Abstract
The utility model discloses an automatic rotating centrifugal oil throwing impeller for oil-gas separation of a range hood. The automatic rotating centrifugal oil throwing impeller consists of a slope-shaped oil gathering ring, a crossed supporting frame and a centrifugal impeller, wherein four outer ends of the crossed supporting frame are fixedly connected with the slope-shaped oil gathering ring; the center of the crossed supporting frame is connected with an axis of the centrifugal impeller through a bearing; the centrifugal impeller is arranged in the slope-shaped oil gathering ring and can flexibly and freely rotate under the supporting of a center shaft of the crossed supporting frame; the axial flow centrifugal impeller consists of 8-10 centrifugal blades which are integrally processed in the form of an involute and are provided with torsional angles. When a fan is started, and lampblack gas flow which flows into a suction opening flows through the centrifugal impeller, the centrifugal impeller can automatically rotate and generate centrifugal force and certain suction force; when oil particles mixed in flue gas collides the centrifugal impeller, the oil particles attached to the centrifugal impeller are thrown to the surrounding oil gathering ring under the action of the centrifugal force and then flow into an oil storage box of the range hood; the centrifugal blades are in the involute form which approaches a trace formed by a fact that the oil particles are thrown away by the centrifugal force, and the oil particles cannot fall off; the residual lampblack is sucked into the fan and is discharged out of a room through clearances between the centrifugal blades. The automatic rotating centrifugal oil throwing impeller is suitable for families and catering industries with large lampblack content and retrofitting and modification of new and old range hoods.
Description
Affiliated technical field
The utility model relates to oil on a kind of family kitchen and little food and drink range hood suction inlet and the separator of flue gas, especially by getting rid of the centrifugal action of oily impeller, the mist of oil sticking on impeller is got rid of on peritropous poly-oil ring, along poly-oil ring, flow to lampblack absorber in the oil collection box of below again, most the old and new's lampblack absorbers all can be installed this device, and make range hood reach the discharge standard of national regulation, also allow user remove from and tear the oily worries of machine washing open simultaneously.
Background technology
At present, the Oil-gas Separation form of range hood is a lot, best results surely belong to 01250306.1 and the former weak point of ZL201020230118.0. be user while cleaning net dish dismounting loaded down with trivial details, the more important thing is that mist of oil gets rid of in peritropous process and has landing phenomenon midway on finer wire, this just greatly reduces and gets rid of oily efficiency.Although utilizing, the latter have certain thickness mazy three-dimensional micropore to carry out Oil-gas Separation, its separating effect can reach 100%, but what user was reluctant to wash for two days one frequently reuses, and disposable use dislikes again use cost too high, is difficult to again deal with a large amount of oil smoke as continuous in catering trade.
Summary of the invention
For the Oil-gas Separation that makes range hood more thoroughly and to allow user use convenient, for the weak point of existing lampblack absorber, the utility model provides a kind of most the old and new's lampblack absorber automatic rotation centrifugal oil swirling impeller can be general and that can reach best oil gas separation.
The utility model solves the technical scheme that its technical problem adopts: a poly-oil ring of annular adapting with lampblack absorber suction inlet size, its back side is fixed with cross supporting frame, cross center is fixed on the ring flange with semiaxis, semiaxis on ring flange and the centre bearing of centrifugal impeller match, there is certain interval the outer of centrifugal impeller from poly-oil ring, the rotation of centrifugal impeller energy freedom and flexibility.Centrifugal impeller is to process by the metal sheet disk integral body that a slice diameter is slightly less than poly-oil ring external diameter, and metal sheet disk outer is slit into the even decile of involute shape the centrifuge blade that 8 to 10, outward flange are connected as a body with interior approximately 5 millimeters.Each blade is had increasing torsion angle to produce certain suction to the center of circle by cylindrical, also form certain interval simultaneously and be convenient to air-flow and pass through.
After starting blower fan, when the cooking fume flow path that suction inlet sucks is crossed the centrifuge blade of involute shape, air-flow can promote centrifuge blade rotation.Its rotating speed increases along with the increase of rotation speed of fan; When the elaioleucite in oil smoke bumps against the centrifuge blade of involute shape, by High Rotation Speed the centrifuge blade that produces centrifugal force, got rid of the poly-oil ring to surrounding, because centrifuge blade shape is involute shape, when approaching oil droplet and throwing away the track of process, therefore in getting rid of oily process, oil droplet does not have the phenomenon that leaves the right or normal track that comes off, this has just guaranteed to get rid of to greatest extent oily rate greatly, and remaining flue gas is sucked into outside blower fan discharge chamber along involute shape gap.
The beneficial effects of the utility model are, by the orderly centrifugal oil swirling effect of involute shape centrifuge blade, can the oil in more a large amount of oil smoke be got rid of to the poly-oil ring of surrounding efficiently flows in oil storage box again, oil and flue gas in oil smoke are separated to greatest extent, and the utility model is applicable to family and the large more anxious catering trade of oil smoke.

The specific embodiment
According to the poly-oil ring (1) in diagram, make with domatic annulus approximately 30 ° of domatic and circular planes angles.The center of cross supporting frame (2) is fixed with semiaxis (3), and (2) four outer ends of cross supporting frame and poly-oil ring (1) are fixing.Centrifugal impeller (4) is to be processed by thin metal disk integral body, can not run into boss resistance like this in getting rid of oily process, can the smooth and easy oil that gets rid of rapidly.Apart from thin metal disk outer, approximately 5 millimeters are divided into the centrifuge blade (6) of 8 to 10 slice consistent with blower fan direction of rotation with involute (5) molded line by thin metal disk inward, each blade of centrifugal impeller (5) flows to Inbound in direction of rotation forward position vigor and by cylindrical, to the center of circle, is made increasing torsion angle (7), by approximately 40 ° of paracentral maximum twist angles, so just make each centrifuge blade (6) forward position exceed edge after last centrifuge blade, form the gap (8) being staggered between each blade; The center of centrifugal impeller (5) studs with bearing (9) and matches with semiaxis (3); Deflection cone (10) can reduce gas-flow resistance, allows air-flow flow in an orderly manner and gets rid of oily centrifuge blade.After starting blower fan, first the flue gas that is mixed with elaioleucite hits centrifuge blade (6) while flowing into lampblack absorber suction inlet, centrifuge blade (6) is with torsion angle, under the effect of blower fan suction, understand automatic rotation and produce centrifugal force and suction, the elaioleucite sticking on centrifuge blade (6) gets rid of on the poly-oil ring (1) of surrounding along involute shape track under centrifugal action, along the oil storage box that gathers the domatic inflow range hood bottom of oil ring (1), remaining steam is by outside clearance diameter blower fan discharge chamber between staggering between adjacent two blades again.The oil smoke that the utility model is can be fast separated more greatly, more anxious, and be applicable to the add-assembly of new and old lampblack absorber, removes user to unpick and wash the worry of lampblack absorber more to extend the service life of range hood and purified living environment.
