Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluid mixing device, and more particularly to a fluid mixing device that can effectively mix several types of fluids without using mechanical power.

Numerous variants of devices serving the same purpose have already been proposed and are known.

However, with conventional devices, devices with relatively simple structures do not provide sufficient mixing effects, and devices with high mixing effects not only have complicated structures and are expensive;
The drawback was that the entire device had to be made larger. The object of the present invention is to avoid the above-mentioned drawbacks of conventional devices, to be simple in structure, to be manufactured at low cost, to be miniaturized as a whole, to take up little installation space, and to exhibit high mixing effects. An object of the present invention is to provide a fluid mixing device.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a cylindrical casing, which has flanges 2, 2 protruding toward the outer circumference at openings on both sides, and end plates 5, 6 equipped with an inlet 3 and an outlet 4, which can be attached and detached with bolts and nuts. It is installed on. T (Ta~7f) is a plurality of flow guiding units for mixing fluids arranged inside the hollow of the casing 1. As shown in FIGS. 2 and 3, the flow guiding unit 7 has polygonal small chambers B with open fronts on opposing surfaces.
A set of two large and small disks 9 and 10 in which a large number of disks a and 8b are arranged in a honeycomb shape is formed by concentrically superimposing them. Note that the small chambers Ba and 8 may be rhombic, or in short, may be polygonal. The large-diameter disk 9 has an outer diameter close to the inner diameter of the casing 1, and has a communication hole 11 in the center.
is drilled. The outer diameter of the small-diameter disk 10 is spaced apart from the inner peripheral surface of the casing 1 to form a flow passage 12 therebetween. As shown in FIG. 3, the small chambers Ba of the large-diameter disk 9 and the small chambers 8b of the small-diameter disk 10 are arranged at different positions so that each small chamber communicates with a plurality of other small chambers facing each other. ing.

These flow guide units 7 are arranged in parallel in the hollow interior of the casing 1 so that the disks having the same diameter are adjacent to each other and are perpendicular to the axial direction of the casing 1. In addition, casing 1
Large-diameter disks 9 are disposed on both sides so that the flow holes 11 correspond to the inlet 3 and outlet 4 of the main body. Further, it is desirable that the large-diameter disk 9 and the small-diameter disk 10 of the flow guide unit 7 are integrated by bonding the front portions of the small chambers that are joined to each other. The device of the present invention configured as described above feeds two or more different types of fluids into the hollow interior of the casing 1 from the inlet 3 of the casing 1 using appropriate pressure feeding means.

Therefore, the fluid sent into the hollow interior of the casing 1 flows through the first flow guiding unit 7 (7) as shown by the arrow in FIG.
The small-diameter disk 10 reaches the inside from the communication hole 11 in a).
They are prevented from moving straight, change direction, and move in a radially dispersed and meandering manner from the center toward the outside through the small chambers 8a and 8b that communicate with each other. When the fluid moves through each of the small chambers 8a and 8b, it collides with the plurality of side walls that constitute the small chambers 8a and 8b, causing the flow to reverse in a complicated manner and become a vortex. In this way, the fluid that reaches the inner circumferential surface of the casing 1 while repeating dispersion, reversal, and vortex action by passing through the first flow guiding unit 7 (7a) The small chambers 8a, 8b of the second flow guide unit 7 (7b) enter from the flow path 12 formed by the inner circumferential surface and the small-diameter disk 10, and the dispersion, reversal, and vortex effects as described above are generated. While repeating this process, they are assembled in the center, and the flow holes 11 are opened again.
It enters the inside of the third flow guiding unit 7 (7c).

Then, it passes through each of the small chambers 8a and 8b again, radially dispersing outward from the center, repeating meandering and sequentially moving inside the flow guide unit, and is finally discharged from the outlet 4. Therefore, according to the device of the present invention, the flow guiding unit 7 (
7a to 7f), and in the process of moving through the small chambers 8a and 8b facing each other in a communication manner, the fluid is mixed by dispersion, inversion, and vortex action, and then redispersion and aggregation are repeated radially. This mixes the mixing fluids and provides much more effective mixing than any conventional mixing device.

Another embodiment shown in FIGS. 5 and 6 is a flow guiding unit 7
A protrusion 13 is provided at the center of the bottom surface of each of the small chambers 8a, 8b, excluding the central portion of the two large and small disks 9, 10 constituting the disk, which is lower than the height of the top surface of the small chambers 8a, 8b.

Thereby, turbulence can be actively caused in the fluid flow, and the layer mixing effect can be enhanced. Also,
The protrusions 13 increase the shearing force of the fluid during convection when the fluid flows into the chamber.

Further, by making the projections 13 gradually smaller toward the center, the volume of each chamber is made uniform, and smooth fluid flow is ensured. As described above with respect to the embodiments, according to the fluid mixing device of the present invention, fluid is mixed by dispersion, inversion, and vortex action in each small chamber of the flow guide unit, and further from the center of the flow guide unit to the outside or Since it performs radial mixing by alternately repeating redispersion and aggregation radially from the outside to the center, a much higher mixing effect can be obtained compared to conventional mixing devices.

Further, according to the present invention, since a plurality of flow guide units serving as mixing elements are arranged in parallel in the hollow interior of the casing so as to be orthogonal to the axial direction of the casing, the entire device, especially the fluid flow direction, can be made very short. Therefore, it is possible to provide a fluid mixing device that is extremely practical in terms of manufacture and use without increasing the installation space. Furthermore, a long flow distance can be obtained in a small volume, making fluid mixing very efficient.
