An opening, an upper burner, and a lower burner are arranged in the brick body. One side of the upper burner is connected to the opening, a connection port is arranged between the upper burner and the lower burner, and the lower burner is in a regular divergent shape. Its beneficial effects are that for this burner brick for a tunnel kiln, through the upper burner and the lower burner, the natural gas sprayed by the natural gas nozzle can be sprayed into the small cavity of the upper burner, and then enter the large cavity of the lower burner through the connection port. Since the space becomes larger, the intensity of the flame is reduced. The material of the brick body is corundum mullite, and corundum mullite has excellent thermal shock resistance and wear resistance, high hardness, corrosion resistance, and high compressive strength, thereby increasing the service life of the device. The whole device has a reasonable structure, is convenient to use, and has strong practicability;

[0027] Refer to Figures 1 - 3As shown in the figure, an embodiment provided by the utility model is a high-strength tunnel kiln burner brick, which includes an installation frame 2 as a connection. One end of the installation frame 2 is detachably connected to the burner brick body 1. A chute 3 is provided on the inner wall of the installation frame 2. Grooves 5 are provided on the left and right sides of the other end of the burner brick body 1 for the installation and connection between the burner brick bodies 1. The shape of the installation frame 2 fits the groove 5. Clamping blocks 7 are slidably connected to the opposite sides of the inner wall of the groove 5. Card slots 4 are provided on the opposite sides of the inner wall of the installation frame 2. The shape of the clamping block 7 fits the card slot 4. Springs 6 are fixedly connected to the opposite ends of the clamping block 7, and the other ends of the springs 6 are respectively fixedly connected to the opposite sides of the inner wall of the groove 5. The installation frame 2, the spring 6 and the clamping block 7 are all made of high-temperature resistant materials. The width of the inner wall of the chute 3 is equal to the width of the clamping block 7. The rear side of the inner wall of the chute 3 and the front end of the clamping block 7 are both arc surfaces.

[0028] Specifically, during installation, first install the installation frame 2 on the left and right sides of the top of the burner brick body 1, then align the installed installation frame 2 with the groove 5 of another burner brick body 1, with the chute 3 facing upwards, and then push the installation frame 2 upwards so that the arc surface of the clamping block 7 contacts the arc surface of the chute 3, causing the clamping block 7 to slide to both sides. After the installation frame 2 is installed in place, the clamping block 7 is snapped into the card slot 4 by the spring 6, and the gap between the burner brick bodies 1 is filled, and the installation can be completed. Secondly, when the burner brick is in use, the installation frame 2, the spring 6 and the clamping block 7 made of high-temperature resistant materials can prevent the connection stability between the burner brick bodies 1 from being affected during use, prevent poor contact between the bricks, resulting in falling off, cracks or peeling, prevent the thermal efficiency of the kiln from being reduced, increase energy consumption, and affect the stability of the temperature in the kiln, thereby improving product quality and reducing production costs.

[0029] Refer to Figure 1 and Figure 2 As shown in the figure, as the protective burner brick body 1, the burner brick body 1 includes a surface layer 8, a barrier layer 9, a strengthening layer 10, an intermediate layer 11 and a flame retardant layer 12. The inner wall of the surface layer 8 is arranged on the outer wall of the strengthening layer 10. The inner wall of the strengthening layer 10 is arranged on the outer wall of the intermediate layer 11. The inner wall of the intermediate layer 11 is arranged on the outer wall of the flame retardant layer 12.

[0030] Specifically, the surface layer 8 can provide the ability to resist high temperature and erosion, protect the internal structure. The barrier layer 9 can prevent heat from transferring to the inside, reducing energy loss. The strengthening layer 10 can provide sufficient mechanical strength and tensile properties to offset the stress caused by temperature changes. The intermediate layer 11 can enhance the barrier effect and further improve the overall heat insulation performance. The flame retardant layer 12 can prevent the flame from penetrating into the internal structure and improve the fire resistance of the structure. Through the multi-layer protected burner block, the high temperature resistance, heat insulation effect, mechanical strength and thermal shock stability of the brick body can be comprehensively improved, the overall use effect and economic benefits can be enhanced, and the protection effect on the tunnel kiln can be increased. A hole is opened in the middle of the burner block body 1, which can not only reduce the weight of the brick body, but also improve the heat insulation performance.

[0031] Working principle: During installation, first install the installation frame 2 on the left and right sides at the top of the burner block body 1. Then align the installed installation frame 2 with the groove 5 of another burner block body 1, with the chute 3 facing the upper side. Then push the installation frame 2 upward so that the arc surface of the latch 7 contacts the arc surface of the chute 3, causing the latch 7 to slide to both sides. After the installation frame 2 is installed in place, the latch 7 is snapped into the card slot 4 by the spring 6, and the gap between the burner block bodies 1 is filled to complete the installation. When the burner block body 1 is in use, the surface layer 8 can provide the ability to resist high temperature and erosion, protect the internal structure. The barrier layer 9 can prevent heat from transferring to the inside, reducing energy loss. The strengthening layer 10 can provide sufficient mechanical strength and tensile properties to offset the stress caused by temperature changes.
