Description

Die Erfindung bezieht sich auf einen Vorabscheider für die An- bzw. Absaugöffnung von Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. , wobei in dem Vorabscheider zwei hintereinander angeordnete, voneinander beabstandete Reihen vertikal oder horizontal gerichteter, voneinander beabstandeter Prallsegmente vorgesehen sind, und wobei die Prallsegmente der einen Reihe versetzt zu den Prallsegmenten der anderen Reihe angeordnet sind.The invention relates to a pre-separator for the intake and exhaust of spray mist extraction systems, paint shops and the like. wherein in the pre-separator two successively arranged, spaced-apart rows of vertically or horizontally oriented, spaced-apart impact segments are provided, and wherein the impact segments of the one row offset from the impact segments of the other row are arranged.

Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. weisen an ihren An- bzw. Absaugöffnungen ein Filtervlies auf, an dem sich die in der Luft befindlichen Farb- und Lackpartikel absetzen bzw. in dem diese herausgefiltert werden. Dieses Filtervlies ist relativ schnell verunreinigt, so dass dasselbe gegen ein neues Filtervlies ausgetauscht werden muss. Da das Filtervlies zudem ein Einwegartikel ist, entstehen dem Betreiber von Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. durch das relativ häufige Auswechseln des Filtervlieses sehr hohe Material-, Wartungs- und Entsorgungskosten.Spray mist extraction systems, paint shops and the like. have at their arrival or suction on a filter fleece on which settle the color and paint particles located in the air or in which they are filtered out. This filter fleece is relatively quickly contaminated, so that the same must be replaced with a new filter fleece. Since the filter fleece is also a disposable article, the operator of spray mist extraction systems, paint shops and the like arise. Due to the relatively frequent replacement of the filter fleece very high material, maintenance and disposal costs.

Eine Einrichtung zum Absaugen von Farbnebel und Dämpfen im Bereich von Arbeitsplätzen, insbesondere im Bereich von Farbspritzanlagen, mit einem Vorabscheidesystem mit ein- oder mehrfacher Umlenkung und einem rohrförmigen Filter ist beispielsweise in der DE 297 05 487 U1 beschrieben. Dabei deckt das Vorabscheidesystem den Filter ganz gegen den abzusaugenden Raum hin ab.A device for extracting paint mist and vapors in the field of workplaces, in particular in the field of paint spraying, with a pre-separation system with single or multiple deflection and a tubular filter is for example in the DE 297 05 487 U1 described. The pre-separation system covers the filter completely against the room to be extracted.

Ein Kondensatabscheider ist aus der EP 1 080 788 A1 bekannt, der eine Kühlzone einer mindestens eine Lackierkabine, einen beheizten Trockner zum Trocknen lackierter Gegenstände sowie eine dem Trockner in Durchlaufrichtung der Gegenstände nachgeordnete Kühlzone zum Abkühlen der lackierten und getrockneten Gegenstände aufweisenden Lackieranlage beschreibt.A condensate separator is out of the EP 1 080 788 A1 It is known to describe a cooling zone of at least one painting booth, a heated dryer for drying painted articles, and a painting zone downstream of the dryer in the passage direction of the articles for cooling the painted and dried articles.

Aus der DE 196 03 689 A1 geht ein Abscheider zur Ausscheidung von Partikeln aus gasförmigen Fluiden wie Kühlfluiden, Ölnebeln, Fettnebeln hervor, der vorzugsweise aus zumindest zwei sich in gegenüberliegende Reihen angeordneten, im Querschnitt offenen rinnenförmigen ersten und zweiten Profilteilen gebildet ist.From the DE 196 03 689 A1 a separator for the separation of particles of gaseous fluids such as cooling fluids, oil mists, greases out, which is preferably formed from at least two arranged in opposite rows, open in cross-section channel-shaped first and second profile parts.

Der Erfindung liegt die Aufgabe zugrunde, einen Vorabscheider der angegebenen Gattung zu schaffen, mit dem die Material-, Wartungs- und Entsorgungskosten für Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. wesentlich reduziert werden.The invention has for its object to provide a pre-separator of the type specified, with the material, maintenance and disposal costs for spray extraction systems, paint shops u.dgl. be significantly reduced.

Diese Aufgabe wird erfindungsgemäß durch einen Vorabscheider mit den Kennzeichnungsmerkmalen des Patentanspruchs 1 gelöst.This object is achieved by a pre-separator with the characterizing features of claim 1.

Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.

Der erfindungsgemäße Vorabscheider zeichnet sich insbesondere dadurch aus, dass durch die zwangsgeführte An- bzw. Absaugung durch den labyrinthartigen Vorabscheider sich der größte Anteil der sich in der Luft befindlichen Farb- und Lackpartikel an den Prallsegmenten absetzt und dadurch lediglich ein sehr geringer Anteil der Farb- und Lackpartikel bis zu dem Filtervlies vordringt. Das Wechseln des Filtervlieses ist daher wesentlich seltener notwendig. Es entsteht eine Ersparnis von bis zu 80%.The pre-separator according to the invention is characterized in particular by the fact that the forcibly guided suction or suction through the labyrinthine pre-separator deposits the largest proportion of the color and paint particles in the air at the impact segments and thereby only a very small proportion of the ink particles. and paint particles penetrates up to the filter fleece. Changing the filter fleece is therefore much less necessary. There is a savings of up to 80%.

Der Vorabscheider muss erst beim Wechseln des Filtervlieses gereinigt werden. Dieses Reinigen erfolgt relativ mühelos, da durch das verwendete Material eine sehr geringe Haftung der Farb- und Lackpartikel gewährleistet ist und diese sich sehr leicht ablösen bzw. abziehen lassen.The pre-separator must first be cleaned when changing the filter fleece. This cleaning is relatively easy, since the material used a very low adhesion of the paint and paint particles is guaranteed and they can be easily peel or peel off.

Das in den Figuren dargestellte Ausführungsbeispiel eines Vorabscheiders 1, der für die An- bzw. Absaugöffnung 2 von Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. 3 vorgesehen ist, besteht im wesentlichen aus einem Grundrahmen 4 mit mindestens einer Öffnung 5 (im dargestellten Ausführungsbeispiel sind zwei Öffnungen 5 vorgesehen), in den bzw. in die jeweils zwei hintereinander angeordnete Einzelrahmen 6, 7 lösbar einsetzbar sind. In den Einzelrahmen 6, 7 sind jeweils eine Reihe 8, 9 von sich von einem Rahmenteil 10 zu dem dem Rahmenteil 10 gegenüberliegenden Rahmenteil 11 erstreckenden vertikal oder horizontale gerichteten, voneinander beabstandeten Prallsegmenten 12 vorgesehen. Dabei sind die Prallsegmente 12 der einen Reihe 8 des einen Einzelrahmens 6 mit Abstand und versetzt zu den Prallsegmenten 12 der anderen Reihe 9 des anderen Einzelrahmens 7 angeordnet.The illustrated in the figures embodiment of a pre-separator 1, the like for the intake or exhaust 2 of spray extraction systems, paint shops and the like. 3 is provided, consists essentially of a base frame 4 with at least one opening 5 (in the illustrated embodiment, two openings 5 are provided), in which or in the two consecutively arranged single frame 6, 7 are detachably insertable. In the single frame 6, 7 are each a row 8, 9 of itself from a frame part 10 to the frame part 10 opposite the frame part 11 extending vertically or horizontally directed, spaced-apart baffle segments 12 are provided. In this case, the baffle segments 12 of a row 8 of a single frame 6 are arranged at a distance and offset from the baffle segments 12 of the other row 9 of the other single frame 7.

Der Grundrahmen 4 weist in der Öffnung 5 bzw. den Öffnungen 5 auf seiner zu der An- bzw. Absaugöffnung 2 der jeweiligen Sprühnebel-Absauganlage, Lackieranlage u.dgl. 3, an der das Filtervlies 13 vorgesehen ist, gerichteten Seite 14 eine einstückig angeformte Anschlagkante 15 für die Einzelrahmen 6, 7 auf. Zum Wechseln des Filtervlieses 13 müssen bei diesem Ausführungsbeispiel lediglich die beiden Einzelrahmen 6, 7 entnommen werden, woraufhin das Filtervlies 13 frei zugänglich ist.The base frame 4 has in the opening 5 and the openings 5 on its to the intake or exhaust 2 of the respective spray extraction system, paint shop u.dgl. 3, on which the filter fleece 13 is provided, directed side 14 an integrally formed stop edge 15 for the single frame 6, 7. To change the filter fleece 13, only the two individual frames 6, 7 must be removed in this embodiment, whereupon the filter fleece 13 is freely accessible.

Bei einem weiteren, nicht dargestellten Ausführungsbeispiel des Vorabscheiders 1 besteht derselbe ebenfalls im wesentlichen aus einem Grundrahmen 4 mit mindestens einer Öffnung 5. In dem Grundrahmen 4 bzw. in der Öffnung 5 sind hierbei direkt zwei hintereinander angeordnete, voneinander beabstandete Reihen 8, 9 von sich von einem Rahmenteil 16 zu dem dem Rahmenteil 16 gegenüberliegenden Rahmenteil 17 erstreckenden vertikal oder horizontal gerichteten, voneinander beabstandeten Prallsegmenten 12 vorgesehen. Die Prallsegmente 12 der einen Reihe 8 sind auch hierbei versetzt zu den Prallsegmenten 12 der anderen Reihe 9 angeordnet. Zum Wechseln des Filtervlieses 13 muss bei diesem Ausführungsbeispiel der gesamte Vorabscheider 1 entnommen werden, woraufhin das Filtervlies 13 frei zugänglich ist.In a further, not shown embodiment of the pre-separator 1, the same also consists essentially of a base frame 4 with at least one opening 5. In the base frame 4 and in the opening 5 are in this case two consecutively arranged, spaced-apart rows 8, 9th provided by a frame member 16 to the frame member 16 opposite frame member 17 extending vertically or horizontally directed, spaced-apart impact segments 12. The baffle segments 12 of a row 8 are here also arranged offset to the baffle segments 12 of the other row 9. To change the filter fleece 13, the entire pre-separator 1 must be removed in this embodiment, whereupon the filter fleece 13 is freely accessible.

Die Prallsegmente 12 sämtlicher Ausführungsbeispiele sind im Querschnitt vorzugsweise halbrohrförmig ausgebildet, wobei die Innenmäntel 18 der halbrohrförmigen Prallsegmente 12 der hintereinander angeordneten Reihen 8, 9 sich jeweils gegenüberliegen.The baffle segments 12 of all embodiments are preferably semi-tubular in cross-section, wherein the inner shells 18 of the semi-tubular baffle segments 12 of the successively arranged rows 8, 9 each lie opposite one another.

Wie bereits erwähnt setzen sich durch die zwangsgeführte An- bzw. Absaugung durch den labyrinthartigen Vorabscheider der größte Anteil der sich in der Luft befindlichen Farb- und Lackpartikel an den Prallsegmenten ab, wodurch lediglich ein sehr geringer Anteil der Farb- und Lackpartikel bis zu dem Filtervlies vordringt. Das Wechseln des Filtervlieses ist daher relativ selten erforderlich.As already mentioned, the forcibly guided intake and exhaust through the labyrinthine pre-separator leaves the largest proportion of the paint and lacquer particles in the air on the impact segments, as a result of which only a very small proportion of the paint and lacquer particles reach the filter fleece forced out. Changing the filter fleece is therefore relatively rarely required.

Sämtliche Teile des Vorabscheiders 1 bestehen aus einem Kunststoff, wobei der Kunststoff die Eigenschaft aufweist, dass Farben und Lacke nur ablösbar bzw. abziehbar haften. Dadurch ist eine sehr einfache Reinigung des Vorabscheiders 1 möglich, da sich die gebildete Farb- und Lackpartikelschicht leicht abziehen lässt. Der Kunststoff kann beispielsweise ein Polyethylen (PE), Polypropylen (PP) oder auch sonstiges sein.All parts of the pre-separator 1 are made of a plastic, wherein the plastic has the property that paints and varnishes adhere only removable or peelable. As a result, a very simple cleaning of the pre-separator 1 is possible because the color and paint particle layer formed can be easily removed. The plastic may be, for example, a polyethylene (PE), polypropylene (PP) or else.

Der erfindungsgemäße Vorabscheider 1 kann in neuen Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. 3 direkt eingebaut oder bei vorhandenen Sprühnebel-Absauganlagen, Lackieranlagen u.dgl. 3 nachgerüstet werden.The pre-separator 1 according to the invention can be in new spray extraction systems, paint shops u.dgl. 3 directly installed or in existing spray mist extraction systems, paint shops and the like. 3 be retrofitted.
