Abstract
A filter system for removing and/or neutralizing undissolved oils, greases, and salts on/in water-containing emulsions from, in particular, tanks and baths that are used to hold and store emulsions, which are used to cool and lubricate workpieces and tools during machining, comprising at least one emulsifier filter, a downstream suction/pressure pump, a unit for gas enrichment, an adhesion filter having an automatic deaerator, a downstream oil-collecting vessel, and a capillary filter, wherein these are combined as a unit, such that the oil/grease film and the emulsion can be mechanically, chemically, and biologically treated.
Claims26
A filter system for removing and/or neutralizing undissolved oils, greases and salts in/on aqueous emulsions from tanks and baths in particular, which are used for holding and storing emulsions, which are in turn used for cooling and lubricating workpieces and tools during machining, the filter system comprising:
- one device as a tangential feed into an emulsifier filter;
- an injector for gas enrichment;
- an adhesion filter having an automatic ventilator;
- and
- an oil collecting vessel having a drain,
- wherein the filter system is operative to treat the emulsion containing insoluble oil/grease droplets mechanically, physically and biologically, such that an oil/grease layer is then discharged from the filter system.

A method for removing and/or neutralizing undissolved oils, greases and salts in/on aqueous emulsions from tanks and baths in particular, which are used for holding and storing emulsions, which are in turn used for cooling and lubricating workpieces and tools during machining, the method comprising:
- removing an oil/grease film and parts of the emulsion from a tank or a bath using a skimmer;
- and
- filtering the oil/grease film and parts of the emulsion through at least one element including a plurality of plastic plates, the plurality of plastic plates arranged side by side and combined to form a body, the plastic plates constructed of a plastic having a water uptake capacity of more than 1%.
A method for removing metal abrasion debris from aqueous emulsions from tanks and baths in particular, which are used for holding and storing emulsions, which are in turn used for cooling and lubricating workpieces and tools during machining, the method comprising:
- removing an oil/grease film and parts of the emulsion from a tank or a bath using a skimmer;
- and
- filtering the oil/grease film and parts of the emulsion through at least one element including a plurality of plastic plates, the plurality of plastic plates arranged side by side and combined to form a body, the plastic plates constructed of a plastic having a water uptake capacity of more than 1%.
