Description
Technical field
The utility model relates to a kind of wind wheel, specifically is a kind of centrifugal unidirectional wind wheel.
Background technique
At present, most of wind wheels are to utilize unidirectional blade to realize the centrifugal unidirectional wind wheel of unidirectional air draft on the market, but this unidirectional wind wheel is not because the design of blade angle and blade shape reaches the perfect performance requirement, thereby cause ventilation efficiency lower.China Patent No. 200420093992.9 disclosed a kind of hypsokinesis centrifugal wind wheels comprise ring washer, blade and mid-game, it is characterized in that: described blade and mid-game plane form the angle less than 90 °.It is said, this model utility has formed the impeller interior flow field that is similar to the ternary runner by blade with respect to being in tilted layout of mid-game, by changing the variation of cross section of fluid channel shape, can significantly reduce the eddy current loss that produces because of the blade airflow breakaway in the impeller, improve impeller adiabatic efficiency.But in fact this wind wheel improvement threshold is less, raising impeller adiabatic efficiency that can not be bigger.
The model utility content
The purpose of this utility model aims to provide a kind of simple and reasonable, centrifugal unidirectional wind wheel that can bigger raising ventilation efficiency, to overcome deficiency of the prior art.
A kind of centrifugal unidirectional wind wheel by this purpose design comprises ring washer, wheel hub and unidirectional blade, unidirectional blade is arranged between ring washer and the wheel hub, its structure characteristic is that unidirectional blade is divided into two kinds: a kind ofly be short blade radially, another kind ofly be linear leaf radially, the alternate setting of deviated splitter vane.
Described radially short blade one end is arranged on the ring washer inboard, and the other end is arranged on the wheel hub outside, short blade and rotor shaft line parallel; Linear leaf one end is arranged on the ring washer inboard, and the other end is arranged on the wheel hub inboard, and linear leaf favours the wind wheel axis.The cross section of short blade is J font or circular arc, and the cross section of linear leaf is circular arc or J font.
Described J font short blade is made up of straightway and arc section, and the angle of the line at its straightway and straightway starting point and wind wheel center is 40 °～50 °; The angle of the initial tangent line of the circular arc of described circular arc linear leaf and the initial point of contact of circular arc and the wind wheel line of centres is 50 °～60 °.The longitudinal section of described linear leaf is slurry shape or galosh shape, connects wheel hub at the bottom of the boots, and the boots top connects the ring washer inboard.
The utility model is simple and reasonable, because the hybrid type blade that adopts J font blade and circular arc vane to combine can make this product under identical external condition, increase blast and air quantity that can be bigger than other products, improve ventilation efficiency, thereby improve overall efficiency.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 4, this centrifugal unidirectional wind wheel comprises ring washer 1 and wheel hub 4, and unidirectional blade is arranged between ring washer 1 and the wheel hub 4, and unidirectional blade is two kinds: a kind ofly be short blade 2 radially, another kind is linear leaf 3 radially, the alternate setting of deviated splitter vane.The cross section of short blade 2 is the J font, and short blade 2 is arranged on ring washer 1 inboard and wheel hub 4 outsides, short blade 2 and rotor shaft line parallel; The longitudinal section of linear leaf is slurry shape or galosh shape, connects wheel hub 4 at the bottom of the boots, and the boots top connects ring washer 1 inboard, and linear leaf 3 favours the wind wheel axis.In the present embodiment, deviated splitter vane 3,2 quantity equate, and deviated splitter vane 3,2 is spaced separately.
Referring to Fig. 3, J font short blade 2 is made up of straightway and arc section, and wherein the α angle is the angle of inclination of straight line, i.e. the angle of the line at straightway and straightway starting point and wind wheel center, general α=45 ° ± 5 °; L is a length of straigh line, and length of straigh line is 6.5mm～8.5mm; R2, R1 are inside and outside circular arcs, and arc section circular arc size is 4mm～8mm, and the central angle of circular arc is 65 °～80 °; The angle of inclination of J font short blade 2 straightways and the crooked radian of arc section can change within the specific limits.The b angle is the start angle of circular arc on the circular arc linear leaf 3, i.e. the angle of the initial tangent line of circular arc and the initial point of contact of circular arc and the wind wheel line of centres, general b=55 ° ± 5 °.R3 is the radian size of blade.The blade profile size is presented along the wind wheel axis and is increased variation, and blade edge is spline curve to be changed, and the central angle of place, maximum cross-section circular arc is 85 °～105 °, the central angle of smallest cross-sectional place circular arc is 35 °～55 °, wherein, the maximum cross section is at wheel hub 4 ends, and minimum cross-section is at ring washer 1 end.The radian of arc section and maximum arc length and minimum arc length can change within the specific limits on the circular arc linear leaf 3.The pairing diameter of the maximum area that the present embodiment blade surrounds is Φ 60mm～Φ 100mm, and length of blade is 30mm～50mm.
