Description
Technical field
The present invention relates to the screening Magnetic Separation Technology that oil-containing is ground metal dust, and in particular to treatment oil-containing grinding metal
A kind of screening magnetic separator that metal dust is ground for oil-containing of powder.
Background technology
Emergy content can be down to 1.5~1.7%, but still nothing by 3.5% in being ground metal dust by the oil-containing for sieving
Method reaches the impure standard volume of grinding metal dust, it is necessary to further purification.And carried out using the even more thin screen cloth of 150 mesh
If screening, grinding metal dust cannot then sieve.After separating the treatment of cooling machine oil operation, oil-containing grinding metal dust
Surface also sticks micro oil film, and oil-containing grinding metal powder surface shows certain viscosity in the presence of oil film.Therefore,
Under wet conditions, powder particle surface cannot be by screen cloth because of the micro oil film of remaining for oil-containing grinding metal dust；And
In the state of drying, oil-containing grinding most of metal dust in strip helical form and pool pelletizing shape also cannot be by sieve
Net.But oil-containing grinding metal dust has a characteristic, can become loose without pooling pelletizing shape when it runs into water.
The Magnetic Separation Technology of existing oil-containing grinding metal dust is：Directly used without the screening of Wet oscillating screen
Magnetic separator carries out oil-containing grinding metal dust and is separated with emergy.The oil-containing sieved without wet type rotary screen is ground metal powder
End due to the viscous effect of oil film and in strip helical form and pools pelletizing, containing just in the oil-containing grinding metal dust of pelletizing shape
The fine particle for having emergy powder is mingled with.When directly being separated with magnetic separator, the powder of this part pelletizing shape is due to being presented magnetic
Pelletizing and be separated so that influence be ground metal dust impurity content, impure standard volume is not reached far.
The content of the invention
In view of the defect that prior art is present, the present invention using being combined with magnetic separator in wet type rotary screen, can reach sieving,
Magnetic separation is disposably completed.Emergy content is down to less than 0.5% by 3.5% in by magnetic separation oil-containing being made to be ground metal dust, i.e.,
The impure standard volume of grinding metal dust is reached.
To reach above-mentioned purpose, the technical solution adopted in the present invention is that the screening magnetic separation of metal dust is ground for oil-containing
Seperator, it includes that screen cloth, sieve host side steelframe, material sift out material collecting box, frequency modulation motor, sift out material collection agitator tank, sieve
Agitator tank, full counter-current magnetic separator, magnetic separator discharge nozzle are collected in charging；Place screen bed base, sieve master in the sieve host side steelframe top
Machine square steel frame bottom is placed material and sifts out material collecting box, and material sifts out material collecting box side and sets to sift out expects to collect agitator tank, institute
State and frequency modulation motor is set on screen cloth, the feed end of screen cloth sets sieve charging and collects agitator tank；The material that sifts out collects agitator tank company
Full counter-current magnetic separator is connect, magnetic separator discharge nozzle is set on full counter-current magnetic separator.The screen cloth side sets cleaning screen spray group.
Sift out material collection agitator tank and be set to an entirety with full counter-current magnetic separator.
It is preferred that screen cloth is drum-type, frequency modulation motor drives screen cloth to rotate, and the screening of screen cloth is carried out in water.
Screen cloth is alternatively vibration type screen, and frequency modulation motor drives screen bed base vibrations.
Wet type rotary screen is combined with full counter-current magnetic separator, automation screening and magnetic separation is realized, and can will contain oil abrasion
Emergy content is reduced to 0.5% in cutting metal dust, reaches the impure standard volume of grinding metal dust.For this shortcoming,
The present invention utilizes corundum emery dust nonmagnetic and is ground the magnetic principle of metal dust, oil-containing grinding metal dust is first passed through wet
The screening of formula rotary screen carries out full Counter-current wet magnetic separation again, and oil-containing first is ground into metal dust and the screening of emergy powder coarse granule
Go out, then the less emergy powder of particle is excluded by magnetic separation, so as to effectively reduce emergy powder in grinding metal dust
In content.Will wet type rotary screen combined with full counter-current magnetic separator and formed a whole, realize automation screening and magnetic separation,
Time and cost are saved, working strength is reduced.After separating the treatment of cooling machine oil operation, oil-containing grinding metal dust
Surface also sticks micro oil film, and oil-containing grinding metal powder surface shows certain viscosity in the presence of oil film.Therefore,
Under wet conditions, powder particle surface cannot be by screen cloth because of the micro oil film of remaining for oil-containing grinding metal dust；And
In the state of drying, oil-containing grinding most of metal dust in strip helical form and pool pelletizing shape also cannot be by sieve
Net.But oil-containing grinding metal dust has a characteristic, can become loose without pooling pelletizing shape when it runs into water.According to this
Characteristic, takes the design that will be sieved and be put into water and continuously sieve.
The course of work：In the presence of pump, material collects agitator tank and enters screen cloth by sieve charging, and screen cloth is revolved in water
Turn, rotating speed is for 15~20 revs/min and with certain angle of inclination（2~5 °）, the material that sifts out of sieving falls into material and sifts out material collecting box,
Automatic the slipping into inclined-plane for sifting out material collecting box by material sifts out material collection agitator tank, and the material that agitator tank flows out is collected by sifting out material
Magnetic separation is carried out into full counter-current magnetic separator, emergy content is down to by 3.5% in by magnetic separation oil-containing being made to be ground metal dust
Less than 0.5%, that is, reach the impure standard volume of grinding metal dust.
Beneficial effects of the present invention：The present invention utilizes corundum emery dust nonmagnetic and is ground the magnetic principle of metal dust,
And wet type rotary screen is combined with full counter-current magnetic separator, automation screening and magnetic separation are realized, and oil-containing can be ground metal
Emergy content is reduced to 0.5% in powder, reaches the impure standard volume of grinding metal dust.Realize automation screening and
Magnetic separation, low cost and it is easy to operate, reduce working strength, use manpower and material resources sparingly, cleaning screen spray group is set, can carry out automatically clear
Wash, without artificial cleaning.
