Description
Vorrichtung zum Ausfiltrieren von Feststoffen aus Flüssigkeiten Die Erfindung bezieht sich auf eine Vorrichtung zum Ausfiltrieren von Feststoffen aus Flüssigkeiten, in der zur Aufnahme von Filtergut, Waschflüssigkeit und ausfiltrierten Feststoffen um eine lotrechte Achse Behälter angeordnet sind, welche die lotrecht an den Filterrohren angebrachten, sternförmig um einen auf der Achse befestigten Steuerknopf drehbeweglichen Filterzellen durchwandern und besteht darin, daß die Rohre zur Ableitung des Filtrats bzw. der verbrauchten Waschflüssigkeit mit den Filterzellen von in vertikaler Richtung aus- und einfahrbaren Spindeln getragen werden.Device for filtering solids out of liquids the Invention relates to a device for filtering out solids Liquids in which to take up filter material, washing liquid and filtered out Solids are arranged around a vertical axis, which is perpendicular to the container attached to the filter tubes, fixed in a star shape around one on the axis Control knob rotatable filter cells wander through and consists in the fact that the Pipes for discharging the filtrate or the used washing liquid with the Filter cells carried by spindles that can be extended and retracted in the vertical direction will.
Bei der Vorrichtung nach der Erfindung sind die Filterzellen mit den zugehörigen Rohren und Spindem wahlweise einzeln oder in Gruppen am Steuer kopf anschließbar. In the device according to the invention, the filter cells are with the associated pipes and spindles either individually or in groups at the steering head connectable.
Es gehört weiter zu der Erfindung, daß das Filterzellenaggregat mit den Behältern in einem druckfesten Gehäuse untergebracht ist, dessen Innenraum durch Trennwände unterteilt ist. It is also part of the invention that the filter cell assembly with the containers is housed in a pressure-resistant housing, the interior of which is through Partitions is divided.
Unter der Bezeichnung Moore-Filter ist eine intermittierende Filtrationseinrichtung bekannt geworden, bei welcher mehrere Behälter zur Aufnahme von Filtergut, Waschflüssigkeit und ausfiltrierten Feststoffen in einer Reihe angebracht sind. An einer darüber angeordneten Bahn hängen die Filterrahmen und werden nacheinander in die Behälter eingelassen, um der verschiedenartigen Behandlung unterzogen zu werden. Diese Filterein- richtung läßt eine kontinuierliche Arbeitsweise mit hoher Leistung nicht zu. The Moore filter is an intermittent filtration device become known in which several containers for receiving filter material, washing liquid and filtered solids are arranged in a row. At one above arranged web hang the filter frames and are successively in the container admitted to be subjected to the various treatments. These filter elements direction does not allow a continuous operation with high performance.
Man hat auch schon die Behälter ukn eine lotrechte Achse angeordnet. Bei der bekannten Ausführung besteht jedoch die Filterfläche praktisch anus'einer durch Gelenke unterbrochenen Kreisringfläche. Die Rahmen sind waagerecht angeordnet und tauchen in dieser Anordnung in die Behälter zu der verschiedenartigen Behandlung ein. Die geringe Filterfläche hat naturgemäß ebenfalls eine ganz geringe Filterleistung zur Folge, obwohl ein großer Raum hierfür beansprucht wird. The container ukn has also been arranged on a vertical axis. In the known embodiment, however, the filter surface is practically anus'einer circular ring surface interrupted by joints. The frames are arranged horizontally and in this arrangement immerse themselves in the containers for the various treatment a. The small filter surface naturally also has a very low filter performance result, although a large space is required for this.
Eine andere bekannte Ausführung besitzt einzelne um eine lotrechte Achse kreisende Filterzellen, welche nacheinander die einzelnen Behälter für das Filtrieren, das Vorwaschen, Fertigwaschen und Trocknen durchwandern. Sie sind ebenfalls sternförmig an einem entsprechend ausgebildeten Steuerkopf angeschlossen und werden angehoben und abgesenkt, um von einem Behälter in den anderen zu gelangen. Diese Bewegung der Filterzellen erfolgt bei den bekannten Ausführungen durch Schwenlcen um einen Drehpunkt, wobei durch das Gelenlç das Filtrat, die Waschflüssigkeit u. dgl. abläuft. Dieses Schwenken der Filterzellen führt zwangläufig zu erheblichen Schwierigkeiten in der Filtration. Der Filterkuchen hat auf den Filterzellen bei ihrer vertikalen Schwenlçbewegung je nach dem Abstand vom Gelenk verschiedene Geschwindigkeit. Das führt zu Verwerfungen im Filterkuchen. Dabei löst sich der Filterkuchen vom Filtertuch und fällt in den Behälter zurück. Das ist insbesondere dann von Nachteil, wenn in einem zweiten Behälter eine Nachfiltration auf einem bereits langeschwemmten Filterkuchen erfolgt. Another known design has individual ones around a perpendicular Axis rotating filter cells, which one after the other the individual containers for the Filter, hike through the pre-wash, finish wash, and dry. You are too and are connected in a star shape to a correspondingly designed control head raised and lowered to move from one container to the other. These In the known designs, the filter cells are moved by pivoting around a fulcrum, whereby the filtrate, the washing liquid u. the like. expires. This pivoting of the filter cells inevitably leads to considerable Filtration difficulties. The filter cake has on the filter cells their vertical pivoting movement varies at different speeds depending on the distance from the joint. This leads to distortions in the filter cake. The filter cake comes off the Filter cloth and falls back into the container. This is particularly disadvantageous if in a second container a post-filtration on an already long-flooded one Filter cake takes place.
Die Vorrichtung nach der Erfindung besitzt die Mängel der bekannten Einrichtungen nicht. Dadurch, daß die Rohre zur Ableitung des Filtrats und der verbrauchten Waschflüssigkeit zusammen mit den Filterzellen von in vertikaler Richtung aus-und einfahrbaren Spindeln getragen werden, bleibt der Filterkuchen am Filtertuch in gleichmäßiger Stärke haften und läßt sich so von einem Behälter zum anderen weiter führen. The device according to the invention has the shortcomings of the known ones Facilities not. The fact that the pipes for discharging the filtrate and the consumed Washing liquid together with the filter cells from and out in the vertical direction retractable spindles, the filter cake remains on the filter cloth of uniform strength and can be passed on from one container to another to lead.
In der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung nach der Erfindung dargestellt. Es zeigt Abbc I eine schematische Darstellung des Weges, den die Filterzellen in einem Arbeitsgang zurücklegen, Abb. 2 eine Draufsicht auf ein zylindrisch gestaltetes Filtergehäuse, Abb,. 3 einen Querschnitt durch einen Druckfilter, Abb. 4 eine Teildraufsicht auf das Filtergehäuse und Abb. 5 einen Querschnitt dazu. In the drawing is an embodiment of the device according to of the invention shown. It shows Abbc I a schematic representation of the path, which the filter cells cover in one operation, Fig. 2 is a plan view a cylindrical filter housing, Fig. 3 shows a cross section through a Pressure filter, Fig. 4 is a partial top view of the filter housing and Fig. 5 is a cross section to.
Das Filtergehäuse 1 (Abb. I) ist durch Trennwände2 in drei gegeneinander abgeschlossene B hälter 3, 4, 5 aufgeteilt. Durch einen entsprechen den Mechanismus geführt und dabei sowohl in vertikaler als auch horizontaler Richtung bewegt, tauchen die Filterzellen 6 erst vollständig in den mit Filtergut beschickten Behälter 3 ein. Unter -Über- oder Unterdruck beladen sie sich hier mit den aus dem Filtergut zu entfernenden Feststoffen; ohne dabei ihren Weg zu unterbrechen, werden sie aus dem Becken 3 herausgehoben und in das nächste mit Waschflüssigkeit gefüllte Becken 4 gesenkt. The filter housing 1 (Fig. I) is divided into three against each other by partition walls2 closed B containers 3, 4, 5 divided. Through a match the mechanism guided and moved in both vertical and horizontal direction, diving the filter cells 6 only completely into the container 3 loaded with filter material a. Under overpressure or underpressure, they are loaded here with those from the filter material solids to be removed; without interrupting their path, they will go out lifted out of basin 3 and into the next basin filled with washing liquid 4 lowered.
Hier erfolgt die Waschung des Filterkuchens bei stetiger Fo,rtbewegung ebenfalls unter Uber- oder Unterdruck. Nach dem Durchlaufen durch das Waschmittel werden die Filterzellen mit den anhaftenden Filterkuchen aus der Waschflüssigkeit gehoben. Anschließend wird der Filterkuchen getrocknet, dnnn von der Filterzelle abgestreift oder abgeblasen und aus dem Filtergehäuse entfernt.Here the filter cake is washed with constant forward movement also under overpressure or underpressure. After going through the detergent the filter cells with the adhering filter cake are removed from the washing liquid upscale. The filter cake is then dried, thin from the filter cell stripped or blown off and removed from the filter housing.
Nach erfolgter Entfernung des Filterkuchens von den Filterzellen werden letztere wieder in das Filtergut getaucht, und der ganze oben wiedergegebene Vorgang wiederholt sich so in kontinuierlichem Verlauf. Statt eines Waschbeckens 4 können mehrere hintereinanderliegende Becken vorgesehen sein, so daß der Wascheffekt erheblich verbessert werden kann.After the filter cake has been removed from the filter cells the latter dipped back into the filter material, and the whole process reproduced above repeats itself in a continuous process. Instead of a sink 4 can several basins lying one behind the other can be provided, so that the washing effect is considerable can be improved.
Zur Durchführung dieses grundsätzlichen und bekannten Verfahrens dient die in den Abb.. 2 bis 5 als Ausführungsbeispiel wiedergegebene Vorrichtung, welche vorzugsweise zylindrisch lausgebildet ist. Die Filterzellen 6 sind an Rohren befestigt, welche an einen z. B. von einer Säule getragenen Steuerknopf (Abb. 2) sternförmig zusammenlaufen. To carry out this basic and known method the device shown as an exemplary embodiment in Figs. 2 to 5 is used, which is preferably cylindrical in shape. The filter cells 6 are on pipes attached, which is attached to a z. B. Control button carried by a column (Fig. 2) converge in a star shape.
Vom Steuerkopf aus werden die Rohre und damit die Filterzellen in horizontaler und von den die Rohre tragenden Spindeln in vertikaler Richtung bewegt. Das durch die Filterzellen tretende Filtrat bzw. das Waschmittel werden durch die Rohre, die durch den Steuerkopf nach unten geführt sind, zu den Sammelbecken abgeleitet. Soll das Ausflltrieren unter Überdruck durchgeführt werden, so wird dss ganze Filterzellenaggregat in einem druckfesten Gehäuse (Abb. 3) untergebracht, wobei dieses Ge häuse gleichzeitig durch Anordnung von Zwischenwänden der Aufnahme von Filtergut, Waschflüssigkeit und Filterkuchen dient. Um eine größtmögliche Leistung des Filters bei kleinsten Abmessungen des Filtergehäuses zu erzielen, ist die Oberfläche der Filterzellen durch entsprechende räumliche Gestaltung in an sich bekannter Weise stark vergrößert.From the control head, the pipes and thus the filter cells are in moved horizontally and by the spindles carrying the tubes in the vertical direction. The filtrate or detergent passing through the filter cells is removed by the Pipes, which are led down through the control head, diverted to the collecting basin. If the filtration is to be carried out under overpressure, the entire filter cell assembly becomes housed in a pressure-resistant housing (Fig. 3), this housing at the same time by arranging partitions to accommodate the filter material and washing liquid and filter cake is used. In order to achieve the greatest possible performance of the filter with the smallest To achieve dimensions of the filter housing, is the surface of the filter cells greatly enlarged by appropriate spatial design in a manner known per se.
