Definitions

  • the present invention relates to machines for treating and in particular cooling sheets or other similar products, of the type comprising a lower frame and an upper frame in which are mounted sets of rollers for driving and guiding the sheet, operating in pairs. , the two frames delimiting an enclosure in which a treatment fluid circulates.
  • Such a machine is described in particular in French patent n ° 73 10 710 of March 26, 1973 and in French patents n ° 77 39 833, 77 39 834, 77 39 835, 77 39 836 filed on December 30, 1977.
  • FIG. 1 the inlet end of a plate cooling machine comprising an upper frame 10 and a lower frame 20.
  • Each frame has side walls 11, 21 connected by metal envelopes 12, 22 comprising roughly flat parts 12-, 22a parallel to the sheet to spend in the machine and the curved portions 12 b, 22 b around the drive rollers 13,23 and guide.
  • the metal envelopes delimit an enclosure E in which a coolant can circulate, the enclosure being for this purpose connected to inlet and outlet conduits for this liquid, the conduits 14, 24 shown in the drawing being in the occurrences of the outlet conduits.
  • the entry end of the machine is closed by one or more rigid flaps 30 moving approximately vertically, that is to say perpendicular to the direction of passage of the sheet.
  • flaps 30 moving approximately vertically, that is to say perpendicular to the direction of passage of the sheet.
  • a box beam 32 constituting a fluid reservoir is disposed between the two side walls 11 of the upper frame.
  • This beam contributes to the rigidity of the machine and it is connected at its upper part to a source of fluid which, in the example shown, may be water.
  • the lower wall 33 of this tank located in the extension of the flat horizontal wall 12- of the upper frame and fixed to this wall by any suitable means, delimits a slot 34 which is inclined relative to the horizontal so as to direct a thin layer of water towards the interior of the machine.
  • the inclination of the slot relative to the horizontal is between 10 and 20 °, preferably of the order of 15 °.
  • the slot has a thickness which can be of the order of 1 to 3 mm.
  • the box 32 has a wall 3 6 inclined, at 45 ° for example, to ensure possible guidance of the product entering the machine.
  • a recovery tank 40 is provided at the lower part of the machine, this tank being delimited by a box connecting the two side walls 21 of the lower frame of the machine and the upper wall of which is here constituted by the horizontal wall 22a of the envelope.
  • This box has an opening 41 of relatively large dimension, extending over the entire width of the machine and also extending to the vicinity of the shutter 30.
  • the opening 41 is preferably covered by a grid 41 a .A its lower part, this box is connected to conduits 42 for discharging the recovered liquid.
  • the reservoir 32 When a sheet has to enter the machine, the reservoir 32 is supplied and projects a roughly flat water jet whose speed can be of the order of 4 to 6 m per second, this jet being directed towards the inside the machine at an angle, which, as indicated above, can be of the order of 10 to 20 °.
  • this jet of water tends to oppose the outward flow of the coolant contained inside the machine. Furthermore, having a certain vertical component, it folds down this liquid which is thus more effectively recovered in the tank 40.
  • the jet continues to fulfill this same function but the water is then evacuated towards the sides of the machine, this function being further improved by the orientation of the deflectors 35.
  • the water jet projected by the reservoir 32 fulfills the same function as above and opposes the flow of the liquid contained in the machine by folding it back to the recovery tank.
