Definitions

  • the invention relates to a system according to the preamble of the main claim.
  • the invention has for its object to provide a system for drying components, such that work can be carried out in the drying cabin at high air speeds without the risk that solid particles are thrown through the air outlet nozzles onto the object to be dried.
  • the invention proposes a drying cabin, which is equipped in the usual way with a supply air duct in which A corresponding preliminary, intermediate and main filtering takes place in the usual way at low outflow speeds.
  • the drying booth is formed in the area of its surrounding wall by a clean air duct or clean air space, nozzles being arranged in the wall which is arranged towards the interior of the drying booth.
  • a separate filter element which is designed as a fine filter cartridge and which can be easily exchangeably attached to the inside of the inner wall of the drying cabin, is connected upstream of the nozzle in the drying cabin.
  • Fine filter cartridges which are particularly equipped with a pleated filter element, have a high throughput and effectively prevent deposits located between the last filter mat and the nozzle outlet from entering the nozzle outlet and then with the high air outlet speed of approx. 20 m / sec. to be hurled onto the object to be dried.
  • the arrangement of the large number of fine filter cartridges has the advantage that large amounts of air can be passed through, but on the other hand these large amounts of air can be filtered or cleaned in the smallest space.
  • Filter paper can be used as the filter material for the fine filter cartridges, but the filter cartridges are preferably formed from plastic fiber fleeces, which have the advantage of high heat resistance, so that hot or hot air can also be used in the system according to the invention.
  • the system according to the invention has the advantage that the disadvantages of solvent-based paints can be avoided by the increased air outlet speed with completely solids-free drying air with the same drying times as when used with solvent-based paints, and an environmentally friendly process can thus be created.
  • the invention enables the use of environmentally friendly paints and also makes it possible to clean the drying air with suitable space-saving fine filter cartridges or fine filter elements and to achieve high air speeds.
  • the invention is not limited to the application for motor vehicle bodies, but the invention can be used in the same way, for example, in the furniture industry, in the plastics industry or in other industries in which problems of the type shown above occur.
  • Fig. 1 denotes a drying cabin, the wall of which is designed as a clean air duct 2.
  • the inner wall 5 of the clean air duct carries a plurality of nozzles 3, while the outer wall 4 of the clean air duct 2 is closed.
  • a supply air duct 6 opens into the clean air duct 2, the air flowing in this supply air duct 6, which is possibly also provided with impurities, being marked with a semi-black arrow F 1 in the drawing.
  • the air introduced from the supply air duct 6 through the nozzles 3 into the drying cabin 1 flows as clean air, for example via the outlet openings 7 to an exhaust air duct 8, this clean air being identified by a full white arrow F2.
  • fine filter cartridges 9 are arranged, which ensure that between the ones arranged in the supply air duct 6, in the drawing Solid filter particles entrained with the conventional filter device (not shown) and the nozzle outlet are separated and prevented from escaping from the nozzles 3.
  • Fig. 2 shows the arrangement of the fine filter cartridge 9 on a larger scale.
  • the nozzles 3 are fixed on the inner wall 5, the inner wall 5 or the nozzle 3 having a fixed flange 10 which is equipped with an internal thread into which an external thread 11 connected to the fine filter cartridge 9 can be screwed.
  • the fine filter cartridge 9 consists, in a manner known per se, of a support basket 12, which carries, for example, a pleated filter 14 on its outside, which is fixed to the support basket 12 via corresponding holding means 15. While the support basket 12 is open towards the nozzle 3, the support basket 12 is closed at the rear end at 16, so that the air is forced to enter the nozzle only after it has passed through the pleated filter 14.
  • the support cage 12 is equipped in a manner known per se with corresponding air passage openings 17.
  • a seal is shown at 18 that safely prevents any false currents.
  • the design of the fine filter in front of the nozzle 3 as a pleated filter cartridge provides a very large filter area which is sufficient to achieve the required air acceleration within the nozzle 3, although air speeds of only about 2 m / sec. In the supply air duct. are available.
  • the threaded connection between the fine filter cartridge 9 and the inner wall 5 or the nozzle 3 makes it easy to replace the fine filter cartridge 9, so that after a certain period of time it is easy to replace the used filter elements.
  • the arrangement according to the invention achieves fine filtering directly in front of the air outlet nozzle 3 and, on the other hand, enables a high air outlet speed from the nozzle 3 with a small space requirement at the installation location and thus ensures that on the one hand the required air speed for drying the surfaces can be achieved is, so that the components can be dried in economically justifiable periods of time, while on the other hand it is excluded with certainty that the surface of the components to be dried is contaminated in any way by entrained solid particles.
  • the configuration according to the invention also ensures that, by designing the inner wall 5, for example in the lower region of a motor vehicle body to be dried, adaptations to the shape of the body are possible, as is the case through the step-like configuration of the inner wall at 19 is recognizable. This makes it possible to direct the air to particularly difficult to dry component areas.
