Abstract

Method of emptying a refuse-collecting container by air evacuation, the container (1) being connected via a first valve (4) to a refuse feed line (3), for example in the form of a refuse shaft arranged in a multi-family dwelling. The refuse-collecting container can be connected via a second, valve-controlled aperture in the base of the container to a refuse removal line (5), which for its part can be connected to a collecting chamber located in a refuse vehicle, it being possible for the latter chamber to be made empty of air in order to achieve a necessary suction effect. The interior of the container can be connected to atmospheric air by at least one valve-controlled aperture (8, 9). On emptying the container, the first valve is kept open during a first evacuation stage. In a second evacuation stage, after at least a partial vacuum has been achieved in the container, atmospheric air is introduced below the refuse bags which have collected in the collecting zone in the container, and in a third evacuation stage a further stream of atmospheric air is introduced into the interior of the container above the refuse collecting zone. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Entleeren eines Müllsammelbehälters durch Luftevakuierung, wobei der Müllsammelbehälter über ein erstes Ventil an eine Müllzufuhrleitung, beispielsweise in Form eines in einem Mehrfamielienhaus angeordneten Müllschachtes angeschlossen ist und der Müllsammelbehälter über eine zweite ventilgesteuerte Öffnung im Boden des Behälters an eine Müllentnahmeleitung und diese ihrerseits an eine mobile Müllsammelkammer anschliessbar ist, deren Luftvolumen zwecks Erzielung einer notwendigen Saugwirkung evakuiert werden kann, und wobei das innere des Behälters über wenigstens eine ventilgesteuerte Öffnung an die Atmosphärsluft anschliessbar ist.The invention relates to a method for emptying a refuse collection container by air evacuation, the refuse collection container being connected via a first valve to a refuse supply line, for example in the form of a refuse shaft arranged in a multi-family house, and the refuse collection container being connected to one via a second valve-controlled opening in the bottom of the container Waste removal line and this in turn can be connected to a mobile waste collection chamber, the air volume of which can be evacuated for the purpose of achieving a necessary suction effect, and the interior of the container can be connected to the atmospheric air via at least one valve-controlled opening.

Ein derartiger Müllsammelbehälter für die Entleerung mittils Vakuum ist durch EP 84 850 111-0 bekannt.Such a waste collection container for emptying by means of vacuum is known from EP 84 850 111-0.

Das zur Entleerung dieses bekannten Müllsammelbehälters verwendete Verfahren ist jedoch der Kritik offen und ergibt eine Reihe von Nachteilen.However, the method used to empty this known waste collection container is open to criticism and has a number of disadvantages.

Da die Entleerung des Müllsammelbehälters von einem Müllabfuhrfahrzeug ausserhalb des Müllraumes gesteuert wird, muss eine vollständige Entleerung des Systemes sichergestellt werden können, so dass nach beendigter Entleerungsphase eine störungsfreie Funktion des Müllsammelbehälters garantiert werden kann. Da eine Entleerung des Müllsammelbehälters meistens in vorbestimmten Zeitabständen festgelegt ist - gewöhnlicherweise einmal pro Woche - kommt es vor, dass der Sammelbehälter schneller als berechnet gefüllt wird und dass die meistens hierbei verwendeten Müllbeutel sich hierbei oberhalb des Zufuhrventils im unteren Teil des Müllschachtes anstauen und ansammeln und dadurch eine Verstopfung des unteren Schachtteiles bewirken.Since the emptying of the garbage collection container is controlled by a garbage collection vehicle outside the garbage room, it must be possible to ensure that the system is completely emptied, so that after the emptying phase has ended, trouble-free functioning of the garbage collection container can be guaranteed. Since emptying of the waste collection container is usually determined at predetermined time intervals - usually once a week - it happens that the collection container is filled faster than calculated and that the waste bags mostly used here accumulate and accumulate above the feed valve in the lower part of the waste shaft cause a blockage of the lower part of the shaft.

In der obigen EP-Patentschrift wird vorgeschrieben, dass der Anschluss des Müllsammelbehälters an die Zufuhrleitung, d.h. an den Müllschacht, während des Entleerungsverfahrens gänzlich geschlossen sein soll - diese Massnahme sei gemäss diesem bekannten Stand der Technik notwendig, um eventuelle Schaden bei Personen, die den Müllschacht während der Entleerung des Müllsammelbehälters verwenden, zu eliminieren.In the above EP patent it is prescribed that the connection of the waste collection container to the supply line, i.e. to the garbage chute during the emptying process should be completely closed - this measure is necessary according to this known state of the art to eliminate any damage to people who use the garbage chute while emptying the garbage collection container.

Da eine Inspektion des unteren Schachtteiles, also des Schachtteiles, der oberhalb des ersten Ventiles des Müllsammelbehälters liegt, aus oben genannten Gründen nach abgeschlossener Entleeerungsphase des Sammelbehälters nicht durchgeführt werden kann, kann eine etwaige Verstopfung des Schachtes nicht festgestellt werden - wodurch naturgemäss beträchtliche Betriebsstörungen bei der weiteren Verwendung des Müllsammelbehälters entstehen.Since an inspection of the lower part of the shaft, i.e. the part of the shaft that lies above the first valve of the refuse collection container, cannot be carried out after the emptying phase of the collection container has been completed for the reasons mentioned above, any blockage of the shaft cannot be determined - which naturally leads to considerable malfunctions in the further use of the waste collection container arise.

Ausserdem wird bei diesem bekannten Entleerungsverfahren eine momentane Zufuhr von Atmosphärsluft in den luftentleerten Müllsammelbehälter vorgeschlagen, eine Massnahme, die zu beträchtlichen Materialbeaufschlagungen führt und auch zu Schallstössen, die sich im ganzen System fortpflanzen.In addition, this known emptying method proposes a current supply of atmospheric air into the air-emptied waste collection container, a measure which leads to considerable material impacts and also to noise impacts which propagate throughout the system.

Ausserdem hat sich erwiesen, dass der zugeführte Atmosphärenluftstrom bei der bekannten Vorrichtung nicht nur gegen die Bodenschicht des im Behälter aufgesammelten Mülls gerichtet werden darf - ein solcher Luftstrom ergibt nämlich grösstenteils lediglich eine Turbulenz der Müllbeutel im Behälter, wohingegen die gewünschte Entleerung der Müllbeutel durch die Entnahmeleitung nicht erreicht wird.In addition, it has been shown that the supplied atmospheric air flow in the known device must not only be directed against the bottom layer of the garbage collected in the container - such an air flow largely results in only turbulence of the garbage bags in the container, whereas the desired emptying of the garbage bags by the extraction line is not reached.

Falls nun die Atmosphärenluftstrom lediglich über eine im oberen Teil des Behälters vorhandene Öffnung zugeführt wird, ist die gewünschte Entleerungshilfe für die am Behältersboden vorhandenen Müllbeutel nicht erreichbar.If the atmospheric air flow is now only supplied via an opening in the upper part of the container, the desired emptying aid for the garbage bags on the container bottom cannot be reached.

Aufgabe des erfindungsgemäss vorgeschlagenen Verfahrens ist nun, die obigen Nachteile der bisher bekannten Technik bei einem Entleeren eines solchen Müllsammelbehälters zu eliminieren und ein Entleerungsverfahren zu schaffen, das eine optimale Entleerung des Müllsammelbehälters unter akzeptierbaren Materialbeanspruchungen sicherstellt und auch eine störungsfreie Wiederverwendung des Müllsammelbehälters dadurch ergibt, dass gegebenenfalls im unteren Schachtteil bei der Entleerung des Müllsammelbehälters vorhandene Verstopfungen in effektiver Weise aufgelöst werden und auch die hier befindlichen Müllbeutel bei der Entleerung in den Müllsammelbehälter eingesaugt werden.The object of the method proposed according to the invention is now to eliminate the above disadvantages of the previously known technology when emptying such a refuse collection container and to create an emptying process which ensures optimal emptying of the refuse collection container under acceptable material stresses and also results in trouble-free reuse of the refuse collection container in that If necessary, existing blockages in the lower part of the shaft when emptying the refuse collection container can be effectively removed and also the refuse bags located here can be sucked into the refuse collection container during emptying.

Eine weitere Aufgabe des erfindungsgemäss vorgeschlagenen Verfahrens ist die Schaffung einer optimalen Entleerung des Müllsammelbehälters durch die erfindungsgemäss vorgeschlagene Steuerung der Atmosphärenluft.A further object of the method proposed according to the invention is to create an optimal emptying of the refuse collection container by the control of the atmospheric air proposed according to the invention.

Diese Aufgabe wird bei einem gattungsgemäss beschriebenen Verfahren hauptsächlich durch folgende Evakuierungsstufen nach Anschluss des Müllsammelbehälters an die mobile Sammelkammer erreicht:

  • a) dass man während einer ersten Evakuierungsstufe das erste Ventil offen hält,
  • b) dass man während einer zweiten Evakuierungsstufe, nach Erzielung von wenigstens einem Teilvakuum im Behälter, Atmosphärenluft unter die im Behälter angesammelten Müllbeutel einführt,
  • c) dass man in einer dritten Evakuierungsstufe einen weiteren Strom von Atmosphärenluft zum Inneren des Behälters in einem Niveau oberhalb des Müllsammelraumes einführt.
In a method of the generic type, this task is mainly achieved by the following evacuation stages after connecting the waste collection container to the mobile collection chamber:
  • a) that the first valve is kept open during a first evacuation stage,
  • b) that atmospheric air is introduced under the garbage bags collected in the container during a second evacuation stage after at least a partial vacuum has been achieved in the container,
  • c) that in a third evacuation stage, a further stream of atmospheric air is introduced to the interior of the container at a level above the refuse collection area.

Dadurch, dass das erste Ventil zu Beginn der Entleerung offen ist, wird bewirkt, dass gegebenenfalls oberhalb des ersten Ventiles im Müllschacht befindlicher Müll in den Behälter hineingezogen wird.The fact that the first valve is open at the start of emptying has the effect that any garbage located above the first valve in the refuse shaft is drawn into the container.

Das Einführen eines ersten Atmosphärenluftstromes in den Behälter über eine ventilgesteuerte Öffnung im Boden des Behälters, d.h. unter dem Müllsammlungsteil des Behälters, ergibt ein Anheben und eine Turbulenz der Müllbeutel, und durch eine etwa gleichzeitige Zufuhr eines zweiten Atmosphärenluftstromes zum Inneren des Behälters und oberhalb der Müllsammelzone ergibt sich eine optimale Entleerung des Mülls.Introducing a first stream of atmospheric air into the container through a valve-controlled opening in the bottom of the container, i.e. under the garbage collection part of the container, there is a lifting and turbulence of the garbage bags, and an approximately simultaneous supply of a second atmospheric air flow to the inside of the container and above the garbage collection zone results in an optimal emptying of the garbage.

Nach einer bevorzugten Ausführungsform der Erfindung kann das erste Ventil während der ersten Evakuierungsstufe geöffnet und wiederholt geschlossen und geöffnet werden, sodass man mit Sicherheit sämtliche oberhalb des Ventils im Müllschacht befindliche Müllbeutel in den Behälter absaugt.According to a preferred embodiment of the invention, the first valve can be opened and repeatedly closed and opened during the first evacuation stage, so that all the garbage bags located above the valve in the refuse shaft are safely sucked into the container.

Nach einer anderen Ausführungsform der Erfindung kann das erste Ventil nach der ersten Evakuierungsstufe während der initialen Luftevakuierung des Behälters geschlossen sein.According to another embodiment of the invention, the first valve can be closed after the first evacuation stage during the initial air evacuation of the container.

Nach einer bevorzugten Ausführungsform der Erfindung kann man während des gänzlichen Entleerungsverlaufes einen Atmosphärenluftstrom in den Behälter einführen - hierdurch werden unerwünschte Materialbeanspuchungen und auch das Entstehen von Schallstössen verhindert, die bei einer momentanen Zufuhr der Atmosphärenluft entstehen, wenn der Behälter luftleer ist. Hierbei kann diese Luftzufuhr auch während des Aufbaus eines Vakuums im Behälter nach und nach erhöht werden.According to a preferred embodiment of the invention, an atmospheric air flow can be introduced into the container during the entire emptying process - this prevents undesirable material stresses and also the occurrence of sound impacts that occur when the atmosphere is supplied at a moment when the container is empty. This air supply can be gradually increased even while a vacuum is being built up in the container.

Diese kontinuierliche Zufuhr von Atmonsphärenluft zum Inneren des Behälters kann dadurch erreicht werden, dass das erste Ventil während des ganzen Entleerungsverfahrens etwas geöffnet ist.This continuous supply of atmospheric air to the interior of the container can be achieved by opening the first valve somewhat during the entire emptying process.

Nach einer alternativen Ausführungsform kann ein weiterer Atmosphärenluftstrom während der dritten Evakuierungsphase in den Behälter eingeführt werden, und zwar dadurch dass das erste Ventil geöffnet ist und/oder dass weitere Luft über eine im Oberteil des Behälters, d.h. oberhalb der Müllsammelzone, vorhandene ventilgesteuerte Öffnung zugeführt wird.According to an alternative embodiment, a further atmospheric air stream can be introduced into the container during the third evacuation phase, namely by the first valve being open and / or by further air being supplied via an in the upper part of the container, i.e. above the waste collection zone, existing valve-controlled opening is fed.

Die Erfindung wird nachstehend an Hand eines in der beiliegender Zeichnung veranschaulichten Ausführungsbeispieles näher erläutet.The invention is explained in more detail below with the aid of an exemplary embodiment illustrated in the accompanying drawing.

Der in der Zeichnung in seinem grundsätzlichen Aufbau gezeigte Müllsammelbehälter wird allgemein mit 1 bezeichnet und ist vorzugsweise in einem vorhandenen Müllsammelraum eines Mehrfamilienhauses angeordnet. Der Müllsanunelbehälter ist über eine Öffnung 2 an einen Müllschacht 3 angeschlossen, wobei die Öffnung durch ein Ventil 4 geregelt wird.The garbage collection container shown in the drawing in its basic structure is generally designated 1 and is preferably arranged in an existing garbage collection room of an apartment building. The refuse container is connected via an opening 2 to a refuse shaft 3, the opening being regulated by a valve 4.

Im Boden des Behälters ist eine Müllentnahmeleitung 5 vorgesehen, die über ein Ventil 6 an eine Sammelkammer eines nicht gezeigten Müllfahrzeuges angeschlossen ist. Diese Sammelkammer kann in bekannter Weise luftleer gemacht werden, so dass die erforderliche Saugwirkung zur Entleerung des Müllsammelbehälters 1 erreicht wird. Unter der Müllsammelzone 7 im Behälter ist eine im Boden des Behälters angeordnete ventilgesteuerte Öffnung 8 zum Einlass eines Atmosphärenluftstromes unterhalb der angesammelten Müllbeutel vorgesehen und schliesslich ist gegebenfalls noch eine weitere ventilgesteuerte Öffnung 9 im oberen Teil des Behälters zwecks Einfuhr eines Sekundär luftstromes oberhalb der Müllsammelzone 7 vorgesehen.A waste removal line 5 is provided in the bottom of the container and is connected via a valve 6 to a collecting chamber of a refuse vehicle, not shown. This collecting chamber can be made empty of air in a known manner, so that the necessary suction effect for emptying the waste collecting container 1 is achieved. Under the garbage collection zone 7 in the container, a valve-controlled opening 8 is provided in the bottom of the container for the inlet of an atmospheric air flow below the accumulated garbage bags and finally there is optionally a further valve-controlled opening 9 in the upper part of the container Container intended for the introduction of a secondary air flow above the waste collection zone 7.

Das erfindungsgemäss vorgeschlagene Verfahren zur Entleerung des Behälters umfasst folgende Stufen:The method according to the invention for emptying the container comprises the following stages:

In einer ersten Evakuierungsstufe sind die Ventile 4 und 6 geöffnet. Hierdurch wird erreicht, dass gegebenenfalls oberhalb des Ventiles 4 im Schacht 3 befindliche Müllbeutel in den Behälter 1 gesogen werden. Um eine garantierte Freigabe des unteren Teils des Schachtes 3 von angestauten Müllbeuteln zu erreichen, kann das Ventil hierbei wiederholt geschlossen und geöffnet werden. Danach wird dieses Ventil zweckmässigerweise zunächst geschlossen, und nach dem Aufbau eines Vakuums im Inneren des Behälters 1 wird das Bodenventil 8 geöffnet, wodurch Atmosphärsluft in den Behälter 1 unter die sich angesammelten Müllbeutel eingeführt wird. Die Müllbeutel werden hierbei vom Boden des Behälters 1 angehoben und in eine gewisse Turbulenz im Behälter versetzt.In a first evacuation stage, valves 4 and 6 are open. This ensures that garbage bags located in the shaft 3 above the valve 4 are sucked into the container 1. In order to achieve guaranteed release of the lower part of the shaft 3 of jammed garbage bags, the valve can be closed and opened repeatedly. Then this valve is expediently first closed, and after a vacuum has been built up inside the container 1, the bottom valve 8 is opened, as a result of which atmospheric air is introduced into the container 1 under the accumulated garbage bags. The garbage bags are lifted from the bottom of the container 1 and set in a certain turbulence in the container.

Um ein schnelles und maximales Entleeren dieser Müllbeutel zu erreichen, wird danach entweder das Ventil 4 oder auch das Ventil 9 geöffnet, so dass ein Sekundärluftstrom in den Behälter eingeführt wird, der mit Sicherheit die Müllbeutel zur Entnahmeleitung 5 transportiert.In order to achieve a quick and maximum emptying of these garbage bags, either the valve 4 or the valve 9 is then opened, so that a secondary air flow is introduced into the container, which safely transports the garbage bags to the removal line 5.

Nach einer alternativen Ausbildung der Erfindung kann das Ventil 4 oder auch der Atmosphärenlufteinlass 8 während des ganzen Entleerungsprozesses etwas geöffnet sein. Hierdurch wird eine momentane Atmosphärenluftzufuhr zum Inneren des Behälters eliminiert, und dadurch werden allzu kräftige Materialbeanspruchungen und auch Schallstösse verhindert.According to an alternative embodiment of the invention, the valve 4 or the atmospheric air inlet 8 can be slightly open during the entire emptying process. This eliminates a momentary supply of atmospheric air to the interior of the container, and this prevents excessive stress on the material and also noise.

Die oben genannten Ventilfunktionen werden zweckmässig automatisch vom Müllfahrzeug gesteuert, nachdem ein notwendiges Docken mit der Entnahmeleitung vorgenommen worden ist. Nach Beendigung des Entleerungsprozesses sind sämtliche Ventile ausser dem Mülleinlassventil geschlossen.The above-mentioned valve functions are appropriately automatically controlled by the garbage truck after a necessary one Docking has been done with the sampling line. After the emptying process has ended, all valves except the waste inlet valve are closed.

Die Erfindung ist jedoch nicht auf die in der Zeichnung gezeigte Ausführungsform beschränkt, sondern kann in verschiedenster Weise im Rahmen der nachfolgenden Ansprüche variiert werden.However, the invention is not limited to the embodiment shown in the drawing, but can be varied in various ways within the scope of the following claims.
