Japanese Patent JP5813693

B2

There is provided a melt circulating drive device that is compact and obtains a large drive force. A melt circulating drive device is mounted on a side wall of a main bath and is driven to agitate nonferrous metal melt present in a melt storage room storing nonferrous metal melt of the main bath. The melt circulating drive device includes a melt drive tank, a melt drive unit, and a partition plate. The melt drive tank includes a hermetically-sealed drive chamber, the drive chamber includes an opening allowing the drive chamber to communicate with the melt storage room, and the melt drive tank stores melt, which flows from the opening, in the drive chamber. The melt drive unit is installed above the melt drive tank. The melt drive unit includes a permanent magnet unit that is rotated about a first up and down axis while making magnetic lines of force up and down pass through the melt present in the drive chamber of the melt drive tank, and a drive unit for the permanent magnet unit that rotates the melt, which is present in the drive chamber, about the first up and down axis by rotationally driving the permanent magnet unit. The partition plate is disposed upright in the drive chamber of the melt drive tank along a direction where the drive chamber and the melt storage room communicate with each other. An outer end of the partition plate is positioned in a region of the opening. An inner end thereof is positioned in the drive chamber. A melt rotating gap is formed between the inner end and an inner surface of the drive chamber facing the inner end. The partition plate divides the opening of the drive chamber into a first opening and a second opening positioned on both right and left sides of the partition plate. The partition plate is rotated by the melt drive unit, and discharges melt, which collides with one surface of the partition plate, from the first opening so as to allow external melt to be sucked into the drive chamber, in which the pressure of the melt has been reduced, from the second opening.
