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 a blow-out 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 out the contaminants in the ambient air that arise during work in the form of grinding dust, welding fumes or the like. It is usually endeavored to vacuum these contaminants as close as possible to their place of origin and thus to render them harmless. In the case of welding smoke, this is done by 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, such extraction in the immediate vicinity of the point of origin is not possible for spatial and / or technical reasons, so that the contaminants are widely distributed in the room air. In order to ensure better indoor air in this case, too, so-called stratified filtering has often been used in recent times. In this method, room air filters of the type mentioned at the outset are drawn up at one or more points in the room, which suck in the room air contaminated with impurities approximately at the level of the head of the people working in the room, using the filter device located in the housing of the room air filter, to remove the impurities and finally the cleaned room air is released 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.
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 an object of the invention to develop the room air filter of the type mentioned at the outset 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 achieve this object, the invention proposes, starting from a room air filter of the type mentioned, 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 are each one in the longitudinal direction of the tube extending lateral suction slot, in the suction cross-section adjustable louvres 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 produces instead of just one, from top to bottom flow field, several horizontally directed flow fields, which can suck in the contaminated room air at any height and with adjustable intensity near its origin. 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 turning the end sections of the intake pipes, it is possible to combine the flow fields that are formed, which are directed in the direction of the intake slots, e.g. to run more or less parallel to each other to intensify the suction effect, or to 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 expedient if the tubes are designed to be foldable, pivotable and / or telescopic. This results in further possibilities for adapting the flow fields that are formed 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 formed entirely or partially 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 which can be moved on all sides and with handles for displacement. This makes it possible in a simple manner to move or twist the room air filter at any location in any direction in order to get as close as possible to the possible sources of contamination.
