Description
Technical field
This utility model belongs to magnetic devil liquor recovery process field, more particularly, it relates to one is divided based on high-pressure filteration
Magnetic flow liquid recycling and processing device from effect.
Background technology
MRF, is that the rheological characteristic utilizing Magnetorheologicai polishing liquid in magnetic field carries out local shape modifications and polishing to workpiece
Technology.Magnetic flow liquid is by carrier fluid (such as water, silicone oil etc.), discrete polarizable micron order magnetosensitive microgranule, surfactant, throwing
Light granule and the additive composition with other functions.Magnetic flow liquid is brought into by polishing disk circulation and is formed between workpiece and polishing disk
Fine pitch polishing area in, in this region, magnetic flow liquid under the effect of high-gradient magnetic field, occur rheological effect and become
Firmly, viscosity increase, magnetic-particle therein arranges chaining along the direction of magnetic field intensity, forms the effigurate protruding satin of tool
Band, and polishing powder granule therein does not have magnetic, therefore can be extruded and float to the weak top of magnetic field intensity, so go up edema over the face
The protruding ribbon one layer of polishing particles just constitutes one " flexible polishing mould ", when this flexible polishing mould is in the drive of moving coil
Under when flowing through the small-gap suture that workpiece and moving coil are formed, surface of the work can be produced the biggest shearing force, to surface of the work material
Realize removing.In the whole course of processing, magnetic flow liquid, by blood circulation control, is stored in the comprehensive container tank of aluminum, by defeated
Go out and be pumped into output pipe, then be sprayed onto on polishing disk by nozzle, leave the magnetic flow liquid after machining area and passed through back by recovery pump
Closed tube road, is recovered in comprehensive container tank.
After using magnetic flow liquid for a long time, the consume of its magnetisable material and carrier fluid and the degeneration of additive, cause it
The index dramatic decrease such as mechanical property, magnetic performance, response time, the most modal way is for changing magnetic flow liquid, by former
Degradation magnetic flow liquid is had to recycle.Because magnetic flow liquid contains substantial amounts of ferromagnetic material, multiple compounds matter group
The carrier fluid become, complicated component, if dealt with improperly, easily environment is worked the mischief.But so far, magnetic flow liquid is carried out back
Device or method that receipts process are considerably less, and only several relevant patent documentations exist the blank of research.As, Chinese patent Shen
Please number be 201410508382.9, Shen Qing Publication day be that the patent application document on January 21st, 2015 discloses a kind of big flow
Magnetic flow liquid retracting device, including: it is arranged on magnetic flow liquid and just departs from neighbouring position and the buff wheel holding flexibility of polishing area
The recovery head of linear contact lay, it goes for receiving by the magnetic flow liquid thrown away bottom buff wheel；The vacuum being connected with described recovery head
Generating means, it is used for providing the power reclaiming magnetic flow liquid.But the device disclosed in this patent is mainly used for collection to be left
Magnetic flow liquid behind polishing region, is not directed to the recycling after magnetic flow liquid lost efficacy.
About the recycling of inefficacy magnetic flow liquid, research report little, through retrieval, Chinese Patent Application No. is:
201511025405.1, Shen Qing Publication day is that the patent application document on March 23rd, 2016 discloses a kind of magnetic flow liquid recovery
Device and control method thereof and component manufacturing method, this invention is completed mixing by filtration, the adsorption of electro static filtering plate
The preliminary treatment of liquid, in recycling, adsorption tube, lower adsorption tube complete the process to mixed liquor further with ribbed pipe absorption, and increase
If heater, agitator and blood circulation, reach magnetisable material and purpose that solvent is completely separated.But the recovery of this invention fills
Put process during there is following weak point: (1) is because of its adsorption tube and ribbed pipe limited amount, it is impossible to ensure solution and its
It is fully contacted, causes treatment effect low；(2) simultaneously complex-shaped because of adsorption tube and ribbed pipe, is unfavorable for processing, is also unfavorable for
Collect the absorption magnetisable material on surface；(3) solution circulating rate in a device is relatively low, and flows to poor controllability, reduces
Treatment effeciency.And for example, Chinese Patent Application No. is: 201511025384.3, and Shen Qing Publication day is the patent on April 6th, 2016
Application documents disclose a kind of magnetic flow liquid multi-stage treatment units and control method thereof and component manufacturing method, including preposition piston
Cylinder, in put piston cylinder, rearmounted piston cylinder, preposition piston, in put piston, rearmounted piston, prefilter case, in put Rose Box, after
Put Rose Box, forward filtering net, in put drainage screen, rearmounted drainage screen, described preposition piston cylinder is by bolt and preposition piston
Being connected, described preposition piston matches with the inner chamber of prefilter case, and described prefilter case is vertically placed, and its axis is
Vertical direction, device disclosed in this patent of invention does not only exist defect present in above-mentioned patent, uses multistage place because of it simultaneously
The mode of reason, causes device volume excessive, operation inconvenience, the problem that cost is high.
For the research blank problem existed in current inefficacy magnetic flow liquid recycling field, it is badly in need of development and sets accordingly
Standby and processing method, processes discarded magnetic flow liquid, can not only reduce the pollution to environment, and can be to wherein
Related substances recycle, save the energy.
Summary of the invention
Problem to be solved
Lack relevant high efficiente callback processing means for current magnetorheological waste liquid, and cause it after abandoning, environment to be caused
Polluting, and cause the problem of energy waste, this utility model provides a kind of magnetic flow liquid based on high-pressure filteration centrifugation to return
Receiving processing means, the main discrete particles of magnetic flow liquid can be separated with carrier fluid by device of the present utility model with processing method, main
If for the magnetic flow liquid high treating effect of main discrete particles Yu carrier fluid soap-free emulsion polymeization effect, both being separated, for rear
Continuous recycling provides may.
