[0021] like Figure 1-2 As shown, a thermal insulation structure with ceramic nanofibers includes a furnace body 1, and the thermal insulation structure includes an outer insulation brick 2 and an inner insulation brick 3. The outer insulation brick 2 and the inner insulation brick 3 are both arranged on the inner side of the furnace body 1, and there is a gap between the outer insulation brick 2 and the furnace body 1 to form a first cavity 7, and the two are connected by multiple groups of fixed components, and there is a gap between the outer insulation brick 2 and the inner insulation brick 3 to form a second cavity 8, and the outer insulation brick 2 and the inner insulation brick 3 are connected by multiple connecting columns 9.

[0022] Specifically, the first cavity 7 between the outer insulation brick 2 and the furnace body 1 and the second cavity 8 between the outer insulation brick 2 and the inner insulation brick 3 can reduce heat transfer and increase thermal insulation performance. The outer insulation brick 2 is fixed and supported by a fixing component, and the outer insulation brick 2 and the inner insulation brick 3 are connected to each other through multiple connecting columns 9.

[0023] Furthermore, both ends of each connecting column 9 are fixedly connected with limiting plates 10, and the limiting plates 10 are respectively embedded in the outer insulation brick 2 and the inner insulation brick 3.

[0024] Specifically, the limiting plate 10 between the two ends of the connecting column 9 is embedded in the outer insulation brick 2 and the inner insulation brick 3, connecting the outer insulation brick 2 and the inner insulation brick 3 while preventing them from detaching. At the same time, the limiting plate 10 is embedded in the outer insulation brick 2 and the inner insulation brick 3 so that the side of the inner insulation brick 3 facing the center of the furnace remains intact, reducing holes, further reducing heat transfer, and improving thermal insulation performance.

[0025] Furthermore, the fixing assembly includes a supporting plate 4 and a connecting plate 5. The connecting plate 5 is provided with a mounting hole 6 for fasteners to pass through. The supporting plate 4 is fixedly connected to one edge of the connecting plate 5, and a groove adapted to the supporting plate 4 is provided on the outer insulation brick 2.

[0026] Specifically, when installing multiple groups of outer insulation bricks 2 and inner insulation bricks 3, fixed components are installed on both sides of the outermost outer insulation bricks 2, and a fixed component on one side is installed between two adjacent groups of outer insulation bricks 2 and inner insulation bricks 3 to support the outer insulation bricks 2 on both sides.

[0027] Furthermore, ceramic refractory fiber blanket layers 11 are provided on both sides of the outer insulation bricks 2 and the outer sides of the inner insulation bricks 3. The ceramic refractory fiber blanket layers 11 wrap the outer insulation bricks 2 and one side of the inner insulation bricks 3 to improve the thermal insulation performance.

[0028] Furthermore, the fastener is a bolt, and the bolt is threadedly connected to the furnace body 1 to fasten the connecting plate 5. When the bolt passes through the mounting hole 6 to fasten the connecting plate 5, the supporting plate 4 can be fastened.

[0029] Furthermore, the furnace body 1 , the outer insulation bricks 2 and the inner insulation bricks 3 are all annular, and the fixing components and the connecting columns 9 are evenly arranged along the circumference of the outer insulation bricks 2 and the inner insulation bricks 3 .

[0030] Specifically, the annular outer insulation bricks 2 and the inner insulation bricks 3 can adapt to the cylindrical furnace body 1, and the outer insulation bricks 2 and the inner insulation bricks 3 can also be rectangular to adapt to furnace bodies 1 of different shapes.

[0031] In the above structure, when the heat-insulating structure needs to be installed in the furnace body 1, first install a plurality of supporting plates 4 on one side of the outer insulation brick 2, and then place the outer insulation brick 2 together with the inner insulation brick 3 on the supporting plates 4. At this time, the supporting plates 4 are inserted into the grooves on the outer insulation brick 2 that are adapted thereto, and then install a plurality of supporting plates 4 on the other side to fix the outer insulation brick 2, and then place another group of outer insulation bricks 2 and inner insulation bricks 3, and so on, so that the inner side of the furnace body 1 can be completely covered to increase the heat insulation performance.
