Description
Verfahren und Vorrichtung zum Filtrieren von sich -schnell absetzenden Schlammflüssigkeiten Die Erfindung betrifft ein Verfahren und eine Einrichtung zum Betrieb von Trommeldrehfiltern, die im Scheitel beaufschlagt werden, insbesondere solchen, die zum Filtern von sich schnell absetzenden und auf dem Filterumfang Krusten bildenden Filtermassen dienen.Method and device for the filtration of rapidly settling Sludge liquids The invention relates to a method and a device for Operation of rotary drum filters that are acted upon in the apex, in particular those used to filter crusts that settle quickly and on the perimeter of the filter forming filter media are used.
Es ist bereits ein Verfahren zum Betrieb von Trommelfiltern bekannt, bei dem der im Filtertrog befindliche Schlamm teilweise dem Trog entnommen und auf den nicht in den Trog eintauchenden Teil der Filterfläche verteilt wird. Dieses Verfahren dient dazu, die Bildung der Filterkuchenschicht auf der Trommel zu begünstigen und den Filterkuchen zu verstärken. A method for operating drum filters is already known, in which the sludge in the filter trough is partially removed from the trough and on the part of the filter surface that is not immersed in the trough is distributed. This The method is used to promote the formation of the filter cake layer on the drum and to strengthen the filter cake.
Das Neue nach der Erfindung besteht demgegenüber darin, daß das Rohgut in. ununterbrochenem Kreislauf gehalten wird, von dem das zu filtrierende Rohgut in einem regelbaren Zweigstrom auf die Filtertrommel geleitet wird. Zur Ausführung des Verfahrens soll in den Kreislauf des Rohgutes eine an sich bekannte Mischluftpumpe und ein Verteilkasten mit verstellbarer Klappe für die Ableitung des Rohgutes-nach der Filtertrommel eingebaut sein. The novelty according to the invention consists in the fact that the raw material is kept in. Uninterrupted cycle, of which the raw material to be filtered is passed in a controllable branch stream onto the filter drum. For execution In the process, a known mixed air pump is to be introduced into the cycle of the raw material and a distribution box with adjustable flap for diverting the raw material to installed in the filter drum.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung schaubildlich dargestellt. An exemplary embodiment of the invention is shown diagrammatically in the drawing shown.
Abb. I zeigt den Kreislauf des Rohgutes und die Regelvorrichtung für. das aufzugebende Rohgut; Abb. 2 stellt den Verteilkasten mit Regelvorrichtung dar. Fig. I shows the cycle of the raw material and the control device for. the raw material to be abandoned; Fig. 2 shows the distribution box with control device represent.
Gemäß Abb. I ist mit I der Vorratsbehälter für das zu filtrierende Rohgut bezeichnet. According to Fig. I, with I is the storage container for that to be filtered Called raw material.
Dieses strömt in das Abfallrohr 2 und wird mittels der Mischluftpumpe 3 durch die Leitung 4 in den Verteilkasten 5 gefördert. Von hier fließt ein Teil des Filtergutes in den Behälter I zurück, während der übrige Teil des Rohgutes durch Leitung 6 zur Aufgabe auf die Filtertrommel 7 gelangt. Dieser Teil ist regelbar mittels der Klappe 8, welche je nach ihrer Einstellung mehr oder weniger Rohgut in die Leitung 6 gelangen läßt.This flows into the waste pipe 2 and is by means of the mixed air pump 3 promoted through the line 4 into the distribution box 5. Part of it flows from here of the filter material back into the container I, while the remaining part of the raw material through Line 6 reaches the task on the filter drum 7. This part is adjustable by means of the flap 8, which, depending on its setting, more or less raw material can get into the line 6.
Der Vorteil dieses Scheitelfilters besteht darin, daß beispielsweise bei sich schnell absetzenden Schlammflüssigkeiten und einem Rohgut mit hohem Feststoffgehalt ein unerwünschtes Absetzen von Feststoffteilen vermieden wird, weil das Rohgut sich in ununterbrochenem Kreislauf und außerdem durch die Mischluftpumpe in stetiger Durchmischung befindet. The advantage of this crest filter is that, for example in the case of rapidly settling sludge liquids and a raw material with a high solid content unwanted settling of solid parts is avoided because the raw material in an uninterrupted cycle and, moreover, in a steady manner thanks to the mixed air pump Mixing is located.
PATENANSPRÜCRE: I. Verfahren zum -Filtrieren von sich schnell absetzenden Schlammflüssigkeiten mittels Trommeldrehfilter, die im Scheitel beaufschlagt werden, dadurch gekennzeichnet, daß das Rohgut in ununterbrochenem Kreislauf gehalten wird, von dem das zu filtrierende Rohgut in einem regelbaren Zweigstrom auf die Filtertrommel geleitet wird. PATENT CLAIMS: I. Method for filtering rapidly settling Sludge liquids by means of rotary drum filters, which are acted upon in the apex, characterized in that the raw material is kept in an uninterrupted cycle, from which the raw material to be filtered is transferred to the filter drum in a controllable branch flow is directed.
