5.4 Fuel extraction with funnel discharge
Funnel discharge AP
For part no., see pricelist
■ Funnel discharge up to 6.0 m diameter
■ Funnel discharge up to 7.5 m diameter
Fuel discharge by means of an agitator installed underneath a funnel
In its centre, the discharge screw conveyor is driven via a solid uni-
versal joint. When the fuel store is full, the screw conveyor inclines
towards a vertical position. The funnel limits the angle of the screw
conveyor when the fuel store is empty. The agitator is driven via a
spur geared screw conveyor motor. In the case of fuel compression
in the discharge casing as a result of increased drive power con-
sumption, the supply direction of the screw conveyor is changed for
a period set at the factory. This releases the compression, prevent-
ing a fault.
Standard delivery:
■ Funnel discharge with drive unit 3 x 400 V
■ Automatic switching of the drive for the spur geared screw con-
veyor motor for both rotational directions
■ Safety limit switch installed on inspection cover of discharge cas-
ing
