LOW-ENERGY EXTRUDER-PUMP SYSTEM |
摘要 |
The invention is directed to a low-energy extruder-pump system. …<??>The thermoplastic material is fed into a screw extruder wherein the screw (12) comprises a feeding section (16) of relatively deep root depth (HF), a transition section (18) of intermediate and decreasing root depth, a metering chamber (20) of relatively shallow root depth (HM), and a mixing section (22) having flute passages (26) formed by longitudinally extending and alternate grooves and lands; the resulting extrudate is then passed, through breaker plate (34) and adapter means (36), to a rotary gear pump (40) and discharged to a die (54). …<??>This extruder-pump system provides a required pumping action at a lower level of energy consumption than was attainable in conventional systems. |
