Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] As shown in Figure 1 and Figure 2 The utility model discloses a prefabricated conical baking-free anchoring brick for high-temperature kiln, which comprises an anchoring brick head, an anchoring brick body and an anchoring brick base which are integrally connected in sequence.
[0023] That is to say, the anchoring brick base, the anchoring brick body and the anchoring brick head are sequentially arranged from bottom to top in the height direction of the anchoring brick. The anchoring brick base, the anchoring brick body and the anchoring brick head can be integrally casted.
[0024] Specifically, the anchoring brick body has opposite first and second connecting surfaces, and the cross-sectional shape of the anchoring brick body is circular. In the direction from the first connecting surface to the second connecting surface, the cross-sectional area of the anchoring brick body gradually increases. In this way, the overall shape of the anchoring brick body is a circular cone with the top removed. The anchoring brick head is connected to the first connecting surface, and the anchoring brick head is a circular cylinder. The outer side surface of the anchoring brick head is provided with a first groove.

[0025] In addition, the anchoring brick base 3 is connected to the second connecting surface, and the anchoring brick base 3 is a cylinder; wherein the outer side surface of the anchoring brick body 2 is provided with a second groove 21. In this way, the second groove 21 can enhance the connection strength between the anchoring brick and other lining materials. In addition, the anchoring corner of the traditional anchoring brick is mostly sharp and right-angled, and the stress concentration degree under high temperature is high, and the design of the anchoring brick body 2 as a conical body can effectively alleviate the stress concentration problem of the whole brick body.
[0026] It should be noted that the anchoring brick head 1 and the anchoring brick base 3 are cylinders, and the design of the anchoring brick body 2 as a conical body greatly increases the contact area with the castable, and the combination with the castable is more compact than the traditional anchoring brick, which is beneficial to the conduction of temperature and energy, reduces energy loss, and easily deals with the scene of sudden change of production temperature, effectively relieves the accumulation and release of thermal stress under high energy, and can make the temperature of the whole insulation layer system of the anchoring brick and the castable more uniform, so that the insulation effect is better. Moreover, the design of the anchoring brick body 2 as a conical body is simple in structure, convenient for vibration and flow of castable, and the castable is filled more uniformly and densely.
[0027] In some embodiments, as shown in Figure 1 and Figure 2 , the second groove 21 is annular, and the second groove 21 extends along the circumferential direction of the anchoring brick body 2.
[0028] It should be noted that the second groove 21 can be arranged at the middle position of the anchoring brick body 2, and in addition, the second groove 21 is coaxially arranged with the whole anchoring brick.
[0029] In some embodiments, as shown in Figure 1 and Figure 2 , the inner diameter of the second groove 21 is 10-20mm. For example, the inner diameter of the second groove 21 is 10mm, 15mm or 20mm. Wherein, the second groove 21 can be semicircular.
[0030] In actual application, the anchoring brick body 2 has a steel reinforcement frame arranged inside. Wherein, the steel reinforcement frame can significantly improve the carrying capacity of the structure, so that it can bear greater load such as weight, pressure, tension and the like. In addition, the steel reinforcement frame provides stable support for the structure to prevent it from deforming or collapsing due to external force.
[0031] In some embodiments, as shown in Figure 1 and Figure 2 , the diameter of the first connecting surface is 140-160mm. For example, the diameter of the first connecting surface is 140mm, 150mm or 160mm.
[0032] It should be noted that the anchor brick brick 1 includes a top, a connecting portion and a bottom connected in sequence from top to bottom, wherein the top and the bottom are both cylindrical, the diameter of the bottom is the same as that of the first connecting surface, the diameter of the top is larger than that of the bottom, the cross-sectional shape of the connecting portion is circular, and the size of the cross-section gradually decreases in the direction from the top surface to the bottom surface of the connecting portion, the size of the top surface is the same as that of the top, and the size of the bottom surface is the same as that of the bottom. In this way, the first groove 11 can be formed between the connecting portion and the bottom.
[0033] In some embodiments, as shown in Figs. 1 and 2, the diameter of the second connecting surface is 300-400 mm. For example, the diameter of the second connecting surface is 300 mm, 350 mm or 400 mm. In this case, the diameter of the anchor brick base 3 is the same as that of the second connecting surface. Figure 1 Figure 2 As shown in Figs. 1 and 2, the diameter of the second connecting surface is 300-400 mm. For example, the diameter of the second connecting surface is 300 mm, 350 mm or 400 mm. In this case, the diameter of the anchor brick base 3 is the same as that of the second connecting surface.
[0034] In optional embodiments, the height of the anchor brick brick 1 is 20-40 mm, the height of the anchor brick brick body 2 is 200-400 mm, and the height of the anchor brick base 3 is 10-20 mm.
[0035] For example, the height of the anchor brick brick 1 is 20 mm, the height of the anchor brick brick body 2 is 360 mm, and the height of the anchor brick base 3 is 20 mm, so that the height of the entire anchor brick is 400 mm.
[0036] In optional embodiments, the anchor brick brick 1, the anchor brick brick body 2 and the anchor brick base 3 are made of the same material, and the material is corundum castable, mullite castable or corundum mullite castable.

[0037] It should be particularly noted that the corundum castable, the mullite castable or the corundum mullite castable are materials provided by the prior art, and the adjustment of the components and the ratio thereof is not involved in the present embodiment.
[0038] Specifically, the corundum castable is prepared by mixing corundum (white corundum, brown corundum, tabular corundum) or alumina as aggregate and powder, adding various superfine powders and calcium aluminate cement as binder, and adjusting the proportion. The aluminum content is usually greater than 85%, and the main crystal phase at high temperature is corundum. The mullite castable is a refractory castable prepared by using mullite as aggregate and powder and adding certain binders. Its main chemical components include alumina and silica, as well as a small amount of additives. Corundum-mullite castable, also known as corundum-mullite wear-resistant castable, is named because its main raw materials, corundum and mullite, have wear-resistant properties. It is made of brown corundum, white corundum, tourmaline, mullite and high-quality alumina, and superfine refractory powder.
[0039] It should be noted that the anchoring brick uses corundum castable, mullite castable or corundum-mullite castable as the main raw material, is preformed, does not need high-temperature firing, saves energy consumption and reduces carbon emissions. In addition, compared with castable forming, it has the advantages of no baking, high quality, convenient installation and replacement.
