It can be turned in the direction of arrow D.

The lid member 3 includes a conical main body 31 and a main body 3.
1 and a discharge port 32 formed at the top portion. The outlet 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 stands upright. A fastener 33 is attached to the periphery of the opening of the main body 31.

FIG. 2 is a view taken in the direction of the arrow II in FIG. 1, and FIG. 3 is a longitudinal sectional view of the lid member 3 in FIG. 1, which corresponds to a section taken along the line III-III in FIG. The baffle member 4 is provided in the internal space of the main body 31. The baffle member 4 is composed of three baffles 41 extending horizontally and evenly from the center of the main body 31 to the inner wall. That is, each of the baffles 41 extends horizontally from the center of the main body 31, and the tip thereof abuts on the inner wall of the main body 31, and the adjacent baffles 41 are spaced apart by 120 °. As shown in FIGS. 3 and 4, the baffle member 41 is a plate body configured in a V-shaped vertical cross section.
The V-shape is open to the outlet 32 side.

Next, the operation of the mixing / discharging apparatus having the above-described structure will be described. First, as shown in FIG. 5, the lid member 3 of the present apparatus is set so that the funnel is turned down, and for example, a granulation tray 5 is brought below the lid. Granulation tray 5
As described above, is obtained by taking out the granular material obtained by the fluidized-bed granulator from the fluidized-bed granulator while containing the powdered material. 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 is closed by the fastener 33.
And the granulation tray 5 are fastened. 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 JP-A-9-177728 by the present applicant can be used.

Then, as shown in FIGS. 6 and 7, the rotating shaft 2 is rotated in the direction of arrow A, for example, at 3 rpm for 5 minutes, and subsequently in the direction of arrow B, at 3 rpm for 5 minutes.
The lid member 3 is rotated while holding the granulation tray 5.
During this rotation operation, the granules in the granulation tray 5 are mixed as follows.

That is, during the rotation operation, the granulating tray 5
The powdery material in the middle goes back and forth between the granulation tray 5 and the lid member 3 side, but when it comes to the state shown in FIGS. 7 to 6, it comes to the discharge port 32 side of the lid member 3. As shown in FIG. 8, a part of the powder particles 10 accumulates in the V-shape of the baffle tool 41,
The rest moves to the granulation tray 5 side. Then, the granular material 10 accumulated in the V-shape of the baffle 41 flows in the V-shape during the rotation operation from the state shown in FIG. 6 to the state shown in FIG. That is, in the rotation in the direction of the arrow A, as shown by the arrow in FIG.
As shown by an arrow during zero, the fluid flows from the central portion to both axial portions of the rotating shaft. When the state shown in FIG. 6 is changed to the state shown in FIG.
The granular material 10 accumulated in the baffle 41 is spilled and moved to the lid member 3 side, and the granular material 1
Numeral 0 is divided on both sides of the baffle 41 and moves toward the lid member 3 as shown by the arrow E in FIGS. In this manner, the powder and granules not only move back and forth between the granulation tray 5 side and the lid member 3 side, but also partly accumulate in the baffle 41 and move to the granulation tray 5 side. Blockage, flow in the V-shape of the baffle 41,
When moving to the side, it is divided on both sides of the baffle tool 41, so that the mixing efficiency is greatly improved.

The thus mixed powder is discharged from the discharge port 32 by setting the cover member 3 as shown in FIG. 13 and opening the cover 321. At the time of this discharge, the granular material flows down while being divided on both sides of the baffle tool 41, and is discharged without segregation.

As described above, according to the mixing / discharging apparatus having the above-described structure, the granules in the granulating tray 5 are efficiently mixed and then discharged without segregation.

The number of the baffle tools 41 may be four or more as long as the mixing of the powder and granules is not hindered.

As the baffle member, the baffle member shown in FIGS. 14 and 15 may be used. FIG. 14 shows FIG.
FIG. 15 is a diagram corresponding to FIG. The baffle member 6 is composed of two substantially parallel plates 61 and 62 that extend horizontally within the main body 31. The plate 61 is larger than the plate 62. Only the edges on both sides of the plates 61 and 62 in the bridging direction (the direction of arrow F) are in contact with the inner wall of the main body 31. The surfaces of the plates 61 and 62 are inclined by an angle α with respect to the horizontal plane as shown in FIG. The direction in which the plates 61 and 62 are provided is inclined by an angle β with respect to the axial direction of the rotating shaft 2.

Even with the lid member 3 having such a baffle member 6, the particles are efficiently mixed and then discharged without segregation. That is, when the state shown in FIG. 7 to FIG.
As shown in FIG. 16, a part of the granular material 10 that has come to the side is delayed by the movement to the granulation tray 5 side by the plates 61 and 62, and the rest is moved to the respective plates 61 and 62. 62 and body 3
1 smoothly moves to the granulation tray 5 side through the gap with the inner wall. On the other hand, when the state shown in FIG. 6 is changed to the state shown in FIG. 7, a part of the granular material 10 on the granulation tray 5 side is prevented from moving toward the lid member 3 by the respective plates 61 and 62 as shown in FIG. The remaining parts move with a delay, and the rest smoothly move to the lid member 3 side through the gaps 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. As described above, since a part of the granular material moves with a delay or the granular material moves while being largely divided, the mixing efficiency of the granular material is improved. Further, when discharging the granular material, the granular material flows down while being largely divided by the two plates 61 and 62, and is discharged without segregation.

Further, the container of the powdery and granular materials to be mixed is not limited to the granulation tray 5 of the fluidized bed granulator, but may be any container that can be opened upwardly to which the lid member 3 can be attached as a lid.

[0020]

According to the first aspect of the present invention, it is possible to not only move the granular material back and forth between the container side and the lid member side, but also to move a part of the granular material to the container side. Can be blocked by a baffle member, or the powdery material moving toward the lid member can be separated on both sides of the baffle device, so that the powdery material can be mixed very efficiently. Further, when discharging the granular material from the discharge port, the granular material can be flown to the discharge port while being divided on both sides of the baffle tool, so that the granular material can be discharged without segregation.

According to the second aspect of the present invention, the powder and granules are not only moved back and forth between the container side and the lid member side, but are also moved with a baffle member by delaying a part of the powder and granules. Since the powder and the granular material can be moved while being largely divided, the granular material can be mixed very efficiently. Further, when discharging the granular material from the discharge port, the granular material can be flowed into the discharge port while being largely divided by the baffle member, so that the granular material can be discharged without segregation.

According to the third aspect of the present invention, the degree of freedom of the height position and the place where the mixed powder and granular material can be discharged can be expanded.
