[0023] refer to Figure 1 , Figure 2 and Figure 3 , is a stepping furnace bottom sewage discharge assembly provided in this example, the furnace bottom 1 is provided with a sewage discharge pipe 2, and the sewage generated when the stepping furnace is working is discharged from the sewage discharge pipe 2; the sewage discharge assembly is arranged at the sewage outlet of the sewage discharge pipe 2, and the sewage discharge assembly includes a sealing blind plate 3 covered in the sewage outlet and a control member 4 for controlling the opening and closing of the sealing blind plate 3, and one side of the sealing blind plate 3 is hinged on the sewage discharge pipe 2 through a hinge; the control member 4 includes a driving cylinder 41 and a bearing rod 42 arranged on the sewage discharge pipe 2, the top end of the driving cylinder 41 is hinged on the bearing rod 42, and the telescopic end of the driving cylinder 41 is provided with a connecting rod 43 that is perpendicular and hinged thereto, and one end of the connecting rod 43 extends to the lower end surface of the sealing blind plate 3 and is fixedly connected by bolts. When the stepping furnace needs to discharge the sewage generated inside after working for a period of time, the sealing blind plate 3 is driven to open by the driving cylinder 41 at this time, and the sewage is discharged from the sewage discharge outlet; when the sewage is discharged, the sealing blind plate 3 is driven by the driving cylinder 41 to seal the sewage discharge outlet. When the telescopic end of the driving cylinder 41 is extended, the sealing blind plate 3 seals the sewage outlet; otherwise, the sealing blind plate 3 is opened.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The upper end surface of the sealing blind plate 3 is provided with a sealing block 5 embedded in the sewage outlet, and a sealing ring 6 is sleeved on the outer edge surface of the sealing block 5.
