Description

Die Erfindung betrifft ein Becken, insbesondere ein Regen- oder Klärbecken gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a basin, in particular a rain or clarifier according to the preamble of patent claim 1.

Aus der Patentschrift FR-A-2449654 ist eine schwimmende Tauchwand bekannt, welche in einem Regen- oder Klärbecken angeordnet ist zur Rückhaltung von im Oberflächenbereich des Wassers schwimmenden Verunreinigungen bei Hochwasser. Die über die Breite des Beckens sich erstreckende Tauchwand ist verschwenkbar im Becken montiert derart, dass sie sich bei tiefem Wasserstand in ihrer unteren Lage befindet und mit ihrer Unterkante an der ablaufseitigen Stirnwand des Beckens anliegt, wie aus der Fig. 3 bis 6 der Zeichnungen hervorgeht.From the patent specification FR-A-2449654 a floating baffle is known, which is arranged in a rain or clarifier for the retention of contaminants floating in the surface area of the water during floods. The baffle extending over the width of the basin is pivotally mounted in the basin in such a way that it is in its lower position when the water level is low and its lower edge rests on the end wall of the basin at the outlet, as can be seen from FIGS. 3 to 6 of the drawings .

Häufig wird für solche Becken auch eine Spülkippe verwendet, die dazu bestimmt ist, die auf der Sohle des Beckens sich bildenden Ablagerungen periodisch bei leerem Becken zu entfernen. Eine solche Spülkippe geht aus der Patentschrift FR-A-2449487 hervor. Fig. 1 und 2 zeigen diese bekannte Ausbildung, wobei zwei mögliche Lagen der Tauchwand eingezeichnet sind. Die zweite Lage der Tauchwand, bei welcher die Unterkante die Sohle berührt, wird hauptsächlich dann vorgesehen, wenn infolge von Hindernissen wie Ueberlaufkanal, Laufsteg, statische Säule usw. ein anderer Einbau ungeeignet ist.Often a sink is also used for such basins, which is intended to periodically remove the deposits that form on the bottom of the basin when the basin is empty. Such a rinsing tip is evident from the patent FR-A-2449487. 1 and 2 show this known design, two possible positions of the baffle are shown. The second position of the baffle, in which the lower edge touches the sole, is mainly provided when another installation is unsuitable due to obstacles such as overflow channel, catwalk, static column, etc.

Die bekannten Becken mit einer Spülkippe und einer Tauchwand in obiger Anordnung sind in verschiedener Hinsicht nachteilig. Die Tauchwand wird vom Spülwasser mechanische beansprucht. Wenn der Wasserschwall der Spülkippe ins Becken strömt, wird die Tauchwand weggeschlagen, nachher fällt sie wieder zurück und schlägt an der Wand oder der Sohle auf, was zu Beschädigungen führen kann. In anderen Fällen bildet die Tauchwand ein Hindernis für die Strömung, so dass u. U. das Spülwasser der Spülkippe die Tauchwand gar nicht anzuheben vermag, was dazu führt, dass die Sohle des Beckens hinter der Tauchwand unvollständig gereinigt wird.The known basins with a flushing tip and a baffle in the above arrangement are disadvantageous in various respects. The diving wall is mechanically stressed by the rinse water. If the surge of water flows into the basin, the diving wall is knocked away, afterwards it falls back and hits the wall or the sole, which can lead to damage. In other cases, the baffle is an obstacle to the flow, so that u. U. the rinse water of the rinsing tip is unable to lift the baffle at all, which means that the bottom of the pool behind the baffle is not completely cleaned.

Es ist nun Aufgabe der vorliegenden Erfindung, ein Becken der gattungsgemässen Art zu schaffen, bei welcher die erwähnten Nachteile vermieden sind. Die Lösung dieser Aufgabe erfolgt erfindungsgemäss durch die in der Kennzeichnung des Patentanspruches 1 definierten Merkmale.It is an object of the present invention to provide a basin of the generic type in which the disadvantages mentioned are avoided. This object is achieved according to the invention by the features defined in the characterizing part of patent claim 1.

Nachstehend werden anhand der Fig. 3-6 der Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert. Die beiden Fig. 1 und 2 stellen die in der Beschreibungseinleitung erwähnten bekannten Ausführungsformen dar. Es zeigen :

  • Figur 1 einen Längsschnitt durch ein gefülltes Klärbecken mit einer darin angeordneten Tauchwand,
  • Figur 2 einen Längsschnitt durch ein leeres Klärbecken mit einer Spülkippe und zwei möglichen Anordnungen der Tauchwand,
  • Figur 3 einen Längsschnitt durch ein Klärbecken mit einer ersten Ausführungsform der Hebevorrichtung,
  • Figur 4 eine Draufsicht auf das Becken gemäss Fig. 3,
  • Figur 5 einen Längsschnitt durch ein Klärbecken mit einer zweiten Ausführungsform der Hebevorrichtung, und
  • Figur 6 eine Draufsicht auf das Becken gemäss Fig. 5.
Exemplary embodiments of the invention are explained in more detail below with reference to FIGS. 3-6 of the drawings. The two FIGS. 1 and 2 represent the known embodiments mentioned in the introduction to the description.
  • 1 shows a longitudinal section through a filled clarifier with a baffle arranged therein,
  • FIG. 2 shows a longitudinal section through an empty clarifier with a flushing tip and two possible arrangements of the baffle,
  • FIG. 3 shows a longitudinal section through a clarifier with a first embodiment of the lifting device,
  • FIG. 4 shows a top view of the basin according to FIG. 3,
  • 5 shows a longitudinal section through a clarifier with a second embodiment of the lifting device, and
  • FIG. 6 shows a top view of the basin according to FIG. 5.

Bei dem in der Fig. 1 dargestellten Klärbecken 1 ist eine sich über die Breite des Beckens erstreckende Tauchwand 2 verschwenkbar an der ablaufseitigen Stirnwand des Beckens montiert. Die Tauchwand 2 ist mit einem Hohlkörper 3 versehen, damit sie im Wasser schwimmen kann.In the clarification tank 1 shown in FIG. 1, a baffle 2 extending over the width of the tank is pivotally mounted on the outlet-side end wall of the tank. The baffle 2 is provided with a hollow body 3 so that it can swim in the water.

Das während Trockenperioden zuströmende Schmutzwasser fliesst über eine nicht näher dargestellte Eingangsleitung in das Klärbecken 1 und gelangt über eine ebenfalls nicht dargestellte Ausgangsleitung, welche sich im Bereich der Sohle 4 befindet, in eine Kläranlage. Eine zusätzliche Meteorwassermenge bei schwachem Regen vermag durch die Ausgangsleitung noch geschluckt zu werden. Bei Hochwasser, z. B. nach heftigen Niederschlägen, genügt die Ausgangsleitung aber nicht mehr, um die zuströmende Wassermenge abfliessen zu lassen.The wastewater flowing in during dry periods flows into the clarification tank 1 via an inlet line, not shown, and arrives at a sewage treatment plant via an outlet line, also not shown, which is located in the area of the base 4. An additional amount of meteor water during light rain can still be swallowed by the outlet pipe. In the event of floods, e.g. B. after heavy rainfall, but the output line is no longer sufficient to drain the inflowing amount of water.

Der Wasserspiegel steigt an. Die durch das Regenwasser von Strassen, Plätzen, usw. mitgeschwemmten Verunreinigungen 5 und Gegenstände, wie z. B. Holz, Laub, Papier, Tierkadaver und Oel, werden ins Klärbecken transportiert und schwimmen auf dem Wasserspiegel obenauf. Die Verunreinigungen stauen sich hinter der Tauchwand 2 an.The water level rises. The contaminated with the rain water from streets, squares, etc. 5 and objects such. B. wood, leaves, paper, animal carcasses and oil are transported to the clarifier and float on the water surface on top. The impurities accumulate behind the baffle 2.

Bei weiter steigendem Wasser über die Höhe H1 wird die Tauchwand 2 infolge des Auftriebes angehoben, wobei sie sich um den Drehpunkt 6 verschwenkt, bis sie etwa senkrecht steht (in Fig. 1 gestrichelt eingezeichnet). Das Wasserniveau H2 entspricht der Höhe der Ueberlaufkante der oberen Ausflussöffnung 7 des Beckens 1. Beim Erreichen dieser Höhe kann das Wasser ablaufen, wobei aber die Verunreinigungen durch die Tauchwand zurückgehalten werden.When the water rises further above the height H 1 , the baffle 2 is raised as a result of the buoyancy, pivoting about the pivot point 6 until it is approximately vertical (shown in dashed lines in FIG. 1). The water level H 2 corresponds to the height of the overflow edge of the upper outlet opening 7 of the basin 1. When this height is reached, the water can run off, but the impurities are retained by the baffle.

Die zweite Ausführungsform der Tauchwand 8 gemäss der Fig. 2 funktioniert analog wie die Tauchwand 2. Ihre Unterkante liegt bei leerem Becken 1 auf der Sohle 4 auf. Durch die Tauchwand 8 wird das Becken in einen vorderen und einen hinteren Abschnitt unterteilt, wobei sich im zuletzt genannten Abschnitt die Verunreinigungen sammeln. Die Tauchwand 8 wird hauptsächlich dann verwendet, wenn Einbauten 9 im Becken vorhanden sind.The second embodiment of the baffle 8 according to FIG. 2 functions analogously to the baffle 2. Its lower edge lies on the sole 4 when the pool 1 is empty. The basin is divided into a front and a rear section by the baffle 8, the contaminants collecting in the last-mentioned section. The baffle 8 is mainly used when there are internals 9 in the pool.

Beim Becken gemäss der Fig. 2 ist eine an sich bekannte Spülkippe 10 vorgesehen. Sie dient zur periodischen Entfernung von Ablagerungen, die sich auf der Sohle 4 bilden. Die Spülkippe 10 ist oberhalb der Sohle 4 angeordnet und erstreckt sich in Querrichtung des Beckens 1. Sie ist um ihre Achse 11 bis etwa 120° verschwenkbar, wobei der Schwerpunkt der leeren oder teilweise gefüllten Kippe nicht mit dem Schwerpunkt der vollen Kippe übereinstimmt. Durch entsprechende Anordnung der Achse 11 zwischen diesen beiden Schwerpunkten wird bewirkt, dass das einfliessende Wasser die im Leerzustand horizontale Spülkippe durch die obere Oeffnung füllt. Während des Füllvorganges verschiebt sich der Schwerpunkt, bis bei mindestens annähernd voller Kippe ein Uebergewicht entsteht, wodurch die Kippe um ca. 120° verschwenkt wird.In the basin according to FIG. 2, a flushing tip 10 known per se is provided. It serves for the periodic removal of deposits that form on the sole 4. The flushing tip 10 is arranged above the sole 4 and extends in the transverse direction of the pelvis 1. It can be pivoted about its axis 11 up to approximately 120 °, the center of gravity of the empty or partially filled dump not matching the center of gravity of the full dump. Appropriate arrangement of the axis 11 between these two focal points has the effect that the inflowing water fills the horizontal flushing tip through the upper opening when empty. During the filling process, the center of gravity shifts until an overweight arises when the tip is at least approximately full, whereby the tip is pivoted by approximately 120 °.

Dies bewirkt, dass sich ein starker Wasserschwall gegen die Beckenwand ergiesst. Das Wasser strömt der Wand entlang nach unten über den abgerundeten Uebergang zwischen Beckenwand und Sohle und dann mit grosser Geschwindigkeit entlang der Sohle, um so den anhaftenden Schmutz zu entfernen und in einen Sumpfkanal zu befördern. Die entleerte Spülkippe schwenkt automatisch wieder in ihre horizontale Lage zurück und der Vorgang wiederholt sich von neuem.This causes a strong surge of water to pour against the pool wall. The water flows down the wall over the rounded transition between the pool wall and the floor and then at high speed along the floor to remove the adhering dirt and convey it into a sump channel. The emptied dump tip automatically swings back into its horizontal position and the process is repeated again.

Um nun zu verhindern, dass dieser Wasserschwall die Tauchwand 8 beschädigt, ist gemäss den Fig. 3-6 eine Hebevorrichtung vorgesehen, welche die Tauchwand 8 anhebt, bevor ein Spülvorgang eingeleitet wird. Nach dem Spülvorgang wird die Tauchwand 8 automatisch wieder gesenkt.In order to prevent this water surge from damaging the baffle 8, a lifting device is provided according to FIGS. 3-6, which lifts the baffle 8 before a rinsing process is initiated. After the flushing process, the baffle 8 is automatically lowered again.

Bei der Ausführungsform nach den Fig. 5 und 6 besitzt die Wasserzuführungsleitung 12 für die Spülkippe 10 einen Abzweiger 13, der zu einem Differential-Wasserbehälter 14 führt, der im oberen Abschnitt des Beckens 1 angeordnet ist. Der Behälter 14 ist in nicht näher dargestellter Weise zwischen einer oberen und einer unteren Endstellung an der Beckenwandung höhenverschiebbar gelagert.In the embodiment according to FIGS. 5 and 6, the water supply line 12 for the flushing tip 10 has a tap 13 which leads to a differential water tank 14 which is arranged in the upper section of the basin 1. The container 14 is mounted in a manner not shown in detail between an upper and a lower end position on the pool wall.

Zwei Seilzüge 15 sind am Behälter 14 befestigt und führen über obere, ortsfeste Rollen 16 zur Tauchwand 8, wo sie an beiden Seiten des Hohlkörpers 3 fixiert sind. Beim Zuführen von Wasser zur Spülkippe 10 gelangt ein Teil dieses Wassers über den Abzweiger 13 in den Behälter 14. Ein im Abzweiger 13 angeordnetes Zuflussventil 17 und ein im Behälterboden angeordnetes Abflussventil 18 werden gegenseitig so einreguliert, dass der Behälter rascher gefüllt wird als die Spülkippe. Bevor die Spülkippe 10 kippt, hat der Behälter 14 genügend Wassergewicht, um die Tauchwand 8 über die Seilzüge 15 anzuheben. Stellt der Zufluss 12 zur Spülkippe ab, entleert sich der Behälter 14 langsam durch das Ventil 18 und lässt die Tauchwand langsam absinken.Two cables 15 are attached to the container 14 and lead via upper, fixed rollers 16 to the baffle 8, where they are fixed on both sides of the hollow body 3. When water is supplied to the rinsing tip 10, part of this water reaches the container 14 via the branch 13. An inflow valve 17 arranged in the branch 13 and an outlet valve 18 arranged in the bottom of the container are mutually regulated in such a way that the container is filled more quickly than the rinsing tip. Before the flushing tip 10 tilts, the container 14 has enough water weight to raise the baffle 8 via the cables 15. If the inflow 12 to the flushing dump stops, the container 14 slowly empties through the valve 18 and lets the baffle wall slowly lower.

Der Wasserschwall kann somit die Sohle 4 reinigen, ohne die Tauchwand 8 zu beschädigen und ohne von dieser gestört zu werden. Nach dem Spülvorgang senkt sich die Tauchwand 8 automatisch wieder ab, da durch das Ventil 18 das Wasser aus dem Behälter entweichen kann und kein Wasser aus der Leitung 13 zufliesst. Oben am Behälter ist noch ein Ueberlauf 19 vorgesehen. Daher kann der Zufluss durch das Ventil 17 soweit geöffnet werden, dass mit Sicherheit immer mehr Wasser zufliesst als durch das Ventil 18 abfliesst, das überschüssige Wasser benützt den Ueberlauf 19. Es wäre auch möglich, das Abflussventil wegzulassen und die Abflussöffnung entsprechend klein zu wählen, damit weniger Wasser abfliesst als oben zufliesst. Die Regulierung der Differenzmenge könnte dann allein durch das Zuflussventil 17 erfolgen. Mit dem Ventil 18 kann die Entleerungszeit des Behälters 14 zwecks langsamem Absenken der Tauchwand ohne aufschlagen reguliert werden.The surge of water can thus clean the sole 4 without damaging the baffle 8 and without being disturbed by it. After the flushing process, the baffle 8 automatically lowers again, since the valve 18 allows the water to escape from the container and no water flows in from the line 13. An overflow 19 is also provided at the top of the container. Therefore, the inflow through valve 17 can be opened to such an extent that surely more and more water flows in than flows out through valve 18, the excess water uses the overflow 19. It would also be possible to omit the drain valve and to select the drain opening accordingly small, so that less water flows off than flows in above. The regulation of the difference quantity could then take place solely through the inflow valve 17. With the valve 18, the emptying time of the container 14 can be regulated without opening for the purpose of slowly lowering the baffle.

Bei der Ausführungsform gemäss den Fig. 3 und 4 sind zwei Behälter 14 vorgesehen, die beidseitig am Beckenrand befestigt sind. Jeder Behälter ist mit einem Seilzug 15 versehen, der über separate Rollen 16 mit der Tauchwand 8 verbunden ist. Entsprechend sind auch zwei Abzweiger 13 vorhanden, die vom Hauptstrang 12 wegführen. Im übrigen ist die Funktionsweise dieser Hebevorrichtung gleich wie diejenige der ersten Ausführungsform.In the embodiment according to FIGS. 3 and 4, two containers 14 are provided, which are attached to the pool edge on both sides. Each container is provided with a cable 15, which is connected to the baffle 8 via separate rollers 16. Correspondingly, there are also two taps 13 which lead away from the main line 12. Otherwise, the operation of this lifting device is the same as that of the first embodiment.

Es wäre auch möglich, in nicht näher dargestellter Weise den oder die Behälter 14 direkt mit der Tauchwand 8 zu verbinden, z. B. über einen an der Tauchwand angebrachten Befestigungsarm zur Verlängerung des Drehmomentes.It would also be possible to connect the container or containers 14 directly to the baffle 8 in a manner not shown, for. B. via a mounting arm attached to the baffle to extend the torque.

Um den Erfindungszweck zu erfüllen, genügt es, wenn die Tauchwand 8 im leeren Becken um einige cm angehoben wird. Die erfindungsgemässe Hebevorrichtung eignet sich für beide Arten von Tauchwänden 2 und 8.In order to fulfill the purpose of the invention, it is sufficient if the baffle 8 in the empty pool is raised by a few cm. The lifting device according to the invention is suitable for both types of baffles 2 and 8.
