[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-4 This utility model provides a novel refractory brick prefabrication component, including a refractory brick body 1. Edge strips 2 are fixedly connected to the upper and lower ends of one side of the refractory brick body 1. Edge grooves 3 are formed on the upper and lower ends of the side of the refractory brick body 1 away from the edge strips 2. A sliding groove 4 is formed on the inner side of the refractory brick body 1 near the edge strips 2. An outer frame 5 is fixedly connected to the end of the refractory brick body 1 away from the sliding groove 4. A bottom groove 7 is formed at the bottom of the refractory brick body 1. A top plate 8 is fixedly connected to the top of the refractory brick body 1. An inner cavity 6 is formed on the inner side of the refractory brick body 1. The shapes and positions of the edge strips 2 and edge grooves 3 are mutually compatible. The shapes and positions of the sliding grooves 4 and outer frame 5 are mutually compatible. The shapes and positions of the bottom groove 7 and top plate 8 are mutually compatible. A retaining ring 9 is fixedly connected to the bottom end of the refractory brick body 1, located inside the bottom groove 7. An injection groove 10 adapted to the retaining ring 9 is formed on the inner side of the refractory brick body 1 and the top plate 8.

[0020] Slide the outer edge strip 2 of the refractory brick body 1 into the side groove 3 on the other side of the adjacent refractory brick body 1 in sequence, while the outer frame 5 slides into the sliding groove 4, until the refractory brick body 1 forms a ring structure. Then assemble another ring structure and place the ring structure on the other ring structure, so that all the bottom grooves 7 are engaged with the outer side of the corresponding top plate 8, and ensure that the retaining ring 9 is engaged with the inner side of the corresponding injection groove 10. Repeat the operation until the appropriate height is reached.

[0021] The refractory brick body 1 can form a ring through the cooperation of the side groove 3 and the side strip 2. This ring structure design allows multiple refractory brick bodies 1 to be tightly spliced ​​together to form a complete ring structure. Then, by using the cooperation of the bottom groove 7 and the top plate 8, these ring structures can be stacked into cylindrical shapes of different heights. This design allows the prefabricated components to flexibly adjust their height according to actual needs, thereby better adapting to different application scenarios.

[0022] Please see Figures 1-4Several support components are fixedly connected to the inner side of the inner cavity 6. The support components include a support plate 11 fixedly connected to the inner side of the refractory brick body 1. The inner side of the support plate 11 has an inner groove 12. The upper and lower ends of the support plate 11 both have outer grooves 13. The bottom height of the retaining ring 9 is the same as the bottom height of the refractory brick body 1. The top of the retaining ring 9 extends to the inner side of the inner cavity 6. Flow grooves 14 are fixedly connected to both sides of the refractory brick body 1. The flow grooves 14 are fixedly connected to both sides of the inner cavity 6. The two flow grooves 14 are located on the inner side of the sliding grooves 4 and the outer frame 5 on both sides, respectively.

[0023] Refractory castable is injected into all the injection slots 10 at the top, so that the castable enters the inner cavity 6 inside the refractory brick body 1, and then flows to the inner cavity 6 below through the retaining ring 9. The flow slots 14 on both sides ensure the connection of the inner cavity 6 until all the inner cavities 6 are filled. After the castable solidifies, the stacking is completed.

[0024] With the injection groove 10 and retaining ring 9, refractory brick bodies 1 of different heights can be connected. This design allows refractory castable to be injected into the inner cavities 6 of all refractory brick bodies 1 from the uppermost injection groove 10. After the refractory castable has solidified, all refractory brick bodies 1 will be cast into a whole. This integral design significantly improves the stability of the precast component, enabling it to maintain structural integrity in high-temperature environments. Through the cooperation of the chute 4 and the outer frame 5, a seal is formed between adjacent flow grooves 14. This sealing design can effectively prevent leakage of refractory castable during injection, ensuring that the refractory castable can be evenly filled into all inner cavities 6. This not only improves the fluidity and filling efficiency of the refractory castable, but also ensures that the refractory castable can be evenly distributed, thereby enhancing the thermal insulation performance and structural stability of the entire precast component.

[0025] The support plate 11 is designed to support the inner cavity 6 and strengthen the strength of the refractory brick body 1. This design not only improves the mechanical strength of the refractory brick body 1, but also ensures the structural stability of the refractory brick body 1 under high temperature conditions. The distribution of the inner groove 12 and the outer groove 13 can further enhance the structural strength of the inner cavity 6, while providing more filling space for the refractory castable, ensuring that the inner cavity 6 is fully filled.

[0026] The working principle and usage process of this utility model are as follows: The outer edge strip 2 of the refractory brick body 1 is slid into the edge groove 3 on the other side of the adjacent refractory brick body 1 in sequence, while the outer frame 5 is slid into the sliding groove 4 until the refractory brick body 1 forms a ring structure. Then, another ring structure is assembled and placed on the other ring structure, so that all the bottom grooves 7 are engaged with the outer side of the corresponding top plate 8, and the retaining rings 9 are engaged with the inner side of the corresponding injection grooves 10. The operation is repeated until the appropriate height is reached. Refractory castable is injected from all the injection grooves 10 at the top, so that the castable enters the inner cavity 6 inside the refractory brick body 1, and then flows to the inner cavity 6 below through the retaining rings 9. The flow grooves 14 on both sides ensure the connection of the inner cavity 6 until all the inner cavities 6 are filled. After the castable solidifies, the stacking is completed.

[0027] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
