[0018] During operation, the slag inlet gate valve 10 is opened, and the high-temperature slag from the waste incinerator enters the inner side of the outer shell 26 through the slag inlet pipe 11. Subsequently, the drive motor 22 is started. During the rotation of the drive motor 22, the large sprocket 21 is driven to rotate, and then the outer shell 26 rotates. The slag is caught by the transverse ribs 27. Then, as the outer shell 26 rotates, the guide rib fins 18 are spiral rib fins. While driving the slag to roll upward, the guide rib fins 18 cause a slight displacement of the slag to the right. When the slag moves to the upper side, due to the action of gravity, the slag falls to the lower part inside the outer shell 26; the slag is moved to the right side of the outer shell 26; Cooling water is poured in from the cooling water inlet 16, and then the cooling water outlet 15 is closed, so that the cooling water sequentially passes through the cooling water inlet 16, the two-way adapter 17, and the water inlet pipe 14, and then flows into the water collection block 29 from the lower water pipe 12. The cooling water flows in the direction opposite to the movement direction of the slag. During the movement of the slag, the outer shell 26 and the lower water pipe 12 are heated. Finally, the heat is transferred to the cooling water. After the heated cooling water finally fills the water collection block 29, it flows out from the upper support ring 20. Then, the cooling water inlet 16 is closed, and a water pump is externally connected to the cooling water outlet 15 to pump out the heated cooling water from the cooling water outlet 15, and the waste heat utilization of the slag can be completed;

[0019] Since the heat of the slag is absorbed by the outer shell 26, the water pipe 12, and the cooling water in the water pipe 12 during the movement process, the temperature of the slag gradually decreases. Its movement trajectory is generally to the right. Finally, the cooled slag falls into the slag collection block 30. At this time, the slag outlet pipe 25 is opened to take it out.
