Abstract:

A self-cleaning apparatus for sorting a mixture of materials is disclosed that comprises a material sorter and a gantry positioning system elevated above the material sorter. The gantry positioning system includes a longitudinal travel rail with a longitudinal travel rail carriage, a traverse travel rail connected to the longitudinal travel rail carriage running perpendicular to the longitudinal travel rail, with a traverse travel rail carriage, and a vertical travel rail connected to the vertical travel rail carriage running perpendicular to the traverse travel rail. A cutter and optionally, a picker, are connected to the vertical travel rail. The gantry positioning system can move the cutter and picker various directions to dislodge and remove material that may have accumulated on the sorter. Instead of a gantry positioning system, the apparatus may have a multi-axis arm.

Appl. No.:

14/797093

Inventors:

Nicholas Davis - San Diego CA, US
Robert Davis - Jamul CA, US

Assignee:

CP Manufacturing, Inc. - San Diego CA

International Classification:

B07B 4/06

Abstract:

A rotating suction chamber apparatus for sorting a mixture of materials comprises a cylindrical drum with its upper end is at a higher elevation than its lower end. An upper housing connected to the upper end has a material intake for receiving the mixture of materials for introduction to the upper end. The mixture of materials includes a light fraction and a heavy fraction, and the upper housing has an outlet for the light fraction. A suction hood connected to the light fraction outlet includes a light separator shaft with a substantially vertical portion, and an air blower is adapted to create an airflow from the lower end, to the upper end, through the light fraction outlet and through the suction hood. A rotator rotates the drum about its longitudinal axis so that the heavy fraction is moved through the drum and falls out of the lower end.

International Classification:

B07B 1/15
B29C 45/26

Abstract:

A new and novel disc for use in a disc screen apparatus is disclosed. In one embodiment, the disc comprises a hub having a central bore, and a plurality of impacting arm elements extending radially therefrom, each of the impacting arm elements comprising an impacting arm and an impacting arm end portion, the impacting arm elements configured for engaging materials to be classified and propelling the materials in a conveying direction when the hub is rotated, at least some of the impacting arm elements comprising texturing imposed on a surface of one of the end portions for engaging the materials as the hub is rotated.

Appl. No.:

14/809238

Inventors:

Nicholas Davis - San Diego CA, US

Assignee:

CP Manufacturing, Inc. - San Diego CA

International Classification:

B07B 1/15

Abstract:

A disc for use in a disc screen is disclosed that creates an “intended space”—i.e., the designed space through which material is intended to pass—that undulates in both directions in the plane defined by the screen's rotatable shafts. The disc design includes a major axis that is rotated along the length of the shaft, creating a helical ridge. The ridge is continuous and non-stepwise, thereby avoiding the “pinch” of the prior art designs. And by having the helical ridge of adjacent discs on the same shaft with opposing rotations, the lateral movement of material may alternate along the length of the shaft—further spreading the material throughout the width of the disc screen and increasing the screen's efficiency.
