Show that as Fig. 2 is detailed cylinder 103 is made of with following straight portion 162 last wide last tapering 161.Tapering 161 and straight portion 162 respectively by bearing 163,164 be supported on the rotary body roof 122 with rotary body diapire 123 on.The handled thing that is provided with vertical rectangularity in straight portion 162 is by hole 165.Handled thing passes through hole 165 when the inboard, and is relative with the outlet 157 of ingress pipe 156.
In straight portion 162, upper and lower settings multilayer baffle plate 166.Show that as Fig. 3 is detailed baffle plate 166 is things of horizontal semicircle shape.Neighbouring baffle plate 166 overlapping respectively whole plate 2/3.
Secondary driven sprocket 183 is being fixed in lower end, 161 outside in the tapering.As shown in Figure 4, volume is hung chain 184 on secondary drive sprocket 182 and secondary driven sprocket 183.
Make main motor 171 work, rotary body 102 is that rotate at the center with its rotating shaft 121, and along with the rotation of rotary body 102, cylinder 103 is around the axis revolution of rotating shaft 121.On the other hand, make auxiliary motor 181 work, chain 184 is moved, thus, 4 cylinders 103 are simultaneously respectively around himself axis rotation.
The revolution speed of cylinder 103 is suitably set according to the former water-based shape that separates.As, the peripheral speed of the revolution speed of cylinder 103 can be set at 500～1000m/min.If the radius of gyration of revolution is about 400mm, then revolution speed is 600rpm.
As shown in Figure 5, the revolution of cylinder 103 moves continuously.Therebetween, borrow to pump open/stop transport commentaries on classics, former water is supplied to off and on.Its interval, such as being supply in 1 minute, 1 minute stops supplying.During former water was supplied with, the rotation of cylinder 103 stopped, and handled thing is by the radius of gyration inboard of hole 165 towards revolution.During former water stopped supplying, 103 of cylinders changeed 1 time, therefore, transferred towards the outside, then again towards the inboard by hole 165 towards the handled thing of inboard originally.The rotation of cylinder 103 begins, and can stop for simultaneously with former water, also can be after Yuan Shui stops for the process official hour.The rotation of cylinder 103 can be changeed 360 ° continuously; Also can Rotate 180 ° stop, having stopped after the stipulated time, change 180 ° to opposite direction.
Shown in Fig. 6 (a), under the relative state of the handled thing of cylinder 103 outlet 157 by hole 165 and ingress pipe 156, by supply pipe 153 former water B is supplied with distributor chamber 141, the former water B that the is supplied with centrifugal force that 102 revolution produce by rotary body is attached on the side face of distributor chamber 141, discharges from its outlet 157 by ingress pipe 156.From exporting the 157 former water B that discharge, borrow that same action of centrifugal force is further quickened, straight line flies to stride, flow in the cylinders 103 by hole 165 by handled thing.Because former water B straight line flies to stride, even between the outlet 157 edge portions of the handled thing of cylinder 103 by hole 165 edge portions and ingress pipe 156 a little gap is arranged, former water B can not overflow from this gap location yet.
After former water B imported in the cylinder 103, through the stipulated time, former water B promptly was separated into solid content D and moisture W, and moisture W discharges from the upper end open of cylinder 103; Shown in Fig. 6 (b), when cylinder 103 is turned over after 180 °, the solid content D that separates promptly discharges from cylinder 103 by hole 165 by handled thing.
Refer again to Fig. 7～10, other variation about centrifugal separating device are described.The essential structure of the centrifugal separating device of this variation, identical with the structure of the centrifugal separating device shown in Fig. 1～6.
As Fig. 7 and shown in Figure 8, multilayer insulating panel 201 up and down is being set in cylinder 103.Dividing plate 201 and said baffle 166 have identical shaped, one-tenth level semicircle.Be piled up configuration but all dividing plates 201 are whole respectively.Handled thing by hole 165 under the state of inboard, dividing plate 201 has occupied the semi-circular portions by hole 165 relative sides of butt handled thing on cylinder 103 cross sections; The top end face of dividing plate 201 with respect to handled thing by hole 165, with the inward-outward direction quadrature.
Bottom illustrates separating action with reference to Fig. 9 and Figure 10.
Shown in Fig. 9 (a), handled thing passes through hole 165 when inboard, cylinder 103 stalls, and former water B supplies with cylinder 103.Near the height of the undermost dividing plate 201 of supply water level of former water B.The former water B that is supplied with, in cylinder 103, produce upwelling by revolution centrifugal force, arrive its upper strata dividing plate 201, surmount dividing plate 201 one by one from undermost dividing plate 201, but supply with the amount of former water B in periodic duty, be set at the dividing plate 201 (with reference to Fig. 7) that does not surmount the superiors.Like this, below the superiors' dividing plate 201, be detained the former water that a periodic duty is supplied with.
As shown in Figure 7, be trapped in the former water B of the superiors' dividing plate 201 belows, before cylinder 103 beginning rotations, during cylinder 103 stopped rotation, solid content D separated fully with moisture W.
Shown in Fig. 9 (c), cylinder 103 1 turns over 90 °, and its rotation was once interrupted.This rotation required time is shorter, and since the adhesion strength of isolated solid content D and moisture W in other words owing to the difference of both flowabilities, owing to the moisture W that separated by centrifugal action along with the rotation of cylinder 103 changes moving of its position constantly, moisture W discharges from cylinder 103.Owing to terminate in the original place, solid content D is attached to the inner face of cylinder 103 and remains in the cylinder 103.
After cylinder 103 turned over 90 °, through the stipulated time, the rotation of cylinder 103 began once again.Shown in Fig. 9 (d), after rotation begins again, change 90 ° again as cylinder 103, handled thing passes through the hole toward the outer side, and the solid content D that is subjected to centrifugal action discharges by hole 165 from the handled thing that becomes toward the outer side.
In the present embodiment, be to make whole former water become the state that is stranded in the cylinder of resting state to implement separating action down, this point is the difference with the previous embodiment maximum.In the aforementioned embodiment, former water is supplied with in the cylinder, and with the separating action while, the moisture of separating is discharged one by one from the cylinder upper end.Like this, when being subjected to centrifugal action, treatment fluid one moves, owing to together contain solid content in the moisture that moves, and probably separating power will descend.In order to improve separating power, if strengthen centrifugal force, then the moisture power that will take away solid content also becomes greatly, even strengthen centrifugal force again, also is difficult to expect the raising of separating power.This point, in the present embodiment because in the separating action, former water in cylinder by static down, so be expected to obtain separating power than higher.
Bottom with reference to Figure 11～17, describes with regard to another variation of centrifugal separating device.
With reference to Figure 11, in the centrifugal separating device of this variation, be to have replaced dividing plate 201 in the cylinder shown in Figure 7 103 with filtration members 211.Filtration members 211 handled thing by hole 165 directly over, become horizontal circle tabular, covered the whole upper end open of cylinder 103.
As shown in figure 12, filtration members 211 is made by the thing that is called wedge-section wire (ゥ エ Star ジ ヮ ィ ャ-), and has shape path 221 arranged side by side.Pass through hole 165 under the state of revolution center at handled thing, the length direction of path 221 is towards the radial direction of revolution.Show the cross-sectional outling wedgewise of path 221 as Figure 15 is detailed.The lower end minimum widith C of path 221 has only about 30 μ m.
During making rotary body 102 revolution, by the state of hole 165 towards the inboard, the outlet 157 by ingress pipe 156 infeeds former water that (see Figure 13 a), the former hydropexis that infeeds is at the downside of filtration members 211 in the cylinder 103 at handled thing.Because the centrifugal force of revolution is stranded in the former water of filtration members 211 downsides, very fast moisture separates with solid content, and in the moisture that has separated and the solid content, moisture is by the upper end open discharge (see Figure 13 b) of filtration members 211 from cylinder 103.On the other hand, solid content can't pass filtration members 211, still under its downside is detained (seeing Figure 13 c).Expected moisture from the time that cylinder 103 has been discharged, made cylinder 103 rotations.Therefore, handled thing becomes toward the outer side state by hole 165 from the state towards the inboard, but in the present embodiment, but also image pattern 7～10 illustrated embodiments are such, needn't make cylinder 103 in the rotation Halfway Stopping.Handled thing becomes toward the outer side state by hole 165 1, because the centrifugal force of rotary body 102 revolution, solid content is promptly peeled off from cylinder 103 inner faces, from cylinder 103 through handled things by hole 165 discharges (seeing Figure 13 d).Then, make once again handle by hole 165 towards inboard, supply with treatment fluids to cylinder 103 and get final product.The timetable of above-mentioned separating action is illustrated on Figure 17.
Show as Figure 14 is detailed, when separating action begins, the whole solid content that adhering to of the part that contacts with treatment fluid of filtration members 211, the part of moisture by portion that become in filtration members 211 also is attached with solid content, but because of action of centrifugal force, the solid content that adheres to presses against the outside of this moisture by portion, needn't worry that therefore solid content stops up this moisture by portion, and the moisture of separating can pass through portion by above-mentioned moisture smoothly.
On Figure 16, show and filtration members is divided into 2 layers example.At this moment, the filtration members 231 of downside is carried out coarse filtration; The filtration members 232 of upside is carefully filtered, and 231,232 of two filtration members leave the gap.
In addition, as in 1 cylinder, filtration members being divided into 2 layers alternative form, also centrifugal separating device itself can be divided into 2 sections.At this moment, in the upstream side centrifugal separating device, use the coarse filtration part; And in the centrifugal separating device of downstream, use thin filtration members.
The gap of filtration members 232 is promptly effective about 5～50 μ m.The material of filtration members except that above-mentioned wedge-section wire, is gone back available metal net, cloth, nylon fiber, pottery etc.
Even in this variation, also can use the baffle plate and the dividing plate that use in the aforementioned variation.
More than the separating action of liquid is illustrated, but based on basic principle of the present invention, not only to liquid, also applicable to the separating action of gas.At this moment, based on the proterties difference of liquid and gas, be necessary above-mentioned centrifugal separating device is done some design alteration.As the conveying mechanism of gas, the sealing mechanism of gas etc.
