SUCTION NOZZLE AND METHOD

摘要

A suction nozzle for drawing a viscous material from a container, the suction nozzle comprising a housing defining substantially opposed suction inlet and suction outlet and a suction passageway extending therebetween; and a conduit extending through the housing, the conduit defining conduit first and second end portions and a conduit intermediate portion extending therebetween, the conduit intermediate portion being provided at least in part in the suction passageway and the conduit first and second end portions each extending outwardly from the housing, the conduit first end, second end and intermediate portions together defining an uninterrupted conduit passageway separated from the suction passageway.

1. A suction nozzle for drawing a viscous material from a container, the suction nozzle comprising:
a housing, the housing defining
substantially opposed suction inlet and suction outlet; anda suction passageway extending in the housing between the suction inlet and outlet; and a conduit extending through the housing, the conduit defining conduit first and second end portions and a conduit intermediate portion extending therebetween, the conduit intermediate portion being provided at least in part in the suction passageway and the conduit first and second end portions each extending outwardly from the housing, the conduit first end, second end and intermediate portions together defining an uninterrupted conduit passageway separated from the suction passageway; wherein, when the viscous material has a viscosity that is lowered when the viscous material is heated, circulating a hot fluid through the conduit passageway when the suction nozzle is positioned in the container with the suction inlet submerged in the viscous material lowers the viscosity so as to facilitate drawing the viscous material from the container by exerting a suction at the suction outlet.
