Patent
CA 2301427
A melt withdrawal device for melt furnaces for charging casting machines has a melt conveying pump (1) comprised of a pump tube (2) forming a lower melt inlet (3) and an upper melt outlet (4) and of a pump shaft (5) extending inside the pump tube (2) and carrying a pump rotor (6). To achieve a melt conveyance which is largely independent of the melt level variations inside the melt furnace and can thus be dosed properly, a charging means (7) for keeping constant the pump head (h) is provided before the melt conveying pump (1), which charging means (7) comprises a charging tank (8) accommodating the pump tube (2) with the melt inlet (3) and a charging pump (10) capable of filling the charging tank (8) with melt up to a melt overflow (9) determining the charging height, where the delivery rate of the charging pump (10) exceeds that of the conveying pump (1).
