With this configuration, when the payload upper plate 110 and the payload lower plate 120 are excited and move up and down, the eighth spring 148 finally moves the payload upper plate 110 within a predetermined angle range. It can be rotated repeatedly clockwise and counterclockwise. For example, the payload upper plate 110 may rotate 5° in a clockwise direction and 5° in a counterclockwise direction, and mixing performance may be further improved by performing such rotational motion in parallel with the vertical vibration.

As the intermediate mass ring 150 moves up and down, the seventh springs 147 perform tension and compression movements between the intermediate mass ring 150 and the lower fixing ring 170, and the payload lower plate 120 is As they move up and down, the eighth springs 148 perform compression and tension movements between the payload lower plate 120 and the lower fixing ring 170.

Hereinafter, a flow analysis result showing the effect of the mixing result in which the mixing object container 2 is moved up and down and rotated 5° clockwise and rotated 5° counterclockwise around a reference angle will be described.

ANSYS FLUENT R18.2 was used as the analysis program, and each solid particle was implemented and analyzed as a fluidized bed in order to realize the mixing phenomenon of the powder in the mixing object container (2) of the vibration mixing device, and a dynamic mesh (Dynamin Mesh) through UDF ) Technique and moving mesh technique were used.

8 is a view showing an analysis object of the vibration mixing device according to the first embodiment of the technology disclosed in the present specification, and FIG. 9 is a diagram used in the analysis of the vibration mixing device according to the first embodiment of the technology disclosed in the present specification. It is a diagram showing a model used to calculate the maximum packing limit of a fluid, FIG. 10 is a diagram showing the properties of an analysis object of the vibration mixing device according to the first embodiment of the technology disclosed in the present specification, and FIG. 11 is It is a diagram showing the motion conditions used in the analysis of the vibration mixing device according to the first embodiment of the technology disclosed in the present specification.

The shape of the object to be analyzed was modeled as a cylindrical structure with a diameter of 110 mm and a height of 120 mm, and the internal fluid was composed of air, solid 1, and solid 2. The subject of interpretation is as follows.

(1) Example: Up and down movement + left and right repetitive rotation movement

(2) Comparative Example 1: vertical motion

(3) Comparative Example 2: Up and down motion + one-way rotational motion (The mixture object container is fixed to the rotating plate installed on the payload upper plate and rotated in one direction)

(4) Comparative Example 3: Exercise using an internal impeller

When looking at the conditions of the properties of the object to be analyzed, the Euler model, which calculates each phase with each equation, was used, and a granular model that calculates the solid particles as a fluidized bed to realize the mixing phenomenon between solids was used. I did. The packing limit between particles was calculated through a volume ratio occupied by particles within the same volume in a simple cubic method as shown in FIG. 9. The viscosity value of each particle was applied based on the viscosity value of water in a liquid state, and was calculated by the following equation, and the result is shown in FIG. 10.

Maximum Packing Limit = (solid volume)/(fluid volume + solid volume)

Looking at the motion conditions for analysis, the vertical motion condition is a condition in which motion has an amplitude of 3.5mm (total 7mm) up and down with a frequency of 60 Hz, and the left and right rotation motion condition is a frequency of 60 Hz left and right with respect to the central axis. It is a condition to move as much as 5 degrees of amplitude (total of 10 degrees), and the condition of rotational motion is a condition in which the rotating plate or impeller rotates clockwise at a rotational speed of 500 RPM based on the central axis. Each exercise condition is summarized in FIG. 11.

Looking at the boundary conditions for the analysis, the flow field was composed of a closed system, and a No-Slip condition was applied to all walls, and the fluidized bed was composed of a total of three fluidized beds, and gas (40%) from the top. , Solid 1 (30%), Solid 2 (30%), and the flow field of Comparative Example 3 with an internal impeller was considered so that the volume ratio of Solid 1 and Solid 2 could each account for 30%.

12 is a diagram illustrating a location of a monitoring point to collect analysis result data of the vibration mixing device according to the first embodiment of the technology disclosed in the present specification.

In this analysis, as shown in Fig. 12, a total of 25 monitoring points in the mixed object container 2 were designated to collect the analysis result data, and each monitoring point moved in the same direction as the movement direction of the mixed object container 2 And, the data of each monitoring point was measured based on the volume average value of a cube having a length of 1.5 mm.

The monitoring point may be assigned an identification code as shown in FIG. 13. In Examples, Comparative Examples 1 and 2, as shown in Fig. 13(a), there are 5 horizontal monitoring points, and identification codes of 1 to 5 are assigned from the center toward the outside. In contrast, in Example 3, as shown in Fig. 13(b), there are four transverse monitoring points due to the central impeller, and there is no central transverse monitoring point. Accordingly, in Example 3, identification codes 1 to 4 are assigned from the center toward the outside. There are 5 monitoring points in the vertical direction, and identification codes of A, B, C, D, E are assigned from the bottom to the top.

14 shows a change in volume fraction over time in Example, FIG. 15 shows a change in volume ratio over time in Comparative Example 1, and FIG. 16 is a volume ratio over time in Comparative Example 2 And FIG. 17 shows the change of the volume ratio over time of Comparative Example 3.

As shown in FIG. 14, in the embodiment, mixing occurs within about 0.7 seconds, and from about 2.5 seconds thereafter, there is a difference in the value of the volume ratio for each position due to the influence of left and right rotation, but the difference gradually increases until about 6 seconds. It decreases, and the volume ratio does not have a big difference after 6 seconds. While the volume ratio converges, the amplitude is not large, so it can be seen that the mixing is performed to have the same volume ratio value at all monitoring points.Compared with Comparative Examples 1 to 3, it is confirmed that the mixing is most evenly proceeding. .

As shown in FIG. 15, in Comparative Example 1, mixing occurs within about 1.5 seconds, and after 1.5 seconds, Solid 1 has an even distribution, and Solid 2 has a difference in volume ratio value for each position due to the effect of vertical motion, After a certain time, the difference gradually decreases. However, in Solid 2, it is confirmed that the volume ratio values at the monitoring points show a difference while the volume ratio converges, and accordingly, it is confirmed that even mixing does not proceed.

As shown in Fig. 16, in Comparative Example 2, mixing occurs within about 1.5 seconds, and in the case of Solid 2 after mixing, the difference in volume ratio is repeatedly changed, and the volume ratio value tends to change rapidly from about 6 to 7 seconds. As a result, it is confirmed that even mixing is not achieved. This is because the influence of mixing due to rotational motion is greater than that of vertical motion, and it is judged that relatively heavy particles of Solid 2 are concentrated toward the wall surface like the centrifugal separator method.

As shown in FIG. 17, in Comparative Example 3, mixing occurred within about 2 seconds, and the volume ratio value of Solid 2 had a repetitive change until 5.5 seconds before, and the volume ratio of Solid 2 for each monitoring point from 6 seconds later. Since the values have a large difference, it is confirmed that even mixing is not achieved. It is judged that the rotation of the impeller acts like a centrifugal separator, and the particles of Solid 2, which are relatively heavy particles, are concentrated toward the wall.

18 shows the time taken for the volume ratio to reach the set value in all areas in the container of the object to be mixed as an analysis result.

Looking at the initial mixing, all samples had an even mixing distribution within about 2 seconds, and the value of the volume ratio with even mixing for all areas in the container to be mixed was 0.119 for Solid 1, and 0.160 for Solid 2. to be.

In the case of the examples, the initial mixing had the fastest mixing time over the entire area. Until the initial mixing, the particles had an even distribution, but in the case of Solid 2, which is a relatively heavy particle, there was a difference in the volume ratio value due to the motion of the mixer.

In the case of Comparative Example 1, there was a difference in the volume ratio value due to the particle motion of the solid 2, but due to the even balance of the vertical motion and the left and right rotational motion, it had an even particle distribution over the entire area of the mixed object container.

In the case of Comparative Example 2, the particles of Solid 2 tend to be concentrated on the wall surface by rotational motion, which tends to become more severe as time passes.

In the case of Comparative Example 3, particles of the solid 2 were concentrated on the upper wall of the mixer by rotational motion, so that the difference in volume ratio values for all areas was large.

In conclusion, vibration mixing showed up to 5.1 times faster even mixing performance than internal impeller mixing, and rotational motion had a great influence on mixing particles of internal powder, and repetitive left and right rotational motion was more than one-way rotational motion. It had a better effect on all areas.
