The present invention concerns an on-the-fly long-running rotary filtration screen comprising a rotating split-flow bar, a filtration sleeve, filtration screen, a large gear, a small gear, a motor, a stop disc, two square keys, a outlet housing and a residue-removing rod. The main feather of the present invention is to employ the filtration bar to rotate continuously, mix and transport the plastic raw material toward the space formed between the split-flow and the filtration sleeve, thereby allowing the plastic raw material to flow into the conical hole and to be discharged from the funnel-shaped outlet of the outlet housing. When the motor is actuated, the hydraulic cylinder is also actuated with the motor. The action of the hydraulic cylinder causes the round rod to move forward, which in turn causes the filtration bar to move forward to a certain distance and backward to its original position, thereby generating a reciprocating action. Meanwhile, the plastic raw material is being mixed and stirred continuously, the action of transportation causes extraneous matters to be pushed into the space of the residue-removing thread and the guide bar is inserted into the guide bar slot, which is equipped in the residue-removing bar, to cause the residue-removing bar to rotate continuously, the action causes the extraneous matters to be pushed outward, thereby allowing the extraneous matters accumulated inside the space of the residue-removing thread to be discharged from the main housing, thus allowing the filtration device to operate continuously without stopping.
