Embodiment 1
[0043] In view of the above problems, this embodiment provides a crystalline silicon ingot furnace provided with an overflow protection device for silicon liquid, including:
[0044] Furnace body
[0045] A crucible arranged in the furnace body, the crucible is preferably a quartz crucible, and is used for containing silicon material;
[0046] The crucible bottom plate is located below the bottom of the crucible. The crucible bottom plate is provided with a plurality of diversion holes penetrating the crucible bottom plate. When the crucible accidentally ruptures and causes the silicon liquid to overflow, the overflowing silicon liquid is removed from the crucible The bottom part passes through the bottom plate of the crucible through the orifice provided on the bottom plate of the crucible;
[0047] A cooling block located under the crucible bottom plate, the cooling block is provided with at least one flow guide groove;
[0048] A flow guide tube arranged under the cooling block, the...
