Description

The present invention relates to a fine mist generator suitable for salt formation by evaporating moisture by applying warm air or hot air to a fine mist of seawater, but can also be applied to fine atomization of liquids other than seawater.

The inventor of the present invention, in Japanese Patent No. 3250738, obtains salt crystals instantly by spraying warm air or hot air in a fine mist state by scattering seawater with a water wheel type impeller having a radial cavity. A salt production method was proposed. However, when a water wheel type impeller is rotated at a high speed, seawater is sucked together with outside air from the central seawater suction port by centrifugal force and released from each radial cavity. As it scatters, the fine mist collides with the outer protective wall and re-drops the water, reducing the vaporization efficiency. In addition, since the discharge air flow is too strong in this way, it interferes with pumping fine mist into the salt making chamber with warm air.

In order to solve such a problem, the inventor of the present invention proposed in Japanese Patent Application No. 2006-77655 a structure in which the high-speed rotating plate is a concave spherical surface and seawater is supplied to the center thereof. According to this structure, since there is no radial cavity that sucks and discharges outside air by centrifugal force, a strong discharge air flow can be suppressed. As a result, re-droplets on the protective wall and obstacles during hot air pumping are also eliminated.

However, as a problem that has been clarified in the subsequent practical application test, when seawater is diffused in the radial direction by centrifugal force, a bending force that stretches the concave spherical surface acts on the concave spherical shape during high-speed rotation. Cracks occur in the disc. This problem tends to occur near the mounting portion on the motor output shaft, where bending stress tends to concentrate. Further, innumerable guide grooves are radially formed to generate innumerable fine mists, but this processing is also difficult. Also in the case of a conventional water wheel type impeller, a device for making the mist more fine by increasing the number of blades on the outer peripheral side is complicated and difficult to manufacture.

By paying attention to such problems, a fine mist generator having a simple configuration that is robust and easy to manufacture can be realized, and a fine mist can be generated more effectively as shown in FIG. When liquid such as seawater SW supplied to the central portion C of the rotating disc 1 flows to the outer periphery along the disc inner surface 1i by centrifugal force, it collides with the stopper wall 2 provided at the outer peripheral position. In Japanese Patent Application No. 2006-183834, a method for generating the fine mist 3 by splashing and splashing was proposed.
Japanese Patent No. 3250738 Japanese Patent Application No. 2006-77655 Japanese Patent Application No. 2006-183834

However, also in this structure, bending stress is generated in the disk rotating at high speed by the energy when seawater collides with the stopper wall at the outer peripheral position, and this causes destruction. In particular, when the rotating disk is used upright, a significant problem is that the seawater does not disperse uniformly, so that the force that collides with the stopper wall at the outer peripheral position becomes uneven at each position. Vibration will cause bearing damage. The technical problem of the present invention pays attention to such problems, and realizes a fine mist generator with a simple configuration that can be easily manufactured with more safety, longer life, and no risk of damaging the rotating disk or motor bearing. There is to do.

The technical problem of the present invention is solved by the following means. In the first aspect of the present invention, when the liquid supplied to the central portion of the rotating disk rotating at high speed is stretched in a film shape along the surface of the rotating disk by centrifugal force and then shaken off from the outer periphery, The fine mist generation method is characterized in that the fine mist can be generated by colliding with and splashing on the rebound wall provided on the surface. In this way, when a liquid such as seawater supplied to the center of a rotating disk rotating at high speed is formed into a film by centrifugal force and shaken off from the outer periphery, it collides with the rebound wall provided on the outside. Therefore, the fine mist can be easily generated simply by providing a rebound wall at a position slightly away from the outer periphery of the rotating disk. As a result, the rotating disk and the rebound wall can be separated, and since no bending stress is generated, they are not damaged and have a long life, the configuration of the fine mist generating means is simplified, and manufacturing is facilitated. A flat plate is suitable for the rotating disk, but if it is small, a curved concave spherical shape or a tapered fine inclination is allowed.

Claim 2 is a structure in which the liquid supplied to the central portion of the rotating disk rotating at high speed is stretched in a film shape along the surface of the rotating disk by centrifugal force and then shaken off from the outer periphery. A bounce wall is provided in a ring shape at a position away from the outer periphery of the plate, and only the rotating disc can rotate at high speed independently of the bounce wall, is supplied to the center of the rotating disc, and flows in the outer circumferential direction by centrifugal force The fine mist generator is characterized in that the liquid shaken off from the outer periphery rebounds and collides with the wall and scatters. In this way, in the structure in which the liquid supplied to the central portion of the rotating disk rotating at high speed is stretched in a film shape along the rotating disk surface by centrifugal force, and then shaken off from the outer periphery, the rotating disk Since the rebound wall is provided in a ring shape at a position away from the outer periphery, only the rotating disk can be rotated at high speed independently of the rebound wall, and the configuration can be simplified and easily manufactured. In addition, the liquid supplied to the center of the rotating disk, flowing in a film shape along the rotating disk surface along the rotating disk surface by centrifugal force, and sprinkled off from the outer periphery collides with the rebound wall and scatters to form a fine mist. It becomes. A flat plate is sufficient for the rotating disk, but even if it is a concave spherical surface, a minute curvature is sufficient, and there is no possibility of causing bending stress that would be damaged by high-speed rotation. Instead of a minute concave spherical surface, a loose slope that slightly increases the outer peripheral side may be used.

According to a third aspect of the present invention, the rotating disk is made of a flat plate or a minute inclined or concave spherical plate, and the bounce wall is slightly inclined in the outward spreading direction. It is a fog generator. Thus, since the rotating disk is made of a flat plate, it is not necessary to have a concave curved surface as in the prior art, and bending stress that causes cracks and the like does not occur. In the case of a minute inclined or concave spherical disk, the curvature and gradient are almost zero and correspond to a gradient of 3 degrees or less, so bending stress that causes cracks and the like is also zero. close. In addition, since the rebound wall is slightly inclined in the outward spreading direction, the fine mist is rebounded to the front of the rotating disk. It can prevent the waste of fine mist.

4. The fine mist generator according to claim 2, wherein a radial vane plate is provided so as to surround a central portion of the rotating disk serving as a liquid inflow portion. It is. As described above, since the radial vane plate is provided so as to surround the central portion of the rotating disk that becomes the inflow portion of the liquid, when the rotating disk is used in an upright position, it is supplied to the center of the rotating disk. The liquid is immediately and effectively dispersed uniformly over the entire circumference by the rotation of the blades in the radial direction, and is then stretched into a film along the inner surface of the rotating disk. The liquid can be shaken off. Further, the problem that the liquid flows from the rotating disk and is wasted is also solved.

According to a fifth aspect of the present invention, a donut-shaped rotating disk is provided between the central portion and the outer periphery of the rotating disk, and a plurality of radial blades are provided between the donut-shaped plate and the rotating disk. 5. The fine mist generator according to claim 2, 3, or 4, wherein a small impeller part is formed and a plurality of short radial cavities are provided. In this way, by providing a donut-shaped rotating disk between the central portion and the outer periphery of the rotating disk, and by providing a plurality of radial blades between the donut-shaped plate and the rotating disk. A small impeller part is formed. As a result, a plurality of short and small radial cavities are formed, so that when the rotating disk is used upright, all the liquid supplied to the center of the rotating disk is effectively and evenly distributed over the entire circumference by the radial blades. Is done. Thereafter, the film reaches the outer peripheral end while being stretched in a film shape along the inner surface of the rotating disk outside the impeller part, is swung off toward the rebound wall, and collides to become a fine mist.

In addition, although it is small, there is a radial cavity with strong air suction and discharge by centrifugal force, so it is possible to accelerate the liquid supplied to the center of the rotating disk and violently collide with the rebound wall. Fog can be generated more effectively. In addition, since the radial cavity is provided between the central portion and the outer periphery of the rotating disk to ensure a sufficient film forming area, liquid is formed on the rotating disk surface between the impeller portion and the outer periphery of the rotating disk. The film can extend thinner and contribute to the generation of finer fog.

According to a sixth aspect of the present invention, the fine mist generator according to the fifth aspect is characterized in that the outer end of the radial blade is separated from the rotating disk. As described above, since the outer edge of the radial blade for forming the radial cavity is separated from the rotating disk, as described above, it is a region for extending the liquid film more thinly and uniformly. The distance between the impeller portion and the outer periphery of the rotating disk can be earned and extended.

In a seventh aspect of the present invention, the back plate provided on the back surface of the rotating disk via a gap is integrated with the bounce wall, according to any one of claims 2 to 6. This is a fine mist generator. Thus, since the back plate provided through the gap on the back surface of the rotating disc is integrated with the bounce wall, the rotating circle is caused by the air flow in the outer peripheral direction generated on the back surface of the rotating disc. A forward air pressure is generated between the outer periphery of the plate and the rebound wall. As a result, the liquid splattered from the outer periphery of the rotating disk or the mist that bounces off the bounce wall is pressurized forward and guided in front of the rotating disk. Is effectively guided to the front of the rotating disk and efficiently used for salt production.

Since the seawater collides with the rebound wall provided on the outer side of the rotating disk that rotates at a high speed as in claim 1 and scatters, the method of forming a fine mist is adopted. A fine mist can be easily generated by providing a rebound wall at a slightly separated position. As a result, the rotating disk and the rebound wall can be separated, and since no bending stress is generated, they are not damaged and have a long life, the configuration of the fine mist generating means is simplified, and manufacturing is facilitated.

In the structure in which the liquid supplied to the central portion of the rotating disk rotating at high speed is stretched in a film shape along the rotating disk surface by centrifugal force and then shaken off from the outer periphery, as in claim 2 Since the rebound wall is provided in a ring shape at a position away from the outer periphery of the rotating disk, only the rotating disk can be rotated at high speed independently from the rebounding wall, and the configuration is simple and can be easily manufactured. A flat plate is sufficient for the rotating disk, but even if it is a concave spherical surface, it has a very small curvature, so there is no fear of generating stress that can be damaged by high-speed rotation.

Since the rotating disk is a flat plate as in claim 3, it is not necessary to have a concave curved surface as in the prior art, and no bending stress that causes cracks or the like is generated. In the case of a minute inclined or concave spherical disk, the curvature and gradient are almost zero and correspond to a gradient of 3 degrees or less, so bending stress that causes cracks and the like is also zero. close. Moreover, since the bounce wall is slightly inclined in the outward spreading direction, the fine mist is bounced back to the front of the rotating disk, so that it detours to the motor output shaft side and adversely affects the motor bearing and lubrication means such as salt damage. It can prevent the waste of fine mist.

Since the radial blades are provided so as to surround the central part of the rotating disk serving as the liquid inflow portion as in claim 4, the rotating disk center is used when the rotating disk is used upright. The liquid supplied to is immediately and effectively dispersed uniformly around the entire circumference by the rotation of the blades in the radial direction, and then stretched into a film along the inner surface of the rotating disk. It becomes possible to shake off the film-like liquid uniformly. Moreover, the problem that the liquid flows down from the rotating disk and is wasted is also solved.

As in claim 5, a donut-shaped rotating disk is provided between the central portion and the outer periphery of the rotating disk, and a plurality of radial blades are set up between the donut-shaped plate and the rotating disk. Since a small impeller part is formed and a plurality of short radial cavities are provided, all the liquid supplied to the center of the rotating disk is used by the radial blades when the rotating disk is used upright. Effectively and evenly distributed over the entire circumference. Thereafter, the film reaches the outer peripheral end while being stretched in a film shape along the inner surface of the rotating disk outside the impeller part, is swung off toward the rebound wall, and collides to become a fine mist.

In addition, although it is small, there is a radial cavity with strong air suction and discharge by centrifugal force, so it is possible to accelerate the liquid supplied to the center of the rotating disk and violently collide with the rebound wall. Fog can be generated more effectively. Moreover, since the radial cavity is provided between the central portion and the outer periphery of the rotating disk to secure a film forming region, the liquid film is formed on the rotating disk surface between the impeller portion and the outer periphery of the rotating disk. It can extend thinner and contribute to the generation of finer fog.

Since the outer end of the radial blade for forming the radial cavity is separated from the rotating disk as in claim 6, the region for extending the liquid film more thinly and uniformly as described above The distance between the impeller portion and the outer periphery of the rotating disk can be earned and extended.

As in claim 7, since the back plate provided through the gap on the back surface of the rotating disk is integrated with the bounce wall, the air flow in the outer circumferential direction generated on the back surface of the rotating disk, A forward air pressure is generated between the outer circumference of the rotating disk and the rebound wall. As a result, the liquid shaken off from the outer peripheral edge of the rotating disk and the mist that bounced off the rebounding wall are pressed forward and guided in front of the rotating disk. The mist is effectively guided to the front of the rotating disk and used efficiently for salt production.

Next, an embodiment will be described using seawater as an example of how the fine mist generator according to the present invention is actually embodied. FIG. 2 is a view corresponding to the conventional structure shown in FIG. 1, and is a longitudinal sectional view at the center position of the rotating disk 1 that rotates at high speed for generating fine mist. The rotating disk 1 is a flat rotating disk made of stainless steel or other metal or synthetic resin, and a rebound wall 4 is provided at a position away from the outer peripheral edge thereof. Therefore, the rotating disk 1 is surrounded by the ring-shaped rebound wall 4. The output shaft 5 of the drive motor M is connected to the center of the back surface or the lower portion of the rotating disk 1.

Now, when the rotating disk 1 is rotated at a high speed of, for example, 10,000 revolutions per minute by the motor M while supplying the seawater SW to the central part C of the inner surface 1i of the rotating disk 1 by the seawater supply pipe, The supplied seawater SW is caused to flow to the outer peripheral side along the inner surface 1i of the rotating disk by centrifugal force. As a result, the film moves in the outer circumferential direction while being gradually stretched into a thin film. And finally, when it is shaken off from the outer peripheral edge of the rotating disk 1 and scattered outside, it immediately collides with the inner surface of the rebound wall 4 violently. As a result, it bounces back into a fine mist 6. Thus, since the rotating disk 1 is sufficient by a flat plate, manufacture is easy and there is no possibility of generating the bending stress by centrifugal force. However, it is possible to adopt a large spherical surface with a slight curvature that does not cause difficulty in manufacturing, or a minute gradient of 3 degrees or less. When the curvature or gradient is small, it can be easily formed by cutting or grinding one side of a flat plate.

The rebound wall 4 may be perpendicular to the inner surface 1i of the rotating disk 1, but may be slightly inclined outward as shown. When seawater collides with the rebound wall 4, some fine mist is generated on the back side of the rotating disk 1, but when the rotating disk 1 is a vertical type, the arrow a <b> 1 that is pumped from the back of the motor M It is sucked by hot air or hot air in the direction and guided in front of the rotating disk 1. That is, when the rotating disk 1 is used upright, hot air or hot air is pumped in the direction of the arrow a1 from the back of the motor M, so the air in the gap between the motor M and the rotating disk 1 is in the direction of the arrow a1. The air flow is in the direction of arrow a2. By this air flow, the fine mist generated on the back surface of the rotating disk 1 is sucked, merged with the air flow in the direction of the arrow a1, sent to the front of the rotating disk 1, and used for salt production.

When the rotating disk 1 is horizontal, the hot air or warm air in the salt-making chamber direction indicated by the arrow a3 is pumped in a direction parallel to the surface of the rotating disk 1, so that the gap H between the rotating disk 1 and the motor M is in the gap H. Since the air flow in the direction of the arrow a3 also flows in, the fine mist on the back side of the rotating disk 1 as described above is smoothly pumped toward the salt making chamber by this air flow. The ring-shaped rebound wall 4 is connected and held on the outer surface of the casing of the motor M by connecting bars B provided on the outer periphery thereof at intervals of 90 degrees, for example. The connecting bar B is fixed to the outer surface of the rebound wall 4 via the spacer S, but the spacer S is not always necessary.

FIG. 3 is an enlarged horizontal sectional view showing the right rebound wall 4 side of FIG. 2, and is inclined outward by an angle α with respect to a chain line perpendicular to the rotating disk 1. Therefore, the rotating disk 1 is open to the front side. When the rotating disk 1 is rotated at a high speed, the seawater supplied to the central part of the rotating disk is caused to flow to the outer peripheral side as indicated by an arrow a4 along the inner surface 1i of the rotating disk by centrifugal force, and becomes thin like a film. While spreading. Then, immediately after being finally swung off from the outer peripheral edge and scattered outside, it collides with the outer rebound wall 4 and bounces back to become a fine droplet, and a fine mist 6 is generated.

In this case, since the rebound wall 4 is inclined outward by an angle α, most of the rebounded fine mist 6 is rebounded to the front surface side of the rotating disk 1 and subsequently hot air or hot air in the direction of the arrow a1. Is pumped in the direction of the salt making chamber Therefore, by tilting the rebound wall 4, most of the rebounded fine mist 6 can be effectively collected forward, and the generated fine mist is less wasteful. In addition, the problem that the fine mist bypasses the motor shaft 5 and damages the motor bearing can be prevented.

The rotating disk 1 as described above is different from the conventional turbine structure in which a large number of radial cavities that generate a discharge air flow continue to the outer peripheral edge. (1) In the central part of the rotating disk 1 that rotates at high speed. Since suction pressure due to centrifugal force is not generated and the fine mist is not affected by the discharge air flow, the fine mist does not scatter far and collides with a protective wall to prevent the danger caused by the breakage of the rotating plate. To prevent re-dropping. (2) In this way, since the scattering force of the fine mist from the outer periphery is not too strong, the hot air blowing force in the direction of the arrow a1 from the back can be suppressed, and the scattering of seawater fine mist to the motor output shaft 5 side Detours are also reduced.

When the output shaft 5 of the motor M in FIG. 2 is leveled and the rotating disk 1 is used upright, the seawater SW from the seawater supply pipe flows down from the front center of the rotating disk 1 rotating at high speed and is useless. Therefore, the supplied seawater SW as a whole may not be smoothly used as the fine mist 6. Therefore, as shown in FIGS. 4 and 5, it is effective to provide, for example, six radial (or radial) blades f near the central portion C of the front surface 1 i of the rotating disk 1.

Now, when the rotating disc 1 rotates at high speed, the seawater SW supplied from the supply pipe as shown in FIG. 2 to the central portion C of the rotating disc is dispersed all around by the radial blades f ... rotating at high speed. Therefore, in a state of being uniformly distributed over the entire inner surface of the rotating disk 1i, it is made to flow toward the outer periphery while being gradually stretched into a thin film, and is swung off from the outer periphery. Next, as described above, it collides with the rebound wall 4 and rebounds to form a fine mist. Thus, it is not necessary to provide a large number of the radial blades f... Provided so as to surround the inflow portion of the seawater SW near the central portion C of the rotating disk 1, and may be within about 10 sheets. A simple rectangular shape is sufficient.

When the rotating disk 1 is set up vertically, as shown by a chain line in FIGS. 2 and 3, a back panel P is provided on the back part of the rotating disk 1 through a gap h, and the outer peripheral part of the rotating disk 1 rebounds. It is connected and integrated with the back end of the wall 4. When the rotating disk 1 rotates at a high speed, an air flow in the outer peripheral direction is also generated on the back surface due to centrifugal force. Therefore, the gap h between the rear plate P and the rotating disk 1 is filled with the air flow in the outer peripheral direction. . Due to the air flow, a forward air pressure is generated in the gap between the outer periphery of the rotating disk 1 and the rebound wall 4.

As a result, the liquid shaken off from the outer peripheral edge of the rotating disk 1 and the fine mist 6 generated by rebounding from the rebounding wall 4 are pressurized forward (in the direction of the arrow a1) and rotated. It is pumped forward of the disk 1. And it is attracted | sucked by the warm air and hot air of the arrow a1 direction which were pumped from the back part of the motor M, is effectively sent ahead of the rotating disc 1, and is provided for salt production. When a radial vane f as shown in FIG. 4 is provided on the back surface of the rotating disk 1 and the air is blown in the outer circumferential direction, the air pressure in the outer circumferential direction in the gap h is also increased. In addition, air can be supplied to the central portion C of the radial blades f from between the connecting bars B and B with compressed air.

In the case of a structure in which seawater collides with the rebound wall 4 on the outside of the rotating disk 1 as in the present invention, a conventional water wheel type impeller structure can be used in combination to increase the collision energy. FIG. 5 is an embodiment in which a small impeller unit 7 is provided instead of the radial blades f of FIG. 4, (1) is a plan view, and (2) is an AA cross-sectional view. Reference numeral 8 denotes a radial blade, which is slightly curved in a direction in which the acceleration force of the seawater flow due to centrifugal force increases. In order to sandwich and fix these arc-shaped radial blades 8 in a state of standing between the rotary disks 1, donut-shaped disks 9 are overlapped and fixed on the radial blades 8. It is. Needless to say, each radial blade 8 is also fixed to the rotating disk 1 side. According to this structure, radial cavities 10 are formed between the arcuate blades 8 between the doughnut-shaped plate 9 having a width W and the rotating disc 1.

As a result, when the rotating disk 1 is rotated at a high speed while standing as shown in FIG. 4, the seawater supplied to the rotating disk central portion C is rotated on the rotating disk inner surface 1 i by the high-speed rotation of the radial blades 8. It is accelerated toward the rebound wall 4 while being uniformly distributed over the entire circumference. Moreover, since the radial cavities 10 ... rotate at high speed, seawater is sucked from the central portion C of the rotating disk together with air by centrifugal force and released in the radial direction on the same principle as that of a conventional high speed rotating disk of the conventional watermill type. In the film-forming region D of the inner surface 1i of the rotating disk, the film is stretched by a centrifugal force to gradually become a thin film. It becomes a fine mist. If the fine mist stagnates around the front surface of the rotating disk 1, it is sucked together with seawater by the centrifugal force of the radial cavities 10 ..., so that stagnation of the fine mist is prevented.

As described above, because the seawater SW is sucked together with the air, it is necessary to arrange the inner ends of the radial blades 8 near the center C of the rotating disk 1 to which the seawater SW is supplied. It is desirable that the outer peripheral position of the doughnut-shaped plate 9 is arranged closer to the central portion C than the half position of the radius of the rotating disk 1. That is, it is desirable that the radius of the doughnut-shaped plate 9 is made smaller than ½ of the radius of the rotating disk 1 and the impeller portion 7 is downsized. As a result, a film-forming region D for making seawater into a thin film can be secured between the small impeller portion 7 and the outer peripheral edge of the rotating disk.

As shown in FIG. 5 (2), each radial blade 8... Has a gap G formed by partially cutting the rotating disk 1 side. Thus, by providing the gap G near the outer periphery of the doughnut-shaped plate 9, the film formation region D on the inner surface 1i of the rotating disk is expanded toward the central portion C, thereby making the seawater film thinner and thinner. The mist can be made finer. Alternatively, the rotating disk 1 can be further downsized. The outer diameter of the rotating disk 1 is about 25 to 35 cm and the thickness is about 2 to 4 mm, and the width W of the rebound wall 4 can be about 1 to 2 cm or less. The gap between the outer periphery of the rotating disk 1 and the rebound wall 4 and the gap between the back surface of the rotating disk 1 and the back plate P are each preferably about 1 to 5 mm. However, it is not limited to these dimensions.

In the above embodiment, the mounting posture such as the angle and the inclination when the rotating disk 1 is used is arbitrary. In addition, although the example which salt-minates seawater was demonstrated, it cannot be overemphasized that the thought of this invention is applicable also to the fine atomization of liquids other than seawater.

As described above, the fine mist generator of the present invention is simply provided with an independent rebound wall 4 in the form of a ring outside the outer peripheral edge of the rotating disk, so that the structure is simple and can be easily manufactured and rotated. External force that damages the disc does not work. Moreover, it is possible to effectively generate fine mist.

It is a longitudinal cross-sectional view in the center position of the conventional high-speed rotation disc. It is a horizontal sectional view of the center position of the high-speed rotating disk of the fine mist generator according to the present invention. It is the horizontal sectional view which expanded and showed the bounce wall side of the right side of FIG. It is a perspective view of an embodiment which provided a radial vane near the central part of the front surface of a rotating disk. It is embodiment which provided the small impeller part in the intermediate position of the radial direction of a rotating disc, (1) is a top view, (2) is AA sectional drawing.
