The present invention relates to a scale preventing device of a pipe, which prevents scale from occurring when a fluid such as water or oil continuously flows in a pipe, and makes the water alkaline by ionizing the water and oil. will be.

Conventionally, when the electromagnet is fixed to the outer wall or the inner wall of the tube in order to prevent the scale formed in the tube, when the power is applied to the electromagnet, the magnetic force is generated to remove the scale.

However, such a conventional device reduces the influence of electromagnets due to the coercive role of the pipes, and thus affects the weakness of the iron loss or the shielding of the magnetic force due to the thickness of the pipe and thus the low strength of the magnetic force. It could not be completely prevented, and there was a lot of difficulties in the installation because there was no means for installing the electromagnet in the pipe.

In addition, when the installation position of the electromagnet is changed accordingly, the coercive force, which is the main magnetic force derivative, is lost due to hysteresis, or the magnetic field is rapidly reduced to the mutual reciprocity, and a separate power source is required due to the use of the electromagnet. There was a flaw.

In addition, in the conventional apparatus, since the size of the electromagnet should be increased as the diameter of the pipe is increased and the scale removing device is installed, the manufacturing cost increases due to this.

The present invention was conceived in view of the above-mentioned drawbacks of the prior art, and the magnetic yoke is installed above the pair of permanent magnets, and the magnet protection yoke is installed below and the magnet protection yoke is exposed downward. In order to be able to fix the body of the scale remover to any position of the pipe with an aluminum case, it will be described in more detail by the accompanying drawings, Figures 1 to 4 shown in the embodiment as follows.

1 is an exploded perspective view of the device of the present invention, 2 is a cross-sectional view of the first view.

The yoke 4 is fixed so that the magnetic force lines are moved above the pair of permanent magnets 2 and 3 installed inside the main body 1, and the permanent magnets 2 from the outside are disposed below the permanent magnets 2 and 3. Magnet protective yoke (5) and (6) for protecting (3) are fixed and integrally injected with a non-magnetic material to expose the magnet protective yoke (5) and (6) downward, and the magnet protective yoke (5) (6). ) Is connected to the pipe 7.

Then, the upper cover 8 and the lower cover 9 made of non-magnetic material such as aluminum or copper having good thermal conductivity for fixing the main body 1 having the permanent magnets 2 and 3 to the pipe 7 are separated. On the inner side surface of each cover 8, 9, the protrusion pieces 8a and 8b for shielding the recessed part 1a formed in the main body 1 are formed.

Therefore, when the magnet protective yoke 5, 6 exposed below the main body 1 is connected to the pipe 7 and the lids 8 and 9 are fastened with screws 10, the main body 1 is connected to the pipe 7. ) To prevent flow.

At this time, the permanent magnets (2) and (3) can be used as a ferrite magnet having the original magnetic strength in accordance with the heat or environmental changes, it is more preferable to use a rare earth magnet with a large magnetization force.

Referring to the effect of the present invention configured as described above are as follows.

The magnetic protection yoke (5) (6) exposed to the lower side of the main body (1) is connected to the site where it is installed by the pipe (7), and at the same time the projection (8a) formed on the lower cover (9) is attached to the main body (1). Inserted into the concave inlet (1a) formed on the cover, and covers the upper cover (8), and then tighten the screw (10) is secured firmly to the predetermined position of the pipe (7).

In such a state, when fluid such as water or oil flows in the pipe 7, magnetic force lines are generated in the deformed yoke 4 installed above the magnets 2 and 3, causing heavy metals and metals to cause the scale contained in the fluid. ions ^{(Ca ++, Mg ++, SiO} 2 ++ , etc.) by the law of lens Fleming's law and neutral elements (Ca °, Mg °, SiO 2 °) or ionized ^{(Ca -, Mg -, SiO} 2 - Therefore, it becomes the same pole (-) in the pipe, so it is repulsed and neutralized.

At this time, the cover (8) (9) for fixing the body (1) is a non-magnetic material such as aluminum copper having a good thermal conductivity in the case of a hot water boiler pipe quickly discharges the heat of the fluid into the atmosphere, due to the heat of the fluid permanent magnet ( 2) (3) is to prevent the magnetic force is lowered as well as to prevent the magnetic force is transmitted to the outside of the main body 1 when moving through the magnetic yoke yoke (4).

Therefore, the present invention is because the magnetic force of the permanent magnet (2) (3) is moved by the yoke yoke 4, the magnetic force acts on the surface of the pipe (7) widely. If the material of the pipe is made of nonmagnetic material (stainless steel, PVC, etc.), the magnetic protective yoke (5) (6) drills a hole in the area connected to the pipe and welds the magnetic material to the hole to protect the magnetic protective yoke (5). If (6) is installed to be connected, it is possible to prevent the scale in the pipe made of nonmagnetic material by using this design device.

As described above, the device of the present invention can be installed at any position of the pipe 7 by using the cover 8, 9, so that the installation is easy, and the permanent magnet 2, 3 can be installed. It is possible to maintain a constant magnetization force by using) so that heavy metals and metal ions are chlorinated by the device of the present invention as it passes through the pipe and loses the bonding force, thereby preventing the scale.

In addition, even when the diameter of the pipe is large, the magnetic force can be widely distributed in the pipe 7 by dividing the magnet by using the yoke 4, so that unlike the conventional apparatus using a large magnet, a small permanent magnet Since (2) and (3) is used, there is an effect that can reduce the production cost.

Claims (1)

In the case where a plurality of permanent magnets are arranged outside the pipe, a pair of permanent magnets (2) and (3) are incorporated inside the main body (1) made of a nonmagnetic material, and above the permanent magnets (2) and (3). The yoke 4 is fixed and the magnet protective yoke 5 and 6 are fixed to the lower side of the permanent magnet 2 and 3 so that the main body 1 has good thermal conductivity and shields the magnetizing force. Anti-scale device of the pipe, characterized in that to be fixed to the pipe (7) by the upper cover (8) and the lower cover (9) of the material.
