Description
Technical field
The present invention relates to the screening Magnetic Separation Technology of oil-containing grinding metal dust, be specifically related to a kind of screening magnetic separator for oil-containing grinding metal dust processing oil-containing grinding metal dust.
Background technology
In the oil-containing grinding metal dust of screening, emergy content can be down to 1.5 ~ 1.7% by 3.5%, but still cannot reach the impure standard volume of grinding metal dust, needs to purify further.And adopting the even thinner screen cloth of 150 orders to carry out sieving, grinding metal dust then cannot sieve.After being separated the process of cooling machine oil operation, oil-containing grinding metal powder surface is the glutinous oil film having trace also, and under the effect of oil film, oil-containing grinding metal powder surface presents certain viscosity.Therefore, under wet conditions, powder particle surface cannot pass through screen cloth because of the oil film of remaining trace to oil-containing grinding metal dust; And under the state of drying, oil-containing grinding metal dust great majority are in rectangular helical form and pool pelletizing shape and also cannot pass through screen cloth.But oil-containing grinding metal dust has a characteristic, can become loose when it runs into water and not pool pelletizing shape.
The Magnetic Separation Technology of existing oil-containing grinding metal dust is: without the screening of Wet oscillating screen and direct magnetic separator carries out being separated of oil-containing grinding metal dust and emergy.Without the oil-containing grinding metal dust of wet type rotary screen screening due to the viscous effect of oil film and in rectangular helical form pool pelletizing, containing just having the fine particle of emergy powder to be mingled with in the oil-containing grinding metal dust of pelletizing shape.When direct magnetic separator is separated, the powder of this part pelletizing shape is separated owing to presenting magnetic pelletizing, thus affects the impurity content of grinding metal dust, does not far reach impure standard volume.
Summary of the invention
In view of the defect that prior art exists, the present invention adopts and is combined with magnetic separator at wet type rotary screen, can reach sieve, magnetic separation is disposable completes.Emergy content in oil-containing grinding metal dust can be made to be down to less than 0.5% by 3.5% through magnetic separation, namely reach the standard volume that grinding metal dust is impure.
For achieving the above object, the technical solution adopted in the present invention is the screening magnetic separator for oil-containing grinding metal dust, and it comprises screen cloth, sieve main frame square steel frame, material screen discharging collecting box, frequency modulation motor, sifts out material collection agitator tank, sieve charging collection agitator tank, full counter-current magnetic separator, magnetic separator discharge nozzle; Screen bed base is placed on described sieve main frame square steel frame top, material screen discharging collecting box is placed in sieve main frame square steel frame bottom, material screen discharging collecting box side is arranged sifts out material collection agitator tank, and described screen cloth arranges frequency modulation motor, and the feed end of screen cloth arranges sieve charging and collects agitator tank; The described material collection agitator tank that sifts out connects full counter-current magnetic separator, full counter-current magnetic separator is arranged magnetic separator discharge nozzle.Described screen cloth side arranges cleaning screen spray group.
Sift out and expect that collection agitator tank and full counter-current magnetic separator arrange as a whole.
Preferred screen cloth is drum-type, and frequency modulation motor drives screen cloth to rotate, and the screening of screen cloth is carried out in water.
Screen cloth also can be vibration type screen, and frequency modulation motor drives screen bed base vibrations.
Wet type rotary screen is combined with full counter-current magnetic separator, realizes automation screening and magnetic separation, and emergy content in oil-containing grinding metal dust can be reduced to 0.5%, reach the standard volume that grinding metal dust is impure.For this shortcoming, the present invention utilizes emergy powder nonmagnetic and the magnetic principle of grinding metal dust, oil-containing grinding metal dust is first carried out full Counter-current wet magnetic separation again through the screening of wet type rotary screen, first oil-containing grinding metal dust and emergy powder coarse granule are sieved out, again emergy powder less for particle is got rid of by magnetic separation, thus effectively reduce the content of emergy powder in grinding metal dust.To be combined with full counter-current magnetic separator by wet type rotary screen and to form a whole, achieve automation screening and magnetic separation, save time and cost, reduce working strength.After being separated the process of cooling machine oil operation, oil-containing grinding metal powder surface is the glutinous oil film having trace also, and under the effect of oil film, oil-containing grinding metal powder surface presents certain viscosity.Therefore, under wet conditions, powder particle surface cannot pass through screen cloth because of the oil film of remaining trace to oil-containing grinding metal dust; And under the state of drying, oil-containing grinding metal dust great majority are in rectangular helical form and pool pelletizing shape and also cannot pass through screen cloth.But oil-containing grinding metal dust has a characteristic, can become loose when it runs into water and not pool pelletizing shape.According to this characteristic, take sieve to put into water and the design of sieving continuously.
The course of work: under the effect of pump, material enters screen cloth by sieving charging collection agitator tank, screen cloth is rotated in water, rotating speed is 15 ~ 20 revs/min and is with certain angle of inclination (2 ~ 5 °), the material that sifts out sieved falls into material screen discharging collecting box, automatically slipped into by the inclined-plane of material screen discharging collecting box and sift out material collection agitator tank, enter full counter-current magnetic separator by the material sifting out the outflow of material collection agitator tank and carry out magnetic separation, emergy content in oil-containing grinding metal dust can be made to be down to less than 0.5% by 3.5% through magnetic separation, namely the standard volume that grinding metal dust is impure is reached.
Beneficial effect of the present invention: the present invention utilizes emergy powder nonmagnetic and the magnetic principle of grinding metal dust, and wet type rotary screen is combined with full counter-current magnetic separator, realize automation screening and magnetic separation, and emergy content in oil-containing grinding metal dust can be reduced to 0.5%, reach the standard volume that grinding metal dust is impure.Achieve automation screening and magnetic separation, cost low and easy and simple to handle, reduce working strength, use manpower and material resources sparingly, cleaning screen spray group is set, can automatically cleans, without the need to manual cleaning.
