[0015] The wastewater treatment method of the integrated papermaking wastewater treatment device comprises the following steps:

[0016] Step 1: Discharge papermaking wastewater into the flotation tank through the feed pipe, and start the motor at the same time. The motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade to rotate. The staff pours the reagent into the flotation tank, so that the stirring blade stirs the reagent and the wastewater. The rotating shaft drives the disc to rotate, and the disc drives the belt to rotate. The belt drives the rotating rod to rotate, and the rotating rod drives the semi-toothed plate to rotate. During the rotation of the semi-toothed plate, the double-sided toothed plate moves horizontally, and the double-sided toothed plate drives the fixed shell to move, and the fixed shell drives the filter hole scraper shell to move. When the half-toothed plate rotates halfway and no longer contacts the double-sided toothed plate, the teeth of the other half-toothed plate will mesh with the other side of the double-sided toothed plate, so that the double-sided toothed plate drives the fixed shell to move in the opposite direction, and the fixed shell drives the filter hole scraper shell to move in the opposite direction;

[0017] Step 2: When the fixed shell is away from the top cover, it is limited by the fixed plate, the polyester rope is stretched, the polyester rope drives the slider to slide inside the fixed shell, the slider drives the concave shell to move, the concave shell drives the conical cleaning plate to move, when the concave shell moves, the concave shell drives the screw rod to move, the screw rod drives the gear to move, the gear will come into contact with the single-sided toothed plate during the movement, the gear will rotate due to the contact of the teeth of the single-sided toothed plate, and the gear will drive the screw rod to rotate. Because the threaded block is limited inside the concave shell, the threaded block will drop during the rotation of the screw rod, and the threaded block drives the flexible cleaning plate to drop;

[0018] Step 3: When the threaded block falls, the threaded block will come into contact with the airbag, so that the airbag is squeezed, and the airflow inside the airbag enters the inside of the bent pipe. The airflow pushes the impact rod inside the bent pipe, causing the impact rod to slide. During the sliding process, the impact rod will come into contact with the outer wall of the filter hole scraper shell, and during the movement of the impact rod, the impact rod drives the pull rope to move, and the pull rope drives the square bar to move, so that the square bar moves toward the concave shell. During the movement of the square bar, the sliding rod is driven to move, and the sliding rod can push the conical cleaning plate in the concave shell during the movement;

[0019] Step 4: When the rotating rod rotates, the special-shaped groove allows the rotating rod to drive the limit rod to perform reciprocating lifting and lowering movements, the limit rod drives the round sleeve to perform reciprocating lifting and lowering movements, the round sleeve drives the square sleeve plate to perform reciprocating lifting and lowering movements, the square sleeve plate drives the connecting shell to perform reciprocating lifting and lowering movements, the connecting shell drives the scraper bar to perform reciprocating lifting and lowering movements, when one of the filter hole scraper shells moves to the bottom of the motor, the lifting of the scraper bar will come into contact with the back side of the filter hole scraper shell, and when the square sleeve plate moves downward, the square sleeve plate drives the traction buckle rope to move downward, the traction buckle rope is stretched, and drives the polyester rope to move downward.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention discharges papermaking wastewater into the interior of the flotation tank through the feed pipe, and at the same time starts the motor, the motor drives the rotating shaft to rotate, the rotating shaft drives the stirring blade to rotate, the staff pours the reagent into the interior of the flotation tank, the stirring blade stirs the reagent and the wastewater to generate bubbles, so that the impurities in the wastewater and the bubbles can float to the top of the wastewater together, the rotating shaft drives the disc to rotate, the disc drives the belt to rotate, the belt drives the rotating rod to rotate, the rotating rod drives the semi-toothed plate to rotate, during the rotation of the semi-toothed plate, the double-sided toothed plate is moved horizontally, the double-sided toothed plate drives the fixed shell to move, the fixed shell drives the filter hole The scraper shell moves to push the impurities floating on the wastewater to scrape and filter the impurities. At the same time, when the filter holes on the outer wall of the filter scraper shell come into contact with the impurities, the water in the impurities will pass through the filter holes into the interior of the filter scraper shell, preventing the water and the impurities from being scraped and filtered together, thereby enhancing the effect of wastewater treatment. Moreover, when the half tooth plate rotates halfway and no longer contacts the double-sided tooth plate, the teeth of the other half tooth plate will engage with the other side of the double-sided tooth plate, so that the double-sided tooth plate drives the fixed shell to move in the reverse direction, and the fixed shell drives the filter scraper shell to move in the reverse direction, thereby improving the scraping and filtering efficiency of the filter scraper shell for impurities.

[0022] (2) According to the present invention, when the fixed shell is away from the top cover, the polyester rope is stretched due to the limitation of the fixed plate, and the polyester rope drives the slider to slide inside the fixed shell, and the slider drives the concave shell to move, and the concave shell drives the conical cleaning plate to move. During the movement of the conical cleaning plate, the outer wall of the filter hole scraper shell can be cleaned, and the impurities are prevented from being attached to the outer surface of the filter hole scraper shell during the process of scraping impurities by the filter hole scraper shell, thereby improving the service life of the filter hole scraper shell. During the movement of the concave shell, the concave shell drives the screw rod to move, and the screw rod drives the gear to move. During the movement of the gear, it will come into contact with the single-sided toothed plate, and the gear will rotate due to the contact of the teeth of the single-sided toothed plate, and the gear will drive the screw rod to rotate. Because the threaded block is limited inside the concave shell, the threaded block will descend during the rotation of the screw rod, and the threaded block will drive the flexible cleaning plate to descend. During the descent of the flexible cleaning plate, the scraping surface of the conical cleaning plate will be cleaned to prevent a large amount of impurities from attaching to the scraping surface of the conical cleaning plate after working for a long time, affecting the scraping efficiency of the conical cleaning plate, and further improving the scraping effect of the conical cleaning plate on the filter hole scraper shell.

[0023] (3) According to the present invention, when the threaded block falls, the threaded block will come into contact with the airbag, causing the airbag to be squeezed, and the airflow inside the airbag enters the interior of the bent pipe. The airflow pushes the impact rod inside the bent pipe, causing the impact rod to slide. During the sliding process, the impact rod will come into contact with the outer wall of the filter hole scraper shell, and impact the filter hole surface of the filter hole scraper shell, causing impurities attached to the filter hole surface of the filter hole scraper shell to fall off, further improving the cleaning effect of the device on the filter hole surface of the filter hole scraper shell, and during the movement of the impact rod, the impact rod drives the pull rope to move, and the pull rope drives the square bar to move, so that the square bar moves closer to the concave shell, and the square bar moves during the movement. The sliding rod can push the conical cleaning plate in the concave shell during the movement. The conical cleaning plate is pushed, so that the conical cleaning plate and the filter hole surface of the filter hole scraper shell fit more closely, thereby improving the scraping effect of the conical cleaning plate on the filter hole scraper shell.

[0024] (4) According to the present invention, when the rotating rod rotates, the special-shaped groove is set, so that the rotating rod can drive the limit rod to perform reciprocating lifting and lowering movements, the limit rod drives the round sleeve to perform reciprocating lifting and lowering movements, the round sleeve drives the square sleeve plate to perform reciprocating lifting and lowering movements, the square sleeve plate drives the connecting shell to perform reciprocating lifting and lowering movements, and the connecting shell drives the scraper strip to perform reciprocating lifting and lowering movements. When one of the filter hole scraper shells moves to the bottom of the motor, the lifting and lowering of the scraper strip will come into contact with the back side of the filter hole scraper shell, preventing a large amount of impurities from adhering to the back side of the filter hole scraper shell, further improving the working life of the filter hole scraper shell, and when the square sleeve plate moves downward, the square sleeve plate drives the traction buckle rope to move downward, the traction buckle rope is stretched, and drives the polyester rope to move downward, thereby increasing the tension on the polyester rope, and increasing the force of the polyester rope to drive the slider to slide inside the fixed shell, so that the movement of the slider is more stable, preventing the slider from getting stuck during movement, and indirectly improving the scraping efficiency of the device.

[0055] Step 2: When the fixed shell 654 is away from the top cover 3, the polyester rope 661 is stretched due to the limitation of the fixed plate 655, and the polyester rope 661 drives the slider 662 to slide inside the fixed shell 654, and the slider 662 drives the concave shell 665 to move, and the concave shell 665 drives the conical cleaning plate 6610 to move. When the concave shell 665 moves, the concave shell 665 drives the screw rod 666 to move, and the screw rod 666 drives the gear 667 to move. During the movement of the gear 667, it will contact the single-sided tooth plate 664, and the gear 667 will rotate due to the contact of the teeth of the single-sided tooth plate 664, and the gear 667 drives the screw rod 666 to rotate. Because the threaded block 668 is limited inside the concave shell 665, the threaded block 668 will descend during the rotation of the screw rod 666, and the threaded block 668 drives the flexible cleaning plate 669 to descend;

[0056] Step 3: When the threaded block 668 falls, the threaded block 668 will come into contact with the airbag 671, so that the airbag 671 is squeezed, and the airflow inside the airbag 671 enters the inside of the curved pipe 672, and the airflow pushes the impact rod 674 inside the curved pipe 672, so that the impact rod 674 slides, and the impact rod 674 will come into contact with the outer wall of the filter hole scraper shell 656 during the sliding process, and the impact rod 674 will drive the pull rope 675 to move during the movement of the impact rod 674, and the pull rope 675 will drive the square bar 676 to move, so that the square bar 676 moves toward the direction of the concave shell 665, and the square bar 676 will drive the sliding rod 677 to move during the movement, and the sliding rod 677 can push the conical cleaning plate 6610 in the concave shell 665 during the movement;

[0057] Step 4: When the rotating rod 651 rotates, the special-shaped groove 681 is set so that the rotating rod 651 can drive the limiting rod 682 to perform reciprocating lifting and lowering movements, the limiting rod 682 drives the round sleeve 684 to perform reciprocating lifting and lowering movements, the round sleeve 684 drives the square sleeve plate 685 to perform reciprocating lifting and lowering movements, the square sleeve plate 685 drives the connecting shell 686 to perform reciprocating lifting and lowering movements, the connecting shell 686 drives the scraper bar 689 to perform reciprocating lifting and lowering movements, when one of the filter hole scraper shells 656 moves to the bottom of the motor 4, the lifting of the scraper bar 689 will come into contact with the back side of the filter hole scraper shell 656, and when the square sleeve plate 685 moves downward, the square sleeve plate 685 drives the traction buckle rope 687 to move downward, the traction buckle rope 687 is stretched, and drives the polyester rope 661 to move downward.

[0058] When in use, when the threaded block 668 falls, the threaded block 668 will come into contact with the airbag 671, so that the airbag 671 is squeezed, and the airflow inside the airbag 671 enters the interior of the curved pipe 672. The airflow pushes the impact rod 674 inside the curved pipe 672, causing the impact rod 674 to slide. During the sliding process, the impact rod 674 will come into contact with the outer wall of the filter hole scraper shell 656, and impact the filter hole surface of the filter hole scraper shell 656, so that impurities attached to the filter hole surface of the filter hole scraper shell 656 fall off, further improving the cleaning effect of the device on the filter hole surface of the filter hole scraper shell 656, and the impact During the movement of the striking rod 674, the impact rod 674 drives the pull rope 675 to move, and the pull rope 675 drives the square bar 676 to move, so that the square bar 676 moves closer to the concave shell 665. During the movement of the square bar 676, it drives the sliding rod 677 to move. During the movement, the sliding rod 677 can push the conical cleaning plate 6610 in the concave shell 665. The conical cleaning plate 6610 is pushed, so that the conical cleaning plate 6610 and the filter hole surface of the filter hole scraper shell 656 fit more closely, thereby improving the scraping effect of the conical cleaning plate 6610 on the filter hole scraper shell 656.

[0059] When the rotating rod 651 rotates, the special-shaped groove 681 is set, so that the rotating rod 651 can drive the limiting rod 682 to perform reciprocating lifting and lowering motion, the limiting rod 682 drives the round sleeve 684 to perform reciprocating lifting and lowering motion, the round sleeve 684 drives the square sleeve plate 685 to perform reciprocating lifting and lowering motion, the square sleeve plate 685 drives the connecting shell 686 to perform reciprocating lifting and lowering motion, and the connecting shell 686 drives the scraping strip 689 to perform reciprocating lifting and lowering motion. When one of the filter hole scraping shells 656 moves to the bottom of the motor 4, the lifting of the scraping strip 689 will come into contact with the reverse side of the filter hole scraping shell 656 to prevent A large amount of impurities are attached to the back side of the filter hole scraper shell 656, which further improves the service life of the filter hole scraper shell 656. When the square sleeve plate 685 moves downward, the square sleeve plate 685 drives the traction buckle rope 687 to move downward, and the traction buckle rope 687 is stretched, driving the polyester rope 661 to move downward, thereby increasing the tension on the polyester rope 661 and the force of the polyester rope 661 to drive the slider 662 to slide inside the fixed shell 654, making the movement of the slider 662 more stable, preventing the slider 662 from getting stuck during the movement, and indirectly improving the scraping efficiency of the device.
