And a flange portion 121a corresponding to the inner flange portion 12a1. As will be described later, in the filter portion 121, when the slurry or the like is filtered, the sintered metal portion 121c functions as a cake layer forming surface and the wire mesh portion 121b functions as a filtrate dividing portion.

Next, various processes performed by using the mixing dryer according to the present embodiment having the above-described structure will be described. In addition, here, a case where a slurry and some additives are introduced as an object to be processed (corresponding to the “slurry object to be processed” of the present invention) and a mixing process, a filtering process, and a drying process are performed explain.

<Mixing Treatment> In the mixing dryer according to the present embodiment, when mixing the slurry and the additives charged from the charging port 14, before mixing the slurry and the like depending on the properties of the slurry and the like. During or after the charging, the stirring blade 20, the auxiliary blade 30, and the ribbon blade 40 are rotationally driven via the driving means 15, the driving shaft 17, and the vertical shaft 18.

In the mixing / drying apparatus according to the present embodiment, the number of rotations of the blades 20, 30, 40 can be appropriately changed according to the property of the slurry, the processing amount, the processing time, etc. during the mixing process. Is configured. Further, the mixing and drying machine according to the present embodiment is configured so that the type, temperature, flow rate, etc. of the medium to be circulated in the outer jacket portion 19 can be changed as appropriate, so that the medium can be used even when the temperature control of the slurry or the like is required. This can be easily dealt with by adjusting the temperature and the like.

<Filtration Treatment> When the mixing treatment is completed and the filtration treatment is performed, air or an inert gas or the like is jetted from the pressurizing port 16 so that the inside of the container 100 has a predetermined pressure (for example, 0.1 MPa to 0). The blades 20, 30, 40 are rotationally driven in a relatively gentle manner under a pressure of 0.5 MPa. For example, the blades 20, 30, 40 are 5 rpm-60 r
Rotate at a rotation speed of about pm.

In the mixing dryer according to the present embodiment, when the blades 20, 30, 40 are rotated at an excessively high speed during the filtration process, the rotation causes the cake (solid component of the object to be treated) to be sintered metal. It may be pressed against the parts and cause clogging. On the other hand, when the filtration treatment is performed with the blades 20, 30, 40 stopped, the cake is laminated after the filtration treatment between the blades 20, 30, 40 or between the blades 20, 40 and the inner surface of the container body 10. Then, when it is rotationally driven again, an overload state occurs, and the drive means 15, the drive shaft 17,
The vertical shaft 18, the blades 20, 40, etc. may be damaged or malfunctioned. Therefore, in the present embodiment, the blades 20, 30 and 40 are rotationally driven while being relatively gently pressed to prevent the cake from being stacked on the blades and the like, while performing the filtering process.

Here, FIG. 4 is an enlarged view of a portion A in FIG. 1 in the case where the filtering process is performed using the mixing dryer according to the present embodiment. When the filtration process is performed in the container 100, as described above, the pressure port 16
By ejecting air or an inert gas from the container, the object to be processed is pressed outward from the center of the container 100 (in the direction of arrow B), and cake is formed on the sintered metal part 121c forming the filter part 121. C (solid component forming the object to be treated) is laminated. In addition, when the object to be processed is pressurized, the liquid component forming the object to be processed is changed to the sintered metal portion 121.
It reaches the wire mesh part 121b through the gap of c, and this wire mesh part 1
The filtrate is discharged to the outside of the mixing and drying machine as a filtrate through 21b, the opening 12b, the filtrate collecting section 122, and the filtrate discharging section 123. If the filtrate is a required product, a storage tank or the like (not shown) may be appropriately provided on the downstream side of the filtrate discharge section 123.

Further, the mixing and drying machine according to this embodiment is
Even during this filtration process, the properties of the slurry,
Depending on the processing amount or processing time, the blades 20, 30, 4
The number of rotations of 0 can be changed appropriately. Further, as described above, since the temperature inside the container 100 can be easily adjusted by appropriately changing the type, temperature, flow rate, etc. of the medium to be circulated in the outer jacket portion 19, the filtration process can be performed while controlling the temperature of the slurry or the like. Can be carried out.

<Drying Process> When the above filtering process is completed and the drying process is performed, the stirring blade 20, the auxiliary blade 30, and the ribbon blade 40 are connected via the drive means 15, the drive shaft 17, and the vertical shaft 18. By rotating the container 10,
0 Stir the cake laminated on the inner wall surface or the like. in addition,

Also in this drying process, the number of revolutions of the blades 20, 30, 40 can be appropriately changed depending on the properties of the cake or the required powder, the amount of treatment, the treatment time, and the like. When performing this drying process, the blades 20, 30, 40 rotate at a relatively low speed (for example, 3
A configuration in which it is rotationally driven at 0 rpm to about 90 rpm) is preferable. If it is driven to rotate at an excessively high rotation speed, problems such as vortexing and breakage of powder particles occur. Here, the vortex is a phenomenon in which powder or the like is scraped up to a high position in the vicinity of the inner peripheral surface of the container and deeply falls in the central part of the container.
