Abstract

PURPOSE:To remove Ca ion, Mg ion, etc. in water by providing a material for depositing salts in water consisting of a nonmagnetic material in a magnetic filed formed by a permanent magnet held in storage water and depositing and sticking the crystal of the ions in the water on the material for deposition. CONSTITUTION:The Ca ion and Mg ion in water deposit and stick on the surface on a nonmagnetic material 8 for deposition in the form of white salts such as CaCO3 and Mg(OH)2 in the magnetic field in the water formed by a permanent magnet body 5, thereby growing a crystal. The crystal is deposited to about 1cm thickness in four months and after the deposition of the crystal, the growth is fast. The crystal sticking on said material is easily removed from the material 8 when the crystal is touched by hand. The crystal is not deposited on a tank 1 formed of a stainless steel, a stainless steel hollow cylindrical body 6 covering the magnet body 5 and other conductive magnetic material. The scale of the Ca salt and Mg salt, etc. sticking to a water distributing pipe 3, the faucet at the terminal end, etc. are removed by the flow of the magnetic water.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for removing calcium ions, etc. in water using magnetism, and uses a magnet to remove calcium ions and magnesium ions in hard water, which cause scale adhesion. Regarding how to remove.

[Technical background of the invention and its problems]

Conventionally, water for baths using underground water or purified river water (tap water) is hard water and mainly contains calcium ions, magnesium ions, etc., which causes so-called insoluble scale that adheres to tanks, piping, faucets, etc. and causes rusting. This caused poor water flow. Methods for softening hard water include ion exchange and adding chemicals to precipitate water, but the former requires expensive ion exchange agents, while the latter requires chemicals and requires removal of precipitates. It is unsuitable for treating large amounts of hard water, such as those used in

[Purpose of the invention]

In view of the above-mentioned problems, the present invention has been developed by holding a permanent magnet in stored water to form a magnetic field in the water, providing an underwater salt precipitation material made of a non-magnetic material within this magnetic field, and adding salts of water ions to the precipitation material. It is intended to easily remove calcium ions, magnesium ions, etc. in water by depositing them.

[Summary of the invention]

In the present invention, a permanent magnet is held in stored water to form a magnetic field in the water, an underwater salt precipitation material made of a non-magnetic material is installed in this magnetic field, and salts of water ions are precipitated and adhered to this precipitation material. It is to be removed.

[Embodiments of the invention]

Embodiments of the invention will be described with reference to the accompanying drawings.

(1) is a stainless steel water tank, and is equipped with a water supply pipe (2) connected to an underground water source, water pipe, etc., and a water distribution pipe (3) connected to a bathtub or other place in a bathhouse. This water tank (
1) A pair of support frames (4) made of a non-magnetic material such as aluminum, duralumin, or synthetic resin are protruded inside the interior.
Several permanent magnet bodies (5) are installed on this support frame (4) with both ends supported. The permanent magnet (5) is placed inside the stainless steel hollow cylinder (6) at a height g such that the top and bottom are NS poles.
A large number of permanent magnets (7) with crrL, rh'gcm and thickness of 1cTL are stacked to approximately one length in the thickness direction via the same-shaped spacing material (9) made of non-magnetic material.
It is constructed to generate a Gaussian magnetic force, and a magnetic field of ln/ is formed around this permanent magnet (5). Further, around the permanent magnet body (5), precipitated materials (8) made of non-magnetic materials such as aluminum, duralumin, or synthetic resin and having a length of 100 cm, a width of 25 mm, and a thickness of 0.2 cm are placed at appropriate intervals within the magnetic field. It is protruded like a wing. Also, precipitation material (
The surface of item 8) is made uneven by sandblasting so that salt crystals can easily adhere to it.

Next, the operation of the above embodiment will be explained.

Calcium ions and magnesium ions in the water become white salts such as calcium carbonate and magnesium hydroxide in the underwater magnetic field formed by the permanent magnet (5) and deposit and adhere to the surface of the non-magnetic precipitation material (8). crystals grow. The crystals are precipitated to a thickness of approximately 1 crrL in 4 months, and the crystals grow rapidly after precipitation.

In addition, the attached crystals can be precipitated by touching them with your hands (8).

No crystals are deposited on other magnetically conductive materials. Also, so-called scales such as calcium salts and magnesium salts adhering to the water pipe (3), end faucet, shower nozzle, etc. are removed by the magnetic water flow.

In the above embodiments, the deposited material (8) is replaced by the permanent magnet (5).
Although it is attached to the support frame (4), it can also be attached to the support frame (4).
Furthermore, any attachment method may be used as long as it is within the magnetic field.

〔Effect of the invention〕

According to the present invention, a permanent magnet is held in stored water to form a magnetic field in the water, an underwater salt precipitation material made of a non-magnetic material is provided within this magnetic field, and crystals of underwater ions are precipitated and attached to this precipitation material. Therefore, ions in water that cause so-called scale can be removed more easily than conventional methods of ion exchange and chemical addition.
