Description
Technical field
The present invention relates to a kind of filter that includes solid matter liquid, be specifically related to a kind of for include size two kinds of different-grain diameter solid matter used cutting liquids elutriation divide filter device.Belong to industrial wastes treatment technology.
Background technology
At field of industrial production, often there is the discharging of waste liquid that includes solid matter, this not only can cause environmental pollution, but also can waste available resources.
Such as the industrial production of silicon chip, the conventional mortar that contains granulated carbon SiClx and polyethylene glycol composition, as the cutting liquid of silicon chip.And in the described cutting liquid (mortar) after silicon chip cutting, except granulated carbon SiClx, also contain granule crystal silicon, thereby make described used cutting liquid become granulated carbon SiClx, granule crystal silicon and polyethylene glycol ternary two-phase liquefied mixture.
And in described ternary two-phase liquefied mixture, the particle diameter of granulated carbon SiClx is generally within the scope of 0.06～0.20um, and the particle diameter of granule crystal silicon is generally within the scope of 0.01～0.05um.That is to say that crystal silicon particle is much more tiny than silicon-carbide particle.
Because carborundum and polyethylene glycol all have the value of recycling, therefore, industrially usually can implement to refine regeneration to described waste mortar (cutting fluid) and process.Having regeneration treatment technology is, first in waste mortar, adds after a certain amount of water purification, desalinates press filtration, isolates carborundum and crystalline silicon mixture; Rear heating evaporation is removed indivisible moisture, then through concentration extraction polyethylene glycol.
Existing regeneration treatment technology exists an obvious deficiency to be, in the described mixture through separating, the crystalline silicon that contains more content, if by the described mixture of separating, as the reuse of cutting mortar raw material, so due to the existence of crystalline silicon, will directly affect cutting (cutting) effect and the cutting accuracy of crystal silicon chip, this is that industrial silicon chip production is not welcome, and is also can not be received.
For this reason, research and develop a kind of can be in used cutting liquid (mortar), the used cutting liquid that effectively minute leaches respectively carborundum and crystalline silicon divides filter device, just becomes expectation in the industry.
Summary of the invention
The present invention aims to provide and a kind ofly for including the elutriation of used cutting liquid of two kinds of different-grain diameter solid matters of size, divides filter device, effectively to overcome the deficiency of prior art.
The present invention realizes the technical scheme that its object takes:
