Description

Technical Field

[0001] The utility model relates to the technical field of resin waste recycling, in particular to a high-efficiency recycling device for PVB resin waste. Background Technique

[0002] Under the background of environmental protection and sustainable utilization of resources, the treatment and recycling technology of PVB resin waste has become the focus of global attention. As an important industrial raw material, PVB (polyvinyl butyral) resin is widely used in fields such as automobiles, construction, and optics. Inevitably, a certain amount of waste will be generated during its production and use. In recent years, with the continuous progress of technology, various PVB resin waste recycling technologies have emerged, mainly including physical recycling, chemical recycling, and biological recycling methods. Among them, physical recycling mainly conducts preliminary treatment on waste through means such as crushing, screening, and washing, and then remakes it into usable products through processes such as melting and calendering; chemical recycling is to convert useful components in waste into other chemical substances through chemical reactions to achieve resource reuse; biological recycling is to use biological catalysts such as microorganisms or enzymes to decompose and transform waste.

[0003] Although the existing PVB resin waste recycling devices can achieve waste recycling and reuse to a certain extent, there are obvious defects in continuous feeding. Specifically, the discharge ports at the bottom of these devices often lack an effective continuous feeding mechanism, resulting in difficulties in forming a smooth and continuous cyclic feeding process for waste discharge and collection during the recycling process, reducing the overall usability of the recycling device. Therefore, we need to propose a high-efficiency recycling device for PVB resin waste. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-efficiency recycling device for PVB resin waste, aiming to solve the problem that the discharge ports at the bottom of the existing recycling devices often lack an effective continuous feeding mechanism, resulting in difficulties in forming a smooth and continuous cyclic feeding process for waste discharge and collection during the recycling process, and reducing the overall usability of the recycling device.

When the PVB resin waste stored in one of the receiving boxes 4 is about to be full, the staff can pull it out along the chute 7. At this time, it can automatically drive another receiving box 4 located behind it to move forward. When the receiving box 4 located behind starts to receive materials, the receiving box 4 located in the front can be disconnected from the receiving box 4 located behind. At the same time, through the arranged locking component 8, the receiving box 4 located behind can be automatically positioned to prevent it from shifting during material receiving, which is beneficial to further improving the material receiving stability.
