PATENTAMT.PATENT OFFICE.
Es ist bekannt, die Reinigung von Filtern mit körnigem Filtermaterial dadurch vorzunehmen, daß man unter der Filterschicht Druckluft oder Druckwasser oder beides einleitet, wodurch eine Aufwirbelung des Filtermateriales und dadurch eine. Entfernung des zurückgehaltenen Schlammes erzielt werden soll. Es hat sich nun gezeigt, daß die Reinigung derart eingerichteter Filter einerseits nurIt is known that filters with granular filter material can be cleaned by that compressed air or pressurized water or both are introduced under the filter layer, whereby a whirling up of the filter material and thereby a. Removal of the retained sludge can be achieved target. It has now been shown that the cleaning of filters set up in this way on the one hand only
ίο eine unvollkommene ist, andererseits sehr lange Zeit und viel Waschwasser benötigt, was wohl in erster Linie darin seine Erklärung findet, daß das Filtermaterial durch das immer stets unter gleichem Druck nachströmende Reinigungsmittel in Schwebe erhalten wird und durch das gelockerte Gefüge eine weniger energische Berührung des Reinigungsmittels mit dem Filtermaterial stattfindet als bei Beginn des Waschens, wo das Reinigungsmittel in den gelagerten Filterkörper eindringt und sich erst durch stete Reibung in den einzelnen Körnern nach oben hin Bahn macht.ίο is imperfect, on the other hand very long Time and a lot of washing water needed, which is probably primarily explained by it, that the filter material through the cleaning agent always flowing in under the same pressure is kept in suspension and, due to the loosened structure, a less energetic contact with the cleaning agent with the filter material takes place than at the start of washing where the detergent penetrates into the stored filter body and only through constant friction in the individual Grains upwards.
Zweck vorliegender Erfindung ist es nun, den vorliegenden Übelstand zu beseitigen, und wird dies dadurch erreicht, daß das Reinigungsmittel bei jedem Reinigungsvorgange in mehrfachen Stößen unter größerem Druck unter das Filtermaterial geleitet und dem Filtermaterial Zeit gelassen wird, sich immer wieder zu setzen, damit der nächste Stoß des Reinigungsmittels das geschichtete Filtermaterial trifft und so eine vollkommenere Reinigung desselben bewirkt. Während der Zeit zwischen den einzelnen Stößen braucht der Zulauf des Reinigungsmittels nicht ganz abgestellt zu werden, sondern es kann auch während dieser Pausen in ruhigem Strome weiter 40 The purpose of the present invention is to eliminate the present drawback, and this is achieved in that the cleaning agent is passed under the filter material in multiple bursts under greater pressure with each cleaning process and the filter material is given time to sit down again and again so that the The next blow of the cleaning agent hits the layered filter material and thus effects a more complete cleaning of the same. During the time between the individual joints of the inlet need not be turned off completely the cleaning agent, but it can also during these pauses in calm river on 40
durch das Filter geleitet werden, wodurch die angestrebte Wirkung des Sichsetzens des Filtermaterials nicht beeinträchtigt wird. Bei Verwendung von Wasser und Luft als Reinigungsmittel können sowohl beide gleichzeitig als auch abwechselnd eines nach dem anderen stoßweise eingeführt werden. Auch ist es möglich, eines der beiden Mittel im gleichmäßigen Strome von unten nach oben durch das Filter zu leiten, während das zweite Mittel, wie vorbeschrieben, stoßweise eingeführt wird.be passed through the filter, thereby creating the desired effect of the filter material settling is not affected. When using water and air as cleaning agents Both can be introduced simultaneously or alternately one after the other in bursts. It is also possible one of the two means in an even flow from bottom to top through the filter to conduct, while the second agent, as described above, is introduced intermittently.
