A kind of polysilicon mid-frequency melting furnace smelting device
Technical field
The utility model relates to the medium frequency induction melting furnace field, particularly a kind of polysilicon mid-frequency melting furnace smelting device.
Background technology
The Physical smelting polycrystalline silicon adopts electric arc furnace smelting more for a long time, and its whole apparatus structure is huge, and equipment cost is high, and current consumption is large, pollutes greatly inconvenient maintenance.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and a kind of polysilicon mid-frequency melting furnace smelting device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of polysilicon mid-frequency melting furnace smelting device, it is characterized in that, comprise body of heater, tilting system, water-cooled cable, capacitor panel, cable, power cabinet and transformer, its mounting means is: described body of heater, tilting system, water-cooled cable, capacitor panel, cable, power cabinet and transformer are in turn connected into a line.
Further, in described body of heater, furnace lining is graphite.
Mid-frequency melting furnace smelting device compact construction for such polysilicon, energy-conserving and environment-protective, less investment, cost is low, and flow process is short, easy to maintenance, has met client's requirement.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1-body of heater, 2-tilting system, 3-water-cooled cable, 4-capacitor panel, 5-cable, 6-power cabinet, 7-transformer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As Fig. 1, the present embodiment be for polysilicon mid-frequency melting furnace smelting device, by body of heater 1, tilting system 2, water-cooled cable 3, capacitor panel 4, cable 5, power cabinet 6 and transformer 7 form, and are in turn connected into a line between them, and the interior furnace lining of body of heater 1 adopts graphite.
Polysilicon is as follows by mid-frequency melting furnace smelting device working process:
Put into the polycrystalline silicon raw material of wanting melting in body of heater 1, power-on 6, electric current of intermediate frequency is by heating cables 5, capacitor panel 4, water-cooled cable 3, be input in body of heater 1 ruhmkorff coil, the magnetic field of generation is by the heating of graphite mandarin orange crucible, and the heat energy of plumbago crucible heats polycrystalline silicon raw material again, when temperature qualified, after melted, tilting system 2 is poured out the solution of having smelted in stove, and whole smelting process completes.
Key point is not magnetic conduction of polysilicon, and by heating graphite, graphite is heated heat is imported to polycrystalline silicon raw material, and polysilicon is melted, and graphite does not pollute polysilicon yet.
Be more than to illustrate of the present utility model, this programme not only is confined in above embodiment, for any change of making under this programme inventive concept, all will fall in the utility model protection domain.
