Definitions

  • the invention relates to a contact belt dryer, consisting of an endless conveyor belt for transporting a product to be dried, a lower heating plate arranged below the conveyor belt, an upper heating plate arranged above the conveyor belt, a gas distribution device for hot gas, arranged between the conveyor belt and the upper heating plate, and one Gas extraction device.
  • Contact belt dryers are used, for example, for drying dyes and pigments with frequent product changes.
  • the task was therefore to significantly increase the evaporation performance of the contact belt dryer without impairing the ease of cleaning.
  • This object is achieved in that the upper heating plate is alternately blown with hot gas from one side on the entire underside and overflowed.
  • the contact belt dryer consists of an endless, driven conveyor belt 1, which is deflected via two rollers 2.
  • a lower heating plate 3 is arranged below the conveyor belt and an upper heating plate 4 is arranged above the conveyor belt.
  • the product 5 to be dried migrates through the contact belt dryer during the drying process.
  • Hot gas 7 flows into the contact belt dryer via the gas distribution device 6.
  • the gas distribution device consists of a pipe 6a for the gas inlet and two parallel gas outlet pipes 6b arranged between the conveyor belt and the upper heating plate - connected to the pipe for the gas inlet - which correspond to the length of the upper heating plate and which are equipped with lances or nozzles 6c. These lances or nozzles are staggered in bundles on both gas outlet pipes and are arranged below approx.
  • This gas / vapor mixture is sucked out of the contact belt dryer via the gas suction device 8.
  • the speed of the outflowing gas should be 1-2 m / sec, based on the free cross-section.
  • the distance between the conveyor belt and the upper heating plate should be between 50 and 400 mm.
