Definitions

  • the invention relates to industrial heating tunnels, in particular for drying or polymerizing various products, in particular paint, and more particularly heating tunnels by means of infrared radiation.
  • Infrared tunnels are usually of two types: the first type uses near infrared or light rays emitted by infrared lamps, the main drawback of which is the short lifespan.
  • the second type uses far or dark infrared emitted by electrical resistances embedded in radiant cast iron panels, which have the main disadvantage of having a fairly low infrared efficiency.
  • the construction of the complete tunnel provided with these panels leads to a heavy and expensive construction.
  • the object of the invention is to eliminate the above drawbacks by providing a relatively light and economical tunnel construction, which combines both a long service life and a high efficiency as well as a low thermal inertia.
  • the construction of the tunnel according to the invention begins with the construction of the framework, as shown in FIG. 3, using sections of metal tube assembled together in three dimensions using assembly means known to themselves and not forming the subject of the present invention.
  • the entire framework, designated by 1 in FIG. 3 is built from horizontal beams 2 in profile arranged at the base on the ground to receive the tunnel and serving to fix the lower end of the tubular uprights of the frame.
  • the entire framework 1 could also be suspended from any frame.
  • the current vertical panels 5 themselves consist of interior panels 6 and exterior panels 7, both made of sheet steel, preferably stainless steel and of small thickness.
  • the exterior panels 7 are simple rectangular panels having four edges which have fallen towards the interior of the tunnel, two of these horizontal edges 8 being wider than the others and terminated by profilings 9 in V whose concavity is turned towards the outside to allow to fit on the horizontal tubes 10 of the framework 1. This assembly is done naturally from the outside, by tilting around one of the tubes, playing on the elasticity of the metal.
  • These panels 7 comprise in advance a layer of insulation 11 preferably constituted by a rock wool mattress.
  • the interior panels 6 are completely identical in design, except that their V-shaped edges are vertical to fit onto the vertical tubes 12 of the frame 1.
  • the radiant panels as designated as a whole by 13 in FIG. 1 are of identical design to that of the current vertical panels 5 but have radiant elements 14 on the inside.
  • the interior panels 6a of these assemblies 13 are absolutely identical to the preceding panels 6, except that they include circular perforations 15 for mounting the heating resistors 16 and rectangular perforations 17 for mounting the radiant elements 18.
  • the latter consist of a stamped sheet metal part 18 provided with dropped edges 19 and stamped ribs 20 allowing the interlocking of the hairpin heating part of the armored resistors 16.
  • the parts 21 of the resistors 16 bent perpendicularly to the panel 6a pass through the latter through circular perforations 15.
  • the fallen edges 19 of the panel 18 also have fixing lugs 22 provided with a base wider than their end, this end being the only one to penetrate through the rectangular perforations 17 of the panel 6a, the wide parts consequently constituting spacers to maintain a sufficient distance between the end of the fallen edges 19 and the interior face of the panel 6a to allow possible circulation of air and do not require great precision in the flatness of these stamped edges.
  • the fixing is done by simple twisting of the narrow end of these legs.
  • the panels 6a like the panels 5, have horizontal fallen edges 23 and vertical fallen edges 24, the latter being extended by parts 9a profiled in V as described above.
  • the connection ends 21 of the resistors 16 easily pass through these rock wool mattresses to emerge above the panel 11b as shown in FIG. 1.
  • connection bars 25 of modular length which are fixed step by step on the threaded ends 26 of the parts 21 using ordinary nut.
  • the outer panels 7a which are identical to 7 are placed by elastic interlocking except that their horizontal fallen edges 27 are wider to make room for the electrical connections. Like the panels 7, they have edges 9b profiled like the edges 9 to allow elastic fitting onto the horizontal tubes 10 from the outside.
  • this tunnel is characterized by a very low thermal inertia thanks to the low mass of the radiant elements 14 and a very high infrared efficiency combined with a very long longevity due to the fact that these elements 16 resistants work at relatively moderate temperatures.
