PATENTAMT.PATENT OFFICE.
Die bisher im Gebrauch befindlichen Filter bedienen sich zum Zweck der. Reinigung zumeist mechanischer Rührwerke, . welche die Filtermaterialien aufrühren und unter Wasserzufuhr auswaschen. Diesen Einrichtungen haften Mängel an. Erstens ist der Verbrauch an Waschflüssigkeit groß, und zweitens ist diese Art der Auswaschung zumeist nur bei Filtermaterialien von körniger oder sandiger Beschaffenheit anwendbar.The filters currently in use are used for the purpose of. Cleaning mostly mechanical agitators,. those who Stir filter materials and wash out under water. These facilities there are defects. First, the consumption of washing liquid is great, and second, it is Type of leaching mostly only with filter materials of a granular or sandy nature applicable.
Für Filtermaterialien von leicht zerstörbarer langfaseriger oder wolliger Beschaffenheit ist die bisherige Art der mechanischen Reinigung nicht anwendbar.For filter materials that are easily destructible, long-fiber or woolly the previous type of mechanical cleaning cannot be used.
Gegenstand der Erfindung ist nun ein Verfahren zur Reinigung von Filtern, bei wel-. chen ■ das Filtermaterial in bekannter Weise in einem mit Siebböden versehenen, in einer Ummantelung kolbenartig hin und her bewegbaren Zylinder untergebracht ist, und zwar besteht das Verfahren darin, daß zwecks Reinigung des Filtermaterials beim Auf- und Niedergang des mit dem Filtermaterial gefüllten Zylinders die Waschflüssigkeit angesaugt, entgegengesetzt der Filtrationsrichtung von unten nach oben durch das Filtermaterial stoßweise hindurchgeführt wird und die Verunreinigungen nach oben abgeführt werden.The invention now relates to a method for cleaning filters in which wel-. Chen ■ the filter material in a known manner in a provided with sieve trays, in a Sheath is housed piston-like reciprocating cylinder, namely The method consists in that for the purpose of cleaning the filter material when rising and falling of the cylinder filled with the filter material, the washing liquid is sucked in, opposite the direction of filtration from bottom to top is passed through the filter material intermittently and the impurities be discharged upwards.
Die zur Ausführung des Verfahrens dienende Vorrichtung ist auf der Zeichnung in einem Vertikalschnitt durch das Filter veranschaulicht. Die Filtermaterialien beliebiger Art befinden sich in einem geschlossenen Zylinder a, dessen oberer und unterer Boden b und c gelocht sind. Der Zylinder a mit Filtermaterial wird zum Zweck der Reinigung in einer geschlossenen Ummantelung d nach Art eines Pumpenkolbens aufwärts und abwärts bewegt, wobei durch an der Ummantelung d angeordnete Saugventile oder Klappen e die Waschflüssigkeit zunächst beim Hochgang angesaugt, beim Niedergang darauf durch das Filtermaterial in α hindurchgepreßt und beim folgenden Hochgang schließlich durch an der Ummantelung d angeordnete Druckventile oder Klappen f nach außen gepreßt wird. Die Waschflüssigkeit wird dem Saugventil e der Ummantelung unter so hohem Druck zugeführt, daß das Saugventil in dem Maße entlastet ist, daß ein Rückströmen der Waschflüssigkeit durch die Filtermaterialien im Zylinder a in gewünschtem Grade vermieden wird. Durch die Abdichtung g wird die Ummantelung d in Saug- und Druckraum getrennt. Der Zylinder α wird durch bekannte, an der Spindel h angreifende Organe, z. B. Kurbelwelle, Exzenter, Zahngetriebe, auf- und abwärts bewegt. Das Eigengewicht des Zylinders α zuzüglich des Gewichtes der Filtermaterialien wird durch auf der Kurbel- oder Exzenterwelle aufgekeilte Schwungräder ausgeglichen, so daß nur der Durchflußwiderstand zu überwinden ist.The device used to carry out the method is illustrated in the drawing in a vertical section through the filter. The filter materials of any type are located in a closed cylinder a, the upper and lower bases b and c of which are perforated. The cylinder a with filter material is moved up and down for the purpose of cleaning in a closed casing d in the manner of a pump piston, with suction valves or flaps e arranged on the casing d initially sucking in the washing liquid when going up, then through the filter material in α when going down pressed through and finally pressed outwards through pressure valves or flaps f arranged on the casing d during the following upstroke. The washing liquid is fed to the suction valve e of the casing under such high pressure that the suction valve is relieved to the extent that a backflow of the washing liquid through the filter materials in the cylinder a is avoided to the desired extent. The casing d is separated into the suction and pressure chamber by the seal g. The cylinder α is by known, acting on the spindle h organs, for. B. crankshaft, eccentric, toothed gear, moves up and down. The weight of the cylinder α plus the weight of the filter materials is balanced by flywheels keyed onto the crankshaft or eccentric shaft, so that only the flow resistance has to be overcome.
Am Mantel d sind radial Führungsrädchen i angeordnet, welche auf am Zylinder a angebrachten Leisten laufen, um ein Schwingen des Zylinders α nebst Inhalt während seiner Auf- und Abwärtsbewegung zu vermeiden. Beim Betriebe des Filters wird die zu filtrierende Flüssigkeit durch den Zylinder α geleitet.Radial guide wheels i are arranged on the jacket d , which run on bars attached to the cylinder a in order to prevent the cylinder α and its contents from swinging during its upward and downward movement. When the filter is in operation, the liquid to be filtered is passed through the cylinder α .
k ist der Eintrittsstutzen für die zu filtrierende Flüssigkeit, I deren Austrittsstutzen, m eine weitere Ablaß vorrichtung, um das Filter leer laufen zu lassen. Während der Filtration befindet sich der Zylinder a in Ruhe, die Absperrorgane η und ο vor dem Saug- und Druckventil sind geschlossen. k is the inlet nozzle for the liquid to be filtered, I its outlet nozzle, m another drain device to allow the filter to run empty. During the filtration, the cylinder a is at rest, the shut-off devices η and ο in front of the suction and pressure valve are closed.
