[0002] PET plastic is a milky white or light yellow highly crystalline polymer. PET plastic can be made into various products, but plastic products may wear out during use, which may render them unusable. In order to improve resource utilization, PET plastic fragment purification equipment is needed to clean and purify the shredded waste PET plastic.

[0003] PET plastic fragment purification equipment generally uses a friction machine to rub PET plastic fragments to remove stains from the surface of the PET plastic fragments. However, some existing PET plastic fragment purification equipment has low friction efficiency and cannot effectively remove stains from the surface of PET plastic fragments. A large proportion of PET plastic fragments need to be reworked in the purification process, which increases the cost of recycling. Therefore, a PET plastic fragment purification equipment is proposed to address the above problems. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A PET plastic fragment purification device includes a base 1, a housing assembly 2, a friction assembly 3, a cleaning assembly 4, and a collecting assembly 5. The housing assembly 2 includes multiple support legs 21 fixedly connected to the upper side of the base 1. A housing body 22 is fixedly connected to the upper side of the support legs 21. A first mounting plate 23 is fixedly connected to the uppermost inner side of the housing body 22. A second mounting plate 24 is fixedly connected to the upper side of the first mounting plate 23. The friction assembly 3 includes a fixing plate 31 fixedly connected to the inner side of the housing body 22. An outer friction shell 32 is fixedly connected to the inner side of the fixing plate 31. A position... The drive motor 35 is located on the lower side of the second mounting plate 24. The main shaft of the drive motor 35 is fixedly connected to a rotating disk 36 that is rotatably connected to the outer casing 22. The lower side of the rotating disk 36 is fixedly connected to an inner friction shell 37 located inside the outer friction shell 32. The cleaning assembly 4 includes a liquid pump 41 fixedly connected to the upper side of the second mounting plate 24. A water supply pipe 42 is fixedly connected to the left drain port of the liquid pump 41. A diversion box 43 fixedly connected to the outer friction shell 32 is fixedly connected to the end of the water supply pipe 42 away from the liquid pump 41. A filter screen 44 that passes through the outer friction shell 32 is fixedly connected to the outlet of the diversion box 43.

[0025] A drain valve 25 is fixedly connected to the lower middle position of the outer casing 22. A drain pipe 26 with a certain distance from the base 1 is fixedly connected to the lower side of the drain valve 25. A discharge valve 33 is fixedly connected to the lower front position of the outer friction shell 32. A discharge pipe 34 passing through the outer casing 22 is fixedly connected to the front side of the discharge valve 33. A feed valve 38 is fixedly connected to the front half of the rotating disk 36. The PET plastic fragments to be purified can be poured into the gap between the outer friction shell 32 and the inner friction shell 37 through the feed valve 38. The wastewater from rinsing the PET plastic fragments can flow to the drain pipe 26 through the drain valve 25. The wastewater eventually enters the wastewater tank. The discharge valve 33 allows the clean water carrying PET plastic fragments to fall from the discharge pipe 34 into the filter box 52. The receiving assembly 5 includes a drain box 51 located on the upper side of the base 1. Inside the drain box 51 is a filter box 52 with a depth less than the drain box 51. The filter box 52 and the drain box 51 are located directly below the bottom opening of the discharge pipe 34. The filter box 52 collects the PET plastic fragments and allows the clean water to flow out. The fixed plate 31 is located at a height lower than the discharge valve 33. The fixed plate 31 is an annular plate with external friction. There is a certain gap between the lower side of the shell 32 and the outer shell 22. The bottom of the outer friction shell 32 is provided with evenly distributed water filter holes. Clean water can rinse the PET plastic fragments and carry the dirt through the inner friction shell 37, the outer friction shell 32 or the fixing plate 31, and collect at the bottom of the outer shell 22 which is fixed by the support leg 21. The outer friction shell 32 is a cylindrical shell with an opening at the bottom. The inner friction shell 37 is a cylindrical shell with its bottom attached to the outer friction shell 32. The lower side of the rotating disk 36 is attached to the upper side of the outer friction shell 32. The center of the inner friction shell 37 is located behind the center of the outer friction shell 32. Due to the inner friction... The inner friction shell 37 is eccentrically positioned relative to the rotating disk 36. As the inner friction shell 37 rotates, it shifts relative to the outer friction shell 32, which is fixed by the fixing plate 31, thereby agitating the PET plastic fragments and allowing them to rub against the outer friction shell 32 and the inner friction shell 37. The diversion box 43 is an annular shell. On the side of the diversion box 43 near the outer friction shell 32, there are multiple circumferentially evenly distributed liquid outlets. The upper side of the diversion box 43 is aligned with the upper side of the outer friction shell 32. The diversion box 43 can be used for diversion, and the filter screen 44 can evenly spray clean water onto the PET plastic fragments.

[0026] Workflow: Before use, fix the base 1 in a suitable position. Connect the drain pipe 26 to the wastewater tank through the first pipe. Connect the right suction port of the liquid pump 41 to the clean water source through the second pipe. Connect the outlet on the front of the drain box 51 to the clean water recovery tank through the third pipe. Then connect the power supply. This device is equipped with an external controller, which is electrically connected to the drain valve 25, discharge valve 33, drive motor 35, feed valve 38, and liquid pump 41. Manually operating the external controller can adjust the operating status of the drain valve 25, discharge valve 33, drive motor 35, feed valve 38, and liquid pump 41 respectively. The drive motor 35 is equipped with a rotary encoder, which can accurately control the rotation angle of the inner friction shell 37, ensuring that the feed valve 38 is located above the gap between the outer friction shell 32 and the inner friction shell 37 when the inner friction shell 37 is in operation. All of the above are existing technologies. When using this device, the operator first opens the feed valve 38 via an external controller, pours the PET plastic fragments to be purified into the gap between the outer friction shell 32 and the inner friction shell 37, and then closes the feed valve 38. Then, the operator opens the drain valve 25 via the external controller and simultaneously starts the drive motor 35 and the liquid pump 41. The drive motor 35, fixed by the first mounting plate 23, can... The rotating disk 36 rotates, which in turn drives the inner friction shell 37 to rotate. Because the inner friction shell 37 is eccentrically positioned relative to the rotating disk 36, it shifts relative to the outer friction shell 32, which is fixed by the fixing plate 31, as it rotates. This agitates the PET plastic fragments, allowing them to rub against both the outer and inner friction shells, thus removing dirt from their surface. Simultaneously, a liquid pump 41, fixed by the second mounting plate 24, delivers clean water into the water pipe 42, which is then distributed through the diversion box 43 and sprayed evenly onto the PET plastic fragments through the filter screen 44. PET plastic fragments can be rinsed and carry dirt through the inner friction shell 37, outer friction shell 32 or fixed plate 31, and collect at the bottom of the outer shell 22 fixed by the support leg 21. They flow through the drain valve 25 into the drain pipe 26 and finally enter the wastewater pool. After a period of time, the PET plastic fragments are purified. The staff closes the drain valve 25 and opens the discharge valve 33 through the external controller. The clean water can carry the PET plastic fragments from the discharge pipe 34 into the filter box 52. The PET plastic fragments can be collected through the filter box 52. The clean water flows out from the outlet on the front side of the drain box 51 through the filter box 52 and finally enters the clean water recycling tank.This device uses a rotatable rotating disk 36 to drive an eccentrically positioned inner friction shell 37 to rotate, rubbing the PET plastic fragments located in the gap between the outer friction shell 32 and the inner friction shell 37. This effectively removes stains from the surface of the PET plastic fragments. Simultaneously, clean water is diverted through a diversion box 43 and sprayed through a filter screen 44 to rinse the PET plastic fragments, quickly removing stains from their surface. This device has high friction efficiency, effectively removing stains from the surface of PET plastic fragments. The proportion of PET plastic fragments requiring rework during the purification process is low, resulting in low recycling costs.
