Technical field
The present invention relates to the overflowing protective structure in a kind of polycrystalline silicon ingot or purifying furnace, particularly to one when liquid-state silicon material is from earthenware
The overflow isolating device can isolated by effective and safe after overflowing in polycrystalline silicon ingot or purifying furnace in crucible, to prevent liquid-state silicon contacting metal
Behind furnace wall, ingot furnace generation explosion accident.
Background technology
At present, polycrystalline silicon ingot casting uses pottery silica crucible to produce, and silicon material is first put into pottery quartz earthenware
In crucible, then pottery silica crucible is put in polycrystalline silicon ingot or purifying furnace, make melting silicon materials by heating.Knocking in carrying and charging
Touching, the inside of pottery silica crucible can be made to produce hidden slight crack, these hidden slight cracks are not found.In polycrystalline silicon ingot casting mistake
Cheng Zhong, pottery silica crucible has contained high-temperature liquid state silicon material, if the inside of silica crucible exists hidden slight crack, the high temperature of fusing
Liquid-state silicon material will flow out pottery silica crucible from hidden slight crack, owing to liquid-state silicon material has preferable mobility, and can quickly
Flow to ingot casting bottom of furnace body.Owing to ingot casting body of heater is double layer jacket structure, chuck is connected with cooling water, and bottom of furnace body is deposited
At weld seam interface, after the high-temperature liquid state silicon material of overflow contacts with the furnace wall of low temperature, bottom of furnace body weld seam joint broken can be caused, folder
Cooling water in set will flow in ingot furnace body, and the cooling water of inflow, by the silicon liquid instant vaporization of high temperature, makes furnace pressure wink
Between huge increasing, cause ingot furnace to explode.Additionally, due to a workshop is often provided with tens ingot furnaces, occur when there being 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.
Summary of the invention
The invention provides the overflow isolating device of a kind of polycrystalline silicon ingot or purifying furnace, solve high temperature in polycrystalline silicon ingot or purifying furnace and overflow
