[0042] Working Principle: The blast furnace cooling plate consists of a first cooling plate 10, a second cooling plate 11, and a third cooling plate 12, which are tightly connected and fixed to the inner wall of the blast furnace through a connecting structure. The connecting structure includes a connecting portion and a reinforcing portion. The connecting portion presses the third cooling plate 12 against the inner wall of the blast furnace through an arc-shaped pressure plate 21 and a damping spring rod 20; the reinforcing portion firmly connects the cooling plates and the cooling plates to the inner wall of the blast furnace through components such as a first fixing plate 13, a second fixing plate 15, a third fixing plate 17, and a first limiting bolt 19. Cooling water flows through a cooling pipe 31 in a storage tank 30 inside the insulation layer plate 27, acting as a cooling medium to remove heat from the interior of the blast furnace. The heat from the interior of the blast furnace is then transferred to the cooling water through the cooling plates. Because the cooling plates are in close contact with the inner wall of the blast furnace and are securely connected via reinforcement, the heat transfer efficiency is high. A second clip plate 24 is provided inside the second cooling plate 11, and a second air permeable frame plate 25 is fixedly mounted thereon. A hole is provided inside the third cooling plate 12, and a first air permeable frame plate 22 is fixedly mounted thereon. The second air permeable frame plate 25 is in close contact with the first air permeable frame plate 22, forming a cold air transmission channel. Through the air permeable frame plate, cold air can be transferred between the cooling plates and between the cooling plates and the inner wall of the blast furnace, further reducing the temperature inside the blast furnace. The insulation layer plate 27 is placed inside the first cooling plate 10, and a storage slot 30 is provided inside it for accommodating the cooling pipe 31. The insulation layer plate not only improves cooling efficiency but also reduces heat loss. A limiting ring plate 32 is provided on top of the first cooling plate 10 and is connected to the insulation layer plate 27 via components such as the third clip plate 35, a second limiting bolt 37, and a knob cover plate 34. The limiting ring plate can further fix the thermal insulation layer plate to prevent it from falling off or shifting.
