DESCRIPTION:
BRIEF SUMMARY
The invention is directed to an arrangement for water treatment with a magnetic field generated by an electromagnet wherein an electromagnet with at least one excitation coil can be applied to the external surface of a pipe carrying water.
It is known to direct potable water in pipes carrying water in such a way through the magnetic lines of force of a solenoid in order to avoid calcareous sediments or furring, so that said water repeatedly intersects the lines of force of said solenoid. The magnetic field through which the potable water is directed distorts or influences the water molecules which are composed of one oxygen and two hydrogen atoms. Because of the influence of the magnet the electron from the respective inner electron circuit is urged into the outer circuit. Viewed physically the atomic lattice is destroyed by this action. Pieces of lime are split into microfine particles, they are changed as far as their crystalline structure is concerned and thus they lose the property to deposit themselves as sediment. This means that the lime shares are held in suspension and are eliminated together with the flowing water.
A whole series of arrangements for appliances are known which build up a magnetic field in pipes carrying water and thus appropriately affect the passing potable water. These are complicated structures as a rule, which have to be separately built into the water pipeline network or however the excitation coils embrace the pipes carrying water, which naturally also leads to expensive manipulation in the water supply system.
It is also known to attach a permanent magnet at the external side of a pipe. The use of a permanent magnet for such an arrangement is inappropriate, because the danger of a line blockage exists due to the field of magnetic force always remaining constant, particularly since iron particles carried in the water are attracted to the region of the applied permanent magnet. This danger of clogging can only be avoided by arranging an electromagnet with an excitation coil and thus with the possibility of connecting same to a source of pulsating direct current. Furthermore the effect of this permanent magnet is impaired since the contact surface of same extends tangentially to the surface of the pipe.
The present invention has set itself the task to create an arrangement of the previously described type, which enables to exploit the advantages of an optimum effect of magnetic fields upon the flowing water without any reconstruction in the water supply system being required.
The arrangement proposed for solving the problem is characterized by the electromagnet comprising a U- or E-shaped iron core, whose freely projecting legs can be pressed against the pipe consecutively across its longitudinal extent, wherein the free ends of the legs are matched or are matchable to the surface curvature of the pipe.
Thus a magnetic field of force can be built up at any random point of the pipe carrying water by means of the measures in the invention, without that extensive disassembly or installation work has to be performed at the pipelines themselves. Therefore an electromagnet can be directly applied to the surface of a pipe carrying water in accordance with the invention, wherein tests have shown that the effect of such an arrangement is an optimum one. Because of the feature of the invention that the free ends of the legs of the iron core are matched or are matchable to the surface curvature of the pipe, it is always assured that no air gap is formed between the legs of the iron core and the pipe carrying water, so that no weakening of the magnetic field of force occurs. Only by means of these additional measures it became possible to perform a simple application of an electromagnet to a pipe carrying water.
Favorable acquisition and installation costs made possible by the inventive arrangement are also worth mentioning, since the water supply system does not have to be interrupted during the installation of our arrangement.
