The utility model discloses an extraction tube based on a sludge dryer, and relates to the technical field of extraction tubes in sludge dryers, and the extraction tube is characterized by comprising a rotating frame and a workbench, a sliding rail is arranged on the workbench, limiting grooves are symmetrically arranged on the workbench at the position of the sliding rail, a protection box is connected in the sliding rail in a sliding mode, and the protection box is connected with the rotating frame in a sliding mode. The upper end of the protection box is connected with a handle, the protection box is provided with a pick-and-place mechanism, and the pick-and-place mechanism is used for installing the protection box on a workbench, so that the problems that in the background technology, the extraction pipe has the core function of automatically discharging condensate water, percolate or cleaning water, liquid cannot be normally discharged after blockage, and the operation is inconvenient are solved. The problems that liquid is accumulated in the equipment (such as a drying chamber, a condensing system or a collecting tank) due to the fact that the sludge enters the drying chamber, the effective drying area is reduced and the drying efficiency is reduced when accumulated liquid occupies the drying space, and the water content is increased and the product quality is influenced due to the fact that water retention possibly reversely permeates into the dried sludge are solved.
