Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is useful for, for example, removing red rust, scale, etc. formed in piping, and for preventing red rust, scale, etc. forming in piping. The present invention relates to a water magnetic treatment device used.

Conventional technology When pipes for water supply and hot water supply in buildings, etc. are used for many years, the inner walls of the pipes corrode and rust occurs, and impurities in the water settle, reducing the inner diameter of the pipes and reducing water pressure. Not only that, so-called red water occurs, and eventually water leaks and water outages occur.

Conventionally used construction methods to prevent these problems include a method in which compressed air is used to blow silica sand, etc. to scrape away the rust, and then a lining treatment is performed with epoxy resin, etc., and a method in which rust is removed by chemical means. There are construction methods that involve lining the water after the water has been removed, but these methods all have problems such as requiring long-term water outages and being expensive.

In recent years, magnets have been installed in water supply and hot water equipment, and by passing the supplied water between the magnetic poles, the water is treated magnetically, and this water is passed through the pipes to remove red rust that has formed on the inner walls of the pipes. The magnetic treatment method, which prevents the formation of red rust and the deposition of impurities, is being adopted because it allows construction to be carried out without water outages for a long period of time, does not cause problems with water quality, and is inexpensive.

Although there is no final academic opinion on why passing magnetically treated water through pipes removes red rust from the inner walls of pipes, or prevents the occurrence and deposition of red rust, etc. , impurities contained in water by passing it through a magnetic field,
In other words, electrolytes that exist in the form of ions, non-electrolytes that exist in the form of molecules, microdispersed solid particles, and dissolved gases are not subjected to magnetic or electrical action or undergo physical or chemical changes. It is thought that

Various devices have been considered as devices for magnetically treating water. The present inventor also previously proposed a water magnetic treatment device. (Utility Application No. 61-142756) Magnetic treatment of water is useful for removing and preventing scale, so it is also used in heat exchangers, boilers, and hot spring water supply.

Problems to be Solved by the Invention However, in the previously proposed magnetic processing device, each magnetic processing assembly housed in the housing must be manufactured according to the size of the inner surface of the housing, which is inconvenient. However, there were problems such as the efficiency of the magnetic treatment of water was not sufficient.

The present invention solves the above problems.

Means for Solving the Problems In order to solve the above problems, the present invention provides the following water magnetic treatment apparatus.

A magnet laminate consisting of alternating layers of magnetic pole pieces and magnets each having a through hole or notch on the periphery is placed inside a porous cylindrical body. An end plate having a large outer diameter and having a through hole for allowing water to flow inside the porous cylindrical body is provided, and an end plate is provided on the outer periphery of the porous cylindrical body to prevent the flow of water.
Alternatively, a magnetic processing device characterized in that two or more blocking bodies are provided to constitute a magnetic processing assembly, and the magnetic processing assembly is housed in a housing provided with a water inlet and a water outlet.

Various types of magnets can be used, such as ferrite-based magnets and alloy-based magnets, but ferrite-based magnets are preferred for economical reasons. Since ferrite magnets have weak mechanical strength and are easily chipped, it is preferable to cover and reinforce them with non-magnetic stainless steel, synthetic resin, or the like.

Magnetic pole pieces are used to collect lines of magnetic force and create a strong magnetic field between adjacent magnetic pole pieces, and are made of magnetic stainless steel, soft iron, silicon steel, etc. Further, the through hole or notch provided on the periphery of the magnetic pole piece is for allowing the water to be treated to flow through it and for efficiently treating it, and may have any shape. The shape of the hole is circular,
Oval, polygonal, 〓, 〓, etc. are used as the shape of the notch, and fan shape, 〓, etc. are used.

Preferably, one pole piece is provided with both a through hole and a notch. By partially shifting the positions of the through holes or notches of adjacent magnetic pole pieces, it is possible to sufficiently apply the action of the magnetic field to the water without increasing pressure loss.

The porous cylindrical body is a cylindrical body provided with a large number of through holes, and its cylindrical shape is convenient for handling. The holes provided in the cylindrical body can be obtained by various methods. For example, it can be obtained by forming a cylindrical body with a net or by punching holes.

Alternatively, the holes may be formed by forming tongues 26 as shown in FIG. In this case, the tongue piece 26
serves to guide the flow of water, so by orienting the tongues 26 in an appropriate direction, the flow of water can be regulated so that magnetic processing can be performed satisfactorily.

As the material for the porous cylindrical body, non-magnetic stainless steel, synthetic resin, etc. are used.

End plates are provided at opposite ends of the porous tube to support the magnetic processing assembly within the housing and define a chamber between the housing and the porous tube.

The blocking plate separates a chamber between the housing and the porous cylindrical body, regulates the flow of water, and enables sufficient magnetic processing.

Next, specific examples of the present invention will be explained with reference to the drawings.

FIG. 1 shows a magnetic processing device with a housing 1 partially cut away.

The housing 1 is constructed by attaching lids 4 and 4' having pipe connection ports 3 and 3' to both open ends of a cylindrical body 2 with open ends using fixing means such as bolts and nuts. 5 is a flange used for attachment.

A magnetic processing assembly 6 is housed within the housing 1 .

The magnetic processing assembly 6 includes end plates 7, 7', a plurality of blocking plates 8, a perforated cylinder 9, and a magnet stack 10. (See FIG. 2) The end plates 7, 7' have a circular shape, the diameter of which is larger than that of the perforated cylinder 9 and equal to the inner diameter of the cylinder 2 of the housing 1. Further, as shown in FIG. 3, a circular groove 11 into which the end of the porous cylindrical body 9 fits is provided, and a shaft hole 13 through which a threaded portion 12 is inserted is provided at the center of the groove. A plurality of through holes 14 for introducing water into the porous cylindrical body 9 are provided on the virtual circle.
is provided.

The porous cylindrical body 9 is made of a non-magnetic stainless steel mesh, and the mesh serves as holes.

The magnetic pole piece 15 is made of magnetic stainless steel, and, as shown in FIG. 4, has a square shaft hole 16 at its center, and a through hole 17 and a notch 18 at its periphery.

The magnet 19 is a ferrite magnet having a shaft hole 20 in the center.

Pole piece 15 and magnet 19 are assembled into magnet stack 10 by shaft 21 . The shaft 21 has a square cross section, and both ends thereof are screwed. The magnet laminate 10 is obtained by alternately attaching magnetic pole pieces 15 and magnets 19 to a shaft 21, and screwing a nut into a threaded portion of the shaft 21 to assemble the magnet. If the magnetic poles of the magnet 19 are arranged as shown in FIG. 2, a strong magnetic field can be obtained.

Adjacent magnetic pole pieces 15 are shifted by 90 degrees so that their notches 18 do not overlap, taking advantage of the fact that the square shaft hole 16 and the shaft 21 have a square cross section.

The magnetic processing assembly 6 inserts the magnet laminate 10 into a porous cylindrical body 9 fitted with a plurality of blocking plates 8, and inserts the end plates 7, 7' through the shaft holes 13, 13' so that the threaded portion 12 of the shaft 21 is inserted. Also, the groove 11 is connected to the porous cylindrical body 9 so that
This can be obtained by fitting the screw into the end of the screw and screwing a nut onto the threaded portion 12.

The water to be treated flowing in from the pipe connection port 3 passes through the through hole 14 of the end plate 7 and enters in front of the magnetic pole piece 15 . This water to be treated is passed through the through hole 17 and notch 18 of the magnetic pole piece 15.
It flows into the front of the next magnetic pole piece 15 through the magnetic pole piece 15, and also flows to the outer circumference of the magnetic pole piece 15. The water to be treated that has circulated to the outer periphery collides with the porous cylindrical body 9 and becomes a turbulent flow.
These things occur between each magnetic pole piece 15, and the water to be treated is treated by the magnetic field generated between adjacent magnetic pole pieces 15.

The water to be treated that exits from the porous cylindrical body 9 to the housing side returns to the porous cylindrical body 9 and undergoes magnetic treatment.
The blocking plate 8 ensures this return.

Therefore, since the water to be treated is repeatedly treated under a strong magnetic field, sufficiently magnetically treated water can be obtained.

FIG. 5 shows another embodiment of the pole piece, in which three fan-shaped cutouts 18' are provided at 120° intervals, and three through holes 17' are provided between them. In addition, the blade portion 22 is used to give swirl to the water.
You can also give it a twist.

FIG. 9 shows another embodiment of the invention in which a plurality of magnetic processing assemblies 6, 6' are housed in series within a housing.

FIG. 10 shows another embodiment of the present invention, in which the magnetic processing assembly 6 is housed in a cylindrical body 24 having flanges at both open ends and having pipe connection ports 23, 23'. The lids 25, 25' are bolts,
It is attached with a nut. In this embodiment, by removing the lids 25, 25', the magnetic assembly 6 is removed.
can be cleaned and replaced very easily.

Effects of the Invention Since the present invention has the above configuration, it can be installed in housings with various inner diameters by simply replacing the end plates and blocking plates with ones that match the inner diameter of the housing, so magnets of various sizes can be used. A magnetic processing device can be obtained using housings with various inner diameters without preparing a laminate and a porous cylindrical body. Further, since the blocking plate is provided, the water to be treated does not flow through the chamber formed between the housing and the porous cylindrical body and exit without being magnetically treated.

In addition, since magnetic pole pieces are used, it is possible to obtain a strong magnetic field that effectively acts on the magnetic treatment of water, and even when using a ferrite magnet with a large coercive force but a small residual magnetism, the magnetic treatment of water can be effectively performed. It can be done.

Moreover, since the magnetic pole piece and the magnet are stacked in many layers and the magnetic treatment is repeated, the effect of the magnetic treatment can be fully demonstrated.
