Abstract
A liquid storage tank for storing a dual temperature liquid comprising an enclosed tank which is circular in horizontal section; a vertical radial stationary partition in the tank; a vertical radial partition in the tank rotatably movable about the vertical axis of the tank; a seal preventing liquid flow between opposite sides of the movable partition and opposite sides of the stationary partition; an opening for feeding a liquid to a first side of the stationay partition and withdrawing liquid therefrom; and an opening for feeding a liquid to a second side of the stationary partition and withdrawing liquid therefrom.
Claims15
A liquid storage tank for storing two separate volumes of liquid at different temperatures, comprising:
- an enclosed roofed tank which is circular in horizontal section about a vertical axis;
- a vertical radial stationary partition in the tank;
- a vertical radial partition in the tank having a top edge out of sealing contact with the roof and means mounting the partition to be rotatably movable about the vertical axis of the tank by a difference in hydrostatic force on each side of said partition;
- means preventing liquid flow between opposite sides of the movable partition and opposite sides of the stationary partition;
- means for feeding a liquid to a first side of the stationary partition and withdrawing liquid therefrom;
- and
- means for feeding a liquid to a second side of the stationary partition and withdrawing liquid therefrom.
A liquid storage tank for storing two separate volumes of liquid at different temperatures, comprising:
- an enclosed tank having a circular flat bottom, a vertical circular cylindrical wall having a lower end joined to the bottom and an upper end joined to and supporting a roof;
- a vertical radial stationary partition in the tank having a height about equal to the tank wall height, extending from about the tank center and joined to the tank bottom and wall;
- a vertical radial movable partition in the tank having a height about equal to the tank wall height and terminating at the top out of sealing engagement with the roof and extending from about the tank center to the tank wall, and support means mounting the movable partition so that it can rotate about the vertical axis of the tank by a difference in hydrostatic force on each side of the partition;
- means preventing liquid flow between opposite sides of the movable partition and opposite sides of the stationary partition;
- means for feeding a liquid to a first side of the stationary partition and withdrawing liquid therefrom;
- and
- means for feeding a liquid to a second side of the stationary partition and withdrawing liquid therefrom.

- a vertical column axially positioned in the tank to which the stationary partition is joined;
- means for connecting the movable partition to the vertical column, for permitting rotation of the movable partition relative to the vertical column;
- means preventing liquid flow between opposite sides of the movable partition and opposite sides of the stationary partition;
- means for feeding a liquid to the first side of the stationary partition and withdrawing liquid therefrom;
- and
- means for feeding a liquid to a second side of the stationary partition and withdrawing liquid therefrom.
