Abstract

Abstract Apparatus for pumping oil-water mixture from the collection vessel of a floating oil collector into settling tanks comprises at least one oil receiving means for collecting oil-water mixture, arranged below the level of the liquid in the collection vessel and connected through a conduit to the upper part of one of the settling tanks. Besides, the apparatus includes means providing for vertical displacement of the oil receiving means and a pump for pumping water from the lower part of one of the settling tank outboard of the floating oil collector and an aspirating air-water jet ejector for maintaining substantially permanent vacuum in each settling tank. The ejector has the air line thereof connected to the upper part of each settling tank and the jet thereof connected to the delivery side of the pump. The lower part of one of the settling tanks is connected to the upper part of that settling tank from the lower part of which this pump draws water. The liquid column established in the conduit connecting the oil receiving means with the upper part of the said settling tank is higher than the liquid column established in said other conduit.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 218 words
An apparatus for pumping oil-water mixture from a collection vessel of a floating oil collector into settling tanks, comprising: closed settling tanks, at least one oil receiving means for collecting oil-water mixture, arranged below the level of the liquid in said collection vessel; means providing for vertical displacement of said oil receiving means; a pump for pumping water from the lower part of one of said settling tanks outboard of said floating oil collector; an aspirating air-water jet ejector for maintaining substantially permanent vacuum in each said settling tank, said ejector having the air line thereof connected to the upper part of each said settling tank, said ejector having the jet nozzle thereof connected to the delivery side of said pump; a conduit connecting said oil receiving means with the upper part of one of said settling tank; a second conduit connecting the lower part of said one settling tank having the upper part thereof connected by said first-mentioned conduit with said oil-receiving means, to the upper part of another said settling tank from said lower part of which said pump is connected to pump water, the water column established in said first-mentioned conduit connecting said oil-receiving means with said upper part of said one settling tank being higher than the water column established in said second conduit.
Claim 2
Independent Claim 218 words
An apparatus for pumping oil-water mixture from a collection vessel of a floating oil collector into settling tanks, comprising: closed settling tanks, at least one oil receiving means for collecting oil-water mixture, arranged below the level of the liquid in said collection vessel; means providing for vertical displacement of said oil receiving means; a pump for pumping water from the lower part of one of said settling tanks outboard of said floating oil collector; an aspirating air-water jet ejector for maintaining substantially permanent vacuum in each said settling tank, said ejector having the air line thereof connected to the upper part of each said settling tank, said ejector having the jet nozzle thereof connected to the delivery side of said pump; a conduit connecting said oil receiving means with the upper part of one of said settling tank; a second conduit connecting the lower part of said one settling tank having the upper part thereof connected by said first-mentioned conduit with said oil-receiving means, to the upper part of another said settling tank from said lower part of which said pump is connected to pump water, the water column established in said first-mentioned conduit connecting said oil-receiving means with said upper part of said one settling tank being higher than the water column established in said second conduit.
Claim 3
Dependent Claim 57 words
An apparatus as claimed in claim 1, wherein each said settling tank is associated in the upper part thereof with an additional vessel having such dimensions that the height of said additional vessel is substantially greater than the width thereof, while the volume of said additional vessel is substantially smaller than the volume of said settling tank.
