本発明は、連続式遠心分離機におけるスクリューに関し
、スクリュー軸に大小二つのスクリューを具備せしめて
沈降物と浮遊物とを個別に処理せんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screw in a continuous centrifugal separator, and the screw shaft is equipped with two large and small screws to treat sediment and suspended matter separately.

Ｓの末端にフローシャイベ４を取りつけることは良く知
られた方法である。Conventionally, when centrifuging the material, it separates into three phases: suspended matter (floatable solids) at the top, then liquid, and then sediment (solids) at the bottom. It is a well-known method to attach a flowshibe 4 to the end of the screw S, as shown in FIG. 1, for the purpose of discharging the liquid together with the liquid as a loss or recovering floating solids.

側へ排出させる作用が完全でなく、給液開始後、ある時
間経過すれば、浮上性固形物が、スクリューＳにまつわ
りついてしまい、分離操作が悪化する現象が起る。However, depending on the properties of the floating solids, a flowshibe 4 may be installed to prevent the floating solids from flowing out to the drain port 5 side, and a screw S may be used to remove the floating solids from the cake discharge port 6.
If the effect of discharging to the side is not complete and a certain period of time has passed after the start of liquid supply, the floating solids will cling to the screw S, causing a phenomenon that the separation operation will deteriorate.
特に、胚芽を含むような糖蜜に於ては、浮上性固形物で
ある胚芽をロスとして液体と一緒に排液口５側へ排出さ
せようとしても、フローシャイベ４を取りつげた時と同
じような現象が生ずる。In particular, in the case of molasses that contains germ, even if you try to drain the germ, which is a buoyant solid, to the drain port 5 side along with the liquid as a loss, it will not work like when you install Flosheibe 4. A phenomenon occurs.
以下本発明を実施例に基づいて説明する。The present invention will be explained below based on examples.
図に於てＢは連続式遠心分離機の本体、１はこの本体Ｂ
内に設けたスクリュー軸で、該スクリュー軸１は原動機
により所要回転数にて駆動されるようになしている。In the figure, B is the main body of the continuous centrifuge, and 1 is the main body B.
A screw shaft 1 is provided inside the screw shaft 1, and the screw shaft 1 is driven by a prime mover at a required rotation speed.
又このスクリュー軸１の外周には本体Ｂの内周壁面とス

収したる羽根を設ける。Further, on the outer periphery of this screw shaft 1, a material is wound spirally over its entire length so that the processed material is separated and conveyed between the inner peripheral wall surface of the main body B and the outer peripheral surface of the screw shaft by centrifugal action. Provide a feather.
この羽根は第２図・第３図に詳記する如く、大径の羽根

り抜き部２ａ内を小径羽根３が接触しないように、交叉
するようにして設ける。As detailed in Figures 2 and 3, this blade consists of a large-diameter blade 2 and a small-diameter blade. It is fixed to the screw shaft 1 via the provided stay, and the large diameter blade (
The small-diameter blades 3 are provided so as to cross inside the hollowed out part 2a so as not to come into contact with each other.
従ってこの小径羽根３の径は大径羽根の（り抜き部の内
径より小となすものである。Therefore, the diameter of the small-diameter blade 3 is smaller than the inner diameter of the hollowed-out portion of the large-diameter blade.

出側に排出する機能をもち、又第３図に示すものは小径
羽根と大径羽根とを互に逆方向に巻収したもので、浮上
性固形物を排液口側に排出させる機能をもつ。The large-diameter blade 2 carries out solid matter that has settled on the outer periphery of the centrifuge body, and the small-diameter blade 2 carries out objects that are floating near the screw shaft surface when floating solids are present, as shown in Figure 2. The one shown in Figure 3 has a large diameter blade and a small diameter blade wound in the same direction, and has the function of discharging floating solids (floating matter) to the cake discharge side. The diameter blades are wound in opposite directions, and have the function of discharging floating solids to the drain port side.
尚犬小径両羽根は同ピツチとしたがピッチを夫夫具にす
ることもある。Both blades of the dog path are of the same pitch, but the pitch may also be changed.
而して本発明による時はスクリュー軸に大小異径の羽根

うにして設けているため浮遊物と沈澱物とを夫々独立し

離効率が向上する利点がある。According to the present invention, the screw shaft is provided with blades of different sizes and diameters, and the large diameter blade is provided with a hollowed out portion so that the small diameter blade intersects with the small diameter blade, so that floating matter and sediment can be carried out independently. This has the advantage of improving separation efficiency, regardless of the properties of the processed material.
