Description
本発明は、タンククリーニング装置に関する。タンカーは一航海ごとに、タンク内に異なる種類の積荷（石油製成油、医薬品及び動植物の食物油など）を積み込むことがあり、そのように積荷が変われば、タンク内を洗浄しなければならない（非特許文献１）。本発明は、このようなタンカーのタンク内を洗浄するタンククリーニング装置に関する。 The present invention relates to a tank cleaning device. Tankers may load different types of cargo (petroleum oil, pharmaceuticals, animal and plant food oils, etc.) in the tank on each voyage, and if the load changes, the tank must be cleaned. (Non-Patent Document 1). The present invention relates to a tank cleaning apparatus for cleaning the inside of a tank of such a tanker.
タンカーのタンクは船体中に区画して複数カ所設けられるが、図４に示すように、各タンクＴの側壁は、波板状の隔壁Ｗで囲まれている。タンク内を洗浄する場合は、平坦な天面や底面だけでなく、波板状の隔壁も完全に洗浄しなければならないため、隔壁Ｗの傾斜面にも洗浄水を有効に噴射しなければならない。このため、クリーニング装置Ｃの設置位置は、隔壁Ｗの全ての面に有効に洗浄水を噴射しうる数カ所に必然的に決められてしまう。図４中の符号Ｃはそのような設置位置を示している。 The tanker tanks are divided into a hull and provided at a plurality of locations. As shown in FIG. 4, the side walls of the tanks T are surrounded by corrugated partition walls W. When cleaning the inside of the tank, not only the flat top and bottom surfaces, but also the corrugated partition walls must be cleaned completely, so the cleaning water must be effectively sprayed onto the inclined surfaces of the partition walls W. . For this reason, the installation positions of the cleaning device C are inevitably determined at several places where the cleaning water can be effectively sprayed on all surfaces of the partition wall W. A symbol C in FIG. 4 indicates such an installation position.
ところで、クリーニング装置Ｃの従来例は、つぎのように構成されている。
図５において、１はタンク上面の上甲板、２はマンホール状の架台である。クリーニング装置Ｃは、架台２上に着脱自在に取付けられる駆動部１０とタンクＴ内に挿入される洗浄部２０とからなる。駆動部１０の取水パイプ１８に水が供給されると、その水流が連結筒２１を通って下方に送られ、噴射ノズル２３を水平軸まわりに回転させながら、複数個のノズル口から洗浄水を噴射させる。この噴射洗浄水によりタンク内壁面が洗浄される。同時に、噴射ノズル２３が支持された旋回筒２２が垂直軸まわりに旋回するので、タンク内壁面が１ヵ所だけでなく、３６０°全周にわたって洗浄されることになる。
Incidentally, the conventional example of the cleaning device C is configured as follows.
In FIG. 5, 1 is an upper deck of the tank upper surface, and 2 is a manhole-shaped mount. The cleaning device C includes a drive unit 10 that is detachably mounted on the gantry 2 and a cleaning unit 20 that is inserted into the tank T. When water is supplied to the intake pipe 18 of the drive unit 10, the water flow is sent downward through the connecting cylinder 21, and the cleaning water is supplied from a plurality of nozzle ports while rotating the injection nozzle 23 around the horizontal axis. Let spray. The inner wall surface of the tank is cleaned with this jet cleaning water. At the same time, the swivel cylinder 22 on which the injection nozzle 23 is supported revolves around the vertical axis, so that the tank inner wall surface is cleaned not only at one place but also around 360 °.
ところで、上記従来例には、つぎのような問題がある。
図６において、３はタンクＴの底板である内底板、４は外板である。５は上甲板１の上面に配設されているパイプやグレーチング等の艤装品である。
クリーニング装置ＣはタンクＴの隔壁の傾斜面も完全に洗浄しなければならないことから、水平面内の設置位置が固定化されるので、その上面にパイプやグレーチング等の艤装品５が存在することがある。この場合、クリーニング装置Ｃの保守点検のため、上方に抜出すことを考慮すると、クリーニング装置Ｃの長さを短くしなければならない。そうすると、クリーニング装置Ｃの噴射ノズル２３の位置は、タンクＴ内の上面から略１／３位になり、タンクＴの底面３には遠くなる。このため、タンク下方の洗浄力が弱くなる。
また、いくらクリーニング装置Ｃの長さが短くても、上甲板１と艤装品５との間隔ＣＨよりは長いので、クリーニング装置Ｃを上方に抜出す作業には、困難が伴う。あるいは、これを回避しようとすれば、パイプやグレーチングを迂回させることになるが、そうすると他の艤装品と干渉したり、パイプ内の輸送抵抗が大きくなる等の問題が生じる。
Incidentally, the above conventional example has the following problems.
In FIG. 6, 3 is an inner bottom plate which is a bottom plate of the tank T, and 4 is an outer plate. Reference numeral 5 denotes fittings such as pipes and gratings disposed on the upper surface of the upper deck 1.
Since the cleaning device C must completely clean the inclined surface of the partition wall of the tank T, the installation position in the horizontal plane is fixed, so that fittings 5 such as pipes and gratings may exist on the upper surface. is there. In this case, the length of the cleaning device C must be shortened considering that the cleaning device C is pulled out for maintenance and inspection. Then, the position of the spray nozzle 23 of the cleaning device C is about 1/3 from the top surface in the tank T, and is far from the bottom surface 3 of the tank T. For this reason, the cleaning power below the tank is weakened.
Further, no matter how short the cleaning device C is, it is longer than the distance CH between the upper deck 1 and the fitting 5, so that it is difficult to extract the cleaning device C upward. Alternatively, if this is to be avoided, pipes and gratings will be bypassed, but doing so will cause problems such as interference with other fittings and increased transport resistance within the pipe.
本発明は上記事情に鑑み、上甲板上の艤装品と干渉することなくタンクから抜出せ、かつタンク内に深く挿入して隅々まで有効に水噴射できるタンクのクリーニング装置を提供することを目的とする。 SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has an object to provide a tank cleaning device that can be removed from a tank without interfering with the fittings on the upper deck, and can be inserted deeply into the tank and effectively sprayed water to every corner. And
第１発明のタンククリーニング装置は、タンク上面の架台に着脱自在に取付けられる駆動部と、タンク内に挿入される洗浄部とからなり、前記洗浄部は、長尺円筒状の連結筒と、該連結筒の下端に、垂直軸まわりに旋回自在に取付けられた旋回筒と、該旋回筒に、水平軸まわりに回転自在に取付けられた噴射ノズルとからなり、前記連結筒は、軸方向に２以上に分割可能に結合されていることを特徴とする。

図１は、本発明の第１実施形態に係るクリーニング装置Ｃの説明図である。
同図において、１はタンク上面の上甲板、２はマンホール状の架台である。クリーニング装置Ｃは、架台２に着脱自在に取付けられる駆動部１０とタンク内に挿入される洗浄部２０とからなる。
前記駆動部１０は、ケーシング１１とギヤボックス１２とからなり、ギヤボックス１２中には減速歯車列１３からなる旋回機構が入れられている。そして、入側の歯車の回転軸１４と、出側の歯車の回転軸１５はケーシング１１側に突出しており、前者の回転軸１４にはインペラ１６が取付けられており、後者の回転軸１５にはカップリング１７が取付けられている。ケーシング１１には取水パイプ１８が形成されて、外部から洗浄水が導入されるようになっている。取水パイプ１８はケーシング１１内で２本の通路に分かれており、一方の通路には前記インペラ１６が挿入されており、他方の通路には開閉弁１９が介装されている。
Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram of a cleaning device C according to the first embodiment of the present invention.
In the figure, 1 is an upper deck of the tank upper surface, and 2 is a manhole-shaped mount. The cleaning device C includes a drive unit 10 that is detachably attached to the gantry 2 and a cleaning unit 20 that is inserted into the tank.
The drive unit 10 includes a casing 11 and a gear box 12, and a turning mechanism including a reduction gear train 13 is placed in the gear box 12. The rotating shaft 14 of the incoming gear and the rotating shaft 15 of the outgoing gear protrude toward the casing 11, and an impeller 16 is attached to the former rotating shaft 14. A coupling 17 is attached. A water intake pipe 18 is formed in the casing 11 so that cleaning water is introduced from the outside. The intake pipe 18 is divided into two passages in the casing 11. The impeller 16 is inserted into one passage, and an opening / closing valve 19 is interposed in the other passage.
前記洗浄部２０は、長尺円筒状の連結筒２１と、その下端に回転自在に結合された旋回筒２２と、その旋回筒２２の前端で回転する噴射ノズル２３とからなる。連結筒２１の上端には大径フランジ21f が形成されており、この大径フランジ21f が架台２上にボルト等で着脱自在に取付けられている。またケーシング１１の下端は、連結筒２１の大径フランジ21f にボルト等で着脱自在に結合されている。そして、連結筒２１の下端に取付けられた旋回筒２２には、旋回軸２４が取付けられている。この旋回軸２４の上端は、前記ギヤボックス１２から延びた回転軸１５にカップリング１７を介して連結されている。噴射ノズル２３は連結筒２１内と旋回筒２２内を通ってきた水流によって旋回しながら、その先端から水を放射状に噴射するものである。 The cleaning unit 20 includes a long cylindrical connecting cylinder 21, a revolving cylinder 22 rotatably coupled to the lower end thereof, and an injection nozzle 23 that rotates at the front end of the revolving cylinder 22. A large-diameter flange 21f is formed at the upper end of the connecting cylinder 21, and the large-diameter flange 21f is detachably attached to the mount 2 with bolts or the like. The lower end of the casing 11 is detachably coupled to the large-diameter flange 21f of the connecting cylinder 21 with a bolt or the like. A turning shaft 24 is attached to the turning cylinder 22 attached to the lower end of the connecting cylinder 21. The upper end of the turning shaft 24 is connected to a rotating shaft 15 extending from the gear box 12 via a coupling 17. The spray nozzle 23 sprays water radially from the tip of the spray nozzle 23 while swirling by the water flow that has passed through the connecting tube 21 and the swivel tube 22.
前記駆動部１０の取水パイプ１８から水が供給されるとインペラ１６が回転し、その回転が歯車列１３を介して旋回軸２４を回転させ、旋回筒２２を垂直軸まわりで回転させる。
一方、開閉弁１９を経て、ケーシング１１から連結筒２１の内部を経て旋回筒２２の内部へ供給された水は、噴射ノズル２３を水平軸まわりで回転させながら、ノズル口から水流を噴射する。この噴射水は垂直面内で放射状に飛び、かつ噴射方向が旋回筒２２により３６０°連続変化するので、タンクＴの隔壁Ｗや底面、天面を洗浄することができる。また、この噴射水は水平面内でも旋回するので、タンクＴ内の全面を洗浄することができる。
When water is supplied from the intake pipe 18 of the drive unit 10, the impeller 16 rotates, and the rotation rotates the swivel shaft 24 via the gear train 13 and the swivel cylinder 22 rotates around the vertical axis.
On the other hand, the water supplied from the casing 11 to the inside of the swivel cylinder 22 via the opening / closing valve 19 and the inside of the connecting cylinder 21 injects a water flow from the nozzle opening while rotating the injection nozzle 23 around the horizontal axis. The jet water radiates radially in the vertical plane, and the jet direction continuously changes by 360 ° by the swivel cylinder 22, so that the partition wall W, the bottom surface, and the top surface of the tank T can be washed. Further, since the jet water swirls in a horizontal plane, the entire surface in the tank T can be washed.
本実施形態の特徴は、連結筒２１と旋回軸２４を軸方向に分割可能に結合した点に存する。そこで、この点を以下に詳述する。
図１に示す実施形態では、前記連結筒２１は、３個の筒体21A,21B,21C からなり、各筒体はフランジ２６で着脱自在に結合されている。なお、上端の筒体21A の上端には前記大径フランジ21f が形成されている。また、下端の筒体21C には旋回筒２２がフランジ２６で着脱自在に結合されている。
The feature of this embodiment resides in that the connecting cylinder 21 and the turning shaft 24 are coupled so as to be split in the axial direction. Therefore, this point will be described in detail below.
In the embodiment shown in FIG. 1, the connecting cylinder 21 includes three cylinders 21A, 21B, and 21C, and each cylinder is detachably coupled by a flange 26. The large diameter flange 21f is formed at the upper end of the upper end cylindrical body 21A. In addition, a revolving cylinder 22 is detachably coupled to the lower end cylinder 21C by a flange 26.
前記旋回軸２４も、３本の軸体24A,24B,24C からなり、各軸体はピン２７で着脱自在に結合されている。なお、上端の軸体24A は既述のごとく、ギヤボックス１２から下方に出ている回転軸１５にカップリング１７で着脱自在に連結され、下端の軸体24C は旋回筒２２の取付軸２８に着脱自在に連結されている。 The pivot shaft 24 is also composed of three shaft bodies 24A, 24B, 24C, and each shaft body is detachably coupled by a pin 27. As described above, the upper end shaft body 24A is detachably connected to the rotary shaft 15 protruding downward from the gear box 12 by the coupling 17, and the lower end shaft body 24C is connected to the mounting shaft 28 of the swivel cylinder 22. Removably connected.

FIG. 2 is an explanatory diagram of the separation / extraction operation of the cleaning device C according to the first embodiment.
With reference to this figure, the operation of extracting the cleaning device C from the tank T will be described.
(1) The drive unit 10 is removed.
The drive unit 10 can be separated by removing the casing 11 from the large-diameter flange 21f of the connecting shaft 21A.
The rotating shaft 15 is separated from the shaft body 24A of the turning shaft 24 by a coupling 17. The cleaning unit 20 remains inserted in the tank T.
(2) The connecting cylinder 21 is pulled up again, and the cylinder 21A at the upper end and the shaft body 24A are separated. The cylinder 21A can be separated by a flange, and the shaft 24A can be separated by a pin.
(3) The connecting cylinder 21 is further pulled up, and the intermediate cylinder 21B and the shaft 24B are separated. Also in this case, the cylindrical body 21B can be separated by a flange, and the shaft body 24B can be separated by a pin.
(4) Finally, the cylinder 21C and the shaft 24C at the lower end are pulled up. The swivel cylinder 22 and the injection nozzle 23 may be pulled out together.
上記のように長尺物の連結筒２１と旋回軸２４を３分割できるようにしているので、クリーニング装置Ｃを段階的に洗浄部をタンク内から出していけ、しかも各段階の引き上げ量は少なくてすむので、上甲板上面の艤装品と干渉することがない。よって、艤装品との干渉を考慮せず、クリーニング装置の設置位置を決められるので、少ない設置数で、有効にタンク洗浄が行える。また、洗浄部の長さを引き抜きの都合で制約されないので、タンク内洗浄に最適の長さに延長でき、洗浄効果を高めることができる。 Since the long connecting cylinder 21 and the pivot shaft 24 can be divided into three parts as described above, the cleaning unit C can be taken out of the tank step by step, and the amount of lifting at each stage is small. As a result, it does not interfere with the fittings on the upper deck. Therefore, since the installation position of the cleaning device can be determined without considering interference with the fitting, tank cleaning can be performed effectively with a small number of installations. In addition, since the length of the cleaning section is not restricted by the convenience of pulling out, it can be extended to an optimum length for cleaning in the tank, and the cleaning effect can be enhanced.
図３は、本発明の第２実施形態に係るクリーニング装置Ｃの説明図である。
この実施形態は、連結筒２１を２本の筒体21A,21C で構成し、旋回軸２４を２本の軸体24A,24C で構成したものである。この実施形態においても、長尺物の連結筒２１と旋回軸２４を２分割して引き出せるので、前記実施形態と同様の効果を奏する。

In this embodiment, the connecting cylinder 21 is constituted by two cylinders 21A and 21C, and the turning shaft 24 is constituted by two axis bodies 24A and 24C. Also in this embodiment, since the long connecting cylinder 21 and the turning shaft 24 can be pulled out in two, the same effect as the above embodiment can be obtained.
上記に連結筒２１と旋回軸２４を３分割した例と２分割した例を説明したが、４分割以上に構成してもよく、そのような実施形態も本発明に含まれるものである。 The example in which the connecting cylinder 21 and the turning shaft 24 are divided into three parts and the example in which the connecting cylinder 21 and the turning shaft 24 are divided into two parts have been described above. However, the connecting cylinder 21 and the turning shaft 24 may be divided into four parts or more.
