Technical field
The present invention relates to a kind of industrial silicon p owder production technique.
Background technology
Silica flour is prepared from by raw material of silico briquette, is widely used in various new high-tech industries.At present, the system of silica flour
Preparation Method is crushed afterwards first to clean, and, typically using flushing or foam washing, not only cleaning efficiency is low, and the work of workman is strong for the method for cleaning
Degree is big, and the effect of cleaning is poor；And breaking method is generally crushed or direct impact comminution using directly extruding, crushing
Cheng Zhongjun is not collected to the powder in air so that there is substantial amounts of powder in air, once run into naked light will send out
Raw blast.Therefore, on the premise of processing efficiency is ensured, how safely to produce silica flour is the technology for just endeavouring to solve in industry
Problem.Therefore, existing silica flour manufacturer all can dispose a bag dust collector in workshop or production silica flour equipment, but
It is that the dust removing effects of existing bag dust collector are not obvious, that is, allows to collect dust, but because of complex structure, cause dust
Cleaning is inconvenient, and dust collects inconvenient.
Furthermore, at present in the production process of high purity metal silica flour, often suppress dust extraction outlet using running water injection
Need to open deduster water valve with environment purification, before production, using spray atomizing running water, at source outlet carrying out sprinkling blocks
Cut, and droplet size is adjusted by the independent assortment of nozzle, the fine dusts in air is fallen with droplet, reach optimization ring
The purpose in border.The method of this kind of dedusting both waste water resource, increases operation cost of enterprises, again cannot be in dusty gas
Tiny silica flour is effectively reclaimed, and is unfavorable for environmental protection.
Therefore, in sum, existing industrial silicon p owder production technique very complicated, high cost, dust removing effects difference cause
Environmental pollution is serious, and when silica flour is produced, it is impossible to the Si powder in air is collected the problem for reclaiming and obtaining high-quality silica flour.
The content of the invention
The technical problem to be solved in the present invention is to provide and a kind of carries out producing high-quality by enclosed production unit
Silica flour, reduces the pollution to environment in process of production, is conducive to cost-effective industrial silicon p owder production technique.
To solve the above problems, the present invention is adopted the following technical scheme that：
A kind of industrial silicon p owder production technique, comprises the following steps：
1) silico briquette is crushed：Silico briquette in first feed hopper is transported in disintegrating machine, silico briquette is carried out instead by disintegrating machine
It is multiple broken, silica particle is obtained, while 0.1% silica flour that silico briquette is produced in shattering process was carried out by sack cleaner
Filter is collected, and obtains silica soot, and is recycled, standby；
2) silico briquette particle removes iron：By silico briquette particles of the specific steps A after broken by elevator it is slow be transported to second to
In feed bin, while deironing device of pipeline is provided between elevator and feed hopper, by deironing device of pipeline by silico briquette particle
Iron tramp carries out adsorption removal, and iron-free silica particle is obtained, standby；
3) silico briquette particle powder：To be stored in the iron-free silica particle input punching rotation flour mill in the second feed hopper, together
Shi Tianjia cooling waters, can cool down, it is to avoid silica flour density is excessive to be led during punching rotation flour mill at a high speed powder processed
Explosion accident is caused to occur, meanwhile, silica flour obtained in punching rotation flour mill carries out vibrations screening by bobbing machine, by the filtering of middle powder, sieve
The bulky grain silica particle that choosing is obtained is again fed to carry out punching rotation powder processed in punching rotation flour mill；
4) powder pulse dust removal processed：In step 3) in rush rotation flour mill powder and bobbing machine screening during can produce
, be collected for the powder of generation by pulse dust collector by substantial amounts of powder, obtains silica fine powder, standby；
5) silica flour packaging：A, step 4) in powder is obtained into crystal silicon powder by packing machine in the silicon that obtains after bobbing machine screening；
B, step 4) in punching rotation flour mill powder and bobbing machine screening process in produce powder by pulse dust collector collection obtain
Fine powder, is then obtained into crystal silicon powder by fine powder by packing machine；
6) silica flour packaging dedusting：Step 5) in specific steps A and specific steps B silica flour packaging process in can produce
, be collected for silica soot by sack cleaner by 0.01% diffussion of dust, and is recycled.
Beneficial effects of the present invention are：The industrial silicon p owder production technique quickly can not only be produced silico briquette, be obtained
To high-quality silica flour, and the production equipment that the industrial silicon p owder production technique is used is closed unit, and by pocket type
Deduster and pulse dust collector are aided in, and can be recycled dust, while also reducing pollution of the dust to environment.
Specific embodiment
