AI Technical Summary
In the current PET plastic recycling process, air separation efficiency is low, and it cannot effectively separate light and heavy bottle body and cap fragments. Especially when separating large quantities, light fragments are easily carried away by heavy fragments, resulting in extremely poor separation effect.
The system employs a two-stage sorting structure, including a vertical sorting group and an inclined sorting group. It combines a bent pipe section and multiple air inlets. The bent pipe section guides the heavy objects to fall and slows down the falling speed of lightweight plastics, while the multiple air inlets improve the separation efficiency.
It effectively improves the separation effect of lightweight and heavy plastic sheets, ensures the purity of the separated fragments, and enhances the separation efficiency of large-volume separation.
