   Zur Reinigung des Filtermateriales dient nun die folgende Einrichtung : In den Raum   I   unterhalb des kegelförmigen Zwischenbodens b mündet eine Rohrleitung o mit einem Absperrorgan p zur Zuführung des Waschwassers und an der tiefsten Stelle des kegelförmigen Zwischenbodens b ist ein Kasten q angeordnet, dessen obere Begrenzung sich an den untersten Teil des kegelförmigen Bodens b anschmiegt bzw. selbst den untersten Teil dieses kegelförmigen Zwischen- 
 EMI2.2 
 sperrorgan s enthält, und ist das Absperrorgan s geöffnet, so strömt die Druckluft in den   Kasten q   und wird von hier in feinen Strömen durch die oberen Durchbrechungen dieses Kastens durch das Filtermaterial hindurch in das Rohr   d   geleistet. 



     Holl   das Filtermaterial gereinigt werden, so wird, solange noch das Absperrorgan s der Druckluftleitung r geschlossen ist, das Absperrorgan p der Waschwasserleitung v geöffnet. Vorher wurden natürlich auch das Absperrorgan i der Rohwasserleitung und das Absperrorgan n der
Reinwasserleitung gesperrt. Zunächst füllt sich nun der Raum l unterhalb des kegelförmigen   ZwLschenhodens b   mit dem Waschwasser und nach und nach dringt das Wasser auch durch die Durchbrechungen des Zwischenbodens b hindurch und schwemmt das Filtermaterial auf, so dass ein leiehtfüssiges Gemisch von Wasser und Filtermaterial entsteht. Ist das Filtermaterial genügend 
 EMI2.3 
 in verteiltem Zustande in das Rohr d, das gleichfalls Filtermaterial mit Wasser gemischt enthält, gelangt.

   Durch das Eindringen von Luftblasen in das im Rohr d enthaltene Gemisch wird dessen Volimgewicht gegenüber dem Gemisch ausserhalb des Rohres d verringert und es entsteht im 
 EMI2.4 
 am oberen Ende des Rohres d aus dem Gemisch austrttende Luft kann durch ein Absperrorgan u Im oberen Teil des   Behalf, ers   a entweichen. 



   Wie bereits eingangs erwähnt, kann eine   Ahzweigung der Waschwasserleitung o auch   in den Kastenqhineingeführtwerden.

 EMI2.1
 



   The following device is used to clean the filter material: A pipe o with a shut-off device p for supplying the washing water opens into space I below the conical intermediate floor b and a box q is arranged at the deepest point of the conical intermediate floor b, the upper limit of which is hugs the lowest part of the conical bottom b or even the lowest part of this conical intermediate
 EMI2.2
 contains the shut-off element s, and if the shut-off element s is open, the compressed air flows into the box q and from here is carried out in fine streams through the upper openings of this box through the filter material into the pipe d.



     Holl the filter material is cleaned, as long as the shut-off element s of the compressed air line r is still closed, the shut-off element p of the washing water line v is opened. Before that, of course, the shut-off device i of the raw water pipe and the shut-off device n the
Clean water line blocked. First, space 1 below the conical diaphragmatic diaphragm b is filled with the washing water and gradually the water also penetrates through the openings in the intermediate floor b and floats up the filter material, so that a leeward mixture of water and filter material is created. Is the filter material sufficient
 EMI2.3
 in a distributed state in the pipe d, which also contains filter material mixed with water, arrives.

   As a result of the penetration of air bubbles into the mixture contained in the pipe d, its volume weight is reduced compared to the mixture outside the pipe d and it arises in the
 EMI2.4
 Air escaping from the mixture at the upper end of the pipe d can escape through a shut-off element u in the upper part of the container a.



   As already mentioned at the beginning, a branch of the washing water line o can also be introduced into the box.
