Centrifuge for Oil-Tarsand Separation (Patent No: 533236)

Inventor: Christenson, John Ludvik (assignor)

Location: Edmonton

Comments: N/A

Description: I CLAIM:

1. In a centrifuge, a main support, a hopper member provided with a series of concentrically arranged fluid outlet openings rotatably mounted on the main support, a cover member provided with a material feed inlet releasably connected to the hopper member, discharge doors arranged around the outer periphery of the cover member operatively reacting to the influence of centrifucal force to permit the discharge of solids from the hopper, means for rotatably supporting the hopper, a spreader cone concentrically disposed in said hopper, spring actuated means for the discharge doors, and a catch basin for receiving the separated fluids.

2. In a centrifuge, a main support, a hopper member rotatably mounted on the main support, an intruded hub for the base of the hopper provided with a series of fluid outlet openings, a cover for the hopper provided with a material feed inlet, spring actuated discharge doors arranged around the outer periphery of the cover member operatively reacting to the influence of centrifugal force to permit the discharge of solids from the hopper, means for rotatably supporting the hopper, a spreader cone centrifically disposed in said hopper, and a catch basin for receiving the fluids discharged through the said outlet openings.

3. In a centrifuge, a main support, a hopper member provided with a series of fluid outlet openings rotatably mounted on the said support, a spreader cone concentrically disposed in the hopper, a cover for the hopper member provided with a material inlet and a series of discharge doors, the said doors reacting to the influence of' centrifugal force to permit the discharge of solids from the hopper, means for rotatably supporting the hopper, spring actuated means for the discharge doors, and a catch basin adapted to receive separated fluids discharged through the fluid outlet openings.

4. In a centrifuge as set forth in claim 1 wherein the discharge doors are provided with adjustable spring actuating means.

5. A centrifuge according to claim 3 wherein the discharge doors are normally retained in closed position by adjustable spring means.

6. A centrifuge according to claim 1, 2 or 3 wherein the main support is provided with a hub having a dished outwardly extending rim at its base to form an oil shed or drip edge.
