Abstract
An atomizing method for atomizing a fluid atomizing material feeds fluid atomizing material into jet air. A pair of planar air jets flow through nozzle tips towards a center axis of an atomization material supply. This forms an air chamber which converges in front of the atomization material supply. The interior edge of the converged air jets has a zone of slow moving air that draws the fluid atomizing material into the converging air jets. The material is thus atomized and evenly distributed. The atomization material supplied includes such fluidized atomizing materials as molten metal droplets fused by arc heat, paints, blast materials, adhesives, powders, etc.
Claims8
An arc fusing method comprising:
- forming a pair of plane air jets, each said plane air jet having a thickness center line and a width center line;
- jetting said pair of plane air jets from a pair of nozzle tips toward a convergent portion on a fusing center axis, said thickness center line converging on said fusing center axis in front of an arc intersecting point, said fusing center axis being interposed between said pair of nozzle tips;
- jetting air in a first of said pair of plain air jets along said width center line in an incline with respect to said fusing center axis while jetting air in a second of said pair of plain air jets along said width center line in an opposite incline with respect to said fusing center axis;
- forming an air chamber bounded by converging of said thickness center lines of said pair of plane air jets on said fusing center axis;
- and
- generating an arc discharge continuously between a pair of fusible materials at said arc discharge point in a low velocity air flow zone toward a convergent portion within said air chamber.
An arc fusing device comprising:
- first and second nozzle tips for forming first and second plane air jets respectively;
- each said first and second plane air jet having a thickness center line and a width center line;
- said first and second nozzle tips being directed inwardly to converge said thickness center lines toward a fusing center axis thus forming a convergent portion;
- said first nozzle tip being positioned in a first offset position and said first nozzle tip being directed whereby said width center line of said first plane air jet is inclined with respect to said fusing center axis;
- said second nozzle tip being positioned in a second offset position and said second nozzle tip being directed whereby said width center line of said second plane air jet is inclined with respect to said fusing center axis and oppositely inclined with respect to said width center line of said first plane air jet;
- and
- an arc intersecting point of a pair of fusible materials being positioned in a low velocity air flow zone toward a convergent portion within an air chamber defined by said pair of plane air jets and in a rear position in a longitudinal direction of said convergent portion.
