Definitions

  • the present invention relates to an improvement made to the installations for treating sheet materials with water jets under pressure, which act on the structure in the manner of needles, used especially for treating non-woven structures in order to give them cohesion and / or change its appearance.
  • One of the essential elements of such facilities is the training system jets or water needles, commonly referred to as "injector”.
  • the invention relates more particularly to a new type of injector.
  • such injectors are therefore in the form of a ramp, continuous, extending transversely to the direction of travel of the sheet material (F) to treated, for example, non-woven, and whose length is adapted to the width of said material.
  • This ramp can either consist of a single elementary module or a plurality of modules juxtaposed to each other.
  • Such a ramp consists of a main body (1), making it possible to withstand any deformation under the pressure of the water, at the top of which is made a chamber (2), generally of cylindrical shape, fed with water under pressure through a pipe (3) fed by a pump (no shown).
  • a cartridge (4) constituted by example by a perforated cylinder lined with a filter cloth, which not only plays the filter role, but also serves as a dispatcher.
  • the pressurized water introduced inside the chamber (2) then flows through cylindrical holes (5), spaced with a regular pitch over the entire width of the injector, a hole whose diameter is generally between 4 mm and 10 mm, the thickness of the wall between two consecutive holes being of the order of 3 to 5 mm.
  • These cylindrical bores (5) whose exit end can possibly be of conical shape, then open into a lower chamber (6) at the base of which is positioned a plate (7) provided with micro-perforations, of which the diameter may be between 50 and 500 ⁇ m and preferably between 100 and 200 ⁇ m, for forming jets of water or needles (8) which act directly against the surface of the material (F), nonwoven web for example, to treat.
  • Holding the perforated plate (7) against the main body of the injector is obtained for example according to the teachings of EP 400249 by intermediate longitudinal jaws (9) subjected to the action of hydraulic cylinders which make it possible to exert a clamping action through a set of pedals and tie rods arranged along the injector.
  • a seal (not shown) is disposed between the perforated plate (7) and the base of the main body (1).
  • Such a system for dispensing water under pressure against the micro-perforated plate intended to form the water needles and which therefore uses holes (5) which open into a lower chamber (6), distributes the water correctly over the entire length of the injector, the same flow of water passing through through each orifice.
  • FIG. 2 schematically illustrates the reasons for such defects.
  • the space between the two side walls defining the distribution channel is advantageously between 2 mm and at most 10 mm, the height of the walls being, for its part, between 5 mm and 100 mm, the jets produced through micro-perforations having, thanks to such a structure, an identical energy output and this, over the entire treatment width.
  • the injector according to the invention consists, in a manner similar to this state of the art, of a main body (1) made of steel, having a length of 3500 mm, a total width of 200 mm, and a height of 200 mm.
  • this body In the upper part of this body is made a cylindrical chamber (2) having a diameter of 70 mm. This room is supplied with pressurized water. through a pipe (3).
  • the water supply is illustrated as being done laterally, but it could be done from the top of the body or the back.
  • a cartridge (4) constituted by a perforated cylinder coated with a filter cloth.
  • a micro-perforated plate (7) produced, in the present case, by a steel strip 1 mm thick, 25 mm wide and with at least a row of orifices, the diameter of which is preferably between 100 and 200 ⁇ m and which are spaced from a distance between centers in general between 0.6 and 1.2 mm.
  • Sealing means joints (23) for example, are of course provided between the base (20) of the upper body and the surface of the micro-perforated plate (7).
  • the transfer of water under pressure to the plate (7) formation of water jets is obtained through a channel (22) extending from the periphery of the chamber (2) to the surface of the micro-perforated plate (7).
  • This split channel consists of two opposite parallel walls (21) spaced apart each other by a distance of between 1 mm and a maximum of 10 mm, the height being, meanwhile, between 5 mm and 100 mm. This split channel is closed laterally.
  • the injectors of the prior art as illustrated in FIG. 1 have the following characteristics: diameter of the upper chamber (4) 50 mm diameter of the ducts (5) 6 mm distance between two consecutive ducts (5) 10 mm height of ducts (5) 35 mm height of the lower chamber (6) 10 mm micro-perforated plate having a single row of micro-perforations of 120 ⁇ m, spaced from each other by 0.6 mm
  • the micro-perforated plate is also constituted by a plate comprising 120 ⁇ m orifices, spaced from each other by 0.6 mm.
  • This veil is subjected to the action of two injectors acting successively against both sides of the veil.
  • Water is fed inside the upper chamber of each type injector by gradually increasing the supply pressure.
  • the injector according to the invention makes it possible to obtain a tablecloth perfectly bonded, without apparent defect, for a supply pressure reach 400 bars.
