[0002] At present, the slag cooler is also called slag cooler. The slag cooler is mainly composed of a cylinder, a slag inlet box, a slag outlet box, a power transmission device, a base frame and an electrical control system. The cylinder and the partition frame are both water-cooled wall structures.

[0003] When the slag cooler is working, the inner guide wheel assembly needs to be placed in the water body. The sealing performance of the inner guide wheel assembly determines the working efficiency of the slag cooler. Impurities and water in the existing water body can easily enter the inner guide wheel assembly, causing the inner guide wheel to be blocked, resulting in jamming. The inner guide wheel is generally sealed by a sealing gasket or a cover plate, which is prone to friction during long-term use, thus affecting normal use.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created.
