Description

Technical Field

[0001] This utility model relates to the field of mullite brick structure technology, and in particular to a high-strength mullite brick. Background Technology

[0002] Mullite bricks are high-alumina refractory materials with mullite as the main crystalline phase. They typically contain 65%-75% alumina. Besides mullite, those with lower alumina content also contain small amounts of glass and cristobalite, while those with higher alumina content also contain small amounts of corundum. They are mainly used in hot blast stove roofs, blast furnace bodies and bottoms, glass melting furnace regenerators, ceramic sintering kilns, and dead-angle furnace linings in petroleum cracking systems.

[0003] A search revealed that authorization announcement number CN219956111U discloses a high-strength mullite brick, relating to the field of mullite brick technology. The brick includes a brick body with a reinforcing assembly inside. The reinforcing assembly includes a reinforcing cylinder, supporting ribs, connecting ribs, reinforcing parts, and first limiting blocks. Several reinforcing cylinders are installed inside the brick body, several supporting ribs are fixedly installed at both ends of the corresponding outer wall of the reinforcing cylinder, connecting ribs are fixedly installed on one side of the corresponding supporting rib, several reinforcing parts are fixedly installed on the inner wall of the reinforcing cylinder, and several first limiting blocks are fixedly installed on the outer wall of the reinforcing cylinder. In the technical solution provided by this utility model, the two ends of the reinforcing cylinder support the two ends of the brick body. One side of the supporting rib is located on both sides of the brick body, and the supporting rib is connected to the reinforcing cylinder through the connecting rib. The connecting rib is located inside the brick body, supporting the supporting rib. When two bricks are connected, the supporting rib is located between the two bricks, supporting the brick body, reducing the load-bearing force between the bricks, increasing the strength of the brick body, and increasing the service life of the brick body.

[0004] However, existing mullite bricks are solid structures, which results in poor thermal insulation and low structural strength, thus affecting their performance. Therefore, there is an urgent need in the market for a higher-strength mullite brick to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength mullite brick to solve the problems mentioned in the background art, which are that existing mullite bricks are solid structures, resulting in poor thermal insulation and low structural strength, thus affecting the performance of the mullite bricks.

[0014] By adopting the above technical solution, the mullite brick body can be supported by strengthening the support frame, thereby increasing the structural strength of the mullite brick body.

[0015] Furthermore, twelve vertical support seats are provided, and the twelve vertical support seats are symmetrical about the vertical center line of the horizontal support seats and the horizontal support seats, and the vertical support seats are welded to the horizontal support seats.

[0016] By adopting the above technical solution, welding can make the structure between the vertical support and the horizontal support more robust, which can improve the support effect on the mullite brick body and thus improve the structural strength of the mullite brick body.

[0017] Furthermore, one end of the vertical support base is provided with a limiting support end, which is an integral structure with the vertical support base, and one end of the limiting support end is located inside the limiting installation chamber.
