Description
Technical field
The utility model relates to polycrystalline silicon ingot or purifying furnace attachment technique field.
Background technology
Polycrystalline silicon ingot or purifying furnace is the equipment for casting polycrystalline silicon ingot, it is after silicon material high-temperature fusion, to pass through directional freeze condensation-crystallization, make it form the consistent silicon ingot in crystal orientation, in its production process, the control of furnace temperature plays conclusive effect, and polycrystalline silicon ingot or purifying furnace furnace temperature is measured by thermopair.Thermopair is made up of major portions such as thermode, insulation covering protective tube and terminal boxes conventionally; because often one section of thermopair is inserted in burner hearth and is measured; and furnace chamber temperature is up to more than 1600 degree; the residing environment of thermopair is very severe; under the erosion of obnoxious flavour; often there is oxidation and be corroded, therefore need to be in the outside of temperature element sheathed a set of protector, to extend the work-ing life of thermopair.
The thermopair model that polycrystalline silicon ingot or purifying furnace is used at present adopts R type, and R type thermopair is noble-metal thermocouple, because of precious metal material costliness, so disposable investment is larger.Because the structure of thermopair is all to weld together between positive and negative electrode, and exposed outside secondary protection tube (as Fig. 2), in the time dismantling or move, very easily collide with exposed thermo wires and solder joint, cause between thermo wires and solder joint and disconnect, thermopair is scrapped, caused the maintenance cost of equipment higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, safe and reliable, polycrystalline silicon ingot or purifying furnace thermocouple assembly that can effectively increase the service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of polycrystalline silicon ingot or purifying furnace thermocouple assembly, comprise thermocouple wire, internal layer pillar and outer pillar, described thermocouple wire is longitudinally installed in internal layer pillar and upper and lower ends is respectively equipped with solder joint, described outer pillar is the right cylinder that upper end is provided with open slot, and described thermocouple wire and top solder joint thereof are placed in open slot.
Preferably, described outer pillar is followed successively by graphite sleeve, zirconium white pillar and aluminum oxide pillar from outside to inside, and described internal layer pillar is arranged on aluminum oxide pillar middle part.
Preferably, described open slot is rectangular aperture groove, and described thermocouple wire place plane is parallel with otch.
The beneficial effect that adopts technique scheme to produce is: by extending the end of the outer pillar of thermopair, and middle part arranges open slot in the top, thermocouple wire and top solder joint thereof are built in open slot, thereby solder joint and exposed thermo wires between thermocouple wire positive and negative electrode are protected, make thermopair in dismounting or moving process, can not make solder joint and exposed thermocouple wire stressed and rupture even if collide with yet, can effectively protect like this thermopair, extend its work-ing life, the graphite sleeve of outer pillar, zirconium white pillar and aluminum oxide pillar all have high fusing point, have high temperature resistant, scale resistance, the advantage of good corrosion resistance.The utlity model has advantage simple in structure, safe and reliable, that can effectively increase the service life, manufacture craft is simple, economy and durability, easy to use, has indirectly reduced cost of equipment maintenance.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of polycrystalline silicon ingot or purifying furnace thermocouple assembly as shown in Figure 1,3, comprise thermocouple wire 2, internal layer pillar 5 and outer pillar 3, described thermocouple wire 2 is longitudinally installed in internal layer pillar 5 and upper and lower ends is respectively equipped with solder joint 1, described outer pillar 3 is provided with the right cylinder of open slot 4 for upper end, described thermocouple wire 2 and top solder joint 1 thereof are placed in open slot 4, described open slot 4 is rectangular aperture groove, and described thermocouple wire 2 place planes are parallel with otch.Rectangular aperture groove is easy to process, and otch is parallel to the plane at thermocouple wire 2 places that are made up of positive and negative electrode, is more conducive to installation and the maintenance of thermocouple wire 2.
Described outer pillar 3 is followed successively by graphite sleeve 8, zirconium white pillar 7 and aluminum oxide pillar 6 from outside to inside, and described internal layer pillar 5 is arranged on aluminum oxide pillar 6 middle parts.Graphite sleeve 8, zirconium white pillar 7 and aluminum oxide pillar 6 all have high fusing point, and high thermal resistance is good, scale resistance is good and good corrosion resistance, are particularly useful for the furnace inner environment of polycrystalline silicon ingot or purifying furnace.
By extending the end of the outer pillar 3 of thermopair, and middle part arranges open slot 4 in the top, thermocouple wire 2 and top solder joint 1 thereof are built in open slot 4, thereby solder joint 1 and exposed thermo wires between thermocouple wire 2 positive and negative electrode are protected, make thermopair in dismounting or moving process, can not make solder joint 1 and exposed thermocouple wire 2 stressed and rupture even if collide with yet, can effectively protect like this thermopair, extend its work-ing life, the graphite sleeve 8 of outer pillar 3, zirconium white pillar 7 and aluminum oxide pillar 6 all have high fusing point, have high temperature resistant, scale resistance, the advantage of good corrosion resistance.The utlity model has advantage simple in structure, safe and reliable, that can effectively increase the service life, manufacture craft is simple, economy and durability, easy to use, has indirectly reduced cost of equipment maintenance, has very strong practicality.
