【発明の詳細な説明】
本発明は液中に浮遊する微粒子をこの液中に粘着剤を加
えてこの液に旋回を与えることにより凝集粒子化する装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for agglomerating fine particles suspended in a liquid by adding an adhesive to the liquid and swirling the liquid.
従来この種装置には第1図aにその断面で示すようなも
のがある。Conventionally, there is a device of this type as shown in cross section in FIG. 1a.
これは一つまたはいくつかの翼車1を軸2に装置しこれ
を円筒型容器3内で回転させるものである。This is a system in which one or several impellers 1 are mounted on a shaft 2 and rotated within a cylindrical container 3.
粘結剤を加えられた微粒子を含む液体は造粒機人口4よ
り吸い込まれ翼車にて旋回されて造粒作用を受け、適当
な粒径に造粒されて吐出口5より送り出される。A liquid containing fine particles to which a binder has been added is sucked into the granulator 4, rotated by a blade wheel, subjected to a granulation action, granulated to an appropriate particle size, and sent out from a discharge port 5.
第1図すは翼車1の正面図を示す。FIG. 1 shows a front view of the impeller 1.
しかしこの形状では処理量あたりの所要動力が大きい欠
点があり、その主たる原因としては次の2つがある。However, this shape has the disadvantage that the required power per processing amount is large, and there are two main reasons for this.
(1)翼車径の小さい部分では造粒はおこらず単に液が
攪拌されているだけで無用なエネルギーの消散となって
いる。(1) In the part where the impeller diameter is small, granulation does not occur and the liquid is simply stirred, resulting in unnecessary energy dissipation.
(2)2段目以降の翼車は有効に造粒に寄与せず攪拌の
エネルギーだけを消費している。(2) The impellers in the second and subsequent stages do not effectively contribute to granulation and only consume energy for stirring.
本発明は以上の欠点を補い、より高効率で簡単な構造の
装置を提供するものである。The present invention compensates for the above-mentioned drawbacks and provides a device with higher efficiency and simpler structure.
また更に本発明は従来の造粒機には見られない製品粒径
を制御する機構も含んだものである。Furthermore, the present invention also includes a mechanism for controlling product particle size, which is not found in conventional granulators.
本発明は吸込部、ポンプ部、吐出路からなる遠心ポンプ
のポンプ部と吐出路の間にポンプ部のインペラに結合さ
れた回転円筒と、これと同心の円筒ケーシングからなる
造粒部分を設けたもので、これを第2図にその軸を通る
断面で示す。The present invention provides a centrifugal pump consisting of a suction part, a pump part, and a discharge passage, and between the pump part and the discharge passage, a rotating cylinder connected to an impeller of the pump part and a granulating part made of a cylindrical casing concentric therewith are provided. This is shown in Fig. 2 as a cross section passing through the axis.
9は遠心ポンプの吸込部、6は軸、7はインペラ、7a
はインペラ主板、7bはインペラ側板、8はケーシング
で、以上でポンプ部は構成される。9 is the suction part of the centrifugal pump, 6 is the shaft, 7 is the impeller, 7a
7b is the impeller main plate, 7b is the impeller side plate, and 8 is the casing, which constitute the pump section.
12は吐出路である。12 is a discharge path.
造粒部分はポンプ部のインペラ主板7aにこれと同径同
心の円筒10がインペラ翼と反対の側に取付けられてい
る。In the granulation part, a cylinder 10 having the same diameter and concentricity is attached to the impeller main plate 7a of the pump part on the side opposite to the impeller blades.
尚、円筒10のインペラ主板7aと反対側の終端は軸6
に取付けた吐出側円板10aに接続している。The end of the cylinder 10 opposite to the impeller main plate 7a is connected to the shaft 6.
It is connected to the discharge side disk 10a attached to the discharge side disk 10a.
この円筒10を取部く部分はこれと同心の円筒ケーシン
グ8aがインペラのケーシング8を吐出路9に取付けら
れている。A cylindrical casing 8a concentric with the cylinder 10 is attached to the impeller casing 8 in the discharge passage 9.
このようにして回転円筒10とケーシング8aとの間に
液の軸方向の通路でもある造粒室11が形成される。In this way, a granulation chamber 11, which is also an axial passage for liquid, is formed between the rotating cylinder 10 and the casing 8a.
この装置に微粒子の浮遊する液に粘結剤として例えば微
粒子が石炭のときには重油を加えてこの装置のポンプ作
用により通じれば、混合液は造粒室11内で旋回し、微
粒子は造粒室11の内壁に押しつげられ乍ら転勤してそ
の間に核のまわりへの凝集となり造粒作用が行はわれる
。When the liquid in which the fine particles are suspended is added with heavy oil as a binder, for example, when the fine particles are coal, and the liquid is passed through the pumping action of this apparatus, the mixed liquid swirls in the granulation chamber 11, and the fine particles are transferred to the granulation chamber 11. While being pressed against the inner wall of the nucleus, it is transferred, and during that time it aggregates around the nucleus and a granulation action takes place.
こ〜で液にインペラにより与えられた旋回成分はケーシ
ング壁面との摩擦により失われるがこれは回転円筒10
により補充される。At this point, the swirling component given to the liquid by the impeller is lost due to friction with the casing wall, but this is caused by the rotation of the rotating cylinder 10.
Replenished by
それでも、なお旋回成分が不足する場合には第3図aの
ように回転円筒10上に翼13を取付け、これにより旋
回成分を補えばよい。However, if the swirling component is still insufficient, the wing 13 may be attached to the rotating cylinder 10 as shown in FIG. 3a, thereby supplementing the swirling component.
第3図すは翼13を第3図aのAA力方向示したもので
ある。FIG. 3 shows the blade 13 in the AA force direction of FIG. 3a.
第4図aのように活粒室11の終端の回転円筒10上に
分級板14を取付げれば造粒された粒子の粒径選別を行
うこともできる。If a classification plate 14 is attached to the rotary cylinder 10 at the end of the active particle chamber 11 as shown in FIG. 4a, the particle size of the granulated particles can be sorted.
第4図すは分級板14の形状を同a図のBB矢視方向で
示し、それは下記のように粒子をはね返しうるものであ
ればよい。FIG. 4 shows the shape of the classification plate 14 in the direction of arrow BB in FIG.
造粒室終端部では粒径の大きな粒子は遠心力により外径
側に寄っているため分級板14とケーシング内壁との隙
間を通過する。At the end of the granulation chamber, particles with larger diameters are moved toward the outer diameter side due to centrifugal force, and therefore pass through the gap between the classification plate 14 and the inner wall of the casing.
一方粒径が小さいものは内径側を通るため分級板14に
衝突し造粒室11に戻され、再び造粒作用を受けること
になる。On the other hand, particles with a small diameter pass through the inner diameter side, collide with the classification plate 14, and are returned to the granulation chamber 11, where they are subjected to the granulation action again.
つまり、この分級板14は粒子径の選別を行うとともに
造粒装置内の粒子の滞留時間を高める働きをしている。In other words, the classification plate 14 functions to sort the particle size and to increase the residence time of the particles in the granulator.
造粒された粒子の分級作用は第5図のような構造でも行
なわせることができる。The classification action of granulated particles can also be performed with a structure as shown in FIG.
これは吐出路15.16の2個の円筒形の造粒室11の
軸方向に重ねて並列においたものである。This is the arrangement of the two cylindrical granulation chambers 11 of the discharge passages 15, 16 which are arranged in parallel and stacked in the axial direction.
この2つの吐出路15,16の境17は造粒室11の終
端に舌状をなしてそこで粒子に対する分級作用を行う。A boundary 17 between these two discharge passages 15 and 16 forms a tongue at the end of the granulation chamber 11, and there performs a classification action on the particles.
すなわち径の大きい粒子は液の旋回半径の大きい側に集
る故境17より外側の吐出路15に流れ、残る小径粒子
は内側の吐出路16に流れる。That is, particles with a large diameter flow into the discharge passage 15 on the outside of the boundary 17 where the liquid gathers on the side with a large turning radius, and the remaining small-diameter particles flow into the discharge passage 16 on the inside.
