Definitions

  • the invention relates, according to the preamble of claim 1, to an arrangement for cleaning the exhaust air from spray paint booths and is used in particular in so-called Venturi washout systems.
  • the washing liquid which absorbs the overspray and all other impurities e.g. production residues, such as film residues, plastic parts and the like, as well as other dirt particles, is fed to a collecting tank via one or more collecting troughs, partly disposed of and fed back into the feed system of the washing system.
  • Another problem of known systems is that, especially in the water distribution channels, which ensure a constant and uniform sprinkling of the wall and / or floor surfaces of the spray booths, a deposition of the solid particles occurs over time, which is then still expensive in the past Need to be eliminated from time to time.
  • FIG. 1 shows in cross section a spray paint booth with an arrangement underneath for cleaning the exhaust air according to the invention.
  • trickle plates 3 and 4 are predominantly arranged over the entire base area. These 3 and 4 are inclined on one side and partially overlap, creating an air duct 14.
  • the lower trickle plate 4 is provided with a weir 6 at its higher edge, which points toward the washout nozzle 11.
  • the elements 3, 4 and 6 are also arranged so that the air duct 14 is essentially off-center.
  • a collecting channel 8 which is preferably part of the pouring plate 4.
  • a so-called Venturi wash-out system is arranged downstream of these flow plates 3 and 4 and below these 3 and 4.
  • the washout nozzle 11 is arranged with a vertically oriented flow direction, and it itself 11 and the system of baffle plates following this 11, based on the cross section of the spray paint booth, are arranged eccentrically and under at least one pouring plate for sound-related reasons.
  • a further feed system 9 for washing liquid is assigned to the guide plates 10 upstream of the washout nozzle 11.
  • the exhaust air duct 15, which has previously been outside the basic dimensions of the cabin 1, is an integrated component according to the invention and is located under at least one trickle plate.
  • the waste air which is freed of waste, production residues or the like and is only loaded with the overspray, passes through the air duct 14 formed by the trickle sheets 3 and 4 to the washout nozzle 11.
  • the overspray is washed out of the exhaust air by these 11 and the downstream system of cutoff sheets 12 , the exhaust air itself dehumidified and extracted via the exhaust air duct 15.
  • the washing liquid mixed with the overspray is fed to a collecting tank via a trough 13.
  • the dirty washing liquid and the washing liquid containing the paint particles are thus clearly separated and disposed of or recycled in downstream systems.
  • the main advantages of the arrangement according to the invention are the reduction of the noise level, the reduction of the susceptibility to failure of the continuous production flow, one better prerequisite for an almost complete "overspray paint” recovery and in economically constructive savings such as the reduced space requirement.
  • the water film that is constantly in motion with this new technical teaching thus prevents any sedimentation on any of the components in a simple manner and thus enables continuous operation without pauses in cleaning and with the lowest circulating water volume.
  • distributor plates VT also inclined to the horizontal, extend over the entire length of the channel R and labyrinthine from both sides RS1 and RS2 of the channel R and partly overlapping Ü against each other directed and arranged at a distance A from one another
  • the distributor or baffle plates VT in their inclination angle ⁇ and / or their effective length L and / or overlap Ü as well as mutual height distance A can be changed or arranged on the channel walls RS 1 and RS 2 could be.
  • each collecting channel 8 is advantageously designed as a weir 6 'or 6''. This variant is mainly used when there is a lot of dirt.
  • cross-flooding of the flow plates 3, 4 and 3 ', 5 is carried out, i.e. the flow direction of the washing liquid on the flow plates 3, 3 ', 4 and 5 runs transversely to the workpiece transport direction.
  • system A As is known in previous venturi wash-out systems, the inventive arrangement can also extend under several spray paint booths, spray paint streets, hereinafter referred to as system A.
  • FIGS. 3 and 3a Compared to the aforementioned, longitudinal flooding is provided here.
  • the flow plates 3 and 4 are preferably inclined on one side in the longitudinal direction of the system A.
  • a pouring plate 4 ' is provided at the same height as the pouring plate 4, indicated by dashed lines in FIG. 3.
  • the correspondingly narrower pouring plate 4 is located below the pouring plates 3 and 4 '.
  • the collecting channel 8 for the dirty water liquid is preferably located on one and the supply system 7 on the opposite end S of the system A, see FIG. 3a.
