Description

Die Erfindung betrifft einen Raumluftfilter für die Filterung der Luft in Räumlichkeiten, mit einem auf dem Boden der Räumlichkeit verfahrbaren Gehäuse, welches eine Filtereinrichtung und ein Sauggebläse enthält und mit mindestens einem Ansaugkamin mit verstellbarer Ansaugöffnung und einer Ausblasöffnung versehen ist.The invention relates to a room air filter for filtering the air in rooms, with a movable housing on the floor of the room, which contains a filter device and a suction fan and is provided with at least one suction chimney with adjustable suction opening and an exhaust opening.

In vielen Produktionsbetrieben ist es aus gesundheitlichen Gründen notwendig, die bei der Arbeit entstehenden Verunreinigungen der Raumluft in Form von Schleifstaub, Schweißrauch oder dgl. aus der Raumluft abzufiltern. Dabei ist man normalerweise bemüht, diese Verunreinigungen möglichst nahe an deren Entstehungsort abzusaugen und damit unschädlich zu machen. Im Falle von Schweißrauch erfolgt dieses durch punktuelle Absaugung.In many production plants, for health reasons, it is necessary to filter the indoor air contaminants in the form of grinding dust, welding smoke or the like. In doing so, efforts are normally made to suck off these impurities as close as possible to their place of origin and thus render them harmless. In the case of welding fumes, this is done through selective extraction.

In vielen Fällen ist allerdings aus räumlichen und/oder arbeitstechnischen Gründen eine solche Absaugung in unmittelbarer Nähe des Entstehungsortes nicht möglich, sodass sich die Verunreinigungen weiträumig in der Raumluft verteilen. Um auch in diesem Fall für eine bessere Raumluft zu sorgen, arbeitet man in der jüngeren Zeit vielfach mit einer sogenannten Schichtfilterung. Bei diesem Verfahren werden an einer oder mehreren Stellen des Raumes Raumluftfilter der eingangs genannten Art aufgestellt, die die mit Verunreinigungen belastete Raumluft etwa in Kopfhöhe der in dem Raum tätigen Menschen ansaugen, mithilfe der in dem Gehäuse des Raumluftfilters befindlichen Filtereinrichtung von den Verunreinigungen befreien und abschließend die gereinigte Raumluft wieder in den Raum abgegeben.In many cases, however, for reasons of space and / or work technology, such an extraction is not possible in the immediate vicinity of the point of origin, so that the contaminants are widely distributed in the room air. In order to ensure better room air in this case too, so-called layer filtering has been used in recent times. In this method, room air filters of the type mentioned at the beginning are set up at one or more points in the room, which suck in the room air contaminated with contaminants at about head height of the people working in the room, with the aid of the filter device located in the housing of the room air filter from the contaminants and finally the cleaned room air is released back into the room.

Dieses Verfahren arbeitet dann besonders effektiv, wenn es gelingt, die Raumluft dort an zu saugen, wo sie am stärksten mit Verunreinigungen belastet ist. Dies ist mit dem Stand der Technik (vgl. DE 10 2015 112 977 A1 ) bekannten Raumluftfilter der angegebenen Art allerdings nicht ohne weiteres möglich, weil sich oberhalb der nach oben gerichteten Ansaugöffnung des Ansaugkamines ein im Prinzip trichterförmiges Druckgefälle und ein an dieses Druckgefälle angepasstes, von oben nach unten gerichtetes Strömungsfeld ergeben, so dass z.B. seitlich vom Standort des Raumluftfilters angeordnete Quellen der Verunreinigung kaum erreicht werden können.This process works particularly effectively when it is possible to suck in the room air where it is most heavily contaminated. This is with the state of the art (cf. DE 10 2015 112 977 A1 ) known room air filter of the specified type, however, not readily possible because above the upward suction opening of the suction chimney there is a basically funnel-shaped pressure gradient and a flow field adapted to this pressure gradient, directed from top to bottom, so that, for example, laterally from the location of the room air filter arranged sources of pollution can hardly be reached.

Es ist deshalb Aufgabe der Erfindung, den Raumluftfilter der eingangs genannten Art dahingehend weiterzubilden, dass sein Ansaugbereich besser an unterschiedliche örtliche Gegebenheiten angepasst werden kann.It is therefore the object of the invention to develop the room air filter of the type mentioned at the beginning in such a way that its suction area can be better adapted to different local conditions.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von einem Raumluftfilter der eingangs genannten Art vor, dass das Gehäuse zwei oder mehr Ansaugkamine aufweist, die mit Abstand zueinander an dem Gehäuse befestigt sind und jeweils als einstellbare Rohre ausgebildet sind, deren Endabschnitte jeweils einen sich in Längsrichtung des Rohres erstreckenden seitlichen Ansaugschlitz aufweisen, in dessen Saugquerschnitt verstellbare Jalousieklappen angeordnet sind.To solve this problem, the invention proposes, based on a room air filter of the type mentioned at the beginning, that the housing has two or more suction chimneys which are attached to the housing at a distance from one another and are each designed as adjustable tubes, the end sections of which each extend one in the longitudinal direction of the pipe extending lateral suction slot, in whose suction cross-section adjustable louvre flaps are arranged.

Der Raumluftfilter gemäß der Erfindung erzeugt anstelle von nur einem, von oben nach unten gerichteten Strömungsfeld mehrere horizontal gerichtete Strömungsfelder, die in beliebiger Höhe und mit verstellbarer Intensität die mit Verunreinigungen belastete Raumluft in der Nähe von deren Entstehungsort ansaugen können. Darüber hinaus kann durch Verstellen der Jalousieklappe in gewissem Umfange auch die Richtung dieser Strömungsfelder in vertikaler Richtung beeinflusst werden.The room air filter according to the invention generates, instead of just one flow field directed from top to bottom, several horizontally directed flow fields that can suck in the contaminated air near the point of origin at any height and with adjustable intensity. In addition, the direction of these flow fields in the vertical direction can also be influenced to a certain extent by adjusting the louvre flap.

Eine besonders bevorzugte Ausführungsform der Erfindung sieht vor, dass zusätzlich die Endabschnitte der Rohre jeweils um ihre Längsachse verdrehbar ausgebildet sind.A particularly preferred embodiment of the invention provides that, in addition, the end sections of the tubes are each designed to be rotatable about their longitudinal axis.

Durch Verdrehen der Endabschnitte der Ansaugrohre ist es möglich, die sich ausbildenden Strömungsfelder, die in Richtung auf die Ansaugschlitze gerichtet sind, miteinander zu kombinieren, z.B. mehr oder weniger parallel zueinander verlaufen zu lassen, um die Ansaugwirkung zu intensivieren, oder divergierend verlaufen zu lassen, um den Ansaugbereich möglichst groß werden zu lassen.By rotating the end sections of the suction pipes, it is possible to combine the developing flow fields that are directed towards the suction slots, e.g. to let them run more or less parallel to one another in order to intensify the suction effect, or to let them run diverging, to make the suction area as large as possible.

Ebenso ist es zweckmäßig, wenn die Rohre klappbar schwenkbar und/oder teleskopierbar ausgebildet sind. Hierdurch ergeben sich weitere Möglichkeiten für die Anpassung der sich ausbildenden Strömungsfelder an die gegebenen Raumverhältnisse.It is also useful if the tubes are designed to be foldable, pivotable and / or telescopic. This results in further options for adapting the flow fields that develop to the given spatial conditions.

Zum gleichen Zweck kann es weiterhin vorteilhaft sein, wenn die Rohre ganz oder teilweise von Schläuchen gebildet werden.For the same purpose, it can also be advantageous if the tubes are entirely or partially formed by hoses.

Schließlich ist vorgesehen, dass das Gehäuse des Raumluftfilters mit einem allseitig verfahrbaren Rollenfahrwerk und mit Handgriffen zum Verschieben versehen ist. Hierdurch ist es auf einfache Weise möglich, den Raumluftfilter an jedem beliebigen Standort in jede Richtung zu verschieben oder zu verdrehen, um möglichst nahe an die möglichen Entstehungsorte von Verunreinigungen heranzukommen.Finally, it is provided that the housing of the room air filter is provided with a roller carriage that can be moved on all sides and with handles for moving it. This makes it possible in a simple manner to move or rotate the room air filter at any location in any direction in order to get as close as possible to the possible locations where contamination occurs.

Ein Ausführungsbeispiel der Erfindung wird im Folgenden anhand der beigefügten Zeichnungen erläutert. Es zeigen:

An exemplary embodiment of the invention is explained below with reference to the accompanying drawings. Show it:

A room air filter according to the invention in a front view;
Figure 2:

Figures 3a, 3b and 3c:

In der Zeichnung ist das Gehäuse des neuen Raumluftfilters mit dem Bezugszeichen 1 bezeichnet. Dieses Gehäuse 1 wird von einem allseitig verfahrbaren Rollenfahrwerk 2 getragen und ist mit Handgriffen 3 versehen, mit deren Hilfe das Gehäuse 3 auf dem Boden 4 einer Räumlichkeit beliebig verschoben und verdreht werden kann.In the drawing, the housing of the new room air filter is denoted by the reference number 1. This housing 1 is carried by an all-round movable roller carriage 2 and is provided with handles 3, with the aid of which the housing 3 can be moved and rotated as desired on the floor 4 of a room.

Im Innenraum des Gehäuses 1 befinden sich (nicht dargestellt) eine Filtervorrichtung und ein Sauggebläse. Dieses Sauggebläse saugt über zwei jeweils in ihrer Gesamtheit mit dem Bezugszeichen 5 bezeichnete Ansaugkamine Luft an, bewegt diese Luft durch die Filtereinheit und bläst die gefilterte Luft über eine am Gehäuse 1 befindliche Ausblasöffnung 9 in die Räumlichkeit aus.A filter device and a suction fan are located in the interior of the housing 1 (not shown). This suction fan sucks in air via two suction chimneys, each designated in their entirety with the reference number 5, moves this air through the filter unit and blows the filtered air out into the room via an exhaust opening 9 located on the housing 1.

Die Besonderheit der Erfindung besteht darin, dass an dem Gehäuse 1 mit Abstand zueinander zwei oder mehr nach oben verlaufende Ansaugkamine 5 vorgesehen sind, die mit dem Gehäuse 1 verbunden sind und jeweils als Basisabschnitte 6a und Ansaugrohr 6b ausgebildet sind. Dabei sind die Basisabschnitte 6a jeweils starr mit dem Gehäuse1 verbunden, während die Ansaugrohre 6b um ihre Längsachse verdrehbar mit den Basisabschnitten 6a verbunden sind. Weiterhin sind diese oben geschlossenen Ansaugrohre 6b jeweils seitlich mit einem sich in deren Längsrichtung erstreckenden Ansaugschlitz 7 versehen, in dessen Saugquerschnitt jeweils verstellbarer Jalousieklappen 8 angeordnet sind. Durch Verschwenken dieser Jalousieklappen 8 ist es möglich, die Größe des jeweiligen Saugquerschnittes einzustellen und die Richtung des sich vor dem Ansaugschlitz 7 ausbildenden Saugstromes zu beeinflussen.The special feature of the invention is that two or more upwardly extending suction chimneys 5 are provided on the housing 1 at a distance from one another, which are connected to the housing 1 and are each designed as base sections 6a and suction pipe 6b. The base sections 6a are each rigidly connected to the housing 1, while the suction pipes 6b are connected to the base sections 6a such that they can be rotated about their longitudinal axis. Furthermore, these suction pipes 6b, which are closed at the top, are each laterally provided with a suction slot 7 extending in their longitudinal direction, in the suction cross-section of which adjustable louvre flaps 8 are arranged. By pivoting these louvre flaps 8, it is possible to adjust the size of the respective suction cross-section and to influence the direction of the suction flow that forms in front of the suction slot 7.

Wie ohne weiteres ersichtlich ist, kann man durch Höhenverstellung und Verdrehung der Endabschnitte 6b der Ansaugkamine 5 und gegebenenfalls durch Verschwenken der in den an Saugschlitzen 7 befindlichen Jalousieklappen 8 den sich im Umgebungsbereich des Raumluftfilters ausbildenden Saugstrom sehr gut dem Bedarf entsprechend ausrichten.As is readily apparent, by adjusting the height and rotating the end sections 6b of the suction chimneys 5 and, if necessary, by pivoting the louvre flaps 8 located in the suction slots 7, the suction flow that forms in the vicinity of the room air filter can be adjusted very well as required.

Abweichend vom dargestellten Ausführungsbeispiel können die die Ansaugkamine 5 bildenden Rohre auch klappbar, schwenkbar und oder teleskopierbar ausgebildet sein. Schließlich ist es auch möglich, dass die einstellbaren Rohre ganz oder teilweise von ausreichend steifen Schläuchen gebildet werden.Notwithstanding the illustrated embodiment, the pipes forming the suction chimneys 5 can also be foldable, pivotable and / or Be designed to be telescopic. Finally, it is also possible for the adjustable tubes to be entirely or partially formed by sufficiently rigid hoses.
