2. Description of the Related Art In a conventional agitation processing apparatus having a single cylindrical container, a single-axis system having one rotating shaft is usually used for a single cylindrical container, and a two-shaft system having two rotating shafts In the case of the method, it is general that the number of cylindrical containers is also two. As an example of this, the present applicant has proposed that a biaxial multi-disc reactor (Japanese Patent Application No.
No. 0-075923) and a self-cleaning reactor (Japanese Patent Application No. 47-59211).

[0003]

The conventional uniaxial type agitation processing device described above has a lower manufacturing cost than the biaxial type agitation processing device, but when the processing substance becomes a highly viscous substance, the processed product becomes a stirring blade or the like. However, there is a problem in that a sufficient stirring and mixing cannot be performed due to the co-rotation phenomenon.

In order to solve this problem, two stirring shafts are provided, and two cylindrical containers are also provided along with the stirring shafts, and each of the rotating shafts rotates in the same or different directions. However, there is a concern that the initial cost is high and the practicability is low for the treatment of substances whose added value of the product is not so high.

The present invention is intended to provide a stirring treatment device which can solve the above problems of the conventional stirring treatment device.

[0006]

In view of the problems of the above-mentioned conventional stirring processing apparatus, the present inventors have made various studies and have a plurality of stirring blades that rotate independently in a single cylindrical container. Install them at the same speed or different speed,
We have found an agitator with separate rotating shafts that rotate in the same or different directions.

That is, the agitation processing apparatus of the present invention comprises a cylindrical container having an inlet and an outlet of a processed material, and a plurality of pillars installed inside the container and concentrically with the container with a slight gap therebetween. An arm, a hollow first rotation shaft connected to the columnar arm and installed on the axis of the container, and an opening formed in the axis core portion substantially perpendicular to the columnar arm and spaced apart from each other; A plurality of discs, a mesh wire mesh attached to a portion other than the opening of the shaft core portion on the disc, and a second rotation installed on the shaft core of the container so as not to contact the discs. An axis and a plurality of plate-shaped stirring blades mounted substantially perpendicular to the second rotating shaft and provided between the circular plates with a slight clearance between the circular plates, and the second rotating shaft And the first rotating shaft are rotated separately.

[0008]

According to the present invention, in the cylindrical container, the plurality of columnar arms rotate together with the disc having the mesh-like wire mesh attached thereto in a state of being close to the inner wall surface of the cylindrical container around the axis of the cylindrical container. Also, the plurality of plate-shaped stirring blades rotate independently of the columnar arm in a plane perpendicular to the axis of the container without contacting with the mesh-like metal net mounted on the disk. As a result, the processed material in the container is agitated and mixed.

Further, since the plurality of columnar arms and the plurality of plate-shaped stirring blades are independently rotated, and therefore, they can be rotated at the same speed or different speeds, the same direction or opposite directions, By adjusting each rotation direction and rotation speed, it is possible to prevent the processed material from rotating together with the disc and the plate-shaped stirring blades, to perform sufficient stirring and mixing, and to obtain an appropriate stirring and mixing state. You can

Further, the columnar arm and the members such as the plate-shaped stirring blades are housed in a single cylindrical container, so that the structure is simple and the manufacturing cost thereof is low.
