Definitions
- the present invention relates to an electric device to prevent the formation of calcareous incrustations, in apparatus containing water giving rise to the formation of incrustations of this kind, this device comprising a solenoid fed by a periodically variable current, within which solenoid there is a container in the form of a duct in which the water to be treated is contained.
- the object of this invention is to obtain the maximum efiiciency for a solenoid of specified characteristics fed by a specified current and to allow the largest possible number of lines of force to pass into the liquid to be treated.
- the device comprises a cylinder having a closed top and bottom with a pair of concentric tubular baliles extending downwardly from the top to a region close to, but spaced from the bottom to divide the upper portion of the cylinder into inner and outer chambers communicating with each other adjacent the bottom of the cylinder.
- a solenoid is mounted in the space between the two tubular baifles which is closed at its lower portion by a suitable closure member.
- a water supply duct extends upwardly through the bottom of the cylinder and has its discharge opening positioned in the upper portion of the inner chamber.
- the water will flow axially through the center of the solenoid, be reversed and flow in the opposite direction through the center of the solenoid, and then be again reversed and flow in the opposite direction about the external portion of the solenoid to a discharge opening in the outer upper portion of the cylinder.
- the Figure 1 is a diagram of a device according to the invention shown in section, and its feeding circuit.
- the Figure 2 is a section along the line 11-11 of Fig. 1.
- the device of the present invention comprises a cylinder 2 made of non-magnetic material and having a closed top la and a closed bottom lb. Extending upwardly through the bottom l b is a cylindrical duct I which is located centrally in the cylinder 2 and has a discharge opening positioned in the upper central portion of cylinder 2.
- baflies 3 Extending downwardly from the top la of cylinder 2 are a pair of concentric tubular bafiies 3 of non-magnetic material, dividing the upper portion of the interior of cylinder 2 into inner and outer chambers 6 and 1 respectively. Baflies 3 extend from the top la downwardly into close proximity to, but spaced from the bottom lb to provide a passage 5 placing the lower portions of chambers 6 and I in communication with each other.
- a tubular space is provided between the baffies 3 which is closed at the lower end by a closure wall 3a.
- a solenoid coil 4 In this space is positioned a solenoid coil 4.
- the upper end of the tubular space is accessible through an opening in the top la which is closed by a closure [5.
- Water to be treated is introduced into the apparatus through conduit I and flows upwardly as indicated by arrows 9 through the discharge opening into the upper portion of chamber 6 where its direction is reversed. From this point, the water fiows downwardly to passage 5 where its direction is again reversed to cause it to flow upwardly through chamber 1 and finally out of the cylinder through discharge outlet 8.
- the bailles 3 prevent the direct transverse flow of water from the opening at the upper end of duct l to the discharge outlet 8 and thereby increase the flow path of water through the apparatus.
- the solenoid 4 is fed by an alternating current system I2, if necessary through the medium of a suitable transformer l3 and fuses I4.
- Use may also be made of current of a frequency greater than the industrial frequency or even of pulsating or rectified current.
- the apparatus can be placed on a duct.
- the space occupied and the consumption are small. It can be used to advantage for removing lime from boiler water and for domestic purposes. It should be observed that the water accomplishes a sharp alteration of direction substantially equal to 180 when flowing from the duct to the enclosure or from the first to the second portion of said enclosure.
- the device shown is only one particular form of carrying the invention into effect. Various constructive modifications might be made therein without going beyond the scope of the present application.
- use might be made of a container of any form in place of the duct l, altering in consequence the form of the portions 6 and 7 of the enclosure.
- the outer wall of the enclosure need not necessarily be made of nonmagnetic material, although that is preferable. There might also be a larger number of changes of direction of the current of water by creating several enclosures.
- An electric device to prevent the formation of calcareous incrustations and dislodge those already existing, in apparatus containing water giving rise to the formation of incrustations of this kind comprising a cylinder of non-magnetic material with a closed top and a closed bottom, an inlet duct extending through the bottom of said cylinder up into the central portion of the cylinder and having a discharge opening positioned in the upper central portion of said cylinder for feeding said water into said cylinder, said cylinder having a water discharge outlet in the upper cylindrical wall thereof, a pair of concentric tubular baffles of different diameters surrounding the discharge opening of said duct and extending downwardly from the top of said cylinder to a region in proximity to but spaced from the bottom of the cylinder dividing the upper portion of the cylinder into concentric inner and outer chambers communicating with each other at the lower portion of the cylinder to prevent direct flow of water from the discharge or said inlet duct to the discharge outlet transversely of the cylinder, said bariers providing a tubular space between
