Description

Technical Field

[0001] The utility model relates to the technical field of corundum mullite brick production equipment, in particular to a re-rolling device for producing corundum mullite bricks. Background Art

[0002] Corundum mullite bricks refer to refractory products with an alumina content greater than 90% and corundum as the main crystal phase. They have high room temperature compressive strength and high load softening starting temperature, as well as good chemical stability. They are widely used in various high-temperature kiln linings and kiln furniture in the petrochemical and fertilizer industries, such as cracking furnaces, converters, and metallurgical industries.

[0003] In the production process of corundum mullite bricks, the raw materials of the bricks need to be rolled back and forth in the brick mold so that the stones are tightly filled inside the brick mold to facilitate the molding of the bricks.

[0004] Chinese patent publication number CN220428789U discloses a special corundum mullite brick production and rolling device, including: a base, a rolling component and a bracket. The rolling component can roll the material, thereby processing the material into shape. The lifting mechanism includes a bearing platform, a lower cylinder is installed at the bottom of the bearing platform, and a mouth frame is connected to the outer wall of the bearing platform. When the material is placed on the surface of the bearing platform, the piston rod end of the lower cylinder can drive the bearing platform to rise, thereby cooperating with the rolling component to strengthen the extrusion of the material. This special corundum mullite brick production and rolling device, when the rolling component rolls the material, is driven by the upper cylinder to descend and press on the surface of the material. At the same time, the driving component drives the rolling component to perform a back and forth motion. At this time, the rolling component rolls on the surface of the material, thereby rolling and shaping the material.

[0005] The lower cylinder moves the supporting platform downward, so that the supporting platform is away from the crushing component, so as to facilitate the removal of the stone. However, this removal method can only move the material in the vertical direction. When removing the material, manual or mechanical exploration is required to reach the bottom side of the crushing mechanism to remove the material, which is less safe. Summary of the Invention
