  • Patent number: 5609417
    Abstract: An apparatus for mixing chemicals and fluids includes a mixing tank with a cone-shaped funnel portion and an outlet in the lower end thereof. An ejector with a pair of spray nozzles sprays the mixture of liquid and chemicals drained from the tank outlet back into the tank. The nozzles are oriented with their axes parallel to one another and angled downwardly towards the surface of the liquid within the tank and on opposing sides of a line extending vertically from the center of the tank outlet. An hydraulic circuit is formed to circulate fluid drained from the tank back to the ejector, and a pump is provided to move the liquid within the circuit. A hose is connected in the circuit, with an operable valve to selectively exhaust the mixed chemical and diluent from the circuit to a spraying apparatus.
