Description

本発明は、円筒篩の内側に投入された処理対象物に圧力を加えて当該処理対象物を篩い分ける篩処理装置に関する。   The present invention relates to a sieving apparatus for applying a pressure to a processing object put inside a cylindrical sieve and sieving the processing object.

円筒体の筒壁を貫通して篩目となる多数の貫通孔により形成された篩部と、円筒体の一端開口側に設けられた処理対象物の投入口と、円筒体の他端開口側に設けられた処理対象物の排出口とを備えた円筒篩と、円筒篩の内側に設けられて円筒篩の内側の処理対象物に圧力を付与する圧力付与手段とを備え、圧力付与手段は、円筒篩の中心線に沿って延長するように設けられたロータと、ロータから突出する押圧部としての羽根とを備え、円筒篩とロータとが回転することによって処理対象物が羽根により篩部に押し付けられて篩い分けされるように構成された本出願人による発明の篩処理装置が知られている（特許文献１参照）。   A sieve portion formed by a large number of through-holes that pass through the cylindrical wall of the cylindrical body and become a sieve, an inlet for a processing object provided on one end opening side of the cylindrical body, and the other end opening side of the cylindrical body And a pressure applying means that is provided inside the cylindrical sieve and applies pressure to the processing object inside the cylindrical sieve. A rotor provided so as to extend along the center line of the cylindrical sieve, and a blade as a pressing portion protruding from the rotor, and the object to be processed is sieved by the blade as the cylindrical sieve and the rotor rotate.

特開２０１４−５０７９８号公報JP 2014-50798 A

特許文献１の篩処理装置は、円筒篩の回転中心線とロータの回転中心線とが平行となるように構成されている。
しかしながら、円筒篩の投入口を介して円筒篩の内側に投入された処理対象物は円筒篩の篩部の篩目から落下するので、円筒篩の内側に投入された処理対象物の量は、円筒篩の投入口側から排出口側に向けて移動するのに従って少なくなる。このため、円筒篩の排出口側に近付くほど、ロータの羽根が処理対象物を円筒篩の篩部に押し付ける力が弱くなるので、当該羽根が空回りしやすくなって、ロータの羽根が処理対象物を円筒篩の篩部に押し付けることによる擦り付け動作が行われなくなり、処理対象物を効率的に篩分けることができなくなる。
本発明は、処理対象物を効率的に篩分けることができる篩処理装置を提供する。The sieving apparatus of Patent Document 1 is configured such that the rotation center line of the cylindrical sieve and the rotation center line of the rotor are parallel to each other.
However, since the processing object thrown into the inside of the cylindrical sieve through the inlet of the cylindrical sieve falls from the mesh of the sieve portion of the cylindrical sieve, the amount of the processing object put into the inside of the cylindrical sieve is It decreases as it moves from the inlet side to the outlet side of the cylindrical sieve. For this reason, the closer to the discharge port side of the cylindrical sieve, the weaker the force of the rotor blades pressing the object to be processed against the sieve part of the cylindrical sieve, so that the blades are more likely to idle, and the rotor blades become the object to be processed. The rubbing operation by pressing the squeezed on the sieve portion of the cylindrical sieve is not performed, and the object to be treated cannot be efficiently sieved.
The present invention provides a sieving apparatus capable of efficiently sieving a processing object.

本発明に係る篩処理装置は、円筒体の筒壁を貫通して篩目となる多数の貫通孔により形成された篩部と、円筒体の一端開口側に設けられた処理対象物の投入口と、円筒体の他端開口側に設けられた処理対象物の排出口とを備えた円筒篩と、円筒篩の内側に設けられて円筒篩の内側の処理対象物に圧力を付与する圧力付与手段とを備え、圧力付与手段は、円筒篩の中心線に沿って延長するように設けられたロータと、ロータから突出する押圧部とを備え、円筒篩とロータとが回転することによって処理対象物が押圧部により篩部に押し付けられて篩い分けされるように構成された篩処理装置であって、円筒篩の回転中心線及びロータの回転中心線が、円筒篩の投入口側から排出口側に向けて下るように傾斜するとともに、水平面に対するロータの回転中心線の傾斜角度が水平面に対する円筒篩の回転中心線の傾斜角度よりも大きいことを特徴とするので、排出口側に近付くほどロータの押圧部（羽根）が処理対象物を円筒篩の篩部に押し付ける力が弱くなってしまうことを抑制でき、処理対象物が少なくなる円筒篩の排出口側において、押圧部が処理対象物を篩部の篩目に擦りつける動作を確実に行えるようになり、処理対象物を効率的に篩分けできるようになる。
また、円筒篩の排出口側において、ロータの回転中心線は、円筒篩の回転中心線を通過する垂直線の位置よりも左側又は右側にずれて位置されていることを特徴とするので、押圧部が処理対象物を篩部の篩目に擦りつける動作を確実に行えるようになり、処理対象物を効率的に篩分けできるようになる。
また、ロータは、円筒篩の排出口側において、ヒンジ機構を介して、円筒篩の内面から離れる方向及び円筒篩の内面に近付く方向に移動可能に設置されたことを特徴とするので、円筒篩の排出口側で円筒篩と押圧部との間に大きな石等が挟まってロータが回転しなくなる前にロータが円筒篩の内面から離れる方向に逃げるため、ロータが回転しなくなるような事態を防止でき、ロータに大きな負荷が加わることを防止できるようになり、ロータの破損や回転駆動源の故障等を防止できるようになる。
押圧部は、ロータからの突出量が、円筒篩の投入口側では短く、かつ、円筒篩の排出口側では長いことを特徴とするので、処理対象物の投入量を多くできるとともに、処理対象物の量が少なくなってくる排出口側において、押圧部が処理対象物を篩部の篩目に擦りつける動作を確実に行えるようになり、処理対象物を効率的に篩分けできるようになる。The sieving apparatus according to the present invention includes a sieving portion formed by a large number of through-holes that pass through the cylindrical wall of the cylindrical body, and an inlet for a processing object provided on one end opening side of the cylindrical body And a cylindrical sieve having a processing object discharge port provided on the other end opening side of the cylindrical body, and a pressure application that is provided inside the cylindrical sieve and applies pressure to the processing object inside the cylindrical sieve. The pressure applying means includes a rotor provided so as to extend along a center line of the cylindrical sieve, and a pressing portion protruding from the rotor, and the cylindrical sieve and the rotor rotate to be processed. A sieving apparatus configured such that an object is pressed against a sieving part by a pressing part and sieved, and the rotation center line of the cylindrical sieve and the rotation center line of the rotor are discharged from the inlet side of the cylindrical sieve to the discharge port. And the rotor against the horizontal plane Since the inclination angle of the rotation center line is larger than the inclination angle of the rotation center line of the cylindrical sieve with respect to the horizontal plane, the pressing portion (blade) of the rotor moves the object to be treated to the cylindrical sieve sieve as it approaches the discharge port side. It is possible to suppress the pressing force to the part from weakening, and on the discharge side of the cylindrical sieve where the object to be processed is reduced, the pressing part can reliably perform the operation of rubbing the object to be processed on the sieve part of the sieve part. Thus, the object to be treated can be efficiently screened.
Further, on the discharge opening side of the cylindrical sieve, the rotation center line of the rotor is located on the left side or the right side of the position of the vertical line passing through the rotation center line of the cylindrical sieve. The part can reliably perform the operation of rubbing the processing object on the sieve of the sieving part, and the processing object can be efficiently screened.
In addition, the rotor is installed on the discharge port side of the cylindrical sieve so as to be movable in a direction away from the inner surface of the cylindrical sieve and a direction approaching the inner surface of the cylindrical sieve via a hinge mechanism. Since the rotor escapes away from the inner surface of the cylindrical sieve before a large stone or the like is caught between the cylindrical sieve and the pressing part on the discharge port side of the cylinder and the rotor stops rotating, the situation where the rotor does not rotate is prevented. Thus, it is possible to prevent a large load from being applied to the rotor, and it is possible to prevent damage to the rotor, failure of the rotational drive source, and the like.
The pressing part is characterized in that the amount of protrusion from the rotor is short on the inlet side of the cylindrical sieve and long on the outlet side of the cylindrical sieve. On the discharge port side where the amount of objects decreases, the pressing part can reliably perform the operation of rubbing the object to be processed on the sieve part of the sieve part, and the object to be processed can be efficiently screened. .

It is a means installed in the installation part 10 such as the ground or floor via the drive support mechanism 6 and the pressure applying means rotation drive support mechanism 7, and is formed by, for example, an inclined surface parallel to the rotation center line 4C of the cylindrical sieve 4. It is comprised by the installation stand provided with the installation surface 30.
For example, the inclination angle θ1 of the rotation center line 51C of the rotor 51 with respect to the horizontal plane H is set to 5 °, and the inclination angle θ2 of the rotation center line 4C of the cylindrical sieve 4 with respect to the horizontal plane H is set to 3 °.
In other words, the rotation center line 4C of the cylindrical screen 4 and the rotation center line 51C of the rotor 51 are inclined so that the position on the discharge port 44 side is lower than the input port 43 side of the cylindrical screen 4. The inclination angle θ1 of the rotation center line 51C of the rotor 51 is steeper than the inclination angle θ2 of the rotation center line 4C of the cylindrical sieve 4.
That is, as shown in FIG. 1, in the lowermost portion X of the rotating cylindrical sieve 4, the interval W between the blades 52 of the rotor 51 and the inner surface 39 of the cylindrical sieve 4 becomes narrower as it approaches the discharge port 44. It is configured.
The inner surface 39 of the cylindrical wall 40 and the tip of the blade 52 at the lowermost portion X of the cylindrical sieve 4 where the inner surface 39 of the rotating cylindrical sieve 4 and the tip of the blade 52 rotating together with the rotor 51 are closest. For example, the gap between the two is configured to be about 2 cm to 5 cm.

また、取付部７５及び取付部７７は、上下方向に移動可能なように図外の位置調整手段を介して設置面３０上に設けられており、当該位置調整手段を備えていることにより、ロータ５１の上下方向の傾斜角度を変更できるように構成されている。
また、軸受部７４及び軸受部７６の中心線とロータ５１の回転中心線５１Ｃとが一致するように、ロータ５１の一端側軸部５１ａが軸受部７６に回転可能に支持され、かつ、ロータ５１の他端側軸部５１ｂが軸受部７４に回転可能に支持されるように構成した。これにより、ロータ５１の上下方向の傾斜角度θ１を大きくした場合でも、軸受部７４及び軸受部７６の中心線とロータ５１の回転中心線５１Ｃとが一致する状態に維持できるようになり、ロータ５１をスムーズに回転させることができる。即ち、軸受部７４及び軸受部７６の中心線が水平となるように設置された軸受部７４及び軸受部７６にロータ５１の両端側の軸部を支持させてロータ５１の回転中心線５１Ｃの上下方向の傾斜角度を大きくした場合、ロータ５１の中央部と両端部とで回転中心の傾きが大きく異なるようになるため、ロータ５１を回転させることができなくなる。これに対して、実施形態１では、軸受部７４及び軸受部７６の中心線とロータ５１の回転中心線５１Ｃとが一致するように構成したので、ロータ５１の上下方向の傾斜角度を大きくした場合でも、軸受部７４及び軸受部７６の中心線とロータ５１の回転中心線５１Ｃとを一致させることができ、ロータ５１をスムーズに回転させることができるようになる。Further, the attachment portion 75 and the attachment portion 77 are provided on the installation surface 30 via position adjustment means (not shown) so as to be movable in the vertical direction, and the rotor is provided with the position adjustment means. It is comprised so that the inclination angle of the up-down direction of 51 can be changed.
Further, the one end side shaft portion 51a of the rotor 51 is rotatably supported by the bearing portion 76 so that the center line of the bearing portion 74 and the bearing portion 76 and the rotation center line 51C of the rotor 51 coincide with each other, and the rotor 51 The other end side shaft portion 51b is rotatably supported by the bearing portion 74. Accordingly, even when the vertical inclination angle θ1 of the rotor 51 is increased, the center line of the bearing portion 74 and the bearing portion 76 and the rotation center line 51C of the rotor 51 can be maintained to coincide with each other. Can be rotated smoothly. That is, the shaft portions on both ends of the rotor 51 are supported by the bearing portions 74 and the bearing portions 76 installed so that the center lines of the bearing portion 74 and the bearing portion 76 are horizontal, and the rotation center line 51C of the rotor 51 is vertically When the inclination angle of the direction is increased, the inclination of the rotation center is greatly different between the central portion and both end portions of the rotor 51, so that the rotor 51 cannot be rotated. On the other hand, in the first embodiment, since the center line of the bearing portion 74 and the bearing portion 76 is configured to coincide with the rotation center line 51C of the rotor 51, the vertical inclination angle of the rotor 51 is increased. However, the center line of the bearing part 74 and the bearing part 76 and the rotation center line 51C of the rotor 51 can be made to coincide with each other, and the rotor 51 can be smoothly rotated.

また、図３に示すように、ロータ５１の回転方向５１Ｒと円筒篩４の回転方向４Ｒとが逆方向となるように、ロータ５１及び円筒篩４を回転させる。
また、図外の投入コンベア等を用いて処理対象物（放射性物質や有害物質が付着した土砂や瓦礫等）が投入口４３まで搬送されて円筒篩４の内側に投入され、排出口４４から排出された篩分け処理後の処理対象物（再利用可能な土砂や瓦礫等）が図外の排出コンベア等により所定の場所に搬送される。Further, as shown in FIG. 3, the rotor 51 and the cylindrical sieve 4 are rotated so that the rotation direction 51R of the rotor 51 and the rotation direction 4R of the cylindrical sieve 4 are opposite to each other.
In addition, a processing object (such as earth and sand or debris to which radioactive substances or harmful substances are attached) is transported to the input port 43 using an input conveyor, etc., which is not shown, and is input to the inside of the cylindrical sieve 4 and discharged from the output port 44. The processed object (such as reusable earth and sand or debris) after the sieving process is conveyed to a predetermined place by a discharge conveyor or the like outside the figure.

以下、篩処理装置１の篩い分け動作について説明する。
まず、処理対象物を円筒篩４の投入口４３を介して円筒篩４の内側に投入し、円筒篩４を回転させるとともにロータ５１を回転させる。円筒篩４の内側に投入された処理対象物は、円筒篩４の回転によってかき混ぜられたり、羽根５２に衝突したりしながら、解砕されて、篩部４２の篩目より小さい粒径に砕かれた処理対象物は篩目を介して円筒篩４の下方に篩落とされ、篩目で篩落とされない処理対象物は円筒篩４の排出口４４側に移動する。
排出口４４側に移動する処理対象物は、排出口４４側に近付くに従って回転する円筒篩４の最下部分Ｘに近付くように位置されている羽根５２によって、篩目に押し付けられて擦り揉みされることで摩砕され、細かく摩砕された処理対象物は篩目を介して円筒篩４の下方に篩落とされる。Hereinafter, the sieving operation of the sieving apparatus 1 will be described.
First, the object to be treated is introduced into the inside of the cylindrical sieve 4 through the inlet 43 of the cylindrical sieve 4, and the rotor 51 is rotated while rotating the cylindrical sieve 4. The processing object thrown into the inside of the cylindrical sieve 4 is crushed while being stirred by the rotation of the cylindrical sieve 4 or colliding with the blades 52, and is crushed to a particle size smaller than the sieve mesh of the sieve part 42. The processed object thus passed is sieved down below the cylindrical sieve 4 through the sieve mesh, and the treatment object not sieved by the sieve mesh moves to the discharge port 44 side of the cylindrical sieve 4.
The object to be processed that moves to the discharge port 44 side is pressed and rubbed by the blades 52 that are positioned so as to approach the lowermost portion X of the cylindrical sieve 4 that rotates as it approaches the discharge port 44 side. Then, the processing object finely ground is sieved below the cylindrical sieve 4 through the mesh.

そして、円筒篩４の排出口４４側において、円筒篩４の回転により回転方向に移動する処理対象物が、回転する円筒篩４の最下部分Ｘにおいて、逆方向に回転するロータ５１の羽根５２と円筒篩４の篩部４２の内面３９とで押圧されて篩部４２の篩目に擦りつけられることにより、図４に示すように、例えば処理対象物Ｏに付着していた放射性物質や有害物質等の物質ａが篩目を形成する貫通孔４１，４１…を介して篩落とされるので、物質ａを効率的に篩落とすことができるようになり、放射性物質や有害物質等の物質ａが付着した土砂や瓦礫等の処理対象物Ｏを、放射性物質や有害物質の物質ａと再利用可能な土砂や瓦等とに確実に篩分けできるようになる。   Then, on the discharge port 44 side of the cylindrical sieve 4, the processing object that moves in the rotational direction by the rotation of the cylindrical sieve 4 is rotated at the lowermost part X of the rotating cylindrical sieve 4. 4 and the inner surface 39 of the sieve part 42 of the cylindrical sieve 4 and rubbed against the sieve of the sieve part 42, for example, as shown in FIG. Since the substance a such as a substance is sieved through the through holes 41, 41... Forming the sieve mesh, the substance a can be efficiently sieved, and the substance a such as a radioactive substance or a harmful substance can be removed. The object to be treated O such as adhering earth and sand or debris can be surely screened into radioactive substance or harmful substance a and reusable earth and sand or tile.

特に、円筒篩４の排出口４４側においては、ロータ５１の羽根５２と円筒篩４の内面３９との間の間隔Ｗ（図１参照）が狭くなるので、処理対象物が少なくなる円筒篩４の排出口４４側において、羽根５２が処理対象物を篩部４２の篩目に擦りつける動作を確実に行えるようになり、例えば処理対象物Ｏを放射性物質や有害物質の物質ａと再利用可能な土砂や瓦等とに確実に篩分けできるようになる。   In particular, on the discharge port 44 side of the cylindrical sieve 4, the interval W (see FIG. 1) between the blades 52 of the rotor 51 and the inner surface 39 of the cylindrical sieve 4 becomes narrow, so that the cylindrical sieve 4 that reduces the processing object. On the discharge port 44 side, the blade 52 can reliably perform the operation of rubbing the processing object on the screen of the sieving part 42. For example, the processing object O can be reused as a radioactive substance or a hazardous substance a. It can be surely sieved to earth and sand or tiles.

即ち、実施形態１によれば、円筒篩４の回転中心線４Ｃ及びロータ５１の回転中心線５１Ｃが、円筒篩４の投入口４３側から排出口４４側に向けて下るように傾斜するとともに、水平面Ｈに対するロータ５１の回転中心線５１Ｃの傾斜角度θ１が水平面Ｈに対する円筒篩４の回転中心線４Ｃの傾斜角度θ２よりも大きくなるように構成したので、円筒篩４の排出口４４側において、ロータ５１の羽根５２と円筒篩４の内面３９との間の間隔Ｗを狭くできるようになり、排出口４４側に近付くほどロータ５１の羽根５２が処理対象物を円筒篩４の内面３９に押し付ける力が弱くなってしまうことを抑制できるので、処理対象物が少なくなる円筒篩４の排出口４４側において、羽根５２が処理対象物を篩部４２の篩目に擦りつける動作を確実に行えるようになり、処理対象物を効率的に篩分けできるようになる。
つまり、実施形態１では、特許文献１のような、円筒篩の回転中心線とロータの回転中心線とが平行である場合のように、円筒篩の排出口側に近付くほど、ロータの羽根が処理対象物を円筒篩の篩目に押し付ける力が弱くなるので、当該羽根が空回りしやすくなって、ロータの羽根が処理対象物を円筒篩の篩目に押し付けることによる擦り付け動作が行われなくなるという問題を解消できるようになった。That is, according to the first embodiment, the rotation center line 4C of the cylindrical sieve 4 and the rotation center line 51C of the rotor 51 are inclined so as to be lowered from the inlet 43 side to the outlet 44 side of the cylindrical sieve 4, Since the inclination angle θ1 of the rotation center line 51C of the rotor 51 with respect to the horizontal plane H is configured to be larger than the inclination angle θ2 of the rotation center line 4C of the cylindrical sieve 4 with respect to the horizontal plane H, on the discharge port 44 side of the cylindrical sieve 4 The space W between the blade 52 of the rotor 51 and the inner surface 39 of the cylindrical sieve 4 can be reduced, and the blade 52 of the rotor 51 presses the object to be processed against the inner surface 39 of the cylindrical screen 4 as it approaches the discharge port 44 side. Since the force can be suppressed from being weakened, the blade 52 can reliably perform the operation of rubbing the processing object on the screen of the sieving part 42 on the discharge port 44 side of the cylindrical sieve 4 where the processing object is reduced. Thus, the object to be processed can be efficiently screened.
That is, in Embodiment 1, as the rotation center line of the cylindrical sieve and the rotation center line of the rotor are parallel to each other as in Patent Document 1, the blades of the rotor become closer to the discharge port side of the cylindrical sieve. Since the force to press the object to be processed on the sieve of the cylindrical sieve is weakened, the blades are easy to idle, and the rotor blade is not rubbed by pressing the object to be processed on the sieve of the cylindrical sieve. The problem can be solved.

実施形態２
図１に示すように、実施形態１と同様に、円筒篩４の回転中心線４Ｃ及びロータ５１の回転中心線５１Ｃが、円筒篩４の投入口４３側から排出口４４側に向けて下るように傾斜するとともに、水平面Ｈに対するロータ５１の回転中心線５１Ｃの傾斜角度θ１が水平面Ｈに対する円筒篩４の回転中心線４Ｃの傾斜角度θ２よりも大きくなるように構成するとともに、図５（ｂ）に示すように、円筒篩４の排出口４４の前方Ｂ側から篩処理装置１を見た場合において、円筒篩４の排出口４４側のロータ５１の回転中心線５１Ｃが、円筒篩４の回転中心線４Ｃを通過する垂直線Ｖの位置よりも左側にずれて位置された構成とした。Embodiment 2
As shown in FIG. 1, the rotation center line 4C of the cylindrical sieve 4 and the rotation center line 51C of the rotor 51 are lowered from the inlet 43 side of the cylindrical sieve 4 toward the outlet 44 as in the first embodiment. And the inclination angle θ1 of the rotation center line 51C of the rotor 51 with respect to the horizontal plane H is larger than the inclination angle θ2 of the rotation center line 4C of the cylindrical sieve 4 with respect to the horizontal plane H, and FIG. When the sieving apparatus 1 is viewed from the front B side of the discharge port 44 of the cylindrical sieve 4, the rotation center line 51 </ b> C of the rotor 51 on the discharge port 44 side of the cylindrical sieve 4 is It was set as the structure shifted | deviated to the left side from the position of the vertical line V which passes 4C of centerlines.

つまり、円筒篩４の投入口４３側においては、図５（ｃ）に示すように、ロータ５１の回転中心線５１Ｃの位置が円筒篩４の回転中心線４Ｃを通過する垂直線Ｖ上又は垂直線Ｖの近傍に位置され、かつ、円筒篩４の排出口４４側においては、図５（ｂ）に示すように、ロータ５１の回転中心線５１Ｃの位置が、円筒篩４の回転中心線４Ｃを通過する垂直線Ｖ上における回転中心線４Ｃの真下位置から回転篩４の回転方向４Ｒにずれた位置に位置された構成とした。   That is, on the inlet 43 side of the cylindrical sieve 4, as shown in FIG. 5C, the position of the rotation center line 51C of the rotor 51 is above or perpendicular to the vertical line V passing through the rotation center line 4C of the cylindrical sieve 4. As shown in FIG. 5B, the rotation center line 51 </ b> C of the rotor 51 is positioned near the line V and on the discharge port 44 side of the cylindrical sieve 4. It is set as the structure located in the position which shifted | deviated to the rotation direction 4R of the rotary sieve 4 from the position right under the rotation center line 4C on the vertical line V which passes through.

即ち、図５（ａ）に示すように、ロータ５１の回転中心線５１Ｃと円筒篩４の回転中心線４Ｃとの関係を上方から見た場合、ロータ５１の回転中心線５１Ｃが円筒篩４の回転中心線４Ｃに対して左右方向に傾斜するように配置して、円筒篩４の排出口４４側においては、ロータ５１の回転中心線５１Ｃの位置が円筒篩４の回転中心線４Ｃの位置から円筒篩４の左側にずれた構成とした。尚、図５（ａ）では、円筒篩４の篩部４２を形成する貫通孔４１の図示を省略している。   That is, as shown in FIG. 5A, when the relationship between the rotation center line 51C of the rotor 51 and the rotation center line 4C of the cylindrical sieve 4 is viewed from above, the rotation center line 51C of the rotor 51 is It arrange | positions so that it may incline in the left-right direction with respect to the rotation centerline 4C, and the position of the rotation centerline 51C of the rotor 51 is from the position of the rotation centerline 4C of the cylindrical sieve 4 in the discharge port 44 side of the cylindrical sieve 4. The configuration was shifted to the left side of the cylindrical sieve 4. In FIG. 5A, illustration of the through hole 41 that forms the sieve portion 42 of the cylindrical sieve 4 is omitted.

例えば、図５（ｂ）に示すように、Ｂ側から篩処理装置１を見て、ロータ５１の回転方向５１Ｒが反時計回り（左回転）、円筒篩４の回転方向４Ｒが時計回り（右回転）するように構成されるとともに、ロータ５１の回転中心線５１Ｃの位置を円筒篩４の回転中心線４Ｃの真下位置から回転篩４の回転方向にずれた位置に設定して、回転する円筒篩４の筒壁４０の内面３９とロータ５１とともに回転する羽根５２の先端とが最も接近する位置が、回転する円筒篩４の下部左側の部分Ｘ１となるように構成した。
尚、図５（ｃ）に示すように、Ａ側から篩処理装置１を見て、ロータ５１の回転方向５１Ｒが時計回り（右回転）、円筒篩４の回転方向４Ｒが反時計回り（左回転）するように構成される。
また、回転する円筒篩４の筒壁４０の内面３９とロータ５１とともに回転する羽根５２の先端とが最も接近する円筒篩４の下部左側の部分Ｘ１での筒壁４０の内面３９と羽根５２の先端との間の隙間は、例えば２ｃｍ〜５ｃｍ程度となるように構成されている。For example, as shown in FIG. 5 (b), when the sieving apparatus 1 is viewed from the B side, the rotation direction 51R of the rotor 51 is counterclockwise (left rotation), and the rotation direction 4R of the cylindrical sieve 4 is clockwise (right). The rotation center line 51C of the rotor 51 is set to a position shifted from the position directly below the rotation center line 4C of the cylindrical sieve 4 in the rotation direction of the rotary sieve 4, and the rotating cylinder The position where the inner surface 39 of the cylindrical wall 40 of the sieve 4 and the tip of the blade 52 rotating together with the rotor 51 are closest is the lower left portion X1 of the rotating cylindrical sieve 4.
As shown in FIG. 5C, when the sieving apparatus 1 is viewed from the A side, the rotation direction 51R of the rotor 51 is clockwise (right rotation), and the rotation direction 4R of the cylindrical sieve 4 is counterclockwise (left). Configured to rotate).
Further, the inner surface 39 of the cylindrical wall 40 and the inner surface 39 of the blade 52 at the lower left portion X1 of the cylindrical sieve 4 where the inner surface 39 of the cylindrical wall 40 of the rotating cylindrical screen 4 and the tip of the blade 52 rotating together with the rotor 51 are closest. The gap between the tips is configured to be, for example, about 2 cm to 5 cm.

実施形態２によれば、ロータ５１の回転方向５１Ｒと円筒篩４の回転方向４Ｒとが逆方向となるように構成されるとともに、円筒篩４の排出口４４側において、ロータ５１の回転中心線５１Ｃが、円筒篩４の回転中心線４Ｃを通過する垂直線Ｖの位置よりも左側又は右側にずれて位置された構成としたことにより、円筒篩４の排出口４４側において、円筒篩４の回転によって下方から上方に移動する処理対象物が、円筒篩４とは反対方向に回転するロータ５１の羽根５２によって篩部４２の篩目に擦りつけられることになる。つまり、円筒篩４の回転によって下方から上方に移動しようとする処理対象物が、上方から下方に回転移動する羽根５２に衝突するので、筒壁４０の内面３９と羽根５２の先端とが最も接近する円筒篩４の下部左側の部分Ｘ１において処理対象物に対する押圧力（衝撃力）が大きくなり、羽根５２が処理対象物を篩部４２の篩目に擦りつける動作を確実かつ効果的に行えるようになり、処理対象物を効率的に篩分けできるようになる。   According to the second embodiment, the rotational direction 51R of the rotor 51 and the rotational direction 4R of the cylindrical sieve 4 are configured to be opposite directions, and the rotational center line of the rotor 51 is disposed on the discharge port 44 side of the cylindrical sieve 4. 51C is configured to be shifted to the left or right side of the position of the vertical line V passing through the rotation center line 4C of the cylindrical sieve 4 so that the cylindrical sieve 4 The object to be processed that moves from the lower side to the upper side by the rotation is rubbed against the sieve of the sieve part 42 by the blades 52 of the rotor 51 that rotates in the opposite direction to the cylindrical sieve 4. That is, the object to be processed that moves upward from below by the rotation of the cylindrical sieve 4 collides with the blade 52 that rotates downward from above, so that the inner surface 39 of the cylindrical wall 40 and the tip of the blade 52 are closest to each other. The pressing force (impact force) on the object to be processed increases in the lower left portion X1 of the cylindrical sieve 4 to be performed so that the blade 52 can reliably and effectively perform the operation of rubbing the object to be processed on the sieve of the sieve part 42. Thus, the object to be processed can be efficiently screened.

尚、ロータ５１の回転方向５１Ｒ及び円筒篩４の回転方向４Ｒが上記とは反対方向に設定された場合においては、図５（ａ）の円筒篩４の排出口４４のＢ側から篩処理装置１を見た場合において、ロータ５１の回転中心線５１Ｃが、円筒篩４の回転中心線４Ｃを通過する垂直線Ｖの位置よりも右側にずれて位置された構成とすればよい。   In the case where the rotation direction 51R of the rotor 51 and the rotation direction 4R of the cylindrical sieve 4 are set in the opposite direction to the above, the sieving apparatus from the B side of the discharge port 44 of the cylindrical sieve 4 in FIG. 1, the rotation center line 51C of the rotor 51 may be shifted to the right side from the position of the vertical line V passing through the rotation center line 4C of the cylindrical sieve 4.

実施形態３
実施形態２のように、排出口４４側においてロータ５１の回転中心線５１Ｃの位置を円筒篩４の回転中心線４Ｃを通過する垂直線Ｖの位置から左側又は右側にずらした構成とした場合、円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなるような負荷がロータ５１に加わる可能性がある。
この場合、排出口４４側において円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなる前に、ロータ５１を円筒篩４の内面３９から離れる方向に逃がす機構を設けることが好ましい。
しかしながら、ロータ５１の回転中心線５１Ｃが円筒篩４の回転中心線４Ｃに対して傾斜するように配置されて、かつ、円筒篩４の排出口４４側において、ロータ５１の回転中心線５１Ｃの位置を円筒篩４の回転中心線の位置から円筒篩４の左側又は右側にずらした実施形態２の構成の場合、円筒篩４の排出口４４側のロータ５１を真上方向に逃がす機構を用いた場合、羽根５２が円筒篩４の内面３９に衝突してしまう。
そこで、実施形態３では、円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなる前に、ロータ５１を後述するヒンジ機構８３を回転中心として回転させて円筒篩４の中央側に逃がすようにして、羽根５２が円筒篩４の内面３９に衝突しないようにした。Embodiment 3
As in the second embodiment, when the position of the rotation center line 51C of the rotor 51 is shifted to the left or right side from the position of the vertical line V passing through the rotation center line 4C of the cylindrical sieve 4 on the discharge port 44 side, There is a possibility that a load is applied to the rotor 51 such that a large stone or the like is sandwiched between the cylindrical sieve 4 and the blade 52 and the rotor 51 does not rotate.
In this case, a mechanism for allowing the rotor 51 to escape in a direction away from the inner surface 39 of the cylindrical sieve 4 is provided before a large stone or the like is sandwiched between the cylindrical sieve 4 and the blade 52 on the discharge port 44 side and the rotor 51 does not rotate. It is preferable.
However, the rotation center line 51C of the rotor 51 is disposed so as to be inclined with respect to the rotation center line 4C of the cylindrical sieve 4, and the position of the rotation center line 51C of the rotor 51 is on the discharge port 44 side of the cylindrical sieve 4. In the case of the configuration of Embodiment 2 where the position of the rotation center line of the cylindrical sieve 4 is shifted to the left side or the right side of the cylindrical sieve 4, a mechanism for allowing the rotor 51 on the discharge port 44 side of the cylindrical sieve 4 to escape upward is used. In this case, the blade 52 collides with the inner surface 39 of the cylindrical sieve 4.
Therefore, in the third embodiment, before a large stone or the like is sandwiched between the cylindrical sieve 4 and the blades 52 and the rotor 51 does not rotate, the rotor 51 is rotated about a hinge mechanism 83 described later as the center of rotation, so that the cylindrical sieve 4 So that the blade 52 does not collide with the inner surface 39 of the cylindrical sieve 4.

実施形態３においては、図６，図７（ａ）に示すように、圧力付与手段回転駆動支持機構７の他端側回転支持部７２Ａは、ロータ５１の他端側軸部５１ｂを回転可能に支持する軸受部７４と、ロータ負荷軽減機構８０とを備える。
ロータ負荷軽減機構８０は、円筒篩４の排出口４４側に位置されるロータ５１を円筒篩４の内面３９から離れる方向及び円筒篩４の内面３９に近付く方向に移動可能とする機構であって、例えば、軸受部７４及び回転駆動源７３が設置された設置板８１と、設置面３０上に設けられた基板８２と、設置板８１の一端側と基板８２の一端側とを連結するヒンジ機構８３と、基板８２の他端側より突出するように設けられて設置板８１の他端側を支持する支持部８４とを備える。In the third embodiment, as shown in FIGS. 6 and 7A, the other end side rotation support portion 72A of the pressure applying means rotation drive support mechanism 7 can rotate the other end side shaft portion 51b of the rotor 51. The bearing part 74 to support and the rotor load reduction mechanism 80 are provided.
The rotor load reduction mechanism 80 is a mechanism that allows the rotor 51 positioned on the discharge port 44 side of the cylindrical sieve 4 to move in a direction away from the inner surface 39 of the cylindrical sieve 4 and a direction approaching the inner surface 39 of the cylindrical sieve 4. For example, the installation plate 81 in which the bearing portion 74 and the rotation drive source 73 are installed, the substrate 82 provided on the installation surface 30, and the hinge mechanism that connects one end side of the installation plate 81 and one end side of the substrate 82. 83 and a support portion 84 provided so as to protrude from the other end side of the substrate 82 and supporting the other end side of the installation plate 81.

また、実施形態３においては、図６，図８（ａ）に示すように、一端側回転支持部７１Ａは、ロータ５１の一端側軸部５１ａを回転可能に支持する軸受部７６と、ロータ負荷軽減機構９０とを備える。
ロータ負荷軽減機構９０は、ロータ負荷軽減機構８０が作動した場合に、ロータ５１の他端側の動きにロータ５１の一端側の動きを追随させるための機構であって、例えば、軸受部７６が設置された設置板９１と、設置面３０上に設けられた基板９２と、設置板９１の一端側と基板９２の一端側とを連結するヒンジ機構９３と、基板９２の他端側より突出するように設けられて設置板９１の他端側を支持する支持部９４とを備える。In the third embodiment, as shown in FIGS. 6 and 8A, the one end side rotation support portion 71A includes a bearing portion 76 that rotatably supports the one end side shaft portion 51a of the rotor 51, and a rotor load. A mitigation mechanism 90.
The rotor load reduction mechanism 90 is a mechanism for causing the movement of the one end side of the rotor 51 to follow the movement of the other end side of the rotor 51 when the rotor load reduction mechanism 80 is operated. The installed plate 91, the substrate 92 provided on the installation surface 30, a hinge mechanism 93 that connects one end side of the installed plate 91 and one end side of the substrate 92, and protrudes from the other end side of the substrate 92. And a support portion 94 that supports the other end side of the installation plate 91.

実施形態３においては、ロータ負荷軽減機構８０を備えているため、円筒篩４の排出口４４側で円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなる前に、ロータ５１の他端側が、図７（ｂ）に示すように、円筒篩４の内面３９から離れる方向に逃げ、かつ、円筒篩４の投入口４３側においては、ロータ負荷軽減機構９０を備えているため、図８（ｂ）に示すように、ロータ５１の一端側がロータ５１の他端側の動きに追従して動くので、排出口４４側で円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなるような事態を防止でき、ロータ５１に大きな負荷が加わることを防止できるようになるので、ロータ５１の破損や回転駆動源７３の故障等を防止できるようになる。   In the third embodiment, since the rotor load reduction mechanism 80 is provided, before the rotor 51 stops rotating due to a large stone or the like sandwiched between the cylindrical sieve 4 and the blade 52 on the discharge port 44 side of the cylindrical sieve 4. The other end side of the rotor 51 escapes away from the inner surface 39 of the cylindrical sieve 4 as shown in FIG. 7B, and a rotor load reducing mechanism 90 is provided on the inlet 43 side of the cylindrical sieve 4. Therefore, as shown in FIG. 8B, one end side of the rotor 51 moves following the movement of the other end side of the rotor 51, so that a large gap is formed between the cylindrical sieve 4 and the blade 52 on the discharge port 44 side. Since it is possible to prevent a situation in which the rotor 51 does not rotate due to a stone or the like being sandwiched, and a large load can be prevented from being applied to the rotor 51, damage to the rotor 51, failure of the rotational drive source 73, and the like can be prevented. become.

即ち、実施形態３では、排出口４４側においてロータ５１の回転中心線５１Ｃの位置を円筒篩４の回転中心線４Ｃの位置から円筒篩４の右側又は左側にずらした構成で、円筒篩４と羽根５２との間に大きな石等が挟まってロータ５１が回転しなくなる前に、ロータ５１を真上方向に逃がすのではなく、ロータ５１をヒンジ機構８３を回転中心として回転させて円筒篩４の中央側に移動させるようにすることで、羽根５２が円筒篩４の内面３９に衝突しないように構成したものである。   That is, in the third embodiment, the position of the rotation center line 51C of the rotor 51 on the discharge port 44 side is shifted from the position of the rotation center line 4C of the cylindrical sieve 4 to the right side or the left side of the cylindrical sieve 4, Before the rotor 51 does not rotate due to a large stone or the like sandwiched between the blades 52, the rotor 51 is not allowed to escape directly upward, but the rotor 51 is rotated about the hinge mechanism 83 as the center of rotation. The blade 52 is configured not to collide with the inner surface 39 of the cylindrical sieve 4 by being moved to the center side.

尚、基板８２及び基板９２は、左右方向及び上下方向に移動可能なように図外の位置調整手段を介して設置手段３上に設けられている。当該位置調整手段を備えていることにより、ロータ５１の上下方向の傾斜角度、及び、ロータ５１の左右方向の傾斜角度を変更できるように構成されている。   The substrate 82 and the substrate 92 are provided on the installation means 3 via position adjustment means (not shown) so as to be movable in the left-right direction and the vertical direction. By including the position adjusting means, the vertical inclination angle of the rotor 51 and the horizontal inclination angle of the rotor 51 can be changed.

実施形態４

即ち、羽根５２は、ロータ５１からの突出量が、円筒篩４の投入口４３側では短く、かつ、円筒篩４の排出口４４側では長い構成としたことで、円筒篩４の排出口４４側においては、ロータ５１の羽根５２と円筒篩４の内面３９（篩部４２の内面３９）との間の間隔Ｗを狭くできる。このため、投入口４３側においては短い羽根５２と円筒篩４の内面３９との間に処理対象物を多く取り込むことができ、処理対象物の量が少なくなってくる排出口４４側では羽根５２の長さが長いので、ロータ５１の羽根５２が処理対象物を円筒篩４の篩部４２に擦り付ける動作を確実に行うことができるようになる。つまり、排出口４４側に近付くほど、ロータ５１の羽根５２が処理対象物を円筒篩４の篩部４２に押し付ける力が弱くなってしまうことを抑制でき、処理対象物を効率的に篩分けることができる。
従って、実施形態４によれば、処理対象物の投入量を多くできるとともに、処理対象物の量が少なくなってくる排出口４４側において、羽根５２が処理対象物を篩部４２の篩目に擦りつける動作を確実に行えるようになり、処理対象物を効率的に篩分けできる。Embodiment 4

That is, the blade 52 has a structure in which the amount of protrusion from the rotor 51 is short on the side of the inlet 43 of the cylindrical sieve 4 and long on the side of the outlet 44 of the cylindrical sieve 4. On the side, the interval W between the blades 52 of the rotor 51 and the inner surface 39 of the cylindrical sieve 4 (the inner surface 39 of the sieve part 42) can be reduced. Therefore, a large amount of processing object can be taken in between the short blade 52 and the inner surface 39 of the cylindrical sieve 4 on the input port 43 side, and the blade 52 on the discharge port 44 side where the amount of the processing object decreases. Therefore, the blade 52 of the rotor 51 can reliably perform the operation of rubbing the object to be processed against the sieve portion 42 of the cylindrical sieve 4. That is, it can suppress that the force which the blade | wing 52 of the rotor 51 presses a process target object on the sieve part 42 of the cylindrical sieve 4 becomes weak, so that it approaches the discharge port 44 side, and sifts a process target object efficiently. Can do.
Therefore, according to the fourth embodiment, it is possible to increase the input amount of the processing object, and on the discharge port 44 side where the amount of the processing object decreases, the blade 52 causes the processing object to pass through the sieve portion 42.
