本発明は、液体及び粉体又は粒体等の資料を連
続的に混合する混合機に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mixer that continuously mixes materials such as liquid and powder or granules.
（従来の技術）
液体と粉体等の混合資料を連続的に混合する装

−2507号、特公昭55−4455号等が既に開示されて
いる。(Prior art) Patent Publication No. 1986-22511 and Japanese Patent Publication No. 1973 are inventions of devices for continuously mixing mixed materials such as liquids and powders.
-2507, Japanese Patent Publication No. 55-4455, etc. have already been disclosed.
上記発明の混合装置は、何れも水平回転する主

拌板）の回転により投入した液体、粉体等の資料
を遠心力によつて円周方向に飛散させつつ該突片
と衝突させて剪断的に撹拌することをその主たる
構造としている。 In each of the above-mentioned mixing devices of the invention, protrusions are installed on the main plate (stirring plate) that rotates horizontally, and materials such as liquids and powders put in are transferred by centrifugal force as the main plate (stirring plate) rotates. Its main structure is to scatter it in the circumferential direction and cause it to collide with the protrusions to create shearing agitation.
（発明が解決しようとする問題点）
しかしながら、上記構造を有する混合装置等
は、何れも水平回転する主板（撹拌板）上での剪
断的撹拌のみである為、主板（撹拌板）の回転速
度を高めて撹拌時間を短縮させれば、外周部への
飛散速度が早くなつて瞬時に主板（撹拌板）を通
過してしまい十分な撹拌作用を受けられない。(Problems to be Solved by the Invention) However, since all of the mixing devices having the above structure perform shear stirring only on the main plate (stirring plate) that rotates horizontally, the rotational speed of the main plate (stirring plate) If the stirring time is shortened by increasing the stirring time, the scattering speed toward the outer periphery increases and instantaneously passes through the main plate (stirring plate), making it impossible to receive sufficient stirring action.
又主板（撹拌板）の回転を低速にすれば、外周
部へ飛散する速度が遅くなるに従つて突片による
剪断的撹拌の割合は大きくなるが撹拌効率は低下
する。更に又、上記主板（撹拌板）の回転速度を
上げながらも撹拌精度を高めるために、突片の数
を多く植設すれば、撹拌性能は向上するものの、
撹拌槽内で資料の付着が生じる等別個な問題を呈
することになる。 Furthermore, if the main plate (stirring plate) is rotated at a low speed, the rate of shear stirring by the protrusions increases as the speed of scattering toward the outer periphery decreases, but the stirring efficiency decreases. Furthermore, in order to increase the stirring accuracy while increasing the rotational speed of the main plate (stirring plate), if a large number of protrusions are installed, the stirring performance will improve;
Separate problems may arise, such as material adhesion within the stirring tank.

て十分な混合を行なうものである。 Therefore, in the primary mixing chamber, each mixed material is scattered by the centrifugal force caused by the high-speed rotation of the rotating mixer and mixed in a shearing manner, and then transported to the secondary mixing chamber. The mixture is allowed to remain for a required period of time to achieve sufficient mixing.

On the other hand, when powder or granules as other mixed materials are introduced from the supply pipe 14a, these powders or granules are also scattered in the peripheral direction due to the centrifugal force caused by the rotation of the upper rotating surface 21, and the liquid in this scattered state The powder or granules meet on the upper rotating surface 21. The liquid, powder, etc. collide with the protrusions 21a, 21b, and are mixed in a shearing manner. The mixed materials mixed in the primary mixing chamber R 1 are sequentially conveyed to the secondary mixing chamber R 2 according to the rotation of the rotary mixing body 2 .

により剪断的に混合されながら遠心力によつて回
転軸３から遠ざかる方向の力を受ける。 In the secondary mixing chamber R2 , as described above, the side rotating surface 22 is obliquely moved close to the rotating shaft 3, so that the mixed material transported is transferred to the protrusions 22a, 22b, . . .
While being mixed in a shearing manner, it is subjected to a force in a direction away from the rotating shaft 3 due to centrifugal force.

できる。 However, even if the mixed material receives a force that moves it away from the rotating shaft 3, the side wall 13 exists outside the side rotating surface 22, so as a result, the mixed material gradually rises on the side wall 13. In the so-called secondary mixing chamber R2 , the material rises according to the centrifugal force, and in the primary mixing chamber R1.
A new mixed material is transported from the source, and both mixed materials can obtain sufficient mixing time. Furthermore, if the scrapers 23, 23 are provided at a predetermined angle, a downward force will be applied to the mixed material by rotation, and the mixing in the secondary mixing chamber R2 can be adjusted.

ことになる。 Therefore, the discharge port 15 is opened to form the secondary mixing chamber R2.
By sequentially discharging the mixed materials from the supply section 14, the materials continuously supplied from the supply section 14 can be continuously taken out from the discharge port 15 as sufficiently mixed materials.
尚、上記説明では上部回転面２１と側部回転面
