Description

Technical Field

[0001] This utility model relates to the field of tunnel kiln technology, and in particular to a refractory brick structure for the kiln wall of a tunnel kiln with good sealing performance. Background Technology

[0002] A tunnel kiln is a continuous production thermal equipment widely used in the firing of products in industries such as ceramics, refractory materials, and building materials. The performance of the kiln wall structure directly determines the kiln's energy consumption, temperature field stability, and product quality.

[0003] However, in existing equipment, the traditional tunnel kiln walls are mostly constructed using heavy refractory bricks or simple composite bricks of a single material. The brick joints are mostly straight joints, which can easily lead to gas leakage or cold air intake inside the kiln, disrupting the pressure regime and atmosphere stability inside the kiln and increasing energy consumption. Therefore, a tunnel kiln wall refractory brick structure with good sealing performance is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tunnel kiln wall refractory brick structure with good sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel kiln wall refractory brick structure with good sealing performance, comprising two irregular refractory brick bodies, each of which is internally fixedly connected to a first support frame, and each of which is externally located at one end of the irregular refractory brick body, and a connecting groove is provided in the two adjacent connecting grooves.

[0006] The sealing assembly includes a first convex block that is slidably connected in two connecting grooves. The upper surface of the first convex block has multiple second sealing cement grooves. Sealing cement is applied to the second sealing cement grooves and the third sealing cement grooves, and then the first convex block is slid into the two adjacent connecting grooves.

[0007] As a further description of the above technical solution:

[0008] A refractory sealing brick is fixedly connected to the bottom of the first convex block. A third sealing cement groove is opened on one side of the refractory sealing brick. A second support frame is fixedly connected inside the refractory sealing brick. The side of the refractory sealing brick coated with sealing cement is attached to one side of the two irregular refractory brick bodies. When the sealing cement solidifies, the longitudinal brick joint is sealed by the first convex block and the refractory sealing brick to improve the sealing performance.

[0009] As a further description of the above technical solution:

[0010] Each of the irregular refractory brick bodies is fixedly connected to a sealing snap block on one side, and each of the sealing snap blocks has a first sealing cement groove on one side. The horizontal brick joints are sealed by the snap block to further improve the sealing performance.

[0011] As a further description of the above technical solution:

[0012] Each of the irregular refractory brick bodies has a snap-fit ​​groove on its other side. Each snap-fit ​​groove is adapted to a sealing snap-fit ​​block on another irregular refractory brick body. The sealing snap-fit ​​block seals the transverse brick joints, achieving precise interlocking between the bricks and enhancing the stability of the wall.

[0013] As a further description of the above technical solution:

[0014] Each of the shaped refractory brick bodies has a second convex block fixedly connected to one end. Each of the second convex blocks has a fourth sealing cement groove on one side. Sealing cement is applied into the fourth sealing cement groove on the second convex block to strengthen the connection at the end of the brick.

[0015] As a further description of the above technical solution:

[0016] Each of the shaped refractory brick bodies has a concave groove at the other end, and each concave groove is adapted to a second convex block on another shaped refractory brick body, so that the concave groove of the other shaped refractory brick body can slide into the second convex block to form a labyrinth-like sealed channel.

[0017] As a further description of the above technical solution:

[0018] Each of the aforementioned irregular refractory brick bodies has a refractory working layer fixedly connected to one side. Each of the aforementioned refractory working layers is made of high-alumina refractory material, which improves the fire resistance and structural strength.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this tunnel kiln wall refractory brick structure with good sealing performance is achieved by setting up a first convex block, a second sealing cement groove, refractory sealing bricks, a third sealing cement groove, and a second support frame. The sealing cement is applied to the second and third sealing cement grooves, and then the first convex block is slid into two adjacent connecting grooves. At the same time, the side of the refractory sealing brick with sealing cement is attached to one side of the two irregular refractory brick bodies. After the sealing cement solidifies, the longitudinal brick joints are sealed by the first convex block and the refractory sealing bricks, which improves the sealing performance and prevents gas leakage or cold air intake from the kiln, thus avoiding damage to the kiln pressure system and atmosphere stability and increasing energy consumption.

[0021] 2. Compared with the existing technology, the tunnel kiln wall refractory brick structure with good sealing performance is further improved by setting up a snap-fit ​​block, a first sealing cement groove and a snap-fit ​​groove, etc., applying sealing cement in the first sealing cement groove, and then sliding the snap-fit ​​groove on another irregular refractory brick body into the corresponding snap-fit ​​block, thereby sealing the transverse brick joints through the snap-fit ​​block.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 6 The refractory brick structure for the tunnel kiln wall with good sealing performance provided by this utility model includes two irregular refractory brick bodies 1. Each irregular refractory brick body 1 is fixedly connected to a first support frame 2. Each irregular refractory brick body 1 is fixedly connected to a refractory working layer 5 on one side. Each refractory working layer 5 is made of high alumina refractory material. Each irregular refractory brick body 1 has a connecting groove 6 at the far end. Two adjacent connecting grooves 6 are provided with a sealing component 7. Each irregular refractory brick body 1 has a second convex block 8 fixedly connected to one end. Each second convex block 8 has a fourth sealing cement groove 9 on one side. Each irregular refractory brick body 1 has a concave groove 10 at the other end. Each concave groove 10 is adapted to the second convex block 8 on the other irregular refractory brick body 1. Sealing cement is applied to the fourth sealing cement groove 9 on the second convex block 8. Then, the concave groove 10 of the other irregular refractory brick body 1 is slid into the second convex block 8, which is convenient for workers to lay.

[0032] To achieve the purpose of sealing the longitudinal brick joints, the sealing component 7 includes a first convex block 701 slidably connected in two connecting grooves 6. The upper surface of the first convex block 701 is provided with multiple second sealing cement grooves 702. A refractory sealing brick 703 is fixedly connected to the bottom of the first convex block 701. A third sealing cement groove 704 is provided on one side of the refractory sealing brick 703. A second support frame 705 is fixedly connected inside the refractory sealing brick 703. Sealing cement is applied to the second sealing cement grooves 702 and the third sealing cement grooves 704. Then, the first convex block 701 is slid into the two adjacent connecting grooves 6. At the same time, the side of the refractory sealing brick 703 with sealing cement is attached to one side of the two irregular refractory brick bodies 1. After the sealing cement solidifies, the longitudinal brick joints are sealed by the first convex block 701 and the refractory sealing brick 703, improving the sealing performance and preventing gas leakage or cold air intake from the kiln, which would disrupt the kiln pressure regime and atmosphere stability, leading to increased energy consumption.

[0033] To achieve the purpose of sealing the transverse brick joints, a sealing snap block 3 is fixedly connected to one side of each irregular refractory brick body 1. A first sealing cement groove 4 is opened on one side of each sealing snap block 3, and a snap groove 11 is opened on the other side of each irregular refractory brick body 1. Each snap groove 11 is adapted to the sealing snap block 3 on another irregular refractory brick body 1. Sealing cement is applied to the first sealing cement groove 4, and then the snap groove 11 on another irregular refractory brick body 1 is slid into the corresponding sealing snap block 3. The transverse brick joints are sealed by the sealing snap block 3, further improving the sealing performance.

[0034] Working principle: Sealing cement is applied to the fourth sealing cement groove 9 on the second convex block 8. Then, the concave groove 10 of another shaped refractory brick body 1 is slid into the second convex block 8. Sealing cement is then applied to the second sealing cement groove 702 and the third sealing cement groove 704. The first convex block 701 is then slid into the two adjacent connecting grooves 6. Simultaneously, the side of the refractory sealing brick 703 with sealing cement is attached to one side of the two shaped refractory brick bodies 1. After the sealing cement solidifies, the longitudinal brick joints are sealed by the first convex block 701 and the refractory sealing brick 703, improving the sealing performance and preventing gas leakage or cold air intake from the kiln, which could disrupt the kiln's pressure regime and atmosphere stability, leading to increased energy consumption. After laying the first ring, sealing cement is applied to the first sealing cement groove 4. Then, the snap-fit ​​groove 11 on another shaped refractory brick body 1 is slid into the corresponding sealing snap-fit ​​block 3, sealing the transverse brick joints through the sealing snap-fit ​​block 3, further improving the sealing performance.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
