Abstract
Description
Die Drfindung betrifft ein Drehfilter nach dem Oberbegriff des Anspruchs 1. Bei bekannten Drehfiltern befindet sich die Lagerung der Welle unmittelbar an den Stirnwänden des Troges, wobei zwecks Abdichtung Stopfbüchsen oder andere Dichtungsanordiiungen vorgesehen sind. Derartige Dichtungsanordnungen sind nicht nur aufwendig, sondern auch dem Verschleiß unterworfen und müssen dementsprechendThe invention relates to a rotary filter according to the preamble of the claim 1. In known rotary filters, the bearing of the shaft is directly on the end walls of the trough, with stuffing boxes or other sealing arrangements for the purpose of sealing are provided. Such sealing arrangements are not only expensive, but also also subject to wear and tear and must accordingly
in zeitlichen Abständen ausgewechselt werden, Ferner werden die im Bereich der Dichtungsanordnungen liegenden Wellen stark eingeschnürt, was nicht nur zu höheren Antriebsleistungen führt, sondern auch zu Verschleißerscheinungen auf der Welle selbst, so daß die Dichtungsanordnungen nicht einwandfrei auf der Welle sitzell. Letztere geben somit Anlaß zu Ärger und Betriebsstörungen, wenn sie nicht für genügende Abdichtung sorgen.be replaced at regular intervals. Furthermore, the im Waves lying in the area of the sealing arrangements are strongly constricted, which is not only leads to higher drive power, but also to signs of wear on the shaft itself, so that the sealing arrangements are not properly on the Shaft Sitzell. The latter give rise to anger and breakdowns when they do not provide sufficient sealing.
Der Erfindung lie-gt die Aufgabe zugrunde, die genannten Nachteile set eher Dichtungsancrdnungen zu vermeiden und wolle dieselben auszukommen.The invention is based on the stated disadvantages set rather to avoid sealing conditions and want to get along with the same.
Die Aufgabe wird erfindungsgemäß durch die Maßnahmen nach dem kennzeichen des Anspruchs l gelöst, Es wird somit bewußt eine geringfügige Leckage herbeigeführt, weil dabei jegliche Dichtungsanordnung an den Wellenenden entfallen kann, somit auch jeder Verschleiß des Dichtmittels und der Welle0 Diese Vorteile überwiegen den lediglich einmal bei der Herstellung auftretenden Aufwand, der darin besteht, die Welle um ein geringes Maß zu verlängern. Die durch die Öffnungen in kleiner Menge fließende Suspension strömt bei tiefer liegendem Sammelbehälter (für die Suspension) diesem einfach zu und wird bei höher liegendem Sammelbehälter mittels einer Pumpe hinaufgepumpt. Dabei kann die Pumpe bei Erreichen eines bestimmten Suspensionsstandes in einem Sammelraum automatisch einschaltbar sein.The object is achieved according to the invention by the measures according to the mark of claim l solved, it is thus deliberately caused a minor leakage, because any sealing arrangement on the shaft ends can be dispensed with, thus also any wear of the sealant and the shaft0 These advantages outweigh the effort that occurs only once in production, which consists of to lengthen the shaft by a small amount. The through the openings in smaller Amount of flowing suspension flows in the case of a lower-lying collecting container (for the suspension) This is easy to do and is used with a higher-lying collecting container by means of one Pump pumped up. When a certain suspension level is reached, the pump can be switched on automatically in a collecting room.
Aus der DT-AS 12 23 344 ist zwar eine Lagerung der einen Trommelr.lalltel tragenden Welle bekannt, wobei die Lager außerhalb der Stirnwand des Troges angeordnet sind. Diese Anordnung verfolgt jedoch einen anderen Zweck, was allein schon daraus hervorgeht, daß die Abdichtung des Troges gegenüber der Suspension mit den bekannten Di chtungs alle rdiiungen vorgenommen wird Weiterbildungen der Erfindung sind den Unteransprüchen entnehiar. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigen: Fig. 1 das Schema eines Trommelfilters in einem Längsmittelschnitt und Fig. 2 in einer Seitenansicht.From the DT-AS 12 23 344 there is a bearing of one drum r bearing shaft known, with the bearings arranged outside the end wall of the trough are. However, this arrangement has a different purpose, which is evident from that it can be seen that the sealing of the trough against the suspension with the known All adjustments are made Subclaims denehiar. An embodiment of the invention is shown in the drawing shown. They show: FIG. 1 the diagram of a drum filter in a longitudinal center section and FIG. 2 in a side view.
Ein in Fig. 1 und 2 dargestelltes Trommelfilter weist einen Trog 1 für die Aufnahme der zu filternden Suspension 2 auf. In diesem Trog l taucht eine zylindrische Filtertrommel 3 ein, welche mittels eines nicht dargestellten Antriebs um die Achse (Welle 4) drehbar ist. Die Welle 4 ist nicht auf den Stirnwänden 5 des Troges 1 gelagert; die Lager 6 ruhen vielmehr auf außen an den Stirnwänden 5 befestigten Taschen 7, und zwar an deren stirnseitiger Außenwand 12. Die B»lden der ltelle 4 führen durch die Stirnwände 5 hindurch, und zwar durch eine Öffnung 8, die etwas größer als die Welle 4 an dieser Stelle ist, so daß hier eine Leckage (Pfeil p) vorhanden ist.A drum filter shown in FIGS. 1 and 2 has a trough 1 for taking up the suspension to be filtered 2. One dives into this trough cylindrical filter drum 3, which by means of a drive, not shown is rotatable about the axis (shaft 4). The wave 4 is not on that End walls 5 of the trough 1 mounted; the bearings 6 rather rest on the outside of the Pockets 7 attached to end walls 5, specifically on their end outer wall 12. The shutters of the point 4 lead through the end walls 5, specifically through one Opening 8, which is slightly larger than the shaft 4 at this point, so that here one Leakage (arrow p) is present.
Die Leckflüssigkeit fließt in die als Sammelbehalter ausgebildeten Taschen 7 und wird über Rohrstutzen 10 abgeleitet und auf nicht dargestellte Weise der Trog 1 wieder zugeführt. Die linke Tasche 7 (Fig. 1) weist ferner eine Überlaufkante 11 auf. Din auf der Welle 4 zwischen dem Lager 6 und der Öffnung 8 befestigter Abstreifring 13 verhindert, daß die teckflüssigkeit über die Welle 4 zum Lager 6 gelangt.The leakage fluid flows into the container designed as a collecting tank Bags 7 and is derived via pipe socket 10 and in a manner not shown the trough 1 is supplied again. The left pocket 7 (Fig. 1) also has an overflow edge 11 on. Din on the shaft 4 between the bearing 6 and the opening 8 fixed wiper ring 13 prevents the spill fluid from reaching the bearing 6 via the shaft 4.
