Description

Die Erfindung betrifft eine Abwasserhebeanlage mit einem Sammelbehälter für Flüssigkeiten, insbesondere Abwässer, Fäkalien oder dergleichen, mit einer Einrichtung zum Entleeren des Behälters, insbesondere einer mit einem Motor verbundenen Pumpe, welche als Motorpumpenaggregat ganz oder teilweise abgesenkt im Behälter angeordnet ist, der Behälter verfügt über mindestens je eine Zulauf- und Ablaufleitung für die Flüssigkeiten und die Abwasserhebeanlage ist mit einer Einrichtung zur Schaltung der Pumpe in Abhängigkeit von einem Flüssigkeitsniveau innerhalb des Behälters versehen.The invention relates to a wastewater lifting plant with a collecting container for liquids, especially sewage, faeces or the like, with a device for emptying the container, in particular a pump connected to a motor, which is arranged as a motor pump unit completely or partially lowered in the container, the container has at least one each inlet and outlet line for the liquids and sewage lifting plant is provided with a device for switching the pump in response to a liquid level within the container.

Solche Abwasserhebeanlagen finden häufig als Fäkalienhebeanlagen Anwendung und werden in Gebäuden und Anlagen eingesetzt, wenn ein zu förderndes Abwasser unterhalb einer sogenannten Rückstauebene anfällt. Die Rückstauebene ist gewöhnlich ein Höhenniveau eines externen Abwassersystems, welches außerhalb eines Gebäudes unter einer Straße angeordnet ist. Für einen ordnungsgemäßen Betrieb einer solchen Abwasserhebeanlage sind Einrichtungen zur Überwachung des Flüssigkeitsniveaus innerhalb des Behälters erforderlich, um ein rechtzeitiges Ein- und Ausschalten der Pumpe sicherstellen zu können.Such sewage lifting systems are often used as Fäkalienhebeanlagen application and are used in buildings and facilities when a wastewater to be pumped below a so-called backwater level. The backflow level is usually a height level of an external sewer system located outside a building under a road. For proper operation of such a sewage lifting system, means are needed to monitor the level of liquid within the container to ensure timely starting and stopping of the pump.

Durch die DE-A 33 11 980 ist eine solche Abwasserhebeanlage zum Sammeln und zum Abpumpen von Schmutzwasser bekannt. Dazu verfügt die Abwasserhebeanlage über einen Sammelbehälter und einer darin befindlichen Motorpumpeneinheit, die durch eine pneumatische Steuerglocke ihre Schaltsignale erhält. Hierbei handelt es sich um ein Staurohr, dessen Luftvolumen beim Ansteigen eines Behälterinhaltes eingeschlossen und damit im Staurohr einen statischen Druck erzeugt. Dieser Druck wird von einem Drucksensor erfasst und dessen Wert in eine Füllstandshöhe des jeweiligen Behälters umgerechnet. Solche Staudrucksysteme, die es in unterschiedlichsten Formen gibt, sind jedoch anfällig gegen das innerhalb des Behälters befindliche Schmutzwasser und dessen Bestandteile. Da ein Ausfall eines solchen relevanten Bauteiles für die gesamte Anlage und das davon entsorgte Gebäude von grundlegender Bedeutung ist, sind erhebliche Wartungs- und Instandhaltungsarbeiten notwendig, um dessen Funktionalität zu gewährleisten. Um Leckverluste oder Ablagerungen innerhalb eines solchen Staurohrsystems zu vermeiden, muss das Rohr in aufwendiger Weise durch separate Steuerungselemente kontinuierlich freigefahren werden oder mit Hilfe einer Lufteinperlung die vorstehenden Nachteile vermieden werden.By the DE-A 33 11 980 Such a wastewater lifting plant is known for collecting and pumping out dirty water. For this purpose, the wastewater lifting plant has a collecting container and a motor pump unit located therein, which receives its switching signals by a pneumatic control bell. This is a pitot tube whose volume of air trapped as the contents of a container rise and thus creates a static pressure in the pitot tube. This pressure is detected by a pressure sensor and its value is converted into a filling level of the respective container. However, such dynamic pressure systems, which exist in a variety of forms, are susceptible to being within the container Dirty water and its components. Since a failure of such a relevant component is of fundamental importance to the entire installation and the building disposed of, significant maintenance and servicing work is required to ensure its functionality. In order to avoid leakage or deposits within such a pitot tube system, the tube must be continuously freewheeled in a complex manner by separate control elements or by means of a Lufteinperlung the above disadvantages are avoided.

Alternativ hierzu haben sich am Markt zur Steuerung der Pumpe Schwimmerschalter durchgesetzt, wie sie beispielsweise durch die DE-A 3 430 527 bekannt sind. In Abhängigkeit vom Flüssigkeitsniveau innerhalb des Behälters löst ein von einem Schwimmer betätigter Schalter die notwendigen Ein- und Ausschaltbewegungen einer Pumpe aus. Aber auch diese Schwimmerschalter sind durch Ablagerungen oder feste Bestandteile in der Flüssigkeit in ihrer Funktion eingeschränkt oder gefährdet.Alternatively, have on the market to control the pump float switch prevailed, as for example by the DE-A 3 430 527 are known. Depending on the level of liquid within the container, a switch actuated by a float triggers the necessary switching on and off movements of a pump. But even these float switches are limited by deposits or solid components in the liquid in their function or endangered.

Die DE-A-31 13 903 offenbart die Merkmale gemäß dem Oberbegriff des Anspruchs 1.The DE-A-31 13 903 discloses the features according to the preamble of claim 1.

Der Erfindung liegt daher das Problem zugrunde, eine Niveauerfassung zu entwickeln, durch die zuverlässig der Füllstand im Behälter problemlos erfasst und auf aufwendige, der Flüssigkeit ausgesetzte zusätzliche Schutzeinrichtungen verzichtet werden kann.The invention is therefore based on the problem to develop a level detection, reliably detected by the level in the tank problems and can be dispensed with elaborate, exposed to the liquid additional protective devices.

Die Lösung des Problems sieht vor, dass ein- oder mehrere Sensoren an der Außenseite der elastisch nachgiebigen Behälterbodenfläche angeordnet sind und deren Verformung messen.The solution to the problem provides that one or more sensors are arranged on the outside of the resilient container bottom surface and measure their deformation.

Mit dieser Lösung wird in einfacher Weise das Problem von verschmutzenden Füllstandssensoren umgangen. Da die den Verformungsgrad eines Behälterbodenteiles erfassenden Sensoren auf der Außenseite des Behälters angebracht sind, sind sie den schädigenden Einflüssen eines Abwassers vollständig entzogen. Durch die Anordnung des Behälterbodenteiles mit einem Abstand zu einer Aufstellfläche für die Abwasserhebeanlage, ist dazwischen ein Hohlraum ausgebildet. Dieser Hohlraum ist gleichzeitig ein Schutzraum für die äußeren Sensoren gegenüber äußeren mechanischen Einflüssen und verhindert Beschädigungen des elastisch nachgiebigen Behälterbodenteiles.With this solution, the problem of polluting level sensors is easily avoided. Since the sensors detecting the degree of deformation of a container bottom part are mounted on the outside of the container, they are completely removed from the harmful effects of a wastewater. By arranging the container bottom part with a distance to a footprint for the sewage lifting unit, a cavity is formed therebetween. This cavity is at the same time a protective space for the external sensors in relation to external mechanical ones Influences and prevents damage to the resilient container bottom part.

Der Behälterboden oder eine Teilfläche davon sind so gestaltet, dass mindestens ein Sensor an einer Behälterboden-Messstelle angeordnet ist, an der bei maximal gefüllten Behälter eine auswertbare Verformung auftritt. Ebenso ist vorgesehen, dass mindestens ein Sensor an einer Behälterboden-Messstelle angeordnet ist, an der bei minimal gefüllten Behälter eine auswertbare Verformung auftritt. Somit wird die Generierung von Sensorsignalen gewährleistet, mit denen zuverlässig die notwendigen Einschalt-, Abschalt- oder Alarmpunkte einer Abwasserhebeanlage bzw. der damit verbundenen Pumpe und die Abhängigkeit vom jeweiligen Füllstand im Behälter erfasst werden können. Die dabei an einer Messstelle maximal auftretende Verformung eines belastenden Behälters liegt innerhalb der jeweils zulässigen Werkstoffwerte. Dies wird erreicht durch eine entsprechende Formgebung des Behälterbodens oder eines Teiles davon.The container bottom or a partial surface thereof are designed so that at least one sensor is arranged at a container bottom measuring point, at which an evaluable deformation occurs at the maximum filled container. Likewise, it is provided that at least one sensor is arranged at a container bottom measuring point, at which an evaluable deformation occurs at minimally filled container. Thus, the generation of sensor signals is ensured with which reliably the necessary switch-on, shutdown or alarm points of a wastewater lifting plant or the associated pump and the dependence on the respective level in the container can be detected. The maximum deformation occurring at a measuring point of a loading container is within the respective permissible material values. This is achieved by a corresponding shaping of the container bottom or a part thereof.

Ebenso ist es möglich, in dem Behälterboden ein elastisch nachgiebiges Element dichtend und flexibel gehalten anzuordnen und mit mindestens einem Sensor zu verbinden. Ein Sensorsignal über einen jeweiligen Füllstand wird von den an sich bekannten Auswerteeinheiten solcher Abwasserhebeanlagen für eine Pumpensteuerung verarbeitet.Likewise, it is possible to arrange in the container bottom an elastically yielding element sealingly and flexibly held and to connect with at least one sensor. A sensor signal on a respective level is processed by the known evaluation of such wastewater lifting systems for a pump control.

Nach einer anderen Ausgestaltung sind ein oder mehrere Sensoren auswechselbar befestigt. Dies kann mittels einfacher Schnapp- oder Klemmverbindungen erfolgen und vereinfacht die Herstellung bei gleichzeitiger leichten Austauschbarkeit eines Sensors in einem eventuellen Wartungsfall.According to another embodiment, one or more sensors are mounted interchangeable. This can be done by means of simple snap or clamp connections and simplifies the production while easy replacement of a sensor in a possible maintenance case.

In der Fig. 1 ist ein Querschnitt durch ein Gebäude gezeigt, in dessen Untergeschoss eine sanitäre Einrichtung dargestellt ist. Einer Abwasserhebeanlage 1 fließen die Abwässer der sanitären Einrichtung sowie andere zu entsorgende Flüssigkeiten zu und werden darin gesammelt, bis ein ausreichend hoher Füllstand für eine fallweise Förderung erreicht ist. Die Abwasserhebeanlage besteht aus einem flüssigkeits- und geruchsdichten Behälter 2 und einer darin dichtend angeordneten Pumpe 3 in Form eines Motorpumpenaggregates, das für die störungsfreie Förderung solcher Flüssigkeiten ausgelegt ist. Über eine Zulaufleitung 4 wird ein anfallendes Abwasser in den Behälter 2 eingeleitet und über eine Ablaufleitung 5 in Form einer Druckleitung über eine Rückstauebene 6 gefördert, um von dort in eine Kanalisation 7 abzufließen. Im allgemeinen ist ein solcher Behälter 2 mit einer - hier nicht dargestellten - Belüftung versehen, wodurch eine Gasabfuhr erreicht und die Entstehung eines .Überdruckes im Behälter 2 verhindert wird. Ein solcher Lüftungsanschluss wird meistens über das Dach eines Gebäudes geführt, um Geruchsbelästigungen zu vermeiden.In the Fig. 1 is a cross section through a building shown in the basement of a sanitary facility is shown. A sewage lifting plant 1, the sewage of the sanitary device and other liquids to be disposed of flow and are collected in it until a sufficiently high level for a case by case promotion is achieved. The sewage lifting plant consists of a liquid and odor-tight container 2 and a sealingly arranged therein pump 3 in the form of a motor pump unit, which is designed for the trouble-free promotion of such liquids. Via a feed line 4, a waste water is introduced into the container 2 and conveyed via a drain line 5 in the form of a pressure line via a backflow level 6, to drain from there into a sewer system 7. In general, such a container 2 is provided with a - not shown - ventilation, whereby a gas removal is achieved and the emergence of a .Überdruckes in the container 2 is prevented. Such a ventilation connection is usually led over the roof of a building in order to avoid odor nuisance.

Die Fig. 2 zeigt in vergrößerter Darstellung eine Seitenansicht einer solchen Abwasserhebeanlage nach dem Stand der Technik. Der die Abwässer sammelnde Behälter 2 ist hermetisch geschlossen, um deren Austritt und um Geruchsbelästigungen in einem Gebäude zu vermeiden. Der Behälter 2 ist mit einer Zulaufleitung 4 und mit einer Ablaufleitung 5 verbunden, wobei in letzterer ein Rückschlagventil 8 und ein Absperrventil 9 angeordnet sind. In dem Behälter 2 teilweise eingetaucht ist eine elektrisch angetriebene Pumpe 3. Sie fördert in die Ablaufleitung 5 und wird immer nur bei Bedarf eingeschaltet. Dazu ist sie mit einem Schaltgerät 10 zur Steuerung und Überwachung des Betriebes einer solchen Abwasserhebeanlage verbunden.The Fig. 2 shows an enlarged view of a side view of such a sewage lifting plant according to the prior art. The collecting the waste water tank 2 is hermetically sealed to prevent their escape and odors in a building. The container 2 is connected to a supply line 4 and a drain line 5, wherein in the latter a check valve 8 and a check valve 9 are arranged. Partially immersed in the container 2 is an electrically driven pump 3. It delivers into the drain line 5 and is always turned on only when needed. For this purpose, it is connected to a switching device 10 for controlling and monitoring the operation of such a wastewater lifting plant.

Beispielhaft ist in gestrichelter Darstellung als Stand der Technik ein Schwimmerschalter 11 gezeigt. Mit einem solchen innerhalb des Behälters 2 angeordneten Schwimmerschalter wird bei Erreichen von drei strichpunktiert dargestellten Behälter-Füllständen PA, PE und A ein Signal an das Schaltgerät 10 übermittelt und von diesem eine Schaltfunktion für die Abwasserhebeanlage ausgelöst. Hierbei steht die unterste Linie PA für die Schaltfunktion "Pumpe aus". Der schwenkbar gelagerte Schwimmerschalter hängt dann herab. Bei zunehmendem Flüssigkeitsstand bewegt sich der Schwimmer nach oben, bis er bei einem Behälter- Füllstand PE eine Schaltstellung erreicht, die der Schaltfunktion "Pumpe ein" entspricht und ein Einschalten der Pumpe durch das Schaltgerät 10 zur Folge hat. Und bei Erreichen des obersten, dritten Behälter - Füllstandes A, einem unzulässigen Betriebszustand, wird eine Alarmfunktion auslöst. Strömt in den Behälter eine größere Menge an Abwasser ein, als von der Pumpe weggefördert werden kann, dann verhindert die Alarmfunktion ein Überfluten der Kellerräume durch ein Zurückströmen und einen Austritt aus den Zuläufen der angeschlossenen Einrichtungen. Dieser Zustand kann auch bei einem Ausfall der Pumpe eintreten. Es ist daher auf eine ständige Funktionsbereitschaft eines solchen innerhalb des Behälters angeordneten Schwimmerschalter zu achten.By way of example, a float switch 11 is shown in dashed representation as prior art. With such arranged within the container 2 float switch a signal is transmitted to the switching device 10 upon reaching three tank-level container levels shown P A , P E and A and triggered by this a switching function for the wastewater lifting plant. Here, the lowest line P A stands for the switching function "pump off". The pivotally mounted float switch then hangs down. Moving with increasing liquid level the float upwards until it reaches a switching position at a container level P E , which corresponds to the switching function "pump on" and has a switching on of the pump by the switching device 10 result. And when the upper, third tank level A, an impermissible operating state, is reached, an alarm function is triggered. If a larger amount of wastewater enters the tank than can be pumped away, the alarm function prevents flooding of the basement rooms by a backflow and an exit from the inlets of the connected equipment. This condition may occur even if the pump fails. It is therefore important to ensure a constant functional readiness of such a float switch arranged inside the container.

Die Fig. 3 zeigt dagegen als Verbesserung der bisherigen Lösungen einen vergrößerten Ausschnitt vom Behälter 2 in Form eines Querschnitts durch einen Behälterboden 12. Der Boden 12 des Behälters 2 weist einen Teilbereich 12.1 auf, der oberhalb und im Abstand zu einer Aufstellebene 13 für die Abwasserhebeanlage angeordnet ist Dadurch ist zwischen der Aufstellebene 13 und dem darauf mit der Bodenfläche 12 aufliegenden Behälter 2 ein ganz oder teilweise abgeschlossener Hohlraum 16 ausgebildet. Dieser schirmt den nachgiebigen Teilbereich 12.1 des Behälterbodens 12 vor äußeren Einflüssen ab. Der Teilbereich 12.1 des Behälterbodens 12 ist elastisch nachgiebig ausgebildet und an seiner Außenseite 14 sind ein oder mehrere Sensoren 15 angeordnet. Der Abstand zwischen den an tiefster Stelle montierten Sensor 15 und der Aufstellebene 13 ist so groß bemessen, dass bei vollständiger Füllung eines Behälters 2 eine Berührung mit der Aufstellebene 13 sicher vermieden wird.The Fig. 3 shows, however, as an improvement of the previous solutions an enlarged section of the container 2 in the form of a cross section through a container bottom 12. The bottom 12 of the container 2 has a portion 12.1, which is arranged above and at a distance to a mounting plane 13 for the sewage lifting system is characterized formed between the mounting plane 13 and the resting thereon with the bottom surface 12 container 2 a completely or partially closed cavity 16. This shields the resilient portion 12.1 of the container bottom 12 from external influences. The portion 12.1 of the container bottom 12 is elastically yielding and on its outer side 14, one or more sensors 15 are arranged. The distance between the sensor 15 mounted at the lowest point and the mounting plane 13 is dimensioned so large that upon complete filling of a container 2, contact with the mounting plane 13 is reliably avoided.

Der jeweilige Füllungsgrad eines Behälters 2 wirkt in Form einer Flüssigkeitssäule verformend auf die elastisch nachgiebig ausgebildete Teilfläche 12.1 ein. Deren jeweiligen Verformungsgrad erfasst mindestens ein äußerer Sensor 15. Dessen Signal wird mit Hilfe des Schaltgerätes 10 in ein Füllstandssignal umgewandelt, angezeigt und / oder zur Steuerung der Pumpe 3 verwendet.The respective degree of filling of a container 2 acts in the form of a liquid column deforming on the elastically yielding part surface 12.1. Its respective degree of deformation detected at least one outer sensor 15. Its signal is converted by means of the switching device 10 in a level signal, displayed and / or used to control the pump 3.

Aufgrund eines sich innerhalb des Behälters einstellenden Flüssigkeitsniveaus und der daraus resultierenden Flüssigkeitssäule wird die Behälterbodenfläche unterschiedlich verformt oder ausgelenkt. Die Größenordnungen dieser Verformungen liegen innerhalb der zulässigen Werte des jeweils für den Behälter 2 verwendeten Werkstoffes. Somit wirken auf den Sensor 15 Formänderungsarbeiten ein, die als ein direktes Maß für den Füllstand innerhalb des Behälters 2 verwendet werden. Da der Sensor 15 in einem Hohlraum 16 angeordnet ist, der zwischen der Aufstellebene 13 und dem demgegenüber erhöhten Behälterbodenteil 12.1 ausgebildet ist, ergibt sich ein zusätzlicher Schutzraum für den Sensor 15. Die - hier nicht dargestellten - Signalleitungen des Sensors 15 befinden sich ebenfalls vollständig außerhalb der Abwasserhebeanlage und sind deshalb problemlos mit dem Schaltgerät 10 zu verbinden. Die bisher üblichen Leitungsdurchführungen im Behälter 2 entfallen damit vollständig. Dies stellt ein zusätzliches Sicherheitsmerkmal für einen sicheren Betrieb dar.Due to an adjusting within the container liquid level and the resulting liquid column, the container bottom surface is deformed or deflected differently. The orders of magnitude of these deformations are within the permissible values of the material used for the container 2. Thus, on the sensor 15 strain acting, which are used as a direct measure of the level within the container 2. Since the sensor 15 is arranged in a cavity 16 which is formed between the mounting plane 13 and the container bottom part 12.1, which is raised in contrast thereto, an additional protection space for the sensor 15 results. The signal lines of the sensor 15, which are not shown here, are also completely outside the sewage lifting unit and are therefore easy to connect to the switching device 10. The usual cable bushings in the container 2 thus eliminated completely. This provides an additional safety feature for safe operation.

Die Fig. 4 zeigt eine andere Ausbildungsform der Bodenfläche 12. Hier ist im nachgiebigen Behälterbodenteil 12.1 zusätzlich ein elastisch nachgiebig ausgebildeter Behälterbodenteil 12.2 als eine flüssigkeitsdicht eingesetzte Membran gestaltet. Dieser Behälterbodenteil 12.2 kann aus einem Gummimaterial bestehen, als aus einem elastischen Kunststoff bestehende Platte ausgebildet sein, als eine metallische Membran oder als eine Kombination solcher Materialien gestaltet sein. Der jeweilige Flüssigkeitsstand im Behälter 2 lenkt den Behälterbodenteil 12.2 in Richtung auf die Außenseite 14 aus. Ein an der Außenseite 14 angeordneter und mit dem Behälterbodenteil 12.2 in Wirkverbindung stehender Sensor 15 generiert aus der Auslenkung ein Sensorsignal.The Fig. 4 shows another embodiment of the bottom surface 12. Here, in the resilient container bottom part 12.1 additionally designed an elastically yielding container bottom part 12.2 as a liquid-tight membrane used. This container bottom part 12.2 may be made of a rubber material, may be formed as a plate made of an elastic plastic, designed as a metallic membrane or as a combination of such materials. The respective liquid level in the container 2 deflects the container bottom part 12. 2 in the direction of the outside 14. A sensor 15, which is arranged on the outer side 14 and is in operative connection with the container bottom part 12.2, generates a sensor signal from the deflection.

Fig. 5 zeigt die Anordnung des Sensors 15 in einem auswechselbar gestalteten Gehäuse 17, das mit bekannten Mitteln 18 am Behälterbodenteil 12.1 befestigt sein kann. Im gezeigten Ausführungsbeispiel dient es gleichzeitig zur Befestigung des Behälterbodenteiles 12.2. Und der Sensor 15 kann als ein induktives System für eine Wegmessung oder als ein Piezoquarz für eine Druckmessung ausgelegt sein. Fig. 5 shows the arrangement of the sensor 15 in a replaceable designed housing 17, which may be secured by known means 18 on the container bottom part 12.1. In the embodiment shown, it also serves for fastening the container bottom part 12.2. And the sensor 15 may be designed as an inductive system for a displacement measurement or as a piezo-quartz for a pressure measurement.
