Abstract: The present invention is a centrifuge device which separates chips or shreds of containers from whatever liquid residue remains within these containers. Though this technology is suitable for a number of applications, a primary objective is the separation of the recyclable plastic of a motor oil container from the remaining re-usable motor oil within the container after the container has ostensibly been emptied. It is an objective to accomplish this in an economically advantageous manner which uses neither a solvent nor a wash process, and which reclaims the oil in a suitable form for reprocessing. In its preferred embodiment, the present invention may be utilized as a compact, free-standing size reduction and reclaiming device at the location where the container is used, such as in automotive service stations, and the like. In a second embodiment, production units may be used in plastic reclaiming plants where large quantities of a given plastic container are being centrally processed.

Abstract: A centrifugal separator of the type comprising a bowl having a base and a peripheral wall surrounding a vertical axis about which the bowl rotates and a jacket having a base plate under the base of the bowl and a sleeve surrounding the peripheral wall includes a central bottom discharge for the concentrate. The bowl is mounted on the shaft with a hub connecting the shaft to the base plate of the jacket. Water is supplied through the shaft and through a pair of ducts passing through the hub and into the area of the base of the bowl. The discharge also extends through the hub through a pair of ducts which diverge from the central discharge opening outwardly and downwardly into a collection chamber. The discharge duct portions through the hub are angularly offset from the water supply duct portions through the hub so that both can be formed in the hub.

Abstract: The device comprises a closed chamber (1) equipped with an inlet pipe (3) for the aerated liquid, an outlet pipe (4) for the deaerated liquid, and an air evacuation pipe (5); and a rotor having a shaft extending into the chamber. The shaft carries means (7) for centrifugation of the liquid and means (8,9,10) for intensive agitation of the centrifuged liquid.The device works according to the following process: continuously, the liquid is introduced into the closed chamber and it is vigorously centrifuged there in with the aid of mechanical means (7) and simultaneously subjected to intensive agitation with the aid of second mechanical means (8,9,10).The released air gathers freely at the center of the chamber whence it is evacuated, as the deaereated liquid is evacuated through the outlet pipe.

Abstract: A method and apparatus provide for the effective centrifugal washing and/or thickening of paper pulp, using a perforated cylinder. A stock head box, located within the cylinder, applies a thin sheet of pulp on the interior the cylinder, at a high rate (e.g. about 20 meters per second), at a first arcuate position. The cylinder is rotated at high speed (e.g. 100 rpm, to provide an acceleration on the order of about 10 gs), whereby centrifugal force causes liquid in the pulp to move radially outwardly through the openings in the screen cylinder. The pulp is withdrawn from the interior of the cylinder by a vacuum roll or the like at a second arcuate position less than 360.degree. from the first position. The withdrawn pulp is moved by a screw conveyor or the like away from the cylinder in a dimension generally parallel to the axis of rotation, and the withdrawn liquid passes through channels in a drum surrounding the perforated cylinder, and is engaged by an impeller, and flows to a volute for removal.

Abstract: A non-blinding filter system for batch centrifuges utilizes a high speed injection nozzle to input wet particulate matter in the form of a slurry into a batch centrifuge in a manner that maintains turbulence within the slurry during the filling operation. Submicron particulate fines are suspended in the filtrate and settle out less rapidly than larger diameter particulate matter, thus a layer of coarser material can be laid over the filter media before the majority of the filtrate passes therethrough. A plurality of metering orifices retard the extraction of the filtrate such that the submicron particles are not forced through the layer of coarser material to the filter media with blinding consequences.

Abstract: A centrifugal filter separator system operable to separate from oil under pressure, contaminants and water. The centrifuged water port of the centrifugal filter separator of the system is coupled to a differential pressure responsive, sensor control, which automatically senses the presence of a layer of centrifuged water against the internal surface of the rotating drum of the centrifugal separator. The sensor control is coupled to a flow control circuit which in conjunction with the differential pressure sensor control causes automatic removal of an existing layer of centrifuged water from the rotating drum via the water exit port of the separator. When there is no adequate depth layer of centrifuged water on the inner surface of the rotating drum, the sensor control deactivates the water removal circuit, while the flow control circuit maintains a minimum generally constant flow of liquid from the water port of the separator for priming purposes.

Abstract: A centrifugal filter separator system operable to separate from oil under pressure solid contaminants, by depositing them on the internal wall of a rotating drum, powered by reaction jet nozzles, while also separating water from oil and extracting it from the rotating drum through a water extraction circuit. A water-oil mixture from the water extraction circuit is passed through a pressurized gravity type separator, from which the separated oil is returned, on a continuous basis, back to the centrifugal filter separator system, while the quantity of the water retained in the gravity type separator is controlled by a water ejecting automatic control, responsive to the position of the water-oil miniscus, or to the position of the layer of water-oil emulsion separating water and oil within the separator.

Abstract: A centrifugal filter separator system operable to separate from oil under pressure solid contaminants, by depositing them on the internal wall of a rotating drum, powered by reaction jet nozzles, while also separating water from oil and extracting it from the rotating drum through a water extraction circuit. A water-oil mixture from the water extraction circuit is passed through a pressurized gravity type separator, from which the separated oil is returned, on a continuous basis, back to the centrifugal filter separator, while the water is retained in the gravity type separator. Flow of the mixture of water and oil through the extraction circuit is regulated in respect to change of viscosity of the extracted liquid, but relatively independent of pressure within the rotating drum for maximum efficiency of the gravity type separator.

Abstract: A method and apparatus are disclosed for extracting finished juice from an initial juice including substantial solids or for extracting fluid, preferably finished to a high degree, from any slurry including substantial solids, wherein the slurry is introduced into one end of a cylindrical screen, the cylindrical screen being driven in rotation for centrifugally urging the slurry against the screen and causing fluid from the slurry to pass through the screen.

Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing and a rotor within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor, air under pressure is supplied to the interior of the casing by means of a float-operated valve member so that while the valve member is normally closed, any increase in the oil level will cause the float to rise with that oil level and thereby open the valve to allow additional air to enter into the interior of the casing.

Abstract: A continuously operable sugar centrifuge modified as taught herein is capable of producing quality sugar. For this purpose elastic, spring resilient sheet metal members (11) are attached to a rotatable ring with an adjustable angle of incidence so that the surface of these flexible sheet metal members encloses a selectable incidence angle with the flight path (12) of the sugar crystals, whereby the speed with which the sugar crystals impinge on the flexible sheet metal members may be controlled. Such control may be accomplished, for example, by a closed loop deceleration or braking action of the rotatable ring carrying the metal members.

Abstract: A centrifugal separator, especially a pusher centrifuge is disclosed, wherein at least one rotatable sieve or filter drum is mounted within a housing. Within the sieve or filter drum there is arranged a to-and-fro displaceable pusher or thrust element, for instance in the form of a pusher floor member, which serves for displacing solid materials in the form of a filter cake towards outlet or discharge openings for the treated product. To process thin suspensions with the pusher centrifuge the pusher floor member is arranged for oscillating movement between two turning or deflection points preferably located at the region of an imaginary central line of the sieve or filter drum. A feed or supply pipe for the infeed of the suspension which is to be separated extends substantially coaxially with respect to the sieve or filter drum and its outlet or outflow opening, which extends radially outwardly, is located essentially at the center between the turning or deflection points of the pusher floor member.

Discharge means positioned in the cylindrical side wall portion (16) extend radially into the interior of the bowl (12) for discharging the lighter phase fluid.

Abstract: A continuously operable sugar centrifugal for mixing and curing sugar massecuites includes an intermediate mixing device between inner and outer centrifugal baskets. The mixing device is formed by a ring housing with an impact zone, retaining zone, and inclined baffles to impart turbulence and transform the kinetic energy of sugar received from the inner basket into the work of mechanical mixing. Mixing liquid is introduced into the received sugar and the mixture eventually passes over the lower edge of the mixing device into the outer basket for final separation and curing. The mixing device is stationary relative to the inner basket or rotates at a slower speed and may assume a variety of advantageous geometries.

Abstract: The present continuously operating centrifuge produces sugar of uniformly high quality from low grade sugar massecuite of uneven consistency by distributing the massecuite to differing selected levels of a centrifugal screening basket. The distribution level depends on the liquid content characteristics of the massecuite. An accelerating cup is mounted for rotation centrally within the basket for receiving and delivering massecuite to a distributing bell opening downwardly and surrounding the accelerating cup. The distributing bell directs the massecuite toward the tapering wall of the centrifugal screening basket. The lower edge of the distributing bell is vertically adjustable relative to a lower zone of the screening basket for said distributing of the massecuite to different levels of the basket. The centrifugal basket may have several zones.

Abstract: A separator for separating liquids immiscible with each other and containing solids heavier than the heavier liquid, includes a rotating conic drum into which the liquids are injected. The drum has a circumferential wall formed of two oppositely-directed conic surfaces joined at the bases at an inclination angle to form an equator; and openings are provided at the equator for the heavier liquid and the solids to pass. Preferably, the drum has a star-like cross section with the interior wall extending inward at an angle from either side of each opening. The separator can include a weir or paring disc disposed radially in the static pressure chamber at a nominal level of the heavier liquid to maintain proper pressure of the heavier fluid to prevent the lighter liquid from discharging into the static pressure chamber. Alternatively, a sensor and valve arrangement can be provided to achieve this benefit.
