Abstract

A vacuum collecting vessel is useful for collecting flushing water for cleaning sewer networks or plants for treating rainwater. Sections of sewers prone to heavy deposit formation can be flushed not only sporadically but at regular intervals with flushing water alone (waste water, ground water or the like). No mains connection is required. Flushing water is sucked under vacuum into a space (10) of variable volume between a lower base (1) and an upper extensible lid (3) of the vacuum collecting vessel. The space (10) contracts automatically on emptying.

Description

Unterdruck-Saππnβlgθfäß für Spülwasser Vacuum Saππnβlgθfäß for rinse water
Die Erfindung bezieht sich auf ein Unterdruck-Sammelgefäß für Spülwasser zum Reinigen des Kanalnetzes oder Regenwasserbehand¬ lungsanlagen.The invention relates to a vacuum collecting vessel for rinsing water for cleaning the sewer network or rainwater treatment systems.
Spülschächte zum Reinigen des Kanalnetzes oder dergleichen sind seit einer Vielzahl von Jahren bekannt. Sie werden entweder durch einen Einstau des Kanalnetzes selbstätig oder mit Hilfe einer Pumpe mit Reinwasser oder Abwasser gefüllt. Außerdem sind zur Kanalreinigung Handverfahren, Hochdruckspülgeräte und Spülwagen bekannt.Flushing shafts for cleaning the sewer network or the like have been known for a large number of years. They are either filled automatically by damming the sewer network or filled with pure water or waste water using a pump. Manual processes, high-pressure flushing devices and flushing trolleys are also known for sewer cleaning.
Ein Nachteil bei den bisher verwendeten Spülverfahren ist darin zu sehen, daß die Kanäle nur unregelmäßig per Hand oder mit Hochdruckspülverfahren gespült werden (teures und personalauf¬ wendiges Verfahren) , Spülschächte sich nur durch einen Einstau, zum Beispiel Regenereignis, füllen und erst nach Regenende automatisch entleeren (nur seltene Reinigung) oder derartige Spülschächte mit Pumpen gefüllt werden (aufwendiger Stroman¬ schluß erforderlich) .A disadvantage of the flushing methods used up to now is that the channels are only flushed irregularly by hand or using a high-pressure flushing method (expensive and labor-intensive method), flushing ducts only fill up through a backlog, for example a rain event, and only automatically after the rain has ended empty (only infrequent cleaning) or such rinsing shafts are filled with pumps (complex power connection required).
Der Erfindung liegt die Aufgabe zugrunde, die vorstehend genannten Nachteile mit Hilfe des Unterdruck-Sammengefäßes der eingangs genannten Art zu beseitigen und eine Möglichkeit zu schaffen, an ablagerungsintensiven Kanalstrecken nicht nur sporadisch, sondern in immer wiederkehrenden kurzen Abständen zu spülen. Diese Spülung sollte regelmäßig ohne Stromanschluß allein mit Spülwasser (Abwasser, Grundwasser oder dergleichen) durchgeführt werden können. Erreicht ist dieses Ziel dadurch, daß zwischen einem unteren Boden und einem oberen dehnbaren Deckel des Unterdruck-Sammelge¬ fäßes ein veränderbarer Raum geschaffen wird, in den durch Unterdruck Spülwasser gesaugt wird und der sich nach der Entleerung wieder selbstätig verkleinert.The invention has for its object to eliminate the disadvantages mentioned above with the help of the vacuum collecting vessel of the type mentioned and to create a way to not only sporadically flush on deposit-intensive channel sections, but also at recurring short intervals. This flushing should be able to be carried out regularly with flushing water alone (waste water, groundwater or the like) without a power connection. This goal is achieved in that a changeable space is created between a lower floor and an upper stretchable cover of the vacuum collecting vessel, into which rinse water is sucked in by vacuum and which automatically reduces again after emptying.
In der Zeichnung ist der Erfindungsgegenstand anhand mehrerer Ausführungsbeispiele im Querschnitt dargestellt.In the drawing, the subject matter of the invention is shown in cross-section using several exemplary embodiments.
Wie der Figur 1 für eine erste Ausführungsform der Erfindung zu entnehmen ist, besteht der untere Teil des Gehäuses des Unter¬ druck-Sammelgefäßes aus einem Boden 1 mit mittigem Ablaufröhr 2, beide aus festem Material (Stahl, Kunststoff oder dergleichen) , auf dem der obere Teil aus einem dehnbaren Deckel 3 (Gummi oder dergleichen) befestigt ist, an dem sich ein etwas kleineres Innenrohr 4 befindet, das in das Ablaufröhr 2 hineinreicht und durch eine Dichtung 5 gegen Wasserverlust abgedichtet ist. A dehnbaren Deckel 3 ist außerdem ein Anschluß für einen Saugan¬ schluß 6 und eine Befestigung 7 für einen Antrieb vorhanden. Das Ablaufrohr 2 und das Innenrohr 4 können außermittig angebracht sein. Der dehnbare Deckel 3 ist zum Teil durch eine starre Platte 8 ersetzt, an der die Befestigung 7 angreift und die das Innenrohr 4 trägt.As can be seen in FIG. 1 for a first embodiment of the invention, the lower part of the housing of the vacuum collecting vessel consists of a base 1 with a central drain pipe 2, both made of solid material (steel, plastic or the like) on which the upper part of a stretchable lid 3 (rubber or the like) is attached, on which there is a slightly smaller inner tube 4 which extends into the drain pipe 2 and is sealed by a seal 5 against water loss. A stretchable cover 3 there is also a connection for a suction connection 6 and a fastening 7 for a drive. The drain pipe 2 and the inner pipe 4 can be attached off-center. The stretchable cover 3 is partly replaced by a rigid plate 8, on which the attachment 7 engages and which carries the inner tube 4.
Figur 2 verdeutlicht ein Unterdruck-Sammelgefäß, bei dem der dehnbare Deckel 3 vollständig starr ist und der dehnbare Teil 9 sich nur auf den Mantelumfang erstreckt. Bei dem in Figur 3 gezeigten Unterdruck-Sammelgefäß ist der dehnbare Teil 9 ziehharmonikaartig gefaltet. In allen drei Figuren ist gezeigt, daß der Sauganschluß 6 im Bereich der Platte 8 in das Unter¬ druck-Sammelgefäß mündet. Es ist jedoch gleichfalls denkbar, daß dieses in den dehnbaren Deckel 3 oder auch in den Boden 1 einmündet. Das Unterdruck-Sammelgefäß wird an geeigneter Stelle, zum Beispiel in einem Kanalschacht, installiert und durch Hebung des oberen Deckels 3 mit Druckluft oder dergleichen ein Unterdruck erzeugt, der bewirkt, daß Wasser/Abwasser im Saugschlauch 6 nach oben steigt und das Gefäß (Raum 10) allmählich füllt. Gleichzei¬ tig hebt sich das Innenrohr 4 und gibt schließlich eine Öffnung 11 zur Entleerung des angesammelten Spülwassers frei. Nach mehreren weiteren Hüben, der Inhalt ist mittlerweile vollständig entleert und der Saugschlauch mit den darin befindlichen Ablagerungen leergelaufen, zieht sich das Gefäß zusammen (zum Beispiel durch Druckausgleich über Ventil 12) und der Füllvor¬ gang beginnt von neuem.FIG. 2 illustrates a vacuum collecting vessel in which the expandable cover 3 is completely rigid and the expandable part 9 only extends over the circumference of the jacket. In the vacuum collecting vessel shown in FIG. 3, the expandable part 9 is folded like an accordion. In all three figures it is shown that the suction connection 6 opens into the vacuum collecting vessel in the area of the plate 8. However, it is also conceivable that this opens into the stretchable lid 3 or in the bottom 1. The vacuum collecting vessel is installed at a suitable location, for example in a sewer shaft, and a negative pressure is generated by lifting the upper cover 3 with compressed air or the like, which causes water / waste water to rise in the suction hose 6 and the vessel (room 10 ) gradually fills up. At the same time, the inner tube 4 lifts and finally opens an opening 11 for emptying the accumulated rinsing water. After several further strokes, the contents have now been completely emptied and the suction hose with the deposits therein has run dry, the vessel contracts (for example by pressure compensation via valve 12) and the filling process begins again.
Der Unterdruck kann beispielsweise dadurch erzeugt werden, daß mit der Druckseite des Druckzylinders 13 über einen gemeinsamen Zylinderanschluß mehrere druckerzeugende Hohlkörper 14 verbunden sind. Sie sind in der Regel als Schläuche ausgebildet, die aus einem elastischen Material mit beliebigem Querschnitt bestehen. Die Schläuche werden so auf die Fahrbahn einer Straße verlegt und befestigt, daß sie von vorbeifahrenden Fahrzeugen überfahren werden müssen. Diese üben kurzfristig einen Druck auf sie aus, der dann über ein Ventil 15 je Schlauch in den Druckzylinder 13 abgeleitet wird und den Kolben 16 im Sinne einer Hubbewegung des Innenrohres 4 zum Druckäusgleichsventil 12 bewegt. Durch die Querschnittsgröße und die Anzahl der Schläuche kann je nach durchschnittlichem Verkehrsaufkommen der Druck den jeweiligen Erfordernissen angepaßt werden. Jeder Schlauch erhöht mit jedem Zusammendrücken den Druck im Druckzylinder 13 um eine gewisse Größe und hebt damit den Kolben 16 um eine definierte Strecke. Danach strömt infolge der Rückspannkraft des Schlauches 14 durch ein weiteres Ventil 17 Luft in den Schlauch nach, der wieder seine Ausgangsform einnimmt. Bei der Hubbewegung des Kolbens 16 wird"die auf dessen druckabgewandter Seite befindliche Luft im Sinne des durchgezogenen Pfeiles über das Ventil 12 aus dem Zylinder 13 ausgelassen. Kurz vor dem Anheben des Kolbens 16 gegen den oberen Zylinderanschlag überdeckt dieser den Auslaß zum Ventil 12, um schließlich beim vollständigen Anheben und damit einer Hubbewegung über den Auslaß hinweg den Druckaus¬ gleich über das Ventil 12 im Sinne des gestrichelt dargestellten Pfeiles zu ermöglichen, mit der Folge, daß sich das Gefäß zusammenzieht und der Füllvorgang von neuem beginnt.The negative pressure can be generated, for example, by connecting a plurality of pressure-generating hollow bodies 14 to the pressure side of the pressure cylinder 13 via a common cylinder connection. They are usually designed as hoses, which consist of an elastic material with any cross section. The hoses are laid and fastened on the roadway of a street in such a way that passing vehicles have to drive over them. These briefly exert a pressure on them, which is then discharged via a valve 15 per hose into the pressure cylinder 13 and moves the piston 16 in the sense of a stroke movement of the inner tube 4 to the pressure compensation valve 12. Due to the cross-sectional size and the number of hoses, the pressure can be adapted to the respective requirements, depending on the average traffic volume. Each tube increases the pressure in the pressure cylinder 13 by a certain amount with each compression and thus lifts the piston 16 by a defined distance. Then, due to the restoring force of the hose 14, air flows into the hose through a further valve 17, which returns to its original shape. During the stroke movement of the piston 16, " the air located on its side facing away from the pressure is drawn out of the valve 12 in the direction of the solid arrow Cylinder 13 omitted. Shortly before the piston 16 is raised against the upper cylinder stop, it covers the outlet to the valve 12, in order to finally enable the pressure equalization via the valve 12 in the sense of the arrow shown in dashed lines when the piston is completely lifted and thus a lifting movement beyond the outlet the result is that the vessel contracts and the filling process begins again.
Ein erfindungsgemäßes Unterdruck-Sammelgefäß für Spülwasser bereitet in der Herstellung keine Schwierigkeiten. Es kann das örtliche, in kleinen Teilmengen vorhandene geeignete Spülwasser, wie Abwasser, Grundwasser oder dergleichen Verwendung finden. Durch die ständige und nahe kontinuierliche Sammlung von Spülwasser wird das Kanalnetz immer wieder in kurzen Zeitabstän¬ den von Ablagerungen freigespült. Größere Verschmutzungen, insbesondere in Anfangshaltungen oder gefährdeten Kanalstrecken, haben keine Gelegenheit zu akkumulieren. Die Schmutzstoffe werden bereits bei Trockenwetter zur Kläranlage transportiert und gereinigt. Bei Regenfällen wird von unseren Gewässern somit eine gewaltige Schmutzfracht ferngehalten. A vacuum collecting vessel for rinsing water according to the invention presents no difficulties in production. The local, suitable rinse water, such as waste water, ground water or the like, which is present in small portions, can be used. Due to the constant and near continuous collection of rinsing water, the sewer network is flushed away from deposits again and again in short time intervals. Larger contaminations, especially in initial postures or endangered sewer sections, have no opportunity to accumulate. The pollutants are transported to the sewage treatment plant and cleaned in dry weather. When it rains, a huge amount of dirt is kept away from our waters.
