Abstract:
A machine tool coolant filtering system (10) is disclosed as including a plurality of coolants filter tanks (12a), (12b), (12c). Each filter tank (12) is designated for receiving coolant carrying a different material contaminant. A pipe network (20) and pipe branches (24) control communication of coolant to the coolant filter tanks (12). Liquid level within respective tanks (12a), (12b), (12c). Modulating valves (46) in communication with the liquid level sensors (40) control outflow from the respective tanks (12a), (12b), (12c). The coolant filtering system (10) segregates different material contaminants carried by common machine tool coolants for recycling.

PCT No. PCT/AT92/00162 Sec. 371 Date Jun. 2, 1994 Sec. 102(e) Date Jun. 2, 1994 PCT Filed Dec. 7, 1992 PCT Pub. No. WO93/11851 PCT Pub. Date Jun. 24, 1993.In an apparatus for separating particulate material from a particle-containing liquid, at least the section of the cylindrical housing (10) provided with perforations (5) is designed as a driveable drum sieve (2') so that the solid materials are optimally separated from the liquid phase and are at the same time freed from particulate impurities.
Abstract:
An improved conveyor system for machine tool cleaning applications comprises a sump internal to a machine tool, a recirculating system in fluid communication with the sump, a hinge belt conveyor, portions of which are interposed between the sump and the recirculating system for removing coarse solids from the fluid, and a fine filter interposed between the sump and the recirculating system for removing fine solids from the fluid.
Abstract:
An improved screen plate for a pressure screening apparatus and a method for making the basket are disclosed wherein prestressed areas are provided at each end of each slot formed in the screen plate for minimizing crack propagation.
Abstract:
A thickener for fiber suspensions and the like includes a plurality of rotatable filter disks (3) mutually spaced in axial direction and being adapted to be partially submerged in a liquid or suspension (5) to be filtered. Each filter disk comprises a plurality of filter sections (4) communicating with axial ducts (2) at the outer peripheries of the filter disks (3) for removal of filtrate. The axial filtrate ducts (2) are open to the atmosphere at at least one end (2') thereof for the purpose of conducting air through these ducts into the interior of the filter sections to replace the filtrate flowing out. Advantageously, there is communication between all filtrate ducts through the annular filter disk holder (1) which carries each filter section (4).
Abstract:
Filtering sector intended to form a filtering disc comprising a rigid frame imparting the form thereto, filtering cloth supports inside the frame and a connection part for connecting a rotary filter to a hollow drive shaft (2), said shaft containing connectors of liquid and gas fluids, the sector being characterized in that its internal thickness increases from the peripheral end thereof (14) up to the end (15) thereof at the vicinity of the hollow drive shaft (2).
Abstract:
A water separation group (1) for a fuel filtration and separation assembly (900) of a fuel circulation system of a vehicle, wherein the assembly (900) extends along a longitudinal axis (L-L) positionable in the vehicle in a horizontal position comprising a filtration group (500). The water separation group (1) is associable to the filtration group (500) for receiving filtered fuel, being positionable in a serial mode along the longitudinal axis (L-L). The water separation group (1) comprises: - a main body (10) which delimits therein a separation chamber (100) and comprises, at an axial end, an outlet wall (12) on which it comprises at least one outlet mouth (120); - a separator device (2) accommodated in the separation chamber (100); - a blocking device (3) positioned below the separator device (2) to prevent the return of the water to the separator device (2). The blocking device (3) comprises a blocking surface (31) which extends in a longitudinal direction forming an angle that inclines at least a portion of said blocking surface (31) so as to allow the water separated from the fuel to flow towards the outlet wall from which extends.
Abstract:
Eine zur Gewinnung von Filtrat aus Abwässern bestimmte Filtrationsvorrichtung ist durch ein innerhalb eines Flüssigkeitsbades in einem Becken (1) um eine horizontale Achse (5) drehend antreibbares Rotorsystem (2) gekennzeichnet, welches als Träger mehrerer Anordnungen (17) von Filterscheiben dient, deren Innenräume über eine Sammelkammer (29) mit der Saugseite einer Pumpe (39) in Verbindung stehen. Eine Zufuhr an zu filternder Flüssigkeit erfolgt unter Mitwirkung einer Pumpe (40), die über eine Leitung (31) unter Zwischenanordnung eines zur Abtrennung einer Grobfraktion bestimmten Vorfilters (41) mit mehreren, sich parallel zu und in der Nähe der das Rotorsystem (2) tragenden Hohlwelle (21) erstreckenden Verteilerlanzen (35) in Verbindung steht. Infolge der zentralen, über die Länge des Rotorsystems (2) über die Verteilerlanzen (35) in gleichförmiger Verteilung erfolgenden Einführung der vorgefilterten Flüssigkeit in Verbindung mit einem in dem Becken (1) bodenseitig befindlichen Netzwerk (36) aus zur Einführung von Luftblasen in das Flüssigkeitsbad bestimmten Leitungen ergibt sich ein stabiler, die Bildung von Ablagerungen unterdrückender, somit eine hohe gleichmäßige Filterleistung mit sich bringender Betrieb.
Abstract:
An oscillating shower (30) for use with a disc filter. The disc filter includes at least one disc (2) and oscillating showers that periodically remove a precoat layer of solids from the surface of the disc. Each oscillating shower (30) moves over the surface of the disc (2) at a varying speed so that water is uniformly applied to the interior and exterior of the disc. At the interior of the disc, where there is a smaller surface area, the oscillating shower moves faster than at the exterior of the disc where the surface area is greater.
