BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic filter for applying a magnetic field to a liquid, and relates to a magnetic filter used for improving the combustion efficiency of fuel oil and preventing scale adhesion of a fluid pipeline.

[0002]

2. Description of the Related Art It is known that when a magnetic field is applied to a liquid, aggregated impurities in the liquid are decomposed and dispersed in fine particles, and charging and activation of liquid molecules occur. That is, when the fluid flows, it is charged electrostatically by its own friction. When the charged body moves in a magnetic field, the flow velocity in the traveling direction is partially converted into a rotational vortex movement of the charged body, and the collision between the charged bodies becomes vigorous, whereby the molecules are activated. When the charged body whirls, new magnetic lines of force are generated, and this movement is further complicated and the activation is further promoted.

As described above, as a configuration for applying a magnetic field to a liquid, as disclosed in Japanese Utility Model Publication No. 60-28559, a plurality of magnets are provided outside a non-magnetic housing pipe through which a liquid to be treated flows. Are arranged in the axial direction so that the polarities of the opposing surfaces are the same, and a magnet filter in which a spiral guide member is provided inside the housing pipe has been proposed.

[0004]

In the above-mentioned magnet filter, due to its use, iron powder or the like magnetized by a magnet adheres and accumulates on the surface of the spiral guide member, obstructing the flow of liquid. Further, oil or the like also enters and adheres between the magnet and the housing pipe, which causes the magnetic force to weaken. The present invention eliminates such problems,
It is an object of the present invention to provide a magnet filter having a cleaning function.

[0005]

According to the present invention, a non-magnetic housing pipe through which a liquid to be treated flows is divided axially into a magnetized portion and a magnetically interrupted portion having substantially the same length. A spiral guide member is installed inside the pipe, a magnetic body is provided around the inside of the housing pipe of the magnetic blocking part, and a plurality of magnets are placed in the outer cylinder in the axial direction so that the polarities of the opposing surfaces are the same. A magnetic sliding body having substantially the same length as each of the parts arranged in a row is slidably provided outside the housing pipe, and the magnetic sliding body is moved in the axial direction to magnetize the magnetic processing unit and the magnetic processing unit. It is characterized in that it can be converted into two positions of the blocking part.

[0006]

When the magnetic sliding body is positioned in the magnetized processing section, the magnetized processing section passes through the non-magnetic housing pipe by the magnetic sliding body, and a magnetic field acts in the pipe. Since the magnetic field is disposed so that the polarities of the opposing surfaces of the magnet are the same, the polarities of the magnetic field are alternately reversed along the axial direction. Then, the liquid to be treated flows down as a vortex by the spiral guide member in the housing pipe, and receives the action of the above-described magnetic field, thereby charging and activating the liquid molecules.

[0007] When the magnetizing process of the liquid is continued, the magnetized iron powder adheres to and accumulates on the surface of the spiral guide member. Then, the outside of the non-magnetic housing pipe is slid, and the magnetic sliding body is moved to the magnetic interrupting section, and is magnetically shielded by the magnetic body of the magnetic interrupting section, thereby eliminating the magnetic field of the magnetization processing section. Thus, the iron powder deposited on the guide member is demagnetized, the joining by the magnetic force is released, and the iron powder flows down together with the liquid to be treated, thereby cleaning the guide member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a magnet filter 1 of the present invention, which is mainly composed of a non-magnetic housing pipe 2.

On the inner surface of the front end of the non-magnetic housing pipe 2, there is formed a female screw 3 for connecting the pipe 2 to a required pipe, and at the rear end, an annular screw formed with the female screw 5 as well. The mounting bracket 4 is externally fitted and fixed. The non-magnetic housing pipe 2 has a front half as a magnetization processing part x and a rear half as a magnetic shut-off part y. It is assumed that the lengths of the magnetization processing unit x and the magnetic blocking unit y are substantially equal. A spiral guide member 7 made of a spring is provided in the magnetization processing section x. The spiral guide member 7 generates a spiral flow in the liquid to be processed by turning the spiral guide member 7 to supplement the spiral motion of the fluid. In addition to the spring, a ring-shaped twisting element (see Japanese Utility Model Publication No. 60-28559), etc. Various members can be applied. In addition, a magnetic body 9 is provided around the inner surface of the magnetic blocking unit y.

A magnetic sliding body 10 is fitted around the outer periphery of the non-magnetic housing pipe 2. This magnetic sliding body 10
A plurality of magnets 12 and washers 13 inside an outer cylinder 11
Are alternately arranged, and are held by a locking ring 14 engaged with the inner surface on the rear end side of the magnetic sliding body 10 and a female screw 15 screwed on the front end side of the magnetic sliding body 10. Is done. The magnets 12 are arranged along the axial direction so that the opposite surfaces have the same polarity. Also, this magnetic sliding body 10
Is approximately equal to the lengths of the magnetization processing section x and the magnetic blocking section y.
The front end is locked by a locking ring 16 fitted to the front edge of the non-magnetic housing pipe 2 and positioned at the magnetization processing part x as shown by the solid line in FIG.
0 is in contact with the inner surface of the mounting bracket 4 so that the magnetic shut-off portion y
, The magnetization processing section x and the magnetic interruption section y
Sliding between them is possible.

Next, the operation of the above configuration will be described.
Pipe lines 30, 31 are screwed into the female screw 3 on the upstream side and the female screw 5 on the downstream side, and the magnet filter 1 is interposed in the required flow path, and the liquid to be treated flows in from the mouth end. And
In the state where the magnetic sliding body 10 is positioned at the magnetization processing part x, the magnetization processing part x has the same polarity as the magnet 12 facing, so that the polarity of the magnetic field is along the axial direction. To alternately flip. Therefore, the liquid flowing in the non-magnetic housing pipe 2 is charged and activated by the action of the magnetic field transmitted through the non-magnetic housing pipe 2 by the magnet 12 of the magnetic sliding body 10. For this reason, when the magnet filter 1 is attached to the fuel oil supply pipe, the combustion efficiency is improved or the scale of the pipe is prevented from adhering.

When the magnetizing process is continued, the magnetic field is always applied to the spiral guide member 7 so that iron powder or the like in the liquid to be treated is magnetized, and is joined to the spiral guide member 7 and deposited. The flow efficiency becomes worse. Therefore, the magnetic sliding body 10 is appropriately moved to the magnetic interrupting section y, and is magnetically shielded by the magnetic body 9 in the magnetic interrupting section y so that the magnetic force of the magnet 12 does not affect the inside of the non-magnetic housing pipe 2. Then, the magnetic field of the magnetization processing unit x is erased. As a result, the iron powder attached to the spiral guide member 7 is demagnetized, the bonding force with the spiral guide member 7 is lost, the iron powder flows down with the flow of the liquid to be treated, and the magnetized portion x is cleaned. . In addition, this magnetic sliding body 1
The movement conversion of 0 is also performed when oil or the like adheres between the outer peripheral surface of the non-magnetic housing pipe 2 and the inner surface of the magnet 12, and can cope with the case where the magnetic force of the magnet 12 is reduced by the oil film. .

[0013]

According to the present invention, as described above, the magnetic sliding body 10 can be slidably converted around the non-magnetic housing pipe 2 into a magnetization processing section x and a magnetic interruption section y. At the x position, a magnetic field can be applied to the liquid to be processed to perform a required magnetizing process, and when iron powder or the like is deposited on the spiral guide member 7 inside the liquid, the magnetic sliding body 10 is moved to the magnetic blocking portion y. Evacuate and demagnetize the iron powder by blocking the magnetic field,
This makes it possible to remove iron powder and the like along with the flow of the liquid to be treated, and also to remove an oil film adhered to the periphery of the non-magnetic housing pipe 2, so that dirt due to time use can be cleaned. There is an excellent effect that proper characteristics can always be produced.
