  • Collection container with transport pump
    Patent number: 5932094
    Abstract: A collection container with transport pump (4) for conveying liquids containing production residues, for instance chips, coolant and lubricant. The collection container (1) is developed as a cylindrical pot with a substantially flat container floor (5). A rake which travels over the container floor (5) conducts the chips which have deposited on the container floor to the transport pump (4). The collection container thus has a slight structural height and assures optimal removal of the chips by means of the transport pump.
