BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring granulator, and more particularly, to a stirring granulator in which a processed object and a binder are stirred together with a stirring blade in a tank, and granulated and pulverized are repeatedly formed to form a particulate matter of a desired particle size.

In general, in the stirring granulator, the powder-like processed material introduced into the tank is stirred while adding an appropriate amount of binder, and granulation and pulverization are repeated to form the processed material in the form of particles having an appropriate particle size.

In such a stirring granulator, a pair of upper and lower stirring blades are rotatably installed in the tank, and the stirring blades are subjected to stirring while applying shear and centrifugal force to the processed material and the binder, and the granulated and broken particles are repeated to repeat particles of desired particle size. It is supposed to form a shape.

Since a pair of upper and lower stirring blades are attached to the same rotating shaft and rotate in the same direction at the same rotational speed, a difference occurs in the centrifugal force and the shear force between the vicinity of the center of the tank and the vicinity of the inner wall, and the processed object is located in the center of the tank. This may stay or the processed material may stick to the inner wall surface of the tank.

In such a case, it becomes difficult to stir uniformly the whole processed material, and it becomes impossible to form the granular material of the uniform particle grade.

On the other hand, in order to solve the above problems, a pair of upper and lower stirring blades are rotatably installed in the tank, and each stirring blade is connected to a rotating shaft having a different rotation direction, and the lower stirring blade is rotated at low speed. At the same time, it is proposed that the upper stirring blade is rotated at high speed.

In such a stirring assembly machine, the processed material in a tank is scraped up inside by being pushed up by the lower stirring blade of a low speed rotation, and a pile of the processed material is formed in the front part of the stirring blade in the rotation direction.

Then, the formed pile is subjected to shear force while being pushed down by the upper stirring member of the high speed rotation, and stirred together with the binder introduced into the tank to repeat granulation and pulverization. It is supposed to be formed.

However, since the lower stirring blade has a larger partial area facing the bottom surface of the tank, the resistance increases during stirring of the processing material, the amount of the processing material adhering to the bottom surface of the tank increases, and power consumption is high. Gets bigger

Moreover, since the force which pushes a processed material is small from the problem of a stirring blade shape, it becomes difficult to stir a processed material uniformly over the whole, and cannot form a granular material of uniform particle size.

Agitated granulators for preventing the attachment of the treatment to the bottom or inner wall of a tank are disclosed in Special Publication No. 59-21649.

The stirring granulator is provided with a stirring blade on the bottom side of the tank and a grinding blade in a tank above the stirring blade. The stirring blade is rotatable in different directions by connecting the stirring blade and the grinding blade to different rotary shafts.

In such a stirring assembly machine, the processed material put into the tank is scraped up by the front end projection of the stirring blade while being pushed upward by the rotation of the stirring blade at low speed, and treated in the rotational direction front part of the stirring blade. A pile of water is formed.

The pile formed as described above is pulverized by applying a shearing force by the rotation of the pulverized blade at a high speed, and is stirred together with the binder introduced into the tank to form granules having a desired particle size by repeating granulation and pulverization. .

However, in the above-described agitating granulator, since the center of rotation, which is the agitator blade driving source, and both ends of the agitator blade are located almost in a straight line, the load becomes very large during rotation, and the workpiece is easily attached to the bottom side of the tank. At the same time, the force to push the treatment upwards is small.

Therefore, even if the pulverized blade is rotated at a high speed, the processed object cannot be stirred uniformly over the whole, so that it is not possible to form a particulate matter having a uniform particle size.

In addition, when the tank into which the processing material and the binder are put in a large size, disassembly and assembly of the tank takes time, and it takes a very long time to maintain and manage the stirring blade and to replace it.

Accordingly, an object of the present invention is to provide a stirring granulator capable of stirring with a small driving force and at the same time preventing the attachment of the treatment to the bottom and inner wall surfaces of the tank.

In addition, the present invention can stir with a small driving force, at the same time prevent the adhesion of the treatment to the bottom surface and the inner wall surface of the tank, and by uniformly stirring the treatment throughout the whole to obtain a uniform particle-like product It is to provide a stirring assembly that can be made.

In addition, the present invention can stir with a small driving force, while preventing the adhesion of the treatment to the bottom surface and the inner wall surface of the tank, and by stirring the treatment over the whole, to obtain a granular material having a uniform particle size. At the same time, an object of the present invention is to provide a stirring assembly that is easy to maintain and maintain even in a large tank.
