Description

Technical Field

[0001] This utility model relates to the technical field of zirconium corundum bricks, and in particular to a high thermal shock stability AZS brick. Background Technology

[0002] AZS bricks, also known as zirconia-corundum bricks, are manufactured by mixing selected zircon sand and industrial alumina powder in a specific ratio, adding sodium carbonate and boric acid or borax flux, melting the mixture at 1800-1900℃, and then casting it into shape. Zirconia-corundum bricks possess high thermal shock resistance, corrosion resistance, and high refractoriness, making them a core refractory material in high-temperature industries. They are mainly used in glass furnaces, ceramic kilns, metallurgical industries, and petrochemical fields.

[0003] To adapt to different application scenarios, zirconia-corundum bricks are made into various shapes. Common shapes include square bricks, wedge-shaped bricks, cylindrical permeable bricks, honeycomb bricks, gradient conical bricks, and arc-shaped bricks. Among them, arc-shaped zirconia-corundum bricks are refractory bricks specially designed for circular or arc-shaped kiln structures. Through their unique geometric shape, they optimize the distribution of thermal stress, improve the structural sealing and thermal shock resistance, and are widely used in the lining or flue gas passage of high-temperature equipment such as glass kilns, metallurgical furnaces, and rotary kilns.

[0004] However, since the interior of the arc-shaped zirconia-corundum brick is still solid, when the brick wall is too thick, it will cause a certain temperature difference between the inside and outside of the brick wall, which will affect its thermal shock resistance. At the same time, because the structure of the arc-shaped brick is relatively simple, it not only makes the construction more difficult during the stacking, but also the connection between the arc-shaped bricks after the stacking is not strong enough, and the stability is generally not good. Utility Model Content

[0005] The purpose of this invention is to solve the problems of the general high thermal shock resistance and difficult laying of arc-shaped zirconia-corundum bricks in the prior art, and to propose a high thermal shock stability AZS brick.

Positioning components are provided at the openings at both ends of the through groove for positioning and fixing two adjacent bricks vertically. Splicing components are provided at both ends of the brick body for splicing two adjacent bricks horizontally. Centering components are provided on the upper and lower surfaces of the brick body, and sealing components are also provided on the upper and lower surfaces of the brick body for positioning and sealing two adjacent bricks vertically.

[0007] In some embodiments, the inside of the through groove is provided with rounded corners, and there are two through grooves. The angle between the line connecting the center of the two through grooves and the center of the arc-shaped brick is half the central angle of the arc-shaped brick.

[0008] In some embodiments, the positioning component includes a positioning groove and a positioning protrusion. The positioning groove is formed at the lower opening of the through groove, and the positioning protrusion is formed at the upper opening of the through groove and is integrally formed with the brick body.

The second splicing groove is formed on the outer surface of the first splicing protrusion along the height direction, and the second splicing protrusion is disposed in the first splicing groove along the height direction and integrally formed with the brick body. The shape and size of the second splicing groove and the second splicing protrusion are adapted to each other.

[0011] In some embodiments, the centering component includes a limiting protrusion and a centering protrusion disposed on the upper surface of the brick, and a limiting groove and an insertion hole respectively disposed on the lower surface of the brick. There are two limiting protrusions, which are respectively disposed at both ends of the upper surface of the brick. The centering protrusion is disposed on the upper surface of the brick near the side of the second splicing protrusion. The limiting groove is disposed in the middle of the lower surface of the brick, and the insertion hole is adapted to the shape and size of the centering protrusion.

[0013] In some embodiments, several bricks are joined together end to end to form an annular brick layer, the brick layer has a channel inside, and the sealing grooves on the lower surface of several bricks are joined together end to end to form an annular groove, and the sealing protrusions on the upper surface of several bricks are joined together end to end to form an annular protrusion, the shape and size of the annular groove and the annular protrusion are adapted to each other.

[0014] In some embodiments, several of the annular brick layers are stacked from bottom to top to form a cylindrical masonry body, with one brick in the upper brick layer being placed above the joint of two bricks in the lower brick layer.

[0018] 3. This utility model, by placing one brick from the upper layer above the joint of two bricks in the lower layer, utilizes the cooperation of the positioning groove and the positioning protrusion to not only improve the stability of the connection between the two lower bricks, but also ensure the communication between the upper and lower bricks through the grooves. This improves the heat transfer effect within the entire masonry structure, thus preventing excessive temperature differences within the structure and providing a certain degree of thermal shock resistance. Furthermore, the centering component facilitates the placement of the upper brick at the joint of the two lower bricks, aiding in centering and positioning, and ensuring the upper brick is properly laid.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-3 A high thermal shock resistance AZS brick includes an arc-shaped brick body 10, with a through groove 11 extending along its height inside the brick body 10. The inside of the through groove 11 has rounded corners. There are two through grooves 11, and the angle between the line connecting the center of the two through grooves 11 and the center of the arc-shaped brick body 10 is half the central angle of the arc-shaped brick body 10. The uniform distribution of the two through grooves 11 can increase the heat transfer speed in the brick body 10, allowing the heat to be quickly dispersed, thereby preventing excessive temperature differences in different areas inside the brick body 10. This, in turn, disperses thermal stress to a certain extent and improves the thermal shock resistance. Moreover, the corners of the side walls of the through grooves 11 can be rounded. The rounded corner design allows for variations in the through grooves 11, thereby reducing stress concentration and reducing thermal stress, which plays a positive role in improving the thermal shock resistance. Meanwhile, the through groove 11 can effectively save materials during the production of brick 10, which helps to save production costs and also reduces the weight of brick 10, making brick 10 lighter.

[0030] Positioning components are provided at both ends of the through groove 11 for positioning and fixing two adjacent bricks 10. Splicing components are provided at both ends of the brick 10 for splicing two adjacent bricks 10. Sealing components are provided on the upper and lower surfaces of the brick 10 for positioning and sealing between two adjacent bricks 10. The positioning component includes a positioning groove 12 and a positioning protrusion 13. The positioning groove 12 is opened at the lower end of the through groove 11, and the positioning protrusion 13 is opened at the upper end of the through groove 11 and is integrally formed with the brick body 10. The shape and size of the positioning groove 12 and the positioning protrusion 13 are adapted to each other. The splicing assembly includes a first splicing groove 14 and a first splicing protrusion 15. The first splicing groove 14 is formed at one end of the brick body 10 along the height direction, and the first splicing protrusion 15 is integrally formed at the other end of the brick body 10 along the height direction. The shape and size of the first splicing groove 14 and the first splicing protrusion 15 are adapted to each other. The splicing assembly also includes a second splicing groove 16 and a second splicing protrusion 17. The second splicing groove 16 is formed along the height direction on the outer surface of the first splicing protrusion 15, and the second splicing protrusion 17 is disposed along the height direction within the first splicing groove 14 and is integrally formed with the brick body 10. The shape and size of the second splicing groove 16 and the second splicing protrusion 17 are adapted to each other. After the bricklaying is completed, the two adjacent bricks 10 will not only be engaged with the first splicing groove 14 and the first splicing protrusion 15, but the second splicing protrusion 17 in the first splicing groove 14 will also be inserted into the second splicing groove 16 on the first splicing protrusion 15, so that the ends are further engaged, thereby achieving the purpose of double engagement. The engagement not only improves the connection stability between the two adjacent bricks 10, but also ensures that the installation is in place and plays a certain positioning role. Moreover, the engagement achieves mechanical interlocking and disperses thermal stress, reducing the risk of cracking. The upper and lower surfaces of the brick body 10 are provided with centering components. The centering components include a limiting protrusion 24 and a centering protrusion 26 on the upper surface of the brick body 10, and a limiting groove 25 and an insertion hole 27 respectively opened on the lower surface of the brick body 10. There are two limiting protrusions 24, which are respectively located at both ends of the upper surface of the brick body 10. The centering protrusion 26 is located on the side of the upper surface of the brick body 10 near the second splicing protrusion 17. The limiting groove 25 is opened in the middle of the lower surface of the brick body 10, and the shape and size of the insertion hole 27 are adapted to the centering protrusion 26. In order to facilitate the insertion and cooperation between the limiting protrusion 24 and the limiting groove 25 and between the centering protrusion 26 and the insertion hole 27, an angle can be opened on the upper side of the limiting protrusion 24 and the upper end of the centering protrusion 26 for auxiliary insertion.

[0031] The sealing assembly includes a sealing groove 18 and a sealing protrusion 19. The sealing groove 18 is formed on the lower surface of the brick body 10 along the arc length direction of the brick body 10, and the sealing protrusion 19 is integrally formed on the upper surface of the brick body 10 along the arc length direction of the brick body 10. The sealing protrusion 19 is stepped, and the shape and size of the sealing groove 18 and the sealing protrusion 19 are matched. Moreover, after the masonry is completed, the sealing groove 18 on the upper brick 10 will also fit onto the sealing protrusion 19 on the lower brick 10, thereby locking and sealing the connection between the upper and lower bricks 10, further improving the stability of the masonry. At the same time, in conjunction with the splicing components, it can play a good role in positioning the masonry, preventing masonry errors, thus making the masonry work simpler and more convenient, and reducing the difficulty of masonry to a certain extent.

[0032] Reference Figure 4 and 5 Several bricks 10 are joined together end to end to form an annular brick layer 20. The interior of the brick layer 20 has a channel 21. The sealing grooves 18 on the lower surface of several bricks 10 are joined together end to end to form an annular groove 22. The sealing protrusions 19 on the upper surface of several bricks 10 are joined together end to end to form an annular protrusion 23. The shape and size of the annular groove 22 and the annular protrusion 23 are matched. Reference Figure 6 and 7 Several annular brick layers 20 are stacked from bottom to top to form a cylindrical masonry body 30. One brick 10 of the upper brick layer 20 is placed above the joint of two bricks 10 in the lower brick layer 20. This allows the two positioning grooves 12 on the upper brick 10 to fit onto the two adjacent positioning protrusions 13 on the two lower bricks 10. The cooperation between the positioning grooves 12 and the positioning protrusions 13 not only improves the stability of the connection between the two lower bricks 10, but also ensures the communication between the through grooves 11 on the upper and lower bricks 10. This improves the heat transfer effect within the entire masonry body 30, thereby preventing excessive temperature differences within the masonry body 30 and providing a certain degree of thermal shock resistance. Furthermore, the centering component facilitates the placement of the upper brick 10 at the joint of the two lower bricks 10, serving as an auxiliary centering and positioning feature, and making it easier for the upper brick 10 to be stacked in place.

[0033] In this invention, when laying the annular brick layer 20, the first brick 10 is first placed in the required position. Then, the first splicing protrusion 15 at one end of the second brick 10 is inserted into the first splicing groove 14 at one end of the adjacent brick 10 to achieve the purpose of interlocking between the ends of the two adjacent bricks 10. In this process, the second splicing protrusion 17 in the first splicing groove 14 is also inserted into the second splicing groove 16 on the first splicing protrusion 15. Therefore, the ends of the two adjacent bricks 10 will be further interlocked to achieve the purpose of double interlocking. Then, the subsequent bricks 10 are laid in the same way as above. By connecting several bricks 10 end to end, the first brick layer 20 can be built. Then, the next brick layer 20 is laid on top of the aforementioned brick layer 20, using the same splicing method. After the lower brick layer 20 is completed, the two limiting protrusions 24 at the joint ends of two adjacent bricks 10 combine to form a complete protrusion. When laying the upper brick layer 20, the limiting groove 25 on the lower surface of the upper brick layer 20 is fitted onto the complete protrusion. Simultaneously, the insertion hole 27 on the lower surface of the upper brick layer 20 is fitted onto the centering protrusion 26 on the upper surface of the lower brick 10. The time-limiting groove 25 can limit the two limiting protrusions 24, which not only makes the connection between the two adjacent bricks 10 more stable, but also the complete protrusion formed by the lower brick layer 20 and the centering protrusion 26 can play a centering and positioning role in the laying of the upper brick 10, making it easier to accurately lay the upper brick 10 between the two lower bricks 10. Therefore, it can further reduce the difficulty of gradually laying the bricks 10 upwards, and at the same time help to ensure the quality of the masonry construction. Furthermore, during the upward stacking of bricks 10, the sealing groove 18 on the lower surface of the upper brick 10 will also fit onto the annular protrusion 23 on the upper surface of the lower brick layer 20, thereby achieving a sealing and positioning function. Simultaneously, the two positioning grooves 12 on the upper brick 10 fit onto two adjacent positioning protrusions 13 on the lower brick layer 20, further assisting in positioning. Moreover, by having two positioning grooves 12 on one brick 10 fit onto two positioning protrusions 13 on two different bricks 10, the positioning of two adjacent bricks 10 can be controlled. The joints of bricks 0 are restricted to make the joints more secure. Then, the subsequent bricks 10 are laid in the same way as above. By connecting several bricks 10 end to end, the second brick layer 20 can be built. Then, the brickwork can be built upward to form the masonry body 30. Moreover, through the cooperation of the positioning groove 12 and the positioning protrusion 13, the through grooves 11 in each brick layer 20 in the masonry body 30 can be vertically connected, so that the heat in the masonry body 30 can be more easily dissipated, and the temperature in the masonry body 30 can be more uniform.
