DETAILED DESCRIPTION

[0035] The two embodiments of the present application will be described in detail below with reference to the drawings.

[0036] First embodiment:

[0037] Figures 1-5A waste plastic recycling device is shown, including a washing tank 1. A motor 2 is fixedly connected to the side of the washing tank 1. A connecting rod 3 is fixedly connected to the output end of the motor 2. Multiple flip plates 4 and a cutting blade 5 are fixedly connected to the outer end of the connecting rod 3. One end of the connecting rod 3 rotates through the washing tank 1, and the end away from the motor 2 rotates and is inserted into the inner wall of the washing tank 1. A pair of air pumps 6 are fixedly connected to the side of the washing tank 1. A hot air blower 7 is fixedly connected to the air inlet end of the air pump 6. An air inlet pipe 8 is fixedly connected to the air outlet end of the air pump 6. The end of the air inlet pipe 8 away from the air pump 6 is fixedly inserted into the interior of the washing tank 1, and its air outlet end is flush with the inner wall of the washing tank 1 and opposite to the flip plate 4 near the inner wall of the washing tank 1. A pair of water outlet pipes 17 are fixedly connected to the lower end of the washing tank 1. A valve 23 is fixedly connected to the outside of the water outlet pipes 17. A transparent plate is fixedly connected to the side of the washing tank 1 so that personnel can observe the waste plastic inside the washing tank 1.

[0038] A pair of electric push rods 9 are fixedly connected to the upper side of the cleaning tank 1. The same sealing cover 10 is fixedly connected to the telescopic end of the pair of electric push rods 9. The interior of the sealing cover 10 is a sloping structure with the sloping direction from top to bottom. During the cleaning of waste plastic, water splashes onto the inner wall of the sealing cover 10 and then slides down the sloping direction of the inner wall of the sealing cover 10 into the cleaning tank 1.

[0039] An exhaust pipe 11 is fixedly connected to the upper end of the sealing cover 10. A connecting plate 12 is fixedly connected to the inner wall of the exhaust pipe 11. An electric push rod 13 is fixedly connected to the upper side of the connecting plate 12. A sealing plate 14 is fixedly connected to the telescopic end of the electric push rod 13.

[0040] A pressure sensor 15 is fixedly connected to the lower side of the connecting plate 12, and a controller 16 is fixedly connected to the upper side of the connecting plate 12. The pressure sensor 15 and the electric push rod 13 are both electrically connected to the controller 16 through wires. The bottom of the flip plate 4 and the cutting blade 5 located on the lower side of the connecting rod 3 are in contact with the inner bottom wall of the cleaning tank 1. The side of the flip plate 4 away from the connecting rod 3 is a sloping structure.

[0041] The present invention is used in the following steps:

[0042] Step 1: When using, start the electric push rod 9 and push the sealing cover 10 upward with its telescopic end to adjust the distance between the sealing cover 10 and the cleaning tank 1. After adjusting the distance between the two, put water and waste plastic into the cleaning tank 1. Then start the electric push rod 9 again to move the sealing cover 10 downward until the lower side of the sealing cover 10 contacts the upper side of the cleaning tank 1, and use the sealing cover 10 to seal the feed port of the cleaning tank 1.

[0043] Step 2: Start motor 2, so that its output end drives the connecting rod 3 to rotate, which in turn causes multiple cutting blades 5 and the flipping plate 4 to rotate together. The flipping plate 4 is used to turn the waste plastic over in the water. At the same time, the cutting blades 5 are used to cut the waste plastic to pre-crush it, reduce the volume of the waste plastic, and facilitate subsequent processing of the waste plastic.

[0044] The cut plastic will be more easily turned over in the water under the action of the flipping plate 4 and the water flow, which can improve the cleaning effect of waste plastic. When it is turned over, the waste plastic will also rub against each other, which can further optimize the cleaning effect of waste plastic.

[0045] Step 3: After cleaning the waste plastic, place the water receiving container under the pair of water outlet pipes 17, then open the valve 23 on the water outlet pipes 17 to allow the water in the cleaning tank 1 to flow out from the water outlet pipes 17 and fall into the water receiving container below the water outlet pipes 17.

[0046] Step 4: After removing the water from the cleaning tank 1, close the valve 23 on the water outlet pipe 17 to seal the water outlet pipe 17. Then start the hot air blower 7 and the air pump 6. Use the air pump 6 to fill the cleaning tank 1 with the hot air generated by the hot air blower 7 through the air inlet pipe 8 to raise the temperature inside the cleaning tank 1 and dry the cleaned plastic.

[0047] At the same time, under the thrust of the gas, the flipping plate 4 will drive the connecting rod 3 and the cutting blade 5 to rotate together, thereby cutting the waste plastic again, increasing its crushing degree, and flipping the waste plastic so that it is heated evenly and increasing its drying speed.

[0048] During the drying process, after the pressure sensor 15 detects that the pressure inside the cleaning chamber 1 exceeds the set value, the controller 16 will start the electric push rod 13, so that its telescopic end pushes the sealing plate 14 upward until the sealing plate 14 is pushed out of the exhaust pipe 11, removing the sealing effect of the sealing plate 14 on the exhaust pipe 11. Then the exhaust pipe 11 is used to release the pressure in the cleaning chamber 1.

[0049] After drying the waste plastic, move the sealing cover 10 upward to separate the sealing cover 10 from the cleaning tank 1. Finally, take the cleaned and crushed waste plastic out of the cleaning tank 1 and process it for other processes.

[0050] In summary, when using this invention, after water and waste plastic are put into the washing tank 1, the waste plastic is stirred by the flipping plate 4 to increase the friction between the waste plastic and the water, as well as between the waste plastic and the water, thereby enhancing the cleaning effect. At the same time, the waste plastic is cut by the cutting blade 5 to increase the contact area between the waste plastic and the water, and to make it easier to rotate in the water, further improving the cleaning effect and facilitating subsequent processing of the waste plastic. When drying the waste plastic, the gas blows the flipping plate 4, which in turn drives the cutting blade 5 to rotate, so as to flip and cut the waste plastic again, thereby making the waste plastic evenly heated, increasing its drying speed, and increasing the degree of crushing of the waste plastic.

[0051] Second implementation method:

[0052] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0053] Figures 6-9 Multiple horizontal tubes 18 are movably inserted inside the water outlet pipe 17. A threaded rod 19 is threadedly connected inside the water outlet pipe 17. The threaded rod 19 is movably inserted inside the horizontal tubes 18. An electric push rod 20 is fixedly connected to the upper side of the horizontal tubes 18. A filter plate 21 is fixedly connected to the telescopic end of the electric push rod 20. The multiple filter plates 21 have the same aperture size. A pair of adjacent filter plates 21 are fixedly connected by a vertical rod 22.

[0054] A ring 24 is fixedly sleeved on the outer side of the filter plate 21. Friction texture 25 is engraved on the outer side of the ring 24. One end of the threaded rod 19 is inserted into the inner wall of the water outlet pipe 17. A pull rod 26 is fixedly connected to the lower side of the horizontal pipe 18. Anti-slip texture is engraved on the outer side of the pull rod 26. The surface of the ring 24 is slidably connected to the inner wall of the water outlet pipe 17.

[0055] A pair of guide grooves 27 are provided on the inner wall of the water outlet pipe 17. A pair of guide rods 28 are fixedly connected to the outside of the pull rod 26 and are movably inserted into the guide grooves 27. The lower side of the guide grooves 27 is connected to the water outlet end of the water outlet pipe 17. When the filter plate 21 is installed in the water outlet pipe 17, after it is inserted into the filter plate 21, the guide rods 28 enter the guide grooves 27. The guide rods 28 limit the horizontal pipe 18 to prevent it from rotating in the water outlet pipe 17 and facilitate the alignment of its installation end with the threaded rod 19, thereby facilitating the insertion of the threaded rod 19 into it.

[0056] The present invention is used in the following steps:

[0057] Step 1: When draining water using the outlet pipe 17, filter the water using the filter plate 21 to prevent plastic from entering the outlet pipe 17.

[0058] Step 2: When the flow rate and volume of water entering the outlet pipe 17 decrease due to the accumulation of plastic on the upper side, the controller 2 in the horizontal pipe 18 is used to activate the electric push rod 3 20, which pushes all the mechanisms on it to move upward together. The uppermost filter plate 21 pushes the accumulated waste plastic upward to push the waste plastic accumulated on the outlet pipe 17 away, so that water can enter the outlet pipe 17 and then the cleaning tank 1 can drain normally. After that, the other filter plates 21 can be used to filter the water.

[0059] When waste plastic accumulates again on the upper side of the water outlet pipe 17, the above steps can be repeated to push the filter plate 21 located in the middle upward and use it to push away the waste plastic accumulated on the upper side of the water outlet pipe 17.

[0060] Step 3: After drainage is complete, remove the threaded rod 19 from the outlet pipe 17, then pull the filter plate 21 to remove it from the outlet pipe 17, and use the ring 24 to scrape off the foreign matter adhering to the inner wall of the outlet pipe 17. Finally, clean the filter plate 21.

[0061] In summary, during drainage, the filter plate 21 is used to filter the plastic in the water to prevent plastic loss and waste. During the filtration process, the filter plate 21 can be pushed upward to push away the plastic accumulated at the inlet of the outlet pipe 17, so that the water in the cleaning tank 1 can smoothly enter the outlet pipe 17, thereby facilitating normal drainage of the cleaning tank 1. During the process of removing the filter plate 21 from the outlet pipe 17, the ring 24 can be used to clean the inner wall of the outlet pipe 17, improving the cleanliness of the inside of the outlet pipe 17.

[0062] like Figure 10 As shown, the present invention provides a method for recycling waste plastics, which uses the aforementioned waste plastic recycling device and includes the following steps:

[0063] S1: Put the waste plastic into the washing tank 1, use the cutting blade 5 to pre-cut the plastic, and push the plastic to move by the flip plate 4;

[0064] S2: After cleaning, the plastic is dried, and the cutting blade 5 is rotated under the push of gas to cut the plastic again;

[0065] S3: Before draining, install the filter plate 21 inside the outlet pipe 17. When draining, the filter plate 21 filters smaller plastics in the water to prevent them from moving into the outlet pipe 17. At the same time, the filter plate 21 can be moved upward to push the plastics accumulated on the bottom wall of the cleaning tank 1 upward, so that the water can smoothly enter the outlet pipe 17.
