Die vorliegende Erfindung ist eine weitereThe present invention is another
Ausgestaltung des Trommelfilters nach Pa-Design of the drum filter according to Pa-
■ tent 248611. Sic besteht darin, daß bei einem Trommelfilter nach dem genannten Patent, bei dem die Filter fläche dadurch gereinigt wird, daß bestimmte Mengen von der Jm Innern der Filtertrommel befindlichen ge-■ tent 248611. It consists in the fact that with a drum filter according to the patent mentioned, in which the filter surface is cleaned in that certain amounts of the Inside the filter drum
' reinigten Flüssigkeit durch die Filterfläche hindurch in die ungereinigte Flüssigkeit zurückgefiltert werden, die Austragsstelle unterhalb des Achsenniveaus der Trommel angeordnet wird, wobei an dem inneren Umfange der Trommel Schöpfvorrichtungen vorgesehen sind. ·'The cleaned liquid is filtered back through the filter surface into the uncleaned liquid are arranged, the discharge point below the axis level of the drum is provided, scooping devices being provided on the inner periphery of the drum are. ·
Dadurch, daß sich die Austragsstelle unterhalb des Achsenniveaus der Trommel befindet, wird der Vorteil erreicht, daß die geschöpfte und zurückflutende Flüssigkeit mit den abgespülten Schmutzmengen glatt vom Siebmantel senkrecht nach unten abtropfen kann, und daß so die Schmutzteilchen nicht mehr mit der Filterfläche in Berührung kommen, wodurch eine sichere Reinigung des Trommelmantels bzw. der Filterfläche gewährleistet wird. Die an der Innenwand der. Filtertrommel angeordneten Schöpf vorrichtungen heben beim.Drehen der Trommel eine ; geringe Menge der gereinigten Flüssigkeit aus dem Wasser heraus, die dann durch den Filtermantel in die ungereinigte Flüssigkeit zurückfließt, ,Ferner ist ein Sandfang vorgesehen, in dem sich die schweren Fremdkörperchen absetzen, und aus welchem sie mittels irgendeines Förderers von beliebiger Bauart entfernt werden.Because the discharge point is below the axis level of the drum, the advantage is achieved that the scooped and flowing back liquid with The rinsed amounts of dirt drip straight down from the sieve casing vertically can, and so that the dirt particles no longer come into contact with the filter surface, which ensures safe cleaning of the drum shell or the filter surface will. The one on the inner wall of the. Scooping devices arranged in the filter drum lift a ; small amount of the purified liquid out of the water, which then passes through the Filter jacket flows back into the uncleaned liquid, a sand trap is also provided, in which the heavy foreign bodies settle, and from which they mean any conveyor of any type.
Die beiliegende Zeichnung gibt ein Beispiel für die Ausführung der Erfindung. Fig. ι zeigt eine Trommelfilteranlage im Schnitt, und Fig. 2 einen Teil der Trommelwandung mit den an der Wand radial angeordneten "Schöpfvorrichtungen.· ' .The accompanying drawing gives an example of the implementation of the invention. Fig. Ι shows a drum filter system in section, and FIG. 2 shows part of the drum wall with the "scooping devices. · 'arranged radially on the wall.
α zeigt den Flüssigkeitsbehälter, der bei b als Sandfang ausgebildet ist. c ist die Filtertrommel und d sind an ihrer Innenwand angeordnete Stäbe. f ist die ungereinigte Flüssigkeit und g die gereinigte. /) veranschaulicht einen Förderer, der natürlich auch von jeder anderen Bauart sein kann. α shows the liquid container, which is designed as a sand trap at b. c is the filter drum and d are rods arranged on its inner wall. f is the unpurified liquid and g is the purified one. /) illustrates a conveyor, which of course can also be of any other type.
