The device is easy and convenient to operate, the working strength is low, the automation degree is high, and the oil content of processed metal powder oil-bearing materials is smaller than 1.2%.
Description
Technical field
The invention belongs to and be separated oil-containing metal dust field, specifically relate to a kind of method and the device that are separated oil-containing metal dust.
Background technology
Usually containing oil plant in metal dust, grinding metal dust is exactly wherein a kind of, containing grinding oil in the metal dust of grinding, general oil content is about 15%, grinding metal dust is the byproduct produced with wheel grinding metal works, if do not processed, also just become refuse and be dropped, so just pollute the environment.The metal dust produced during grinding, real density is comparatively large, and metal dust can precipitate down very soon, and seat is real, is unfavorable for automatic transport.
Existing separating metal powder has following three kinds with the method for oil:
First method is artificial reinforced in centrifuge, fluid gets rid of to cavity pocket of outer cover through filter bag gap and drum wall aperture, fluid is discharged by outage, cloth is uneven, and oil plant separative efficiency is low and the rear metal dust oil content of separation is still higher, does not reach the effect of separation, and waste time and energy, working strength is high, cannot realize automated production, and oil removal rate is extremely low.
Second method is heating means, and be placed in a large still by metal dust and oil plant and add water, electricity consumption or other mode of heatings heat it, and oil gently can swim on water surface, come separating oil and metal dust.This method oil plant is separated not thorough, and operation is heavy, and floor space is large, and labour intensity is high.
The third method is lighted by the metal dust containing oil plant, burns the rear Footwall drift powder of oil.The a large amount of smoke pollution environment of this method combustion release, due to high-temperature metal Powder Oxidation, metal recovery rate is low.
Summary of the invention
In order to solve prior art Problems existing, the invention provides a kind of method and the device that are separated oil-containing metal dust.
Be separated a method for oil-containing metal dust, in oil-containing metal dust, add water, the oil-containing metal dust adding water is carried out centrifugation, under the influence of centrifugal force, oil is extruded by water, and oil displaces by the position that water occupies oil, forms moisture metal powder layer, water layer and oil reservoir.Oil-containing metal dust is oil-containing grinding metal dust.Oil-containing metal dust carries out pretreatment, in oil-containing metal dust, add oil, and slurry is carried out centrifugal treating by furnishing slurry oil, isolates part oil.The oil phase of the oil added in oil-containing metal dust and oil-containing metal dust itself is same.
A kind of device being separated oil-containing metal dust, comprise centrifuge, feed pipe, shurry pump, paddle, size mixing tank and buncher, feed pipe one end extend in centrifuge, the feed pipe other end is connected with shurry pump, shurry pump is connected with tank of sizing mixing, paddle is arranged in tank of sizing mixing, and paddle upper end connects buncher.Also comprise pipette and suction pumps, pipette one end extend in centrifuge, and the pipette other end connects suction pumps.Arrange cloth bag in bowl, oil-containing metal dust loads in cloth bag, is separated.The rotary drum of centrifuge is vertical.
Separated from metal dust by oil with centrifugal device, its principle is that the proportion of water is more great than the ratio of oil, under the influence of centrifugal force, centrifugal force suffered by water is larger than the centrifugal force suffered by oil, therefore water will occupy the position of oil, is extruded by oil, reaches the object being separated oil-containing metal dust.
Adopt oil to make diluent, oil and metal powder in certain ratio are arranged in pairs or groups, and make metal dust form fluid state, so just can be squeezed in the device of process material by metal dust thing to be processed with pump, realize the process of automated production.
Add the method for pretreating process process: oil and oil-containing metal powder in certain ratio are added to and size mixing in tank, the ratio of being adjusted to is that oil accounts for 35 ~ 55%, and metal dust accounts for 65 ~ 45%, is stirred by paddle, make oil and metal dust Homogeneous phase mixing, have certain mobility.The slurry that this method adjusts is placed and also can not be precipitated for 12 hours, is convenient to shurry pump conveying.The oil-containing metal dust regulated; be transported in the device of the separation oil-containing metal dust of certain rotating speed (rotating speed about 200 revs/min) with shurry pump; when slip is even; stop charging; improving rotary drum rotating speed is 2300 ~ 3000 revs/min; start oil plant to be separated; during shutdown; metal dust can be close on drum inner wall cloth bag; unnecessary oil is just separated, and oil accumulates in cloth bag bottom bowl, and pipette is advanced oil reservoir position by propeller under compressed air effect; by pipette by oily sucking-off, reach separation object.In centrifuge, add water again, improve centrifuge speed and be about 200 revs/min, centrifuge inner chamber rotary drum when rotated, can keep apart by water by oil and metal dust.When rotary drum stops operating, the grinding metal dust in centrifuge is close on drum inner wall cloth bag, and water and replaced oil out amass in bottom of the drum, reach separation object.Afterwards by twice propelling of pipette, first by oily sucking-off, then by water sucking-off.
There is no the method for pretreating process process: in oil-containing metal dust, add water, carry out centrifugal, rotating speed about 200 revs/min, when rotary drum stops operating, metal dust in centrifuge is close on drum inner wall cloth bag, and water and the oil separated amass in bottom of the drum, reach separation object.Afterwards by twice propelling of pipette, first by oily sucking-off, then by water sucking-off.
The invention has the beneficial effects as follows
:make carrier with oil and regulate metal dust good stability, place and also can not precipitate for 12 hours, the fluidity of slurry of conciliation is good, owing to there being oil, also playing lubrication, prevents pump shaft from wearing and tearing, can extend the service life of shurry pump in stock transport process.Use water as replacement media, oil can reclaim use, and can not make the raw qualitative change of fry dried food ingredients, the water of displacement can need not be drained by Reusability, affects environment.Can carry out automated production, reduce labour, output fluctuation is little.Equipment operating is easy, and cost is low, can reduce used manpower and material resources, working strength is low, automaticity is high, metal dust after process is less than 1.2% containing the oil content in oil plant.
