Abstract

The utility model discloses a durable light fire brick: including flame retardant coating and heat preservation, the heat preservation is as an organic whole through suppressing into with the flame retardant coating, there is the efficient heat conduction cylinder of a heat -conduction to run through two -layer between flame retardant coating and the heat preservation, be equipped with the through -hole that link up the heat preservation on the heat preservation, the through -hole is the guide plume body even, link up each other, through -hole inner structure is the wave. Because have the heat conduction cylinder that runs through two -layer for its combination is inseparabler, in addition, can be by the slow steady heat conduction of flame retardant coating to heat preservation, heat preservation the thermal expansion degree alleviates, and the heat preservation is difficult for tearing with the flame retardant coating faying face, has improved the life of refractory brick, the heat preservation carries out the air convection through the wave through -hole simultaneously, and heat dissipation and heat preservation obtain balancedly, can reach good heat preservation effect, the setting of through -hole has simultaneously still alleviateed weight.

Description

A kind of durable light fire brick
Technical field
The utility model relates to a kind of refractory brick, particularly the durable light fire brick of one.
Background technology
Refractory brick conventional in rotary kiln generally includes flame retardant coating and heat-insulation layer, flame retardant coating face side towards the fire, heat-insulation layer towards building brick, for thermal insulation protection.But because heat-insulation layer heat dispersion is poor, easy expanded by heating, causes the faying face of heat-insulation layer and flame retardant coating to be torn, shortens the life-span of refractory brick in high temperature environments.
Prior art is disclosed a kind of low heat conduction refractory brick, heat-insulation layer is provided with the huge through hole of through heat-insulation layer both sides end face to accelerate heat radiation, its advantage is: improve radiating effect, thus the thermal and insulating performance of heat-insulation layer is got a promotion, heat-insulation layer expanded by heating degree alleviates, and heat-insulation layer and flame retardant coating faying face are not easily torn, and improve the service life of refractory brick, simultaneously through hole the quality that page alleviates refractory brick is set, reduce cost.Dispel the heat and too fastly just lose the meaning of heat-insulation layer.
The present invention aims to provide a kind of durable, the light fire brick of high insulating effect again.
Utility model content
Based on the technical problem that background technology exists, the utility model, for the shortcoming of existing refractory brick, provides a kind of new light fire brick.
The technical solution of the utility model is as follows:
A kind of durable light fire brick, is characterized in that:
Comprise flame retardant coating and heat-insulation layer, described heat-insulation layer and flame retardant coating are by being suppressed into one;
The heat conduction cylinder that described flame retardant coating and heat-insulation layer directly have a heat conduction efficiency high runs through two-layer;
Described heat-insulation layer is provided with the through hole of through heat-insulation layer, and described through hole connects to heating column body, through each other;
Described through hole internal structure is waveform.
Further, described heat conduction cylinder is made up, as magnesia brick of the special quality fire-brick that heat transfer efficiency is high.
Usefulness of the present utility model is:
Durable light fire brick of the present invention, because have the heat conduction cylinder running through two-layer, makes its combination tightr; In addition, can by the slow steady heat conduction of flame retardant coating to heat-insulation layer, heat-insulation layer expanded by heating degree alleviates, and heat-insulation layer and flame retardant coating faying face are not easily torn, and improve the service life of refractory brick; Heat-insulation layer carries out cross-ventilation by waveform through hole simultaneously, and heat radiation and insulation are balanced, and can reach excellent heat insulation effect; The setting of through hole simultaneously also reduces weight.
Accompanying drawing explanation
Fig. 1 is the structural representation of durable light fire brick of the present utility model.
Fig. 2 is the cross section structure schematic diagram of heat-insulation layer through hole and heat conduction cylinder.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, durable light fire brick of the present utility model, is characterized in that: comprise flame retardant coating 1 and heat-insulation layer 2, and described heat-insulation layer and flame retardant coating are by being suppressed into one;
The heat conduction cylinder 3 having a heat conduction efficiency high between described flame retardant coating and heat-insulation layer runs through two-layer;
Described heat-insulation layer is provided with the through hole 4 of through heat-insulation layer, and described through hole connects to heating column body, through each other;
As shown in Figure 2, described through hole 4 internal structure is waveform, and through heat conduction cylinder.
Described heat conduction cylinder is made up, as magnesia brick of the special quality fire-brick that heat transfer efficiency is high.
Durable light fire brick of the present invention, because have the heat conduction cylinder running through two-layer, makes its combination tightr; In addition, can by the slow steady heat conduction of flame retardant coating to heat-insulation layer, heat-insulation layer expanded by heating degree alleviates, and heat-insulation layer and flame retardant coating faying face are not easily torn, and improve the service life of refractory brick; Heat-insulation layer carries out cross-ventilation by waveform through hole simultaneously, and heat radiation and insulation are balanced, and can reach excellent heat insulation effect; The setting of through hole simultaneously also reduces weight.
The above; be only the utility model preferably detailed description of the invention; 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; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
