Specific embodiment
The present embodiment is a kind of dynamical water-oil separating duplex centrifugal machine.
Refering to fig. 1~Fig. 3, the dynamical water-oil separating duplex centrifugal machine of the present embodiment, by centrifuge cavity 6, drive shaft
8, drive shaft fixing piece 9, rotatory 10, big-taper-angle taper segment 12, overflow segment 13 and motor 1 form；Centrifuge cavity 6 and big cone angle
Cone section 12, overflow segment 13 are fixed with one structure, oil outlet 3, liquid inlet 4 are respectively equipped on centrifuge cavity 6, overflow segment 13 is set
There is water outlet 5, oil outlet 3 and oil sump tank are connected.Motor 1 is mounted on the front of centrifuge cavity 6, and drive shaft fixing piece 9 is fixed
6 inner cavity of centrifuge cavity between oil outlet 3 and liquid inlet 4, is set to form two chambers, drive shaft in centrifuge cavity 6
9 centre of fixing piece is provided with circular hole, and rotatory is located at 7 position of accent of 6 big-taper-angle taper segment of centrifuge cavity.Drive shaft 8 is
Hollow cylinder, one end are provided with radial hole 11, and drive shaft 8, which is located in centrifuge cavity 6, passes through drive shaft fixing piece 9, driving
8 one end of axis is connect with 1 output shaft of motor by shaft coupling, and 8 other end of drive shaft and rotatory are connected.Centrifuge cavity 6 and electricity
Machine junction installs sealing ring additional；Oil outlet 3 on centrifuge cavity 6 installs sealing ring additional at liquid inlet 4.
Rotatory 10 use three pieces grid, rotatory axial length be 150mm, grid diameter be 46mm, rotatory 10
In in rotating cylinder.Rotatory should minimize gap on rotatory and cylindrical hole inner wall.Synchronous rotary cylinder is added simultaneously, to weaken
Emulsification pretreatment effect, steady flow condition.
The course of work
Oil-water mixture enters from liquid inlet 4, rapidly rotates under the action of rotatory 10 intracavitary, generates strong whirlpool
Stream, the mixed liquor then come push it to continue to move ahead, and movement is in scroll.It is detached from the oil water mixture high speed of rotatory 10
It rotates and continues to move, hence into big-taper-angle taper segment 12.Big-taper-angle taper segment 12 connects hereafter centrifuge cavity with overflow segment 13
Internal diameter is gradually reduced, and rotation speed continues to increase, after biggish big-taper-angle taper segment 12, be transitioned into rapidly length it is larger, cone
The lesser overflow segment 13 in angle, herein, diameter change is slow, and rotary acceleration tends to mitigate.To realize water-oil separating.Water from
Front end water outlet 5 is gone out, and oil is gone out by hollow drive shaft radial hole 11 from the oil outlet 3 at top by hollow drive shaft 8.Liquid
When body generates eddy motion, the pressure distribution of radial direction is differed, and boundary is higher, and nucleus is lower, thus to continuous phase
Drop in liquid generates a centripetal difference force；Mixing liquid is in intracavitary rotary motion, because inertia force acts on, different liquid phases
Particle generates different size of active force, therefore there are the effects of a centrifugal force for oil droplet；Oil droplet moves in actual liquid, deposits
The Stokes resistance caused by viscosity.
If water density ρw, oil droplet density ρ0, droplet diameter x drop is in flow field mainly by three power:
(1) the inertia force F that rotation generates1=ma；
It is (2) radial that there are centripetal force caused by barometric gradient
(3) the stoke resistance F that low-speed motion generates in viscous liquid due to drop3=3 π μ ux.
Under the effect of these three power, the big phase-water of density is thrown toward surrounding, and moves downward along wall surface, as underflow
Discharge, into seawater；To axe movement, back overflow is discharged and intracavitary in front side the small phase-oil of density out of hollow drive shaft
Accumulation, eventually enters into fuel reserve tank, is achieved in the separation rapidly and efficiently to grease, and by oily matter recycling and reusing.
