Description
Fü11- und Entleerungsvorrichtung für in geschlossenen Gehäusen mit Über-und Unterdruck arbeitende umlaufende Planfilter.Fü11- and emptying device for in closed housings with Circulating flat filters working over and under pressure.
In geschlossenen Gehäusen mit Über- und Unterdruck arbeitende umlaufende Planfilter entsprechen nur dann allen Anforderungen, wenn sie kontinuierlich arbeiten, d. h. wenn die Aufgabe des zu filtrierenden Gutes und die Entnahme der Rückstände keine Unterbrechung des Betriebes erfordert. Circulating in closed housings with positive and negative pressure Plan filters only meet all requirements if they work continuously, d. H. if the abandonment of the material to be filtered and the removal of the residues does not require any interruption of operation.
Gemäß der vorliegenden Erfindung sind Planfilter der erwähnten Art für den kontinuierlichen Betrieb derart eingerichtet, daß sowohl der Einführungskanal für das zu filtrierende Gut als auch der Abführung kanal für die Rückstände durch in Abhängigkeit voneinander sich drehende Kammer- oder Zellentrommeln nach außen stets dicht abgeschlossen ist, so daß weder der ueberdruck oberhalb des Filtertisches noch der Unterdruck unterhalb des Filtertisches beeinträchtigt wird. According to the present invention, planar filters of the type mentioned are set up for continuous operation in such a way that both the introduction channel for the material to be filtered as well as the discharge channel for the residues Chamber or cell drums rotating outwards depending on one another is always tightly sealed, so that neither the overpressure above the filter table nor the negative pressure below the filter table is impaired.
Auf der Zeichnung ist der Erfindungsgegenstand im Vertikalschnitt zur Darstellung gebracht. The subject of the invention is shown in vertical section on the drawing brought to the display.
Der wagerecht umlaufende Filtertisch e, der durch den Steuerkopf b mittels der Anschlüsse c an eine Vakuumleitung angeschlossen ist, arbeitet in einem geschlossenen Gehäuser, in welches die beliebig zu steigernde Druckluft durch einen Stutzen e eingeführt wird. The horizontally rotating filter table e, the one through the control head b is connected to a vacuum line by means of the connections c, operates in a closed housing into which the compressed air, which can be increased as required, passes through a nozzle e is introduced.
Das zu filtrierende Gut wird dem unter Über- und Unterdruck arbeitenden Planfilter durch einen mit dem geschlossenen Gehäuse d verbundenen Einführungskanal g zugeführt, die Rückstände werden durch einen ebenfalls mit dem geschlossenen Gehäuse d unterhalb des Filtertisches a verbundenen Abführungskanal n abgeführt. The material to be filtered becomes that which works under positive and negative pressure Planar filter through an inlet channel connected to the closed housing d g, the residues are also fed through with the closed housing d below the filter table a connected discharge channel n dissipated.
Beide Kanäle, sowohl der Einführungskanal g wie der Abführungskanal n, enthalten drehbare Kammer- oder Zellentrommeln h, die die Kanäle nach außen dicht abschließen. Both channels, both the inlet channel g and the discharge channel n, contain rotatable chamber or cell drums h that seal the ducts to the outside to lock.
Die durch Kettenräder i oder in anderer geeigneter Weise angetriebenen Kammer- oder Zellentrommeln h bilden Schleusen, welche verhindern, daß der in dem Gehäuses oberhalb des umlaufenden Filtertisches a zur Geltung kommende Überdruck und der unterhalb des Filtertisches zur Geltung kommende Unterdruck während des Füllens und Entleerens eine Beeinträchtigung erfährt. Those driven by chain wheels i or in some other suitable manner Chamber or cell drums h form locks which prevent the in the Housing above the rotating filter table a coming into effect overpressure and the negative pressure that comes into effect below the filter table during the Filling and emptying experiences an impairment.
Die Abführung der Rückstände erfolgt in an sich bekannter Weise durch einen Abstreichschaber in Verbindung mit einer in dem Gehäuse d angeordneten Förderschnecke k. The residues are removed in a manner known per se a scraper in connection with a screw conveyor arranged in the housing d k.
Der Abstreichschaber ist in der Höhe einstellbar, so daß nach Bedarf eine dütme oder dicke Schicht des Filtergutes von dem Filterbelag des umlaufenden Filtertisches a abgenommen wird. Die Fördrrschnecke k führt die Rückstände in einen um den Filtertisch a herumlaufenden Sammelkanal t. In diesem Sammelkanal 2 bewegen sich in bekannter Weise Schaufeln m, die mit dem umlaufenden Filtertisch a verbunden sind. Mittels der Schaufeln werden die Rückstände aus dem Sammelkanal t in den Abführungskanal n überführt, aus dem sie durch die sich drehenden Kammer-oder Zellentrommeln k gedrückt werden.The scraper is adjustable in height so that as required a dutme or thick layer of the filter material from the filter lining of the circumferential Filter table a is removed. The conveyor screw k feeds the residues into one collecting duct t running around the filter table a. Move in this collecting channel 2 in a known manner blades m, which are connected to the rotating filter table a are. The residues are removed from the collecting channel t into the discharge channel by means of the blades n transferred from which it is pressed by the rotating chamber or cell drums k will.
Das Gehäuse d trägt oberhalb des umw laufenden Filtertisches a ein Manometer, unterhalb des Filtertisches ein Vakuummeter zur Feststellung und Regelung des Über- und Unterdruckes. The housing d enters above the rotating filter table a Manometer, below the filter table a vacuum meter for detection and control of overpressure and underpressure.
Der Antrieb des Filtertischesa kann durch Stirn-, Kegel- oder Schraubenräder in geeigneter Weise erfolgen. The filter table can be driven by spur, bevel or helical gears done in a suitable manner.
