Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a device for dehydrating recycled plastic particles. Background Art

[0002] Plastics are widely used in various fields of people's lives due to their excellent plasticity. While we enjoy the convenience brought by plastic products, we also produce a large amount of plastic waste. Plastics are derived from petroleum processing and are essentially non-renewable resources. Not only that, plastic waste is extremely easy to pollute the environment due to its own difficult degradation. Therefore, the control of plastic waste is very important. Plastic waste is generally recyclable waste. The recycled plastic is called recycled plastic. The recycled plastic needs to be cooled after melting and drawing, and the plastic particles also need to be cooled after they are finally produced.

[0003] After searching, it was found that the publication number is CN211807188U, and the name is a high-hardness recycled plastic cooling and dehydration device. The application proposes that many existing processing plants directly place the strands or particles into water or directly contact the water body for cooling and dehydration, then cut into pellets and repeat the above steps for storage. This exposes two problems. First, the two processes consume a lot of time cost, and also make the strands or particles susceptible to unnecessary damage and loss during the work process; second, some characteristic plastic particles are not suitable for processing in this way, such as high-hardness plastics. This type of plastic already has a certain hardness and strength at this time. The traditional cooling method will make the particles stick to water, and the centrifugal dehydration method commonly used in the industry will cause the particles to be damaged by impact. The high-hardness recycled plastic strips or plastic particles produced by the molten strands are sent one by one into the cooling pipe in the equipment to the device. The inside of the tank is filled with water to a horizontal level close to the tank mouth, the sealed tank is covered, and the hanging buckle is fastened. After the sealed tank motor is energized, the motor drives the turntable to rotate at a high speed, and the pull rods or particles in the cooling tube are fully cooled through the heat conduction effect. When dehydration is required, the cooling tube is pulled out, the side door is opened, and a drain hose is inserted into the through hole to guide the water to the water storage device for recycling. The centrifugal force of the high-speed rotation of the motor is started to dry the water. Although the device will also perform centrifugal dehydration during implementation, it will not cause the plastic particles to collide violently with each other and be damaged. However, the application still uses the traditional centrifugal dehydration method during dehydration. Although the collision problem is solved, it causes the problem of extremely inconvenient loading and unloading, and the operation is cumbersome and difficult. At the same time, centrifugal dehydration relies on centrifugal force for dehydration. In order to achieve the ideal dehydration effect, a long period of rotation dehydration is required, which affects the production efficiency. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
