Description

Technical Field

[0001] The present application relates to the field of refractory composite clay bricks, and in particular to a refractory composite clay brick structure for a heating furnace. Background Art

[0002] A heating furnace is a device used to heat materials or objects. It is widely used in metal, ceramics, glass, petrochemical and other industries. Refractory composite clay bricks for heating furnaces are a type of refractory material specially designed for use in high-temperature environments.

[0003] Some existing refractory composite clay bricks need to be installed inside a heating furnace when in use. When installing the refractory composite clay bricks, multiple bricks are directly stacked together. This installation method makes it difficult to align and fix the two bricks. Moreover, when the refractory composite clay bricks are connected together, there are certain gaps between the multiple refractory composite clay bricks in the direct placement method, which affects the sealing of the refractory brick structure and may cause gas or smoke leakage. Utility Model Content

[0004] The present application provides a refractory composite clay brick structure for a heating furnace. When using refractory composite clay bricks, it is easier to align and fix during installation, ensuring the stability of the overall structure and improving work efficiency. When connected together, it can reduce gaps, improve the sealing of the refractory structure, and prevent gas or smoke leakage.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a refractory composite clay brick structure for a heating furnace, the structure comprising:

[0006] Brick body;

[0007] A first fixing plate is fixedly mounted on one side of the brick body, and a notch is provided on one side of the first fixing plate. The positioning plate on one brick body is inserted into the interior of the first fixing plate on another brick body, thereby further connecting the multiple brick bodies together on the left and right sides.

[0008] A positioning plate is fixedly arranged on the brick body, the positioning plate is away from a side of the first fixing plate, and the positioning plate matches the notch;

[0009] A second fixing plate is fixedly arranged on one side of the brick body, and one side of the second fixing plate is provided with two grooves, and two square columns are inserted into the two grooves to connect the multiple brick bodies together;

[0010] The hollow plate is fixedly arranged on the side of the brick body away from the second fixing plate. The second fixing plate is inserted into the interior of the hollow plate, and the two square columns are further inserted into the interior of the two grooves to connect the multiple brick bodies together.

[0011] As a further improvement scheme of the present application: the inner wall of the groove matches the positioning plate, two square columns are fixedly provided on one side of the brick body, the positioning plate matches the groove, and the positioning plate on one brick body is inserted into the inside of the first fixed plate on another brick body to further connect multiple brick bodies together on the left and right.

When connected together, the gap can be reduced, the sealing of the refractory structure can be improved, and gas or smoke leakage can be prevented.

[0020] 2. In the present application, when using refractory composite clay bricks, the material of the two thermal insulation layers is ceramic powder. By coating the ceramic powder on both sides of the brick body, it becomes the outer layer structure of the brick body. Ceramics have excellent high temperature resistance and mechanical strength, which improves the heat resistance and strength of the brick body.

The material of the two insulating layers 301 is ceramic powder. By coating the ceramic powder on both sides of the brick body 1, it becomes the outer layer structure of the brick body 1. Ceramics have excellent high temperature resistance and mechanical strength, which improves the heat resistance and strength of the brick body 1. The two insulating layers 301 construct the middle layer of the brick body 1 to form an insulating barrier, which makes it difficult for heat to dissipate through the brick body, thereby improving the overall thermal insulation performance of the brick body 1.

When using refractory composite clay bricks, the material of the two thermal insulation layers 301 is ceramic powder. By applying the ceramic powder on both sides of the brick body 1, it becomes the outer layer structure of the brick body 1. Ceramics have excellent high temperature resistance and mechanical strength, which improves the heat resistance and strength of the brick body 1. The two thermal insulation layers 301 construct the middle layer of the brick body 1 to form an insulation barrier, making it difficult for heat to dissipate through the brick body, thereby improving the overall thermal insulation performance of the brick body 1. The material of the two thermal insulation layers 301 is silicate fiber. The material of the two reinforcing layers 302 is calcium aluminate cement, which has high strength and fire resistance and is suitable for high temperature environments. It becomes the inner layer of the brick body 1, improves the mechanical strength of the refractory bricks, and withstands greater pressure. The hollow grooves 303 make the interior of the brick body 1 vacuum, which can alleviate the thermal stress caused by temperature changes, reduce the risk of cracks and damage caused by thermal shock, and extend the service life of the brick body. At the same time, the two hollow grooves 303 make the brick body 1 lighter, which helps to reduce the burden on the overall building structure and facilitates installation.
