Abstract
Apparatus for cleaning fluids, especially cooling lubricants of machine tools. The apparatus includes a tank having a partition subdividing it into a sedimentation chamber and a clean chamber and having an inlet for the contaminated cooling lubricant and a discharge device for the cleaned cooling lubricant. A filter is mounted between the sedimentation chamber and the clean chamber and a conveyor device is mounted in the sedimentation chamber for removing sedimented particles from the tank. An environmentally safe and low-maintenance cleaning apparatus according to this invention is created by the fact that the sedimentation chamber is subdivided by a partition into an inlet area and a preliminary cleaning area that are connected to each other by a passage in the lower area of the partition. The filter is an edge filter mounted in the partition between the preliminary cleaning area and the clean chamber.
