Abstract
The invention relates to a full-automatic mechanized polycrystalline silicon crusher. Silicon bars with a preset quantity are piled in a bar storage mechanism; a discharge hole vibrator arranged at an outlet of the bar storage mechanism is started to convey the silicon bars to a feeding mechanism; a lifting mechanism lifts the silicon bars to a height as required; the silicon bars are aligned, leveled and then conveyed to a main mould of the crusher by a roller conveyer mechanism under the drive of the feeding mechanism; when the main mould of the crusher is detected to be filled with the silicon bars by a photoelectric sensor, a electromagnetic sensor starts linked impact cylinders arranged at the periphery of the main mould of the crusher to impact and crush the silicon bars with large impact force controlled by the electromagnetic sensor; and the electromagnetic sensor starts the cylinders to open or close at random, so that the crushed silicon bars are discharged to a discharge groove. According to the invention, the manual operation is discarded, and the machine is adopted to substitute the manual crushing operation, so that the intelligent, efficient and full-automatic mechanized work is realized; and the production efficiency is improved, the quality of the product is ensured, and the production cost and the human resources are saved.
Description
Technical field
The present invention relates to a kind of full automatic mechanical breaking polycrystalline silicon machine, belong to polysilicon bar Mechanical Crushing field.
Background technology
Polysilicon is good semi-conducting material, is widely used in solar power generation cell plate.Topmost raw material in photovoltaic industry.From the reduction furnace U-shaped silicon rod that out 2.8m grows, form the cell panel of solar electrical energy generation in photovoltaic industry, just must carry out roughing, length: 1.8m～2.4m, diameter:
silicon rod, is broken into granularity and is
following fragment or particle, then cast by ingot furnace
silicon ingot, then cut into solar panel, for the use of photovoltaic generation.
Domestic polysilicon industry, relies on and manually with steel hammer tungsten carbide button, carries out hand-crushed always for many years.
This hand-crushed method of always continuing to use, directly adopts tungsten carbide hammer to pound to knock broken; Even in the more flourishing western countries of polysilicon technology, adopt too hand-crushed.Owing to manually knocking: be subject to the restriction of muscle power and serious dust pollution, efficiency is very low.Thereby the production capacity that blocked silicon rod fragmentation, has seriously hindered the development that silicon rod is transformed into photovoltaic industry.Base this, the silicon rod disintegrating machine of full-automatic, mechanization, high efficiency smart is ready to appear! Domestic crushing mechanism industry is exploitation and development one after another also.
" hammer mill " that have the > > of < < Shenyang Univ. of Science and Engineering development of putting on market at present.Its operation principle is: by step motor control jump bit stroke, jump bit, under the control of clutch, promoted and fall, and then reaching the impact of polysilicon bar and broken object.By the execute-in-place experiment of " middle energy " in Xuzhou, its operating efficiency does not reach calculated value.Finally can only abandon, continue to continue to use hand breaking.
Also have such as breaking polycrystalline silicon device on the market, all adopt artificial hand-held single cylinder to impact, and so on.No matter output and efficiency, all do not reach the requirement of polysilicon industry to breaking polycrystalline silicon.
Changzhou Jing Pu automation equipment Co., Ltd, puts on market by the transformation to traditional jaw crusher, be known as breaking polycrystalline silicon machine, but it can not process 1.8m～2.4m, diameter
silicon rod.Will use this jaw crusher, first must carry out precrushing to the long bar of polysilicon, the Full-automatic mechanized that therefore still can not realize polysilicon is broken.
In sum, develop efficient, intelligence, full automatic mechanical breaking polycrystalline silicon machine is what the trend requires.
Summary of the invention
Object of the present invention, be to provide a kind of full automatic mechanical breaking polycrystalline silicon machine, be characterized in: fundamentally discard the manual operations of polysilicon bar being continued to use always to hand breaking, use machinery to replace people's fragmentation procedure, realize intelligence, efficient, full-automatic, do mechanization operation.Improve production efficiency, guaranteed product quality, saved production cost and human resources.
Technical scheme of the present invention is: a kind of full automatic mechanical breaking polycrystalline silicon machine, comprise, broad-adjustable polysilicon length bar is laid in mechanism, discharging opening vibrator, feeding mechanism, stub material deposit groove, stub material propulsion cylinder, roller hoisting mechanism, roller delivery mechanism, disintegrating machine body die, the blow cylinder of interlock, blowpit, folding cylinder, electromagnetic sensor, photoelectric sensor, electromagnetic proximity switch; Wherein, the silicon rod material of predetermined number, piles up in bar deposit mechanism, can pile up the long bar of 1.8m～2.8m in this mechanism; The discharging opening vibrator that is placed in this bar deposit mechanism exit starts, and silicon rod material is delivered to the feeding mechanism being positioned at above hoisting mechanism; And by lift mechanism lifts to feeding mechanism desired height; Under feeding mechanism thrust promotes, by the roller delivery mechanism near feeding mechanism, by after silicon rod material straightening smoothing, deliver to and be arranged in the disintegrating machine body die connecting with roller delivery mechanism; When photoelectric sensor detects disintegrating machine body die and has been full of silicon rod material, electromagnetic sensor is enabled in the blow cylinder of disintegrating machine body die interlock around, and each blow cylinder is under the control of electromagnetic sensor, with powerful impulsive force, impact silicon rod, and smash silicon rod; Electromagnetic sensor random start folding cylinder, discharging is to blowpit.
This breaking polycrystalline silicon machine also comprises, stub material deposit groove, and this stub material deposit groove can be piled up the stub material of length 200mm-500mm;
Described stub material deposit groove, be positioned at above-mentioned bar and lay in the vertical side of mechanism's direction, this stub material deposit groove, by stub material, is carried by a stub material propulsion cylinder, to described roller hoisting mechanism, by hoisting mechanism, silicon rod material is promoted to feeding mechanism by preset height; Continue again to lay in the identical operation below of mechanism with described bar.
The blow cylinder of described interlock, by the broken cylinder in outside, the broken cylinder in top side, inboard broken cylinder forms, and described cylinder lays respectively at outside, top side, the inboard of disintegrating machine body die.
Described disintegrating machine body die, is built-in with downside rolling steel ball and upside rolling steel ball, is supporting silicon rod material.
The invention has the beneficial effects as follows: the present invention is a kind of full automatic mechanical breaking polycrystalline silicon machine, the whole course of work is without oily, anhydrous, pollution-free, low voltage starting (0.6MP), high-frequency percussion (frequency of impact 30Hz).The bar of 1.8m～2.4m has only smashed within 10 seconds.Shattering process does not produce dust.Broken impact head contact-making surface diamondite, can not cause polysilicon to pollute.According to different silicon rod size and porousnesses, coordinate different M heads or crescent moon and M Combined impact to tap the head, reach the particle size after cracking of user's appointment.Equipment operating is simple, safe and reliable.Integral layout compact conformation, intelligent and high-efficiency, all adopt high-quality stainless steel with crystal bar and polysilicon particle contact-making surface, and 304.Pollution to polysilicon granularity is almost nil, can make the purity of polysilicon granularity up to 99.9999%.Realized efficient, intelligent.
