At this time, the ratchet 5046 slides on the pawl 5045 to stop the rotary furnace body 4 from rotating. The shaft 503 reverses and drives the first pinion 507 to rotate. The first pinion 507 drives the first belt 509 to rotate. The first belt 509 drives the second pinion 508 to rotate. The second pinion 508 drives the rotating drum 510 to reverse. The rotating drum 510 drives the stirring plate 511 and the scraper plate 512 to rotate, stirring the material inside the rotary furnace body 4 to prevent the material from accumulating at the discharge port 7. The scraper plate 512 scrapes off the material adhering to the inner wall of the rotary furnace body 4 to improve the efficiency of material discharge.

[0031] When the material is discharged from the discharge port 7, the second motor 803 is manually controlled to start, the output shaft of the second motor 803 drives the second rotating shaft 804 to rotate, the second rotating shaft 804 drives the first large gear 805 to rotate, the first large gear 805 drives the second belt 808 to rotate, the second belt 808 drives the second large gear 806 and the third large gear 807 to rotate, and at the same time the water pump 8018 is controlled to start, the water pump 8018 pumps the coolant in the water tank 8019 into the liquid inlet pipe, and enters the coolant cavity formed between the outer cylinder 8011 and the inner cylinder 8016 from the liquid inlet pipe, the coolant returns to the water tank 8019 from the liquid outlet pipe, the second large gear 806 drives the connecting column 8014 to rotate, and the connecting column 8014 is connected to the connecting column 8014. The connecting column 8014 drives the agitator 8013 to rotate, and the blades of the agitator 8013 divide the inner cylinder 8016 into three chambers. When the material enters one of the chambers in the inner cylinder 8016, the agitator 8013 rotates in the direction away from the feed pipe 8012, thereby extending the time for the material to exchange heat with the coolant. When the above-mentioned chamber moves to the discharge pipe 8017, the discharge valve is controlled to be opened for a period of time, and the material in the chamber against the inner wall of the inner cylinder 8016 will enter the discharge box 9 from the discharge pipe 8017. After a period of time, the discharge valve is controlled to be closed, and the material in the chamber away from the inner wall of the inner cylinder 8016 will be driven by the agitator 8013 to continue to rotate and absorb heat, and the above steps are repeated for the materials in other chambers.

[0032] When the material enters the outer shell 8021 from the discharge pipe 8017, the third large gear 807 drives the connecting rod 8023 to rotate, and the connecting rod 8023 drives the fan 8024 to rotate. The airflow is blown from the first filter plate 8025 through the fan 8024 to the second filter plate 8028 to dissipate the heat of the material falling from the discharge pipe 8017. The second filter plate 8028 blocks the material blown to the discharge pipe 8017 to prevent the material from being discharged from the air outlet pipe 8027. After double heat dissipation, the material falls into the discharge box 9, and the cooled material is taken out manually. When all the materials enter the discharge box 9, the cylinder rod of the hydraulic cylinder 205 is controlled to be retracted, and the cylinder rod drives the rotating block 204 to rotate in the flip groove 203. The rotating block 204 drives the flip plate 201 to rotate around the rotating column 202, and the flip plate 201 drives the rotary furnace body 4 to rotate to the initial position.
