Description
Technical field
The present invention relates to granular material processing technique field, especially a kind of grading plant for granular material.
Background technology
Silicon chip is the main production material of semiconductor and photovoltaic art, and Multi-wire wafer cutting technique is to compare in the world at present
Advanced silicon chip process technology, it is different from the cutting modes such as traditional saw blade, grinding wheel, is cut also different from advanced laser
Cut and inner circle cutting, its principle be by the steel wire of a high-speed motion drive the cutting liquid being attached on steel wire to silicon rod into
Row friction, so as to reach cutting effect, in whole process, steel wire forms a bracing cable net by the guiding of line roller on online roller,
And workpiece to be processed realizes the feeding of workpiece by the decline of workbench.Multi-wire wafer cutting technique has compared with other technologies
Efficient, the advantages that production capacity is high, and precision is high, therefore, multi-wire cutting technology are widest silicon chip cutting techniques at present.
In multi-wire cutting technology, used cutting liquid is typically the carborundum by polyethylene glycol and 1200 mesh or so
Grain is formulated according to a certain percentage, and cutting liquid inevitably mixes during cutting silicon rod with the silica flour cut
Together, substantial amounts of cutting waste liquor is formed, and breakage can occur because of dissection in part silicon-carbide particle in cutting liquid, make
The mesh number increase of partially carbonized silicon is obtained, therefore, cutting waste liquor can not be reused directly.Contain many resources in cutting waste liquor,
Such as carborundum, silica flour etc., if directly discharged, waste of resource is not only caused, while also pollute the environment, it is therefore, right
In the problem of the processing always photovoltaic industry of cutting waste liquor.
At present, for the mode below the processing method generally use of cutting waste liquor：First, solid-liquid is carried out to cutting waste liquor
Separation, i.e., the polyethylene glycol liquid in cutting waste liquor is separated with silicon-carbide particle, silicon powder particle, obtain polyethylene glycol liquid with
The carborundum solid of silica flour is mixed with, the polyethylene glycol liquid isolated can be prepared as raw material again after being processed further
Reused into cutting liquid；Then, classification processing is carried out to the carborundum for being mixed with silica flour separated, mesh number is removed and is more than
The superfine silicon carbide of 1300 mesh, the remaining less carborundum of mesh number can be made into new cutting liquid and be continuing with, due to carborundum
It is little with the density difference of silica flour, therefore, whether all contain in remaining carborundum or the superfine silicon carbide separated
Silica flour；Finally, the larger superfine silicon carbide for being mixed with silica flour of the number separated is discharged after chemical treatment.It is existing
Some cutting waste liquor processing modes can only recycle polyethylene glycol and a part of carborundum, for ultra-fine in cutting waste liquor
Carborundum and silica flour generally can not be recycled effectively.
At present, the classification processing for granular material is main by the way of pneumatic classification, i.e., is washed away using gases at high pressure
The granular material of different meshes, since the granular material particle weight of different meshes is different, make in same wind-force
Diverse location can be deposited in the granular material of lower different meshes, realizes the classification of granular material, although this mode also can
The classification of granular material is realized, still, since the weight of the granular material particle of different meshes is not much different, in high-speed flow
Under washing away, the granular material particle of different meshes still can mix, and grading effect is poor.
