【発明の属する技術分野】
本発明は、混練機能付き吸引車に関し、より詳しくは、吸引機能と吸引物混練機能の双方を備えるとともに貯留タンク内において回転軸から放射状に複数の攪拌部材を延出させ該攪拌部材を回転軸の軸長方向に沿って相互に間隔をあけて延出させることにより、吸引許容容積を大きく確保できるとともに、汚泥固体成分の沈殿防止及びモルタル化汚泥の固化防止を行い運搬後に吸引汚泥を速やかに排出することができる混練機能付き吸引車に関する。
【0002】
【従来の技術】
建設現場における各種掘削工事では、掘削土砂が産業廃棄物として生じる。産業廃棄物としての土砂は、そのままトラックで廃棄処理場まで運ばれるか、もしくは、水を含ませて汚泥とされ吸引ポンプ車で吸引されて廃棄物処理場まで運ばれている。
また、汚泥は工事現場の攪拌処理施設でセメントと共に混練され、この混練されたもの(モルタル化汚泥)がミキサー車又は吸引車で別の建設現場まで運ばれ、ここで建設用資材として再利用されることもある。
【0003】
【発明が解決しようとする課題】
しかしながら、前記した従来の技術には、以下のような課題が存在した。
従来の吸引ポンプ車は貯留タンク内に混練装置を備えていなかったため、吸引した汚泥のうち砂利、砂、粘土等の固体成分が運搬中に貯留タンク内底面に堆積し、この堆積物が廃棄物処理場において排出口から速やかに排出されず、貯留タンク内に大量に留まってしまうこともあった。
また、従来の吸引車は貯留タンク内に混練装置を備えていなかったので、モルタル化汚泥を運搬した場合、再利用現場に到着したときにはモルタル化汚泥の硬化が進んでいる。硬化が進んでしまうと、モルタル化汚泥をタンクからスムースに排出することができず、モルタル化汚泥がタンク内に大量に留まってしまうこともあった。
【0004】
本発明は、このような実情に鑑みてなされたもので、吸引機能と吸引物混練機能の双方を備えるとともに貯留タンク内において回転軸から放射状に複数の攪拌部材を延出させ該攪拌部材を回転軸の軸長方向に沿って相互に間隔をあけて延出させることにより、吸引許容容積を大きく確保できるとともに、汚泥発生現場にて汚泥を混練しこれを埋め戻し土として排出することができ、また、排出する汚泥固体成分の沈殿防止及びモルタル化汚泥の固化防止を行い運搬後に吸引汚泥を速やかに排出することができる混練機能付き吸引車の提供を目的とする。

【0013】
【発明の実施の形態】
本発明の実施形態について、図面を参照しつつ説明する。
図1は、本発明に係る混練機能付き吸引車を示す側面図である。図2は、図1に示す混練機能付き吸引車の部分断面後面図である。図3は、本発明における混練装置の一例を示す側面図である。図4は、本発明における混練装置の一例を示す後面図である。
本発明に係る混練機能付き吸引車(1)は、ホース(2)と、貯留タンク(3)と、真空ポンプ(4)と、混練装置(5)とが車両に搭載されてなるものである。
以下、これら構成要素について順次、詳説する。
【0014】
ホース(2)は、汚泥状廃棄物を吸引するものである。このホース(2)は可撓性を有し、基端部が吸引管(6)(図2、3参照)を介して貯留タンク(3)に接続されている。ホース(2)の先端部は汚泥状廃棄物の中に挿入される。
【0015】
貯留タンク(3)は、ホース(2)を通じて吸引される汚泥状廃棄物或いはそのモルタル化物を貯留するものである。貯留タンク(3)は横置円筒状に形成されており、前端部は円板状部(7)によって封じられ、後端部は円板状の蓋(8)によって開閉可能に封じられている。
蓋(8)の下部には開閉バルブ付きの排出口(9)が設けられており、貯留タンク(3)内の汚泥状廃棄物をこの排出口(9)を通じて排出することができる。
貯留タンク(3)の後端部には吸引管(6)が設けられており、汚泥状廃棄物はこの吸引管(6)を通じて貯留タンク(3)内に吸引される。
また、貯留タンク(3)の上部は、ポンプ接続管(10)(図1参照)を介して真空ポンプ(4)と接続されており、貯留タンク(3)内部はこの真空ポンプ(4)によって減圧され、汚泥状廃棄物の吸引力を生じることができる。
【0016】
貯留タンク(3)の後端部は、貯留タンク(3)が車両のシャシー(11)上で起伏できるようにシャシー(11)上に回動可能に連結されている。貯留タンク(3)とシャシー(11)の間には、貯留タンク(3)の前側が上下するように貯留タンク(3)を起伏させるシリンダ装置(12)が設けられている。
【0017】
また、貯留タンク(3)の上部にはセメント投入口(13)(図3参照)が設けられており、このセメント投入口(13)からセメントを投入することができる。このセメント投入口(13)は内部点検口としても機能することができる。
【0018】
真空ポンプ(4)は、貯留タンク(3)内を減圧して該タンク(3)内に吸引力を生じさせるものである。真空ポンプ(4)と貯留タンク(3)は、ポンプ接続管(10)を介して接続されている。真空ポンプ(4)の種類は特に限定されるものではないが、例えば、ルーツブロワ型のものを使用することができる。
【0019】
混練装置(5)は、貯留タンク(3)内の汚泥状廃棄物或いはそのモルタル化物を攪拌混練するものである。
混練装置(5)は、貯留タンク(3)内に回転可能に配置された回転軸(14)と、この回転軸(14)を回転駆動する駆動装置(15)と、回転軸(14)から放射状に延出された複数の攪拌部材(16)とからなり、攪拌部材(16)の一部又は全部が回転軸(14)にその軸長方向に相互に間隔をあけて取り付けられている(図3参照)。
駆動装置(15)の駆動方式は特に限定されるものではないが、例えば油圧駆動方式を採用することができ、この場合、走行用駆動エンジンの出力の一部で油圧ポンプを作動させ、そのポンプから得られる油圧で油圧モータを作動させる方式等を採用することができる。油圧モータは電動モータに比べて格段にコンパクトであり、また、慣性が小さい上、無段変速が可能であるから、混練装置において多くの利点を有する。
【0020】
攪拌部材(16)の全部が回転軸(14)にその軸長方向に相互に間隔をあけて取り付けられる例としては図3に示す状態を挙げることができ、攪拌部材(16)の一部が回転軸(14)にその軸長方向に相互に間隔をあけて取り付けられる例としては図5に示す状態を挙げることができる。
つまり、図5に示す状態では、攪拌部材(16A),(16A)は回転軸(14)にその軸長方向に相互に間隔をあけて取り付けられるが、攪拌部材(16A)と攪拌部材(16B)は回転軸(14)にその軸長方向において同じ位置に取り付けられる。
【0021】
回転軸(14)は、横置筒状に形成された貯留タンク(3)の軸長方向に沿って配置されており、その前端部、後端部はそれぞれ、貯留タンク(3)内に設けた軸受部材(17)(図3参照)によって回転自在に支持されている。
回転軸(14)の前端部は貯留タンク(3)の前端部から外部へ突出している。回転軸(14)の前端部は、駆動装置(15)から延出される回転駆動軸(18)と結合されている。
【0022】
駆動装置(15)は、回転軸(14)を回転駆動するものであり、貯留タンク(3)の前方に配置されている。その回転駆動軸(18)は、貯留タンク(3)の動きに応じて上下方向に移動可能及び傾斜可能とされており、これにより、回転駆動軸(18)と回転軸(14)の結合状態を維持したまま、貯留タンク(3)のダンプアップをすることができる。
【0023】
攪拌部材(16)は、貯留タンク(3)内の汚泥状廃棄物を攪拌するものであり、その攪拌動作により、汚泥状廃棄物を混練することができる。攪拌部材(16)は、図2に例示する円周(C)に沿って回転する。
攪拌部材(16)は、回転軸(14)から放射状に複数本延出されており、攪拌部材(16)の一部又は全部が回転軸(14)にその軸長方向に相互に間隔をあけて取り付けられている。
【0024】
尚、本発明においては、攪拌部材(16)の取付間隔(L)(図3参照)、或いは攪拌部材(16)が回転軸周りに互いになす角度(θ)(図4参照)の少なくともいずれか一方が変更可能とされていることが好ましい。
そのいずれか一方を変更可能とすることにより、汚泥状廃棄物の混練具合を調節することができる。
【0025】
また、攪拌部材(16)は回転軸(14)に着脱可能に取り付けられていることが好ましい。着脱可能に取り付けることにより、必要に応じて攪拌部材(16)の数を増減することができる。図3乃至5に示す例では、攪拌部材(16)の基端部が2つに分割可能なリング状に構成され、該リング状部(19)の内周面で回転軸(14)の外周面を締め付けるようになっている。回転軸(14)に攪拌部材(16)を取り付けるときにはリング状部(19)を構成する2つのC字状部(19a),(19b)をボルトとナットでフランジ結合し、取り外すときにはボルトとナットの螺合を解除してリング状部(19)を2つに分割すればよい。
【0026】
攪拌部材(16)の取付間隔(L)と、攪拌部材(16)が回転軸周りに互いになす角度(θ)の変更は、例えば、上記取付構造を利用して行うことができる。つまり、リング状部(19)が分割された状態の攪拌部材(16)を回転軸(14)の所望の箇所に位置させ、ボルトとナットで2つのC字状部(19a),(19b)を結合してリング状部(19)を形成することにより、攪拌部材(16)を新たな位置に取り付けることができる。
【0027】
尚、攪拌部材(16)は回転軸(14)から延出される支持部材(20)と、この支持部材(20)の先端に取り付けられた攪拌羽根(21)とから構成することができる。この構成において、攪拌羽根(21)は、支持部材(20)への取付角度が変更可能とされていることが好ましい。攪拌羽根(21)の取付角度を変更することにより、汚泥状廃棄物の混練具合を調節することができる。
【0028】
図3乃至5に示す例では、支持部材(20)は棒状、攪拌羽根(21)は板状とされている。攪拌羽根(21)の回転軸(14)側には支持部材(20)と結合するための第1フランジ部(22)(図5参照)が設けられており、支持部材(20)の先端には、攪拌羽根(21)の第1フランジ部(22)と結合される第2フランジ部(23)が設けられている。各フランジ部には複数のボルト挿通孔が形成されており、互いのボルト挿通孔を重合一致させ、このボルト挿通孔にボルトを挿入しこのボルトにナットを螺合することにより、攪拌羽根(21)と支持部材(20)を結合することができる。
攪拌羽根(21)の取付角度を変更する際には、まず、ボルトとナットの螺合を解除してボルトを抜き取り、次に第1フランジ部(22)を回転させて重合一致するボルト挿通孔をずらし、その状態で第1フランジ部(22)と第2フランジ部(23)をボルトとナットで結合すればよい。
【0029】
また、攪拌部材(16)を、回転軸(14)から延出される支持部材(20)と、この支持部材(20)の先端に取り付けられた攪拌羽根(21)とから構成する場合、攪拌羽根(21)は、貯留タンク内面(24)(図4参照)に接触する部分が合成ゴム等の弾性部材から構成され、貯留タンク内面(24)に接触した際にその弾性部分(21a)が該内面(24)に沿って変形し得るように構成されていることが好ましい。
攪拌羽根(21)をこのように構成することにより、貯留タンク内面(24)付近の汚泥状廃棄物をも確実に混練することができる。この場合、回転軸(14)の位置を貯留タンク(3)の中心位置より低くし、弾性部分(21a)が貯留タンク(3)内底面に接触するように構成すれば、沈殿しようとする汚泥の砂や粘土を確実に掻き取って、混練作業をより確実に行うことができる。
【0030】
また、攪拌部材(16)を、回転軸(14)から延出される支持部材(20)と、この支持部材(20)の先端に取り付けられた攪拌羽根(21)とから構成する場合、支持部材(20)の基端部に該支持部材(20)よりも短い長さの第2支持部材(20a)(図5参照)を別途取り付け、この第2支持部材(20a)の先端に第2攪拌羽根(21a)を取り付けることが好ましい。
短い長さの第2支持部材(20a)に第2攪拌羽根(21a)を取り付けたものを回転させることにより、長い支持部材(20)の中途部あたりの汚泥を確実に混練することができる。
尚、第2攪拌羽根(21a)は、攪拌羽根(21)と同様、第2支持部材(20a)の先端に取付角度を変更可能に取り付けられていることが好ましい。
【0031】
次に、この混練機能付き吸引車(1)の使用方法について説明する。
この混練機能付き吸引車(1)においては、混練装置(5)を作動させて使用する場合と、混練装置(5)を作動させないで使用する場合のどちらでも任意に選択することができる。
混練装置(5)を作動させない場合には、通常の吸引車として利用することができる。
【0032】
混練装置(5)を作動させる場合には、まず、汚泥を生じる建設現場へ赴いて真空ポンプ(4)を作動させる。すると、貯留タンク(3)内が減圧されるので、ホース(2)の先端部を汚泥中に挿入することにより、ホース(2)を通じて貯留タンク(3)内に汚泥が吸引され、汚泥が貯留される。
【0033】
所定量の汚泥を貯留したら、真空ポンプ(4)を停止させ、今度は混練装置(5)を作動させる。すると、貯留された汚泥は攪拌羽根(21)によって満遍なく攪拌混練される。従って、運搬中に汚泥の砂や粘土が貯留タンク(3)内底面に堆積することがない。
尚、汚泥貯留後に、セメント投入口(13)からセメントを投入し、その後に混練装置(5)を作動させてもよい。この場合、貯留された汚泥はセメントとともに混練され、汚泥のモルタル化が行われるが、運搬中も混練動作は続けられる。これにより、運搬中にモルタル化汚泥が固化してしまうことがない。
また、混練装置(5)にて混練する際、真空ポンプ(4)を作動させ、排出口(9)を開放し、外部空気で曝気することにより、混練効率が上がる。
【0034】
車両を走行させ、汚泥を排出すべき場所へ到着したら、シリンダ装置(12)を伸長させ、貯留タンク(3)の前側を上げ、ダンプアップ動作を行う。ダンプアップした状態で排出口(9)のバルブを開くと、流動性が良好な汚泥が排出口(9)から勢いよく排出される。
全汚泥の排出を終えたら、排出口(9)のバルブを閉じ、貯留タンク(3)の前側を元の位置まで下げる。
以上により、汚泥の排出作業が完了する。
【0035】
本発明に係る混練機能付き吸引車(1)は、吸引機能と吸引物混練機能の双方を備えるとともに貯留タンク(3)内において回転軸(14)から放射状に複数の攪拌部材(16)を延出させ該攪拌部材(16)を回転軸(14)の軸長方向に沿って相互に間隔をあけて延出させているので、攪拌部材(16)をコンパクトに構成することができ、これにより汚泥状廃棄物の吸引許容容積を大きく確保できるとともに、汚泥固体成分の沈殿防止及びモルタル化汚泥の固化防止を確実に行い、運搬後に吸引汚泥を速やかに排出することができる。
【0036】
尚、本発明に係る混練機能付き吸引車(1)の構成は上記したものに限定されず、以下の構成とすることも可能である。
図6乃至7に示す吸引車(1)と図8乃至9に示す吸引車(1)はいずれも、貯留タンク(3)内に、回転軸(14)が複数本配置されるとともにこれら回転軸(14)が互いに平行に配置され、各回転軸(14)に取り付けられた攪拌部材(16)によって汚泥状廃棄物を混練するように構成されている。また、各回転軸(14)は水平方向に隣り合っている。
図示例では、回転軸(14)の数は2本とされているが、3本以上であってもよい。
【0037】
図6乃至7に示す吸引車(1)では、各回転軸(14)において全ての攪拌部材(16)が回転軸(14)の軸長方向に相互に間隔をあけて取り付けられている。
図8乃至9に示す吸引車(1)では、各回転軸(14)において一部の攪拌部材(16)が回転軸(14)の軸長方向に相互に間隔をあけて取り付けられている。具体的には、2個の攪拌部材(16),(16)が回転軸(14)の軸長方向において同じ箇所に取り付けられ、それら攪拌部材(16),(16)は互いに反対の向きに延出されている。
【0038】
このように貯留タンク(3)内に複数本の回転軸(14)を設け、各回転軸(14)に取り付けられた攪拌部材(16)で攪拌することにより攪拌力を向上させ、回転軸(14)を1本とした場合よりも一層確実に汚泥状廃棄物を満遍なくしかも速やかに攪拌混合することができる。
【0039】
尚、回転軸(14)を複数本とする場合、吸引車(1)は、貯留タンク(3)の下部内面に、図7及び9に示す如く、回転軸(14)と平行に伸びる山部(26)と谷部(25)が連続して形成され、攪拌部材(16)の先端に設けられた攪拌羽根(21)が、隣り合う山部(26)の向かい合う表面とその間の谷部(25)の表面に沿って回転するように構成されることが好ましい。
このような構成とすることにより、攪拌部材(16)は貯留タンク(3)下部の汚泥状廃棄物を全て確実に掻き取ることができる。
【0040】
また、回転軸(14)を複数本とする場合、吸引車(1)は、攪拌部材(16)の先端に設けられた攪拌羽根(21)が、隣の回転軸(14)近傍を通過するように構成されることが好ましい。
このような構成とすることにより、回転軸(14)近傍の汚泥状廃棄物を確実に攪拌混練することができる。
また、隣り合う回転軸(14)は、互いに逆向きに回転駆動されることが好ましい。逆向きに回転させる方が、同じ向きに回転させるよりも満遍なく確実に攪拌混練することができる。
【0041】
また、攪拌部材(16)を、回転軸(14)から延出される支持部材(20)と、この支持部材(20)の先端に取り付けられた攪拌羽根(21)とから構成する場合、攪拌羽根(21)は、貯留タンク内面(山部(26)と谷部(25)を含む)に接触する部分が合成ゴム等の弾性部材から構成され、貯留タンク内面に接触した際にその弾性部分が該内面に沿って変形し得るように構成されていることが好ましい。
【0042】
【発明の効果】
本発明に係る混練機能付き吸引車は、吸引機能と吸引物混練機能の双方を備えるとともに貯留タンク内において回転軸から放射状に複数の攪拌部材を延出させ該攪拌部材を回転軸の軸長方向に沿って相互に間隔をあけて延出させているので、攪拌部材をコンパクトに構成することができ、これにより汚泥状廃棄物の吸引許容容積を大きく確保できるとともに、車両移動中における貯留物の攪拌混練を確実に行い、汚泥固体成分の沈殿防止及びモルタル化汚泥の固化防止を確実に行って、運搬後に吸引汚泥を速やかに排出することができる。また、混練装置を作動させるとともに、真空ポンプの作動及び貯留タンクの一部開放を行って貯留物を曝気することにより、貯留物の攪拌混練効率を更に上げることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a suction wheel with a kneading function. More specifically, the present invention has both a suction function and a suction material kneading function, and a plurality of stirring members are radially extended from a rotating shaft in a storage tank so that the stirring members are rotated. By extending them along the axial length direction, it is possible to secure a large suction capacity and prevent sedimentation of sludge solid components and prevention of solidification of mortar sludge. The present invention relates to a suction wheel with a kneading function that can be discharged.
[0002]
[Prior art]
In various excavation works at the construction site, excavated soil is generated as industrial waste. The earth and sand as industrial waste is transported to a waste disposal site by a truck as it is, or is made into sludge by adding water and sucked by a suction pump car and transported to a waste disposal site.
Sludge is kneaded with cement at the agitation treatment facility at the construction site, and this kneaded product (mortarized sludge) is transported to another construction site by a mixer truck or suction truck, where it is reused as construction materials. Sometimes.
[0003]
[Problems to be solved by the invention]
