Description

Technical Field

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

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

[0003] At present, when recycling waste plastics, the plastics are generally cut into small pieces by a crusher, and then the cut plastic material pile is subjected to metal sorting to separate the non-meltable metal blocks and stones in the material pile, and then the material pile is put into a cleaning machine for cleaning, and finally the plastic pile is dried and compacted into blocks for easy transportation. However, due to the large number of processes in the recycling of waste plastics, the staff need to use multiple devices at the same time, making the process cumbersome and inconvenient to operate, and the staff need to transfer the materials between different devices, which makes the recycling of waste plastics difficult to carry out continuously and the recycling efficiency is low.

[0004] On the other hand, the waste plastic recycling device disclosed in the Chinese invention patent application disclosure CN108297308B does not require workers to transfer materials, which reduces the labor intensity of workers and improves processing efficiency. However, it is difficult for the above device to fully clean the plastic blocks while sorting the plastic material pile. After the waste plastic is cut into small piles, the metal blocks and stones mixed in the pile need to be separated by workers. The pile after sorting is put into the 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 is difficult to brush each plastic block, making it difficult to completely remove the stubborn mud and oil-solidified blocks remaining on the surface of the plastic block, resulting in foreign matter mixed in the plastic material pile, affecting the subsequent plastic reshaping operation.

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

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

The outer surfaces of the three arc push plates are fixed with limiting tubes, the inner walls of the three limiting tubes are slidably connected to sliding rods, the three sliding rods are respectively fixed to the three groups of shift forks, and the tops of the three sliding rods are fixed with wedge blocks.

[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.

[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 water collecting cylinder is fixedly connected to a conical cylinder, a filter is fixed to 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 connected to the water storage tank through a hose, the outer surface of the water storage tank is fixedly connected to a water pipe, a water pump is installed on the outer surface of the water pipe, one end of the water pipe away from the water storage tank is located above the water collecting cylinder, and a liquid level monitor is installed on the inner wall of the water collecting cylinder.

[0018] By adopting the above technical solution, the water pump is started to inject the water in the water storage tank into the water collecting cylinder through the water pipe, so that the water level in the water collecting cylinder reaches the liquid level monitor. At this time, the water level in the water collecting cylinder is at the middle surface between the top surface and the bottom surface of the arc push plate. The broken plastic blocks will float on the water surface, while the metal blocks and stones in the pile will fall to the bottom because their density is greater than that of water.

After the plastic blocks are sorted and cleaned, the clean water in the water collecting cylinder will be drained, and the plastic blocks in the cleaning cylinder will fall into the material transport cylinder and be supported by two arc-shaped filter plates. The material transport cylinder moves to the bottom of the spray head for secondary washing to improve the cleanliness of the plastic blocks. Then the plastic blocks are dried by the dryer.

When the square tube moves downward, the two arc filter plates will close.

[0049] Please refer to Fig. 9 , Fig.10 and Fig.12 An electric telescopic rod 901 is fixed to the outer surface of the support block 10, and a movable plate 902 is fixed to the telescopic end of the electric telescopic rod 901. The movable plate 902 is rotatably connected to the long rod 903. A sealing pipe cap 806 is fixed to the end of the connecting tube 3 804 away from the connecting tube 2 802. The feeding mechanism 9 also includes a rotating tube 905, which passes through the sealing pipe cap 806 and is rotatably connected to the sealing pipe cap 806.

Two slide bars 2 904 are fixed to the outer surface of the long rod 903, and the two slide bars 2 904 are both slidably connected to the rotating tube 905.

[0050] By controlling the electric telescopic rod 901 to drive the moving plate 902 to move, the moving plate 902 drives the material transport cylinder 907 to slide in the connecting cylinder 1 801, the connecting cylinder 2 802 and the connecting cylinder 3 804 through the long rod 903, and the motor 2 906 is controlled to drive the rotating tube 905 to rotate, so that the rotating tube 905 drives the long rod 903 to rotate through the two sliding bars 2 904.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] After the plastic blocks are stirred at multiple angles in the cleaning cylinder 2, they float on the water in the cleaning cylinder 2, while the metal blocks and stones will fall to the bottom of the water collection cylinder 1. After the sorting and cleaning are completed, the control motor 2 906 drives the rotating tube 905 to rotate in the opposite direction, thereby closing the two arc filter plates 908, injecting the clean water in the water collection cylinder 1 into the water storage tank 12, and draining the clean water in the water collection cylinder 1. The plastic blocks in the cleaning cylinder 2 will fall into the material transport cylinder 907 and be supported by the two arc filter plates 908. , control the electric telescopic rod 901 to drive the long rod 903 to move the material transport barrel 907, the material transport barrel 907 first moves to the connecting barrel 2 802, so that the spray head 807 performs secondary washing on the plastic blocks and the plastic blocks are dried by the dryer 808, and then the material transport barrel 907 is controlled to move to the connecting barrel 3 804 and open the two arc-shaped filter plates 908, so that the plastic blocks enter the compactor 16 for compaction, so that the device can continuously cut, sort, clean, dry and compact the waste plastics.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
