、この形状(二のみ限定されるものではない。The stirring blades 3 have a conical shape at the bottom 20 of the cleaning tank (the lower ends of vane-shaped triangular blades facing each other are cut out). This space forms the washing liquid introduction chamber 5.The shape and dimensions of the above-mentioned notch are determined by the specific gravity of the powder to be washed, the floating state C2, and the selection of the rotation speed of the agitator shaft 4. Relatedly, according to experience, the agitating blades can be cut out to have a trapezoidal shape, but are not limited to this shape.
撹拌翼3と洗浄槽底部2の斜面とのクリアランスはでき
るだけ小さくするのが攪拌効率の点で好ましい。In terms of stirring efficiency, it is preferable to make the clearance between the stirring blades 3 and the slope of the cleaning tank bottom 2 as small as possible.
