Abstract
A duct increasing in cross-sectional area is provided with a screen means on its upper wall. An adjustable baffle is hingedly fixed to the lower wall of the duct at the inlet. Air-borne material carried in an air stream introduced at the inlet is separated from the stream by projection against the screen. The adjustable baffle directs the air-borne material onto the screen.
Claims3
Apparatus for continuously separating air-borne material, comprising:
- an inlet for air-borne material;
- an outlet for separated product;
- a duct connecting said inlet to said outlet and increasing in a cross-sectional area away from said inlet, the axis of the duct being angular with respect to the inlet;
- screen means arranged to form at least one upper wall of said duct for removing air from within said duct;
- a lower wall of said duct opposite said screen joining the inlet and defining a first angle with said screen to form said increasing cross-sectional area for decelerating incoming air-borne material to separate material from incoming air;
- the inlet having an inlet axis intersecting said screen at a second angle;
- an adjustable baffle hingedly fixed to the said lower wall and forming a portion of said inlet for directing air-borne material onto said screen at an angle effective to form an air flow boundary layer adjacent said screen which precludes said air-borne material from contacting said screen while permitting air removal through said screen.
