Description

Technical Field

[0001] The invention belongs to the technical field of intelligent sorting of wind power blade recycling, and specifically relates to an intelligent sorting system. Background Technique

[0002] During the recycling process of thermosetting composites, especially during the recycling process of wind power blades, sorting equipment is often required for impurity removal and classification applications. Different sorting equipment is used due to the difference in the shape of impurities. By using limited equipment to achieve multiple sorting functions, the work efficiency of recycling thermosetting composites is improved, and the overall investment cost of the equipment is reduced.

[0003] During the recycling process of wind power blades, two types of materials will be output from the crushing system, and the two materials appear exclusively without mixing; one is the material containing core material, and the other is the material without core material; the specific gravities of the two materials are different, and the specific gravity of the material containing core material is about one-third of the specific gravity of the material without core material. The material containing core material includes three components: core material, fiberglass, and structural adhesive. The components without core material are fiberglass and structural adhesive; when the material without core material is prepared into fiberglass fiber bundles, the color of the fiber bundles is white, while the color of the impurity structural adhesive is non-white. At this time, impurity sorting can be carried out through color. When extracting the material containing core material, the fiberglass material is not completely crushed, and its color is similar to that of the structural adhesive impurity. However, at this time, the structural adhesive is in granular form while the fiberglass material is in sheet form, and sorting can be carried out through shape selection. Summary of the Invention
