Immiscible separating device

Claim 1

Apparatus for separating first and second immiscible liquids having different specific gravities including a reservoir means to hold said first and second liquids, said reservoir having a reservoir outlet means of selected diameter adjacent a lowest part of the reservoir for emission of mixtures of said first and second liquids, a first conduit having a first conduit inlet of first diameter connected to said reservoir outlet, and a first conduit outlet of second diameter greater than said first diameter, where a segment of said first conduit between said first conduit inlet and said first conduit outlet has a downward offset; vertically disposed elongate separator means having midsection means of selected diameter; midsection inlet means connected to communicate with said first conduit outlet, and midsection first and second openings; first receiver means located above said midsection means having a diameter greater than the diameter of said midsection, first receiver inlet means communicating with said first midsection opening; closure means over the end of said first receiver opposite said first receiver inlet; a second receiver located beneath said midsection means having a diameter greater than said midsection where said second receiver has an inlet means in communication with said second midsection opening and second receiver has a bottom outlet means; vertically movable sight gage means connected to the second receiver bottom outlet means by flexible conduit means, said sight gage having a gage outlet exposed to the atmosphere and a liquid outlet adjacent to said gage outlet exposed to the atmosphere.

Claim 6

A method of separating immiscible first and second liquids, said first immiscible liquid having a specific gravity greater than the specific gravity of said second immiscible liquid, where a reservoir is provided to hold the immiscible liquids and to allow the second liquid to settle to the bottom portion of the reservoir, including supplying a portion of the first and second liquids to a separatory device by a first conduit having a first conduit inlet of first diameter connected to said bottom portion of said reservoir and a first conduit outlet of second diameter greater than said first diameter, where a segment of said conduit between said first conduit inlet and said first conduit outlet has a downward offset; said separatory device having a midsection of selected diameter, and an inlet connected to said first conduit outlet and first and second midsection outlets where a first receiver having a diameter greater than said midsection is disposed above the midsection in communicative relation with the first midsection outlet and a second receiver is disposed beneath the midsection and in communicative relation with the second midsection outlet, where the second receiver has a diameter greater than the diameter than the midsection, and outlet means adjacent the bottom of the second receiver communicating with flexible outlet conduit means and vertically adjustable sight gage means having a gage outlet exposed to the atmosphere and a liquid outlet adjacent to said gage outlet exposed to the atmosphere; filling the second reservoir with said second immiscible fluid to a level within the midsection, adjusting the sight gage to a height above the level of the second liquid in the second receiver, admitting the first and second liquids from the reservoir to the midsection and the first receiver, adjusting the height of the sight gage to a level where said second immiscible liquid flows from the sight gage, and allowing said second immiscible liquid to flow from the sight gage as additional first and second immiscible liquids are received in said midsection.

Claim 7

A method of separating immiscible first and second liquids, said first immiscible liquid having a specific gravity greater than the specific gravity of said second immiscible liquid, where a reservoir is provided to hold the immiscible liquids and to allow the second liquid to settle to the bottom portion of the reservoir, including supplying a portion of the first and second liquids to a separatory device by a first conduit having a first conduit inlet of first diameter connected to said bottom portion of said reservoir and a first conduit outlet of second diameter greater than said first diameter, where a segment of said conduit between said first conduit inlet and said first conduit outlet has a downward offset; said separatory device having a midsection of selected diameter, and an inlet connected to said first conduit outlet and first and second midsection outlets where a first receiver having a diameter greater than said midsection is disposed above the midsection in communicative relation with the first midsection outlet and a second receiver is disposed beneath the midsection and in communicative relation with the second midsection outlet, where the second receiver has a diameter greater than the diameter than the midsection, and outlet means adjacent the bottom of the second receiver communicating with flexible outlet conduit means and vertically adjustable sight gage means having a gage outlet exposed to the atmosphere and a liquid outlet adjacent to said gage outlet exposed to the atmosphere; filling the second reservoir with said second immiscible fluid to a level within the midsection, adjusting the sight gage to a height above the level of the second liquid in the second receiver, admitting the first and second liquids from the reservoir to the midsection and the first receiver, adjusting the height of the sight gage to a level where said second immiscible liquid flows from the sight gage, and allowing said second immiscible liquid to flow from the sight gage as additional first and second immiscible liquids are received in said midsection.
