Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, specifically a composite brick for kilns. Background Technology

[0002] Furnaces are widely used in metallurgy, building materials, chemical industry and other fields. They are key equipment for realizing high-temperature processes. There are many forms of kiln roof structure. Suspended ceiling is one of the forms of the furnace roof. In the installation process, composite bricks are required to build the furnace roof. For example, the Chinese utility model patent with announcement number CN203310252U and titled "Refractory Brick Assembly" includes a ceiling brick body. A hanging brick rod is inserted into the hanging groove of the ceiling brick body. The hanging brick rod is connected to the ceiling brick body by a brick pin. The hanging brick rod has a hanging hole. The ceiling brick body has a regular hexahedral structure, and the hanging brick rod has a square prism structure. The hanging groove on the ceiling brick body matches the hanging brick rod. The hanging hole is located at the upper part of the hanging brick rod, and a brick rod insertion hole is located at the lower part of the hanging brick rod. The brick pin passes through the brick insertion hole of the ceiling brick body and the brick rod insertion hole on the hanging brick rod to fix the hanging brick rod to the ceiling brick body. This ceiling brick assembly has the advantages of good integrity, long service life, and low manufacturing cost, and is widely applicable to tunnel kilns of various structural forms. Most of the existing technologies mentioned above improve the overall structure. However, in the process of installing existing composite bricks, the ceiling bricks and the hanging brick rods adopt an interlocking structure. However, two adjacent refractory bricks are only in a mating state. During the operation of the kiln, heat will be lost through the gaps, resulting in heat leakage and reducing the heat insulation performance of the kiln roof. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please refer to Figure 1 - Figure 9This utility model provides the following technical solution: a combination brick for kilns, comprising a first combination brick 1, a second combination brick 2, and a connecting block 3 disposed between the two. A T-shaped rod 16 is nested inside the connecting block 3. The opposite sides of the first combination brick 1 and the second combination brick 2 are laterally connected by a connecting post 1 8 and a connecting hole 1 9, and a connecting post 2 10 and a connecting hole 2 11, which can be interlocked. The outer side of the first combination brick 1 is provided with a fixing post 12 and a fixing hole 13, and the outer side of the second combination brick 2 is provided with a fixing post 2 14 and a fixing hole 2 15, for alignment and splicing with adjacent combination bricks. A modular assembly method is adopted to reduce the gap between the first combination brick 1 and the second combination brick 2. During installation, the connecting post 1 8 is aligned with the connecting hole 1 9, and the connecting post 2 10 is aligned with the connecting hole 2. 11. This allows connecting column 18 and connecting column 210 to fully enter the interior of connecting hole 19 and connecting hole 21, enabling the horizontal insertion of combined brick 11 and combined brick 22. This achieves a tight installation between combined brick 11 and combined brick 22, reducing gaps between bricks and preventing heat leakage. Simultaneously, for adjacent combined brick 11 and combined brick 22, fixing column 12 is aligned with fixing hole 13 and fixing column 24 is aligned with fixing hole 25, allowing fixing column 12 and fixing column 24 to fully enter fixing hole 13 and fixing hole 25, thus realizing the installation of adjacent combined brick 11 and combined brick 22. The design of the fixing columns and fixing holes allows multiple combined bricks to be extended and spliced ​​laterally, forming a continuous and closed kiln roof structure, improving the overall heat insulation performance and structural stability.

[0016] The upper end face of the composite brick 1 is provided with a first insertion post 4, the upper end face of the composite brick 2 is provided with a second insertion post 6, and the lower end face of the connecting block 3 is provided with a first insertion hole 5 for inserting the first insertion post 4 and a second insertion hole 7 for inserting the second insertion post 6. During the installation process, the first insertion hole 5 and the second insertion hole 7 are aligned with the first insertion post 4 and the second insertion post 6 to achieve a longitudinal connection between the composite brick 1, the composite brick 2 and the connecting block 3, which enhances the overall structure's anti-sagging and anti-displacement capabilities, is suitable for the load-bearing requirements of the ceiling structure, and is also convenient for modular installation and disassembly. The connecting block 3 of combined brick 1 and combined brick 2 is a sliding connection, while the plug-in post 1, plug-in hole 1, plug-in post 2, and plug-in hole 2 are plug-in connections. Sliding grooves are opened in opposite directions of combined brick 1 and combined brick 2, and a sliding block is fixed on the outside of the connecting block 3 so that the sliding block is aligned with the sliding groove to complete the installation of the connecting block 3 of combined brick 1 and combined brick 2. The sliding connection facilitates fine adjustment and alignment during installation, while the plug-in connection ensures that it is not easy to loosen after connection. The combination of the two ensures both construction flexibility and the stability and sealing of the final structure.

[0017] Example 2: Based on Example 1, a connection structure is also disclosed, the specific structure of which is as follows: Figure 3 - Figure 9 As shown: A top cover 21 is inserted into the upper end of the T-shaped rod 16. A fixing bracket 22 is fitted on the outer side of the T-shaped rod 16. A top column 23 is connected through the T-shaped rod 16 and the top cover 21. The top column 23 is placed between the T-shaped rod 16 and the top cover 21. Since a rectangular groove is opened on the upper end face of the T-shaped rod 16, the connecting block 3 at the bottom end of the top cover 21 is inserted into the rectangular groove to realize the installation of the top cover 21 and the T-shaped rod 16. The T-shaped rod 16 is initially fixed on the outside of the top column 23. The fixed frame 22 has a fixed block inside, and the fixed block extends through the T-shaped rod 16 to the connecting block 3 at the bottom of the top cover 21, realizing the connection between the fixed frame 22 and the top cover 21. The fixed frame 22 is aligned with the square hole opened on the outside of the T-shaped rod 16, so that the fixed block inside the fixed frame 22 extends through the T-shaped rod 16 to the connecting block 3 at the bottom of the top cover 21, realizing the tenon and mortise connection. At the same time, during the installation process, the upper and lower ends of the inner side of the fixed frame 22 are provided with cylinders and round holes to complete the insertion connection of the two sides of the fixed frame 22, realizing the installation of the fixed frame 22. The top column 23 further locks the top cover 21 and the T-shaped rod 16 to prevent them from falling off. The through structure of the fixed block makes the fixed frame 22, the T-shaped rod 16 and the top cover 21 form an integral connection, which significantly enhances the overall rigidity and vibration resistance, and is suitable for high temperature and high pressure kiln environment.

[0018] On the opposite sides of combined brick 1 and combined brick 2, there are through holes 17 and 18. T-shaped rod 16, through holes 17 and 18 are nested together. T-shaped rod 16 is placed between combined brick 1 and combined brick 2. During the insertion connection of combined brick 1 and combined brick 2, T-shaped rod 16 is placed between through holes 17 and 18. At the same time, limit posts are fixed inside through holes 17 and 18. Limit holes are opened on the outside of T-shaped rod 16. The limit holes are aligned with the limit posts for installation. The installation of combined brick 1, combined brick 2 and T-shaped rod 16 is completed. Then, connecting block 3 is nested on the outside of T-shaped rod 16 to reduce the movement of T-shaped rod 16. T-shaped rod 16 passes through the through holes to further lock the two combined bricks and prevent them from shifting when subjected to lateral force. It is especially suitable for reinforcing the area with large force in the middle of the kiln top and improving the shear resistance of the overall structure. Mounting holes 19 and 20 are respectively opened on the opposite outer surfaces of combined brick 1 and combined brick 2. T-shaped rod 16, mounting holes 19 and 20 are nested together. T-shaped rod 16 is placed between adjacent combined brick 1 and combined brick 2. During installation, T-shaped rod 16 is inserted into the interior of mounting holes 19 and 20. Since there are also limit posts fixed inside mounting holes 19 and 20, the limit holes on the outer side of T-shaped rod 16 are aligned with the limit posts for installation. This completes the installation of combined brick 1, combined brick 2 and T-shaped rod 16. The mounting holes provide additional fixing points for T-shaped rod 16. Different fixing methods can be selected according to the needs of the kiln roof structure, which enhances the applicability and installation flexibility of the combined bricks, especially suitable for the assembly of non-standard or irregular kiln roofs.
