Title:
FLEXIBLE FOR PNEUMATIC TRANSFER OF BULK MATERIAL
Document Type and Number:
WIPO Patent Application WO2004103868
Kind Code:
A3
Abstract:
The present invention provides a loading arm (10) and apparatus for pneumatically conveying particulate matter. The loading arm is comprised of a flexible hose (30) with a substantially rigid outer casing (16) surrounding said flexible hose (30) and a plurality of hinge mechanisms (20). The outer casing (16) includes a plurality of elongate casing segments (18, 22, 24, 26) disposed end to end and one of the hinge mechanisms (20) interconnects adjacent casing segments (18, 22, 24, 26) allowing the adjacent segments (18, 22, 24, 26) to pivot relative to one another around an axis of rotation normal to a surface of the outer casing (16). The hinge mechanisms (20) also limit rotation about the axis of rotation to within a predetermined range and the axis of rotation are parallel to one another. The loading arm (10) can also include one or two swivel assemblies (28) attached to the charging and discharging ends of the flexible hose (30) and also to the outer casing (16). These swivel assemblies allow the charging and discharging ends (22) to rotate around an axis which is substantially perpendicular to the ground.
