Abstract

Folded filter element for mining and tunnelling or other applications with restricted space does not require the laborious embedding or vulcanising of conventional elements in the radial star shape. The connections can be easily applied at the flanges by sewing or bending if the folds are made in the fashion of Chinese lanterns of polygonal section. The depths of the plaits can be chosen to suit the partic application, also the number of corners (four, six, eight, etc.). The end of faces are plane or on edge, but without plaits.

Description

@eschreibung und Erläuterung zur ZusatzanmeldungDescription and explanation of the additional registration

"Verfahren und Vorrichtung zur Herstellung von radial-profilierten Filterkörpern zum Reinigen von vorzugsweise staubhaltiger Luft" Zusatzanmeldung zu P 27 22 272.6 In der @a@@ tanmeldung wird ein Filter beschrieben, der vorzugsweise für den Rergbau und Tunnelbau für sehr beengte Platzverhältnisse hergestellt sein soll."Method and device for the production of radially-profiled Filter bodies for cleaning air that is preferably dusty "additional application Re P 27 22 272.6 The @ a @@ tanmeldung describes a filter that preferably for mining and tunneling in very confined spaces target.

Dieser filter soll aber auch gleichzeitig in der Lage sein evtl. @eißgase, die mit Staub und oder anderen Schadgasen belastet sind, zu reinigen.However, this filter should also be able at the same time to which are contaminated with dust and / or other harmful gases to be cleaned.

Aus diesem Grunde wurde erfindungsgemäß vorgeschlagen, die Filter nicht in bekannter Sternfilterbauweise herzustellen, wobei die Sternfilterbauweise an den Gaszuführungsstücken und deckelförmigen Abschlußstücken nur durch Eingießen und/oder aufwendigem Vulkaiii si eren aufgesetzter Flanschen entsprechend gebrauchsfähig gemacht werden kann, sondern der erfindungsgemäße ilter weist radialangeordnete Profilierungen auf, so daß der erforderliche flanschförmige Anschluß oder der deckelförmige Abschluß in einfachsterweise aus dem gleichen Material anekantet, angenäht, oder mit temperaturfestem Material verbunden werden kann.For this reason it was proposed according to the invention, the filter not to produce in the known star filter design, the star filter design on the gas supply pieces and cover-shaped end pieces only by casting and / or expensive Vulkaiii si eren attached flanges usable accordingly can be made, but the filter according to the invention has radially arranged Profiles on, so that the required flange-shaped connection or the lid-shaped Finishing in the simplest way made of the same material anked, sewn, or can be connected with temperature-resistant material.

Die Zusatzerfindung befaßt sich mit dem Verfahren zur Herstellung von radial-profilierten Filterkörpern, die erfindungsgemäß nach einem Treppen-Falt-Verfahren geformt werden.The additional invention deals with the method of manufacture of radially profiled filter bodies, which according to the invention according to a stair-folding method be shaped.

Bei dem erfindungsgemäßen Verfahren lassen sich die Falttiefe sowie die Form, z.B, viereckig, sechseckig, achteckig usw., individuell für den Einsatzfall bestimmen.In the method according to the invention, the depth of fold as well as the shape, e.g. square, hexagonal, octagonal, etc., individually for the application determine.

Das Treppen-Falt-Verfahren beinhaltet eine Aneinanderlegung von Eniff-Falten.The stair-folding process involves juxtaposing Eniff folds.

Diese erfindungsgemäßen Kniffalten werden nach Formwunsch unter einer zu bestimmenden Gradzahl radial gefalten, so daß ein Körper mit einer seitlichen Stoßstelle, die als Nahtstelle ausgebildet sein kann, entsteht. Die Enden der durch das Treppen-Falt-Verfahren geformten Filterkörper sind flanschartig gefalten.According to the desired shape, these creases according to the invention are under one to be determined number of degrees folded radially so that a body with a lateral Joint, which can be designed as a seam, arises. The ends of the through The filter bodies formed using the stair-folding process are folded in a flange-like manner.

In der beiliegenden Zeichnung Ä und B sind erfindungsgemäß gefaltete Staub-Filterkörper dargestellt.In the accompanying drawings A and B are folded according to the invention Dust filter body shown.

In der Äbb. A und B verschiedene Formen von Vieleckprofilierungen mit 1) der gefaltete Flanschansatz zum Anschluß an einen Reingaskanal mit 2) Kniff-Falten mit 3) die angefalteten Flanschen z.B. für die Bodenplatte, die zweckdienlicherweise aus gleichem filternden Material bestehen und dadurch die Filterfläche noch erhöhen.In Fig. A and B different forms of polygonal profiles with 1) the folded flange attachment for connection to a clean gas duct with 2) pinched folds with 3) the folded flanges e.g. for the base plate, which expediently consist of the same filtering material and thereby increase the filter surface even more.

mit 4) z.B. die aneinanderstoßenden oder überlappenden Faltprofile, die dort genäht, geklebt, genietet, geschraubt oder mit einer anderen Verbindungsart miteinander verbunden werden können.with 4) e.g. the abutting or overlapping folding profiles, which are sewn, glued, riveted, screwed or with another type of connection can be connected to each other.

Die Abb. C - d zeigt mit 1) einen gefalteten Flanschansatz mit 3) ebenfalls einen gefalteten Flanschansatz zur Aufnahme eines Verschlußdeckels mit 5) Filterspannrahmen, der z.B. aus Rundprofilen bestehen kann über die die Filtertasche gezogen wird mit 6) die Eniff-Falten-eite mit 7) eine glatte Fläche, die an den Ecken 8 mit den Kniff-Falten-Profilierungen verbunden ist.Fig. C - d shows with 1) a folded flange with 3) also has a folded flange attachment to accommodate a closure cover 5) Filter clamping frame, which can consist of round profiles, for example, over which the filter pocket is drawn with 6) the Eniff fold side with 7) a smooth surface that is attached to the Corners 8 is connected to the pinch-fold profiles.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebene und dargestellte Ausbildungsform beschränkt, sondern es sind z&hlreiche Abänderungen möglich, ohne j jedoch von den Grundgedanken abzuweichen, ein Verfahren zur erstellung von radial-profilierten Filtern zu wählen, wobei diese Filter nach einem Treppen-Falt-Verfahren in einfachsterweise ohne großtechnischen Maschinenaufwand geformt untereinander gestoßen und verbunden werden können, wobei die Endstücke als Flanschanschlußstücke aus gleichem Material angefaltet sind.Of course, the invention is not limited to the above in detail The form of training described and illustrated is limited, but there are numerous Changes possible without however deviating from the basic idea, a procedure to choose for the creation of radially profiled filters, these filters according to a stair-folding process in the simplest possible way without large-scale machinery shaped can be butted and connected with each other, with the end pieces are folded as flange fittings made of the same material.
