  • Device for receiving and separating chips created by machine tools and coolant (overflow)
    Patent number: 7014760
    Abstract: A device is disclosed for receiving and separating chips and coolant collecting on machine tools, the coolant being returned for reuse and the chips being removed, having a receiving tank (1) to receive the chips and the coolant, a rising guide section (3) adjoining the receiving tank (1), an elevated discharge section (4) adjoining the guide section (3), a chain-like closed transport element, which, at least in the region receiving the chips and the coolant and in the discharge section (4), is guided over deflection elements (6, 7), at least one of which is coupled to a rotary drive, and a rotatably mounted filter drum (12), which is in drive connection with the transport element. A suggestion is made for preventing unfiltered coolant from penetrating the tanks for filtered coolant in the event the receiving tank overflows.
