PATENTANSPRÜCHE
1. Kesseldruckfilter, bestehend aus einer Anzahl mit Füllmaterial gefüllter schlauchförmiger Filterelemente, dadurch gekennzeichnet, dass die Filterelemente (9) auf einem herausnehmbaren Hohlkörper (7) hintereinander angeordnet sind.
2. Vorrichtung nach Patentanspruch 1, dadurch gekennzeichnet, dass der Hohlkörper (7) auf einer Ringplatte (29) frei gelagert und mit seiner Gegenseite durch einen Flansch (26) oder eine Kupplung an einem Verbindungsrohr (8) befestigt ist.
3. Vorrichtung nach Patentansprüchen 1 und 2, dadurch gekennzeichnet, dass Hohlkörper (7) mit verschiedener Länge und Schlauchzahl parallel nebeneinander angeordnet sind.
4. Vorrichtung nach Patentansprüchen 1 bis 3, dadurch gekennzeichnet, dass eine Sammelleitung (6) zur Filtratableitung innerhalb oder ausserhalb des Kessels angebracht ist.
5. Vorrichtung nach Patentansprüchen 1 bis 4, dadurch gekennzeichnet, dass unterhalb der Filterelemente ein Strömungsverteiler (22) angebracht ist.
Die Erfindung betrifft ein Kesseldruckfilter, das aus einer Anzahl schlauchförmiger Filterelemente besteht.
Nach dem schweizerischen Patent Nr. 604 823 ist ein Filterelement für Kesseldruckfilter bekannt, das aus einem schlauchförmigen Filtermittel besteht, welches an seiner unteren Seite verschlossen und an seiner befestigten Oberseite offen ist und dessen Innenraum mit losem Füllmaterial beschickt ist.
Die Einzelelemente sind dabei auf einer Tragplatte oder Tragscheibe befestigt. Das ganze Filterpaket kann so nach dem Öffnen des Deckels aus dem Filterkessel zur Kontrolle oder Reinigung mit Hilfe einer Hebevorrichtung nach oben ausgezogen werden. Dabei sind beispielsweise die Einzelelemente, die sich im Innern des Elementpaketes befinden, schwer demontierbar und meist ohne Entfernung der umgebenden Filterschläuche überhaupt nicht zu entfernen und zu ersetzen.
Bei Defekt eines einzigen Schlauchelementes ist daher die Demontage einer ganzen Reihe Einzelelemente erforderlich.
Zum Herausheben des gesamten Schlauchfilterpaketes sind auch wegen des Gewichtes der Trägerplatte und der Gesamtzahl der Elemente grosse Kranaufbauten oberhalb des Filterkessels erforderlich, so dass beispielsweise von vornherein auch eine grössere Bauhöhe vorgesehen werden muss.
Aufgabe der Erfindung ist es, ein Filterelement zu schaffen, das die genannten Nachteile beim Ausbau zwecks Reinigung und Kontrolle vermeidet.
Diese Aufgabe wird erfindungsgemäss nach Patentanspruch 1 gelöst und ist dadurch gekennzeichnet, dass die Filterelemente auf einem herausnehmbaren Hohlkörper hintereinander angeordnet sind.
Die Erfindung soll durch eine Zeichnung näher beschrieben werden. Es zeigen:
Fig. 1 im Aufriss ein erfindungsgemässes Filterelement in einem Filterkessel,
Fig. 2 einen Schnitt A-A durch die Vorrichtung der Fig. 1,
Fig. 3 die verkürzte Darstellung des Filterelementes.
Der die Filterelemente aufnehmende Kessel 1 ist im unteren Teil mit einem Eingang 2 für das zu filtrierende Medium und einem Ausgang 13 für die Filterrückstände versehen. Im Deckel 5 des Kessels 1 befindet sich die Entlüftung 4. Die aus mehreren Filterelementen zusammengesetzte Einheit besteht aus den Filterschläuchen 9, 9' usw. Diese sind in einem Hohlkörper 7, der als Sammelrohr dient, befestigt. Filterkessel 1 und Deckel 5 sind über einen T-förmigen Zwischenring 25 verbunden. Dieser Zwischenring 25 wird am Flansch 14 des Kessels 1 mit dem Flansch 23 der Unterseite des Zwischenstücks 25 in bekannter Weise lösbar befestigt.
Der eine Halbkreis des Zwischenringes 25 weist auf seiner Innenwand einen aufgeschweissten Auflagering 29 auf.'In der Wand des anderen Halbkreises des Zwischenstückes 25 sind Bohrungen angebracht, durch welche die Verbindungsrohre 8 nach aussen führen und in ein Sammelrohr 6 mit einem Austritt 3 münden.
Der Deckel 5 ist mit seinem Flansch 15 am oberen Flansch 24 des Zwischenstückes 25 befestigt.
Die Entfernung einer zusammengesetzten Einheit 7 erfolgt auf einfachste Weise durch Lösen der Befestigungen an den Flanschen 15 und 24. Dadurch lasst sich der Deckel 5 abheben. Die Herausnahme der Filterelement-Einheit erfolgt nun lediglich durch Lösen der Flansche 26 am jeweiligen Hohlkörper 7 und des Flansches 27 vom Verbindungsrohr 8 und Herausziehen der Filterelemente, welche kontrolliert werden sollen oder deren Filterschläuche ausgewechselt werden müssen.
Anstelle der Flansche 26, 27 können auch Kupplungen als Verbindung dienen.
Zur Kontrolle jedes Filterelementes können Schaugläser und Probehähne in die Verbindungsrohre 8 ausserhalb der Kesselwand angebracht werden.
Die Sammelleitung .6.kWn 4euch innerhalb des Filterkessels liegen. In diesem Fall geht die Sammelleitung 6 durch eine einzige Bohrung durch das Zwischenstück 25.
Die unterhalb der Filterelemente angebrachte Verteilerplatte 22 soll eine# turbulente Strömung im Filterkessel verhindern, um den auf die Filterschläuche aufgebauten Filterkuchen nicht abzuschwemmen.

PATENT CLAIMS
1. Boiler pressure filter, consisting of a number of tubular filter elements filled with filler material, characterized in that the filter elements (9) are arranged one behind the other on a removable hollow body (7).
2. Device according to claim 1, characterized in that the hollow body (7) is freely supported on an annular plate (29) and is attached with its opposite side by a flange (26) or a coupling to a connecting pipe (8).
3. Device according to claims 1 and 2, characterized in that hollow bodies (7) with different lengths and numbers of tubes are arranged parallel to one another.
4. Apparatus according to claims 1 to 3, characterized in that a collecting line (6) for filtrate drainage is attached inside or outside the boiler.
5. Device according to claims 1 to 4, characterized in that a flow distributor (22) is attached below the filter elements.
The invention relates to a boiler pressure filter which consists of a number of tubular filter elements.
According to Swiss Patent No. 604 823, a filter element for boiler pressure filters is known, which consists of a tubular filter medium which is closed on its lower side and open on its fixed upper side and the interior of which is filled with loose filler material.
The individual elements are attached to a support plate or support disk. After opening the cover, the entire filter package can be pulled out of the filter tank for inspection or cleaning with the help of a lifting device. For example, the individual elements located inside the element package are difficult to dismantle and usually cannot be removed or replaced at all without removing the surrounding filter hoses.
If a single hose element is defective, a whole series of individual elements must be dismantled.
In order to lift out the entire bag filter package, because of the weight of the carrier plate and the total number of elements, large crane structures are required above the filter vessel, so that, for example, a greater overall height must be provided from the start.
The object of the invention is to create a filter element which avoids the disadvantages mentioned when dismantling for the purpose of cleaning and checking.
This object is achieved according to the invention according to patent claim 1 and is characterized in that the filter elements are arranged one behind the other on a removable hollow body.
The invention is to be described in more detail by means of a drawing. Show it:
1 shows an elevation of a filter element according to the invention in a filter vessel,
Fig. 2 shows a section A-A through the device of Fig. 1,
3 shows the abbreviated representation of the filter element.
The tank 1 accommodating the filter elements is provided in the lower part with an inlet 2 for the medium to be filtered and an outlet 13 for the filter residues. The vent 4 is located in the cover 5 of the boiler 1. The unit, which is composed of several filter elements, consists of the filter hoses 9, 9 'etc. These are fastened in a hollow body 7, which serves as a collecting pipe. The filter vessel 1 and cover 5 are connected via a T-shaped intermediate ring 25. This intermediate ring 25 is releasably attached to the flange 14 of the boiler 1 with the flange 23 of the underside of the intermediate piece 25 in a known manner.
One semicircle of the intermediate ring 25 has a welded-on support ring 29 on its inner wall. In the wall of the other semicircle of the intermediate piece 25, bores are made through which the connecting pipes 8 lead to the outside and open into a collecting pipe 6 with an outlet 3.
The cover 5 is fastened with its flange 15 on the upper flange 24 of the intermediate piece 25.
An assembled unit 7 can be removed in the simplest manner by loosening the fastenings on the flanges 15 and 24. The cover 5 can thereby be lifted off. The removal of the filter element unit now takes place only by loosening the flanges 26 on the respective hollow body 7 and the flange 27 from the connecting pipe 8 and pulling out the filter elements which are to be checked or whose filter hoses have to be replaced.
Instead of the flanges 26, 27, couplings can also serve as connections.
To check each filter element, sight glasses and test taps can be attached to the connecting pipes 8 outside the boiler wall.
The collecting line .6.kWn 4e also lie within the filter vessel. In this case, the collecting line 6 runs through a single bore through the intermediate piece 25.
The distribution plate 22 attached below the filter elements is intended to prevent a turbulent flow in the filter vessel in order not to wash away the filter cake built up on the filter hoses.
