[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view of the mixing and discharging apparatus of the present invention. This apparatus includes a vertical support 1, a rotary shaft 2 supported horizontally on the support 1, and a lid member 3 fixed to the rotary shaft 2. The rotating shaft 2 can rotate in the directions of arrows A and B in the figure, can move up and down in the direction of arrow C, and can turn in the direction of arrow D.
[0009]
The lid member 3 has a funnel shape composed of a conical main body 31 and a discharge port 32 formed at the top of the main body 31. The discharge port 32 can be opened and closed by a lid 321. The lid member 3 is fixed to the rotating shaft 2 so that the funnel is erected. A fastener 33 is attached to the opening peripheral edge of the main body 31.
[0010]
2 is a view taken in the direction of arrow II in FIG. 1, and FIG. 3 is a longitudinal sectional view of the lid member 3 in FIG. 1, corresponding to a section taken along line III-III in FIG. A baffle member 4 is provided in the internal space of the main body 31. The baffle member 4 includes three baffle tools 41 extending horizontally and evenly from the center of the main body 31 to the inner wall. That is, each baffle tool 41 extends horizontally from the center of the main body 31, the tip abuts against the inner wall of the main body 31, and the adjacent baffle tools 41 are spaced by 120 °. As shown in FIGS. 3 and 4, the baffle tool 41 is a plate body configured in a V-shaped vertical section, and the V-shape is open to the discharge port 32 side.
[0011]
Next, the operation of the mixing and discharging apparatus having the above configuration will be described. First, as shown in FIG. 5, the lid member 3 of this apparatus is set so that the funnel is turned down, and, for example, a granulation tray 5 is brought underneath. As described above, the granulating tray 5 is taken out from the fluidized bed granulating apparatus while containing the granular material obtained by the fluidized bed granulating apparatus. Then, the upper opening of the granulation tray 5 is closed by the main body 31 of the lid member 3, and in this state, the main body 31 and the granulation tray 5 are fastened by the fastener 33. That is, the lid member 3 is attached and fixed to the granulation tray 5 as a lid. The granulation tray 5 is provided with a fastener receiver (not shown). As the fastener 33 and the fastener receiver, those described in Japanese Patent Application Laid-Open No. 9-177728 by the applicant of the present application can be used.
[0012]
Then, as shown in FIGS. 6 and 7, the rotary shaft 2 is rotated in the direction of arrow A, for example, at 3 rpm for 5 minutes, and then in the direction of arrow B, similarly at 3 rpm for 5 minutes, and the lid member 3 is moved to the granulation tray. Rotate while holding 5. During this rotation operation, the granular material in the granulation tray 5 is mixed as follows.
[0013]
That is, during the rotation operation, the granular material in the granulation tray 5 moves back and forth between the granulation tray 5 side and the lid member 3 side. Part of the granular material 10 that has come to the discharge port 32 side of the lid member 3 is accumulated in the V shape of the baffle tool 41 as shown in FIG. 8, and the rest moves to the granulation tray 5 side. And the granular material 10 collected in the V-shape of the baffle tool 41 flows in the V-shape during the rotation operation from the state of FIG. 6 to FIG. That is, in the rotation in the direction of arrow A, as indicated by the arrows in FIG. 9, it flows from both sides in the axial direction of the rotating shaft to the central portion, and in the rotation in the direction of arrow B, from the central portion as indicated by the arrows in FIG. It flows to both sides in the axial direction of the rotating shaft. 6 to 7, the powder 10 accumulated in the baffle tool 41 spills and moves to the lid member 3 side, and the powder 10 that has come to the granulation tray 5 side. 11, 12, and 2, as shown by an arrow E in FIG. 2, the baffle tool 41 is divided on both sides and moves to the lid member 3 side. In this way, the powder particles not only simply go back and forth between the granulation tray 5 side and the lid member 3 side, but part of them are stored in the baffle tool 41 and moved to the granulation tray 5 side. Is blocked, flows in the V-shape of the baffle tool 41, or is divided into both sides of the baffle tool 41 when moving to the lid member 3 side, so that the mixing efficiency is greatly improved.
[0014]
The powder particles thus mixed are discharged from the discharge port 32 by setting the lid member 3 as shown in FIG. 13 and opening the lid 321. At the time of this discharge, the granular material flows down while being divided on both sides of the baffle tool 41, so that it is discharged without segregation.
[0015]
Thus, according to the mixing and discharging apparatus having the above-described configuration, the powder particles in the granulating tray 5 are efficiently mixed and then discharged without segregation.
[0016]
In addition, as long as the baffle tool 41 does not interfere with mixing of a granular material, four or more may be sufficient.
[0017]
Moreover, as a baffle member, you may use the thing shown in FIG.14 and FIG.15. 14 is a diagram corresponding to FIG. 2, and FIG. 15 is a diagram corresponding to FIG. The baffle member 6 includes two substantially parallel plates 61 and 62 that are horizontally provided in the main body 31. The plate 61 is larger than the plate 62. Each of the plates 61 and 62 is in contact with the inner wall of the main body 31 only at the edges on both sides in the extending direction (arrow F direction). Further, as shown in FIG. 15, the surfaces of the plates 61 and 62 are inclined by an angle α with respect to the horizontal plane. Further, the passing direction of the plates 61 and 62 is inclined by an angle β with respect to the axial direction of the rotary shaft 2.
[0018]
Also by the lid member 3 having such a baffle member 6, the powder particles are efficiently mixed and then discharged without segregation. That is, during the rotation operation, when the state shown in FIGS. 7 to 6 is reached, a part of the granular material 10 that has come to the discharge port 32 side of the lid member 3 is shown in FIG. The movement to the granulation tray 5 side is hindered by 62 and the movement is delayed, and the rest moves smoothly to the granulation tray 5 side through the gaps between the plates 61 and 62 and the inner wall of the main body 31. On the other hand, when the state shown in FIGS. 6 to 7 is reached, part of the granule 10 on the granulation tray 5 side is prevented from moving toward the lid member 3 by the plates 61 and 62 as shown in FIG. The remaining portion moves slowly, and the remaining portion smoothly moves toward the lid member 3 through the gap between the plates 61 and 62 and the inner wall of the main body 31. Moreover, the granular material moves while being largely divided by the plates 61 and 62. In this way, part of the granular material moves with a delay, or the granular material moves while being largely divided, so that the mixing efficiency of the granular material is improved. Further, when discharging the granular material, since the granular material flows down while being largely divided by the two plates 61 and 62, it is discharged without being segregated.
[0019]
Moreover, the container of the granular material to mix is not restricted to the granulation tray 5 of a fluidized-bed granulation apparatus, What is necessary is just an open container which can attach the cover member 3 as a lid | cover.
[0020]
【The invention's effect】
According to the first aspect of the invention, the baffle member prevents not only the powder particles from moving back and forth between the container side and the lid member side, but also a part of the powder particles moving to the container side. In addition, since the granular material that moves to the lid member side can be divided on both sides of the baffle tool, the granular material can be mixed very efficiently. Moreover, since it can be made to flow to a discharge port, dividing a granular material into the both sides of a baffle tool, when discharging a granular material from a discharge port, it can discharge | emit, without segregating a granular material.
[0021]
According to the second aspect of the present invention, not only the powder body is moved back and forth between the container side and the lid member side, but also a part of the powder body is delayed and moved by the baffle member. Since the particles can be moved while being roughly divided, the particles can be mixed very efficiently. Moreover, since it can be made to flow to a discharge port, dividing a granular material by a baffle member when discharging a granular material from a discharge port, it can discharge | emit, without segregating a granular material.
[0022]
According to invention of Claim 3, the freedom degree of the height position and place which can discharge the mixed granular material can be expanded.
