Description

本発明は、道路工事などによって掘り起こされるアスファルト舗装廃材から骨材を分離回収して再生する装置に関する。   The present invention relates to an apparatus for separating and recovering aggregate from asphalt pavement waste material dug up by road construction or the like.

近年、アスファルトプラントにて製造されるアスファルト混合物は、その使用用途に応じて特殊なものが製造される場合が増えており、例えば５〜１３ｍｍ粒径の骨材（約８５重量％）と砂（約１５重量％）の二種類の骨材を専ら使用し、舗装道路の表面に雨水などが溜まらないように舗装道路に水が染み込んでいくと同時に染み込んだ水を下方の路床から排水させる、いわゆる排水性アスファルト混合物も多く製造されている。   In recent years, asphalt mixtures produced in an asphalt plant have been increasingly produced specially depending on the intended use. For example, aggregate (about 85% by weight) of 5-13 mm particle size and sand ( Using only two types of aggregates (about 15% by weight), water soaks into the paved road so that rainwater does not collect on the surface of the paved road, and drains the soaked water from the lower roadbed. Many so-called drainage asphalt mixtures are also produced.

そして、この排水性アスファルト混合物による舗装道路を掘り起こした際に生じるアスファルト舗装廃材（以下「排水性廃材」という）を再生する場合、通常の廃材を再生する場合と同様にクラッシャーなどで破砕処理すると、５〜１３ｍｍ粒径の骨材が細かく破砕されてしまい、その結果、細かい粒度のものが、例えば、１５重量％であったものが４０重量％となるなど多く発生し、これら細かい粒度のものをどう使用していくかの問題が発生している。   And, when reclaiming asphalt pavement waste material (hereinafter referred to as “drainage waste material”) generated when digging up a pavement road with this drainage asphalt mixture, crushing with a crusher etc. as in the case of regenerating normal waste material, As a result, aggregates having a particle size of 5 to 13 mm are finely crushed, and as a result, fine particles having a fine particle size, for example, 15% by weight and 40% by weight are often generated. There is a problem of how to use it.

このような問題に対して、排水性廃材に温水や高温の水蒸気を浴びせるなどして温浴させ、排水性廃材中のアスファルト分を軟化溶融させて解砕することにより、廃材中の骨材を分離回収するようにした方法がある。（特許文献１、２参照）。これらの方法によれば、排水性廃材中の骨材が細かく破砕されてしまうことはない。
実公昭５９−１７９２５号 特開昭５５−３６５１４号 In response to such problems, the aggregate in the waste material is separated by allowing the waste water waste to be warmed by warm water or high temperature steam, etc., and softening and melting the asphalt content in the waste water waste. There is a method to collect. (See Patent Documents 1 and 2). According to these methods, the aggregate in the drainage waste material is not crushed finely.
Actual Kosho 59-17925 JP 55-36514

しかしながら、上記のような温浴解砕処理は、クラッシャーによる破砕処理などと比較して処理能力の点で大きく劣る上、おおまかに粗破砕はできるが、骨材粒度単位に十分細かく破砕できず、排水性廃材であれば回収した骨材の粒度構成がそのまま排水性アスファルト混合物の製造時の骨材粒度構成近くになっていないと考えられる。   However, the warm bath crushing treatment as described above is greatly inferior in terms of processing capacity compared to crushing treatment with a crusher, etc., and roughly rough crushing is possible, but it cannot be crushed sufficiently finely into aggregate particle size units, It is considered that the aggregate particle size of the recovered aggregate is not close to the aggregate particle size configuration at the time of producing the drainable asphalt mixture.

本発明は上記の点に鑑み、排水性廃材などの廃材の塊を効率良く解砕し、かつ廃材中の骨材を再利用可能な状態で回収するアスファルト舗装廃材の再生装置を提供することを課題とする。   In view of the above points, the present invention provides an asphalt pavement waste material recycling device that efficiently disintegrates a lump of waste material such as drainage waste material and collects aggregate in the waste material in a reusable state. Let it be an issue.

上記の課題を解決するために、請求項１記載のアスファルト舗装廃材の再生装置は、アスファルト舗装廃材に温水や高温の水蒸気を浴びせて廃材中のアスファルト分を軟化溶融させて粗解砕する温浴解砕手段と、該温浴解砕手段にて粗解砕した廃材を粒度選別するスクリーンと、該スクリーンを通過する所定粒度以下の廃材を強制撹拌させて細解砕することで骨材を分離回収する解砕ミキサとを備えたことを特徴としている。   In order to solve the above-mentioned problems, the asphalt pavement waste recycling apparatus according to claim 1 is a hot bath solution in which asphalt pavement waste is exposed to hot water or high-temperature steam to soften and melt the asphalt content in the waste to coarsely crush. The aggregate is separated and recovered by crushing means, a screen for selecting the particle size of the waste material roughly crushed by the warm bath crushing means, and forcibly agitating the waste material having a predetermined particle size or less that passes through the screen. It features a crushing mixer.

また、請求項２記載のアスファルト舗装廃材の再生装置は、前記解砕ミキサは、一端側に投入口を、他端側に排出口を備えた撹拌槽に二本の平行な撹拌軸をそれぞれ相反方向へ回転自在に備え、該撹拌軸の軸周りには略棒状の複数の撹拌部材を等角度間隔に、かつ軸方向へは螺旋状の配置となるように所定角度ずつずらしながら所定間隔にて突設すると共に、一方の撹拌軸の撹拌部材が隣り合う他方の撹拌軸の撹拌部材間の隙間と噛み合うように位相をずらし、廃材を回転する双方の撹拌軸の撹拌部材同士で突き潰しながら細解砕するように構成して成ることを特徴としている。   According to a second aspect of the present invention, there is provided a reclaiming apparatus for asphalt pavement waste material, wherein the crushing mixer has two parallel stirring shafts in a stirring tank provided with an input port on one end side and a discharge port on the other end side. A plurality of substantially rod-shaped stirring members are arranged at equal angular intervals around the axis of the agitation shaft, and at predetermined intervals while being shifted by a predetermined angle so as to be spirally arranged in the axial direction. While projecting, the phase is shifted so that the stirring member of one stirring shaft engages with the gap between the stirring members of the other adjacent stirring shaft, and the waste material is crushed between the stirring members of both stirring shafts rotating. It is characterized by being configured to break up.

以上のように本発明に係る請求項１記載のアスファルト舗装廃材の再生装置によれば、アスファルト舗装廃材に温水や高温の水蒸気を浴びせて廃材中のアスファルト分を軟化溶融させて粗解砕する温浴解砕手段と、該温浴解砕手段にて粗解砕した廃材を粒度選別するスクリーンと、該スクリーンを通過する所定粒度以下の廃材を強制撹拌させて細解砕することで骨材を分離回収する解砕ミキサとを備えたので、温浴解砕によって廃材中のアスファルト分の結合力を弱めて粗破砕した上で、解砕ミキサにて効率良く、かつ確実に細解砕処理することができ、骨材をそのまま再利用可能な状態で分離回収することができる。   As described above, according to the asphalt pavement waste recycling apparatus according to claim 1 of the present invention, the asphalt pavement waste material is exposed to warm water or high-temperature steam to soften and melt the asphalt component in the waste material to roughly disintegrate. The aggregate is separated and recovered by pulverizing means, a screen for selecting the particle size of the waste material roughly crushed by the warm bath pulverizing means, and forcibly agitating the waste material having a predetermined particle size or less that passes through the screen. Since the crushing mixer is equipped with a crushing mixer, the asphalt content in the waste material is weakened and coarsely crushed by hot bath crushing. The aggregate can be separated and recovered in a state where it can be reused as it is.

また、請求項２記載のアスファルト舗装廃材の再生装置によれば、前記解砕ミキサは、一端側に投入口を、他端側に排出口を備えた撹拌槽に二本の平行な撹拌軸をそれぞれ相反方向へ回転自在に備え、該撹拌軸の軸周りには略棒状の複数の撹拌部材を等角度間隔に、かつ軸方向へは螺旋状の配置となるように所定角度ずつずらしながら所定間隔にて突設すると共に、一方の撹拌軸の撹拌部材が隣り合う他方の撹拌軸の撹拌部材間の隙間と噛み合うように位相をずらし、廃材を回転する双方の撹拌軸の撹拌部材同士で突き潰しながら細解砕するように構成して成るので、廃材を未解砕のまま送り出してしまうおそれもなく、効率良く、かつ確実に細解砕処理することができる。   Moreover, according to the asphalt pavement waste recycling apparatus according to claim 2, the crushing mixer has two parallel stirring shafts in a stirring tank provided with an input port on one end side and a discharge port on the other end side. A plurality of substantially rod-shaped agitating members are provided around the agitation shaft so as to be rotatable in opposite directions, and are spaced at regular intervals while being shifted by a prescribed angle so as to be arranged in a spiral manner in the axial direction. The stirrer of one stirring shaft is shifted in phase so that the stirrer of one stirrer shaft is engaged with the gap between the stirrer members of the other adjacent stirrer shaft, and the stirrers of both stirring shafts rotating the waste material are crushed together However, since the waste material is configured to be pulverized, the waste material can be efficiently and reliably pulverized without fear that the waste material is sent out without being crushed.

本発明に係わる請求項１記載のアスファルト舗装廃材の再生装置にあっては、道路工事などに伴って生じるアスファルト舗装廃材を温水や高温の水蒸気にて温浴させるための貯留ホッパを備え、該貯留ホッパ内には温浴によって粗解砕を終えた廃材を順次送り出すためのスクリュフィーダを備える。また、前記スクリュフィーダの送り出し先側には温浴解砕した廃材を粒度選別し、解砕が不十分な廃材を取り除くためのスクリーンを配設していると共に、該スクリーンの下位にはスクリーンを通過する所定粒度以下にまで粗解砕した廃材を強制撹拌させて細解砕し、廃材から骨材を分離回収していく解砕ミキサを配設する。   The reclaiming device for asphalt pavement waste according to claim 1 according to the present invention comprises a storage hopper for warming the asphalt pavement waste generated during road construction with warm water or high-temperature steam. Inside, there is a screw feeder for sending out the waste material that has been roughly crushed by a warm bath. In addition, a screen is provided on the delivery destination side of the screw feeder to screen the waste material crushed in the hot bath and remove the waste material that is not sufficiently crushed, and the screen passes below the screen. A crushing mixer is provided in which the waste material roughly crushed to a predetermined particle size or less is forcibly agitated and finely crushed, and the aggregate is separated and recovered from the waste material.

そして、廃材を解砕して骨材を分離回収するときには、先ず、廃材を貯留ホッパへ投入し、そこへ温水、或いは高温の水蒸気を浴びせて廃材を温浴させる。すると、廃材中のアスファルト分が軟化溶融していき、廃材は次第にばらばらに解砕していく。こうして、粗解砕した廃材をスクリュフィーダにてホッパ外へと順次送り出し、スクリーン上へ払い出していく。スクリーンでは払い出された廃材を粒度選別し、スクリーンを通過しない解砕の不十分な廃材は貯留ホッパへ送り返して再度温浴させる一方、スクリーンを通過する程度にまで解砕した廃材はそのまま解砕ミキサへ投入する。そして、解砕ミキサでは温浴解砕処理によって廃材中のアスファルト分の結合力を弱めて粗解砕したものを強制撹拌して、効率良く、かつ確実に細解砕処理していく。このようにして、細解砕処理を終えると、骨材を有効な状態で、特に排水性廃材であれば元の粒度と変わらない状態で分離回収でき、そのまま排水性アスファルト混合物の製造に再利用可能となって好適である。   When the waste material is crushed and the aggregate is separated and recovered, first, the waste material is put into a storage hopper, and hot water or high-temperature steam is bathed therein to bathe the waste material. Then, the asphalt content in the waste material is softened and melted, and the waste material is gradually broken apart. In this way, the roughly crushed waste material is sequentially sent out of the hopper by a screw feeder and delivered onto the screen. The screen sorts out the waste material that has been dispensed, and sends the waste material that does not pass through the screen back to the storage hopper and warms it again, while the waste material that has been shattered to the extent that it passes through the screen remains as it is. To input. The crushing mixer forcibly stirs the coarsely crushed material by weakening the binding strength of the asphalt component in the waste material by the hot bath crushing process, and efficiently and reliably performs the crushing process. In this way, after the comminution treatment is completed, the aggregate can be separated and recovered in an effective state, particularly in the case of drainage waste, in the same state as the original particle size, and reused as it is for the production of drainage asphalt mixture. It is possible and preferable.

また、請求項２記載のアスファルト舗装廃材の再生装置にあっては、解砕処理に用いる解砕ミキサは、撹拌槽に備えた二本の撹拌軸の軸周りには略棒状の複数の撹拌部材を等角度間隔に、かつ軸方向へは螺旋状の配置となるように所定角度ずつずらしながら所定間隔にて突設すると共に、一方の撹拌軸の撹拌部材が隣り合う他方の撹拌軸の撹拌部材間の隙間と丁度噛み合うように位相をずらし、撹拌槽に投入した廃材を回転する双方の撹拌軸の撹拌部材同士で突き潰しながら細解砕するように構成する。   Moreover, in the asphalt pavement waste recycling apparatus according to claim 2, the crushing mixer used for the crushing process includes a plurality of substantially rod-shaped stirring members around the two stirring shafts provided in the stirring tank. Are projected at predetermined intervals while being shifted by a predetermined angle so as to form a spiral arrangement in the axial direction, and the stirring member of one stirring shaft is adjacent to the stirring member of the other stirring shaft The phase is shifted so as to mesh with the gap between them, and the waste material thrown into the stirring tank is configured to be crushed while being crushed by the stirring members of both rotating stirring shafts.

そして、廃材を解砕して廃材から骨材を分離回収するときには、温浴解砕処理にて廃材中のアスファルト分の結合力を弱めて粗解砕したものを前記解砕ミキサへ投入する。すると、解砕ミキサでは、一方の撹拌軸の撹拌部材間の隙間に嵌り込んで撹拌軸の回転と共に回転する廃材に対し、隣り合う他方の撹拌軸の撹拌部材先端部が撹拌軸の回転と共にその廃材へ突き刺さっていく。このとき、廃材はその上下部分をそれぞれ撹拌部材にて支持された状態となっているため、他方の撹拌軸の撹拌部材先端部が突き刺さっていっても逃げることなく、そのまま突き潰されていく。そして、廃材はこのような突き潰しを何度も繰り返し受ける内に次第に細解砕されていく。   Then, when the waste material is crushed and the aggregate is separated and recovered from the waste material, the coarsely pulverized product obtained by weakening the binding force of the asphalt in the waste material in the hot bath pulverization treatment is put into the pulverization mixer. Then, in the crushing mixer, with respect to the waste material that fits into the gap between the stirring members of one stirring shaft and rotates with the rotation of the stirring shaft, the tip of the stirring member of the other adjacent stirring shaft moves with the rotation of the stirring shaft. Pierce into the scrap. At this time, since the upper and lower portions of the waste material are supported by the stirring member, even if the tip of the stirring member of the other stirring shaft is stuck, it is crushed as it is without escaping. The waste material is gradually shattered while receiving such crushing over and over again.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図中の１は所定温度の温水に排水性廃材などのアスファルト舗装廃材を浸して温浴させることにより、廃材中のアスファルト分を軟化溶融させてその結合力を弱めてばらばらに粗解砕させる温浴解砕手段である温浴解砕機であって、廃材を温水に浸しながら貯留可能とする貯留ホッパ２を備え、該貯留ホッパ２の上流側の上位には廃材を貯留ホッパ２内へ投入するベルトコンベヤ３を備える一方、貯留ホッパ２の内部には粗解砕処理を終えた廃材を順次外部へと送り出すスクリュフィーダ４を備えており、廃材の連続的な解砕処理を可能としている。なお、このような連続式でなく、バッチ式に解砕処理するようにしても良い。   In the figure, 1 is a warm bath solution in which asphalt pavement waste materials such as drainage waste materials are immersed in warm water at a predetermined temperature to soften and melt the asphalt content in the waste materials and weaken the bond strength to loosely break apart. A warm bath crusher, which is a crushing means, includes a storage hopper 2 that can store waste material while immersing the waste material in warm water, and a belt conveyor 3 that puts the waste material into the storage hopper 2 on the upstream side of the storage hopper 2 On the other hand, the storage hopper 2 is provided with a screw feeder 4 that sequentially feeds the waste material that has been subjected to the rough crushing process to the outside, thereby enabling continuous crushing process of the waste material. In addition, you may make it grind | pulverize in a batch type instead of such a continuous type.

前記温浴解砕機１の下流側にはスクリーン５を配設しており、該スクリーン５にて解砕の不十分なオーバーサイズの廃材を取り除くようにしている。なお、このようなオーバーサイズの廃材は、別途備えたコンベヤなどで直ちに温浴解砕機１へと戻して再度解砕処理させるようにすると好ましい。   A screen 5 is disposed on the downstream side of the warm bath pulverizer 1, and the screen 5 removes oversized waste material that is insufficiently crushed. In addition, it is preferable that such oversized waste material is immediately returned to the hot bath crusher 1 by a conveyor or the like separately provided and crushed again.

前記スクリーン５の下位にはスクリーン５を通過する所定粒度以下にまで粗解砕した廃材を強制撹拌させることで細解砕する解砕ミキサを６を配設している。前記解砕ミキサ６は、撹拌槽７に二本の平行な撹拌軸８、８´を貫通し、撹拌槽７を搭載する基台９に固定した軸受１０により回転自在に支持している。   Below the screen 5, a pulverizing mixer 6 is disposed for finely pulverizing the waste material coarsely pulverized to a predetermined particle size or less passing through the screen 5. The crushing mixer 6 passes through two parallel stirring shafts 8 and 8 ′ in the stirring tank 7 and is rotatably supported by a bearing 10 fixed to a base 9 on which the stirring tank 7 is mounted.

撹拌軸８、８´の一端部には減速機１１、１１´を介して駆動用モータ１２、１２´を取り付け、駆動用モータ１２、１２´の駆動によって撹拌軸８、８´をそれぞれ相反方向へ回転可能にしている。なお、駆動用モータ１２、１２´にインバータを取付けて撹拌軸８、８´の回転数を廃材の性状に応じて自在に変更できるようにしておいても良い。また、撹拌軸８、８´の他端部には撹拌軸８、８´を互いに同期速度で回転させるためにギヤ１３、１３´を装着している。   Driving motors 12 and 12 'are attached to one end portions of the stirring shafts 8 and 8' via speed reducers 11 and 11 ', and the stirring shafts 8 and 8' are driven in opposite directions by driving the driving motors 12 and 12 ', respectively. It can be rotated to. Note that an inverter may be attached to the drive motors 12 and 12 'so that the rotation speed of the stirring shafts 8 and 8' can be freely changed according to the properties of the waste material. In addition, gears 13 and 13 'are attached to the other ends of the stirring shafts 8 and 8' in order to rotate the stirring shafts 8 and 8 'at a synchronous speed.

撹拌軸８、８´の表面には廃材を撹拌するための撹拌部材１４を多数備えている。前記撹拌部材１４は、断面略六角形で所定長さの棒状の部材であり、この撹拌部材１４を撹拌軸８、８´の軸回りに等角度間隔に、図示例では９０度間隔にて四本突設し、かつ軸方向へは螺旋状の配置となるように所定角度ずつずらしながら、図示例では４５度ずつずらしながら所定間隔にて突設しており、こうすることによって撹拌部材１４を四条の螺旋状の配置とし、この螺旋状配置の撹拌部材１４のスクリュー作用によって材料を下流方向へ移動させるようにしている。   A large number of stirring members 14 for stirring the waste material are provided on the surfaces of the stirring shafts 8 and 8 '. The stirring member 14 is a rod-shaped member having a substantially hexagonal cross section and a predetermined length. The stirring member 14 is equiangularly spaced around the shafts of the stirring shafts 8 and 8 ', and in the illustrated example, at four intervals of 90 degrees. In this example, the protrusions are provided at predetermined intervals while being shifted by a predetermined angle so as to be arranged in a spiral shape in the axial direction. In the illustrated example, the protrusions are protruded at predetermined intervals while being shifted by 45 degrees. The spiral arrangement of the four strips is used, and the material is moved in the downstream direction by the screw action of the stirring member 14 having the spiral arrangement.

また、一方の撹拌軸８、８´の撹拌部材１４が隣り合う他方の撹拌軸８、８´の撹拌部材１４間の隙間と丁度噛み合うように位相をずらし、図示例では４５度ずらし、図５に示すように、撹拌槽７に投入した廃材Ｒを回転する双方の撹拌軸８、８´の撹拌部材１４同士で突き潰しながら細解砕していく構成としている。   Further, the phase is shifted so that the stirring member 14 of one stirring shaft 8, 8 ′ just meshes with the gap between the stirring members 14 of the other stirring shaft 8, 8 ′, and in the example shown in FIG. As shown in FIG. 3, the waste material R introduced into the stirring tank 7 is crushed while being crushed by the stirring members 14 of both rotating stirring shafts 8 and 8 '.

１５は材料を投入する投入口であって、撹拌槽７の駆動用モータ１２、１２´側の上部に配設している。２１は材料を排出する排出口であって、撹拌槽７の駆動用モータ１２、１２´側と反対側の下部に配設しており、投入口１５より投入した材料を撹拌槽７内に所定時間滞留させた後、排出口１６から排出するようにしている。   Reference numeral 15 denotes an input port for supplying a material, which is disposed at the upper part of the stirring tank 7 on the side of the drive motors 12 and 12 ′. Reference numeral 21 denotes a discharge port for discharging the material, which is disposed in the lower part of the stirring tank 7 on the side opposite to the drive motors 12 and 12 ′ side. After being held for a period of time, it is discharged from the discharge port 16.

しかして、上記のアスファルト舗装廃材の再生装置にて、道路工事などに伴って発生した排水性廃材などの廃材を解砕処理して骨材を分離回収するときには、先ず、廃材をベルトコンベヤ３にて温浴解砕機１の貯留ホッパ２内へ順次投入すると共に、そこへ温水を投入して廃材を温浴させる。すると、廃材中のアスファルト分が温度上昇していくにつれて軟化溶融していき、廃材は次第にばらばらに解砕していく。続いて、こうしてある程度粗解砕した廃材をスクリュフィーダ４にて貯留ホッパ２外部へと順次送り出し、スクリーン５上へ払い出していく。そして、スクリーン５では払い出された廃材を篩い分けて粒度選別し、スクリーン５を通過しない解砕の不十分な廃材は別途用意したベルトコンベヤなどで貯留ホッパ２へと送り返して再度温浴解砕処理する一方、スクリーン５を通過可能な程度にまで解砕した廃材はそのままスクリーン５下位の解砕ミキサ６へ投入していく。   Therefore, when the above asphalt pavement waste recycling apparatus is used to disintegrate waste materials such as drainage waste materials generated during road construction and separate and recover aggregates, first, the waste materials are transferred to the belt conveyor 3. Then, the hot water is pulverized sequentially into the storage hopper 2 of the hot bath crusher 1, and warm water is poured into the hot water pulverizer 1 to warm the waste material. Then, the asphalt content in the waste material softens and melts as the temperature rises, and the waste material gradually breaks apart. Subsequently, the waste material that has been roughly crushed to some extent in this way is sequentially sent out to the outside of the storage hopper 2 by the screw feeder 4 and is discharged onto the screen 5. The screen 5 screens out the waste material that has been dispensed, selects the particle size, and sends the waste material that does not pass through the screen 5 to the storage hopper 2 using a belt conveyor or the like that is separately prepared, and then pulverizes again in the warm bath. On the other hand, the waste material crushed to such an extent that it can pass through the screen 5 is fed as it is to the crushing mixer 6 below the screen 5.

そして、解砕ミキサ６では先に行った温浴解砕処理によって廃材中のアスファルト分の結合力を十分に弱めたものを、螺旋状の配置とした撹拌部材１４によって下流側へ順次送り出していきながら強制撹拌する。すると、図５に示すように、一方の撹拌軸８、８´の撹拌部材１４間の隙間部分に嵌り込むようにして撹拌軸８、８´の回転と共に回転する廃材Ｒに対し、隣り合う他方の撹拌軸８、８´の撹拌部材１４の先端部が撹拌軸８、８´の回転と共にその廃材Ｒへと突き刺さっていく。このとき、廃材Ｒはその上下部分をそれぞれ撹拌部材１４にて支持された状態となっているため、他方の撹拌軸８、８´の撹拌部材１４の先端部が突き刺さっていっても逃げてしまうことはなく、やがて突き潰されていく。こうして、廃材はこのような突き潰し作用を何度も繰り返し受ける内に次第に細解砕されていく。   In the pulverizing mixer 6, the one in which the binding strength of the asphalt in the waste material is sufficiently weakened by the warm bath pulverization process previously performed is sequentially sent to the downstream side by the stirring member 14 having a spiral arrangement. Force stirring. Then, as shown in FIG. 5, the other adjacent stirrer with respect to the waste material R rotating with the rotation of the stirring shafts 8 and 8 ′ so as to fit in the gap portion between the stirring members 14 of the one stirring shafts 8 and 8 ′. The tip of the stirring member 14 of the shafts 8 and 8 ′ is pierced into the waste material R as the stirring shafts 8 and 8 ′ rotate. At this time, since the waste material R is in a state where the upper and lower portions thereof are supported by the stirring member 14, the waste material R escapes even if the tip of the stirring member 14 of the other stirring shaft 8, 8 ′ is stuck. There will be nothing and it will eventually be crushed. In this way, the waste material is gradually shattered while repeatedly receiving such a crushing action.

そして、廃材が撹拌槽７内の所定レベルまで溜ると、撹拌槽７下部の排出口１６を適宜量開放して細解砕を終えた廃材の払い出しを行っていく。なお、排出口１６からの払い出し量によって撹拌槽７内の廃材の滞留時間が決定されるため、廃材の解砕具合を見ながら排出口１６の開度を適宜調整すると共に、排出される廃材の量と同量ずつ投入口１５から新たに廃材を投入していく。こうして、廃材が撹拌槽７の排出口１６から排出される頃には廃材はすっかり細解砕処理を終えており、これを別途用意したスクリーンなどで篩い分けるなどして廃材、特に排水性廃材から骨材を元の粒度のまま有効な状態で分離回収していく。   When the waste material accumulates to a predetermined level in the agitation tank 7, the discharge port 16 at the lower part of the agitation tank 7 is opened by an appropriate amount, and the waste material that has been finely crushed is discharged. In addition, since the residence time of the waste material in the agitation tank 7 is determined by the amount of discharge from the discharge port 16, the opening degree of the discharge port 16 is appropriately adjusted while observing the degree of disintegration of the waste material, and the waste material to be discharged Waste materials are newly input from the input port 15 by the same amount. Thus, when the waste material is discharged from the discharge port 16 of the agitation tank 7, the waste material has been completely pulverized, and the waste material is separated from the waste material, particularly drainage waste material by sieving it with a screen prepared separately. The aggregate is separated and recovered in an effective state with the original particle size.

なお、本実施例では温浴解砕手段として、図に示すように、貯留ホッパ２に貯留した廃材を温水に浸すような温浴解砕機を採用したが、これに限定するものではなく、例えばコンベヤ上を運搬中の廃材に対して上方より温水や高温の水蒸気を噴霧して浴びせた後に撹拌して温浴解砕するなど様々な方法を採用することもできる。   In the present embodiment, as shown in the figure, a hot bath crusher that immerses the waste material stored in the storage hopper 2 in hot water is used as the hot bath crushing means, but the invention is not limited to this. Various methods such as spraying warm water or high-temperature steam on the waste material being transported from above and stirring and crushing in a warm bath can also be adopted.
