Abstract
The utility model relates to a rapid feedback silicon fluid overflow monitoring device. The rapid feedback silicone fluid overflow monitoring device comprises a graphite crucible and a quartz crucible, wherein the graphite crucible consists of a graphite crucible side plate and a graphite crucible bottom plate; the quartz crucible is placed inside the graphite crucible; a crucible support block and a metal fuse with a controller are arranged below the graphite crucible bottom plate; a bracket made of a high-temperature-resistant insulation material is attached to the periphery of the crucible support block; and the metal fuse is fixed to the bracket made of the high-temperature-resistant insulation material. In the rapid feedback silicone fluid overflow monitoring device, when polysilicon is ingoted and when the overflow of silicon fluid caused by the cracking of the quartz crucible is caused, the overflow can be discovered in time and an ingot furnace is quenched, so that security risks caused by the leakage of silicon can be avoided to the maximum.
Description
Technical field
The utility model relates to the solar battery casting ingot technical field, the quick feedback silicon hydrorrhea flow monitoring device that uses in especially a kind of ingot furnace.
Background technology
In the photovoltaic field, utilizing the method production polycrystal silicon ingot of directional freeze is the method that generally adopts, and its ultimate principle is: polycrystalline silicon raw material is placed in the quartz ceramic crucible, is placed in the specific thermal field system, be heated to fully and melt; Bottom from crucible begins to cool down then, and silicon solution begins crystallization in crucible bottom, gradually upwards growth (solidifying); After accomplishing process of growth.Easy deformation during quartz crucible high temperature is made plumbago crucible and is supported so generally outside quartz crucible, use built-up type graphite backplate, fix with the graphite bolt between the graphite backplate, so joint all has the slit.Since quartz crucible possibly exist naked eyes and instrument can't detected defective, may become focal point of stress during high temperature and cause and break, cause Lou silicon incident; Silicon liquid can flow out from the graphite cake slit;,, flow to and place the placing on the Metal Melting fracture of wire on the resistance hot material of whole bottom of furnace body toward dirty along the crucible back-up block through the base plate pod apertures of heat insulating cage; Wire fusing then produces silicon hydrorrhea stream and reports to the police.And in this process, the mobile overall distance is about 55cm from top to bottom for silicon liquid, and silicon liquid is by way of back-up block, end warming plate; Flow process is uncontrollable; Probably can produce a large amount of overflows and just drop on fusible link, and the Metal Melting circuit wire position that is laid on bottom of furnace body exists in deviation or the life-time service displacement in time to find, can not guarantee that silicon liquid accurately and timely drops on the fusible link; When silicon liquid is assembled in a large number; Burn through furnace bottom very likely, as run into the water-cooled pipeline, then a large amount of gathering of water vapour is prone to cause security incident.This also is the problem that the polycrystalline furnace user relatively pays close attention to; Also there are some patents to leak silicon danger and done research in minimizing; Like the patent No. 200710070536,200810202819,200710070537,200920029606,200720113619; Effusive silicon liquid is carried out water conservancy diversion, accepts and takes sfgd. at furnace bottom; Really played to a certain extent and reduced the effect of leaking the silicon risk, but all be the remedial measures after producing a large amount of overflows, thereby can not in time find to avoid to the full extent this type of risk.
The utility model content
The technical problem that the utility model will solve is: provide a kind of and produce when polycrystalline silicon ingot casting that quartz crucible breaks and when causing silicon hydrorrhea stream; Can in time find and let the ingot furnace chilling, thereby avoid to the full extent because of leaking the monitoring device of the security risk that silicon produces.
The utility model solves the technical scheme that its technical problem adopted: a kind of quick feedback silicon hydrorrhea flow monitoring device; Comprise the plumbago crucible that constitutes by plumbago crucible side plate and plumbago crucible base plate and be placed on the inboard quartz crucible of plumbago crucible; Described plumbago crucible floor below is provided with the Metal Melting fracture of wire of crucible back-up block and tape-controller; With the high-temperature insulation material support, described Metal Melting fracture of wire is fixed on the high-temperature insulation material support around the described crucible back-up block.
The high-temperature insulation material support can be quartz, silicon nitride or refractory ceramics etc.; The Metal Melting fracture of wire can be refractory metal or alloy; Normal working temperature reaches more than 1500 ℃, like silicon-base alloy, tungsten-bast alloy, titanium base alloy, nickel-base alloy, molybdenum base alloy etc., but is not limited to above kind; As long as can satisfy secular high-temperature work environment, can be corroded fusing by silicon liquid again.
Graphite and silicon all conduct electricity under the high temperature, for fear of forming the loop, need the support of high-temperature insulation material as support fixing metal fusible link, and the selection of fusible link also have requirement, can be under 1500 ℃ of high temperature can life-time service, can be corroded by silicon liquid again and fuse.Like the silicon tungstenalloy, select the silicon tungstenalloy of certain alloy ratio, just can guarantee ability life-time service under the high temperature, corroded fusing by silicon liquid easily again.1534 ℃ of the fusing points of iron; It is passable to adopt traditional mode to be placed on furnace bottom, and the temperature low owing to stove is lower, does not have endurance issues; As be placed near the crucible back-up block then not all right; Can't life-time service, because back-up block is in the high temperature more than 1000 ℃ for a long time, and can reach more than 1400 ℃ when changing material.The Metal Melting fracture of wire also can pass through suitable adjustment and be fixed on the plumbago crucible base plate except being fixed on the crucible back-up block.
The beneficial effect of the utility model is to have solved the defective that exists in the background technology, when producing silicon hydrorrhea stream; Because back-up block is located in the crucible bottom, silicon liquid at first will flow on the Metal Melting fracture of wire, and fusible link is corroded fusing by high temperature silicon liquid; No longer constitute the loop and then produce warning, when a small amount of overflow of silicon liquid, just can come to light like this, can feed back and cool off body of heater rapidly; Effectively avoided the generation of a large amount of silicon hydrorrhea stream situation, made the ingot casting process eliminate potential safety hazard.
