Description

Vortex draws row's leafy road lampblack absorber (blower fan)

Technical field the present invention relates to a kind of vortex and draws row's leafy road lampblack absorber (blower fan), has especially installed a kind of volution blade and structure thereof that meets three-dimensional vortex mechanics principle, and blade effect downstream realizes from being in harmony, in order, flow without barrier at Ye Daoli.The present invention has reformed conventional fan blade and working method thereof; The property created having solved three-dimensional volution blade (containing industrial fan) rationally constructs a difficult problem.

It is one of family expenses blower fan of a kind of extensive use that the background technology kitchen draws smoke exhaust, is linking ten million user's physical and mental health and interests.Usually drawing cooking fume removing arrangement is to rotate through motor-driven blade (hour wheel, leaf fan), utilizes centrifugal force to draw row and separates the oil smoke effect.Draw at present that smoke exhaust (blower fan) blade adopts mostly or imitated " wheel formula (squirrel-cage) " impeller traditional over external more than 100 years, or " spiral " blade (impeller, leaf fan).Since blade be mostly the plane formula minor axis to stroke, lack action time, the row's of drawing power is little; Blade structure is not inconsistent three-dimensional vortex power effect principle, so gas-flow resistance is big, and noise is big; Be difficult to noise control that (or reluctantly) be up to state standards mostly in the following requirement of 75db, Oil-gas Separation is not thorough, and blade accumulation greasy dirt is difficult for cleaning; Influencing the service life of lampblack absorber (blower fan), more seriously is the high noisy standard, influences user's physical and mental health.People urgently hope lampblack absorber (blower fan), have high quiet, high effect, height and draw row " three height ", economize superior functions such as power, stable operation.The particularly noise control of lampblack absorber (blower fan); Suggestion improves below environmental protection national standard 40～60db, and standard has improved, and traditional blades such as wheel formula (hour wheel, leaf fan) structure is if no longer improve; Maybe will be eliminated, lampblack absorber (blower fan) manufacturing industry is faced with the severe opportunity that reshuffles.

Summary of the invention the present invention transforms the rotating vane of lampblack absorber (blower fan) and innovates; A kind of volution blade structure and structure thereof that meets three-dimensional vortex mechanics principle proposed; It is characterized in that many (at least one) strip blades are continuously in order periodically around axostylus axostyle (claiming axostylus axostyle Shi Yedao); Or fuselage inboard (title fuselage formula does not have axostylus axostyle leaf road) setting, the orderly variation of demands of different is all arranged on three dimensions in axial, hoop, cambered surface degree around middle blade.Make oil smoke gas (air-flow) in the leaf road flows, realize continuously, be in harmony certainly, in order, long duration of action power, three-dimensional vortex flow without barrier, reach the instructions for use that high quiet, high effect, height are drawn row's " three height ", environmental protection, province's power, stable operation.

For realizing the object of the invention, the technical scheme of employing is:

1, a kind of vortex draws the lampblack absorber (blower fan) in the leafy road of row, comprises fuselage, draws cigarette (air inlet) mouth, draws flue (air channel), three-dimensional volution blade; Vortex leaf road, spindle rod cover, front end air intake spiral case, variable-frequency motor; Exhausting duct, spindle rod, axostylus axostyle (or fuselage) bearing, and auxiliary equipment etc.Especially three-dimensional volution blade and Ye Dao; It is characterized in that: according to the requirement of three-dimensional vortex mechanics principle, by many (being no less than one) strip degree of broadening continuously (but discontinuous is continuous) around spindle rod cover (or fuselage) polycyclic around being connected to form leafy road; Blade all has different separately, orderly rule to change on axial, hoop, cambered surface degree three-dimensional: blade is changed by nearly 0 ° (vertical) to nearly 90 ° (levels) with the main shaft inclination angle in order; The radian of blade is changed to elliptical arc surface by arc surface in order; Ascending or the arrogant and little ground of the radially radius (comprising fuselage) of blade changes in order; The leaf track pitch of blade from childhood and the earth changes in order.

2, described three-dimensional vortex leaf road; By multiple-blade periodically around the three-dimensional vortex Ye Dao space that forms multiple-blade, leafy road, long stroke shaft; Fan blade was configured with around axostylus axostyle cover around (claiming axostylus axostyle Shi Yedao), or (no axostylus axostyle) around the fuselage inboard around (claiming no axostylus axostyle Shi Yedao); The blower fan fuselage is tightly connected through flexible joint and flexible pipe, front and back spiral case; But blower fan fuselage any direction and location means; Change, terminal blade angle and camber, make air-flow form side direction type, multiple gas or the exhaust mode of drawing such as axial type.

3, described three-dimensional vortex leaf road is preferably 3～5 for the quantity of lampblack absorber blade, and the cycle of rotation forms 2～4 blade plane roads between (π/4～2 π); For high-power industrial fan, the quantity of blade is preferably 3～m sheet, and (m: the number of blade), the cycle of blade rotation is about (between π/4～N), forming 2～N leaf road (N: leaf road number), be different from a traditional blade plane road working method; Can adjust blower fan neatly and draw instructions for uses such as discharge capacity, power, wind speed, blast, the axial stroke length in design blade plane number, leaf road number, blade radius, leaf road.

4, described lampblack absorber (blower fan) accessory device has: oil cleaner screen, oil trap, (automatic or manual) cleansing solution sprayer; The cleaning solution jet, regularly protection, and over-temperature protection device; Be convenient in airflow, control and spray into the cleaning solution foam; Automatically clean (exempting to unpick and wash), reclaim waste liquid automatically, and prevent unexpected out-of-date, the excess temperature accident of misoperation.

The present invention has reformed conventional fan blade and working method; The property created having solved three-dimensional volution blade rationally constructs a difficult problem; Make and realize in the Ye Dao space of gas earthquake, the superiority of have high effect, height is quiet, height draws row's power, resistance is little, power is economized, be widely used etc. from being in harmony, in order, flow without barrier.
