DEVICE FOR THE MAGNETIC TREATMENT OF A LIQUID

The proposed device for the magnetic treatment of a liquid is intended primarily for the batch treatment of small volumes of water in domestic and industrial conditions. The treatment is carried out in a beaker by the reciprocating motion of a number of magnetised discs which cover virtually the entire cross section of the beaker. The discs are attached either to a central shaft or to the wall of an inner beaker fitted inside the main beaker and capable of sliding. When the discs are displaced along the axis, the liquid in the space between the discs is also displaced in a radial direction perpendicular to the lines of magnetic force. This cycle of flow and magnetic treatment of the liquid is maintained by providing the discs with perforations which alternate in successive discs between the central area and the circumference. Liquid is displaced in a direction perpendicular to the vertical lines of magnetic force if the magnet is arranged coaxially in the beaker in the gap between discs made of a ferromagnetic material which act as the pole ends of the magnet, or alternatively, if each disc is a magnet. Liquid is similarly displaced in a direction perpendicular to the horizontal lines of magnetic force if the magnet is arranged coaxially with the beaker in the gap between the discs, but in this case the magnet is ring-shaped with side channels to allow liquid to pass and the magnet pole is located on opposing walls of each channel. In this case, the discs are made of non-magnetic material. Le dispositif proposé de traitement magnétique d'un liquide est destiné essentiellement au traitement par lots de petits volumes d'eau dans des contextes domestiques et industriels. Le traitement est effectué dans un becher par le mouvement de va-et-vient d'un certain nombre de disques magnétisés, lesquels recouvrent virtuellement toute la section du becher. Les disques sont fixés soit à un axe central soit à la paroi d'un becher intérieur monté dans le becher principal et capable de coulisser. Lorsque les disques sont déplacés le long de l'axe, le liquide se trouvant dans l'espace entre les disques est également déplacé en sens radial perpendiculairement aux lignes de force magnétique. Ce cycle d'écoulement et de traitement magnétique du liquide est maintenu du fait des perforations dont sont dotés les disques, lesquelles alternent dans des disques successifs entre la surface centrale et la circonférence. Le liquide est déplacé dans un sens perpendiculaire aux lignes ve
