Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of fritting formula crucible heating device, can effectively heat higher boiling (boiling temperature reaches more than 2000 ℃) material, meet its demand for heat, device for simultaneous heating is simple in structure, cost is low, has effectively extended the service life of crucible in heating process.
To achieve these goals, a kind of fritting formula crucible heating device that the utility model adopts, comprises water cooling box, heat-insulation layer, crucible layer, and described water cooling box inside is provided with cooling bath, is also filled with heat-insulation layer in water cooling box, is placed with crucible layer on heat-insulation layer.
Further, described crucible layer comprises that quantity is no less than two-layer crucible.
Further, in described crucible layer, the material of adjacent two layers crucible is identical or different.
Further, described cooling bath is made up of two-layer stainless steel.
Further, described heat-insulation layer is made up of graphite felt.
Compared with prior art, the beneficial effects of the utility model are:
(1) fritting formula crucible heating device can meet the heat request that adds of different molten boiling point materials, heating object in crucible layer is divided into boiling section, fusion zone and solidification zone, be that heating object in crucible layer exists obvious thermograde and two physics phase points, be boiling point and fusing point junctional area, be that 2000 ℃ of molten boiling point materials of above height can effectively heat to temperature range, fusing, boiling, the PROCESS FOR TREATMENT such as volatilization, do not need to use other complex structures, firing equipment that cost is high to complete.
(2) while using fritting formula crucible heating device to heat material, do not need in crucible, to add other materials, crucible does not contact with the liquid phase of heating object, and has lower thermograde region,, with heating object generation physics and chemical reaction, effectively do not avoid the pollution of product.
(3), while use, can by the crucible of same multi-layer phase material, multilayer unlike material separately or be used in conjunction with, effectively raise crucible serviceability; In the time that the material of crucible in the crucible layer using is not identical, outer crucible can effectively reduce the thermal loss of inner crucible, puies forward high-octane utilization rate, improves the efficiency of heating surface.
(4) by passing into cooling water in the cooling bath in water cooling box, to crucible effective temperature-reducing, guarantee that crucible is in its temperature resistant range, and can Yin Gaowen or contact and cause that physics or chemical reaction cause the consumption to crucible with material-to-be-heated liquid phase, the service life of crucible extended.

Fig. 1 is structural representation of the present utility model.
In figure: 1, water cooling box, 1.1, cooling bath, 2, heat-insulation layer, 3, crucible layer, 4, heating source, 5, boiling section, 6, melting zone, 7, solidification zone.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of fritting formula crucible heating device, comprises water cooling box 1, heat-insulation layer 2, crucible layer 3, and described water cooling box 1 inside is provided with cooling bath 1.1, is also filled with heat-insulation layer 2 in water cooling box 1, is placed with crucible layer 3 on heat-insulation layer 2.
As further improvement of the utility model, described crucible layer 3 comprises that quantity is no less than two-layer crucible, the identical or different crucible serviceability that all can effectively improve of material of adjacent two layers crucible; In the time that the material of crucible in the crucible layer 3 using is not identical, outer crucible can effectively reduce the thermal loss of inner crucible, puies forward high-octane utilization rate, improves the efficiency of heating surface.
As further improvement of the utility model, cooling bath 1.1 is made up of two-layer stainless steel, and obturation effect is good, effectively carries out cooling to the outer crucible near cooling bath 1.1 in crucible layer 3.
As further improvement of the utility model, heat-insulation layer 2 is made up of graphite felt, high insulating effect.
Embodiment mono-
Use heating plasma evaporative cooling physical vapor method to heat, first the identical or different crucible composition crucible layer 3 of the material of selected suitable quantity.As being that the metal tantalum of 5425 ℃ is while heating to boiling point, first select the tantalum ingot that is applicable to dimensional requirement as internal layer heating object, then be coated the graphite crucible of corresponding size in tantalum ingot outside, outside crucible layer 3 and between cooling bath 1.1, graphite felt is installed as heat-insulation layer 2, opening heating source 4 heats, after a period of time, the material in inner crucible is divided into 7 three layers of boiling sections 5, melting zone 6, solidification zone, collects metallic vapour as required from boiling section 5.In heating process, to in cooling bath 1.1, pass into cooling water, effectively external crucible is lowered the temperature, guarantee in thermograde region that crucible layer 3 is present in lower than heating object fusing point (lower than 2996 ℃ of the fusing points of tantalum), prevent that crucible self from melting or with tantalum generation physics or chemical reaction, thereby extended service life of crucible.
