DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirrer for mixing, dispersing, reacting, emulsifying and defoaming a high-viscosity fluid which is a liquid or a mixture of the liquid and a powder, and degreasing and washing of articles. And a stirrer for measuring the permeation of articles. That is, the present invention is for mixing, dispersing, washing, defoaming, or the like, a liquid in a container such as a tank or a mixing tank included in a production line, or a high-viscosity fluid such as a mixture of this and powder in a container. Related to a stirring device.

[0002]

2. Description of the Related Art Conventionally, rotary mixing is mainly used for the manufacture of many chemical products such as cosmetics, foods, drugs, dyes, paints, inks, adhesives, surface treatments such as degreasing and plating, and fermentation reactions. Although a stirrer with blades has been used for a long time, there are various disadvantages. After stirring, dispersion is performed by additionally using a dispersing device such as a roll mill, a sand grinder, a colloid mill or the like.

[0003] The conventional rotary bladed stirrer has the following disadvantages. When it is desired to uniformly mix the liquid and the undissolved fine particle powder, when the stirring is stopped, there is a defect that the powder and the liquid are separated in a short time. If it is difficult to stir at the bottom of the container,
Precipitation may occur without complete dispersion. In order to cause the liquid to flow in a rotational manner, a large load resistance is initially applied, and extra power is required during the starting period. The liquid can be agitated with a uniform electric power by gradually adding the liquid, but a swirling flow is generated at the center, so that the air is easily swirled and the liquid to be stirred is likely to be chemically affected. In the case of mixing powders,
When the powder is gradually added, uniform mixing cannot be performed, and when the immersion portion is small, idling and the like may occur. Therefore, it is always necessary to check the liquid amount and the like. Furthermore, since the flow of the rotary blade is laminar with a stirrer or a pump, a considerable portion of the power used for stirring is used only for mutual friction, and the system cannot be sufficiently turbulent.

The inventor of the present invention has disclosed a technique for agitating a fluid by vibrating a vibrating blade by vibrating in the direction of a vibrating shaft on a vibrating rod protruding from a main body of a vibration generating device into a stirring tank.

However, high viscosities, especially viscosities of 10
It has been found that a fluid having a flow rate of 00 cps to 5000 cps is insufficiently agitated only by vibration.

Therefore, the present invention is intended to use rotation stirring in combination with vibration stirring, and a technique seemingly similar to this can be found in Japanese Utility Model Laid-Open Publication No. 52-158719. This is a plating solution stirring device consisting of a plate-like member that moves up and down in the plating bath and a rotary blade provided below the plate-like member. However, this plate-like member that moves up and down does not deserve to be called ultimate vibration. In addition, the plate-like member moving up and down and the rotary wing are constituted by separate members.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stirrer which is particularly suitable for high-viscosity fluids by taking advantage of the vibratory stirring while skillfully incorporating the advantages of rotary stirring. .

[0008]

The present invention comprises (1) a vibration generator including a vibration motor, and (2) a vibrating blade fixed thereto in one or more stages on a vibrating rod vibrating in a stirring tank in association therewith. Vibration stirring means, (3) Vibration motor is 20
(4) an inverter for adjusting an arbitrary vibration between 100 Hz and 100 Hz, and (4) a fluid stirring device comprising a vibration stress dispersing means provided at a connection portion between the vibration generating device and the vibrating rod. The vibrating blade has a tilt or a twist suitable for rotational stirring and is provided with a rotating means for imparting a rotational stirring force to the vibrating blade simultaneously with the vibration. The stirring for a high-viscosity fluid having a viscosity of 1000 to 5000 cps is provided. Related to the device.

The vibrating blade generates any specific vibration between 20 and 60 Hz by a vibration motor controlled by an inverter, and the material and thickness of the vibrating blade vibrate while the blade bends due to the vibration. Need to be something.

The shape of the vibrating blade is preferably such that the plate does not have a cut portion. If there is a cut, cracks are generated in the blade from the cut portion due to material fatigue due to vibration, which is not preferable. The most preferred shape is a strip having the same width as the base of the vibrating blade fixed to the vibrating bar except for the tip of the blade.

As the vibration stress dispersion means in the present invention, for example, the following means can be mentioned.

One vibration stress dispersing means is that a rubber ring provided around a lower and / or upper vibrating rod of the vibration generating device at a connecting portion between the vibration generating device and the vibrating rod has a length corresponding to the length of the vibrating rod. Is generally 3 to 8 times the diameter of the vibrating rod, and the thickness thereof is 1.3 to 3.0 times, especially about 1.5 to 2.5 times larger than the diameter of the vibrating rod. preferable. From another point of view, if the diameter of the vibrating rod is 1
When it is a round bar of 0 to 16 mm, the thickness of the rubber ring is preferably 10 to 15 mm. When the diameter of the vibrating bar (round bar) is 20 to 25 mm, the thickness of the rubber ring is 20 to 25 mm.
30 mm is preferred. For example, as shown in FIG. 3 or FIG. 4, when connecting the vibration rod 8 to the vibration transmission member 3, the vibration rod 8 is passed through a predetermined hole of the vibration transmission member 3, and the end of the vibration rod 8 is connected to the nut 12. , 13, and a washer ring 16 (in the case of FIG. 3, a rubber ring 18 'is interposed between the vibration transmitting member 3 and the washer ring 16).
On the other hand, on the opposite side of the vibration transmitting member 3, the rubber ring 18 is inserted into the vibrating rod 8 and fixed with nuts 14 and 15. In the case where the rubber rings 18 and 18 'are not used at all, 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 inserting the ring,
It was completely eliminated. In particular, when the frequency is increased to 100 Hz or higher without using a rubber ring, the vibrating rod often breaks, but this can increase the frequency without such 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, when connecting the vibration rod 8 to the vibration transmission member 3, an auxiliary vibration rod 8 'and a metal wire bundle 23 are interposed. 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, 13 ', the washer ring 16,
16 ′, the other end of the metal wire bundle 23 is connected to the other end of the metal wire bundle 23 via a nut 19 and a connection ring 20. The vibrating rod 8 was connected. This allows
The same effect as when the rubber ring is used can be obtained.

The metal wire bundle is of a type whose structure is often used as a cable for a suspension bridge, and is a bundle of many metal single 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 the same as the diameter of the vibrating rod, and the length is such that the covering portions of the upper and lower metal wire bundles and the connection rings attached to the covering 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 which generates a vibration of 20 to 100 Hertz (Hz), preferably 30 to 60 Hertz (Hz). The relationship between the output of the vibration motor and the stirring capacity is approximately as follows in the case of a normal aqueous solution.

[Table 1] When the motor output is set to 3 KW, a motor having a capacity of 100 m ³ can be sufficiently stirred.

Usually, a vibration motor is set on a stirrer, placed on a side wall of the stirrer 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. Tank thickness 5
If the diameter is less than 1 mm, 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 vibrating rod via the basic vibration member. In this case, it is preferable that the vibration motor is usually set so as to be suspended below the basic vibration member (see FIG. 1). 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 is generally a vibration motor (including an electric motor, an air motor, etc.).
A system for vibrating a basic vibration member, a vibration transmission member, and the like is adopted. When stirring a system containing a flammable organic solvent, a vibration-proof vibration motor is used. Also, a vibration generating means such as an electromagnetic magnet or an air gun can be used instead of the vibration motor.

The vibrating blade portion may be composed of a vibrating blade and a fixing member for the vibrating blade, a member obtained by stacking a plurality of vibrating blades, or a member integrally formed with the vibrating blade and the fixing member for the vibrating blade.

The vibrating blade can be preferably made of a thin metal, a resilient synthetic resin, rubber, or the like, but at least the tip portion of the blade plate has a flutter phenomenon (waves) due to vertical vibration of the vibrating motor. State)
It is preferable that the thickness 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. 0.5 mm is preferred. The amplitude of the diaphragm is 2 to 30 mm,
Preferably it is 5 to 10 mm.

The vibrating blades can be attached to the vibrating shaft in one or more stages. When the number of the 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 may have a certain angle, and the angle α (see FIG. 11) may be 5 to 30 degrees, particularly 10 to 20 degrees to give directionality to vibration. Can also.

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, the fixing member for the vibration blade and the vibration blade can be integrally inclined as viewed from the side surface of the vibration shaft.

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

On the other hand, if the vibrating blade and the fixing member for the vibrating blade are separately manufactured, only the vibrating blade can be replaced. However, the integrally formed one can be replaced. In this case, the vibrating blade, the fixing member for the vibrating blade, and the integrally molded product are not limited to plastics, and various materials described above can be used. When using the fixing member 10 for the vibrating blade, the vibrating blade is sandwiched from above and below and used. However, the size of the fixing member may be different between the upper and lower sides, thereby reducing the vibration stress. Can be dispersed.

As shown in FIG. 11, a synthetic resin sheet or a rubber sheet 31 is interposed between the vibrating blade fixing member 10 and the vibrating blade 9 so that the vibrating blade may be damaged by providing a cushioning effect. Can be prevented. Further, it is preferable that the synthetic resin sheet and the rubber sheet 31 are longer than the vibrating blade fixing member 10 and have a length slightly protruding in a tip direction of the vibrating blade.

The vibrating blade portion made of the vibrating blade or a fixing member for the vibrating blade 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, as shown in FIG. 1, after fixing with a nut 29, a cylindrical spacer 30 having a fixed length just fitted to the vibrating rod is used. By inserting one (see FIG. 1) or a plurality of (see FIG. 11), the intervals between the vibrating blades and / or the fixing members for the vibrating blades can be easily fixed.

The shape of the vibrating blade (or vibrating blade portion)
Various shapes can be employed. One example is shown in FIGS. The vibrating blades 9 and 9 in FIG. 7A may be made by cutting a single plate into a cross shape, or may be made by stacking two rectangular shapes. The fixing member 10 may be the same as the width of the vibrating blade [FIGS. 7 (a) and 8 (a)] or may be narrower than the width of the vibrating blade [see FIGS. 7 (b) and 8 (b)]. . In these cases, if a notch is provided in the blade as shown in FIGS. 7 and 8 of Japanese Patent Application No. 6-337183, the vibration blade and the fixing member tend to be damaged, so it is preferable not to provide the notch. .

When an angle α is given to the vibrating blade as shown in FIG. 11, as shown in FIG. 22 of Japanese Patent Application No. Hei 6-337183, one or two lower vibrating blades of a large number of vibrating blades face downward. The angle may be an angle, and the other angle may be an upward angle. In this case, the stirring at the bottom of the stirring tank can be sufficiently performed, and the formation of the pool at the lower portion can be prevented.

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

The degree of the “bending phenomenon” of the vibrating blade caused by the vibration of the vibrating blade is determined by the frequency at which the vibration is applied,
The length and thickness vary depending on the length and thickness of the vibrating blade, the viscosity of the material to be agitated, the specific gravity, and the like. When the frequency and the thickness of the vibrating blade are kept constant and the length of the vibrating blade is changed, the degree of bending of the vibrating blade becomes the length as shown in FIG. As the length increases, it increases up to a certain stage, but if it is too large, the bending becomes small, and some length hardly bends, and if the vibrating blade is made longer, the bending becomes larger again Has been found to be repeated. FIG. 9 shows a model of this state.

Therefore, it is preferable that the length of the vibrating blade (the length of the portion before 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] The length in this experiment is indicated by the length from the tip of the fixed member for the vibrating blade to the tip of the vibrating blade, and the length from the center of the vibrating rod to the tip of the fixed member is 2.
7 mm, and the angle α of the vibrating blade is 15 ° upward.

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

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

To fix to the vibrating rod, a vibrating blade 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). As shown in FIG. 18 of JP-A-6-337183, a stopper ring can be used instead of the nut. By using the stopper ring, the length of the vibrating bar in the liquid can be changed by moving the vibrating bar up and down, so that the length of the vibrating bar can be arbitrarily adjusted according to the size of the vibrating 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 vibrating tank cannot be performed by a conventional rotary stirrer at all.

In the present invention, three or more, preferably four, support rods 47 extending vertically downward from the vibration generator shown in FIGS. 1, 10 and 12 are provided. It is preferable that the support rod 48 and the upper and lower support rods 47, 48 extending vertically upward from the stirring tank side correspondingly engage with the spring 5. In particular, it is preferable that the upper and lower support rods 47 and 48 are kept in a non-contact state by the spring 5. This allows
Even if the vibration generating device is caused to sway, the above-mentioned engagement portion can absorb the sway properly, thereby preventing the undesired swaying of the entire device and the accompanying noise. Further, the manner of mounting the vibration motor may be the system shown in FIG. 1 or the system shown in FIG.

FIGS. 1, 2 and 12 show the vibration stirrer provided with the anti-lateral sway mechanism, and FIG. 10 is an enlarged view of the anti-lateral sway mechanism in these figures. In the drawing, 5 is a spring, 46 is a stirrer or a gantry or reinforcing member provided thereon, 47 is a support rod extending vertically below the basic vibration member or vibration transmission member, and 48 is vertically extended above the above 46. It is a support rod. The type shown in FIG. 1 is obtained by directly fixing a vibrating blade and stirring blade 9 to a vibrating rod 8 with a fixing member 10 for vibrating blades. The type shown in FIG. Are divided into rods 34, 34, and are rotated by the motor 2 around the vibrating rod 8. Vibrating blades 9, 9... Are spread over the divided vibrating rods 34, 34. ... is the vibrating rod 8
By vibrating while rotating about, both vibratory stirring and rotary stirring are given to the system. In the case of the type shown in FIG. 12, the inclination angle for giving the stirring force and the angle α are the same. FIG. 2 shows one embodiment in which the vibrating blade 9 is fixed to the vibrating bar 8 or the divided vibrating bar 34 by the vibrating blade fixing member 10.

In the present invention, since the vibrating blade itself is tilted or twisted so as to generate a stirring force by rotation, the direction affected by the vibration is extremely small as compared with the case where a blade having no twist is used. There is very little fluid in the bath tub that is complicated and thus unaffected by vibration. In addition, since the vibrating blade itself is rotating, the effect is further promoted.

The rotation speed is preferably in a range that does not impair the effect of vibration stirring, and is usually 20 to 500 rpm.
m, preferably 50 to 300 rpm.

As a rotating means for rotating the vibrating blade as a rotary stirring blade, the rotation of the rotary stirring motor 2 is normally transmitted to a pulley 28 via a V-belt 27 as shown in FIG. By rotating the vibrating blade 8, the vibrating blade 9 can also function as a stirring blade.

As shown in FIG. 2, the vibrating blade is inclined rather than horizontal as shown in FIG. 2 so that the vibrating blade also functions as a stirring blade as the blade rotates. give. In this case, the direction of inclination or torsion on the right side of the vibration axis may be the same as that on the left side of the vibration axis, or may be exactly the opposite.
It is preferable that the degree of the inclination and the degree of the twist be performed within a range in which the balance between the vibration stirring and the rotational stirring can be well balanced.

[0045]

[Effect] In the conventional agitation by only vibration, the viscosity of the fluid to be agitated is extremely effective for those having a viscosity of 1000 cps or less. However, the effect gradually disappears when the viscosity is further increased. In order to improve this, it is necessary to make the area of the blade occupy most of the area in the stirring tank. When the viscosity is low, only one vibrating device is needed.
You have to use it individually. On the other hand, according to the present invention, a high-viscosity fluid can be efficiently stirred even with a small stirrer for a container by using both vibration stirring and rotary stirring. Also, because the stirring is relatively slow,
A defoaming step after agitation is unnecessary without entraining air in the fluid.
