Technical Field

[0001] The utility model relates to the technical field of waste plastic treatment, in particular to a waste plastic cleaning device. Background Technique

[0002] Waste plastics refer to plastic products or materials that have lost their original functions or values after use and are discarded. They have a wide range of sources, including packaging, electronic products, building materials, automotive parts, etc. The treatment and recycling of waste plastics are crucial for environmental protection. Waste plastic cleaning is a key step in the recycling process, aiming to remove impurities (such as oil stains, labels, glue, etc.) to ensure the quality of recycled plastics. The cleaning effect directly affects the subsequent processing and the performance of the final product. When existing waste plastics are recycled and cleaned, traditional waste plastic cleaning has high water consumption, incomplete cleaning, high dependence on labor, and the traditional device has a complex and large structure, frequent failures and difficult maintenance. Therefore, the present utility model proposes a waste plastic cleaning device to solve the problems mentioned in the above background technique. Summary of the Invention

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model features a filter screen filtration + circulating pump reuse design, which significantly reduces water consumption. The filter screen blocks particulate impurities, preventing secondary pollution of the circulating water and reducing wastewater treatment costs. It flattens waste plastics (such as films and bottle flakes), increasing the cleaning contact area and improving rinsing and brushing efficiency. The cam mechanical linkage cleaning brush moves up and down without additional power. Brushing and spraying work together to remove stubborn stains. A single motor drives the flattening roller, cleaning brush, and spray, resulting in a compact structure and reducing potential failure points. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4, A waste plastic cleaning device, including a circulation pool 1 and a disinfection pool 2. The disinfection pool 2 is installed on the front side of the circulation pool 1. A device frame 3 is fixedly installed on the upper side of the circulation pool 1. A number of flattening rollers 4 are rotatably connected to both the left and right inside the device frame 3. A feeding port 5 is provided on the rear side of the device frame 3. A spur gear 6 is fixed to the upper end of the flattening roller 4. The spur gears 6 of two adjacent left and right flattening rollers 4 mesh with each other. On the upper side of the spur gears 6 of a number of flattening rollers 4 on one side of the device frame 3, sprockets 10 are fixed. A corresponding chain 11 is sleeved outside a number of sprockets 10. A driving device is installed inside the device frame 3. The output shaft of the driving device is fixedly connected to a flattening roller 4. The waste plastic to be cleaned is put into the device frame 3 through the feeding port 5. The driving device drives a flattening roller 4 to rotate. When a flattening roller 4 rotates, a number of other flattening rollers 4 follow to rotate through a number of sprockets 10 and the corresponding chains 11. And through two adjacent meshing spur gears 6, the number of flattening rollers 4 on the other side follow to rotate. The number of flattening rollers 4 rotating towards each other on both sides can flatten and push the waste plastic forward;

[0019] Furthermore, circulation pipes 8 are provided on both the left and right sides of the device frame 3. The circulation pipes 8 are fixedly installed in the circulation pool 1. A filter screen 15 installed in the circulation pool 1 is provided on the lower side of the device frame 3. A number of spray nozzles 9 are installed on the circulation pipes 8. The spray nozzles 9 are located between two adjacent flattening rollers 4. A circulation pump 16 connecting the two circulation pipes 8 on both sides is provided inside the circulation pool 1. When the circulation pump 16 in the circulation pool 1 is started, the circulation pump 16 pumps out the water in the circulation pool 1 and sprays it out through the upper spray nozzles 9. Through the gap between the two flattening rollers 4, the waste plastic being flattened and pushed forward is rinsed. The water rinsed down passes through the filter screen 15, which can separate most of the particulate pollutants. The rinsing water flows back into the circulation pool 1, enabling the reuse of the rinsing water;

[0020] Even further, a number of cleaning brushes 12 are provided inside the device frame 3. The number of cleaning brushes 12 are evenly distributed among a number of flattening rollers 4. The cleaning brushes 12 are in a "C" shape and slide up and down inside the device frame 3. During the process of the flattened waste plastic being pushed forward, it passes through the middle of a number of cleaning brushes 12. A connecting frame 7 is fixedly connected to the upper side of the number of cleaning brushes 12. A cam 13 is fixed to the upper side of a spur gear 6. And a sliding shaft 14 corresponding to the cam 13 is fixed to the lower side of one end of the connecting frame 7. During the rotation of the above-mentioned flattening rollers 4, when the cam 13 on the upper side of a flattening roller 4 rotates and the protruding part of the cam 13 comes into contact with the sliding shaft 14, the connecting frame 7 is driven to move the number of cleaning brushes 12 connected to the lower side upward. When the protruding part of the cam 13 has passed by, the cleaning brushes 12 move downward. Cooperating with the number of flattening rollers 4 rotating on both sides and the number of spray nozzles 9 on both sides, it can achieve the efficient and high-quality cleaning of the flattened waste plastic. The flattened waste plastic is also conducive to recycling. The waste plastic after cleaning enters the disinfection pool 2. There is a chemical disinfection agent in the disinfection pool 2, which can disinfect and sterilize the waste plastic.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
