送風翼17は例えば遠心翼であつて、回転中心
から外側へと空気を押し出す。 The blower blades 17 are, for example, centrifugal blades, and push air outward from the center of rotation.
この空気は回転円板8の外周と造粒槽1の内周
との間隙18を通り、上昇気流として造粒槽1の
内周に沿つた流れとなる。 This air passes through the gap 18 between the outer periphery of the rotating disk 8 and the inner periphery of the granulation tank 1, and flows as an upward air flow along the inner periphery of the granulation tank 1.
主軸2の中心部には、外気を導入するための通
路19が形成され、軸端に開口する取入口20か
らの外気を、ボス部9の内側に開口する送気口2
1から回転円板8と底板16の間に導く。 A passage 19 for introducing outside air is formed in the center of the main shaft 2, and an air supply port 2 that opens inside the boss portion 9 receives outside air from an intake port 20 that opens at the end of the shaft.
1 to between the rotating disk 8 and the bottom plate 16.
なお、この外気導入通路19は上記底板16を
貫通して形成することも可能で、この場合はなる
べく回転中心に近づける。 Note that this outside air introduction passage 19 can also be formed to pass through the bottom plate 16, and in this case, it is placed as close to the center of rotation as possible.
主軸2とガイドパイプ5との間にはオイルシー
ル23が設けられ、軸受ハウジング3の内部の潤
滑油(グリース)が造粒槽1の内部へと漏洩しな
いように封止している。 An oil seal 23 is provided between the main shaft 2 and the guide pipe 5 to prevent lubricating oil (grease) inside the bearing housing 3 from leaking into the granulation tank 1 .
また、主軸2の外部への突出端には、プーリ2
4が取付けられ、図示しない駆動ベルトにより回
転円板8及び回転刃10を回転させる。 In addition, a pulley 2 is provided at the externally protruding end of the main shaft 2.
4 is attached, and a rotating disk 8 and a rotating blade 10 are rotated by a drive belt (not shown).
以上のように構成され、次にその作用について
説明する。 The device is configured as described above, and its operation will be explained next.
造粒槽1の内部に摩砕、造粒する所定の粉体
(原材料)を、上蓋14を取り外して規定量だけ
投入する。 A predetermined amount of powder (raw material) to be ground and granulated is poured into the granulation tank 1 by removing the upper lid 14.
主軸2を回転させて回転円板8とともに回転刃
10を一体に回わすと、投入粉体は回転円板8の
遠心力で回転外側に飛ばされ、さらに造粒槽1の
内周壁に沿つて上昇し、重力とバランスした位置
から落下するということの繰り返される流動槽を
形成する。 When the main shaft 2 is rotated and the rotary blade 10 is rotated together with the rotary disc 8, the charged powder is blown to the outside of the rotation by the centrifugal force of the rotary disc 8, and further along the inner circumferential wall of the granulation tank 1. It forms a fluidized tank in which it repeatedly rises and falls from a position balanced with gravity.
そして、この流動槽は上昇及び下降過程におい
て、水平面で回転する回転刃10によりスライス
される。 This fluidized tank is sliced by a rotary blade 10 rotating in a horizontal plane during the ascending and descending process.
これらの結果、粉体は適度な摩砕と粉砕を重
ね、とくに原材料によつては遠心力だけだと局部
的に圧密され、粒子が不揃いとなるが、回転刃1
0による切断にもとづき粒子が均一化するのであ
る。 As a result, the powder undergoes appropriate grinding and pulverization, and depending on the raw material, centrifugal force alone can cause local compaction and particles to become irregular, but the rotary blade 1
The particles become uniform based on the cutting by zero.
一方、回転円板8の回転に伴い、その下面の送
風翼17により回転円板8と造粒槽1との隙間1
8を通しての上昇気流が送られるため、この隙間
18からの粉体の落下を防ぐことができる。 On the other hand, as the rotating disk 8 rotates, a gap 1 between the rotating disk 8 and the granulation tank 1 is generated by the blower blades 17 on the lower surface of the rotating disk 8.
Since the rising air current is sent through the gap 8, it is possible to prevent the powder from falling through the gap 18.
なお、送風翼17の中心部には外気導入通路1
9を介して外気が吸い込まれ、これが上昇気流と
して造粒槽1の内周に沿つて吹き上げられるので
あるが、この風量はわずかなものでよく、上昇気
流による粉体の攬拌の必要性はない。 Note that an outside air introduction passage 1 is provided in the center of the blower blade 17.
9, outside air is sucked in and blown up along the inner circumference of the granulation tank 1 as an updraft, but the amount of air only needs to be small, and there is no need to stir the powder with the updraft. do not have.
なお、造粒槽1の内部に金属ボールを混ぜて攬
拌混合すると、ボールの衝突等により生じた金属
微粉を粉体の表面に付着させることができ、無機
粉体を一種の金属改質することが可能となるが、
この場合回転刃10は金属ボールの踊りを防ぎつ
つ摩減を促進させるのに効果がある。 In addition, when metal balls are mixed inside the granulation tank 1 and mixed by stirring, the metal fine powder generated by the collision of the balls, etc. can be attached to the surface of the powder, resulting in a kind of metal modification of the inorganic powder. It becomes possible, but
In this case, the rotary blade 10 is effective in preventing the metal balls from dancing and promoting wear.
以上のように本考案によれば、造粒槽の内部に
回転円板とその上方に回転刃を設けたため、効率
的な摩砕、粉砕作用にもとづき均一的粒子の造粒
が行える。 As described above, according to the present invention, since a rotating disk is provided inside the granulation tank and a rotating blade is provided above the rotating disk, uniform particles can be granulated based on efficient grinding and crushing actions.
また、回転円板と造粒槽の隙間からの上昇気流
により、粉体の落下を防いで造粒効率を高めるこ
とができ、しかもこの上昇気流を発生させる送風
翼を回転円板、回転刃とともに主軸により回転駆
動するので、これらの動力源は単一のものでよ
く、構造の簡略化がはかれる。 In addition, the upward airflow from the gap between the rotating disk and the granulation tank prevents the powder from falling and increases granulation efficiency, and the blower blades that generate this upward airflow are used together with the rotating disk and rotating blades. Since they are rotationally driven by the main shaft, a single power source is required for these, which simplifies the structure.
