STIRRING APPARATUS FOR PRECIPITATION TANK

摘要

PROBLEM TO BE SOLVED: To inhibit forcible force from being applied to an arm and a center axis, prevent a stirring apparatus from being broken, and provide the stirring apparatus to be economically installed in a precipitation tank by swinging and displacing the center axis and shifting the axis from the axial center of the precipitation tank in the case the arm is shifted from a core circle. ;SOLUTION: One end parts of a supporting arm 3 and a pulling arm 4, which are united not linearly but arranged at an angle on an upper end of a center axis 2 installed in the lower end of a supporting part supported in the center part of the inner bottom of a circular precipitation tank 1, are joined and at the same time the other ends of the supporting arm 3 and the pulling arm 4 are respectively engaged with a rail 10 laid on the upper end of the precipitation tank 1 to make both arms movable and rotatable along the rail 10, so that the center axis 2 can be kept uprightly. A rotating and driving apparatus 5 which comprises a motor 52 and can be self-driven along the rail 10 is joined to one of the arms and a stirring body 6 is installed in the arm or the center axis 2.;COPYRIGHT: (C)1998,JPO
