Description

Technical Field

[0001] This utility model belongs to the technical field of thermal insulation modules, specifically relating to a large thermal insulation module. Background Technology

[0002] The outer shell of a bogie furnace is generally welded from steel plates and structural steel. The furnace lining material is constructed using ultra-lightweight, energy-saving, refractory, and heat-insulating bricks, forming a structural layer of highly heat-resistant insulating material. This layer isolates the radiant heat from the furnace chamber, reduces the temperature of the furnace's outer surface, and decreases the energy dissipated from the furnace's outer surface. For example, patent CN214406930U discloses a gas-fired device with good insulation performance. The structural layer is fixed inside the furnace by an installation structure. For example, patent CN115247805A discloses a movable dome structure and construction method for a combustion furnace, using supporting components to fix the insulation layer and refractory layer.

[0003] Existing furnace insulation blocks are made by attaching high-temperature resistant fiber blankets to the surface of existing insulation blocks, or by using high-temperature resistant fiber blankets for the entire insulation block. This results in low strength of the insulation blocks, leading to a reduction in block size to meet installation strength requirements. In other words, furnace insulation blocks are all small modules, with specific dimensions not exceeding 600mm in length, 300mm in width, and 300mm in thickness. The assembled structural layers have numerous seams and poor flatness. Utility Model Content

[0012] 1. The double-layer fiber blanket is arranged in combination, which, under the condition of meeting the strength and durability of the material, reduces the material cost on the one hand and improves the appearance on the other hand, greatly improving the applicability and stability in the process of the industrial furnace body.

[0013] 2. The high-temperature-resistant fiber blanket is fixed by the round tube to prevent deformation, and the low-temperature-resistant fiber blanket is fixed by the round rod to enhance the overall strength of the heat preservation block, improve the upper limit of the size of the heat preservation block, enable the large heat preservation block to be made, reduce the splicing joint and improve the flatness.
