Description

[Detailed description of the invention] [Industrial application field] This invention is used, for example, to remove red rust, scale, etc. formed in piping for water supply, hot water supply, etc. The present invention relates to a magnetic fluid device that can be placed in a water tank or the like to prevent rust, scale, etc. from forming inside the device.

[Technology behind the invention] When pipes for water supply and hot water supply in buildings are used for many years, the inner walls of the pipes corrode and develop red rust, and impurities in the water deposit. As the inner diameter of the pipe becomes smaller, the water pressure decreases, 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 off the rust, and then the lining is treated with epoxy resin, etc.; There is a method of lining the pipe after it has been scraped off, but it is difficult to line the pipe evenly within a long curved pipe, and there is the problem that red rust will re-occur in areas that have been incompletely lined. In addition, all of these had problems such as having to cut off water for long periods of time and being expensive.

In recent years, magnets have been installed in the middle of piping for water supply and hot water supply equipment, and magnetically treated water is passed through the piping because construction work can be carried out without water outages for long periods of time, there are no water quality issues, and the cost is low. This removes red rust that has formed on the inner wall of the pipe,
Alternatively, magnetic treatment methods are being adopted to prevent the formation of red rust and the deposition of impurities.

No final academic opinion has been given as to why red rust on the inner walls of pipes is removed by passing magnetically treated water through the pipes, or whether it prevents the formation of red rust and the deposition of impurities. However, by passing water through a magnetic field, impurities contained in the water, such as electrolytes present in the form of ions, non-electrolytes present in the form of molecules, microdispersed solid particles, and dissolved gases, are removed. It is thought that this is because it is subjected to magnetic and electrical effects, and undergoes physical and chemical changes.

BACKGROUND ART Various devices have been proposed in the past as devices that are installed in the middle of piping for water supply and hot water supply equipment to magnetically treat water. The present inventor also previously placed a magnet laminate in which magnetic pole pieces and magnets having through holes or notches on the periphery are alternately laminated inside a porous cylindrical body, and provided porous holes at both ends of the porous cylindrical body. An end plate having an outer diameter larger than the outer diameter of the cylindrical body and having a through hole through which water to be treated flows into the porous cylindrical body, and on the outer periphery of the porous cylindrical body, A magnetic treatment assembly provided with one or more blocking bodies for blocking the flow of water flowing around the outer periphery of the porous cylindrical body and returning the flow into the porous cylindrical body is disposed within the housing. The housed magnetic processing device (Patent Application No. 134172/1982) is a cylindrical body made of non-magnetic material with a spiral structure made of non-magnetic material provided on the outer periphery. Water magnetic treatment device formed by stacking layers at intervals through spacers (Utility patent application 174520/1986)
No.) was proposed.

These magnetic treatment devices can efficiently treat water magnetically, can effectively remove red rust formed on the inner walls of pipes, and are highly effective in preventing the formation of red rust and the deposition of impurities, but they are still Its structure is complex and the resistance to water flow is large.
Not only is it not cheap, but it also has to be installed in the middle of water supply, hot water supply, etc. piping, so it has the disadvantage that it takes a lot of work to install.

[Object of the Invention] Therefore, a first object of the present invention is to provide a magnetic fluid device that can efficiently perform magnetic processing.

A second object of the present invention is to provide a magnetorheological device that has a simple structure and can be easily installed.

A third object of the present invention is to provide a magnetic fluid device used as a filling material for water tanks and the like.

[Structure of the idea] The above object is achieved by the following configuration.

(1) A fluid magnetic processing filler made by laminating multiple flat ferrite magnets with spacers made of non-magnetic material interposed therebetween.

(2) The filler for fluid magnetic treatment according to item 1 above, which has a spherical outer shape.

(3) The filler for fluid magnetic treatment according to items 1 and 2 above, which is formed by laminating a plurality of flat plate-shaped ferrite magnets with their N poles facing each other and their S poles facing each other.

(4) The filler for fluid magnetic treatment as described in items 1 and 2 above, which is formed by laminating a plurality of flat plate-shaped ferrite magnets with their north and south poles facing each other.

(5) The filler for fluid magnetic treatment according to items 1 to 4 above, which is covered with a non-magnetic cover through which water can enter and exit.

(6) The filler for fluid magnetic treatment according to items 1 to 4 above, which is covered with a magnetic cover through which water can enter and exit.

(7) The filler for fluid magnetic processing according to item 6 above, wherein the magnetic cover is made of stainless steel.

(8) The filler for fluid magnetic processing according to item 6 above, wherein the magnetic cover is made of rust-prone iron or iron alloy.

The present invention will be explained in detail below.

There are various types of magnets such as ferrite-based magnets and alloy-based magnets, but ferrite-based magnets are inexpensive, and ferrite-based magnets are the best from various viewpoints such as effectiveness in water treatment. .

Ferrite magnets have weak mechanical strength and are easily chipped, but since the magnetic fluid device of the present invention is used while being left stationary in a water tank or the like, there is little chance of such a problem.

In addition, if you do not want the ferrite magnet to chip, you may directly cover the ferrite magnet with a synthetic resin, metal plate, etc.
The entire magnetorheological fluid device, which is made by laminating multiple flat ferrite magnets with spacers made of non-magnetic material, is made of a material that allows water to enter and exit (a material with many holes, such as punched metal). From the viewpoint of handling, it is preferable to cover and reinforce the material with a cover made of a material (such as netting, netting, etc.).

The water to be treated flows through the cover and is treated with the magnetorheological device.

The cover can be made of non-magnetic or magnetic material.

Non-magnetic materials include non-magnetic stainless steel,
Examples of the magnetic material include iron or iron alloys, such as steel, and magnetic stainless steel.

The magnets may be stacked with north poles facing north poles, south poles facing south poles, or stacked with north poles facing south poles.

When laminated with north poles facing north poles and south poles facing south poles, the effect of water treatment appears quickly. In addition, when stacking N and S poles facing each other, the effect of water treatment is slower than when stacking N and N poles and S and S poles, but the final The effectiveness of rust removal is excellent.
Therefore, it is preferable to mix and use both a magnetic fluid device in which N poles are stacked with N poles facing each other and S poles are stacked with S poles facing each other, and a magneto fluid device in which N poles are stacked with N poles facing S poles.

As the non-magnetic material constituting the spacer, there are no particular limitations, and there are no particular limitations on the non-magnetic material, such as stainless steel, non-magnetic metal materials such as copper and brass, ceramics, and synthetic resins, but corrosion-resistant materials are preferred.

A flat magnet and a spacer made of a non-magnetic material are laminated together using bolts and nuts made of a non-magnetic material or other fixing means.

The flat magnet can have various shapes, but is preferably circular. Further, it is preferable that the magnetic fluid device has a spherical shape as a whole because it allows dense filling and prevents damage to the magnet.

The magnetic fluid device of the present invention is used by being loaded into a water tank or the like.

The magnetorheological device of the present invention can also be used to magnetically treat liquids other than water, such as gasoline, kerosene, etc.
