BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below based on the embodiments shown in the drawings. For the sake of convenience, the same components will be described with the same reference numerals. FIG. 1 is a side sectional view schematically showing a part of a vibrating stirring and mixing apparatus according to the present invention, FIG. 2 is a plan view showing the shape of stirring blades, and FIGS. 3 and 4 are cross-sections of the brush brush of FIG. FIG. 5 is a side view showing the surface shape, FIG. 5 is a plan view showing another embodiment of the brush portion, and FIG. 6 is a schematic configuration diagram showing a vibrating stirring and mixing apparatus (vibro mixer).

[0008]

Embodiment 1 As shown in FIGS. 1 and 6, a vibrating stirring and mixing apparatus V for mixing fluids (hereinafter referred to as vibromixer) is a substance to be mixed (hereinafter, referred to as vibrating mixer) in a tubular casing 1. (Referred to as a fluid), a fluid inlet 4 is provided below the fluid inlet 4, and an upper opening is an outlet 5 for ejecting the mixed fluid. Then, the fluid is press-fitted from the inflow port 4 by the liquid feeding means such as the pump P, passes through the inside of the casing 1, and is discharged from the discharge port 5. Inside the casing 1, a plurality of mixing chambers are defined by a partition plate 1a, and a stirring body 2 is inserted and arranged. The stirring body 2 drives a drive shaft 2a connected to a vibration source (vibrator) M. As a result, the casing 1 vibrates vertically in the longitudinal direction, and the fluid to be mixed is agitated and mixed while being circulated inside the casing 1. The stirring body 2 is the vibration source M.
The shaft 2a connected to the shaft 2a and the spiral blade 2b attached to the periphery of the shaft 2a generate a strong vortex due to its vertical vibration, and the fluid in the casing 1 can be suitably agitated and mixed. .

Here, the agitating member 2 is constructed by integrally connecting agitating blades 2b around the agitating member 2. The most characteristic feature of this embodiment is that, as shown in FIGS.
The point is that the brush portion 3 in which a plurality of brushes (protrusions) 3a are planted is formed at the outer peripheral edge of the stirring blade 2b. As shown in FIGS. 3 and 4, the brushes (protrusions) 3 a are arranged in a staggered pattern in the vertical direction of the stirring blade 2 b, and the brushes (protrusions) 3 a
The gap 3b between the a is formed in a crank shape vertically.

By the brush portion 3, the stirring and mixing in the casing 1 is favorably performed. This is probably because the vertical movement of the stirring blade 2b causes the mixed liquid to be finely divided when flowing between the brushes (protrusions) 3a, and a unique vortex flow is generated when flowing through the gaps 3b. . The gist of the present invention is that a brush portion is provided on the stirring blade 2b, and the shape and arrangement of the brush are arbitrary. For example, the cross-sectional shape of the brush is rectangular as shown in FIG.
A circular shape as shown in FIG. 4 may be used, and any of them can achieve a desired effect. Further, the arrangement of the brushes is also optional, but it is preferable to arrange the brushes in a zigzag pattern as in this embodiment.

According to the apparatus of the present invention, two or more kinds of substances, for example, a high-quality mixed substance of powder and liquid (a substance in which powder is uniformly dispersed and mixed in liquid) or high-quality water and oil are used. A mixed substance (emulsion) can be obtained. Further, when a gas is mixed with a liquid to generate bubbles, for example, it is effective for producing a whipped cream or the like in which air is finely mixed in a mixed substance.

FIG. 5 shows another embodiment of the brush portion. The same components as those of the first embodiment will be described with the same reference numerals.

[0013]

[Embodiment 2] In this embodiment, as shown in FIG. 5, the brush portion 3 is formed by bending a steel wire into two and forming the bent portion into an arc shape or a coil shape. Brush 3
a, and both ends thereof are planted around the periphery of the stirring blade.

[0014]

Since the present invention is constituted as described above, it has an excellent effect that the stirring efficiency and the mixing efficiency of the vibration type stirring and mixing apparatus (vibro mixer) can be improved.
