Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial kiln lining technology, and in particular to modular multi-layered multiphase ceramic refractory bricks with positioning slots. Background Technology
[0002] Traditional refractory bricklaying in cement rotary kilns is a critical maintenance procedure that is labor-intensive, technically demanding, and time-consuming. Because the laying of refractory bricks in traditional cement rotary kilns relies entirely on the worker's experience, the laying speed is very slow. Furthermore, since the quality of the laying is highly dependent on the worker's experience and skill level, it is difficult to ensure uniform control of brick joints and circumferential tightness, easily leading to weak points. Summary of the Invention
[0003] To address the aforementioned problems, this utility model provides a modular multi-layered multiphase ceramic refractory brick with positioning slots.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A modular multi-layered composite ceramic refractory brick with positioning slots includes a refractory brick body, the bottom surface of which is provided with a cross-shaped positioning tenon, and the top surface of which is provided with a cross groove, the cross groove matching the cross positioning tenon. The refractory brick body includes a working layer, a heat insulation layer, and a structural layer; A lifting ring is pre-embedded in the center of the refractory brick body.
[0005] Preferably, the cross-shaped positioning tenon adopts an asymmetrical structure, and the width of the cross-shaped positioning tenon gradually increases along the length direction of the refractory brick body.
[0006] Preferably, the bottom of the cross groove is designed with a shallow mesh or dot-shaped glue storage tank, and the glue in the storage tank can overflow when the brick is pressed together.
[0007] Preferably, the bottom of the cross groove is designed with a shallow mesh or dot-shaped glue storage tank, and the glue in the storage tank can overflow when the brick is pressed together.
[0008] Preferably, the root of the tenon of the cross-shaped positioning tenon and the edge of the groove of the cross-shaped groove are designed with a small rounded chamfer.
[0009] Preferably, the working layer is disposed on the front side of the refractory brick body, and the working layer is made of high-quality magnesium aluminum spinel or silicon molybdenum material; the back side of the refractory brick body is a heat insulation layer, the heat insulation layer integrates lightweight heat insulation material, and the heat insulation layer achieves "brick-lining integration" through co-pressing or embedded structure; the structural layer is disposed in the middle of the refractory brick.
[0010] Preferably, the lifting ring is made of 304 stainless steel, and the pre-embedded part of the lifting ring is designed with a barbed structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a simple structure, and the refractory bricks connected from top to bottom are positioned accurately through cross-shaped positioning tenons and cross grooves, which greatly speeds up the construction speed of workers.

Detailed Implementation
[0013] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.
[0014] Please refer to the reference. Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model discloses a modular multi-layered composite ceramic refractory brick with positioning slots, comprising a refractory brick body 1. The bottom surface of the refractory brick body 1 is provided with a cross-shaped positioning tenon 8, and the top surface of the refractory brick body 1 is provided with a cross groove 5, which matches the cross positioning tenon 8. The upper and lower connected refractory brick bodies are fixedly connected by the cross groove and the cross positioning tenon. The installer only needs to align the cross groove with the cross positioning tenon to achieve rough positioning of the two connected refractory bricks, which greatly saves the installer's installation time.
[0015] The refractory brick body includes a working layer, a heat insulation layer, and a structural layer; the use of this multi-layered multiphase ceramic refractory brick improves the service life and working strength of the refractory brick.
[0016] A lifting ring is pre-embedded in the center of the refractory brick body. This design, with the lifting ring installed on the refractory brick body, facilitates the use of a crane by installers to lift the refractory bricks through the lifting ring during installation, and enables precise positioning of the refractory bricks during the installation process, resulting in a tighter and more stable installation.
[0017] Preferably, the cross-shaped positioning tenon adopts an asymmetrical structure, and the width of the cross-shaped positioning tenon gradually increases along the length of the refractory brick body. This design facilitates installation by ensuring that the refractory bricks are installed in only one direction, thus preventing incorrect installation orientation.
[0018] Preferably, the bottom of the cross groove is designed with a shallow mesh or dot-shaped adhesive storage tank, which allows the adhesive in the storage tank to overflow when the brick is pressed together. During installation, the installer applies pressure to the lifting ring to ensure that the cross groove and the cross positioning tenon are fully engaged. When the adhesive overflows evenly, it can be determined that the refractory brick is installed in place.
[0019] Preferably, the root of the tenon of the cross-shaped positioning tenon and the edge of the groove of the cross-shaped groove are designed with a small rounded chamfer. This design avoids cracking due to stress concentration caused by machining tolerances during thermal expansion.
[0020] Preferably, the working layer is disposed on the front side of the refractory brick body, and the working layer is made of high-quality magnesium aluminum spinel or silicon molybdenum material; the back side of the refractory brick body is a heat insulation layer, the heat insulation layer integrates lightweight heat insulation material, and the heat insulation layer achieves "brick-lining integration" through co-pressing or embedded structure; the structural layer is disposed in the middle of the refractory brick.
[0021] Preferably, the lifting ring is made of 304 stainless steel, and the embedded part of the lifting ring is designed with a barbed structure. This design makes the lifting ring less likely to fall off.
[0022] As described above, the modular multi-layered multiphase ceramic refractory brick with positioning slot of this utility model simplifies the operation of installers during the installation process and greatly improves the convenience of installation.
[0023] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
