Description
Technical field
The invention belongs to rotary screen technical field, specifically relate to a kind of wet type rotary screen sieving oil-containing grinding metal dust.
Background technology
After being separated the operation process of oil-containing metal dust, 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 causes grinding metal dust to form bulk or rolls into a ball spherical and cannot pass through screen cloth because of the oil film of remaining trace oil-containing grinding metal dust; And under the state of drying, oil-containing grinding metal dust great majority go into bulk or caking owing to there being oil film to exist equally, screen cloth cannot be passed through.
Existing triage techniques has two kinds.The first is after sieve is put into water, manually rocks sieve and screens.The second adopts Wet oscillating screen, and the material that sieve is put into sieve, opens vibratory sieve, and the material on sieve is block spherical with group owing to being formed very soon under the effect of micro oil, cannot sieve.Above two kinds of methods, waste time and energy, working strength is high, automaticity is low, and sieving rate are extremely low.
Summary of the invention
The present invention mainly solves the coarse granule (being greater than 0.5mm) in oil-containing grinding metal dust and the emery wheel emergy in oil-containing grinding metal dust.Under dampness and drying regime, coarse granule and emery wheel emergy are all difficult to separate from oil-containing grinding metal dust, for this reason, the invention provides a kind of wet type rotary screen sieving oil-containing grinding metal dust, carry out the purification of grinding metal dust, reduce the manpower and materials of use, working strength is low, automaticity is high, sieving rate is high.
The wet type rotary screen of screening oil-containing grinding metal dust, it is characterized in that: comprise screen cloth, screen bed base, sieve main frame square steel frame, material screen discharging collecting box, first frequency modulation motor, sift out material and collect agitator tank and sieve charging collection agitator tank, screen cloth is arranged on screen bed base, in sieve main frame square steel frame, material screen discharging collecting box is set, above sieve main frame square steel frame, screen bed base is set, screen bed base is horizontal cylinder shape, screen bed base one end connects the first frequency modulation motor, first frequency modulation motor drives screen bed base to rotate, at the screen bed base other end and material screen discharging collecting box side arrange sieve charging collect agitator tank, arrange in any in addition side of material screen discharging collecting box and sift out material collection agitator tank, water is added in material screen discharging collecting box inside, screen bed base rotates in water.Screenings is set in material screen discharging collecting box and collects chute, screenings is collected and sifts out in material collection agitator tank, oversize is set in material screen discharging collecting box and collects chute, material is collected agitator tank from sieve charging and collects in screen cloth.Screen bed base is obliquely installed, and angle of inclination is 2 ° to 5 °.Screen bed base side arranges cleaning screen spray group.Material screen discharging collecting box inner upper arranges drainpipe.Sieve charging is collected above agitator tank and is arranged the second frequency modulation motor, sifts out above material collection agitator tank and arranges the 3rd frequency modulation motor.Sift out material collection agitator tank and sieve charging collection agitator tank inside interpolation water, add the height of water and the same height of water of material screen discharging collecting box inside.
Oil-containing grinding metal dust after being separated the operation process of oil-containing metal dust, although the oil also containing trace is wrapped on the surface of particle, but there is a characteristic in oil-containing grinding metal dust, the spherical body of the agglomerate formed when it runs into water or formation can become loose, does not pool pelletizing or bulk.According to this characteristic, take sieve to put into water and the design of sieving continuously, after an endfeed, sieve is rotated in water, the material that sieve is in water always, keep loose condition (of surface).So just be easy to purify to oil-containing grinding metal dust.
Oil-containing grinding metal dust is joined sieve charging and collect agitator tank, add water, stirred, after stirring by the second frequency modulation motor, screen bed base one end is expected with pumping, drive central shaft that sieve is rotated in water by the first frequency modulation motor, rotating speed is 15 ~ 20 revs/min and is with 2 ° ~ 5 °, certain angle of inclination, and material is driven in water sieve, grinding metal powder material just starts to be in water always, non-agglomerate laxity is good, keeps loose condition (of surface), easily sieves.Oversize is oarse-grained emery wheel particle, is discharged by the screen bed base other end; Screenings is grinding metal dust and minority granule emery wheel particle, is entered sift out material collection agitator tank by screenings collection chute.The material sieved, under agitator effect, can be squeezed into subsequent processing with shurry pump by the material in each collecting tank.
The invention has the beneficial effects as follows: the present invention is easy and simple to handle, the material sieved is in water always, does not form bulk or spherical, remain loose condition (of surface), be conducive to sieving.Expense is low, reduce use manpower and materials, working strength is low, automaticity is high, sieving rate is high.Carry out emergy content in the oil-containing grinding metal dust sieved through water sieve and can be down to 1.5% ~ 1.7% by 3.5%.
