Description

Plug-in type special-shaped magnesia brick Technical Field The utility model relates to the technical field of magnesia bricks, in particular to a plug-in type special-shaped magnesia brick. Background The magnesia brick is produced by high temperature firing, is the most main product in alkaline refractory materials, has the characteristics of high refractoriness, good corrosion resistance to iron oxides, alkaline slag and high-calcium flux, and the like, and is widely applied to metallurgical kilns, and is mainly used for steelmaking alkaline open furnaces, electric furnace bottoms and furnace walls, permanent linings of oxygen converters, nonferrous metal smelting furnaces, high-temperature tunnel kilns, calcined magnesia bricks and cement rotary kiln linings, furnace bottoms and furnace walls of heating furnaces, regenerator checker bricks of glass kilns, and the like. In the current industrial application, the heat storage boiler mainly adopts magnesia bricks as main constituent materials thereof. Because these boilers are exposed to a high temperature environment during operation, conventional cementing materials cannot be used for masonry work. This is because any type of cementitious material loses its adhesive effect at such high temperatures and the tight bond between the materials is not maintained. Therefore, the heat accumulating boiler at the present stage is still constructed in a stacking and forming mode. However, this construction inevitably causes problems during operation of the boiler, such as misalignment and collapse of the components. These problems can lead to serious consequences such as damage to equipment and even safety accidents. These conditions can negatively impact the life of the solid state heat storage boiler, thereby increasing maintenance costs and operational risks. Disclosure of utility model The utility model provides a plug-in type special-shaped magnesia brick, which aims to solve the problems in the background technology. In order to achieve the aim, the utility model provides the technical scheme that the plug-in type special-shaped magnesia brick comprises a first magnesia brick and a second magnesia brick, wherein the first magnesia brick comprises a first brick, and a front bayonet and a rear bayonet are respectively arranged on two sides of the first brick; The second magnesia brick comprises a second brick, wherein front clamping blocks and rear clamping grooves are formed in two sides of the second brick; Hollow grooves are formed in the inner sides of the first brick and the second brick, a reinforcing structure is arranged on the inner side of the hollow groove, the reinforcing structure comprises a reinforcing inner core, an insulating layer is arranged on the outer side of the reinforcing inner core, and a protective layer, a glass wool filling layer and a sound insulation layer are respectively arranged on the inner side of the reinforcing inner core.
