Description

Technical Field

[0001] The utility model relates to the technical field of triboelectric high-voltage electrostatic separation devices for plastic particles, in particular to a triboelectric high-voltage electrostatic separation device for plastic particles. Background Art

[0002] Plastic products can be seen everywhere in our lives. While plastics provide convenience to people, they also cause tremendous pressure on the environment. With the widespread use of plastic products in my country, there are more and more waste plastic products. Waste plastics are not easy to degrade. There are no bacteria and enzymes in nature that can degrade plastics. The incineration of waste plastics will produce a large amount of harmful gases, and the burial of waste plastics will seriously affect the ecological environment. Only by recycling and reusing waste plastic products can we achieve sustainable development and save natural resources. However, the composition of waste plastics is complex, and there are often multiple plastics, rubbers, metals and other impurities mixed together, which cannot be used directly. Separating plastic waste mixed with multiple plastics into single plastic components can greatly improve their reuse value, reduce environmental risks, and create huge economic benefits. In the process of plastic particle sorting, a plastic particle friction charging high-voltage electrostatic sorting device is required for material unloading;

[0004] There may be two problems when using it. First, during the unloading process, the device only drives the conveyor belt to vibrate through the vibration motor, which makes the vibration range small and generates large noise. After the unloading is completed, the staff needs to clean the conveyor belt regularly; second, when the device unloads through the feed pipe below, its fan can easily cause the raw materials to flow back to the inside of the feed pipe, making it prone to blockage. Therefore, we proposed a plastic particle friction charging high-voltage electrostatic sorting device. Utility Model Content
