[0021] Specifically, the hot gas separation mechanism includes a hot gas adsorption box 4, a circulating fan 5, an exhaust pipe 6, an aeration pipe 7, multiple ventilation pipes 8, and an exhaust pipe 9. The hot gas adsorption box 4 is located above the conveyor belt 1 and is fixed to the outer shell of the conveyor belt 1. The circulating fan 5 is fixedly installed on the top of the hot gas adsorption box 4. One end of the exhaust pipe 6 is fixedly connected to the air inlet of the circulating fan 5, and the other end of the exhaust pipe 6 is fixedly connected to the top of the hot gas adsorption box 4.
