Description

Technical Field

[0001] This invention belongs to the field of plastic waste recycling technology, specifically a waste plastic recycling and granulation device. Background Technology

[0002] Waste plastics are those plastic products that we discard or use, such as plastic bags, packaging boxes, and beverage bottles. They mainly come from daily life, agricultural production, and industrial production. To reduce resource consumption, mitigate environmental pollution, save energy, and create economic value, people use waste plastic recycling and granulation equipment to recycle waste plastics.

[0003] Existing waste plastics are processed into plastic melt and then filtered using waste plastic recycling and granulation equipment to separate them from foreign matter. However, as the amount of foreign matter increases, it accumulates on the filter mechanism within the equipment. If this accumulation is not cleaned for a long time, the foreign matter will clog the filter mechanism, making it difficult to filter the plastic melt effectively. If the machine is shut down for cleaning, the limited internal space makes cleaning difficult and time-consuming, thus reducing the efficiency of filtering the plastic melt and causing significant inconvenience to personnel during waste plastic recycling. Therefore, the present invention provides a waste plastic recycling and granulation device. Summary of the Invention

[0019] 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.

[0020] Example 1: As Figures 1 to 7 and Figure 9 As shown in the figure, a waste plastic recycling and granulation device according to an embodiment of the present invention includes a recycling box 1. A filter plate 2 and a filter plate 3 are fixedly connected from top to bottom on the inner wall of the recycling box 1. The filter plate 2 has a filter hole 32 and the filter plate 3 has a filter hole 5. The diameter of the filter hole 32 is larger than the diameter of the filter hole 5. A motor 31 is fixedly connected to the bottom of the second filter plate 3. A vertical pipe 6 is fixedly connected to the output end of the motor 31. The vertical pipe 6 movably passes through the first filter plate 2 and the second filter plate 3, and extends out from the top of the recycling box 1. Several mixing rods 4 and several connecting pipes 7 are fixedly connected to the vertical pipe 6. One end of the connecting pipe 7 is connected to the vertical pipe 6. A movable rod 8 is movably inserted inside the vertical pipe 6. Several plug-in rods 9 are fixedly connected to the outside of the movable rod 8. A plug-in groove 10 is opened at the bottom of the connecting pipe 7. A lifting plate 11 is movably inserted inside the plug-in groove 10. A scraper 12 is fixedly connected to the bottom of the lifting plate 11. A magnetic coating 13 is coated on the top of the lifting plate 11. The plug-in rods 9 are movably inserted inside the plug-in groove 10. A magnetic coating 14 that is magnetically repelled by the magnetic coating 13 is coated on the plug-in rods 9. The top of the vertical pipe 6 is threaded with a threaded cap 15, and a push block 16 is fixedly connected to the inner top wall of the threaded cap 15. The top of the recycling box 1 is provided with a feeding trough 33. A vacuum cleaner 17 is fixedly connected to the vertical pipe 6. A foreign object hole 18 is provided on the scraper 12. The lifting plate 11 has a hollow internal structure. The connecting pipe 7 communicates with the vertical pipe 6. The lifting plate 11 communicates with the foreign object hole 18. A docking hole 19 is provided on the lifting plate 11. An air suction valve is provided on the scraper 12. There is a gap between the outer side of the plug rod 9 and the inner wall of the connecting pipe 7.

[0021] In the existing technology, waste plastics are processed into plastic melt and filtered using a waste plastic recycling granulation device to separate them from foreign matter. As the amount of foreign matter increases, it will accumulate on the filter mechanism in the device. If the foreign matter is not cleaned for a long time, it will clog the filter mechanism, making it difficult to filter the plastic melt normally. If the machine is stopped to clean the foreign matter, the limited internal space of the device makes cleaning difficult and takes a lot of time, which will reduce the efficiency of filtering the plastic melt and cause great inconvenience to personnel when recycling waste plastics. When using this invention, the plastic melt needs to be fed into the recycling box 1 through the feeding trough 33. Then, the motor 31 is started, and its output end drives the vertical pipe 6 to rotate together in the filter plate 1 2 and filter plate 2 3, so that the mixing rod 4 and the connecting pipe 7 rotate in the plastic melt, thereby stirring the plastic melt and improving the filtration speed. Afterwards, the plastic melt will pass through filter plate 1 2 and fall onto filter plate 2 3. At this time, some foreign objects will be filtered onto filter plate 1 2. Then, filter plate 2 3 will be used to filter the plastic melt again to improve its cleanliness. The other part of the foreign objects will be filtered onto filter plate 2 3. When the connecting pipe 7 rotates, it will drive the scraper 12, causing the scraper 12 to rotate on the filter plate 2 and the filter plate 3. The scraper 12 will scrape and push the foreign matter accumulated on the filter plate 2 and the filter plate 3, so that the filter hole 32 and the filter hole 5 are not easily blocked by foreign matter, and thus the plastic melt can be filtered smoothly. At the same time, the threaded cover 15 needs to be rotated so that it drives the push block 16 to press down the moving rod 8, thereby causing the plug rod 9 to move down. Under the magnetic repulsion between the magnetic coating 2 14 and the magnetic coating 13, the lifting plate 11 is pushed down, thereby increasing the pressure of the scraper 12 on the filter plate 1 2 and the filter plate 2 3, and optimizing the effect of scraping foreign objects. Finally, start the vacuum cleaner 17 to allow the foreign objects to enter the scraper 12, the lifting plate 11 and the vertical pipe 6 in sequence, and finally enter the vacuum cleaner 17 from the vertical pipe 6, thereby removing the foreign objects from the filter plate 2 and the filter plate 3.

[0022] In summary, when in use, this invention utilizes filter plate 2 and filter plate 3 to filter the molten plastic, separating it from foreign matter. Then, scraper 12 is used to scrape and push away the foreign matter, and the scraping intensity of scraper 12 is adjusted by lowering the moving rod 8. Finally, a vacuum cleaner 17 is activated to remove the dust from filter plate 2 and filter plate 3. Therefore, this device allows personnel to quickly remove foreign matter, and while removing foreign matter, it can continue filtering the molten plastic, thus ensuring the continuity of filtration and improving the efficiency of recycling waste plastics.

[0023] like Figure 7 As shown, in the initial state, the bottom of the push block 16 abuts against the top of the moving rod 8, and the inner wall of the vertical tube 6 abuts against the outer side of the push block 16.

[0024] like Figure 2 As shown, the side of the recycling bin 1 is provided with a pull-out groove, and a receiving box 20 is movably inserted into the pull-out groove. The plastic melt after being filtered by the filter plate 2 3 will fall into the receiving box 20. Finally, it is taken out from the pull-out groove, and then the filtered plastic melt can be processed in other processes.

[0025] like Figure 1 As shown, a pressure sensor and a controller are installed inside the receiving box 20. An indicator light 21 is fixedly connected to the side of the receiving box 20. Both the indicator light 21 and the pressure sensor are electrically connected to the controller through wires. When a certain amount of molten plastic is collected in the receiving box 20 and needs to be replaced, the indicator light 21 will light up to send a signal to remind personnel.

[0026] like Figure 1 As shown, a warning light 22 is fixedly connected to the top of the vacuum cleaner 17, and a rubber seat is fixedly connected to the bottom of the recycling bin 1. When a certain amount of foreign objects are collected in the vacuum cleaner 17 and it is necessary to remove the foreign objects, the warning light 22 will light up to issue a reminder signal.

[0027] like Figure 5 As shown, a side wall groove is provided on the inner wall of the insertion groove 10. A sealing frame 23 is fixedly connected inside the side wall groove. The inner wall of the sealing frame 23 abuts against the outer side of the lifting plate 11. The sealing frame 23 can improve the sealing between the lifting plate 11 and the insertion groove 10.

[0028] like Figure 7 As shown, a pair of symmetrically distributed disassembly rods are fixedly connected to the threaded cover 15. The outer side of the disassembly rods is engraved with anti-slip texture. The disassembly rods facilitate the application of force to the threaded cover 15 by personnel.

[0029] Example 2: Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: an installation groove is provided on the inner wall of the vertical tube 6, and a plug-in cylinder 24 is movably inserted into the installation groove. The inner wall of the plug-in cylinder 24 is coated with a magnetic coating 25 that magnetically connects with the metal material. A pair of connecting rods 26 are fixedly connected to the inner wall of the plug-in cylinder 24, and a fixed cylinder 27 is fixedly connected between the pair of connecting rods 26. The top of the fixed cylinder 27 is rotatably connected to a rotating cylinder 28 via an electric rotating shaft. Several rotating plates 29 are fixedly connected to the outer side of the rotating cylinder 28. The rotating cylinder 28 and the fixed cylinder 27 are both sleeved on the outside of the moving rod 8. A discharge hole 30 is provided on the plug-in cylinder 24.

[0030] When the present invention is in use, during the process of sucking foreign objects into the vacuum cleaner 17, when the foreign objects rise in the vertical tube 6, the electric rotating shaft can be activated, so that the rotating cylinder 28 drives the rotating plate 29 to rotate outside the fixed cylinder 27, thereby breaking up the clump of foreign objects. Then, the metallic foreign objects will be adsorbed on the magnetic coating 25, and the non-metallic foreign objects will enter the vacuum cleaner 17, thereby classifying the foreign objects. Finally, pull the connector 24 out of the vertical tube 6 and clean the metal foreign objects on the magnetic coating 25.

[0031] like Figure 8 As shown, the inner walls of both the rotating cylinder 28 and the fixed cylinder 27 have gaps with the outer side of the moving rod 8, and the side of the rotating plate 29 away from the rotating cylinder 28 has a gap with the inner wall of the insertion cylinder 24.
