Smoke machine main body is provided with shell 2 and oil collector sump tank 3, and oil fume separator 1 rotates the inside for being installed on shell 2, exhausting
5 fixing assembling of component is assemblied in the bottom of shell 2 in the inside of shell 2, oily device.
Shell 2 be provided with multiple housing inlets 21 and with 21 matched annular lamina 22 of multiple housing inlets, annular lamina
22 integrally connected shell, 2 corresponding inner surface and with positioned at the edge of housing inlet 21, annular lamina 22 and housing inlet 21
It corresponds, annular lamina 22 of the invention can also be fixedly installed in shell, depending on specific embodiment is with performance.
The effect of annular lamina 22 is vortex to be generated when soot gas being made to enter shell 2, while preventing soot particles from throwing away again
When oil fume separator 1 exterior space is thrown away from the housing inlet 21 of shell 2.The shell 2 of the present invention is spherical housing 2
The operation principle of kitchen ventilator is：Kitchen ventilator is opened, motor drives oil fume separator 1, the wind wheel 51 of exhausting component 5 same
When rotate, soot particles pass through seven layer separations inside kitchen ventilator, and most almost clean gas is discharged through gas outlet again finally.This
Seven layer separations are specific as follows：
First layer separation, inertial separation：Oil smoke enters via the housing inlet 21 of shell 2 inside smoke machine, and oil smoke enters
Enter annular lamina 22 after housing inlet 21, because of 21 area of pressure difference and housing inlet of shell 2 inside and external environment
Cataclysm, air velocity can accelerate, and moment of inertia also relative increases.And oil smoke can form very thin around annular lamina 22
Boundary layer, and because the housing inlet 21 and annular lamina 22 of shell 2 are in angle, oil smoke is forced to flow downward along annular lamina 22
Just up flow into oil fume separator 1 afterwards, thus heavier oil opened with crude oil plume field point in downward inertia motion it is past
The oil collector sump tank 3 in 2 bottom of shell is collected in lower movement, realizes first time inertial separation.
Second layer separation, cyclonic separation：Soot particles by the first layer separation are in the direction of annular lamina 22 by lower turn
Flowing in further occur flow field separation, soot particles flow field detach under cause unsteady flow field, be further formed vortex.
Flow field or vortex can interact influence with neighbouring flow field or vortex, and the flow field for not stopping spinning is formed in annular lamina 22, this
When rotating vortex reach maximum vorticity.The lighter oil smoke of remaining part can not be parked in the rotating vortex accumulation of annular lamina 22, when
When running up to constant weight, flow field branch is unable to hold out the weight of oil droplet, will fall downwards or flow to oil collector sump tank along annular lamina 22
3。
Third layer separation, centrifugal force separate：Eaves portion structure 13 follows the rotation of concentric tube 11 to form centrifugal force, centrifugal force and pumping
The attraction of wind component 5 interacts.After second detaches, the lighter oil smoke of remaining part is first when entering concentric tube 11
The outermost end for touching eaves portion structure 13 enters back into concentric tube 11, the centrifugal force of 13 outermost end of eaves portion structure can segment fluid flow or
Person's soot particles take away or stop into 11 inside of concentric tube and move outward, then are thrown away with higher tangential velocity, are thrown out of
Particle can be fallen in annular lamina 22, and oil collector sump tank 3 is flow to finally along annular lamina 22.
4th layer separation, inertial separation and centrifugal force separate：After third layer separation, the oil smoke of remaining lighter weight is same
When by centrifugal force and attract force effect, but opposite attraction be more than centrifugal force.A portion of these oil smoke can be through
It crosses through-hole 131 to flow to adjacent eaves portion structure 13, because effect of inertia and other oil smoke or soot particles pool larger oil
Smoke particle flow down, but because centrifuging force effect, soot particles are simultaneously flowed with being thrown away compared with high tangential velocity finally along annular lamina 22
Move oil collector sump tank 3.
Layer 5 detaches, and the cyclone centrifugal force of concentric tube 11 and secondary vortex generate：11 inner wall of concentric tube rotates to form gas
Rotation, concentric tube 11 be low-pressure area under the action of the centrifugal force, fluids within pipes or particle etc. are moved toward duct wall, and tube wall forms height
Tangential velocity, part oil smoke, which is blocked, to be flowed up.It is vortexed, does not stop in addition, remaining oil smoke can be formed in vortex generator
Spinning captures oil smoke and does not allow oil smoke to flee from pipeline.After attraction and centrifugal force remove, do not stop spinning secondary vortex flow and
The oil smoke that high tangential motion is carried out in tube wall can be collected because gravity flows downward to oil collector sump tank 3 along inner tubal wall.
Layer 6 detaches, and disturbing flow device 111 detaches：The disturbing flow device 111 of 11 one end of concentric tube generates remaining oil smoke
Flow field separation occurs, is detached by flow field, part oil smoke is stopped not because of the unstability in flow field toward flowing in length and spin
The vortex turned captures oil smoke.
Layer 7 detaches, 51 centrifugal force separate of wind wheel：After the first six layer separation, it is left a small amount of very light soot particles
The wind wheel 51 of exhausting component 5 is sucked because of pressure difference, the wind wheel 51 of rotation forms centrifugal force and remaining a small amount of soot particles are got rid of
Onto the inner wall of wind turbine 52, last almost clean gas is discharged external through gas outlet.
The oil fume separator 1 also has generates additional centrifugal force to soot gas, can effectively remove soot particles, be avoided that
It contacts, greatly improve the separating effect of soot particles and reduces because wind wheel 51 accumulates oil with wind wheel 51 containing a large amount of soot particles gases
Stain and the noise generated.Passive denoising device 6 can substantially reduce the noise generated when wind wheel 51 and the work of wind turbine 52 and vibration,
Greatly improve the satisfaction of user.
Embodiment 2.
A kind of kitchen ventilator that centrifugal force is combined with attraction, as shown in fig. 7, other features are same as Example 1, difference
Be in：The present embodiment acoustic damping materials are filled in outside wind wheel 51 and in spiral case 53, while also wrapping up noise reduction outside spiral case 53
Material.
Compared with Example 1, the present embodiment is stronger to the cushioning ability of exhausting component 5.The kitchen ventilator is at work more
The small noise that can slow down generates and vibration, greatly improves the satisfaction of user.
Embodiment 3.
A kind of kitchen ventilator that centrifugal force is combined with attraction, other features are same as Example 1, the difference is that：This
The concentric tube 11 of the n=4 of embodiment, i.e. the present embodiment are provided with 4.The present embodiment m=2, i.e. vortex generating means group 14 are set
2 are set to, one is set to the 4th concentric tube, another is set to the 3rd concentric tube.The concentric tube 11 and eaves of the present embodiment simultaneously
Portion's structure 13 corresponds.
The centrifugal force and the kitchen ventilator of attraction combination oil removing compared with Example 1, as soon as increase a concentric tube 11,
It is the increase in spatial volume of the oil fume separator 1 inside shell 2, to reduce the area of 11 air inlet of concentric tube, is improved
Gas admission velocity increases the pressure difference of 11 inside and exterior space of concentric tube, so as to improve the rate of departure of soot particles.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than is protected to the present invention
The limitation of range, although being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art should manage
Solution, can be modified or replaced equivalently technical solution of the present invention, without departing from the essence and model of technical solution of the present invention
It encloses.
