Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Absaugen und Filtern staub- und/oder faserflugbelasteter Luft an Spinnereimaschinen sowie zum Reinigen des Filters von Ablagerungen durch Umkehrbeaufschlagung der betriebsmäßigen Luftströmungsrichtung, mit einem verschließbaren Ansaugkanal, einem Filter, einem Zuluftkanal, einem luftfördernden Ventilator und einem Abluftkanal.The invention relates to a device for extracting and filtering dust and / or fiber-polluted air on spinning machines and for cleaning the filter of deposits by reversing the direction of the air flow during operation, with a closable suction duct, a filter, an inlet air duct, an air-conveying fan and an exhaust air duct .

Als Stand der Technik ist bereits ein Filterkasten bekannt, welcher im wesentlichen aus einer druckseitigen Reinluftkammer und einer saugseitigen Rohluftkammer besteht (DE-OS 30 17 838). Die Rohluftkammer ist mit einem von einer Spinnereimaschine kommenden Saugkanal verbunden: in der Reinluftkammer befindet sich ein Ventilator; zwischen der Reinluftkammer und der Rohluftkammer ist ein Filter angeordnet. Von der Rohluftkammer geht ein absperrbarer, zu einer ständig betriebenen Zentralabsaugung führender Absaugkanal aus, wobei die Rohluftkammer kurzzeitig an die Zentralabsaugung anschließbar ist und der Auslaß der Reinluftkammer abgesperrt werden kann.A filter box is already known as prior art, which essentially consists of a pressure-side clean air chamber and a suction-side raw air chamber (DE-OS 30 17 838). The raw air chamber is connected to a suction duct coming from a spinning machine: there is a fan in the clean air chamber; A filter is arranged between the clean air chamber and the raw air chamber. From the untreated air chamber there is a lockable suction channel leading to a continuously operated central suction, the unfiltered air chamber being connectable to the central suction for a short time and the outlet of the clean air chamber being shut off.

Aufgabe der vorliegenden Erfindung ist es, ausgehend von dem eingangs genannten Stand der Technik die Vorrichtung so auszubilden, daß auf einfache Weise eine Vereinfachung der Reinigungsmöglichkeit des Filters gegeben ist.The object of the present invention is, based on the prior art mentioned at the outset, to design the device in such a way that the cleaning possibility of the filter is simplified in a simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Zuluftkanal und der Abluftkanal mindestens eine gemeinsame Wand aufweisen und daß die gemeinsame Wand in zwei Stellungen überführbar ist, wobei in der ersten Stellung der Zuluftkanal und der Abluftkanal geöffnet sind und in der zweiten Stellung bei verschlossenem Ansaugkanal eine Umkehr der Luftströmungsrichtung durch Schließen des Zuluft- und Abluftkanals sowie durch Schaffung zweier getrennter Luftdurchtrittsöffnungen zwischen dem Zuluftkanal und dem Abluftkanal erfolgt.This object is achieved in that the supply air duct and the exhaust air duct have at least one common wall and that the common wall can be moved into two positions, the supply air duct and the exhaust air duct being open in the first position and one in the second position when the intake duct is closed Reversal of the air flow direction by closing the supply air and exhaust air duct and by creating two separate air passage openings between the supply air duct and the exhaust air duct.

Hierdurch ergibt sich der Vorteil einer einfachen Bauform, wobei allein durch Umstellung der gemeinsamen Wand sowie durch Umkehr der Luftströmungsrichtung bei verschlossenem Ansaugkanal der Luftstrom zur Filterreinigung verwendet wird. Die gemeinsame Wand kann entweder als schwenkbare Klappe oder als Schieber ausgebildet sein, welcher zwei im rechten Winkel zueinander bestehende Bereiche aufweist, wobei der einzelne Bereich eine der beiden Stellungen der gemeinsamen Wand definiert.This results in the advantage of a simple design, the air flow being used for filter cleaning solely by changing the common wall and by reversing the air flow direction when the intake duct is closed. The common wall can either be designed as a pivotable flap or as a slide, which has two areas at right angles to one another, the single area defining one of the two positions of the common wall.

Durch kurzes Schwenken der Klappe bzw. Bewegen des Schiebers in die Entleerstellung wird damit der Luftstrom zur Filterreinigung verwendet, wobei die Umgebungsluft vom Gebläse angesaugt wird. Die Abluft wird hierbei so umgelenkt, daß sie im Filterraum einen Überdruck erzeugt. Dieser löst den Filterinhalt und bläst ihn, entgegen der normalen Luftrichtung, aus dem Filter in einen Abfallsammelbehälter.By briefly swiveling the flap or moving the slide into the emptying position, the air flow is used for filter cleaning, the ambient air being sucked in by the fan. The exhaust air is redirected so that it creates an overpressure in the filter chamber. This loosens the filter content and, contrary to the normal direction of air, blows it out of the filter into a waste collection container.

Weitere Vorteile der erfindungsgemäßen Konstruktion sind die Wartungsfreiheit, da kein mechanischer Abstreifer vorliegt, eine vollständige Entleerung des Filters in sehr kurzer Zeit, beispielsweise während des Kannenwechsels einer Spinnereimaschine, kompakte Raumverhältnisse sowie eine sehr gute Zugänglichkeit des Abfallsammelbehälters, wobei ein Auswechseln dieses Behälters während des Betriebes möglich ist.Further advantages of the construction according to the invention are the freedom from maintenance, since there is no mechanical scraper, complete emptying of the filter in a very short time, for example during the can change of a spinning machine, compact space conditions and very good accessibility of the waste collection container, whereby a It is possible to replace this container during operation.

In Fig. 1 und 2 ist schematisch eine Ausführungsform einer Vorrichtung zum Absaugen und Filtern staub- und/oder faserflugbelasteter Luft an einer Spinnereimaschine dargestellt. Hierbei ist der entsprechende Bereich der Spinnereimaschine mit einem Ansaugkanal 1 verbunden, welcher über einen Zuluftkanal 3 zu einem luftfördernden Ventilator 4 sowie zu einem Abluftkanal 5 führt. In dem Bereich zwischen dem Ansaugkanal 1 und dem Zuluftkanal 3 ist ein Filter 2 angeordnet.1 and 2 schematically show an embodiment of a device for extracting and filtering air contaminated with dust and / or fiber flights on a spinning machine. Here, the corresponding area of the spinning machine is connected to an intake duct 1, which leads via an inlet air duct 3 to an air-conveying fan 4 and to an exhaust air duct 5. A filter 2 is arranged in the area between the intake duct 1 and the supply air duct 3.

Wie ersichtlich, verlaufen der Zuluftkanal 3 und der Abluftkanal 5 über einen bestimmten Bereich parallel nebeneinander. In diesem Bereich weisen also der Zuluftkanal 3 und der Abluftkanal 5 eine gemeinsame Wand 7 auf. Diese gemeinsame Wand 7 ist mindestens teilweise als schwenkbare Klappe 9 ausgebildet, deren Schwenkachse 8 quer zur Luftströmungsrichtung des geöffneten Zu- und Abluftkanals angeordnet ist. Die Klappe 9 ist von Hand oder durch ein nicht näher dargestelltes elektrisches oder pneumatisches oder hydraulisches Arbeitselement betätigbar.As can be seen, the supply air duct 3 and the exhaust air duct 5 run parallel to one another over a specific area. In this area, the supply air duct 3 and the exhaust air duct 5 have a common wall 7. This common wall 7 is at least partially designed as a pivotable flap 9, the pivot axis 8 of which is arranged transversely to the air flow direction of the open supply and exhaust air duct. The flap 9 can be actuated by hand or by an electrical or pneumatic or hydraulic working element (not shown in more detail).

Unterhalb des Ansaugkanals 1 befindet sich ein Abfallsammelbehälter 6, welcher nach Fig. 1 durch eine schwenkbare Klappe 20 verschlossen ist. Die Klappe 20 ist mechanisch mit der Klappe 9 verbunden oder durch ein gleichzeitig mit der Beaufschlagung des Arbeitselementes der Klappe 9 beaufschlagtes Arbeitselement betätigbar.Below the intake duct 1 there is a waste collection container 6, which is closed by a pivotable flap 20 according to FIG. 1. The flap 20 is mechanically connected to the flap 9 or can be actuated by a working element which is simultaneously acted upon by the working element of the flap 9.

In Arbeitsstellung strömt die Luft in Pfeilrichtung von dem Ansaugkanal 1 durch den Filter 2 und den Zuluftkanal 3 sowie über den Ventilator 4 in den Abluftkanal 5. Soll eine Reinigung des Filters 2 vorgenommen werden, so wird nach Fig. 2 die Klappe 9 um ihre Drehachse 8 geschwenkt; auch die Klappe 20 wird so geschwenkt, daß ein Verschluß des Ansaugkanals 1 stattfindet, und zwar bei geöffnetem Abfallsammelbehälter.In the working position, the air flows in the direction of the arrow from the intake duct 1 through the filter 2 and the supply air duct 3 and via the fan 4 into the exhaust air duct 5. If the filter 2 is to be cleaned, the flap 9 according to FIG. 2 becomes about its axis of rotation 8 pivoted; also the flap 20 is pivoted so that a closure of the intake duct 1 takes place, with the waste container open.

Nunmehr wird die Umgebungsluft vom Ventilator 4 angesaugt und so umgelenkt, daß sie durch den Filter 2 hindurchtritt. Dadurch wird der Filterinhalt gelöst und entgegen der normalen Laufrichtung aus dem Filter in den Abfallsammelbehälter 6 geblasen. Allein durch diese kurzzeitige Umstellung der schwenkbaren Klappe 9 sowie durch Verschluß des Ansaugkanals 1 ist damit auf einfache und schnelle Weise eine wirksame Filterreinigung möglich.Now the ambient air is sucked in by the fan 4 and deflected so that it passes through the filter 2. As a result, the filter content is released and blown out of the filter into the waste collection container 6 against the normal direction of rotation. Effective filter cleaning is thus possible in a simple and quick manner solely by this brief changeover of the pivotable flap 9 and by closing the intake duct 1.

Bei der Ausführungsform nach Fig. 3 und 4 liegen wiederum der Zuluftkanal 3 und der Abluftkanal 5 im Bereich der gemeinsamen Wand 7 parallel nebeneinander. Statt der in Fig. 1 und 2 eingesetzten Klappe 9 findet jedoch bei der Ausführungsform nach Fig. 3 und 4 ein Schieber 10 Anwendung, welcher zwei im rechten Winkel zueinander stehende Bereiche 11 und 12 aufweist. Fig. 3 definiert hierbei die Arbeitsstellung - in diesem Fall dient der Bereich 12 zur Trennung des Zuluftkanals 3 von dem Abluftkanal 5, so daß die Luft, wie in Pfeilrichtung dargestellt, strömen kann. Dabei bleiben die Luftströme in den beiden Kanälen 3 bzw. 5.In the embodiment according to FIGS. 3 and 4, the supply air duct 3 and the exhaust air duct 5 in turn lie in parallel in the region of the common wall 7. Instead of the flap 9 used in FIGS. 1 and 2, in the embodiment according to FIGS. 3 and 4, however, a slide 10 is used which has two regions 11 and 12 which are at right angles to one another. 3 defines the working position - in this case the area 12 serves to separate the supply air duct 3 from the exhaust air duct 5, so that the air can flow as shown in the direction of the arrow. The air flows remain in the two channels 3 and 5.

In der in Fig. 4 dargestellten Filterreinigungsstellung ist der Schieber 10 so zwischen den Zuluftkanal 3 und den Abluftkanal 5 eingeschoben, daß der senkrechte Bereich 11 zur Wirkung kommt; dieser senkrechte Bereich 11 bildet eine Trennwand und verbindet die beiden Kanäle in zwei voneinander gesonderten Bereichen. Die Luftströmung wird von dem oberen in den unteren und vom unteren in den oberen Kanal umgeleitet. Damit läßt sich analog der Ausführungsform nach Fig. 1 und 2 wiederum der nicht näher dargestellte Filter von außen beaufschlagen, es tritt ein Lösen des Filterinhaltes und dessen Einblasen in den Abfallsammelbehälter statt.In the filter cleaning position shown in FIG. 4, the slide 10 is inserted between the supply air duct 3 and the exhaust air duct 5 in such a way that the vertical region 11 comes into effect; this vertical area 11 forms a partition and connects the two channels in two separate areas. The air flow is diverted from the upper to the lower and from the lower to the upper duct. Analogous to the embodiment according to FIGS. 1 and 2, the filter, which is not shown in detail, can thus be acted upon from the outside, and the filter contents are loosened and blown into the waste collection container.

Bei der Ausführungsform nach Fig. 5 und 6 kreuzen sich der Zuluftkanal 3′ und der Abluftkanal 5′ im Bereich der gemeinsamen Wand 7′. Wie ersichtlich, sind der Zuluftkanal 3′ und der Abluftkanal 5′ im Querschnitt jeweils halbrund ausgebildet. Die gemeinsame Wand 7′ wird von einer schwenkbaren Klappe 9′ gebildet, deren Schwenkachse 8′ diagonal zur Kreuzungsebene des Zuluftkanals 3′ und des Abluftkanals 5′ verläuft. Nach Fig. 5 strömt die Luft wiederum von dem Ansaugkanal über einen nicht näher dargestellten Filter in den Zuluftkanal 3′ sowie über den Ventilator 4 in den Abluftkanal 5′.In the embodiment according to FIGS. 5 and 6, the supply air duct 3 'and the exhaust air duct 5' cross in the region of the common wall 7 '. As can be seen, the supply air duct 3 'and the exhaust duct 5 'is semicircular in cross section. The common wall 7 'is formed by a pivotable flap 9', the pivot axis 8 'diagonally to the crossing plane of the supply air duct 3' and the exhaust duct 5 '. 5, the air in turn flows from the intake duct through a filter, not shown, into the supply air duct 3 'and via the fan 4 into the exhaust duct 5'.

Zur Reinigung des Filters wird nach Fig. 6 die schwenkbare Klappe 9′ um ihre Schwenkachse 8′ in die senkrechte Lage geschwenkt. Damit ergibt sich eine Verbindung der beiden Kanäle 3′ und 5′, wobei nunmehr die Luft, wie in Pfeilrichtung dargestellt, von dem linken Bereich des Abluftkanals 5′ in den unteren rechten Bereich des Zuluftkanals 3′, von dort über den Ventilator 4 in den rechten Bereich des Abluftkanals 5′ und im Bereich der mittleren Wand in den entsprechenden linken Bereich des Zuluftkanals 3′ strömt und hier den nicht näher dargestellten Filter analog der Ausführungsform nach Fig. 2 außenseitig beaufschlagt.6, the pivotable flap 9 'is pivoted about its pivot axis 8' into the vertical position to clean the filter. This results in a connection of the two channels 3 'and 5', with the air now, as shown in the direction of the arrow, from the left area of the exhaust air channel 5 'in the lower right area of the supply air channel 3', from there via the fan 4 in the right area of the exhaust air duct 5 'and in the area of the middle wall flows into the corresponding left area of the supply air duct 3' and here acts on the outside of the filter, not shown, analogously to the embodiment according to FIG. 2.

Bei der Ausführungsform nach Fig. 7 und 8 kreuzen sich wiederum der Zuluftkanal 3˝ und der Abluftkanal 5˝ in Bereich der gemeinsamen Wand 7. Hierbei sind der Zuluftkanal 3˝ und der Abluftkanal 5˝ im Querschnitt jeweils rechteckig ausgebildet. Statt der bei der Bauform nach Fig. 5 und 6 eingesetzten schwenkbaren Klappe 9′ findet bei der Ausführungsform nach Fig. 7 und 8 wiederum ein Schieber 10′ Anwendung, welcher aus einem waagrechten Rechteckbereich 13 und einem dazu oberhalb und unterhalb diagonal verlaufenden senkrechten Rechteckbereich 14 besteht.In the embodiment according to FIGS. 7 and 8, the supply air duct 3˝ and the exhaust air duct 5˝ in turn intersect in the region of the common wall 7. Here, the supply air duct 3˝ and the exhaust air duct 5˝ are each rectangular in cross section. Instead of the pivotable flap 9 'used in the design according to FIGS. 5 and 6, in the embodiment according to FIGS. 7 and 8 again a slide 10' is used, which consists of a horizontal rectangular area 13 and a perpendicular rectangular area 14 running above and below it diagonally consists.

Fig. 7 definiert hierbei die Arbeitsstellung, d. h. der Zuluftkanal 3˝ ist von dem Abluftkanal 5˝ getrennt, wobei der nicht näher dargestellte Filter seine Reinigungsfunktion übernimmt. Soll nun der Filter seinerseits gereinigt werden, so wird nach Fig. 8 durch Bewegen des Schiebers 10′ der waagrecht verlaufende Rechteckbereich 13 aus dem Bereich der gemeinsamen Wand 7 herausgeschoben und der senkrecht verlaufende Rechteckbereich 14 des Schiebers 10˝ in seiner Arbeitsstellung eingeschoben, wobei analog der Bauform nach Fig. 6 die beiden Kanäle 3˝ und 5˝ so miteinander verbunden werden, daß der Filter von außen eine Beaufschlagung erfährt und damit eine Reinigungswirkung gegeben ist.7 defines the working position, ie the supply air duct 3kanal is separated from the exhaust air duct 5˝, the filter, not shown, taking on its cleaning function. If the filter is to be cleaned in turn, 8 by moving the slider 10 'of the horizontally extending rectangular area 13 is pushed out of the area of the common wall 7 and the vertically extending rectangular area 14 of the slider 10' is inserted in its working position, analogously to the design according to FIG. 6, the two Channels 3˝ and 5˝ are connected to each other in such a way that the filter is acted on from the outside, thus providing a cleaning effect.

Dadurch, daß der Zuluftkanal und der Abluftkanal eine gemeinsame Wand aufweisen, welche in zwei Stellungen überführbar ist, ist erfindungsgemäß bei allein Bauformen die einfache Möglichkeit gegeben, auch kurzzeitig den zwischen dem Ansaugkanal und dem Zuluftkanal angeordneten Filter zu reinigen. Die Anordnung ist einfach aufgebaut und nahezu wartungsfrei.Characterized in that the supply air duct and the exhaust air duct have a common wall, which can be moved into two positions, the simple possibility according to the invention is given in the case of designs alone to also briefly clean the filter arranged between the intake duct and the supply air duct. The arrangement is simple and almost maintenance-free.
