Abstract
The utility model provides a clamping device, which relates to the field of polysilicon production. A graphite fastening valve is installed on a graphite seat through a graphite cap; the graphite cap is connected with the graphite seat through threads; a circular hole and a cruciform slot which are perpendicular are arranged at the center of the graphite fastening valve; and the axis of the circular hole inside the graphite fastening valve is coincided with the center line of the cruciform slot. The clamping device has the advantage of reliable and convenient assembly, overcomes fragileness of silicon chips, solves the problem of assembling the square silicon chips on a reduction furnace and the problem of stick falling in furnace opening and an initial stage of production, and ensures furnace opening success rate reaching more than 99%. Moreover, production cost can be reduced by adopting the clamping device to clamp the square silicon chips to produce polysilicon. As the square silicon chips are more convenient to be processed, the square silicon chips can be produced on a large scale, and the production efficiency of the polysilicon is also improved.
Description
Technical field
The utility model relates to field of polysilicon production, and particularly silicon core in the side's of employing is produced a kind of clamping device of polysilicon.
Background technology
Domestic columniform silicon cores that adopt in production of polysilicon at present more, the problem of existence is to produce the restriction that is subjected to silicon core stove per unit area yield in enormous quantities, can't satisfy the needs of producing polysilicon plant produced more than 1000 tons per year; Adopt the large-scale wire cutting machine can large batch of producer silicon core, but does not still have special clamping device at present at square silicon core.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of clamping device, assembly problem that can solution party's silicon core, and open stove and production initial stage and fall the problem of rod.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of clamping device, and graphite card lobe is installed on the graphite seat by the graphite cap, and the graphite cap is connected with the graphite seat by screw thread.
Graphite card lobe center is provided with vertical circular hole and cross recess.
The axis of circular hole and cross recessed central lines in the graphite card lobe.
A kind of clamping device that the utility model provides, graphite card lobe is installed on the graphite seat by the graphite cap, and the graphite cap is connected with the graphite seat by screw thread.Graphite card lobe center is provided with vertical circular hole and cross recess.The axis of circular hole and cross recessed central lines in the graphite card lobe.The utlity model has assembling reliably, advantage easily, overcome silicon core brashness, solve the problem of the reduction furnace side of assembling silicon core, and open stove and excellent problem of production initial stage, and guarantee the blow-on success ratio more than 99%, adopt the utility model clamping side silicon core to produce polysilicon, can reduce production costs, more convenient because of square core silicon processing, can be mass-produced, also improved the production efficiency of polysilicon.
On graphite card lobe, open vertical circular hole and cross recess, can on graphite card lobe, form eight knuckle lines, wherein the verticality of circular hole must be guaranteed, can reduce down the probability of rod like this, square silicon core through chamfering or rounding can easier be inserted in the middle of eight knuckle lines of graphite card lobe, between graphite card lobe and the square silicon core is shrink-fit, guarantee the clamping of graphite card lobe the other side silicon core, article eight, forming reliable line between knuckle line and the square silicon core contacts, can guarantee that the contact in conductivity is reliable for effect, avoid that local temperature rise to occur too high because of loose contact.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a clamping device structural representation in the utility model;
