Specific implementation mode
Invention is further described in detail below in conjunction with the accompanying drawings.
A kind of centrifugation blade of the present invention includes shroud 1, hub disk 3 and multiple blades 2 (as shown in Figure 1 and Figure 4).Wherein, preceding
Air inlet is provided on disk；It is provided with air outlet between hub disk 3 and shroud 1；Multiple blades 2 are evenly spaced in shroud 1 and hub disk 3
Between；Wherein, the rear of blade 2 is arranged to zigzag fashion, forms trailing edge sawtooth 2.1；Air-flow enters centrifugation from air inlet
In fan blade, the leading edge through blade is into air stream enter runner, then rear through blade is flowed out from air outlet.The present invention can improve centrifugation wind
The centrifugal blower of leaf including above-mentioned centrifugation blade and the working efficiency for including the centrifugal blower air cleaning facility, reduce from
The noise and power consumption of heart fan blade, centrifugal blower and air cleaning facility.
For installing fan blade 2, wind wheel is made of the hub disk 3 of the centrifugation blade 7-11 blade, and blade 2 is used with hub disk 3
Ultrasonic welding process ensures that weld strength and reliability are high, and does not influence appearance.The stagger angle a angles of blade 2 are
20-40 °, exit installation angle b angles are 30-50 °, and stagger angle a is the air intake surface tangent line side opposite with fan blade direction of rotation
To the angle with blade air intake surface circular arc tangential line, outlet air angle b is the outlet air surface tangential direction opposite with fan blade direction of rotation and leaf
