Definitions

  • the present invention relates to a device for separating a long product in movement from a liquid envelope which accompanies it in the form of a coaxial jet.
  • the subject of the invention is a device for separating a long product in movement from a liquid jet which envelops it, constituted by a box having a lateral opening. line through which the product and the surrounding jet penetrate, a lateral orifice in alignment with said opening to allow free passage to the product and a lower outlet for the evacuation of the recovered liquid, the box internally comprising means for weakening the liquid jet surrounding the moving product having an axial recess for the free passage of the moving product and achieving a reduction in the thickness of the jet surrounding the product and means for causing shearing of said jet, device characterized in that the means to weaken the jet consist of at least one element, placed at a distance from the lateral opening through which the product and the jet surrounding it enter the box, and in that the box presents externally in the immediate vicinity of the orifice passage of the product, means for additional drying of the moving product constituted by a blowing member directing the product at least u n gas jet.
  • the power of the secondary jet necessary to obtain an effective shearing effect, could be such as it would be to fear, first certain difficulties in guiding the product, by deflection of the head at the time of its introduction into the separator, then a bending of the product (in particular for the products of small diameter) at the point d impact of the jet. It is therefore desirable to be able to operate with a secondary jet of moderate impulse, which involves acting on a previously weakened main jet.
  • the shell 14 fulfills, with respect to the jet (referenced 17), an additional function of reflection by causing the cusp of a part 18 of the water of the main jet, a large fraction 19 of this turned back part then falling back on the jet upstream of the shell.
  • This "folded" portion 19 disturbs the jet before rolling and thus contributes favorably to its weakening.
  • the ferrule 14 fulfills its role of reflector only if its large base through which the jet 17 has a diameter greater than that of the jet.
  • FIG. 3 A second possible arrangement is illustrated in FIG. 3.
  • This variant embodiment is characterized by an arrangement of the frustoconical ferrules 14 so as to make them divergent in the direction of propagation of the main jet.
  • This time the reduction in thickness of the latter, is no longer done by rolling and reflection as in the previous variant but, as clearly shown in the enlarged view of Figure 6, by deflection of a peripheral annular layer 20; this deflection role is of course filled by the ferrule 14 which has a small base with a diameter smaller than that of the jet and whose beveled end 21 acts in a way, like an annular knife which "peels" the jet on its outskirts.
  • the peripheral annular layer 20 thus cut is then deflected by passing over the external face of the shell.
  • the means of weakening the jet can be produced differently insofar as they act on a free jet, that is to say where they are placed at a distance from the end of the tube through which the jet exits and in since they are constituted by a body having an axial recess allowing the free passage of the product while scrolling.
  • this recess has an internal profile converging in the direction of propagation of the jet and that its inlet end has a diameter greater than that of the jet, then that, in the case of the deflector variant (FIGS. 3 and 6), the condition to be respected resides in the divergent form, in the direction of propagation of the jet, of the external profile of the means used.
