To provide a magnet pipe conveyor capable of transporting sludge in pushing up mechanically in the condition that the sludge is attracted magnetically and making service irrespective of the place of service from a handy type to a large-sized while the constitution remains very simple.

The magnet pipe conveyor is configured so that a magnet rod which is magnetized spirally or whereto a magnet piece is adhered is covered with a non-magnetic outer cylinder such as a stainless steel pipe with a minimum gap to allow rotation and a transporting coil is installed having a minimum gap capable of rotating using the outer cylinder as a guide, wherein the spiral pitch of rod magnetization is made identical to the winding pitch of the transporting coil, and also phase alignment is made so that the place of magnetization lies over approximately 3-5 mm over the transporting coil, and the sludge is pushed up mechanically and transported in such a condition as attracted magnetically by allowing the magnet rod and coil to make synchronized rotation.
