Abstract

PURPOSE:To expose efficiently fluid to a magnetic field by forming an inside flow passage consisting of a central member of a ferromagnetic material on the inside of a cylindrical magnet and an outside flow passage consisting of an outside pipe of a ferromagnetic material on the outside of the cylindrical magnet so that the line of magnetic induction crosses the inside and outside flow passages. CONSTITUTION:Water to be treated introduced into a connecting port 19 passes through the aperture 15 of a pipeline guide 13 and through a notched surface 17 and flows into a mixing chamber contiguous to the aperture 15. A part of the treated water flows into an outside flow passage 25 and the rest flows into an inside flow passage 25 through the inside surface 24 at the end part of an outside jacket 3. The water flows respectively in the longitudinal direction of the passages 25, 26 and is confluent in a mixing chamber 23, from which the mixed water flows to the port 19. Since an outside pipe 1 and a central member 21 are ferromagnetic, the line of magnetic induction generated from a magnet 4 goes toward the outside and inside in a radial direction and arrives at the pipe 1 and the member 21. Said line of magnetic induction crosses the entire toric sectional surface of the inside passage 25 and the outside passage 26 thus exposing the flowing water to the magnetic field.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for treating water in order to reduce rusting of iron-based piping materials and to reduce the adhesion of water scale, especially when water passes through a cylindrical flow path. This relates to a device that is exposed to a magnetic field.

Pipes, boilers, etc. that form piping equipment in factories, offices, etc.
A problem with air conditioning equipment, etc. is a reduction in the flow path area due to rusting of iron-based materials, and in severe cases, water leakage due to holes in the material, water scale, hot water scale, etc. adhering to the inner surface. This results in a decrease in flow path area, a decrease in thermal efficiency, etc. In order to prevent this, it is necessary to condition the water with chemicals or with a magnetic water treatment device.

One such magnetic water treatment device is described in US Patent No. A951,807. It has longitudinally spaced magnetic poles housed in a non-magnetic jacket and includes an elongated magnet positioned concentrically within a galvanized outer casing made of magnetic material. The magnet housed in the jacket is centered by a pair of stepped collars affixed thereto, and these collars are centered by a pair of outwardly opening insert pieces. However, it is well known that this type of magnetic water treatment device is capable of easily removing calcium or other minerals present in the running water from the device by blowing them off or washing them off. By creating a soft slurry that can be used to form a slurry, it is possible to prevent scale from accumulating.

In order to realize this prevention effect more efficiently, the present invention disposes a central member made of a ferromagnetic material inside a cylindrical permanent magnet (hereinafter referred to as a cylindrical magnet) to form an inner flow path,
In addition, an outer tube made of ferromagnetic material is placed outside the cylindrical magnet to form an outer flow path, and the magnetic flux lines generated by the cylindrical magnet are made to cross this inner and outer flow path, thereby maximizing the magnetic field of the flowing water. It is an object of the present invention to provide a magnetic water treatment unit device having a structure that exposes the water to water.

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.

Outer jacket 3 made of non-magnetic material such as copper or brass
A collar 5 made of a non-magnetic material such as plastic or a ferromagnetic material such as i- is sandwiched in the cylindrical space formed by the inner jacket 6 and the magnetic poles spaced apart in the longitudinal direction, that is, N and S poles. Cylindrical magnets 4 having poles are housed with the same poles facing each other. That is, the cylindrical magnets 4 are arranged so that the S poles and the N poles alternately face each other, and both ends of the magnet array are fixed to the outer jacket 3 and the inner jacket 6 by means of the part 7 with a soldering pad or the like. The number of cylindrical magnets 4 to be arranged is determined based on the relationship between the flow rate to be treated, the thickness of the flow path, the strength of the magnets, etc., but it is desirable to arrange at least two or more. Next, iron
A central member 21 made of a ferromagnetic material such as steel and having a surface treatment such as galvanizing on its outer surface and having an outer diameter smaller than the inner diameter of the inner jacket B is penetrated into the center of the inner jacket 6. The annular inner flow passages 2 and 5 are formed between the inner jacket 6 and the inner jacket 6. Further, the outer tube 1 is made of a ferromagnetic material such as iron or steel and has an inner diameter larger than the outer diameter of the outer jacket 3, the surface of which has been subjected to a surface treatment such as galvanizing.
are concentrically covered with the outer jacket B to form an annular outer flow path 26 between the outer jacket 5 and the outer jacket 5. Furthermore, the pipe guide 13 is made of a non-magnetic material and has a cylindrical wall part forming an opening 15 and a cutout surface 17 which is a part of the cylindrical bottom part, which fits into both ends of the outer jacket 3, respectively. A female thread 16 is provided at the bottom of the cylinder, and the male thread 22 at both ends of the center member 21 are fastened to the thread 16. Furthermore, the stepped portion 14 of the cylindrical bottom of the pipe guide 13 is attached to the end portion 8.10 of the outer jacket 3 so that the positions of the cutout surfaces 17 of the pipe guide 13 are in opposite directions to each other. A set screw 12 made of brass or stainless steel or the like is screwed into the stepped portion 14 of the conduit guide 13, and is fitted inside and passes through a hole 9.11 in the end 8.10 of the outer jacket 3. Dress up. Furthermore, it fits into the cylindrical wall portions of the conduit guides 13 on both sides, and the connection port 19 at the outer end
It has a pipe opening 20 connected to the outer pipe 1, and has fittings 18 made of a material that does not rust in water, such as brass, stainless steel, or plastic, on both sides of the outer pipe 1 (threaded into the screw 2). urge

In the apparatus of the embodiment described above, the water to be treated introduced into the connection port 19 passes through the opening 15 of the pipe guide 13 and the cutout surface 17, and flows into the mixing chamber 23 connected to the opening 15. A part of this water to be treated flows into the outer channel 26, and the remainder flows into the inner channel 25 through the inner surface 24 of the end portion of the outer jacket 3 and flows in the longitudinal direction of the channels 25 and 26, respectively. They join together in the mixing chamber 23 and reach the other connection port 19 as one.

Since the outer tube 1 and the central member 21 are ferromagnetic, the magnetic flux lines generated by the magnet 4 travel inward and outward in the radial direction and reach the outer tube 1 and the central member 21. Therefore, the magnetic flux lines generated by the magnet 4 do not cross the entire annular cross section of the inner channel 25 and the outer channel 26, and the water flowing in both channels can be efficiently exposed to the magnetic field. By wrapping the magnet 4 in the outer jacket 3 and inner jacket Δ made of non-magnetic materials, it is possible to prevent the magnetic field from short-circuiting before passing through the inner and outer channels.

According to the present invention, for example, US Pat.
Compared to conventional magnetic water treatment devices such as those described in US Pat. No. 51.807, the treatment efficiency can be significantly improved. In other words, the required number of cylindrical magnets are covered with inner and outer jackets, a ferromagnetic center member is passed through the inner surface of the inner jacket to form an inner flow path, and an outer tube of ferromagnetic material is placed on the outside of the outer jacket. The structure is such that the lines of magnetic force emitted by the magnet cross the inner and outer flow channels, so the magnetic field processing area is extremely small and the fluid can be efficiently exposed to the magnetic field. It is. The magnets used in the present invention are ferrite magnets, which are highly mass-producible and economical, and are still sufficiently effective.Also, the method of manufacturing cylindrical magnets is similar to that used in the conventional device. Ferrite magnets are preferable to expensive alnico magnets, and from this point of view, they are compact compared to the processing flow rate.
The present invention can provide an economical water treatment device.
