Abstract
The utility model discloses a composite brick for an active lime rotary kiln, which belongs to a furnace lining material of the rotary kiln, and mainly overcomes defects of the existing composite brick that the junction between a heat-insulating layer and a work layer is poor and the connection between brick bodies is loose. The composite brick comprises a brick body consisting of a heat-insulating layer and a work layer, and is characterized in that a junction surface between the heat-insulating layer and the work layer employs gear shape or small arc shape occlusive connection. The utility model is simple in structure, the junction surface between the heat-insulating layer and the work layer employs gear shape or small arc shape occlusive connection, the junction strength of the junction surface of the composite brick can be improved, and the capability of resisting shearing force breakage of the composite brick can also be greatly enhanced. Two end faces of the brick body are provided with right-angle lock catch steps, so a lock catch structure with mutual locking can be formed between the brick bodies, and the whole junction strength can be improved.
Description
Technical field
The utility model belongs to the furnace lining material of rotary kiln, in particular for the composite brick of active lime rotary kiln.
Background technology
The composite brick that is used for rotary kiln is made of thermal insulation layer and working lining, is sector structure, and wherein, the faying face between thermal insulation layer and the working lining is an arc surface, and heat insulation laminating is built on the inwall of cylindrical shell.The subject matter that exists is: 1. owing to be connected for arc surface between thermal insulation layer and the working lining, therefore, light heat insulation layer can not combine well with the heavy working lining, make thermal insulation layer in operation process, separate easily with working lining, cause peeling off and falling brick of composite brick, thereby influence the service life of kiln; 2. be connected insecurely between brick body and the brick body, bond strength is relatively poor.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, can improve the active lime rotary kiln composite brick that is connected firmly between thermal insulation layer and working lining bond strength and anti-shearing damage capability, brick body and the brick body.
The utility model is achieved in that and comprises the brick body that is made of thermal insulation layer and working lining, it is characterized in that the faying face between described thermal insulation layer and the working lining is that gear-like or little circular shape are connected.
Described brick body both ends of the surface are provided with right angle snap close step.
Faying face between thermal insulation layer of the present utility model and the working lining is that gear-like or little circular shape are connected, not only can improve the bond strength of composite brick faying face, and can improve the ability of the anti-shearing force destruction of composite brick greatly, thereby the service life of improving kiln.Be set to right angle snap close step by brick body both ends of the surface, can make to form the buckle structure of tight lock mutually between brick body and the brick body, promptly form domain brick, thereby improve whole bond strength.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic diagram.
Among the figure: 1-brick body (1a-working lining, 1b-thermal insulation layer), 2-right angle snap close step, 3-faying face, 4-cylinder of rotary kiln.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: the working lining 1a and the faying face 3 between the thermal insulation layer 1b of brick body 1 are connected with gear-like or little circular shape, and the both ends of the surface of brick body 1 are provided with right angle snap close step 2 promptly becomes the utility model.
During brickmaking, working lining 1a can adopt the high-alumina brick material of anti-strip, and thermal insulation layer 1b can adopt and add flint clay and float the light thermal-insulation brick of pearl, with working lining 1a and the compression molding of thermal insulation layer 1b one, can use after the oven dry, without high temperature sintering at normal temperatures.
Claims (2)
1. an active lime rotary kiln composite brick comprises the brick body that is made of thermal insulation layer and working lining, it is characterized in that the faying face between described thermal insulation layer and the working lining is that gear-like or little circular shape are connected.
2. by the described active lime rotary kiln of claim 1 composite brick, it is characterized in that described brick body both ends of the surface are provided with right angle snap close step.
