Abstract
A system for conveying pasty material through a conduit has an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit. A drive rotates the rotor and thereby draws the pasty material in through the intake port and expels the drawn-in material as a compressed-material strand into the conduit. A valve supplies gas pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.
Claims16
A system for conveying pasty material through a conduit, the system comprising:
- an eccentric screw pump having a stator, a rotor that rotates in the stator, a housing with an intake port, and an output port connected to the conduit;
- drive means for rotating the rotor and thereby drawing the pasty material in through the intake port and expelling the drawn-in material as a compressed-material strand into the conduit;
- and
- means including a valve for supplying compressed-air pulses to the conduit at time intervals for separating the compressed-material strand into material plugs of limited length traveling through the conduit.
A method of conveying pasty material through a conduit, the method comprising the steps of:
- pumping the material with an eccentric screw pump into an upstream end of the conduit to form therein a compressed-material strand moving downstream;
- and
- injecting a pulse of compressed air into the conduit to subdivide the strand into a succession of material plugs of limited length traveling downstream in the conduit.
