Description

Technical Field

[0001] This utility model relates to the field of magnesium brick technology, specifically to a plug-in irregular-shaped magnesium brick. Background Technology

[0002] Magnesia bricks are made by high-temperature firing and are the most important product among alkaline refractory materials. They are characterized by high refractoriness and good resistance to iron oxides, alkaline slags and high-calcium fluxes. They are widely used in metallurgical kilns. Magnesia bricks are mainly used in the bottom and walls of steelmaking alkaline open-hearth furnaces and electric furnaces, permanent linings of oxygen converters, non-ferrous metal smelting furnaces, high-temperature tunnel kilns, calcined magnesia bricks and cement rotary kiln linings, bottom and walls of heating furnaces, and checker bricks in glass kiln regenerators, etc.

[0003] In current industrial applications, thermal storage boilers primarily use magnesia bricks as their main structural material. Because these boilers operate in a high-temperature environment, traditional cementitious materials cannot be used for their construction. This is because any type of cementitious material loses its bonding effectiveness at such high temperatures, failing to maintain a tight bond between the materials.

[0004] Therefore, current thermal storage boilers are still constructed using a stacking method. However, this construction method inevitably leads to problems during boiler operation, such as component misalignment and collapse. These problems can result in serious consequences, such as equipment damage or even safety accidents. All of these situations negatively impact the service life of solid thermal storage boilers, thereby increasing maintenance costs and operational risks. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-5 This utility model discloses a plug-in irregular magnesia brick, including a first magnesia brick 1 and a second magnesia brick 2. The first magnesia brick 1 includes a first brick 101, and a front latch 102 and a rear latch 103 are respectively opened on both sides of the first brick 101.

[0025] The second magnesia brick 2 includes a second brick 201, and the second brick 201 has a front locking block 202 on both sides and a rear locking slot 203.

[0026] By setting up No. 1 magnesia bricks and No. 2 magnesia bricks, two different types of magnesia bricks can be connected in different ways, enabling quick and accurate interlocking between the magnesia bricks. This simplifies the magnesia brick masonry process, improves construction efficiency, enhances the connection strength and stability between magnesia bricks, prevents component displacement and collapse, effectively extends the service life of the thermal storage boiler, reduces maintenance costs and operational risks, and avoids the gap problems that may occur in traditional masonry methods, reducing heat loss and improving the thermal efficiency of the thermal storage boiler.

[0027] Hollow grooves 3 are provided on the inner side of the first brick 101 and the second brick 201. A reinforcing structure 4 is provided on the inner side of the hollow groove 3. The reinforcing structure 4 includes a reinforced inner core 401. An insulation layer 402 is provided on the outer side of the reinforced inner core 401. A protective layer 404, a glass wool filling layer 405, and a sound insulation layer 406 are respectively provided on the inner side of the reinforced inner core 401.

[0028] The reinforced inner core 401 is made of high-strength, high-temperature-resistant materials, such as high-alumina or silica materials. These materials not only have excellent high-temperature resistance but also high strength and hardness, and can maintain stable mechanical properties in high-temperature environments, providing reliable support and protection for the magnesia bricks.

[0029] The insulation layer 402 and glass wool filling layer 405 set in the reinforced inner core 401 give the magnesia brick good high temperature resistance and can maintain a stable connection in high temperature environment. This avoids the problem of component loosening caused by the failure of traditional adhesive materials due to high temperature. In addition, the reinforcing ribs 403 and protective layer 404 further enhance the connection strength and stability of the magnesia brick, improve the thermal shock resistance of the magnesia brick, and enable it to maintain stable performance in harsher working environments.

[0030] Specifically, the openings of the front latch 102 and the rear latch 103 between two adjacent first bricks 101 are opposite each other, and a splicing block 104 is movably engaged between the front latch 102 and the rear latch 103.

[0031] In this implementation scheme, the splicing block 104 not only enhances the connection stability between adjacent No. 1 magnesia bricks 1, but also further simplifies the splicing process of magnesia bricks, making splicing more convenient and efficient. Through the snap-fit ​​action of the splicing block 104, the loosening or detachment of the No. 1 magnesia brick 1 during use can be effectively prevented, thus improving the overall structural stability.

[0032] Specifically, two adjacent second bricks 201 are movably connected by a front locking block 202 and a rear locking slot 203.

[0033] In this embodiment, the cooperative design of the front locking block 202 and the rear locking groove 203 makes the connection between the second magnesia bricks 2 tighter and more stable. The shape of the front locking block 202 matches the shape of the rear locking groove 203. When two adjacent second bricks 201 are spliced, the front locking block 202 can smoothly lock into the rear locking groove 203, forming a strong connection structure. This locking method not only simplifies the magnesia brick laying process but also improves construction efficiency, while ensuring the connection strength and stability between the magnesia bricks.

[0034] Specifically, the thermal insulation layer 402 is a polystyrene particle mortar curing layer, the protective layer 404 is a polystyrene foam layer, and the sound insulation layer 406 is a glass fiber layer.

[0035] In this embodiment, the polystyrene particle mortar curing layer used in insulation layer 402 has good thermal insulation performance, which can effectively reduce heat transfer and improve the insulation effect of magnesia bricks. At the same time, the polystyrene particle mortar curing layer also has high strength and durability, and can maintain stable performance in high-temperature environments, providing reliable thermal insulation protection for magnesia bricks.

[0036] The polystyrene foam layer used in the 404 protective layer has excellent lightweight, heat insulation, waterproof, and moisture-proof properties. It effectively prevents the intrusion of moisture and humidity, protecting the internal structure of the magnesia bricks from damage. Simultaneously, the polystyrene foam layer also possesses certain seismic resistance, mitigating the impact of external shocks on the magnesia bricks to some extent and improving their seismic resistance.

[0037] The glass fiber layer used in the sound insulation layer 406 has excellent sound insulation performance, effectively blocking the transmission of noise and improving the sound insulation effect of magnesia bricks. In addition, the glass fiber layer also has high strength and stability, maintaining stable performance in high-temperature environments, providing reliable sound insulation protection for magnesia bricks.

[0038] Specifically, a reinforcing rib 403 extends through the inner side of the reinforced inner core 401, and the reinforcing rib 403 is located between the protective layer 404, the glass wool filling layer 405, and the sound insulation layer 406.

[0039] In this embodiment, the addition of reinforcing ribs 403 further enhances the structural strength of the reinforced core 401, enabling it to withstand greater pressure and tension, and improving the overall load-bearing capacity and stability of the magnesia brick. The reinforcing ribs 403 are made of a similar high-temperature resistant material to the reinforced core 401, ensuring that they maintain their mechanical properties even under high-temperature conditions, providing durable and stable support for the magnesia brick. Through the reinforcing effect of the reinforcing ribs 403, the magnesia brick can better resist thermal stress under high-temperature conditions, reducing deformation and cracking caused by temperature changes, and extending the service life of the magnesia brick.

[0040] Specifically, the inner side of the reinforced inner core 401 is provided with a vent hole, which is located between the protective layer 404, the glass wool filling layer 405 and the sound insulation layer 406.

[0041] In this embodiment, the vent holes effectively improve the ventilation conditions inside the magnesia bricks, enabling the magnesia bricks to dissipate heat better in high-temperature environments and avoiding performance degradation caused by heat accumulation.

[0042] During use, workers can choose to splice either No. 1 magnesia brick 1 or No. 2 magnesia brick 2 according to actual construction needs. First, align the front locking slot 102 on the first brick 101 of No. 1 magnesia brick 1 with the rear locking slot 103 on the first brick 101 of the adjacent No. 1 magnesia brick 1, and then snap the splicing block 104 between the front locking slot 102 and the rear locking slot 103 to achieve a quick connection between the No. 1 magnesia bricks 1.

[0043] Similarly, for the second magnesia brick 2, the front locking block 202 on the second brick 201 is inserted into the rear locking groove 203 on the second brick 201 of the adjacent second magnesia brick 2 to complete the connection between the second magnesia bricks 2.

[0044] During the connection process, the tight fit between the front locking block 202 and the rear locking slot 203, along with the snap-fit ​​action of the splicing block 104, makes the connection between the magnesia bricks more stable and less prone to loosening or falling off. At the same time, this plug-in connection method greatly simplifies the magnesia brick laying process and improves construction efficiency.

[0045] Furthermore, the performance of the magnesia bricks is further enhanced by incorporating the reinforcing structure 4. The reinforced inner core 401, made of high-strength, high-temperature-resistant materials, provides reliable support and protection for the magnesia bricks. The insulation layer 402 and the glass wool filling layer 405 give the magnesia bricks excellent high-temperature resistance, enabling them to maintain a stable connection in high-temperature environments. The protective layer 404 and the sound insulation layer 406 respectively improve the waterproof, moisture-proof, and sound insulation properties of the magnesia bricks. The addition of the reinforcing ribs 403 further strengthens the structural strength of the reinforced inner core 401, improving the overall load-bearing capacity and stability of the magnesia bricks.

[0046] Finally, the vents effectively improve ventilation inside the magnesia bricks, allowing them to dissipate heat better in high-temperature environments and preventing performance degradation due to heat buildup. This design not only enhances the durability and service life of the magnesia bricks but also enables them to maintain stable performance even in harsher working environments.

[0047] In summary, this plug-in shaped magnesia brick, by setting up Magnesia Brick No. 1 and Magnesia Brick No. 2, utilizes two different types of magnesia bricks to make different connections, enabling the magnesia bricks to be quickly and accurately plugged in, simplifying the magnesia brick masonry process, improving construction efficiency, increasing the connection strength and stability between magnesia bricks, avoiding component displacement and collapse, effectively extending the service life of the thermal storage boiler, reducing maintenance costs and operational risks, and avoiding the gap problems that may occur in traditional masonry methods, reducing heat loss and improving the thermal efficiency of the thermal storage boiler.

[0048] By setting up the reinforced structure 4, the insulation layer 402 and glass wool filling layer 405 set in the reinforced inner core 401 enable the magnesia brick to have good high temperature resistance and maintain a stable connection state in high temperature environments. This avoids the problem of component loosening caused by the failure of traditional adhesive materials due to high temperature. In addition, the reinforcing ribs 403 and protective layer 404 further enhance the connection strength and stability of the magnesia brick, improve the thermal shock resistance of the magnesia brick, and enable it to maintain stable performance in harsher working environments.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
