[0028] In this embodiment, during processing, the thin aluminum sheets are placed in the discharge port 7, and the blower 21 is started. The output shaft of the blower 21 drives the large pulley 23 to rotate, and the large pulley 23 drives the small pulley 24 to rotate through the toothed belt. The small pulley 24 drives the rotating rod 25 inside the distribution bin 1 to rotate, and the rotating rod 25 drives the distribution plate 26 to send the thin aluminum sheets entering from the feeding port 27 into the guide bin 2 below. This can avoid the accumulation of materials in the guide bin 2, and the separate transportation can make each thin aluminum sheet heated evenly.

[0029] like Figure 2 As shown, a waste heat recovery mechanism is arranged between the combustion furnace 3 and the outside of the guide bin 2, and the waste heat recovery mechanism includes a shell 13 and a shell 2 14.

The small pulley 24 drives the rotating rod 25 inside the distribution bin 1 to rotate, and the rotating rod 25 drives the distribution plate 26 to respectively send the thin aluminum sheets entering from the feeding port 27 into the guide bin 2 below, so that the materials can be prevented from accumulating in the guide bin 2, and the separate transportation can make each thin aluminum sheet heated evenly; after the aluminum sheets are separately transported, they are gradually heated and melted by the electromagnetic heater 5 during the process of falling in the guide bin 2 and the cone bucket 4. When the aluminum sheets are completely melted, the aluminum liquid is led out to the insulation furnace 6 through the cone bucket 4; when the blower 21 is started, the liquid aluminum produced during combustion will also be The generated exhaust gas is sent into the air delivery pipe 28 from the exhaust pipe 20, and is mixed with the air inside the air inlet 11 and then burned by the burner 8. During the combustion of the exhaust gas, the cooling water entering from the water inlet 18 flows along the serpentine tube 15, and cools the exhaust gas generated after the combustion, and finally is filtered through the activated carbon filter 12 and discharged.
