本発明は上下方向の回転軸のまわりに回転可能なふるい
面を有するふるい装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sieving device having a sieving surface that is rotatable around a vertical axis of rotation.
この種のふるい装置はオランダ特許用ｊ［１１７６０５
５７２に記載されている。そのふるい装置においては、
ふるい面は円錐外面の一部を形成し、十のｔｏ＋転軸に
最も近い部分が下方に位置し回転軸から蟻も遠いふるい
面部分が上方に位置する。操作に際しては、被ふるい物
質はふるい面に沿って外方へと移組し・細かい粒子はふ

れる。This type of sieving device is known from the Dutch patent J [117605
572. In the sieving device,
The sieve surface forms a part of the outer surface of the cone, and the part closest to the axis of rotation is located at the bottom, and the part of the sieve surface farthest from the axis of rotation is located at the top. In operation, the material to be sieved is moved outward along the sieve surface, with fine particles passing through the sieve surface and coarse particles being excluded from the periphery of the sieve.
この既知の構造においては、被ふるい物質の速用は物質
が回転軸から遠ざかるＫつれて増大し、ふるい鋤１の寸
法も回転軸からの距離の２乗で増大する。In this known construction, the velocity of the material to be screened increases as the material moves away from the axis of rotation, and the dimensions of the sieve plow 1 also increase with the square of the distance from the axis of rotation.
回転スピードか低い場合には、ふるい面の外周部分に向
かっての被ふるい物質の移動のスピードね回転軸の近辺
では比較的小さく、従って単位時ｒμｍ１り比較的少量
の物質しか処理できない。一方、ふるい面の回転スピー
ドを上げた場合には、回転軸から遠いふるい面の大部分
においては有効なふるいが不−ｊ能な様な速度で物質か
移動する。If the rotational speed is low, the speed of movement of the material to be screened towards the outer circumference of the sieve surface is relatively small in the vicinity of the rotational axis, and therefore only a relatively small amount of material per r.mu.m can be processed. On the other hand, when the rotational speed of the sieve surface is increased, the material moves at such a speed that effective sieving is impossible in most of the sieve surface far from the axis of rotation.
この既知のふるい装置の他の欠点は、粒子かふるい面の
孔に容易に固着し、遠心力又は重力の作用にもかかわら
ず孔中にしっかりと保持されるので決して離脱しないこ
とである。Another disadvantage of this known sieving device is that the particles easily stick to the pores of the sieve surface and are held firmly in the pores, despite the action of centrifugal or gravitational forces, so that they never dislodge.
本発明は既知のふるい装置の有する欠点のないふるい装
置を提供することを目的とする。The object of the invention is to provide a sieving device that does not have the disadvantages of known sieving devices.
本発明の１つＫよれば、上記の目的は、ふるい面の回転
軸近くの部分と外周近くの部分とがそれらの中間部分よ

達成される。この構成により、回転軸の近辺においては

近辺においては遠心力か重力のふるい面に平行な成分に
より弱められる。かぐして、このカーブふるい面構造に
よれば、ふるい面に沿っての物質粒子の移動の速度は最
適のふるい効果か得られる様な影響を受ける。According to one aspect of the present invention, the above object is achieved by providing a curve to the sieve surface so that the portion near the rotation axis and the portion near the outer periphery of the sieve surface are higher than the intermediate portion thereof. Ru. With this configuration, near the rotation axis, the centrifugal force acting on the material particles or the gravitational force acting on the particles is strengthened by the component parallel to the sieve surface, while near the outer periphery of the sieve surface, the centrifugal force or gravity acts on the sieve surface. weakened by parallel components. Accordingly, with this curved sieve surface structure, the speed of movement of material particles along the sieve surface is influenced such that an optimum sieving effect is obtained.
本発明の他の１つによれば、ふるい面は少くとも実質上
平行な２つの回転軸のまわりに回転可能である。これＫ

固着に基〈ふるいの目づまりか防止される。According to another aspect of the invention, the sieve surface is rotatable about at least two substantially parallel axes of rotation. This is K
As a result, the normal sieve surface rotation KWK is superimposed, so that the sieve surface performs a so-called small circular movement under the material to be sieved, which causes particles to stick to the pores of the sieve surface. Prevents clogging.
本発明の更に別の１つによれは、ふるい装置の回転軸を

い面の目づまシＦｉ肩効に防止される。According to a further aspect of the invention, means are provided for imparting a tilting movement to the sieve surface about an axis transverse to the axis of rotation of the sieve device. As a result, the sieve moves up and down, and at this time, the sieve surface height increases as it moves away from the axis of rotation.This method also prevents the sieve surface from becoming clogged.

遠心力を倫助する。During operation of the device of the invention, the material to be sieved is fed [123
is fed onto the sieve surface. By the motor 18,
The sieve surface rotates 9 around the axis of rotation of the shaft 12, and the material that impinges on the sieve surface is subjected to centrifugal force and moves outward along the sieve surface. The fine particles of material pass through the holes in the sieve surface and reach the channel 3, guided or unguided by the conical gray) 19. By means of the strip and the groove 20, this material is moved towards the opening in which the groove 4 is connected to the groove 3, so that the fine material is discharged through the groove 4 to the outside. Coarse particles of the material move outward along the sieve surface 22 and are discharged from the outer ruts of the sieve surface, and the charged material consisting of the lower outlet of the nounong 1 is initially Since it moves on the downwardly inclined portion of the sieve surface 22, the movement of this material is further accelerated by the action of the component of gravity parallel to the sieve surface. This component of gravity thus supports the centrifugal force that causes the outward displacement of matter.

くとも実質上一定となる様に形成するのか好ましい。After crossing the lowest part of the sieve surface, the material moving along the sieve surface moves upwards towards the outer green part of the sieve surface. In this upward movement, the component of gravity parallel to the sieve plane acts against the centrifugal force. Therefore, by properly forming the curve in the sieve direction, the most effective displacement of the material along the sieve surface is maintained, and in particular the speed at which the material particles move outward from the center of the sieve direction is maintained. It is preferable to form it so that it is at least substantially constant in the horizontal direction.

る。In a preferred embodiment of the invention, the sieve surface not only rotates around an axis of rotation formed about the center aK of the shaft 12, but also the shaft 6 with the shaft 12 is rotated by the electric motor 11. When the axes are arranged as shown in FIG. 2, the sieve surface swings in the direction of the water f, and the amplitude of the sieve surface is twice the distance between the center lines of the two axes. Preferably, the rotational speed of the shaft 6 exceeds the rotational speed 9 of the sieve surface of the turns of the shaft 12, so that the sieve surface undergoes a strong rocking movement, which movement prevents clogging of the holes in the sieve surface. .

つ・When the shafts are arranged as shown in FIGS. 3 and 4, the sieve surface tilts at four appropriate angles with respect to the center line of the shaft 6 around the tentative tilt axis Pj. From e·', it can be seen that the sieve surface moves up and down during operation, and the deflection of the sieve surface increases as K moves away from the rotation axis. This enhances the sieving effect and helps prevent clogging of the sieve surface.
