Definitions
- 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
- Cover plate 7 is set.
- the cover disk 7 is fastened to the flange ring 6, for example by screw connections 8, an elastic sealing ring 9 preferably being arranged between the flange ring 6 and the cover disk 7.
- the attachment of the cover plate 7 with the flange 6 can also in other known ways, for. B. by welding, soldering, gluing or the like. All-over homogeneous attachment.
- 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.
- a plurality of drainage openings 14 are provided, which are equipped with pipe sockets 15, on which connecting pipelines can be arranged in order to discharge a permeate of the overspray mixture.
- 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 initially has a rigid jacket tube 17 made of plastic, e.g. made of epoxy resin with pores 16.
- the pores 16 are in the size range from 1 to 0.01 ⁇ m.
- the jacket tube 17 is constructed from an epoxy resin-impregnated fabric, its thickness being between 1 and 3 mm.
- the fabric of the fabric layer 18 has e.g. a mesh size of 0.1 to 0.001 mm and e.g. a thread thickness of 0.1 to 2 mm and is preferably from 0.5 to 1 mm thick.
- the inner surface of the fabric layer 18 is coated with an epoxy resin layer 19, which preferably has or develops pores in the order of magnitude between 1 and 0.001 ⁇ m.
- the thickness of the epoxy resin layer 19 is e.g. between, 0.1 and 1 mm.
- the thickness of the polyurethane layer 20 is preferably between 0.2 and 0.05 mm.
- a second epoxy resin layer 19 can also be applied.
- the passages or pores of the layers 19, 20 can form during the action of the liquid to be filtered by e.g. Loosening of the structure and / or ion conduction can occur.
- 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 gusset gap 26 is filled in a form-fitting manner with an epoxy resin ring 27 which is part of an epoxy resin washer 29 which is connected frontally to the membrane tube 2 and is supported on the outer jacket of the funnel part 23.
- 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.
- the filter can be used in particular for pressures between 0 and 70 bar in the temperature range 0-40 ° C. In the case of reverse osmosis, pressures up to 100 bar can even be applied.
