Abstract

PURPOSE:To inhibit the adhesion of scale to the inner wall of an apparatus using a liquid, while attracting and removing a magnetic powdery body in the liquid, by letting the liquid flow through the vessel in which a plurality of permanent magnets are provided. CONSTITUTION:A plurality of stick-shaped magnets 1 having polygonal sections are arranged on the same circumference in a cylindrical casing 2 in a manner such that the S and N poles of each magnet are directed to the inside and the outside, respectively (The S and N poles may be reversely directed). An inner cylinder 8 comprising a porous plate is provided inside the group of the magnets, outer covers 3, 4 equipped with an inlet and an outlet for a liquid to be treated are attached to the both end parts of the inner cylinder 8, and plates 5, 7 for a turbulent flow are also provided. The interior of the casing 2 is divided into five magnetic force line chambers by partition plates 9, 10. During the passage of the liquid through each chamber, magnetic powder contained in it is positively attracted and removed from it, and the same electricity as that of the apparatus through which the liquid flows is applied to CaCO3 dissolved in the liquid so that particles repel each other to inhibit the formation of crystalline scale on the inner wall.

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 liquid through the magnet wire in the device of the present invention. Application examples: Internal combustion engine lubrication systems, automatic transmissions, etc.

Purpose 2. The purpose of this invention is to prevent and remove scale from adhering 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. Application examples: Steam boilers, hot water boilers, household bathtubs, cooling systems for water-cooled internal combustion engines, etc.

I would like to mention in advance that there are some devices that have been granted patents that have the characteristics 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, which 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, the magnetic material is magnetized, and the engine oil The fine magnetic powder inside is designed to be attracted to the magnetic material. Regarding the device of the present invention, there are cases in which the magnetic powder in the liquid is directly attracted to the permanent magnet, and there is also a case where the magnetic powder in the liquid is directly attracted to the permanent magnet. Adsorption pool of magnetic powder in liquid (see explanation of the figure and photo 1.3 below)
This is a unique method of utilizing magnetic lines of force, as this part has the strongest magnetic force.

The structural difference between the device with the property of purpose 2 and the device of the present invention is that both of them are generated by magnetism generated from a permanent magnet (3). Although they are of the same quality, 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 single original rod-shaped permanent magnet is placed inside a tube with an inlet and an outlet,
Instead, a spiral-shaped guide plate is provided, and the water that enters from the inlet travels in a spiral shape along the rod-shaped permanent magnet of the original mold and is discharged from the outlet. As it spirals around the magnet, it passes through the lines of magnetic force generated by the original permanent bar magnet. Regarding the device of the present invention, rod-shaped permanent magnets with a square cross section are arranged in a cylindrical shape, and liquid! The body flow passes through the magnetic field lines A, B, C, D, and E (see Figure 5), and is structured to repeatedly pass through the magnetic field lines. In addition, since it is designed to reliably capture the magnetic powder in the liquid, the magnetic field line chamber A, which has the strongest magnetic field lines, is equipped with a magnetic powder adsorption reservoir (detailed explanation based on the diagram below). A major feature of the present invention is that it has a structure (4) that attracts magnetic powder in the liquid. For this reason, floating magnetic powder such as iron rust in the liquid in the equipment using the device of the present invention is adsorbed, and the amount of floating particles is greatly reduced. The effect is particularly noticeable when the liquid is circulated.

I have described the comparison between the device of the present invention and the previously mentioned devices, but I will repeat 1.
However, all of them are devices that use permanent magnets.
The major features of the present invention are the effects of ``removal of fine magnetic powder contained in liquid'' (see objective 1 above) and ``prevention and removal of scale adhesion'' (see objective 2 above). can be obtained with the same structure, and is not found in previously released devices. Although some of the above 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, and uses the inner, outer, and both ends of permanent magnets arranged in a cylindrical shape.
The space between the magnets is divided into five magnetic field line chambers (see Figure 5) by a partition plate and the magnet itself, and a turbulence plate is installed at each location, allowing the liquid to repeatedly pass through the magnetic field lines over and over again. The reason is that the magnetic powder is attracted.

For example, if this structure is used in a lubrication system for an internal combustion engine, the effect can be expected. It is used either built into the oil element or connected to a part of the pipe line if an oil cooler is installed. Reliably capturing magnetic powder in engine oil can reduce engine friction loss. This has a direct meaning of capturing magnetic powder, but the following effects have also appeared as phenomena. The contact surface between the cylinder and the piston becomes smooth and airtightness increases (compression pressure increases by about 10%), resulting in better combustion conditions. Therefore the reduction of exhaust gases,
This leads to improved fuel efficiency and increased power. In addition, a reduction in nitrogen oxides was also observed due to the reduction in frictional heat within the 7linder. In addition, it has led to improvements in the performance of recent automobiles and the quality of oil.
It's too late to change the oil. Most passenger cars are instructed to change the oil between 8,000km and 110,000km. However, the inventor interprets this to mean that there is no problem with the engine itself and that the oil remains oily. Many owner-drivers believe that the engine runs smoothly immediately after changing the oil. I have experienced being driven. Actually 11
If you compare the case where the oil is changed every 000Km and the case where the oil is changed every 5000Km, you will see a difference of around 20%. If the device of the present invention is installed here, even if the oil is changed every 5,000K, the same effect can be obtained as when the oil is changed every 11,000K without any installation. Furthermore, in 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.
A comparison after 000 miles of driving shows that the fuel efficiency has improved by around 20%, the oil is less dirty, and the exhaust gas (Co, HC) has improved by around 20%.
) 50 to 70% reduction when measured during idle link (measured without introducing secondary air and without making the catalyst work)
You can see the effects of

Similarly, regarding motorcycles that use the four-cycle system, the engine oil and transmission oil are used together, so the minute iron particles generated from the engine and the minute iron particles generated from the gears of the transmission are mixed into the oil ( 7) Because it mixes with the oil, it accelerates the deterioration of the oil, and the replacement period indicated by the auto pipe (many are 500
If you don't replace it at around 2000km earlier than 0m), you won't be able to drive in good condition. When the device of the present invention was installed and a fuel consumption test was carried out, the elongation rate was significantly improved by 30%.

Also, the degree of oil contamination was slow, and the level of contamination was the same when it was replaced at 5000Kffl and when it was replaced at about 2000KrL1 without installing anything.

The second purpose is to install the device of the present invention on a part of the pipe line of equipment that uses water, so that it can be used on heat exchange surfaces, valves, etc.
It is possible to prevent the formation of crystalline scale that adheres to piping, etc. 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(HCO3)2] → CaCO3+CO2+H2
0(8) Calcium carbonate dissolved in this water is given the same negative charge by passing through the lines of magnetic force. In addition, the internal walls of the equipment and pipes are negatively charged and repel each other, making it possible to prevent the formation of crystalline scale. At the same time, it is possible to peel off the scale that was attached before installing the device of the present invention. This is because, as explained above, the inner walls of equipment and pipes are negatively charged, so positively charged fine powder particles are attached to them, but some negatively charged fine powder particles obtained by passing through the magnetic field lines This effect is obtained by adsorbing these things one by one.

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 is adsorbed,
Also, since the scale attached to the inner walls of the engine, radiator, etc. is removed, thermal conductivity improves, and old cars that have been used for many years often overheat in the summer. is also an effective method.

When we actually removed the cylinder head of the machine, we found that there was a lot of scale attached to the inner part of the water channel, and the area through which the coolant passed had been reduced by about 20%. This is a major cause of overheating. When I installed the device of the present invention and took out the coolant from the radiator into a container after driving for 1000 miles, I found that the coolant was quite dirty.

Also, when you remove the cylinder head, you can see that the inner wall of the waterway is quite clean.

In addition, household bathtubs have two holes in the bathtub (the lower part is the inlet and the upper part is the outlet for hot water), but if the device of the present invention is installed on the inlet side, the hot water can be poured out. When flushing, small amounts of scale from the bathtub come out of 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
If you wash it six times, you will hardly see any dirt. At the same time, the time required to prepare hot water is reduced by about 10%, which leads to energy savings and is also economical.

The present invention will be described in detail below based on lines of magnetic force based on a permanent magnet arrangement model shown in the drawings and photographs.

(2) Permanent magnets each having a rectangular bar shape in cross section are arranged on the same circumference as shown in FIG. 1, and the orientation of each magnet is such that the inside of the circle is the S pole and the outside is the N 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 Figures 9 and 10. ) to stabilize the magnet so that it does not succumb to the pressure of the fluid. These are fixed inside the cylindrical casing shown in 2, and outer covers 3 and 4 having a liquid inlet and outlet are attached, and at the same time a 5.7 turbulence plate is attached. Figure 2 is a horizontal magnetic field line diagram (see Photo 1), and Figure 3 is a vertical magnetic field line diagram (see Photo 2). If the flow of the fluid is changed by a partition plate inside the casing, these lines of magnetic force can be converted into ABC as shown in Figure 5.
Configure each magnetic field line room of DE. That is, the liquid entering from the suction port passes through the 5 turbulence plates, enters the A chamber, enters the B chamber from the end of the P partition plate 9, and from the B chamber passes through the C chamber between the permanent magnets and enters the D chamber. In chamber D, a cylindrical turbulent flow plate using a perforated plate as shown in 6 is installed to increase the number of times the liquid that collects in the center passes through the Gaka line.Furthermore, (11) enters chamber E. The turbulent flow is repeated by seven turbulent flow plates near the discharge port, and then exits to the discharge port.

The reason why we installed 5 turbulent flow plates in room A and 7 in room E is that there are cylindrical magnetic lines of force (see photo 3), and each turbulence plate creates turbulence to increase the number of times the lines of magnetic force pass through. It is for the purpose of Also, the reason why there is a recess in a part of the partition plate 9 (the part inside where the permanent magnets are arranged in a cylindrical shape) is related to the direction of the magnetic lines of force (see Photo 3), as shown in Figure 3. If the partition plate is flat, there is a risk that magnetic powder will concentrate at the end of the permanent magnets arranged in a cylindrical shape due to the flow of liquid (see Photo 4). That is.

Details of the amendment Name of the invention Device for removing magnetic powder contained in liquid and preventing and removing scale adhesion. 2 Claims: Inside a container having a lid with an inlet and an outlet on both sides of a cylindrical casing, rod-shaped permanent magnets with a square cross section are arranged in a cylindrical shape on the same circumference, and the magnets are in instant contact with each other. The distance is determined by the distance at which the mutual magnets repel each other, and the distance between adjacent magnets of the sentence names is set at equal intervals. Partition plates (see FIG. 1, 9.10) are provided at both ends of the rod-shaped permanent magnet, and the rod-shaped permanent magnet arranged in a cylindrical shape is fixed together with a holding plate (see FIG. 1, #8) inside the magnet. With this structure, a magnetic field line chamber consisting of five chambers (see Fig. 5, 1) is obtained, and the liquid that enters from the suction port passes through the magnetic field lines repeatedly to remove magnetic powder from the liquid and equipment that uses this device. scale adhesion prevention and removal equipment. (1) Detailed Description of the Invention The present invention is a device specifically aimed at two uses. Purpose 14 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. I would like to mention in advance that there are some devices that have been granted patents that have the characteristics 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, which 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 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 the permanent foundation stone and some of the magnetic material come in contact with each other, magnetizing the magnetic material, and the engine oil The fine magnetic powder inside is made to be attracted to the magnetic material. Regarding the device of the present invention, there are cases in which the magnetic powder in the liquid is directly attracted to the permanent magnet, and a method in which the magnetic powder in the liquid is directly attracted to the permanent magnet. There is an adsorption reservoir for magnetic powder inside (see the explanation of the figure and photo 1.8 below) to indirectly attract the magnetic powder, and this part has the strongest magnetic force, especially for other particles. This is a method of utilizing magnetic lines of force rarely seen in Japan. The structural difference between the device having the property of purpose 2 and the device of the present invention is that they both have the same effect in that the effect is obtained when the liquid passes through the lines of magnetic force generated by the permanent magnet. 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 previously mentioned device, there is a tube inside which has an inlet and an outlet.
A round rod-shaped permanent magnet is arranged, and a spiral-shaped guide plate is provided around it. Water entering from the inlet goes in a spiral along the round rod-shaped permanent magnet and exits from the outlet. When water travels in a spiral around a round bar-shaped magnet, it passes through the lines of magnetic force generated by the round permanent bar-shaped magnet. Regarding the device of the present invention, rod-shaped permanent magnets with a square cross section are arranged in a cylindrical shape, and the flow of liquid is carried out in magnetic field chambers A, B, C, D, and E (fifth
(see figure), and repeatedly passes through the lines of magnetic force. In addition, since it is designed to reliably capture the magnetic powder in the liquid, the magnetic field line chamber A, which has the strongest magnetic field lines, is equipped with a magnetic powder adsorption reservoir (detailed explanation based on the diagram below). A major feature of the present invention is that it has a structure (4) that attracts magnetic powder in the liquid. For this reason, floating magnetic powder such as iron or steel 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 it goes without saying that all of them are devices that utilize permanent magnets.
The major features of the present invention are the effects of ``removal of fine magnetic powder contained in liquid'' (see objective 1 above) and ``prevention and removal of scale adhesion'' (see objective 2 above). can be obtained with the same structure, and is not found in previously released devices. Although some of the above 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, and uses the inner, outer, and both ends of permanent magnets arranged in a cylindrical shape.
The space between the magnets is divided into five magnetic field line chambers (see Figure 5) by a partition plate and the magnet itself, and a turbulent flow plate is installed at each location. The reason is that the magnetic powder is attracted. (5) For example, if this structure is used in a lubrication system for an internal combustion engine, the effect can be expected. It is used either built into the oil element or connected to a part of the pipe line if an oil cooler is installed. Reliably capturing magnetic powder in engine oil can reduce engine friction loss. This is a direct meaning of trapping magnetic powder, but the following effects also appear as phenomena. The smoother contact surface between the piston and cylinder increases airtightness (compression pressure increases by about 10%) and improves combustion conditions. Therefore the reduction of exhaust gases,
This leads to improved fuel efficiency and increased power. A reduction in nitrogen oxides is also seen due to the reduction in frictional heat within the cylinder. In addition, it has led to improvements in the performance of recent automobiles and the quality of oil.
It's too late to change the oil. In the case of most passenger cars, it is instructed to change the oil every 8,000 to 1'0,000 b. 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 1000 KII and the case where you change the oil every 5000km, you will see a difference of about 20%. When the device of the present invention is installed, even if the oil is changed every 5,000 rsn, the same effect as when the oil is changed every 100 rsn without the installation is obtained. Furthermore, in the same car, 5,000
Comparing the results after driving Km and after driving 5,000 km after installing the product, the fuel efficiency has improved by 20%, the oil is less dirty, and the exhaust gas (Co, HC'I) has been measured when idling. You can see the effect of 50 to 70% reduction (measured without introducing secondary air to the catalyst vehicle and without making the catalyst work).Similarly, regarding motorcycles that use a four-stroke cycle, engine oil and transmission Since the oil is used for both purposes, minute iron particles generated from the engine and minute iron particles generated from the gears of the transmission mix into the oil, which accelerates the deterioration of the oil and makes it difficult for the motorcycle to operate properly. 2000K earlier than the current replacement period (mostly 5000m)
1. You won't be able to drive in good condition if you don't replace it every 1 hour. When the device of the present invention was installed and a fuel consumption test was carried out, the elongation rate was significantly improved by 30%. Also, the level of oil contamination is slow.
When replacing with 50ooK11 and when replacing with 20ooK11 and without installing anything
The level of dirt was about the same as when replacing it at about 00b. The second purpose is to install the device of the present invention on a part of the pipe line of equipment that uses water, so that it can be used on heat exchange surfaces, valves,
It is possible to prevent the formation of crystalline scale that adheres to piping, etc. Generally speaking, the solubility of solids dissolved in water increases as the water wetness increases, but the solubility of calcium carbonate, which forms the basis of scale, decreases as the water temperature increases. When water is heated, the calcium bicarbonate in the water decomposes, producing carbon dioxide, water, and calcium carbonate. [C&(I(C08)2]→C&CO8+Co□+1(
20(8) Calcium carbonate dissolved in this water is given the same negative charge by passing through the magnetic lines of force. In addition, the internal walls of the equipment and pipes are negatively charged and repel each other, making it possible to prevent the formation of crystalline scale. At the same time, it is possible to peel off the scale that was attached before installing the device of the present invention. As explained above, the inner walls of equipment and pipes are negatively charged, so positively charged fine powder particles are attached to them. This effect is obtained because the particles adsorb these little by little. 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 is adsorbed,
Also, since the scale attached to the inner walls of the engine, radian, etc. is removed, thermal conductivity improves, and old cars that have been used for many years often overheat in the summer. is also an effective method. In fact, when we removed the cylinder head of a second engine, we found that there was considerable scale on the inner wall of the waterway (9), and the area through which the coolant passed was reduced by 20%11.
It is shrinking after 1. This is a major cause of overheating. When I installed the device of the present invention and took out the coolant from the radiator into a container after driving for 100 degrees, I found that the coolant was quite dirty. Also, when you remove the cylinder head, you can see that the inner wall of the waterway is quite clean. In addition, a household bathtub has two holes in the bathtub (one part is an inlet and the upper part is an outlet for hot water), and the device of the present invention can be placed on the inlet side. When I boiled the water, a small amount of scale from the bathtub came out from the outlet [] and the water in the bathtub looked dirty. This is evidence that the scale of the bath kettle has fallen, but the hot water
If you wash it six times, you will hardly see any dirt. At the same time, the time required to prepare hot water is reduced by about 10%, which leads to energy savings and is also economical. Hereinafter, the present invention will be explained in detail based on magnetic lines of force based on a permanent magnet arrangement model shown in a photograph. 1 is a permanent magnet formed into a rectangular bar shape in cross section.These are arranged on the circumference as shown in Figure 1, and the orientation of each magnet is such that the inside of the circle is the S pole and the outside is the N 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 9.10, and inside the magnet there are 8 inner cylinders (using a perforated plate) ) to stabilize the magnet so that it does not succumb to the pressure of the fluid. These are fixed inside the cylindrical casing shown in 2, and an outer cover 3.4 having a liquid inlet and outlet is attached, and at the same time, a turbulence plate 7 is added. Figure 2 is a diagram of lines of magnetic force in the horizontal direction (see photo 1), and Figure 8 is a diagram of lines of magnetic force in the overlapping direction (see photo 2). If the flow of the fluid is changed by a partition plate inside the casing, these lines of magnetic force can be converted into ABC as shown in Figure 5.
Configure each magnetic field line room of DE. That is, the liquid entering from the suction port passes through the 5 turbulence plates, enters the A chamber, enters the B chamber from the end of the partition plate 9, and from the B chamber passes through the C chamber between the permanent magnets and enters the D chamber. In chamber D, a cylindrical turbulent flow plate using a perforated plate as shown in 6 is provided to increase the number of passages of the magnetic lines of force of the liquid gathered at the center. Further, it enters the E chamber, repeats turbulence on seven turbulence plates near the discharge port, and exits to the discharge port. The reason why we installed 5 turbulence plates in room A and 7 in room E is that there are cylindrical magnetic lines of force (see photo It is for the purpose of Also, the reason why there is a recess in a part of the partition plate 9 (inner part where the permanent magnets are arranged in an M-shape) is related to the surface drawing of the magnetic lines of force (see Photo 8), as shown in Figure 8. If the partition plate is flat, there is a risk that magnetic powder will concentrate at the end of the permanent magnets arranged in a cylindrical shape due to the flow of liquid (see Photo 4). This is an adsorption reservoir. BRIEF DESCRIPTION OF THE DRAWINGS The drawings all show embodiments of the device according to the present invention.
