Description
Anschwemmfilter.
Die Erfindung bezieht sich auf Anschwemmfilter mit einem Spalte aufweisenden Tragkorper für die ansehwemmbare Filter- masse. Bei bekannten Anschwemmfiltern werden die feinen Spalte zum Beispiel von aufeinandergeschichteten Ringscheiben gebildet. zwisehen denen durci Unebenheiten der Ringflächen geringe Abstände verbleiben. ist ist das nach der Erfin- dung ausgebildete Anschwemmfilter dadurch gekennzeichnet.
da# der Tragkorper aus einer Vielzahl paralleler, gegeneinander anliegender S besteht. Bei einer bevorzugten Ansführungsform können diese parallelen, gegenein ander anliegenden Stäbe den Mantel eines rohrförmigen, zum Beispiel zylindrischen oder prismatischen Hohlkörpers bilden.
Ein solcher Tragkörper kann aus Draht abschnitten gleicher Länge verhältnismä#ig einfacli hergestellt werden. Die Durchlässig- keit des Filters kann auf einfache Weise da Inrch variiert werden, dass bei gegebener Grö#e der Mantelfläche einer Filterkerze Stähe von grö#erem oder geringerem Durchmesser verwendet, werden. Bei dickeren Stä ben ergibt sich entsprechend der gerinoeren Anzahl von Stäben eine geringere Anzahl von Spaten und umgekehrt.
Statt in einer Lage können die Stäbe aneth in zwei oder mehr dicht aneinander liegenden Schichten angeordnet sein. Sie stehen dabei zweckmä#ig in benachbarten Schichten auf Lücke. Dadurch kann zugleich die Steifigkeit : ler Wandung des Tragkorpers erhöht werden.
Zu dem gleiehen Zweek können im Innern des von den Stäben gebildeten Hohlkörpers Abstützungen vorgesehen sein, die ein Durch- biegen der Stäbe unter dem Druek der zu filtrierenden Flüssigkeit verhüten.
Die Erfindung wird im folgenden an Hand der Zeiehnung beispielsweise erläutert.
Fig. 1 ist die Seitenansicht eines nach der Erfindung ausgebildeten Filters in Kerzen- form.
Fig. 2 ist eine Draufsicht auf das Filter nach Fig. 1.
Fig. 3 ist ein Mittellängsschnitt nach Linie III-III in Fig. 1.
Fig. 4 ist ein Quersehnitt nach Linie TV-IV in Fig. 3.
Fig. 5 zeigt einen Querschnitt durch eine andere Ausfiihrungform des Filters in der Darstellungsweise der Fig. 4.
Das Filter weist ein Auslaufrohr 1 auf. dessen Wandung mit Öffnungen 11 versehen ist. Auf dieses Rohr sind an den Enden und in der Mitte des Filters Ringscheiben @ 2 auf- geschweisst, auf deren Umfang eine Vielzahl von parallelen, gegeneinander anliegenden Stäben 3 angeordnet ist, welche den Mantel der Filterkerze bilden. Diese Stäbe können je nach der Anwendung des Filters aus ver schiedenen geeigneten Werkstoffen, zum Beispiel aus Eisen, Kupfer, Messing oder nicht- rostenden Eisenlegierungen, bestehen. Auch gummierte Metallstäbe können Anwendung finden.
Durch die Stützwände 2 ist der Innenraum des Filters in mehrere Staubecken unterteilt.
Damit die Stäbe 3 sich bei der Rüekspülung nicht nach aussen durchbiegen können, sind an einer oder mehreren Stellen des Filterumfanges Ringe 4 vorgesehen, welche die Stäbe umschlie#en. Diese Ringe liegen zweekmässig den Stützscheiben 2 gegenüber.
An den beiden Enden des Filterkörpers werden die auf gleiche Länge geschnittenen Stable zusammen mit den endständigen Stütz- ringen die mit den Stabenden versehweisst oder verlötet sein können, unter Zwischen- schaltung von Dichtungsringen 5 gegen den Boden 6 nid den Deckel 7 des Filterkorpers gepresst. Die Zugstange 8 dient zur Verspannung. Der Deekel 7 wird durch die auf das Ende der Stange 8 aufschraubbare AIutter 9 tinter Zwisehenlage von Diehtungsscheiben 10 gegen das obere Ende der Filterkerze bzw. gegen den Diehtungsring 5 gepresst.
Dadureh wird auch das untere Kerzenende gegen den Boden 6, bzw. die auf dem Boden liegende Dichtungsscheibe 5 gepresst. Das untere Ende der Stange 8 ist in der Hülse 12 2 befestigt, die Durchflussöffnungen 13 aufweist und mittels der Mutter 16 am Auslaufstutzen 14 be festigt ist.
Bei der in Fig. 5 gezeigten Ausführungsform sind zwei konzentrische Lagen von Stäben vorgesehen, nämlich au#er den Stäben 3 eine weitere Schicht von Stäben 15, die zu den Stäben 3 auf Lüeke stehen.
Die naeh der Erfindung ausgebildeten Kerzen für Ansehwemmfilter können bis zu Längen von 1 m und mehr hergestellt werden, wenn eine genügende Anzahl von Stützringen vorgesehen wird.
Precoat filter.
The invention relates to precoat filters with a support body, which has a column, for the filter mass which can be exposed to water. In known precoat filters, the fine gaps are formed, for example, by stacked annular disks. between which small gaps remain due to the unevenness of the ring surfaces. the precoat filter designed according to the invention is characterized.
because # the support body consists of a large number of parallel, mutually adjacent S. In a preferred embodiment, these parallel rods resting against one another can form the jacket of a tubular, for example cylindrical or prismatic hollow body.
Such a support body can be produced relatively simply from wire sections of the same length. The permeability of the filter can be varied in a simple manner because, for a given size of the outer surface of a filter candle, a diameter of larger or smaller diameter is used. In the case of thicker rods, the number of spades is smaller, and vice versa, corresponding to the smaller number of rods.
Instead of being in one layer, the rods can be arranged in two or more layers lying close to one another. They are expediently placed on gaps in adjacent layers. As a result, the rigidity of the wall of the supporting body can be increased at the same time.
For the same purpose, supports can be provided inside the hollow body formed by the rods, which prevent the rods from bending under the pressure of the liquid to be filtered.
The invention is explained below with reference to the drawing, for example.
1 is a side view of a candle-shaped filter constructed according to the invention.
FIG. 2 is a top plan view of the filter of FIG. 1.
FIG. 3 is a central longitudinal section along line III-III in FIG. 1.
FIG. 4 is a cross section along line TV-IV in FIG. 3.
FIG. 5 shows a cross section through another embodiment of the filter in the representation of FIG. 4.
The filter has an outlet pipe 1. the wall of which is provided with openings 11. Annular disks @ 2 are welded onto this tube at the ends and in the middle of the filter, on the circumference of which a large number of parallel, mutually adjacent rods 3 are arranged, which form the jacket of the filter candle. Depending on the application of the filter, these rods can consist of various suitable materials, for example iron, copper, brass or non-rusting iron alloys. Rubberized metal rods can also be used.
The interior of the filter is divided into several reservoirs by the support walls 2.
So that the rods 3 cannot bend outward during backflushing, rings 4 are provided at one or more points on the filter circumference, which surround the rods. These rings are two-way opposite the support disks 2.
At the two ends of the filter body, the rods cut to the same length, together with the end support rings which can be welded or soldered to the rod ends, are pressed against the bottom 6 and the cover 7 of the filter body with the interposition of sealing rings 5. The pull rod 8 is used for bracing. The cover 7 is pressed by the nut 9, which can be screwed onto the end of the rod 8, against the upper end of the filter candle or against the lock ring 5, between the sandwich of the washers 10.
In this way, the lower end of the candle is also pressed against the floor 6 or the sealing washer 5 lying on the floor. The lower end of the rod 8 is fixed in the sleeve 12 2, which has flow openings 13 and is fastened by means of the nut 16 on the outlet nozzle 14 BE.
In the embodiment shown in FIG. 5, two concentric layers of bars are provided, namely in addition to the bars 3 another layer of bars 15 which are positioned on a gap with respect to the bars 3.
The candles designed in accordance with the invention for waterborne filters can be manufactured up to lengths of 1 m and more if a sufficient number of support rings is provided.
