- the filter can be used considerably longer to effect a corresponding cleaning when drinking water is removed before the filter may also have to be cleaned mechanically or in some other way or, if necessary, replaced.
- the device according to the invention allows the water supply to be adapted to these different needs and additionally solves the problem of counteracting contamination of the filter for the drinking water supply for as long as possible, or automatically cleaning the filter when industrial water is withdrawn.

- the filter can be designed as a filter candle and arranged in the housing and the inflow of the process water can lead to the outside of this filter and the outflow of the Drinking water can be connected to the inside of the filter.
- a shut-off valve or the like can be provided at least at the second tap, in particular at both taps.
- a shut-off valve or the like With regard to the flow resistance of the filter, it would be sufficient if a shut-off valve or the like were present at the tap of the process water, because when this valve was opened, the raw water could be removed as process water while avoiding the flow resistance of the filter. It is particularly favorable, however, if a shut-off valve or the like openable closure is provided at each of the two tapping points, so that a possible only slight penetration of raw water into the filter is avoided when used water is withdrawn. Pollution from the outside is also prevented by the shut-off valve. If only one shut-off valve or closure at the second tap is used, water leakage from the first tap can be avoided by switching off or shutting off the aforementioned pump when the shut-off valve or the closure of the second tap is closed.
- the pump can be arranged in the feed line to the housing containing the filter. It can thus be arranged as close as possible to the extraction point for the raw water and at least predominantly designed to act as a pressure pump.
- the pump can also be a submersible pump connected to the filter via a hose or the like containing housing is connected.
- the pump can in any case be a pressure pump, so that the raw water can also be pumped from a relatively large depth, for example from relatively deep wells.
- a shut-off valve, slide or similar closure can be arranged in the supply line between the pump and the housing.
- the device and the area of the filter can be separated from the supply line, especially when not in use.
- a return of water in the housing can also be avoided. This can also be advantageous for repairs to the pump.
- the pump can have an electromotive drive and, in particular, one or more photovoltaic or solar modules can be provided as current sources.
- the device is particularly suitable for use in remote areas that have no power supply but sufficient sunshine.
- power generation with a wind turbine, internal combustion engine or the like would also be possible.
- the solar modules can be connected to one or more accumulators for storing electrical energy.
- the device can also be operated for a certain time when a power supply is not possible, for example existing solar modules do not generate electricity due to the lack of sunshine.
- the housing for the filter, the accumulators and the solar modules can be attached to a common frame or housing, so that a mobile and transportable device can result, which of course can also be permanently installed is.
- the filter can be installed interchangeably. Such a replacement of the filter is only necessary after a very long time, since the filter cleans the filter automatically again and again when it is removed as process water by the incoming raw water, but the performance of the filter can nevertheless deteriorate to such an extent over a long period of use that a Exchange is appropriate.
- An expedient embodiment of the device can consist in that a positive displacement, centrifugal or vane pump and a pressure relief valve arranged in the vicinity thereof are provided for generating a constant water pressure.
- a positive displacement, centrifugal or vane pump and a pressure relief valve arranged in the vicinity thereof are provided for generating a constant water pressure.
- a filter in particular a fine filter, can be arranged on the suction side of the pump.
- constituents contained in the raw water can already be retained to a large extent, so that the microfilter arranged in the device is less loaded and is available for a correspondingly longer time due to the automatic cleaning.
- a device of the type mentioned at the outset results which can be used in rural areas and in particular in developing countries and which has a compact structure made up of water pipes and mains electricity.
- dependent device for drinking and industrial water supply For example, with a well depth of 20 mtr. and a typical solar radiation offer for North Africa about 200 ltr. Drinking water and 1,000 l. Process water can be made available.
- a ceramic microfilter as a disinfection unit has the advantage that, on the one hand, the chemical nature of the drinking water and thus also its smell and taste are not changed, but on the other hand a sufficiently safe disinfection is achieved. Due to the physical mode of operation of the sieve filter - essentially a sieve effect - the device is particularly effective with regard to larger pathogens such as parasites and those that preferentially accumulate in suspended water.
- the disinfectant effect of the filter does not need to be checked using chemical analysis or (complicated) electronic monitoring.
- the only auxiliary means is a sliding void with which the remaining thickness of the ceramic tinsel is checked after appropriate mechanical treatment and on the basis of which it can be decided when the filter must be replaced due to a reduction in the disinfectant layer. Thus, even unskilled personnel can operate and maintain this device.
- the filter Due to the fact that the drinking water is pushed through the filter, but that industrial water is led past the filter, the filter is automatically cleaned each time industrial water is withdrawn. This reduces the need for manual cleaning and consequently increases the service life of the filter considerably. It is also to be regarded as advantageous that no additional water and no treated water are required for this cleaning. The supplied water can therefore be used 100 percent.
- Operation is extremely simple because a single switch is all that is required to start up the device by switching on the pump. The user then only needs to open the correct tap to tap either drinking water or process water. If he taps both taps in public, he receives hot water due to the flow resistance of the filter. If he does not publicize any of the taps, the water is returned to the water source via the pressure relief valve already mentioned. Even in such a case, the device cannot be damaged.
- a float switch can also be provided, which can protect the pump from running dry.

Abstract
The invention relates to a device (1) for conveying raw water or industrial water, in particular, out of wells, cisterns or surface waters, and for transforming it into potable water. The device comprises at least one feed pump (2) and a microfilter (3), which is located inside a housing (4) and which has an inlet (5) for the raw water as well as a tap (6) for the potable water that flows through the filter (3). The device (1), together with the housing (4) that contains the filter (3), has a second tap (7) which, inside this housing (4), is connected to the inlet (5) or to the line (9) via a bypass of the filter (3). This bypass is delimited at least in areas or partially by one side of the filter (3), on which the raw water flows. When withdrawing industrial water, this flows along the raw water side of the filter (3) and can automatically clean this raw water side. The device can thus make industrial water and potable water available, whereby the production of potable water can be ensured over a longer period of time by withdrawing industrial water.
Description
Vorrichtung zum Fördern von Roh- oder Brauchwasser Device for pumping raw or industrial water
Die Erfindung betrifft eine Vorrichtung zum Fördern von Roh- oder Brauchwasser, insbesondere aus Brunnen, Zisternen oder Oberflächengewässern, und zum Erzeugen von Trinkwasser daraus mit wenigstens einer Förderpumpe und einem wenigstens einen Mikrofilter enthaltenden Gehäuse, welches einen Zulauf für das Rohwasser und eine Zapfstelle für das durch den Filter geleitete Trinkwasser hat.The invention relates to a device for conveying raw or industrial water, in particular from wells, cisterns or surface waters, and for producing drinking water therefrom with at least one feed pump and a housing containing at least one microfilter, which has an inlet for the raw water and a tap for the drinking water passed through the filter.
Eine derartige Vorrichtung ist aus der FR 2 644 812 bekannt. Mit dieser bekannten Vorrichtung kann Roh- oder Brauchwasser in Trinkwasser umgewandelt werden. Dabei ist zu befürchten, daß der Filter nach einer relativ kurzen Zeit durch Verunreinigungen unbrauchbar wird. Darüber hinaus ist diese vorbekannte Vorrichtung aufwendig, so daß sie nicht geeignet ist, in abgelegenen Gegenden eine preiswerte Wasserversorgung zu ermöglichen.Such a device is known from FR 2 644 812. With this known device, raw or industrial water can be converted into drinking water. It is to be feared that after a relatively short time the filter will become unusable due to contamination. In addition, this previously known device is complex, so that it is not suitable for enabling inexpensive water supply in remote areas.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die einfach in der Herstellung, in der Montage und in der Benutzung ist und somit auch auf preiswerte Weise erforderliches Wasser zur Verfügung stellen kann, ohne daß der Filter zu schnell unbrauchbar wird.The invention is therefore based on the object to provide a device of the type mentioned, which is simple to manufacture, assemble and use and can therefore also provide the water required in a cost-effective manner without the filter being too fast becomes unusable.
Zur Lösung dieser Aufgabe ist die Vorrichtung der eingangs genannten Art dadurch gekennzeichnet, daß das den Filter enthaltende Gehäuse eine zweite Zapfstelle aufweist, die innerhalb des Gehäuses über eine Umgehung des Filters mit dem Zulauf verbunden ist, daß die Umgehung des Filters zumindest teilweise von einer Filterseite begrenzt ist, auf der das Rohwasser zuströmt, und daß beim Entnehmen von Brauchwasser aus der Vorrichtung dieses an der Rohwasserseite des Filters entlangströmt.
Auf diese Weise ergibt sich mit der erfindungsgemäßen Vorrichtung der erhebliche Vorteil, daß der Benutzer wahlweise Trinkwasser oder Brauchwasser entnehmen kann, wobei letzteres zur Bewässerung, zur Viehtränke oder auch für bestimmte Reinigungsvorgänge oder dergleichen geeignet ist. Gleichzeitig ergibt sich dadurch der Vorteil, daß bei der Entnahme von Brauchwasser der Filter außenseitig diesem Wasserstrom ausgesetzt und entsprechend gereinigt wird. Somit kann der Filter erheblich länger benutzt werden, um bei der Entnahme von Trinkwasser eine entsprechende Reinigung zu bewirken, bevor der Filter eventuell zusätzlich mechanisch oder in anderer Weise gereinigt oder gegebenenfalls ausgetauscht werden muß .To solve this problem, the device of the type mentioned is characterized in that the housing containing the filter has a second tap, which is connected within the housing via a bypass of the filter with the inlet, that the bypass of the filter at least partially from a filter side is limited, on which the raw water flows, and that when the process water is removed from the device, it flows along the raw water side of the filter. In this way, the device according to the invention has the considerable advantage that the user can selectively take drinking water or industrial water, the latter being suitable for irrigation, for livestock watering or also for certain cleaning processes or the like. At the same time, this results in the advantage that the outside of the filter is exposed to this water flow when the process water is withdrawn and cleaned accordingly. Thus, the filter can be used considerably longer to effect a corresponding cleaning when drinking water is removed before the filter may also have to be cleaned mechanically or in some other way or, if necessary, replaced.
Gerade bei der Wasserversorgung in entlegenen Gebieten besteht in der Regel die Notwendigkeit, sowohl Trinkwasser als auch Wasser zur Bewässerung, zur Reinigung von Geräten oder dergleichen oder zum Tränken von Vieh zu erhalten, so daß die erfindungsgemäße Vorrichtung die Anpassung der Wasserversorgung an diese unterschiedlichen Bedürfnisse erlaubt und dabei zusätzlich das Problem löst, einer Verschmutzung des Filters für die Trinkwasserversorgung möglichst lange entgegenzuwirken bzw. automatisch bei der Entnahme von Brauchwasser eine Reinigung des Filters zu bewirken.Especially when it comes to water supply in remote areas, there is usually a need to obtain both drinking water and water for irrigation, for cleaning equipment or the like or for watering cattle, so that the device according to the invention allows the water supply to be adapted to these different needs and additionally solves the problem of counteracting contamination of the filter for the drinking water supply for as long as possible, or automatically cleaning the filter when industrial water is withdrawn.
Besonders günstig ist es, wenn der Mikrofilter ein keramischer Mikrofilter ist. Dieser kann eine gute Filterwirkung auf das Rohwasser bei der Umwandlung in Trinkwasser ausüben und außerdem selbst gut gereinigt, gegebenenfalls nach längerer Zeit durch eine mechanische Bearbeitung der Zuströmseite wieder aufbereitet werden.It is particularly favorable if the microfilter is a ceramic microfilter. This can have a good filter effect on the raw water during the conversion into drinking water and can also be cleaned well, if necessary, can be reprocessed after a long time by mechanical processing on the inflow side.
Beispielsweise kann der Filter als Filterkerze ausgebildet und in dem Gehäuse angeordnet sein und der Zulauf des Brauchwassers kann zu der Außenseite dieses Filters führen und der Ablauf des
Trinkwassers kann mit der Innenseite des Filters verbunden sein. Dies ergibt eine konstruktive Anordnung, bei welcher also das Rohwasser von außen nach innen in den Filter eindringt, dabei gereinigt und dann als Trinkwasser abgezogen werden kann, während bei der Verwendung des Rohwassers als Brauchwasser diese relativ größere Oberfläche des Filters von dem Rohwasser angeströmt und gereinigt wird.For example, the filter can be designed as a filter candle and arranged in the housing and the inflow of the process water can lead to the outside of this filter and the outflow of the Drinking water can be connected to the inside of the filter. This results in a constructive arrangement in which the raw water penetrates into the filter from the outside inwards, can be cleaned and then removed as drinking water, while when the raw water is used as service water, this relatively larger surface of the filter is flown and cleaned by the raw water becomes.
Wenigstens an der zweiten Zapfstelle, insbesondere an beiden Zapfstellen, kann ein Absperrventil oder dergleichen offenbarer Verschluß vorgesehen sein. Im Hinblick auf den Strömungswiderstand des Filters würde es zwar genügen, wenn an der Zapfstelle des Brauchwassers ein Absperrventil oder dergleichen Verschluß vorhanden wäre, weil bei dem Öffnen dieses Verschlusses dann das Rohwasser unter Vermeidung des Strömungswiderstandes des Filters als Brauchwasser entnommen werden könnte. Besonders günstig ist es aber, wenn an beiden Zapfstellen jeweils ein Absperrventil oder dergleichen offenbarer Verschluß vorgesehen ist, so daß beim Entnehmen von Brauchwasser ein eventuell nur geringes Eindringen von Rohwasser in den Filter vermieden wird. Außerdem wird eine Verschmutzung von Außen durch das Absperrventil verhindert. Bei Verwendung nur eines Absperrventiles oder Verschlusses an der zweiten Zapfstelle kann ein Wasseraustritt aus der ersten Zapfstelle durch Abschalten oder Absperren der schon erwähnten Pumpe vermieden werden, wenn das Absperrventil bzw. der Verschluß der zweiten Zapfstelle geschlossen ist.At least at the second tap, in particular at both taps, a shut-off valve or the like can be provided. With regard to the flow resistance of the filter, it would be sufficient if a shut-off valve or the like were present at the tap of the process water, because when this valve was opened, the raw water could be removed as process water while avoiding the flow resistance of the filter. It is particularly favorable, however, if a shut-off valve or the like openable closure is provided at each of the two tapping points, so that a possible only slight penetration of raw water into the filter is avoided when used water is withdrawn. Pollution from the outside is also prevented by the shut-off valve. If only one shut-off valve or closure at the second tap is used, water leakage from the first tap can be avoided by switching off or shutting off the aforementioned pump when the shut-off valve or the closure of the second tap is closed.
Die Pumpe kann in der Zuleitung zu dem den Filter enthaltenden Gehäuse angeordnet sein. Somit kann sie möglichst nahe an der Entnahmestelle für das Rohwasser angeordnet und zumindest überwiegend als Druckpumpe wirkend, ausgebildet sein.The pump can be arranged in the feed line to the housing containing the filter. It can thus be arranged as close as possible to the extraction point for the raw water and at least predominantly designed to act as a pressure pump.
Gegebenenfalls kann die Pumpe auch eine Tauchpumpe sein, die über einen Schlauch oder dergleichen Leitung mit dem den Filter
enthaltenden Gehäuse verbunden ist. In diesem Falle kann die Pumpe in jedem Fall eine Druckpumpe sein, so daß eine Förderung des Rohwassers auch aus relativ großer Tiefe, beispielsweise aus relativ tiefen Brunnen möglich ist.If necessary, the pump can also be a submersible pump connected to the filter via a hose or the like containing housing is connected. In this case, the pump can in any case be a pressure pump, so that the raw water can also be pumped from a relatively large depth, for example from relatively deep wells.
In der Zuleitung zwischen Pumpe und Gehäuse kann ein Absperrventil, Schieber oder dergleichen Verschluß angeordnet sein. Somit kann vor allem bei Nichtgebrauch die Vorrichtung und der Bereich des Filters von der Zuleitung getrennt werden. Auch kann ein Rücklauf von in dem Gehäuse befindlichen Wasser vermieden werden. Auch bei Reparaturen an der Pumpe kann dies vorteilhaft sein.A shut-off valve, slide or similar closure can be arranged in the supply line between the pump and the housing. Thus, the device and the area of the filter can be separated from the supply line, especially when not in use. A return of water in the housing can also be avoided. This can also be advantageous for repairs to the pump.
Die Pumpe kann einen elektromotorischen Antrieb aufweisen und als Stromguelle können insbesonder ein oder mehrere Photovoltaik- oder Solarmodule vorgesehen sein. Dadurch eignet sich die Vorrichtung vor allem zur Benutzung in abgelegenen Gebieten, die keine Stromversorgung aber genügend Sonnenschein haben. Selbstverständlich wäre aber auch eine Stromerzeugung mit Windrad, Verbrennungsmotor oder dergleichen möglich. Vor allem in vielen Entwicklungsländern ist jedoch genügend Sonnenlicht vorhanden, um mit Hilfe einer Stromquelle auf der Basis von Solarmodulen eine unabhängige, überall einsetzbare Vorrichtung zur Wasserversorgung zur Verfügung zu stellen, die auch einfach und von lokalem Personal betrieben und gewartet werden kann. Die Solarmodule können mit einem oder mehreren Akkumulatoren zur Speicherung von elektrischer Energie verbunden sein. Somit kann die Vorrichtung auch eine gewisse Zeit lang betrieben werden, wenn eine Stromzufuhr nicht möglich ist, beispielsweise vorhandene Solarmodule mangels Sonnenschein keinen Strom erzeugen.The pump can have an electromotive drive and, in particular, one or more photovoltaic or solar modules can be provided as current sources. As a result, the device is particularly suitable for use in remote areas that have no power supply but sufficient sunshine. Of course, power generation with a wind turbine, internal combustion engine or the like would also be possible. Above all, in many developing countries there is enough sunlight to provide an independent, everywhere usable device for water supply with the help of a power source based on solar modules, which can also be operated and maintained easily and by local staff. The solar modules can be connected to one or more accumulators for storing electrical energy. Thus, the device can also be operated for a certain time when a power supply is not possible, for example existing solar modules do not generate electricity due to the lack of sunshine.
Das Gehäuse für den Filter, die Akkumulatoren und die Solarmodule können an einem gemeinsamen Gestell oder Gehäuse angebracht sein, so daß sich eine mobile und transportable Vorrichtung ergeben kann, die aber selbstverständlich auch fest installierbar
ist .The housing for the filter, the accumulators and the solar modules can be attached to a common frame or housing, so that a mobile and transportable device can result, which of course can also be permanently installed is.
Der Filter kann auswechselbar montiert sein. Zwar wird ein solches Auswechseln des Filters erst nach sehr langer Zeit erforderlich, da der Filter durch das zuströmende Rohwasser bei seiner Entnahme als Brauchwasser den Filter immer wieder automatisch reinigt, jedoch kann im Laufe einer langen Benutzungszeit dennoch die Leistung des Filters soweit nachlassen, daß ein Austausch zweckmäßig ist.The filter can be installed interchangeably. Such a replacement of the filter is only necessary after a very long time, since the filter cleans the filter automatically again and again when it is removed as process water by the incoming raw water, but the performance of the filter can nevertheless deteriorate to such an extent over a long period of use that a Exchange is appropriate.
Eine zweckmäßige Ausgestaltung der Vorrichtung kann darin bestehen, daß eine Verdränger-, Zentrifugal- oder Flügelzellenpumpe und ein in deren Nähe angeordnetes Überdruckventil zur Erzeugung eines konstanten Wasserdrucks vorgesehen sind. Somit können selbst in abgelegenen Gebieten hinsichtlich der Entnahme von Trinkwasser und/oder Brauchwasser vergleichbare Verhältnisse wie bei einer zentralen Wasserversorgung für den Benutzer geschaffen werden, das heißt beim Öffnen des entsprechenden Absperrventils oder Wasserhahns fließt das gewünschte Wasser - Trinkwasser oder Brauchwasser - sofort mit einem entsprechenden Druck aus diesem Wasserhahn.An expedient embodiment of the device can consist in that a positive displacement, centrifugal or vane pump and a pressure relief valve arranged in the vicinity thereof are provided for generating a constant water pressure. Thus, even in remote areas, comparable conditions can be created for the user with regard to the extraction of drinking water and / or process water, as with a central water supply, i.e. when the corresponding shut-off valve or tap is opened, the desired water - drinking water or process water - flows immediately with a corresponding one Pressure from this tap.
Es sei noch erwähnt, daß auf der Saugseite der Pumpe ein Filter, insbesondere ein Feinfilter angeordnet sein kann. Dadurch können im Rohwasser enthaltene Bestandteile schon zu einem großen Teil zurückgehalten werden, so daß der in der Vorrichtung angeordnete Mikrofilter weniger belastet wird und aufgrund der automatischen Reinigung entsprechend länger zur Verfügung steht.It should also be mentioned that a filter, in particular a fine filter, can be arranged on the suction side of the pump. In this way, constituents contained in the raw water can already be retained to a large extent, so that the microfilter arranged in the device is less loaded and is available for a correspondingly longer time due to the automatic cleaning.
Vor allem bei der Kombination einzelner oder mehrerer oder aller der vorbeschriebenen Merkmale und Maßnahmen ergibt sich eine Vorrichtung der eingangs genannten Art, die in ländlichen Gebieten und insbesondere in Entwicklungsländern eingesetzt werden kann und ein kompaktes, von Wasserleitungen und Netzstrom un-
abhängiges Gerät zur Trink- und Brauchwasserversorgung darstellt . Dabei kann zum Beispiel bei einer Brunnentiefe von 20 mtr. und einem für Nordafrika typischen solaren Sonnenstrahlungsangebot etwa 200 ltr. Trinkwasser und 1.000 ltr. Brauchwasser zur Verfügung gestellt werden.Especially when combining one or more or all of the features and measures described above, a device of the type mentioned at the outset results which can be used in rural areas and in particular in developing countries and which has a compact structure made up of water pipes and mains electricity. dependent device for drinking and industrial water supply. For example, with a well depth of 20 mtr. and a typical solar radiation offer for North Africa about 200 ltr. Drinking water and 1,000 l. Process water can be made available.
Dabei wird nicht nur innerhalb dieses kompakten Gerätes die Anwendung eines Desinfektionsprozesses auf das Trinkwasser sichergestellt, sondern es werden gleichzeitig auch potentielle antrophogene Verschmutzungsquellen für das Wasser zwischen Förder- und Aufbereitungseinheit weitestgehend vermieden. Ferner kann auf einen Wasserspeicher, der eine weitere Verkeimungsquelle darstellen könnte, verzichtet werden.Not only is the use of a disinfection process on drinking water ensured within this compact device, but at the same time potential sources of antrophogenic pollution for the water between the conveying and treatment unit are largely avoided. Furthermore, a water reservoir, which could represent a further source of germs, can be dispensed with.
Die Verwendung eines keramischen Mikrofilters als Desinfektionseinheit hat dabei den Vorteil, daß einerseits die chemische Beschaffenheit des Trinkwassers und damit auch sein Geruch und sein Geschmack nicht verändert werden andererseits aber doch eine ausreichend sichere Desinfektion erreicht wird. Aufgrund der physikalischen Wirkungsweise des Siebfilters - im wesentlichen eine Siebwirkung - ist die Vorrichtung vor allem im Hinblick auf größere Krankheitserreger wie zum Beispiel Parasiten und solche, die sich bevorzugt an im Wasser befindliche Schwebstoffe anlagern, besonders wirksam.The use of a ceramic microfilter as a disinfection unit has the advantage that, on the one hand, the chemical nature of the drinking water and thus also its smell and taste are not changed, but on the other hand a sufficiently safe disinfection is achieved. Due to the physical mode of operation of the sieve filter - essentially a sieve effect - the device is particularly effective with regard to larger pathogens such as parasites and those that preferentially accumulate in suspended water.
Eine manuelle Reinigung des Mikrofilters - sofern überhaupt notwendig - kommt ohne chemische Hilfsmittel aus . Als Reinigungsmittel genügt in der Regel ein handelsüblicher Schwamm. Als Reinigungsflüssigkeit kann Rohwasser verwendet werden.Manual cleaning of the microfilter - if necessary at all - does not require any chemical aids. A commercially available sponge is usually sufficient as a cleaning agent. Raw water can be used as the cleaning liquid.
Die Desinfektionswirkung des Filters muß weder über eine chemische Analytik noch über eine (komplizierte) elektronische Überwachung nachgeprüft werden. Als einziges Hilfsmittel genügt eine Schiebleere, mit der die verbleibende Dicke des Keramikfliters
nach einer entsprechenden mechanischen Behandlung überprüft und anhand welcher entschieden werden kann, wann der Filter aufgrund einer Reduzierung der desinfektionswirksamen Schicht ausgewechselt werden muß. Somit kann selbst ungelerntes Personal den Betrieb und die Wartung dieser Vorrichtung durchführen.The disinfectant effect of the filter does not need to be checked using chemical analysis or (complicated) electronic monitoring. The only auxiliary means is a sliding void with which the remaining thickness of the ceramic tinsel is checked after appropriate mechanical treatment and on the basis of which it can be decided when the filter must be replaced due to a reduction in the disinfectant layer. Thus, even unskilled personnel can operate and maintain this device.
Dadurch, daß das Trinkwasser durch den Filter hindurchgedrückt, daß Brauchwasser aber an dem Filter vorbeigeleitet wird, findet bei jeder Entnahme von Brauchwasser automatisch eine Abreinigung des Filters statt. Dies reduziert die Notwendigkeit manueller Reinigung und vergrößert demzufolge die Standzeit des Filters erheblich. Dabei ist auch als vorteilhaft anzusehen, daß für diese Reinigung kein zusätzliches Wasser und auch kein aufbereitetes Wasser benötigt wird. Das zugeführte Wasser kann also zu 100 Prozent genutzt werden.Due to the fact that the drinking water is pushed through the filter, but that industrial water is led past the filter, the filter is automatically cleaned each time industrial water is withdrawn. This reduces the need for manual cleaning and consequently increases the service life of the filter considerably. It is also to be regarded as advantageous that no additional water and no treated water are required for this cleaning. The supplied water can therefore be used 100 percent.
Die Bedienung ist äußerst einfach, weil ein einziger Schalter genügt, um die Vorrichtung durch Einschalten der Pumpe in Betrieb zu nehmen. Der Nutzer braucht dann nur noch den richtigen Wasserhahn zu öffnen, um entweder Trinkwasser und Brauchwasser zu zapfen. Öffent er beide Hähne erhält er wegen des Strömungswiderstands des Filters Brauchwasser. Öffent er keinen der Hähne, wird das Wasser über das schon erwähnte Überdruckventil in die Wasserquelle zurückgeleitet . Auch in einem solchen Fall kann also kein Schaden an der Vorrichtung entstehen. Dabei kann auch noch ein Schwimmschalter vorgesehen werden, der die Pumpe vor einem trockenlaufen schützen kann.Operation is extremely simple because a single switch is all that is required to start up the device by switching on the pump. The user then only needs to open the correct tap to tap either drinking water or process water. If he taps both taps in public, he receives hot water due to the flow resistance of the filter. If he does not publicize any of the taps, the water is returned to the water source via the pressure relief valve already mentioned. Even in such a case, the device cannot be damaged. A float switch can also be provided, which can protect the pump from running dry.
Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigt in schematisierter Darstellung:An embodiment of the invention is described below with reference to the drawing. It shows in a schematic representation:
Fig.1 eine schaubildliche Ansicht einer erfindungsgemäßen Vorrichtung, wobei ein den Filter enthaltendes Gehäuse
mit weiteren Aggregaten in einem Gestell angeordnet ist, auf welchem zur Stromversorgung Solarmodule installiert sind,1 shows a perspective view of a device according to the invention, with a housing containing the filter is arranged with further units in a frame on which solar modules are installed for power supply,
Fig.2 einen Längsschnitt der Vorrichtung, wobei der Zapfhahn für das Trinkwasser geöffnet und der für das Brauchwasser geschlossen ist, so daß das zuströmende Rohwasser durch den Mikrofilter zu der Zapfstelle für Trinkwasser gelangt, sowie2 shows a longitudinal section of the device, the tap being open for the drinking water and being closed for the service water, so that the inflowing raw water passes through the microfilter to the tap for drinking water, and
Fig.3 eine der Fig.2 entsprechende Darstellung, wobei der3 shows a representation corresponding to FIG. 2, the
Zapfhahn für das Trinkwasser geschlossen und der für das Brauchwasser geöffent ist, so daß das zuströmendeTap for the drinking water closed and which is open for the domestic water, so that the inflowing
Rohwasser die Außenseite des Filters umspült und reinigt und als Brauchwasser aus der Vorrichtung austritt .Raw water rinses and cleans the outside of the filter and exits the device as process water.
Eine im Ganzen mit 1 bezeichnete Vorrichtung dient zum Fördern von Roh- oder Brauchwasser zum Beispiel aus einem Brunnen, einer Zisterne oder einem Oberflächengewässer.A device designated as a whole by 1 is used to convey raw or industrial water, for example from a well, a cistern or a surface water.
Zum Erzeugen von Trinkwasser ist dabei eine Förderpumpe 2 und ein einen Mikrofilter 3 enthaltendes Gehäuse 4 vorgesehen, welches einen Zulauf 5 für das Rohwasser hat, der mit der Pumpe 2 verbunden ist. Ferner ist eine Zapfstelle 6 für das durch den Filter 3 geleitetes Trinkwasser vorhanden, so daß bei laufender Pumpe und geöffneter Zapfstelle 6 das zuströmende Rohwasser als durch den Filter 3 gereinigtes Trinkwasser entnommen werden kann, wie es in Fig. 2 auch durch die Pfeile dargestellt ist.To produce drinking water, a feed pump 2 and a housing 4 containing a microfilter 3 are provided, which has an inlet 5 for the raw water, which is connected to the pump 2. There is also a tap 6 for the drinking water passed through the filter 3, so that with the pump running and the tap 6 open, the inflowing raw water can be removed as drinking water cleaned by the filter 3, as is also shown in FIG. 2 by the arrows ,
Das den Filter 3 enthaltende Gehäuse 4 weist außerdem, was vor allen in den Fig.2 und 3 verdeutlicht ist, eine zweite Zapfstelle 7 auf, die innerhalb des Gehäuses 4 über eine Umgehung des Filters 3 mit dem Zulauf 5 verbunden ist .
Diese Umgehung des Filters 3 innerhalb des Gehäuses 4 ist dabei teilweise durch eine Filterseite begrenzt, nämlich diejenige Seite des Filters 3, auf welcher das Rohwasser zuströmt. Gemäß Fig.3 strömt also beim Entnehmen von Brauchwasser aus der Vorrichtung 1 dieses an der Rohwasserseite des Filters 3 entlang und kann diese dabei von dort anhaftenden Verunreinigungen reinigen, die zuvor an dem Filter 3 angelagert werden, wenn gemäß Fig.2 Trinkwasser entnommen und dabei der Filter 3 von dem Rohwasser durchströmt wird.The housing 4 containing the filter 3 also has, as is clear above all in FIGS. 2 and 3, a second tap 7 which is connected to the inlet 5 within the housing 4 by bypassing the filter 3. This bypassing the filter 3 within the housing 4 is partially limited by a filter side, namely that side of the filter 3 on which the raw water flows. According to FIG. 3, when process water is withdrawn from the device 1, it flows along the raw water side of the filter 3 and can thereby clean any contaminants adhering to it, which are previously deposited on the filter 3 if, according to FIG the filter 3 is flowed through by the raw water.
Der Mikrofilter 3 ist dabei zweckmäßigerweise ein keramischer Mikrofilter, der auch ab und zu eine mechanische zusätzliche Reinigung ermöglicht .The microfilter 3 is expediently a ceramic microfilter which also occasionally enables additional mechanical cleaning.
Dabei ist in den Fig.2 und 3 dargestellt, daß der Filter 3 als Filterkerze ausgebildet und in dem Gehäuse 4 angeordnet ist, wobei der Zulauf 5 des Rohwassers zu der Außenseihe dieses Filters 3 führt und der Ablauf des Trinkwassers mit der Innenseite dieses Filters 3 verbunden ist. Dies ist in Fig.2 durch die Pfeile verdeutlicht.It is shown in FIGS. 2 and 3 that the filter 3 is designed as a filter candle and is arranged in the housing 4, the inlet 5 of the raw water leading to the outside of this filter 3 and the outlet of the drinking water with the inside of this filter 3 connected is. This is illustrated in Figure 2 by the arrows.
Zwar könnte es genügen, wenn an der Zapfstelle 7 für das Brauchwasser ein Absperrventil 8 oder dergleichen offenbarer Verschluß vorgesehen ist, jedoch ist im Ausführungsbeispiel vorgesehen, daß an beiden Zapfstellen 6 und 7 ein solches Absperrventil 8 angeordnet ist. Somit kann der Benutzer wahlweise das eine oder andere Absperrventil 8 öffnen, um Brauchwasser oder Trinkwasser zu erhalten.It may be sufficient if a shut-off valve 8 or the like, which can be opened, is provided at the tap 7 for the process water, but in the exemplary embodiment it is provided that such a shut-off valve 8 is arranged at both taps 6 and 7. Thus, the user can selectively open one or the other shut-off valve 8 in order to receive process water or drinking water.
Die Pumpe 2 ist in einer Zuleitung 9 zu dem den Filter 3 enthaltenden Gehäuse 4 angeordnet, welche Zuleitung 9 zu dem Zulauf 5 führt. Dabei weist diese Zuleitung 9 kurz vor dem Eintritt in das Gehäuse 4 ein Absperrventil 10 auf, so daß die Vorrichtung beziehungsweise vor allem das Gehäuse 4 mit dem Filter auch von
der Pumpe 2 getrennt werden kann.The pump 2 is arranged in a feed line 9 to the housing 4 containing the filter 3, which feed line 9 leads to the inlet 5. This feed line 9 has a shut-off valve 10 shortly before entry into the housing 4, so that the device or, in particular, the housing 4 with the filter also from the pump 2 can be separated.
Die Pumpe 2 weist einen nicht näher dargestellten elektromotorischen Antrieb auf. Als Stromquelle sind dabei gemäß Fig.2 im Ausführungsbeispiel 2 Fotovoltaik- oder Solarmodule 11 vorgesehen, die die Vorrichtung 1 von einem Stromnetz unabhängig machen, so daß die Vorrichtung 1 auch in abgelegenen Gegenden zum Einsatz kommen kann. Dabei sind diese Solarmodule 11 mit Akkumulatoren 12 für Speicherung von elektrischer Engerie verbunden, so daß der Ausfall von Sonnenschein für eine gewisse Zeit überbrückt werden kann. In Fig.1 erkennt man zusätzlich eine elektronische Steuereinheit 13 , mit welcher der Antrieb der Pumpe 2 entsprechend angesteuert werden kann.The pump 2 has an electromotive drive, not shown in detail. According to FIG. 2 in the exemplary embodiment, 2 photovoltaic or solar modules 11 are provided as the current source, which make the device 1 independent of a power grid, so that the device 1 can also be used in remote areas. These solar modules 11 are connected to accumulators 12 for storing electrical energy, so that the loss of sunshine can be bridged for a certain time. An additional electronic control unit 13 can be seen in FIG. 1, with which the drive of the pump 2 can be controlled accordingly.
Das Gehäuse 4 für den Filter 3, die Akkumulatoren 12, die Steuereinheit 13 und die Solarmodule 11 sind dabei gemäß Fig.1 an einem gemeinsamen Gestell 14 oder Gehäuse angebracht, welches fest installiert oder aber transportabel sein kann, so daß auch ein schneller und einfacher Ortswechsel möglich ist.The housing 4 for the filter 3, the accumulators 12, the control unit 13 and the solar modules 11 are attached to a common frame 14 or housing according to FIG. 1, which can be permanently installed or transportable, so that it is also quicker and easier Change of location is possible.
Es sei noch erwähnt, daß der Filter 3 auswechselbar montiert sein kann, so daß er auch gegen einen neuen Filter 3 ausgetauscht werden kann. Die Pumpe 2 kann eine Verdränger-, Zentrifugal- oder Flügelzellenpumpe sein und mit einem insbesondere in ihrer Nähe angeordneten Überdruckventil zur Erzeugung eines konstanten Wasserdrucks dienen, selbst wenn kein Trink- oder Brauchwasser entnommen wird. Dadurch steht zu jeder Zeit an jeder Zapfstelle 6 oder 7 Wasser mit einem vorgegebenen Druck zur Verfügung.It should also be mentioned that the filter 3 can be mounted interchangeably so that it can also be exchanged for a new filter 3. The pump 2 can be a positive displacement, centrifugal or vane cell pump and, with a pressure relief valve arranged in particular in its vicinity, can be used to generate a constant water pressure, even if no drinking or process water is drawn off. As a result, 6 or 7 water with a predetermined pressure is available at each tap at any time.
Dabei ist es günstig, wenn die Pumpe 2 eine Tauchpumpe ist, die über einen Schlauch oder dergleichen Leitung 9 mit dem den Filter 3 enthaltenden Gehäuse 4 verbunden ist, so daß entsprechend große Förderhöhen möglich sind.
Auf der Saugseite der Pumpe kann ein nicht näher dargestellter Filter, insbesondere ein Feinfilter angeordnet sein, der die Lebensdauer des Mikrofilters 3 innerhalb des Gehäuses 4 verlängert .It is advantageous if the pump 2 is a submersible pump, which is connected via a hose or the like line 9 to the housing 4 containing the filter 3, so that correspondingly high delivery heights are possible. A filter (not shown in detail), in particular a fine filter, can be arranged on the suction side of the pump, which extends the life of the microfilter 3 within the housing 4.
Die Vorrichtung 1 zum Fördern von Roh- oder Brauchwasser insbesondere aus Brunnen, Zisternen oder Oberflächengewässern und zum Umwandeln in Trinkwasser weist wenigstens eine Förderpumpe 2 und innerhalb eines Gehäuses 4 einen Mikrofilter 3 mit einem Zulauf 5 für das Rohwasser und einer Zapfstelle 6 für das Trinkwasser auf, welches durch den Filter 3 fließt. Die Vorrichtung 1 und dabei daß den Filter 3 enthaltende Gehäuse 4 hat eine zweite Zapfstelle 7, die innerhalb dieses Gehäuses 4 über eine Umgehung des Filters 3 mit dem Zulauf 5 beziehungsweise der Zuleitung 9 verbunden ist. Diese Umgehung wird zumindest bereichs- oder teilweise von einer Seite des Filters 3 begrenzt, auf der das Rohwasser zuströmt. Beim Entnehmen von Brauchwasser strömt dieses also an der Rohwasserseite des Filters 3 entlang und kann diese automatisch reinigen. Die Vorrichtung kann also Brauchwasser und Trinkwasser zur Verfügung stellen, wobei in vorteilhafter Weise durch die Entnahme von Brauchwasser die Erzeugung von Trinkwasser über einen längeren Zeitraum sichergestellt werden kann.
The device 1 for conveying raw or industrial water, in particular from wells, cisterns or surface waters and for converting it into drinking water, has at least one feed pump 2 and, within a housing 4, a microfilter 3 with an inlet 5 for the raw water and a tap 6 for the drinking water , which flows through the filter 3. The device 1 and the housing 3 containing the filter 3 has a second tap 7 which is connected within this housing 4 by bypassing the filter 3 to the inlet 5 or the feed line 9. This bypass is at least partially or partially limited by one side of the filter 3, on which the raw water flows. When hot water is withdrawn, it flows along the raw water side of the filter 3 and can clean it automatically. The device can therefore provide domestic water and drinking water, the production of drinking water being able to be ensured over a longer period of time in an advantageous manner by removing domestic water.
