Definitions

  • Patent No. 1,100,602 the stream of combustible gas, which feeds the flame and discharges between inner andintermediate nozzles, as wellas the atomizing gas stream, which discharges between intermedia'teand outer'nozzles, and also the material to be sprayed which is broken up into particles by the atomizing gas stream and melted by the flame of combustible gas, discharge from the'nozzle system in line with the axis of the nozzles, in a form of a cone With its apex at the outer nozzle.
  • the object of the present invention is to remedy the abovemdifiiculty, and this is effected by imparting to the flame of combustible gas, and to the spray particles carried forward .by the main stream of the atomizing gas, a direction which is deflected with respect to the axis of the nozzles, by bringing branch streams of atomizing gas, which are taken aside duringthe streaming out of the atomizing gas through the nozzle system and which are then allowed to act on the main stream of atomizing vgas and also on the mixture of combustible gas which feeds the flames, at an angle to thedirection at which the main stream emerges at the mouth of the nozzle.
  • FIG. 1 is a sectional elevation of a form portion of the ,inner nozzle 21, a middle nozzle 22 surrounding the inner nozzle 21 and consisting preferably, of two parts screwed into one another and an outer nozzle 23 surrounding the middle nozzle 22 and also consisting preferably of two parts screwed into one another.
  • a mixture consisting of combustible gas and oxygen under pressure or compressed'air is conveyed to the annular space between the nozzles 21 and 22, while compressed air or some other atomizing gas is conveyed to the annular space between the nozzles 22 and 23.
  • centrifugal action nozzle that is, an arrangement in which the particles of the material 5 to be-sprayed, besides being projected forwards, are also whirled round in a circle.
  • hollow objects such as tubes of small diameter, into which a nozzle of this kind is inserted, may be sprayed internally,
  • the inner nozzle 21 is attached to a long tubular part l 2 1 and the-nozzle 22 to a long tubular part 22 to suit the length of the articles to be coated, which long tubular parts are attached to a nozzle head (not shown inthe present case).
  • the outer nozzle consists of the tubu lar part 23 also attached to the nozzle head, i
  • a supporting sleeve 23 fixed b means of the Qnnular nut 11 to the end of t e part 23 and the mouth piece proper 233 of the outer 'nozzle, which is cut off obliquely at-the front.
  • This mouth piece 23 of the outer'nozzle is mounted on a sleeve-shaped supporting member 12, which is provided on one side with ball bearing races 13, 13.
  • the race-13" is fixed on the sleeve 23, which is provided at the front with an abutment 23, and is thus integral with the sleeve 23, while the ball race 13 lies against the supporting ring 12,
  • This rotation is caused to takeplace automatically by a portion of theatomizing air, which flows between the tubular parts 22, 23, having to pass a ring 15 of guide blades 15
  • This ring of guide blades is shown in Figs. 3 and 4 in side elevation and front elevation andconsists of an annular sleeve, in the periphery of which there are inclined or helical slits 15.
  • the compressed air which in passing through the slits l5 has a twist imparted to it, after passing through the guide wheel impinges against the blades of a ring'of rotor blades 16 mounted in an annular bore in: the mouth piece 23 of the outer nozzle, so that the air, which escapes from holes 17 provided in the nozzle part 23", in impinging against the blades of the rotor, exerts a turning moiiient on the rotor and thereby on the nozzle'part 23 in consequence of which the part 23, together with the supporting sleeve 12, turns about the stationary nozzle parts.
  • Themain stream of atomizing air passes unhindered out of the grooves let into the nozzle part 22 into the central bore of the mouthpiece 23 of the outer nozzle part and there atomizes the material to be sprayed, as it is fused.
  • a protecting sleeve 19 may be provided on it, which is slidable on the tubular part 23 and may be fixed thereon by a nut 18 and which surrounds the rotating part 1223 thus preventing it scraping against the walls ofthe article to be coated.
  • a nozzlesystem for atomizing wire-shaped material which has been fused from the solid to a fluid state, by means of a gaseous medium under pressure, comprising in combination an inner, an intermediate and an.
