Description
Technical field
The utility model relates to flame-proof thermal insulation material field, specifically a kind of insulating fire brick.
Background technique
Refractory brick is applied to the every field of the national economy such as steel, non-ferrous metal, glass, cement, ceramics, petrochemical industry, is
Guarantee that above-mentioned industry production run and technology develop essential basic material, is played not in hot industry production development
Alternative important function.Refractory brick abbreviation firebrick is the refractory material being fired into refractory clay or other refractory raw materials.
Inner lining refractory block used in general Industrial Stoves is divided into working face (hot end) and non-working surface (cold end), and working face one end is towards kiln
Furnace interior and metal-back of the non-working surface one end towards kiln.The metal shell of kiln is easy heated shape in long-term work
Become, and the metal shell after deformation can generate extruding to the refractory brick in kiln, and then influence the service life of refractory brick, kiln
Therefore problem can also occur for furnace, or even the operation that cannot work on.Therefore it generally will be close to the refractory brick at kiln enclosure location
It is set as heat-insulated, to reduce in heat transmission to the metal shell of kiln.
Utility model content
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of insulating fire brick, this kind of fire resisting
Brick heat-proof quality is good, and than stronger.
To solve prior art problem, the utility model discloses a kind of insulating fire bricks, including brick body, inside brick body
One cavity is set, the hollow circular-tube connected in length and breadth is provided in the cavity, the hollow circular-tube is closed at both ends, and inside is filled with
Air, the hollow circular-tube extend in the castable of brick body；The bottom of brick body is provided with several fins.
Preferably, the cavity is arranged at the position in the middle part of brick body on the lower.
Preferably, the hollow circular-tube in the cavity includes transversely arranged round tube and vertically disposed round tube, the cross
To arrangement round tube perpendicular to vertically disposed round tube.
Preferably, stuffed heat insulated cotton in the cavity.
Preferably, the fin is parallel to the short side of brick body bottom surface.
The utility model has the beneficial effects that: an aerial cavity is arranged inside brick body, can fill in cavity every
Hot cotton can not also fill, and there is only air, and the hollow circular-tube connected in length and breadth is provided in cavity, is filled in round tube
Air；Air is the non-conductor of heat, can effectively completely cut off the transmission of heat.And the hollow circular-tube connected in length and breadth can also rise
To the effect for reinforcing brick body fastness, reinforcing rib use can be used as；Several fins are additionally provided in the bottom of brick body, it is described convex
The bottom surface that rib height is higher than brick body can play heat-insulated effect, while can also increase in the metal shell for being installed to kiln
Add the contact area with binder, makes to be more firmly mounted.
In the utility model, it is clear that, be working face at the top of brick body, should be towards kiln inside, and the bottom of brick body
Portion is non-working surface, should be towards the metal shell of kiln.Correspondingly, cavity and fin are arranged at bottom surface (non-work
Make face) side, convenient for heat-insulated.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the attachment structure schematic diagram of hollow circular-tube in the utility model；
Fig. 3 is the structural schematic diagram of brick body bottom fin in the utility model.
Appended drawing reference:
1, brick body；2, cavity；3, hollow circular-tube；4, fin.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown, a kind of insulating fire brick, including brick body 1, a cavity 2 is set inside brick body 1, in the cavity 2
It is provided with the hollow circular-tube 3 connected in length and breadth, the hollow circular-tube 3 is closed at both ends, and inside is filled with air, the hollow circular-tube 3
It extends in the castable of brick body 1；The bottom of brick body 1 is provided with several fins 4.
Cavity 2 is arranged at the position of 1 middle part of brick body on the lower, and the hollow circular-tube 3 in the cavity 2 includes transversely arranged
Round tube and vertically disposed round tube, the transversely arranged round tube is perpendicular to vertically disposed round tube.
Stuffed heat insulated cotton in cavity 2, fin 4 are parallel to the short side of 1 bottom surface of brick body.
The utility model has the beneficial effects that: an aerial cavity 2 is arranged inside brick body 1, can be filled in cavity 2
Heat insulation foam can not also fill, and there is only air, the hollow circular-tube 3 connected in length and breadth is provided in cavity 2, is filled out in round tube
Filled with air；Air is the non-conductor of heat, can effectively completely cut off the transmission of heat.And the hollow circular-tube 3 connected in length and breadth is also
It can play the role of reinforcing 1 fastness of brick body, can be used as reinforcing rib use；It is additionally provided in the bottom of brick body 1 several convex
Rib 4, the bottom surface that 4 height of fin is higher than brick body 1 can play heat-insulated effect in the metal shell for being installed to kiln,
The contact area with binder can also be increased simultaneously, make to be more firmly mounted.
In the utility model, it is clear that, the top of brick body 1 is working face, should towards kiln inside, and brick body 1
Bottom is non-working surface, should be towards the metal shell of kiln.Correspondingly, cavity 2 and fin 4 are arranged at bottom surface
(non-working surface) side, convenient for heat-insulated.
Obvious, hollow circular-tube 3 described in the utility model can be made of metal, can also be using materials such as ceramics
Material is made.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
