ABSTRACT:
An automatic cleaning device is employed in an extracting furnace of an apparatus for analyzing gases in metals, the furnace including upper and lower electrodes relatively movable between a closed position, whereat a crucible containing a sample to be analyzed may be contacted and heated by the electrodes, and an open position, whereat the electrodes are spaced from each other. The automatic cleaning device cleans the upper and lower electrodes and includes a support bracket mounted for movement laterally of the electrodes. A cleaning unit is supported on the support bracket and is movable thereby between a first position located laterally of the electrodes and a second position located between the electrodes. The cleaning unit includes a crucible removal device to remove a spent crucible from the electrodes upon movement of the cleaning unit to the second position thereof. The cleaning unit includes upper and lower brushes rotatable to clean the upper and lower electrodes. The cleaning unit is mounted on the support bracket for vertical movement relative thereto. Thus, when the cleaning unit is in the second position thereof, relative movement between the upper and lower electrodes toward the closed position thereof causes the cleaning unit to be moved vertically until the upper and lower cleaning brushes are contacted with and clean the upper and lower electrodes.
