The cylinder and partition frame adopt water-cooled wall structure. Slag guide plates are welded on the inner wall of the cylinder and the partition frame. The high-temperature slag discharged from the boiler is guided forward by spiral blades in the inner cylinder of the sleeve. The cooling water flows in the reverse direction in the jacket between the inner and outer cylinders to take away the heat. The cooling wind also continuously passes through the inner cylinder of the jacket to take away the heat, so that the slag is gradually cooled and the heat of the slag can be recycled.

[0003] The slag cooler in the prior art has the following disadvantages: 1. When the slag is transported into the slag cooler for heat exchange, some of the slag is combined to form large pieces of slag. During the continuous heat exchange process, the heat of the slag inside is relatively high, and it is not easy to exchange heat with the outside, which affects the heat exchange effect; 2. During the continuous heat exchange process of the slag cooler, the machine body continues to dissipate heat outward when it comes into contact with the outside air, causing partial heat loss. Therefore, improvements are made to address the above problems. Utility Model Content
