Basin for water purification plant, has multi plate cover clamped to top edge of basin by fitting allowing cover to move relative to the wall

摘要

The cover (3) is clamped to the top edge (2) of the basin wall (1) by a fitting that allows the cover to move relative to this top edge. A liquid vessel, especially a basin for a water purification plant, has a preferably ring-shaped wall with its top edge supporting a cover over which the wheels of a movable bridge above the vessel can move. The cover comprises a number of plates (4) and the fitting clamping the cover to the top edge of the wall allows the cover to move relative to this top edge. An Independent claim is also included for the cover plate
