摘要:
A filter that comprises a stack of filter discs within its housing with the side faces of the discs formed with surfaces effective to filter the fluid flowing between them from the housing inlet to the outlet, according to one embodiment of the present invention, at least some of the discs being formed with a serrated edge at the upstream side of the stack facing the housing inlet, which serrated edges are effective to increase the upstream filter surface and also to form pockets for receiving dirt particles. According to another embodiment of the present invention, the thickness of each of the filter discs is smaller at its upstream side than at its downstream side, and/or the depth of their grooves is larger at the upstream side than at the downstream side, such that the upstream side of the stack of filter discs is formed with pockets between adjacent discs, in addition to said grooves, for receiving and holding foreign particles separated from the fluid.

57 Cartridge filter, (12) particularly for water, to be either connected or not with water cleaners, (56, 57) with valve device (16) and two positions: on of them can allow the passage of the fluid through the filtering cartridge and the other enables the connection directly between the inflow and outflow bores by excluding the filtering cartridge which can be easily cleaned or replaced.
摘要:
Le filtre comporte un corps de filtre globalement cylindrique (10), à tubulure d'entrée latérale droite (11) et tubulure de sortie axiale (12), et une crépine fixe (13), qui, disposée dans ledit corps de filtre (10), est globalement excentrée suivant l'axe de ladite tubulure d'entrée (11). Suivant l'invention, entre la crépine fixe (13) et le corps de filtre (10), l'espace interne est diamétralement partagé en deux volumes distincts (A, B), suivant le plan axial (P) du corps de filtre (10) contenant l'axe (A2) de la tubulure d'entrée (11), chacun desdits volumes (A, B) s'étendant respectivement de part et d'autre de la crépine fixe (13), de la tubulure d'entrée (11) à une zone de récupération de débris (22A, 22B) distincte diamétralement opposée à celle-ci. Application, notamment, à la filtration d'eaux industrielles.
摘要:
In einem Verfahren zur kontinuierlichen Eindickung von Suspensionen in einem Filtereindicker mit herausnehmbaren kerzenförmigen Filterelementen (15), die an einzelnen Sammelrohren hängend befestigt sind, werden ohne Unterbrechung der Filtration einzelne Segmente durch Rückspülen mit Druckgas abgereinigt. Das gasförmige Ruckspülmittel bildet über den Filterelementen einen von der Flüssigkeit abgetrennten Gasraum mit einstellbarem Druck, der während des Betriebes weitgehend konstant gehalten wird. Die Konstanthaltung des Druckes erfolgt über eine Niveauregelung (12) der Flüssigkeit im Filterbehälter (1). Durch rasche Reinigungszyklen kann während der Filtration auf Filterhilfsmittel weitgehend verzichtet werden. Als Filterhilfsmittel kann jedoch der eingedickte Schlamm dienen. Dieser wird durch Druckluft mittels Mammutpumpe in ein Steigrohr (41) getrieben und nach seinem Austritt auf die Filterelemente (15) aufgebracht oder in einem Rohrteil (46) unterhalb des Konus (2) gewaschen und über eine Schleuse (50) automatisch ausgetragen. Das Verfahren eignet sich in besonderer Weise zur Reinigung von Sole vor und nach der Elektrolyse; zur Filtration von Rotschlamm zwecks Befreiung von Natronlauge; zur Filtration von Viskose und Zuckerdünnsäften, sowie zur Kondensatreinigung und Reinigung von PVC-Abwässern.
摘要:
A low pressure filtration and thickening device comprising a tank 11 having a plurality of suspended filter elements 12 therein and a plurality of filtrate receiving compartments 21 in the upper portion of the tank for receiving filtrate from the filter elements. The filtrate discharge systemprovides separate and uninterrupted flow paths for the filtrate from each compartment 21 to a storage tank. Each such flow path has a discharge pipe 29, riser 30, and individual box 31 in a head box 32.
摘要:
A pressure filter for separating a liquor from mud liquor slurry and for concentrating a filter cake as a heavy slurry discharge, comprising a tank 11 having a ring of filter elements 15 supported by a plate 16 which separates the filter tank from a filtrate chamber 20. The feed enters the tank under pressure through an enlarged feed cylinder tube 29 located in the centre of the ring of filter elements. In the backwashing mode of operation the feed rate is maintained or increased to assist in displacing filter cake from the filter element.
