Abstract
Filterelement (10) zur stirnseitigen Anströmung, bestehend aus einer Mehrzahl von zickzackförmig gefalteten Filtermedien (1, 2, 3), dadurch gekennzeichnet, dass die Filtermedien (1, 2, 3) an den Faltenenden abwechselnd miteinander verklebt sind und die nicht verklebten Enden der Filtermedien untereinander einen Abstand von mindestens der halben Faltenbreite aufweisen.Filter element (10) for the frontal flow, consisting of a plurality of zigzag folded filter media (1, 2, 3), characterized in that the filter media (1, 2, 3) are alternately glued together at the fold ends and the non-bonded ends of the Filter media with each other have a distance of at least half the fold width.
Description
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung betrifft ein Filterelement nach der Gattung des Patentanspruchs 1.The present invention relates to a filter element according to the preamble of
Hintergrund der Erfindung, Stand der TechnikBackground of the Invention, Prior Art
Filterelemente zur stirnseitigen Anströmung sind hinlänglich bekannt. Diese Filter sind z. B. aus Filterlagen gewickelt, die abwechselnd flach und wellenförmig ausgebildet sind. Hierdurch entstehen Kanäle, die durch einen wechselseitigen Verschluß eine Durchströmung des Filtermediums erzwingen. Danach tritt das zu filternde Medium durch stirnseitig offene Kanäle auf der Eintrittsseite des Filtlers ein und wechselt innerhalb des Filterelementes in Kanäle, die abströmseitig geöffnet und den Einströmkanälen benachbart sind. Dadurch findet eine Filterung des Fluids statt.Filter elements for the frontal flow are well known. These filters are z. B. from filter layers, which are alternately flat and wavy. This creates channels that enforce a flow through the filter medium by a mutual closure. Thereafter, the medium to be filtered enters through the front side open channels on the inlet side of the filter and changes within the filter element into channels which are open downstream and adjacent to the inflow channels. As a result, a filtering of the fluid takes place.
Ziel einer solchen Filtergestaltung ist es, den Einbauraum für das Filterelement so weit wie möglich zu verringern. Dabei bilden die Stirnseiten des Filterelementes eine Anströmseite und eine Abströmseite. Die Kanäle, die mit der Anströmseite verbunden sind, bilden die Rohseite des Filters und die abströmseitigen die Reinseite. Daher können solche Filter sehr kompakt, z. B. als sogenannter Inlinefilter in Rohrleitungen eingebaut werden.The aim of such a filter design is to reduce the installation space for the filter element as much as possible. The end faces of the filter element form an inflow side and an outflow side. The channels, which are connected to the upstream side, form the raw side of the filter and the downstream side of the clean side. Therefore, such filters can be very compact, z. B. be installed as a so-called inline filter in pipelines.
Gleichzeitig soll die Filterkapazität weitestmöglich gesteigert werden. Dies ist jedoch bei wellenförmiger Ausführung der Filterlagen nur in begrenztem Maße möglich. Es hat sich nämlich gezeigt, dass die zulaufenden Kanäle im Bereich der Berührung zwischen der wellenförmigen Filterlage mit der flachen Filterlage wenig durchströmt werden, so dass das Filtermedium in diesen Teilen weniger mit Partikeln beaufschlagt wird als in anderen. Durch die ungleichmäßige Beladung des Filtermediums ist das Standzeitende des Filters, welches durch den an ihm anliegenden Druckabfall bestimmt ist, bereits zu einem Zeitpunkt erreicht, bei dem Teile des Filtermediums die Grenzbeladung noch nicht erreicht haben.At the same time, the filter capacity should be increased as much as possible. However, this is only possible to a limited extent when the filter layers are wavy. It has been shown that the inflowing channels in the area of contact between the wave-shaped filter layer with the flat filter layer are flowed through little, so that the filter medium is less exposed to particles in these parts than in others. Due to the uneven loading of the filter medium, the service life end of the filter, which is determined by the pressure drop applied to it, has already been reached at a time at which parts of the filter medium have not yet reached the limit load.
Es ist weiterhin z. B. aus der
Derartige Filter sind jedoch teuer in der Herstellung. Außerdem ist an der Filterung des Fluids nur die Hälfte der verwendeten Lagen beteiligt. Dadurch ist eine Optimierung des Verhältnisses zwischen Bauraum und Filterfläche nicht gegeben.However, such filters are expensive to manufacture. In addition, only half of the layers used are involved in filtering the fluid. As a result, an optimization of the ratio between space and filter surface is not given.

Zusammenfassung der ErfindungSummary of the invention
Es ist daher die Aufgabe der vorliegenden Erfindung, die genannten Nachteile des Standes der Technik zu vermeiden und ein Filterelement zur stirnseitigen Anströmung bereit zu stellen, das kostengünstig in der Herstellung ist und eine optimale Filterfläche und -kapazität im Verhältnis zum Bauvolumen aufweist.It is therefore an object of the present invention to avoid the disadvantages of the prior art mentioned and to provide a filter element to the frontal flow, which is inexpensive to manufacture and has an optimal filter area and capacity in relation to the volume of construction.
Diese und weitere Aufgaben werden durch das Filterelement nach Anspruch 1 gelöst.These and other objects are achieved by the filter element according to

Detaillierte Beschreibung der AusführungsbeispieleDetailed description of the embodiments
Auf diese Weise entstehen Kanäle, die von dem zu filternden Fluid, bspw. Luft, durchströmt werden.In this way, channels are formed, which are traversed by the fluid to be filtered, for example. Air.
Das gesamte Balgpaket muss längsseitig mit einer umschliessenden Wandung verklebt sein.The entire bellows package must be glued along the side with a surrounding wall.
Die Stabilisierung der Falten kann beispielsweise durch ein aufgeklebtes Gitter an den Faltenenden erfolgen. Diese Art der Stabilisierung ist in
Ein wesentlicher Vorteil des erfindungsgemässen Filterelements liegt darin, dass ein deutlich kleinerer Einbauraum bei vergleichbarer Filterfläche als bisher erreicht wird. Weiterhin ist vorteilhaft, dass die erfindungsgemässen Filterelemente mittels Standardverfahren hergestellt werden können.A significant advantage of the inventive filter element is that a much smaller installation space is achieved with a comparable filter surface than before. Furthermore, it is advantageous that the filter elements according to the invention can be produced by standard methods.
