Description
Technical field
The utility model relates to a kind of composite fibre structure of ceramic fibre.
Background technology
At present, common insulation material is all emphasized its homogeneity, but the use occasion of insulation material has thermograde, and promptly hot side reduces gradually to the temperature of huyashi-chuuka (cold chinese-style noodles), and the hot side material requirements is higher, and the huyashi-chuuka (cold chinese-style noodles) material requirements is lower; If under same temperature conditions, particularly in the insulation construction that is not suitable for separating, the material of selecting for use must be the material that satisfies the thermal source face, and this cuts the insulation material of building and cost an arm and a leg energy consumption with regard to causing.
Summary of the invention
The utility model provides a kind of composite fibre structure of rational in infrastructure, service-strong ceramic fibre.
The purpose of this utility model is achieved through the following technical solutions:
The composite fibre structure of ceramic fibre, characteristics are: described composite fibre structure comprises hot-zone heat-insulation layer, inferior hot-zone heat-insulation layer and cold-zone heat-insulation layer successively, its structure is strip, arc shape, cylindric or cubic, is provided with heating in the heat-insulation layer of described hot-zone.
The composite fibre structure of above-mentioned ceramic fibre, described hot-zone heat-insulation layer is the polycrystalline mullite fibre layer.
The composite fibre structure of above-mentioned ceramic fibre, described hot-zone heat-insulation layer is polycrystalline mullite fibre and the compound ceramic fiber layer of 1260 alumina silicate fibres.
The composite fibre structure of above-mentioned ceramic fibre, described cold-zone heat-insulation layer are 1260 alumina silicate fibre layers.
The utility model has the advantages that:
The material of thermal source face is the hot-zone heat-insulation layer, and it is made up of high-grade ceramic fibrage and heating, or directly is the high-grade ceramic fibrage; Material between thermal source face and the low-temperature receiver face is a time hot-zone heat-insulation layer, and it is by the ceramic fiber layer of inferior gradually grade of hot-zone to cold-zone; The material of low-temperature receiver face is the cold-zone heat-insulation layer, and it is made up of the conventional ceramic fibrage.And the use occasion of insulation material has thermograde, i.e. the hierarchical structure that reduces gradually of temperature from hot side to huyashi-chuuka (cold chinese-style noodles); This structure meets principle, therefore has more reasonability, economy, and particularly in the insulation construction that some are not suitable for separating, this integrated composite fibre structure has remarkable advantages.It is rational in infrastructure, use is reliable, energy-conservation, be applicable to fields such as industrial furnace, experimental furnace.

The specific embodiment
As shown in Figure 1, the composite fibre structure of ceramic fibre, comprise hot-zone heat-insulation layer 1, inferior hot-zone heat-insulation layer 2 and cold-zone heat-insulation layer 3 successively, one-body molded formation, each interface interpenetrates, do not have stripping layer phenomenon, its structure is strip, arc shape, cylindric or cubic, is provided with heating 4 in the hot-zone heat-insulation layer 1.Hot-zone heat-insulation layer 1 is the polycrystalline mullite fibre layer; Inferior hot-zone heat-insulation layer 2 is polycrystalline mullite fibre and the compound ceramic fiber layer of 1260 alumina silicate fibres; Cold-zone heat-insulation layer 3 is 1260 alumina silicate fibre layers.
As shown in Figure 2, the composite fibre structure of ceramic fibre comprises hot-zone heat-insulation layer 1, inferior hot-zone heat-insulation layer 2 and cold-zone heat-insulation layer 3 successively, the curved shape of its shape.
As shown in Figure 3, the composite fibre structure of ceramic fibre comprises hot-zone heat-insulation layer 1, inferior hot-zone heat-insulation layer 2 and cold-zone heat-insulation layer 3 successively, and its shape is cylindric.
As shown in Figure 4, the composite fibre structure of ceramic fibre comprises hot-zone heat-insulation layer 1, inferior hot-zone heat-insulation layer 2 and cold-zone heat-insulation layer 3 successively, and its shape is cubic.
During concrete the making, make corresponding mould according to use occasion, on mould, heating 4 pre-reasons are gone into earlier with support, vacuum suction filter hot-zone heat-insulation layer 1 (high-grade ceramic fibrage, this kind adds the ceramic fibre of heating, abbreviate electrothermal module as), or directly adopt vacuum suction filter high-grade ceramic fibrage; Vacuum suction filter time hot-zone heat-insulation layer 2 (ceramic fiber layer of time shelves gradually) again; Vacuum suction filter cold-zone heat-insulation layer 3 (conventional ceramic fibrage) then; Above-mentioned composite fibre layer is one-body molded, and each interface interpenetrates behind the finished product, does not have the stripping layer.
The material of the utility model thermal source face is the hot-zone heat-insulation layer, and it is made up of high-grade ceramic fibrage and heating, or directly is the high-grade ceramic fibrage; Material between thermal source face and the low-temperature receiver face is a time hot-zone heat-insulation layer, and it is by the ceramic fiber layer of inferior gradually grade of hot-zone to cold-zone; The material of low-temperature receiver face is the cold-zone heat-insulation layer, and it is made up of the conventional ceramic fibrage.And the use occasion of insulation material, being one has thermograde, i.e. the hierarchical structure that reduces gradually of temperature from hot side to huyashi-chuuka (cold chinese-style noodles); Said structure meets principle, therefore has more reasonability, economy.Particularly in the insulation construction that some are not suitable for separating, this integrated composite fibre structure has remarkable advantages.It is rational in infrastructure, use is reliable, energy-conservation, be a kind of composite fibre structure that is applicable to the ceramic fibre in industrial furnace, experimental furnace field.
