Abstract
The utility model discloses a single crystal furnace capable of being charged repeatedly. The single crystal furnace comprises a furnace body and a quartz crucible, and further comprises a charging device used to throw materials into the quartz crucible. The single crystal furnace capable of being charged repeatedly has the advantages that in the production process of the single crystal furnace, materials are charged repeatedly into the quartz crucible through the charging device according to collapsing conditions of the materials in the quartz crucible or requirements for drawing length of a silicon single crystal rod so as to increase the amount of thrown materials, improve the utilization rate of the volume of the quartz crucible, and achieve maximization of production to the greatest extent.
Description
Technical field
The utility model relates to a kind of equipment of manufacture order crystal silicon, particularly a kind of single crystal growing furnace that can repeatedly feed in raw material.
Background technology
During present produce single crystal silicon rod, single crystal growing furnace is fed intake by maximum solidification of silicon material charging capacity, the silicon material is after melting fully in the quartz crucible, also just accounted for about 2/3rds of quartz crucible volume, be subjected to single crystal furnace structure and production technique program limit, can't again feed in raw material in the production process, thereby the production equipment system availability is not high, this has also affected the drawing length of silicon single crystal rod.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model provides a kind of single crystal growing furnace that can repeatedly feed in raw material, and improves the utilization ratio of production system, satisfies the needs of silicon single crystal rod drawing length.
Technical scheme: a kind of single crystal growing furnace that can repeatedly feed in raw material, comprise the quartz crucible of body of heater, described body of heater inside also comprising feeding device, in described quartz crucible, feed intake.
Described feeding device comprises feeder hopper, supply disk, filling tube, vibrator, it is outside that described feeding device is positioned at described body of heater, described filling tube passes described body of heater and stretches to described quartz crucible, material in the described feeder hopper falls into described supply disk in the effect of described vibrator, sends into described quartz crucible by described filling tube again.
Beneficial effect: compared with prior art, the utility model has the advantages that in the production process of single crystal growing furnace, according to the collapse drawing length demand of material situation or silicon single crystal rod of material in the quartz crucible, by feeding device to repeatedly reinforced in the quartz crucible, increase charging capacity, improve the capacity utilization of quartz crucible, reach as far as possible and produce maximization.
Description of drawings
Accompanying drawing Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing Fig. 1 and specific embodiment, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
Shown in Figure 1 such as accompanying drawing, a kind of single crystal growing furnace that can repeatedly feed in raw material, the quartz crucible 2, the feeding device that comprise body of heater 1, body of heater 1 inside, feeding device comprises feeder hopper 3, supply disk 4, filling tube 6, vibrator 5, feeding device is positioned at body of heater 1 outside, filling tube 6 passes body of heater 1 and stretches to quartz crucible 2, and the material in the feeder hopper 3 falls into supply disk 4 in the effect of vibrator 5, sends into quartz crucible 2 by filling tube 6 again and feeds intake.
In the production process, after the silicon material in the quartz crucible collapsed material, the volume of quartz crucible was not filled, and can start feeding device this moment, feeds intake.
Claims (2)
1. the single crystal growing furnace that can repeatedly feed in raw material comprises body of heater (1), the inner quartz crucible (2) of described body of heater (1), it is characterized in that: also comprise feeding device, feed intake in described quartz crucible (2).
