CLOSED TYPE AIR STIRRING DEVICE USING DC MOTOR

摘要

PURPOSE: A closed type air stirring device using a DC motor is provided to efficiently stir an electrolyte while preventing the electrolyte from being discharged to an exterior by injecting ambient air into the closed type air stirring device. CONSTITUTION: A closed type air stirring device includes an air injection pipe, an outer supporter(3) for supporting the air injection pipe, and a DC motor(6) for injecting ambient air(5) into the air injection pipe. The DC motor(6) has an eccentric rotating shaft(7). As the DC motor(6) rotates, a long axis and a short axis, which are created due to the eccentric rotation of the eccentric rotating shaft(7), alternately pass above the upper portion of the air injection pipe. Then, air contained in the outer supporter(3) is injected into the air injection pipe.
