Description

Bekannt sind Platten- und Taschenstaubfilter, die mit Filtergeweben beliebiger Art, z. B. Textilgewebe, Metallgewebe, gummierter Zellfaser od. dgl., derart bespannt sind, daß die Luft zwei gleiche oder verschieden geartete Gewebe hintereinander zu durchtreten hat. In der Regel ist die erstere Abscheidungsart gröber, die zweite feiner. Plate and pocket dust filters with filter fabrics are known of any kind, e.g. B. textile fabric, metal fabric, rubberized cell fiber or the like., are covered in such a way that the air is two identical or different types of tissue has to step through one after the other. Usually the former is the type of deposition coarser, the second finer.

Bislang mußten nun solche Filterrahmen in der Regel aus dem Apparat herausgezogen und umständlich gereinigt werden. Jedenfalls ist es nicht bekanntgeworden, daß, abgesehen von der ersteren, gröberen Filterwand, die zweite ohne besondere Umstände von ihrem abgeschüttelten Staub befreit werden konnte.Up to now, such filter frames usually had to be removed from the apparatus pulled out and laboriously cleaned. In any case, it has not become known that, apart from the first, coarser filter wall, the second without any particular one Circumstances could be freed from their shaken dust.

Diesen Ubelstand beseitigt die nachstehend beschriebene und in der Zeichnung in einem Ausführungsbeispiel dargestellte Erfindung. This problem is eliminated by the one described below and in the Drawing shown in an exemplary embodiment of the invention.

In Fig. I ist mit c die erste Filterwandung. mit b die zweite Filterwandung im Rahmen a bezeichnet. In Fig. I, c is the first filter wall. with b the second filter wall referred to in frame a.

Bei der Filterwandung c wird durch Schütteln oder Anschlagen des Rahmens an der Stelle g (Fig. 2) der Staub losgelöst, worauf er, wie Fig. I links zeigt, ohne Behinderung abfallen kann.When filter wall c is shaken or hit the frame at point g (Fig. 2) the dust is detached, whereupon it, as Fig. I shows on the left, can fall off without hindrance.

Gleichzeitig löst sich aber auch unter diesem Einfluß der Staub an der zweiten Filterfläche b, der praktisch abgesperrt wäre, wenn nicht für Abfluß Sorge getroffen würde. Dies geschieht, indem am unteren Ende des Filterrahmens ein elastischer Stoff d derart angeheftet wird, daß die Klappen c, f mit Hilfe ihrer Eigenspannung den Zwischenraum zwischen den beiden Filterwandungen während der Besaugung des Filters schließen und keine Falschluft samt Grobstaub eintreten lassen. Beim Abklopfvorgang fällt, wie in Fig. I links dargestellt, der Feinstaub losgelöst von der zweiten Filterwandung b im Raum k auf die erwähnte elastische Klappe e, die sich infolge des Eigengewichtes des Staubes so weit öffnet, daß letzterer herausrieseln kann. In der Regel kommt es höchstens zu einer Staubstauung von I bis 2 cm Höhe, deren Gewicht ausreicht, um beim Anschlagen des Filterrahmens jeweils wieder genügend Staub durchrieseln zu lassen. Da während des Abklopfvorganges grundsätzlich der Luftzug im Filter abgestellt ist, bleibt die Gefahr, daß während des Abklopfens durch den Luftzug der Feinststaub nicht austreten könnte, beseitigt. Wird der Luftzug dann wieder freigegeben, so werden die elastischen Klappen e, f wieder hochgesaugt, um so mehr, als ihnen dabei ihre Federung zu Hilfe kommt.At the same time, however, the dust also dissolves under this influence the second filter surface b, which would be practically closed off, if not for drainage Concern would be hit. This is done by placing one at the bottom of the filter frame elastic fabric d is attached in such a way that the flaps c, f with the help of their Internal stress in the space between the two filter walls during suction close the filter and do not allow any false air or coarse dust to enter. At the As shown on the left in FIG the second filter wall b in space k on the aforementioned elastic flap e, the opens so far as a result of the weight of the dust that the latter trickles out can. As a rule, there is at most a dust accumulation of 1 to 2 cm in height, whose weight is sufficient to be sufficient again when the filter frame is hit Let dust trickle through. Since during the knocking process, basically the If there is no draft in the filter, there is still a risk of being knocked off the fine dust could not escape due to the draft, eliminated. Will the draft then released again, the elastic flaps e, f are sucked up again, all the more so because their suspension comes to their aid.

PATENTANSPRUCH: Staubfilterrahmen, bestehend aus zwei in Strömungsrichtung der Staubluft mit Abstand hintereinander angeordneten, lotrechten Filterflächen verschiedener Maschenweite, die von Zeit zu Zeit durch Abklopfen vom Staub gereinigt werden, dadurch gekennzeichnet, daß die Staubaustragöffnung am unteren Ende des doppelt bespannten Filterrahmens durch eine beim Abklopfen sich unter der Belastung des abgeschiedenen Staubes selbsttätig öffnende und dann, unterstützt durch den Saugzug, wieder schließende Klappe abgeschlossen wird. PATENT CLAIM: Dust filter frame, consisting of two in the direction of flow the dusty air spaced one behind the other, vertical filter surfaces various mesh sizes, which are cleaned from dust from time to time by knocking them off are, characterized in that the dust discharge opening at the lower end of the double-covered filter frame by one when knocking down under the load of the separated dust automatically opening and then, supported by the Induced draft, closing flap is completed.
