The cold air blows into the kiln tail of the tunnel kiln to cool the products in the last section of the tunnel kiln. After the cold air blows in flows through the products and is heated, it is drawn out and sent to the dryer as a heat source for drying the green body. This section constitutes the tunnel. The cooling zone of the kiln; in the use of the existing tunnel kiln, the track structure used by the tunnel trolley is fixed, and only a single type of tunnel trolley can be used for the transportation of goods. There are certain limitations in use, and the internal structure of the tunnel kiln is fixed. The temperature during heating is fixed and cannot be adjusted, and the use effect is general

The invention discloses a high-temperature tunnel kiln structure. The high-temperature tunnel kiln structure comprises a kiln body, wherein a main heat conducting pipe is arranged on the kiln body, the main heat conducting pipe is connected with a branch heat conducting pipe, a heat conducting layer is fixedly installed on the inner side of the kiln body, a cavity is formed in the heat conductinglayer, first heat transfer pipes are arranged at the lower end of the main heat conducting pipe, and connecting pipes are connected with the tail end of the branch heat conducting pipe. The high-temperature tunnel kiln structure belongs to the field of tunnel kilns. Guide groove structures and guide rail structures are arranged, so that the high-temperature tunnel kiln structure is suitable for tunnel trolleys of different models, the flexibility of a tunnel kiln during use is improved, and the practicability is improved; protective structures are arranged in the guide groove structures, so that the stability of rollers directly colliding with the groove side walls can be avoided, the stability of a tunnel trolley during movement can be avoided, and meanwhile the impact force is reduced; by arranging heat conducting structures, the heat conducting structures can be removed when heat conduction is guaranteed, and the use flexibility is improved; and meanwhile, the clamping manner is adopted during installation, the structure is simple, and the operation is quick.
Description
technical field [0001] The invention relates to the field of tunnel kilns, in particular to a high-temperature tunnel kiln structure. Background technique [0002] The tunnel kiln is a kiln similar to a tunnel, which is built of refractory materials, thermal insulation materials and building materials, and is equipped with kiln cars and other vehicles. It is a modern thermal equipment for continuous firing. Tunnel kilns are widely used in the roasting production of ceramic products, and are also used in metallurgical industries such as abrasives. Among them, the latest tunnel kiln designed in Leningrad, Russia is more advanced. Tunnel kiln is generally a long linear tunnel with fixed walls and vaults on both sides and top, and kiln cars run on tracks laid at the bottom. The combustion equipment is installed on both sides of the middle part of the tunnel kiln, which constitutes a fixed high-temperature zone - the firing zone. The high-temperature flue gas generated by combu...
