[0002]

2. Description of the Related Art Conventionally, an air purifier has only used an air filter using a filter cloth or the like.
In addition, even though an antibacterial agent may be used for treating water or the like, there is no known idea of using a magnetic material in combination.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of achieving sterilization of air, water, etc. by extremely simple means.

[0004]

A first aspect of the present invention is that a magnetic material and a germicidal material are disposed at any place in an apparatus to which a processing liquid or a processing gas can come into contact. The present invention relates to a processing gas sterilizer. That is, the basis of the present invention is that the treatment liquid or the treatment gas is simultaneously brought into contact with the magnetic force and the sterilizing material.

[0005] A second aspect of the present invention is that the magnetic material constitutes an arbitrary portion of the device, and the germicidal material forms at least a surface layer of each portion constituting the device. And a sterilizing apparatus for the processing liquid or the processing gas described above. The term "site" refers to each component of the apparatus, such as a storage tank, a pipe for supplying a processing liquid or a processing gas thereto, and a pipe for discharging the processing liquid or the processing gas from the storage tank. The magnetic material includes a case where the magnetic material is attached to the surface of a tank or a pipe.

A third aspect of the present invention is the sterilization of the processing liquid or the processing gas according to claim 2, wherein the part is at least one of a part through which the processing liquid or the processing gas passes, a part where the processing liquid or the processing gas stays, and an insert. Related to the device. The site through which the processing liquid or the processing gas passes is, for example, a pipe,
The stagnant portion is a tank or a tank, and the insert means a filter such as a wire mesh, a rod-like material, a plate-like material, or the like that can be inserted into a pipe or a tank.

A fourth aspect of the present invention is that the insert is an insert using a magnetic material, an insert in which the surface of a magnetic material is coated with a bactericidal material, and an insert in which the germicidal material is coated. And a sterilizing apparatus for the processing liquid or the processing gas described above.

[0008] A fifth aspect of the present invention is that the insert has 10-20
The sterilization apparatus according to claim 3 or 4, further comprising a vibration means for giving a vibration of 0 Hz.

A sixth aspect of the present invention relates to a sterilizing apparatus for processing liquid or processing gas according to any one of claims 1 to 5, further comprising a stirring means.

A seventh aspect of the present invention relates to an apparatus for sterilizing a processing liquid or a processing gas according to claim 6, wherein said stirring means is a vibration stirring apparatus.

As the magnetic material in the present invention, a permanent magnet (hard magnetic material) can be used, an electromagnet can be used, and in some cases, a soft magnetic material can be used. Examples of the hard magnetic material include a ferrite magnetic material, a rare earth magnetic material, and a magnetic steel. Specific examples include an alnico magnet, a samarium cobalt magnet, a neodymium magnet, an iron magnet, and a boron magnet. In the case of a soft magnetic material, a coil may be wound around the material, a current may be passed through the material to give a necessary magnetic force to the soft magnetic material according to the principle of an electromagnet, and the material may be used. Examples of the soft magnetic material include soft iron, silicon steel, and permalloy. When magnetism is provided by the electromagnet principle, the polarity is changed from (1) plus to minus, (2) minus to plus, (3) all to minus, (4) all to plus, or (5). For example, certain metal parts can be selectively given plus and minus, and other particular metal parts can be given plus and minus selectively. Further, as these magnetic materials, a flexible thin plate magnet described in Japanese Utility Model Publication No. 53-21438 can be used, and a composition in which magnetic material particles are dispersed in rubber or plastics can also be used.
The strength of the magnetic force is preferably at least 500 Oe.

[0012] Since the magnetic material is a material which is relatively difficult to process, it is preferable to avoid using the magnetic material in a region where a delicate shape is required. All or a part of the wall of the processing tank or the processing tank where the processing liquid or the processing gas stays can be made of a magnetic material, or the processing tank or the processing tank or the entrance or exit thereof has a lattice shape, a wire mesh shape, or the like. A magnetic material can be used as an insert in the form of an arbitrary shape such as a perforated plate, a lashing, or a sphere. These inserts can optionally have an inorganic antimicrobial agent, for example, a plated layer of a germicidal metal. In addition, when processing gas, inserts such as a blower fan and a ventilation fan can be mentioned.
For example, silver plating may be applied, and a material that is combined with a lattice or wire mesh made of a magnetic material such as ferromagnetic ferrite may be used as the insert. Further, a combination of a blower fan and a ventilation fan made of a magnetic material and a grid or a wire mesh plated with sterilizing metal may be used.

Since the magnetic material captures a magnetic metal or the like existing in the processing solution or the processing gas, it is necessary to remove the captured material at an arbitrary stage.

As the bactericidal material of the present invention, either an inorganic antibacterial agent or an organic antibacterial agent can be used (for example, P
etorotech. Vol. 21, No. 4, pp. 63-68).

As the inorganic antibacterial agent, there are an inorganic bactericide and an antibacterial agent for inorganic antibacterial products, and both can be used.

The inorganic fungicides include mercury compounds such as mercuric chloride and mercury oxycyanide; silver compounds such as silver nitrate; chlorine compounds such as sodium hypochlorite and chlorine dioxide; iodine such as iodine and iodoform. Compounds; boron compounds such as boric acid; peroxides such as hydrogen peroxide and potassium permanganate; limes such as quicklime, and metal oxides such as titanium oxide, zinc oxide and silver oxide.

The antibacterial agent for the inorganic antibacterial product includes a metal-carrying type, a bactericidal metal compound such as a metal oxide or an organic antibacterial agent-carrying type. Metal supported type is zeolite, silica gel, silicate glass, viroxyapatite,
Ag, H on inorganic carriers such as calcium phosphate, poorly soluble phosphate, zirconium phosphate, silicate and titanium oxide.
g, Cu, Cd, Au, Co, Ni, Pb, Fe, A
Examples thereof include those carrying a bactericidal metal such as 1, Zn, Mn, Ba, Mg, and Ca. Examples of bactericidal metal compounds such as metal oxides include titanium oxide and zinc oxide. In addition, the organic antibacterial agent-carrying type may be one in which an antibacterial organic substance such as a quaternary ammonium salt or a secondary amine is supported on the carrier.

The organic antibacterial agent is methyl-2-
Examples include benzimidazole carbamate, trichlorocarbanilide, hexamine, chlorhexidine gluconate, benzalkonium chloride, fatty acid monoglyceride, alkylpyridinium halide, and alkyltrimethylammonium halide such as cetyltrimethylammonium halide.

In the case of the metal-carrying type, the minimum inhibitory concentration of bacteria varies depending on the type of metal in the system.
Are shown): Ag: 2 × 10 ⁻⁶ , Hg: 2 × 1
0 ⁻⁶ , Cu: 1.5 × 10 ⁻⁵ , Cd: 6.0 × 10
⁻⁵ , Au: 1.2 × 10 ⁻⁴ , Co: 1.2 × 10
^-4 , Ni: 1.2 × 10 ^-4 , Pb: 5.0 × 10
^-4 .

The surface layer made of a metal compound such as a bactericidal metal or a bactericidal metal oxide may be formed by plating on a predetermined metal material using the bactericidal metal or its alloy, Alternatively, it can be achieved by composite plating of particles containing these metal components or particles of a bactericidal metal compound (such as a metal oxide). Although there is no particular limitation on the size of the particles, it is preferable because the surface area is preferably larger as fine particles, and preferably 5 μm
The following is preferred. There is no restriction on the thickness of the surface layer,
Usually, about 5 to 20 μm is sufficient. Further, a material in which germicidal metal particles are dispersed in an arbitrary metal material can be used. In some cases, when a filter made of a nonwoven fabric or a woven fabric is used, these fibers can be vacuum-deposited with a metal or metal oxide, or can be impregnated with an organic antibacterial agent. In particular, when treating gas, the combined use of a filter (filter cloth) is effective. In particular, HEPA (High E

It is effective to use a Penetration Air) filter and a combination thereof.

The germicidal material may be coated on any part of the component member by a coating means such as plating, so that more parts can be used than magnetic parts can be used. Particularly suitable portions for plating include an inner surface of a transfer pipe, an inner wall of a processing tank or a processing tank, a stirring propeller, a transport fan, a filter, and the like. In addition, the surface of any shape such as lattice, wire mesh, cloth, perforated plate, lashing, sphere, particle, etc. can be sterilized inside the processing tank or processing tank or at the entrance / exit area (such as a pipe). What has been provided with a coating layer of a conductive material can be moored or charged. In particular, 1 μm to several meters
When the surface of the fine particles of m is coated with a bactericidal material (for example, silver plating) and is put into a treatment tank, the surface area can be increased, so that the effect is large. As long as the magnetic material particles are coated with a bactericidal material, the requirement of the combined use of the magnetic material and the bactericidal material can be satisfied with this alone. In addition, plastic particles having a surface coated with a germicidal material such as Ag can also be used. Since the particles can be light, if the treatment system is a liquid such as water, the particles float after the treatment, so that separation is easy. In a processing tank or tank with an insert having a sterilizing material on the surface, or in a processing tank or tank with a sterilizing material on the surface layer, use a normal stirrer or a later-described application developed by the applicant. If a representative vibration stirrer is provided, there is a certain effect even without magnetic material,
Compared with the case where the magnetic material is used together as in the present invention, the effect is far less.

Most of the organic antibacterial agents are water-soluble. In both cases of organic and inorganic systems, in the case of a water-soluble antibacterial agent, the antibacterial agent is encapsulated in a water-insoluble, antibacterial agent-permeable capsule, and this is dispersed in a binder such as a synthetic resin. It can be applied to the insert or device surface, or can be present in the plating layer using composite plating techniques. As the encapsulating agent, a synthetic or natural resin can be used, and any known encapsulation method can be used.

The bacteria to be sterilized or sterilized in the present invention are not particularly limited, but may be at least coliforms (Escherichia coli, pathogenic Escherichia coli, O-15).

Well water, waste water, plating cleaning liquid, vegetable cleaning liquid, dishwashing liquid, and the like can be mentioned. Examples of the processing gas include indoor air, especially air from hospitals and nursing homes, and air from food factories and the like.

The sterilizer of the present invention does not prevent the use of the sterilizer in combination with other sterilizers, and may use a germicidal lamp (ultraviolet irradiation), an ozone generator, or the like as necessary.

However, when the propeller or the disk is made of a non-magnetic material, any part of the processing tank, the processing tank, or other devices is made of a magnetic material.

6. Covering or impregnating wire mesh, filter cloth, etc. with a bactericidal material (In the case of filter cloth, etc., bactericidal metal or metal oxide is coated on each thread by means of vacuum deposition or sputtering at the fiber stage. A filter made of a bactericidal material obtained by subjecting a synthetic fiber cloth to metal, which is a bactericidal material, by employing a metal plating means for plastic, and a magnetic material can be used. For example, an arbitrary number of stages are stuck to a lattice-shaped object alternately or at a predetermined interval (eg, an interval of 5 to 20 mm).
Open the sheets and put them on top of each other. If necessary, use them in a cartridge.

7. The magnetic material, the germicidal material-coated material, or the cartridge body or the like combining these materials is used for 10-2.
By giving a vibration of 00 Hz, preferably 20 to 60 Hz by a motor with an amplitude of 0.2 to 10 mm,
The sterilization effect can be further improved.

When treating the liquid with the sterilizer of the present invention, it is preferable to agitate the liquid in the treatment tank. The stirring means is
Any stirring means such as ordinary propeller stirring can be employed, but the most preferable ones are Patent Nos. 19414498 and 276238 according to the development of the present inventors.
No. 8, No. 2988624, No. 2988440, No. 3
No. 4,064,594 and the like.

The vibration stirrer used in the present invention comprises a vibration generating means including a vibration motor capable of generating an arbitrary vibration between 10 and 500 Hz by an inverter, and a vibrating rod vibrating in the processing tank in association with the vibration motor. And a vibrating flow stirrer comprising vibrating blades fixed in one or more stages so as to be non-rotatable.

It is preferable to provide any vibration absorbing means at the connection between the vibrating stirrer and the processing tank in order to prevent the vibration transmitted to the vibrating rod from unnecessarily vibrating the processing tank and the like.

As one vibration absorbing means, as shown in FIG. 25, a metal rod 47 extending downward from the vibration stirrer side and a metal rod 48 extending upward from the processing tank side do not come into direct contact with each other so as to prevent direct contact. Vibration absorbing means in a state where the rod is wrapped around by a spring 5 can be used.

As another vibration absorbing means, (1) a rubber plate or (2) a laminate of a rubber plate (plate-like rubber) and a metal plate is provided at a connection portion between the vibration generating means and the processing tank. Vibration absorbing means (see Japanese Patent Application No. 11-127830, pages 2 to 5 of the present application).

Further, it is preferable to provide a vibration stress dispersing means at a connecting portion between the vibration generating means and the vibrating rod (see Japanese Patent Application Laid-Open No. Hei 8-173785 filed by the present applicant).

Examples of the vibration stress dispersing means in the present invention include the following means.

One vibration stress dispersing means is a rubber ring 18 provided around the vibration bar below the vibration generator at the connection between the vibration generating means and the vibration bar (see FIG. 3). In particular, its length is longer than the diameter of the vibrating rod,
It is preferable that the diameter of the vibrating rod is 3 to 8 times and the thickness thereof is 1.3 to 3.0 times, particularly about 1.5 to 2.5 times larger than the diameter of the vibrating rod. From another viewpoint, when the diameter of the vibrating rod 8 is a round bar having a diameter of 10 to 16 mm, the thickness of the rubber ring 18 is preferably 10 to 15 mm, and the diameter of the vibrating rod (round bar) 8 is 20 to 15 mm. When it is 25 mm, the thickness of the rubber ring 18 is preferably 20 to 30 mm. For example,
As shown in FIGS. 3 and 4, when connecting the vibration rod 8 to the vibration transmission member 3, the vibration rod 8 is inserted into a predetermined hole of the vibration transmission member 3.
, The ends of the vibrating rod 8 are fixed by nuts 12 and 13 and a washer ring 16, while the opposite side of the vibration transmitting member 3 is inserted with the rubber ring 18 into the vibrating rod 8,
It is fixed with nuts 14 and 15. In the case where the rubber ring 18 is not used, there is a problem that the vibration stress concentrates near the joint between the vibration transmitting member and the vibration bar, and the vibration bar is easily broken. By doing so, it was completely eliminated. In particular,
When the vibration frequency was increased to 100 Hz or higher without using the rubber ring, the vibrating rod was often broken. However, the frequency can be increased without such a concern.

The rubbery ring is made of hard natural rubber, hard synthetic rubber, synthetic resin, or the like, having a Shore A hardness of 80 to 120;
Preferably, it can be composed of 90 to 100 hard elastic bodies. In particular, hard urethane rubber having a Shore A hardness of 90 to 100 is preferable in terms of durability and chemical resistance.

Another means for dispersing vibration stress is to insert a metal wire bundle between the vibration generator and the vibration bar at the connection between the vibration generator and the vibration bar. For example, as shown in FIG. 5, the vibration transmitting member 3 (or the vibration basic member)
In connecting the vibrating rod 8 with the auxiliary vibrating rod 8 ′ and the metal wire bundle 23. In some cases, the metal wire bundle 23 can be directly connected to the vibration transmitting member 3 without using the auxiliary vibration bar 8 ′. Specifically, one end of the auxiliary vibrating rod 8 'is connected to the nuts 12, 12', 13, 1
3 ', and is fixed to the vibration transmitting member 3 by the washer rings 16 and 16'.
, And one end of the metal wire bundle 23 was connected to the other end of the metal wire bundle 23 using the connection ring 21 and the nut 22. Thereby, the same effect as when the rubber ring is used can be obtained.

The metal wire bundle is of a type whose structure is frequently used as a cable for a suspension bridge, and is a bundle of many single metal wires or metal stranded wires bound at the ends from the outside. A metal coating is used. The connection between the metal wire bundle and another object can be achieved by cutting a screw in the metal coating portion.

The size of the metal wire bundle is such that the diameter is the same as that of the vibrating rod, and the length is such that the coating portions of the upper and lower metal wire bundles and the connection rings attached to the coating portions do not come into contact with each other due to vibration. If there is.

The vibration is performed by a vibration motor or the like that generates a vibration of 10 to 500 Hertz (Hz), preferably 20 to 400 Hertz (Hz). The relationship between the output of the vibration motor and the stirring capacity is as follows in the case of a normal aqueous solution.

[Table 1] Output of vibration motor Stirring capacity 75W (200V, 3 phase) -200 liters 150W (200V, 3 phase) 200-350 liter 250W (200V, 3 phase) 350-800 liter 400W (200V, 3 phase) 800リ ッ ト ル 1500 liters 750 W (200 V, 3 phase) 1500 な お 2500 liters If the motor output is set to 3 KW, a 100 m ³ capacity can be sufficiently stirred.

Normally, as shown in FIGS. 20 to 24, the vibration motor 1 is set on the gantry 2 placed on the processing tank 7, on the side wall of the processing tank, or on a hard floor. When the tank is thin (stainless steel tank 5 mm or less) and vibration is transmitted to the tank side wall or floor by the vibration of the liquid, it is preferable to install a gantry outside the tank. When the thickness of the tank is 5 mm or less, a reinforcing member may be attached to the side wall of the tank in such a manner as to fasten a band, and a vibration device may be installed there. The vibration generated by the vibration motor is transmitted to the vibration rod 8 via the basic vibration member 2. In this case, it is preferable that the vibration motor is normally set so as to be suspended below the basic vibration member. By doing so, the center of gravity can be lowered, and the occurrence of lateral displacement can be reduced.

The vibration generator of the present invention usually employs a system in which the basic vibration member 2 and the vibration transmission member 3 are vibrated by a vibration motor (including an electric motor and an air motor). When stirring a system containing a flammable organic solvent, an exposure-proof vibration motor is used. Further, a vibration generating means such as an electromagnetic magnet or an air gun can be used instead of the vibration motor.

For example, as shown in FIGS. 20 to 24, a gantry 6 is placed on a processing tank 7 via an elastic body 11, and a basic vibration member 2 is provided on a support frame with a spring 5 thereon. Attach the vibration motor 1. The vibration source may be mounted above the basic vibration member. However, when the vibration source is mounted below, the center of gravity of the vibration generating source is lowered, and unnecessary lateral movement can be prevented. In FIG. 20, the vibration motor 1 is located below the basic vibration member 2 and above the vibration transmission member 3. However, if the vibration motor 1 does not interfere with the vibration transmission member 3, the vibration motor 1 is suspended below the vibration transmission member 3. You can also lower it. Also, as shown in FIG.
The vibration motor is attached to the lower part of the basic vibration member 2 and the vibration rod 8
Can be attached to both sides of the vibration motor. In this case, the vibration transmission member 3 is unnecessary, and the size can be reduced. The vibration motor 1 does not necessarily need to be provided on the processing tank 7, but extends a basic vibration member or a vibration transmission member to the outside of the stirring tank, and attaches a vibration motor to the upper or lower side of the extended basic vibration member. Vibration can also be transmitted to a vibrating rod.

The non-rotating vibrating blade portion is composed of a vibrating blade plate and a fixing member for the vibrating blade plate, or a laminate of a plurality of vibrating blade plates, or an integrally molded vibrating blade plate and a fixing member for the vibrating blade plate. Can be used.

As the material of the vibrating blade, preferably, a thin metal, elastic synthetic resin, rubber, or the like can be used as a material, but at least a tip portion of the blade is fluttered by a vertical vibration of the vibrating motor. It is preferable to use a material which can give a flow to the system in addition to the vibration. Titanium, aluminum, copper, steel, stainless steel, and alloys thereof can be used as the material of the metal vibrating blade. As the synthetic resin, polycarbonate, vinyl chloride resin, polypropylene and the like can be used. The thickness is not particularly limited in order to increase the effect of vibration by transmitting vibration energy, but generally 0.2 to 2 mm for metal and 0.5 for plastic.
10 to 10 mm is preferred. If the thickness is excessively large, the effect of the vibration stirring decreases.

When an elastic synthetic resin, rubber, or the like is used as the material of the vibrating blade, the thickness is not particularly limited, but is generally preferably 1 to 5 mm. In the case of a metal such as stainless steel, it is preferably 0.2 to 1 mm. It is preferably 0.5 mm. The amplitude of the diaphragm is 0.2 to 30 m
m, preferably 1 to 10 mm.

The vibrating blade can be attached to the vibrating shaft in one or more stages. When the number of vibrating blades is multi-stage, 5 to 7 blades are preferable depending on the size of the vibrating motor. When the number of stages is increased, if the load of the vibration motor is increased, the vibration width decreases, and the vibration motor may generate heat. The vibrating blade plate may be integral. The angle of the vibrating blade portion may be horizontal with respect to the vibrating axis, but it is preferable that the inclination angle α (see A in FIG. 11) is inclined at 5 to 30 degrees, particularly 10 to 20 degrees to give directionality to vibration (FIG. 24).

The vibrating blade can be formed by sandwiching the vibrating blade from both upper and lower surfaces with a vibrating blade fixing member and fixing it to the vibrating rod. Further, as shown in FIG. 11, it is preferable that the fixed member 10 for vibrating blades and the vibrating blade 9 are integrally inclined and / or curved as viewed from the side surface of the vibration shaft. Even if it is curved, it is preferable to have an inclination of 5 to 30 degrees, especially 10 to 20 degrees, as described above. It is effective to disperse the vibration stress if the vibrating blade plate and the fixing member for the vibrating blade plate have the same inclination and / or curved surface. In particular, when the vibration frequency becomes high, Damage can be avoided.

Further, the vibrating blade plate and the fixing member for the vibrating blade plate can be manufactured by integrally molding, for example, using plastics (see FIG. 11C). In this case, compared with the case where the vibrating blade plate and the fixing member for the vibrating blade plate are used separately, it is possible to avoid a disadvantage that the object to be processed permeates and adheres to the joint portion, and it takes time to clean. . Further, by integrating the blade plate and the fixing member as shown in FIG. 11, a thickness step does not occur and stress concentration can be avoided, so that damage to the blade plate can be avoided.

On the other hand, if the vibrating blade plate and the fixing member for the vibrating blade plate are separately manufactured, only the vibrating blade plate can be replaced. However, an integrally formed vibrating blade plate can be replaced. In this case, the vibrating blade plate, the fixing member for the vibrating blade plate, and the integrally molded product are not limited to plastics, and various materials described above can be used. When using the fixed member 10 for the vibrating blade, the vibrating blade plate is sandwiched and used from above and below. However, as shown in FIG. 12A, the fixing member is vertically different in size. It is also possible to disperse the vibration stress.

As another modification, FIG.
As shown in FIG. 2 (b), a play 32 can be provided on one or both of the upper and lower portions of the distal end portion of the fixing member 10, whereby the stress can be dispersed as in (a). If necessary, the play 32 can be supplemented with a rubber member to absorb vibrations or extend the life of the blades and the fixing member. Further, as shown in FIG. 13, vibrating blade plates having different dimensions can be laminated (not bonded to each other) using thin blades to form a fixing member and a vibrating blade plate. In this case, as shown in FIG. 13A, the size of the diaphragm is made smaller as it goes down, so that the entire thin blade can be vibrated integrally and the fixing member can be replaced with a nut. These means all contribute to dispersing the stress applied to the vibrating blade. FIG. 13B shows a modification thereof. This is also effective in dispersing the vibration stress. Further, the shape of the vibrating blade plate can be configured in various shapes such as those shown in FIGS.

The vibrating blade portion made of the vibrating blade plate or the fixing member for the vibrating blade plate can be fixed to the vibrating rod using a nut. When a large number of vibrating blades and / or fixing members for vibrating blades are mounted on the vibrating rod, FIG.
After fixing with a nut 29 as shown in (1), one or a plurality of cylindrical spacers 30 having a fixed length just fitted to the vibrating rod are inserted, thereby fixing the vibrating blade plate and / or the vibrating blade plate. The interval between members can be easily fixed.

The shape of the vibrating blade plate (or vibrating blade portion) can adopt various shapes. One example is shown in FIGS. In these cases, it is preferable to provide the notch 27, but if the notch 27 extends to the fixing member 9, the fixing member 9 tends to be damaged. Preferably, the shape of the notch is also V-shaped. The vibrating blades need not be symmetrical about the vibrating rod, and may be provided on only one side.

When the vibrating blades are inclined and / or bent, the lower ones among a number of vibrating blades.
Two sheets may have a downward inclination and / or curvature, and the other may have an upward inclination and / or curvature (see FIGS. 20 and 24). This way,
The bottom of the processing tank can be sufficiently agitated, and the formation of pool at the bottom can be prevented.

When it is not desired to agitate only the bottom of the processing tank, it is possible to cope with it by removing the downwardly curved vibrating blade. In the case where the reaction proceeds by stirring, it is convenient to collect the portion where the reaction is completed in the lower portion and take it out from the lower portion without diffusing it.

Although the above description has been made of the case where the number of vibrating bars is one, it is needless to say that a plurality of vibrating bars may be used. is there.

When it is desired to positively generate convection in the system by vibrating agitation and to prevent accumulation at the lower part of the processing tank, all vibrating rods have upward inclination or curl as shown in FIG. A vibrating blade having a curve (of course, the case where a fixing member is used is included, but in FIGS. 12 to 15, the fixing member and the nut are all omitted in the drawings).
Can be achieved by providing all the other vibrating bars with vibrating blades having a downwardly inclined curvature.

In addition to the type in which a number of vibrating blades are independently provided for each vibrating bar, the type in which a number of vibrating blades are connected across two or more vibrating bars (hereinafter referred to as a connection type vibrating blade portion) May be). For example, FIG.
5 is a large number of vibrating blades 9, 9 between the two vibrating rods 8, 8.
.. Are provided.

In this case, the vibrating blade may be horizontal or inclined, and the vibrating blade may be flat or curved. Is as described above (see FIGS. 17A and 17B).

Also, the lower and upper vibrating blades can be tilted and / or bent in the downward direction and the other vibrating blade plates, respectively, unlike the case of the single vibrating blade plate. It is not different (see FIG. 17B).

Further, two pairs of connection type vibrating blades as shown in FIG. 15 can be provided on both left and right sides of the processing tank, or the left vibrating blade can be tilted or bent upward on the right vibrating blade. By pointing all downwards, convection of the processing tank can be promoted.

FIG. 16 shows a case in which a single-type vibrating blade (single-type vibrating blade) and a connected-type vibrating blade are provided in combination.

The degree of the “bending phenomenon” of the vibrating blade plate caused by the vibration of the vibrating blade portion depends on the frequency at which the vibration is applied,
The length and thickness vary depending on the length and thickness of the vibrating blade plate, the viscosity of the material to be stirred, the specific gravity (density), and the like. With the frequency and the thickness of the vibrating blades constant,
As the length of the vibrating blade is changed, the degree of bending of the vibrating blade increases up to a certain stage as the length (length of the portion before the fixing member) increases as shown in FIG. However, it has been found that the bending becomes too small, the bending becomes small at a certain length, and the bending becomes large as the vibrating blade plate becomes longer. FIG. 19 shows a model of this state.

Therefore, it is preferable that the length of the vibrating blade (the length of the portion ahead of the fixing member) is selected to be the length indicating the first peak or the length indicating the second peak. Is preferred. Whether the length has the length indicating the first peak or the length indicating the second peak can be appropriately selected depending on whether the vibration of the system is increased or the flow is increased. When the length showing the third peak is selected, the vibration width becomes small, and the use is limited.

SUS at frequency 37-60Hz, 75KW
When the length of the first peak and the length of the second peak were obtained for various thicknesses of the diaphragm made of 304, the following results were obtained.

[Table 2] Note that the length in this experiment is the length from the tip of the fixing member for the vibrating blade to the tip of the vibrating blade (the length of m in FIG. 11A). Length to the tip of the fixing member (n in FIG. 11A)
Is 27 mm, and the inclination angle α of the vibrating blade is upward 1
This is the case of 5 ゜.

The preferable range of the thickness of the vibrating blade plate varies depending on the viscosity of the object to be processed and the vibration conditions. However, the thickness of the vibrating blade plate should be such that the vibrating blade plate does not break and can be sufficiently operated like a blade. The efficiency of vibration stirring can be improved most.

From this point, it is presumed that the vibrating blade plate greatly contributes to the flow of the system, and the vibrating blade plate fixing member contributes to the vibration of the system.

In order to fix to the vibrating rod, a vibrating blade portion such as a basic vibrating member or a vibration transmitting member can be fixed by using a nut (the nut is often omitted in the figure). Alternatively, a stopper ring can be used. FIG. 18 shows an example of the stopper ring 41. It is preferable to use an elastic body for a portion that comes into contact with the vibrating blade portion, such as the vibrating blade plate or the fixing member for the vibrating blade plate, because the fixation is stabilized. In the figure, 42 is a stopper ring main body, 43
Is a screw. By using the stopper ring, the length of the vibration bar in the liquid can be changed by moving the vibration bar up and down, so that the length of the vibration bar can be arbitrarily adjusted according to the size of the processing tank. Further, the vibrating rod can be easily replaced with a plastic or the like rather than a metal. Thus, the fact that the stirring means such as the vibrating rod and the vibrating blade can be easily changed depending on the properties of the liquid in the processing tank cannot be performed by a conventional rotary stirrer at all.

In the present invention, the vibration generating means and the processing tank are provided with three or more, preferably four, support rods extending vertically downward from the vibration generating means as shown in FIGS. 20a and 21a. Correspondingly, it is preferable to engage with a support rod extending vertically upward from the processing tank side and a spring surrounding the upper and lower support rods. In particular, the upper and lower support rods are preferably kept in a non-contact state by the spring. As a result, even if the vibration generating device causes a lateral shake, the above-mentioned engaging portion can absorb the lateral shake well, and it is possible to prevent the occurrence of an undesirable lateral shake and the generation of noise accompanying the entire device. it can.

FIGS. 20, 21, 23 and 24 show the vibration stirrer provided with the anti-sway mechanism. FIG. 25 is an enlarged view of the anti-sway mechanism in these figures.
In the drawing, 5 is a spring, 46 is a processing tank or a gantry or reinforcing member provided thereon, 47 is a support rod extending vertically below the basic vibration member or vibration transmitting member, and 48 is vertically extended above the above 46. It is a support rod.
