Suction device for removing packing coke from baking chambers for carbon bodies.

摘要

The invention relates to a suction device for removing packing coke from baking chambers for carbon bodies, in which the baking chambers are served by a mobile crane running on a track, which crane is equipped with suction pipe and silo and in which the vacuum for the suction pipe is produced by a stationary plant and conveyed to the suction device from a closed duct (1) which runs parallel with one of the rails of the crane track, to a sliding box (2) mounted on the crane. The duct (1) has a slide surface in which there are disposed valves (12) which are opened by pneumatic cyclinders (9) when an activating rail (6), mounted on the sliding box (2) passes the valves (12) in the vacuum duct (1), and in that the sliding box (2) rolls on wheels (3) and is fitted with guide wheels (4), and further in that the box (2) is fitted with a sliding gasket (8), consisting of a rubber skirt inserted into which there is an elastic body which slides along the vacuum duct (1) of a material with a low co-efficient of friction.
