Definitions
- EUGNE oDAM or PARIS, FRANCE PROCESS AND APPARATUS FOR ATOMIZING MATERIALS IN A MELTED STATE.
- This invention relates to a process for atomizing materials su-ch as metals, chemical products, vitreous materials, etc.; while in a melted condition, according to which the said materials are first heated by the flame and gases produced by the combustion under pressure of a suitable solid, liquid or gaseous pansion of the' said gases in open air.
- Figure l is a sectional view of one em. bodiment of the apparatus of the present invention and in which the process may be carried out, and
- Figs. 2, 3 and 4 are viewsv of the preferred embodiment, Fig. 2 being a vertical sectional View (with parts'in elevation), Fig. 3 arear elevation of the parts at the upper left-hand side of Fig. 2, and Fig.A 4 a cross-sectional view of Fig. 3. v
- the apparatus consists of a chamber c formed by a metal wall b covered internally with a refractory lining c.
- the said chamber is provided with a gas burner l supplied by pipes e with combustible gas under pressure and by pipes f, g, with compressed air, the latter extending from a single pipe 71. to which is also connected a supplementary air pipe z' opening into the chamber a above the burner d.
- a gas burner l supplied by pipes e with combustible gas under pressure and by pipes f, g, with compressed air, the latter extending from a single pipe 71. to which is also connected a supplementary air pipe z' opening into the chamber a above the burner d.
- These various pipes are provided with cocks c1, f1, g1, 1, which allow of suitably regulating the proportion of combustible gas and compressed air.
- the chamber a is traversed by a pipe In through which flows the molten material coming lfrom a hopper Z, The material is poured into the hopper Z in molten condition, from any suitable crucible or furnace in which it has been melted, or is ladled from such a furnace into said hopper Z.
- This pipe terminates in a nozzle m .located in the middle of an outlet nozzle fn,
- Plugs o and p are provided t0 afford access to the chamber a for lighting and cleaning purposes, etc.
- the chamber a is divided into two compartments a1, a? communicating with each other, one containing the furnace Z constituting the combustion chamber proper, and the other, traversed by the feed pipe c,-ancl provided with theoutlet nozzle n, ⁇ forming the chamber for heating fthe matefials under treatment and for the discharge of the gases, so as to allow of arranging the apparatus to suit particular cases and to facilitate the erection and dis- -mounting thereof.
- the operation of the apparatus is as follows
- the burner d having been lighted and the combustlon propprly regulated by operating the various coc s e1, f1, g1, il the molten material is fed through the pipe le.
- Dur-ing lts passage through the said pipe it is heated by the flame and gases at a high temperature produced by the action of the burner.
- As it issues from the nozzle m it is atomized by the sudden expansion in the 'open air of the' gases of combustion escaping around the said nozzle through the outlet aperture of the nozzle n.
- the preliminary heating of the molten i materials is Very important as it -prevents them fromA solidifying, as ,they might toward the outlet of the nozzle m owing to the lowering of the temperature caused by the expansion of the gases.
- An apparatus of the character 'described comprising. a conduit for melted material, 'and an exit nozzle for combustion gases under pressure, said nozzle surround. mg the extremity of said conduit, the in- ⁇ terior Walls of said nozzle being cylindrical and concentric to the exterior surface of said lconduit, in such manner that the gas escapes parallelly to the flow of the fused material, whereby toA entrain it at the same time that the gases produce the division and pulverization of said material by their eX- pansion into the free air.
- An'apparatus according to claim 2 further comprising a combustion chamber, and said combustion chamber having an eXit Which forms the gas exit nozzle.
