DEVICE WITH PERMANENT MAGNETS FOR MAGNETIC TREATMENT OF FLUIDS CIRCULATED THROUGH PIPES

The invention relates to a device with permanent magnets meant to treat, at the pipe level, the circulated fluids. According to the invention, the said device comprises some magnetic circuit-modules, arranged along a pipe (1) having circular section in transversal plane, separated by means of some non-magnetic end and intermediary spacers (2 and 3), there being carried out a heteropolar assembly by alternating the magnetizing sense in the circular direction in the successive modules, each module comprising, in a star-like location, some prismatic permanent magnets (4), with trapezoidal cross-section and circular magnetizing direction, their sides delimiting an equal number of useful entrefers (delta), with transversal section, also trapezoidal, wherethrough there is axially circulated a fluid (t) to be treated, so that, by a local correlation between the magnetomotive force and the magnetic force failure, there is provided a relatively constant value of the magnetic induction in the entrefer (delta), the radially and circularly correct positioning of each magnet (4) being provided, on the one hand, by an exterior non-magnetic bush (5) provided with some recesses at the inner side, for guiding the large base of each magnet (4) and, on the other hand, by a central non-magnetic axle (6), with recesses at the exterior side, for guiding the small base of each magnet (4); the circular position correspondence between the modules and relative to the end spacers (3), being achieved by some intermediary pinss (7), and the axial rigidity of the modules is ensured with some special end screws (8), at the extremities of the central non-magnetic axle (6). Invenţia se referă la un dispozitiv cu magneţipermanenţi, destinat tratării, la nivelul conductelor, a fluidelor vehiculate. Dispozitivul conform invenţiei cuprinde ni?te module-circuit magnetic, dispuse în lungul unei conducte (1), având,în plan transversal, secţiune circulară, separate între ele cu ajutorul unor distanţoare (2 ?i 3) intermediare ?i de capăt, nemagnetice, realizând un ansamblu heteropolar, prin alternarea sensului de magnetizare pe direcţia circulară la modulele succesive, fiecare modul conţinând într-o amplasare stelată, ni?te magneţi (4) permanenţi prismatici, cu secţiune transversală trapezoidală ?i direcţie de magnetizare circulară, feţele lor laterale delimitând un număr egal deîntrefieruri utile (delta), cu secţiune transversală, de asemenea trapezoidală, prin care este vehiculat axial un fluid
