[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a high-efficiency sewage treatment filtration device, including a sewage tank 4, an inlet pipe 1 connected to one side of the top of the sewage tank 4, and an mounting plate 3 connected to the other side of the top of the sewage tank 4. A motor 2 is mounted on one side of the mounting plate 3, the output shaft of the motor 2 passes through the sewage tank 4, and the output shaft of the motor 2 is connected to a collection device 7. The collection device 7 includes a filter plate 704, a rotating shaft 701 rotatably connected inside the filter plate 704, the top end of the rotating shaft 701 being connected to the output shaft of the motor 2, and a fixing ring 702 connected to the surface of the rotating shaft 701. Two cleaning plates 703 are connected to the surface of the fixing ring 702, and the cleaning plates 703 are in contact with the surface of the filter plate 704. A filter cylinder 706 is provided inside the sewage tank 4, the bottom of the filter cylinder 706 is connected to an outlet pipe 707, and the top of the filter cylinder 706 is connected to... The filter plate 704 is connected to the bottom, and the other end of the outlet pipe 707 extends out of the sewage tank 4. The sewage tank 4 is provided with multiple support legs 5 at the bottom and an observation window 6 on the surface of the sewage tank 4. The filter plate 704 is provided with a placement groove 708 on one side of the top. A collection box 705 is connected in the placement groove 708, and a groove 714 is opened at the bottom of the placement groove 708. The collection box 705 is provided with an internal groove 713 at the bottom. A fixing rod 709 is connected in the internal groove 713. A sliding groove is opened on one side of the fixing rod 709, and a sliding rod 711 is slidably connected in the sliding groove. A first spring 710 is sleeved on the surface of the sliding rod 711, and a connecting block 712 is connected to the other end of the sliding rod 711. The two ends of the first spring 710 are connected to one side of the fixing rod 709 and one side of the connecting block 712, respectively. One side of the connecting block 712 is inserted into the groove 714.

[0028] In a specific implementation, wastewater is discharged into the wastewater tank 4 through the inlet pipe 1. The wastewater is pre-treated by the filter plate 704, causing larger debris to remain on its surface. The motor 2 is then started, and its output shaft drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the fixed ring 702 to rotate, which in turn drives the cleaning plate 703 to rotate around the rotating shaft 701. The cleaning plate 703 has a cleaning brush at its bottom, which cleans the larger debris from the top of the filter plate 704, sweeping it into the collection box 705 to prevent blockage and ensure proper filtration. The collection box 705 is then placed into the placement groove 708. The connecting block 712 generates a reaction force by pressing against the inner wall of the placement groove 708. The first spring 710 is compressed, causing the sliding rod 711 to slide inside the fixed rod 709. This, in turn, causes the connecting block 712 to retract into the built-in groove 713, making the collection box 705 fit tightly against the placement groove 708. When the collection box 705 moves to the bottom of the placement groove 708, the connecting block 712 extends outward due to the rebound force of the first spring 710, thus partially engaging with the groove 714. This provides a simple limit on the collection box 705 without affecting its removal. When the collection box 705 is full of garbage, it can be easily removed for cleaning. The wastewater tank 4 has multiple support legs 5 at the bottom, which helps maintain the stability of the filtration device. An observation window 6 is provided to facilitate observation of the filtration process inside the wastewater tank 4.

[0029] A cleaning device 8 is connected to the surface of the rotating shaft 701. The cleaning device 8 includes multiple connecting rods 802, and each of the multiple connecting rods 802 is connected to a telescopic rod 804 on the side away from the rotating shaft 701. A second spring 803 is sleeved on the surface of the telescopic rod 804, and a fixing block 805 is connected to the other end of the telescopic rod 804. The two ends of the second spring 803 are respectively connected to one side of the connecting rod 802 and one side of the fixing block 805. A connecting plate 806 is connected to the other end of the fixing block 805, and a brush 801 is connected to the other side of the connecting plate 806.

[0030] In a specific implementation, the motor 2 is started, and the output shaft of the motor 2 drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the connecting rod 802 to rotate, the connecting rod 802 drives the telescopic rod 804 to rotate, the telescopic rod 804 drives the fixed block 805 to rotate, and the fixed block 805 drives the connecting plate 806 to rotate. By setting the telescopic rod 804, the second spring 803 is supported, preventing the second spring 803 from bending when compressed, which would affect the operation of the device. At the same time, the telescopic rod 804 also supports the connecting plate 806. The connecting plate 806 drives the brush 801 to rotate. By setting the second spring 803, the second spring 803 presses the connecting plate 806 due to its rebound force, thereby driving the brush 801 to press against the inner wall of the filter cylinder 706, so that the brush 801 fits tightly against the filter cylinder 706. Then, the brush 801 extends into the filter cylinder 706 and clears it, preventing garbage from clogging the filter cylinder 706 and affecting the filtration effect of the filter cylinder 706.

[0031] Working principle: When in use, start motor 2. The output shaft of motor 2 drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the fixed ring 702 to rotate. The fixed ring 702 drives the cleaning plate 703 to rotate around the rotating shaft 701. The bottom of the cleaning plate 703 is equipped with a cleaning brush 801, which sweeps larger debris into the collection box 705, preventing larger debris from clogging the filter plate 704 and affecting the filtration effect of the filter plate 704. The rotating shaft 701 drives the connecting rod 802 to rotate. The connecting rod 802 drives the telescopic rod 804 to rotate. The telescopic rod 804 drives the fixed block 805 to rotate. The fixed block 805 drives the connecting plate 806 to rotate. The connecting plate 806 drives the brush 801 to rotate, so that the brush 801 extends into the filter cylinder 706 to unclog it and prevent debris from clogging the filter cylinder 706.
