Embodiment
Consult Fig. 1 and 2 now, solid separator 1 of expression among the figure, it comprises a fluid inlet 2 and two fluid outlets 3,4.Solid separator 1 comprises that also a whirlpool causes part 5, and any solid that it carries in the fluid that flows through separator before fluid enters rotary shell 6 gives radially outer power.Whirlpool causes that part 5 comprises impeller 7,8, and described impeller is installed on the central shaft 9 that extends on separator 1 central axis.Central shaft 9 rotates by a motor or other appropriate device, and described motor also rotates rotary shell 6 by the connection via the supporting blade on the central shaft 9 10.
The fluid initial whirlpool of borrowing before entering rotary shell 6 that enters separator 1 causes part 5 with the circus movement rotation, and the particle that carries in the fluid stream in rotary shell 6 is shifted to the internal surface of rotary shell 6.Because there is minimum turbulence level in housing 5 according to the circular frequency rotation similar to fluidic circular frequency when fluid flows through separator, fluid flows with layer flow mode basically.Fluid stream is divided into outer section part and interior profile part by the tubular separator 11 that is positioned at rotary shell 6.Then, interior profile partly is drawn towards filtrate outlet 3, contains the outer section of the spissated particulate that is carried and partly is drawn towards solid outlet 4.
Consult Fig. 3 and 4 now, expression is according to sampling unit 21 of the present invention among the figure.Device 21 generally is placed in the fluid mixture that contains the solid fluid that carries and/or different densities, wherein needs a kind of sample with special component of specific gravity.
Device 21 comprises a central shaft 22 on the central axis that is positioned at device 21.This axle is installed on the rotary shell 23 by guide card 24, also is installed in whirlpool and causes on the impeller 25.Axle 22 is by motor or 26 rotations of other appropriate device, and it rotates rotary shell again and whirlpool causes impeller.
Be placed in the fluid mixture and collected specimens by installing 21, wherein fluid is drawn into device 21 in import 27.When fluid flowed into rotary shell 23, fluid caused that by whirlpool impeller 25 rotates with circus movement at first.Owing in fact do not have a turbulent flow, and fluid flows through with layer flow mode substantially, thereby fluidic circular frequency is divided into the transverse section stream of fluid mixture in the zone of different densities.The bigger region adjacent of density is in rotary shell 23, and lighter region adjacent is in central shaft 22.Then, use a pipette collection to have the sample in the zone that needs fluid density in the outlet of device, all the other fluids that flow through are drawn towards outlet 29.
Consult Fig. 5 to 9 now, the solid separator of expression enerally designated 50 among the figure, this solid separator comprises a fluid inlet 51 and two fluid outlets 52 and 53.This separator comprises that also a whirlpool causes device 54, and this whirlpool causes device before fluid enters runner between inner rotary shell 55 and the outside rotary shell 56, and any solid that carries in the fluid that flows through separator 50 revolves and adds radially outer power.Whirlpool causes that device 54 is arranged on the outside surface of an inversion bell-shaped piece, and this inversion bell-shaped piece is installed on the periphery of inner shell 57.Whirlpool causes that device is the impeller form along the bell-shaped piece outside surface, and its structure not only applies a radially outer power to fluid, and has lifting or automatic pumping effect, and fluid is sent into runner 58.A central shaft 60 makes whirlpool cause that device and inside and outside housing 55 and 56 rotate.Central shaft 60 generally rotates by motor or other appropriate device.
The fluid that enters separator 50 causes that by whirlpool device 54 begins rotation and rises up into runner 58.In case enter runner 58, inner rotary shell 55 and outside rotary shell 56 keeps the fluidic circular frequency, thereby the particle that carries in the fluid is shifted to the peripheral part in the transverse section of the internal surface of outside rotary shell 56 or runner 58.Because inside and outside housing 55,56 rotates according to the speed similar to fluidic circular frequency, thereby exists minimum turbulence level when fluid flows through separator 60, fluid flows with layer flow mode substantially.Fluid stream is separated in outlet 52 and 53.Thereby the tubular separator 59 that vertically is installed between inner shell 55 and the outer hull 56 52 is limited to second outlet between tubular separator 59 and the outer hull 56, and first outlet 53 is limited between tubular separator 59 and the inner shell 55.Arrive first and second outlets 52 and at 53 o'clock at fluid, the fixing peripheral part that has moved to the transverse section of stream that carries, thus shift out separator via second outlet 52.Fluidic rest part or filtrate flow out separator via first outlet 53.Tubular separator also can be rotated by central shaft 60.
Consult Fig. 8 now, the A-A section among the figure in the presentation graphs 7.This section is represented from the outlet position 63 of the separator of first outlet 53.Fluid or filtrate move up between tubular separator and inner shell, enter outlet position 63 until back-out.Consult Fig. 9 now, the B-B section among the figure in the presentation graphs 7.This section is represented from the outlet position 64 of the separator of second outlet 52.Spissated solid moves up between tubular separator 59 and outer hull, enters outlet position 64 until back-out.
Consult Figure 10 now, more detailed expression whirlpool causes device 54 among the figure, and this whirlpool causes that device is the impeller form, is arranged on the outside surface of an inversion bell-shaped piece 65.The shape of impeller 54 makes that it provides certain lifting degree or automatic pumping effect to the fluid of process when rotating, and rotation.
Figure 11 represents that whirlpool causes device 54 and the inversion bell-shaped piece 65 that makes up with the import of separator 51.Inner rotary shell is provided with to such an extent that flush with surface 68 usually.
Though several preferred embodiment have been described in detail in detail,, those skilled in the art obviously can carry out various variations, substitutes and revises and do not deviate from spirit of the present invention or exceed scope of the present invention.
