Device for restricting hot, dust-laden gas flows

摘要

In a device for restricting hot, dust-laden gas flows and, in particular, dust-laden hot cooling air from clinker coolers (4) in a tertiary air duct (5) of a clinker kiln, the restrictor (6) is formed by segments (8) which are displaceable transversely to the direction of flow in a duct (5) and which are connectable with one another.

主权项

1. A device for restricting hot, dust-laden gas flows in an air duct, comprising
a restrictor member and a displacement drive for the restrictor member, wherein said restrictor member is designed as a slide formed of segments, said slide is displaceable in a substantially vertical direction transversely to a direction of flow in the duct, said segments are articulately connected with one another and are connectable with the displacement drive, said displacement drive is detachable from the segments for installation of further segments and is reconnectable with the further segments, said displacement drive cooperates with the slide via a force-locking engagement comprising fixing means for retaining the segments in their respective positions upon detachment of the displacement drive from the segments, said fixing means being arranged on the displacement drive outside of and above the air duct, and wherein the segments are arranged to suspend from the duct.
