Description
Technical Field
[0001] The utility model relates to the technical field of high-temperature resistant bricks, in particular to high-temperature resistant bricks for cupolas. Background Art
[0002] High-temperature resistant bricks, also known as refractory bricks, are special brick materials that can maintain the stability of their physical and chemical properties in high-temperature environments. They have a very high refractoriness, can withstand high temperatures without softening, deforming or melting, can resist the erosion of high-temperature melts, slag, gases, etc., and have a certain mechanical strength to ensure the stability of the structure in high-temperature environments.
[0003] High-temperature resistant bricks are widely used in the lining construction of kilns, furnaces and other facilities in high-temperature industrial fields such as metallurgy, chemical industry, building materials, and electric power. Generally, refractory mortar is used to fill between high-temperature resistant bricks, but simple mortar bonding is prone to cracking and instability. There are also bricks designed with concave-convex fitting connections, which results in a small connection surface between the connection end and the brick body, making the connection end prone to fracture under external forces. Therefore, how to solve this problem needs to be considered. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problems in the background art and propose a high-temperature resistant brick for cupolas.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] The high-temperature resistant brick for cupolas includes a brick body. A first groove is opened on one side wall of one end of the brick body. The surface where the first groove is located is defined as the back surface of the brick body.

[0017] 1. On the basis of setting the first convex block, the first groove, the second convex block and the second groove, a fixing block and a cavity are added. The fixing block is inserted into the cavity of another brick to connect the two bricks, increasing the contact area at the joint of the two bricks, solving the problem that the connection surface between the connection end and the brick body is not large, resulting in the connection end being broken under external force.

A second groove 4 is formed on the left side wall of the brick body 1, and a second convex block 5 is fixedly connected to the right side wall of the brick body 1. And the inner wall size of the second groove 4 is the same as the outer wall length of the second convex block 5. At the same time, the concave size of the second groove 4 is the same as the protruding length of the second convex block 5.
[0028] A fixing block 6 is fixedly connected to the inner wall of the first bump 3. A cavity 7 is formed inside the brick body 1. The inner wall size of the cavity 7 is the same as the outer wall size of the fixing block 6. The length of the fixing block 6 extending outwards is the same as the depth of the cavity 7 indenting inwards. A heat insulation layer 13 is arranged inside the cavity 7, and the heat insulation layer 13 is fully distributed inside the cavity 7. The heat insulation layer 13 is fixedly connected to the brick body 1. One end of the heat insulation layer 13 close to the fixing block 6 is fixedly connected to the side wall of the fixing block 6.
[0029] A sound insulation mechanism for sound insulation is arranged inside the fixing block 6. The sound insulation mechanism includes three sound insulation boards 14 with different thicknesses. There is a space between the sound insulation boards 14 and the inner walls of the upper and lower sides of the fixing block 6. There is also a certain distance between the sound insulation boards 14. The two sides of the sound insulation boards 14 are fixedly connected to the inner walls of the left and right sides of the fixing block 6. A plurality of support boards 15 for strengthening the structural strength are arranged inside the side walls at the upper and lower ends of the fixing block 6. The support boards 15 divide the inner parts of the upper and lower two plates of the fixing block 6 into a plurality of small spaces, ensuring the structural strength while reducing the self-weight.
[0030] Baffles 8 are fixedly connected to the inner walls at the upper and lower ends of the fixing block 6 at the end far from the brick body 1. One end of the sound insulation board 14 is fixedly connected to the side wall of the baffle 8. Plug-in boards 9 are fixedly connected to the outer side walls at the upper and lower ends of the baffle 8.

The two bricks are combined together by manual pushing. Under the action of external force, the pin plate 9 on the fixing block 6 is inserted into the pin slot 16 of another brick body 1, and the brick bodies 1 in this direction can be combined. Then, align the second groove 4 of another brick body 1 with the second convex block 5 of this brick body 1, and the concave and convex parts of the two brick bodies 1 can be combined manually. By setting the heat insulation layer 13, the heat generated by the operation of the device is prevented from affecting the fixing block 6. The first reinforcing column 10 and the second reinforcing column 11 form a whole inside the brick body 1 to strengthen the whole brick body 1. The third reinforcing column 12 prevents the second convex block 5 from breaking and affecting the connection between the brick bodies 1.
