Abstract
The invention discloses a roller table transportation and crushing production line technology for polycrystalline silicon, and relates to the technical field of polycrystalline silicon production. The technology comprises the steps of bar dismounting, crushing, sorting and screening, total pneumatic operation is performed, the operation process is free of oil, water and pollution, and low-pressure staring and high-frequency impact are adopted; a 1.8 m-2.4 m bar is crushed only in 10 seconds, the crushing process does not produce dust, and a crushing impact head adopts a tungsten-cobalt alloy or PTFE (polytetrafluoroethylene), so that polycrystalline silicon is not polluted; and equipment is simple to operate, safe and reliable, the overall layout is compact in structure, smart and efficient, surfaces contacted with crystal bars and polycrystalline silicon particles adopt high-quality 316 SS processed with a carbon tungsten alloy technology, so that pollution to polycrystalline silicon particle size is small, and the purity of the polycrystalline silicon particle size is high.
Description
Technical field:
The present invention relates to technical field of polysilicon production, be specifically related to polysilicon roller transport crushing production line technique.
Background technology:
Concerning polysilicon producer outlet, the mass ratio of polycrystalline silicon briquette shape size scope control, that is exactly the lifeblood of wealth, all under stagnant prerequisite, more seems particularly important especially in photovoltaic industry at present! The key link that breaking polycrystalline silicon is indispensable.Existing breaking polycrystalline silicon mostly is hand breaking, pollutes greatly, and purity is lower.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, provides a kind of pollution to polysilicon granularity little, the much higher crystal silicon roller transport of the purity crushing production line technique of polysilicon granularity.
Technical problem to be solved by this invention realizes by the following technical solutions.
Polysilicon roller transport crushing production line technique, it is characterized in that: mainly comprise the following steps: tear excellent manipulator open and retract the U-shaped excellent roller transport car → roller transport car of U-shaped rod → put into and send U-shaped rod in dressing floor, to be organized into single silicon rod → by single silicon rod feeding manipulator to arrange between inspection vehicle → U-shaped rod, placing single silicon rod send silicon rod to disintegrating apparatus → by single silicon rod feeding manipulator to single silicon rod roller transport car → single silicon rod roller transport car, piling up silicon rod to predetermined number → silicon rod to disintegrating apparatus material loading platform piles up complete, sensor startup automatic pulverizing equipment carries out fragmentation → particle and flows into successively sorting belt feeder, by the underproof sandwich of manual sorting particle → shirt rim belt elevator machine, send silicon rod particle after sorting to pulley type vibrating screen classifier, carry out sorting → pulley type screening machine and carry out particle sorting.
Broken impact head tungsten-cobalt alloy or PTFE on disintegrating apparatus.
The high-quality 316SS that all adopts diamondite PROCESS FOR TREATMENT to cross with crystal bar and polysilicon particle contact-making surface.
Beneficial effect of the present invention is: pure pneumatic execution, the course of work is without oily, anhydrous, pollution-free, low voltage starting, high-frequency percussion.The bar of 1.8m～2.4m has only smashed within 10 seconds, shattering process does not produce dust, broken impact head tungsten-cobalt alloy or PTFE, pollution-free to polysilicon, equipment operating is simple, safe and reliable, integral layout compact conformation, intelligence, efficient, with the high-quality 316SS that crystal bar and polysilicon particle contact-making surface all adopt diamondite PROCESS FOR TREATMENT to cross, little to the pollution of polysilicon granularity, the purity of polysilicon granularity is high.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Polysilicon roller transport crushing production line technique, mainly comprise the following steps: tear excellent manipulator open and retract the U-shaped excellent roller transport car → roller transport car of U-shaped rod → put into and send U-shaped rod in dressing floor, to be organized into single silicon rod → by single silicon rod feeding manipulator to arrange between inspection vehicle → U-shaped rod, placing single silicon rod send silicon rod to disintegrating apparatus → by single silicon rod feeding manipulator to single silicon rod roller transport car → single silicon rod roller transport car, piling up silicon rod to predetermined number → silicon rod to disintegrating apparatus material loading platform piles up complete, sensor startup automatic pulverizing equipment carries out fragmentation → particle and flows into successively sorting belt feeder, by the underproof sandwich of manual sorting particle → shirt rim belt elevator machine, send silicon rod particle after sorting to pulley type vibrating screen classifier, carry out sorting → pulley type screening machine and carry out particle sorting, wherein broken impact head tungsten-cobalt alloy or the PTFE on disintegrating apparatus, the high-quality 316SS that wherein all adopts diamondite PROCESS FOR TREATMENT to cross with crystal bar and polysilicon particle contact-making surface.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
