Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature fans, and more specifically, to an ultra-high-temperature resistant thermal insulation layer structure. Background Art

[0002] High-temperature fans are widely used in high-temperature working conditions such as chemical industry, machinery, forging, kiln, etc. The fans mainly play the role of hot air collection, circulation, mixing and transportation in the system. Ultra-high temperature fans generally operate at 400-1000℃. The high-temperature airflow passing through the fan will have a huge impact on the ambient temperature, electrical components, mechanical components and personnel safety. Therefore, a good thermal insulation layer is essential for high-temperature fans. When imported fans transport high-temperature gas, the insulation layer thickness is generally 300-350mm.

[0003] After searching, the Chinese patent with the publication number CN217950725U discloses a high-temperature fan for industrial production with a thermal insulation layer. The solution mentions the thermal insulation layer structure on the high-temperature fan.

[0004] However, the above-mentioned insulation layer structure is designed to be installed on the inner wall of the heat output pipe. The disadvantage of this insulation layer installation method is that it is inconvenient to construct. Since it needs to fit on the inner wall of the pipe, it is inconvenient to install the insulation layer. In addition, the diameter of the heat channel arranged in the internal space of the pipe itself is limited. If it is a simple insulation layer, a very thick insulation layer structure is required for the transmission of ultra-high temperature hot air, which will affect the hot air transmission efficiency of the fan itself. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an ultra-high temperature resistant thermal insulation layer structure.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an ultra-high temperature resistant insulation layer structure, comprising an insulation layer main body installed on the outer wall of a pipe shell, wherein the insulation layer main body is composed of an aluminum silicate felt layer, an aerogel felt layer, a rock wool layer, a vacuum insulation layer, a reflective layer, a moisture-proof layer and an outer coating layer, wherein the aluminum silicate felt layer is adhered to the outer wall of the pipe shell, and the aerogel felt layer, rock wool layer, vacuum insulation layer, reflective layer, moisture-proof layer and outer coating layer are arranged in sequence on the outside of the aluminum silicate felt layer.

[0007] As a further improvement of the technical solution of the present utility model, the thickness of the aluminum silicate felt layer is 25-30 mm.

[0008] As a further improvement of the technical solution of the present utility model, the aerogel felt layer is composed of four layers of aerogel felt, the thickness of each layer of aerogel felt is 5-10 mm, and the overall thickness of the aerogel felt layer does not exceed 40 mm.

[0009] As a further improvement of the technical solution of the present utility model, the thickness of the rock wool layer is 25-30 mm.

[0010] As a further improvement of the technical solution of the present invention, the thickness of the vacuum insulation layer is 10-15 mm, and the vacuum insulation layer as a whole is a vacuum insulation cavity structure composed of multiple layers of film and a supporting structure.

[0011] As a further improvement of the technical solution of the present invention, the reflective layer is a component made of an aluminum-plated film material, and the thickness of the reflective layer is 2-4 mm.

[0012] As a further improvement of the technical solution of the present invention, the moisture-proof layer is made of a polymer waterproof and breathable membrane material, and the thickness of the moisture-proof layer can be 2-3 mm.

[0013] As a further improvement of the technical solution of the present utility model, the outer covering layer is a component made of metal aluminum or high-temperature resistant plastic material, and the thickness of the outer covering layer is 8-10 mm.
