Abstract
A suction tube unit for removing packing coke from vertical spaces within a ring furnace for producing carbon bodies includes a plurality of elongated suction and air supply tubes, the tubes being arranged to extend parallel to each other and being aligned in a single straight row, with each adjacent pair of the suction tubes being separated by a separate one of the air-supply tubes, thus forming an elongated assembly adapted to fit within the vertical space of the furnace. The assembly is supported at an upper portion thereof by a telescopic mounting. All of the tubes are open at lower ends thereof. A suction device is connected to the upper end of the suction tubes for creating a vacuum within the suction tubes to thereby withdraw the packing coke therethrough. Upper portions of the air-supply tubes have therein orifices to supply ambient air into the air-supply tubes and to aid in withdrawal of the packing coke through the suction tubes.
