Centrífuga of double empujador as well as device of base of empujador

摘要

Pusher bottom device for a double pusher centrifuge (1) for the separation of a mixture (17) in a cake of solid substance (14, 15) and a liquid (39), in which in an outer annular zone ( 51) of the bottom device of the pusher (5) are provided a plurality of axial through holes (12), which in the assembled state connect a front area (151) and a rear area (141) of a screen drum (6). ) of the double-pusher centrifuge (1), and the bottom device of the pusher comprises an input disk (29), so that the mixture (17) can be introduced in the operating state through the input disk ( 29) in an empty space (16), which is formed during the displacement of the cake of solid substance (14, 15) on the screen drum (6), characterized in that between an input edge (291) of the input disk (29) and a bottom plate of the pusher (52) of the bottom device of the pusher (5) with inlet zone (50) 0) an uninterrupted inlet gap (53) is configured in the circumferential direction (U), through which the mixture (17) can be applied in the operating state and in the assembly state in the vacuum space (16) on the screen drum (6).
