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.
Claims32
A liquid transfer system comprising:
- a liquid supply tank;
- at least two pressurizable liquid holding vessels;
- a liquid supply line being connected between said tank and each said vessel for supplying liquid from said tank to each said vessel;
- said liquid supply line being engaged to said tank to act as a liquid siphon in withdrawing said liquid from said tank and supplying said liquid to said vessel;
- a siphoned liquid sensor means being operatively engaged within said liquid supply system to provide an indication that siphoned liquid is passing from said liquid supply tank to said liquid holding vessels;
- and
- a liquid output line being operatively engaged to said liquid holding vessels for the transfer of liquid therefrom.
A liquid transfer system comprising:
- a liquid supply tank;
- at least two pressurizable liquid holding vessels;
- a liquid supply line being connected between said tank and each said vessel for supplying liquid from said tank to each said vessel, said liquid supply line being engaged to said tank to act as a liquid siphon in withdrawing said liquid from said tank and supplying said liquid to said vessels;
- a vacuum means being operatively engaged to said liquid supply line to initiate said liquid siphon within said liquid supply line;
- a siphoned liquid sensor means being operatively engaged within said liquid supply system to provide an indication that siphoned liquid is passing from said liquid supply tank to said liquid holding vessels;
- and
- a programmable electronic control unit being engaged to said siphoned liquid sensor means and to said vacuum means and operating to turn off said vacuum means when said passing of siphoned liquid is indicated.
A liquid transfer system comprising:
- a liquid supply means;
- at least two pressurizable liquid holding vessels;
- a liquid supply line being connected between said liquid supply means and each said vessel for supplying liquid from said liquid supply means to each said vessel, said liquid supply line being engaged to said liquid supply means to act as a liquid siphon in withdrawing said liquid from said tank and supplying said liquid to said vessels;
- a gas pressure means being operatively engaged to said liquid supply means to initiate said liquid siphon within said liquid supply line;
- a liquid output line being operatively engaged to said liquid holding vessels for the transfer of liquid therefrom.
