2. Description of the Related Art Conventionally, as a device for agitating and mixing various powders and granules, the powder and granules are put into a fixed container, and a stirring blade provided in the container is horizontally rotated by a driving device to powder the powders. An apparatus for stirring and mixing granules has been used in a wide range of fields because it has advantages such as a simple apparatus structure and an easy environment for mixing such as vacuum, heating, and cooling.

However, in the agitating and mixing apparatus described above, when a large amount of powdery or granular material is agitated and mixed at once, or when viscous powdery or granular material is agitated and mixed by using a binder or the like. The centrifugal force due to the rotation of the stirring blade was not easily applied to the powder and granules, and the dispersibility of the powder and granules was particularly poor at the initial stage of stirring and mixing. In such a case, stirring and mixing for a long time was required to completely mix the powder and granules, so that poor productivity was a problem. The present invention has been made to solve the above problems, in particular improve the dispersibility of the granular material at the initial stage of stirring and mixing, even in a short time even a large amount of granular material or viscous granular material. It is an object of the present invention to provide a powder / granule stirring / mixing device capable of performing sufficient stirring / mixing.

[0004]

In order to achieve the above-mentioned object, in a powder and granular material stirring and mixing apparatus according to the present invention, a first drive rotation vertical shaft is vertically passed through the center of the bottom of a fixed container and horizontally rotatable. A gear box is fixedly mounted on the upper end of the first drive rotation vertical shaft, and a horizontal shaft horizontally projecting from the inside to the outside is vertically rotatably supported on one side of the gear box. At the same time, a plurality of rows of agitation blades are provided on the horizontal shaft at appropriate intervals, and the second drive rotation vertical shaft is vertically penetrated through the ceiling portion of the gear box and horizontally supported to support the shaft. , The second drive rotation vertical shaft and the horizontal shaft are connected to each other in the gear box via a gear so that the horizontal shaft can be vertically driven and rotated, and a bearing is fixed to the other side of the gear box via an arm. Then
A vertical shaft is axially supported by the bearing, and a plurality of stirring blades are provided in a plurality of rows at appropriate intervals on the vertical shaft, and the second drive rotation vertical shaft and the vertical shaft are connected via a pulley and a belt. ,
The feature is that the vertical axis can be rotated horizontally.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail with reference to FIGS. Reference numeral 1 denotes a cylindrical container fixed to a frame (not shown). A first drive rotation vertical shaft 2 (hereinafter referred to as the first vertical shaft 2) is vertically penetrated through the center of the bottom portion of the container 1 and is horizontally supported by a bearing 3 so as to be horizontally rotatable. A gear box 4 is fixed to the upper end of the first vertical shaft 2. On one side of the gear box 4, a horizontal shaft 5 horizontally protruding from the inside to the outside is rotatably supported by a bearing 6 so as to be vertically rotatable. A plurality of stirring blades 7 are planted in a plurality of rows on the horizontal shaft 5 at appropriate intervals. The horizontal shaft 5 has a gear 8 in the center of the shaft in the gear box 4. Also,
A second drive rotation vertical shaft 9 is provided on the ceiling of the gear box 4.
(Hereinafter referred to as the second vertical shaft 9) is vertically penetrated. The second vertical shaft 9 is rotatably supported by a bearing 10 fixed to the gear box 4 via a bearing 11 so as to be horizontally rotatable. In the gear box 4, a gear 12 provided at the base end of the second vertical shaft 9 and a gear 8 provided at the base end of the horizontal shaft 5 mesh with each other. An arm 13 is fixed to the other side of the bearing 10 (the side opposite to the projection of the horizontal shaft 5), and another bearing 14 is fixed to the tip of the arm 13. The bearing 1
A vertical shaft 16 is rotatably supported by the bearing 4 via a bearing 15 so as to face downward. A plurality of stirring blades 17 are planted in a plurality of rows on the vertical shaft 16 at appropriate intervals. The second vertical shaft 9 and the vertical shaft 16 have pulleys 18 and 19, respectively, and are connected by a belt 20. The first vertical shaft 2 and the second vertical shaft 9 have gears 21 and 22 respectively at the tips of the ones projecting to the outside of the container 1, and the gears 21 and 22 are driven by the drive devices 23 and 24, respectively. It meshes with rotating gears 25 and 26. In addition, 2
Scrapers 7 and 28 are attached to the gear box 4. In the above embodiment, the arm 13 is attached to the bearing 10.
However, the same effect can be obtained by mounting it on a member that rotates integrally with the gear box 4.

A process of actually stirring and mixing the powdery particles by using the powdery particle stirring and mixing apparatus will be described. Container 1
After being put into the inside, the gear 25 is driven by the driving device 23.
Also, the first vertical shaft 2 is rotated via the gear 21 to horizontally rotate the gear box 4, and the horizontal revolution of the horizontal shaft 5 and the vertical shaft 16 is performed. At the same time, the drive device 24 drives the second vertical shaft 9 to rotate via the gear 26 and the gear 22, and the gear 12 rotates in the gear box 4 to rotate the gear 8 meshing therewith. In this way, the horizontal shaft 5 connected to the gear 8 and the stirring blade 7 rotate in the vertical direction. Further, the rotation of the second vertical shaft 9 causes the pulley 18 to rotate, and the belt 20
The pulley 19 is rotated via. Thereby, the horizontal rotation of the vertical shaft 16 and the stirring blade 17 is performed. As described above, in the powder / granule stirring / mixing device according to the embodiment of the present invention, the stirring blade 7 simultaneously rotates in the vertical direction while revolving horizontally, and applies a centrifugal force in two directions to the powder / granular material to add stirring. The blades 17 revolve horizontally in synchronization with the stirring blades 7 while simultaneously rotating in the horizontal direction. As a result, the dispersibility of the powder and granules is improved from the initial stage of mixing, and efficient stirring and mixing can be performed. The scrapers 27 and 28 are the stirring blades 7 and 1.
The powder and granules that have moved outside the rotation range of 7 are scraped into the rotation range of the stirring blades 7 and 17, and the stirring and mixing of the powder and granules are performed more effectively.

[0007]

As is clear from the above description, the powder and granular material stirring and mixing apparatus according to the present invention performs vertical rotation at the same time while rotating the stirring blades horizontally in the container, and the powder and granular materials are vertically and horizontally rotated. In addition to imparting centrifugal force in two directions, by rotating the other stirring blade horizontally while simultaneously rotating in the horizontal direction, the particles can be efficiently stirred and mixed, especially when the particles are dispersed at the initial stage of mixing. Can be better. Therefore, even a large amount of powdery particles or viscous powdery particles can be sufficiently stirred and mixed in a short time, which is useful for improving productivity.
