Technical field
The present invention relates to a kind of feeding device, more particularly to a kind of quartzy casing drum that charging is repeated for single crystal growing furnace.
Background technology
Single crystal growing furnace is the process units for producing monocrystalline silicon used in solar battery sheet.Its operating process is：Feed, take out
Sky, melt, seeding, shouldering, isometrical, ending, blowing out；Its production process is under vacuum argon gas, is filled in quartz crucible solid
After state silicon raw material, melt silicon material by heating, by the tension force between the rotation of seed crystal and liquid, and be lifted up to manufacture
Monocrystalline.At present, crystal pulling substantially uses disposable feed way, i.e., before heating disposably toward quartzy earthenware collapse in fill it up with silicon
Material, due to the shape of silicon material, not of uniform size, significant portion of space can be caused when silicon material is held in quartz crucible, so as to not
The useful space of quartz crucible can be made full use of.In addition, quartzy earthenware snail top there remains larger sky after the thawing of solid-state silicon
Between, because liquid silicon is bigger than solid silicon density.Therefore, based on above two reason, after silicon material is melted completely on quartzy earthenware snail
Still there is ample space side, and quartzy earthenware evidence is underutilized.However, single only quartzy earthenware is few according to the monocrystalline amount of pull-out, and
For quartzy earthenware according to using once scrapping afterwards, it accounts for significant proportion in monocrystalline production cost, produces production cost height and produces
The low phenomenon of efficiency.Though in addition, there is the secondary charging that part producer has been achieved with single crystal growing furnace at present, due to secondary charging device
Mostly external device (ED) or container type device, are not only limited by raw material size, can not directly use piece bulk silicon material (solar energy
Monocrystalline edge skin material is a kind of piece bulk silicon material), and exist capsule contamination, charging during easily block, feeding device cost compared with
The defects of high.A kind of therefore, it is proposed that quartzy casing drum that charging is repeated for single crystal growing furnace.
