Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation, in particular to a composite thermal insulation board. Background Art

[0002] Refractory insulation materials are essential thermal insulation materials for industrial furnaces and thermal equipment. Their purpose is to slow the rate of heat loss during high-temperature operation, thereby saving energy. Therefore, refractory insulation materials are widely used in furnaces and thermal equipment in fields such as metallurgy, machinery manufacturing, and chemical engineering.

[0003] Currently, the application of a single insulation material has limitations. For example, refractory bricks, thanks to their excellent high-temperature resistance, perform well in high-temperature environments, but their insulation effectiveness is relatively poor. Conversely, aerogel insulation boards offer excellent insulation, but their fire resistance is relatively weak. Therefore, using a single insulation material for overall insulation not only incurs high material costs but also struggles to achieve ideal insulation across a wide range of temperatures, failing to meet complex and changing insulation needs.

[0004] Therefore, it is necessary to propose a composite insulation board to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-2 As shown, a composite thermal insulation board includes an aerogel insulation layer 2 and a multi-layer thermal insulation layer 4 connected in sequence, and the aerogel insulation layer 2 and the thermal insulation layer 4, as well as the two adjacent thermal insulation layers 4, are plugged into each other; the working temperature zones of the aerogel insulation layer 2 and the multi-layer thermal insulation layer 4 increase in sequence along the connection sequence, and the temperature of the aerogel insulation layer 2 and each thermal insulation layer 4 on the side close to the working surface to be insulated is adapted to its working temperature zone.

[0024] By utilizing the advantageous working temperature zones of different refractory insulation materials, efficient and economical insulation effects can be achieved. In addition, the insulation layers are connected by plugging to increase their contact area, making the connection between different materials more stable and avoiding stratification and dislocation.

[0025] In some embodiments, the thermal insulation layer 4 comprises two layers, specifically a first insulation layer and a second insulation layer. During use, the first insulation layer is placed close to the object being insulated, and the temperature is continuously attenuated by the first insulation layer, so that the temperature on the side of the first insulation layer close to the second insulation layer matches the operating temperature range of the second insulation layer. The temperature is then further attenuated by the second insulation layer, so that the temperature on the side of the second insulation layer close to the aerogel insulation layer 2 matches the operating temperature range of the aerogel insulation layer 2.

[0026] Specifically, the thermal insulation layer 4 is made of ceramic fiberboard, lightweight insulation brick, calcium silicate board, microporous nano insulation board or rock wool board. The multi-layer thermal insulation layer 4 uses different materials so that the working temperature range of each layer of the thermal insulation layer 4 meets the design requirements.

[0027] In some embodiments, a slot 5 and an insert 6 are respectively provided on the side where the aerogel insulation layer 2 contacts the thermal insulation layer 4 and the side where two adjacent thermal insulation layers 4 contact each other, and the slot 5 and the insert 6 are adapted to each other.

[0028] By providing the slots 5 and the inserts 6, the various insulation layers can be effectively fixed to prevent them from being displaced or falling off due to external forces during use. Specifically, the cross section of the slots 5 is trapezoidal, rectangular, triangular or fan-shaped. Preferably, the slots 5 have gradually converging notches. For details, please refer to Figure 2 As shown, the cross section of the slot 5 is an inverted trapezoid, and the slot 5 and the insert 6 are interlocked to further improve the connection strength.

[0029] Specifically, a high-temperature resistant adhesive layer 3 is provided between the aerogel insulation layer 2 and the thermal insulation layer 4, and between two adjacent thermal insulation layers 4. The high-temperature resistant adhesive layer 3 provides a more stable connection. In addition, the cooperation between the slot 5 and the insert 6 can increase the contact area, further improving the bonding effect.

[0030] In some embodiments, a protective layer 1 is provided on a side of the aerogel insulation layer 2 away from the thermal insulation layer 4. Preferably, the protective layer 1 is aluminum foil, which is bonded and fixed to the aerogel insulation layer 2. The aluminum foil is provided to protect the aerogel insulation layer 2 and increase its surface strength.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
