Abstract

The siphon pipe (2) is connected at its highest point to an vacuum container (3) for the collection of air from the waste water. The container is connected to a pump (7) for air suction. The pump is controlled (10) via immersed level detecting electrodes (8,9), dependant upon the collected air. The container is connected to the siphon pipe via a connection part (4), which decreases in size. The sensors are formed by two dipped electrodes. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung für Heberleitungen zum Heben von Abwasser über ihren Spiegel durch Luftdruck, die als Bypass für zu sanierende Sielleitungen angeordnet sind und eine kontinuierliche energielose Förderung bewirken.The invention relates to a device for Lifter lines for lifting sewage over your Mirrors by air pressure acting as a bypass for too remedial sewer lines are arranged and a effect continuous energy-free promotion.

Anordnungen dieser Art sind für diesen Einsatzzweck bekannt (Siehe z.B.-GB-A-2 239 269). Es hat sich aber gezeigt, daß in der Praxis durch die mitgeführte Luft, insbesondere bei geringer Strömung, es zum Abriß der Förderung kommt. Hierbei sammeln sich in der Heberleitung Luftblasen, die den Hebereffekt unterbrechen. In diesem Fall wird dann über ein erneutes Ansaugen des Abwassers durch entsprechende Aggregate der Hebervorgang relativ aufwendig wieder in Betrieb gesetzt.Arrangements of this type are known for this purpose (see e.g. GB-A-2 239 269). However, it has been shown that in practice due to the entrained air, especially at low levels Flow, there is a demolition of the funding. Here Air bubbles collect in the lifter line, which Interrupt lifting effect. In this case, then a renewed suction of the waste water by appropriate Aggregates the lifting process back in relatively expensive Operation set.

Die Aufgabe der Erfindung ist es, eine gattungsgemäße Anordnung zu verbessern und die anfallende Luft zu separieren sowie eine Abführung zu gewährleisten und einen ordnungsgemäßen Betrieb zu ermöglichen.The object of the invention is a generic Improve arrangement and increase the amount of air separate and ensure a discharge and to enable proper operation.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß die Heberleitung im Bereich ihres höchsten Punktes mit einen Unterdruckbehälter zum Sammeln von Luft aus dem Abwasser angeordnet ist, der mit einer Pumpe zum Absaugen der aufgenommenen Luft verbunden ist, wobei die Pumpe über Sensoren entsprechend der gesammelten Luft wasserstandsabhängig steuerbar ist.According to the invention, this object is achieved by that the lifter line is at its highest Point with a vacuum container for collecting Air from the wastewater is arranged with a Pump connected to extract the intake air is, the pump via sensors according to the collected air is controllable depending on the water level.

Hierdurch ist es möglich, energiearm die anfallende Luft zu separieren und eine kontinuierliche Abwasserförderung zu ermöglichen.This makes it possible to use low energy Separate air and continuous wastewater production to enable.

Um einen Selbstreinigungsvorgang zu verbessern, ist vorgesehen, daß der Unterdruckbehälter über eine konisch in Richtung des Unterdruckbehälters sich verengendes Verbindungsstück mit der Heberleitung verbunden ist.To improve a self-cleaning process is provided that the vacuum container via a conically narrowing in the direction of the vacuum container Connection piece connected to the lifting line is.

Weiterhin wird vorgeschlagen, daß der Eintrittsbereich des Unterdruckbehälters nach dem Verbindungsstück sich in Richtung des Unterdruckbehälters erweitert.It is also proposed that the entry area of the vacuum tank after the connector itself extended towards the vacuum tank.

Eine einfache Steuerung wird dadurch ermöglicht, daß die Sensoren zur Steuerung der Pumpe für den Unterdruck durch zwei beabstandete Tauchelektroden gebildet sind.A simple control is made possible by the fact that the sensors to control the vacuum pump are formed by two spaced electrodes.

In der Zeichnung ist ein Ausführungsbeispiel einer Heberanlage für eine zu sanierende Abwasserleitung schematisch dargestellt.In the drawing, an embodiment is one Lifter system for a sewage pipe to be renovated shown schematically.

Hierbei ist eine zu sanierende Abwasserleitung 1 mit einer Heberleitung 2 als Bypass angeordnet. Es ist im Bereich des höchsten Punktes der Heberleitung 2 über ein Verbindungsstück 4 ein Unterdruckbehälter 3 angeschlossen.A sewage pipe 1 to be renovated is included a siphon line 2 arranged as a bypass. It is in Range of the highest point of the lifting line 2 over a connector 4 a vacuum tank 3 connected.

Das Verbindungsstück 4 verengt sich konisch in Richtung des Unterdruckbehälters 3 und ist über ein zwischengeschaltetes Absperrventil 5 mit dem Unterdruckbehälter 3 verbunden, der sich in diesem Eintrittsbereich 11 konisch erweitert. The connector 4 narrows conically in the direction of the vacuum container 3 and is via an intermediate Shut-off valve 5 with the vacuum tank 3 connected in this entry area 11 flared.

Der Unterdruckbehälter 3 ist über eine Absaugleitung 6 mit einer Pumpe 7 zur Erzeugung eines Unterdruckes verbunden. Zusätzlich sind Tankelektroden 8,9 im Unterdruckbehälter 3 angeordnet, die eine Minimal- und Maximalfüllhöhe des Abwassers erfassen und über eine zugeordnete Steuerung 10 die Pumpe 7 zur Unterdruckerzeugung ansteuern.The vacuum container 3 is via a suction line 6 connected to a pump 7 for generating a negative pressure. In addition, tank electrodes 8.9 are in the vacuum container 3 arranged, the minimum and Record the maximum fill level of the wastewater and use a assigned control 10, the pump 7 for generating negative pressure head for.

Die im Abwasser störende Luft wird durch die Aufstiegseigenschaften dem Unterdruckbehälter 3 zugeführt, wodurch das im Unterdruckbehälter 3 durch Unterdruck gesammelte Abwasser verdrängt wird. Nach Unterschreiten der Minimalfüllhöhe wird über die Tankelektrode 9 die Pumpe 7 in Betrieb gesetzt, die Luft abgeführt und die Maximalfüllhöhe über die Elektrode 8 im Unterdruckbehälter 3 wieder eingestellt. Hierdurch wird durch Abführung der Luft eine zuverlässige Förderung des Abwassers nach den Hebereffekt energiearm gewährleistet.The air disturbing in the wastewater is due to the ascent properties supplied to the vacuum tank 3, whereby that collected in the vacuum container 3 by vacuum Wastewater is displaced. After falling short the minimum fill level is the tank electrode 9 Pump 7 started, the air removed and the Maximum fill level via the electrode 8 in the vacuum container 3 set again. This will result in dissipation the air reliably pumps waste water Low energy guaranteed after the lifting effect.
