Zum Reinigen von Flüssigkeiten von darin aufgeschwemmten festen Stoffen hat man bereits Zentrifugalfilter benutzt, die aus drehbaren Trommeln bestehen, deren Filterflächen durch schraubenartig gewundene Abstreicher von dem angesetzten Filterschlamm gereinigt werden können; diese Filter können so beschaffen sein, daß die zu filtrierende Flüssigkeit aus dem Innern der Trommel durch derenTo clean liquids from solids suspended in them, one has already Centrifugal filters used, which consist of rotating drums, whose filter surfaces cleaned of the applied filter sludge by means of a screw-like wound scraper can be; these filters can be designed so that the liquid to be filtered from inside the drum through their

ίο Wandung nach außen tritt oder umgekehrt. Ferner hat man auch zum Filtrieren von Bier u. dgl. Filter vorgeschlagen, die aus einem hängenden, teilweise gelochten Doppelzylinder bestehen und bei denen die filtrierte Flüssigkeit durch beide Zylinderwände austritt.ίο Wall steps outwards or vice versa. Furthermore, it has also been proposed for filtering beer and the like. Filters that consist of a hanging, partially perforated double cylinders consist and in which the filtered liquid exits through both cylinder walls.

Zur sachgemäßen Behandlung keramischer und ähnlicher breiartiger. Massen eignen sich nun aber die bekannten Filter nicht gut, da die keramischen Massen möglichst gründlich und gleichmäßig vom Wasser befreit und durchgearbeitet werden sollen. Eine zur Behandlung keramischer Massen besonders geeignete Filterpresse zu schaffen ist nun Zweck der vorliegenden Erfindung, und die Aufgabe ist dadurch gelöst^worden, daß zur Aufnahme der zu . filtrierenden Masse ein von zwei konzentrischen feststehenden Siebzylindern gebildeter Ringraum dient, in dem zwei zueinander konzentrische Schnecken angeordnet sind, die so zusammen arbeiten, daß die eine das Filtergut längs des einen Siebzylinders bewegt, während die andere es an dem zweiten Siebzylinder vorüberführt, so daß also ein geschlossener Kreislauf innerhalb der Presse stattfinden kann.For the proper treatment of ceramic and similar pulpy. Crowds are suitable But now the known filters are not good, because the ceramic masses are as thorough as possible and should be freed from the water evenly and worked through. One for treatment It is the purpose of the present invention to create filter presses that are particularly suitable for ceramic masses, and the object is thereby resolved ^ that to accommodate the too. filtering mass one of two concentric stationary screen cylinders formed annular space is used in which two concentric to each other Screws are arranged which work together so that one of the filter material moved along the one screen cylinder while the other moves it past the second screen cylinder, so that a closed cycle can take place within the press.

Eine solche Filterpresse ermöglicht eine sehr gründliche Ausscheidung des Wassers aus keramischen Massen und liefert ein durchweg homogenes, zur späteren Verarbeitung sehr geeignetes Material.Such a filter press enables a very thorough separation of the water from ceramic Masses and delivers a consistently homogeneous material that is very suitable for later processing.

Auf der Zeichnung ist eine Ausführungsform der neuen Filterpresse im Längsschnitt ver-· anschaulicht.The drawing shows an embodiment of the new filter press in longitudinal section. illustrative.

Die Filterpresse besitzt zwei konzentrisch zueinander und unbeweglich angeordnete Siebzylinder 3, 4, die mit Filtertuch bespannt sein können. Zwischen den beiden Zylindern befinden sich zwei Förderschnecken 5, 51, deren einzelne Gänge durch Versteifungen 6 miteinander verbunden sind.The filter press has two screen cylinders 3, 4 which are concentric with one another and are immovable and which can be covered with filter cloth. Between the two cylinders there are two screw conveyors 5, 5 1 , the individual flights of which are connected to one another by stiffeners 6.

Die beiden Schnecken werden von einer Scheibe 8 getragen, die mittels einer zu den Siebzylindern konzentrischen Welle in Umdrehung versetzt werden kann. Sie stehen sich so gegenüber, daß das Filtergut am äußeren Filter entlang in den Ringraum zwischen den beiden Siebzylindern eingeführt und am inneren entlang wieder nach außen befördert wird. Bei dieser Anordnung kann also die zu filtrierende Masse bei geschlossenem Austritt in Kreislauf versetzt werden, bis sie gehörig vom Wasser befreit ist.The two screws are carried by a disc 8, which by means of a to the Sieve cylinders concentric shaft can be set in rotation. You stand yourself so opposite that the filter material along the outer filter in the annular space between the two screen cylinders is introduced and conveyed along the inner back to the outside. In this arrangement, the mass to be filtered can be filtered with the outlet closed in Circulation can be shifted until it is properly freed from water.

Um den Umlauf der Masse zu sichern, empfiehlt es sich, zwischen den beiden Schnecken 5,51 einen Trennungszylinder 9 anzuordnen, der entweder gleich den Schnecken an der Scheibe 8 befestigt sein und mit ihnen umlaufen kann oder einfach lose zwischen den Schnecken liegt.In order to ensure the circulation of the mass, it is advisable to arrange a separation cylinder 9 between the two screws 5, 5 1 , which can either be attached to the disk 8 like the screws and rotate with them or simply lies loosely between the screws.
