Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for applying powder or granular materials under various gas atmosphere conditions.
Plasma ions are irradiated under various pressure and temperature conditions to cause a physical or chemical reaction on the surface, activating the surface and imparting lipophilicity, hydrophilicity, or philophilicity. Alternatively, the present invention relates to an activation device that improves dispersibility.

FIG. 1 is a sectional view for explaining the principle of an embodiment of the present invention. Electrodes 1 (corresponding to the excitation electrode) and 2 (corresponding to the counter electrode) have an extent perpendicular to the plane of the paper.

Dielectric particles 3 are packed between both electrodes 1 and 2. The shape of each particle of the granules 3 can be selected from various shapes depending on the conditions, such as spherical, hook-shaped, fiber-shaped, or rod-shaped.

On the other hand, the output of an AC high voltage power source 4 is applied to the electrodes 1 and 2, respectively. When a voltage is applied to both electrodes 1 and 2, plasma is generated via the surface of the particles 3. In this case, since the dielectric material is composed of particles 3, the surface area is extremely large, resulting in an extremely large amount of plasma being generated.

FIG. 2 shows an example in which two types of particles 5 and 6 having different dielectric constants are filled in place of the particles 3 in FIG. 1. In this case, the plasma ion fear has the advantage of producing a special density phenomenon compared to that shown in FIG.

In both FIGS. 1 and 2, sheets 8 and 9 may be provided on the inner surfaces of the electrodes 1 and 2, as shown in FIG. 3, which will be described below.

FIG. 3 shows an example in which metallic or conductive particles 7 are mixed into the particles 3 in FIG. 1. In this case, the mixed particles 7 have the advantage of further promoting the generation of plasma ions. In this case, the surfaces of the electrodes may be covered with dielectric sheets 8 and 9, respectively.

In FIG. 4, a power source 4 is applied between the electrode 12 (corresponding to the excitation electrode) via the electrode 10 (corresponding to the body-facing electrode) and the dielectric sheet 11, and the electrode 12 and the sheet 11. It is a structure that generates plasma on the surface of the Furthermore, the structure is such that an AC high voltage power source 14 is applied between the electrode 12 and the electrode 13 (corresponding to the counter electrode) via the grains 3. This feature allows the plasma region generated between each particle of the grain body 3 to be
This can be controlled by

The feature of FIG. 5 is that the power source 14 is a DC high voltage power source 15, and plasma ions of positive or negative polarity are arbitrarily generated.

In FIGS. 4 and 6, the granules 5 and 6 or the granules 3 and 7 shown in FIGS. 2 and 3 can also be used.

In Figure 6, both electrodes l( 2 (corresponding to the excitation electrode) and 2 (corresponding to the counter electrode) are facing each other.

Since plasma ions are generated via the space in the shell 16, the plasma ions are extremely abundant. Further, as in FIG. 3, it is also possible to include metal grains in the shell 16.

What all of the above have in common is that the surface of the dielectric material is extremely large in order to generate abundant plasma ions.

Furthermore, it has been confirmed that each of the above-mentioned sides simultaneously generates abundant ozone as well as plasma ions, and the ozone has the advantage that it can be used for various purposes such as disinfection and sterilization.

FIG. 7 shows a state in which powder or granule material 17 to be activated is adhered to the surface of the granule material 3 of the example shown in FIG. 1. As a result, the powder and granular material 17 is deagglomerated and irradiated with abundant plasma ions, so that the activation efficiency is extremely improved. In general, the finer the powder 17 is, the more likely it is to adhere to the surfaces of the electrodes 1 and 20 and to agglomerate. If adhesion or aggregation occurs, the efficiency of activation will decrease, resulting in an extremely unfavorable situation. As shown in FIG. 7, when the granular material 17 is attached to the surface of the granular material 3, the granular material 17 is attached to the surface of the electrodes 1 and 20.
The phenomenon of particles 7 adhering to the electrodes 1 and 20 becomes extremely rare, and there is no aggregation, and if the particles 3 move at the same time, the particles 3 will scrape off the particles 17 that have adhered to the surfaces of both electrodes 1 and 20. , powder 17 on the surfaces of both electrodes l and 20
It is possible to prevent the adhesion of Even if the powder 17 is a fine powder that is difficult to handle, the mixture of the simultaneously crushed granules 3 and the powder 17 has the properties of a coarse powder that is easy to handle, and the handling of the mixture is difficult. This feature makes it extremely easy to use. This gives rise to the advantage that activation of fine powder can be carried out extremely easily.

Of course, in this case, it is necessary to separate the mixture after the activation treatment into the granules 3 and the powder 17, but this can be done easily by using a classifier or by pouring them into a solvent. It is. In FIGS. 2 and 3, the powder 17 can be handled in the same manner as in FIG. 7.

FIG. 8 shows the particles 19 of the powder material 17 infiltrated into the space of the sheet 16, and
This shows a state in which particles 19 are attached to the surface of. If the sheet 16 is installed between both electrodes 1 and 20, the powder 1
Particles 19 of No. 7 will be irradiated with extremely abundant plasma ions, resulting in the advantage that the activation process will be performed extremely efficiently.

At the same time, as the powder 17 becomes finer, handling problems and adhesion problems occur as explained in FIG.
Since the problem is contained within 6, it can be easily solved. If the sheath H6 is inserted into both electrodes 1 and 2 and moved, the particles 19 contained therein will also move at the same time, making it easy to handle and preventing adhesion to the surfaces of electrodes 1 and 2. Great benefits accrue. Of course, in this case, it is necessary to carry out an operation such that the powder 17 is included in the sea H6, and it is also necessary to separate the powder 17 from the sea H6 after activation, but this requires the use of solvents, etc. It turns out that it is extremely easy to use.

FIG. 9 shows a structure in which a needle-shaped electrode 2° (corresponding to an excitation electrode) is provided in addition to the electrode 1 shown in FIG. This has the advantage that the plasma area is further enhanced.

Such electrode structures are shown in Figs. 2, 3, 4, and 5.
It can be similarly used for figures etc. It is also known that each of the above devices generates abundant ozone, so they can also be used as ozone generators.

Hereinafter, how the present invention can be applied to an activation device, an ozone generator, etc. having great advantages or features will be explained by way of application examples.

FIG. 1O is an example of an activation device used in a belt feeder, which is a type of feeder. That is, in the hopper 21, for example, glass beads are mixed with the powder to be activated.
Mixed powder 22 is stored. The powder can be activated by discharging it with a dielectric belt 23 and passing it between the electrodes 1 and 20 having the structure shown in FIG. 1, which have been provided in advance. As a result, the powder does not aggregate and is less likely to adhere to the belt 23 or the like, thereby increasing the efficiency of activation.

Moreover, since it is exposed to abundant ozone, it can also be subjected to treatments such as sterilization.

FIG. 11 shows an application example of an activation device using a belt feeder using the belt 26 having the structure shown in FIG. The powder to be activated 24 enters and disperses into the belt 26 by the discharge presser 25, and is subjected to an activation action in the process of passing between the electrodes 1 and 20. Note that the powder 24 in the belt 26
5 is brushed off by the air jet 27 and sent to the next process via the hopper 28.

FIG. 12 is an application example of an activation device using a screw feeder to which the principle of FIG. 1, FIG. 2, or FIG. 3 is applied. That is, the screw 29 corresponding to the electrode 1 and the electrode 2
A high voltage is applied from the power source 4 to the tube 3° corresponding to the angle.

A mixed powder 22 is stored in the hopper 21 and is discharged by a screw 29 driven by a motor 31.

During this process, the powder to be activated is irradiated with abundant plasma ions and is activated. Even if the powder is fine, the mixed powder 22 has properties similar to coarse powder and is extremely smooth to handle.

FIG. 13 is an example of an activation device applied to an electromagnetic feeder. That is, a high voltage is applied to the electrodes 32 and 33 from the power source 4, and the mixed powder 22 is exposed to abundant plasma ion irradiation while passing between them. Also, for the electrodes 32 and 33, FIGS.
It is also possible to apply the structure shown in FIG. In this case, there is an advantage that a vibration feeder, which is not suitable for fine powder, can be used as an activation device for fine powder.

Although there are various kinds of fine powder feeders, an activation device for any of them can be constructed using the present invention in the same manner as described above.

FIG. 14 is an example of an application related to a transportation device. A high voltage is applied from the power source 4 to the chain 34 and the casing 35 housing it. The inner surface of the casing is lined with a dielectric sheet 36, which has the advantage that the mixed powder 22 handled by the chain 34 can be activated during the process of being transferred within this chain conveyor. Of course, Fig. 14 shows a part of a long chain conveyor, but 1. It is not necessary to provide such a device over the entire length of the chain conveyor, and it is also possible to construct a part of it as shown in FIG. 14.

Various other types of shaft feeding devices are used, and the present invention can be similarly applied to any of them.

FIG. 15 shows an example in which the present invention is applied to a mixer and used as an activation device. The principle of Figure 1 or Figure 2 is applied. In other words, the mixer body 37 and the mixing blades 38 have
A high voltage is applied from the power source 4. Power is supplied to the mixing blade 38 via a brush mechanism 39 and an insulating bushing 40. While the mixed powder 22 is subjected to a mixing and agitating action together with other powders and granules that have been added, when uniform mixing is achieved, the mixed powder 22 is simultaneously subjected to an activating action. They will also be exposed to abundant ozone.

In this case, it is also easy to adopt the electrode structure shown in FIG. 4, FIG. 5, or FIG. 9.

FIG. 16 shows an application example in which the stirring blade 42 of the stirring 4141 and the storage tank 43 are configured to correspond to the electrodes 1 and 2. Power is supplied to the stirring blade 42 via a brush mechanism 44 .

In addition to the dielectric granules 3, a predetermined amount of several kinds of powder and granular materials to be mixed are placed inside the storage tank 43, and are subjected to a stirring and mixing action by the stirring blade 42, and at the same time are subjected to an activation action. This has the advantage of significantly shortening the process. In this case, it is also possible to adopt electrode configurations corresponding to FIGS. 4.5 and 9 of the invention, if necessary.

Various other mixers are commercially available and are in use, but all of them can be given the function of an activator using the same method.

FIG. 14 is an example of application of the present invention to a crusher. In this case, there is an advantage that the particles made of the powder dielectric to be activated are activated at the same time as they are crushed and mixed. The figure shows a pulverizer for fine grinding. That is, the rotary blade 45 for crushing and the body 46 correspond to the electrodes 1 and 2. Power is supplied to the rotating blade 45 via a brush mechanism 44.

Further, the electrode configurations shown in FIGS. 4.5 and 9 can also be easily adopted.

Various types of fine pulverizers are commercially available and used, but the present invention can be similarly applied to any of them, and the advantage is that they can be further provided with a function as an activator or an ozone treatment device.

FIG. 18 is an example of application of the present invention to a fluidized bed.

That is, the electrode 47 and the body 48 are configured to correspond to the electrode 1 and the electrode 2.

The mixed powder 22 introduced into the body is subjected to a fluidizing action by the gas ejected from the filter 49 described below, and
It will have an activating effect. Alternatively, if the ejected gas is air or oxygen gas, you will be exposed to abundant ozone. This has the advantage that it is possible to perform various physical and chemical treatments in the fluidized bed and at the same time to impart effects such as activation.

FIG. 19 is an application example in which the method shown in FIG. 4 of the present invention is applied to a container. The container 50 is configured to rotate via a motor 51 and a bearing 52. The blade 53 is fixed by a leaf spring 54. The output of the power source 4 is applied to an electrode 58 (corresponding to the electrode 12 in FIG. 4) via a plush mechanism 55, a contact ring 56, and an insulating bush 57. At the same time, the electrode 61
(corresponding to the electrode 10 in FIG. 4). Container 5
The inner surface of 0 is lined with a dielectric lining 62. On the other hand, the output of the power source 14 is applied to the blade 53 (corresponding to the electrode 13 in FIG. 4) via the support 63, the leaf spring 54, and the shaft 64. At the same time, a voltage is also applied to the electrode 58.

As a result, the mixed powder 22 placed in the container 50 is activated. On the other hand, if the power source 15 shown in FIG. 5 is used in place of the power source 14, it is possible to activate the plasma ions of the desired positive or negative electrode.

In this case, it has been revealed that even if the powder to be activated is a fine powder, no problem of aggregation or adhesion occurs, and moreover, a remarkable activation effect can be achieved in a shorter time.

In addition, it can also be used in a plating machine or kneader depending on the case.

As shown in the various application examples above, it can be seen that the present invention has extremely diverse application fields as an activation device. At the same time, it can be seen that the fields of application that utilize the abundant ozone generated are extremely wide.
