Description

Rückspülbares Siebfilter mit senkrecht in einem Gehäuse angeordneten Siebtrommeln aus Drahtgewebe für Flüssigkeiten oder Gase Die Erfindung betrifft Siebfilter mit senkrecht angeordneten Siebtrommeln aus Drahtgewebe für Flüssigkeiten oder Gase. Bei den bisher bekannten Siebfiltern dieser Art müssen die Siebe zur Reinigung von den in ihnen abgeschiedenen und sie allmählich verstopfenden Fremdkörpern von Zeit zu Zeit ausgebaut, die Filtervorrichtungen also stillgesetzt werden. Die dadurch entstehenden längeren Betriebsunterbrechungen sind störend und kostspielig.Backwashable screen filter with arranged vertically in a housing Wire mesh screen drums for liquids or gases The invention relates to Sieve filter with vertically arranged sieve drums made of wire mesh for liquids or gases. In the previously known sieve filters of this type, the sieves have to Cleansing of the foreign bodies deposited in them and gradually clogging them expanded from time to time, so the filter devices are shut down. the the resulting longer operational interruptions are disruptive and costly.

Bei Filtervorrichtungen anderer Gattung, nämlich Drehfiltern mit waagerecht angeordneter und mit einem Filtertuch bespannter Trommel ist es bekannt, die Reinigung dadurch zu erleichtern und zu verbessern, daß das Filtertuch örtlich ausgebeult und mit Schlagwerkzeugen bearbeitet wird. Die auf die jeweils ausgebeulte Zone des Filtertuches ausgeübten Schläge vermögen die beabsichtigte Wirkung nur ungenügend herbeizuführen, da Filtertücher schwingungstechnisch dämpfend wirken und die Schwebestoffe sich aus den sie festhaltenden Härchen der Filtertücher durch Schläge nur zu einem geringen Teil ausklopfen lassen. Die Filtertücher müssen daher doch von Zeit zu Zeit zur gründlichen Reinigung ausgebaut werden. In the case of filter devices of another type, namely rotary filters with horizontally arranged drum covered with a filter cloth, it is known to facilitate and improve cleaning by the fact that the filter cloth locally bulged and worked with striking tools. The one on the bulged one Impacts exerted in the zone of the filter cloth can only have the intended effect insufficient, as filter cloths have a dampening effect on vibrations and the suspended matter emerges from the tiny hairs on the filter cloths that hold them in place Beat out only a small part of the beats. The filter cloths must therefore but should be removed from time to time for thorough cleaning.

Bei Filtervorrichtungen mit senkrecht angeordneter Siebtrommel od. dgl. und tangentialem Zufluß ist es bekannt, zwecks Wegfalls von Rührwerken oder Schabern zur Abscheidung der Feststoffe den tangentialen Rohflüssigkeitseinlaß unterhalb des Filterkörpers so einmünden zu lassen, daß ein Flüssigkeitswirbel gebildet wird. Beim peri- odischen Ablassen des Schlammes durch ein Ventil ist hierbei ein Rückspülen des Filtrats vorgesehen. For filter devices with a vertically arranged drum screen or. Like. And tangential inflow, it is known for the purpose of eliminating agitators or Scraper the tangential raw liquid inlet below to separate the solids to allow the filter body open so that a fluid vortex is formed. In the peri- odic discharge of the sludge is through a valve backwashing of the filtrate is provided here.

Eine wirksame Reinigung des Filters ist jedoch in vielen Fällen durch Erzeugung eines Flüssigkeitswirbels und durch Rückspülen des Filtrats nicht möglich. Schließlich ist es bekannt, bei Flüssigkeitsfiltern das Filterelement als Teil eines Kolbens auszubilden, durch dessen plötzliche Bewegung die Strömungsrichtung der Flüssigkeit durch den Filter zeitweilig stoßweise umgekehrt wird. Die Einströmöffnungen für die Rohflüssigkeit sind dabei gegenüber der Filterfläche so angeordnet, daß die zuströmende Rohflüssigkeit während des Rückspülhubes des Kolbens längs dessen Filterfläche geführt wird, um die Filterrückstände fortzuspülen. Diese bekannten Filtervorrichtungen sind durch die Ausbildung eines Teils des Filterelements als beweglicher Kolben und durch die von der Kolbenbewegung abgeleitete Umkehrung der Strömungsrichtung der Flüssigkeit durch das Filter verhältnismäßig kompliziert. Außerdem ist erfahrungsgemäß allein durch Umkehrung der Strömungsrichtung der Flüssigkeit, auch wenn sie stoßweise erfolgt, eine wirksame Reinigung des Filters nicht erreichbar.However, in many cases the filter is effectively cleaned Creation of a fluid vortex and not possible by backwashing the filtrate. Finally, it is known in the case of liquid filters, the filter element as part of a Form piston, through the sudden movement of the flow direction of the Liquid is temporarily reversed intermittently through the filter. The inflow openings for the raw liquid are arranged opposite the filter surface so that the incoming raw liquid during the backwash stroke of the piston along it Filter surface is guided to flush away the filter residue. These well-known Filter devices are by forming part of the filter element as movable piston and by the reversal of the piston movement derived from the The direction of flow of the liquid through the filter is relatively complicated. In addition, experience has shown that only by reversing the direction of flow of the liquid, even if it takes place intermittently, an effective cleaning of the filter cannot be achieved.

Durch die Erfindung wird bei Siebfiltern mit einer oder mehreren senkrecht angeordneten Siebtrommeln aus Drahtgewebe eine besonders gründliche Reinigung der Filtersiebe in ihrem Betriebszustand, also ohne sie auszubauen, dadurch erzielt, daß in Kombination ein Antrieb zur Erschütterung der nachgiebig gelagerten Siebtrommel oder -trommeln als Ganzes durch stoßende und schwingende Bewegung und eine Einrichtung zum Spülen der Siebtrommel oder -trommeln mit Flüssigkeit, Gas oder Luft im Gegenstrom vorgesehen sind. Die Siebtrommel oder -trommeln können auch drehbar ausgebildet sein und sich zur Reinigung an einer ortsfest angeordneten Düsenreihe zum Spülen im Gegenstrom vorbeibewegen. The invention is in screen filters with one or more vertically arranged drums made of wire mesh a particularly thorough cleaning the filter sieves in their operating state, i.e. without dismantling them, achieved by that in combination a drive to vibrate the resiliently mounted sieve drum or drums as a whole by thrusting and vibrating motion and a device for rinsing the sieve drum or drums with liquid, gas or air in countercurrent are provided. The sieve drum or drums can also be designed to be rotatable be and for cleaning at a stationary row of nozzles for rinsing move past in countercurrent.

Bei Anordnung von zwei ineinandersteckenden Siebtrommeln ist zweckmäßig die äußere Siebtrommel drehbar und bewegt sich an einer ortsfesten Düsenreihe zum Spülen im Gegenstrom vorbei, während die innere Siebtrommel undrehbar, jedoch gegebenenfalls hebbar angeordnet ist. Bei dieser Ausführung von Siebfiltern ist zweckmäßig im Innern der äußeren Siebtrommel eine sich mit ihr drehende Düsenreihe zum Spülen der inneren sich nicht drehenden Trommel vorgesehen.When arranging two nested sieve drums it is advisable the outer drum can be rotated and moves to a fixed row of nozzles Rinse in countercurrent while the inner sieve drum cannot be rotated, but if necessary is arranged liftably. In this design of screen filters is useful inside the outer sieve drum has a row of nozzles rotating with it for rinsing the inner ones non-rotating drum provided.

Ein Ausführungsbeispiel des neuen Siebfilters ist in der Zeichnung schematisch dargestellt. Es zeigt: Fig. I einen Filter mit zwei Siebtrommeln im Betriebszustand im Schnitt, Fig. 2 den gleichen Filter in Reinigungsstellung. An embodiment of the new screen filter is shown in the drawing shown schematically. It shows: FIG. I a filter with two sieve drums in the Operating state in section, FIG. 2 shows the same filter in the cleaning position.

Die dargestellte Filtervorrichtung weist zwei ineinandersteckende Siebtrommeln b1 und b2 auf. Die äußere Siebtrommel b2 ist drehbar, die innere Siebtrommel bl undrehbar, jedoch hebbar ausgebildet. The filter device shown has two nested ends Screen drums b1 and b2 on. The outer drum screen b2 is rotatable, the inner drum screen bl non-rotatable, but designed to be liftable.

Die Vorrichtung zum Anheben der Siebtrommel b1 ist durch ein Zugorgan schematisch angedeutet.The device for lifting the sieve drum b1 is through a pulling element indicated schematically.

Die Siebtrommeln können, ohne sie auszubauen, von anhaftenden Feststoffen gründlich gereinigt werden. Zu diesem Zweck ist im Innern der Siebtrommeln, eine Düsenreihe h1 befestigt, durch welche in Reinigungsstellung der Filtervorrichtung (Fig. 2) nach Absperrung der normalen Ein-und Austrittsöffnung c, d Flüssigkeit oder Gas (z. B. Luft) durch besondere Zuleitungen unter Druck im Gegenstrom auf die stillstehende Siebtrommel b1 wirkt. Die abgelösten Fremdkörper gelangen durch ein am unteren Ende der Siebtrommel b1 befindliches Ventil K, welches sich beim Anheben der Siebtrommel b1 zweckmäßig zwangläufig öffnet, in das Sammelrohr g. Die durch den bei l angedeuteten Antrieb sich drehende Siebtrommel b2 bewegt sich an einer ortsfesten Düsenreihe h2 vorbei, durch welche die äußere Siebtrommel von anhåftenden Fremdkörpern gereinigt wird, die ebenfalls in das Sammelrohr g gelangen und durch die Austrittsöffnung e entfernt werden.The screening drums can remove adhering solids without dismantling them be thoroughly cleaned. For this purpose there is one inside the sieve drum Row of nozzles h1 attached, through which in the cleaning position of the filter device (Fig. 2) after blocking the normal inlet and outlet openings c, d liquid or gas (e.g. air) through special feed lines under pressure in countercurrent the stationary sieve drum b1 acts. The detached foreign bodies get through a valve K located at the lower end of the sieve drum b1, which is located at Raising the sieve drum b1 expediently inevitably opens into the collecting tube g. the by the rotating sieve drum b2 indicated at l starts moving a stationary row of nozzles h2, through which the outer sieve drum of adhering Foreign bodies is cleaned, which also get into the collecting pipe g and through the outlet opening e can be removed.

Das Ablösen der Fremdkörper aus den Maschen der Siebe b1 und b2 durch Spülen im Gegenstrom wird dadurch unterstützt, daß die Siebtrommeln gleichzeitig durch einen bei t schematisch angedeuteten Antrieb als Ganzes in stoßende bzw. schwingende Bewegung versetzt werden.The detachment of the foreign bodies from the meshes of the sieves b1 and b2 through Countercurrent rinsing is supported by the fact that the sieve drums are simultaneously by a drive schematically indicated at t as a whole into pushing or oscillating Movement can be displaced.
