Description

Technical Field

[0001] The utility model belongs to the technical field of kilns, and relates to a refractory brick and a refractory brick splicing structure. Background Art

[0002] Refractory bricks are important materials for high-temperature waste treatment facilities such as brick kilns and incineration ponds. Taking a rotary kiln as an example, currently, the refractory bricks of rotary kilns are all spliced by adhesives. Since the rotary kiln is cylindrical and rotates during operation, this splicing method of refractory bricks is prone to brick detachment. High temperature and corrosion of hazardous waste substances on the filler in the brick joints are also likely to cause loosening of the refractory bricks. Content of the Utility Model

[0003] The purpose of the utility model is to provide a refractory brick for the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the splicing strength of the refractory brick.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A refractory brick, characterized in that it includes an inner wall surface, an outer wall surface, two first splicing surfaces and two second splicing surfaces. The inner wall surface and the outer wall surface are parallel and opposite to each other. The two first splicing surfaces are parallel and opposite to each other. The two second splicing surfaces are symmetric and opposite to each other. The middle of the second splicing surface has an arc-shaped limiting opening.

[0005] A refractory brick splicing structure, characterized in that the first splicing surfaces of two longitudinally adjacent refractory bricks are attached, and at least two laterally adjacent refractory bricks are connected by a connecting column, and the connecting column is adapted to the limiting opening.

[0006] The radian of the arc-shaped limiting opening is less than 180°, so that the refractory brick can rotate around the connecting column within a certain range to adapt to circular arc or other special-shaped splicing. For a rotary kiln, the limiting column is parallel to the axis of the kiln, and each limiting column is evenly distributed circumferentially outside the center line of the kiln.

[0007] Compared with the traditional method, for this type of refractory brick, there is no need to fill the splicing position with filler to bond the splicing surface at the second splicing surface. If there is peeling of the adhesive at other splicing surfaces, it will not cause the detachment of the refractory brick. Coupled with the extrusion between bricks, this method can greatly improve the splicing strength and simplify the splicing difficulty and splicing process. Description of the Drawings

[0013] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0014] As Figure 2 shown, the refractory brick includes an inner wall surface 1, an outer wall surface 2, two first splicing surfaces 3 and two second splicing surfaces 4. The inner wall surface 1 and the outer wall surface 2 are parallel and face each other. The two first splicing surfaces 3 are parallel and face each other. The two second splicing surfaces 4 are symmetric and face each other. The middle of the second splicing surface 4 has an arc-shaped limiting port 5.

[0015] As Figure 3 and Figure 4 shown, in the refractory brick splicing structure, the first splicing surfaces 3 of two longitudinally adjacent refractory bricks are attached, and at least two laterally adjacent refractory bricks are connected by a connecting column 6. The connecting column 6 is adapted to the limiting port 5.

[0016] The radian of the arc-shaped limiting port 5 is less than 180°, so that the refractory brick can rotate around the connecting column 6 within a certain range to adapt to circular arc or other special-shaped splicing. For a rotary kiln furnace as Figure 1 shown, the limiting columns are parallel to the axis of the kiln furnace, and each limiting column is circumferentially and evenly distributed outside the center line of the kiln furnace.

[0017] Compared with the traditional method, for this type of refractory brick, there is no need to fill the splicing position with fillers at the second splicing surface 4 to bond the splicing surface. If there is peeling of the bonding agent on other splicing surfaces, it will not cause the refractory brick to fall off. Coupled with the extrusion between bricks, this method can greatly improve the splicing strength and simplify the splicing difficulty and splicing process.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
