Abstract
The utility model relates to high-temperature cellar inner lining of furnace mullite brick, its structure comprises brick body, brick body is provided with self assembly mechanism for the two sides of splicing, self assembly mechanism is made up of the projection of mutual clamping and groove, protruding and brick body junction is provided with retention mechanism, and retention mechanism comprises bolt and is arranged on the connecting hole in brick body and projection.The utility model structure is simple, and the projection of mutual clamping and groove can self assemblies, does not need to adopt aluminate cement to make bonding agent and namely reaches and connect object closely, substantially increase the structural strength of furnace lining; And mullite is a kind of refractory material of high-quality, there is features such as expanding evenly, high-temerature creep value is little, hardness is large, resistance to chemical corrosion is good, with mullite brick as high-temperature cellar inner lining of furnace, greatly extended in the service life of inner lining structure.
Description
Technical field
The utility model belongs to fire resisting material field, particularly relates to a kind of high-temperature cellar inner lining of furnace mullite brick.
Background technology
In a lot of high temperature kiln, all need to use a large amount of indefinite form materials or refractory brick as liner.The furnace lining of firebrick structure is owing to connecting defective tightness between refractory brick, heat insulation effect is poor, bonding agent is made according to aluminate cement, because the CaO in aluminate cement at high temperature forms the submellite of low melting point, the serviceability temperature of serious reduction castable and structural strength, therefore the connecting portion of refractory brick is position the weakest in furnace lining, and first the destruction of furnace lining often occur herein.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of novel high-temperature cellar inner lining of furnace mullite brick, solve the above problems.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of structure simple, can self assembly, the high-temperature cellar inner lining of furnace mullite brick of long service life.
The utility model high-temperature cellar inner lining of furnace mullite brick, comprise brick body, described brick body is provided with self assembly mechanism for the two sides of splicing, described self assembly mechanism is made up of the projection of mutual clamping and groove, described projection and brick body junction are provided with retention mechanism, and described retention mechanism comprises bolt and is arranged on the connecting hole in brick body and projection.
Further, described brick body is linear for the cross section of the two sides of splicing.
Further, described brick body is stairstepping for the cross section of the two sides of splicing.
Further, the cross section of described projection and groove is the circle adapted.
Further, the cross section of described projection and groove is adapt trapezoidal.
Further, the cross section of described projection and groove is the T-shaped adapted.
Further, through hole is provided with in described brick body.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, and the projection of mutual clamping and groove can self assemblies, do not need to adopt aluminate cement to make bonding agent and namely reach and connect object closely, substantially increase the structural strength of furnace lining; Projection can change, and extends the service life of brick body; And mullite is a kind of refractory material of high-quality, there is features such as expanding evenly, high-temerature creep value is little, hardness is large, resistance to chemical corrosion is good, with mullite brick as high-temperature cellar inner lining of furnace, greatly extended in the service life of inner lining structure.
Accompanying drawing explanation
Fig. 1 is the first structural representation that is protruding and groove of the utility model;
Fig. 2 is the structural representation of the utility model the second projection and groove;
Fig. 3 is the third structural representation that is protruding and groove of the utility model;
Fig. 4 is the structural representation of the utility model the 4th kind of projection and groove.
In figure: 1, brick body; 2, protruding; 3, groove; 4, through hole; 5, bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See shown in Fig. 1 to Fig. 4, high-temperature cellar inner lining of furnace mullite brick shown in the utility model, comprise brick body 1, brick body 1 is provided with self assembly mechanism for the two sides of splicing, and self assembly mechanism is made up of the projection 2 of mutual clamping and groove 3, and protruding 2 are provided with retention mechanism with brick body 1 junction, retention mechanism comprises bolt 5 and is arranged on the connecting hole on brick body 1 and protruding 2, after damaging because expanding with heat and contract with cold when protruding 2, can change, simple and convenient; Brick body 1 is linear or stairstepping for the cross section of the two sides of splicing.When brick body 1 is stairstepping for the cross section of the two sides of splicing, can prevent the high-temperature gas in high-temperature cellar stove from leaking with brickwork joint, better save the heat in the stove of cellar for storing things.
Described protruding 2 and the cross section of groove 3 be coadapted circle, or trapezoidal, or T-shaped.
Through hole 4 is provided with, for alleviating the deadweight of brick body 1 in described brick body 1.
High-temperature cellar inner lining of furnace mullite brick shown in the utility model, structure is simple, and the projection 2 of mutual clamping and groove 3 can self assemblies, does not need to adopt aluminate cement to make bonding agent and namely reaches and connect object closely, substantially increase the structural strength of furnace lining; Protruding 2 can change, and extend the service life of brick body 1; Mullite is a kind of refractory material of high-quality, there is features such as expanding evenly, thermal shock resistance is fabulous, load softening point is high, high-temerature creep value is little, hardness is large, resistance to chemical corrosion is good, with mullite brick as high-temperature cellar inner lining of furnace, greatly extended in the service life of inner lining structure.
Comprise the above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
