RUEHRGERAET, INSBESONDERE FUER GUELLE, MIT EINEM AXIAL VERSTELLBAREN, DREHBAREN RUEHRFLUEGELROHR

摘要

The stirring appliance has an axially adjustable, rotatable stirrer paddle tube (1) with a square cross-section. A rope winch (2) is used as the adjusting device. The rope winch (2) with the pulley (3) co-rotates with the stirrer paddle tube (1). When the stirrer paddle tube (1) is adjusted axially, the drive via the drive motor (6) is stopped, and a hand crank is used to move the rope winch (2) in the one or the other direction to achieve the axial height adjustment of the stirrer paddle tube (1). The rope winch (2) is self-arresting. This construction ensures that floating or suspended solids do not attach themselves to the rope (9) of the rope winch (2). <IMAGE>
