Definitions

  • the preliminary dryer has means for guiding the cables in vertical direction, and is provided with infrared heating means and nozzles which blow hot air.
  • a very intensive drying takes place in the preliminary dryer so that the efliciency of the drying apparatus is increased, and the drying chamber, and particularly its floor area can be substantially reduced.
  • FIG. 1 is a schematic side elevation, partially in section, illustrating an apparatus according to the invention.
  • Nozzles 9, 10 penetrate vertical conduits 11, 12 which are advantageously divided into pockets.
  • a burner 13 is disposed for supplying hot combustion gases into conduits 12 and 11 in which infrared radiators are located which are heated by the combustion gases.
  • infrared radiator plates heated by combustion gases electrical or gas heated infrared heaters may be used.
  • the combustion gases and smoke flow in the direction of the arrows through conduits 11 and 12 and flow out of outlet 11a.
  • a rotary blower 14 produces a flow of air which passes through nozzles 9 and 10 and is blovm from opposite sides against portions 8a of the flexible means 8-.
  • the air blown into the preliminary drying chamber by blower 14 is heated by the walls of conduits 11 and 12. If necessary to avoid damage to the fibers of cables forming the flexible means 8, cooling air is blown into the preliminary drying chamber by blower 14 in increased amounts by setting blower 14 to a higher speed and a greater output.
  • the moist flexible means 8 After the moist flexible means 8 have passed through the preliminary drying chamber, they are guided over drums 15 and 16 which are disposed in the drying chamber 1a in an upper row of drums 15 and in a lower row of drums 16.
  • the flexible means passes over a drum 15, then over a drum 16 and again over the next drum 15 so that the opposite loops alternately open between two upper drums 15 and two lower drums 16, and have leg portions 8b extending between upper drums 15 and lower drums 16.
  • Drums 15 and 16 are hollow and perforated in the peripheral wall thereof, and are supported on shafts 15a and 16a which pass through walls 10! and 1c.
  • the front ends of drums 15 and 16 are free so that flexible means 8 can be easily placed on the same in axially spaced positions when doors and 51 are opened.
  • the upper and lower rows of drums 15 and 16 divide drying chamber 1a into a central chamber portion 40 and two chamber end portions 41 and 42.
  • a row of upper blower nozzles 20 and a row of lower blower nozzles 21 are provided and connected with distributing chamber 41b, 42b.
  • Each nozzle 20 is located in an open loop of flexible means 8 between two adjacent upper drums 15, and each nozzle 21 is located in another open loop between adjacent drums 16.
  • Each nozzle 20, 21 has two openings for blowing two air streams against the adjacent leg portions 8b.
  • the flexible means 8 may be further dried in a second drying chamber 1b as described for drying chamber 1a, and finally transported out of the apparatus by transporting rollers 45.
  • Apparatus for drying continuously moving elongated flexible means comprising, in combination, a drying chamber; first and second staggered rows of first and second rotary hollow perforated drums driven for transporting elongated flexible means guided alternately over first and second drums so as to form opposite loops which are alternately open between two adjacent first drums and two adjacent second drums and have leg portions extending between first and second drums and yoke portions located on said drums, said first and second rows of said first and second drums being located in said drying chamber and dividing the same into a central chamber portion and two chamber end portions located respectively outside of said first and second rows; blower nozzles located between adjacent drums and in said open loops; blower means including first and second blowers having first and second outlets respectively opening into said chamber end portions, and first and second inlets; heater means for heating the air moved by said blower means including first and second rows of heaters located in said chamber end portions of said drying chamber and dividing the same into first and second outlet spaces communicating with said first and second outlets, respectively, and
  • Apparatus as claimed in claim 1 comprising manually operable valve means between said distributing spaces and 6 said second conduit means for varying the ratio between the amounts of air flowing in said first and second conduit means and in said first and second drying circuits.
  • said casing means includes a conduit chamber connected with said first and second inlets of said first and second blowers, and a wall separating said drying chamber from said conduit chamber having openings communicating with said return conduit means.
  • nozzles include rows of first and second nozzles respectively located between pairs of adjacent first drums and second drums; and wherein said other first openings include two sets of first openings respectively connected with said first and second nozzles, and two sets of second openings respectively connected with said first and second drums.
  • Apparatus as claimed in claim 1 comprising drive means for rotating said first and second drums and being adjustable for varying the rotary speed of each drum for adjusting the tension of said open loops.
