In Japanese Patent Application Laid-Open Publication No. 2000-125, the vibrating blade is moved from 200 to 10 per minute.
We have proposed various technologies related to vibration stirrers based on vibrating a large number of vibrations, such as 000 times, with an amplitude of 20 mm or less and 0.1 mm or more, and succeeded in bringing the world's first production device to the market. .

[0003] These vibrating stirrers proposed so far mainly consist of (1) as shown in FIGS.
A type in which one or a plurality of vibrating blades 9 are mounted on one vibrating rod 8, and one vibrating motor 1 is mounted on one vibrating rod 8, (2) one vibrating rod 8, 8 Alternatively, a plurality of vibrating blades 9 are mounted, and one or a plurality of vibrating blades 9 are mounted between the two vibrating bars 8, 8, and the two vibrating bars 8, 8 are connected to the basic vibrating member 2 and tied. It was of a type in which one set of vibration units was attached to one vibration motor 1.

However, when the tank requiring vibration stirring is a large tank or when a number of tanks are provided side by side, the vibrating rod 8 of (1) or the vibrating unit of (2) Were connected by one connecting vibration member, and two vibrating motors having the same wattage were attached to both ends, a total of two vibrating motors, to reduce the number of vibrating motors used.

[0005] However, unexpected vibrations caused by the vibration motors at both ends may cause unexpected vibrations of a plurality of vibrating rods or vibrating units.
It was found that some that did not vibrate occurred and that practical application was impossible.

For example, when 750 W motors are used as the vibration motors at both ends, one of the vibration motors is turned to the left and the other is turned to the right, or both vibration motors are turned to the same left. In addition, the vibration of each vibrating rod or vibrating unit is not uniform, and the stirring cannot be uniform. Also, when the frequency of both vibration motors was set to different frequencies by the inverter, the connected vibration members connecting the multiple vibration bars and vibration units vibrated extremely violently, preventing normal stirring and generating loud noise. . Further, when the frequency is set to the same frequency, the whole resonates and the vibration becomes non-uniform, and there are places where the vibration is weak or where the vibration hardly occurs.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vibrating stirrer of a type in which a plurality of vibrating rods or vibrating units are connected by one connecting vibrating member and a vibrating motor is attached to both ends. An object of the present invention is to provide a vibration stirrer that does not generate resonance due to a vibration motor.

[0008]

According to the present invention, a plurality of vibrating rods or vibrating units having vibrating blades are fixed to a connecting vibrating member, and outputs, for example, different wattage (W number) are provided at both ends of the connecting vibrating member. The present invention relates to a multi-shaft vibration stirrer, which is provided with a transmission mechanism for transmitting vibration of a vibration motor.

Preferably, the vibration motor is connected to an inverter capable of generating any vibration between 10 and 500 Hz.

[0010] Commercially available vibration motors include a 40 W, 75 W
W, 0.15 kW, 0.25 kW, 0.4 kW, 0.7
5 kW, 1.2 kW, 1.7 kW, 2.2 kW, 3.0
kW, 5.0 kW, 20 kW, 37.5 kW, 50 k
Although there are various W numbers such as W and 125 kW, the present invention can be used in combination with motors having substantially adjacent W numbers. Normally, the output W number of the vibration motor having the larger W number is preferably 1.25 to 2.25 times the output W number of the vibration motor having the smaller W number.

In the present invention, when a vibrating rod or a vibrating unit is connected to a continuous vibrating member connected to a vibrating shaft of a vibrating motor by some means, it is preferable to provide a vibrating stress dispersing means at a connection portion between the two.

As such a stress dispersing means, there can be mentioned a stress dispersing means described in JP-A-8-173785 according to the invention of the present inventor. That is, one vibration stress dispersing means is that the rubber ring provided around the lower and / or upper vibrating rod of the vibration generating device at the connection between the vibration generating device and the vibrating rod has a length corresponding to that of the vibrating rod. It is longer than the diameter, usually 3 to 8 times the diameter of the vibrating bar, and its thickness is 1.3 to 3.0 times larger than the diameter of the vibrating bar.
A factor of two times, especially about 1.5 to 2.5 times, is preferred.
From another viewpoint, when the vibrating rod is a round bar having a diameter of 10 to 16 mm, the thickness of the rubber ring is 10 to 15 m.
m is preferable, and the diameter of the vibrating bar (round bar) is 20 to 25 mm.
In this case, the thickness of the rubber ring is preferably 20 to 30 mm. For example, as shown in FIGS.
When connecting the vibrating rod 8 to the nut, the vibrating rod 8 is passed through a predetermined hole of the vibration transmitting member 3 and the end of the vibrating rod 8 is
3. The rubber ring 1 is fixed to the vibrating rod 8 on the other side of the vibration transmitting member 3 by the washer ring 16.
8 is fixed by 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, vibration can be reduced to 100 without using a rubber ring.
When the frequency is increased to more than Hz, the vibrating rod often breaks, but this can increase the frequency 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 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 carried out by a vibration motor or the like which generates a vibration of 10 to 500 Hertz (Hz), preferably 20 to 400 Hertz (Hz), particularly preferably 50 to 300 Hertz (Hz). The relationship between the output of the vibrating motor and the stirring capacity varies depending on the number of connected vibrating rods or vibrating units. When the number of connected vibrating rods is 4 to 5, the following combinations are usually possible. In addition, when stirring the thing with high viscosity, even higher output may be required. Combination of vibration motor Total stirring volume 40W × 75W-100L 75W × 150W-150L 150W × 250W-300L 250W × 400W-400L 400W × 750W-500L

The non-rotating vibrating blade portion may be composed of a vibrating blade plate and a fixing member for the vibrating blade plate, or a stack of a plurality of vibrating blade plates (see FIG. 13), or a vibrating blade plate and a fixing member for the vibrating blade plate. (See FIG. 11) can be used.

As the material of the vibrating blade, preferably, a thin metal, a resilient synthetic resin, rubber or the like can be used as a material, but at least the tip portion of the blade is fluttered by a vertical vibration of the vibrating motor. Hitting 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. For example, the one having 0.5 mm is preferable. The amplitude of the diaphragm is 2 to 30 m
m, preferably 5 to 10 mm.

The vibrating blades 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 the vibration.

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, the integrally formed one 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, it is used by sandwiching the vibrating blade from above and below.
As shown in FIG. 12A, the size of the fixing member may be different between the upper and lower portions, so that the vibration stress can be dispersed.

As another modification, FIG.
As shown in FIG. 2b, a play 32 can be provided on one or both or both of the top and bottom of the end portion of the vibrating blade fixing member 10, whereby the stress can be dispersed similarly to FIG. 12a. 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, by reducing the size of the diaphragm toward the bottom, the entire thin blade can be vibrated integrally and the fixing member can be replaced by a nut. These means all contribute to dispersing the stress applied to the vibrating blade. FIG. 13B is a modification thereof. This is also effective in dispersing the vibration stress.

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 FIG. 20 or FIG.
By inserting one or more of them, the interval between the vibrating blades and / or the fixing members for the vibrating blades can be easily fixed.

The shape of the vibrating blade plate (or the vibrating blade portion) can adopt various shapes. One example is shown in FIGS. In these cases, it is preferable to provide the notch 27. However, if the notch 27 extends to the fixing member 10, the fixing member 10 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 of a large 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 FIG. 16). 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.

If it is not desired to stir only the bottom of the stirring 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.

When it is desired to positively generate convection in the system by vibrating agitation to prevent the formation of a pool at the lower portion of the agitation tank, all vibrating rods have an upward inclination or a curve as shown in FIG. Vibrating blade having a curve (of course, the case where a fixing member is used is included, but in FIGS. 14 to 17, 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.

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

In addition, the lower and upper vibrating blades can be inclined and / or bent in a downward direction and an upward direction, respectively, unlike the case of the single vibrating blade plate. It is not different (see FIG. 17B).

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. Therefore, it is preferable to select the length and thickness that best yield at a given frequency. 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 is determined by the length of the vibrating blade (length of the part before the fixed member. )
Repeating the relationship that, as it becomes larger, it grows up to a certain stage, but when it passes it, the bending becomes smaller, at certain lengths there is almost no bending, and when the vibrating blades become longer, the bending becomes larger again I knew it. FIG. 18 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 indicating the third peak is selected, the vibration width becomes small, and the use is limited.

Although 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, it is preferable that the thickness of the vibrating blade plate is 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 fixing member for the vibrating blade plate contributes to the vibration of the system.

In the present invention, FIGS.
As shown in FIG. 1, three or more, preferably four, support rods 4 extending vertically downward from a vibration generator including a vibration motor.
7, it is preferable to be engaged by a supporting rod 48 extending vertically upward from the gantry 6 side and a spring 5 surrounding the upper and lower supporting 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.

FIG. 21 is an enlarged view of the lateral sway prevention mechanism. In the figure, 5 is a spring, 47 is a support bar extending vertically below the basic vibration member, and 48 is a support bar extending vertically above the gantry 6.

These motors are supported on a gantry by a support mechanism as shown in FIG. In this support mechanism, a support rod 48 fixed on the gantry 6 and a support rod 47 fixed under the basic vibration member 2 are provided to face each other. A spring 5 is attached.
