Abstract
The utility model relates to the technical field of polycrystalline furnaces, in particular to a polycrystalline furnace with a detective device for preventing accidental fire striking, which comprises a furnace body. The furnace body is provided with a thermal insulation cage with a hanging rod, a thermal insulation top plate is arranged on the upper portion of the thermal insulation cage, and a heater which is arranged below the thermal insulation top plate in hanging mode through bolts and nuts are arranged in the thermal insulation cage. A ceramic pad is arranged on each nut to match with the nut, and a graphite paper layer is covered on the upper surface of the ceramic pad. The nut sequentially penetrates through the graphite paper layer and the ceramic pad to be installed at the top of the heater. By means of the graphite paper layer covered on the ceramic pad arranged on the nut which is arranged at the top of the heater in hanging mode, the polycrystalline furnace with the detective device for preventing the accidental fire striking prevents carbon powder from falling in the ceramic pads, enables the heater to be communicated with a thermal insulation carbon felt, resolves the technical problem of lower resistance, reduces fire striking accidents, and improves safety performance.
Description
Technical field
The utility model relates to the polycrystalline furnace technical field, relates in particular to a kind of polycrystalline furnace that prevents unexpected sparking protector that has.
Background technology
Solar cell industry is one of industry with fastest developing speed in recent years, over nearest 5 years to surpass 40% speed rapid growth.In various types of solar cells, crystal-silicon solar cell is because its efficiency of conversion is high, and technology maturation and continue to hold the lead has occupied the share more than 90%.
Polycrystalline furnace is a kind of silicon remelting device, is used to produce a large amount of qualified solar-grade polysilicons.To reach polysilicon that certain purity requires in the production and pack in the stove, come out of the stove by processing requirement heating and melting, directional long crystal, thermal treatment, cooling, and the long brilliant such core environment of polysilicon remelting, we are referred to as thermal field.
Existing polycrystalline furnace, the ceramic blanket on the well heater top lifting nut often falls into the carbon dust that top board weares and teares; Well heater is communicated with heat preservation carbon felt; Cause resistance on the low side, also can cause the sparking accident when serious, bring very big potential safety hazard for the staff of factory.
The utility model content
The technical problem that the utility model will solve is: in order to improve the safety performance of thermal field of single crystal furnace, the utility model provides a kind of polycrystalline furnace that prevents unexpected sparking protector that has.
The utility model solves the technical scheme that its technical problem adopted: a kind of have a polycrystalline furnace that prevents unexpected sparking protector; Comprise body of heater; Body of heater is provided with GRD geared heat insulating cage; The top of heat insulating cage is provided with the heat insulating top board, is provided with the well heater that is lifted on heat insulating top board below through screw bolt and nut in the described heat insulating cage, cooperates on the described nut ceramic blanket is installed; The upper surface of described ceramic blanket is equipped with the graphite ply of paper, and described nut passes the top that graphite ply of paper and ceramic blanket are installed in well heater successively.
The beneficial effect of the utility model is; The polycrystalline furnace that prevents unexpected sparking protector that has of the utility model is laid graphite linings through lifting on the ceramic blanket on the nut at the well heater top; Avoid carbon dust to fall into ceramic gasket, well heater is communicated with heat preservation carbon felt, caused resistance technical problem on the low side; Reduce the generation that causes the sparking accident, improved the safety performance of polycrystalline furnace thermal field.
