[0021] In this embodiment: sewage enters the sedimentation tank 1 for sedimentation. When the sludge is removed, the parts in the scraping mechanism 6 cooperate to scrape the sludge into the sludge tank 2 and start the sludge pump 4. The sludge pump 4 operates to extract the sludge in the sludge tank 2 through the sludge suction pipe 3. At the same time, when the sludge passes through the filter frame 5, the filter frame 5 filters the debris in the sludge to prevent the debris from entering the sludge suction pipe 3.

[0022] Please refer to Figures 1 to 5 The scraping mechanism 6 includes a mounting seat 601, which is symmetrically fixedly connected to the top of the sedimentation tank 1. The outer wall of the mounting seat 601 is provided with a movable groove 602. A motor 603 is installed at one end of the mounting seat 601. The output end of the motor 603 is connected to a first threaded rod 604. The inner wall of the movable groove 602 is slidably connected to a movable frame 606. The first threaded rod 604 runs through the movable frame 606. A scraper 607 is arranged below the movable frame 606. The scraping mechanism 6 also includes a vertical groove 608, which is provided on the outer wall of the movable frame 606. The inner wall of the vertical groove 608 A limiting groove 609 is provided, and a connecting frame 610 is fixedly connected to the top of the scraper 607. A slot 611 is provided on the outer wall of the connecting frame 610. The connecting frame 610 is symmetrically and slidably connected to a limiting block 612 inside. One end of the limiting block 612 extends out of the connecting frame 610, and the other end of the limiting block 612 is fixedly connected to an elastic sheet 613. The connecting frame 610 is internally and slidably connected to a pushing frame 614. The top of the pushing frame 614 is located below the limiting block 612, and the bottom end of the pushing frame 614 extends to the inner cavity of the slot 611. The top of the filter frame 5 is fixedly connected to an insertion rod 605.

[0023] In this embodiment: when scraping the sludge, the movable frame 606 is initially located at one end of the sedimentation tank 1 away from the sludge tank 2; the pushing frame 614 is pushed to move, and the displacement of the pushing frame 614 pushes the limit block 612 to move, causing the elastic sheet 613 to be squeezed, and the limit block 612 moves into the connecting frame 610, and the connecting frame 610 is inserted into the vertical groove 608, and then the pushing frame 614 is released, and the limit block 612 is engaged into the limit groove 609 by the elastic force of the elastic sheet 613, and then the connecting frame 610 is released, and the connecting frame 610 can slide in the vertical groove 608, and the scraper 607 falls into the bottom end of the inner cavity of the sedimentation tank 1 due to gravity, and the installation of the scraper 607 on the movable frame 606 is completed.

[0024] After completion, start the motor 603, and the operation of the motor 603 drives the first threaded rod 604 to rotate. The rotation of the first threaded rod 604 drives the movable frame 606 to slide in the movable groove 602. The displacement of the movable frame 606 drives the scraper 607 to move through the connecting frame 610. The displacement of the scraper 607 scrapes the bottom end of the inner cavity of the sedimentation tank 1, and the sludge at the bottom of the sedimentation tank 1 is scraped into the sludge tank 2; when the scraper 607 approaches the sludge tank 2, the insertion rod 605 is inserted into the slot 611, and the insertion rod 605 contacts the pushing frame 614, pushing the pushing frame 614 to move, and the displacement of the pushing frame 614 pushes the limit block 612 to move out of the limit slot 609. When the motor 603 runs and drives the movable When the frame 606 moves in the reverse direction, the connecting frame 610 is separated from the movable frame 606, so that the scraper 607 remains above the filter frame 5, preventing the movable frame 606 from driving the debris accumulated on the filter frame 5 to spread backward during the reverse movement. The scraper 607 stays on the filter frame 5 to surround and block the debris, thereby avoiding affecting the debris removal effect. When the parts in the lifting mechanism 7 cooperate to lift the filter frame 5, the movement of the filter frame 5 drives the scraper 607 to move. The filter frame 5, the scraper 607 and the side wall of the sludge tank 2 form a lifting and storage space for the debris during the rising process. When the filter frame 5 rises to the upper limit position, the debris can be cleared and the scraper 607 can be conveniently removed from the plug 605.

[0025] Please refer to Figures 6 to 8The lifting mechanism 7 includes a transverse plate 701, which is fixedly connected to the top of the sedimentation tank 1 and located between the two mounting seats 601. The top of the filter frame 5 is fixedly connected to a second threaded rod 702, and the outer wall of the first threaded rod 604 is fixedly connected to a first bevel gear 703. The interior of the mounting seat 601 is located on the outer wall of the first bevel gear 703 and is rotatably connected to a second bevel gear 704. One end of the second bevel gear 704 is fixedly connected to a worm 705. The top of the transverse plate 701 is rotatably connected to a worm gear 706 and a rotating seat 707. The rotating seat 707 is located on the inner ring of the worm gear 706. The worm 705 contacts the worm gear 706. A plurality of slots 708 are arranged in an annular array on the inner side of the top of the worm gear 706. The top of the rotating seat 707 is slidably connected to a block 709. The interior of the rotating seat 707 is rotatably connected to a third threaded rod 710 that runs through the block 709. The rotating seat 707 is sleeved on the outer wall of the second threaded rod 702.

[0026] In this embodiment, when the filter frame 5 needs to be lifted or lowered, the block 709 is rotated to the top of the adjacent slot 708, and then the third threaded rod 710 is rotated. The third threaded rod 710 rotates to drive the block 709 to move, and the block 709 moves into the slot 708 to fix the rotating seat 707 and the worm gear 706. At this time, the motor 603 is started, and the motor 603 drives the first threaded rod 604 to rotate, and the first threaded rod 604 rotates to drive the first bevel gear 703 to rotate, and the first bevel gear 703 rotates to drive the second bevel gear 704 to rotate, and the second bevel gear 704 rotates to drive the worm 705 to rotate, and the worm 705 rotates to drive the worm wheel 706 to rotate, and the worm wheel 706 rotates to drive the rotating seat 707 to rotate, and the rotating seat 707 rotates to drive the second threaded rod 702 to move, and the displacement of the second threaded rod 702 drives the filter frame 5 to move, so as to facilitate the lifting and lowering operation of the filter frame 5, thereby facilitating the cleaning operation of the debris in the filter frame 5.

[0027] It should be pointed out that when the filter frame 5 is lifted or lowered, the movable frame 606 is located on the side close to the horizontal plate 701. At this time, the motor 603 drives the first threaded rod 604 to rotate in the opposite direction, so that the movable frame 606 moves away from the horizontal plate 701 and returns to the initial position while realizing the lifting operation of the filter frame 5. Therefore, the filter frame 5 and the movable frame 606 will not interfere with each other during this process.
