FIELD: transport engineering.
SUBSTANCE: transport device for moving fluid material contains a screw conveyor. The screw conveyor contains a screw element, which is wound on a shaft extending along the longitudinal axis, and an outer casing, in which the screw element is at least partially located. The screw element has a plurality of turns. The outer casing has an inner surface. A chamber is formed between two successive turns and the outer casing. The outer casing is at least partially made of a deformable polymeric material such that when a solid particle of fluid material moved by the screw element gets between the head surface of one turn and the inner surface of the outer casing, said casing is deformed in a reversible manner outward in the radial direction to allow the transition of the outer casing. solid particle from one chamber to another, adjacent chamber, by passing between the head surface of the coil and the inner surface of the outer casing.
EFFECT: reduction in the design power and noise level of the transporting device is achieved.
