Abstract
The invention discloses a refining and purifying system of an ingot furnace, and the system comprises a servo motor, a lead screw, a bearing, a connecting device, an air flue, a cover plate and a crucible, wherein the servo motor is connected with the lead screw, the bearing is arranged on the lead screw, one end of the connecting device is connected with the bearing, the other end of the connecting device is connected with the air flue, the cover plate is hung at the lower end of the air flue, and the air flue can drive the cover plate to move up and down in the crucible. According to the invention, an argon pipeline and a top cover plate fall along with the descending of a liquid level, so that argon is fully utilized, and impurities are taken away while being pumped away by virtue of a vacuum pump; the content of impurities in a silicon solution is reduced, the product quality is improved; and argon is fully utilized, and the usage amount of argon is reduced.
Description
Technical field
The present invention is a polycrystalline silicon ingot or purifying furnace refining purification system in the solar cell.
Background technology
The argon gas inlet mouth is a fixed, irremovable during the work of present ingot furnace, cover plate also be fixedly stubbornly refuse mobile.The purpose of logical argon gas is to improve the gas circulation of ingot furnace during ingot furnace work, reduces impurity and gets into silicon feed liquid body, guarantees the purity of silicon.Yet liquid level descends in the silicon material melting process, and it is big that the gap between liquid level and the cover plate becomes, argon stream direction generation dynamic change, and cause impurity to get into silicon liquid.As shown in Figure 2.
Summary of the invention
Goal of the invention: to the problem and shortage of above-mentioned prior art existence; The purpose of this invention is to provide a kind of ingot furnace refining purification system; Make argon gas pipeline and top blind flange follow decline, thereby argon gas is fully used, and keep the air flow line of argon gas along with liquid level descends; Reduce impurity and get into silicon liquid, thereby improve product quality; Argon gas is fully used, reduces the usage quantity of argon gas.
Technical scheme: for realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of ingot furnace refining purification system, comprises servomotor, screw mandrel, bearing, coupling device, air flue, cover plate and crucible; Wherein servomotor connects screw mandrel; Bearing is installed on the screw mandrel, an end connection bearing of coupling device, and the other end connects air flue; Said cover plate hangs over the lower end of air flue, and air flue can drive cover plate and in crucible, move up and down.
Preferably, also comprise keyway, said servomotor is connected with screw mandrel through keyway.
Preferably, said coupling device is a web plate.
Preferably, an end of said coupling device is connected with the bearing level.
Preferably, the other end of said coupling device is connected up and down with air flue.
Preferably, an end of said coupling device is connected with the bearing level through bolt.
Preferably, the other end of said coupling device is connected up and down with air flue through bolt or suspension ring.
Beneficial effect: the present invention makes argon gas pipeline (i.e. " air flue ") follow decline along with silicon feed liquid face descends; Argon gas is fully used, and keeps the air flow line of argon gas, reduce impurity and get into silicon liquid; Thereby the raising product quality reduces because the defect problem that impurity causes; The utilization ratio of argon gas is improved, reduce the usage quantity of argon gas.

Fig. 3 is the air-flow synoptic diagram of ingot furnace refining purification system of the present invention.
Among the figure, 1 servomotor, 2 screw mandrels, 3 bearings, 4 web plates, 5 air flues, 6 cover plates, 7 crucibles, 8 melted silicons, 9 liquid levels.Arrow among Fig. 2 and Fig. 3 shows the direction of air-flow.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, servomotor 1 is connected with screw mandrel 2 through keyway (not shown), and bearing 3 is installed on the screw mandrel 2; Web plate 4 is connected with bearing 3 levels through first bolt (not shown); Web plate 4 is connected up and down with air flue 5 usefulness, second bolts (not shown) or suspension ring (not shown), and cover plate 6 hangs over the lower end of air flue 5, and the silicon material is contained in the crucible 7; The silicon material at high temperature is fused into melted silicon 8; Servomotor 1 moves up and down bearing 3 through rotating band movable wire bar 2 rotations of self, and move up and down drive web plate 4, air flue 5 and the cover plate 6 of bearing 3 move up and down.
As shown in Figure 2, when ingot furnace was started working, argon gas blew out from the lower end from the upper end air inlet of air flue 5.The fusing of silicon material, the liquid level 9 of melted silicon 8 descends PLC (Programmable Logic Controller; Programmable logic controller) (not shown) control servomotor 1 running; Air flue 5 descends with cover plate 6, guarantees the clearance constant of cover plate 6 to liquid level 9, simultaneously the air outlet of air flue 5 and the clearance constant of liquid level 9; Air flow line is constant, reduces foreign gas and gets into silicon liquid.
