The utility model has the advantages of simple and compact structure, rationally, use simple to operate, the cost is lower, makes the operation of advance graphite card flap subassembly feasible, the indirect quantity that by a wide margin reduces graphite.
Description
Technical field
The utility model relates to polycrystalline silicon reducing furnace graphite components technical field, specifically a kind of convenient anti-lost setting tool installing polycrystalline silicon reducing furnace graphite components.
Background technology
Polysilicon is the main raw material for the production of semi-conductor and photovoltaic product, main method at present for the production of polysilicon has the method such as improved Siemens, silane thermal decomposition process, sulfuration bed process, wherein improved Siemens and silane thermal decomposition process all need deposition vehicle in reduction process, now widely used is silicon core, comprise square silicon core, circular silicon core etc., silicon core is connected by graphite components with between electrode and clamps.
Because the polysilicon large-scale production of China is started late; relevant production technology mainly rests in the minority developed country such as America and Europe, Japan hand; industry overall technology is weak, no matter in scale, quality product or in production cost control, is all in a disadvantageous position in whole international competition.So lifting prior art, reduce the task of top priority that production cost becomes numerous manufacturer.This patent is exactly the production cost of the reduction link in order to reduce polysilicon, there is provided a kind of polycrystalline silicon reducing furnace graphite components matching used instrument, allow the installation of the cheap polycrystalline reduction furnace module of handled easily again can line operate, significantly reduce the consumption of graphite from the side, and then reduce the production cost of production of polysilicon enterprise.
Traditional polycrystalline silicon reducing furnace graphite components is mainly three kinds of modes:
A kind of mode is three-piece formula, comprises graphite base, graphite nut and graphite clamping petal three part.There is screw thread graphite base upper end, can be screwed together with graphite nut, and graphite nut center is hole, pass through for graphite clamping petal part, card lobe is positioned over above graphite base, and graphite nut is connected with graphite base and after screwing, and reaches fixing graphite clamping petal and clamps the object of silicon core.This structure is comparatively complicated, can reach the object of clamping silicon core preferably, but uses quantity of graphite comparatively large, and cost is higher, installs comparatively loaded down with trivial details and inconvenient.
Another kind of mode is integral type, namely square or conical hole is processed in monoblock graphite upper end, silicon core directly inserts in hole, this mode is easy for installation, but there is the defect problems such as silicon core is difficult to clamping, whole graphite components can only use once, silicon core scale error cannot use time larger, cost is also higher.
The third mode is graphite base and graphite clamping petal is socket fitting type structure, and graphite clamping petal inserts in described graphite base; On graphite clamping petal, cover has graphite block, for isolating graphite clamping petal top and graphite base outside surface.The quick-clamping of graphite clamping petal can be realized by socket fitting type structure, and the recycling of graphite base.Make in polysilicon growth process by graphite block, silicon can not deposit on graphite base.
The third is the first and the second way comparatively, and cost of manufacture reduces greatly, and to locate more accurate simultaneously, but due to graphite clamping petal be separate type, install inconvenient, and general purpose tool is not suitable for this application.
Utility model content
Not enough for prior art, the utility model provides a kind of dependable performance, easy to operate, and lower-cost polycrystalline silicon reducing furnace graphite components, for clamping of polycrystalline silicon reducing furnace silicon core.
The technical scheme in the invention for solving the above technical problem is: a kind of setting tool for polycrystalline silicon reducing furnace graphite components, comprise clamp assemblies, it is characterized in that: described clamp assemblies is monoblock type isolating construction, comprise the left half and the right half, described the left half and the right half coordinates for clamping installation graphite components; Described clamp assemblies arranges anti-lost step, drops for preventing graphite components.
Further, the inner chamber of described clamp assemblies is circular, and profile can be circular, square, rectangle, rhombus etc.
Further, described the left half and the right half is monoblock type isolating construction, and separated track is band taper, circular arc or zig-zag.
Further, the left handle of each attended operation of described the left half and the right half and right handle.
Further, left handle and right handle are combined by bearing pin, by the clamping degree of control spring degrees of tensions control handle end, control further the closed of the left half and the right half and open and the installation of graphite components.
Further, described graphite components is arranged on middle part or the head of described left handle and right handle.
The advantage that the utility model possesses: device of the present utility model adds matching used anti-lost step and alignment shape, drops and depart from and avoid the graphite clamping petal end face in graphite components to be uneven when can prevent graphite components from placing; The utility model structure is simple, compact, reasonable, easy to install and use, and cost is lower, makes advanced graphite clamping petal assembly operation feasible, indirectly significantly reduces the consumption of graphite.
