1~Fig. 2 of reference picture, smoke separating purification blower fan apparatus, include air duct 1, blower fan 2, institute are provided with the air duct 1
State separation impeller 21 before blower fan 2 includes, rear separation impeller 22 is fixed on wind with motor 23, the motor 23 by support frame 24
Among cylinder 1, described support frame can be welded on the inwall of air duct, and motor is fixedly connected by bolt with support frame；It is described
Separation impeller 21 is rotated before motor 23 drives, and separate impeller 22 after described is connected by mounting seat 25 with air duct 1, likewise, institute
The mounting seat stated is fixed by welding in the inwall of air duct, and the mounting seat 25 is provided with rotating shaft and two bearings, after described
Separation impeller 22 is connected with rotating shaft, and rotating shaft freely rotates within the bearing, so that separation impeller can be rotated by the wind afterwards；It is described
Impeller 22 is separated afterwards with before separating axis coinciding of the axle center of impeller 21 with air duct 1；Separation impeller 22 is with before separating after described
The specular each other of impeller 21.Described preceding separation impeller is rotated by motor driven, and the rear impeller that separates is by preceding separation impeller rotation
Caused air-flow drives rotation, and oil smoke is first by preceding separation impeller, and due to viscosity, oil and gas and steam can condense and be attached to leaf
On piece, then it can get rid of to air duct, then be discharged by the effect of centrifugal force, oil and water, after preceding separation impeller, also not
Clean oil and gas and steam are separated again by rear separation impeller, is further carried out separating with same principle, due to separating leaf
The rotating speed of wheel two can also reduce less than separation impeller one, relative wind velocity so that the time of contact of air-flow and blade is longer so that oil
Being left away with moisture, it is more efficient to remove.And in order that the rotation that impeller is separated after obtaining is more stable, described rear separation impeller is with before
Impeller specular is separated, separation impeller rotates more glibly after the wind driving of preceding separation impeller discharge, effectively reduces windage.
Preferred embodiment is further used as, the front end of the air duct 1 is provided with current collector 3, the current collector 3 and wind
The air inlet connection of cylinder 1, the current collector 3 are the junction arc transition of trumpet type, the current collector 3 and air inlet.Pass through
Current collector can increase air draught area so that purification efficiency is higher.
Preferred embodiment is further used as, the blower fan 2 also includes motor protecting cover 26, mounting seat protective cover
27, institute's motor protecting cover 26 is enclosed on outside described motor 23, and described mounting seat protective cover 27 is enclosed on outside described mounting seat 25.
With being equipped with discharge duct 28 on mounting seat protective cover 27, the outer end of the discharge duct 28 reaches the motor protecting cover 26
Outside air duct 1.By protective cover, it can cause motor and bearing exempts from the erosion of oil gas, the service life of extension device, and
So that separation wheel rotation is more smooth.Meanwhile by discharge duct can motor and bearing energy ventilation, reduce work
Make temperature.
Preferred embodiment is further used as, the air duct 1 is provided with two grooves 11, the position of two grooves 11
Put respectively with preceding separate impeller 21, after separate that the position of impeller 22 is relative, described air duct is provided with a circle groove in impeller section
11, the width of groove is more slightly wider than impeller width, and groove devises gradient, and the bottom of groove is provided with sewage draining exit.
Preferred embodiment is further used as, the air duct 1 includes preceding air duct 12 and rear air duct 13, the preceding air duct
12 are connected with rear air duct 13 by flange, and separating impeller 21 before described is arranged in preceding air duct 12, and separating impeller 22 after described pacifies
In rear air duct 13.Using front and rear Wind cylinder structure, the installation, dismounting and maintenance of blower fan can be facilitated.
Preferred embodiment is further used as, separating impeller 21 before described includes wheel hub 211, the wheel hub 211
Periphery is fixed with the blade 212 of multi-disc, and for the blade in the strip of distortion, the root of the blade 212 is fixed on wheel hub 211
On, the outside of the blade 212 is provided with stiffening ring 213, and the width of the stiffening ring 213 is less than the height of the axial direction of blade 212.
Blade by using multi-disc distortion strip causes oil smoke to have sufficient contact area with blade so that oil smoke can be on blade
Gather and then taken out of by centrifugal force；And have grease because the outside of blade in work can be gathered, it is certain make it that blade produces
Distortion, therefore the intensity of blade can be improved by the stiffening ring of blade exterior, ensure the rigidity of high speed lower blade, moreover, plus
The width enclosed by force can not be more than the axial height of blade, otherwise influence whether the normal work of blade.
It is further used as preferred embodiment, the blade 212 is the distorted shape of gradual change, the distortion of the blade 212
Angle is gradually successively decreased from root to outside.
Preferred embodiment is further used as, the distortion angle of the root is 30-40 °, the twist angle of the outside
Spend for 20-30 °.By optimizing the shape and structure of blade, more preferable oil smoke separating effect can be obtained.
When bringing into operation equipment, motor is opened, separation impeller before the mixed gas of oil smoke and air is inhaled into, due to viscous
Property, before oil and gas and steam can be condensed and is attached on the blade of separation impeller, then pass through the effect of centrifugal force, oil and water meeting
The groove to air duct is got rid of, is then discharged by sewage draining exit.After preceding separation impeller, clean oil and gas and steam are not separated also
Again by rear separation impeller, it is further carried out separating with same principle, You Heshui gets rid of the groove to air duct, then passes through row
Dirty mouth discharge.Because rear separation impeller is by air stream drives caused by preceding separation impeller rotation, turning for impeller is separated later
Speed can also be reduced less than preceding separation impeller by the wind speed of impeller so that and the time of contact of air-flow and blade is longer, so that
Oil and moisture leave away remove it is more abundant.By the separation of former and later two impellers, the oil and gas and water of bulky grain can be substantially removed
Vapour, the electrostatic precipitator that remaining small particle enters back into peripheral hardware are purified, and so both protect electrostatic precipitator to save
Electric energy reduces the workload of cleaning airduct again.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
