Abstract
The liquid transfer system includes a liquid supply tank and at least two pressurizable liquid holding vessels. The liquid holding vessels are placed beneath the supply tank, and a liquid supply line connects the supply tank to each vessel. The liquid supply line is operated as a siphon from the tank to each vessel, in order to move liquid from the tank to each vessel. Each vessel is alternately filled and pressurized to dispense liquid from the vessel, such that one vessel is being filled while the other is dispensing liquid, and a constant controllable liquid output flow is achieved. A preferred embodiment includes a liquid recycling line to recycle or constantly move the liquid within the system to achieve thorough mixing, and an in-line filter to improve liquid purity.
Claims12
A method for transferring liquid from a liquid supply tank to a liquid output line, comprising the steps of:
- siphoning liquid from said liquid supply tank through a liquid supply line to a plurality of pressurizable liquid holding vessels, for filling said vessels;
- pressuring said liquid holding vessels to greater than atmospheric pressure to remove liquid from said vessels to a liquid output line.
A method for transferring liquid from a liquid supply tank to a liquid output line, comprising the steps of:
- applying a vacuum pressure to a liquid supply line to initiate the siphoning of liquid from said liquid supply tank to a plurality of pressurizable liquid holding vessels, for filling said vessels;
- detecting siphoned liquid flow within said liquid supply line;
- shutting off said vacuum following said detecting of siphoned liquid within said liquid supply line.
A method for transferring liquid from a liquid supply tank to a liquid output line, comprising the steps of:
- supplying pressurized gas to said liquid supply tank to initiate the siphoning of liquid from said liquid supply tank through a liquid supply line to a plurality of pressurizable liquid holding vessels, for filling said vessels;
- pressurizing said liquid holding vessels to remove liquid from said vessels to said liquid output line.
