Description

Cutting fluid purifies uses accurate treatment unit

Technical field

The present invention relates to a kind of filtration unit.Specifically, be to be used in the elimination cutting fluid cutting fluid of greasy dirt and impurity to purify and use accurate treatment unit.Be applicable to the purifying treatment of mechanical processing industry cooling with cutting fluid.

Background technology

All know at mechanical processing industry, to the car of workpiece, grind, cut, roll etc. in the course of processing, generally use cutting fluid to come the processing units of lathe and so on is cooled off, so that prolong the work-ing life of processing units.Cutting fluid in use has metal-powder, dust and greasy dirt unavoidably and sneaks into wherein, and along with metal-powder, dust and smeary in the cutting fluid are on the increase, cutting fluid is understood putrid and deteriorated and can't be used.Therefore, need often used cutting fluid to be carried out purifying treatment.

Apparatus for purifying cutting liquid mainly contains following several kinds at present.The one, gravitational separation device, it is according to the light principle of oil ratio water, utilizes gravity to dispose the most of oil slick in the cutting fluid, but can't dispose the oil of other form; The 2nd, centrifugal separating device, this device are to utilize profit density different characteristic, and the cf-principle different with centripetal force of in high speed rotating unit, utilizing profit to produce can be disposed macrobead oil, but can't dispose oil in water emulsion and dissolving oil in the water.The 3rd, the steel band type skimming plant, it is through lipophilic steel band the oil slick in the water to be adhered on the steel band, thereby takes oil slick out of the water surface.This method can only be disposed most of oil slick, also can't handle the oil of other form; The 4th, filtration unit; Like chain-plate type filtration unit, net formula filtration unit, belt filtration unit, cake layer filtration unit and deep-bed filtration device etc.; These filtration units all are to be medium with the porous mass, and solid particulate and oil droplet are trapped on the porous medium.If the filtration unit aperture is too big, the oil droplet littler than the aperture is difficult to be trapped, and it is not thorough to make greasy dirt handle.Too little like the aperture, the aperture is blocked easily.Therefore, the treatment effect of these filtration units is relatively poor; The 5th, adsorption unit, it is to utilize porous material, through capillary theory oil is adsorbed onto on the porous material.This adsorption unit, the sorbing material that needs is many, can only adsorb 20Kg oil like one ton of activated carbon, and cost is higher; The 6th, the magnetic resolution device, it is to utilize the cylinder that has magnetic to hold iron filings and iron containing alloy particle in the cutting fluid, but can not dispose the greasy dirt in the cutting fluid.In a word, said apparatus can only be disposed oil slick or the iron filings in the cutting fluid, can't dispose oil in water emulsion, dispersed oil and dissolving oil in the cutting fluid, still can't resolve the putrid and deteriorated problem of cutting fluid.

Summary of the invention

The problem that the present invention will solve provides a kind of cutting fluid purification and uses accurate treatment unit.Adopt this device, can thoroughly solve the putrid and deteriorated problem of cutting fluid, avoid the cutting fluid performance to reduce.

For addressing the above problem, take following technical scheme:

Cutting fluid of the present invention purifies and comprises casing with accurate treatment unit, and its constructional feature is that disengagement chamber and separating barrel are arranged in the casing.Disengagement chamber is a closed cavities, leaves spacing between its top board and roof box.Porose on the top board of disengagement chamber, perforated tube is arranged in the disengagement chamber, the upper end of perforated tube and said hole around between be the sealing shape link together, between perforated tube lower end and disengagement chamber spacing is arranged.Be with filter core on the said perforated tube.Said filter core is a tubulose, its lower end concordant with the perforated tube lower end cover and be the sealing shape link together.Bottom half one side has fluid inlet and sewage draining exit, and fluid inlet is on the sewage draining exit.There are water-purifying cavity and the two connection in the separating barrel lower end, and filter bag and fibrous nodules are arranged in the separating barrel from bottom to top successively, and filtrate is arranged in the filter bag.There is bung the separating barrel upper end, between bung and roof box spacing is arranged, and Y-tube is arranged in the spacing, stretches in the separating barrel after a mouth of Y-tube passes bung, and two mouths are connected to water pipe respectively in addition, and the water pipe lower end all is in the bottom of cabinets cavity.Bottom half one side near separating barrel one side has sewage draining exit and water outlet, and said sewage draining exit is communicated with the cabinets cavity of water-purifying cavity top, and water outlet communicates with water-purifying cavity.Casing top one side near separating barrel one side has oil discharge outlet, and this oil discharge outlet is communicated with cabinets cavity.

Take such scheme, have the following advantages:

Can find out that by such scheme during work, cutting fluid is introduced into the oily water separation chamber,, become oil slick after simultaneously oil in water emulsion being assembled, after cutting fluid is discharged from the oily water separation chamber, discharge from oil discharge outlet again through the filter core breakdown of emulsion in the disengagement chamber.And the cutting fluid behind the breakdown of emulsion gets into separating barrel through Y-tube again, and is through the filtrate in the filter bag that dispersed oil in the cutting fluid and dissolving oil filtering is clean, and clean cutting fluid is finally discharged from water outlet and used.Thoroughly solve the putrid and deteriorated problem of cutting fluid, avoided the reduction of cutting fluid performance.
