Description
本発明は、分離回収装置に関する。 The present invention relates to a separation and recovery device.
採石場や建設物工事現場においては、石等の固形物が廃棄物として発生し、これを現場外に搬出又は除去する必要がある。 At quarries and construction sites, solids such as stones are generated as waste, and it is necessary to carry them out or remove them.
一般にこれら固形物は重く、タンク等の収容容器に収容し、現場外部に搬出等する必要があるが、距離が長いと非常に労力が大きくなる。 Generally, these solids are heavy and need to be stored in a storage container such as a tank and carried out to the outside of the site, but if the distance is long, the labor becomes very large.
この問題を解決する一手段としては、例えば、真空タンクを用い、この真空タンクに吸引管を接続し、この真空タンクの真空から生ずる吸引力によってこれら固形物を吸引し、真空タンク内に固形物を収容しようとする技術がある。なお、この吸引が弱い場合によっては、真空タンクに更に吸引するための吸引機等を接続し、吸引力を高めようとする技術も考えられている（例えば下記特許文献１参照）。 As one means for solving this problem, for example, a vacuum tank is used, a suction pipe is connected to the vacuum tank, these solids are sucked by the suction force generated from the vacuum of the vacuum tank, and the solids are contained in the vacuum tank. There is a technique to accommodate. In some cases where the suction is weak, a technique of connecting a suction machine or the like for further suction to the vacuum tank to increase the suction force is also considered (see, for example, Patent Document 1 below).
しかしながら、上記技術では、搬送距離が長くなると、配管内の固形物が詰まってしまうといった課題がある。特に、吸引を一度停止させた場合、固形物が吸引管内に残るため、再度起動しようとしても管内が詰まってしまい、機能しなくなってしまうといった課題もある。 However, the above technique has a problem that solid matter in the pipe is clogged when the transport distance is long. In particular, when the suction is stopped once, the solid matter remains in the suction pipe, so that the pipe is clogged and does not function even if the suction is restarted.
そこで、本発明は上記課題に鑑み、長距離となっても安定的に駆動可能な固形物の分離回収装置を提供することを目的とする。 Therefore, in view of the above problems, an object of the present invention is to provide a solid matter separation / recovery device that can be stably driven even over a long distance.
上記課題を解決する本発明の一観点に係る固形物の分離回収装置は、固形物を吸引し、分離回収する固形物の分離回収装置であって、複数の導管と、複数の導管を接続するとともに吸引と配管中を圧送する吸引圧送装置が設けられた接続管と、を有する配管部材と、配管部材に接続され、配管部材内を吸引するとともに、吸引された固形物を大きさに応じて分離するサイクロン分級装置と、接続管の前記吸引圧送装置に圧縮空気を供給する空気圧縮装置と、サイクロン分級装置の一方の出口に接続され、サイクロン分級装置内の空気を吸引するとともに搬送配管中をも吸引する空気吸引装置と、を有する分離回収装置である。 The solid matter separation / recovery device according to one aspect of the present invention that solves the above problems is a solid matter separation / recovery device that sucks and separates and recovers solid matter, and connects a plurality of conduits and a plurality of conduits. A pipe member having a connecting pipe provided with a suction pumping device for sucking and pumping in the pipe, and a pipe member connected to the pipe member to suck the inside of the pipe member and sucked solid matter according to the size. It is connected to one outlet of the cyclone classification device to be separated, the air compression device that supplies compressed air to the suction pressure feeding device of the connecting pipe, and the cyclone classification device, and sucks the air in the cyclone classification device and in the transport pipe. It is a separation and recovery device having an air suction device that also sucks air.
以上、本発明は、固形物を吸引し配管中をプラス圧で圧送しながら回収装置側からの高真空空気吸引装置で吸引することでプラス圧送と吸引のマイナス真空圧による互いの相乗効果により長距離となっても安定的に駆動可能な固形物の分離回収装置を提供することができる。 As described above, the present invention is long due to the synergistic effect of positive pressure feeding and negative vacuum pressure of suction by sucking solid matter with a high vacuum air suction device from the recovery device side while sucking solid matter and pumping it in the pipe with positive pressure. It is possible to provide a solid matter separation / recovery device that can be stably driven even at a distance.
以下、本発明の実施形態について図面を用いて詳細に説明する。ただし、本発明は多くの異なる形態による実施が可能であり、以下に示す実施形態、実施例に記載の具体的な例示にのみ限定されるわけではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different embodiments, and is not limited to the specific examples described in the embodiments and examples shown below.
図１は本実施形態に係る分離回収装置（以下「本装置」という）１の概略図である。本図で示すように本装置１は固形物を吸引し分離回収する固形物の分離回収装置であって複数の導管２１、２３を接続するとともに圧縮空気を供給する空気圧縮装置４と供給口２２１が設けられた吸引圧送装置２２とを有する配管部材2において空気圧縮機４より圧縮空気を供給口２２１より供給することで真空を発生させ、吸い込み口２１３より固形物Sを吸引するとともに真空を発生させ、
吸引するために用いたエアーで導管２３中を圧送し吸引された固形物Sを大きさに応じて分級するサイクロン分級装置３とサイクル分級装置３の一方の出口３１に接続されサイクロン分級装置内の空気を吸引する高真空多風量吸引装置５とを有する装置である。本装置1は固形物Sを吸引するとともに配管中をエアー圧送し、固形物Sを分離回収する分離回収装置であって、上記の構成によって吸引し配管中をエアーで圧送するが搬送空気の風圧が徐々に低下してくるので、搬送能力が低下する。それを補うために先方から高真空多風量で吸引されるので両方の利点の相乗効果で長距離搬送となっても安定的に駆動可能な固形物の分離回収装置を提供することができる。
FIG. 1 is a schematic view of a separation / recovery device (hereinafter referred to as “the device”) 1 according to the present embodiment. As shown in this figure, the present device 1 is a solid matter separation / recovery device that sucks and separates / recovers solid matter, and is an air compressor 4 and a supply port 221 that connect a plurality of conduits 21 and 23 and supply compressed air. In the piping member 2 having the suction pressure feeding device 22 provided with the above, a vacuum is generated by supplying compressed air from the air compressor 4 from the supply port 221 and sucking the solid matter S from the suction port 213 and generating the vacuum. Let me
It is connected to one outlet 31 of the cyclone classifying device 3 and the cycle classifying device 3 which pumps the sucked solid matter S by pressure through the conduit 23 with the air used for suction and classifies the sucked solid matter S according to the size, and is inside the cyclone classifying device. It is a device having a high vacuum high air volume suction device 5 for sucking air. This device 1 is a separation and recovery device that sucks solid matter S and pumps air through the pipe to separate and recover the solid matter S. It sucks solid matter S and pumps it through the pipe with air according to the above configuration, but the wind pressure of the conveyed air. Gradually decreases, so that the carrying capacity decreases. In order to compensate for this, since suction is performed from the other side with a high vacuum and a large air volume, it is possible to provide a solid matter separation / recovery device that can be stably driven even during long-distance transport due to the synergistic effect of both advantages.
まず、本装置１において、配管部材２は、上記の通り、複数の導管２１、２３と、この複数の導管２１、２３を接続する吸引圧送装置２２を有する。図２に、吸引圧送装置２２及びこれに接続される導管２１、２３の一部についての断面の拡大図を示す。 First, in the present device 1, the piping member 2 has a plurality of conduits 21 and 23 and a suction pumping device 22 connecting the plurality of conduits 21 and 23 as described above. FIG. 2 shows an enlarged cross-sectional view of the suction pumping device 22 and a part of the conduits 21 and 23 connected to the suction pumping device 22.
本装置１の導管２１は、内部に空洞を備えた筒状の部材であり、固形物Sを吸い込むいわゆる吸い込み口２１3が形成された入り口側の導管２１と、これに吸引圧送装置２２を介して接続されサイクロン分級装置側に設けられる中間の導管２３と、を設けている。導管２１、２３は、固形物を吸い込んだ後これを運ぶ管として機能する。 The conduit 21 of the present device 1 is a tubular member having a cavity inside, and is via a conduit 21 on the inlet side where a so-called suction port 213 for sucking the solid matter S is formed, and a suction pumping device 22. An intermediate conduit 23, which is connected and provided on the cyclone classification device side, is provided. The conduits 21 and 23 function as pipes that suck in solids and then carry them.
吸引圧送装置２２の入り口側における空洞の径（内径）は、吸引及び分離回収の対象となる固形物の大きさによって異なるが、概ね２ｃｍ以上５ｃｍ以下であることが好ましい。また、吸引圧送装置２２の径（内径）は入り口側の導管２１の内径よりも少し小さいことが好ましく、例えば１．５ｃｍ以上４．５ｃｍ以下であることが好ましい。 The diameter (inner diameter) of the cavity on the inlet side of the suction pumping device 22 varies depending on the size of the solid material to be suctioned and separated and recovered, but is preferably about 2 cm or more and 5 cm or less. Further, the diameter (inner diameter) of the suction pumping device 22 is preferably slightly smaller than the inner diameter of the conduit 21 on the inlet side, and is preferably 1.5 cm or more and 4.5 cm or less, for example.
また、入り口側導管２１及び中間の導管２３の長さについても適宜調整可能であり限定されるわけではないが、入り口側の導管２１の長さとしては１ｍ以上２ｍ以下であることが好ましい。一方、中間の導管２３としては、１ｍ以上１５ｍ以下であることが好ましい。本装置１では、吸引圧送装置２２によってサイクロン分級装置３側に圧送することができるため、中間の導管２３の長さを長くすることが可能となる。 Further, the lengths of the inlet side conduit 21 and the intermediate conduit 23 can be appropriately adjusted and are not limited, but the length of the inlet side conduit 21 is preferably 1 m or more and 2 m or less. On the other hand, the intermediate conduit 23 is preferably 1 m or more and 15 m or less. In the present device 1, since the suction pumping device 22 can pump the cyclone to the cyclone classification device 3, the length of the intermediate conduit 23 can be increased.
また、入り口側導管２１及び中間の導管２３の材質としては、安定的に固形物Ｓを搬送することができる限りにおいて限定されるわけではないが、導管としての形状を保つことができる一方、吸い込み口２１3を固形物Ｓに向けて動かすことができる程度の柔軟性を持つことが好ましく、例えば樹脂又はゴムであることが好ましい。 Further, the materials of the inlet side conduit 21 and the intermediate conduit 23 are not limited as long as the solid material S can be stably conveyed, but the shape as a conduit can be maintained, while suction is performed. The mouth 213 is preferably flexible enough to move toward the solid S, preferably resin or rubber, for example.
また、入り口側の導管２１における吸引力、具体的には、固形物Ｓを吸引するために入り口側の導管２１の吸い込み口２１３近傍における導管２１内の真空圧は、限定されるわけではないが、例えば２０００ｍｍＨ２Ｏ以上３０００ｍｍＨ２Ｏ程度であることが好ましい。この範囲とすることで、砂や砂利を安定的に吸引し、配管中を圧送しサイクロン分級装置３方向に搬送することが可能となる。また、固形物Sは砂や砂利に限らない。 Further, the suction force in the inlet side conduit 21, specifically, the vacuum pressure in the conduit 21 in the vicinity of the suction port 213 of the inlet side conduit 21 for sucking the solid matter S is not limited. For example, it is preferably about 2000 mmH 2 O or more and about 3000 mmH 2 O. Within this range, sand and gravel can be stably sucked, pumped through the pipe, and transported in the three directions of the cyclone classification device. Further, the solid substance S is not limited to sand and gravel.
また、上記の記載から明らかなように、本装置１が吸引搬送する固形物Ｓは、砂や砂利、土、更にはこれらと水との混合物を典型的に想定することができる。より具体的に、砂や砂利の大きさ（最大幅）が、２０ｍｍ以上３０ｍｍ位の砂利であっても安定的に吸引及び搬送することができる。固形物Sは鉄粉その他粉体のものにも使用可能である。 Further, as is clear from the above description, the solid material S sucked and conveyed by the present apparatus 1 can typically be assumed to be sand, gravel, soil, or a mixture of these and water. More specifically, even if the size (maximum width) of sand or gravel is about 20 mm or more and 30 mm, it can be stably sucked and conveyed. The solid S can also be used for iron powder and other powders.
吸引圧送装置２２は、上記複数の導管２１、２３を接続するとともに、空気圧縮装置４に接続されており、空気圧縮装置４からの圧縮空気を圧縮空気導入管４１で受け入れ、固形物Sを吸引し、かつサイクロン分級装置３側に固形物を空気とともに送る機能を備える。 The suction pumping device 22 connects the plurality of conduits 21 and 23, and is also connected to the air compression device 4. The compressed air from the air compression device 4 is received by the compressed air introduction pipe 41, and the solid matter S is sucked. In addition, it has a function of sending solid matter together with air to the cyclone classification device 3.
図２の吸引圧送装置２２の構成としては、限定されるわけではないが、吸引し圧送できるエジェクターであることがより高精度な吸引圧送を行うことができる観点から好ましい。このエジェクターの断面イメージは上記図に示すとおりである。より具体的に説明すると、吸引圧送装置２２内において入り口側の内管Aは先端が若干テーパー型に細くなっていて外管Bは内管Aの外面のテーパーに沿って若干の隙間を有し圧縮空気がリング状に吹き出すような構造となっている。代案としてリング状の代わりに直径２〜３ｍｍ程度の穴をリング状に吹き出す位置にリング上の隙間の全面積に相当する穴をあけることでも良く、設けた穴から圧縮空気を吹き出す構造である。吸引力を発生させるため吸引圧送装置２２に接続された空気圧縮装置４から圧縮空気導入管４１で供給口２２１に接続され、吸引圧送装置２２から高速で高圧空気が吹き出される。吹き出された圧縮空気が管部２２３の広い面積のところへ放出されるため、空気が膨張して真空状態となり吸引力が発生し固形物Sを吸引する。常時上記のエアーの流れがあり、接続管２１、２３中を空気が流れ、吸引された固形物Sをエアー圧送し、サイクロン分級装置方向へ搬送していく。搬送距離が長くなってきた場合、導管２３中を圧送するだけでは固形物Sが配管途中で停滞してしまい、閉塞し搬送ができなくなるため、これを防ぐため後方に設置された高真空圧で多風量を発生させることができる空気吸引装置5を設け、前段として分離サイクロン３と集塵フィルター6を有しているが、空気吸引装置5の空気吸引力が大きいので、導管２３を圧送されてきた空気を吸引し導管２１２中の固形物Sを吸引搬送することができる。圧送搬送の機能と吸引搬送の機能の相乗効果で配管中の固形物Sのつまりを防止し、長距離搬送が可能となる。空気吸引装置5の駆動源は空気圧縮装置４の圧縮エアーを供給する型のエジェクターである。途中にサイクロンによる分離機能を有し、フィルターにより微粒子を回収する装置が設置されているので、固形物の吸引―分離回収―粉塵回収処理が一貫してできる装置である。真空力を活用して、吸引・搬送・分離・集塵をしているため、吸い込み口２１３以外の導管、分離サイクロン、回収タンク、フィルター６及び回収タンクまで、全体装置について外気が入らない密閉構造となっている。 The configuration of the suction pumping device 22 of FIG. 2 is not limited, but it is preferable that the ejector is capable of suction and pumping from the viewpoint of being able to perform suction and pumping with higher accuracy. The cross-sectional image of this ejector is as shown in the above figure. More specifically, in the suction pumping device 22, the inner tube A on the inlet side has a slightly tapered tip, and the outer tube B has a slight gap along the taper of the outer surface of the inner tube A. The structure is such that compressed air blows out in a ring shape. As an alternative, instead of the ring shape, a hole having a diameter of about 2 to 3 mm may be formed in a ring shape at a position corresponding to the entire area of the gap on the ring, and the structure is such that compressed air is blown out from the provided hole. The air compression device 4 connected to the suction pressure feeding device 22 is connected to the supply port 221 by a compressed air introduction pipe 41 in order to generate a suction force, and high-pressure air is blown out from the suction pressure feeding device 22 at high speed. Since the blown out compressed air is released to a wide area of the pipe portion 223, the air expands to a vacuum state, a suction force is generated, and the solid matter S is sucked. There is always the above-mentioned air flow, air flows through the connecting pipes 21 and 23, and the sucked solid matter S is pumped by air and conveyed toward the cyclone classifier. When the transport distance becomes long, the solid material S stagnates in the middle of the piping just by pumping through the conduit 23, and it is blocked and cannot be transported. To prevent this, a high vacuum pressure installed at the rear is used. An air suction device 5 capable of generating a large amount of air is provided, and a separation cyclone 3 and a dust collection filter 6 are provided as a front stage. However, since the air suction force of the air suction device 5 is large, the conduit 23 is evacuated. The air can be sucked and the solid matter S in the conduit 212 can be sucked and conveyed. The synergistic effect of the pumping transport function and the suction transport function prevents clogging of the solid matter S in the piping and enables long-distance transport. The drive source of the air suction device 5 is an ejector of a type that supplies the compressed air of the air compression device 4. Since a device that has a separation function by a cyclone and collects fine particles by a filter is installed on the way, it is a device that can consistently perform suction-separation recovery-dust recovery processing of solid matter. Since suction, transportation, separation, and dust collection are performed using vacuum force, the entire device is sealed so that outside air does not enter, including the conduit other than the suction port 213, the separation cyclone, the recovery tank, the filter 6, and the recovery tank. It has become.
なお、複数の管は、本図の例では二つとなっているが、より長距離を確実に固形物を吸引搬送する必要がある場合は、配管を少なくとも３つ設け、吸引圧送装置２２を２つ設けて二段階吸引することとしてもよい。この場合のイメージ図を図３に示しておく。 In addition, although the plurality of pipes is two in the example of this figure, when it is necessary to surely suck and transport the solid matter over a longer distance, at least three pipes are provided and the suction pumping device 22 is provided with two. It may be provided and suction may be performed in two stages. An image diagram in this case is shown in FIG.
また、本装置１は、上記の通り、吸引された固形物Ｓを大きさに応じて分離するサイクロン分級装置３を備えている。 Further, as described above, the present device 1 includes a cyclone classification device 3 that separates the sucked solid matter S according to the size.
本装置１におけるサイクロン分級装置３は、サイクロンを用いることによって分級するすなわち固形物の大きさによってその分離を行う装置である。より具体的には、内部の空洞が円筒形状となっている円筒形状部分３３と、この円筒形状部分の鉛直方向下側に接続される円錐形状の内部空洞を有する円錐形状部分３４とを有し、円筒形状部分３３の上部には一方の出口３１、下方の円錐形状部分３４の下部には他方の出口３２を備えている。本装置１ではこの構成により、固形物Ｓの大きさによって分級することが可能となる。具体的には、上部の円筒形状部分３３の上部近傍に中間の導管２３が接続されており、この導管２３から排出される固形物Ｓを含んだ空気の流れによってサイクロンが形成され、円筒形状部分３３及び円錐形状部分３４に沿って進むことにより固形物Ｓの大きさが選り分けられることになる。より具体的には大きな固形物が下部の他方の出口３２に、小さな固形物は上部の一方の出口３１から排出されていくことになる。 The cyclone classification device 3 in the present device 1 is a device that classifies by using a cyclone, that is, separates the cyclone according to the size of the solid matter. More specifically, it has a cylindrical portion 33 in which the internal cavity has a cylindrical shape, and a conical portion 34 having a conical internal cavity connected to the lower side in the vertical direction of the cylindrical portion. The cylindrical portion 33 is provided with one outlet 31, and the lower conical portion 34 is provided with the other outlet 32. With this configuration, the apparatus 1 can be classified according to the size of the solid matter S. Specifically, an intermediate conduit 23 is connected to the vicinity of the upper portion of the upper cylindrical portion 33, and a cyclone is formed by the flow of air containing the solid matter S discharged from the conduit 23, and the cylindrical portion is formed. The size of the solid S is selected by advancing along the 33 and the conical portion 34. More specifically, the large solid matter is discharged from the lower outlet 32, and the small solid matter is discharged from the upper outlet 31.
ところで、本装置１では、下部の他方の出口３２の下部に、容器３５を備えている。この容器３５を備えることで比較的大きな固形物を収容することができる。ただし、本装置１では、吸引圧送装置２２によって空気で圧送される一方、サイクロン分級装置３内部も吸引されるため、この内部空間を負に維持しておく必要から、サイクロン分級装置３内部と接続される一方で密封された容器３５であることが好ましい。また他の機器も外から空気が入らない密封構造とする。このようにすることで、配管部材２内及びサイクロン型分級装置３内の圧力を維持することができるようになる。 By the way, in the present apparatus 1, a container 35 is provided in the lower part of the other outlet 32 in the lower part. By providing the container 35, a relatively large solid substance can be stored. However, in this device 1, while being pumped by air by the suction pumping device 22, the inside of the cyclone classification device 3 is also sucked. Therefore, since it is necessary to maintain this internal space negatively, it is connected to the inside of the cyclone classifying device 3. On the other hand, it is preferably a sealed container 35. In addition, other equipment will also have a sealed structure that prevents air from entering from the outside. By doing so, it becomes possible to maintain the pressure in the piping member 2 and the cyclone type classification device 3.
なお、本装置１におけるサイクロン分級装置３の円筒形状部分３３の内径は、上記機能を有する限りにおいて限定されるわけではないが、例えば、内径として２００ｍｍ以上５００ｍｍ以下であることが好ましい。また、円筒形状部分３３及び円錐形状部分３４の長さとしても、限定されるわけではないが、例えば４００ｍｍ以上１５００ｍｍ以下であることが好ましい。 The inner diameter of the cylindrical portion 33 of the cyclone classification device 3 in the present device 1 is not limited as long as it has the above functions, but for example, the inner diameter is preferably 200 mm or more and 500 mm or less. Further, the lengths of the cylindrical portion 33 and the conical portion 34 are not limited, but are preferably 400 mm or more and 1500 mm or less, for example.
繰り返しとなるが、本装置１のサイクロン分級装置３によって、比較的大きな固形物については、鉛直方向下部の出口３２から排出され、比較的細かな固形物については、鉛直方向上部に設けられる出口３１から排出される。特に、鉛直方向上部に設けられる一方の出口３１からは、空気が多く排出される。 Again, the cyclone classification device 3 of the present device 1 discharges relatively large solids from the outlet 32 at the lower part in the vertical direction, and relatively fine solids are discharged from the outlet 31 provided at the upper part in the vertical direction. Is discharged from. In particular, a large amount of air is discharged from one of the outlets 31 provided at the upper part in the vertical direction.
また、本装置１では、上記の通り、接続管の供給口２２は圧縮空気を供給する空気圧縮装置４に接続されており、この空気圧縮装置４には圧縮空気導入管４１が接続されており、吸引圧送装置２２の供給口２２１に圧縮空気を送る。この空気圧縮装置４の構成としては特に限定されるわけではないが、例えばコンプレッサであることが好ましい。 Further, in the present device 1, as described above, the supply port 22 of the connecting pipe is connected to the air compression device 4 that supplies compressed air, and the compressed air introduction pipe 41 is connected to the air compression device 4. , Compressed air is sent to the supply port 221 of the suction pressure feeding device 22. The configuration of the air compressor 4 is not particularly limited, but it is preferably a compressor, for example.
また、本装置１において、空気吸引装置５は、上記の通り、サイクロン分級装置３の上方の出口３１に接続され、サイクロン分級装置３内の空気を吸引する。本装置１では、吸引圧送装置２２により導管２１中を圧送されてきており、更にサイクロン分級装置３内をさらに吸引することで、サイクロンによる分級効率を高めることが可能となる。 Further, in the present device 1, the air suction device 5 is connected to the outlet 31 above the cyclone classification device 3 as described above, and sucks the air in the cyclone classification device 3. In the present device 1, the suction and pressure feeding device 22 has pumped the inside of the conduit 21, and further suctioning the inside of the cyclone classification device 3 makes it possible to improve the classification efficiency by the cyclone.
ここで、空気吸引装置５が吸引する能力については、上記機能を有することができる限りにおいて特に限定されるわけではないが、サイクロン分級装置３内の分級性能を上げるため及び導管２１中の固形物Sを吸引搬送させるため空気吸引装置５の真空圧力が７０００ｍｍＨ２Ｏ以上９０００ｍｍＨ２Ｏ程度の高真空でかつ吸引風量が多いことが好ましい。 Here, the suction capacity of the air suction device 5 is not particularly limited as long as it can have the above function, but in order to improve the classification performance in the cyclone classification device 3 and the solid matter in the conduit 21. In order to suck and convey S, it is preferable that the vacuum pressure of the air suction device 5 is a high vacuum of about 7,000 mmH 2 O or more and about 9000 mmH 2 O and the suction air volume is large.
また、空気吸引装置５の構成としても特に限定されるわけではないが、エジェクターであることは好ましい一例である。この場合の断面のイメージを図４に示しておく。具体的には、サイクロン分級装置３から排出される空気をエジェクターに入れることによって、サイクロン分級装置３内の空気を吸引し、より高い真空とすることが可能となる。なおこのエジェクターの場合、上記空気圧縮装置４に接続され、この空気圧縮装置４から圧縮空気の供給を受けて動作するようにしておくことが好ましい。 Further, the configuration of the air suction device 5 is not particularly limited, but an ejector is a preferable example. An image of the cross section in this case is shown in FIG. Specifically, by putting the air discharged from the cyclone classification device 3 into the ejector, the air in the cyclone classification device 3 can be sucked and a higher vacuum can be obtained. In the case of this ejector, it is preferable that the ejector is connected to the air compression device 4 and is operated by receiving the supply of compressed air from the air compression device 4.
また、本装置１では、空気吸引装置5の前段に、フィルター６を備えることが好ましい。このようにすることで、サイクロン分級装置３の一方の出口３１から排出される比較的細かな固形物が空気吸引装置内部５に入ってしまうことを防止するとともに、ここに固形物回収容器を備えさせることで、この固形物を分離回収することが可能となる。また、フィルター６を備える場合、このフィルターを備えるとともに固形物を収容する収容容器６１を設けておくことが好ましい。このようにすることで、空気吸引を行った場合に、この空気吸引装置内５に固形物が入ってしまうことを防止するとともに、この収容容器６１に固形物を安定的に収容することが可能となる。 Further, in the present device 1, it is preferable that the filter 6 is provided in front of the air suction device 5. By doing so, it is possible to prevent relatively fine solid matter discharged from one outlet 31 of the cyclone classification device 3 from entering the inside 5 of the air suction device, and a solid matter recovery container is provided here. By doing so, it becomes possible to separate and recover this solid matter. When the filter 6 is provided, it is preferable to provide the filter and a storage container 61 for accommodating solid matter. By doing so, when air suction is performed, it is possible to prevent solids from entering the air suction device 5 and to stably store the solids in the storage container 61. It becomes.
（動作）
ここで、上記の記載から明らかであるが、本装置１の駆動動作について説明する。
(motion)
Here, as is clear from the above description, the driving operation of the present device 1 will be described.
まず、本装置１を駆動させる場合、空気圧縮装置４で空気吸引装置５を駆動させ、サイクロン分級装置３内を先に真空にする。その後、空気圧縮装置４から圧縮空気導入管４１で配管部材２の吸引圧送装置２２に圧縮された空気を送ることにする。すなわち、サイクロン分級装置３内部よりも先に接続管に対して圧縮された空気を送ってしまうと、サイクロン分級装置３内の圧力が低くなっていないため、導管内に固形物が残っていた場合詰まってしまうおそれがある。これに対し、サイクロン分級装置３内を先に真空にすることで、このように詰まってしまうおそれを少なくすることができる。一方、本装置１が駆動している場合は、吸引圧送装置２２に空気圧縮装置４からの圧縮空気の供給をやめ、動作を止めてから、空気吸引装置５を止める。このようにすることで、サイクロン分級装置３を最後まで駆動させ、導管の途中で固形物が止まってしまわないようにすることができる。 First, when the present device 1 is driven, the air compression device 4 drives the air suction device 5, and the inside of the cyclone classification device 3 is first evacuated. After that, the compressed air is sent from the air compression device 4 to the suction pressure feeding device 22 of the piping member 2 by the compressed air introduction pipe 41. That is, if compressed air is sent to the connecting pipe before the inside of the cyclone classification device 3, the pressure inside the cyclone classification device 3 is not low, so that solid matter remains in the conduit. There is a risk of clogging. On the other hand, by evacuating the inside of the cyclone classification device 3 first, the possibility of clogging in this way can be reduced. On the other hand, when the present device 1 is being driven, the supply of compressed air from the air compression device 4 to the suction pumping device 22 is stopped, the operation is stopped, and then the air suction device 5 is stopped. By doing so, the cyclone classification device 3 can be driven to the end so that the solid matter does not stop in the middle of the conduit.
以上、本装置１は、長距離となっても安定的に駆動可能な固形物の分離回収装置となる。 As described above, the present device 1 is a solid substance separation / recovery device that can be stably driven even over a long distance.
本装置は、固形物の分離回収装置として産業上の利用可能性がある。
This device has industrial applicability as a solid matter separation and recovery device.
