端には小径の支持軸２４ｃが設"Industrial Application Field" The present invention is a mixer device, in particular, in which stirring blades are basically stationary in a conduit, and when a fluid to be mixed flows, the fluid is repeatedly divided and merged by each stirring blade to achieve a desired stirring effect. This invention relates to the improvement of a static stirring type mixer device in which mixing is performed. [Prior art] Uniform stirring and mixing of multiple types of fluids, mainly liquids, gases, and powders, is extremely important in various industrial fields. In particular, in chemical processing or food processing, a mixer device that can achieve efficient and uniform mixing is desired.General mixing is performed by driving an agitating blade in a mixing tank by means of an electric motor, etc. However, in the past, static agitation mixers are well known in which mixing is performed naturally by simply following the flow of the fluids to be mixed without requiring any driving source, and a conduit that guides the fluids to be mixed is well known. A large number of stirring blades are arranged inside the fluid, and division and merging are repeated in sequence according to the flow of the fluid.Efficient mixing action can be obtained even with a short guide path, and the invention has been put to practical use in various fields. [Problems to be Solved] The above-mentioned static stirring type mixer device has the advantage of not requiring any driving source and can provide a mixing action that is sufficiently efficient for practical use. In order to mix more uniformly and with finer particle size than before in the field of paint mixing or fine chemicals,
In the conventional static + F mixed type MIKI device, there were cases in which a sufficiently satisfactory effect could not be obtained. On the other hand, depending on the stirring blade driven by the motor, there is a problem in that a large amount of kinetic energy is imparted to the mixed fluid itself, which can adversely affect its chemical properties.
Conventionally, there has been a desire for a new mixer device that can solve both of the problems of both types. The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to improve the mixing characteristics of a static mixing type mixer and to create an improved static mixer that can efficiently perform uniform stirring of fine particles. An object of the present invention is to provide a mixing type mixer device. [Means for Solving the Problems] In order to achieve the above object, the present invention provides a conduit for guiding fluids to be mixed, a stirring body disposed in the conduit and serving a plurality of stirring blades, and a conduit. or a vibration source that gives two or more different types of fibrillating movements to the stirring body according to an electrical input signal, and fibrillating the stirring body in a conduit in a compound mode to promote the stirring action of the fluid to be mixed. It is characterized by In the present invention, the compound fibrillation motion can be selected in various ways depending on the properties of the fluid to be mixed, and the fibrillation frequency and mode can be set appropriately. For example, the conduit and stirring blade itself are basically static stirring types, and stirring is performed by splitting and merging the fluid to be mixed when flowing, but in addition to these large stirring effects, the conduit or stirring blade itself vibrates. Since the source performs compound fibrillation motion, the stirring during the division and merging becomes extremely fine and uniform stirring, and when applied to food products, stirring with a smooth texture without roughness can be obtained, and it is also used in the fine chemical field. It is extremely suitable for stirring, especially polymers. For example, when whipping fresh cream in the food sector, fresh cream and nitrogen gas are introduced into a conduit as fluids to be mixed, and the fibrillating motion allows whipping of fresh cream to be performed extremely uniformly. It can also be applied to other manufacturing processes such as ice cream. Further, even when mixing other fruits with yogurt, it is possible to obtain a uniform and good mixing effect that does not destroy the fruits. Furthermore, as another example of food applications, the mixer device of the present invention is extremely useful in a process where wine is introduced into a conduit and the oxygen in the wine is pushed out by mixing with nitrogen gas to prevent oxidation of the wine. By mixing it with nitrogen gas, it is possible to remove oxygen from wine and prevent oxidation of wine without adding an antioxidant. Further, as another example of application of the present invention, it can be used for mixing during color matching of paints or for mixing ink. In the present invention, any method can be selected as the vibration source, but an electromagnetic drive type vibration source or an ultrasonic vibration source that can be easily electrically processed is mainly suitable. Further, in the present invention, the vibration source is a single vibration source fixed to a conduit, a stirring blade, or the entire device integrated with these, and a high-frequency vibration and a low-frequency vibration are combined in this single vibration source. It becomes possible to obtain the efficient mixing action in a composite mode of vibrations having different image frequencies. Further, in the present invention, separate driving sources are connected to the conduit and the stirring blade, and, for example, high frequency vibration is applied to the conduit and low frequency imaging is applied to the stirring blade, so that in this compound fibrillation motion mode, It is also possible to perform an efficient stirring action. Further, according to the present invention, the frequency is repeatedly or intermittently changed from low frequency to high frequency and supplied to a single driving source, and even by adjusting temporally different frequencies, good results can be obtained. It is also possible to provide multiple vibration modes. [Embodiments] Preferred embodiments of the present invention will be described below based on the drawings. FIG. 1 does not show an embodiment in which the Mikili device according to the present invention is driven by an electromagnetically driven vibration source. The conduit 10 has a cylindrical shape and is made of a material that is not affected by the fluids to be mixed, such as plastics such as vinyl chloride or suanless. Two introduction holes 10a and 10b are provided in the. Branch pipes 12.14 are airtightly fixed to both the introduction holes 10a and 10b, and different types of fluids to be mixed, indicated by symbols A and B, flow from each branch pipe 12.14 toward the conduit 10. be guided by Each branch pipe 12.14 is connected to a flow path (not shown) by a flange 16.18, and in the embodiment,

A flange 20 is fixed to the other end of the conduit 10, and although not shown, as is well known, it is airtightly connected to a downstream conduit, and the mixed fluid is guided to the next step. In said conduit 10 there is provided a stirring body 24 having a plurality of stirring blades 22, in this example J5, which itself essentially forms a conventional static stirring element. is characterized in that it is supported within the conduit 10 so as to be freely defibrillable. That is, like the aforementioned conduit 10, the stirring body 24 is made of plastic or stainless steel that is not affected by the mixed fluid, and one end of its shaft portion 24a is connected to the aforementioned conduit 10.
It has a slider portion 24b that fits with the inner diameter of the slider, and a small diameter support shaft 24c is provided at the other end.

G is supported by a bearing 26 fixed within the conduit 10. Therefore, it is understood that the stirrer 2/I is supported within the conduit 10 so as to be able to generate arbitrary fine vibrations in the axial or rotational directions. The stirring body 24 has a plurality of stirring blades = 7 as in the conventional case.
- The root 22 is fixed, and the stirring blade 22 in the embodiment has a half-moon shape. FIG. 2 shows the fixed state of the stirring body shaft 24a and each stirring blade 22 in the embodiment as seen from the axial direction, and in the embodiment, each stirring blade 22 is fixed at each fixed position. The blades are fixed symmetrically to both sides of the shaft portion 24a, and successively adjacent blades are aligned with a phase difference of 60 degrees. As is clear from FIG. 2, according to this embodiment, the stirring blades 22 are provided at a considerably large proportion to the opening area of the flow path, and as will be described later, each stirring blade 22 prevents fibrillation movement. When the fluid divided by the adjacent blades is vibrated by the fibrillation of the blades 22, the vibrations given by the adjacent blades interfere with each other, making it possible to obtain extremely fine stirring action. becomes. As described above, according to the present embodiment, the stirring body 2/1 is pivotally supported within the conduit 10 so as to be freely movable, but in this embodiment, in order to actually drive the stirring body 24, 1
A vibration source 28 is installed at one end of the stirrer 24, and 28 is an electromagnetically driven vibration source for vibration in the embodiment. The outer periphery of the diaphragm 30 made of a thin metal plate is firmly clamped and supported between a flange 32 and a fixing ring 34 that are airtightly fixed to the conduit 10.Of course, the diaphragm 30 is made of a thin metal plate. Gaskets 36 are provided at both ends to prevent fluid leakage.
4b, and for this purpose, a stator 38 is screwed and fixed to the end of the flange portion 24b, and the diaphragm 30 is firmly fixed to the flange portion 24.4b by the stator 38. It is fixed to the end of b. The diaphragm 30 allows the stirring body 24 to freely move in the axial direction due to its own flexibility, and the flange 32
By fixing the stirrer 24 to the fixed position, the stirring body 24 can be positioned and held at approximately a predetermined position. A movable coil 40 for forming a vibration source is mounted on the stator 38 with an insulating support frame/
12, and is movable from an external drive circuit to be described later.
0 is supplied with the desired drive current. This drive current is preferably supplied through a flexible printed circuit board or the like disposed on the surfaces of the stator 38 and the diaphragm 30, so that the movable coil/IO can be supplied as desired without impairing the flexibility of the diaphragm 30. Drive current can be supplied. On the other hand, a core 44 is located at a position facing the movable coil 40.
is fixed, and this core 44 is connected to the disk yoke 46.
, are integrally fixed to the fixed ring 3/I via a ring magnet 48 and a ring yoke 50. Each yoke 46,50 is made of a magnetic material, and the ring magnet 1-/18 is magnetized in its axial direction, so that a desired distance between the inner periphery of the ring 50 and the outer periphery of the right end of the core 44 is set. A magnetic gap is provided, and the moving coil 40
is disposed within this magnetic gap, and as described above, by supplying a complex alternating current to the moving coil 40, the moving coil 40 undergoes a complex vibration in the axial direction. The stirrer 24 that has been stirred makes a fibrillating motion in the axial direction and makes a loud noise. In this embodiment, the composite alternating current supplied to the moving coil 40 is supplied from two externally connected alternating current sources 60.
Consists of superimposed alternating currents from 2. Both alternating current sources 60,62 each consist of a low frequency source and a high frequency source, for example 5087 to 1 K at the normal commercial frequency.
The selected frequencies are sufficiently different from each other from a frequency range of about 1-1z. Therefore, in this embodiment, the stirring body 24 having the stirring blades 22 performs a fibrillating motion in a complicated vibration mode by the composite alternating current supplied from both the alternating current sources 60 and 62. , it is possible to perform an efficient stirring action. Normally, the stirring body 24 undergoes a large axial movement along its axis due to the compound mode vibration and a small movement caused by the high frequency AC source 62.
This is performed in combination with the movement in the C direction, thereby achieving uniform stirring. Basically, the movement of the vibration source 28 is a reciprocating motion along the axial direction of the stirring body 24, but depending on the unsprung cart side of the diaphragm 30, that is, the mass of the stirring body 24 and the structure of the shaft support, a fibrillation mode is generated. It is possible to set the stirring blade 24 not only in the axial direction but also in a mode that gives a predetermined twist to the stirring body 24, and the stirring blade 24 shown in FIG. 2 can also be driven in the circumferential direction according to the desired mode. be able to. As described above, according to this embodiment, by supplying a predetermined composite alternating current to the movable coil 40 of the vibration source 28, the stirring body 24 or the stirring blade 22 is rotated in the axial direction or circumferential direction within the conduit 10. Fibrillating movement in mode, conduit 1
It is possible to efficiently stir and mix the mixed fluids Δ and B that are guided to zero by not only the static stirring action of the stirring blade 22 but also by its fibrillating motion. In the embodiments described above, an electromagnetically driven vibration source using a movable coil is shown, but it is also possible to fix the coil and arrange the permanent magnet on the movable side. In addition, in the embodiment described above, the vibration source is electromagnetic drive = 1
2 = consists of a dynamic vibration source, but it is also possible to use an ultrasonic vibration source in the present invention. In the case of an ultrasonic vibration source, the diaphragm 30 shown in FIG.
A piezoelectric vibrator made of barium titanate or the like is attached to the diaphragm 30, and by applying a driving voltage directly to the piezoelectric vibrator, the diaphragm 30 vibrates due to the piezoelectric effect of the piezoelectric vibrator, which is transmitted to the stirring body 24. The desired mixing and stirring action can be achieved. FIG. 3 shows another embodiment of the mixer device according to the present invention, which includes a conduit 110 and a stirring body 1.
24 are each connected to a separate vibration source. In the figure, the conduit 110 is shown with its branches 112 and 11
The fluids to be mixed are guided from the conduits 110 as shown by arrows Δ and B, and the above-mentioned agitator 12 is provided in the conduit 110.
4 is supported so that it can be fibrillated. In the embodiment, the stirring body 124 is provided with different stirring blades 122a and 122b in its axial direction, and the introduced fluids Δ and B are sequentially roughly and finely stirred and mixed. In this embodiment, a coil 172 is fixed to the outer tube of the conduit 110 via a holder 170, and a relatively low frequency alternating current is supplied to this coil 172 from a drive source 174. . On the other hand, on the substrate side of the device, the
A ring-shaped magnet 176 is attached to the yoke 1 at a position close to the yoke 72.
78 are installed together with the drive source 1 due to the electromagnetic action between the coil 172 and the ring-shaped magnet 176.
It will be appreciated that in accordance with the alternating current from 74, conduit 110 fibrillates at a relatively low frequency. On the other hand, the stirring body 124 has an ultrasonic horn 180 attached to its shaft.
The ultrasonic horn 182 has ultrasonic transducers 182 and 184 attached to its base, and the ultrasonic transducers 182 and 184 from the ultrasonic oscillation source 186 are connected to both transducers 182 and 1.
84, the ultrasonic horn 180
The ultrasonic wave is transmitted to the ultrasonic vibrator stirring body 124, and each stirring blade 122a, 122b of the stirring body 124 can be covered with a fibrillating motion at high frequency. Therefore, according to this embodiment, by combining the coarse low frequency vibrations of the conduit 110 and the fine high frequency vibrations of the stirring body 124, it is possible to obtain a stirring action of the composite top rod suitable for stirring. As described above, according to the present invention, two or more different types of vibrations are applied to the conduit and stirring body of the Mikina device, and in the embodiments, the vibrations are shown as ultrasonic and electromagnetically driven vibrations. However, it is also possible to use any other vibration means such as motor rotation for these vibrations in the present invention. Furthermore, the two or more different types of vibration may be provided by applying two types of electrical supply signals to a single vibration source, or by supplying one type of vibration to a single vibration source continuously or intermittently. It is also possible to apply the signal while changing its frequency. Further, in the present invention, two or more types of vibration sources may be provided, and each may be connected to the conduit or the stirring body alone or separately. [Effects of the Invention] As explained above, according to the present invention, a vibration source imparts compound fibrillation motion to the stirring body, which is a stationary stirring element, disposed in the conduit and to the conduit, thereby causing the fluid to flow. When the stirring IY blade repeats division and merging to perform a static stirring action, the compound fibrillation motion imparts a desired vibration to the fluid,
As a result, the effect of the static stirring mixing action can be significantly enhanced, and a mixing device can be obtained which is particularly useful for mixing fine particles.
