Abstract:
Apparatus to be used for maintaining the condition of cutting fluids in a machine tool sump and the removal of undesirable constituents therefrom, the apparatus comprising:an auxiliary tank located to receive and contain fluids circulated by the fluid pump at a predetermined level;a fluid pump connected to pump fluids from the machine tool sump to the auxiliary tank;a turbine wheel mounted in the auxiliary tank and having a horizontal axis of rotation, with the fluid flow from the pump being directed to rotate the turbine wheel and thereby also aerate the fluid;a fluid conductor connected to the auxiliary tank to drain excess fluid from the auxiliary tank to the machine tool sump;a substantially horizontal shaft mounted for rotation in the tank and driven by the turbine wheel;at least one drum mounted for rotation on the substantially horizontal shaft and being connected to the turbine wheel to be rotated thereby, with a portion of the drum surface rotating below the given fluid level and wetted by the undesirable constituents;a wiper contacting the drum surface of the at least one rotating drum along a line above the given fluid level so as to strip undesirable constituents from the drum surface; anda collector below the wiper contact line to receive the undesirable constituents from the drum surface.
