Description

Technical Field

[0001] This invention relates to the field of plastic pellet waste recycling technology, and in particular to a modified recycled plastic pellet waste recycling and reuse device. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to the recycling of plastic granules is also constantly improving. Modified recycled plastic granules are plastic granules with specific properties that are made by recycling, cleaning, crushing, melting and modifying waste plastics.

[0003] Currently, plastic waste is generated during the processing of plastic parts for doors and windows. Most of this plastic waste is mixed with other plastic waste and piled up as garbage before being disposed of in a unified manner. Traditional disposal methods are mostly landfill or incineration, which not only wastes valuable resources but also easily causes serious environmental pollution. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: Currently, plastic waste is generated during the processing of plastic parts for doors and windows. This plastic waste is mostly mixed with other plastic waste and piled up as garbage before being processed in a unified manner. Traditional processing methods are mostly landfill or incineration, which not only wastes valuable resources but also easily causes serious environmental pollution. Therefore, a modified recycled plastic granule waste recycling and reuse device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for recycling and reusing modified recycled plastic granules includes a housing, on which two supports are fixedly connected. The two supports are connected through a crushing box, on which a crushing component is provided. A feed pipe is fixedly connected to the top of the crushing box.

[0007] One of the brackets is equipped with a water inlet assembly, and the other bracket is fixedly connected with two L-shaped plates. The two L-shaped plates are connected by a rectangular rod. A bidirectional screw is rotatably mounted on the two L-shaped plates. Two moving blocks are threadedly connected to the bidirectional screw, and each moving block is slidably connected to the rectangular rod.

[0008] Each of the moving blocks has a sealing block on one side, and a servo motor is installed inside the sealing block. The drive end of the servo motor is fixedly connected to a rotating cylinder, and a cleaning brush is bolted to the rotating cylinder. An ultrasonic transducer and an ultrasonic generator are installed on the housing, and a cleaning tank is opened inside the housing.

[0009] Preferably, the crushing assembly includes two crushing rollers rotatably mounted inside the crushing chamber. Multiple drive motors are fixedly connected to the crushing chamber. Each crushing roller is fixedly connected to the drive end of the corresponding drive motor. Each drive end of the drive motor is equipped with an electromagnetic brake.

[0010] Preferably, the drive ends of both drive motors are fixedly connected to sealing plates, and one side surface of each sealing plate is set as an arc surface.

[0011] Preferably, the water inlet assembly includes a water inlet pipe fixedly installed on the bracket, one end of the water inlet pipe is fixedly connected to a threaded pipe, and a sealing ring is fixedly provided on the threaded pipe.

[0012] Preferably, a perforated plate is fixedly installed inside the cleaning tank, and a guide block with a right-angled triangular cross-section is fixedly connected to the lower inner wall of the cleaning tank.

[0013] Preferably, the housing has an opening, and both sides of the opening have a discharge port and a drain port. A sealing baffle is inserted into the opening. A first electric push rod is fixedly mounted on the bracket. The drive end of the first electric push rod is fixedly connected to the sealing baffle. A guide plate with a concave cross-section is fixedly connected to the lower surface of the housing.

[0014] Preferably, each of the movable blocks has a sliding opening, and a concave block is slidably connected in the sliding opening. Each of the sealing blocks is fixedly connected to the corresponding concave block, and a vertical rod is fixedly connected to each of the concave blocks.

[0015] Preferably, a second electric push rod is fixedly connected to one of the brackets, and a U-shaped frame is fixedly connected to the drive end of the second electric push rod. Two I-shaped blocks are slidably connected inside the U-shaped frame, and the upper ends of the two vertical rods are fixedly connected to the two I-shaped blocks respectively.

[0016] Preferably, a plurality of support legs are fixedly connected to the lower surface of the housing, and each support leg is rotatably connected to a pulley.

[0017] Preferably, two hydraulic cylinders are fixedly connected to the lower surface of the housing, and a support plate is fixedly connected to the drive end of each hydraulic cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. During the rotation of the two crushing rollers, the plastic waste is crushed. After the two sealing plates are set in an inverted V-shape, the crushed plastic waste will fall into the cleaning tank under the action of gravity. The two cleaning brushes rotate to wash the plastic waste fragments in the cleaning tank. The ultrasonic transducer and ultrasonic generator work to perform ultrasonic cleaning on the plastic waste fragments. After the plastic waste fragments are cleaned, they can be discharged through the discharge port and slide down the guide plate into the collection frame for collection, so as to facilitate the recycling of waste plastics. The cleaned plastic waste fragments can be reused to manufacture modified recycled plastic granules, realizing the recycling of resources, effectively avoiding the waste of resources, and will not cause serious pollution to the environment.

[0020] 2. The second electric push rod drives the U-shaped frame to move vertically upward. Under the combined transmission action of the two I-shaped blocks and the vertical rod, the two sealing blocks and the cleaning brush move upward synchronously. Then, the motor drives the bidirectional lead screw to rotate, and the two moving blocks move along the bidirectional lead screw. The distance between the two cleaning brushes increases. When the two sealing plates rotate downward, the two cleaning brushes are located on both sides of the two sealing plates. When plastic waste fragments fall between the two inverted V-shaped sealing plates, it can effectively prevent plastic waste fragments from falling onto the two cleaning brushes, thereby preventing plastic waste fragments from hitting the cleaning brushes and splashing onto the outside of the housing, so as to facilitate the subsequent cleaning treatment of plastic waste fragments.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1-7 A modified recycled plastic granule waste recycling device includes a housing 1, on which two supports 10 are fixedly connected. The two supports 10 are connected by a crushing box 7, on which a crushing component is provided. A feed pipe 8 is fixedly connected above the crushing box 7. A water inlet component is provided on one of the supports 10, and two L-shaped plates 4 are fixedly connected to the other support 10. The two L-shaped plates 4 are connected by a rectangular rod 19. A bidirectional lead screw 20 is rotatably provided on the two L-shaped plates 4. Two moving blocks 21 are threadedly connected to the bidirectional lead screw 20, and each moving block 21 is slidably connected to the rectangular rod 19.

[0031] Each movable block 21 has a sealing block 27 on one side, and a servo motor (not shown) is installed inside the sealing block 27. The servo motor has good sealing performance when connected to the sealing block 27, which can effectively prevent the cleaning fluid or water from contacting the servo motor. The drive end of the servo motor is fixedly connected to a rotating cylinder 29. The rotating cylinder 29 is connected to a cleaning brush 12 by bolts 28. An ultrasonic transducer and an ultrasonic generator are installed on the housing 1 (the ultrasonic transducer and ultrasonic generator are existing technologies, and their working principle is not described in detail). A cleaning tank 25 is opened inside the housing 1.

[0032] The crushing assembly includes two crushing rollers 22 rotatably mounted inside the crushing chamber 7. Multiple drive motors are fixedly connected to the crushing chamber 7. Each crushing roller 22 is fixedly connected to the drive end of the corresponding drive motor. Each drive motor is equipped with an electromagnetic brake. Sealing plates 9 are fixedly connected to the drive ends of the two drive motors. One side surface of each sealing plate 9 is set as an arc surface. The two drive motors drive the two crushing rollers 22 to rotate. During the rotation of the two crushing rollers 22 inside the crushing chamber 7, the plastic waste can be crushed. The other two drive motors simultaneously drive the two sealing plates 9 to rotate. After the two sealing plates 9 rotate, they will be arranged in an inverted V-shape. Under the action of gravity, the crushed plastic waste inside the crushing chamber 7 will fall from between the two sealing plates 9 into the washing tank 25. The electromagnetic brakes can effectively prevent the drive ends of the drive motors from rotating arbitrarily.

[0033] The water inlet assembly includes a water inlet pipe 13 fixedly installed on the bracket 10. One end of the water inlet pipe 13 is fixedly connected to a threaded pipe 11. A sealing ring is fixedly installed on the threaded pipe 11. An external water pipe (not shown) is threadedly connected to the threaded pipe 11. The sealing ring is located between the threaded pipe 11 and the external water pipe, which can effectively improve the sealing performance when the threaded pipe 11 is connected to the external water pipe. The cleaning liquid or clean water can be transported to the inside of the cleaning tank 25 through the external water pipe, the threaded pipe 11 and the water inlet pipe 13 using a water pump.

[0034] A perforated plate 26 is fixedly installed inside the cleaning tank 25. A guide block 23 with a right-angled triangular cross-section is fixedly connected to the lower inner wall of the cleaning tank 25. An opening is provided on the housing 1. A discharge port 18 and a drain port are provided on both sides of the opening. A sealing baffle 17 is inserted into the opening. A first electric push rod 5 is fixedly installed on the bracket 10. The drive end of the first electric push rod 5 is fixedly connected to the sealing baffle 17. A guide plate 2 with a concave cross-section is fixedly connected to the lower surface of the housing 1. Under the filtering effect of the perforated plate 26, the cleaning liquid and clean water in the plastic waste fragments are easily drained. The cleaning liquid and clean water passing through the perforated plate 26 can be discharged from the drain port along the inclined surface of the guide block 23.

[0035] Each movable block 21 has a sliding opening 30, and a concave block 24 is slidably connected within the sliding opening 30. Each sealing block 27 is fixedly connected to the corresponding concave block 24. A vertical rod 32 is fixedly connected to each concave block 24. A second electric push rod 6 is fixedly connected to one of the brackets 10. A loop frame 3 is fixedly connected to the driving end of the second electric push rod 6. Two I-shaped blocks 31 are slidably connected within the loop frame 3. The upper ends of the two vertical rods 32 are fixedly connected to the two I-shaped blocks 31 respectively. The second electric push rod 6 drives... The loop frame 3 moves vertically upward. Under the combined transmission action of the two I-shaped blocks 31 and the vertical rod 32, the two concave blocks 24 will move vertically upward along the sliding opening 30, thereby causing the two sealing blocks 27 and the cleaning brush 12 to move upward synchronously. Then, the motor drives the bidirectional lead screw 20 to rotate, and the two moving blocks 21 will move along the bidirectional lead screw 20 and slide relative to the rectangular rod 19. The two I-shaped blocks 31 will slide along the loop frame 3 at the same time, and the distance between the two cleaning brushes 12 will increase.

[0036] Multiple support legs are fixedly connected to the lower surface of the housing 1. Each support leg is rotatably connected to a pulley 14. Two hydraulic cylinders 16 are fixedly connected to the lower surface of the housing 1. Each hydraulic cylinder 16 has a support plate 15 fixedly connected to its drive end. The pulleys 14 are used to facilitate the rapid movement of the housing 1. The two hydraulic cylinders 16 work to lift the housing 1 until the two support plates 15 contact the ground and each pulley 14 is disengaged from the ground. This effectively prevents the pulleys 14 from rolling and causing the housing 1 to move, thus preventing the housing 1 from moving arbitrarily.

[0037] In this invention, during use, plastic waste can be fed into the crushing box 7 through the feed pipe 8. Then, two drive motors drive two crushing rollers 22 to rotate. During the rotation of the two crushing rollers 22 inside the crushing box 7, the plastic waste can be crushed. After the plastic waste is crushed, the other two drive motors simultaneously drive two sealing plates 9 to rotate. In the initial state, the arc surfaces of the two sealing plates 9 are in contact, and both sealing plates 9 are in a horizontal state. At this time, the two sealing plates 9 can seal and block the bottom of the crushing box 7. After the two sealing plates 9 rotate, they will be arranged in an inverted V-shape. Under the action of gravity, the crushed plastic waste inside the crushing box 7 will fall from between the two sealing plates 9 into the washing tank 25.

[0038] Sufficient cleaning fluid is injected into the cleaning tank 25 through the water inlet pipe 13. Two servo motors drive two cleaning brushes 12 to rotate, thus cleaning the plastic waste fragments inside the cleaning tank 25. The ultrasonic transducer (not shown) and ultrasonic generator (not shown) also work to perform ultrasonic cleaning on the plastic waste fragments. The first electric push rod 5 drives the sealing baffle 17 to move vertically upward. As the sealing baffle 17 moves upward inside the opening, it gradually shifts away from the drain outlet while still sealing and blocking the discharge outlet 18. The cleaning fluid then passes through the perforated plate 26 and is discharged through the drain outlet. The discharged cleaning fluid slides down the guide plate 2. Afterward, the sealing baffle 17 is moved back to its initial position. The plastic waste fragments are repeatedly cleaned and rinsed by adding cleaning fluid or clean water into the cleaning tank 25 through the water inlet pipe 13. After the plastic waste fragments are cleaned, the first electric push rod 5 drives the sealing baffle 17 to move upward, and the sealing baffle 17 is offset from the discharge port 18. The cleaned plastic waste fragments can then be discharged through the discharge port 18 and slide down along the guide plate 2 into the collection frame (not shown) for collection, so as to facilitate the recycling of waste plastics. The cleaned plastic waste fragments can be reused to manufacture modified recycled plastic pellets, realizing the recycling of resources, effectively avoiding the waste of resources, and will not cause serious pollution to the environment.

[0039] First, the second electric push rod 6 drives the loop frame 3 to move vertically upward. Under the combined transmission action of the two I-shaped blocks 31 and the vertical rod 32, the two concave blocks 24 will move vertically upward along the sliding opening 30, thereby causing the two sealing blocks 27 and the cleaning brush 12 to move upward synchronously. Then, the motor drives the bidirectional lead screw 20 to rotate, and the two moving blocks 21 will move along the bidirectional lead screw 20 and slide relative to the rectangular rod 19. The two I-shaped blocks 31 will slide along the loop frame 3 at the same time, and the distance between the two cleaning brushes 12 will increase. When the two sealing plates 9 rotate downward, the two cleaning brushes 12 are located on both sides of the two sealing plates 9. When plastic waste fragments fall between the two inverted V-shaped sealing plates 9, it can effectively prevent plastic waste fragments from falling onto the two cleaning brushes 12, thereby preventing the phenomenon of plastic waste fragments hitting the cleaning brushes 12 and splashing onto the outside of the housing 1, so as to facilitate the subsequent cleaning treatment of plastic waste fragments.
