Description

A kind of metallic silicon power processing special production line
Technical field:
The present invention relates to the processing of metallic silicon power, particularly a kind of metallic silicon power processing special production line.
Background technology:
Metallic silicon is the product smelted in electrothermal furnace by quartz and coke, and the content of principal component element silicon, about 98%, is the raw material of electronics industry hyperpure silicon, is also the basic material of solar photovoltaic industry.Silica flour be exactly utilize different physics and chemistry methods to be prepared into there is the metallic silicon particle thing that certain particle size requires.The microstructure of silica flour, the factor such as specific area and particle diameter all directly have influence on the application of silica flour downstream process deeply industry.At present, the development of method through the several years of domestic prior art crushing metal silicon has substantial progress, and more representative is Raymond mill, disc mill (vertical mill), roller-crushing mill, rush rotating grinding machine etc.Metal smelting silicon belongs to high energy consumption industry, the metallic silicon market price was also that when the river rises the boat goes up in recent years, therefore the efficiency utilization of metallic silicon is seemed particularly important, above-mentioned several size reduction machinery because of its pulverization principle too single, the problems such as Design of Mechanical Structure existing defects, not wear-resisting, maintenance rate is high, energy consumption is large, pollution are in industry never well applied.
Metal current silicon deep processing enterprise all runs into certain technical barrier, example: existing process equipment all fails fundamentally product silica flour quality effectively to be promoted, and there is the phenomenon that crudy is lower, more to the wastage of material of metallic silicon, these all cause processing enterprise's processing cost of metallic silicon higher, and working (machining) efficiency is lower.
Summary of the invention:
The object of this invention is to provide a kind of structure improvement, result of use is good, working (machining) efficiency is high metallic silicon power processing special production line.
Technical scheme of the present invention is, a kind of metallic silicon power processing special production line, it comprises Special particle mill for metal silicon, spiral air-lock valve, it is characterized in that: raw material feed bin is sent to fine crusher by oscillating feeder, the discharging opening of fine crusher is communicated with thick chain bucket, thick chain bucket imports particle feed bin, particle feed bin lower end is provided with electro-vibrating feeder, particle feed bin is directed to little screen(ing) machine, the hopper top of electro-vibrating feeder is provided with permanent magnet, the feed opening of little screen(ing) machine imports Special particle mill for metal silicon, the discharging opening of Special particle mill for metal silicon is communicated with cyclone separator, cyclone separator top exit expects that pulse dust collector is communicated with by pipeline with drawing, the air outlet drawing material pulse dust collector is connected with air-introduced machine by pipeline, be provided with thin chain bucket at the discharging opening of cyclone separator, thin chain bucket imports swinging screen, is provided with feed back belt conveyor at the feed opening of swinging screen, feed back belt conveyor guiding coarse fodder bucket elevator.With thin chain bucket UNICOM be provided with pulse dust collector.Described fine crusher is hammer mill.Described particle feed bin upper end is provided with level-sensing device.Described pulse dust collector is provided with pressure sensor.
The invention has the beneficial effects as follows:
1, whole production line flow process is through multi-faceted optimal design, and every device obtains optimum application, when not increasing other equipment, enhancing productivity, ensureing silica flour quality, and reducing floor space, reduce base and equipment investment, increase economic efficiency;
2. yield rate is high, and fine powder rate is low.This production line adopts metallic silicon power to process after special grinding machine realizes mechanical crushing and causes that cyclone separator sieves after carrying out high efficiency feed separation by pulse dust collector (drawing material) again, crushing material moment is taken away by wind, mechanical crushing is adopted to combine with selection by winnowing mode crushing metal silicon, there is not separating twice, greatly improve the specific area of yield rate and product particle;
3. have the features such as energy consumption is low, noise is little, no dust pollution, the operation of production line whole process is negative pressure state, environment protection standard;
4. rub proofness is high, and all have high-abrasive material with silica flour contact site, greatly extends service life, failure rate is low, easy to maintenance;
