Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, this utility model provides a technical solution: a tunnel furnace insulation structure, including an inner layer of insulation board 1 and an outer layer of insulation board 2. The area inside the inner layer of insulation board 1 is the inner liner 5. For tunnel furnaces, the inner liner generally has a higher temperature, while the outer wall is the operating area with a lower temperature. Insulation cotton is filled between the outer wall and the inner liner for heat insulation and protection, forming the heating area. The inner layer of insulation board 1 and the outer layer of insulation board 2 have reserved space for installing a heat insulation layer 3. The heat insulation layer 3 includes an inner layer of insulation cotton 301 and an outer layer of insulation 302. The inner layer of insulation cotton 301 is made of soft ceramic fiber insulation cotton, which has better heat resistance and can withstand temperatures above 1000°C. The outer layer of insulation 302 is made of high-density rock wool board. High-density rock wool boards are used, which have good shaping and support functions. The inner insulation cotton 301 is set tightly against the inner sealing cotton board 1, and the outer insulation layer 302 is set on the outside of the inner insulation cotton 301. The outer insulation layer 302 is composed of multiple layers of insulation cotton and uses two different insulation materials. The inner insulation cotton 301 is soft ceramic fiber cotton, which better fits the outer surface of the inner liner. Then, several layers of hard high-density rock wool are laid outward from the inner insulation cotton 301. In order to better insulate heat, the support layers are staggered and overlapped, and the seams of the insulation cotton boards are staggered. The outer rock wool boards have high strength and can be used as support cotton to support the outer sealing cotton board well. At the same time, the structure is stable and not easily deformed when the equipment vibrates.

[0027] Please refer to the following carefully. Figure 3 , Figure 4 and Figure 5 The insulation cotton includes two layers of insulation cotton 3021, three layers of insulation cotton 3022, four layers of insulation cotton 3023 and five layers of insulation cotton 3024, and the adjacent insulation cotton is laid in a staggered and cross manner to avoid continuous through seams. The two layers of insulation cotton 3021, three layers of insulation cotton 3022, four layers of insulation cotton 3023 and five layers of insulation cotton 3024 are all divided into upper, lower, left and right parts.

[0028] Please refer to the following carefully. Figure 5 Aluminum foil 4 is laid between the second layer of insulation cotton 3021, the third layer of insulation cotton 3022, the fourth layer of insulation cotton 3023 and the fifth layer of insulation cotton 3024. The installation of aluminum foil 4 can greatly improve the insulation performance. During the construction of insulation cotton, the aluminum foil can be applied to a flat surface to further strengthen the seal.

[0029] Working principle: This utility model uses two different insulation materials. The inner insulation cotton 301 is soft ceramic fiber cotton, which better fits the outer surface of the inner liner. Then, several layers of hard high-density rock wool are laid outward from the inner insulation cotton 301. In order to better isolate heat, the support layers are staggered and overlapped, and the seams of the insulation cotton boards are staggered. The outer rock wool boards have high strength and can be used as support cotton to support the outer sealing cotton board well. At the same time, the structure is stable and not easily deformed when the equipment vibrates.
