Abstract
Apparatus for loading an enclosure with particulate solids includes a loading hopper, a discharge chute (integral with the hopper), and a movable member disposed below the outlet opening of the chute. The movable member includes a shaft driven in rotation by a motor and flexible, moderately hard deflecting strips, which are articulated to the shaft or to a structure rigidly integral with the shaft, so as to spread out from the shaft at an angle by the effect of centrifugal force when driven in rotation. At least one discharge opening is provided in the side wall of the hopper and/or of the chute in the direction of the rotating deflecting strips.
Claims20
An apparatus for loading an enclosure with particulate solids in the form of a dense bed, which comprises a loading hopper for the particulate solids, a discharge chute for the hopper having a discharge end, a motor means, a shaft driven by said motor means and extending substantially parallel to the axis of the discharge chute and out the discharge end thereof, flexible moderately hard deflecting means which are articulated at a first end to the shaft beyond the discharge end of said chute in a manner adapted to provide a second free end of the deflecting means opposite the first end such that the deflecting means diverge angularly from a downward position towards an outward position by the effect of centrifugal force when the shaft is rotated, and at least one side discharge opening in the side of the hopper or in the side of the chute such that particulate solids passing therethrough are directed towards the free ends of the centrifugally extended deflecting means.
A method of charging an enclosure with particulate solids in the form of a dense bed, which comprises positioning an apparatus having a loading hopper for the particulate solids, a discharge chute for the hopper having a discharge end, a motor means, a shaft driven by said motor means and extending substantially parallel to the axis of the discharge chute and out the discharge end thereof, flexible moderately hard deflecting means which are articulated at a first end to the shaft beyond the discharge end of said chute in a manner adapted to provide a second free end of the deflecting means opposite the first end such that the deflecting means diverge angularly from a downward position towards an outward position by the effect of centrifugal force when the shaft is rotated, and at least one side discharge opening in the side of the hopper or in the side of the chute such that particulate solids passing therethrough are directed towards the free ends of the centrifugally extending deflecting means with said deflecting means extending down into said enclosure through an access hole, rotating said shaft by said motor means, and feeding said particulate solids through said hopper to said deflecting means to charge said enclosure.
Method of charging with particulate solids in the form of a dense bed an enclosure having a non-circular cross section or an off-center access hole, which comprises positioning an apparatus having a loading hopper for the particulate solids, a discharge chute for the hopper having a discharge end, a motor means, a shaft driven by said motor means and extending substantially parallel to the axis of the discharge chute and out the discharge end thereof, flexible moderately hard deflecting means which are articulated at a first end to the shaft beyond the discharge end of said chute in a manner adapted to provide a second free end of the deflecting means opposite the first end such that the deflecting means diverge angularly from a downward position towards an outward position by the effect of centrifugal force when the shaft is rotated, and at least one side discharge opening in the side of the hopper or in the side of the chute wherein one or more side discharge openings are oriented and distributed nonuniformly about the axis of the shaft such that particulate solids passing therethrough are directed towards the free ends of the centrifugally extended deflecting means with said deflecting means extending down into said enclosure through said access hole, rotating said shaft by said motor means, and feeding said particulate solids through said hopper to said deflecting means to charge said enclosure.
