Title: A SCREW DEVICE FOR A POWER GENERATION OR A MATERIAL HANDLING APPARATUS
Abstract:
A screw device for a power generation or a material handling apparatus is disclosed. In particular a support structure or central cylinder is provided. To the central cylinder screw members are connected. The screw members are formed from pipe portions that are joined together and wound around the central cylinder to form a number of helical pipes. Attached to the upper end of each helical pipe are feeder members that together form an annular aperture feeding the helical pipes. The number of feeder members and pipes is selected depending upon the design flow of the device.
