Abstract:
A permanent magnetic water treating device comprising:a tubular housing having disc-shaped ring magnets and magnetizable spacer discs located therein, said housing having a longitudinal axis, said ring magnets and said spacer discs extending coaxially to said longitudinal axis, said housing having a first connecting piece at one end thereof and a second connecting piece at an opposite end thereof, said housing having a means therein for causing a continuous spiral motion of the water passing through said housing; and an inner tube positioned in said housing coaxially to said longitudinal axis, said inner tube spaced at an distance from an inner wall of said housing, said inner tube having a first end connected in liquid-tight relationship to said first connecting piece, said inner tube having a second end connected in liquid-tight relationship to said second connecting piece, said inner tube suitable for allowing a flow of the water to be treated to pass therethrough, said ring magnets and said spacer discs being installed in a liquid-free space between said inner tube and said inner wall of said housing, said ring magnets and said spacer discs alternating in location along said longitudinal axis, said tubular housing being of a non-magnetizable material, said inner tube being of a magnetizable rustproof material, said first and second connecting pieces each being tubular and of a magnetizable rustproof material, said first and second connecting pieces extending from said ends of said inner tube so as to form a single piece therewith, at least one of said ring magnets being identical to each other, one of said ring magnets being positioned after one of said spacer discs at said first end of said inner tube such that a south pole of said ring magnet faces said first end, said first end being a water inlet, each of the other of said ring magnets being positioned after pairs of said spacer discs, said ring magnets comprising three ring magnets arranged with a polarity inverted sequentially between one another, said ring magnets further comprising at least two twinned magnets having polarities inverted with respect to an adjacent ring magnet of said three ring magnets and with respect to each other, each magnet of said twinned magnets contacting each other with opposite poles such that a south pole faces said second end of said inner tube, said spacer discs comprising an end spacer disc which is thicker than the other of said spacer discs, said end spacer disc positioned against the south pole of said twinned magnets adjacent said second end of said inner tube, said ring magnets and said spacer discs being tightly enclosed in immovable relation within said housing by a pair of sleeves screwed respectively on said first and second connecting pieces, said inner tube having a strip therein formed of a magnetizable rustproof metal having a width corresponding to an inner diameter of said inner tube, said strip being wound into a helix having one to three turns, said strip having end sections extending respectively into said first and second connecting pieces, said end sections being of non-helix form and diametrically opposed to each other.
