First Claim
Patent Images
1. A particulate loader and transfer apparatus, comprising:
- an air-materials separating chamber;
a vacuum pickup hose coupled with the air-materials separating chamber for directing particulate materials into the air-materials separating chamber;
separating means within the separating chamber for separating the particulate materials from an air stream;
a discharge conveyor for transferring the particulate materials to a remote location; and
,a single stage blower capable of providing sufficient suction in the event the particulate material is difficult to move or the vacuum pickup hose is blocked, the single stage blower comprising;
a. at least one blade having a proximal and a distal end;
b. means for rotating the at least one blade in a direction about an axis of rotation;
wherein the proximal end of the blade is nearer to the axis of rotation than the distal end of the blade is to the axis of rotation and wherein the blade is angled so that as the blade rotates about the axis, the proximal end of the blade precedes the distal end of the blade and wherein a substantial portion of the blade is curved; and
,c. an inlet disposed concentrically to the axis of rotation and connected to the air-material separating chamber of the particulate loader and transfer apparatus for providing suction thereto.

Abstract
A blower for a particulate loader and transfer apparatus is provided. The blower comprises at least one blade having a proximal and a distal end. A drive mechanism rotates the at least one blade in a direction about an axis of rotation. The proximal end of the blade is nearer to the axis of rotation than the distal end of the blade is to the axis of rotation and the blade is angled so that as the blade rotates about the axis, the proximal end of the blade precedes the distal end of the blade.

9. A method for transferring particulate materials comprising:
-
providing an air-materials separating chamber; providing a vacuum pickup hose coupled with the air-materials separating chamber for directing the particulate materials into the air-materials separating chamber; providing separating means within the separating chamber for separating the particulate materials from an air stream; providing a discharge conveyor for transferring the particulate materials to a remote location; providing a single stage blower having an inlet disposed concentrically to an axis of rotation and connected to the air-materials separating chamber for providing suction thereto, the blower having a plurality of blades rotatable about the axis of rotation; rotating the plurality of blades in a direction about the axis of rotation, wherein a proximal end of each blade is nearer to the axis of rotation than a distal end of the blade is to the axis of rotation and wherein each blade is angled so that as the blade rotates about the axis, the proximal end of the blade precedes the distal end of the blade and wherein a substantial portion of each blade is curved to provide sufficient suction in the event the particulate material is difficult to move or the vacuum pickup hose connected to the air-material separating chamber is blocked. - View Dependent Claims (10, 11)
