Abstract
The utility model relates to a feeder, in particular to a proportioner that is specifically used for supplementary feed of a directional solidification polysilicon casting furnace. The proportioner comprises a feed inlet, a discharge outlet and a feed barrel, wherein the feed inlet is communicated with the discharge outlet through the feed barrel. The proportioner can control the speed of the supplementary feed at a certain proper numerical value and the feeder is simple in structure, easy for processing and manufacturing, not likely to block materials and convenient for operation.
Description
Technical field
The utility model relates to a kind of material feeder, and particularly a kind of proportioner specifically is applied to directional freeze polysilicon foundry furnace and replenishes reinforced.
Background technology
Directional freeze polysilicon foundry furnace replenish reinforced in, material feeder is that control silicon material adds the intravital speed of directional freeze polysilicon foundry furnace, if it is too fast to replenish reinforced speed, then can cause the silicon liquid of the intravital molten state of relatively large directional freeze polysilicon foundry furnace to splash out, cause security incident; It is too slow to replenish reinforced speed, and additional reinforced efficient is low, the time is long.So seek a kind of proportioner, can be necessary with replenishing reinforced speed control in certain appropriate value.
Summary of the invention
The purpose of this utility model is to be provided for directional freeze polysilicon foundry furnace and replenishes reinforced material feeder, can will replenish reinforced speed control in certain appropriate value, and this material feeder is simple in structure, and processing and manufacturing easily is difficult for getting stuck, and is convenient to operation.
The technical solution of the utility model is:
Be used for directional freeze polysilicon foundry furnace and replenish reinforced proportioner, comprise opening for feed, discharge port, barrel, wherein: opening for feed is communicated with discharge port by barrel.
The angle that opening for feed is connected with the barrel wall is at 30 degree-45 degree.
Be used for directional freeze polysilicon foundry furnace and replenish reinforced proportioner, wherein: be provided with impeller and rotating shaft in the barrel, the rotating shaft impeller is rotated, and opening for feed is communicated with discharge port by the impeller that rotates.
Rotating shaft is controlled rotating speed by being connected with speed reduction unit, motor, variable-frequence governor.
Be used for directional freeze polysilicon foundry furnace and replenish reinforced proportioner, wherein: barrel is provided with the barrel lid.
In order to prevent that the outlet beyond the discharge port from barrel of silicon material from spilling, so be provided with the barrel lid, plays sealing function.
Be used for directional freeze polysilicon foundry furnace and replenish reinforced proportioner, wherein: be enclosed with the soft lip of one deck on the outside surface of impeller, the material of soft lip is a rubber, because the material of barrel wall is harder, in the process of feed, the bigger silicon material of particle diameter is in rotation process, easy and hard barrel wall acts on mutually, cause the phenomenon that gets stuck, by on the outside surface of impeller, being enclosed with the soft lip that one deck rubber is made, in silicon material rotation process, played shock absorption, thus the generation of the phenomenon that prevented to get stuck.
Advantage of the present utility model: can will replenish reinforced speed control in certain appropriate value, and this material feeder is simple in structure, processing and manufacturing easily is difficult for getting stuck, and is convenient to operation.
