Description

Technical Field

[0001] The utility model relates to the technical field of magnesia carbon bricks, in particular to a magnesia carbon brick with waterproof performance. Background Art

[0002] As a high-performance refractory material, magnesia carbon bricks have been widely used in metallurgy, building materials, chemical industry and other industrial fields due to their excellent high temperature stability, corrosion resistance and strength. However, in actual use, especially in high humidity or open air environments, magnesia carbon bricks often face the problem of moisture penetration. Moisture penetration will not only cause the destruction of the internal structure of magnesia carbon bricks, but may also cause their performance to decline and even cause safety hazards.

[0003] In order to solve this problem, the traditional approach is usually to add waterproofing agents during the production process of magnesia carbon bricks, or to use waterproof coatings for surface coating after laying magnesia carbon bricks. However, these methods often have the following shortcomings:

[0004] First of all, although adding waterproofing agents can improve the waterproof performance of magnesia carbon bricks to a certain extent, it often affects its original high temperature performance and corrosion resistance, resulting in a decline in overall performance.

[0005] Secondly, although it is simple and easy to use waterproof coating for surface coating, the coating is prone to peeling and aging, the waterproof effect is difficult to last, and the maintenance cost is high.

[0006] Some existing magnesium carbon bricks are waterproofed by setting two layers of waterproof layers on the outside of the magnesium carbon brick body when in use. However, due to the wrapping of the waterproof layer, the magnesium carbon brick body cannot be directly contacted. After the magnesium carbon brick body is damaged, it is difficult to remove and replace it. The entire magnesium carbon brick assembly needs to be replaced, which increases maintenance costs.

[0007] For example, the publication number CN218321171U discloses a magnesium carbon brick with anti-hydration performance. This patent sets a first waterproof layer and a second waterproof layer. Since the first waterproof layer and the second waterproof layer are both set on the outside of the magnesium carbon brick body, the first waterproof layer and the second waterproof layer can have a good waterproof effect on the magnesium carbon brick body and can effectively prevent moisture from entering the interior of the magnesium carbon brick body, thereby enhancing the anti-hydration performance of the magnesium carbon brick body and enhancing the service life of the magnesium carbon brick body.

[0008] The MgO-C brick body is wrapped between two waterproof layers. Although this structure enhances the anti-hydration performance, it complicates the removal and replacement process after the MgO-C brick body is damaged. Due to the presence of the waterproof layer, the MgO-C brick body cannot be directly contacted, making it difficult to perform simple and quick replacement. Since the MgO-C brick body is difficult to remove and replace, once damaged, the entire MgO-C brick assembly may need to be replaced, not just the MgO-C brick body. This increases maintenance costs and may involve more time and manpower investment.

[0009] Therefore, it is necessary to invent a magnesia carbon brick with waterproof performance to solve the above problems. Utility Model Content

[0016] The bottom, top and side walls of the magnesia-carbon brick body are respectively in contact with the inner bottom surface of the waterproof storage box, the bottom of the waterproof sealing cover and the inner wall of the No. 1 isolation wall. This design can prevent the magnesia-carbon brick body from shaking inside the waterproof shell.

[0017] Preferably, the waterproof storage box is integrally formed with the first isolation wall, and the waterproof sealing cover is integrally formed with the second isolation wall.

[0018] The one-piece molding of the waterproof storage box and the No. 1 isolation wall, and the waterproof sealing cover and the No. 2 isolation wall simplifies the manufacturing process, reduces the connection gaps between components, and thus improves the stability and waterproof performance of the overall structure.

[0019] Preferably, one end of the waterproof storage box is fixedly connected to a No. 1 card block, and the other end of the waterproof storage box is fixedly connected to a No. 2 card block, and the No. 1 card block and the No. 2 card block can be snap-fitted and matched.

[0020] With the help of No. 1 clamp block and No. 2 clamp block, it is convenient to splice two magnesia carbon bricks left and right.

[0021] Preferably, the first card block and the second card block are both integrally formed with the waterproof storage box.

[0022] The one-piece molding of the No. 1 card block and the No. 2 card block with the waterproof storage box ensures the stability and durability of the card connection.

[0023] Preferably, the four bottom corners of the waterproof storage box are fixedly connected to a limiting sleeve frame, and the four top corners of the waterproof sealing cover are fixedly connected to a limiting card block, and the limiting sleeve frame and the limiting card block can be snap-fitted and matched.

When the magnesia carbon brick body is damaged, you only need to remove the waterproof sealing cover from the waterproof storage box to easily take out and replace the damaged magnesia carbon brick body without replacing the entire magnesia carbon brick assembly. This design greatly simplifies the replacement process, not only improves maintenance efficiency, but also significantly reduces maintenance costs;

[0029] 2.
