Definitions

  • the invention relates to painting systems, in particular with painting systems for coating vehicle bodies with paints, with measures to minimize education of paint solvent condensate in a so-called cooling zone a paint shop.
  • so-called cooling zone a paint shop.
  • water-based paints still a small proportion contain organic solvents.
  • Such a painting system has an essential component a tunnel-like row of cabins by one to be painted Item, such as a vehicle body, one after another be run through; a sponsor extends for this purpose through the cabin row, with the help of which to Painted objects transported through the paint shop become.
  • the Solvent vapors generated in the dryer are removed from the Aspirated dryer and z. B. burned before the dryer exhaust is derived outdoors.
  • Located behind the dryer also a tunnel-like cabin Cooling zone in which the painted and dried Objects are cooled.
  • the dryer will run continuously operated, it is necessary for thermal separation the dryer of cold areas adjacent to the latter to provide the paint shop with a lock, which also over a tunnel-like, traversed by the objects Has cabin, in the usually heated fresh air is blown in to form a kind of air curtain which the objects are passed through. Still can do not prevent solvent vapors from entering the cooling zone, those from the painted items from the dryer be dragged into the cooling zone and / or during transport the painted objects from the dryer into the cooling zone exit the dryer and enter the cooling zone.
  • the invention was based on the object of practical measures to propose the formation of Paint solvent condensate in a cooling zone of a paint shop can be avoided or at least significantly reduced.
  • the invention thus relates to a method for minimizing the Formation of paint solvent condensate in the ceiling area of a Cooling zone of a paint shop, which is a tunnel-like row of cabins with at least one paint application booth, a heated one Dryer for drying painted objects and one through the dryer in the direction of passage of the objects the cooling system downstream cooling system for cooling the has painted and dried objects, the Cooling zone a tunnel-like cooling zone cabin with side walls, has a floor and a ceiling, which is between an inlet and an outlet opening of the cooling zone cabin extend for the painted objects.
  • the heating air flow can in the cooling zone cabin rising solvent vapors dissipated immediately before they reach the cabin ceiling, and / or the cabin ceiling is heated by the hot air flow so that does not form on this solvent condensate and as a result the solvent vapors are removed from the cooling zone without being even partially on the cabin ceiling condense.
  • the painted objects in the cooling zone are proportionate cool quickly and from the painted objects into the Solvent vapors introduced in the cooling zone already in the inlet area climb up the cooling zone, it is usually enough, only to apply hot air to the inlet area of the cooling zone cabin; but it is also considered to be under the present invention falling when viewed at the bottom of the cabin ceiling adjacent area of the cabin interior over the the entire length of the latter is supplied with hot air or if there is heating air at several points along the cooling zone cabin introduced into the cabin interior and elsewhere is discharged from the cabin interior.
  • the method according to the invention is successful heating the ceiling of the refrigerator compartment ahead; however, the method according to the invention is preferred designed so that at least in the cabin entry area Underside of the ceiling of the refrigerator zone by the heating air is heated.
  • the heating air flow could, for. B. at a clear distance below the cabin ceiling are introduced into the cabin room so that the heating air from below against the cabin ceiling flows.
  • embodiments are preferred in which the heating air flow immediately under the cabin ceiling and approximately introduced parallel to this in the cabin interior solvent vapors rising in the cabin interior dissipate by a laminar flow of hot air and to prevent the solvent vapors together with the Hot air flows onto the cabin ceiling.
  • the method according to the invention in this way shape that the heating air flow immediately next to the cabin inlet opening introduced into the cabin interior and the heating air loaded with solvent vapor immediately below the cabin ceiling at at least one point in the cabin interior is discharged, which - in the longitudinal direction of the cabin measured - a relatively short distance (on the cabin length) from the cabin entrance opening Has.
  • a particularly effective and low-energy embodiment of the method according to the invention stands out characterized in that several from the two sides of the cabin Heating air flows in the adjacent to the bottom of the cabin ceiling Area of the cabin interior and the heating air loaded with solvent vapor at the two Cabin sides is discharged, so that in the cabin interior areas of the hot air flow paths - in the Seen from above the cooling zone - roughly arched or C-shaped, because then there is a special one efficient rinsing of the inlet area of the cooling zone as far as possible laminar flow.
  • the cabin ceiling can be easily heat effectively by first heating the heating air over guided the top of the cabin ceiling and heated the latter before the heating air is introduced into the cabin interior becomes.
  • the invention also relates to the structural design a cooling zone for a painting installation of the type described above Kind, being proposed to solve the task is to design the cooling zone so that at least an inlet area adjacent to the inlet opening Cooling zone cabin an air supply device for heated Air (hot air) is assigned to which air guide means to act on one adjacent to the underside of the cabin ceiling Area of the cabin interior with hot air, and that at least in the upper area of the cabin interior a hot air outlet for leading with paint solvent vapor laden heating air is provided.
  • heated Air heated Air
  • a ventilation device is associated with arranged in the cabin side walls Blow nozzles for loading the painted objects with blown air as well as in the transition areas between Cabin side walls and cabin ceiling arranged air extraction openings, can be suctioned off with solvent vapor manage laden heating air without any additional effort, by the air extraction openings also the function of the Take over heating air outlets.
  • the cost of implementation can be reduce the invention even further when a partial flow of heated air generated for this air curtain to the invention Rinsing the cooling zone is used.
  • FIG. 1 shows one standing on a hall floor 10 Outside cabin 12, one designated as a whole by 14 Cold room cabin accommodates.
  • Both the outside cabin 12 as well the cooling zone cabin 14 are designed tunnel-like, their Longitudinal directions run perpendicular to the plane of the drawing Fig. 1.
  • the cooling zone cabin 14 is not in a Detail drawn floor 16, which is also the floor of the Refrigeration zone cabin forms, which also two side walls 18 and has a blanket 20.
