Definitions
- At least one of the at least one shafts is a driving shaft.
- a driving shaft shall be construed as a shaft that is actuated .
- the apparatus is adapted to admix fluid additives into a medium to be pumped
- Sample additives used as blowing agents for plastics can be butane, pentane, carbon dioxide or nitrogen in fluid stage.
- the apparatus comprises, in addition to the first gear pump, a second gear pump.
- Each gear pump of this embodiment is functionally connected with one of the screw conveyors.
- each gear pump is functionally connected by means of a drive shaft for driving the respective screw conveyor with said screw conveyor.
- the extruder speed will be controlled in that way, that the exit
- the inlet pressure of the first gear pump can best be controlled by varying the extruder speed.
- FIG. 5 is a schematic representation of the extrusion process.
- An extruder 21 pumps the medium to be pumped with help of a driving torque MX into a mixing block 24.
- the medium to be pumped enters Al the gear 2, 2' and is pumped A2 by displacement into a conveyor screw 6, where it is injected with an additive.
- a deflection baffle deflects A3 the medium into a second conveyor screw 7, directing the medium back to the gear pump housing and therefrom a into a feeding block and extrusion die nozzle 23.
- the shaft 3 actuating the gear pump 2 by rotating the gear cock 2 ' has a driving torque Ml transferred by means of the cock 2' to the cock 2 resulting in a driving torque Ml' .
- the driving torques Ml and Ml' of the gear pump are coupled with the driving torque of the conveyor screws M2 , M2' .
