行なわれるのは第５図の従来例と同じである。1 Effect" The effect of the above configuration will be described with reference to FIG. 4. In FIG. The circle I! A vortex-like turbulent flow is generated at the upstream side S1 of f1s, and the first mixing occurs. The mixed fluid that has passed through the flow path formed along the outer periphery of the disk 6 and the surface of the cone body 7
As in the conventional example shown in FIG. 5, a vortex-like turbulent flow is generated again at the downstream portion S2 of the flow, and a second mixing is performed.

になる。However, in the case of the present invention, since the reinforcing rib 21 has a rectifying effect, the turbulent flow generated at the upstream portion S1 when passing through the reinforcing rib 21 is rapidly attenuated. Although the rectifying effect of the reinforcing ribs 21 does not directly restrict the generation of turbulent flow at the downstream section S2, the first mixing at the upstream section S1 of the disk 6 and the second mixing at the downstream section S2 of the cone 7 This will disrupt the synergistic effect of the two, resulting in a decrease in mixing efficiency. In other words, if the mixed fluid flows to the downstream part S2 of the cone body 7 while the turbulent flow at the upstream part Sl of the disk 6 is not eliminated, a synergistic effect on the mixing efficiency can be expected, but if the flow is rectified midway, this synergistic effect The effect will no longer be obtained. Furthermore, the turbulent flow at the downstream part S2 of the cone 7 is caused by the turbulent flow at the upstream part S1 of the disk 6.
Unlike the turbulent flow at The ratio of mixing between the flow (flow closer to the outer circumferential side in outer shell 9) and the inner flow (flow closer to the 8 glaze side in outer mantle 9) changes greatly.

体的に呈するものである。Therefore, in the present invention, the screw plate 22.22.degree. 22 imparts rotation to the mixed fluid that has passed through the reinforcing ribs 21.21.21. The rotation of the flow by this screw plate 22 is also a kind of turbulent flow, which itself has a mixing effect.
Since this screw plate 22 is disposed on the inner surface of the tapered pipe portion 9b, strong rotation occurs in the outer flow, which reduces the difference in mixing ratio with the inner flow described above. In the portion S2, the rotation by the screw plate 22 and the conventional turbulent flow overlap, resulting in a complex and efficient mixing as a whole.

) is set to approximately 1/4 of the inlet diameter (L1 1/4L) to prevent pressure fluctuations by keeping the flow passage cross-sectional area approximately the same, and the protrusion 6a locally reduces the flow passage cross-sectional area. This is to ensure that turbulent flow occurs due to collision at the upstream portion of the disk 6 due to narrowing of the disk.
Setting the distance (Ll) to 65% to 75% of 1 as described above consumes less energy for pumping the mixed fluid and can most efficiently obtain turbulent flow due to collision.

早くなり乱流を生起し易くしであることは無論である。Furthermore, the flange 2a on one side and the flange 2b on the other side
A large diameter portion 9a having a gap of approximately one-fourth of the inlet diameter between the discs 6, and a tapered pipe portion 9b narrowing toward the other flange 2b. It is equipped with a cloak 9. This large diameter portion 9a ensures a flow passage cross-sectional area that is approximately the same as that of the liquid guiding pipe 1. Further, although the tapered tube portion 9b is narrowed toward the other side flange 2b, which is the distal end side,
It goes without saying that the distance between the circumferential surface of the conical body 7 and the conical body 7 is gradually increased, so that the flow velocity along the conical body 7, in other words, the inner flow becomes faster and turbulence is more likely to occur. .

ることになるものである。The inner surface of the large diameter portion 9a of the mantle 9 and the disk 6 are connected by radial reinforcing ribs 21, 21, 21...
Further, a screw plate 22,
22.22... is fixed. The main purpose of this reinforcing rib 21 is to reinforce when disposing and fixing the disk 6, but if sufficient strength can be obtained, it may also be used for fixing the disk 6 instead of the support rod 4 as described above. , although not shown,
It may be made integral with the screw plate 22 or may be made alone at a certain angle with respect to the six hemlocks of the mantle 9 to have a screw function. That is, this reinforcing rib 21
can also serve the function of the screw plate 22, and in this case, the screw plate 22 can be omitted,
In other words, it is possible to omit the reinforcing rib 21 by having the tip side of the screw plate 22 connect the inner surface of the large diameter portion 9a and the outer peripheral surface of the disk 6. Note that the reason why the screw plate 22 is arranged on the inner surface of the large diameter portion 9a means that the inner end of the screw plate 22 does not touch the outer circumferential surface of the cone body 7 on the tip side of the cone body 7. to do,
By doing this, the mixed fluid is mixed uniformly throughout.

ある。r Effects of the Invention Since the present invention is as described above, the first mixing due to the turbulent flow that occurs at the upstream portion S1 of the disk 6 when it collides with the disk 6, and the inner flow when flowing along the cone 7. Not only is the fluid mixed efficiently with the second mixing caused by the turbulent flow generated in the downstream portion S2 of the cone body 7 when the fluid is accelerated, but the mixed fluid flowing through the tapered pipe portion 9b is entirely mixed by the screw plate 22. It is possible to provide a mixer for continuous mixing of fluids which is rotated and can perform complicated and efficient mixing as a whole by overlapping the mixing caused by the rotation itself and the second mixing.

低下を充分に補うものである。Furthermore, in the present invention, the fixation of the disk 6 is reinforced by the reinforcing ribs 21, so it has excellent durability, and the rotation of the mixed fluid by the screw plate 22 increases the flow velocity in the tapered pipe portion 9b, so that the second Mixing can be caused more reliably, and as a result, the reduction in mixing efficiency caused by the provision of the reinforcing ribs 21 can be sufficiently compensated for.

The chemicals used for the mixed material of domestic hardwood were air-dried bulbton, 31 kg of chlorine, 18 kg of alkali, 15 kg of sodium hypochlorite, and 3.5 g of chlorine dioxide, resulting in a product whiteness of 85 (Hunter display). , when using a mixer for continuous mixing of the fluid of the present invention, the amount of chlorine used is 27 kg.
The same product whiteness can be obtained with 16 kg of alkali.
・Product whiteness was the same standard with 15 kg of trisodium hypochlorite and 3.2 kg of chlorine dioxide, and as a result of chlorine mixing being done more appropriately and uniformly, the amount of chlorine itself used and the neutralization in the next stage were reduced. It was also possible to reduce the amount of alkal used for extraction and the amount of chlorine dioxide used in the final stage.
