In embodiments of the present invention 3, the mixing ratio of having put down in writing the mixture of the charged particle that becomes the selection object is not the picking method that waits simultaneously.The mixing ratio of actual charged particle is not that situation about being equal to is more, if the mixing ratio of positively charged particle and electronegative particle is offset to one party, then produces difference when making particle by frictional electrification in carried charge.In addition, if the mixing ratio that is 1: 4 as positively charged particle 31 and the electronegative particle 32 of proportion 1, particle diameter 3mm, then the carried charge with respect to positively charged particle 31 is+0.6nC, the carried charge of electronegative particle 32 becomes-0.15nC about.
Fig. 3 is the structure skeleton diagram of the electrostatic sorting apparatus of conventional art.As shown in Figure 3, it is that interval with 10cm is oppositely arranged that the earth electrode 1 of width 8cm and high pressure apply electrode 2, and the separated space that separates 60cm downwards from two electrodes arranges positively charged particle returnable 61 and electronegative particle returnable 62.High pressure applies electrode 2 and is connected with high voltage source 5, is applied in the voltage of 40kV, between two electrodes electrostatic field occurs.At this moment, if make the mixture that is consisted of by charged particle by charged passing through afterwards in the electrostatic field such as stirrings, then positively charged particle 31 and earth electrode 1 collision, and be attached to earth electrode 1, perhaps rebound to a side of electronegative particle returnable 62, so the selection precision step-down of mixture.In addition, till electronegative particle 32 arrives returnable during to attracted to the displacement that high pressure applies the horizontal direction of electrode 2 sides by electrostatic force be about 9cm.
Fig. 4 is the structure skeleton diagram of the electrostatic sorting apparatus of embodiments of the present invention 3.Be with the discrepancy of the sorting plant in the past of Fig. 3, electrode is made as netted earth electrode 11 and netted high pressure applies electrode 21, is provided with for what apply electrode 21 side generation air streams 41 along the direction parallel with electrostatic field from the netted high pressure of netted earth electrode 11 side direction in netted earth electrode 11 sides and send exhaust apparatus 7.Particularly, as shown in Figure 4, it is that interval with 10cm is oppositely arranged that the netted earth electrode 11 of width 8cm (the first electrode) and netted high pressure apply electrode 21 (the second electrode), becomes the path that falls of selection object between two electrodes.In addition, the separated space that separates 60cm downwards from two electrodes is provided with positively charged particle returnable 61 and electronegative particle returnable 62, is provided with for sending exhaust apparatus 7 along the direction generation air stream 41 parallel with electrostatic field in netted earth electrode 11 sides.Netted high pressure applies electrode 21 and is connected with high voltage source 5, is applied in the voltage of 40kV, between two electrodes electrostatic field occurs.In addition, the first electrode and the second electrode also can be that netted earth electrode 11 and netted high pressure apply any one in the electrode 21.
In addition, if the flow velocity of air stream 41 is made as 5.8m/s, then positively charged particle 31 is suppressed with the phenomenon of netted earth electrode 11 collisions, simultaneously electronegative particle 32 attracted to the displacement that netted high pressure applies the horizontal direction of electrode 21 sides becomes about 20cm, chooses as can be known ratio of precision sorting plant in the past and improves.
Thus, can suppress by the selection object in the electrostatic field and the phenomenon of electrode collide.
In addition, in embodiments of the present invention 3, used air stream 41, even but replace air stream 41 and the air-flow of use nitrogen or other gases, same effect also obtained.
(embodiment 4)
Fig. 5 is the structure skeleton diagram of the electrostatic sorting apparatus of embodiments of the present invention 4.Embodiments of the present invention 4 are characterised in that, for to the electrostatic field that produces between the electrode and be positioned at two electrodes below separated space along the direction generation air stream that provides the resistance of gravity, and along parallel direction generation air stream, and configuration is along the exhaust apparatus that send of separately direction generation air stream to electrostatic field.
As shown in Figure 5, it is that interval with 10cm is oppositely arranged that the netted earth electrode 11 of width 8cm (the first electrode) and netted high pressure apply electrode 21 (the second electrode), becomes the path that falls of selection object between two electrodes.In addition, the separated space 77 that separates 60cm downwards from two electrodes disposes reticular zone positive electricity particle returnable 63 and reticular zone negative electricity particle returnable 64.Netted high pressure applies electrode 21 and is connected with high voltage source 5, is applied in the voltage of 40kV, between two electrodes electrostatic field occurs.In addition, send exhaust apparatus 7 what netted earth electrode 11 sides were provided for applying along the direction parallel with electrostatic field from the netted high pressure of netted earth electrode 11 side direction electrode 21 side generation air streams 41, and then below netted returnable, arrange and send exhaust apparatus 71 to electrostatic field and separated space along providing direction to the resistance of gravity that second of the second air stream 42 occurs.In addition, the first electrode and the second electrode also can be that netted earth electrode 11 and netted high pressure apply any one in the electrode 2.
In sorting plant in the past shown in Figure 3, if make the mixture that is consisted of by the positively charged particle 31 after charged and electronegative particle 32 by in the electrostatic field, then positively charged particle 31 and earth electrode 1 collision, attracteding to the displacement that high pressure applies the horizontal direction of electrode 2 sides by electrostatic force during till electronegative particle 32 arrives returnable is about 9cm.
Relative with it, in the electrostatic sorting apparatus of embodiments of the present invention 4, if for example the flow velocity of air stream 41 is made as 5.8m/s, the flow velocity of the second air stream 42 is made as 7.5m/s, then positively charged particle 31 is suppressed with the phenomenon of netted earth electrode 11 collisions, and till arriving returnable during to the about 28cm of netted earth electrode 11 side shiftings, electronegative particle 32 till arriving returnable during apply the about 24cm of electrode 21 side shiftings to netted high pressure.Therefore, can consist of the electrostatic sorting apparatus that to realize the selection under the abundant high accuracy.
Thus, the time of selection object by electrostatic field is than prolonging in the past, so the selection precision improves, can be reduced to the selection precision that obtains and be equal in the past and required voltage.And then, can suppress by the selection object in the electrostatic field and the phenomenon of electrode collide.
In addition, in embodiments of the present invention 4, used air stream 41, even but replace air stream 41 and the air-flow of use nitrogen or other gases, same effect also obtained.
More than describe the present invention in detail, but above-mentioned explanation only is an example, and the invention is not restricted to above-mentioned explanation.Can not depart from the scope of the present invention and obtain not illustrative countless variation.
