Abstract
The utility model relates to a production system for solar silicon bars, which comprises a single crystal furnace, an argon tank and a gas pipeline which communicates the single crystal furnace with the argon tank, and further comprises a nitrogen tank; and a gas distributor is arranged on the gas pipeline, the gas outlet end of the gas distributor is connected with the inner cavity of the signal crystal furnace through a gas outlet pipe, and the two gas inlet ends of the gas distributor are respectively connected with the argon tank and the nitrogen tank through gas inlet pipes. According to the production system for solar silicon bars, a protective gas is replaced by nitrogen during a cooling stage, argon is used as the protective gas during the single crystal growing process, accordingly, double-path gas supply is realized, and the production system for solar silicon bars is easy to operate during the use. According to the production system for solar silicon bars, the cost can be effectively reduced under the condition of ensuring the quality of single crystals.
Description
Technical field
The utility model relates to a kind of production system of sun power silicon rod, is applied to the photovoltaic field.
Background technology
In the production process of sun power silicon rod,, adopt argon gas for a long time as the shielding gas in the single crystal growth process owing to receive the influence of traditional technology always; Argon gas is in dominant position as shielding gas always; Under the requirement because of monocrystalline growing process, colling stages requires to strengthen the consumption of argon gas, so that shorten the decay period; But argon gas is comparatively expensive, makes production cost higher.
The content of utility model
The technical problem to be solved of the utility model provides a kind of production system that satisfies the sun power silicon rod that silicon single crystal rod production can reduce cost again.
The technical scheme that the utility model is taked is: a kind of production system of sun power silicon rod, comprise single crystal growing furnace, argon tanks and the gas piping that is communicated with single crystal growing furnace and argon tanks, and also comprise nitrogen pot; On said gas piping, be provided with gas diverter, the gas output end of gas diverter is through the brilliant furnace chamber of escape pipe order, and two gas input terminuss of gas diverter connect argon tanks and nitrogen pot through inlet pipe respectively.
Wherein, on the inlet pipe between described gas diverter and argon tanks, the nitrogen pot, be respectively arranged with valve switch.
Wherein, described escape pipe is a metallic hose, and described inlet pipe is a stainless steel pipes.
The beneficial effect that the utility model is compared with prior art obtained is:
1, the utility model mainly is that shielding gas changes nitrogen into when realizing colling stages, in the single crystal growth process with argon gas as shielding gas, thereby realization parallel gas feed, in use easy handling.
2, the utility model can effectively reduce cost in the situation that guarantees the monocrystalline quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.A kind of production system of sun power silicon rod comprises single crystal growing furnace 1, argon tanks and the gas piping that is communicated with single crystal growing furnace and argon tanks, also comprises nitrogen pot; On said gas piping, be provided with gas diverter 2, the gas output end of gas diverter connects single crystal growing furnace 1 inner chamber through escape pipe 3, and two gas input terminuss of gas diverter 2 connect argon tanks and nitrogen pot through inlet pipe 4 respectively.Wherein, on the inlet pipe 4 between described gas diverter 2 and argon tanks, the nitrogen pot, be respectively arranged with valve switch 5.Among the embodiment, escape pipe 3 adopts metallic hose, and inlet pipe 4 adopts stainless steel pipes.
During work, non-colling stages uses argon gas as shielding gas, when waiting to get into the crystal pulling colling stages, with the argon gas valve closes, switches to the nitrogen air feed simultaneously, keeps the pressure in the stove constant, is adjusted to normal air feed state after waiting to tear open stove.
