Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, and in particular to a refractory brick. Background Technology

[0002] Refractory bricks are refractory materials made of refractory clay or other refractory raw materials. They have a certain shape and size, can withstand high temperatures, and have good volume stability, thermal shock stability, and slag resistance at high temperatures. They are mainly used for lining industrial kilns and other thermal equipment in metallurgy, glass, cement, ceramics and other industries to protect the equipment body from high temperature corrosion, extend the service life of the equipment and ensure the normal operation of thermal processes.

[0003] Existing refractory bricks improve the fire resistance of buildings by improving the fire resistance of the materials. However, most current refractory bricks are integral fixed structures. Although they are relatively strong and can block fire and heat, they cannot absorb the heat of the fire in actual use, and cannot delay the spread of fire or heat. As a result, they cannot buy more time for fire fighting and rescue. They still have defects in actual use.

[0004] An existing patent (publication number: CN210070595U) discloses a refractory brick structure, relating to the field of refractory brick technology. This refractory brick structure includes a refractory brick with channels on both its front and rear sides, a storage groove in its center, and openings on both sides of the bottom of the storage groove. A mounting groove is symmetrically formed in the center of one side of the refractory brick. This refractory brick structure, through the arrangement of the two channels, allows heat to enter the storage groove through the channels when the refractory brick is subjected to high temperatures, and then the heat is absorbed through the storage groove. The refractory layer further enhances the heat absorption efficiency of the refractory brick, thereby slowing down the spread of heat.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing refractory bricks lack effective positioning structures, resulting in low installation efficiency and difficulty in ensuring installation accuracy. Furthermore, the bricks are prone to damage due to stress concentration during actual use, and their structure is easily severely damaged after being corroded by high-temperature chemicals. Consequently, they are difficult to work stably for a long time under complex working conditions, resulting in a short service life.

[0006] Therefore, a type of refractory brick is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a refractory brick that can solve the problems of existing refractory bricks, which mostly lack an effective positioning structure, resulting in low installation efficiency and difficulty in ensuring installation accuracy. At the same time, the bricks are easily damaged due to stress concentration during actual use, and the bricks are easily severely damaged after being corroded by high temperature and chemical substances, making it difficult to work stably for a long time under complex working conditions and resulting in a short service life.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a refractory brick, comprising a first brick body, a protrusion provided on the front side of the first brick body, a second brick body provided on the front side of the first brick body, the surface of the protrusion being engaged with the inner wall of the second brick body, the first brick body comprising a base layer, a buffer layer provided on the surface of the base layer, a heat insulation layer provided on the surface of the buffer layer, a wear-resistant layer provided on the surface of the heat insulation layer, and an corrosion-resistant layer provided on the surface of the wear-resistant layer.

[0009] Preferably, the base layer is made of alumina, the buffer layer is made of mullite, and the thickness of the buffer layer is 2-4 mm.

[0010] Preferably, the insulation layer is made of diatomaceous earth and has a thickness of 8-12 mm.

[0011] Preferably, the wear-resistant layer is made of cordierite and has a thickness of 5-8mm.

[0012] Preferably, the corrosion-resistant layer is made of zircon and has a thickness of 2-3 mm.

[0014] Preferably, the surface of the first brick is provided with anti-slip texture, and the inner wall of the first brick is provided with groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This application, by setting up a first brick, a protruding block, and a second brick, allows for precise positioning and installation by placing a protruding block on the front side of the first brick, facilitating the first brick to engage with the protruding block on the inner wall of the second brick. This not only improves installation efficiency and accuracy but also enhances the overall stability of the first and second bricks after assembly.

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.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A refractory brick includes a first brick body 1, a protrusion 2 provided on the front side of the first brick body 1, and a second brick body 3 provided on the front side of the first brick body 1. The surface of the protrusion 2 is engaged with the inner wall of the second brick body 3. The first brick body 1 includes a base layer 101, a buffer layer 102 provided on the surface of the base layer 101, a heat insulation layer 103 provided on the surface of the buffer layer 102, a wear-resistant layer 104 provided on the surface of the heat insulation layer 103, and an corrosion-resistant layer 105 provided on the surface of the wear-resistant layer 104.

[0025] In this embodiment: by setting a first brick 1, a protruding block 2, and a second brick 3, the protruding block 2 is set on the front side of the first brick 1 during use, which facilitates the first brick 1 to drive the protruding block 2 to engage with the inner wall of the second brick 3, achieving precise positioning and installation. This not only improves installation efficiency and accuracy but also enhances the overall stability of the first brick 1 and the second brick 3 after splicing. At the same time, the base layer 101 in the first brick 1 provides basic support, the buffer layer 102 can effectively absorb external stress impacts and reduce the risk of damage to the first brick 1, the heat insulation layer 103 can reduce heat transfer and improve the heat insulation performance of the first brick 1, the wear-resistant layer 104 can resist wear during long-term use and extend its service life, and the corrosion-resistant layer 105 can effectively resist chemical corrosion at high temperatures and ensure the structural integrity of the first brick 1. Thus, the first brick 1 can still maintain good working performance under complex working conditions such as high temperature, high stress, and high corrosion, and has excellent comprehensive performance.

[0026] Specifically, such as Figure 3 As shown, the base layer 101 is made of alumina, the buffer layer 102 is made of mullite, and the thickness of the buffer layer 102 is 2-4mm.

[0027] Specifically, such as Figure 3 As shown, the insulation layer 103 is made of diatomaceous earth and has a thickness of 8-12mm.

[0028] Specifically, such as Figure 3 As shown, the wear-resistant layer 104 is made of cordierite, and the thickness of the wear-resistant layer 104 is 5-8mm.

[0029] In this embodiment: the base layer 101 is made of alumina, and its high strength characteristics facilitate stable support; the buffer layer 102 is made of mullite, which helps to improve toughness and effectively disperse stress; the heat insulation layer 103 is made of diatomaceous earth, and its low thermal conductivity helps to block heat conduction; the wear-resistant layer 104 is made of cordierite, which helps to improve the hardness of the first brick 1 and resist frictional wear. When the first brick 1 is subjected to mechanical stress, high temperature environment and wear conditions, the functional layers work together to improve the overall performance and reliability of the first brick 1.

[0030] Specifically, such as Figure 3As shown, the corrosion-resistant layer 105 is made of zircon, and its thickness is 2-3 mm.

[0031] Specifically, such as Figure 3 As shown, the first brick 1 is a cuboid with a length of 230mm, a width of 114mm, and a height of 65mm.

[0032] In this embodiment: the corrosion-resistant layer 105 is made of zircon.

Combined with the standard size of the first brick 1, it not only ensures that the first brick 1 maintains its structural integrity in complex chemical environments, but also facilitates standardized installation in equipment such as industrial kilns, thereby improving construction efficiency and maintenance convenience.

[0033] Specifically, such as Figure 2 As shown, the surface of the first brick 1 is provided with anti-slip texture 4, and the inner wall of the first brick 1 is provided with groove 5.

The inner wall groove 5 can accommodate the deformation caused by expansion, avoiding damage to the first brick 1 due to thermal expansion and contraction, and effectively improving the installation stability and thermal stability of the first brick 1.

[0035] Working principle: During the use of the first brick 1, by setting up the first brick 1, the protruding block 2, and the second brick 3, the protruding block 2 is set on the front side of the first brick 1, which facilitates the first brick 1 to drive the protruding block 2 to engage with the inner wall of the second brick 3, achieving precise positioning and installation. This not only improves installation efficiency and accuracy but also enhances the overall stability of the first brick 1 and the second brick 3 after splicing. At the same time, the base layer 101 in the first brick 1 provides basic support, the buffer layer 102 can effectively absorb external stress impacts and reduce the risk of damage to the first brick 1, the heat insulation layer 103 can reduce heat transfer and improve the heat insulation performance of the first brick 1, and the wear-resistant layer... 104 can resist wear during long-term use and extend service life, while the corrosion-resistant layer 105 can effectively resist chemical corrosion at high temperatures and ensure the structural integrity of the first brick 1. This allows the first brick 1 to maintain good working performance under complex working conditions such as high temperature, high stress, and high corrosion, and has excellent comprehensive performance. The anti-slip texture 4 on the surface of the first brick 1 can increase the friction between the first brick 1 and the second brick 3 and prevent displacement during installation and use. The inner wall groove 5 can accommodate the deformation caused by expansion and avoid damage to the first brick 1 due to thermal expansion and contraction, effectively improving the installation stability and thermal stability of the first brick 1.
