Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device specifically aimed at two uses.

Purpose 1 The purpose is to remove fine magnetic powder from the liquid by repeatedly passing the magnetic field lines within the device of the present invention. Application examples: Internal combustion engine lubrication systems, automatic transmissions, etc.

Purpose 2 The purpose is to prevent and remove scale adhesion to the inner walls and pipes of equipment that utilizes the device by causing liquid to repeatedly pass through the magnetic field lines of the device of the present invention. Application examples: Steam boilers, hot water boilers, household bathtubs, cooling systems for water-cooled internal combustion engines, etc.

Let me state in advance that it is known that there are devices that have the properties of objectives 1 and 2. For example, there is an iron powder removal device (magnetic oil filter) that has the same characteristics as objective 1, and is a device for removing iron powder contained in engine oil. There is a commercially available magnetic scale adhesion prevention device that has characteristics similar to the second objective.

Here, the differences between the device of the present invention and those devices will be explained in detail.

The structural difference between the device having the property of object 1 and the device of the present invention is that both devices utilize the property that a magnetic material is attracted to a permanent magnet. Regarding the above-mentioned device, the fine magnetic powder in the engine oil is directly attracted to the permanent magnet, and when the permanent magnet comes into contact with some of the magnetic material, it magnetizes the magnetic material, and the engine The fine magnetic powder in the oil is adsorbed to the magnetic material. Regarding the device of the present invention, there are cases in which magnetic powder in a liquid is directly adsorbed by a permanent magnet;
Instead of being directly attracted to a permanent magnet, magnetic powder is attracted to a pool of liquid in a liquid using lines of magnetic force generated from permanent magnets arranged on a cylinder (see Figure 1 and Figure 2).
Although this part is not in direct contact with the permanent magnet, there is also a partition plate (see Fig. 19, Fig. 2) and a turbulence plate (see Fig.
(see Figure 5) uses non-magnetic material, so
A permanent magnet does not function as a magnet due to its action; in other words, the adsorption reservoir (see Fig. 1, 9, and 2) does not directly touch the magnet, and is located at a position away from the permanent magnet, regardless of the action of the magnetic material. It has a structure that attracts and accumulates magnetic powder (see Fig. 1, 9, and 2).
This is a method of utilizing magnetic lines of force that cannot be seen anywhere else.

The difference in structure between the device having the property of purpose 2 and the device of the present invention is that both devices achieve the effect when the liquid passes through the lines of magnetic force generated by the permanent magnet, but they are not completely the same. However, there is a major difference between the previously described devices and the device of the present invention in the way the magnets are used. Regarding the device already mentioned, a round rod-shaped permanent magnet is placed in a tube with an inlet and an outlet, a spiral guide plate is provided around it, and the magnet is inserted through the inlet. The incoming water travels in a spiral around a round rod-shaped permanent magnet and is discharged from the discharge port. It passes through the lines of magnetic force that are generated. Regarding the device of the present invention, rod-shaped permanent magnets with a square cross section are arranged in a cylindrical shape, and the liquid flow passes through magnetic field line chambers A, B, C, D, and E (see Fig. 5). It has a structure in which the lines of magnetic force repeatedly pass through it. In addition, since it is designed to reliably capture magnetic powder in the liquid, among the magnetic force line chambers A, D, and E, which have the strongest magnetic force lines, magnetic force line chamber A has a magnetic powder adsorption reservoir ( (See page 14, line 14 to page 15, line 1) for a detailed explanation based on the figures in Figure 1, Figure 2, and the figures described later. It's summery.
For this reason, floating magnetic powder such as iron rust in the liquid in the equipment using the device of the present invention is attracted and the number of floating particles is greatly reduced. The effect is particularly noticeable when the liquid is circulated.

I have described a comparison between the device of the present invention and the previously mentioned devices, but needless to repeat, all devices use permanent magnets. This means that the same structure can achieve the effects of "removal of the body" (see objective 1 above) and "prevention and removal of scale" (see objective 2 above), and it is possible to achieve the same effect with the existing equipment. cannot be seen. Although this partially overlaps with the above, the major structural feature of the device of the present invention is that it utilizes vertical and horizontal lines of magnetic force. By arranging bar-shaped permanent magnets in the same direction (inner S to outer N pole or inner N to outer S pole), the inner and outer centers of each permanent magnet are divided into upper and lower parts, and the upper and lower ends are separated. They are each configured symmetrically. Since magnetic powder is attracted along the lines of magnetic force, the magnetic powder attraction reservoir (see Fig. 1, 9, and 2) is formed by the recess of the partition plate (see Fig. 1, 9, and 2). This is a major feature, as it allows the use of the vertical lines of magnetic force inside the cylindrical arrangement of rod-shaped permanent magnets, expanding the attraction area.

In addition, the horizontal magnetic lines of force (see Figure 3) connect the gap between adjacent permanent magnets to the magnetic field line chamber C (see Figure 5).
It is configured as

Five magnetic field line chambers are constituted by the magnetic field lines in these two directions, and the liquid is effectively in contact with the magnetic field lines from the time when it flows in from the suction port to the time when it is discharged from the discharge port, resulting in an effective structure.

For example, if this structure is used in a lubrication system for an internal combustion engine, the effect can be expected. It is either built into the oil element or connected to a part of the pipe line if an oil cooler or the like is installed. Reliably capturing magnetic powder in engine oil can reduce engine friction loss. This is the direct meaning of capturing the magnetic powder, but the following effects also appear as phenomena. The contact surface between the piston ring and the cylinder becomes smooth and airtightness increases (compression pressure increases by about 10%), resulting in better combustion conditions.
This results in reduced exhaust gas, improved fuel efficiency, and increased power. A reduction in nitrogen oxides is also seen due to the reduction in frictional heat within the cylinder. Furthermore, as the performance of modern automobiles and the quality of oil have improved, the time for oil changes has become longer. Most passenger cars are instructed to change the oil every 8,000km to 10,000km. However, the inventor interprets this to mean that the engine itself is not affected and the oil remains oily. Many owner-drivers have experienced that the engine runs smoothly immediately after changing the oil. If you actually compare the case where you change the oil every 1000km and the case where you change the oil every 5000km, you will see a difference of around 20%.
If the device of the present invention is installed here, the range will be 5000km.
Even if you change the oil every 1000 without installing anything
The effect is similar to that of changing the oil every kilometer. Furthermore, when comparing the same car after driving 5,000 km without installing the device of the present invention and after driving 5,000 km with the device installed, it was found that the fuel efficiency was improved by around 20%, the oil was less dirty, and the exhaust gas (CO , HC) reduced by 50 to 70% when idling (measured without introducing secondary air to the catalyst vehicle and without the catalyst functioning)
You can see the effects of

Similarly, regarding motorcycles that use a four-cycle engine, the engine oil and transmission oil are used together, so minute iron particles generated from the engine and minute iron particles generated from the gears of the transmission are mixed into the oil. Because of this, the oil deteriorates quickly, and unless you change it at around 2000km, which is earlier than the motorcycle's recommended replacement period (mostly 5000km), you won't be able to ride in good condition. When the device of the present invention was installed and a fuel consumption test was conducted, the elongation rate was significantly improved by 30%. Also, the oil gets dirty slowly.
When replaced at 5000km and at 2000km without installing anything
The level of dirt was the same as when it was replaced.

Purpose 2 is to prevent the formation of crystalline scale that adheres to heat exchange surfaces, valves, piping, etc. by installing the device of the present invention on a part of the pipe line of equipment that uses water. Can be done. Generally speaking, the solubility of solids dissolved in water increases as the water temperature rises, but on the other hand, the solubility of calcium carbonate, which forms the basis of scale, decreases as the water temperature rises. When water is heated, the calcium bicarbonate in the water decomposes, producing carbon dioxide, water, and calcium carbonate.

[Ca(HCO ₃ ) ₂ →CaCO ₃ +CO ₂ +H ₂ O] It is a well-known fact that magnetic treatment of water is effective in preventing and removing water scale from adhering to the inner wall. (Magnetic treatment of water began in 1945.
The Belgian patent No. 460560 granted to Te Bermain in 2010 is well known. ) As an example, when the device of the present invention is installed in the cooling system of a water-cooled internal combustion engine, floating minute red rust will be adsorbed, and scale attached to the inner walls of the engine, radiator, etc. will be peeled off, so it will absorb heat. It has improved conductivity and is an effective means to prevent overheating in older cars, which are often seen overheating in the summer.
When we actually removed the cylinder head of the engine, we found that there was a lot of scale on the inner wall of the water channel, and the area through which the coolant passes was 20%
The front and back are shrinking. This is a major cause of overheating. When I took out the coolant from the radiator into a container after driving 1000km with the device of the present invention installed, I found that the coolant was quite dirty. Also, when I removed the cylinder head, I saw that the inner wall of the waterway was quite clean. Also, household bathtubs have two holes in the bathtub (the lower part is the inlet and the upper part is the outlet for hot water), and if the device of the present invention is installed on the inlet side, it will be possible to heat the water. A small amount of scale from the bathtub came out from the outlet, making the water in the bathtub look quite dirty. This is evidence that the scale of the bath kettle has fallen, but the hot water is 5 to 6 times
If you wash it repeatedly, you will hardly see any dirt. At the same time, the time it takes to heat hot water is reduced by about 10%, leading to energy savings and being economical.

The present invention will be explained in detail below based on the lines of magnetic force due to the arrangement of permanent magnets shown in the drawings.

Reference numeral 1 denotes permanent magnets having a rectangular bar shape in cross section, which are arranged on the same circumference as shown in Figure 1.
The orientation of each magnet is the S pole on the inside of the circle and the N pole on the outside.
Take it as a pole. (The positions of the N and S poles may be changed.)
Both ends of this permanent magnet are fixed with partition plates shown in Figure 1 9 and 10, and 8 turbulence plates (using perforated plates) are installed inside the magnet to stabilize the magnet so that it does not succumb to the pressure of the fluid. Measure. These are fixed inside the cylindrical casing shown in 2, and outer covers 3 and 4 having liquid inlets and discharge ports are attached, and at the same time turbulence plates 5 and 7 are attached. FIG. 3 is a horizontal line of magnetic force diagram (see FIG. 6) and a vertical line of magnetic force diagram (see FIG. 7, FIG. 1). These lines of magnetic force are separated by a partition plate inside the casing (see Fig. 1, 9).
The magnetic field line room A shown in the figure is configured. By installing this partition plate, the fluid entering from the suction port changes its flow and flows around the outside of the cylindrical permanent magnet.
9 and 10), the magnetic force line chamber B is constructed by the casing and the permanent magnet. Next, the partition plate (Fig. 1
By reference, the fluid flows through the gap between adjacent permanent magnets arranged in a cylindrical shape, that is, the field line chamber C.
(See Figure 5). At this time, there is a turbulence plate using a perforated plate (see Figure 1, 8) to hold the permanent magnet, and just before the fluid flows into chamber D, it hits the turbulence plate and creates turbulence, causing magnetic particles in the liquid. It is clear that a turbulent flow is generated and the trajectory passing through the magnetic force line chamber C is longer than when the body directly touches and is attracted to the permanent magnet and the fluid flows out as a laminar flow. Next, when the fluid enters the inner magnetic field line chamber D of the permanent magnet arranged in a cylindrical shape, it hits the turbulence plate (see Fig. 1, 6) and generates turbulence, and the remaining magnetic powder is removed from the turbulence plate of the permanent magnet. It is attracted from above, especially the center part (third part) of the surface of the permanent magnet.
Since this is the point where the vertical lines of magnetic force branch upward and downward from the point (see figure), it is concentrated around this point and attracted. This means that when the permanent magnets are arranged in a cylindrical shape as in the present invention and the nail is moved from the upper end near the center of the circle with a string and lowered little by little to the bottom, the nail is attracted to the center of the magnet and the lower end It will never go down.

The fluid further flows into the magnetic field line chamber E, which is constituted by a partition plate, a turbulence plate, and a discharge side outer cover (see FIG. 1, 10, 7, and 4). Here again, it can be seen that the direction of the fluid is greatly changed by the turbulence plate 7, its trajectory becomes longer, and the lines of magnetic force in the E chamber are effectively utilized. The fluid that enters through the suction port is discharged to the outside through the discharge port through these paths.

The reason we installed turbulence plates 5 in room A and 7 in room E is because there are magnetic lines of force in the vertical direction (see Figure 8), and each turbulence plate causes turbulence and increases the number of times the lines of magnetic force pass through. It is. In addition, the recess (see Fig. 1 and Fig. 2) was provided in a part of the partition plate 9 (the inner part where the permanent magnets are arranged in a cylindrical shape) because the direction of the magnetic field lines (see Fig. 3) (See Figure 8), when the partition plate is flat, magnetic powder is concentrated at the upper end (suction port side) of the permanent magnets arranged in a cylindrical shape due to the flow of liquid (see Figure 9). Since there is a risk that the magnetic powder may be absorbed, a recess is provided to serve as a trap for the magnetic powder.

In order to maintain the distribution of magnetic lines of force (see FIG. 3) of the present invention, it is desirable that components other than the permanent magnets be made of non-magnetic materials.
