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, this enclosure being closed at its two ends by movable flaps extending between the upper frame and the lower frame.
  • Such a machine is described in particular in document FR-A-2 413 141.
  • the purpose of this invention is therefore to provide an effective solution to this sealing problem.
  • a machine for cooling sheets or the like of the type comprising an upper frame and a lower frame each comprising two side walls connected by a delimiting envelope.
  • an enclosure in which a coolant circulates this enclosure being closed at its two ends by movable flaps extending between the upper frame and the lower frame, characterized in that it is provided at each end of the machine and outside the enclosure, on the one hand, a coolant recovery tank, carried by the lower frame and extending over the entire width of the machine, and on the other hand, means carried by the upper frame and arranged to project towards the interior of the machine a jet of fluid, directed against the current of the liquid tending to leave said machine.
  • 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 12a, 22a parallel to the sheet to spend in the machine and the curved portions 12 b, 22 b around the drive and guide rollers 13, 23.
  • the metal sheaths delimit a chamber in which may circulate a cooling liquid, 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 this case 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 sheet metal.
  • flaps 30 moving approximately vertically, that is to say perpendicular to the direction of passage sheet metal.
  • 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 reservoir located in the extension of the flat horizontal wall 12a 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 blade of thin 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 36 inclined, at 45 ° for example, to ensure possible guiding 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 41a.
  • this box is connected to conduits 42 for evacuating the recovered liquid.
  • the water supply to the upper tank 32 can be shut off.
  • the residual leaks which can occur if the screen formed by the flaps 30 is not strictly sealed are collected in the tank 40 and evacuated.
  • 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 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 recovered more efficiently 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 s opposes the flow of the liquid contained in the machine by folding it towards the recovery tank.
