Description
Die Erfindung betrifft die neuartige Ausbildung eines selbstreinigenden Spaltfilters. Es ist bekannt, Spaltfilter durch Verwendung von Spiralfedern herzustellen, wobei die Größe des Spaltes durch entsprechende Spannung bestimmt wird. The invention relates to the novel design of a self-cleaning Slit filter. It is known to manufacture edge filters by using coil springs, the size of the gap being determined by the corresponding voltage.
-Der Erfindungsgedanke geht ebenfalls davon aus, als Filterkörper Spiralfedern zu verwenden. -The idea of the invention is also based on the filter body Use coil springs.
Durch die neuartige Anordnung derselben wird ein selbstreinigendes Filter geschaffen, bei welchem die Verunreinigungen von den Spaltflächen durch den zu filternden Flüssigkeitsstrom dauernd weggespült werden, ohne.daß dadurch ein Flüssigkeitsverlust auftritt.The new arrangement of the same becomes a self-cleaning one Filter created, in which the impurities from the gap surfaces through the to be filtered liquid flow are continuously washed away, without Fluid loss occurs.
Erfindungsgemäß wird dies dadurch erreicht, daß der eintretende Flüssigkeitsstrom die als Filter dienende Spiralfeder von innen nach außen durchströmt, wobei die Feder entspannt ist, während der austretende Flüssigkeitsstrom die Feder von außen nach innen durchströmt, wobei die Feder gespannt ist. Durch eine entsprechende Ausbildung des Filtergehäuses und eine zweckmäßige Führung des Flüssigkeitsstromes werden die an der Filterfeder abgelagerten Verunreinigungen weggespült und in einem Schlammraum des Filtergehäuses abgelagert, von wo sie von Zeit zu Zeit abgelassen werden können. According to the invention this is achieved in that the incoming liquid flow the spiral spring serving as a filter flows through from the inside to the outside, the The spring is relaxed while the exiting flow of liquid pushes the spring from the outside flows through inwards, the spring being tensioned. Through appropriate training of the filter housing and an appropriate guidance of the liquid flow are the Impurities deposited on the filter spring are washed away and placed in a sludge chamber of the filter housing from where they can be drained from time to time.
Auf diese Weise können auch stark verunreinigte Flüssigkeiten gereinigt werden, ohne daß ein Zusetzen des Filters eintritt oder ein dauernder Flüssigkeitsverlust entsteht. In this way, even heavily contaminated liquids can be cleaned without clogging of the filter or permanent loss of fluid arises.
Ein Ausführungsbeispiel eines solchen Filters ist in den Fig. I, 2 und 3 dargestellt. An embodiment of such a filter is shown in FIGS. 2 and 3 shown.
Fig. I zeigt den Längsschnitt durch das Filter, Fig. 2 einen Querschnitt und Fig. 3 die Ansicht von unten gegen das Filtergehäuse. Fig. I shows the longitudinal section through the filter, Fig. 2 shows a cross section and FIG. 3 shows the view from below against the filter housing.
In den Figuren bedeutet: I das Filtergehäuse, 2 die Eintrittsöffnung, 3 die Austrittsöffnung, 4 die Spiralfedern, 5 die unteren Federteller, 6 das Gehäuseunterteil, 7 ein drehbares oberes Bodenstück, in welches die Federn 4 eingesetzt sind, 8 eine Führungskurve, die in dem unteren Bodenstück 9 angeordnet ist, IO Stößel, die auf dieser Führungskurve gleiten und die Federn heben und senken, Ii die Antriebswelle, die mit einem Antriebsmechanismus beliebiger Art verbunden sein kann; I2 ist der Verbindungskanal mit der Austrittsöffnung 3, I3 die Verbindungsbohrung mit der Eintrittsöffnung 2. In the figures: I means the filter housing, 2 the inlet opening, 3 the outlet opening, 4 the spiral springs, 5 the lower spring plate, 6 the lower part of the housing, 7 a rotatable upper base piece in which the springs 4 are inserted, 8 a Guide curve, which is arranged in the lower base piece 9, IO plunger, which on slide along this guide curve and raise and lower the springs, ii the drive shaft, which can be connected to any type of drive mechanism; I2 is the one Connection channel with the outlet opening 3, I3 the connecting hole with the inlet opening 2.
Die Wirkungsweise des Filters ist folgende: Wie in Fig. 1 ersichtlich, ist diejenige Feder, welche sich unter der Eintritts öffnung 2 befindet, mit ihrem Stößel 10 auf dem tiefsten Punkt der I(urve 8, sie ist also entspannt. Dire einströmende, zu filternde Flüssigkeit strömt durch das Innere der Feder und spült die in den Federwindungen haftenden Schmutzteilchen ab, so daß diese in das untere Gehäuseteil des Filters gelangen. Die zu filternde Flüssigkeit strömt von außen nach innen durch die anderen Filterfedern und über den Verbindungskanal I2 in die Austrittsöffnung 3. Alle Schmutzteilchen werden infolgedessen an den äußeren Windungen der im Spannungszustand befindlichen Federn abgelagert und damit die Filterung der Flüssigkeit erreicht. In gewissen Zeitabständen wird nun durch Drehen der Antriebswelle II eine andere Feder in die Stellung unter den Verbindungskanal 12 gebracht, während die vorher dort befindliche Feder sich von diesem Punkt ,entfernt. Gleichzeitig wird der Stößel entlang der KurveS in die Spannstellung gebracht, so daß die unter Verbindungskanal 12 befindliche Fedler nunmehr wiederum als Spaltfilter wirkt. Der Spülvorgang wiederholt sich jedesmal, wenn eine Feder unter den Verbindungskanal I3 gelangt, und auf diese Weise wird ständig eine Reinigung der Filterfedern von Verunreinigungen herbeigeführt, ohne daß die Filterarbeit unterbrochen wird und Spülflüssigkeit abgelassen werden muß. Es genügt vielmehr, wenn von Zeit zu Zeit der Schmutz, welcher sich in dem Gehäuseteil 6 befindet, abgelassen wird. The operation of the filter is as follows: As can be seen in Fig. 1, is that spring, which is located under the inlet opening 2, with her Plunger 10 at the lowest point of the I (curve 8, so it is relaxed. Dire inflowing, The liquid to be filtered flows through the interior of the spring and flushes it into the Spring coils adhere dirt particles, so that these in the lower housing part of the filter. The liquid to be filtered flows through from the outside to the inside the other filter springs and via the connecting channel I2 into the outlet opening 3. As a result, all dirt particles are in the state of tension on the outer windings The springs are deposited and the liquid is filtered. At certain time intervals the drive shaft II is turned to a different one Spring brought into position under the connecting channel 12, while the previously The spring located there moves away from this point. At the same time the ram brought into the clamping position along the curve S, so that the connecting channel 12 located Fedler now again acts as a slit filter. The rinsing process repeats every time a spring gets under the connecting channel I3, and on this In this way, the filter springs are constantly cleaned of impurities, without the filter work being interrupted and flushing liquid being drained off got to. Rather, it is sufficient if from time to time the dirt that is in the Housing part 6 is located, is drained.
