Definitions

  • the invention relates to a filter for separating ferromagnetic and / or paramagnetic impurities from thin media, in particular from waste water, ceramic slurry, glazes and similar suspensions, with a housing for the flow of the media and one or more magnetic bars arranged therein,
  • Filters of this type are used wherever ferromagnetic and paramagnetic contaminants have to be extracted from low-viscosity media, such as in the ceramic industry, in which ceramic slip and glazes have to be freed from such contaminants.
  • This also includes the chemical industry, the pharmaceutical industry, as well as the food and luxury food industry and other comparable areas of application, such as the purification of waste water and other contaminated liquid media.
  • the ferromagnetic and paramagnetic impurities can already be present in the raw material that is required for processing the respective end product, or When processing the materials, fine tools, grinding tools, screw conveyors, chutes, sieves and the like can cause abrasion.
  • This can be pure iron, iron oxides or other ferro- and paramagnetic compounds.
  • the housing has between an upper or lower material inlet and a lower or upper material outlet at least one guide tube with a magnetic rod arranged coaxially for the flow of the medium at a distance from the tube wall.
  • the housing of the filter advantageously consists of a cylindrical or polygonal jacket with an upper cover plate and a lower cover plate parallel thereto and guide tubes extending between the two cover plates.
  • the housing is closed below the guide tubes by a base plate and has an outlet or inlet connection.
  • a number of magnetic rods corresponding to the number of guide tubes protrudes from the base plate or the cover.
  • the number of guide tubes is equal to the number of magnetic bars, the magnetic bars being screwed to the base plate or to the cover.
  • a particularly simple assembly and disassembly results if the base plate, like the cover, is screwed or clamped to a lower or upper flange of the housing.
  • the magnetic rods can also be provided with additional sleeve-shaped cleaning screens made of a ferromagnetic material, such as fine iron or V2A material.
  • the sieves are most effective if they are made of a magnetic, rustproof material.
  • the magnetic material in the magnetic bars can consist of rare earth magnets or other magnetic materials. The cleaning effect is enhanced by the use of a matrix that fits in the outside diameter in the inside diameter of the guide tube and also holds fine particles of impurities.
  • the filter 1 is used to separate ferromagnetic and paramagnetic contaminants from low-viscosity media, in particular from waste water, ceramic slip, glazes and similar suspensions, and has a housing 2 for the flow of the media with magnetic bars 3 arranged therein.
  • the housing 2 consists of a cylindrical or possibly polygonal casing 4 with an upper cover plate 5 and a parallel lower cover plate 6, which are connected between an upper material inlet 7 and a lower material outlet 8 by at least one guide tube 9 in which a magnetic rod 3 is arranged coaxially at a distance from the pipe wall and leaves an annular space between itself and the pipe wall for the flow of the medium to be cleaned.
  • the guide tube 9 serves as a housing which is closed at its upper end by a cover to which the magnetic rod 3 is attached. The medium to be cleaned is introduced into the guide tube 9 from below, flows past the magnetic rod 3 and leaves the guide tube 9 through a lateral outlet nozzle.
  • the housing 2 has an upper inlet funnel 10 for the medium to be cleaned, and the two upper and lower cover plates 5, 6 each have three openings aligned with one another through three guide tubes 9 are connected to the magnetic rods 3 arranged therein.
  • the two upper and lower cover plates 5, 6 each have three openings aligned with one another through three guide tubes 9 are connected to the magnetic rods 3 arranged therein.
  • a larger or smaller number of guide tubes 9 and magnetic rods 3 projecting therein can also be present.
  • the housing 2 of the filter 1 is closed below the outlet openings of the guide tubes 9 by a base plate 11, which on the one hand closes the material outlet 8 towards the bottom, but from which the magnetic rods 3 also protrude, which are expediently screwed to the base plate 11.
  • the material outlet 8 opens into a lateral outlet connector 12 on the housing 2.
  • the housing 2 of the filter 1 can also, as shown in FIG. 4, have an upper closed cylinder with a cover 15 and a lateral inlet connection 16, which is then a closed system.
  • the inlet connector 16 can also be attached to the top of the cover 15 for an inlet from above.
  • the base plate 11 is screwed or clamped to a lower flange 13 or to an upper flange 17 of the housing 2, and the magnetic rods 3 are magnetic only in the region of the guide tubes 9.
  • the material or medium to be cleaned runs from above through the guide tubes 9 along the individual magnetic bars 3. Instead, the material or medium to be cleaned can also be guided along the magnetic bars from bottom to top if necessary.
  • the ferro- or paramagnetic parts contained in the material or medium are held on the magnetic rods 3, and the cleaned material leaves the filter either downwards through the lateral outlet connection 12 or upwards through the inlet connection 16 which then serves as an outlet connection.
  • the magnetic bars 3 can also be provided with sleeve-shaped cleaning screens 14 made of fine iron or V2A material, as shown in FIG. 3.
  • these fine iron sieves made of a magnetizable but non-rusting material, the surface of the magnetic bars 3 within the guide tubes 9 is enlarged. Since the surface of these fine iron sieves is very porous, magnetizable particles adhering to the sieves cannot be torn off even at higher flow velocities.
  • the cleaning screens 14 are simply pulled off the magnetic bars 3 and washed out and can then be put back on the magnetic bars 3.
  • the guide tubes 9 can be tubular with an internal one Matrix 18 are made of ferromagnetic material which, like the cleaning sieves 14, can be pulled out of the guide tubes 9 and cleaned.
  • the lower base plate 11 or the cover 15 with the magnetic rods 3 attached to it are removed from the housing 2.
  • the device is rinsed with water and the magnetic bars 3 are cleaned.
  • these are cleaned as described above.
  • the base plate 11 or. the cover 15 is attached to the housing 2 again.
  • This system can also be equipped with automatic cleaning.
  • the magnetic rods 3 are guided in a further guide tube which is arranged at a suitable distance from the outer guide tube 9.
  • This additional guide tube is preferably closed at one end and firmly welded to the base plate 11 or the cover 15 at the other end. When cleaning, the base plate 11 or the lid 15 then need not be loosened. Rather, the magnetic rods 3 are pulled outward from the additional guide tube, the separated impurities migrating downward on this additional inner guide tube to the base plate 11 or - in the case of a closed system - up to the cover 15.
  • the magnetic rods 3 When the magnetic rods 3 are completely pulled out of the inner guide tubes, there is no longer a magnetic field. Then the impurities separated on the additional inner guide tubes can be rinsed out of the filter housing 2.
  • the magnetic rods 3 can be extended and retracted from the closed housing 2 either by hand or by means of a pneumatic or hydraulic or an electrical control.
  • the fully automated process works as follows: The material supply to filter 1 is closed. At the same time, a valve with rinsing water is opened. At the same time, the material outlet outside the device is closed and a line for the outflowing rinse water is opened.
  • the magnetic bars 3 are pulled out of the filter housing 2 as described above, and the magnetizable contaminants are rinsed out.
