Die vorliegende Erfindung betrifft eine Filterstufenvorrichtung zur maschinellen Feststoffseparation aus in Kanälen, Gerinnen oder Leitungen strömenden Flüssigkeiten, welche eine Vielzahl von zu einem feststehenden Rost verbundene Stufenrechenstäbe und eine Vielzahl von zu einem beweglichen Rost verbundene Stufenrechenstäbe aufweist, wobei die Roste innerhalb der strömenden Flüssigkeit ausgehend von einem unter der Oberfläche gelegenen Niveau in Strömungsrichtung geneigt angeordnet und die Stufenrechenstäbe in der der einlaufenden Strömung zugewandten Richtung stufenförmig ausgebildet sind, und bei der der bewegliche Rost mit einer Antriebseinrichtung auf einer Bahn betätigbar ist, die, ausgehend von einer in vertikaler und horizontaler Richtung mit dem feststehenden Rost identischen Null-Lage, eine über die Stufen der zu dem feststehenden Rost verbundenen Stufenrechenstäbe und entgegen der einlaufenden Strömung zugewandten Richtung sich erhebende Hubbewegung bis mindestens zu einer mit der nächsthöheren Stufe des feststehenden Rostes in vertikaler und in horizontaler Richtung identischen Lage erlaubt und die Stufenrechenstäbe des beweglichen Rostes anschließend unterhalb des feststehenden Rostes zurück in die Null-Lage führt, wobei der feststehende Rost zumindest seitlich von Rahmenteilen umgeben ist. The present invention relates to a filter stage device for mechanical solids separation from in Channels, channels or channels flowing liquids, which a variety of to a fixed grate connected step rakes and a variety of one movable grate connected step rakes, with the grates inside the flowing liquid starting from a level below the surface in Flow direction arranged inclined and the step rakes in the direction of the incoming flow Are stepped direction, and in which the movable grate with a drive device on a track is actuated, starting from one in vertical and horizontal direction identical to the fixed grate Zero position, one over the steps of the to the fixed Rust connected step rakes and against the incoming flow rising direction rising Lift movement up to at least one with the next higher one Fixed grate level in vertical and in horizontal direction allowed identical position and the Moving grate subsequent level rulers below the fixed grate back to the zero position leads, the fixed grate at least laterally from Frame parts is surrounded.
Derartige Vorrichtungen sind als Stufenrechen bekannt und dienen innerhalb von Klär- oder Separieranlagen dazu, in Abwässern vorhandene Feststoffe auszutragen.Such devices are known as step rakes and are used within sewage or separation plants to Waste water to discharge existing solids.
Die EP-A-0 098 820 offenbart einen Stufenfilter, bei dem die Antriebseinrichtung oberseitig der Roste vorhanden ist, wobei die Bewegung des beweglichen Rostes über ein Exzenterrad und eine an dieses Exzenterrad angeschlossene, den feststehenden Rost von oben und außen her umgreifende Trageinrichtung übertragen wird.EP-A-0 098 820 discloses a step filter in which the Drive device is provided on the top of the grids, the movement of the movable grate over a Eccentric wheel and one connected to this eccentric wheel, gripping the fixed grate from above and outside Carrier is transferred.
Die üblichen Konstruktionen solcher Vorrichtungen weisen den Nachteil auf, daß jeweils eine relativ große Bauhöhe vorgesehen ist. Die Antriebselemente werden bei einem relativ großen und über mehrere Stufen reichenden Hub solcher Rechen weit oberhalb der Roste angebracht, damit zwischen Antriebselement und bewegten Rosten noch genügend lichte Höhe für den Durchtritt auch größerer Festkörper zur Verfügung steht. Eine solche Ausbildung verursacht jedoch auch eine entsprechende Dimensionierung der Kanalquerschnitte und Einläufe, was wiederum den Aufwand und die Kosten zur Erstellung der Einlaufbauwerke für z.B. Kläranlagen wesentlich erhöht.The usual designs of such devices have the Disadvantage that a relatively large overall height is provided. The drive elements are at one relatively large and multi-stage stroke such rakes attached far above the gratings, so between drive element and moving grates still sufficient Clear height for the passage of larger solid bodies Available. However, such training causes a corresponding dimensioning of the channel cross sections and enemas, which in turn takes the effort and the Costs for the construction of the intake structures for e.g. Sewage treatment plants increased significantly.
Die DE-A-40 01 859 offenbart einen Siebrechen zur Entnahme von festen Bestandteilen aus strömenden Flüssigkeiten, bei dem unterhalb der Gitterstäbe ein Kurbeltrieb angeordnet ist, der die Bewegung der beweglichen Gitterstäbe steuert. Die gewählte Hebelanordnung stützt sich hierbei auf Gleitkufen ab, die in Führungsprofilen des Traggerüstes gelagert sind. DE-A-40 01 859 discloses a sieve screen for removal of solid components from flowing liquids, at a crank mechanism is arranged below the bars which controls the movement of the movable bars. The selected lever arrangement is based on this Skids from the guide profiles of the supporting structure are stored.
Die WO-A-94/24373 offenbart einen Filterstufenrechen, bei dem der bewegliche Rost oberseitig exzentrisch an ein Rad angeschlossen ist, wobei an dieses Rad ebenfalls exzentrisch eine lange dünne Stange angeschlossen ist, die wiederum am anderen Endbereich über Ketten an dem Rahmen gelagert ist und dadurch eine Art elliptische Drehbewegung auf den beweglichen Rost in diesem Bereich überträgt. Da im Bereich des oberen exzentrischen Anschlusses des beweglichen Rostes eine im wesentlichen kreisförmige Bewegung der einzelnen Stufen abläuft und im unteren Bereich eine elliptische Bewegung abläuft, sind über den Verlauf der Stufenrechenstäbe in Längsrichtung unterschiedliche Profilausbildungen erforderlich, um einen zuverlässigen Austrag zu gewährleisten. Des weiteren ist die Kettenlagerung der Schubstange im unteren Bereich hinsichtlich dauerhaft zuverlässiger Funktion nicht optimal.WO-A-94/24373 discloses a filter stage rake in which the movable grate eccentrically on the top of a wheel is connected, with this wheel also eccentric a long thin rod is connected, which in turn on other end area is mounted on chains on the frame and thereby a kind of elliptical rotary movement on the moving rust in this area. Because in the area of the upper eccentric connection of the movable grate an essentially circular movement of the individual Steps expires and in the lower area an elliptical Movement expires are over the course of the step rulers different profiles in the longitudinal direction required to have a reliable discharge guarantee. Furthermore, the chain bearing is the Push rod in the lower area with regard to permanent reliable function is not optimal.
Der Erfindung liegt, ausgehend von dem genannten Stand der Technik, die Aufgabe bzw. das technische Problem zugrunde, einen Stufenrechen vorzuschlagen, bei dem der für einen sicheren Betrieb nötige Raumbedarf minimiert ist und gleichzeitig bei beliebig steiler Neigung in Strömungsrichtung der Durchtritt auch größerer Feststoffkörper ohne Probleme ermöglicht wird. Die Konstruktion soll dabei einfach, robust und wartungsarm ausgebildet sein.The invention is based on the state of the art Technology, the task or the technical problem, to propose a step rake in which the for one safe operation necessary space is minimized and at the same time with any steep inclination in the flow direction the passage of even larger solid bodies without Problems. The construction is supposed to simple, robust and low maintenance.
Die erfindungsgemäße Filterstufenvorrichtung ist durch die
Merkmale des unabhängigen Anspruchs 1 gegeben. Vorteilhafte
Ausgestaltungen und Weiterbildungen werden durch die
abhängigen Ansprüche erfaßt. The filter stage device according to the invention is by the
Features of
Die erfindungsgemäße Vorrichtung zur maschinellen Feststoffseparation aus Flüssigkeiten zeichnet sich demgemäß dadurch aus, daß alle Antriebselemente des beweglichen Rostes im wesentlichen in der durch den feststehenden Rost und den beweglichen Rost in der Null-Lage gebildeten gemeinsamen Ebene angeordnet sind.The device according to the invention for mechanical solid separation Accordingly, liquids are characterized by this from that all drive elements of the movable grate in essentially in the by the fixed grate and the movable grate formed in the common zero position Level are arranged.
Durch eine solche Ausbildung der Vorrichtung ergibt sich ein modulartiger Aufbau, bei der die gesamte Vorrichtung einschließlich des Antriebes innerhalb von lediglich durch einfachste Seitenbauwerke oder seitliche Haltekonstruktionen begrenzten Kanalquerschnitten als sofort funktionsfertige Bauteile eingesetzt und betrieben werden kann, ohne daß aufwendige Bauten oder Gerinneführungen, Maschinenkästen oder -häuser, Steuerungen oder Getriebeeinbauten oder Einrichtungen für Zubehörteile erstellt werden müssen.Such a design of the device results in a modular structure in which the entire device including the drive within just by simplest side structures or side support structures limited channel cross sections as ready to use Components can be used and operated without elaborate structures or channels, machine boxes or houses, controls or gear units or Equipment for accessories must be created.
Der modulartige Aufbau erlaubt gleichermaßen einen leichten Einbau in schon bestehende Systeme, etwa bei einem durch Verschleiß der Altanlage notwendigen Austausch der Recheneinrichtungen, und eignet sich somit hervorragend zur Anpassung von Gerinnereinigungen auf etwa im Lauf der letzten Jahrzehnte veränderten Abwasserfraktionen, aber auch auf neue gesetzliche Vorschriften im Hinblick auf die weitere Entsorgung der behandelten Wässer.The modular structure also allows easy Installation in existing systems, for example with one Wear of the old system necessary replacement of the Computing devices, and is therefore ideal for Adjustment of clot cleaning to approximately in the course of wastewater fractions have changed in recent decades, too to new legal regulations with regard to the further disposal of the treated water.
Durch die Anordnung der Antriebselemente des beweglichen Rostes im wesentlichen in der durch den feststehenden Rost und den beweglichen Rost in der Null-Lage gebildeten gemeinsamen Ebene sind darüberhinaus beliebige Winkellagen der Vorrichtung zu realisieren, so daß ein auf die zu erwartende Größe der Feststoff-Fraktion mehr oder weniger steiler Aushub vorgesehen werden kann. Da alle Antriebselemente innerhalb des Moduls untergebracht sind, bleibt trotz einer gravierenden Reduzierung von Bauraum und Bauaufwand genügend Durchtrittsraum als lichte Höhe oberhalb der Rechenstäbe.Due to the arrangement of the drive elements of the movable Rust essentially in the by the fixed grate and the movable grate formed in the zero position common plane are also any angular positions to implement the device so that one towards the expected size of the solid fraction more or less steep excavation can be provided. Because all drive elements are housed within the module remains despite a serious reduction in installation space and Construction effort sufficient passage space as clear height above the rulers.
Vorteilhafterweise beinhalten die Antriebselemente angetriebene und in einem Rahmen des feststehenden Rostes gelagerte Räder, wobei der bewegliche Rost exzentrisch und radial zur Räderachse an den Rädern angelenkt ist.The drive elements advantageously include driven and in a frame of the fixed grate mounted wheels, the movable grate being eccentric and is articulated radially to the wheel axis on the wheels.
Eine solche Ausbildung erlaubt eine Minimierung sowie die Kapselung und Integration der Antriebselemente innerhalb von tragenden, insbesondere hohlen Rahmenteilen, so daß solche Antriebselemente auch unterhalb des Wasserspiegels angeordnet sein können und lediglich leicht abzudichtende Drehdurchführungen vorgesehen werden müssen.Such training allows minimization as well as Encapsulation and integration of the drive elements within load-bearing, in particular hollow frame parts, so that such Drive elements also below the water level can be arranged and only easy to seal Rotary unions must be provided.
Eine nahezu wartungsfreie Konstruktion erreicht man dadurch, daß die Antriebselemente angetriebene und in einem Rahmen des feststehenden Rostes gelagerte seitliche Wangen beinhalten, wobei der bewegliche Rost exzentrisch an einem von der Lagerung beabstandeten Punkt an den Wangen angelenkt ist. Ein solcher Antrieb läßt sich auf einfachste Weise herstellen und benötigt zur Überwachung lediglich eine Sichtkontrolle. Reparatur- und/oder Austauscharbeiten können in einfacher Art und Weise durchgeführt werden.An almost maintenance-free construction can be achieved that the drive elements are driven and in a frame side cheeks of the fixed grate include, the movable grate eccentrically on a articulated point on the cheeks spaced from the bearing is. Such a drive can be done in the simplest way produce and only needs one for monitoring Visual inspection. Repair and / or exchange work can be carried out in a simple manner.
In einer weiteren vorteilhaften Ausbildung erfolgt der Antrieb über auf die Räder/Wange/n wirkende Kettentriebe oder Kardanwellen. Eine solche Konstruktion unterstützt die kompakte Bauweise und ermöglicht das sichere Übertragen großer Kräfte, wodurch auch sperriger und schwerer Austrag problemlos zu handhaben ist.In a further advantageous embodiment, the Drive via chain drives acting on the wheels / cheek / s or cardan shafts. Such a construction supports the compact design and enables safe transfer large forces, which also makes bulky and heavy discharge is easy to handle.
Eine weitere und im Hinblick auf eine kompakte modulartige Bauweise wirksame und in der Vorrichtung vorteilhafte Konstruktionsmaßnahme besteht darin, daß die Bewegungsbahn von der Null-Lage zur höheren Stufe und zurück in ihren äußersten Stellungen die durch den feststehenden Rost aufgespannte Ebene um nicht mehr als die doppelte Stufenhöhe verläßt. Im Zusammenwirken mit den bereits genannten Kettentrieben oder Kardanwellen können die notwendigen Bewegungsglieder und -führungen dann relativ klein bauend ausgelegt werden.Another and in terms of a compact modular Effective construction and advantageous in the device Construction measure is that the trajectory from the zero position to the higher level and back to theirs extreme positions by the fixed grate spanned level by no more than twice the step height leaves. In cooperation with the already mentioned Chain drives or cardan shafts can do the necessary Movement elements and guides then relatively small be interpreted.
