As shown in Figures 2 to 5, the configuration of a low-power hybrid filter according to an embodiment of the present invention, the hollow ferromagnetic iron core (1) and the ferromagnetic iron core (1) of the hollow form providing a passage for the magnetic flux Permanent magnets 31, 32, 33, 34 having a large coercive force having the same polarity in the inner side, permanent magnets 41, 42 having a relatively low coercive force installed on another side of the iron core of the ferromagnetic material 1, and , Surrounding the periphery of the permanent magnets (41, 42) and the electric coils (51, 52) capable of supplying power and in contact with all one surface of each of the permanent magnets (31, 32, 33, 34, 41, 42) A filter matrix assembly 6 inserted between the magnetic poles 21 and 22, the magnetic poles 21 and 22, and having a built-in filter matrix (not shown), and permanent magnets 41 and 42 having low coercive force. Ferromagnetic iron core (1) while supplying power to the electric coils (51, 52) to change the polarity It comprises a direct current power supply (not shown) installed outside.

By the above configuration, the action of the low-power hybrid filter according to an embodiment of the present invention is as follows.

2 is a view showing the main part of a low-power hybrid filter according to an embodiment of the present invention, wherein a filter matrix assembly 6 having a filter matrix (not shown) is inserted between magnetic poles 21 and 22. By the control of the valves 7 installed on the upper and lower parts of the filter matrix assembly 6, it has been shown that the removal of iron contained in the mixture and the cleaning of the filter matrix assembly 6 are possible.

3 to 5 are views showing a specific structure of a low-power hybrid filter according to an embodiment of the present invention, wherein the coercive force is large on the inner upper and lower surfaces of the ferromagnetic iron core 1 made of a hollow ferromagnetic body that provides a passage for magnetic flux. The permanent magnets 31, 32, 33, and 34 are disposed to contact the ferromagnetic iron core 1, and the permanent magnets 41 and 42 having a relatively low coercive force on the inner left and right surfaces of the ferromagnetic iron core 1 are ferromagnetic iron cores ( 1) is installed in contact with the electric coils 51, 52, which can supply electric power to the periphery of the permanent magnets 41, 42, and each of the permanent magnets 31, 32, 33, 34, 41, 42. Ferromagnetic magnetic poles (21, 22) are provided in contact with all one side of the), and the filter matrix assembly (6) having a filter matrix (not shown) is inserted between the magnetic poles (21, 22) Is done.

In the case of installing the permanent magnets 31, 32, 33, and 34, the polarities of the permanent magnets 31 and 32 which are in contact with the magnetic pole 21 to form a magnetic field in the filter matrix assembly 6 are mutually different. It is installed to be the same, so that the polarity of the permanent magnets (33, 34) in contact with another magnetic pole 22 is the polarity opposite to the permanent magnets (31, 32) on the opposite side.

3 is a block diagram showing a magnetic field formed in the filter matrix assembly 6 of the low-power hybrid filter according to an embodiment of the present invention, and the permanent magnets 41 and 42 in the electric coils 51 and 52. ) Is set to the same polarity as that of the permanent magnets 31, 32, 33, and 34 in contact with the magnetic poles 21 and 22 by a DC power supply (not shown) installed outside the filter. When power is supplied, the magnetic flux Φ 21, Φ 12 of the permanent magnets 31, 32 passes through the magnetic pole 21 and passes through the filter matrix assembly 6, opposite the magnetic pole 22 and the permanent magnet. (33, 34) and the ferromagnetic adult core (1) is returned to the permanent magnets (31, 32), and at the same time the magnetic flux (Φ21, Φ22) generated by the permanent magnet 41 is the magnetic pole 21 Magnetic poles opposite and through the filter matrix assembly (6) By returning to the permanent magnet 41 through the permanent magnet 42 and the ferromagnetic iron core 1, a strong superposition magnetic field is formed in the filter matrix assembly 6.

In this case, even when the electric power supplied to the electric coils 51 and 52 is cut off, the polarity of each of the permanent magnets 41 and 42 is maintained as it is, and thus a strong superposition magnetic field can be continuously formed by the permanent magnets. .

In the case where a stronger magnetic field is required, when a very small amount of current flows through the electric coils 51 and 52, the magnetic field generated from the electric coils 51 and 52 by the small amount of current is filtered out. When applied to a stronger magnetic field is formed, the path of the magnetic flux is equal to Φ 21 and Φ 22.

Therefore, even if the electric current applied to the electric coils 51 and 25 is supplied only for a short time of about 1 second, the polarity of the permanent magnets 41 and 42 can be changed, thereby reducing electric energy. As in the electromagnet type filter, there is no need for a separate cooling device for cooling the electric coil, the overall size of the filter can be reduced, and the semi-permanent use can be made by eliminating the cause of the failure.

The magnetic flux (Φ31, Φ32, Φ33, Φ34) is returned to the permanent magnets (31, 32, 33, 34) through the magnetic poles (21, 22), the permanent magnets (41, 42), and the ferromagnetic iron core (1). The magnetic field is formed in the filter matrix assembly 6 by not passing through the filter matrix assembly 6. Do not.

In this case, even when the electric power supplied to the electric coils 51 and 52 is cut off, the polarity of each of the permanent magnets 41 and 42 is maintained, so that no magnetic field is formed in the filter matrix assembly 6.

Accordingly, even if the electric currents applied to the electric coils 51 and 25 are supplied only for a short time of about 1 second, the permanent magnets 41 and 42 can maintain the polarity corresponding to the polarity of the electric current. Energy savings can be achieved, and as in the case of electromagnet filters, there is no need for a separate cooling device to cool the electric coil, the overall size of the filters can be reduced, and the use of semi-permanent devices can be eliminated by eliminating the cause of failure. It becomes possible.

The filter is operated by returning back to the permanent magnet (42) through the magnetic pole (21), the permanent magnet (41), and the iron core (1) on the opposite side of (6). It is possible to form a magnetic field in a direction opposite to that of the magnetic field in the middle, so that the remaining magnetic field is removed from the filter matrix assembly 6. Therefore, in the present invention, it is possible to easily remove residual magnetism without installing a separate residual magnetism removal device.

In addition, in the present invention, the magnetic field direction of FIG. 3 and the magnetic field direction of FIG. 5 are periodically reversed, so that minute vibrations may be generated in the filter matrix assembly 6 without a separate vibrator, and thus may be easily cleaned.

In addition, in the present invention, even if the permanent magnets 31, 32, 33, 34 having a large coercive force and the permanent magnets 41, 42 having a relatively low coercive force are disposed to be interchanged with each other, the object of the present invention can be achieved.

As described in the above embodiment, the present invention, by using a combination of electromagnets and permanent magnets can take advantage of both the electromagnet filter and the permanent magnet filter, supplying the direct current power to the polarity of the relatively small coercive force It can be changed by the device to form a strong magnetic field in the filter matrix assembly, it can relatively reduce the power consumption significantly, generate a fine vibration to facilitate the cleaning, separate cooling device, vibration generator, etc. Its structure is simple and easy to maintain by allowing the effect to be achieved without installation.
