Description

Filtervorrichtung- für Flüssigkeiten Die Erfindung betrifft eine Flüssigkeitsfiltervorrichtung, bei der in einem Behälter ein doppelwandiger, hohlzylinder- oder kegelförmiger Siebbehälter für das Filtermaterial vorgesehen ist.Filter device for liquids The invention relates to a liquid filter device, with a double-walled, hollow cylinder or conical sieve container in one container is provided for the filter material.

Bei den bekannten Filtervorrichtungen dieser Art ordnete man tangential zur Gehäuseachse in den Behälter einmündende Zuflußstutzen stets in Höhe des Filterkörpers an und unterstützte die Abscheidung der festen Stoffe aus der Flüssigkeit sowie Befreiung der Filterkörperwandungen von Ablagerungen durch rotierende Rührwerke oder Schaber. The known filter devices of this type were arranged tangentially Inflow nozzles opening into the container towards the axis of the housing are always at the height of the filter body and supported the separation of solids from the liquid as well Removal of deposits from the filter body walls using rotating agitators or scraper.

Die Erfindung besteht nun darin, daß der tangentiale Rohflüssigkeitseinlaß in einen völlig freien Raum unterhalb des Filterkörpers einmündet. Es bildet sich hierdurch in dem von dem hohlzylinderförmigen Filterbehälter umgebenen Rohflüssigkeitsraum ein sehr starker Flüssigkeitswirbel, der die Hauptmenge der Feststoffe in sich aufnimmt und gleichzeitig Ablagerungen an den Filterkorbwandungen verhindert. Es kommen dadurch die den Betrieb und die Herstellungskosten von Filtervorrichtungen sehr verteuernden Rührwerke, Schaber u. dgl. in Wegfall. The invention consists in that the tangential raw liquid inlet opens into a completely free space below the filter body. It forms as a result, in the raw liquid space surrounded by the hollow cylindrical filter container a very strong fluid vortex that absorbs most of the solids and at the same time prevents deposits on the filter basket walls. It comes through it which make the operation and manufacturing costs of filter devices very expensive Agitators, scrapers and the like are no longer necessary.

Der Erfindungsgegenstand ist in der Zeichnung in zwei beispielsweisen Ausführungsformen veranschaulicht, und zwar zeigt Abb. 1 einen Gesamtlängsschnitt durch die Filtervorrichtung, Abb. 2 einen Grundriß der Abb. 1 und Abb. 3 eine weitere Ausführungsform im Schnitt. The subject of the invention is shown in two examples in the drawing Embodiments illustrated, namely Fig. 1 shows an overall longitudinal section through the filter device, Fig. 2 is a plan view of Fig. 1 and Fig. 3 is another Embodiment in section.

In einem Gehäuse G ist der Aufnahmebehälter B für das aus Kies, Asbestfäden, Torffäden oder anderem geeigneten Material bestehende Filtermaterial fest oder herausnehmbar angeordnet. Im vorliegenden Falle ist der Filterraum B von einem mit siebartigen Öffnungen versehenen kegelförmigen (Abb. I) oder zylinderförmigen (Abb. 3) Außenmantel M und einem mittels Spindel bewegbaren perforierten kegel- oder zylinderförmigen Innenmantel S begrenzt. Oben schließt sich an den Filterraum B ein Fülltrichter T an (Abb. 1). Der untere Abschluß des Filterraums B wird durch einen am versenkbaren Innensieb S befestigten schrägen Boden O bewirkt. Durch Senken des Siebkegeis S gelangt die Füllung bei gleichzeitiger Verteilung durch die Schlitze Sch im Bodens in den Absitzraum R und von dort durch das Ventil K nach außen, während gleichzeitig in an sich bekannter Weise neues Filtermaterial aus dem Fülltrichter T selbsttätig in den Raums nachrutscht. Es ist somit ohne Unterbrechung der Filtration eine je nach Bedarf periodische Erneuerung des losen Filtermaterials möglich. In a housing G is the receptacle B for the gravel, asbestos threads, Peat threads or other suitable material existing filter material fixed or removable arranged. In the present case, the filter space B is a sieve-like one Openings provided conical (Fig. I) or cylindrical (Fig. 3) outer jacket M and a perforated conical or cylindrical shape movable by means of a spindle Inner jacket S limited. At the top of the filter space B is a filling funnel T on (Fig. 1). The lower end of the filter space B is retractable by a Inner sieve S attached inclined bottom O causes. By lowering the sieve cone S the filling arrives at the same time as it is distributed through the slots Sch in the bottom into the sitting room R and from there through the valve K to the outside, while at the same time in a manner known per se new filter material from the hopper T automatically slides into the room. It is thus one each without interrupting the filtration Periodic renewal of the loose filter material is possible as required.

In den völlig freien Raum R zwischen der Filtermaterialkammer B und SchlammablaD K mündet der Einlaß E tangential zur Gehäuse achse ein. Der sich hierbei im Raum R bildende Flüssigkeitswirbel nimmt die Hauptmenge der Feststoffe bereits vor der Berührung mit den Filterkörperwandungen in sich auf und verdichtet sie. Diese Verdichtung der durch Filter schwer ausscheidbaren, kolloiden, elektrisch aufgeladenen Trübungen im Wirbelraum R erfolgt dadurch, daß dort unter dem Einfluß der auftretenden Zentripetalkräfte eine Entladung, d. h. eine Verdichtung kolloider Teilchen durch Oberflächenwirkung und Okklusion, an jene gröberen Sink- und Schwebstoffe vor sich geht, die erfahrungsmäßig stets dem größeren Strome auszuweichen versuchen und der Stromachse des Wirbels zustreben, wobei sie ihre elektrische Aufladung verlieren und durch entgegengesetzte Aufladung zur Koagulation, d. h. zur Verdickung, gebracht werden. Hierdurch werden vorwiegend die schwer filtrierbaren Schwebstoffe kolloider Art aus dem Rohflüssigkeitsstrom entfernt, und zwar bevor dieser das Filtermedium passiert hat. In the completely free space R between the filter material chamber B and SchlammablaD K opens into inlet E tangential to the housing axis. The here Liquid eddies forming in space R take up the bulk of the volume the Solids on and before contact with the filter body walls condenses them. This compression of the colloidal, Electrically charged opacities in the vortex space R takes place in that there under the influence of the occurring centripetal forces a discharge, d. H. a compression colloid particles through surface action and occlusion, to those coarser sinking and suspended matter is going on, which experience shows always to avoid the larger stream try and strive for the current axis of the vortex, taking their electrical charge lose and due to opposite charging to coagulation, d. H. for thickening, to be brought. This mainly removes suspended matter that is difficult to filter colloidal type is removed from the raw liquid flow before the filter medium is removed happened.

Durch die Rotation der Flüssigkeit im Innern des Siebmantels S werden gleichzeitig die aus der Flüssigkeit abgesonderten Sinkstoffe von der Filterwand dauernd selbsttätig abgehalten. Die kegelförmige Form des Siebmantels S hat hierbei noch den besonderen Vorteil, daß die Wirbelung auch mit annähernd gleieher Drehzahl bis in die Spitze hineinreicht, während bei zylindrischen Sieb. mänteln die Wirbelung oben entsprechend der durch die Wand strömenden Flüssigkeit nachläßt. As a result of the rotation of the liquid inside the sieve jacket S become at the same time the suspended matter separated from the liquid from the filter wall held continuously automatically. The conical shape of the screen jacket S has here still the special advantage that the vortex can also be operated at approximately the same speed extends to the tip, while with a cylindrical sieve. coat the vortex decreases at the top according to the liquid flowing through the wall.

Die gereinigte Flüssigkeit verläßt bei A das Gehäuse. Der Spülversatz erfolgt einmal durch die rotierende Bewegung der Flüssigkeit längs der Filterwand und dann beim periodischen Ablassen des Schlammes durch öffnen des Klotzventils f (. Zum Rückspülen wird Filtrat benutzt. Der innere Siebmantel S muß stets unter dem niedrigsten Flüssigkeitsstand liegen. The cleaned liquid leaves the housing at A. The flush offset occurs once through the rotating movement of the liquid along the filter wall and then with the periodic drainage of the sludge by opening the pad valve f (. Filtrate is used for backwashing. The inner sieve jacket S must always be under the lowest fluid level.
