Description

DETAILED DESCRIPTION OF THE INVENTION The present invention reduces the occurrence of rust on iron-based piping materials, and reduces the adhesion of scale to the inner surfaces of iron-based piping materials and iron-based materials that come into contact with fluids in boilers, air-conditioning equipment, etc. The present invention relates to a device for treating water, particularly a device for treating water by exposing the water to a magnetic field as it passes through a cylindrical channel.

The problem with pipes, boilers, air-conditioning equipment, etc. that form the piping equipment of factories, offices, etc. is the reduction of the flow path area due to rusting of iron-based materials. Water leakage due to holes in the tube, a decrease in flow path area due to the adhesion of water scale, hot water scale, etc. to the inner surface, and a decrease in thermal efficiency, etc. occur. In order to prevent this, it is necessary to condition the drain water with chemicals or with a magnetic water treatment device.

One such magnetic water treatment device is described in US Pat. No. 1951.807. It has longitudinally spaced magnetic poles housed in a non-extrusive jacket and has elongated magnets 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 fixed thereto, and the stepped forces 2- are centered by a pair of outwardly opening insert pieces. However, this type of magnetic water treatment device is well known in that calcium or other minerals present in the flowing water can be easily removed from the device by blowing it off or washing it away. By creating a soft slurry like this, it is possible to prevent scale from accumulating.

An object of the present invention is to provide a magnetic water treatment device having a structure that exposes running water to the magnetic field to the maximum extent in order to realize this prevention effect more efficiently.

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIGS.

A collar 5 made of non-magnetic material such as plastic is placed inside a cylindrical jacket 5 made of non-magnetic material such as copper or brass.
A plurality of cylindrical magnets 4 having a plurality of magnetic poles are arranged and housed in the axial direction at intervals in the circumferential direction on the outer peripheral surface of the magnet. Both ends of this magnet array are fixed within the cylindrical jacket 3 by soldering parts 6 or the like, and further sealed to prevent the cylindrical magnets 4 from coming into direct contact with water. Furthermore, this cylinder 8
The number of stones 4 to be arranged is determined based on the relationship between the flow rate to be treated, the thickness of the channel, the strength of the magnet, etc., but it is desirable to arrange at least two stones.

The outer tube 1 is made of a ferromagnetic material such as iron or steel and has a surface treatment such as galvanizing, and has an inner diameter smaller than the outer diameter of the cylindrical jacket 3. '5vC are concentrically placed over each other to form an annular flow path 15 between the cylindrical jacket 5 and the cylindrical jacket 5.

Furthermore, both ends of the cylindrical jacket 3 are extended beyond the soldered ends 6 of the magnet array to form an open tubular outer end 9.10.

The opening 13 that fits into the outer diameter of the outer end 9.10 and connects to the pipe connection screw +4VC is provided with a port 13, and is further screwed into the male thread 2 provided at both ends of the outer tube 1. A fitting 11 made of a material that does not rust when exposed to water, such as brass or stainless steel or FCIA plastic, is fitted onto the outer end 9.10, and has a female threaded portion. 2 is screwed into the female threaded portion and fastened to both ends of the outer tube 1. Furthermore, notches 7.8 are provided at both ends of the tubular outer end 9.10 of the cylindrical jacket 3, so that the water to be treated passes through the opening 14 of the outer end 9 on one side. The fluid passes through the notch 7 to reach the annular flow path 15, and flows through the notch 8 at the outer end 1° on the other side and through the opening 16.

FIG. 3 is a cross-sectional view taken along line B--B in FIG. 1. In this embodiment, the magnetic poles on the outer periphery of the cylindrical magnet 4 have a total of six poles, alternating N and S poles, radially from the center. FIG. 4 is a sectional view taken along the line CC in FIG. 1, and the arrangement of the magnetic poles is the same as in FIG. 3. That is, in this embodiment, the same poles are arranged in a straight line.

FIG. 5 is a cross-sectional view taken along the line C-0 in FIG. 1 showing another embodiment. 5 are arranged alternately with adjacent cylindrical magnets 4 in between.
The magnetic poles are arranged in different directions in the circumferential direction. It should be noted that other magnetic pole arrangements, such as adjacent cylindrical magnets 4
It is also possible to adopt an arbitrary arrangement, such as arranging the magnetic poles of the foreign objects on a straight line.

The device of the invention comprises a cylindrical jacket 6 made of non-magnetic material.
By wrapping the cylindrical magnet 4 with the collar 5, a short circuit is prevented before the magnetic field crosses the flow path 15.

As described above, according to the present invention, the N
The magnetic flux lines emitted radially from the poles and south poles cross the flow path at right angles to the flow direction of the processing fluid and reach the outer tube made of ferromagnetic material, and the notches in the jacket are 180 degrees apart, making it difficult to cross the flow path. Due to the synergistic effect that the flowing fluid becomes a diagonal flow,
Since the processing fluid commonly passes through lines of magnetic flux having different directions, the fluid can be efficiently processed magnetically.
