Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, specifically to an air-insulated silica refractory brick. Background Technology

[0002] Silica-based heat-insulating refractory bricks are made primarily of silica (SiO2 content ≥91%). They feature high load softening temperature (≥1560℃) and high-temperature volume stability, and are widely used in the insulation layers of metallurgical and chemical kilns.

[0003] The existing publicly available technology, application number CN202320780724.7, describes a low thermal conductivity corundum refractory brick. It adopts a lightweight reinforcing structure. By opening cavities inside the refractory brick body, the weight of the refractory brick body can be reduced. The air inside the cavity can greatly reduce the thermal conductivity of the refractory brick body, making the thermal conductivity of the refractory brick body even lower. By setting load-bearing ribs and connecting ribs, the weight of the refractory brick body can be reduced while ensuring its overall strength, making the corundum refractory brick more convenient to transport and use.

[0004] Based on the aforementioned patents and existing refractory bricks, it is not difficult to see that the existing refractory bricks have a relatively simple structure, but the stacking process is quite complex and difficult. Moreover, after stacking, the bricks are easily detached by external forces, which affects the stability and firmness of the stack, and the overall performance is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an air-insulated silica refractory brick, which has the advantages of convenient installation, strong stability, and good firmness, thereby solving the problems mentioned in the background technology.

[0007] To achieve the aforementioned advantages of convenient installation, high stability, and good robustness, the specific technical solution adopted by this utility model is as follows:

[0008] An air-insulated silica refractory brick includes a refractory brick body. Baffles and grooves are installed around the top of the refractory brick body, and the size of the baffles and the size of the grooves are the same. Several sets of mating blocks are evenly installed on the surface of both ends of the refractory brick. A mating groove is opened on one side of the mating block on the surface of the refractory brick body.

[0009] Furthermore, the height of the docking block gradually increases.

[0010] Furthermore, the depth of the docking groove gradually increases.

[0011] Furthermore, a heat insulation cavity is provided inside the refractory brick body.

[0012] Furthermore, the interior of the heat insulation cavity is provided with several sets of air slots.

[0013] Furthermore, both the baffle and the connecting block are integrally formed with the refractory brick.

[0014] Compared with the prior art, this utility model provides an air-insulated silica refractory brick, which has the following beneficial effects:

[0015] This utility model employs baffles, baffle grooves, connecting blocks, and connecting slots. In actual use, by aligning the baffles on the surface of the refractory bricks with the connecting slots and inserting them, the splicing operation of two sets of refractory bricks can be achieved. Since the baffles and connecting slots on the surface of the refractory bricks are staggered, when the refractory bricks are pushed to one side, they can be blocked by the connecting slots or baffles on the other side, thus preventing the refractory bricks from moving further and preventing them from detaching, ensuring the stability of the stacking. At the same time, the corresponding insertion of multiple sets of connecting slots and connecting blocks of different lengths can also provide secondary fixing and limiting of the refractory bricks, further ensuring the stability and firmness of the stacking, facilitating better stacking and use. The device as a whole has the advantages of convenient installation, strong stability, and good firmness. Attached Figure Description

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, an air-insulated silica refractory brick is provided.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, an air-insulated silica refractory brick according to an embodiment of the present utility model includes a refractory brick body 1. Baffles 4 and baffle grooves 7 are installed on the top four sides of the refractory brick body 1, and the size of the baffles 4 and the size of the baffle grooves 7 are the same. Several sets of mating blocks 5 are evenly installed on the surface of both ends of the refractory brick. A mating groove 6 is opened on one side of the mating block 5 on the surface of the refractory brick body 1.

[0025] In one embodiment, the height of the mating block 5 gradually increases. The height of the mating block 5 is set to achieve a stepped connection operation by increasing the height, thereby improving the overall connection stability and strength.

[0026] In one embodiment, the depth of the mating groove 6 gradually increases, and the depth of the mating groove 6 is set to be used in conjunction with the mating block 5.

[0027] In one embodiment, a heat insulation cavity 2 is provided inside the refractory brick body 1. The heat insulation cavity 2 is provided to facilitate the opening of the air duct 3.

[0028] In one embodiment, the heat insulation cavity 2 is provided with several sets of air grooves 3. The air grooves 3 are set to form an air gap, which is equivalent to dividing the brick into two parts in a disguised way, in order to block (as much as possible) the heat conduction of the brick itself, and play a role in heat insulation.

[0029] In one embodiment, the baffle 4 and the connecting block 5 are integrally formed with the refractory brick. The integral forming setting is to ensure the integrity and flatness of the structure, avoid the complexity and tediousness of secondary processing in the later stage, and reduce the difficulty of brick production.

[0030] Working principle: In actual use, the splicing operation of two sets of refractory bricks can be achieved by aligning the baffle 4 on the surface of the refractory brick body 1 with the baffle groove 7 and inserting them. At this time, since the baffle 4 and the baffle groove 7 on the surface of the refractory brick are staggered, when the refractory brick is pushed to one side, it can be blocked by the baffle groove 7 or baffle 4 on the other side, thereby preventing the refractory brick from moving further and preventing the refractory brick from falling off, ensuring the stability of the stacking. At the same time, the corresponding insertion of multiple sets of docking grooves 6 of different lengths and docking blocks 5 can also fix and limit the refractory bricks for a second time, further ensuring the stability and firmness of the stacking, making it easier to stack and use. Then, air can be stored through the internal air groove 3. Since air is a poor conductor of heat, it can improve the overall heat insulation effect and make it easier to use. The device as a whole has the advantages of convenient installation, strong stability and good firmness.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
