Description

Schwimmfiltermaterial.Swimming filter material.

Gegenstand der vorliegenden Erfindung ist eine Neuerung in dem Aufbau von Filtern und insbesondere von solchen Filtern, in denen sich die Flüssigkeit von unten nach oben bewegt und die geklärte Flüssigkeit oben abgezogen wird. Für solche Filter hat man bisher im wesentlichen als Filtermaterial Asbest-, Zellstoffmaterial usw. zwischen Sieben gelagert angewandt. Ein derartiges Material setzt sich sehr leicht zu. Auch ist die Reinigung bei öligen oder alkalischen Flüssigkeiten recht schwierig, zumal beispielsweise die letzteren sowohl bei Asbest wie auch bei Zellstoff Quellungszustände herbeiführen. The subject of the present invention is an innovation in the structure of filters and especially of those filters in which the liquid is moved from bottom to top and the clarified liquid is drawn off at the top. For Such filters have hitherto been used essentially as filter material asbestos and cellulose material etc. stored between sieves applied. Such a material settles a lot easy to. Cleaning is also fine with oily or alkaline liquids difficult, especially for the latter, for example, with both asbestos and pulp Bring about states of swelling.

Es wurde nun gefunden, daß sich derartige Filterschichten in günstiger AVeise herstellen lassen, wenn man Schwammgummistücke verwendet. Man kann dieses Filtermaterial in iihnlicher Weise, wie dies mit anderem Filtermaterial hisher geschah, zwischen Sieben einschließen oder frei auf der zu filtrierenden oder zu klärenden Flüssigkeit schwimmen lassen. Schwammgummi schwimmt ähnlich wie ein Eisstück. Es ragt nur ein kleiner Teil aus der Flüssigkeit heraus, während der größere Teil unterhalb des Flüssigkeitsspiegels treibt. Sie bieten eine besonders große Filteroberfläche und nur einen verschwindend kleinen Abflußwiderstand. It has now been found that such filter layers are cheaper Have a method made when using pieces of sponge rubber. You can do this Filter material in a similar way as it was done with other filter material up to now, Enclose between sieves or freely on the one to be filtered or clarified Let the liquid swim. Sponge rubber floats like a piece of ice. It only a small part protrudes from the liquid, while the larger part protrudes below the liquid level drifts. They offer a particularly large filter surface and only a negligibly small drainage resistance.

Die Dicke der aufzugebenden Schwamm gummischicht richtet sich je nach der Feinheit des zurückzuhaltenden Materials. Öliger und fettiger Schlamm wird von Schwammgummistücken leichter als von Asbest- oder Zellstoffasern zurückgehalten. Dabei neigen bchwammgummifilter weniger zur Verstopfung und Verfilzung wie Asbest- oder Zellstoffilter. Der Schwammgummi läßt sich nach dem Vollsaugen mit öligem Schlamm leicht mit alkalischen Laugen auskochen und zeigt selbst gegenüber hohen Alkalikonzentrationen keine Quellungserscheinungen. The thickness of the applied sponge rubber layer depends on it according to the fineness of the material to be retained. Oily and greasy mud becomes More easily retained by pieces of sponge rubber than by asbestos or cellulose fibers. Sponge rubber filters are less prone to clogging and matting than asbestos or pulp filters. The sponge rubber can be soaked with oily mud easy to boil with alkaline lyes and shows itself to high alkali concentrations no swelling.
