  • the invention relates to a filter, in particular usable in a paint recycling system for the recovery of raw paint and solvent and / or water from the overspray during wet painting.
  • Stainless steel can exist. Such filtration chambers have proven themselves.
  • the object of the invention is to provide an even more effective filter that is easy to manufacture and takes up less space.
  • the filter according to the invention shown in a longitudinal section is tubular and essentially consists of the outer tube 1, preferably made of metal, for example stainless steel, and the membrane tube 2 arranged therein as a filter insert, with a radial distance between the membrane tube 2 and the outer tube 1 Form of a cylindrical annulus 3 is provided.
  • the inner diameter of the outer tube 1 is for example between .2.5 .... and .45 .... mm and the thickness of the cylinder annulus 3 between .Q.,. 5 .. and .. A u ... mm.
  • the outer tube 1 On the end faces 4 and 5, the outer tube 1 has a flange ring 6 protruding outward at right angles, against which an annular one

  • the cover disk 7 has a central hole 10, the diameter of which is smaller than the inner diameter of the outer tube 1 and, for example, is only about one third as large as the inner diameter of the outer tube 1.
  • At the hole 10 there is an outwardly projecting connecting pipe socket 11 , whose inside diameter corresponds to the diameter of the hole 10.
  • the pipe socket 11 serves to connect a feed or discharge line (not shown) for the overspray mixture and has, for example, an internal thread 12 for the connection of these lines.

  • the membrane tube 2 is self-supporting and is preferably only mounted on the end face in the outer tube.
  • Self-supporting in the sense of the invention means that the membrane tube 2 is so rigid or stiff that it can withstand the excess pressures which occur in the interior 13 during filtering, so that the annular space 3 between the outer tube 1 and the membrane tube 2 is not significantly reduced is, or the membrane tube 2 only insignificantly expands.
  • This rigidity of the membrane tube 2 is achieved by a special structure which is described below and which is known as synergistic effect ensures optimal filtration, in particular of a paint overspray mixture, which could not previously be achieved.

  • the membrane tube 2 according to the invention has a rigidity which is sufficient to withstand filtration pressures of, for example, 1 to 70 bar. It can and should follow the invention a certain stretch take place, which ensures that optimal pore sizes in the layers 17, 18, 19 and 20 are set for the filtration of a certain product, ie that according to the invention, the filtration result can be regulated by adjusting the pressure .
  • the membrane tube 2 is supported on both sides by a funnel connection 21, preferably made of stainless steel.
  • a funnel neck 21 consists of a cylinder part 22 and a funnel part 23, the cylinder part 22 being mounted centrally in the pipe socket 11 and the funnel part 23 projecting axially a little into the interior 13 of the membrane tube 2.
  • a plastic ring 24, e.g. a teflon ring is provided to seal the cylinder part 22 to the inner wall of the pipe socket 11, so that a gusset gap 26 remains between the funnel part 23 and the membrane tube 2.

  • This washer 29 is connected to the end face of the membrane tube 2 and the outer surface of the funnel part 23, preferably glued, so that a sealing closure results.
  • An annular space 30 is provided between the annular disk 29 and the cover ring 7, so that the annular disk 29 is arranged at a distance from the cover ring 7.
  • the paint overspray mixture is passed, for example, in the direction of arrow 31 into the interior 13 of the membrane tube 2.
  • the permeate migrates in the direction of the arrows 32 into the cylindrical annulus 3 through the wall of the membrane tube 2, while the retentate is passed out of the filter in the direction of the arrow 33.
  • membrane tubes 2 can also be arranged at a distance from one another, all in one
  • Membrane tubes with a spacing outer tube are used in stock, with corresponding bearing devices in the outer tube and lines to the end faces of the outer tube being provided.
  • the filter according to the invention can be used for large, fine, ultra and hyperfiltration as well as for reverse osmosis and in particular also for solvent-containing overspray mixtures.

Abstract

Le filtre sert à récupérer la laque brute et les solvants et/ou l'eau provenant de l'excédent de peinture projetée lors du laquage par voie humide, et est caractérisé par une membrane tubulaire (2) multicouche (17, 18, 19, 20) logée dans un tube extérieur (1) de préférence en métal et utilisée comme garniture de filtre, un écartement radial sous forme d'un espace annulaire cylindrique (3) étant prévu entre la membrane tubulaire (2) et le tube extérieur (1).
