Chip discharge for continuous chip wringer

摘要

A centrifuge for continuously separating a lubricating liquid from lubrication-impregnated metal chips. A motor having a drive shaft thereon is mounted so that the drive shaft is drivingly coupled to a substantially bell-shaped centrifugal drum having an outwardly widening conical portion. The drum is formed with openings intermediate the top edge and bottom wall for discharge of the liquid therethrough. A metal chip and air inlet is provided adjacent the central portion of the outwardly opening drum. A first collecting structure is provided for collecting the liquid emanating from the lubrication-impregnated chips and for discharging the liquid from the centrifuge. A second annular collecting structure surrounds the peripheral edge of the drum radially outwardly spaced therefrom for collecting shavings discharged by centrifugal action from the drum. An outlet duct is connected to the second collecting structure and has a central axis extending tangential to the second collecting structure and away therefrom and defining a metal chip and air outlet. A plurality of blades may be mounted on the drum adjacent the top edge and are movable therewith for effecting a movement of air into the second annular collecting structure from the air inlet and out through the outlet duct to effect an entrainment of the metal chips in the air movement for discharge out through the outlet duct.
