[0022] Among them, the cleaning device includes a lower water tank 10 fixedly connected to the right side of the separation and extraction box 1, a water pump 11 fixedly installed on the upper side of the water tank 10 and a drainage pipe 12 connected to the left side of the water pump 11. A baffle 5 is fixedly connected to the middle part of the inner side of the separation and extraction box 1, and a water barrier box 6 is fixedly connected to the right side of the baffle 5. A first electric push rod 7 is fixedly installed inside the water barrier box 6, and a moving plate 8 is fixedly connected to the output end of the first electric push rod 7. The internal rotating sleeve on the left side of the separation and extraction box 1 is provided with a rotating plate 2, and the right end of the lower side of the separation and extraction box 1 is connected to a discharge pipe 9. An electromagnetic valve is installed on the front end face of the discharge pipe 9, and a slide groove matching the upper side of the threaded sleeve 16 is provided inside the upper side of the positioning frame 14.

[0023] The working principle of the above embodiment is:

[0024] The recycled PET bottle flakes are placed in the filter box 19, and the first drive motor 15 drives the threaded sleeve 16 to move to the upper right end of the separation and extraction box 1. As the second electric push rod 25 pushes the filter box 19 downward to the inside of the separation and extraction box 1, the water pump 11 absorbs the water in the water tank 10 and discharges it to the surface of the PET bottle flakes from the drain pipe 12. The second drive motor 21 starts the stirring shaft 22 to rotate and align the PET bottle flakes to stir and remove impurities such as dirt, labels, glue, etc. on the surface. After cleaning, the second electric push rod 25 drives the filter box 19 to move to a parallel position of the drying unit 13 to align the PET bottle flakes for rapid drying. During this period, the stirring shaft 22 continues to stir to remove fine impurities and powder remaining in the PET bottle flakes. The impurities that are not removed fall naturally and mix with the water mixed with oil, dirt and glue and accumulate at the bottom of the separation and extraction box 1. Then the threaded rod 17 drives the threaded sleeve 16 to move left to the upper left end of the separation and extraction box 1. The second electric push rod 25 moves to the inside of the separation and extraction box 1 again, and the filter plate 24 is rotated by the third drive motor 23 to discharge the dried PET bottle flakes without impurities into the separation and extraction box 1. After the static eliminator 3 is connected to the external power supply, the electrode 4 is started to generate an electric field and release the charge, thereby achieving the function of destaticization. Finally, the first electric push rod 7 drives the moving plate 8 to push the destaticized PET bottle flakes to move left. After the rotating plate 2 is rotated by the thrust and connected to the outside world, the PET bottle flakes are discharged.

[0025] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
