Die abzuscheidende Flüssigkeit dringt durch die rotationskörperförmigen Filtrationsflächen und wird als Filtrat mittels jeweils eines an den Filtrationsflächen angeschlossenen Filtratsabflusses abgeführt Das in der Filtrationskammer übriggebliebene Produkt bewegt sich durch die Filtrationskammer in Richtung zu einem Produktauslass, durch welchen das Produkt den Filtrationsapparat verlässt. Der Filtrationsapparat arbeitet also kontinuierlich mit einem ständigen Durchfluss der Suspension bzw. des Produkts zwischen den die Filtrationskammer bildenden Filtrationsflächen.In the case of the filtration apparatus of this type, the one to be treated is carried out pressurized suspension through a suspension inlet into an annular one Filtration chamber. The liquid to be separated penetrates through the rotational body-shaped Filtration surfaces and is used as a filtrate by means of one on each of the filtration surfaces connected filtrate drain drained away The leftover in the filtration chamber Product moves through the filtration chamber towards a product outlet, through which the product leaves the filtration apparatus. The filtration apparatus works continuously with a constant flow the Suspension or the product between the filtration surfaces forming the filtration chamber.

Jedoch bei manchen zu behandelnden Suspensionen bildet sich an den Filtrationsflächen eine feste Kuchenschicht und der bekannte Filtrationsapparat ist zum Filtrieren einer solchen Suspension dann nicht geeignet.However, in some of the suspensions to be treated, the Filtration surfaces a solid cake layer and the well-known filtration apparatus is then not suitable for filtering such a suspension.

Es ist die Aufgabe dieser Erfindung, einen Filtrationsapparat zu schaffen, bei welchem die Bildung einer festen Kuchenschicht an den Filtrationsflächen verhindert wird.It is the object of this invention to provide a filtration apparatus, which prevents the formation of a solid cake layer on the filtration surfaces will.

Diese Aufgabe ist an einem Filtrationsapparat der eingangs beschriebenen Art dadurch gelöst, dass in der ringfömrigen Filtrationskammer eine rotierende Misch-Rühr-Vorrichtung angeordnet ist.On a filtration apparatus, this task is the same as that described at the outset Art solved in that a rotating mixing-stirring device in the annular filtration chamber is arranged.

Nach einer bevorzugten Ausführungsform weist die rotierende Misch-Rühr-Vorrichtung in der Filtrationskammer eine Anzahl von Stäben auf, welche gemeinsam ein rotationskörperförmiges Stabgitter bilden. Durch Drehen dieses Stabgitters- in der Filtrationskammer wird das Produkt nicht nur turbulent tangential gemischt und gerührt, sondern es entstehen dadurch auch in Umfangsrichtung an den Filtrationsflächen wirkende Scherkräfte, so dass sich an den Filtrationsflächen keine Kuchenschicht bilden kann.According to a preferred embodiment, the rotating mixing-stirring device in the filtration chamber on a number of rods, which together form a body of revolution Form bar lattice. By turning this bar grating in the filtration chamber the product is not only mixed and stirred in a turbulent tangential manner, it is created thus also shear forces acting in the circumferential direction on the filtration surfaces, so that no cake layer can form on the filtration surfaces.

Nach einer weiteren bevorzugten Ausführungsform weist die rotierende Misch-Rühr-Vorrichtung eine zwischen den Filtrationsflächen achsparallel zu diesen verlaufende Wand auf, welche einen Rotationskörper bildet und mit Löchern versehen ist. Mit Vorteil ist diese achsparallel verlaufende Wand als ein rauhes Rohr, vorzugsweise mit quer zur Umlaufrichtung angeordneten Rippen zum Fördern des Produkts ausgeführt.According to a further preferred embodiment, the rotating Mixing-stirring device one between the Filtration surfaces parallel to the axis to these extending wall, which forms a body of revolution and with holes is provided. This axially parallel wall is advantageous as a rough one Tube, preferably with ribs arranged transversely to the direction of rotation for conveying the Product executed.

Dabei werden neben dem bisher erreichten Effekt, nämlich neben dem tangentialen Mischen und Rühren und neben den in Umlaufrichtung wirkenden Scherkräften noch zusätzlich in Axialrichtung an den Filtrationsflächen wirkende Scherkräfte herbeigeführt.In addition to the previously achieved effect, namely next to the tangential mixing and stirring and in addition to the shear forces acting in the direction of rotation additional shear forces acting on the filtration surfaces in the axial direction brought about.

Im weiteren wird der Erfindungsgegenstand anhand der Zeichnung näher beschrieben und erklärt. Es zeigen: Fig. 1 ein Ausführungsbeispiel, Fig. 2 ein anderes Ausführungsbeispiel eines Filtrationsapparats jeweils im vertikalen Querschnitt, Fig. 3 verschiedene Profilformen der Stäbe der Misch-RUhr-Vorrichtung, Fig. 4 bis 5 je eine Ausführungsform der Stäbe, und Fig. 6 eine Wand aufweisende Misch-Rühr-Vorrichtung.The subject matter of the invention is further illustrated by means of the drawing described and explained.

Die Filtrationsflächen 3 und 4 sind zylindrisch und zueinander koaxial angeordnet. Eine zu behandelnde Suspension wird unter Druck durch einen Suspensionszulauf 6 in die Filtrationskammer 2 hinein geführt und das Produkt wird aus der Filtrationskammer 2 durch einen Produktauslass 7 weggeführt. An diesem Produktauslass 7 ist ein nicht gezeichnetes Ventil angeordnet, mittels welchem ein Betriebsdruck in der Filtrationskammer 2 einstellbar ist.The filtration apparatus shown in Fig. 1 has a housing 1 an annular filtration chamber 2, which between a rotational body-shaped External filtration surface 3 and a rotational body-shaped nested therein Internal filtration surface 4 is formed. The filtration surfaces 3 and 4 are cylindrical and arranged coaxially to one another. A suspension to be treated is pressurized through a suspension inlet 6 into the filtration chamber 2 guided and the product is led away from the filtration chamber 2 through a product outlet 7. A valve (not shown) is arranged at this product outlet 7, by means of which an operating pressure in the filtration chamber 2 can be set.

Dabei dringt die Flüssigkeit aus der Suspension durch die Filtrationsflächen 3 und 4 jeweils in einen der Fläche angeschlossenen Filtratsabfluss 8 bzw. 9 und wird als Filtrat durch einen Kanal 10 bzw. 11 weggeführt.The liquid penetrates from the suspension through the filtration surfaces 3 and 4 each into a filtrate outflow 8 or 9 and connected to the surface is carried away as a filtrate through a channel 10 or 11.

In der ringförmigen Filtrationskammer 2 ist eine rotierende Misch-Rühr-Vorrichtung 12 angeordnet. Die Misch-Rühr-Vorrichtung 12 weist eine Anzahl von gleichmässig in Umfangsrichtung der Filtrationskammer 2 verteilten Stäben 13 auf. Diese sind in zwei Ringen 14 gehalten und bilden zusammen ein rotationsförmiges, d.h. zylindrisches Stabgitter 15. Der obere Ring 14 in der Fig. 1 ist bei einer Hohlwelle 16 angebracht, welche in einem die Filtrationskammer 2 abschliessenden Deckelteil 17 des Gehäuses 1 drehbar und axial unverschiebbar gelagert und abgedichtet ist.In the annular filtration chamber 2 is a rotating mixing-stirring device 12 arranged. The mixing-stirring device 12 has a number of uniform rods 13 distributed in the circumferential direction of the filtration chamber 2. These are held in two rings 14 and together form a rotational, i.e. cylindrical Bar grid 15. The upper ring 14 in Fig. 1 is attached to a hollow shaft 16, which in a the filtration chamber 2 closing cover part 17 of the housing 1 is rotatably and axially immovable and sealed.

Die Hohlwelle 16 wird mittels eines Motors 18 gedreht, welcher in beiden Richtungen mit Regulierung der Drehzahl drehbar ist. Der Hohlraum der Hohlwelle 16 ist nach aussen mittels eines Deckels 21 abgeschlossen.The hollow shaft 16 is rotated by means of a motor 18, which in is rotatable in both directions with regulation of the speed. The cavity of the hollow shaft 16 is closed to the outside by means of a cover 21.

Die Stäbe 15 sind gerade, glatte und ein rundes Profil aufweisende Stäbe. Dieses Profil ist in einem grösseren Massstab in Fig. 3 unter der Bezeichnung 151 gezeigt.The rods 15 are straight, smooth and have a round profile Bars. This profile is in a bigger one Scale in Fig. 3 below the designation 151 shown.

In dieser Fig. 5 sind auch andere mögliche Profile der Stäbe gezeigt#. So ist ein Quadratprofil mit 152 be-4 zeichnet. Mit 15# und 15 sind Profile mit noch anderen hydraulischen Wirkungen bezeichnet.In this FIG. 5, other possible profiles of the bars are also shown #. A square profile with 152 is labeled 4. With 15 # and 15 are profiles with other hydraulic effects.

Es wäre auch denkbar, nur einen einzigen Stab 13 in der ringförmigen Filtrationskammer 2 umlaufen zu lassen.It would also be conceivable to have only a single rod 13 in the annular To let the filtration chamber 2 circulate.

Die Ringe 14 könnten dann bloss auf Arme zum Halten des einen Stabes reduziert werden.The rings 14 could then only be on arms for holding one rod be reduced.

Die Stäbe 13 könnten auch als Transportschnecken 23, wie in Fig. 5 oder als Rechenstäbe 24, wie in Fig. 4 ausgeführt sein. Solche Stäbe wären dann in den Ringen 14 um ihre Achse herum drehbar gehalten. Zum Drehen der Stäbe um ihre Achse herum ist es vorteilhaft, einen Planetenantrieb mit Planetenrädern 25 an den Stäben, welche mit einem stehenden Sonnenrad 26 zusammenwirken, vorzusehen.The rods 13 could also be used as screw conveyors 23, as in FIG. 5 or as rake bars 24, as shown in FIG. 4. Such bars would then be held in the rings 14 rotatably about their axis. To rotate the rods around hers Axis around it is advantageous to have a planetary drive with planetary gears 25 to the Rods which cooperate with a stationary sun gear 26 are to be provided.

Die zylindrisch#Filtrationsflächen 5 und 4 sind in dem Gehäuse 1 drehbar angeordnet, und werden mittels eines Motors 50 bzw. eines Motors 52 angetrieben.The cylindrical filtration surfaces 5 and 4 are rotatable in the housing 1 arranged, and are driven by means of a motor 50 and a motor 52, respectively.

Es ist dadurch möglich, dass sie beim Filtrieren stehenbleiben oder nötigenfalls in Bewegung gebracht werden können.It is therefore possible that they stop or when they are filtered can be set in motion if necessary.

Bei dem Filtrationsapparat nach Fig. 2 ist die Misch-Rühr-Vorrichtung 12 zu der ringförmigen Filtrationskammer 2 exzentrisch angeordnet und planetenartig rotierend ausgeführt. Die Filtrationskammer 2 ist mit einer zu ihr konzentrisch angeordneten Scheibe 35 abgeschlossen. Die Scheibe 35 ist in dem Gehäuse 1 drehbar und axial unverschiebbar gelagert und abgedichtet.In the filtration apparatus of Fig. 2, the mixing-stirring device is 12 arranged eccentrically to the annular filtration chamber 2 and like a planet rotating executed. The filtration chamber 2 is arranged with a concentric to it Disc 35 completed. The disk 35 is rotatable and axial in the housing 1 immovably mounted and sealed.

Eine Welle 36 der Misch-Rühr-Vorrichtung 12 ist in der Scheibe 35 exzentrisch zu ihr drehbar und axial unverschiebbar gelagert und abgedichtet. Zum Drehen der Scheibe 35 ist ein Motor 37 vorgesehen, welcher in beiden Richtungen mit Regulierung der-Drehzahl drehbar ist. Zum Drehen der Misch-Rühr-Vorrichtung 12 um ihre Achse herum ist ein Planetengetriebe vorgesehen.A shaft 36 of the mixing-stirring device 12 is in the disk 35 eccentrically to it rotatable and axially immovable mounted and sealed. To the Rotating the disc 35, a motor 37 is provided which operates in both directions is rotatable with regulation of the speed. For turning the mixing-stirring device A planetary gear is provided around its axis.

Dieses weist ein Planetenrad 38, welches an der Welle 36 der Misch-Rühr-Vorrichtung angekeilt ist und ein stehendes Sonnenrad 39 auf.This has a planet gear 38 which is attached to the shaft 36 of the mixing-stirring device is wedged and a stationary sun gear 39.

Die rotierende Misch-Rühr-Vorrichtung 12 weist eine zwischen den Filtrationsflächen 3 und 4 achsparallel zu diesen verlaufende rotationskörperförmige Wand 41 auf, welche einen Rotationskörper nämlich einen Zylinder bildet. Die Wand 41 ist mit Löchern 42 versehen, damit das Produkt durch die Wand 41 durchdringen kann. Aus demselben Grund ist auch ein die Wand 41 haltender Ring 14 mit Löchern 22 versehen.The rotating mixing-stirring device 12 has one between the filtration surfaces 3 and 4 axially parallel to these extending rotational body-shaped wall 41, which namely, a body of revolution forms a cylinder. The wall 41 is with holes 42 provided so that the product can penetrate through the wall 41. From the same A ring 14 holding the wall 41 is also provided with holes 22.

Die achsparallel zur Filtrationskammer 2 verlaufende Wand 41 ist als ein beiderseits rauhes Rohr ausgeführt und vorzugsweise weist die Wand 41 quer zur Umlaufrichtung verlaufende Rippen 43 auf. Wie es besonders gut in Fig.6 zu sehen ist, verlaufen die Rippen jeweils entlang einer gedachten Schraubenlinie, und helfen so das Produkt auch in Richtung zum Produktablass 7 zu bewegen.The axially parallel to the filtration chamber 2 wall 41 is as a pipe rough on both sides and preferably has the wall 41 transversely to Ribs 43 running in the circumferential direction. As can be seen particularly well in Fig. 6 is, the ribs each run along an imaginary helical line, and help so to move the product also in the direction of the product outlet 7.

Die beiden Filtrationsflächen 3 und 4 sind im Gehäuse 1 feststehend angeordnet.The two filtration surfaces 3 and 4 are stationary in the housing 1 arranged.

Der erfindungsgemässe Filtrationsapparat arbeitet grundsätzlich in allen Lagen im Raum. Die dargestellte vertikale Anordnung im Raum ist jedoch eine der platzsparensten.The filtration apparatus according to the invention basically works in all positions in the room. However, the illustrated vertical arrangement in space is one the most space-saving.
