Description

Bei Trinkwasserfflteranlagen ist von Zeit zu Zeit eine Rückspülung der Filter erforderlich. Bisher wurde diese Rückspülung vorgenommen, wenn durch Messungen das Verschlammen der Filter bis auf den zulässigen Grad festgestellt worden war. Das Wesen der vorliegenden Erfindung besteht darin, daß das Rückspülen der Filter durch eine Automatik erfolgt, um die Wartung der Anlage zu erleichtern und ein übermäßiges Verschmutzen der Filter und daraus resultierende Betriebsstörungen zu vermeiden. Diese selbsttätige Filterspülung wird gemäß der Erfindung dadurch erreicht, daß in der Anlage mindestens zwei Schlammfilter oder filtergruppen vorgesehen sind, die wechselweise, in regelmäßigem, durch ein Uhrschaltwerk bestimmten Zeitabstand selbsttätig rückgespült werden. Man kann dann das Schlammwasser selbst zur Rückspülung benutzen, indem von den beiden Filtern eines zur Reinigung des für das andere Filter oder die andere Filtergruppe benötigten Spülwassers benutzt wird. Die Einrichtung ist insbesondere dort geeignet, wo eine ordentliche Wartung der Anlage in Frage gestellt ist, wie z. B. bei Trinkwasserfilteranlagen für die Tropen.In the case of drinking water filter systems, the filter must be backwashed from time to time. So far, this backwashing has been carried out when measurements have shown that the filters have become silted up to the permissible level. The essence of the present invention is that the backwashing of the filters is carried out by an automatic system in order to facilitate the maintenance of the system and to avoid excessive contamination of the filters and the resultant malfunctions. This automatic filter rinsing is achieved according to the invention in that at least two sludge filters or in the system filter groups are provided that are alternately backwashed automatically at regular intervals determined by a clock mechanism. The sludge water itself can then be used for backwashing, in that one of the two filters is used to clean the rinsing water required for the other filter or the other filter group. The device is particularly suitable where proper maintenance of the system is in question, such as. B. in drinking water filter systems for the tropics.

In der Abbildung ist die Erfindung beispielsweise veranschaulicht. Das zu filternde Schlammwasser wird beispielsweise von einem Fluß durch eine Pumpe P über Zweiwegeventile V1 und V2 zwei Schlammffltern F1 und F2 zugeführt und weiter über zwei Entkeimfilter E' und E2 unter Zwischenschaltung eines Druckwindkessels D zu den Verbrauchern gefördert. Die Pumpe P wird von einem Benzinmotor K angetrieben. For example, the invention is illustrated in the figure. The sludge water to be filtered is for example from a river through a pump P fed to two sludge filters F1 and F2 via two-way valves V1 and V2 and on via two sterilization filters E 'and E2 with the interposition of a pressure air vessel D promoted to consumers. The pump P is driven by a gasoline engine K.

Zwecks Rückspülung der Filter F1 und F2 werden von einem Uhrschaltwerk S aus die Zweiwegeventile V1 und V2 sowie ein in der Verbindung zwischen den Schlammfiltern und den Entkeimfiltern liegendes Absperrventil V3 gesteuert. Diese Steuerung geschieht in der Weise, daß in bestimmten Zeitabständen beispielsweise das Zweiwegeventil V2 derart umgelegt wird, daß das von der Pumpe geförderte Schlammwasser nur noch über das Schlammfilter F1 läuft und, bei gleichzeitigem Schließen des Absperrventils V3, seinen Weg rückläufig über das Filter F2 und das Zweiwegeventil V2 zum Spülwasserablauf nimmt. For the purpose of backwashing the filters F1 and F2, a clock mechanism S from the two-way valves V1 and V2 and one in the connection between the sludge filters and the isolating filter located shut-off valve V3 controlled. This control happens in such a way that at certain time intervals, for example, the two-way valve V2 is turned over in such a way that the sludge water delivered by the pump only runs through the sludge filter F1 and, at the same time, the shut-off valve closes V3, its way backwards via the filter F2 and the two-way valve V2 to the flushing water drain takes.

Nach z. B. Iominutiger Rückspülung wird durch das Uhrschaltwerk S der normale Filterbetrieb wiederhergestellt. Ebenso wird nach einiger Zeit das Schlammfilter F1 zurückgespült, indem das Schlammwasser über das FilterF2 rückwärts durch das Filter F1 und das entsprechend umgelegte Zweiwegeventil V in den Spülwasserabfluß gefördert wird.After z. B. Iominutiger backwash is through the clock mechanism S normal filter operation restored. The sludge filter will also work after a while F1 backwashed by the sludge water over the filterF2 backwards through the Filter F1 and the correspondingly reversed two-way valve V into the flushing water drain is promoted.

Die Pumpenleistung wird entsprechend dem Verbrauch geregelt. Dies geschieht vom Druck des Windkessels D aus, durch den ein Relais R betätigt wird. Dieses Relais, ebenso wie auch die Ventile Vi, V2, V3, werden durch einen Kompressor C betrieben. Bei Ansprechen des Relais R infolge gespeicherten Druckes im Windkessel D wird durch einen Gemischregler G die Füllung des Benzinmotors K verstellt. Außerdem wird ein Zweiwegeventil L betätigt, durch das die Pumpe P teilweise oder ganz auf Leerlauf umgeschaltet wird. The pump output is regulated according to consumption. this occurs from the pressure of the air chamber D, by which a relay R is actuated. This relay, as well as the valves Vi, V2, V3, are operated by a compressor C operated. When relay R responds as a result of the pressure stored in the air tank D the filling of the gasoline engine K is adjusted by a mixture regulator G. aside from that a two-way valve L is operated, through which the pump P partially or completely Idle is switched.
