Description
Technical field
The utility model relates to the novel shredder assembly in materials processing technology field, particularly polycrystalline silicon rod.
Background technology
Polysilicon is the basic raw material of photovoltaic industry the most, has obtained volatile development in recent years at home.The polycrystalline silicon rod that production obtains in reduction furnace need be broken into block raw material and pack storage, and block raw material also is to carry out the necessary basic demand of silicon single-crystal production; During the state of the domestic short run of production of polysilicon several years ago, because there is fatal defective in other Mechanical Crushing method of employing, the former capital is to adopt the crumbling method of direct hammering to produce.Disclose a kind of hammer for breaking polycrystalline silicon as Chinese patent application 200810146324.0, possessed the shank that extends along medullary ray, at the top end edge of above-mentioned shank and the head of the crisscross extension of above-mentioned centerline direction.Above-mentioned head has: the counterweight portion of the strike portion that is connected with above-mentioned shank bonded head body, via an end that links axial region and above-mentioned body and the other end that is arranged on above-mentioned body.Above-mentioned body, above-mentioned binding axial region, above-mentioned strike portion and above-mentioned counterweight portion are integrally formed by superhard alloy.In above-mentioned strike portion, be formed with the scope of attack that becomes convex surface.This hammer for breaking is the improvement of typical conventional tool.The drawback of the direct hammering fragmentation of silicon rod has: 1, labour intensity is big, though hard silicon rod is strong than the embrittlement property opened, the size range that is crushed to requirement with special hand hammer is also relatively more painstaking; Obvious this mode is not suitable for scale operation.2, the fragmentation of short run adopts hammering still can carry out, and is not fit to large-scale production; Positive mechanical fragmentation (as jaw crusher) can produce iron pollution; 3, Zui Da technical problem is: no matter hammering or other Mechanical Crushing, the one, very easily bring metallics to pollute to product, the 2nd, can produce the fine particle fragmentation of a large amount of laminar, needle-likes and dust-like, such fine particle becomes the occurrence cause of dust, intractable.And the particle of diameter below 150 microns is owing to need the discarded processing of prudent do by the danger of catching fire.Therefore, the shortcoming of these class methods is: can pollute silicon rod, produce a large amount of dust, reduce yield, increase the offal treatment cost, not be suitable for scale operation.
It is reported classical silicon rod production method--be widely used in-Siemens Method numerous newly-built the enterprise at home.Therefore, change breaking polycrystalline silicon technology and just become the task of top priority to overcome the problems referred to above.
The disclosed classical production method by the innovation silicon rod of Chinese patent literature (patent No. ZL01801220.5) makes silicon rod have " bubble " in process of production so that broken; Because inside has bubble, apparent density is 2.20g/cm
3Following band bubble polysilicon.The generation of this silicon minuteness particle when fragmentation is considerably less, and can pulverize easily.Such silicon falls the drop of hydrogeneous fused silicon by in the presence of hydrogen naturally in 0.2～3 second time, make it to be cooled to be closed with the state of bubble hydrogen in the drop and make.Such silicon makes in having the device of following structure, the supply-pipe of separating out fusion, chlorosilane class that promptly carries out silicon in cylindrical container is inserted into the silicon melting zone in the cylindrical container, supplies with sealed gas in the gap of the supply-pipe of cylindrical container and chlorosilane class.This silicon rod production method has much application unknown in commercial running is produced.But change the production unit and the technology of polysilicon routine, promote having great difficulty.
