SHAFTLESS SCREW CONVEYOR FOR TRANSFERING SLUDGE

摘要

The present invention relates to a screw conveyor for transferring a sludge passing a dehydration device, which prevents that a stress is concentrated on a connection part to improve durability, even if a shaftless screw (120) is rotated to be separated from a vertical axis line of a driving shaft (110) by a load by adding a universal joint (130) between a shaftless screw (120) end and the driving shaft (110) in order to solve a problem that the stress is concentrated on the connection part of a screw end and the driving shaft and damaged when a screw is rotated in a state disjoined from the vertical axis line of the driving shaft by the load of the sludge loaded on the shaftless screw.;COPYRIGHT KIPO 2019
