本発明は、アスフアルト廃材の再生装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for recycling asphalt waste.
従来、道路舗装などに使用されたアスフアルト

しくない。 Asphalt concrete, which has traditionally been used for road paving, can be used for renovations etc.
It was thrown away as waste material. However, such disposal of asphalt waste not only causes economic loss but also causes waste material pollution. Moreover, it takes a lot of time and money to transport the waste materials. It is also unfavorable from the viewpoint of saving resources, which is a problem today.
そこで、アスフアルト廃材の再生処理が必要と
なるわけだが、従来は、この種の再生処理法とし
て、高周波で加熱する方法や、火災で直接吹付け
て加熱する方法や、水蒸気雰囲気にさらして加熱
する方法や、あるいは高温オイルによつて間接的
に加熱する方法などが提案されている。 Therefore, it is necessary to recycle the asphalt waste, but the conventional methods for this kind of recycling treatment include heating with high frequency waves, heating by direct spraying in a fire, and heating by exposing it to a steam atmosphere. Other methods have been proposed, such as a method of heating indirectly using high-temperature oil, etc.
本発明の目的は、このような実情に鑑みて、き

発明の実施態様を明らかにする。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be clarified by explaining one example of an asphalt waste recycling apparatus according to the present invention with reference to the drawings.

設けてある。 Inside the decomposition tank 4, a wire mesh 5, a steam pipe 3, and a decomposer 6 are installed in order from the top. The steam pipe 3 in the decomposition tank 4 is provided with holes for steam injection. As shown in the figure, the steam pipe 3 is provided below the wire mesh 5. In the illustrated example, a screw 8 is provided at the bottom of the decomposition tank 4. That Screw 8
Connect the hot elevator 9 to. A vibrating screen 10 is installed at a position to receive the decomposed recycled asphalt material falling from the upper end of the hot elevator 9. A sorting pipe 11 is provided there.

た蒸気パイプ３を配設してある。 A steam pipe 2 from the boiler 1 is connected to a decomposition tank 4,
It is connected to a screw 8 and a hot elevator 9, respectively. A steam pipe 3 with a small hole is arranged inside them.

加熱蒸気を蒸気パイプ２，３に送る。 The decomposition tank 4 is filled with water up to the water surface level X.
Therefore, the wire mesh 5 is located below the water surface. When a solid block 12 of asphalt waste is introduced from the top of the decomposition tank 4 as shown in the figure, the solid block 12 of asphalt waste sinks below the water surface and reaches the wire mesh 5 in the water. Solid blocks 12 of large size are stacked on a wire mesh 5. On the other hand, heated steam is sent from the boiler 1 to steam pipes 2 and 3.

アスフアルト廃材の分解効果が増進する。 Steam is injected into the water in the decomposition tank 4 from the holes in the steam pipe 3, and at that time, the steam also hits the asphalt waste on the wire mesh 5, increasing heat conduction.
The decomposition effect of asphalt waste is improved.

る。 The solid block 12 of asphalt waste material heated and softened on the wire mesh 5 passes through the wire mesh 5 and falls. Subsequently, the solid block 12 is decomposed by a decomposer 6, and further subjected to decomposition action while being conveyed by a screw 8 at the bottom of the decomposition tank 4. The recycled material thus decomposed is conveyed upward by a hot elevator 9 and sent to a vibrating sieve 10.
前述のように分解された再生素材を主原料とし
てアスフアルト合材を形成し、現在の道路舗装に
再生使用できるものである。 Asphalt composite material is formed using the recycled material decomposed as the main raw material as described above, and can be recycled and used for current road pavement.

のため、廃材落下時の衝撃を蒸気パイプに与えな
い。その結果、運転時のトラブルを避けることが
できる。これは、実用性の観点から非常に重要な
ことである。 According to the present invention, since a wire mesh is provided below the water surface of the decomposition tank, asphalt waste can be charged from the top of the decomposition tank in the form of solid blocks that have been ripped off from the pavement. Even if large foreign objects such as cement concrete or stones are mixed into the asphalt waste, the wire mesh will catch them. Therefore, the steam pipe is not affected by the impact when the waste material falls. As a result, troubles during driving can be avoided. This is very important from a practical standpoint.

噴射させるので、まず金網上でアスフアルト廃材
の固形ブロツクが湯と蒸気の熱により加熱され軟
化する。それにより、固形ブロツクは廃材の重量
も加わつて少しずつ金網を通過して落下する。 Steam is injected into the water from the holes in the steam pipe below the wire mesh, so first the solid blocks of asphalt waste are heated and softened by the heat of the hot water and steam on the wire mesh. As a result, the solid block, along with the weight of the waste material, gradually passes through the wire mesh and falls.

にそのまま沈下することがなく、金網の下方領域
の温湯を安定させやすい。特に金網の下側で蒸気
パイプから蒸気を噴射させているので、温度制御
を正確にしやすい。 Asphalt waste inserted from the top of the decomposition tank remains as it is.Asphalt waste inserted from the decomposition tank does not fall to the bottom of the decomposition tank as it is, and at least those of large size are caught by the wire mesh. Therefore, the cold solid blocks do not sink directly below the wire mesh, making it easier to stabilize the hot water in the area below the wire mesh. In particular, since the steam is injected from the steam pipe below the wire mesh, it is easy to control the temperature accurately.
金網の下方の水中で蒸気を吹きつけるため、加
熱容量が大きく、熱効率にムダが少なく、品質に
影響する処理温度の制御が精確かつ簡単である。 Since steam is blown into the water below the wire mesh, the heating capacity is large, there is little waste in thermal efficiency, and the processing temperature, which affects quality, can be precisely and easily controlled.
アスフアルト廃材を自重により分解層内の水の
中に沈下させ、途中に金網を設け、さらに分解層
の底部で分解するため、機械的負担が軽減され
る。 The asphalt waste is allowed to sink into the water in the decomposition layer under its own weight, a wire mesh is provided in the middle, and it is further decomposed at the bottom of the decomposition layer, which reduces the mechanical burden.
水の中で加熱および分解処理を連続して行える
ため、臭い、粉じんなどの公害が発生しない。 Since heating and decomposition treatment can be performed continuously in water, no pollution such as odor or dust is generated.
以上のように、本発明は廃材公害や質源節約の
ためという両課題を十分に解決できるものであ
る。 As described above, the present invention can sufficiently solve both the problems of waste material pollution and resource conservation.
