Embodiment
Now by reference to the accompanying drawings the specific embodiment of the present invention is described in detail.
As shown in Figure 1, the preparation technology of the PAL material adopted in the present invention mainly comprises the steps, after polygorskite raw ore material disintegrating is obtained polygorskite powder, the stirring that adds water makes polygorskite powder and water fully mix, make the slurry containing polygorskite, then described slurry is introduced solid-liquid cyclone separation device and carry out separating-purifying, get the slurry of overflow port, dehydrate, namely obtain PAL material used in the present invention.
In more detail, after first polygorskite being made powder, adopt 40 ~ 200 orders to sieve, be then 15% ~ 20% add water according to the mass percent of polygorskite, fully stir, i.e. the obtained slurry containing polygorskite.In order to increase the dispersiveness of polygorskite in water, the dispersion agent that mass percent is 3% ~ 8% can be added when adding water, fully stirring, obtained dispersed better containing the slurry of polygorskite.Described dispersion agent can be Tri sodium Phosphate or Sodium hexametaphosphate 99 etc.Preferably, after first polygorskite being made powder, adopting 150 orders to sieve, is then 18% add water according to the mass percent of polygorskite, is 5% add dispersion agent, fully stirs, the obtained slurry containing polygorskite according to the mass percent of dispersion agent.
The speed of rotation of described solid-liquid cyclone separation device is controlled carry out separating-purifying at 2500r/min ~ 3000r/min to the slurry containing polygorskite, secondary or stage trapping purification can be carried out if desired, thus making the PAL material granule particle diameter obtained be 0.1 μm ~ 3.0 μm, purification rate reaches 90%-97%.Wherein median size is the PAL material of 2.69 μm, and particle productive rate reaches 97%, and median size is the PAL material of 0.81 μm, and particle productive rate reaches 50%, and median size is the PAL material of 0.10 μm, and particle productive rate reaches 20%, and maximum particle diameter is 3.0 μm.
The major parts of described solid-liquid cyclone separation device is a conical rotor drum, and diameter increases from inside to outside, and the gradient (semi-cone angle) is 3 ° ~ 5 °, and rotary drum borrows conical floor fixing on center shaft and by electric motor driven rotary.Upper feed mouth and lower feed mouth stretch in rotary drum, and the slurry containing polygorskite is sprayed into by feed mouth, are attached on rotatory drum wall along tangential direction, while drum rotating, along the inclined-plane flowing of drum wall, are formed in the spiralling track in space.Now, slurry stream containing polygorskite is a weak turbulence membrane, when centrifugal force size appropriate amount, can form enough stream change layer thickness and suitable velocity slope, there is effective layering in polygorskite raw ore powder granule, the interlayer repulsion that material grain group produces by shear campaign is loose in stream change layer, gently, heavy material is according to the different transfer relatively of local pressure of self, heavy material proceeds to bottom, and namely the heavy material entering bottom is attached to less movement on bulging wall, and light material enters upper strata.Light material is then at selected velocity of rotation effect low suspension, and its slurry stream is discharged, when heavy material is dipped into certain thickness with higher axial flow velocity by the gap between rotary drum and chassis, stop feed, feed high pressure water by punching material mouth, rinse the heavy material of deposition, realize heavy, light feed separation.High speed centrifugation equipment for purifying belongs to intermittent device, and wherein, feed, wash-down water inject and heavy, light material discharge process automatically runs.
