It is usually made of ceramic fiber and other refractory materials. However, ceramic fiber sheets are usually bundled into blocks by binding straps and then inserted into fixing rods connected and fixed to the inner wall of the furnace body for fixation. This method of fixing the square blocks composed of ceramic fiber sheets has a single structure and is prone to loosening and falling off, resulting in a reduction in the heat insulation efficiency of the furnace body. If not discovered in time, it will also burn out the furnace body. Summary of the Utility Model

[0025] When bundling the ceramic fiber sheets 2 with the binding belt 1, the sleeve 8 is clamped inside the ceramic fiber sheets 2. When the binding belt 1 bundles the ceramic fiber sheets 2, the ceramic fiber sheets 2 are squeezed and clamped to fix the sleeve 8. After fixing the ceramic fiber sheets 2 fixed by the binding belt 1, the sleeve 8 is aligned with the fixing rod 6 at the front end of the steel plate 4, and the sleeve rod is inserted and sleeved on the outer wall of the fixing rod 6. While sleeving the sleeve 8, the clamping blocks 7 on the outer wall of the fixing rod 6 slide in the chutes 11 on the inner wall of the sleeve 8. When the sleeve 8 is completely sleeved on the outer wall of the fixing rod 6, just the clamping blocks 7 on the outer wall of the fixing rod 6 will catch the protrusions 12 on the surface of the chutes 11 on the inner wall of the sleeve 8 to fix the sleeve 8. The clamping blocks 7 clamp and fix the protrusions 12 to prevent the sleeve 8 from falling off and fix the ceramic fiber sheets 2 fixed by the binding belt 1

[0026] As Figure 4 and Figure 5As shown, fixing plates 9 are provided at the upper and lower ends of the sleeve 8. Barbs 10 are densely distributed on the surfaces of the two fixing plates 9. The barbs 10 are used to increase the friction between the fixing plates 9 and the ceramic fiber sheet 2. The sleeve 8 and the fixing plates 9 are fixedly connected by welding. Both the sleeve 8 and the fixing plates 9 are made of iron material.

[0027] When the fixing piece 14 is clamped and fixed on the outer wall of the ceramic fiber sheet 2, the barbs 10 can better fix the fixing piece 14 and prevent the fixing piece 14 from falling off between the ceramic fiber sheets 2. The sleeve 8 and the fixing plates 9 made of iron have better high-temperature resistance.

[0028] As Figure 2 and Figure 3 As shown, a fixing piece 14 is provided at the rear end of the fixing rod 6. Screws 13 are provided on both the upper and lower sides of the front end of the fixing piece 14. The fixing rod 6 is fixedly connected to the steel plate 4 through the screws 13 at the front end of the fixing piece 14. A ceramic fiber blanket 3 is provided between the steel plate 4 and the ceramic fiber sheet 2. A plurality of through holes 15 are equidistantly opened at the front end of the ceramic fiber blanket 3. The ceramic fiber blanket 3 can be sleeved on the outer wall of the fixing rod 6 through the through holes 15.

[0029] After fixing the fixing rod 6 to the front end of the steel plate 4 through the screws 13, the ceramic fiber blanket 3 is sleeved on the outer wall of the fixing rod 6 through the through holes 15, so that the ceramic fiber blanket 3 is fitted and fixed on the front end surface of the steel plate 4.

[0030] As Figure 1 and Figure 2 As shown, a ceramic fiber compensation blanket 5 is provided between the upper and lower ends of a plurality of ceramic fiber sheets 2. The ceramic fiber compensation blanket 5 is used to support the stacked ceramic fiber sheets 2. Filling adhesives 16 are coated on both the upper and lower ends of the ceramic fiber compensation blanket 5.

[0031] When stacking the ceramic fiber sheets 2, after horizontally placing the ceramic fiber sheets 2, the ceramic fiber compensation blanket 5 coated with the filling adhesive 16 is laid on the upper end of the ceramic fiber sheets 2, and then the ceramic fiber sheets 2 are laid, and so on for stacking and installation.

[0032] Working principle of the utility model: When bundling the ceramic fiber sheet 2 with the bundling belt 1, the sleeve 8 is clamped inside the ceramic fiber sheet 2. When the bundling belt 1 bundles the ceramic fiber sheet 2, the ceramic fiber sheet 2 is squeezed, and the fixing piece 14 on the outer wall of the sleeve 8 clamps and fixes the sleeve 8. Moreover, the barbs 10 on the outer wall of the fixing piece 14 can better fix the fixing piece 14 to prevent the fixing piece 14 from falling off between the ceramic fiber sheets 2. After fixing the ceramic fiber sheet 2 fixed by the bundling belt 1, align the sleeve 8 with the fixing rod 6 at the front end of the steel plate 4, and insert and sleeve the sleeve rod on the outer wall of the fixing rod 6. While sleeving the sleeve 8, the clamping block 7 on the outer wall of the fixing rod 6 slides in the chute 11 on the inner wall of the sleeve 8. When the sleeve 8 is completely sleeved on the outer wall of the fixing rod 6, exactly the clamping block 7 on the outer wall of the fixing rod 6 will catch the convex block 12 on the surface of the chute 11 on the inner wall of the sleeve 8 to fix the sleeve 8. The clamping block 7 clamps and fixes the convex block 12 to prevent the sleeve 8 from falling off and fixes the ceramic fiber sheet 2 fixed by the bundling belt 1. After installing a row of ceramic fiber sheets 2, lay the ceramic fiber compensation blanket 5 coated with the filling glue 16 on the upper end of the ceramic fiber sheet 2, and then lay the ceramic fiber sheet 2, and so on for stacking and installation.
