ABSTRACT:
The invention is directed to an apparatus for withdrawing a sample from a ass melting furnace. The apparatus includes a gripper for taking the sample and can be introduced through an opening in the furnace into the interior thereof. The apparatus includes a rectangular vertically upright open guide frame provided with vertical inner guides mounted on the sides of the frame. A carrier frame is mounted on the inner guides and is displaceable relative to the guide frame. The base of the guide frame is penetrated by a guide tube. A pull rod is coaxially and displaceably mounted in the guide tube and is fixedly attached to the base of the carrier frame. Two pairs of articulated lever units for pivoting two cooperating gripper half shells are mounted at the end of the guide tube and at the end of the pull rod. When pivoted together, the gripper half shells conjointly form a closed space to accommodate the sample. The apparatus can be operated from a remote location in a cell of a nuclear facility to obtain representative samples from various regions of the molten glass.
