Abstract: Aspects of the disclosure provide a screw conveyor for discharging solids from a solid/liquid waste stream is provided and comprises a cylindrically shaped screen segment including perforated screen segments and an inlet for receiving a stream including solid and liquid materials, the perforated portions configured to permit liquids and smaller materials to pass therethrough. The conveyor includes a rotor auger disposed within the screen segment and includes helical flights configured to move solid materials larger than perforations on the perforated screen to move vertically when rotated. A drive motor is included to rotate the rotor auger and anti-rotation elements are disposed radially outward between adjacent perforated screen segments and configured to prevent rotation of solid materials to permit the rotor auger to move the solid materials in an axial direction of the rotor auger rotation.

Abstract: A conveying screw for a food waste disposal device that can stir, crush and cut food waste generated from homes or restaurants, while transferring the food waste, to reduce the amount of the food waste, includes a rotational shaft, and a plurality of spiral rotor blades installed to an outer peripheral surface of the rotational shaft in a spiral pattern to stir, crush and cut food waste. Each of the rotor blades is provided with a plurality of air supply holes penetrating the rotor blade to supply external air to the food waste between the opposite rotor blades, thereby generating bubbles from the food waste and then discharging vapor.

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.

Abstract: The present invention relates to a screw transport apparatus for bottles, comprising: —a support structure, which extends longitudinally between a bottle inlet 1a and a bottle outlet 1b of the apparatus, and —a spiral-shaped helical body, which is associated with the support structure and extends axially parallel to the support structure between two own axial ends. The above spiral-shaped helical body can be rotated on itself about its own longitudinal axis to move bottles in cooperation with the support structure. The spiral-shaped helical body comprises at least two spiral-shaped seats, which extend coaxially between the two axial ends. They are angularly offset from each other and differ from each other by the shape and/or dimensions of the relative bottle housing compartment defined by each of them. The two spiral-shaped seats are intended to be used alternatively to the other for the transport of bottles having different shapes and/or dimensions.

Abstract: A cantilevered screw assembly comprising a speed reducer to facilitate rotation of a screw. The speed reducer may be connected to a torque arm that is adapted to control or limit undesired movement (e.g., wobbling, orbital movement, etc.) of the screw during operation. In effect, one exemplary embodiment of a speed reducer may essentially float on a pivoting torque arm (and the shaft of the screw) such that the torque arm is adapted to limit undesired movement of the speed reducer and screw. As a result, an exemplary embodiment may eliminate the need for alternative drive systems or other means to control undesired movement of the screw. An exemplary embodiment may be particularly useful for light or infrequent duty or other small-scale applications to reduce the likelihood of a breakage of a screw or another portion of a cantilevered screw assembly (e.g., the bearing(s) or bearing assembly, the gears, etc.).

Abstract: Auger conveyors most commonly employed in industries where the horizontal and/or vertical transfer of solids or semi-solid materials is required. Auger conveyors employ a rotating helical screw blade, commonly known as fighting, which rotates about on an inline axis within an inline conduit. Described herein is an auger conveyor which does not need to follow the traditional rule of rotating about on an inline axis. A flexible wire rope shaft is employed to rotate about on an infinite number of axes thereby facilitating an auger conveyor connected to the flexible wire rope shaft through buttons, to traverse a non-linear path.
