The utility model discloses a rotating single-screw extruder barrel with threads, and relates to a mechanical component. The barrel comprises a single screw (2) and a rotating barrel (1) with the threads, wherein a thread is formed in the inner side of the barrel; the revolving direction of the thread in the inner side of the barrel is opposite to that of the threads matched with each other and formed in the single screw; the barrel is fixed on an extruder body through a rolling bearing. According to the rotating single-screw extruder barrel with the thread, the screw and the rotating barrel with the thread are combined for voltage buildup; the screw and the barrel rotate in opposite directions, so that the relative velocity of materials is increased, and the shearing capability is improved; the voltage buildup capability, mixing capability, shearing capability and extrusion capability of an extruder can be greatly improved.
