Definitions

  • printing cylinders which have a very engraved surface finely and which have very small cells or sluices that are loaded with ink and small impurities that require scrupulous cleansing that must be both complete and leave the print surface intact.
  • the nozzle described in document FR 2712826 comprises a channel which has two sections, the first, in the direction of flow, being convergent and receiving directly the flow of particles, and the second being divergent.
  • the present invention makes it possible to create a media flow without margins irregularities, which makes it possible to juxtapose successive stripped strips rigorous, without any risk of irregularities and accidental attack of a layer that one wishes to preserve in its complete integrity.
  • FIG. 1 to 8 there is shown a nozzle according to the invention shown in one piece, being specified that it could also be obtained by assembling several sections, in particular to facilitate the machining of an axial internal passage of which the section is variable, as will be described now.
  • the nozzle is formed of a body 1 crossed by a longitudinal tubular passage, one of which end is an inlet 2 to be connected to a pipe power supply (not shown) for driving media to the input 2 according to the F1 arrow, media composed of solid particles in a gaseous medium, in particular the air.
  • the section of the passage 1 between the inlet 2 and the outlet 3 is variable, and the body 1 is externally formed of two segments which are a cylindrical segment 4 from the inlet 2 and a flattened nose 5 connected to the cylindrical segment 4.
  • the passage 1 has three parts which are successively: entrance chamber 11 with a constant circular section along the entire length of said chamber 11, an intermediate duct 12 of variable section continuously, its walls being convergent from the chamber 11 to an oblong neck 13, having therefore a small axis and a major axis, but whose area is equal to that of the chamber 11, and finally an output tube 14 with an oblong section of continuously variable section, walls being divergent from the neck 13 to the outlet 3, constituted by the end 5, and forming an outlet 15 which has an oblong section of shape different from that of the neck 13, the shapes of the neck 13 and the outlet orifice 15 being both coordinates so that, while having equal areas, the media flow is projected in a homogeneous and precise way, without suffering parasitic wall effects which are the cause of irregular margins.
  • the oblong section of the neck 13 has a very simple shape, since it has two parallel rectilinear edges 21 and 22 connected by 23 and 24.
  • the spacing of the rectilinear edges 21 and 22 is constant and the flow of media is evenly flat.
  • the passage section of the outlet orifice 15 is coordinated to that of the neck 13 to rectify this defect.
  • the passage section of the orifice 15 has a portion central with two parallel straight edges 25 and 26 connected not by holidays but according to arcs of circle 27 and 28 of larger diameter, creating two side channels longitudinal 29.
  • the spacing of the rectilinear edges 25 and 26 is smaller than that of edges 21 and 22, the total area of the two channels 29 being correlatively larger so that the section overall passage of the outlet orifice has an area equal to that of the neck 13.
  • Equality of the passage sections of the chamber 11, the neck 13 and the outlet orifice 15 guarantees a constant flow between the inlet 2 and the outlet 3 but the different forms that presents the central passage from the outlet of the chamber 11 to the orifice 15, give the media flow a two-phase flow with a homogeneous energy on the entire passage section of the outlet through a rational distribution of forms that compensate for wall effects and homogenize the flow.
  • the outlet jet is formed according to a flattened brush in which the energy is also distributed, whether the nozzle is operated manually or mechanically by a slave device.
  • FIGS. 9 to 16 there is another embodiment of the nozzle according to the invention.
  • the same elements bear the same references as in Figures 1 to 8.
  • the solid particles of the flux are charged in static electricity by the fact of their friction against the walls of the feed pipe and against the the walls of the nozzle, which is very troublesome because the particles are attracted by the surface in stripping and some of them remain stuck, so perform a finish consisting of cleaning the etched surface, meticulous work, painful and long.
  • this disadvantage is remedied by arranging oblique passages 33 and 34 which pass through the wall of the spout 5 and to which ducts are connected (no represented) from an ionized air source.
  • This air is compressed and injected at a high speed, or even supersonic, according to the arrows F3, in the medium that flows in the beak 5.
  • a pipe feeds the air ducts and contains a crown of known type (not shown) producing in the air discharges electrical ones that cause it to ionize so that it contains as many ions negative than positive ions.
  • the air circulating in this pipe is advantageously conditioned to be slightly damp.
  • the nozzle according to the invention equipped with ionized air injectors provides great safety because the introduction of this air can not cause no electric shock and therefore does not create hazardous conditions of inflammation of the media because there is no creation of a potential difference, so no existence of an electric current and no rise in potential of the surfaces to stripped.
  • the nozzle is moved in translation in the direction of its longitudinal axis, at a distance and angle of attack that depend on the substrate to be removed and the desired result.
  • FIGS. 9 to 16 it has been chosen to unblock the intermediate duct 12 in a neck 40 whose oblong passage section is elliptical.
  • the section of the outlet must have dimensions and shape coordinated with those of the neck 40, and we see FIGS. 10 and 14 show that the outlet orifice 41 has a passage section whose shape could be defined as a "counter-ellipse", that is, the section of passage of the orifice 41 is formed by two curved longitudinal edges 42 and 43 opposed by their convexity and connected by enlarged curves 44 and 45 which create the longitudinal side channels 29, so that the central part of the orifice 41 is narrower than the lateral parts, being reminded that the total area of orifice 41 is equal to that of the collar 40.
  • a passage section whose shape could be defined as a "counter-ellipse"
  • the section of passage of the orifice 41 is formed by two curved longitudinal edges 42 and 43 opposed by their convexity and connected by enlarged curves 44 and 45 which create the longitudinal side channels 29, so that the central part of the orifice 41 is narrower than the lateral parts, being reminded that the total area of orifice 41 is equal to that of the
  • the curves 44 and 45 do not continuously connect the edges 42 and 43, in an arc of circle for example, but are in broken arc and create at their intersection a ridge respectively 46 and 47, which creates a precise limit to the edges of the media stream leaving through the orifice 3.
  • the conjugate shapes of the neck 40 and the outlet orifice 3 again make it possible to distribute the energy of the flux uniformly, with a focus on particle velocity in the central area of the beak 5 and the flow on its two short sides.
  • the neck 13 of FIG. 17 is that which has been described with the first embodiment FIGS. 1 to 8. With reference to FIG. 17, it can be seen that the outlet orifice 15 coordinated at neck 13 is that also described with the first embodiment Figures 1 to 8.
  • FIG. 19 shows an oblong neck 50 which also has rectilinear edges, as in Figure 17, but each of them is formed by two segments 51-52 and 53-54 angularly offset to have a variable spacing from a minimum on sides up to a maximum in the central area.
  • an exit orifice of opposite shape namely that it has two straight edges each formed by two segments 55-56 and 57-58 angularly offset to the inverse segments 51-52 and 53-54 whose spacing varies from a maximum on the sides to a minimum in the central area.
  • FIG. 21 shows the neck 40 of FIG. 15 and in FIG. output of Figure 14.
  • the neck can have different shapes, from that of Figure 17 to rectilinear and parallel edges, up to the perfectly geometric ellipse shape of Figure 21.
  • outlets having a shape coordinated with that of the corresponding neck may also be made according to different variants, being recalled that the area the passage section of the outlet must be equal to that of the neck.
