Aus
der deutschen Offenlegungsschrift
Aufgabe der Erfindung ist es, eine Filtereinrichtung gemäß dem Oberbegriff des Anspruchs 1 zuschaffen, mit welcher die Reinigung des Prozessabwassers insbesondere in der industriellen Lackierung vereinfacht wird.task The invention is a filter device according to the preamble of the claim 1 zuschaffen, with which the cleaning of the process wastewater in particular in industrial painting is simplified.
Die Aufgabe ist bei einer Filtereinrichtung zum Filtern insbesondere von Lackabwasser, mit Filterelementen, die von dem Lackabwasser durchströmt werden, dadurch gelöst, dass die Filterelemente als Elektroden ausgeführt sind, die in dem Lackabwasser enthaltene Lackpartikel anziehen. Die Filterelemente können als Anoden oder Kathoden ausgeführt sein. Wesentlich ist, dass die Anziehung der Lackpartikel nach dem Prinzip der Elektrolyse beziehungsweise Elektrophorese erfolgt. Das Prinzip der Elektrophorese betrifft die Wanderung elektrisch geladener Teilchen in einem elektrischen Feld. Sie heißt bei negativ geladenen Teilchen auch Anaphorese, bei positiv geladenen Teilchen Kataphorese. Im Filterbetrieb wird an die Filterelemente, die vorzugsweise als Filterplatten ausgeführt sind, eine Spannung angelegt. Beim Durchströmen der Filterelemente mit Lackabwasser bleiben Lackpartikel und gegebenenfalls Verunreinigungen an den Filterelementen haften. Wenn die Filtereinrichtung voll ist, dann können die Filterelemente mit Druckluft abgeblasen werden. Dabei kann die elektrische Spannung solange aufrechterhalten bleiben, bis die Filterelemente vollständig abgeblasen sind. Die Filtereinrichtung dient zum Filtern von Lackabwasser und/oder von Phosphatierbädern (z.B. Filtrieren von Phophatschlamm aus einem Phosphatbad) und/oder von anderen Medien. Die Filtereinrichtung weist Ioden auf, so dass zum Filtern keine Filtertücher mehr gebraucht werden.The Task is in a filter device for filtering in particular of paint wastewater, with filter elements removed from the paint wastewater flows through be solved by in that the filter elements are designed as electrodes which are in the lacquer waste water tighten the paint particles contained. The filter elements can as Anodes or cathodes executed be. It is essential that the attraction of the paint particles after the Principle of electrolysis or electrophoresis takes place. The principle of electrophoresis relates to the migration of electrically charged Particles in an electric field. It is called with negatively charged particles also anaphoresis, with positively charged particles cataphoresis. In filter mode is applied to the filter elements, which are preferably designed as filter plates, a voltage applied. When flowing through the filter elements with Lackabwasser remain paint particles and possibly impurities adhere to the filter elements. When the filter device is full, then can the filter elements are blown off with compressed air. It can the electrical voltage is maintained until the filter elements Completely are blown off. The filter device is used for filtering paint wastewater and / or phosphating baths (e.g., filtering phosphate slurry from a phosphate bath) and / or from other media. The filter device has Ioden, so that the Do not filter filter cloths more needed.
Ein bevorzugtes Ausführungsbeispiel der Filtereinrichtung ist dadurch gekennzeichnet, dass die Filtereinrichtung zur Aufnahme der Filterelemente ein Hüllrohr umfasst, in welchem eine Anode und/oder eine Kathode vorgesehen sind/ist. Vorzugsweise erfolgt die Durchströmung der Filterelemente mit Lackabwasser senkrecht zu der Längsachse des Hüllrohrs. Vorzugsweise ist eine der Elektroden, zum Beispiel die Anode, feststehend ausgeführt. Die andere Elektrode, zum Beispiel die Kathode, ist relativ zu der Gegenelektrode bewegbar. Dadurch wird auf einfache Art und Weise ein Zusammenpressen der zwischen den Elektroden angeordneten Filterelemente ermöglicht.One preferred embodiment the filter device is characterized in that the filter device for receiving the filter elements comprises a cladding tube, in which an anode and / or a cathode are / is provided. Preferably the flow occurs the filter elements with paint wastewater perpendicular to the longitudinal axis of the cladding tube. Preferably, one of the electrodes, for example the anode, is stationary executed. The other electrode, for example the cathode, is relative to the counter electrode movable. This will be a simple way of compressing allows the arranged between the electrodes filter elements.
Ein weiteres bevorzugtes Ausführungsbeispiel der Filtereinrichtung ist dadurch gekennzeichnet, dass die Kathode und/oder die Anode zusammen mit den Filterelementen in das Hüllrohr hinein und aus dem Hüllrohr heraus bewegbar sind/ist. Dadurch wird die Handhabung der erfindungsgemäßen Filtereinrichtung erheblich vereinfacht. Die Bewegungsrichtung ist vorzugsweise parallel zur Längsachse des Hüllrohrs.One Another preferred embodiment the filter device is characterized in that the cathode and / or the anode together with the filter elements into the cladding tube and from the cladding tube are movable out / is. As a result, the handling of the filter device according to the invention considerably simplified. The direction of movement is preferably parallel to the longitudinal axis of the cladding tube.
Die Filterelemente können als unbeschichtbare Filterelemente ausgebildet sein. Die Filtereinrichtung dient zum Filtern von Medien dient, die spannungsbedingt abgeschieden werden können.The Filter elements can be formed as an uncoatable filter elements. The filter device is used for filtering media that is deposited by voltage can be.
Die Filtereinrichtung ist insbesondere mit einer Beschichtung versehen, die ihrerseits unbeschichtbar ist. Dadurch bleiben die Partikel lediglich bei anliegender elektrischer Spannung an den Anoden/Kathoden haften. Bei Abschalten der angelegten elektrischen Spannung lösen sich die Partikel von den Ioden. Dieses Filterverfahren kann zum Filtrieren verschiedenster Medien bzw. Bäder eingesetzt werden. Ein Hauptvorteil besteht darin, dass nun keine Filtertücher zum Filtern benötigt werden, die sich leicht zusetzen können und anschließend aufwendig mittels Spülungen gereinigt werden müssen.The Filter device is provided in particular with a coating, which is itself uncoatable. This leaves the particles only with voltage applied to the anodes / cathodes be liable. When switching off the applied voltage dissolve the particles from the iodine. This filtering method can be used to filter a variety of Media or baths be used. A main advantage is that now no filter cloths for Filtering needed be that can easily enforce and then consuming by rinses need to be cleaned.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung verschiedene Ausführungsbeispiele im Einzelnen beschrieben sind.Further Advantages, features and details of the invention will become apparent the following description, with reference to the drawing various embodiments are described in detail.
Dabei zeigen:there demonstrate:
Bei der Lackierung von Kraftfahrzeugen beziehungsweise Teilen von Kraftfahrzeugen in der industriellen Großserienfertigung fällt viel Lackabwasser an, das aufwendig aufbereitet werden muss, um die darin enthaltenen Lackpartikel zu entfernen. Durch die vorliegende Erfindung wird eine Filtereinrichtung, insbesondere eine kathodische Filterpresse, geschaffen, die Filterelemente, insbesondere Filterplatten, umfasst, die Lackpartikel anziehen. Wenn die Filtereinrichtung gefüllt ist, dann werden die vorzugsweise unbeschichtbar ausgeführten Filterelemente trockengeblasen. Danach können die vorzugsweise in Plattenform vorliegenden Lackpartikel einfach abgefahren werden. Die Lackpartikel werden durch Kathoden/Anoden angezogen, die in die Filtereinrichtung, insbesondere die Filterpresse, integriert sind. Dadurch kann die Abwasserreinigung der Prozessabwässer der Lackierung deutlich vereinfacht werden.at the painting of motor vehicles or parts of motor vehicles in industrial mass production falls a lot Lackabwasser, which must be prepared consuming, in order remove paint particles contained. By the present invention is a filter device, in particular a cathodic filter press, which comprises filter elements, in particular filter plates, tighten the paint particles. When the filter device is filled, then the preferably uncoatable running filter elements blown dry. After that you can the paint particles are preferably in plate form easy be driven off. The paint particles are through cathodes / anodes attracted into the filter device, in particular the filter press, are integrated. As a result, the wastewater treatment of the process wastewater of Painting can be significantly simplified.
