Description
Technical field
The utility model relates to a kind of high temperature kiln refractory brick, particularly relates to the improvement of vaulted type tunnel kiln dome brick structure.
Background technology
Tunnel cave can be divided into vault, couter-ceiling and three kinds, hanging arch top version by kiln roof construction.Because vault in the tunnel cave of vaulted type structure and insulation material thereof are directly set up on kiln wall by arch springing, vault does not need the suspender member of metal, therefore the tunnel cave of vault construction is compared with couter-ceiling tunnel cave, structure is relatively simple, air-tightness is good, steel consumption amount is little, and construction investment is less.
But the vault of vault tunnel cave exists Level Promoting to kiln wall, this horizontal thrust becomes large along with the increase of kiln top weight, and the gas flow temperature at arch crown place is again higher than near-bottom temperature in kiln simultaneously, therefore the ceiling brick higher flue-gas temperature of tolerance and kiln temperature.And existing tunnel kiln top often adopts heavy firebrick arch to build forms, increasing the weight of of refractory brick own wt, arched top is made to there is very large side direction horizontal thrust to both sides kiln wall, the impact of in addition being expanded with heat and contract with cold, it is outward-dipping that both sides Yao Qiang is easy to generation, kiln top can be caused to sink, sink to a certain extent time serious, kiln top just there will be and caves in, and causes production accident.Therefore improve the heat-resisting heat-insulating property of vault tunnel kiln dome brick, and reduce the technical barrier that ceiling brick weight becomes industry long sought.
Utility model content
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of refractory brick with composite adiabatic structure, and this refractory brick not only quality is light, and heat-insulating property is excellent.
In order to solve the problems of the technologies described above, the refractory brick with composite adiabatic structure of the present utility model, comprise refractory brick body, this refractory brick body is hexahedron, the cross section of described refractory brick body is isosceles trapezoid, be respectively equipped with grafting tenon and grafting groove at two waists of this isosceles trapezoid, this grafting tenon and grafting groove are arranged along the length direction of refractory brick body; In refractory brick body, be also provided with aeroge packed layer and refractory fibre packed layer, aeroge packed layer is near the upper bottom side of refractory brick body, and refractory fibre packed layer is then near the lower bottom side of refractory brick body.
In said structure, because this body section of refractory brick is in isosceles trapezoid, the refractory brick of this structure can form the arch kiln roof construction of symmetrical equilibrium when building by laying bricks or stones, has both been beneficial to the stable of kiln roof construction, again can the stress equalization on whole kiln top reasonable.Again owing to being respectively equipped with grafting tenon and grafting groove at two waists of isosceles trapezoid, when key brick is built by laying bricks or stones, can engage each other with tenon and groove between brick with brick and be connected.The engagement of brick body closely, strong in conjunction with connection, vault good integrity, even if brickwork joint produces to shrink and also not easily occurs falling brick under high temperature or cooling operating mode, mutual feather joint simultaneously between fragment of brick has blocked again the thermal source such as high-temperature flue gas, flame along the infiltration in gap with gang up, there is good heat insulating effect, substantially increase the thermal efficiency of tunnel cave.Also owing to being provided with aeroge packed layer and refractory fibre packed layer in refractory brick body, aeroge on the one hand in aeroge packed layer and refractory fibre packed layer and the density of refractory fibre are all much smaller than the density of refractory brick material, so just significantly reduce the weight on refractory brick and kiln top thereof, and the reduction of vault weight alleviates the transverse horizontal thrust of vault to kiln wall, not only increase the security performance of kiln, extend the service life of kiln body, and tunnel kiln chamber width can be increased.The refractory heat-insulating performance of aeroge and refractory fibre is again much larger than refractory brick body heat-insulating property on the other hand, especially the aeroge adopted in this configuration is the solid-state material of current heat-insulating property the best, and its nanometer porous network structure effectively can limit solid state heat conduction and gaseous heat conduction; Cellulosic refractory material also has lightweight, fusing point and softening point is high, heat-proof quality is good, is easy to the advantage of machine-shaping.Because in the vault of tunnel cave, the small end (upper bottom side) of its refractory brick is the hot active side in face, therefore by the upper bottom side of aeroge packed layer near refractory brick body, be conducive to playing the superadiabatic performance of aeroge, the large end (lower bottom side) that refractory fiber floor is positioned at refractory brick body then can play again that Anti-pull-press mechanical property is excellent, the advantage of good thermal shock.Therefore, refractory brick of the present utility model, adopts the heat insulation heat insulating construction of compound, has light weight, high adiabatic Multiple techniques effect.
Further embodiment of the present utility model, the shape size of described grafting tenon and grafting groove is mutually corresponding.This structure can realize the engagement joggle of adjacent refractory brick easily, is convenient to make and construction.
A kind of preferred embodiment of the present utility model, described grafting tenon cross section is the semi-cylindrical form of evagination.Described grafting groove is the half slot of indent.Circular arc tenon and tongue-and-groove, be not only convenient to make processing, and have good engagement sealing.
