Description

Technical Field

[0001] The present invention relates to the technical field of waste plastic recycling, and particularly to a waste plastic recycling device with shredding and compaction functions. Background Art

[0002] Waste plastic recycling is of great significance in environmental protection, resource conservation and economic development. Waste plastic recycling helps reduce white pollution, improve the environmental beauty of cities and villages, and by reducing the landfill of plastic waste, it reduces the occupation of land resources and the risk of groundwater pollution.

[0003] Currently, when recycling waste plastics, generally, the plastics are first cut into small pieces by a crusher, then the cut plastic materials are sorted for metals to separate the non-melting metal blocks and stones in the material pile, and then the material pile is put into a washing machine for cleaning. Finally, the plastic pile is dried and compacted into blocks for convenient transportation. However, since there are many processes in waste plastic recycling, workers need to use multiple devices simultaneously, making the process cumbersome and the operation not very convenient. Moreover, workers need to transfer the materials between different devices, resulting in the difficulty of continuous recycling of waste plastics and low recycling efficiency.

[0004] On the other hand, the waste plastic recycling device disclosed in the Chinese invention patent application publication specification CN108297308B does not require workers to transfer the materials, reducing the labor intensity of workers and improving the processing efficiency at the same time. However, it is difficult to fully clean the plastic blocks while sorting the plastic material pile. After the waste plastics are cut into small pieces of material piles, the metal blocks and stones doped in the material piles need to be separated by workers. After the sorting is completed, the material pile is put into a cleaning pool and stirred for cleaning, making it difficult to clean the plastic blocks while sorting the plastic material pile, reducing the plastic recycling efficiency. At the same time, simple stirring and cleaning are difficult to brush each plastic block, making it difficult to completely remove the stubborn mud and oil-solid caking remaining on the surface of the plastic blocks, resulting in the doping of foreign substances in the plastic material pile and affecting the subsequent plastic reshaping operation.

[0005] Therefore, we propose a waste plastic recycling device with shredding and compaction functions to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to make up for the deficiencies of the prior art and propose a waste plastic recycling device with shredding and compaction functions.

[0007] To solve the above technical problems, the present invention provides the following technical solution: A waste plastic recycling device with shredding and compaction functions, including a water collecting cylinder, a support block is fixed on the outer surface of the water collecting cylinder, a cleaning cylinder is arranged inside the water collecting cylinder, the cleaning cylinder is fixed to the support block, a feeding hopper is fixed on the outer surface of the support block, the feeding hopper is located above the cleaning cylinder, a sleeve is fixed on the inner wall of the feeding hopper, a jacking mechanism is arranged inside the sleeve, the jacking mechanism includes an outer tube fixed on the inner top wall of the sleeve, a brushing mechanism is arranged inside the cleaning cylinder, and the brushing mechanism includes an inner tube, and the inner tube is rotatably connected to the inner wall of the outer tube.

[0008] Three arc pushing plates are fixed on the outer surface of the inner tube, rotating rods are rotatably connected to the outer surfaces of the three arc pushing plates, brush rollers are slidably connected to the outer surfaces of the three rotating rods, a group of toggling forks are rotatably connected to the outer surfaces of the three brush rollers, the number of each group of toggling forks is two, limiting tubes are fixed on the outer surfaces of the three arc pushing plates, sliding rods are slidably connected to the inner walls of the three limiting tubes, the three sliding rods are respectively fixed to the three groups of toggling forks, and wedge-shaped blocks are fixed to the tops of the three sliding rods.

[0009] The jacking mechanism further includes a corrugated ring fixed on the outer surface of the outer tube, and the three wedge-shaped blocks are all adapted to the corrugated ring.

[0010] A connecting cylinder assembly and a feeding mechanism are arranged below the cleaning cylinder. The connecting cylinder assembly includes connecting cylinder one, connecting cylinder two and connecting cylinder three. Connecting cylinder one penetrates through the outer surface of the water collecting cylinder and is fixed to the water collecting cylinder. The feeding mechanism is arranged inside connecting cylinder one. The feeding mechanism includes a material transporting cylinder, and two arc-shaped filter plates are slidably connected inside the material transporting cylinder.

[0011] Further, a group of first sliding strips are fixed on the outer surfaces of the three rotating rods, the number of each group of first sliding strips is two, and the three groups of first sliding strips are respectively slidably connected to the three brush rollers. The brushing mechanism further includes a ring track, the ring track is fixed to the inner wall of the cleaning cylinder, an internal gear ring is fixed to the inner wall of the ring track, three sliding plates are slidably connected to the outer surface of the ring track, the three sliding plates are respectively rotatably connected to the three rotating rods, and three secondary gears are fixed on the outer surfaces of the three rotating rods, and the three secondary gears are all meshed with the internal gear ring.

[0012] By adopting the above technical scheme, when the inner tube rotates, the three brush rollers will be driven to rotate through the three arc push plates respectively, so that the three brush rollers will revolve in the cleaning cylinder. At the same time, since the three slave gears are meshed with the inner gear ring, the slave gears will drive the rotating rod to rotate, and the rotation of the rotating rod drives the brush rollers to rotate through the two slide bars, so that the three brush rollers rotate on themselves, and the three arc push plates rotate to move the plastic blocks on the water surface, so that the plastic blocks pass through the gap between the brush rollers and the cleaning cylinder, so that the brush rollers brush the plastic blocks.

[0013] The above-mentioned pushing mechanism also includes an annular slide rail, the three wedge blocks are all slidably connected to the annular slide rail, the annular slide rail is slidably connected to the outer surface of the outer tube, an annular baffle is fixed on the outer surface of the outer tube, and a telescopic spring is sleeved on the outer surface of the outer tube, and the two ends of the telescopic spring are respectively fixed to the annular baffle and the annular slide rail.

[0014] By adopting the above technical scheme, when the inner tube drives the arc push plate to rotate, the wedge block will rotate around the outer tube, the wedge block will be raised by the top pressure of the wave ring, and will fall and reset by the spring pressure of the telescopic spring. The wedge block will move the brush roller up and down through the toggle fork, and the plastic block will pass through the gap between the brush roller and the cleaning cylinder. The brush roller will rotate and move up and down, so that the brush roller can brush the plastic block at multiple angles, so that the stubborn mud and oil-solidified blocks on the surface can be washed off.

[0015] Furthermore, the top end of the moving rod is rotatably connected to a reciprocating threaded rod, the top end of the reciprocating threaded rod is fixed with a limit plate, the upper surface of the sleeve is fixed with a slide, the slide is slidably connected to the limit plate, the material dispensing mechanism also includes a threaded tube and a motor 1, the upper surface of the sleeve is fixed with a support plate, the support plate is rotatably connected to the threaded tube, the threaded tube is threadedly connected to the reciprocating threaded rod, the outer surface of the threaded tube is fixed with a bevel gear 2, the motor 1 is fixed to the upper surface of the sleeve, the output end of the motor 1 is fixed with a bevel gear 3, the top end of the inner tube is fixed with a bevel gear 1, and the bevel gear 2 and the bevel gear 1 are both meshed with the bevel gear 3.

[0016] By adopting the above technical solution, when the motor is started, bevel gear three drives bevel gear two to rotate, and bevel gear two drives the threaded tube to rotate. Since the reciprocating threaded rod has a reciprocating thread, the reciprocating threaded rod drives the three arc-shaped shifting racks on the moving rod to move reciprocatingly up and down, so that the upper and lower layers of the plastic material pile on the water surface in the cleaning cylinder are mixed, so that each piece of plastic can be washed by the brush roller.

[0017] The bottom end of the above-mentioned water collecting cylinder is fixedly communicated with a conical cylinder. A filter screen is fixed on the inner wall of the conical cylinder. A water storage tank is arranged below the conical cylinder. The water collecting cylinder is fixed to the water storage tank through a support frame. The bottom of the conical cylinder is fixedly communicated with the water storage tank through a hose. A water delivery pipe is fixedly communicated with the outer surface of the water storage tank. A water pump is installed on the outer surface of the water delivery pipe. One end of the water delivery pipe away from the water storage tank is located above the water collecting cylinder. A liquid level monitor is installed on the inner wall of the water collecting cylinder.

[0018] By adopting the above technical solution, start the water pump to inject the water in the water storage tank into the water collecting cylinder through the water delivery pipe, so that the water surface in the water collecting cylinder reaches the liquid level monitor. At this time, the water surface in the water collecting cylinder is at the middle surface between the top surface and the bottom surface of the arc pushing plate. The broken plastic blocks will float on the water surface, while the metal blocks and stones in the material pile will fall to the bottom due to their density being greater than that of water. A valve is arranged at the bottom of the conical cylinder. Controlling the valve of the conical cylinder can inject the water in the water collecting cylinder into the water storage tank. The metal blocks and stones in the water collecting cylinder will be filtered by the filter screen.

A spray head and a dryer are installed above the second connecting cylinder. A water collecting hopper is fixedly communicated with the lower part of the second connecting cylinder. The bottom of the water collecting hopper is fixedly communicated with the water storage tank through a hose. A channel is fixedly communicated with the lower part of the third connecting cylinder. A compactor is arranged below the connecting cylinder assembly. The compactor is installed at the bottom of the channel. The compactor is fixedly connected to the upper surface of the water storage tank. A crusher is installed on the outer surface of the water collecting cylinder. The discharge port of the crusher is located above the feeding hopper.

[0020] By adopting the above technical solution, the waste plastics will enter the cleaning cylinder after being crushed by the crusher. After the plastic blocks are sorted and cleaned, the clear water in the water collecting cylinder is emptied. The plastic blocks in the cleaning cylinder will fall into the material transporting cylinder and be supported by two arc-shaped filter plates. The material transporting cylinder moves below the spray head for secondary flushing to improve the cleanliness of the plastic blocks. Then the plastic blocks are dried by the dryer. Finally, the material transporting cylinder will move into the third connecting cylinder and open the two arc-shaped filter plates to make the plastic blocks enter the compactor for compaction.

[0021] The above-mentioned material conveying mechanism further includes a crank and a square pipe. Rotating rods are rotatably connected to the outer surfaces of the two arc-shaped filter plates. Square rods are fixed to the outer surfaces of the two rotating rods. Two limiting strips are fixed to the inner wall of the material transporting cylinder.

A straight sliding groove is formed on the outer surface of the square pipe. The straight sliding groove is slidably connected with the crank.

[0022] By adopting the above technical solution, when the crank rotates, the square tube will be moved through the straight slide groove. When the square tube moves upward, the square tube will drive the arc filter plate back to the material transport barrel through the square rod and the rotating rod, so that the two arc filter plates will open, allowing the sorted metal blocks and stones in the cleaning barrel to fall to the bottom of the water collecting barrel through the material transport barrel. When the square tube moves downward, the two arc filter plates will close. After the clean water in the water collecting barrel is drained, the plastic blocks in the cleaning barrel will fall into the material transport barrel and be supported by the two arc filter plates.

[0023] The above-mentioned feeding mechanism also includes a long rod, which is fixed on the outer surface of the crank, and a sealing cover is fixed on the outer surface of the material conveying barrel.

[0024] Furthermore, an electric telescopic rod is fixed to the outer surface of the support block, and a movable plate is fixed to the telescopic end of the electric telescopic rod, and the movable plate is rotatably connected to the long rod, and a sealing pipe cap is fixed to the end of the connecting tube three away from the connecting tube two, and the feeding mechanism also includes a rotating tube, and the rotating tube passes through the sealing pipe cap and is rotatably connected to the sealing pipe cap, and a motor 2 is fixed to the outer surface of the sealing pipe cap, and the output end of the motor 2 is transmission-connected to the rotating tube through a belt and a pulley, and two slide bars 2 are fixed to the outer surface of the long rod, and the two slide bars 2 are both slidably connected to the rotating tube.

[0025] By adopting the above technical solution, the electric telescopic rod is controlled to drive the moving plate to move, so that the moving plate drives the material transport cylinder to slide in the connecting cylinder one, the connecting cylinder two and the connecting cylinder three through the long rod, and the motor two is controlled to drive the rotating tube to rotate, so that the rotating tube drives the long rod to rotate through the two sliding bars two.

[0026] Compared with the prior art, the waste plastic recycling device with shredding and compacting function has the following beneficial effects:

[0027] 1. The present invention is provided with a pushing mechanism, a brushing mechanism and a material shifting mechanism. When the three arc push plates rotate, the plastic blocks on the water surface are shifted, so that the plastic blocks pass through the gap between the brush roller and the cleaning cylinder. The brush roller rotates and moves up and down, so that the brush roller scrubs the plastic blocks at multiple angles, so that the stubborn mud and oil-solidified blocks on the surface are washed and dropped. At the same time, the three arc-shaped shifting racks move back and forth up and down in the cleaning cylinder, so that the upper and lower layers of the plastic material pile on the water surface in the cleaning cylinder are mixed, so that each piece of plastic can be scrubbed by the brush roller, effectively avoiding the problem of stubborn mud and oil-solidified blocks on the surface of waste plastic blocks.

[0028] Second, the present invention is provided with a connecting cylinder assembly and a feeding mechanism. After the waste plastics are crushed by a crusher, they enter the cleaning cylinder. After the plastic blocks are stirred from multiple angles in the cleaning cylinder, the plastic blocks float on the water in the cleaning cylinder, while the metal blocks and stones will fall to the bottom of the water collecting cylinder. After sorting and cleaning are completed, the clear water in the water collecting cylinder is emptied, and the plastic blocks in the cleaning cylinder will fall into the material transporting cylinder and be supported by two arc-shaped filter plates. The material transporting cylinder moves under the spray head for secondary rinsing and is dried by a dryer. Finally, the material transporting cylinder will move into the connecting cylinder three and open the two arc-shaped filter plates to enable the plastic blocks to enter the compactor for compaction. This device can continuously perform cutting, sorting, cleaning, drying, and compaction operations on waste plastics, and has the advantages of simple operation, convenience, and speed.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] Please refer to Figures 1 to 12 , the present invention provides the following implementation scheme: A waste plastic recycling device with shredding and compaction functions, including a water collection cylinder 1.

[0052] Please pay special attention to Figure 1 and Figure 2 , a conical cylinder 11 is fixedly communicated with the bottom end of the water collection cylinder 1. A filter screen 18 is fixed on the inner wall of the conical cylinder 11. A water storage tank 12 is arranged below the conical cylinder 11. The water collection cylinder 1 is fixed to the water storage tank 12 through a support frame. The bottom of the conical cylinder 11 is fixedly communicated with the water storage tank 12 through a hose. A water delivery pipe 13 is fixedly communicated with the outer surface of the water storage tank 12. A water pump 14 is installed on the outer surface of the water delivery pipe 13. One end of the water delivery pipe 13 away from the water storage tank 12 is located above the water collection cylinder 1. A liquid level monitor 17 is installed on the inner wall of the water collection cylinder 1.

[0053] Start the water pump 14 to inject the water in the water storage tank 12 into the water collection cylinder 1 through the water delivery pipe 13, so that the water surface in the water collection cylinder 1 reaches the liquid level monitor 17. At this time, the water surface in the water collection cylinder 1 is at the middle surface between the top surface and the bottom surface of the arc pushing plate 603. The crushed plastic blocks will float on the water surface, while the metal blocks and stones in the material pile will fall to the bottom due to their density being greater than that of water. A valve is arranged at the bottom of the conical cylinder 11. Controlling the valve of the conical cylinder 11 can inject the water in the water collection cylinder 1 into the water storage tank 12. The metal blocks and stones in the water collection cylinder 1 will be filtered by the filter screen 18.

[0054] Please pay special attention to Figure 4 , Figure 5 and Figure 6, three arc-shaped push plates 603 are fixed to the outer surface of the inner tube 601. Rotating rods 604 are rotatably connected to the outer surfaces of the three arc-shaped push plates 603. Brush rollers 606 are slidably connected to the outer surfaces of the three rotating rods 604.

The three slide rods 610 are respectively fixed to the three sets of toggle forks 609. Wedge-shaped blocks 612 are fixed to the tops of the three slide rods 610.

[0055] Please refer specifically to Figure 4 , Figure 5 and Figure 6 , a set of first slide strips 605 are fixed to the outer surfaces of the three rotating rods 604. The number of each set of first slide strips 605 is two. The three sets of first slide strips 605 are respectively slidably connected to the three brush rollers 606. The cleaning mechanism 6 further includes an annular track 613. The annular track 613 is fixed to the inner wall of the cleaning cylinder 2. An internal gear ring 614 is fixed to the inner wall of the annular track 613. Three sliding plates 608 are slidably connected to the outer surface of the annular track 613. The three sliding plates 608 are respectively rotatably connected to the three rotating rods 604. Slave gears 607 are fixed to the outer surfaces of the three rotating rods 604. The three slave gears 607 are all meshed with the internal gear ring 614.

[0056] When the inner tube 601 rotates, it will drive the three brush rollers 606 to rotate respectively through the three arc-shaped push plates 603, so that the three brush rollers 606 revolve in the cleaning cylinder 2. At the same time, since the three slave gears 607 are meshed with the internal gear ring 614, the slave gears 607 will drive the rotating rods 604 to rotate. The rotation of the rotating rods 604 drives the brush rollers 606 to rotate through the two first slide strips 605. Thus, the three brush rollers 606 perform self-rotation. The three arc-shaped push plates 603 rotate to stir the plastic blocks on the water surface, so that the plastic blocks pass through the gap between the brush rollers 606 and the cleaning cylinder 2.

[0057] Please refer specifically to Figure 5 and Figure 7 , the jacking mechanism 5 further includes a corrugated ring 505 fixed to the outer surface of the outer tube 501. The three wedge-shaped blocks 612 are all adapted to the corrugated ring 505. A material shifting mechanism 7 is arranged inside the cleaning cylinder 2. The material shifting mechanism 7 includes a moving rod 709. The moving rod 709 is slidably connected to the inner wall of the inner tube 601. Three arc-shaped shifting frames 710 are fixed to the outer surface of the moving rod 709. One ends of the three arc-shaped shifting frames 710 are respectively slidably connected to the inner tube 601, and the ends of the three arc-shaped shifting frames 710 far from the inner tube 601 are respectively slidably connected to the three arc-shaped push plates 603.

[0058] The jacking mechanism 5 further includes an annular slide rail 503. All three wedge-shaped blocks 612 are slidably connected to the annular slide rail 503. The annular slide rail 503 is slidably connected to the outer surface of the outer tube 501. An annular baffle 502 is fixed to the outer surface of the outer tube 501. A telescopic spring 504 is sleeved on the outer surface of the outer tube 501. The two ends of the telescopic spring 504 are respectively fixed to the annular baffle 502 and the annular slide rail 503.

[0059] When the inner tube 601 drives the arc-shaped push plate 603 to rotate, the wedge-shaped block 612 will rotate around the outer tube 501. The wedge-shaped block 612 will be lifted under the top pressure of the wave ring 505 and fall back to its original position under the spring pressure of the telescopic spring 504. The wedge-shaped block 612 will drive the brush roller 606 to move up and down through the dial fork 609. The plastic block passes through the gap between the brush roller 606 and the cleaning cylinder 2. The brush roller 606 will rotate and move up and down, so that the brush roller 606 can wash the plastic block from multiple angles, and the stubborn mud and oil-solid lumps remaining on the surface will be washed off.

[0060] Please refer particularly to Figure 5 and Figure 8 As shown in FIGS. and, a reciprocating threaded rod 706 is rotatably connected to the top end of the moving rod 709. A limiting plate 707 is fixed to the top end of the reciprocating threaded rod 706. A sliding frame 708 is fixed to the upper surface of the sleeve 4. The sliding frame 708 is slidably connected to the limiting plate 707. The feeding mechanism 7 further includes a threaded tube 703 and a first motor 701. A support plate 702 is fixed to the upper surface of the sleeve 4. The support plate 702 is rotatably connected to the threaded tube 703. The threaded tube 703 is threadedly connected to the reciprocating threaded rod 706. A second bevel gear 704 is fixed to the outer surface of the threaded tube 703. The first motor 701 is fixed to the upper surface of the sleeve 4. A third bevel gear 705 is fixed to the output end of the first motor 701. A first bevel gear 602 is fixed to the top end of the inner tube 601. Both the second bevel gear 704 and the first bevel gear 602 are meshed with the third bevel gear 705.

[0061] When the first motor 701 is started, it drives the second bevel gear 704 to rotate through the third bevel gear 705. The second bevel gear 704 drives the threaded tube 703 to rotate. Since the reciprocating threaded rod 706 has a reciprocating thread, the reciprocating threaded rod 706 drives the three arc-shaped dialing frames 710 on the moving rod 709 to move up and down reciprocally, so that the upper and lower layers of the plastic material pile on the water surface in the cleaning cylinder 2 are mixed, and each piece of plastic can be washed by the brush roller 606.

[0062] Please refer particularly to Figure 9 and Figure 10, a connecting tube assembly 8 and a feeding mechanism 9 are arranged below the cleaning cylinder 2. The connecting tube assembly 8 includes a first connecting tube 801, a second connecting tube 802 and a third connecting tube 804.

[0064] The waste plastics will be crushed by the crusher 15 and then enter the cleaning cylinder 2. After the plastic blocks are sorted and cleaned, the clear water in the water collecting cylinder 1 is emptied. The plastic blocks in the cleaning cylinder 2 will fall into the material transporting cylinder 907 and be supported by the two arc-shaped filter plates 908. The material transporting cylinder 907 moves below the spray head 807 for secondary flushing to improve the cleanliness of the plastic blocks. Then the plastic blocks are dried by the dryer 808. Finally, the material transporting cylinder 907 will move into the third connecting tube 804 and open the two arc-shaped filter plates 908 to make the plastic blocks enter the compactor 16 for compaction.

[0065] Please refer specifically to Figure 9 、 Figure 10 and Figure 12 , the feeding mechanism 9 further includes a crank 913 and a square tube 911. Rotating rods 909 are rotatably connected to the outer surfaces of the two arc-shaped filter plates 908. Square rods 910 are fixed to the outer surfaces of the two rotating rods 909. Two limiting strips 917 are fixed to the inner wall of the material transporting cylinder 907. Both of the two limiting strips 917 are slidably connected to the square tube 911. Both of the two square rods 910 are slidably connected to the square tube 911. A straight sliding groove 912 is formed on the outer surface of the square tube 911. The straight sliding groove 912 is slidably connected to the crank 913.

[0066] When the crank 913 rotates, it will drive the square tube 911 to move through the straight chute 912. When the square tube 911 moves upward, the square tube 911 will drive the arc-shaped filter plate 908 to move back into the material conveying cylinder 907 through the square rod 910 and the rotating rod 909, so that the two arc-shaped filter plates 908 open, enabling the sorted metal blocks and stones in the cleaning cylinder 2 to fall to the bottom of the water collecting cylinder 1 through the material conveying cylinder 907. When the square tube 911 moves downward, the two arc-shaped filter plates 908 will close. After the clear water in the water collecting cylinder 1 is emptied, the plastic blocks in the cleaning cylinder 2 will fall into the material conveying cylinder 907 and be supported by the two arc-shaped filter plates 908.

[0067] The material conveying mechanism 9 further includes a long rod 903. The long rod 903 is fixed on the outer surface of the crank 913. A sealing cover 916 is fixed on the outer surface of the material conveying cylinder 907. The long rod 903 penetrates through the sealing cover 916 and is rotatably connected to the sealing cover 916. A limiting sleeve 915 is fixed on the outer surface of the sealing cover 916. A limiting ring 914 is fixed on the outer surface of the long rod 903. The limiting ring 914 is rotatably connected to the limiting sleeve 915. When the long rod 903 moves, the long rod 903 will drive the material conveying cylinder 907 on one side of the sealing cover 916 to move through the limiting ring 914 and the limiting sleeve 915.

[0068] Please refer specifically to Figure 9 、 Figure 10 and Figure 12 . An electric telescopic rod 901 is fixed on the outer surface of the support block 10. The telescopic end of the electric telescopic rod 901 is fixed with a moving plate 902. The moving plate 902 is rotatably connected to the long rod 903. A sealing cap 806 is fixed at the end of the connecting cylinder three 804 away from the connecting cylinder two 802. The material conveying mechanism 9 further includes a rotating tube 905. The rotating tube 905 penetrates through the sealing cap 806 and is rotatably connected to the sealing cap 806. A motor two 906 is fixed on the outer surface of the sealing cap 806. The output end of the motor two 906 is in transmission connection with the rotating tube 905 through a belt and a pulley. Two sliding strips two 904 are fixed on the outer surface of the long rod 903. Both of the two sliding strips two 904 are slidably connected to the rotating tube 905.

[0069] By controlling the electric telescopic rod 901 to drive the moving plate 902 to move, the moving plate 902 drives the material conveying cylinder 907 to slide in the connecting cylinder one 801, the connecting cylinder two 802 and the connecting cylinder three 804 through the long rod 903, and by controlling the motor two 906 to drive the rotating tube 905 to rotate, the rotating tube 905 drives the long rod 903 to rotate through the two sliding strips two 904.

[0070] Working principle: Before use, start the water pump 14 to inject the water in the water tank 12 into the water collecting cylinder 1 through the water pipe 13, so that the water level in the water collecting cylinder 1 reaches the liquid level monitor 17, and control the motor 2 906 to drive the rotating tube 905 to rotate forward, so that the rotating tube 905 drives the long rod 903 to rotate through the two slide bars 2 904, and the long rod 903 drives the crank 913 to rotate and drive the square tube 911 to move, and the square tube 911 drives the two arc filter plates 908 to slide into the material transport barrel 907 through the two square rods 910 respectively, so that the two arc filter plates 908 are opened.

[0071] When in use, waste plastics are put into the crusher 15, and the waste plastics are crushed by the crusher 15 and then enter the cleaning cylinder 2. The motor 1 701 is started to drive the bevel gear 3 705 to rotate, so that the bevel gear 1 602 rotates. The bevel gear 1 602 drives the three arc push plates 603 on the inner tube 601 to rotate, so that the three brush rollers 606 revolve in the cleaning cylinder 2. At this time, since the three slave gears 607 are meshed with the inner gear ring 614, the slave gear 607 will drive the rotating rod 6 04 rotates, the rotating rod 604 rotates through two slide bars 605 to drive the brush roller 606 to rotate, so that the three brush rollers 606 rotate on their own. At the same time, when the inner tube 601 drives the arc push plate 603 to rotate, the wedge block 612 will rotate around the outer tube 501, and the wedge block 612 will be raised by the top pressure of the wave ring 505, and fall and reset by the spring pressure of the telescopic spring 504. The wedge block 612 will move the brush roller 606 up and down through the toggle fork 609. When the plastic block passes through the gap between the brush roller 606 and the cleaning cylinder 2, the brush roller 606 will rotate and move up and down, so that the brush roller 606 can wash the plastic block at multiple angles, so that the stubborn mud and oil-solidified blocks remaining on the surface can be washed off.

[0072] When the motor 1 701 is started, it drives the bevel gear 2 704 to rotate, and the bevel gear 2 704 drives the threaded tube 703 to rotate, so that the reciprocating threaded rod 706 drives the three arc-shaped shifting frames 710 on the moving rod 709 to move back and forth up and down, so that the upper and lower layers of the plastic material pile on the water surface in the cleaning cylinder 2 are mixed, so that each piece of plastic can be washed by the brush roller 606.

[0073] After the plastic blocks are stirred at multiple angles in the cleaning cylinder 2, the plastic blocks float on the water in the cleaning cylinder 2, while the metal blocks and stone blocks will fall to the bottom of the water collecting cylinder 1. After sorting and cleaning are completed, the control motor two 906 drives the rotating pipe 905 to rotate in the reverse direction, so that the two arc-shaped filter plates 908 are closed, and the clear water in the water collecting cylinder 1 is injected into the water storage tank 12 to empty the clear water in the water collecting cylinder 1. The plastic blocks in the cleaning cylinder 2 will fall into the material transporting cylinder 907 and be supported by the two arc-shaped filter plates 908. The control electric telescopic rod 901 drives the long rod 903 to move the material transporting cylinder 907. The material transporting cylinder 907 first moves into the connecting cylinder two 802, so that the spray head 807 performs secondary flushing on the plastic blocks and dries them with the dryer 808. Then, the control material transporting cylinder 907 moves into the connecting cylinder three 804 and opens the two arc-shaped filter plates 908, so that the plastic blocks enter the compactor 16 for compaction. Thus, the device can continuously perform cutting, sorting, cleaning, drying and compaction operations on waste plastics.
