The scraper 19 is located below the translation rod 20, a protrusion 21 is fixedly installed on the left side of the translation rod 20, and a second protrusion 22 is fixedly installed on the top of the translation block 18. The second protrusion 22 is connected to the protrusion 21 by a connecting spring 23. The contraction of the connecting spring 23 can facilitate the translation movement of the translation rod 20 and drive the arc-shaped fitting plate 26 to move to the right, thereby preventing the arc-shaped fitting plate 26 from being unable to fit with the column 36 when the arc-shaped fitting plate 26 moves to the back side close to the filter plate 16.

[0034] See also Figure 3-Figure 4The right side of the translation rod 20 is fixedly installed with a U-shaped block 24, and a rotating rod 25 is rotatably installed in the U-shaped groove on the U-shaped block 24.

[0040] See also Figure 1-Figure 7 A circular slide groove is provided on the inner wall of the top end of the cleaning tank 1, and the diameter of the circular slide groove is the same as the diameter of the support column 31, so as to provide support for the bottom end of the support column 31 and ensure that the second connecting plate 30 can make a circular motion.

[0041] See also Figure 1-Figure 7 A connecting plate 11 is installed on the driving gear 10, and the connecting plate 11 is fixedly connected to an arc-shaped fixed block 4.

The outer wall of the gear ring that is one of the structures composed of the fixed gear ring 9 and the driving gear 10 is provided with a plurality of teeth that can mesh with each other, so that the fixed gear ring 9 can be driven to rotate by the driving gear 10 during use.

[0042] The implementation principle of this embodiment is as follows: when in use, the electrical appliance on the sewage treatment device is first started by an external power supply, and the sewage enters the cleaning tank 1 through the water inlet pipe 2, is filtered through the filter plate 16 and the filter screen cylinder 8, and is discharged through the water outlet pipe 3. In the long-term use process, the fixed gear ring 9 is driven to rotate by the driving gear 10, and the fixed gear ring 9 drives the connecting block 29 and the scraper plate 40 to move, so that the scraper plate 40 scrapes the impurities on the surface of the filter screen cylinder 8. At this time, the reset spring in the sleeve 33 works to make the cleaning plate 35 fit the filter plate 16. The right side wall, at this time, the cleaning plate 35 continues to follow the movement of the fixed gear ring 9 to scrape off the impurities on the right side wall of the filter plate 16, and contacts the baffle plate 42 during the continuous movement of the scraper plate 40, and is scraped into the collecting tank 15 by the baffle plate 42 for collection. In the movement of the cleaning plate 35, the column 36 at the top of the cleaning plate 35 is in contact with the arc-shaped fitting plate 26. During the continuous movement of the cleaning plate 35, the arc-shaped fitting plate 26, the translation block 18, and the scraper 19 are driven to move through the column 36. At this time, the scraper 19 can scrape off the impurities on the left side of the filter plate 16.
