Problemproblem

LösungSolution

Taschen!uftfilter üblicher Baüari weisen in Ihren Einzelbeuteln Abstandhalter auf, welche die freie Durchströmung des zu filternden Luftstromes unterstutzen sollen. Pocket air filters from conventional manufacturers have spacers in their individual bags, which are intended to support the free flow of the air stream to be filtered.

In ihrer einfachsten Form bestehen diese Abstandhalter aus Einzelstegen oder längs zur Strömungsrichtung liegende Abstandhalter-Nähten, schmalen Schweiß- oder Klebeverbindungen oder keilförmigen Verbindungselementen.In their simplest form, these spacers consist of individual webs or spacer seams running along the flow direction, narrow welded or adhesive joints or wedge-shaped connecting elements.

Alle genannten Maßnahmen verhindern aber nicht, daß die Filterfläche im Lufteintrittsbereich nur unvollkommen genutzt wird.However, all of the measures mentioned do not prevent the filter surface in the air inlet area from being used only incompletely.

Es ist eine bekannter Nachteil der Taschenfi1terkonstruktion, daß die Einström-Filterflachen des Taschenfilters, insbesondere bei hoher spezifischer Einzelbeutelzanlf im Lufteintrittsbereich kaum durch strömt werden und dadurch auch keinen Staub einspeichern . Die Außenflächen der nebeneiander liegenden Einzelbeutel werden konstruktionsbedingt nahe der Kopfplatte durch den Luftstrom gegeneinander gedrückt und können nicht durchströmt werden.Die Folge davon sind ein Verlust an aktiver Filterfläche, hoher Durchflußwiderstand und geringere Staub-Speicherfähigkeit des Filters.Beide Parameter sind Kennwerte für die optimale Leistung eines Taschen-Luftfilters.It is a known disadvantage of the pocket filter design that the inflow filter surfaces of the pocket filter, particularly with a high specific number of individual bags in the air inlet area , are hardly flown through and therefore do not store any dust. Due to the design, the outer surfaces of the individual bags lying next to each other are pressed against each other by the air flow near the head plate and cannot be flowed through. The result of this is a loss of active filter surface, high flow resistance and lower dust storage capacity of the filter. Both parameters are characteristics for the optimal performance of a pocket air filter.

Der in den Schutzansprüchen 1-3 angegebenen Erfindung liegt das Problem zugrunde ein Taschenfilter herzustellen, dessen Filtermedium nahezu vollständig durchströmt werden kann, wozu eine gegenseitige Behinderung der Einzeltaschen vermieden werden muß.The invention specified in claims 1-3 is based on the problem of producing a pocket filter whose filter medium can be almost completely flowed through, for which purpose mutual obstruction of the individual pockets must be avoided.

Das Problem wird mit den in Schutzansprüchen 1-3 aufgeführten Merkmalen wie folgt gelöst:Bildung eines strömungsgUnstigen, kaum Widerstand erzeugenden, Luft durchlässigen Gitterkörpers, der reinluftseitig zwischen den Einzeltaschen, unmittelbar hinter dem Lufteintritt angeordnet ist.The problem is solved with the features listed in claims 1-3 as follows: Formation of a streamlined, barely drag-generating, air-permeable grid body that is arranged on the clean air side between the individual pockets, immediately behind the air inlet.

Claims (3)

SchutzansprücheProtection claims 1.

Pocket air filter (1) characterized in that as an air outflow aid there are grid bodies (2) between the individual pockets (3) at their air inlet, whereby mutual contact and obstruction of the individual pockets at the air outlet is avoided. 2. Taschenluftfilter nach Anspruch(l) dadurch gekennzeichnet, daß an einer senkrechten Einze1beute1-Verbindung(4) ein gitterförmiges Band befestigt ist, daß durch Umbiegen einen tropfenförmigen Gitterkörper(2) bildet und dessen längsseitige ^ offenen Kanten in die Einzelbeutel-Verbindung(4) intergriert werden.2. Pocket air filter according to claim (1), characterized in that a grid-shaped band is attached to a vertical single-bag connection (4), which forms a drop-shaped grid body (2) by bending and whose longitudinal open edges are integrated into the single-bag connection (4). 3. Taschenluftfilter nach Anspruch(l) dadurch gekennzeichnet, daß der Abstand erzeugende Gitterkörper (2) in anderer Form, z.B.: als Gitterrohr eingelegt wird oder in Teilelementen zu ähnlicher Form zusammengesetzt wird.3. Pocket air filter according to claim (1), characterized in that the grid body (2) creating the distance is inserted in another form, e.g. as a grid tube or is assembled in sub-elements to form a similar form.
