Description

A kind of silicon core furnace masterbatch firm banking

Technical field

The utility model is related to the technical field of polysilicon production of photovoltaic industry, specifically a kind of silicon core furnace masterbatch fixes bottom Seat.

Background technology

As the whole world is to the common recognition of green energy resource, photovoltaic industry is grown rapidly, as upper in photovoltaic industry chain Product is swum, supply falls short of demand for polysilicon, and strong business magnate puts into huge fund intervention polysilicon industry, development rule one after another both at home and abroad Mould is increasing, and silicon core furnace is an important link on production of polysilicon chain, and demand is also increasing.

Silicon core furnace is the equipment of drawing silicon core, and in silicon core furnace, high-frequency current is changed into powerful high frequency by induction coil Magnetic field, processed silicon core masterbatch are heated rapidly under the action of vortex and magnetic hystersis loss, and later, silicon core masterbatch passes through silicon core The upper shift mechanism of stove and the matching operation of lower feeding machanism, the operation completed silicon core and drawn stablized；Pedestal is as silicon core masterbatch With the connector of lower feed axis, it is necessary to assure silicon core masterbatch stability in process of production and silicon core masterbatch and lower feed axis It is concentric, if occur the stability of silicon core masterbatch or silicon core masterbatch and it is lower feed axis concentricity there is deviation, can direct shadow Ring the quality that silicon core draws success rate and output silicon core.Currently, pedestal generally use rod iron passes through the integrated knot of lathe process Structure, production is cumbersome, and cost is higher, and since pedestal top is directly contacted with the silicon core masterbatch of high temperature, in the effect of high temperature repeatedly Under, pedestal top screw hole and the regular deformation of screw rod are burnt out, and cause entire pedestal that can not be continuing with.

Authorization Notice No. is that the Chinese patent of 205295536 U of CN discloses a kind of silicon core furnace masterbatch firm banking, is wrapped Placement pipe and connector are included, bottom of the tube madial wall is placed and is equipped with internal thread, place on pipe side wall circumferentially arranged with several spiral shells Pit is bolted with screw rod in each threaded hole；Connector includes supporting table and connecting tube, and supporting table is fixed at the top of connecting tube, Supporting table side wall, which is equipped with, to be connect by internal thread with external screw thread with the matched external screw thread of internal thread, placement pipe with connector.It should The placement pipe of utility model and connector split settings only place pipe and contact high temperature silicon core masterbatch, when pedestal because high temperature occurs When damage, placement pipe is only needed to change, pedestal replacement cost can be effectively reduced, extends pedestal usage time；Silicon core masterbatch, which is placed in, to be put It sets in the space formed between pipe and the supporting table of connector, and fixed by placing the screw rod on pipe side wall, ensure that silicon core The proper alignment of masterbatch stability in process of production and silicon core masterbatch and lower feed axis.

But the silicon core furnace masterbatch firm banking of above-mentioned technical proposal exists：1) it places to manage to use with connector and be threadedly coupled, When placement pipe is damaged because of contact high temperature silicon core masterbatch, high warm transmits the external screw thread for being easy to cause generation connector The case where by deformed damaged, and then make connector that can not be reused, it is solved to cannot achieve the technical solution Reduction pedestal replacement cost the problem of；2) supporting table does not use heat insulation structural to design, and high temperature is easy by placing pipe, support Platform and connector are transmitted to other connecting portions such as lower axle；In addition, it is necessary to replace placement pipe, also can not fundamentally reduce into This.
