ABSTRACT:
A cleaning apparatus for removing oily waste from articles which includes two tanks located in proximity, preferably in side-by-side relationship, to one another. The upper edge of one end of these tanks is provided with an overflow that causes the light surface fraction of the liquid in the cleaning tank to flow out of the cleaning tank and onto the surface of the liquid in the separating tank. The bottom edge of the opposite end of the separating tank is provided with an outlet through which the dense bottom fraction of the liquid in the separating tank may be withdrawn and pumped back into the cleaning tank. The effect of this top/bottom relationship between outlets and inlets is to establish a density gradient which favors the migration of oily waste from the cleaning tank to the separating tank.
Additionally, flow of fluid from the cleaning tank is directed into the separating tank so that a unidirectional flow pattern is established in the separating tank, while a circulatory flow pattern is established in the cleaning tank.
Another feature is the inclusion within the separating tank of a waste separating assembly which includes an array of parallelly disposed rigid plates composed of an oleophilic material such as polypropylene, and which include large numbers of relatively small openings. The assembly promotes and hastens the coalescence of oily waste into globules large enough to rise rapidly to the surface of the liquid in the separating tank where they can be easily removed.
