Description

Technical Field

[0001] This utility model relates to a heat insulation shield for furnace shells, and belongs to the technical field of heat insulation shields. Background Technology

[0002] A "heat shield" is a protective barrier or panel specifically designed to protect internal structures, equipment, or personnel from heat damage in extreme high-temperature environments.

[0003] Chinese Patent Publication No. CN 222747745 U discloses a composite heat insulation board structure for kilns, including a heat insulation board arranged between the working lining and the metal shell of the kiln, and a support body with a compressive strength greater than that of the heat insulation board. The heat insulation board surface has through holes for the support body in its normal direction, and the support body is fixedly inserted into these through holes; or the support body is located in the through holes, with a distance between the end face of the support body and the surface of the heat insulation board, and the through holes are filled with fire clay located at both ends of the support body to fix it in place. This composite heat insulation board structure for kilns ensures that the heat insulation board is not compressed, or reduces the amount of compression, thus ensuring that the overall thermal insulation performance of the composite heat insulation board structure for kilns is not reduced or only minimally reduced. When assembling the insulation panels, they can only be installed individually through the plug holes. However, this individual installation results in large gaps at the joints between the insulation panels, which prevents them from providing complete insulation and affects their performance.

[0004] Therefore, a heat insulation shield for the furnace shell is proposed. Utility Model Content
