Oil separator for separating oil lighter than the purified liquid being in a very pure state

A device for separating oil from an oil laden liquid comprising:

• a. a tank having oil laden liquid, side walls and a bottom with an inlet in a first side wall below the surface of said oil laden liquid for introducing the oil laden liquid and an outlet in a second side wall for the purified liquid;
• b. means for separating oil from an oil laden liquid comprising at least two parallel inclined plates spaced from each other in the tank;
• c. one of the parallel plates extending at an incline from and having one edge fixed to the first side wall to define a space with said first side wall adjacent the inlet to minimize the turbulence of the incoming liquid;
• d. the other parallel plate extending from and having one edge fixed to the second side wall to define a second space adjacent the outlet;
• e. each plate having a free edge opposite its fixed edge, one free edge pointed upwardly and the other free edge pointed downwardly;
• f. oil discharge means near the top of the tank for removal of the separated oil whereby oil laden liquid entering into said tank through the inlet has the turbulence thereof almost completely eliminated before entry into one end of said separating means wherein the oil is separated from the oil laden liquid so that the separated oil gathers near the top of the tank and is discharged therefrom through said discharge means and the purified liquid then flows from the other end of the separating means and is discharged through the outlet.
