Abstract

PURPOSE:To enhance heat transfer efficiency and to eliminate necessity such that a person enters a stirring tank when supports are fixed by forming the fixing supports of a draft tube as a telescopic system using no bolt or a nut and mounting the same to the upper and lower mirrors of the stirring tank. CONSTITUTION:Cylindrical supports 6, 9 are mounted on the upper and lower mirrors of a stirring tank 1 formed into a split structure by welding or bolts and rod-shaped supports 7, 8 are mounted on a draft tube 4. The draft tube 4 is fixed by inserting the rod-shaped supports 7, 8 of the draft tube 4 in the holes of the cylindrical supports 6, 9. That is, since the supports are provided to the upper and lower mirrors of the stirring tank 1, it is unnecessary to cut the heat transfer coil 3 arranged to the outside of the draft tube 4 and heat transfer efficiency is enhanced and, since the supports are used in a telescopic system, it is unnecessary that a person enters the tank when the supports are fixed.

[Means for Solving the Problems] In order to achieve the above object, draft tube fixing supports are provided in the vertical direction of the stirring tank, that is, in the direction of the upper and lower mirrors of the tank, so that the draft tube is fixed between the tank walls. The draft tube can be fixed without the need to separate the heat transfer coil installed in the heat transfer coil, and the draft tube can be fixed without using bolts or nuts as a plug-in fixing method.

[0007] This insertion type support for the draft tube consists of dividing the stirring tank by the main body flange, first attaching cylindrical supports to the upper and lower mirrors of the tank, and also attaching cylindrical supports to the upper and lower surfaces of the draft tube. A rod-shaped support is attached taking into consideration the fit tolerance with the cylindrical support.

[Operation] Insert the rod-shaped support attached to the lower surface of the draft tube into the cylindrical support attached to the lower mirror divided by the main body flange to fix the lower surface side of the draft tube. Further, the upper surface side of the draft tube is fixed by inserting the cylindrical support attached to the upper mirror divided by the main body flange into the rod-shaped support attached to the upper surface of the draft tube. By tightening the main body flange with bolts, the draft tube is fixed to the inner surface of the tank at its upper and lower surfaces. The heat transfer coil can be formed integrally, and the fluid flow within the tank is uniform.
