Device for filtering media e.g. lacquer/cathodic dipping lacquer, comprises membrane filter element, inlet to introduce unfiltered medium into the device, outlet to discharge filtered medium from the device, and filtrate collection chamber

摘要

The filter device (13) comprises a membrane filter element (11), which partially consists of an organic material and is equipped with an effective grounding path against Earth's mass, an inlet (6) for introducing the unfiltered medium into the filter device, an outlet (6b) for discharging the filtered medium from the filter device, and a filtrate collection chamber, which is designed for collecting the filtrate (6a) filtered off from the membrane filter element. The membrane filter element is disposed between the inlet and the outlet, so that it flows through the medium to be filtered. The filter device (13) comprises a membrane filter element (11), which partially consists of an organic material and is equipped with an effective grounding path against Earth's mass, an inlet (6) for introducing the unfiltered medium into the filter device, an outlet (6b) for discharging the filtered medium from the filter device, and a filtrate collection chamber, which is designed for collecting the filtrate (6a) filtered off from the membrane filter element. The membrane filter element is disposed between the inlet and the outlet, so that it flows through the medium to be filtered, and is equipped with a spacer and media flow channels, which are designed to flow through by the medium to be filtered. The grounding path comprises an electrically conducting media flow channel conductor, which is area-wisely positioned in the media flow channel. The media flow channel conductor completely or partially consists of conductible and/or dischargeable metallic, non-metallic or polymer material, comprises conductible and/or dischargeable metallic, non-metallic or polymer wires, metal fabric, metal gauze and/or coatings, and is formed as conductible and/or dischargeable metallic, non-metallic or polymer spacer. The membrane filter element is implemented as a winding module, where the media flow channel conductor is formed from a coating of the spacer consisting of conductive lacquer or conductive plastic. The grounding path comprises a conductor for electrical connection between the media flow channel conductor and earth. An independent claim is included for a method for filtering cathodic dipping lacquer with a filter device.
