STIRRER BLADE FOR WATER TREATMENT SYSTEM

摘要

PURPOSE: A stirrer blade used in a water treatment system is provided to improve mixing and coagulation efficiency of fluid by rapidly mixing fluid with chemicals in a mixing basin and by forming a large flock in a coagulation basin. CONSTITUTION: A plurality of stirrer blades(2) is radially attached to a stirrer shaft(1). Pitch of the stirrer blades(2) is gradually reduced from the root portion(24) to the top portion(23). The stirrer blades(2) are bent at a predetermined angle along an outer portion of a tail(22) from a nose(21) thereof. The stirrer blade(2) includes a first plane(25) attached to the stirrer shaft(1), a second plane(26) bent along an outer portion of the tail(22) in a diagonal direction with respect to the first plane, a third plane(27) bent along an outer portion of the tail(22) in a diagonal direction with respect to the second plane(26), and a fourth plane(28) bent along an outer portion of the tail(22) in a diagonal direction with respect to the third plane(27).
