Definitions

  • the invention relates to a glaze spray booth with outer walls made of metal or water and gas-tight plastic.
  • the walls are made of metal, e.g. Nirosta, or made of plastic.
  • the known spray booths have the disadvantage that the cost of cleaning them is quite high.
  • the glaze residues must be sheared off the cabin walls, the glaze residues shoveled out of the cabin and the cabin then cleaned with a high-pressure cleaner. This way, cleaning a conventional spray booth takes about 1 hour. The necessary frequent cleaning per day results in very high cleaning costs and there is a short service life.
  • the aim of the invention is to provide a glaze spray booth in which the disadvantages mentioned are eliminated, i.e. that the cost of cleaning and the time required for it are relatively low.
  • the complete interior lining of the spray booth is made of plastic, for example based on acrylic resin with an open pore structure.
  • the inner wall parts made of plastic with an open pore structure are equipped with connections for water and air.
  • longitudinal and / or transverse lines are arranged in the lining with outlet openings uniformly distributed over their length for the supply of water and compressed air.
  • the sides of the lining facing the outer walls are provided with bores which are evenly distributed over the entire lining surface, the bores preferably having a depth which extends up to one centimeter to the inner surface of the lining. In this way it is achieved that the entire discharge can be supplied with water or compressed air evenly.
  • FIG. 1 shows a schematic front view of a spray booth according to the invention
  • FIG. 2 shows a schematic side view of the same booth
  • FIG. 3 shows a section along the line A-B in FIG. 1.
  • the glaze spray booth which is open at the front, is enclosed by the side walls 5, the rear wall 11, the top wall 7 and the bottom wall 8.
  • All walls of the cabin consist of a metal outer wall 4 and a lining 3 made of plastic with an open pore structure.
  • the side walls 5 are each divided into a lower section 5 'and an upper section 5', the lower sections 5 'in guides 6 can be pulled up.
  • the bottom wall 8 is funnel-shaped, with an opening 10 remaining in the bottom.
  • Connections 1, 2 for water and for compressed air are provided over the side walls. Water and compressed air can be introduced into the lining 3 via these connections 1, 2 for the purpose of cleaning the cabin.
  • a rotatable transport ring 9 passing through the booth from side wall to side wall, with the help of the object to be coated with glaze molding compound after pulling up the side wall sections 5 'introduced into the cabin and the object coated with glaze molding compound is removed from the cabin.
  • water is first supplied via connections 2 of the lining and then compressed air via connections 1.
  • the mixture of water and glaze molding compound flowing through the opening 10 via the side walls 5, 6 and the funnel-shaped bottom 8 can be collected in a collecting basin which is provided under the opening 10.
