Abstract
The utility model discloses a prefabricated brick for an inner liner of a rotary kiln. The prefabricated brick comprises a brick body and an anchoring part, wherein a metal component is arranged in the brick body in a length direction; the metal component is connected with the anchoring part which penetrates through the brick body; and the anchoring part penetrates through the external surface of the brick body to stretch out of the brick body. When the prefabricated brick is heated, the expansion of the brick body changes in the length direction under the influence of the metal part, the effect of the internal stress of the anchoring part to the strength of the prefabricated brick after the temperature of the rotary kiln is raised is reduced, and the service life of the prefabricated brick is prolonged.
Description
Technical field
The utility model relates to a kind of fire-resistant heat insulating material, relates to specifically the preformed bricks that a kind of inner liner of rotary kiln is used.
Background technology
at present, in existing rotary kiln domestic demand, a large amount of preformed bricks is set, every preformed bricks is connected with cylinder of rotary kiln by the jointing that exposes, heat-resisting aspect in the kiln that formation is comprised of preformed bricks, and the structure of preformed bricks commonly used is that the cross section is trapezoidal four bank or ridge, at inner pre-buried two anchoring pieces of the preformed bricks of rotary kiln, trapezoidal portions is embedded in preformed bricks, after finding in the production and application process that anchoring piece is heated, its horizontal component expands and lengthens, make preformed bricks top section generation stress, be easy to occur the loosening or fracture of the efflorescence of refractory material, in a single day post-rift refractory material remains come off and will affect the service life of rotary kiln.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the preformed bricks that a kind of inner liner of rotary kiln is used, and this brick can reduce after the anchoring piece expanded by heating impact on preformed bricks, the service life of improving preformed bricks.
To achieve these goals, the technical solution adopted in the utility model is: the preformed bricks that a kind of inner liner of rotary kiln is used, comprise brick body and anchoring piece, suitable long to being provided with hardware in described brick body, hardware be connected by the anchoring piece in the brick body, anchoring piece passes the external aspect of brick, and to extend to brick external.
Preferably, described brick body nexine counter-fire face is brushed with the radiation heat insulation energy-saving coating.
Preferably, described hardware is stainless-steel sheet.
Preferably, the extension of described anchoring piece is provided with screw thread.
Compared with prior art, the utility model has the advantages that: preformed bricks of the present utility model is after being heated, the expansion of brick body is changed to direction along long by the impact of hardware, reduce kiln temperature and improved the internal stress of rear anchor piece to the impact of preformed bricks intensity, the service life of having improved preformed bricks.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, brick body; 2, hardware; 3, anchoring piece.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the preformed bricks that inner liner of rotary kiln of the present utility model is used comprises brick body 1 and anchoring piece 3, and described brick body 1 is interior suitable long to being provided with hardware 2, hardware 2 be connected by the anchoring piece 3 in brick body 1, anchoring piece 3 passes brick body 1 outer layer surface and extends to outside brick body 1.Described brick body 1 nexine counter-fire face is brushed with the radiation heat insulation energy-saving coating.Described hardware 2 is stainless-steel sheet.The extension of described anchoring piece 3 is provided with screw thread.
During use, this preformed bricks is stretched out anchoring piece 3 terminations of exposing be connected with cylinder of rotary kiln, contact at the trapezoidal inclined plane place between brick body 1 and brick body 1, build by laying bricks or stones with the high temperature adhesive fissure of displacement, form complete rotary kiln bore area layer.
Above-mentioned is only a kind of embodiment of the present utility model; not in order to limit the utility model; those skilled in the art can make various changes and improve said structure; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (4)
1. the preformed bricks that inner liner of rotary kiln is used, comprise brick body and anchoring piece, it is characterized in that: in described brick body along long to being provided with hardware, hardware be connected by the anchoring piece in the brick body, anchoring piece passes the external aspect of brick, and to extend to brick external.
2. the preformed bricks used of inner liner of rotary kiln according to claim 1, it is characterized in that: described brick body nexine counter-fire face is brushed with the radiation heat insulation energy-saving coating.
