Background technique
Single crystal growing furnace is the crystal pulling apparatus of monocrystalline silicon needed for producing solar battery, and the inventory of single crystal growing furnace is confined to single crystal growing furnace
Thermal field size is improving charged material weight while increasing thermal field size in monocrystalline production process, since crucible size is fixed
, while pot life is gradually increased, and to improve inventory, is realized by the way of secondary charging initially feed intake at present
It maximizes, produces at the same time and raw material is still carried out using secondary charging mode after a monocrystal rod throw again, to improve quartz
Crucible utilization rate saves crucible cost.Single crystal growing furnace secondary charging technology is silica crucible residual body when being converted using silicon material solid-liquid
Long-pending variation is realized in the silica crucible of single crystal growing furnace using secondary charging device by the opening and closing of reprint isolating valve and fills with molten silicon
The technology of material.Traditional quartz cone is small with sole piece contact area, and pyroprocess causes to damage to quartz cone during charging, shortens
Quartzy cone service life.
Utility model content
The purpose of this utility model is to provide a kind of metal bottom block assemblies of single crystal growing furnace secondary charging, to solve above-mentioned back
The metal sole piece of the quartz cone bottom proposed in scape technology bores the lesser problem of protected area to quartz.
To achieve the above object, the utility model provides the following technical solutions: a kind of metal bottom of single crystal growing furnace secondary charging
Block assembly, including quartz ampoule, the quartz ampoule lateral wall are welded with chuck, and the chuck is circular configuration, the quartz
Tube cavity bottom is equipped with quartz cone, and the quartz cone is contacted with quartz ampoule inner sidewall, and the quartz cone top part is provided with through-hole, described
Quartzy cone top part is plugged with pull rod by through-hole, and the pull rod top is equipped with connection ring by bolt, and the quartz cone passes through
Pull rod is slidably connected with quartz ampoule inner sidewall, and the connection ring lateral wall is connected with wirerope, quartz cone bottom by solderless wrapped connection
Portion is provided with concave groove, and quartz cone bottom is inlaid with metal sole piece by concave groove.
Preferably, the metal sole piece is iron block.
Preferably, the quartz ampoule is circular configuration.
Preferably, the pull rod bottom passes through contacts at the top of quartz cone and metal sole piece.
Compared with prior art, the utility model has the beneficial effects that the metal bottom block assembly of the single crystal growing furnace secondary charging
Setting, it is reasonable in design, change quartz cone bottom design, by quartz cone bottom metal sole piece size increased to by 50mm
170mm, metal sole piece category heat-resisting material, the condition of high temperature will not cause to damage to metal sole piece；The design increases metal bottom
Block reduces quartz cone and raw material contact area to the protected area of quartz cone.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: quartz ampoule -1, chuck -2, pull rod -3, quartz cone -4, metal sole piece -5, connection ring -6, wirerope -7.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides the following technical solutions: a kind of metal bottom of single crystal growing furnace secondary charging is packaged
It sets, including quartz ampoule 1,1 lateral wall of quartz ampoule is welded with chuck 2, and the chuck 2 is circular configuration, the quartz
1 intracavity bottom of pipe is equipped with quartz cone 4, and the quartz cone 4 is contacted with 1 inner sidewall of quartz ampoule, and 4 top of quartz cone is provided with logical
Hole, 4 top of quartz cone is plugged with pull rod 3 by through-hole, is equipped with connection ring 6 by bolt at the top of the pull rod 3, described
Quartz cone 4 is slidably connected by pull rod 3 and 1 inner sidewall of quartz ampoule, and 6 lateral wall of connection ring is connected with wirerope by solderless wrapped connection
7,4 bottoms of the quartz cone are provided with concave groove, and 4 bottoms of the quartz cone are inlaid with metal sole piece 5 by concave groove.
Wherein, the metal sole piece 5 is iron block.The quartz ampoule 1 is circular configuration.3 bottom of pull rod passes through quartz
Cone 4 with contacted at the top of metal sole piece 5.
Quartz cone: first 4 being installed into 1 inner cavity of quartz ampoule by working principle, and by wirerope 7 to the position of pull rod 3 into
The fixed intracavity bottom to which quartz cone 4 to be fixed on to quartz ampoule 1 of row, then loads raw material into the inner cavity of quartz ampoule 1, will
