ABSTRACT:
Magnetic filter apparatus with a plurality of magnetic bars, carried on endless conveyor chains through a container for contaminated liquid, having for the cleaning of said magnetic bars a device which is positioned outside the liquid above the fluid container. The cleaning device has at least two chain-driven dirt scrapers with wiping formations which enclose from above and below one or more magnetic bars during the cleaning process. In order that the dirt removed during the scraping operation should not fall onto the driving chains, the chain drive is positioned above and to the side of the liquid container. The chain drive moves a steered carriage which bears scraping rods which can be opened and closed pincer-fashion. The dirt scrapers are positioned on the front ends of these rods which project over the container area. The cleaning process takes place with pincers closed, the return stroke with pincers open.
