Specifically, the terminal box end of the thermocouple is fixed on ingot casting furnace body outer bottom, the temperature-sensitive member of the thermocouple
Part end passes through heat exchange platform, close to Graphite platform.
The beneficial effects of the utility model are：When silicon liquid overflow but unblown overflow silk or do not trigger alarm and cause to heat
Device cannot disconnect lasting heating automatically, can be set by being used to measure the thermocouple monitoring of temperature in heat-insulation cage by switch board
Determine alarm temperature, start alarm during more than set temperature, be the guarantee for preventing the monitoring property for causing safety accident.Together
When, when flooded conditions occur, the overflow cotton structure more than can effectively prevent silicon material to flow into bottom in polycrystalline ingot furnace stove,
Polycrystalline ingot furnace is damaged, loss is preferably minimized.
Based on the above technical solution, the utility model has also done following improvement：
To prevent TC1 thermocouple temperature measurement misalignments, maximum power is caused to alarm, actual temperature superhigh temperature in stove, there are superelevation
Warm security risk resets control program on switch board, and using power control mode, control actual power output is more pacified
Entirely, the accidents such as overflow are prevented.
Further, it is provided on the fixed containing box in ingot casting furnace body bottom side and measures ingot furnace body bottom portion surface temperature
Thermometric detector, contacted with probe with furnace body outer surface and detect furnace body outer bottom face temperature, thermometric detector and switch board
Connection.
Advantageous effect using above-mentioned further scheme is：By detecting lower furnace body outer bottom temperature, set on switch board
The alarm temperature of location survey temperature detector when more than alarm temperature, starts alarm, and control output power and the progress of ingot furnace
The corresponding operating of next step timely and effectively ensures the personal safety of operating personnel and damage polycrystalline ingot furnace, loss is dropped to
It is minimum.
