The invention discloses a method for taking semi-dried sludge out of a storage bin and conveying the semi-dried sludge. According to the method, the sludge temporarily stored in a semi-dried sludge stock bin can be conveniently taken out and conveyed. The method comprises the steps that S1, the sludge on the surface of a sludge material layer is pushed layer by layer to enter a buffer groove through a rotating scraper set of a movable rotary scraper device; S2, the semi-dried sludge entering the buffer groove slidably enters a spiral conveyer under the effect of gravity force, and the sludge is conveyed to a scraper type bucket-elevating conveyor through the spiral conveyer; and S3, after being elevated by the bucket elevator, the sludge is conveyed to a feeding buffer bin in front of a furnace through a chain scraper conveyor or a belt conveyor and the like, and then the sludge is put into the furnace to be subjected to incineration.
