Abstract

Apparatus for returning cooling lubricant, which adheres to the swarf when machining metals, consisting of the combination of a swarf conveyor 2 for discharging the swarf with a vacuum filter unit 3 located therebelow for cleaning the cooling lubricant contaminated with the fine swarf. The swarf conveyor 2 as well as the vacuum filter unit 3 consists of horizontal flat box sections 2a,3a, which can be pushed below a machine tool 4, as well as of inclined flat box sections 2b or 3b for receiving the drives 31 or 15 for a hinge belt 5 of the swarf conveyor 2 or a scraper belt 16 of the vacuum filter unit 3 and for receiving a filter band storage roll 21, from which the scraper belt 16 withdraws a filter band 14. Since the liquid accumulating in the flat box section 2a and which is still contaminated, is able to flow over lateral openings 6 and lateral inlet boxes 7 of the vacuum filter unit 3 into its contaminated chamber 8, the overall height of the flat box sections 2a and 3a can be kept so low that these horizontal parts of the apparatus are located below the machine tools. The clean liquid collecting in a chamber 13 below a perforated plate 12 is sucked-off for re-use by a pump 2…
