Abstract:
1. An injecting device for use with an underwater pelletizer apparatus that extrudes and cuts polymer strands into pellets, said apparatus including piping to introduce water into said pelletizer and a transport pathway to transport a water and pellet slurry out of said pelletizer and to a centrifugal dryer for drying said pellets, said injecting device comprising: a positionable nozzle assembly having a movable nozzle tube for introducing a pellet speed expediter into said water and pellet slurry to increase a velocity of the pellet slurry to and through the dryer such that more internal heat of the pellets is retained, said nozzle tube being selectively movable to different positions between a fully inserted position in which the nozzle tube is positioned forwardly to be within the piping and a fully retracted position in which the nozzle tube is withdrawn from the piping to provide unobstructed flow of the slurry through the piping and to prevent pellet hang-up on the nozzle tube.
