Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the energy-conservation polycrystalline silicon ingot or purifying furnace of a kind of band heating cabinet, comprises body of heater 1, well heater 2, insulation top board 4 and Thermal insulation cage body 5; Well heater 2 is fixed on insulation top board 4, and Thermal insulation cage body 5 is arranged in body of heater 1, and Thermal insulation cage body 5 tops are provided with insulation top board 4, and Thermal insulation cage body 5 bottoms are provided with the insulation base plate 8 with pillar 10; Also comprise heating cabinet 12, heating cabinet 12 is fixed on body of heater 1 inside, and Thermal insulation cage body 5 is connected with heating cabinet 12, and insulation top board 4, Thermal insulation cage body 5, insulation base plate 8 form the thermal field cavity of a sealing.
The top of pillar 10 is provided with heat exchange platform 9, and heat exchange platform 9 tops are provided with crucible 7.
Also comprise insulating ring bar 11, be arranged between well heater 2 and heat exchange platform 9, insulating ring bar 11 is fixedly connected with insulation top board 4 by connecting strip 3.
During normal production, heating cabinet 12 heats, polycrystalline silicon raw material 8 is heated fusing in crucible 7, when entering the long brilliant stage, Thermal insulation cage body 5 is slowly mentioned, heat exchange platform 9 is exposed in the bottom of Thermal insulation cage body 5, a large amount of thermal radiation meetings is distributed toward body of heater 1 chamber from the bottom of Thermal insulation cage body 5 by two side directions via heat exchange platform 9, the bottom of polycrystalline silicon raw material 8 is cooled, start long brilliant, but part polycrystalline silicon raw material 8 above also must remain on liquid state for a long time, now, buffer action due to insulating ring bar 11, limited distributing of polycrystalline silicon raw material 8 top heats, alleviated the power consumption time of well heater 2, simultaneously, buffer action due to insulating ring bar 11, also increased the upper and lower two-part temperature head of the interior thermal field of Thermal insulation cage body 5, make the modified line of silicon liquid phase more obvious, thereby grow more preferably crystal.
