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.

A transportable chemical mixing system, comprising: a trailer having a pair of wheels for moving the trailer over ground, a hitch at a forward end for connecting the trailer to a prime mover, and a frame; a drum for storing diluent fluid, removably mounted on said trailer frame; a mixing tank for mixing chemicals with diluent fluid from the drum, mounted on the trailer frame; said mixing tank having a lower cone-shaped funnel portion with an outlet centered in a lower end and an upper portion with a removable lid on an upper end; liquid within said tank forming a vortex with a vertical axis passing through the outlet as the liquid is dispensed from the outlet; an ejector disposed within said tank upper portion, for ejecting a liquid into the tank and mixing the ejected liquid with the liquid within the tank, said ejector including: a pair of spaced apart outlet nozzles for dispensing fluid from the ejector; said nozzles having axes along which liquid is sprayed and which are generally parallel to one another and spaced equally apart on diametric sides of the vortex axis; said nozzle spray axes oriented downwardly at an angle from horizontal to direct liquid sprayed from the nozzles into the liquid in the tank forming the vortex, to thereby disrupt the vortex; an hydraulic circuit fluidly connecting the tank outlet and the ejector, to circulate fluid from the tank through the ejector and back to the tank; a pump interposed in said hydraulic circuit for moving liquid within the circuit in a direction from the tank outlet to the ejector; a conduit extending from the drum and connected to the hydraulic circuit upstream of said pump to provide diluent fluid from the drum to the circuit; a hose having an inlet end connected to said hydraulic circuit downstream of said pump to direct fluid from the circuit to a distal end of the hose; and means on the distal end of the hose for connecting the hose to fluid dispensing apparatus.
