[0002] Modular refractory precast components are prefabricated functional materials widely used in high-temperature industrial equipment. Their core feature is rapid installation and efficient maintenance through standardized factory production. Used in equipment such as smelting furnaces and rotary kilns, they enhance impermeability and structural strength through a layered injection process of coarse / fine concrete. They play an irreplaceable and vital role in the development of high-temperature industrial production.
[0003] In existing technologies, the temperature changes in the cooling zone and transition zone of large rotary kilns are large and frequent, and they need to withstand strong mechanical forces. The existing brick connection structure is relatively loose, which can easily cause the gaps between bricks to widen, leading to the problem of fire escalation.
[0004] To address this issue, modular fire-resistant prefabricated components and their connection structures are proposed, which possess the advantages of robust structure and fire prevention, thereby solving the problems mentioned in the background technology. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing modular fire-resistant prefabricated components and their connection structures.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular refractory prefabricated component and its connecting structure, including an arc-shaped brick, a joint-filling brick, and an arc-shaped retaining brick. Both ends of the arc-shaped brick are provided with semi-I-shaped grooves, and a joint-filling brick is installed between the semi-I-shaped grooves of two arc-shaped bricks. The joint-filling brick consists of two joint-filling parts and a connecting part between them. Both ends of the connecting part of the joint-filling brick are provided with a second groove. A first groove is provided on the inner side of the semi-I-shaped groove corresponding to the second groove. The semi-I-shaped grooves of the two arc-shaped bricks form an I-shaped cavity, and an arc-shaped retaining brick is installed at the upper and lower ends of the I-shaped cavity. The middle part of the arc-shaped retaining brick extends into the second groove, and the end of the arc-shaped retaining brick extends into the inner side of the first groove of the semi-I-shaped groove.
[0007] As a further description of the above technical solution: the cross-section of the grout brick is an I-shaped structure, and the size of the grout brick is adapted to the size of the I-shaped cavity between the two arc-shaped bricks.
[0008] As a further description of the above technical solution: the arc-shaped brick, the joint-filling brick, and the two arc-shaped retaining bricks constitute a modular refractory prefabricated component, and the connection between the arc-shaped brick, the joint-filling brick, and the two arc-shaped retaining bricks is filled with refractory material adhesive.
[0009] As a further description of the above technical solution: the upper and lower ends of the semi-I-shaped groove are respectively provided with first grooves, and the length of the semi-I-shaped groove corresponds to the length of the arc-shaped brick.
[0010] As a further description of the above technical solution: the two first grooves and the second groove form an arc-shaped groove, and the inner dimension of the arc-shaped groove matches the dimension of the arc-shaped card block.
[0011] As a further description of the above technical solution: the two ends of the connecting part of the grouting brick are respectively provided with a second groove, and the length of the grouting brick matches the length of the arc-shaped brick.
[0012] This utility model has the following beneficial effects: In this invention, a modular refractory prefabricated component is constructed using arc-shaped bricks, joint-filling bricks, and arc-shaped retaining bricks. By connecting the sides of two arc-shaped bricks, the semi-I-shaped grooves on the sides of the two arc-shaped bricks are brought together to form an I-shaped cavity for the installation of the joint-filling bricks. During this process, by placing two arc-shaped retaining bricks at the upper and lower ends of the I-shaped cavity respectively, the two ends of the arc-shaped retaining bricks are embedded in the first groove opened inside the semi-I-shaped groove, while the middle part of the arc-shaped retaining bricks is embedded in the second groove in the middle of the joint-filling bricks. Combined with the refractory adhesive filling the gaps between the arc-shaped bricks, joint-filling bricks, and arc-shaped retaining bricks, a reliable connection between the arc-shaped bricks, joint-filling bricks, and arc-shaped retaining bricks is achieved. This method has the advantages of a reliable connection structure and strong mechanical force resistance, and solves the problems of increased gaps between bricks and fire spread caused by frequent changes in the installation environment temperature of traditional refractory prefabricated components.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, the modular refractory prefabricated component and its connection structure according to the embodiment of this utility model include an arc-shaped brick 1, a joint-filling brick 3, and an arc-shaped retaining brick 4. Both ends of the arc-shaped brick 1 are provided with a semi-I-shaped groove 2, and a joint-filling brick 3 is installed between the semi-I-shaped grooves 2 of the two arc-shaped bricks 1. The joint-filling brick 3 is composed of two joint-filling parts 6 and a connecting part 7 between them. Both ends of the connecting part 7 of the joint-filling brick 3 are provided with a second groove 8. A first groove 5 is provided on the inner side of the semi-I-shaped groove 2 corresponding to the second groove 8. The semi-I-shaped grooves 2 of the two arc-shaped bricks 1 form an I-shaped cavity, and an arc-shaped retaining brick 4 is installed at the upper and lower ends of the I-shaped cavity respectively. The middle part of the arc-shaped retaining brick 4 extends into the second groove 8, and the end of the arc-shaped retaining brick 4 extends into the inner side of the first groove 5 of the semi-I-shaped groove 2. The arc-shaped brick 1, the joint-filling brick 3, and the two arc-shaped retaining bricks 4 are all made of the same refractory material, and the curvature of the arc-shaped retaining brick 4 corresponds to the curvature of the arc-shaped brick 1. In one embodiment, the grouting brick 3 has an I-shaped cross-section, and the size of the grouting brick 3 is adapted to the size of the I-shaped cavity between the two arc-shaped bricks 1. With this structure, it is easy to install the grouting brick 3 between the two arc-shaped bricks 1.
[0018] In one embodiment, the curved brick 1, the joint filler brick 3, and the two curved retaining bricks 4 constitute a modular refractory prefabricated component, and the joints of the curved brick 1, the joint filler brick 3, and the two curved retaining bricks 4 are filled with refractory material adhesive. This structure increases the firmness of the connection between the curved brick 1, the joint filler brick 3, and the two curved retaining bricks 4.
[0019] In one embodiment, the upper and lower ends of the semi-I-shaped groove 2 are respectively provided with first grooves 5, and the length of the semi-I-shaped groove 2 corresponds to the length of the arc-shaped brick 1. With this structure, it is easy to install the arc-shaped brick 1.
[0020] In one embodiment, two first grooves 5 and one second groove 8 form an arc-shaped groove, and the inner dimensions of the arc-shaped groove match the dimensions of the arc-shaped locking brick 4. This structure facilitates the installation of the arc-shaped locking brick 4 and enables it to engage with the arc-shaped brick 1 and the grouting brick 3.
[0021] In one embodiment, the connecting portion 7 of the grouting brick 3 is provided with a second groove 8 at both ends, and the length of the grouting brick 3 matches the length of the arc-shaped brick 1. This structure makes way for the installation of the arc-shaped clip brick 4.
[0022] Working principle: In use, by connecting the sides of two curved bricks 1, the semi-I-shaped grooves 2 on the sides of the two curved bricks 1 are brought together to form an I-shaped cavity for the installation of the joint filler brick 3. During this process, by placing two curved retaining bricks 4 at the upper and lower ends of the I-shaped cavity respectively, the two ends of the curved retaining bricks 4 are embedded in the first groove 5 opened inside the semi-I-shaped groove 2, while the middle part of the curved retaining bricks 4 is embedded in the second groove 8 in the middle of the joint filler brick 3. Combined with the refractory adhesive filling the gaps between the curved bricks 1, joint filler brick 3 and curved retaining bricks 4, a reliable connection between the curved bricks 1, joint filler brick 3 and curved retaining bricks 4 is achieved. When the ambient temperature of the above-mentioned modular refractory prefabricated components changes frequently, the curved bricks 1, joint filler brick 3 and curved retaining bricks 4 are interlocked and locked together. Compared with traditional refractory prefabricated components, they can withstand greater mechanical forces and solve the problems of increased gaps between bricks and fire spread caused by frequent changes in ambient temperature of traditional refractory prefabricated components.
