[0030] Please refer to Figures 1-5 , the present utility model provides a technical solution: a PET bottle chip cleaning and impurity removing device, including: a mounting box 1, a cleaning box 2, a feed inlet 3, a cleaning cylinder 4, a stirring rod 5, a first gear 6, a second gear 7, a limiting disc 8, a water inlet hopper 9, a filtering box 10, a sewage box 11, a mounting cylinder 12, a screw rod 13, a centrifuge 14, a threaded rod 15, a moving plate 16, a baffle plate 17, a limiting rod 18, a fixing plate 19, a rotating plate 20 and a strong magnet 21.
[0031] When using this PET bottle chip cleaning and impurity removing device, first as Figure 1 and Figure 2 shown, the feed inlet 3 is fixedly installed at the upper end of the mounting box 1, and a cleaning cylinder 4 is arranged below the feed inlet 3. The cleaning cylinder 4 is rotatably connected to the inner side of the upper section of the mounting box 1, and an opening is arranged at the upper end of the cleaning cylinder 4. The left end of the stirring rod 5 is fixedly installed with a motor, and the stirring rod 5 is rotatably connected to the inside of the cleaning cylinder 4. The middle of the right end of the cleaning cylinder 4 is fixed with a second gear 7, and the upper side of the second gear 7 is meshed and driven with the first gear 6. And the right end of the central axis of the first gear 6 is fixedly connected with the motor. The left end of the cleaning cylinder 4 is rotatably connected to the limiting disc 8, and the limiting disc 8 is fixedly connected to the inner wall of the mounting box 1;
[0032] Put the broken PET bottle chips into the inside of the cleaning cylinder 4 from the feed inlet 3, add clear water and a cleaning agent into the cleaning cylinder 4, turn on the motor at the left end of the stirring rod 5, and the stirring rod 5 rotates inside the cleaning cylinder 4 to stir the bottle chips, so as to soften and wash away the sticky dust, residual glue and pollutants on them. After this step is completed, turn on the motor connected to the first gear 6, and the first gear 6 drives the second gear 7 and the cleaning cylinder 4 to rotate. The limiting disc 8 increases the rotation stability of the cleaning cylinder 4;
[0033] A water inlet hopper 9 is installed below the cleaning cylinder 4, and the upper section of the water inlet hopper 9 is sleeved on the outside of the cleaning cylinder 4, and the water inlet hopper 9 is fixedly connected to the inner wall of the mounting box 1. The lower end of the water inlet hopper 9 extends into the filtering box 10, and the filtering box 10 is fixed to the inner side of the lower section of the mounting box 1. A sewage box 11 is installed below the filtering box 10, and the sewage box 11 is arranged at the bottom of the mounting box 1;
[0034] When the cleaning cylinder 4 has its open end facing downwards, the mixture falls inside the drain hopper 9 and enters the interior of the filter box 10 along the inclined surface of the drain hopper 9. The sewage enters the sewage tank 11 through the through holes of the filter box 10, and the interior of the filter box 10 is inclined to facilitate the bottle flakes to fall on the right section of the filter box 10.

Therefore, the bottle flakes entering the interior of the cleaning box 2 float on the water surface, and the solid impurities with a large density settle at the bottom of the cleaning box 2, further completing the impurity removal work. Rotate the threaded rod 15 to make the moving plate 16 move left and right. The moving plate 16 is kept stable through the limiting rod 18, and the dial 17 is driven to continuously stir the bottle flakes, facilitating the quick removal of the impurities on them and saving time;
