Description

本考案は、化学合成における重合缶、反応缶、発酵における発酵槽等の各種タンクの内壁面に高圧水を噴射して洗浄するタンク内洗浄装置に関する。   The present invention relates to an in-tank cleaning apparatus that injects high-pressure water onto inner walls of various tanks such as polymerization cans, reaction cans, and fermenters for fermentation in chemical synthesis.

近年の重合缶、反応缶、発酵槽等には、タンク内壁を洗浄するための洗浄専用のノズルをそのタンクの上部構造に備えているものが多い。しかし、従来からの既設のタンクは、洗浄専用ノズルを備えておらず、このような洗浄専用ノズルを備えない既設のタンク内を洗浄するための洗浄装置が提案されている（例えば、特許文献１参照）。   Many recent polymerization cans, reaction cans, fermenters, and the like are equipped with a nozzle dedicated to cleaning the inner wall of the tank in the upper structure of the tank. However, a conventional existing tank does not include a cleaning nozzle, and a cleaning apparatus for cleaning the existing tank that does not include such a cleaning nozzle has been proposed (for example, Patent Document 1). reference).

具体的には「スライドランス」と称される伸縮、旋回、及び俯仰の各動作が可能な竿状部材と、この竿状部材の先端部に取付けられたノズルヘッドと、このノズルヘッドにタンク内を洗浄する高圧水を供給する高圧水発生手段とを備え、竿状部材の先端部のノズルヘッドは、竿状部材の先端部から昇降し、竿状部材の本体の周囲を公転しつつ自転させて高圧水を噴射する。このような洗浄装置によって、内部に複雑な構造物を備えたタンクに対しても容易にその内部の洗浄を行うことができるものである。   Specifically, a saddle-shaped member called “sliding lance” capable of extending, contracting, turning, and raising / lowering, a nozzle head attached to the tip of the saddle-shaped member, and the nozzle head in the tank And a high pressure water generating means for supplying high pressure water for cleaning the nozzle head, the nozzle head at the tip of the bowl-shaped member is raised and lowered from the tip of the bowl-like member and revolves around the body of the bowl-like member while revolving. High pressure water. Such a cleaning apparatus can easily clean the inside of a tank having a complicated structure inside.

しかしながら、近年の重合缶、反応缶、発酵槽等は、タンク内に投入する材料、材質等によって、付属装置等による多種多様な内部形状を有するタンクが存在するに至っている。図５は従来の直管型のスライドランスを用いた際の撹拌羽根及びバッフル板を備えたタンク平面の干渉の状態を説明する説明図である。   However, recent polymerization cans, reaction cans, fermenters, and the like have come to have tanks having various internal shapes depending on the materials, materials, and the like put into the tank. FIG. 5 is an explanatory view for explaining an interference state of a tank plane provided with a stirring blade and a baffle plate when a conventional straight pipe type slide lance is used.

図は一般的な反応缶や発酵槽で用いられるタンクの平面図を示している。タンク５０の軸心には撹拌羽根を回動する回動軸５３が配置され、タンク５０の側壁に沿って複数個のバッフル板（邪魔板）５２が配置されている。直管型ランス５５はタンク５０のマンホール５１から挿入され、マンホール５１を中心にして駆動させたとしても、マンホール５１に近接するバッフル板５２に干渉してバッフル板５２の間隙Ａに進入することができずこの間隙Ａが洗浄不可域となる。また、回動軸５３の干渉により、マンホール５１に対向する位置に進入することが難しく、この対向位置Ｂが洗浄不可域となる。   The figure has shown the top view of the tank used with a general reaction can and a fermenter. A rotation shaft 53 for rotating the stirring blade is disposed at the axis of the tank 50, and a plurality of baffle plates (baffle plates) 52 are disposed along the side wall of the tank 50. Even if the straight tube type lance 55 is inserted from the manhole 51 of the tank 50 and driven around the manhole 51, it can interfere with the baffle plate 52 adjacent to the manhole 51 and enter the gap A of the baffle plate 52. This gap A cannot be cleaned. Further, it is difficult to enter the position facing the manhole 51 due to the interference of the rotating shaft 53, and the facing position B becomes a non-cleanable area.

尚、図５は回転羽根とバッフル板とを備えたタンクの場合を説明したが、例えば、粘性を有するゴム系樹脂等の重合缶においては、複数の反応を時間をおいて行うことを想定して、タンク内部への投入口を複数個備えるために、タンク内部において複雑な形状を有するものもあり、洗浄に際して死角となる箇所、即ち、洗浄不可域が更に多く存在するに至っている。   Note that FIG. 5 illustrates the case of a tank provided with rotating blades and a baffle plate. For example, in a polymerization can such as a rubber-based resin having viscosity, it is assumed that a plurality of reactions are performed with time. In order to provide a plurality of inlets to the inside of the tank, some tanks have a complicated shape inside the tank, and there are more spots that become blind spots in cleaning, that is, areas that cannot be cleaned.

以上のように、洗浄に際して、スライドランスと、タンク内の撹拌翼、バッフル板等が干渉してしまう箇所があり、洗浄が困難となり、収容する材料に悪影響を及ぼしていた。更に、複雑形状を有する箇所に対して手動洗浄を行う場合には、タンク内作業は酸欠、高圧洗浄の危険があり、作業者の安全性の確保を充分にする必要もある。   As described above, there are places where the slide lance, the stirring blades in the tank, the baffle plate, and the like interfere with each other during cleaning, which makes cleaning difficult and adversely affects the material to be stored. Furthermore, when manual cleaning is performed on a portion having a complicated shape, there is a risk of lack of oxygen and high-pressure cleaning in the tank operation, and it is necessary to ensure the safety of the operator.

本考案は、上記課題を鑑み、複雑形状を有するタンク内部であっても死角領域を適切に洗浄することができるタンク内洗浄装置を提供するものである。   In view of the above problems, the present invention provides an in-tank cleaning apparatus capable of appropriately cleaning a blind spot region even inside a tank having a complicated shape.

本考案のタンク内洗浄装置は、高圧水発生手段から供給される高圧洗浄水を所望の方向に噴射するノズルヘッドと、このノズルヘッドを先端部に保持し、該先端部を前記タンク内に挿入可能な竿状部材と、ノズルヘッドに高圧水を供給しつつ竿状部材の先端部から所望の高さ位置に吊り下げるホース送り手段と、竿状部材を水平及び俯仰動作して、前記ノズルヘッドをタンク内壁に沿って移動させる竿状部材駆動手段とを備えるものである。   The tank cleaning apparatus of the present invention includes a nozzle head that sprays high pressure cleaning water supplied from high pressure water generating means in a desired direction, and the nozzle head is held at the tip, and the tip is inserted into the tank. And a nozzle hose feeding means for suspending the hook-like member horizontally and up and down by supplying a high-pressure water to the nozzle head while suspending the hook-like member to a desired height position. And a hook-like member driving means for moving the pipe along the inner wall of the tank.

これにより、竿状部材の先端部をタンク上部のマンホールから挿入し、竿状部材の先端部を洗浄されるタンク内壁面に近接させた上で、ホース送り手段により、ノズルヘッドを垂直方向に下降・上昇させつつ高圧水を噴射させることにより、タンク上下方向に亘って高圧水噴射洗浄を行うことができる。   As a result, the tip of the bowl-shaped member is inserted from the manhole at the top of the tank, the tip of the bowl-shaped member is brought close to the inner wall surface of the tank to be cleaned, and the nozzle head is lowered vertically by the hose feed means. -By jetting high-pressure water while raising, high-pressure water jet cleaning can be performed across the tank in the vertical direction.

本考案では、竿状部材の先端部近傍が、曲折した曲折部を備え、竿状部材を軸心周りに回転させる軸回転手段を更に備えることにより、撹拌羽根の回動軸を介したマンホールの対向領域や、マンホールの両側方のバッフル板の陰になっている領域等の従来では干渉していた洗浄が不能であった領域についても、その近傍まで先端部を竿状部材の先端部をそれら領域に進入させることができるため、洗浄不可域が存在しなくなり、複雑形状を有するタンク内部の全ての領域を洗浄することが可能となる。   In the present invention, the vicinity of the tip of the bowl-shaped member is provided with a bent portion, and further provided with a shaft rotating means for rotating the bowl-shaped member around the axis, so that the manhole via the rotating shaft of the stirring blade is provided. For the areas that could not be cleaned in the past, such as the facing area and the area behind the baffle plates on both sides of the manhole, the tip should be placed near the tip of the bowl-shaped member. Since it is possible to enter the region, there is no non-cleanable region, and it is possible to clean all the regions inside the tank having a complicated shape.

本考案の竿状部材は、先端部にノズルヘッドを備え、ノズルヘッドを備えた先端部の手前で曲折された曲折部を備えれば良い。材質としては、鉄、アルミニウム等の金属製やグラスファイバー製等の長尺な線材や長管、入れ子式に伸長可能な管等が選択される。この竿状部材は竿状部材駆動手段によって、タンク内に挿入、俯仰及び水平の各動作を可能とするように構成される。   The hook-shaped member of the present invention may be provided with a nozzle head at the tip, and a bent portion that is bent before the tip provided with the nozzle head. As the material, a long wire rod or long tube made of metal such as iron or aluminum or glass fiber, a tube that can be telescopically extended, or the like is selected. The hook-shaped member is configured to be capable of being inserted into the tank, upright, and horizontal by the hook-shaped member driving means.

また、本考案の竿状部材駆動手段は、竿状部材を水平及び俯仰動作して、前記ノズルヘッドをタンク内壁に沿って移動させるものであればよく、好ましくは、タンク上部のマンホールを覆う基台を貫く支点を備え、この支点の竿状部材の後端側に竿状部材の長さ方向に挿入駆動する挿入駆動手段と、同じく竿状部材の後端側を俯仰方向及びこの俯仰状態のまま旋回駆動することにより、前記支点を頂点とする円錐空間内を駆動するものが挙げられる。   Further, the hook-like member driving means of the present invention may be any means as long as the hook-like member is moved horizontally and up and down to move the nozzle head along the inner wall of the tank. An insertion driving means for inserting and driving in the longitudinal direction of the hook-like member on the rear end side of the hook-like member of the hook, and the rear end side of the hook-like member in the raising and lowering direction. One that drives in a conical space with the fulcrum at the apex is provided by turning and driving as it is.

竿状部材の曲折部はマンホールへの挿入の邪魔とならず、タンク内部の全ての領域を洗浄することが可能であれば、その曲折の角度等は何ら制限されるものではない。少なくとも、タンク内の回転羽根を回転させる回動軸を避けて、マンホールの対向位置のタンク内壁面近傍にノズルヘッドを進入させる程度に曲折されていれば良い。また、可能であるならば、曲折部を蛇腹状等の可動として先端部をワイヤで連結してこのワイヤを伸縮させる等として曲折部の角度を変化させる等のように、曲折の度合いを変化させる機能を備えても良い。   The bent portion of the hook-shaped member does not interfere with the insertion into the manhole, and the angle of the bent is not limited as long as it can clean the entire area inside the tank. It is sufficient that the nozzle head is bent to the extent that the nozzle head enters the vicinity of the inner wall surface of the tank at a position opposite to the manhole, avoiding at least the rotating shaft that rotates the rotating blades in the tank. If possible, change the degree of bending, such as changing the angle of the bent part by connecting the tip part with a wire by moving the bent part in a bellows-like shape and expanding and contracting the wire. A function may be provided.

本考案のホース送り手段は、竿状部材の先端部のノズルヘッドに高圧水を供給する機能と、ノズルヘッドを竿状部材の先端部から吊下させてノズルヘッドを上下方向に昇降させ、任意の高さ位置に停止させるものであれば良い。例えば、ノズルヘッドを吊下させるワイヤと高圧水を供給するホースとを個別に配しても良いが、高圧水を内部の通路で供給するホース部材自体でノズルヘッドを吊下させるものの方が取り回しに優れ、作業性が良い。この場合、ノズルヘッドを上下方向に昇降させ、任意の高さ位置に停止させるためにホース送り手段でホース部材を排出・巻き取るリールを駆動・停止することにより行われる。   The hose feeding means of the present invention has a function of supplying high-pressure water to the nozzle head at the tip of the bowl-shaped member, and the nozzle head is raised and lowered in the vertical direction by hanging the nozzle head from the tip of the bowl-like member. What is necessary is just to stop at the height position. For example, a wire for suspending the nozzle head and a hose for supplying high-pressure water may be separately arranged, but a hose member itself for supplying high-pressure water through an internal passage itself is used for handling. Excellent workability. In this case, the nozzle head is moved up and down to drive and stop the reel that discharges and winds the hose member by the hose feed means in order to stop the nozzle head at an arbitrary height position.

本考案のノズルヘッドは、高圧水発生手段から供給される高圧洗浄水を噴射ノズルにより所望の方向に噴射するものであれば良い。特に、高圧水の噴射ノズルを水平方向に交差する方向に回転させるものであれば、ホース送り手段による昇降運動と共に行うことにより、昇降方向に沿って良好にタンク内壁面を洗浄することができる。また、噴射ノズルはノズルヘッドに１つ以上備えておればよく、噴射ノズルが回転されるものであれば、噴射ノズルの回転軸に対して、２つ以上の均等な角度に配されれば良い。   The nozzle head of the present invention is not limited as long as the high-pressure washing water supplied from the high-pressure water generating means is jetted in a desired direction by the jet nozzle. In particular, if the high-pressure water injection nozzle is rotated in a direction crossing the horizontal direction, the inner wall surface of the tank can be cleaned well along the up-and-down direction by performing the up-and-down movement by the hose feeding means. In addition, one or more injection nozzles may be provided in the nozzle head, and as long as the injection nozzle is rotated, it may be arranged at two or more equal angles with respect to the rotation axis of the injection nozzle. .

更に、竿状部材駆動手段により、竿状部材を水平及び俯仰動作して、前記ノズルヘッドをタンク内壁に沿って移動させ、竿状部材の曲折部と軸回転手段とを組合せることにより、ノズルヘッドをタンク内壁に沿って移動させることができるため、より複雑な形状を有するタンク内部の全ての領域を洗浄することが可能となる。   Further, the hook-shaped member is moved horizontally and up and down by the hook-shaped member driving means, the nozzle head is moved along the inner wall of the tank, and the bent portion of the hook-shaped member and the shaft rotating means are combined to form a nozzle. Since the head can be moved along the inner wall of the tank, it is possible to clean all areas inside the tank having a more complicated shape.

更に好ましくは、高圧水の噴射ノズルを水平方向に交差する方向に回転させ、尚且つ、水平方向に回転させるノズルヘッドでは、複雑な形状を有するタンク内部の全ての領域を洗浄することが可能となることは当然であるが、同じタンク内壁面の被洗浄領域に対して、様々な角度から高圧水を噴射させることができ、洗浄ムラが解消されるものとなる。   More preferably, the nozzle head that rotates the injection nozzle of the high-pressure water in the direction intersecting the horizontal direction and rotates in the horizontal direction can wash all areas inside the tank having a complicated shape. As a matter of course, high-pressure water can be sprayed from various angles to the area to be cleaned on the same inner wall surface of the tank, and cleaning unevenness can be eliminated.

本考案のタンク内洗浄装置のノズルヘッドの移動操作は、手動でも自動でも何れでも良い。手動で行う場合には、ランスの伸長長さや各ユニットの回転角度を計測しながら行っても良いし、ノズルヘッド等にカメラを搭載させて目視で行っても良い。また、自動で行う場合には、エンコーダによる位置制御で洗浄シーケンスに従い、目的部を洗浄する。   The operation of moving the nozzle head of the in-tank cleaning apparatus of the present invention may be either manual or automatic. When performing manually, it may be performed while measuring the extension length of the lance and the rotation angle of each unit, or may be performed visually by mounting a camera on a nozzle head or the like. In the case of automatic operation, the target part is cleaned according to the cleaning sequence by position control by the encoder.

何れの場合でも、ホース部材の送出量を計測して、ノズルヘッドの高さ位置を計測して、昇降させつつ高圧水洗浄を行えば良い。   In any case, it is only necessary to measure the delivery amount of the hose member, measure the height position of the nozzle head, and perform high-pressure water washing while moving up and down.

FIG. 2 is a front view showing the mounting of the tank cleaning apparatus of FIG. 1 on the tank. FIG. 3 is a plan view showing the mounting of the tank cleaning apparatus of FIG. 1 on the tank. FIG. 4 is an explanatory diagram illustrating the configuration of the main part of FIG.

図に示す通り、本考案のタンク内洗浄装置１０は、タンク３０上部のマンホール３１に装着可能な基台１１と、この基台１１の中心を遊貫する竿状部材としての円管で構成されたランス１２とを備える。ランス１２の先端部には高圧洗浄水を噴射する２本の噴射ノズル２１を備えたノズルヘッド２０が備わり、ノズルヘッド２０の後端側に曲折部１３が形成されている。   As shown in the figure, the in-tank cleaning apparatus 10 of the present invention is composed of a base 11 that can be mounted in a manhole 31 above the tank 30 and a circular tube as a bowl-shaped member that passes through the center of the base 11. The lance 12 is provided. The tip of the lance 12 is provided with a nozzle head 20 having two injection nozzles 21 for injecting high-pressure washing water, and a bent portion 13 is formed on the rear end side of the nozzle head 20.

基台１１には、タンク３０に挿入されたランス１２を基台の中心を支点として約３０°俯仰させる俯仰ユニット１４と、この俯仰ユニット１４自体を±１８０°旋回させる旋回ユニット１５とを備える。この俯仰ユニット１４と旋回ユニット１５とを協動させることにより、ランス１２を基台１１の支点を頂点とする円錐空間内で動作できる。   The base 11 includes an elevation unit 14 that raises the lance 12 inserted into the tank 30 about 30 ° with the center of the base as a fulcrum, and a turning unit 15 that turns the elevation unit 14 itself ± 180 °. By cooperating the raising and lowering unit 14 and the turning unit 15, the lance 12 can be operated in a conical space having the fulcrum of the base 11 as a vertex.

これに加えて、基台１１には、タンク３０に挿入されたランス１２のタンク３０内進入長さを調整するランススライドユニット１６と、軸回転手段としてランス１２をランスの軸心を中心として回転させるランス回転ユニット１７と、ホース送り手段としてのホース送りユニット１８とを更に備える。   In addition to this, the base 11 includes a lance slide unit 16 that adjusts the length of the lance 12 inserted into the tank 30 into the tank 30 and a lance 12 that rotates as a shaft rotating means around the axis of the lance. A lance rotating unit 17 to be operated and a hose feeding unit 18 as hose feeding means are further provided.

これにより、ランス１２先端部のノズルヘッド２０は、タンク３０上部のマンホール３１から挿入され、基台１１の中心を支点として、俯仰ユニット１４と旋回ユニット１５とランススライドユニット１６とにより、洗浄されるタンク内壁面に近接させることができる。また、従来は撹拌羽根の回動軸３３に干渉してノズルヘッドが届かなかったマンホールの対向領域については、ランス１２の曲折部１３とランス回転ユニット１７とにより、回動軸３３を避けてノズルヘッド２０を近接させることができる。   As a result, the nozzle head 20 at the tip of the lance 12 is inserted from the manhole 31 at the top of the tank 30 and is cleaned by the elevation unit 14, the turning unit 15, and the lance slide unit 16 with the center of the base 11 as a fulcrum. It can be brought close to the inner wall surface of the tank. Further, in the conventional manhole facing area where the nozzle head does not reach due to interference with the rotating shaft 33 of the stirring blade, the bent portion 13 of the lance 12 and the lance rotating unit 17 avoid the rotating shaft 33 and avoid the nozzle. The head 20 can be brought close.

また、マンホール３１の両側方のバッフル板３２の陰になっている領域については、曲折部１３と俯仰ユニット１４と旋回ユニット１５とランススライドユニット１６とランス回転ユニット１７とを組み合わせ、ノズルヘッド２０をバッフル板３２の陰になっていた領域に近接させることができる。このように、タンク内壁面に近接させたノズルヘッド２０は高圧洗浄水を噴射する２本の噴射ノズル２１で壁面を洗浄する。   Further, in the area behind the baffle plates 32 on both sides of the manhole 31, the bent portion 13, the elevation unit 14, the turning unit 15, the lance slide unit 16, and the lance rotating unit 17 are combined, and the nozzle head 20 is installed. It can be brought close to the area behind the baffle plate 32. Thus, the nozzle head 20 brought close to the inner wall surface of the tank cleans the wall surface with the two injection nozzles 21 that inject high-pressure cleaning water.

更に、ランス１２の先端部のノズルヘッド２０は、ホース送りユニット１８によって出入り可能なホース部材１９で連結され、ランス１２の先端部のロックを解除した後に、ホース送りユニット１８でホース部材１９を先端部方向に送り出すと、ランス１２の先端部から吊下され、タンク３０内を降下する。ホース送りユニット１８を停止させれば、ノズルヘッド２０は任意の高さ位置で停止する。ホース部材１９を引き込めば、ノズルヘッド２０は上昇する。このホース送りユニット１８により、ノズルヘッドを垂直方向に下降・上昇させつつ高圧水を噴射させることにより、タンク上下方向に亘って高圧水噴射洗浄を行うことができる。   Further, the nozzle head 20 at the tip of the lance 12 is connected by a hose member 19 that can be moved in and out by the hose feed unit 18, and after unlocking the tip of the lance 12, the hose member 19 is moved to the tip by the hose feed unit 18. When it is sent out partly, it is suspended from the tip of the lance 12 and descends in the tank 30. If the hose feed unit 18 is stopped, the nozzle head 20 stops at an arbitrary height position. When the hose member 19 is retracted, the nozzle head 20 rises. The hose feed unit 18 can perform high-pressure water jet cleaning in the vertical direction of the tank by jetting high-pressure water while lowering and raising the nozzle head in the vertical direction.

尚、ノズルヘッド２０の噴射ノズル２１は、３０ＭＰａの圧で１７０Ｌ／ｍｉｎで高圧水を噴射させるため、近接するタンク内壁面は勿論のこと、干渉するものがなければ比較的遠くの壁面であっても良好に高圧洗浄することが可能である。このため、干渉が少ない噴射領域を選択することにより、広い領域を洗浄することが可能となる。   Since the injection nozzle 21 of the nozzle head 20 injects high-pressure water at a pressure of 30 MPa at 170 L / min, not only the inner wall surface of the tank, but also the relatively far wall surface if there is no interference. Can also be washed at high pressure. For this reason, it becomes possible to wash a wide area | region by selecting the injection area | region with little interference.

一般的な反応缶や発酵槽で用いられるタンク３０の多くはバッフル板３２を配置している。このバッフル板３２は撹拌羽根で発生したタンク内の液の回転流の方向を変更させて撹拌効率を上げるものであるため、多くの場合タンク３０の上下に沿って配されている。このため、ノズルヘッド２０をバッフル板３２の陰になっていた領域に近接させることができれば、その上下方向に亘って高圧洗浄水を噴射できるため、比較的遠くの壁面であっても良好に高圧洗浄することが可能となる。   Many tanks 30 used in general reaction cans and fermenters are provided with baffle plates 32. Since the baffle plate 32 is for increasing the stirring efficiency by changing the direction of the rotational flow of the liquid in the tank generated by the stirring blades, it is often arranged along the upper and lower sides of the tank 30. For this reason, if the nozzle head 20 can be brought close to the area behind the baffle plate 32, the high-pressure washing water can be sprayed in the vertical direction, so that the high pressure can be obtained even on a relatively far wall. It becomes possible to wash.

特に、マンホールの両側方のバッフル板３２の陰になっている領域に高圧水を噴射させる場合には、従来の装置ではこの領域にノズルヘッドを近接させることは困難であるが、本考案ではノズルヘッド２０をこの領域に到達させ、タンク３０の上下に亘って高圧洗浄を行うことができる。   In particular, when high-pressure water is sprayed into the area behind the baffle plates 32 on both sides of the manhole, it is difficult for the conventional apparatus to bring the nozzle head close to this area. The head 20 can reach this region, and high-pressure cleaning can be performed over the upper and lower sides of the tank 30.

また、２本の噴射ノズル２１は回転噴射される。具体的には、吊下されたノズルヘッド２０に対して、その鉛直方向に沿った噴射面をその軌跡に含むように噴射ノズル２１は回動噴射される。これにより、ノズルヘッド２０の昇降運動と共に高圧洗浄水を噴射することにより、昇降方向に沿って良好にタンク内壁面を洗浄することができ、タンク上部の壁面にも高圧洗浄水が到達するため、良好に洗浄することが可能となる。   Further, the two injection nozzles 21 are rotated and injected. Specifically, the ejection nozzle 21 is rotationally ejected with respect to the suspended nozzle head 20 so that the trajectory includes the ejection surface along the vertical direction. Thereby, by injecting high-pressure washing water together with the up-and-down movement of the nozzle head 20, the inner wall surface of the tank can be washed well along the up-and-down direction, and the high-pressure washing water reaches the wall surface at the top of the tank, It becomes possible to clean well.

更に、吊下されたノズルヘッド２０は、水平方向に回転させるように構成されている。即ち、吊下されるホース部材１９に対して、水平方向に回転可能な間接具を介してノズルヘッド２０が連結されている。回転する２本の噴射ノズル２１はノズルヘッド２０の側部に取付けられているため、噴射ノズル２１の噴射流によって、ノズルヘッド２０が水平方向に回転する。これにより、複雑な形状を有するタンク内部の全ての領域を洗浄することが可能となることは当然であるが、同じタンク内壁面の被洗浄領域に対して、様々な角度から高圧水を噴射させることができ、洗浄ムラが解消される。   Furthermore, the suspended nozzle head 20 is configured to rotate in the horizontal direction. That is, the nozzle head 20 is connected to the hose member 19 suspended through an indirect tool that can rotate in the horizontal direction. Since the two rotating jet nozzles 21 are attached to the side of the nozzle head 20, the nozzle head 20 rotates in the horizontal direction by the jet flow of the jet nozzle 21. As a result, it is natural that all areas inside the tank having a complicated shape can be cleaned, but high pressure water is sprayed from various angles to the area to be cleaned on the same inner wall surface of the tank. This can eliminate uneven cleaning.

本実施例のタンク内洗浄装置１０に具体的な洗浄操作は以下の通りである。タンク内洗浄装置１０は、図１に示す通り、天井クレーン３５を用いて反応タンク３０上部のマンホール３１にタンク内洗浄装置１０のランス１２先端を挿入し、基台１１をマンホール３１に固定設置する。   The specific cleaning operation of the in-tank cleaning apparatus 10 of the present embodiment is as follows. As shown in FIG. 1, the tank cleaning apparatus 10 uses the overhead crane 35 to insert the tip of the lance 12 of the tank cleaning apparatus 10 into the manhole 31 above the reaction tank 30, and the base 11 is fixedly installed in the manhole 31. .

設置完了後、基台１１の中心を支点として、俯仰ユニット１４と旋回ユニット１５とランススライドユニット１６とランス回転ユニット１７とを駆動し、洗浄されるタンク内壁面に近接させる。具体的には、タンク３０内の各バッフル板３２間位置にランス１２の先端部を近接させ、ホース送りユニット１８によってホース部材１９を出入させつつ高圧水を供給し、ノズルヘッド２０を昇降させつつ高圧水洗浄を行う。   After the installation is completed, the raising / lowering unit 14, the turning unit 15, the lance slide unit 16, and the lance rotating unit 17 are driven using the center of the base 11 as a fulcrum, and are brought close to the tank inner wall surface to be cleaned. Specifically, the tip of the lance 12 is brought close to the position between the baffle plates 32 in the tank 30, high pressure water is supplied while the hose feed unit 18 moves the hose member 19 in and out, and the nozzle head 20 is moved up and down. Perform high-pressure water washing.

これにより、噴射ヘッド２１が上下回転・水平回転しながら高圧水を噴射することにより、バッフル板前面、側面、裏面に残着した樹脂スケールが洗浄・除去される。同様の操作を回転羽根の周囲で行い、回転羽根に残着した樹脂スケールが洗浄・除去される。   Thereby, the resin scale adhering to the front surface, the side surface, and the back surface of the baffle plate is cleaned and removed by ejecting high-pressure water while the ejection head 21 rotates vertically and horizontally. The same operation is performed around the rotating blades, and the resin scale remaining on the rotating blades is washed and removed.

タンク上部の内壁はホース部材１９を送り出さない状態で、ノズルヘッド２０の先端部に取付けた状態で上下回転・水平回転しながら高圧水を噴射することにより、タンク上部壁面に残着した樹脂スケールが洗浄・除去される。   By spraying high-pressure water while rotating up and down and horizontally with the hose member 19 attached to the inner wall of the upper part of the tank and being attached to the tip of the nozzle head 20, the resin scale remaining on the upper wall of the tank is removed. Washed and removed.

以上の通り、ランス１２に曲折部１３を設けたことによって、複雑形状を有するタンク３０内部において、多様な吊り下げ軸を設定することができるとともに、竿状部材駆動手段を用いて竿状部材の先端部を自在に移動することができるため、ランス１２とタンク３０の内部形状とが干渉せず、死角であっても洗浄することができる。   As described above, by providing the bent portion 13 in the lance 12, various hanging shafts can be set inside the tank 30 having a complicated shape, and the hook-shaped member driving means can be used for the hook-shaped member. Since the tip portion can be moved freely, the lance 12 and the internal shape of the tank 30 do not interfere with each other, and even a blind spot can be cleaned.

これにより、タンク外部から洗浄を行うことができるため、タンク内作業における酸欠、高圧洗浄の危険を低減することができる。   Thereby, since it can wash | clean from the tank exterior, the danger of an oxygen deficiency and high-pressure washing | cleaning in the operation | work in a tank can be reduced.

以上説明したとおり、本考案のタンク内洗浄装置によれば、複雑な内部構造を備えたタンクであっても、その内部構造と干渉することなく、隈なくタンク内壁面を高圧水噴射洗浄できる。   As described above, according to the in-tank cleaning apparatus of the present invention, even if a tank has a complicated internal structure, the inner wall surface of the tank can be jet-washed with high pressure water without interfering with the internal structure.
