Description

Technical Field

[0001] This utility model belongs to the field of tunnel kiln technology, and in particular relates to hollow porous tunnel kiln burner bricks. Background Technology

[0002] Burner bricks are a key component of the combustion system in tunnel kilns. Installed at the connection between the burner and the kiln body, they play a crucial role. They are generally made of special high-temperature and corrosion-resistant materials, possessing excellent thermal stability. Their internal structure is ingeniously designed, with some incorporating pre-embedded screws and other components to enhance stability. Burner bricks must not only withstand the scouring of high-temperature combustion gases but also ensure uniform heat transfer to guarantee a reasonable temperature distribution within the tunnel kiln. High-quality burner bricks improve combustion efficiency, reduce energy consumption, and extend the service life of the tunnel kiln, which is of great significance for ensuring the normal operation of the tunnel kiln and product quality.

[0003] The existing burner bricks have independently installed internal screws, which directly results in the screws not providing any tension to the overall structure of the brick. In actual use, the independent screws are difficult to form a coordinated mechanical support system. When the burner brick is subjected to complex working conditions such as thermal stress and gas erosion, the various parts of the brick are prone to relative displacement and stress concentration. Moreover, the independent screws cannot effectively restrain the expansion and contraction of the brick, making the brick prone to cracks, which in turn affects its service life and performance stability.

[0004] To address these issues, we have developed hollow porous tunnel kiln burner bricks. Utility Model Content

[0005] The purpose of this invention is to provide hollow porous tunnel kiln burner bricks. By setting up a pre-tightening component, the problem that burner bricks in the prior art are prone to cracking when subjected to complex working conditions such as thermal stress and gas erosion is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a hollow porous tunnel kiln burner brick, comprising a brick body, a combustion port and a ventilation port inside the brick body; a pre-tightening assembly is provided inside the brick body, the pre-tightening assembly comprising a pre-embedded rod installed inside the brick body, a tension rod installed on the surface of the pre-embedded rod, a reinforcing rib installed on the surface of the pre-embedded rod, and a screw installed at one end of the pre-embedded rod.

[0008] The present invention is further provided that a protective layer is installed inside the combustion port, and the protective layer is a ceramic coating.

[0009] The present invention is further configured such that the brick body is made of high-alumina refractory material, and zirconium oxide reinforcing material is added inside the brick body.

[0010] The present invention is further configured such that the surface of the tension rod is threaded and arranged circumferentially with the pre-embedded rod as the axis.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model relates to a hollow porous tunnel kiln burner brick, comprising a brick body 1. A combustion port 2 is provided inside the brick body 1. The combustion port 2 is a key component for mixing and burning fuel and air. Its rational design ensures that fuel and air enter the kiln in the optimal mixing ratio, resulting in more complete combustion, improved combustion efficiency, and reduced energy consumption. An air vent 3 is also provided inside the brick body 1; the air vent 3 provides sufficient oxygen for combustion, ensuring the continuous combustion process. The through-hole design allows air to smoothly enter and exit. The pre-tightening assembly 4 is provided inside the brick body 1 to help maintain a stable combustion environment. The pre-tightening assembly 4 includes a pre-embedded rod 401 installed inside the brick body 1, a tension rod 402 installed on the surface of the pre-embedded rod 401, a reinforcing rib 403 installed on the surface of the pre-embedded rod 401, and a screw 404 installed at one end of the pre-embedded rod 401. The pre-embedded rod 401, as the main supporting component of the pre-tightening assembly 4, is pre-embedded inside the brick body 1 and can enhance the overall structural strength of the brick body 1. The screw 404 is used to fix the burner.

[0026] Example 2

[0027] Please see Figures 1-4Based on Example 1, a protective layer 5 is installed inside the combustion port 2. The protective layer 5 is made of ceramic coating. The protective layer 5 is installed inside the combustion port 2 and uses ceramic coating material. Ceramic has good high temperature resistance and corrosion resistance, which can effectively protect the combustion port 2 from the scouring and chemical corrosion of high temperature gas, and extend the service life of the combustion port 2. The brick body 1 is made of high alumina refractory material and has zirconium oxide reinforcing material added inside the brick body 1. The brick body 1 is made of high alumina refractory material, which has high refractoriness and good thermal stability, and can withstand the high temperature environment inside the tunnel kiln. The addition of zirconium oxide reinforcing material can further improve the high temperature strength and corrosion resistance of the brick body 1, so that it can still maintain good performance under harsh working conditions and extend the service life of the brick body 1. The surface of the tension rod 402 is threaded and arranged circumferentially with the embedded rod 401 as the axis. The other end of the embedded rod 401 is equipped with an embedded block 6. The vent 3 is designed to pass through from front to back. A fixed shell 7 is installed on the surface of the brick body 1. The reinforcing rib 403 and the embedded rod 401 are embedded inside the brick body 1.

[0028] The working principle of this utility model is as follows: The pre-embedded rod 401, as the main supporting component of the pre-tightening assembly 4, is pre-embedded inside the brick body 1, which can enhance the overall structural strength of the brick body 1. The surface of the tension rod 402 is threaded and arranged circumferentially with the pre-embedded rod 401 as the axis. This design allows the tension rod 402 to fit tightly with the pre-embedded rod 401. By tightening the screw 404, a pre-tightening force is generated, which tightly pulls all parts of the brick body 1. When the brick body 1 is subjected to complex working conditions such as thermal stress and gas erosion, the tension rod 402 can effectively constrain the expansion and contraction of the brick body 1, prevent the brick body 1 from cracking, and improve the structural stability and service life of the brick body 1.

[0029] The reinforcing rib 403 is installed on the surface of the embedded rod 401, which can further enhance the structural strength of the brick body 1. It can disperse stress, prevent stress concentration, and improve the deformation resistance of the brick body 1. At the same time, the reinforcing rib 403 can also increase the thermal stability of the brick body 1, so that it can maintain good performance in high temperature environment.

[0030] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
