Title:
ROTARY CYLINDER-TYPE SCREW-CONVEYOR, BULK MATERIAL SUCTION SYSTEM, SHIP-UNLOADING EQUIPMENT AND ROTARY CYLINDER-TYPE SCREW MECHANISM
Document Type and Number:
WIPO Patent Application WO/2012/116648
Kind Code:
A3
Abstract:
The present invention relates to a rotary cylinder-type screw-conveyor, which comprises a screw (5) that is divided into a first and a second screw section comprising a shaft (6) and a helical blade (7) fixedly arranged thereupon; a first cylinder housing (4) arranged around the first screw section; a second cylinder housing (10) arranged around the outside of the first cylinder housing (4) at the end of the first cylinder housing (4) adjacent to the entry side of the rotary cylinder-type screw-conveyor; the end edge of the helical blade (7) on the first screw section is fixedly engaged with the inner wall of the first cylinder housing so as to form a spiral conveying space bounded by the inner wall, the outside surface of the shaft (6) and the helical blade (7); the inner wall of the second cylinder housing is separated from the end of the helical blade (7) on the second screw section; when the first cylinder housing is driven to rotate by a driving device, said housing drives the screw to rotate synchronously at the same time. Also disclosed are a bulk material suction system including the present rotary cylinder-type screw-conveyor and ship-unloading equipment including the bulk material suction system. The present cylinder-type screw-conveyor allows the drive device to not enter into contact with the bulk material, thus improving the working environment and improving the efficiency of ship-unloading equipment.
