Abstract
The utility model discloses a kind of low heat conduction refractory brick, comprise flame retardant coating and heat-insulation layer, described heat-insulation layer and flame retardant coating are by being suppressed into one, described heat-insulation layer is provided with the through hole of through heat-insulation layer both sides end face, one side end face of described heat-insulation layer is provided with groove, and the opposite side end face of described heat-insulation layer is provided with the projection with groove corresponding matching.The utility model has better heat dispersion, and the life-span is longer.
Description
Technical field
The utility model relates to a kind of low heat conduction refractory brick.
Technical background
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.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of low heat conduction refractory brick, and have better heat dispersion, the life-span is longer.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of low heat conduction refractory brick, comprise flame retardant coating and heat-insulation layer, described heat-insulation layer and flame retardant coating are by being suppressed into one, described heat-insulation layer is provided with the through hole of through heat-insulation layer both sides end face, one side end face of described heat-insulation layer is provided with groove, and the opposite side end face of described heat-insulation layer is provided with the projection with groove corresponding matching.
Preferably, the cross section of described through hole is rectangle.
Preferably, the quantity of described groove and projection is respectively two, and two grooves are arranged at the both sides up and down of through hole respectively.
The beneficial effects of the utility model are:
Adjacent refractory brick is connected with projection by groove, connect fastening between refractory brick, make the through hole of adjacent refractory brick be communicated with, heat-insulation layer carries out cross-ventilation by through hole, improves radiating effect simultaneously, 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.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, the utility model comprises flame retardant coating 1 and heat-insulation layer 2, described heat-insulation layer and flame retardant coating are by being suppressed into one, described heat-insulation layer is provided with the through hole 201 of through heat-insulation layer both sides end face, one side end face of described heat-insulation layer is provided with groove 202, and the opposite side end face of described heat-insulation layer is provided with the projection 203 with groove corresponding matching.The cross section of described through hole 201 is rectangle, and the efficiently radiates heat area of rectangle is comparatively large and make the weight loss effect of refractory brick obvious.The quantity of described groove 202 and projection 203 is respectively two, and two grooves are arranged at the both sides up and down of through hole 201 respectively, and this structure makes to combine firmly between adjacent refractory brick, not easily gets loose.
Principle of the present utility model:
Adjacent refractory brick is connected with projection by groove, connect fastening between refractory brick, make the through hole of adjacent refractory brick be communicated with, heat-insulation layer carries out cross-ventilation by through hole, improves radiating effect simultaneously, 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.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is restriction to claim.The utility model is not only confined to above embodiment, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all belong to the scope that the utility model claims define.
