Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drying and relates to a plastic powder drying device. Background Art
[0002] As the consumption of plastic products continues to increase, the amount of waste plastics is also increasing. If the waste plastics are not properly handled, it will inevitably damage the environment and endanger people's health. Waste plastics have extremely high recycling value due to their own characteristics.
[0003] The recycling process of plastics is usually crushing → cleaning → drying → sorting → granulation → pelletizing. After the waste plastics are crushed by a crusher, the waste plastic powder generated will be introduced into a cleaning tank for cleaning to remove impurities such as mud and sand in the waste plastic powder. The cleaned waste plastic powder will then be dried. Existing dryers usually use electric heating to dry plastic powder. However, electric heating can only heat the powder on the surface, and the powder in the inner layer is difficult to dry, which increases the drying time and reduces the drying efficiency. Therefore, we propose a plastic powder drying device. Utility Model Content
