Abstract

<P>PROBLEM TO BE SOLVED: To provide a horizontal crusher capable of satisfactorily biting and crushing even a flat plate-like material to be crushed. <P>SOLUTION: A crush board 6 which faces an outer circular locus A of crushing rings 5 externally fit to multiple rods 4 set on a circle of a same pitch between a pair of rotors 3 rotatingly driven around a horizontal main spindle 2, is overhangingly tilted toward the outer circular locus A of the crushing rings 5 at a position higher than the height position of the approximate shaft center of the main spindle 2 of the rotors 3. The biting angle of the material M to be crushed is made smaller by a tilting angle of the crushing board 6, thereby biting and crushing the material M even when the material M is a flat plate. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、被破砕物を圧縮力で破砕する横型破砕機に関するものである。   The present invention relates to a horizontal crusher that crushes an object to be crushed with a compressive force.

被破砕物を圧縮力で破砕する破砕機には、ケーシングの左右両側で水平主軸の回りに回転駆動される一対のロータと、これらのロータ間に同一ピッチ円上で差し渡された複数本のロッドと、これらのロッドに回転自在に外嵌され、ロータの回転に伴って円軌跡を描いて移動する破砕リングと、この破砕リングが下方へ移動する円軌跡の前面側に対向させた破砕板とを備え、被破砕物をこの破砕板と円軌跡を下方へ移動する破砕リングとの間に噛み込ませて圧縮力により破砕し、破砕された被破砕物を破砕リングの円軌跡の下方に配設された円弧状のスクリーンから排出するようにした横型破砕機がある(例えば、特許文献1参照。)。また、少しタイプが異なるが、破砕リングの替りに、水平主軸の回りに回転駆動される破砕ローラを設け、被破砕物を破砕ローラと破砕板との間に噛み込ませて圧縮力により破砕する横型破砕機もある(例えば、特許文献2参照。)。   The crusher that crushes the object to be crushed with compressive force includes a pair of rotors that are driven to rotate around the horizontal main shaft on both the left and right sides of the casing, and a plurality of rotors that are passed between these rotors on the same pitch circle. Rods, a crushing ring that is rotatably fitted to these rods and moves in a circular locus along with the rotation of the rotor, and a crushing plate opposed to the front side of the circular locus in which the crushing ring moves downward The object to be crushed is caught between the crushing plate and the crushing ring moving downward along the circular locus, and crushed by compressive force, and the crushed object to be crushed below the circular locus of the crushing ring. There is a horizontal crusher that discharges from an arranged arcuate screen (see, for example, Patent Document 1). Also, although the type is slightly different, a crushing roller that is driven to rotate around the horizontal main shaft is provided instead of the crushing ring, and the object to be crushed is caught between the crushing roller and the crushing plate and crushed by compressive force. There is also a horizontal crusher (for example, refer to Patent Document 2).

このような横型破砕機では、破砕板と破砕リングの外側円軌跡または破砕ローラの外径円とで被破砕物の噛み込み角度、すなわち、被破砕物が噛み込まれる入口での破砕板と破砕リングの外側円軌跡または破砕ローラの外径円の接線とがなす角度が決まる。噛み込み角度は被破砕物の厚み寸法によって変化し、被破砕物の厚み寸法が大きくなって噛み込み角度が大きくなると、被破砕物が押し戻されて噛み込まれなくなる限界噛み込み角度が存在する。この限界噛み込み角度は、被破砕物が岩石等のように凹凸のある場合は30°程度と大きいが、被破砕物が平坦な板状のものの場合は20°程度と小さくなって、噛み込まれ難くなる。   In such a horizontal crusher, the biting angle of the object to be crushed by the outer circular locus of the crushing plate and the crushing ring or the outer diameter circle of the crushing roller, that is, the crushing plate and crushing at the entrance where the object to be crushed is bitten The angle formed by the outer circle locus of the ring or the tangent of the outer diameter circle of the crushing roller is determined. The biting angle varies depending on the thickness dimension of the object to be crushed. When the thickness dimension of the object to be crushed increases and the biting angle increases, there is a limit biting angle at which the object to be crushed is pushed back and is not bitten. This limit biting angle is as large as about 30 ° when the object to be crushed is uneven, such as rocks, but becomes as small as about 20 ° when the object to be crushed is a flat plate. It becomes difficult to be rare.

特開平11−90250号公報(第3頁、第1図)JP-A-11-90250 (page 3, FIG. 1) 特開平9−122512号公報(第2−4頁、第1図)JP-A-9-122512 (page 2-4, FIG. 1)

上述した特許文献1に記載の横型破砕機は、破砕板が垂直なため、厚い平坦な板状の被破砕物を破砕する場合は、噛み込み角度が限界噛み込み角度よりも大きくなって、被破砕物の噛み込み性が悪くなる問題がある。噛み込み角度を小さくする手段としては、例えば、圧延機における圧延ロールの直径を大きくするように、破砕リングの外側円軌跡の直径を大きくすることが考えられるが、十分に噛み込み角度を小さくするためには、破砕リングの外側円軌跡の直径をかなり大きくする必要があり、破砕機の断面寸法が非常に大きなものとなる。   In the horizontal crusher described in Patent Document 1 described above, since the crushing plate is vertical, when crushing a thick flat plate-shaped crushing object, the biting angle becomes larger than the limit biting angle, There is a problem that the biting property of the crushed material is deteriorated. As a means for reducing the biting angle, for example, it is conceivable to increase the diameter of the outer circular locus of the crushing ring so as to increase the diameter of the rolling roll in the rolling mill. However, the biting angle should be sufficiently reduced. For this purpose, it is necessary to considerably increase the diameter of the outer circular locus of the crushing ring, and the cross-sectional dimension of the crusher becomes very large.

また、特許文献2に記載された横型破砕機は、破砕板に破砕ローラの外周面に沿って下方に延びる円弧状の破砕面を設けているが、この円弧状破砕面の上方は垂直な破砕面で形成されているので、厚い被破砕物の噛み込み入口が垂直な破砕面の部位となる場合は、特許文献1に記載のものと同様に、被破砕物の噛み込み性が悪くなる。   Moreover, the horizontal crusher described in Patent Document 2 is provided with an arc-shaped crushing surface extending downward along the outer peripheral surface of the crushing roller on the crushing plate. Since it is formed by the surface, when the biting inlet of the thick object to be crushed becomes a part of the vertical crushing surface, the biting property of the object to be crushed is deteriorated as in the case of Patent Document 1.

そこで、本発明の課題は、平坦な板状の被破砕物であっても、良好に噛み込んで破砕できる横型破砕機を提供することである。   Accordingly, an object of the present invention is to provide a horizontal crusher that can satisfactorily bite and crush even a flat plate-shaped object to be crushed.

上記の課題を解決するために、本発明は、ケーシングの左右両側で水平主軸の回りに回転駆動される一対のロータと、これらのロータ間に同一ピッチ円上で差し渡された複数本のロッドと、これらのロッドに回転自在に外嵌され、前記ロータの回転に伴って円軌跡を描いて移動する破砕リングと、この破砕リングが下方へ移動する円軌跡の前面側に対向させた破砕板とを備え、被破砕物をこの破砕板と円軌跡を下方へ移動する破砕リングとの間に噛み込ませて圧縮力により破砕し、破砕された被破砕物を前記破砕リングの円軌跡の下方に配設された円弧状のスクリーンから排出する横型破砕機において、前記破砕板を前記水平主軸の略軸心の高さ位置よりも上方で、前記破砕リングの円軌跡側へオーバハング状に傾斜させた構成を採用した。   In order to solve the above-described problems, the present invention provides a pair of rotors that are driven to rotate around a horizontal main shaft on both the left and right sides of a casing, and a plurality of rods that are passed between these rotors on the same pitch circle. A crushing ring that is rotatably fitted to these rods and moves along a circular locus along with the rotation of the rotor, and a crushing plate opposed to the front side of the circular locus where the crushing ring moves downward And crushing the object to be crushed between the crushing plate and a crushing ring that moves downward along the circular locus, and crushing the object by compressive force. In the horizontal crusher that discharges from the arc-shaped screen disposed in the chamfer, the crushing plate is inclined in an overhanging manner toward the circular locus side of the crushing ring above the height position of the substantially axial center of the horizontal main shaft. Adopted.

すなわち、破砕板をロータの水平主軸の略軸心の高さ位置よりも上方で、破砕リングの円軌跡側へオーバハング状に傾斜させることにより、被破砕物の噛み込み角度を破砕板の傾斜角度分だけ小さくし、被破砕物の噛み込み性を良好に確保できるようにした。   In other words, the crushing plate is tilted overhanging toward the circular trajectory side of the crushing ring above the height of the substantially central axis of the horizontal main shaft of the rotor, so that the biting angle of the object to be crushed is set to the inclination angle of the crushing plate. The size was reduced by an amount corresponding to the material to be crushed to ensure good biting properties.

前記被破砕物が板状のものである場合は、この板状被破砕物が2枚重なって前記破砕板と破砕リングとの間に噛み込まれることを想定したときの、前記破砕リングの外側円軌跡と破砕板とで形成される想定噛み込み角度を20°以下、好ましくは18°以下とするのがよい。平坦な板状被破砕物の限界噛み込み角度は20°程度であり、板状被破砕物は2枚重なって噛み込まれることが多いからである。   When the object to be crushed is a plate-like object, the outer side of the crushing ring when it is assumed that two pieces of the plate-like object to be crushed overlap each other and are bitten between the crushing plate and the crushing ring. The assumed biting angle formed by the circular locus and the crushing plate is 20 ° or less, preferably 18 ° or less. This is because the flat biting object has a limit biting angle of about 20 °, and two plate-like crushing objects are often bitten in layers.

前記破砕リングの外側円軌跡と前記スクリーンとの隙間を、前記板状被破砕物の板厚の2倍以内とすることにより、スクリーンとの隙間でも被破砕物に圧縮力を作用させ、より確実に被破砕物を破砕することができる。   By setting the gap between the outer circular locus of the crushing ring and the screen to be within twice the plate thickness of the plate-like crushing object, a compressive force is applied to the crushing object even in the gap with the screen, thereby ensuring more reliability. The material to be crushed can be crushed.

前記板状被破砕物が異なる材質層を有する複合材である場合は、前記破砕リングの外周面に複数の突起を設けることにより、突起が接触する部位と接触しない部位との境界で、被破砕物に剪断力を作用させ、複合材を効率よく分離することができる。   When the plate-shaped object to be crushed is a composite material having different material layers, by providing a plurality of protrusions on the outer peripheral surface of the crushing ring, the object to be crushed at the boundary between the part where the protrusions contact and the part where the protrusions do not contact By applying a shearing force to the object, the composite material can be separated efficiently.

本発明の横型破砕機は、破砕板をロータの水平主軸の略軸心の高さ位置よりも上方で、破砕リングの円軌跡側へオーバハング状に傾斜させるようにしたので、被破砕物の噛み込み角度を破砕板の傾斜角度分だけ小さくし、被破砕物の噛み込み性を良好に確保することができる。   In the horizontal crusher of the present invention, the crushing plate is inclined in an overhanging manner toward the circular trajectory side of the crushing ring above the height position of the substantially central axis of the horizontal main shaft of the rotor. The insertion angle is reduced by the inclination angle of the crushing plate, and the biting property of the object to be crushed can be ensured satisfactorily.

前記被破砕物が板状のものである場合は、この板状被破砕物が2枚重なって破砕板と破砕リングとの間に噛み込まれることを想定したときの、破砕リングの外側円軌跡と破砕板とで形成される想定噛み込み角度を20°以下、好ましくは18°以下とすることにより、限界噛み込み角度が小さく、かつ、2枚重なって噛み込まれることが多い板状被破砕物であっても、良好な噛み込み性を確保することができる。   When the object to be crushed is a plate-like object, the outer circular locus of the crushing ring when it is assumed that two pieces of the plate-like object to be crushed overlap and are bitten between the crushing plate and the crushing ring. By making the assumed biting angle formed by the crushing plate 20 ° or less, preferably 18 ° or less, the limit biting angle is small and the plate-like crushing that is often bitten in two overlapping layers Even if it is a thing, favorable biting property can be ensured.

前記破砕リングの外側円軌跡とスクリーンとの隙間を、板状被破砕物の板厚の2倍以内とすることにより、スクリーンとの隙間でも被破砕物に圧縮力を作用させ、より確実に被破砕物を破砕することができる。   By setting the gap between the outer circular locus of the crushing ring and the screen to be less than twice the plate thickness of the plate-like object to be crushed, a compressive force is applied to the object to be crushed even in the gap with the screen. The crushed material can be crushed.

前記板状被破砕物が異なる材質層を有する複合材である場合は、破砕リングの外周面に複数の突起を設けることにより、突起が接触する部位と接触しない部位との境界で、被破砕物に剪断力を作用させ、複合材を効率よく分離することができる。   When the plate-shaped object to be crushed is a composite material having different material layers, by providing a plurality of protrusions on the outer peripheral surface of the crushing ring, the object to be crushed at the boundary between the part where the protrusions contact and the part where the protrusions do not contact By applying a shearing force to the composite material, the composite material can be separated efficiently.

以下、図面に基づき、本発明の実施形態を説明する。この横型破砕機は、図1および図2に示すように、ケーシング1の左右両側で水平主軸2の回りに回転駆動される一対のロータ3と、これらのロータ3間に同一ピッチ円上で差し渡された複数本のロッド4と、各ロッド4に回転自在に外嵌され、ロータ3の回転に伴って円軌跡を描いて移動する破砕リング5と、破砕リング5が下方へ移動する円軌跡の前面側に対向させた破砕板6とを備え、上方から投入される被破砕物Mを、破砕リング5の外側円軌跡Aの前面側と破砕板6との間に噛み込ませて圧縮力により破砕し、破砕された被破砕物Mを破砕リング5の外側円軌跡Aの下方に配設された円弧状のスクリーン7の孔7aから排出するものである。各破砕リング5の外周面には、複数のカマボコ状突起5aが千鳥状に設けられている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the horizontal crusher includes a pair of rotors 3 that are rotationally driven around the horizontal main shaft 2 on both the left and right sides of the casing 1, and a gap between the rotors 3 on the same pitch circle. A plurality of passed rods 4, a crushing ring 5 that is rotatably fitted around each rod 4 and moves along a circular locus as the rotor 3 rotates, and a circular locus that the crushing ring 5 moves downward. The crushing plate 6 is made to face the front side of the crushing object M to be crushed from above, and is compressed between the front side of the outer circular locus A of the crushing ring 5 and the crushing plate 6. The crushed object M is discharged from the hole 7a of the arc-shaped screen 7 disposed below the outer circular locus A of the crushing ring 5. On the outer peripheral surface of each crushing ring 5, a plurality of scalloped protrusions 5a are provided in a staggered manner.

前記破砕板6は、水平主軸2の略軸心の高さ位置よりも上方で、破砕リング5の外側円軌跡A側へオーバハング状に角度αだけ傾斜され、その下端とスクリーン7の前面側上端との間には、破砕板6と逆方向へ傾斜させた補助破砕板8が、破砕リング5の外側円軌跡Aと対向させて配設されている。なお、破砕板6は円弧状にオーバハングさせて傾斜させてもよい。   The crushing plate 6 is inclined at an angle α in an overhanging manner toward the outer circular locus A side of the crushing ring 5 above the height position of the substantially axial center of the horizontal main shaft 2. The auxiliary crushing plate 8 inclined in the opposite direction to the crushing plate 6 is disposed so as to face the outer circular locus A of the crushing ring 5. The crushing plate 6 may be inclined by overhanging in an arc shape.

前記円弧状のスクリーン7は、剛性のある厚板で形成されて、外側円軌跡Aとの間に隙間δを設けられており、この隙間δで被破砕物Mに圧縮力を作用させて、補助的な破砕板の役割もする。この実施形態では、隙間δは後述する板状被破砕物Mの厚み寸法tの2倍以内に設定されている。また、スクリーン7の後面側上端には、外側円軌跡Aに対向する固定板9が連設されている。   The arc-shaped screen 7 is formed of a rigid thick plate, and is provided with a gap δ between the outer circular locus A, and a compressive force is applied to the object M to be crushed in the gap δ. It also serves as an auxiliary crushing plate. In this embodiment, the gap δ is set within twice the thickness dimension t of the plate-shaped object M to be described later. Further, a fixed plate 9 facing the outer circular locus A is connected to the upper end of the rear side of the screen 7.

図3は、前記被破砕物Mが平坦で厚み寸法tを有する板状のもので、この板状被破砕物Mが2枚重なって破砕板6と破砕リング5の外側円軌跡Aとの間に噛み込まれることを想定したときの想定噛み込み角度βを模式的に示す。この実施形態では、この想定噛み込み角度βが18°となるように、破砕板6のオーバハング角度αが設定されている。このオーバハング角度αは、板状被破砕物Mの厚み寸法tに応じて可変とすることもできる。   FIG. 3 shows a plate-shaped object having a flat thickness M and the object M to be crushed, and the plate-shaped object M overlaps between the crushing plate 6 and the outer circular locus A of the crushing ring 5. An assumed biting angle β when it is assumed that the bite is bitten is schematically shown. In this embodiment, the overhang angle α of the crushing plate 6 is set so that the assumed biting angle β is 18 °. The overhang angle α can be made variable according to the thickness dimension t of the plate-shaped object M.

図4は、前記板状被破砕物Mが異なる材質層を有する複合材である場合の、破砕板6と破砕リング5間での破砕の状況を模式的に示す。この例は、複合材がJISA5350の強化プラスチック複合管を板状に切断したものであり、板状被破砕物Mの中心層が樹脂モルタルM1で、その両側の表面層が強化プラスチックM2で形成されている。   FIG. 4 schematically shows the state of crushing between the crushing plate 6 and the crushing ring 5 in the case where the plate-like object M is a composite material having different material layers. In this example, a reinforced plastic composite tube made of JISA5350 is cut into a plate shape, and the center layer of the plate-like material to be crushed M is made of resin mortar M1, and the surface layers on both sides thereof are made of reinforced plastic M2. ing.

前記破砕板6と破砕リング5間で圧縮力を付与される複合材の板状被破砕物Mは、破砕リング5の突起5aが接触する部位と接触しない部位との境界で剪断力も付与され、表面層の強化プラスチックM2に垂直なクラックが発生する。また、圧縮力が高くなる突起5aの接触部位では、中心層の樹脂モルタルM1にも多くのクラックが発生する。   The composite plate-like material to be crushed M to which a compressive force is applied between the crushing plate 6 and the crushing ring 5 is also provided with a shearing force at a boundary between a portion where the protrusion 5a of the crushing ring 5 is in contact with a portion where it is not in contact, A crack perpendicular to the reinforced plastic M2 of the surface layer is generated. Moreover, many cracks also generate | occur | produce in the resin mortar M1 of a center layer in the contact part of the processus | protrusion 5a from which a compressive force becomes high.

このように各クラックが発生した複合材の板状被破砕物Mは、破砕リング5の外側円軌跡Aとの間隔が狭くなる破砕板6の下部や補助破砕板8の部位で破砕されるとともに、樹脂モルタルM1と強化プラスチックM2が分離し、これらの分離破砕された樹脂モルタルM1や強化プラスチックM2がスクリーン7の孔7aから排出される。前述したように、スクリーン7と外側円軌跡Aとの隙間δは板状被破砕物Mの厚み寸法tの2倍以内に設定されているので、このスクリーン7との隙間δでも、樹脂モルタルM1と強化プラスチックM2は分離破砕される。   In this way, the plate-shaped object M of the composite material in which each crack is generated is crushed at the lower part of the crushing plate 6 where the distance from the outer circular locus A of the crushing ring 5 is narrow or at the site of the auxiliary crushing plate 8. The resin mortar M1 and the reinforced plastic M2 are separated, and the separated and crushed resin mortar M1 and the reinforced plastic M2 are discharged from the holes 7a of the screen 7. As described above, the gap δ between the screen 7 and the outer circular locus A is set within twice the thickness dimension t of the plate-like object M, so that the resin mortar M1 is used even with the gap δ between the screen 7 and the screen 7. The reinforced plastic M2 is separated and crushed.
