each other. The rectangular plate 645 drives the front block 643 to move. The front block 643 drives the toothed plate 644 to move. When the toothed plate 644 contacts the baffle 651, as the front block 643 moves, the toothed plate 644 drives the baffle 651 to move. The baffle 651 drives the stabilizing plate 650 to move. The stabilizing plate 650 drives the control plate 625 to move.
