Definitions
- the printing cylinders which have a very engraved surface finely and which contain very small cells or holes which become charged with ink and small impurities which require scrupulous cleaning which must both be complete and leave the printing surface intact.
- the present invention makes it possible to create a media stream without irregular margins, which which allows to juxtapose the successive stripped strips in a rigorous way, without no risk of irregularities and accidental attack of a desired layer preserve in its complete integrity.
- Figure 1 is a schematic view in longitudinal section of a nozzle according to the invention.
- Figures 2, 3 and 4 are schematic cross-sectional views of the nozzle of the Figure 1, each arranged vertically from where it is located.
- FIG. 5 is a schematic view in longitudinal section of the same nozzle, made at 90 ° from the section in Figure 1.
- Figures 6, 7 and 8 are schematic cross-sectional views of the nozzle of the Figure 5, each arranged vertically from where it is located.
- FIG. 9 is a schematic view in longitudinal section of a nozzle conforming to the invention, according to a particular embodiment.
- Figures 10, 11 and 12 are schematic cross-sectional views of the nozzle in Figure 9, each arranged vertically from where it is located.
- FIG. 13 is a schematic view in longitudinal section of the same nozzle, made at 90 ° to the section in Figure 9.
- Figures 14, 15 and 16 are schematic cross-sectional views of the nozzle of Figure 13, each arranged vertically from where it is located.
- Figures 17, 19 and 21 show, in cross section of the nozzle, three variants of shape of the oblong neck.
- Figures 18, 20 and 22 show three variants of the shape of the outlet each corresponding to the shape of the oblong neck shown opposite, i.e. neck of Figure 17 and outlet of Figure 18, neck of Figure 19 and port of outlet of figure 20, neck of figure 21 and outlet orifice of figure 22.
- the nozzle is formed by a body 1 crossed by a longitudinal tubular passage, one of which east end constitutes an inlet 2 to be connected to a pipe supply (not shown) to conduct media to input 2 according to the arrow F1, media composed of solid particles in gaseous medium, in particular of the air.
- an outlet 3 through which the media is projected according to arrows F2 on a surface in order to strip it with one or more layers that she wears.
- the section of passage 1 between inlet 2 and outlet 3 is variable, and the body 1 is externally formed from two segments which are a cylindrical segment 4 from the inlet 2 and a flattened spout 5 connected to the cylindrical segment 4.
- passage 1 has three parts which are successively: a inlet chamber 11 with constant circular section over the entire length of said chamber 11, an intermediate duct 12 with continuously variable section, its walls being convergent from the chamber 11 to an oblong neck 13, having so a minor axis and a major axis, but whose area is equal to that of chamber 11, and finally an outlet tube 14 with oblong section with continuously variable section, is walls being divergent from the neck 13 to the outlet 3, constituted by the end of the spout 5, and forming an outlet orifice 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 manner, without undergoing 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 leaves 23 and 24.
- the spacing of the straight edges 21 and 22 is constant and the flow of media is uniformly flat.
- the passage section of the outlet orifice 15 is coordinated with that of the collar 13 to rectify this defect.
- the passage section of the orifice 15 has a part central unit with two parallel rectilinear edges 25 and 26 connected not by fillets but along arcs 27 and 28 of larger diameter, creating two lateral channels longitudinal 29.
- the spacing of the straight edges 25 and 26 is smaller than that of the edges 21 and 22, the total area of the two channels 29 being correspondingly larger so that the section of the entire outlet orifice has an area equal to that of the neck 13.
- the outlet jet is formed according to a flattened brush in which the energy is also distributed, whether the nozzle is actuated manually or mechanically by a slave device.
- FIGS. 9 to 16 we see another embodiment of the nozzle according to the invention.
- the same elements bear the same references as in FIGS. 1 to 8.
- chamber 11 there are two oblique plungers 31 and 32 which "disturb" the random input stream in order to homogenize it and concentrate it to prepare it for approach the neck with oblong section.
- the solid particles of the flux are charged with static electricity by the fact of their friction against the walls of the supply line and against nozzle walls, which is very annoying because the particles are attracted to the surface by pickling course and part of it sticks to it, so you have to proceed to a finish consisting of cleaning the pickled surface, meticulous work, painful and long.
- this drawback is remedied by providing oblique passages 33 and 34 which pass through the wall of the spout 5 and to which conduits are connected (not shown) from an ionized air source.
- This air is compressed and injected at high speed, or even supersonic speed, depending on the arrows F3, in the medium which circulates in the spout 5.
- a pipe (not shown) supplies the air ducts and contains a crown of known type (not shown) producing discharges in the air electrics which cause its ionization 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 job security because the introduction of this air cannot 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, therefore 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 at an angle of attack which depend of the substrate to be removed and the desired result.
- the section of the outlet must have dimensions and a shape coordinated with those of the collar 40, and we see on Figures 10 and 14 that the outlet 41 has a passage section whose shape could be defined as a "counter-ellipse", that is to say that the section of passage of the orifice 41 is constituted by two curved longitudinal edges 42 and 43 opposite by their convexity and connected by widened 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, it being recalled that the total area of the orifice 41 is equal to that of pass 40.
- a passage section whose shape could be defined as a "counter-ellipse"
- the section of passage of the orifice 41 is constituted by two curved longitudinal edges 42 and 43 opposite by their convexity and connected by widened 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, it being recalled that the total area of the orifice
- curves 44 and 45 do not continuously connect edges 42 and 43, in an arc of circle for example, but are in a broken arc and create an edge at their intersection 46 and 47 respectively, which creates a precise boundary at the edges of the media stream exiting through port 3.
- the combined shapes of the neck 40 and the outlet orifice 3 again allow distribute the energy of the flow evenly, favoring the speed of the particles in the central zone of the nozzle 5 and the flow on its two short sides.
- 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 to a maximum in the central area.
- an outlet port of opposite shape namely that it has two straight edges each formed by two segments 55-56 and 57-58 offset angularly in reverse segments 51-52 and 53-54 whose spacing varies from a maximum on the sides up to a minimum in the central area.
- FIG. 21 shows the neck 40 of FIG. 15 and in FIG. 22 the orifice of output from figure 14.
- the collar can have different shapes, from that of Figure 17 to straight and parallel edges, up to the perfectly geometric elliptical shape of Figure 21.
- outlet orifices having a shape coordinated with that of the corresponding neck, this shape can also be produced in different variants, it being recalled that the area of the passage section of the outlet orifice must be equal to that of the neck.
