  • magnetism in the magnetic layers 301, 303 in FIG. 5 which are separated by the ceramic layer (s) 302 is provided by irregularly and differently shaped magnet pieces 90 which are disbursed throughout the magnetic layers 301 and 303 together with magnetite pieces 92.
  • FIGS. 6, 7 and 8 are also vertical cross- sectional views of three additional preferred embodiments of magnetic sections MS of a fluid purifier.
  • the embodiments in FIGS. 6-8 differ from those shown in FIGS. 1 and 5 in that the components in the magnetic section are not layered in FIGS. 6-8. Instead, the various components are distributed relatively uniformly over the height of the chambers 94 and the ceramic layers are eliminated. Instead the ceramic is present in the form of a coating 96 on one or more of the components.
  • the chamber 94 contains relatively uniformly mixed but differently shaped and irregular magnet pieces 90 as in FIG. 5, and magnetite pieces 92. However, the magnetite pieces in FIG. 6 have the ceramic coating 96 coated thereon.
  • Coating the magnetite pieces 92 in FIG. 6 and magnetic pieces 94 in FIG. 7 with the ceramic coating 96 has the advantage that it protects the pieces against rust. Such ceramic coating also places the ceramic which has somewhat of a catalytic effect closer to the magnetic action.
  • the magnet pieces 90 are preferably of different and irregular shape to prevent them from attracting and attaching to each other to the extent that they might stick together and block the flow of water. Because they are of different shape and are irregular, even if they do stick together, there are numerous pores and voids between the combined structure to permit the passage of water through the agglomerated structure and in close proximity to the magnetic fields of the respective pieces for enhanced magnetic treatment.
  • magnetite pieces 92 are again coated with a ceramic coating 96 as in FIG. 6, but the magnet pieces 90 have been replaced at the various levels with annular solid magnetics 40- 5, 40-6 and 40-7 similar to the embodiment shown in FIG. 1.
  • FIGS. 6-8 essentially eliminate the need for discrete levels or layers of treatment materials in the magnetic section MS. This facilitates both the ease of assembly as well as replacement of materials .
  • FIGS. 5-8 are depicted as annular in form as in FIGS. 1 and 4A, it will be appreciated that they may also take the center form shown in FIG. 4B.

Abstract

L'invention concerne un purificateur de fluide qui comprend un filtre pourvu d'une chambre à section transversale formée soit entre une paroi intérieure et une paroi extérieure, soit dans la paroi intérieure. Une couche céramique de particules céramiques granulaires et au moins une paire de couches magnétiques comprenant chacune un aimant annulaire et des pièces de magnétite sont disposées au-dessus ou au-dessous de la couche céramique de la chambre. Les aimants annulaires sont arrangés de manière que les mêmes polarités des aimants annulaires adjacents se fassent face et que la direction des lignes magnétiques de force soit parallèle à la direction d'écoulement du fluide. Les molécules de fluide sont activées lorsqu'elles traversent le champ magnétique produit par les couches magnétiques d'aimants annulaires et les pièces de magnétite qui sont magnétisées par les aimants annulaires. Dans d'autres mode des réalisation, les aimants peuvent être des pièces magnétiques façonnées différemment et irrégulièrement, les pièces de magnétite peuvent également être présentes et les pièces magnétiques et/ou les pièces de magnétite peuvent être recouvertes de la couche céramique.
