【考案の詳細な説明】
本考案は、懸濁物質を含む懸濁液から液中の懸濁物質を
粒状固形物に造粒分離せしめ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 granulating and separating suspended substances in a liquid into granular solids from a suspension containing suspended substances.
これまで、懸濁液中の懸濁物質を取り扱いの容易なペレ
ット状固形物とするため数多くの装置が考案され実用に
供されてきたが、実用の規模が拡大されるにつれ従来に
はみられなかったような問題点もでてきた。Until now, a number of devices have been devised and put into practical use in order to convert suspended solids in suspension into pellet-like solids that are easy to handle, but as the scale of practical use has expanded, Problems that didn't exist have also appeared.
即ち、ペレット生成の条件として槽内固形物濃度が重要
な役目を果たしており、３ＯＮ／Ｖ以下では生成困難で
’１０９／１以上が理想的とされてきた。That is, the concentration of solids in the tank plays an important role as a condition for pellet production, and it has been said that it is difficult to produce pellets below 3 ON/V, and that above '109/1 is ideal.
しかしながら、産業上発生する懸濁液の中には固形物濃
度が３０９／ｌ以下のものが数多くある。However, many industrially generated suspensions have a solids concentration of 309/l or less.
固形物濃度が低くても固形物の真比重が大きい場合には
ペレットの比重も大きくなり結果的に槽内で濃縮される
ため問題ないが、固形物濃度が低い懸濁液は固形物の真
比重も小さいのが通例である。Even if the solids concentration is low, if the true specific gravity of the solids is high, the specific gravity of the pellets will also be large and the pellets will be concentrated in the tank, so there is no problem. The specific gravity is also usually small.
そのような場合、槽内で３０ｆ／１以上の濃度を保つこ
とはかなり難しく、良好なペレットも生皮しないことが
多い。In such cases, it is quite difficult to maintain a concentration of 30 f/1 or higher in the tank, and even good pellets often do not turn raw.
本考案は、懸濁固形物濃度が１０〜３０９／ｌの比較的
低濃度の懸濁液に対しても安定した造粒が得られる装置
を提供しようとするものである。The present invention aims to provide an apparatus that can provide stable granulation even for suspensions with relatively low suspended solids concentrations of 10 to 309/l.
すなわち本考案の装置は、懸濁固形物濃度を増大するた
めの濃縮機構を付設した造粒装置であり、懸濁物質を含
む懸濁液を流入せしめて懸濁物質の造粒分離を行なう槽
体において、該槽体内に前記懸濁液及び造粒剤を供給し
得るように構威し、前記槽体内下方部に旋回流を生せし
めるように回転翼を設けると共に、該回転翼より上方部
かつ液面下に位置するように案内中空筒を設け、該案内
中空筒の内側かつ上端が液面上に位置するように内部中
空筒を配備し、さらに、該内部中空筒内側から前記槽体
内の液及び造粒剤が流出するように流出管を設けたこと
を特徴とするものである。In other words, the device of the present invention is a granulation device equipped with a concentration mechanism for increasing the concentration of suspended solids, and includes a tank into which a suspension containing suspended solids is introduced and the suspended solids are granulated and separated. The body is configured to be able to supply the suspension and granulation agent into the tank body, and is provided with rotary blades so as to generate a swirling flow in the lower part of the tank body, and has a rotor blade provided in the lower part of the tank body, and an upper part of the rotor blade. A guide hollow cylinder is provided so as to be located below the liquid level, an internal hollow cylinder is provided so that the inside and upper end of the guide hollow cylinder is located above the liquid level, and further, a guide hollow cylinder is provided so that the inside and upper end of the guide hollow cylinder is located above the liquid level. The invention is characterized in that an outflow pipe is provided so that the liquid and the granulating agent can flow out.
このように、本考案は従来の造粒装置にはなかった機能
を付加し、槽内に攪拌作用を受けない濃縮ゾーンを設け
て沈殿濃縮を行なわしめ、３０ｆ／ｌ以下の低濃度懸濁
液に対しても常に槽内で３０９／１以上の濃度が保たれ
るようにしたものであり、ひいては造粒性能の向上にも
つながるものである。In this way, the present invention adds functions not found in conventional granulation equipment, and allows precipitation and concentration to be carried out by providing a concentration zone in the tank that is not affected by agitation, thereby producing a suspension with a low concentration of 30 f/l or less. However, the concentration is always maintained at 309/1 or higher in the tank, which in turn leads to improved granulation performance.

ように配備する。Further, a rotary blade 5 is provided at the lower part of the tank body 1 to generate a swirling flow in the liquid in the tank, and a guide hollow cylinder 6 is provided above the rotor blade 5, the upper end of which is slightly below the liquid level. Deploy it so that it is located at
前記回転翼５の形状としては槽内液に旋回流を与えるよ
うなものであれば任意のものでよく、例えばパドル状翼
などを用い、その段数も適宜に決定される。The shape of the rotary blade 5 may be any shape as long as it imparts a swirling flow to the liquid in the tank. For example, a paddle-shaped blade or the like is used, and the number of stages thereof is determined as appropriate.
案内中空筒６は槽体に数似する円筒又はこれに近い筒状
にし、リブ（図示せず）で回転軸８に支持させるか槽上
方から吊り下げ又は槽内壁に固定支持し、その外径は回
転翼５の長さあるいはその近辺とするのが合理的であり
、回転又は固定的な案内筒とすることが任意に選べる。The guide hollow cylinder 6 is shaped like a cylinder or similar to the tank body, and is supported on the rotating shaft 8 with ribs (not shown), suspended from above the tank, or fixedly supported on the tank inner wall, and its outer diameter It is reasonable to make the length of the rotary blade 5 or its vicinity, and it is possible to arbitrarily select a rotating or fixed guide cylinder.
なお、この案内中空筒６は一つ設けられているが必要に
応じ同心円状に２重、３重と間隔をあけて配備すること
もでき、この場合、高低の段差をつけて設けることもで
きる。Although one guide hollow cylinder 6 is provided, if necessary, it can be arranged concentrically in two or three layers at intervals, and in this case, it can also be provided with height differences. .
さらに、案内中空筒６の内側には回転翼５より上方で、
その上端が液面上に出るように内部中空筒７を設け、内
部中空筒７の上方には流出管４が開口連結しである。Furthermore, inside the guide hollow cylinder 6, above the rotor blade 5,
An internal hollow cylinder 7 is provided so that its upper end protrudes above the liquid level, and an outflow pipe 4 is open and connected above the internal hollow cylinder 7.
内部中空筒７の外径は、案内中空筒６より小さく、かつ
内部中空筒７での上昇流速がペレットの沈降速度を越え
ないような断面積をもつ外径以上とすることが必要であ
り、通常その外径は案内中空筒６の外径の４０〜６０％
とすることが好ましい。The outer diameter of the inner hollow tube 7 must be smaller than the guide hollow tube 6 and larger than the outer diameter with a cross-sectional area such that the upward flow velocity in the inner hollow tube 7 does not exceed the sedimentation speed of the pellets. Usually its outer diameter is 40 to 60% of the outer diameter of the guide hollow cylinder 6.
It is preferable that
なお、図示例では内部中空筒７と案内中空筒６はいずれ
も円筒体であり、同心状に配設されている。In the illustrated example, the internal hollow cylinder 7 and the guide hollow cylinder 6 are both cylindrical bodies, and are arranged concentrically.
図中８は回転翼５を支持する回転軸、９は駆動装置、１
０は支持枠体又は蓋体である。In the figure, 8 is a rotating shaft that supports the rotor blade 5, 9 is a drive device, 1
0 is a support frame or a lid.
しかして、懸濁液を供給管２から槽１内下方に供給する
と同時に造粒剤の適当量を注入管３から注入すると、回
転翼５による押出流及び案内中空筒６による循環流の中
で、次第にペレットが形成される。Therefore, when the suspension is supplied from the supply pipe 2 to the lower part of the tank 1 and at the same time an appropriate amount of granulation agent is injected from the injection pipe 3, the extrusion flow by the rotary blades 5 and the circulation flow by the guiding hollow cylinder 6 occur. , a pellet is gradually formed.
しかし槽内濃度が低い場合は、内部中空筒７を通過する
とき、上昇流速よりもペレットの沈降速度がまさるため
、ペレットは槽下方へと沈降し、分離液だけが流出管４
を通って排出される。However, when the concentration in the tank is low, the sedimentation speed of the pellets exceeds the upward flow rate when passing through the internal hollow cylinder 7, so the pellets settle to the bottom of the tank, and only the separated liquid flows into the outflow pipe 4.
is discharged through the
かかる期間を経過すると次第に槽内固形物濃度が高まり
、結局ペレット容積が増大するため、ペレットは下から
押し出されるようなかたちで流出管４から排出され、定
常状態に到達する。After this period has elapsed, the concentration of solids in the tank gradually increases, and the pellet volume eventually increases, so that the pellets are discharged from the outflow pipe 4 as if being pushed out from below, and a steady state is reached.
定常状態に達した以後は流入量に等しいだけの固形物と
液体とが連続的に排出される。After reaching a steady state, solids and liquid are continuously discharged in an amount equal to the inflow amount.
ペレット密度は槽内固形物濃度とともに徐々に増大し、
定常状態に達した以後は一定値をとる。The pellet density gradually increases with the solids concentration in the tank,
After reaching a steady state, it takes a constant value.
このように本考案は、造粒槽内に濃縮ゾーン（内部中空
