Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a purification device that uses magnetism to remove magnetic substances contained in liquid or gas.

[Prior Art] FIG. 4 is a sectional view showing the configuration of a conventional magnetic purification device. In the figure, 5 is the fluid to be purified;
6 is a magnetic particle, 7 is a conduit made of a non-magnetic material, 8
is a ring-shaped permanent magnet provided around the conduit 7 or a plurality of rectangular permanent magnets. Assuming that the fluid 5 to be purified flows in from the left side of the conduit 7, the magnetic particles 6 in the fluid 5 to be purified are attracted close to the magnetic poles of the permanent magnet 8 and removed, and the purified fluid 5 is removed. It flows out from the right side of conduit 7. In addition,
The permanent magnet 8 may be replaced by an electromagnet.

[Problems to be Solved by the Invention] In the conventional magnetic purification device as described above, the permanent magnet 8 is placed outside the conduit 7 and the strength of the magnetic field is weak, making it difficult to completely remove the magnetic particles 6. Not only is this impossible, but the magnetic particles 6 attracted near the magnetic poles of the permanent magnet 8 are in the flow path of the fluid 5 to be purified, so they are washed away and returned to the fluid 5 to be purified. There have been problems such as the ability to retain the removed magnetic particles 6 is weak, and the purifying device has to be constantly replaced and cleaned.

The present invention was made to solve these problems, and an object of the present invention is to provide a purification device that has a large purification ability and is capable of retaining the removed magnetic particles.

[Means for Solving the Problems] The purifying device according to the present invention uses a magnet plate that is magnetized so that the N and S magnetic poles appear only on one side (hereinafter referred to as one-sided magnetization), and that is arranged between both magnetic poles. One or more holes are provided in the magnetic plates, a spacer is inserted between the two magnetic plates, the same magnetic poles are made to face each other, and the holes are formed between the two magnetic poles by overlapping them against the repulsive force of the repulsive magnetic field. The fluid to be purified is made to flow through the pipe.

[Function] In the purification device of the present invention, two magnetic plates that have been magnetized on one side are stacked on top of each other with a spacer inserted between them so that the same magnetic poles face each other, so there is a very strong force between the two magnetic plates. A strong magnetic field is generated, and magnetic particles can be efficiently removed. Also,
Since the hole through which the fluid to be purified passes is made between both magnetic poles, the magnetic particles removed from the fluid to be purified gather at the magnetic pole part and exit from the flow of the fluid to be purified, so that the removed magnetic particles The particles will be retained without being carried away by the fluid to be purified.

[Example] Fig. 1 is a sectional view showing the configuration of a purification device which is an embodiment of the present invention, Fig. 2 is a perspective view showing the constituent members of the purification device, and Fig. 3 is a diagram showing the lines of magnetic force of the purification device. FIG. In the figure, 1 is a magnet plate made of, for example, a ferrite sintered body and magnetized on one side, 2 is a spacer, 3 is a case A, and 4
is case B, 5 is the fluid to be purified, 6 is the magnetic particle,
9 is a hole. As shown in FIG. 1, two magnet plates 1, 1 that have been magnetized on one side are placed so that the same magnetic poles face each other, and a spacer 2 is sandwiched between them.
Since the case A3 and the case B4 are superimposed against the repulsive force caused by the repulsive magnetic field, the lines of magnetic force are transmitted through the gap formed between the magnet plates 1 and 1, as shown in FIG. In this case, the density becomes extremely high and a strong magnetic field is formed. Therefore, when the fluid to be purified 5 is made to flow through the holes 9 provided in the non-magnetic part between the magnetic poles of the magnet plate 1, the magnetic particles 6 contained in the fluid to be purified 5 are attracted to the magnetic poles and removed. Since the magnetic particles 6 removed in this manner exit from the flow path of the fluid to be purified 5, there is no fear that they will be pushed out by the flow and mixed into the fluid to be purified 5 again. When this device is used to remove iron and the like contained in drinking water, since the amount of iron and the like contained in drinking water is minute, it can be used without the hassle of long-term cleaning. Further, this device can be used not only for purifying fluids such as liquids and gases, but also as a device for removing magnetic particles in powder made of non-magnetic material.

Note that this invention is not limited to the above-mentioned embodiments, and may be modified without departing from the gist of the invention.

[Effects of the Invention] As explained above, in a purification device, the present invention includes two magnet bodies magnetized on one side, which are stacked on top of each other with the same magnetic poles facing each other with a spacer in between. Since a hole is provided between the holes and the fluid to be purified is allowed to flow through the hole, the magnetic particles in the fluid to be purified can be removed extremely efficiently using a strong magnetic field, and the removed magnetic particles can be removed very efficiently. Since the particles are attracted to the magnetic pole part, excellent effects such as being retained without being swept away by the fluid to be purified can be achieved.
