Description
Technical field
The utility model is related to a kind of Electronic Control, mechanically decoupled system regions, and in particular to a kind of suitable for silicon factory
Based Intelligent Control dispensing piece-rate system.
Background technology
Silicon is that one kind has two kinds of allotropes of amorphous silicon and crystalline silicon, and crystalline silicon is grey black, metallic luster, molten point
Height, hardness is big, and quality is crisp, and electric conductivity is semiconductor.With developing rapidly for science and technology, China is increasing to the demand of silicon,
Although silicon is only second to oxygen in the content of the earth's crust, mass fraction is 26.3%.But the element that element silicon is not found earliest, that
Because by Si reduction be out an extremely difficult thing from the oxide of silicon, so the price of silicon is not cheap.
Silicon processing enterprise can all produce substantial amounts of waste and old silicon material in process of production, for economic and environment-friendly, saving nature money
Source, meets the demand of contemporary green industry, enterprise all can waste material silicon material be collected, reuse.In the prior art to waste and old
The collection of silicon material generally comprises following operation：1st, it is just broken, using manually by the larger silicon material of particle select come；2nd, break again
Broken, the silicon in white residue after manually being crushed using chopsticks or tweezers selects to be collected.But due to the particle of white residue
Very small, not only efficiency is low for the mode for being sorted to white residue by the way of artificial in the prior art, and can waste a large amount of
Human cost, increase business burden.
In addition, iron powder is a kind of most important metal dust in powder metallurgy industry.Iron powder is used in powder metallurgy production
Amount is maximum, and its consumption accounts for 85% or so of metal dust total flow, and the staple market of iron powder is manufacture machine components, its
Required iron powder amount accounts for the 80% of iron powder total output.
In the industrial production, iron powder and silicon are mixed into making mixture or processing device is very common, but system
Containing a large amount of unrecovered iron powders and white residue in the waste material of generation after having made, in the prior art usually by iron powder and white residue burial
Reason, especially pollution of the iron powder to environment is very big, simultaneously as iron powder is expensive, directly buries to fall not only to waste by iron powder
Resource, further increases the cost of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of Based Intelligent Control dispensing piece-rate system suitable for silicon factory, is realized a kind of
By electronic technology automatic mixing iron powder and the weight of watery hydrochloric acid, primary dcreening operation is carried out to the silicon in white residue using ferrous acid mixed liquor,
The collection rate to the silicon in white residue is improved, while the iron in ferrous acid mixed liquor reclaim the purpose of collection, existing skill is solved
Efficiency is low by the way of manual sorting sorts to white residue in art, human cost big, and ferrosilicon in industrial waste is mixed
Iron in compound can not be recycled, and the iron powder after white residue is separated especially with iron powder can not be recovered, and cause resource
Waste the problem with environmental pollution.
The utility model is achieved through the following technical solutions：
