The paper pulp wastewater treatment equipment for waste paper recycling according to claim 1, characterized in that: A first support rod (71) is fixedly connected to the rear end of the collecting box (15); a driving motor (72) is installed on the inner side of the first support rod (71); an output shaft of the driving motor (72) is fixedly connected to a first roller (76); one end of the first filter plate (4) is fixedly connected to two groups of first extension rods (73); the other end of the first filter plate (4) is fixedly connected to two groups of second extension rods (74); two groups of second rollers (75) are rotatably connected between the two groups of second extension rods (74); the first roller (76) is rotatably connected between the two groups of push rods (84); two groups of belts (77) are provided on the outer sides of the first roller (76) and the second roller (75); a cross bar (78) is fixedly connected between the two groups of belts (77); the belts (77) are sleeved on the outer side of the first filter plate (4); and the cross bar (78) is in contact with the first filter plate (4).

5. The paper pulp wastewater treatment equipment for waste paper recycling according to claim 1, characterized in that: The inner side of the guard plate (3) is rotatably connected to a third rotating drum (10), the outer side of the third rotating drum (10) is fixedly connected to a second support rod (11), the upper end of the second support rod (11) is rotatably connected to a striking rod (12), the inner side of the third rotating drum (10) is rotatably connected to a third rotating shaft (13), the third rotating shaft (13) is fixedly connected to the guard plate (3), a third elastic sheet (14) is arranged on the outer side of the third rotating shaft (13), and the third elastic sheet (14) is located on the inner side of the third rotating drum (10).

6. A method for treating waste paper recycling pulp wastewater, applied to a waste paper recycling pulp wastewater treatment device as claimed in any one of claims 1 to 5, characterized in that: include: Step 1: using a water pipe to make waste water flow down from the upper end of the first filter plate (4), using the first filter plate (4) to filter the water, starting the drive motor (72) to drive the first roller (76) to rotate, and then driving the belt (77) to rotate, so that the cross bar (78) scrapes the waste filtered from the first filter plate (4) and makes the waste fall onto the second filter plate (85); Step 2: Start the hydraulic rod (81) to push the jamming shell (82) to slide on the upper end of the guard plate (3), and use the push rod (84) to push the second filter plate (85) to tilt, so that the waste on the second filter plate (85) slides to the inner side of the collection box (15). At this time, the jamming shell (82) drives the lever (62) to rotate, pushing the connecting rod (63) to move, so that the first rotating rod (64) is offset, and then drives the baffle (65) to rotate, so that the angle between the baffle (65) and the first filter plate (4) is reduced, thereby slowing down the water flow speed; Step 3: The second filter plate (85) tilts upward, which can push the pressure roller (92) to drive the second rotating rod (91) to move upward, and at the same time, the pressure roller (92) rotates on the connecting shaft (93), so that the pressure roller (92) squeezes out the water in the waste material, and the second filter plate (85) moves downward so that the hook (96) will clamp the ratchet (95), so that the pressure roller (92) stops rotating, and the waste material on the second filter plate (85) is scraped off by the pressure arc (94); Step 4: The striking rod (12) is moved by the cross bar (78) to drive the second support rod (11) to rotate the third rotating drum (10), and the striking rod (12) is used to strike the lower end of the first filter plate (4) to increase the filtering efficiency of the first filter plate (4).
