Abstract: A centrifugal microstrainer includes a closed cylindrical vessel with a cylindrical screen within, both rotating about a hollow shaft forming a common central axis. Liquid-solid admixture introduced through the shaft is flowed radially outward subjected to centrifugal acceleration, and forced back through the screen under pressure with particles too large to pass the screen remaining on its outboard side. The centrifugal force applied by the rotation of the vessel acts on these larger particles pushing them away from the screen thus preventing clogging and permitting substantially continuous operation. The device may be operated as a classifier by providing a plurality of concentric screens of decreasing mesh size spaced outwardly from one another in conjunction with properly sized chokes.

Abstract: In a horizontal centrifugal separator there is included a housing that rests by means of cushioned supports upon the ground, foundation, or the like, with the housing providing for the bearing mounting of a shaft that connects with a revolvable bowl, with both of said shaft and bowl being arranged substantially along a horizontal axis; the bowl includes a series of vanes extending from its interior surface, arranged between its base and the rim portion, with the rim portion having a series of perforations therethrough so as to allow for separation of the coolant from the metal chips as accumulated in the metal working industry. A chute also mounts upon the housing and has its discharge end extending into the bowl, and further includes a deflector that is arranged approximate its end, and therein allows for the continuous delivery of chips to the bowl and their uniform distribution along its interior surface to facilitate the centrifugal separation of any coolant from the chips.

Abstract: A method for releasing compacted sugar crystals from a screen after centrifugation uses braking force for stopping rotation of the centrifuge. The brake stops rotation of the screen without simultaneously stopping rotation of the crystals accumulated adjacent the screen. The centrifuge may include one or more apertures in the base of the drum for exit of the sugar crystals.

Abstract: Centrifugal filter press with axial feed moves the material outwardly to at least one annular peripheral filter, via a plurality of oppositely opening conical surfaces. The net axial thrust in one direction is thus reduced, at the same time that the filter can be positioned desirably far from the bearings and the liquid outlet can have a venturi effect that educts what could otherwise be harmful fumes from the vicinity of the bearings.

Abstract: A continuously operating centrifuge for producing a high purity sugar or sugar syrup, has an acceleration bell or cone which acts as a preliminary separator, and a centrifugal basket, the lower portion of which acts as a washing stage. A damming ring is spaced from the upper edge of the basket to form with said upper edge a sugar exit gap. A discharge ring is arranged to cooperate with the damming ring. The discharge ring rotates with the basket, but about an axis extending at an angle relative to the rotational axis of the basket, whereby the actual sugar exit is confined to a predetermined zone along said sugar exit gap. A flow channel cooperates with said zone to receive the sugar without damage to the sugar crystals.

Abstract: The present centrifuge is especially adapted for centrifuging massecuite in the production of sugar. Two functional and structural units are separated from each other in such a manner that each unit may be supported independently of the other unit, yet so as to properly cooperate with each other. Thus, an inner housing and the rotating drum with the drive means for the drum form an inner, integral unit while an outer housing and a cover as well as the massecuite supply means form a further, outer integral unit. A carrier member, preferably in the form of a hollow channel, extends from the inner housing through the outer housing to support the drum drive means outside of the outer housing, but as part of the inner unit.

Abstract: Primary explosives, e.g. lead azide, dispersed in a liquid medium, e.g. enol, are filtered, washed and dried in a novel centrifuge, wherein the rotatable extractor basket has an open bottom, which is closed by peripheral attachment to the large open end of an invertible funnel. The small open end of the funnel is attached to an axial shaft, which can be raised and lowered, whereby said small open end can be held upright to retain the contents in said basket and lowered to invert the funnel to discharge the dried free-flowing explosive particles by gravity through said small open end.

Abstract: This invention is concerned with axial conveying of sludge through a stationary tube from inside to outside a rotating centrifuge. It incorporates a high speed auger screw to move the material. High speed implies spinning of the auger too fast for sludge adhesion, and operating the auger only partially full. The feed to the auger is by an unrestrained jet of material from which any material not driven axially by the auger is permitted to fall freely away from the auger feed section. The combination of high rotational forces, open ballistic feed, and partially full screw, combine to assure transport of thixotropic materials.

Abstract: Continuously operable sugar centrifuge comprises a number of centrifuging channels forming part of a conical frustum and being symmetrically distributed relative to a rotational axis. Preferably, two channels are arranged to receive the massecuite through massecuite supply conduits connected to the upper ends of the centrifuging channels. The lower ends of the centrifuging channels are connected through radially extending sugar discharge conduits leading to a sugar outlet arranged coaxially with the drive shaft of the centrifuge. The sugar conduits have a radial dimension so that their outer ends extend outside of the centrifuging channels. The outer ends of the sugar conduits are provided with funnels facing with their open face in the direction of rotation of the centrifuge whereby an air stream transports the sugar radially inwardly from the centrifuging channels to the sugar outlet.

Abstract: An integrated system for the separation of liquid and solids entrained in a carrier effluent including a primary gross oil and solids separator, a secondary solids separator and a three stage centrifuge for final separation of fine solids and said entrained liquid from the carrier effluent.

Abstract: A method of operating a filter centrifuge or centrifugal filter in which a hydrostatic head is provided at the filtering surface so as to control liquid passage therethrough. The head may promote movement of the liquid through the filter layer or may induce reverse flow of liquid for backwashing or rinsing. In addition, a hydrostatic balance may be provided at this surface through control of the head to limit passage of the liquid through the filter layer. Preferably the head provides a suction augmenting centrifugal filtration.
