1. A device for collecting used sealing fluids/grease being used as sealing and lubricating medium between two objects characterized in that the device comprises a container/tank (I) including two or more separation units (II,III) for separating introduced sealing fluid/grease from oil and water in a mixture of said components, said separation units (II,III) standing in fluid communication with each other, and wherein
said first separation unit (II) comprises a number of separating drawers (4,5,6) and that all have an inside, said inside comprising devices (4) for removing gas/air from the sealing fluid/oil/water mixture, and a plurality of retention devices (5,6) for separating solid matter/solid particles from said mixture, as well as retention devices (8) for magnetic materials in said mixture, and a second separation unit comprising a flotation tank (III) with internally perforated separation walls (13) and at least one flotation device (14) for separating sealing fluid/grease from water in said mixture, said separation being based on separating the components of the mixture through using differences in the densities of the components of the sealing fluid/oil/water mixture, as well as an exit (15) for the separated sealing fluid/grease and another exit (12) for the mixture of remaining oil and water, wherein the exit (15) for the separated sealing fluid/grease is connected to a pump or similar device configured to reintroduce the separated sealing fluid/grease into the space between the two objects. |
