Spray axial fan be in wheel hub design and installation mechanical atomization device, after the humidification water entered mechanical atomization device, under blower fan rotary centrifugal force and blower fan back side suction function, water flowed out along the annular pass of mechanical atomization device, forms the cutting of water curtain.Water curtain after the cutting be transferred air mixing after, rush at the impeller blade of high speed rotating, and hit by blade and to be ground into superfine droplet, thereby realized the double action of blower fan air-supply and humidification.The core component of spray axial fan is an impeller.In the past, the impeller blade profile often adopts the narrow leaf type, and (for example air quantity is greater than 18 * 10 but the blower fan total head of this blade profile and flow can not satisfy the use occasion of big air quantity
4m
3/ h, blast is greater than 600Pa).In recent years, big air quantity spray axial fan has also appearred on the market, but these blower fans exist major defect such as poor performance, efficient are low, noise height, its energy consumption is big, noise pollution is serious.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existing blower fan, a kind of spray axial fan impeller that can make big air quantity spray axial fan possess high efficiency, low noise, big air quantity performance to be provided.
The big air quantity spray axial fan of a kind of high-efficient low-noise of the present utility model impeller, mainly constitute by wheel hub and 8～9 blades that are evenly distributed on the wheel hub, the blade profile of described blade is a wing blade, the established angle of blade tip primitive blade profile is 14 °～24 °, and the chord length of blade tip primitive blade profile is 0.3～0.4 with the ratio of length of blade; Blade is big distortion character, and the established angle of root of blade primitive blade profile is 42 °～52 °, and the chord length of root of blade primitive blade profile is 0.4～0.5 with the ratio of length of blade; The chord length of blade mean radius place primitive blade profile is 0.40～0.45 with the ratio of length of blade; Root of blade is to the vane thickness of blade tip attenuate gradually, and at root of blade, vane thickness is 0.12～0.15 with the ratio of blade chord length; And at blade tip, vane thickness then is 0.08～0.12 with the ratio of blade chord length.
Impeller blade profile of the present utility model can guarantee that spray axial fan is in (10～16) * 10
4m
3/ h, high efficiency, low noise running in total head 300～800Pa working zone make spray axial fan have that flow is big, blast is high, efficient is high, low noise advantages, and to cutting water smoke, refinement droplet, improve nebulization efficiency good result arranged.
