[0002] The existing high temperature heater heat preservation layer structure has two forms, the first is multi-section (usually six sections) series connection, the outermost layer adopts the soft aluminosilicate needle blanket with the thickness of 10mm to fill gap heat insulation, the defect is that heat is transferred to the furnace shell by the gap of the rigid aluminosilicate heat insulation material, according to the heat conduction formula Q transmission=λ (t2-t1) / σ thickness, the aluminosilicate needle blanket with 10mm thickness is thinner, which leads to a large amount of heat transfer to the furnace shell, causing heat dissipation, and further leading to the increase of heating energy consumption. The second is the overall high temperature heater, the aluminosilicate needle blanket is cut, and the segmented splicing is covered outside the high temperature heater. The principle of flexible aluminosilicate needle blanket heat preservation is that a large number of air hole warehouses in the needle blanket are heat insulated and the ceramic fiber heat transfer anisotropy is heat insulated. The ceramic fiber and air hole warehouse at the cutting seam of the cut aluminosilicate needle blanket are damaged, which destroys the anisotropic heat insulation ability of the ceramic fiber needle blanket, resulting in a large amount of heat energy being dissipated by convection through the cutting seam of the aluminosilicate needle blanket, thereby reducing the heat insulation and heat preservation ability of the aluminosilicate needle blanket. Therefore, the heat preservation layer assembly structure of high temperature heater is proposed to solve the above problems. SUMMARY
