Description

[Detailed description of the device] This device is designed to improve the liquid quality, prevent the formation of scale and corrosion, and at the same time separate and collect dissolved solids in the liquid at an early stage. Regarding a liquid quality improvement device.

In the prior art, various liquid treatment devices have been devised for the purpose of improving liquid quality. Particularly, in industrial liquid processing equipment, processing equipment using magnetic lines of force is often used because it is easy to operate and can perform continuous processing. These devices are covered by U.S. Patent No. 2825464.
No. 3951807, and in Japan there is also a device called Special Publication No. 1972-21845.

The device disclosed in US Pat. No. 2,825,464 consists of a long cylindrical magnetic processing section and a bulb-shaped dispersion section connected to the magnetic processing section. In other words, the magnetic processing unit inserts and fixes a thin-walled long cylindrical inner box made of a non-magnetic material into a long cylindrical outer box made of a magnetic material concentrically with spaced apart intervals. Insert three permanent magnets with the same poles next to each other, close both ends, and introduce water in the axial direction across the width of the gap between the inner box and outer cylinder to perform magnetic treatment between them. is forming. In addition, the dispersion section is provided with a dispersion member perpendicular to the flow direction of the introduced water in the bulb-shaped outer box, and a notch or groove is formed in the dispersion member at the position where the introduced water collides, so that the collided introduced water is removed. It is formed so that the flow is divided in the direction of the inner wall surface of the bulb-shaped outer box, and then converged into an outflow pipe and flows out. In this method, the introduced water collides with the dispersion member in order to disperse it, so the introduced water is turbulent in this part, resulting in large fluid resistance.At the same time, the flow velocity in the magnetic processing section is insufficient, and the magnetic processing effect is small, and the dispersion section Depending on the dispersion flow, the separation effect of the precipitated solids cannot be expected.

The invention of US Patent No. 3951807 is an improvement on the invention of US Patent No. 2825464,
It is made to pass through a stronger magnetic field,
A cylindrical outer box made of a ferromagnetic material is provided with a cylindrical inner box made of a non-magnetic material arranged concentrically at spaced intervals, and a rod-shaped permanent magnet is sealed in the inner box. The magnet is formed so as to generate lines of magnetic force perpendicular to the axis between the rod-shaped permanent magnet and the outer case. The passing fluid is configured to flow along the axis within the spaced apart space between the inner surface of the outer box and the outer surface of the inner box, and to cut the magnetic field lines at right angles. However, even this idea has the problem that the fluid resistance acting on the passing fluid introduced from one end of the cylinder is large, making it impossible to obtain a sufficient flow velocity. Therefore, even if the fluid treatment device can be downsized,
Treatment effects that depend on fluid velocity cannot be expected to be very effective.

Furthermore, the invention of Japanese Patent Publication No. 43-21845 is designed to increase the strength of the magnetic field and the speed of the fluid passing through this part in order to enhance the effect of improving the liquid quality. That is, a protrusion is provided in the fluid passage to form the fluid passage exactly like a ventilate, and at the same time, opposite walls of the protrusion are formed with opposite polarity so that a high-density magnetic flux is generated in the protrusion. It is formed with two permanent magnets, each end of which has a polarity opposite to that of the protrusion. This method has a problem in that it is difficult to manufacture a magnet that creates a magnetic field at the same time as the fluid passage. In addition, as shown in Figure 1, a fluid passage is formed inside the magnet body that forms the magnetic field, and the direction of the fluid flow is specified within this fluid passage to effectively cut the magnetic flux. Some designs have built-in screws for use. Even if the processing equipment can be made smaller,
It has the drawback of high fluid resistance and inability to obtain sufficient flow velocity. This idea is similar to that seen in conventional examples.
It is an object of the present invention to provide a liquid quality improving device that eliminates the drawbacks and has a function of separating and collecting precipitated scale while obtaining a sufficient flow rate.

This invention will be explained in detail based on illustrated embodiments.

FIG. 2 is an explanatory longitudinal cross-sectional view of the liquid quality improvement device according to this invention. In the figure, 1 is a processing tank. Processing tank 1
is made of steel material, is formed into a cylindrical shape with a uniform circular cross section, and has spherical bottoms at both ends, separating the main body part 2 and the lower tank part 3 of the processing tank 1, A flange portion 4 is provided and formed to be connected so that internal repair can be easily performed. 5 is a liquid introduction pipe. The liquid introduction pipe 5 is provided on the upper wall of the processing tank 1,
It is provided so that the introduced liquid flows in the tangential direction of the inner wall surface of the main body part 2. In other words, the introduced liquid is made to rotate within the main body portion 2. 6 is an outflow pipe. The outflow pipe 6 is provided at the bottom of the processing tank 1 so as to have its axis parallel to the axis of the main body 2 . The size of the outflow pipe 6 is determined by the quality of the liquid to be treated, but the insertion height of the outflow pipe 6 into the main body 2 is such that the opening edge is located below the opening position of the fluid introduction pipe 5. Form it like this. 7 is an aperture plate. The aperture plate 7 is formed by fixing a ring-shaped flat plate made of steel to the inner surface of the lower tank portion 3 of the processing tank 1 at right angles to the axis of the processing tank 1, and providing a discharge pipe 8 on the inner peripheral edge of the center. The opening of the discharge pipe 8 is sealed with a blind plate 9, and through-cut holes 10 are formed in the circumferential wall of the discharge pipe 8 at equal intervals. The total area of the through notch holes 10, the area of each notch, and its position are determined depending on the quality of the liquid to be treated. 11 is a magnet body that forms a magnetic field.

As shown in FIG. 3, the magnet body 11 is constructed by inserting a plurality of rod-shaped permanent magnets 13, 14, 15, etc. into a thin-walled cylindrical housing tube 12 made of a non-magnetic material, and having both edges covered with a non-magnetic material. It is sealed with a blind plate 17 formed by. In this case, the blind plate 17 is the storage cylinder 1
It is formed so as to be fixed at a position slightly inside the opening edge of No. 2. Furthermore, as shown in FIG. The edge of the opening contacts the diaphragm plate 7 to prevent corrosion due to contact between dissimilar metals. Further, the rod-shaped permanent magnets 13, 14, and 15 to be inserted are formed so that both adjacent ends thereof have the same polarity. In other words, the bar-shaped permanent magnets 14 provided adjacent to the bar-shaped permanent magnets 13 are formed so as to face each other with the same polarity, and at the same time are provided so as to be in contact with each other with a spacer 16 formed of a non-magnetic material interposed therebetween. Furthermore, a plurality of rod-shaped permanent magnets 13,
A plurality of magnet bodies 11 each having magnets 14, 15, . . . are provided in a processing tank 1. The magnet body 11 is fixed with one end thereof in contact with one surface of the aperture plate 7 of the processing tank 1, and the other end thereof is a pipe header plate 18 fixed horizontally above the liquid introduction pipe 5 of the main body 2. Fix it. Further, the plurality of magnet bodies 11 are arranged at appropriate intervals within a range that is slightly larger than the diameter of the discharge pipe 8 and outflow pipe 6 of the processing tank 1 and has a radius corresponding to approximately 70% of the inner radius of the main body 2. Place them with a close distance between them. In this case, it is desirable to arrange them axially symmetrically with respect to the axis of the processing tank 1 as an axis of symmetry, or, as shown in FIG. 4, to provide them in plane-symmetrical positions with a plane containing the axis as a plane of symmetry. Further, the header plate 18 is provided with through holes to the extent possible in addition to insertion holes into which the necessary number of magnet bodies 11 are inserted and locked. Reference numeral 19 denotes an air flow pipe for venting and purging air inside the processing tank 1. The air flow pipe 19 is provided at a high location near the outflow pipe 6 of the processing tank 1, and is normally closed with a plug or a plug. 20 is a sight glass. sight glass 2
0 is provided in the lower tank part 3 of the processing tank 1 so that the direct view position is located at the through-cut hole 10 of the discharge pipe 8.

Thus, the processing tank 1 has an outflow pipe 6 directed vertically upward, and the processing liquid is introduced from the liquid introduction pipe 5. The air in the processing tank 1 is extracted by an air flow pipe 19 so that no residual air bubbles remain. The introduced liquid descends while swirling around the axis of the processing tank 1, changes direction within the aperture plate 7 and the discharge pipe 8 at the center of the aperture plate 7, and becomes an upward swirling flow near the center of the outlet pipe 8. flows out from. Just reduce the flow in the cyclone separator. Therefore, the downward swirling flow cuts the lines of magnetic force formed by the magnets 11 that are mainly arranged outside the axis of the processing tank 1 among the plurality of magnets 11 provided in the processing tank 1, and the downward swirling flow is caused to rise. The swirling flow rises while mainly cutting the lines of magnetic force formed by the magnet body 11 placed inside. Both the upward swirling flow and the downward swirling flow are controlled by the magnet body 11 to control the velocity distribution within the processing tank 1.
In particular, although the maximum velocity is reduced, it is still possible to obtain a flow velocity that is extremely high compared to the parallel flow in a magnetic field shown in the prior art or the flow velocity through a screw that specifies the direction of liquid flow. Experiments have also confirmed that a flow rate approximately 10 times faster than the conventional example can be obtained. In addition, due to the downward swirling flow, solid particles in the liquid or precipitated dissolved solids are separated and descend, deposited at the bottom of the lower tank section 3 through the through notch 10 of the discharge pipe 8, and flowed out from the drain valve 22. be done. The deposition status of the solid particles and the precipitated dissolved solids is confirmed by visually observing the concentration level of the bottom liquid in the lower tank section 3 using the sight glass 20. In addition, simple cleaning of the inside of the processing tank 1 is carried out by introducing air through the air flow pipe 19, pressurizing the inside of the processing tank 1, and blowing out the pressurized air from the drain valve 22.

This device is constructed as claimed in the utility model registration claim based on the above-mentioned embodiment, so that the liquid introduced from the liquid introduction tube becomes a rotating flow and descends while cutting the lines of magnetic force formed by the magnet at right angles. At the same time, the upward rotational flow in the center can also cut the lines of magnetic force at right angles. The velocity of the fluid cutting through these lines of magnetic force creates a vortex, which is faster than any of the conventional examples and can reach speeds of about 10 meters per second.

Furthermore, the rotational flow allows separation and removal of the precipitated solids at the same time. In other words, the magnetic processing effect of the permanent magnet magnetizes the dissolved solids, allowing them to be precipitated and coagulated early, making it possible to separate and remove fine impurities that are too large to be separated and removed using a rotary separator alone. . Furthermore, since the opening edge of the magnet comes into contact with the aperture plate via the insulating socket, it is also possible to prevent corrosion due to contact between dissimilar metals. Furthermore, since an air flow pipe is provided, the air inside the processing tank can be easily vented and cleaned. In addition, a sight glass is installed in the lower tank, making it easy to visually check the processing status. Furthermore, the entire device is simple and the discharge pressure of a cooling water pump or the like can be used as is, making it possible to provide a practical liquid quality improving device.
