本発明は解体現場で発生したコンクリート廃材
から骨材を分級して回収再生する装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for classifying, recovering and recycling aggregate from concrete waste generated at a demolition site.
（従来の技術）
解体現場で発生するコンクリート廃材は、従来
埋め立てなどに利用される程度で殆んど骨材の回
収、再生が行われていない。(Conventional technology) Concrete waste generated at demolition sites has conventionally been used in landfills, and the aggregate has hardly been recovered or recycled.
ところが、省資源の観点から近来コンクリート
廃材に再生利用が叫ばれている。我国では近い将

材を回収再生することは大きな課題となつてい
る。 However, in recent years, there has been a call for recycling of concrete waste from the perspective of resource conservation. In Japan, many concrete buildings will reach the end of their useful life in the near future, and it is expected that a large amount of concrete waste will be generated. Therefore, recovering and recycling aggregate from concrete waste has become a major issue.
コンクリート廃材からの骨材の回収、再生する
には、システムと該システムで使用する装置の開
発が必要となつてくる。 In order to recover and recycle aggregate from concrete waste, it is necessary to develop a system and the equipment used in the system.
コンクリート廃材を回収、再生するシステムは
種々公知であるが、再生システムにかける前に再
生し易い状態まで前処理することが必要である。 Various systems are known for collecting and recycling concrete waste, but it is necessary to pre-treat it to a state where it can be easily recycled before applying it to the recycling system.
そこで、廃材コンクリートを大塊ブロツクと小

このようにして得られた原料コンクリート塊は
異物の含有量が少ないので再生システムが簡単と
なるものである。 Therefore, the waste concrete is divided into large blocks and small blocks, the large blocks are crushed into small blocks, the reinforcing bars are removed, and the crushed small blocks are merged with the small blocks to be used as earth, sand, wood, cloth, etc. The foreign matter was removed, this was further crushed, and the reinforcing steel was removed.
A pretreatment system has been proposed in which a concrete mass of 150 mm or less is made into a raw material concrete mass, and a small mass of 40 mm or more of the selected earth and sand is added thereto. (Japanese Patent Application No. 57-153574) Since the raw material concrete mass obtained in this way has a low content of foreign matter, the recycling system is simple.

（発明が解決しようとする課題）
ところが、上記のような回収システムで回収さ

つた骨材の回収を行なうのが通常であり（特開昭
50−61878号公報参照）、必要に応じて小粒径の１

粒径だけを回収したり選択回収することはできな
かつた。 As a system for obtaining recycled aggregate from the raw material concrete mass, the raw material concrete is crushed to remove the remaining reinforcing bars, and this is divided into fine particles of 10 mm or less, coarse particles of 10 mm to 40 mm, and large particles of 40 mm or more, Coarse particles are crushed by a crusher and passed through a screen, on the other hand, coarse aggregate with a size of 5 to 25 mm is regenerated, and fine particles of 5 mm or less that have been sieved with a screen are combined with the fine particles and passed through the device of the present invention. We have already proposed a method in which the large particles are returned to the raw concrete mass and crushed again. (Patent Application No. 57-153575) (Problem to be Solved by the Invention) However, when recovering aggregates recovered by the recovery system as described above, it is usually necessary to recover aggregates with two types of particle sizes. It is normal to perform
50-61878), small particle size 1 as necessary.
It has not been possible to selectively collect only one type of particle size, or only two types of particle sizes.
そこで、本発明の目的は、上述のシステムにお
いて、10mm以下の細粒を粉砕して少なくとも５mm
以下の２種類の粒径と更には５mm以下の１種類だ

である。 Therefore, an object of the present invention is to crush fine particles of 10 mm or less in the above-mentioned system to at least 5 mm
In addition to being able to selectively classify the following two types of particle sizes and furthermore, only one type of particle size of 5 mm or less,
The present invention provides an apparatus that effectively removes fine powder.

夫々の粒の一例を上げると、Ａ，Ｂ＝1.2〜５mm
Ｃ＝0.15〜1.2mm Ｄ＝0.15mm以下である。 The recovered aggregate M 1 to be crushed with a size of 10 mm or less and the recovered aggregate M 2 returned as necessary are supplied to the chute 1 and are subjected to centrifugal force by the discharge blade 3 of the plate body 2 in the radial direction. It is ejected, collides with the collision plate 5, and is crushed. The fine powder generated at this time is collected from the suction port 10,
It is collected into the dust collector 8 via the duct 9. Most of the crushed recovered aggregate particles are less than 5mm in size.
It is supplied to the hopper 13 via the chute 7 and the conveyance path 11. The collected aggregate particles in the hopper 13 partially contain fine powder and have various particle sizes. The collected aggregate particles fall down the partition 17 and are scattered by the vibrating feeder 18, and are divided into A particles, B particles, C particles,
and D are transported to the compartment of fine powder. In this case, an example of each grain is A, B = 1.2 to 5 mm.
C=0.15 to 1.2 mm D=0.15 mm or less.

Recovered aggregate grains (grains A and B
By setting the switching damper 22 to the forward rotation position, all of the grains (A and B mixed grains) are transferred to the chute 25.
It is possible to further improve the separation of the fine powder by introducing it into the crusher again from the conveyance path 27, and by setting the switching damper 22 to the post-rotation position, all of the powder (mixed grains A and B) can be shunted. 26
It is also now possible to supply and collect it. Further, by setting the switching damper 22 to the neutral position as shown in the figure, it is also possible to feed the A-grain partitioned portion to the chute 25 and the B-grain partitioned portion to the chute 26.
前述のように、切換ダンパー２２はＡ粒、Ｂ粒

合を多くできるものとなる。 As mentioned above, the switching damper 22 not only returns grains A and B to the crusher when they still have a large amount of fine powder attached to them, but also returns them to the crusher when they are repeatedly crushed to fall onto the planned part of grain C. This means that only fine sand aggregate with small particle size will be collected and recycled. In addition, by doing so, it is possible to increase the proportion of aggregates with small particle sizes among the aggregates to be recovered.

Furthermore, two types of aggregate can be recovered. Moreover, since these selections can be made only by rotating the switching damper, no separate crusher or classifier is required, resulting in low cost.
又、微粉付着量の少ない再生骨材を得ることも
できるものである。 Moreover, it is also possible to obtain recycled aggregate with a small amount of fine particles attached.
