A recycling device for laminar structures bonded by cured adhesive, comprising:
- a holder, configured to accommodate a plurality of laminar structures;
- a barrel, having a recycling space for accommodating the holder;
- a molten salt container, for containing a molten salt;
- a first heating device, connecting with the molten salt container for heating the molten salt contained in the molten salt container;
- a pumping equipment, connecting with the molten salt container and the barrel, for injecting the molten salt contained in the molten salt container into the recycling space of the barrel, and pumping the molten salt contained in the recycling space back to the molten salt container;
- a second heating device, connecting with the barrel, for heating the molten salt contained in the recycling space of the barrel;
- a transfer device, for transferring the holder together with the laminar structures into or out of the recycling space of the barrel;
- and
- a control equipment, electrically connecting with the first heating device, the pumping equipment, the second heating device and the transfer device;
- wherein the control equipment provides a plurality of control functions comprising:
- controlling the first heating device to heat and melt the molten salt contained in the molten salt container;
- controlling the transfer device to move the holder together with the laminar structures into the recycling space when a liquid-level of the molten salt in the recycling space of the barrel is lower than a predetermined low liquid-level;
- when the holder and the laminar structures are already in the recycling space, controlling the pumping equipment to inject the molten salt contained in the molten salt container into the recycling space until the liquid-level of the molten salt contained in the recycling space of the barrel reaches a predetermined high liquid-level;
- controlling the second heating device to heat and maintain the molten salt in the recycling space of the barrel at a predetermined processing temperature;
- when the liquid-level of the molten salt injected into the recycling space reaches the predetermined high liquid-level, the control equipment starts timing a predetermined processing time, and after the predetermined processing time ends, the control equipment controls the pumping equipment to pump the molten salt in the recycling space back to the molten salt container when the holder and the laminar structures are still located in the recycling space, until the liquid-level of the molten salt in the recycling space is lower than the predetermined low liquid-level;
- and
- when the predetermined processing time ends and the liquid-level of the molten salt in the recycling space is lower than the predetermined low liquid-level, the control equipment controls the transfer device to move the holder together with the laminar structures out of the recycling space of the barrel;
- wherein, the predetermined low liquid-level is lower than bottoms of the laminar structures accommodated in the recycling space of the barrel;
- the predetermined high liquid-level is higher than tops of the laminar structures accommodated in the recycling space of the barrel.
