The present invention concerns an on-the-fly long-running rotary filtration screen device, wherein a split-flow bar and a filtration sleeve are screwed together to form a filtration bar, a filtration screen is inserted onto the cylinder on the filtration sleeve, the cylinder is equipped with round holes, the split-flow bar is equipped with two square slots facing opposite from each other, a large gear to be installed onto the split-flow bar also possesses identical square slots, so that the split-flow bar and the large gear are attached to each other by means of inserting two square keys into the two square slots and then inserting a stopping disc, the bottom of the main housing is equipped with a circular sunk slot connecting to an outlet housing, a residue-removing rod is inserted into a round hole at the lower part of the main housing and, after actuating a motor, the rotating large gear causes the filtration bar to rotate, the action of a hydraulic cylinder pressing against a round rod at the front part of the split-flow bar causes the filtration bar to reciprocate, thereby allowing a plastic raw material to be filtered and agitated by the filtration screen and the small holes on the filtration cylinder to obtain a homogeneous purified plastic raw material, the extraneous matters are collected by a-residue-removing rod, and a hydraulic cylinder behind the residue-removing bar pushes the residue-removing bar outward, thereby eliminating the extraneous matters and achieving the excellent effects of obtaining a higher-purity raw material on the fly for a long period of time.

An on-the-fly long-running rotary filtration screen device comprising a main housing, said housing includes a round through hole and an intake opening in the upper part of the housing which communicates with the housing through hole via a funnel-shaped opening in said housing, the device further comprising a filtration bar formed of a split-flow bar, a generally cylindrical filtration sleeve having a threaded hole, a cylindrical filtration screen, a large gear and a rotating small gear connected to a motor, a stopping disc, two square keys, an outlet housing and a residue-removing rod, wherein (1) one end of the split-flow bar of the filtration bar is equipped with a round rod connected to a hydraulic cylinder, the other end of the split-flow bar is also equipped with a round rod, the end of this other end round rod is equipped with a protruding threaded rod, and said protruding threaded rod is screwed into the threaded hole of the filtration sleeve, (2) the filtration sleeve is equipped with a number of small round holes that are opened to the round hole center inside the filtration sleeve, and the outer surface of the cylinder is equipped with the filtration screen, (3) the upper and lower sides of the split-flow bar are each equipped with a long square slot, the filtration bar is inserted into the round through hole of the main housing, and the large gear, being annular shaped with a round center hole having two opposed square slots, is then inserted onto the split-flow bar, which is followed by inserting the two square keys into the spaces formed by the two opposing square slots of the split-flow bar and the two opposing square slots of the round hole of the large gear and then inserting the stopping disc, being annular shaped with a round center hole having two opposed square slots, next to the large gear in a manner that the two square keys are housed inside the two square slots of the stopping disc, thereby immobilizing the large gear and the stopping disc, (4) the bottom of the main housing is equipped with a circular sunk slot, the circular sunk slot is equipped with two small threaded holes, said two threaded holes are aligned with the two threaded holes of the outlet housing, and then a pair of screws are inserted, thereby fastening the outlet housing onto the main housing, (5) the residue-removing rod is inserted into a non-piercing round hole at the lower part of the main housing and is coupled to said hydraulic cylinder, (6) after actuating the motor and the hydraulic cylinder, the rotating small gear which is coupled to the large gear causes the large gear to rotate, and, since the large gear and the split-flow bar are bound to each other by means of the two square keys, the filtration bar also rotates inside the round through hole of the main housing, (7) the action of the hydraulic cylinder causes the filtration bar to reciprocate, thereby allowing a plastic raw material to be fed from the intake opening on the upper part of the main housing and through said funnel-shaped opening in said housing, pass through the filtration screen and the small round holes, mix inside the filtration bar, flow into a conical opening at the bottom of the main housing via a space formed between the split-flow bar and the filtration sleeve and be discharged from a funnel-shape outlet of the outlet housing, and (8) the mixing and agitation action causes extraneous matters to be pushed from the cylindrical filtration screen into an upper elliptical opening and a lower round opening of the residue-removing rod, and the hydraulic cylinder pushes the residue-removing rod outward periodically or when a certain amount of the extraneous matters has been accumulated, thereby allowing the extraneous matters accumulated inside the elliptical opening and round opening to be discharged from the main housing.
