Detailed description of the invention
For making feature of the present utility model and advantage clearer, it is described below in conjunction with specific embodiment.
As shown in Fig. 1 ~ Fig. 2, a kind of impact dispersal device of air sorting machine for powder, including wind blade 1, powder-separating area 2, cage-type rotor 3, shock plate 4, support 5, wind blade 1 is centered around cage-type rotor 3 surrounding and forms annular cavity powder-separating area 2, it is provided with shock plate 4 in selecting the annular cavity type body of subregion 2, adjacent shock plate 4 head and the tail are overlapping, and adjacent shock plate 4 overlapping is provided with gap, is provided with gap between shock plate 4 and cage-type rotor 3.
In the present embodiment, described shock plate 4 is fixed on described support 5 end, and described support 5 root is fixed on the bottom of described powder-separating area 2；Described support 5 is fixed on described wind blade 1, and described support 5 is provided with described shock plate 4, and support 5 can take different fixed forms to connect shock plate 4, makes shock plate 4 have certain impact intensity, and when making powder impact, shock plate 4 maintains optimum tilt angle.
In the present embodiment, described shock plate 4 is provided with, to described cage-type rotor 3 center position, the inclined angle alpha favoured bottom described powder-separating area 2, described inclined angle alpha is 0 ° ~ 30 ° with the angle of horizontal plane, reunion powder is made when contacting with shock plate 4, to have one to select powder component in cage-type rotor 3, the powder after dispersion is conducive to enter in cage-type rotor 3, simultaneously in order to prevent powder on shock plate 4 from will not slip into discharge bottom powder-separating area 2, inclined angle alpha should not arrange excessive angle of inclination.
