Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling technology, specifically relating to a plastic sheet air separation device. Background Technology

[0002] Plastic recycling is a crucial link in resource recycling. During the recycling and processing of plastic waste, the crushed plastic sheets often vary in size, weight, and specifications, and may also contain impurities such as dust and debris, directly affecting the quality of subsequent recycling. Therefore, efficient sorting of plastic sheets is an indispensable step in the recycling process. Air classifiers, as commonly used equipment for plastic sorting, utilize the principle of airflow separation and the difference in suspension velocity of different materials under the action of wind to quickly separate plastic sheets from impurities or plastic particles of different densities. They feature high sorting efficiency, simple operation, and low energy consumption, providing strong support for the large-scale and refined processing of plastic recycling.

[0003] Existing air classifiers for plastic recycling have significant limitations. The receiving areas for grading materials of different sizes are fixed after manufacturing, and the number and position of grading zones cannot be adjusted. For example, most machines are pre-set with four fixed grades: large, medium, and small plastic flakes, and dust and impurities, making it difficult to adapt to the diverse needs of actual recycling. When recycling requirements are high, necessitating finer grading of plastic flakes, or when requirements are lower, the fixed grading design cannot flexibly adapt, limiting the equipment's applicability. This non-adjustable characteristic makes air classifiers unable to handle the sorting needs of different scenarios, affecting the flexibility and adaptability of plastic recycling to some extent. Therefore, a new air classifier device needs to be designed to solve this problem. Utility Model Content
