Description
Technical field
The present invention relates to the overflowing protective structure in a kind of polycrystalline silicon ingot or purifying furnace, more particularly to a kind of liquid silicon material of working as is from earthenware
The overflow isolating device that can be isolated after being overflowed in crucible in polycrystalline silicon ingot or purifying furnace by effective and safe, to prevent liquid-state silicon contacting metal
Behind furnace wall, explosion accident occurs for ingot furnace.
Background technology
At present, polycrystalline silicon ingot casting is produced using ceramic silica crucible, and silicon material first is put into ceramic quartzy earthenware
In crucible, then ceramic silica crucible is put into polycrystalline silicon ingot or purifying furnace, melting silicon materials are made by heating.Knocking in carrying and feeding
Touch, the inside of ceramic silica crucible can be made to produce hidden slight crack, these hidden slight cracks are not found usually.In polycrystalline silicon ingot casting mistake
Cheng Zhong, ceramic silica crucible have contained high-temperature liquid state silicon material, if the inside of silica crucible there are during hidden slight crack, the high temperature of fusing
Liquid silicon material will flow out ceramic silica crucible from hidden slight crack, can quickly since liquid silicon material has preferable mobility
Flow to ingot casting bottom of furnace body.Since ingot casting furnace body is double layer jacket structure, cooling water is connected with chuck, and bottom of furnace body is deposited
In weld seam interface, after the high-temperature liquid state silicon material of overflow is contacted with the furnace wall of low temperature, bottom of furnace body weld seam joint broken can be caused, pressed from both sides
Cooling water in set will be flowed into ingot furnace body, and the cooling water of inflow makes furnace pressure wink by the silicon liquid instant vaporization of high temperature
Between huge increasing, cause ingot furnace to explode.Further, since a workshop is often provided with tens ingot furnaces, when there is ingot furnace
During problem, in order to ensure safety, all ingot furnaces of regulatory requirements have to enter into pole cold state, can cause great economic loss.
The content of the invention
The present invention provides a kind of overflow isolating device of polycrystalline silicon ingot or purifying furnace, solves polycrystalline silicon ingot or purifying furnace high temperature and overflows
