[0002] The processing of PET bottles from bottle bodies to clean flakes is a very complicated process, which usually requires multiple processes such as sorting, crushing, and cleaning to finally obtain the finished clean flakes. Environmentally friendly recycled plastics refer to plastic raw materials obtained after processing waste plastics by physical or chemical methods such as pretreatment, melt granulation, and modification. It is the reuse of plastics. At this stage, the recycling of PET bottle flakes is widely used. The recycling work here avoids the bottle body from polluting the environment.

A transverse guide rod 112 is slidably provided in the through hole at the end of the reciprocating rack 114, and the other end of the transverse guide rod 112 is connected to the first leg frame 117. In this way, when the material ejecting rod 110 moves horizontally back and forth, the material ejecting sleeve 113 is driven to move horizontally back and forth through the lower end of the material ejecting rod 110, and the material ejecting sleeve 113 drives the reciprocating rack 114 to move horizontally back and forth, and the reciprocating rack 114 matches the reciprocating gear ring 115, so that the scraping rod 116 with it scrapes the material reciprocatingly on the inner wall of the filter cylinder 213, which helps to improve the cleaning effect of the PET sheet, and the PET sheet in the scraping state is turned over to cooperate with the spray washing operation, which helps to separate the fine sand; Working principle: In actual use, the PET flakes are first fed into the feeding hopper 100. Driven by the driving motor 106, the driving disc 103 will rotate, and the driving disc 103 will generate a driving force on the ejector rod 110 through the transmission pin 111. The ejector rod 110 will generate a thrust on the reciprocating push plate 108, so that the reciprocating push plate 108 moves back and forth up and down. When the reciprocating push plate 108 is driven to move back and forth up and down, the ejector rod 110 will move laterally along the lower end of the reciprocating push plate 108. When the reciprocating push plate 108 descends, the PET flakes inside the feeding hopper 100 will be filled to the upper end of the reciprocating push plate 108. When the reciprocating push plate 108 rises, the reciprocating push plate 108 will send away the PET flakes filled on its top, and then the PET flakes are discharged into the receiving hopper 203 along the feeding guide plate 109; The feeding motor 204 drives the transmission shaft 214 to rotate, and the transmission shaft 214 matches the transmission blade 215, thereby driving the PET flakes and the fine sand to move synchronously in the feeding cylinder 200. During the synchronous movement, the mixing rod group 216 will fully mix the PET flakes and the fine sand. During the mixing process, the surface of the PET flakes will be wiped to complete the preliminary treatment of the PET flakes. The treated PET flakes will enter the receiving guide plate 304 along the feeding pipe 217, and then smoothly enter the filter cylinder 213; The transmission unit drives the filter cylinder 213 to rotate, so that the PET sheets are constantly tumbling during the screening process to improve the screening effect. The cleaning water is sent into the horizontal pipe by the water pump, and the nozzle 300 on the lower side of the horizontal pipe sprays the cleaning water to the PET sheets, so that the fine sand in the tumbling PET sheets is separated, and the clean PET sheets enter the sheet receiving box 305, and the fine sand passes through the filter cylinder 213 and enters the rinsing recovery box group 302, and the fine sand deposited at the bottom of the rinsing recovery box group 302 is recovered.

The environmentally friendly PET bottle flakes rapid cleaning equipment according to claim 1 is characterized in that: A partition plate (107) is provided at the upper opening of the feeding hopper (100), and the partition plate (107) is arranged parallel to the reciprocating pushing plate (108).

9. The environmentally friendly PET bottle flakes rapid cleaning equipment according to claim 7, characterized in that: The screening component further comprises a turning unit for scraping and turning the PET flakes inside the filter barrel (213), thereby improving the screening effect of the PET flakes. The turning unit comprises a reciprocating gear ring (115), a bearing ring (102) is rotatably provided on the outer side of the reciprocating gear ring (115), the outer side of the bearing ring (102) is connected to the first leg frame (117) via a positioning connecting rod (101), the diameter of the reciprocating gear ring (115) corresponds to the diameter of the filter barrel (213), and a scraping rod is fixedly provided on the reciprocating gear ring (115) and is in contact with the inner wall of the filter barrel (213). (116), the cross-section of the scraper rod (116) is a fan-shaped structure, the curvature of the bottom surface of the scraper rod (116) matches the curvature of the inner wall of the filter cylinder (213), a horizontally arranged reciprocating rack (114) is meshed above the reciprocating rack (114), a material ejecting sleeve (113) is fixedly provided at the upper end of the reciprocating rack (114), the material ejecting sleeve (113) is slidably arranged with the lower end of the material ejecting rod (110), a transverse guide rod (112) is slidably provided in the through hole at the end of the reciprocating rack (114), and the other end of the transverse guide rod (112) is connected to the first leg frame (117).

10. A cleaning method for the environmentally friendly PET bottle flakes rapid cleaning equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: First, feed the PET flakes into the feeding hopper (100). Under the action of the reciprocating pusher, the reciprocating push plate (108) will reciprocate up and down along the inner wall of the feeding hopper (100). When the reciprocating push plate (108) descends, the PET flakes inside the feeding hopper (100) will be filled to the upper end of the reciprocating push plate (108). When the reciprocating push plate (108) rises, the reciprocating push plate (108) will send away the PET flakes filled on the top, and then the PET flakes will be discharged into the receiving hopper (203) along the feeding guide plate (109); Step 2: The feeding motor (204) drives the transmission shaft (214) to rotate, and the transmission shaft (214) matches the transmission blade (215), thereby driving the PET flakes and the fine sand to move synchronously in the feeding cylinder (200). During the synchronous movement, the mixing rod group (216) will fully mix the PET flakes and the fine sand. During the mixing process, the surface of the PET flakes will be wiped, thereby completing the preliminary treatment of the PET flakes. Step 3: Clean the PET sheets again through the screening component to remove the fine sand.
