Definitions
- the present invention relates to a device for cleaning container pumps with a pump lance for flowable media, according to the preamble of claim 1.
- Conveyor units are used in numerous areas of trade and industry. In principle, liquids of different viscosities can be conveyed that are to be transferred from one container to another.
- delivery units can be equipped with pump lances and thus protrude into a barrel, for example, the delivery unit taking the liquid contained in the barrel through the pump lance and conveying it on.
- Conveying units are often used in industry for different media, so that it is necessary to return the conveying units to an internal and external cleaning in order to completely remove a first conveyed medium before a conveying unit is used to convey a second medium. This is the only way to ensure that contamination of the conveyed media is effectively avoided.
- the present invention is based on the object of providing a device for cleaning container pumps with a pump lance for flowable media, which can be used very simply and effectively in order to keep the associated expenditure as low as possible on the part of the users.
- a device for cleaning conveying units for flowable media can initially form a fluidic cleaning circuit in which a cleaning agent is pumped in a circle between a cleaning agent tank and the conveying unit to be cleaned.
- the cleaning agent is also a flowable medium which, due to the passage through the conveying unit, reaches wherever the flowable media conveyed during operation of the conveying unit also reaches.
- the cleaning agent can be simple water, but effective substances such as soaps or other chemical, disinfectant or solvent-containing substances can also be added to the water.
- Other hydrocarbon-based cleaning agents such as alcohols, benzenes and the like can also be used or form the basis for a cleaning agent.
- the cleaning agent tank is filled with the cleaning agent and then the circulation in the cleaning circuit thus formed is started.
- the circulation takes place here with the aid of the conveyor unit to be cleaned itself, which conveys the cleaning agent originating from the cleaning agent tank through itself and returns it to the cleaning agent tank.
- This provides the user with an opportunity to clean the conveyor unit by simply hooking it into the cleaning circuit described and operating it.
- the cleaning agent can be exchanged for a rinsing agent which also largely rinses away the substances in the cleaning agent.
- the pump can also be left to stand overnight in the rinsing step in order to remove even intensive dirt.
- a dosing pump has, for example, an inlet and an outlet, which can be connected directly to the detergent tank, so that the dosing pump, as a delivery unit, conveys directly from the detergent tank into the detergent tank.
- the inlet is then connected to an outlet of the detergent tank via an inlet line and the outlet is connected to an inlet of the detergent tank via an outlet line.
- the delivery unit is a container pump with a pump lance.
- the pump lance is inserted directly into the detergent tank, which is designed as a dip tank. Then the tank pump will pump cleaning agent out of the immersion tank and feed it directly via an inlet.
- the immersion container provided for cleaning the container pump is formed separately from the detergent tank.
- the cleaning circuit then provides an immersion container with an upper insertion opening for inserting the pump lance of the container pump.
- the container pump then sucks the detergent out of the immersion container and conveys it back into the detergent tank, from where it can flow back into the immersion container via an inlet line.
- the immersion container can have a taper in its upper region, that is to say around the insertion opening, so that the pumping action becomes stronger in the upper region and the flow caused by the pump flows faster there. This also improves the cleaning effect.
- the immersion container can furthermore have an insertion funnel on its upper insertion opening, which extends upwards and by means of which the positioning of the pump lance of a container pump to be connected to the immersion container is simplified.
- an insertion funnel can possibly catch medium dripping from the conveying unit and let it run into the immersion container, so that no contamination arises around the device.
- a drip guard can also be attached to this insertion funnel, which, for example, has a channel-shaped design and can be releasably connected to the upper edge of the insertion funnel by clamping, plugging, screwing and the like. While the insertion funnel provides a more local drip protection, the drip protection plate can cover the entire way out of a container up to the immersion container and catch any falling drops and introduce them into the insertion funnel.
- the drip protection plate can also be placed on the insertion funnel and the container in which the container pump was previously operated, but in order to ensure that the dripping liquid runs into the insertion funnel, the drip protection plate must be at least horizontal, preferably at an angle between 0 ° and 10 °, be inclined down to the upper edge of the insertion funnel and particularly preferably project from this upper edge in a self-supporting manner.
- a fixing device can therefore be provided in the area of the insertion opening of the immersion container be with which the pump lance and thus the container pump connected to the pump lance are fixed relative to the immersion tank.
- Such a fixing device can be formed from a plurality of clamping screws distributed over the circumference of the outer wall of the immersion container, which can be screwed through the outer wall with the aid of a thread cut into or placed in front of the outer wall towards the center of the insertion opening. You then hit the pump lance and fix it from several sides until the pump lance is immobile.
- the clamping screws can be provided with terminal handwheels so that they can be fixed with the bare hand, i.e. without tools.
- An essential aspect of the invention is a cleaning of container pumps with a pump lance from the inside, in that the cleaning agent is pumped through the container pumps with a pump lance. According to the invention, this also cleans an outer area of the pump lance, namely the area of the pump lance that projects into the medium to be pumped.
- a plurality of feed lines are assigned to the outer wall of the immersion tank in the area of the insertion opening, via which cleaning agents are injected into the immersion tank from the immersion tank or from the cleaning agent tank.
- a sleeve chamber is formed around the insertion opening, on the inner wall of which one or more, preferably uniformly over the inner circumference of the inner wall of the sleeve chamber, have inlet openings in the direction of the pump lance.
- auxiliary pump may also be useful to assign an auxiliary pump to the inlet line, which is connected to the cuff chamber, since otherwise the container pump cannot pump a cleaning agent into the circuit when it is first introduced. If necessary, the auxiliary pump can support the delivery unit to be cleaned or only work alternately with it.
- the inlet line or, alternatively or additionally, the outlet line has a floor outlet, which is preferably formed at a geodetically lowest point and allows the cleaning circuit to be emptied due to gravity.
- a drain valve prevents the accidental loss of cleaning agent and can therefore switch back and forth between an open and a closed position.
- a filter arrangement can also be assigned to the floor drain, with the aid of which substances of the cleaning agent can be separated and / or neutralized. This prevents pollutants contained in the cleaning agent from escaping and being an environmental toxin.
- a heating element can also be assigned to the cleaning circuit.
- a heating element which can be configured as a continuous-flow heater or the like, the temperature of the cleaning agent can be increased in order to also use thermal reaction forces for an improved cleaning effect.
- the cleaning agent is continuously pumped in a circle, so that there is almost no change in the amount of cleaning agent during a cleaning process.
- the detergent tank or, if applicable, the immersion container can have a filling opening at which a filling line to a detergent source such as a water pipe or a detergent container.
- Additives that have an effect on cleaning can preferably be added to the cleaning agent, for example with the aid of a metering pump assigned to the filling line, preferably a proportional metering.
- the entire cleaning cycle works in a very simple arrangement, initially with a single conveyor unit. However, it is also possible to connect a plurality of conveying units in series in terms of flow, so that the cleaning agent flows through the individual conveying units one after the other. In this case, however, only one of the conveying units should be actively operated, while the other conveying units are at most driven by the flowing cleaning agent. If several conveying units were operated at the same time, a pressure could build up between several conveying units with different delivery rates, which could damage the conveying units.
- the cleaning circuit with its elements is arranged as a mobile construction on a transport vehicle, such as a hand truck.
- a transport vehicle such as a hand truck.
- Figure 1 shows a handcart 26 which is mounted on wheels and is therefore designed to be mobile.
- This handcart 26 is set up in the immediate vicinity of a barrel 25, from which a delivery unit 1 with a pump lance 7 has just been removed and inserted into an immersion container 8.
- the conveying unit 1 was previously used in the barrel 25 as a container pump in order to convey the contents of the barrel 25 and to carry out its determination. Now that the delivery unit 1 is no longer required in the barrel 25, the delivery unit 1 with its pump lance 7 is pulled out of the barrel 25 and introduced into the immersion container 8 for cleaning.
- the immersion container 8 has an insertion funnel 10.
- a drip protection plate 24 is releasably attached to the edge of the insertion funnel by jamming or screwing, so that the pump lance 7 leaves no impurities when it is pulled out of the barrel 25 and brought into the immersion container 8.
- the pump lance 7 is always above the barrel 25, the trough-shaped drip protection plate 24 or the insertion funnel 10 until it passes through an insertion opening 9 in the Center of the insertion funnel 10 was introduced into the interior of the immersion container 8.
- a detergent tank 4 which sprays detergent onto the pump lance via an auxiliary pump 16 through a sleeve ring 14 of the immersion container 8, as will be explained later Figure 2 described.
- the detergent tank 4 is also connected to the immersion tank 8 via an inlet / outlet line 5, 6 close to the floor and to an outlet of the delivery unit 1 via an outlet line 6.
- the cleaning agent held in the cleaning agent tank 4 is then introduced during operation of the arrangement described from the cleaning agent tank 4 via the feed lines 5 into the immersion tank 8 and there clean the pump lance 7 from the outside.
- the conveyor unit 1 is operated for this purpose, so that detergent contained in the immersion container 8, for example water with a cleaning additive, is sucked in at the free end of the pump lance 7 and pumped through the pump lance 7 and the conveyor unit 1 back into the detergent tank. Due to the flow through the conveyor unit 1 and the flushing of the immersed parts, the conveyor unit 1 is cleaned from the inside and from the outside.
- detergent contained in the immersion container 8 for example water with a cleaning additive
- an additional tank 22 is also arranged on the trolley 26, in which the cleaning additive is kept.
- a proportional metering 21 which is also connected to a cleaning agent source 23, for example a water pipe or another tank.
- the proportional dosing ensures that an exact mixture of the desired cleaning agent is available and that the ratio between cleaning agent and cleaning additive remains the same even in the case of a pure refill.
- a floor drain 17 is provided, which is arranged in an inlet / outlet pipe near the floor between the cleaning agent tank 4 and the immersion container 8.
- the drain valve 18 By opening the drain valve 18, both the detergent tank 4 and the immersion container 8 can be completely emptied due to the force of gravity, which, depending on the application, the medium last conveyed and the detergent and cleaning additives used, can take place in a collecting container or in the sewage system.
- FIG 2 shows as a detail the Figure 1 the area of the insertion opening 9 of the immersion container 8. This is assigned a cuff ring 14 which surrounds the insertion opening 9.
- cleaning agent is conveyed from the cleaning agent tank 4 during the introduction of the pump lance 7 of the delivery unit to be cleaned into the immersion container 8, which first fills a cavity in the sleeve ring 14 and then via inlet openings 15 on the inside of the sleeve ring 14 onto the pump lance 7 sprays.
- an external cleaning of the pump lance 7 into the immersion container 8 already takes place before an internal cleaning is also added by starting up the delivery unit 1.
- the pump lance is clamped with the aid of clamping screws 13, which are arranged on a fixing device 12 and distributed over the circumference of the neck of the immersion container, so that when the conveyor unit 1 is operating, it does not swing up to strong movements, but is held securely.
- Figure 3 finally shows a schematic arrangement of the elements of the cleaning circuit for the case of simultaneous cleaning of three conveying units 1, 2 and 3 to be cleaned. These are connected in series in terms of flow technology, so that firstly, the conveying unit 1, then the conveying unit 2 and finally the conveying unit 3 passes through before it is conveyed back to the detergent tank 4 via an outlet line 6. Only the first is an active conveyor unit 1, while the other two are passive conveyor units 2 and 3, which are driven by the active conveyor unit 1.
- a cleaning agent source 23 and an additional tank 22 are supplied with a cleaning additive, these components are mixed with the cleaning agent used and the cleaning agent tank 4 is thus filled for the first time.
- the drain valve 18 is opened and the dirty cleaning agent is cleaned via a filter arrangement 19 and removed from the system via a floor drain.
- a device for cleaning conveying units for flowable media is thus described above, with which simple and effective cleaning is ensured by circulating cleaning agent through one or more conveying units.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Reinigung von Behälterpumpen mit einer Pumpenlanze für fließfähige Medien, entsprechend dem Oberbegriff des Anspruchs 1.The present invention relates to a device for cleaning container pumps with a pump lance for flowable media, according to the preamble of
Eine derartige Lösung ist bereits aus der
Eine weitere Vorrichtung zum Reinigen anderer Förderaggregate ist aus der
Häufig werden Förderaggregate in der Industrie für unterschiedliche Medien eingesetzt, so dass es erforderlich ist, die Förderaggregate einer inwendigen und auswendigen Reinigung zurückzuführen, um ein erstes gefördertes Medium vollständig zu entfernen, bevor ein Förderaggregat zur Förderung eines zweiten Mediums verwendet wird. Nur so kann gewährleistet werden, dass eine Verunreinigung der geförderten Medien wirkungsvoll vermieden wird.Conveying units are often used in industry for different media, so that it is necessary to return the conveying units to an internal and external cleaning in order to completely remove a first conveyed medium before a conveying unit is used to convey a second medium. This is the only way to ensure that contamination of the conveyed media is effectively avoided.
In aller Regel stellt jedoch die sorgfältige Reinigung eines Förderaggregats, insbesondere auch einer Pumpenlanze, einen aufwändigen Arbeitsschritt dar, der von Benutzungspersonal häufig vergessen oder eingespart wird. Neben Verunreinigungen der zu fördernden Medien kommt es dabei auch zu Verschmutzungen und auf Dauer zu Beschädigungen an den Förderaggregaten, deren Behebung dann noch wesentlich aufwändiger und kostenintensiver wird und zudem für einen längeren Ausfall des Förderaggregats sorgt.As a rule, however, the careful cleaning of a delivery unit, in particular also a pump lance, represents a complex work step that is often forgotten or saved by user personnel. In addition to contamination of the media to be conveyed, this also leads to contamination and, in the long term, damage to the conveying units, the remedy of which then becomes much more complex and cost-intensive and also ensures a longer failure of the conveying unit.
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Vorrichtung zur Reinigung von Behälterpumpen mit einer Pumpenlanze für fließfähige Medien zu schaffen, welche sehr einfach und effektiv eingesetzt werden kann, um die hiermit einhergehenden Aufwände aufseiten der Benutzer möglichst gering zu halten.Against this background, the present invention is based on the object of providing a device for cleaning container pumps with a pump lance for flowable media, which can be used very simply and effectively in order to keep the associated expenditure as low as possible on the part of the users.
Dies gelingt durch eine Vorrichtung zur Reinigung von Behälterpumpen mit einer Pumpenlanze für fließfähige Medien gemäß Merkmalen des Anspruchs 1. Weitere, sinnvolle Ausgestaltungen einer derartigen Vorrichtung können den Unteransprüchen entnommen werden.This is achieved by a device for cleaning container pumps with a pump lance for flowable media according to the features of
Eine Vorrichtung zur Reinigung von Förderaggregaten für fließfähige Medien kann zunächst einen strömungstechnischen Reinigungskreis ausbilden, in welchem ein Reinigungsmittel zwischen einem Reinigungsmitteltank und dem zu reinigenden Förderaggregat im Kreis gepumpt wird. Auch bei dem Reinigungsmittel handelt es sich um ein fließfähiges Medium, das aufgrund des Durchlaufens durch das Förderaggregat überall dorthin gelangt, wo auch die im Betrieb des Förderaggregats geförderten fließfähigen Medien hingelangen. In einem einfachen Fall kann es sich bei dem Reinigungsmittel um einfaches Wasser handeln, dem Wasser können aber auch wirksame Substanzen wie Seifen oder andere chemische, desinfizierende oder lösemittelhaltige Substanzen beigemischt werden. Auch können andere Reinigungsmittel auf Kohlenwasserstoffbasis wie Alkohole, Benzole und dergleichen mehr eingesetzt werden oder die Basis für ein Reinigungsmittel bilden.A device for cleaning conveying units for flowable media can initially form a fluidic cleaning circuit in which a cleaning agent is pumped in a circle between a cleaning agent tank and the conveying unit to be cleaned. The cleaning agent is also a flowable medium which, due to the passage through the conveying unit, reaches wherever the flowable media conveyed during operation of the conveying unit also reaches. In a simple case, the cleaning agent can be simple water, but effective substances such as soaps or other chemical, disinfectant or solvent-containing substances can also be added to the water. Other hydrocarbon-based cleaning agents such as alcohols, benzenes and the like can also be used or form the basis for a cleaning agent.
Zunächst wird hierbei der Reinigungsmitteltank mit dem Reinigungsmittel befüllt und dann die Umwälzung im so gebildeten Reinigungskreis begonnen. Die Umwälzung erfolgt hierbei mithilfe des zu reinigenden Förderaggregats selbst, welches das aus dem Reinigungsmitteltank stammende Reinigungsmittel durch sich selbst hindurchfördert und wieder in den Reinigungsmitteltank zurückleitet. Hierdurch ergibt sich für den Benutzer eine Möglichkeit, das Förderaggregat zu reinigen, indem es einfach in den beschriebenen Reinigungskreis eingehängt und betrieben wird. Ergänzend kann nach einem Spülvorgang das Reinigungsmittel noch gegen ein Mittel zum Nachspülen ausgetauscht werden, welches die Substanzen des Reinigungsmittels ebenfalls weitgehend wegspült. Auch ist es möglich, das Förderaggregat mit dem Reinigungsmittel darin etwa über Nacht, zwischen dem Spülschritt und dem Nachspülschritt stehen zu lassen, so dass die Substanzen des Reinigungsmittels wirken können. Auch kann die Pumpe im Spülschritt über Nacht stehen gelassen werden, um auch intensive Verschmutzungen zu beseitigen.First the cleaning agent tank is filled with the cleaning agent and then the circulation in the cleaning circuit thus formed is started. The circulation takes place here with the aid of the conveyor unit to be cleaned itself, which conveys the cleaning agent originating from the cleaning agent tank through itself and returns it to the cleaning agent tank. This provides the user with an opportunity to clean the conveyor unit by simply hooking it into the cleaning circuit described and operating it. In addition, after a rinsing process, the cleaning agent can be exchanged for a rinsing agent which also largely rinses away the substances in the cleaning agent. It is also possible to dispose of the conveying unit with the cleaning agent in it Leave overnight, between the rinsing step and the rinsing step, so that the substances in the detergent can work. The pump can also be left to stand overnight in the rinsing step in order to remove even intensive dirt.
In jedem Fall entfallen hierdurch aufwändige Reinigungsschritte, um die Förderaggregate zu reinigen, so dass eine sorgfältige Reinigung für den Benutzer attraktiver und einfacher, sowie effektiver wird.In any case, this eliminates the need for time-consuming cleaning steps to clean the conveyor units, so that careful cleaning becomes more attractive, simple and effective for the user.
Der Aufbau eines solchen Reinigungskreises hängt etwas von den zu reinigenden Förderaggregaten ab. Eine Dosierpumpe hat beispielsweise einen Zulauf und einen Ablauf, welche direkt mit dem Reinigungsmitteltank verbunden werden können, so dass die Dosierpumpe als Förderaggregat direkt aus dem Reinigungsmitteltank in den Reinigungsmitteltank fördert. Der Zulauf ist dann über eine Zulaufleitung mit einem Ablauf des Reinigungsmitteltanks und der Ablauf über eine Ablaufleitung mit einem Zulauf des Reinigungsmitteltanks verbunden.The structure of such a cleaning circuit depends somewhat on the conveyor units to be cleaned. A dosing pump has, for example, an inlet and an outlet, which can be connected directly to the detergent tank, so that the dosing pump, as a delivery unit, conveys directly from the detergent tank into the detergent tank. The inlet is then connected to an outlet of the detergent tank via an inlet line and the outlet is connected to an inlet of the detergent tank via an outlet line.
Erfindungsgemäß handelt es sich bei dem Förderaggregat um eine Behälterpumpe mit einer Pumpenlanze. D.h. die Pumpenlanze wird direkt in den Reinigungsmitteltank eingeführt, der als Tauchbehälter ausgestaltet ist. Dann wird die Behälterpumpe Reinigungsmittel aus dem Tauchbehälter herausfördern und ihm wieder direkt über einen Zulauf zuführen.According to the invention, the delivery unit is a container pump with a pump lance. I.e. the pump lance is inserted directly into the detergent tank, which is designed as a dip tank. Then the tank pump will pump cleaning agent out of the immersion tank and feed it directly via an inlet.
Erfindungsgemäß wird der für die Reinigung der Behälterpumpe vorgesehene Tauchbehälter von dem Reinigungsmitteltank separat gebildet. Dann sieht der Reinigungskreis einen Tauchbehälter mit einer oberseitigen Einführöffnung zum Einführen der Pumpenlanze der Behälterpumpe vor. Die Behälterpumpe saugt dann das Reinigungsmittel aus dem Tauchbehälter an und fördert es zurück in den Reinigungsmitteltank, von wo es über eine Zulaufleitung zurück in den Tauchbehälter strömen kann.According to the invention, the immersion container provided for cleaning the container pump is formed separately from the detergent tank. The cleaning circuit then provides an immersion container with an upper insertion opening for inserting the pump lance of the container pump. The container pump then sucks the detergent out of the immersion container and conveys it back into the detergent tank, from where it can flow back into the immersion container via an inlet line.
Mit einigem Vorteil kann der Tauchbehälter in seinem oberen Bereich, also um die Einführöffnung herum, eine Verjüngung aufweisen, so dass die Pumpwirkung im oberen Bereich stärker wird und dort die von der Pumpe verursachte Strömung schneller fließt. Dies verbessert zusätzlich die Reinigungswirkung.With some advantage, the immersion container can have a taper in its upper region, that is to say around the insertion opening, so that the pumping action becomes stronger in the upper region and the flow caused by the pump flows faster there. This also improves the cleaning effect.
Der Tauchbehälter kann ferner an seiner oberseitigen Einführöffnung einen Einführtrichter aufweisen, der sich nach oben erweitert und über den eine Positionierung der Pumpenlanze einer mit dem Tauchbehälter zu verbindenden Behälterpumpe vereinfacht wird. Zudem kann ein solcher Einführtrichter eventuell von dem Förderaggregat abtropfendes Medium auffangen und in den Tauchbehälter einlaufen lassen, so dass keine Verunreinigungen um die Vorrichtung herum entstehen.The immersion container can furthermore have an insertion funnel on its upper insertion opening, which extends upwards and by means of which the positioning of the pump lance of a container pump to be connected to the immersion container is simplified. In addition, such an insertion funnel can possibly catch medium dripping from the conveying unit and let it run into the immersion container, so that no contamination arises around the device.
An diesen Einführtrichter kann ferner ein Tropfschutzblech angebracht sein, welches beispielsweise rinnenförmig gestaltet und durch Klemmen, Stecken, Schrauben und dergleichen lösbar mit der Oberkante des Einführtrichters verbunden werden kann. Während der Einführtrichter einen eher lokalen Tropfschutz bewirkt, kann das Tropfschutzblech den vollständigen Weg aus einem Behälter heraus bis zu dem Tauchbehälter abdecken und eventuell abfallende Tropfen auffangen und in den Einführtrichter einleiten. Hierzu kann das Tropfschutzblech zwar auch auf dem Einführtrichter und dem Behälter, in dem die Behälterpumpe zuvor betrieben wurde, aufgelegt sein, um jedoch ein Einlaufen der abtropfenden Flüssigkeit auf in den Einführtrichter zu gewährleisten muss der Tropfschutzblech wenigstens waagrecht, vorzugsweise in einem Winkel zwischen 0° und 10°, zu der Oberkante des Einführtrichters herab geneigt sein und besonders bevorzugt von dieser Oberkante aus freitragend abstehen.A drip guard can also be attached to this insertion funnel, which, for example, has a channel-shaped design and can be releasably connected to the upper edge of the insertion funnel by clamping, plugging, screwing and the like. While the insertion funnel provides a more local drip protection, the drip protection plate can cover the entire way out of a container up to the immersion container and catch any falling drops and introduce them into the insertion funnel. For this purpose, the drip protection plate can also be placed on the insertion funnel and the container in which the container pump was previously operated, but in order to ensure that the dripping liquid runs into the insertion funnel, the drip protection plate must be at least horizontal, preferably at an angle between 0 ° and 10 °, be inclined down to the upper edge of the insertion funnel and particularly preferably project from this upper edge in a self-supporting manner.
Nach dem Einführen der Pumpenlanze mit der daran befestigten Behälterpumpe in den Tauchbehälter wird die Behälterpumpe zur Reinigung eingeschaltet. Hierdurch können Schwingungen entstehen, die für Lärm und eine unsichere Lagerung der Behälterpumpe in dem Tauchbehälter sorgen. Daher kann im Bereich der Einführöffnung des Tauchbehälters eine Fixiereinrichtung vorgesehen sein, mit welcher die Pumpenlanze und damit die mit der Pumpenlanze verbundene Behälterpumpe gegenüber dem Tauchbehälter festgelegt werden.After inserting the pump lance with the attached tank pump into the immersion tank, the tank pump is switched on for cleaning. This can cause vibrations that cause noise and unsafe storage of the tank pump in the immersion tank. A fixing device can therefore be provided in the area of the insertion opening of the immersion container be with which the pump lance and thus the container pump connected to the pump lance are fixed relative to the immersion tank.
Eine solche Fixiereinrichtung kann aus einer Mehrzahl von über den Umfang der Außenwand des Tauchbehälters verteilten Klemmschrauben gebildet sein, welche durch die Außenwand hindurch mithilfe jeweils eines in die Außenwand eingeschnittenen oder dieser vorgesetzten Gewindes auf die Mitte der Einführöffnung zu geschraubt werden können. Sie treffen dann auf die Pumpenlanze und fixieren sie von mehreren Seiten, bis die Pumpenlanze unbeweglich gehalten ist. Die Klemmschrauben können mit endständigen Handrädern versehen sein, um eine Fixierung mit der bloßen Hand, also werkzeugfrei, erledigen zu können.Such a fixing device can be formed from a plurality of clamping screws distributed over the circumference of the outer wall of the immersion container, which can be screwed through the outer wall with the aid of a thread cut into or placed in front of the outer wall towards the center of the insertion opening. You then hit the pump lance and fix it from several sides until the pump lance is immobile. The clamping screws can be provided with terminal handwheels so that they can be fixed with the bare hand, i.e. without tools.
Wesentlicher Aspekt der Erfindung ist eine Reinigung von Behälterpumpen mit einer Pumpenlanze von der Innenseite, indem das Reinigungsmittel durch die Behälterpumpen mit einer Pumpenlanze hindurchgepumpt wird. Erfindungsgemäß wird hierdurch auch ein äußerlicher Bereich der Pumpenlanze gereinigt, nämlich der Bereich der Pumpenlanze, der in das zu fördernde Medium hineinragt. Um eine äußerliche Reinigung zu bewirken, ist erfindungsgemäß der Außenwand des Tauchbehälters im Bereich der Einführöffnung eine Mehrzahl von Zulaufleitungen zugeordnet, über welche Reinigungsmittel aus dem Tauchbehälter oder aus dem Reinigungsmitteltank in den Tauchbehälter eingespritzt wird. Im Moment des Eintauchens der Pumpenlanze wird diese dabei angespritzt und so äußerlich von Schmutz befreit während sie in den Tauchbehälter eingeführt wird.An essential aspect of the invention is a cleaning of container pumps with a pump lance from the inside, in that the cleaning agent is pumped through the container pumps with a pump lance. According to the invention, this also cleans an outer area of the pump lance, namely the area of the pump lance that projects into the medium to be pumped. In order to effect external cleaning, according to the invention, a plurality of feed lines are assigned to the outer wall of the immersion tank in the area of the insertion opening, via which cleaning agents are injected into the immersion tank from the immersion tank or from the cleaning agent tank. When the pump lance is immersed, it is injected and externally freed of dirt while it is being inserted into the immersion tank.
Erfindungsgemäß ist um die Einführöffnung herum eine Manschettenkammer gebildet, an deren Innenwand eine oder mehrere, vorzugsweise gleichmäßig über den Innenumfang der Innenwand der Manschettenkammer, Zulauföffnungen in Richtung der Pumpenlanze weisen. Durch eine Druckbeaufschlagung der Manschettenkammer kann das Reinigungsmittel den Druck über die Zulauföffnungen abbauen, über welche das Reinigungsmittel in das Innere des Rohrs eingespritzt wird.According to the invention, a sleeve chamber is formed around the insertion opening, on the inner wall of which one or more, preferably uniformly over the inner circumference of the inner wall of the sleeve chamber, have inlet openings in the direction of the pump lance. By pressurizing the cuff chamber, the cleaning agent can release the pressure through the inlet openings dismantle, via which the cleaning agent is injected into the interior of the pipe.
Weiter kann es sinnvoll sein, der Zulaufleitung, welche mit der Manschettenkammer verbunden ist, eine Hilfspumpe zuzuordnen, da ansonsten die Behälterpumpe im ersten Moment ihrer Einführung noch kein Reinigungsmittel im Kreis pumpen kann. Gegebenenfalls kann die Hilfspumpe das zu reinigende Förderaggregat unterstützen oder nur im Wechsel mit diesem arbeiten.It may also be useful to assign an auxiliary pump to the inlet line, which is connected to the cuff chamber, since otherwise the container pump cannot pump a cleaning agent into the circuit when it is first introduced. If necessary, the auxiliary pump can support the delivery unit to be cleaned or only work alternately with it.
Im Bodenbereich weist die Zulaufleitung oder alternativ oder zusätzlich die Ablaufleitung einen Bodenablauf auf, welcher vorzugsweise in einem geodätisch tiefsten Punkt gebildet ist und eine Entleerung des Reinigungskreises aufgrund der Schwerkraft erlaubt. Ein Ablaufventil verhindert hierbei das unbeabsichtigte Verlieren von Reinigungsmittel und kann daher zwischen einer Offen- und einer Geschlossenstellung hin und her wechseln.In the floor area, the inlet line or, alternatively or additionally, the outlet line has a floor outlet, which is preferably formed at a geodetically lowest point and allows the cleaning circuit to be emptied due to gravity. A drain valve prevents the accidental loss of cleaning agent and can therefore switch back and forth between an open and a closed position.
Dem Bodenablauf kann ergänzend eine Filteranordnung zugeordnet sein, mit deren Hilfe Substanzen des Reinigungsmittels abgeschieden und/oder neutralisiert werden kann. Es wird so verhindert, dass in dem Reinigungsmittel enthaltene Schadstoffe austreten und ein Umweltgift darstellen.A filter arrangement can also be assigned to the floor drain, with the aid of which substances of the cleaning agent can be separated and / or neutralized. This prevents pollutants contained in the cleaning agent from escaping and being an environmental toxin.
Dem Reinigungskreis kann ferner ein Heizelement zugeordnet sein. Mithilfe eines solchen Heizelements, welches etwa als Durchlauferhitzer oder dergleichen ausgestaltet sein kann, kann die Temperatur des Reinigungsmittels erhöht werden, um auch thermische Reaktionskräfte für eine verbesserte Reinigungswirkung zum Einsatz zu bringen.A heating element can also be assigned to the cleaning circuit. With the aid of such a heating element, which can be configured as a continuous-flow heater or the like, the temperature of the cleaning agent can be increased in order to also use thermal reaction forces for an improved cleaning effect.
Während des Betriebs wird das Reinigungsmittel kontinuierlich im Kreis gepumpt, so dass näherungsweise keine Veränderung der Menge an Reinigungsmittel während eines Reinigungsvorgangs erfolgt. Für eine Erstbefüllung kann jedoch der Reinigungsmitteltank oder gegebenenfalls der Tauchbehälter eine Befüllöffnung aufweisen, an welcher eine Befüllleitung an eine Reinigungsmittelquelle wie etwa eine Wasserleitung oder einen Reinigungsmittelbehälter, angeschlossen werden kann. Dem Reinigungsmittel kann dabei vorzugsweise zusätzlich, etwa mithilfe einer der Befüllleitung zugeordneten Dosierpumpe, vorzugsweise einer Proportionaldosierung, reinigungswirksame Zusatzstoffe zudosiert werden.During operation, the cleaning agent is continuously pumped in a circle, so that there is almost no change in the amount of cleaning agent during a cleaning process. For an initial filling, however, the detergent tank or, if applicable, the immersion container can have a filling opening at which a filling line to a detergent source such as a water pipe or a detergent container. Additives that have an effect on cleaning can preferably be added to the cleaning agent, for example with the aid of a metering pump assigned to the filling line, preferably a proportional metering.
Der gesamte Reinigungskreis funktioniert in einer einfachsten Anordnung zunächst mit einem einzelnen Förderaggregat. Jedoch ist es auch möglich, mehrere Förderaggregate strömungstechnisch hintereinander zu schalten, so dass das Reinigungsmittel die einzelnen Förderaggregate nacheinander durchfließt. In diesem Fall sollte allerdings lediglich eines der Förderaggregate aktiv betrieben werden, während die anderen Förderaggregate allenfalls von dem strömenden Reinigungsmittel getrieben werden. Würden mehrere Förderaggregate gleichzeitig betrieben werden, so könnte sich zwischen mehreren Förderaggregaten unterschiedlicher Förderleistung ein Druck aufbauen, der die Förderaggregate beschädigen könnte.The entire cleaning cycle works in a very simple arrangement, initially with a single conveyor unit. However, it is also possible to connect a plurality of conveying units in series in terms of flow, so that the cleaning agent flows through the individual conveying units one after the other. In this case, however, only one of the conveying units should be actively operated, while the other conveying units are at most driven by the flowing cleaning agent. If several conveying units were operated at the same time, a pressure could build up between several conveying units with different delivery rates, which could damage the conveying units.
Schließlich stellt es eine besonders bevorzugte Ausgestaltung dar, wenn der Reinigungskreis mit seinen Elementen als mobile Konstruktion auf einem Transportfahrzeug angeordnet ist, wie etwa einem Handwagen. So kann die erfindungsgemäße Vorrichtung stets an den Ort verbracht werden, an dem Förderaggregate zu reinigen sind und es ist nicht erforderlich, die mitunter stark verschmutzten Förderaggregate an einen bestimmten Ort zu verbringen und damit die Umgebung ebenfalls zu verschmutzen oder einen großen Aufwand für eine Verpackung oder gar eine Vorreinigung erbringen zu müssen.Finally, it is a particularly preferred embodiment if the cleaning circuit with its elements is arranged as a mobile construction on a transport vehicle, such as a hand truck. Thus, the device according to the invention can always be brought to the place where the conveyor units are to be cleaned and it is not necessary to bring the sometimes heavily soiled conveyor units to a specific location and thus also to pollute the environment or a great deal of effort for packaging or even have to do a pre-cleaning.
Die vorstehend beschriebene Erfindung wird im Folgenden anhand eines Ausführungsbeispiels näher erläutert.The invention described above is explained in more detail below using an exemplary embodiment.

Damit die Pumpenlanze 7 des Förderaggregats 1 leichter in den Tauchbehälter 8 eingeführt werden kann, weist der Tauchbehälter 8 einen Einführtrichter 10 auf. An diesem Einführtrichter 10 ist ein Tropfschutzblech 24 durch Verklemmen oder Verschrauben lösbar am Rand des Einführtrichters befestigt, so dass die Pumpenlanze 7 beim Herausziehen aus dem Fass 25 und Verbringen in den Tauchbehälter 8 keine Verunreinigungen hinterlässt. Die Pumpenlanze 7 befindet sich immer über dem Fass 25, dem rinnenförmig gebildeten Tropfschutzblech 24 oder dem Einführtrichter 10, bis sie durch eine Einführöffnung 9 in der Mitte des Einführtrichters 10 in das Innere des Tauchbehälters 8 eingebracht wurde.So that the

Für eine Erstbefüllung des Reinigungskreises ist auf dem Handwagen 26 ferner ein Zusatztank 22 angeordnet, in welchem der Reinigungszusatz vorgehalten wird. Mit diesem verbunden ist eine Proportionaldosierung 21, welche ebenfalls mit einer Reinigungsmittelquelle 23, beispielsweise einer Wasserleitung oder einem weiteren Tank, verbunden ist. Die Proportionaldosierung sorgt dafür, dass eine exakte Mischung des gewünschten Reinigungsmittels zur Verfügung steht und auch im Fall einer reinen Nachfüllung das Verhältnis zwischen Reinigungsmittel und Reinigungszusatz gleich bleibt.For an initial filling of the cleaning circuit, an
Zur Entleerung des Reinigungskreises ist ein Bodenablauf 17 vorgesehen, welcher in einem Bodennahen Zulauf-/Ablaufrohr zwischen dem Reinigungsmitteltank 4 und dem Tauchbehälter 8 angeordnet ist. Durch ein Öffnen des Ablaufventils 18 können aufgrund der Schwerkraft sowohl der Reinigungsmitteltank 4 als auch der Tauchbehälter 8 vollständig entleert werden, was je nach Anwendungsfall, zuletzt gefördertem Medium und verwendetem Reinigungsmittel und Reinigungszusätzen in einen Auffangbehälter oder in die Kanalisation erfolgen kann.To drain the cleaning circuit, a
