を経て下向ノズル５及び水平ノズル６より噴出せしめら
れる。That is, the liquid drawn out from the lower part of the storage tank 1 is sent to the circulation pump 7, the circulation pipe 8, the rotation support joint 2, the rotation axis pipe 3, and the horizontal pipe 4.
After that, it is ejected from the downward nozzle 5 and the horizontal nozzle 6.
下向ノズル５からの噴流は、貯槽底部１Ｂに堆積してい

４のたわみは該水平管４と回転軸管３との間に吊り棒１
０を架設することにより防止している。In such a stirring device, vertical loads such as the rotating shaft tube 3 and the horizontal tube 4 are supported by the rotation support joint 2, and the deflection of the horizontal tube 4 is suspended between the horizontal tube 4 and the rotating shaft tube 3. stick 1
This is prevented by constructing 0.

転式ジェット攪拌装置を取付る場合は、回転支持継手を
、貯槽底板に設置する必要がある。In contrast to the type of agitation device that is attached to the rotary support joint 2 or the top plate 1A of the storage tank 1 as described above, a rotary jet agitation device is used for floating roof type storage tanks and open storage tanks without roofs, which are used for petroleum storage tanks, etc. When installing the device, a rotation support joint must be installed on the bottom plate of the storage tank.
このようにすると貯槽の構造に与える影響が少ないなど
の経済的長所がある。This method has economical advantages such as less influence on the structure of the storage tank.
しかしながら翼部材〔第１図で示したものでは水平管４
に相当する。However, the wing member [in the one shown in Fig. 1, the horizontal pipe 4
corresponds to
〕の垂直荷重を回転支持継手のみで支えるような構成を
採ることは、貯槽径が大きくなると翼部材も長尺となり
回転支持継手に応力が集中するため事実上、困難であり
、また仮に技術的に可能であっても、経済的に好ましい
ものではない。] In practice, it would be difficult to adopt a configuration in which the vertical load of the rotary support joint is supported only by the rotary support joint. Even if it is possible, it is not economically preferable.
本発明は以上の点に鑑みてなされたものであり、以下そ
の実施例を第２図に基づき説明する。The present invention has been made in view of the above points, and an embodiment thereof will be described below based on FIG. 2.
第２図において１１は浮屋根１１Ａを有する貯槽であり
、その底部中央に回転支持継手１２を設けている。In FIG. 2, 11 is a storage tank having a floating roof 11A, and a rotation support joint 12 is provided at the center of the bottom thereof.
この回転支持継手１２からは相反する二方向あるいは放
射方向に翼部材となる長尺の水平管１３が伸びている。A long horizontal pipe 13 serving as a wing member extends from this rotary support joint 12 in two opposite directions or in radial directions.
水平管１３は複数の下向きノズル１４及び水平ノズル１
５を有していることは前述の通りである。The horizontal pipe 13 has a plurality of downward nozzles 14 and a horizontal nozzle 1
As mentioned above, it has a value of 5.
水平管１３は貯槽底板１６の近傍に設けられ、かつその
上部に密閉管１７が平行に取り付けられている。The horizontal pipe 13 is provided near the storage tank bottom plate 16, and a sealed pipe 17 is attached above it in parallel.
密閉管１７は本発明における浮力体の一例である。The sealed tube 17 is an example of a buoyant body in the present invention.
浮力体としては密閉管１７の他に、対象とする液よりも
密度（比重）の小さいものであれば例でもよい。In addition to the closed tube 17, the buoyant body may be any other body as long as it has a lower density (specific gravity) than the target liquid.
１８は循環ポンプであって、攪拌効果を向上させるため
に貯槽底部の液を循環パイプ１９を通して回転支持継手
１２、水平管１３に送る。A circulation pump 18 sends the liquid at the bottom of the storage tank through a circulation pipe 19 to a rotary support joint 12 and a horizontal pipe 13 in order to improve the stirring effect.
以上の構成によると水平管１３には常時密閉管１７の容
積に相当する液質量分の浮力が働くので、水平管１３が
たわみ、該管１３先端が固形物堆積層に埋没したり貯槽
底板１６に接したりするのを防止でき、このことは水平
管１３の回転抵抗を小さくするのに効果がある。According to the above configuration, a buoyant force equal to the liquid mass equivalent to the volume of the sealed tube 17 acts on the horizontal tube 13 at all times, so that the horizontal tube 13 is bent, and the tip of the tube 13 is buried in the solid matter accumulation layer or the bottom plate 16 of the storage tank 13 is bent. This is effective in reducing the rotational resistance of the horizontal tube 13.
また水平管１３と回転支持継手１２との接続部などに応
力が集中するのを防止できる。Further, it is possible to prevent stress from concentrating on the connection portion between the horizontal pipe 13 and the rotation support joint 12, etc.
以上のように本発明によると翼部材となる水平管が長尺
なものから構成されている場合であっても、極めて簡単
な構成によって回転支持継手に応力が集中したり、水平
管がたわんだりするのを効果的に防止することができる
。As described above, according to the present invention, even when the horizontal pipe serving as the wing member is made of a long piece, the extremely simple structure prevents stress from concentrating on the rotation support joint and bending of the horizontal pipe. This can be effectively prevented.
