<p>A liquid mixing device for mixing liquids in a mixing tank. The device providing means for mixing liquids such as liquid chemicals that are generally difficult to mix and mixing these chemicals together to form a homogeneous solution. The device is adapted for skimming an unmixed liquid on top of the liquid level with a heavier liquid at the bottom of the mixing tank. Also the device will mix an unmixed liquid at various levels in the mixing tank with a heavier liquid at the bottom of the tank. In the tank is a vertical inner tube with a spiral slot, enclosed in an outer tube with a vertical slot. By indexing these slots an elongate aperture into the tubes can be adjusted to any selected depth in the tank to receive liquid from that depth and mix it with liquid received through the top or bottom of the tubes.</p> |
