Technisches GebietTechnical area
Die Erfindung betrifft ein konzentrisches Filterelement nach den Merkmalen des Oberbegriffes des unabhängigen Anspruches 1.The The invention relates to a concentric filter element according to the features the generic term of the independent Claim 1.
Ein
solches Filterelement ist aus der
Es
ist ferner aus der
Diese Metallstreifen werden in einer entsprechend gestalteten Vorrichtung zu einem Rohr geformt und an den sich überlappenden Kanten miteinander verbunden.These Metal strips are in a correspondingly designed device formed into a tube and at the overlapping edges together connected.
Ebenso
zeigt die
Die Verfahren zur Herstellung solcher Rohrzargen sind sehr aufwendig und kostenintensiv.The Methods for producing such pipe sections are very expensive and costly.
Der Erfindung liegt daher die Aufgabe zugrunde, ein konzentrisches Filterelement zu schaffen, welches innerhalb des Filtermediums einen Stützkörper aufweist, wobei dieser Stützkörper eine Kunststoff- oder Metallhelix ist. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.Of the The invention is therefore based on the object, a concentric filter element to provide which has a support body within the filter medium, wherein this support body is a plastic or metal helix is. This task is characterized by the characterizing Characteristics of claim 1 solved.
Offenbarung der Erfindungepiphany the invention
Der wesentliche Vorteil der Erfindung liegt darin, dass der Stützkörper nach Art einer Druckfeder hergestellt werden kann. Die Federwindungen weisen einen bestimmten, vordefinierten Abstand auf. Diese Feder kann in einer einfachen Federwickeleinrichtung endlos produziert und bei Bedarf auf die entsprechende Länge abgeschnitten werden. Aufgrund der feder wirksamen Eigenschaften kann eine gewisse Längentoleranz des Filtermediums überbrückt werden, so dass eine optimale Anpassung des Stützkörpers an die Länge des Filtermediums gewährleistet ist.Of the essential advantage of the invention is that the support body after Type of compression spring can be made. The spring coils have a certain predefined distance. This spring can be produced endlessly in a simple spring winding device and cut to the appropriate length if necessary. Due to the spring-active properties, a certain length tolerance of the filter medium can be bridged, so that an optimal adaptation of the support body to the length of the Filter medium guaranteed is.
Ein weiterer Vorteil der Erfindung liegt darin, dass der Materialverbrauch für den Stützkörper sehr gering ist. Es sind im Stützkörper keine Durchbrüche für das Fluid erforderlich. Die Abstützung des Filtermediums wird durch eine entsprechend gewählte Steigung definiert.One Another advantage of the invention is that the material consumption for the Supporting body very low is. There are no in the support body Breakthroughs for the fluid required. The support of the filter medium is through a correspondingly selected slope Are defined.
Gemäß einer Ausgestaltung der Erfindung weist die Kunststoff- oder Metallhelix einen runden, ovalen oder rechteckigen Querschnitt auf. Im Extremfall kann der Querschnitt derart gestaltet sein, dass es sich um ein Flachmaterial handelt, dessen Materialstärke um ein Vielfaches geringer ist als die Breite des gewickelten Materials. Die Verwendung einer Helix mit einem ovalen Querschnitt hat den Vorteil, dass bei entsprechender Anordnung die Anlagefläche der Helix an das Filtermedium gegenüber einem runden Querschnitt vergrößert werden kann.According to one Embodiment of the invention has the plastic or metal helix a round, oval or rectangular cross section. In extreme cases the cross-section can be designed such that it is a Flat material is, whose material thickness is much lower is the width of the wound material. The use of a Helix with an oval cross-section has the advantage that with appropriate Arrangement of the contact surface the helix to the filter medium opposite a round cross-section be enlarged can.
Weiterbildungsgemäß ist die Kunststoff- oder Metallhelix an den Stirnseitenenden mit den Endscheiben verbunden oder in die Endscheiben eingebettet. Die Verbindung erfolgt beispielsweise über eine Klebeverbindung. Die Einbettung kann auch bei dem Herstellprozess zur Herstellung der Endscheibe erfolgen. Falls diese Endscheibe ein thermoplastisches Kunststoffteil ist, kann eine Metallhelix bereits beim Fertigungsvorgang der Endscheibe an ihrem Ende in den Kunststoff eingebettet werden. Neben der punktuellen Befestigung der Helix an der Endscheibe besteht auch die Möglichkeit, diese über eine oder mehrere anliegende Endwindungen über einen größeren Winkelbereich, insbesondere größer 90° mit der Endscheibe zu verbinden. Damit wird eine höhere Stabilität zwischen Stützkörper und Endscheibe erzielt. Sofern eine Kunststoffhelix zur Anwendung gelangt, kann diese im Extrudierverfahren hergestellt werden. Beim Extrudiervorgang wird Kunststoff aus einer Düse auf einen Übergabezylinder gespritzt, in einem kontinuierlichen Prozess wird dabei dieser Stützkörper hergestellt.Training is the Plastic or metal helix at the front ends with the end discs connected or embedded in the end plates. The connection is made for example, via a Adhesive bond. The embedding can also in the manufacturing process done for the production of the end plate. If this end disc A thermoplastic part is a metal helix already in the manufacturing process of the end plate at its end in the Be embedded plastic. In addition to the selective attachment the helix at the end disc also has the possibility of this over one or several adjacent Endwindungen over a larger angular range, in particular greater than 90 ° with the Connect end plate. This will provide a higher stability between Supporting body and End disc achieved. If a plastic helix is used, this can be produced by extrusion. During the extrusion process will plastic from a nozzle on a transfer cylinder sprayed, this support body is produced in a continuous process.
In einer alternativen Ausgestaltung befindet sich ein Stützkörper am Außenumfang des Filtermediums. Dieser dient dazu, nach außen wirkende Kräfte, beispielsweise bei einer Durchströmung des Filtermediums von innen nach außen, aufzufangen. Er kann aber auch als Griffschutz oder Sicherungselement zur Vermeidung der Beschädigung des Filterelementes dienen.Located in an alternative embodiment a support body on the outer circumference of the filter medium. This serves to absorb outward-acting forces, for example during a flow through the filter medium from the inside to the outside. But it can also serve as a grip protection or security element to avoid damaging the filter element.
Das Filterelement wird in einer bevorzugten Anwendung in eine Filtereinrichtung eingebaut und dient zur Filtrierung von Flüssigkeit oder Gasen, wobei die Filtereinrichtung aus einem konzentrischen Gehäuse besteht und das Filterelement in diesem Gehäuse angeordnet ist, und wobei das Filterelement einen inneren und/oder äußeren Stützkörper in Form einer gewickelten Kunststoff- oder Metallhelix aufweist.The Filter element is in a preferred application in a filter device installed and used for filtration of liquid or gases, wherein the filter device consists of a concentric housing and the filter element is disposed in this housing, and wherein the filter element an inner and / or outer support body in the form of a wound Plastic or metal helix has.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und der Zeichnung hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and further features of preferred embodiments of the invention go out from the claims also apparent from the description and the drawing, wherein the individual Features for each alone or in the form of subcombinations the embodiment of the invention and in other fields be realized and advantageous also for protectable versions can represent for the protection is claimed here.
