Technical Field

[0001] The utility model belongs to the technical field of industrial furnace hot repair, in particular to a hole sealing device for a bottom plate hole of an industrial furnace hot repair. Background Art

[0002] Glass furnace is a kind of melting equipment that is essential for the glass manufacturing industry. During the operation of the glass furnace, the small furnace periodically passes through combustion air or flue gas, and the temperature is always maintained above 1450°C. The small furnace is mainly composed of refractory materials and supporting steel structures. The refractory materials will be eroded and damaged under the combined action of high-temperature flames and other reasons, and need to be repaired under hot conditions. Different maintenance methods need to be adopted according to the different locations of the damaged refractory materials. One of them is to open an operating hole on the bottom plate of the small furnace for hot maintenance operations.

[0003] After the hot repair of the refractory material is completed, the working hole needs to be closed. The current method usually requires covering the upper part of the working hole with bricks. Since the temperature in the entire small furnace channel is over 1450°C, bricks cannot be placed directly. Usually, construction workers use high-temperature insulating gloves to quickly place sealing bricks. However, the current maximum temperature of high-temperature insulating gloves does not exceed 500°C, so each operation will burn the insulating gloves, and the safety factor is low, which is not conducive to workers' operations.

[0004] Therefore, a device for sealing the opening of the bottom plate of an industrial furnace for hot repair is needed to solve the above-mentioned problems. Utility Model Content

[0007] Furthermore, the rotating assembly includes a rotating shaft 1 and a rotating shaft 2. The top of the support rod is fixedly connected to the rotating shaft 1, and the outer side of the rotating shaft 1 is rotatably connected to the rotating shaft 2.

[0008] Furthermore, the second rotating shaft is fixedly connected to the tray, and the second rotating shaft can rotate along the outer side of the first rotating shaft.

[0009] Furthermore, the end surface of the limiting circular tube is in a beveled state, and the limiting circular tube is used to support refractory bricks.
