Description

本発明は、コンクリート廃材から得られるコンクリート塊を、圧縮力を加えながら互いに摩擦接触させて、その骨材からセメントモルタル分を除去するコンクリート塊摩砕装置に関する。   The present invention relates to a concrete lump grinding device for removing cement mortar from aggregates by bringing concrete lump obtained from concrete waste into frictional contact with each other while applying a compressive force.

コンクリート廃材は建設廃棄物の中で大きな割合を占めているが、これを破砕して得られるコンクリート塊は、吸水率の高いセメントモルタル分が多く付着しているため、そのままでは高い品質が求められる構造体コンクリート用骨材としては使用できず、再利用の用途が路盤材や埋め戻し材等に限られていた。   Concrete waste accounts for a large percentage of construction waste, but the concrete lump obtained by crushing it is adhering to a large amount of cement mortar with high water absorption, so high quality is required as it is. It could not be used as an aggregate for structural concrete, and its reuse was limited to roadbed materials and backfill materials.

そこで、コンクリート廃材から得られるコンクリート塊を、構造体コンクリート用骨材に再利用できるように、圧縮力を加えながら互いに摩擦接触させ（以下、この作用を「摩砕」という。）、その骨材からセメントモルタル分を除去するコンクリート塊摩砕装置が種々開発されてきた。例えば、特許文献１には、ケーシングの鉛直筒部内に設けた偏心回転軸に筒状ロータを回転自在に取り付けて、鉛直筒部と筒状ロータとの間に環状の摩砕室を形成し、この摩砕室の下方に摩砕室に充填されたコンクリート塊の排出を規制する排出量規制板を設けて、摩砕室に充填されるコンクリート塊を筒状ロータの偏心回転により摩砕する装置が記載されている。
特開２００３−２９９９７３号公報 Therefore, the concrete lump obtained from the waste concrete is brought into frictional contact with each other while applying a compressive force so that it can be reused as aggregate for structural concrete (hereinafter, this action is referred to as “grinding”). Various concrete agglomeration devices have been developed to remove cement mortar from slag. For example, in Patent Document 1, a cylindrical rotor is rotatably attached to an eccentric rotation shaft provided in a vertical cylindrical portion of a casing, and an annular grinding chamber is formed between the vertical cylindrical portion and the cylindrical rotor. An apparatus for grinding the concrete lump filled in the grinding chamber by eccentric rotation of the cylindrical rotor by providing a discharge amount regulating plate for regulating the discharge of the concrete lump filled in the grinding chamber below the grinding chamber. Is described.
JP 2003-299773 A

上記特許文献１に記載された摩砕装置では、排出量規制板を筒状ロータに取り付けて、筒状ロータの偏心回転で排出量規制板を常に揺さぶることにより、コンクリート塊の流動性を高め、摩砕室下端の排出口と排出量規制板との間が閉塞しないようにしている。また、この種の摩砕装置においてセメントモルタル分の除去率を高めるには、摩砕室におけるコンクリート塊の充填密度を高めて、コンクリート塊どうしを十分に摩擦接触させることが重要となるため、排出量規制板の外周縁に上方に突出する堰を設けることにより、排出量規制板上に滞留するコンクリート塊の量を増やして、摩砕室におけるコンクリート塊充填密度の向上を図っている。   In the grinding device described in the above-mentioned Patent Document 1, by attaching a discharge restriction plate to the cylindrical rotor and constantly shaking the discharge restriction plate by eccentric rotation of the cylindrical rotor, the fluidity of the concrete block is increased, The gap between the discharge port at the lower end of the grinding chamber and the discharge restriction plate is not blocked. Also, in order to increase the removal rate of cement mortar in this type of grinding equipment, it is important to increase the packing density of the concrete lumps in the grinding chamber and bring the concrete lumps into sufficient frictional contact. By providing a weir protruding upward on the outer peripheral edge of the amount regulating plate, the amount of the concrete block staying on the discharge amount regulating plate is increased, and the concrete block filling density in the grinding chamber is improved.

しかしながら、上記特許文献１の摩砕装置では、排出量規制板が筒状ロータの偏心回転によって揺さぶられるため、コンクリート塊の流動性が良すぎて、摩砕室排出口と排出量規制板との間が閉塞しにくいかわりに、期待されるように摩砕室のコンクリート塊充填密度を高めることができず、セメントモルタル分の除去率が必ずしも高くならない場合がある。これに対して、鉛直筒部の下端を排出量規制板に接近させたり堰を高いものと交換したりすれば、コンクリート塊の充填密度は高められるが、摩砕室排出口と排出量規制板との間が閉塞しやすくなり、運転状態が不安定になるおそれがある。   However, in the grinding device of the above-mentioned Patent Document 1, since the discharge restriction plate is shaken by the eccentric rotation of the cylindrical rotor, the fluidity of the concrete block is too good, and the grinding chamber discharge port and the discharge restriction plate are Instead of being difficult to block, the concrete lump filling density of the grinding chamber cannot be increased as expected, and the removal rate of cement mortar may not necessarily be high. On the other hand, if the lower end of the vertical cylinder is moved closer to the discharge restriction plate or the weir is replaced with a higher one, the packing density of the concrete block can be increased, but the grinding chamber outlet and the discharge restriction plate It is easy to block the gap between the two and the operation state may become unstable.

本発明の課題は、コンクリート塊の骨材からセメントモルタル分を効率よく除去でき、かつ常時安定した運転状態が得られるコンクリート塊摩砕装置を提供することである。   The subject of this invention is providing the concrete lump grinding apparatus which can remove a cement mortar part efficiently from the aggregate of a concrete lump, and can always obtain the stable driving | running state.

上記の課題を解決するために、本発明は、ケーシングの鉛直筒部内に設けた偏心回転軸に筒状ロータを回転自在に取り付けて、前記鉛直筒部と筒状ロータとの間に環状の摩砕室を形成し、この摩砕室の下方に摩砕室に充填されたコンクリート塊の排出を規制する排出量規制板を設けて、前記摩砕室に充填されるコンクリート塊を、前記筒状ロータの偏心回転により圧縮力を加えながら互いに摩擦接触させ、その骨材からセメントモルタル分を除去するコンクリート塊摩砕装置において、前記排出量規制板を前記筒状ロータに取り付け、この排出量規制板の外周縁に上方に突出する堰を設けて、その堰の高さを調節可能とした構成を採用した。   In order to solve the above problems, the present invention provides a cylindrical rotor rotatably attached to an eccentric rotating shaft provided in a vertical cylindrical portion of a casing, and an annular friction member between the vertical cylindrical portion and the cylindrical rotor. A crushing chamber is formed, and a discharge amount regulating plate for restricting discharge of the concrete lump filled in the crushing chamber is provided below the crushing chamber, and the concrete lump filled in the crushing chamber is formed into the cylindrical shape. In a concrete lump grinding apparatus that removes cement mortar from the aggregate by frictional contact with each other while applying a compression force by eccentric rotation of the rotor, the discharge amount restriction plate is attached to the cylindrical rotor, and this discharge amount restriction plate A configuration was adopted in which a weir that protrudes upward was provided on the outer peripheral edge, and the height of the weir could be adjusted.

すなわち、偏心回転する筒状ロータにコンクリート塊の摩砕室からの排出を規制する排出量規制板を取り付けることにより、コンクリート塊の流動性を高めて、摩砕室排出口と排出量規制板との間を閉塞しにくくするとともに、排出量規制板の外周縁に設けた堰の高さを摩砕処理されるコンクリート塊の粒度等の運転条件に応じて調節することにより、排出量規制板上のコンクリート塊滞留量を調整し、摩砕室のコンクリート塊充填密度を十分に高められるようにしたのである。   That is, by attaching a discharge restriction plate that regulates the discharge of the concrete lump from the grinding chamber to the cylindrical rotor that rotates eccentrically, the fluidity of the concrete lump is increased, and the grinding chamber discharge port, the discharge restriction plate, On the discharge restriction plate by adjusting the height of the weir provided on the outer periphery of the discharge restriction plate according to the operating conditions such as the particle size of the concrete lump to be ground. The concrete lump retention amount was adjusted so that the concrete lump filling density in the grinding chamber could be sufficiently increased.

また、前記ケーシングの鉛直筒部を昇降可能とすれば、鉛直筒部を堰の高さに応じて昇降させることにより、堰の高さによらずコンクリート塊の排出量規制板からの流出量を安定させて、コンクリート塊充填密度の向上と、摩砕室排出口と排出量規制板との間の閉塞の防止をより確実に両立することができる。   Further, if the vertical cylinder portion of the casing can be raised and lowered, the vertical cylinder portion is raised and lowered according to the height of the weir, so that the outflow amount from the concrete block discharge amount regulating plate can be reduced regardless of the height of the weir. It is possible to stabilize and improve both the concrete lump filling density and the prevention of clogging between the grinding chamber outlet and the discharge amount regulating plate more reliably.

本発明のコンクリート塊摩砕装置は、上述したように、偏心回転する筒状ロータに排出量規制板を取り付け、その外周縁に設けた堰の高さを調節可能としたものであるから、摩砕室排出口と排出量規制板との間が閉塞しにくく常時安定した運転状態が得られ、かつ摩砕室のコンクリート塊充填密度を十分に高めて、コンクリート塊の骨材からセメントモルタル分を効率よく除去することができる。   As described above, the concrete lump grinding device of the present invention is provided with a discharge amount regulating plate attached to an eccentric rotating cylindrical rotor, and the height of the weir provided on the outer periphery thereof can be adjusted. It is difficult to block between the crushing chamber outlet and the discharge restriction plate, and it is possible to obtain a stable operating condition at all times, and the concrete lump filling density of the crushing chamber is sufficiently increased so that the cement mortar content can be removed from the aggregate of the concrete lump. It can be removed efficiently.

以下、図面に基づき、本発明の実施形態を説明する。このコンクリート塊摩砕装置は、図１に示すように、ケーシング１の上部が別体の鉛直筒部材２で形成され、ケーシング１の中心に設けられた回転軸３の上部が偏心軸部３ａとされて鉛直筒部材２に挿入され、この偏心軸部３ａに筒状ロータ４が軸受５で回転自在に取り付けられて、鉛直筒部材２と筒状ロータ４との間に環状の摩砕室６が形成されている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the concrete lump grinding apparatus has an upper portion of the casing 1 formed by a separate vertical cylindrical member 2, and an upper portion of the rotating shaft 3 provided at the center of the casing 1 is formed with an eccentric shaft portion 3 a. Is inserted into the vertical cylindrical member 2, and the cylindrical rotor 4 is rotatably attached to the eccentric shaft portion 3 a by a bearing 5. An annular grinding chamber 6 is interposed between the vertical cylindrical member 2 and the cylindrical rotor 4. Is formed.

摩砕処理されるコンクリート塊は、鉛直筒部材２の上方から投入され、摩砕室６に充填される。環状の摩砕室６の内周壁を形成する筒状ロータ４は、内ロータ４ａとライナを兼ねた外ロータ４ｂとからなり、内ロータ４ａの下端外周側に、摩砕室６に充填されたコンクリート塊の排出を規制する排出量規制板７が取り付けられている。なお、筒状ロータ４の下部に外側への傾斜面を設けたのは、摩砕室６に充填されるコンクリート塊の落下を抑制するためである。   The concrete block to be ground is fed from above the vertical cylindrical member 2 and filled in the grinding chamber 6. The cylindrical rotor 4 that forms the inner peripheral wall of the annular grinding chamber 6 is composed of an inner rotor 4a and an outer rotor 4b that also serves as a liner. The grinding chamber 6 is filled on the outer peripheral side of the lower end of the inner rotor 4a. A discharge amount restriction plate 7 for restricting the discharge of the concrete block is attached. The reason why the inclined surface to the outside is provided at the lower part of the cylindrical rotor 4 is to suppress the fall of the concrete block filled in the grinding chamber 6.

図２に示すように、前記排出量規制板７は、内ロータ４ａ外周に嵌め込まれる内板７ａと、内板７ａにボルト止めされる外板７ｂとからなり、外板７ｂの外周縁に上方に突出する堰８が設けられている。この堰８は、その下端部内周に形成された環状突部８ａが筒状のスペーサ９を介して排出量規制板７の外板７ｂにボルト止めされており、スペーサ９の長さを変えることにより高さを調節して排出量規制板７上のコンクリート塊Ａの滞留量を調整できるようになっている。   As shown in FIG. 2, the discharge amount restricting plate 7 includes an inner plate 7a fitted on the outer periphery of the inner rotor 4a and an outer plate 7b bolted to the inner plate 7a. A weir 8 is provided to project. The weir 8 has an annular protrusion 8 a formed on the inner periphery of the lower end thereof, which is bolted to the outer plate 7 b of the discharge restriction plate 7 via a cylindrical spacer 9, and the length of the spacer 9 is changed. Thus, the amount of staying of the concrete block A on the discharge restriction plate 7 can be adjusted by adjusting the height.

前記回転軸３は、ケーシング１の内側に張り出す支持部１０に軸受１１で回転自在に支持され、その下端に取り付けられたプーリ１２に、Ｖベルト１３を介してモータ１４の回転力が伝達されるようになっている。   The rotary shaft 3 is rotatably supported by a bearing 11 on a support portion 10 projecting inside the casing 1, and the rotational force of a motor 14 is transmitted to a pulley 12 attached to the lower end of the rotary shaft 3 via a V belt 13. It has become so.

前記鉛直筒部材２は、油圧シリンダ１５で昇降可能とされており、図２に示すように、その下端外周縁と堰８の上端内周縁の間の距離（Ｌ）、すなわち排出量規制板７から流出するコンクリート塊Ａの通路の幅を調節できるようになっている。また、万が一、摩砕室６排出口と排出量規制板７との間が閉塞されても、鉛直筒部材２を上昇させるのみで、摩砕装置の運転を停止することなく閉塞を解消することもできる。   The vertical cylinder member 2 can be moved up and down by a hydraulic cylinder 15. As shown in FIG. 2, the distance (L) between the outer peripheral edge at the lower end and the inner peripheral edge at the upper end of the weir 8, that is, the discharge amount regulating plate 7. The width of the passage of the concrete block A flowing out from the wall can be adjusted. Moreover, even if the gap between the grinding chamber 6 outlet and the discharge amount restricting plate 7 is blocked, the vertical cylinder member 2 is merely lifted, and the blockage is eliminated without stopping the operation of the grinding device. You can also.

次に、この摩砕装置の摩砕作用について説明する。前記筒状ロータ４は回転軸３の回転に伴って偏心回転するので、環状の摩砕室６の半径方向間隙は各周方向位置で連続的に拡縮する。従って、この拡縮する間隙に充填されたコンクリート塊は、圧縮力を受けながら互いに摩擦接触し、その骨材からセメントモルタル分が除去される。なお、このとき、筒状ロータ４はコンクリート塊でその回転を規制されるので、コンクリート塊の流動に伴って回転軸３の回転方向と逆方向に低速で回転する。   Next, the grinding action of this grinding device will be described. Since the cylindrical rotor 4 rotates eccentrically with the rotation of the rotary shaft 3, the radial gap of the annular grinding chamber 6 continuously expands and contracts at each circumferential position. Accordingly, the concrete blocks filled in the expanding and contracting gaps are brought into frictional contact with each other while receiving a compressive force, and the cement mortar is removed from the aggregate. At this time, since the rotation of the cylindrical rotor 4 is restricted by the concrete block, the cylindrical rotor 4 rotates at a low speed in the direction opposite to the rotation direction of the rotary shaft 3 with the flow of the concrete block.

上記摩砕室６での摩砕により分離された骨材とセメントモルタル分は、排出量規制板７上で一旦滞留した後、堰８を乗り越えて排出コンベヤ１６上に落下し、排出コンベヤ１６で図示省略した振動篩や風篩に送られて篩い分けられる。   Aggregate and cement mortar separated by grinding in the grinding chamber 6 once stays on the discharge amount regulating plate 7, then passes over the weir 8 and falls onto the discharge conveyor 16. It is sent to a vibrating sieve or wind sieve (not shown) and sieved.

このコンクリート塊摩砕装置は、上記の構成であり、前述の従来装置と同様、偏心回転する筒状ロータ４に排出量規制板７を取り付けており、排出量規制板７の揺さぶりで摩砕室６に充填されたコンクリート塊の流動性が高められるので、摩砕室６排出口と排出量規制板７との間が閉塞しにくい。しかも、排出量規制板７の外周縁に設けた堰８の高さが調節可能となっているので、堰８の高さをコンクリート塊の粒度等の運転条件に応じて調節することにより、排出量規制板７上のコンクリート塊の滞留量を調整し、摩砕室６のコンクリート塊充填密度を高めて、コンクリート塊の骨材からセメントモルタル分を効率よく除去することができる。   This concrete lump grinding device has the above-described configuration, and like the above-described conventional device, the discharge amount restriction plate 7 is attached to the cylindrical rotor 4 that rotates eccentrically, and the grinding chamber is shaken by the shake of the discharge amount restriction plate 7. Since the fluidity of the concrete block filled in 6 is enhanced, it is difficult to block between the grinding chamber 6 outlet and the discharge amount regulating plate 7. Moreover, since the height of the weir 8 provided on the outer peripheral edge of the discharge amount regulating plate 7 can be adjusted, the height of the weir 8 can be adjusted according to the operating conditions such as the particle size of the concrete lump. It is possible to efficiently remove the cement mortar from the aggregate of the concrete lump by adjusting the residence amount of the concrete lump on the amount regulating plate 7 and increasing the concrete lump filling density of the grinding chamber 6.

さらに、鉛直筒部材２が昇降可能となっているので、運転状態によって堰８の高さを変えたときも、これに応じて鉛直筒部材２を昇降させることにより、コンクリート塊の排出量規制板７からの流出量が大きく変化しないようにして、摩砕室６排出口と排出量規制板７との間の閉塞の防止とコンクリート塊充填密度の向上を両立することができる。   Furthermore, since the vertical cylinder member 2 can be moved up and down, even when the height of the weir 8 is changed depending on the operating state, the vertical cylinder member 2 is moved up and down in accordance with this, thereby restricting the discharge amount of the concrete lump. 7 so that the amount of outflow from 7 does not change significantly, and it is possible to achieve both prevention of blockage between the grinding chamber 6 outlet and the discharge amount regulating plate 7 and improvement of the concrete lump filling density.

すなわち、図３に示すように、図２の状態から堰８を高くしてコンクリート塊の充填密度をさらに高めようとするときは、堰８の高さ変更分とほぼ同じ高さだけ鉛直筒部材２を上昇させる。このようにすれば、鉛直筒部材２下端外周縁と堰８上端内周縁の間の距離（Ｌ’）が図２の場合（Ｌ）とほぼ同じになるので、堰８を高くしてもコンクリート塊の排出量規制板７からの流出量が大きく減少することはなく、摩砕室６排出口と排出量規制板７との間が閉塞しにくい状態を保持することができる。一方、図４に示すように、堰８を低くして図２の状態よりもスムーズにコンクリート塊を流動させようとするときには、堰８の高さ変更分とほぼ同じ高さだけ鉛直筒部材２を下降させればよい。これにより、鉛直筒部材２下端外周縁と堰８上端内周縁の間の距離（Ｌ”）が図２の場合（Ｌ）とほぼ同じになり、堰８を低くしてもコンクリート塊の排出量規制板７からの流出量の増加を抑えられるので、摩砕室６のコンクリート塊充填密度が高い状態を保持することができる。   That is, as shown in FIG. 3, when the weir 8 is raised from the state of FIG. 2 to further increase the packing density of the concrete block, the vertical cylinder member is almost the same height as the height change of the weir 8 Raise 2 In this case, the distance (L ′) between the outer peripheral edge at the lower end of the vertical cylindrical member 2 and the inner peripheral edge at the upper end of the weir 8 is substantially the same as in FIG. 2 (L). The outflow amount of the lump discharge amount regulating plate 7 is not greatly reduced, and the state in which the gap between the grinding chamber 6 discharge port and the discharge amount regulating plate 7 is hardly blocked can be maintained. On the other hand, as shown in FIG. 4, when the weir 8 is lowered to make the concrete block flow more smoothly than in the state of FIG. 2, the vertical cylinder member 2 is almost the same height as the height change of the weir 8. Should be lowered. As a result, the distance (L ") between the outer peripheral edge at the lower end of the vertical cylindrical member 2 and the inner peripheral edge at the upper end of the weir 8 is substantially the same as in FIG. 2 (L). Since the increase in the amount of outflow from the regulating plate 7 can be suppressed, the state where the concrete block filling density of the grinding chamber 6 is high can be maintained.

なお、上述した実施形態では、堰８の環状突部８ａと排出量規制板７の外板７ｂとの間に挟まれるスペーサ９の長さを変えて堰８の高さを調節するようにしたが、スペーサ９に代えて油圧シリンダやエアシリンダ等を用いて堰を昇降させるようにしてもよい。   In the embodiment described above, the height of the weir 8 is adjusted by changing the length of the spacer 9 sandwiched between the annular protrusion 8a of the weir 8 and the outer plate 7b of the discharge amount regulating plate 7. However, the weir may be moved up and down using a hydraulic cylinder, an air cylinder or the like instead of the spacer 9.
