Device for atomizing a liquid

Claim 1

A device for atomizing a liquid, said device being mounted on a frame, said device being in communication through first communication means with a pressurized gaseous fluid source, said device being in communication through second communication means with a pressurized liquid fluid source, said device comprising: a grommet attached to said frame, said grommet having a passage therethrough with one end of said passage in fluid communication with said first communication means, said passage having first and second opposite sides; a wing with a substantially symmetrical profile, said wing including means for injecting across a portion of said profile liquid fluid from said second communication means; means, attached to said wing, for dividing flow of said fluids along said wing profile, said dividing means extending from said wing to near said opposite sides of said passage in said grommet; and means for attaching said wing within said passage of said grommet; whereby said gaseous fluid flows through said passage in said grommet and across said wing, said liquid fluid mixing with said gaseous fluid where said injecting means introduces said liquid fluid to the flow of said gaseous fluid, said dividing means separating the flow of said fluids with respect to said wing to better mix said gaseous and liquid fluids to minimize the likelihood of ejection of a stream of liquid fluid from said passage in said grommet.

Claim 2

Claim 5

A device for atomizing a liquid, said device being mounted on a frame, said device being in communication through first communication means with a pressurized gaseous fluid source, said device being in communication through second communication means with a pressurized liquid fluid source, said device comprising: a grommet attached to said frame, said grommet having a passage therethrough with one end of said passage in fluid communication with said first communication means; a wing including means for injecting said liquid fluid into said gaseous fluid flowing across said wing, said wing further including means for dividing the flow of said fluids with respect to flowing along said wing, said passage in said grommet in regions above and below said wing having flat, substantially parallel sides, said dividing means extending at least one half the distance from said wing to each of said sides; means for attaching said wing within said passage to said grommet; and means for directing said liquid fluid from said second commuications means to said injecting means.

Claim 6

A device for atomizing a liquid, said device being mounted on a boom supported on a frame of an agricultural implement, said device being in fluid communication through first communication means with an air blower, said device also being in communication through second communication means with a tank having liquid therein, said second communication means including a pump, said device comprising: a grommet attached to said boom, said grommet having a passage therethrough with one end of said passage being in fluid communication with said first communication means; an air foil in the shape of a wing, said foil having a first upper surface and a first lower surface, said foil also having first leading and first trailing edges, said foil further having an opening extending therethrough from said first lower surface to said first upper surface, said opening having a side forming a second leading edge for a second wing, said second wing having a second upper surface and a second lower surface, said second wing extending from said second leading edge to meet and conform to the first upper and lower surfaces of said first wing; said passage in said grommet having first opposite sides with regions opposite said foil having flat surfaces which are substantially parallel with one another, said passage also having second opposite sides flaring away from one another to form an ever-expanding nozzle; means for attaching said foil within said passage to said grommet; means for directing said liquid from said second communication means into said opening in said foil to mix with the air and flow along said foil; and means for dividing said air and liquid mixture flowing along said foil, said dividing means extending from one of said first and second upper surfaces of said foil to near one of said flat first surfaces of said passage, said dividing means also extending from one of said first and second lower surfaces of said foil to near the other of said flat first surfaces of said passage.

Claim 7

A device for atomizing a liquid, said device being mounted on a boom supported on a frame of an agricultural implement, said device being in fluid communication through first communication means with an air blower, said device also being in communication through second communication means with a tank having liquid therein, said second communication means including a pump, said device comprising: a grommet attached to said boom, said grommet having a passage therethrough with one end of said passage being in fluid communication with said first communication means; an air foil in the shape of a wing, said foil having a first upper surface and a first lower surface, said foil also having first leading and first trailing edges, said foil further having an opening extending therethrough from said first lower surface to said first upper surface, said opening having a side forming a second leading edge for a second wing, said second wing having a second upper surface and a second lower surface, said second wing extending from said second leading edge to meet and conform to the first upper and lower surfaces of said first wing; said passage in said grommet having first opposite sides with regions opposite said foil having flat surfaces which are substantially parallel with one another, said passage also having second opposite sides flaring away from one another to form an ever-expanding nozzle; means for attaching said foil within said passage to said grommet; means for directing said liquid from said second communication means into said opening in said foil to mix with the air and flow along said foil; and means for dividing said air and liquid mixture flowing along said foil, said dividing means extending from one of said first and second upper surfaces of said foil to near one of said flat first surfaces of said passage, said dividing means also extending from one of said first and second lower surfaces of said foil to near the other of said flat first surfaces of said passage.
