Abstract
A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.
Claims13
A fluid injection system comprising:
- a. a container having a sidewall, bottom wall and open top perimeter defining a cavity;
- b. a fluid injection device removably coupled about the top perimeter of container, the fluid injection device comprising:
- i) a housing adapted to mount onto the container, wherein the housing includes a flow tube defining a fluid pathway, the flow tube having:
- a) an inlet end configured to receive a feeder fluid;
- b) an outlet end configured to discharge a mixed fluid comprising the product and feeder fluid;
- c) a shroud positioned an intermediate distance between the inlet end and the outlet end, wherein the shroud has a first end and a second end defining a ramped surface therebetween whereby the shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway;
- d) a diverter port between the inlet end and the shroud, wherein the diverter port is configured to divert a portion of the feeder fluid from the inlet end into the container;
- e) an injection port between the shroud and the outlet end;
- and
- ii) an injection tube having a first end coupled to the injection port and an opposing second end extending into the cavity and terminating an intermediate distance above the bottom wall of the container;
- and
- c. a fertigation basket configured to hold a dry product including:
- i) a top collar configured to mount to the open top perimeter of the container between the container and the fluid injection device housing whereby the diverted portion of the feeder fluid is directed into the fertigation basket to dissolve the dry product;
- ii) inner and outer basket sidewalls coaxially aligned along the longitudinal axis of the basket and extending into the cavity of the container, wherein the inner basket sidewall has an internal diameter defining a channel larger than the outer diameter of the injection tube, and wherein the outer basket sidewall has an external diameter smaller than an internal diameter of the container sidewall;
- and
- iii) a basket bottom extending between bottom edges of the inner and outer basket sidewalls, wherein the injection tube is configured to pass through the channel with the second end of the injection tube extending outwardly of the basket bottom,
- wherein one or both of the outer basket sidewall and basket bottom define a plurality of openings whereby dissolved product passes out of the fertigation basket and into the container, and
- wherein the injection tube is configured to transport the dissolved product from the container to the outlet end of the flow tube.
