DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: a sedimentation and filtration device for sewage treatment, comprising a filtration tank 1, a first motor 2, a turntable 3, an arc-shaped rotating rod 4, a brush 5, a groove plate 6, a filter mesh body 7, a fixing plate 8, a threaded rod 9, an adsorption layer 10, a second motor 11, a fixing rod 12, an eccentric wheel 13, a sliding rod 14, a fixed groove frame 15, a scraper 16 and a valve 17;

[0027] When the sedimentation and filtration device for sewage treatment is in use, as Figures 1-5 shown, when it is necessary to prevent large particles in the sewage from blocking the mesh holes, start the first motor 2 fixedly connected to the rear side of the upper end of the filtration tank 1, drive the turntable 3 fixedly connected to the front end of the first motor 2 to rotate. When the turntable 3 rotates, the arc-shaped rotating rod 4 connected to the outer side of the front end of the turntable 3 swings. The upper rear side of the arc-shaped rotating rod 4 is rotatably connected inside the filtration tank 1 to limit the arc-shaped rotating rod 4, and drives the brush 5 rotatably connected to the outer side of the lower end of the arc-shaped rotating rod 4 to move left or right. At the same time, the front and rear outer sides of the brush 5 are slidably connected to the inner side of the groove plate 6 to limit the brush 5 and brush the filter mesh body 7 closely attached to the lower end of the brush 5, which can prevent large impurity particles in the sewage from blocking the mesh holes of the filter mesh;

[0028] When it is necessary to disassemble and replace the filter mesh, rotate the threaded rod 9 internally threaded in the right end of the fixing plate 8 downward, so that the outer side of the threaded rod 9 disengages from the card slot connection between the fixing plates 8, and pull the fixing plate 8 to the right, so that the outer sides of the two ends of the fixing plate 8 disengage from the card slot connection with the filtration tank 1, and drive the filter mesh body 7 fixedly connected to the inner side of the fixing plate 8 to be pushed to the right, so that the outer side of the upper end of the filter mesh body 7 disengages from the close fit with the brush 5, and push the new fixing plate 8 to the left, so that the outer side of the left end of the fixing plate 8 is connected to the card slot inside the filtration tank 1, and rotate upward, so that the outer side of the upper end of the threaded rod 9 is threadedly connected to the filtration tank 1 and the fixing plate 8 to limit the fixing plate 8, so that the filtered sewage falls into the adsorption layer 10 and is adsorbed by the adsorption layer 10, which can prevent the filter mesh from being damaged due to the sewage containing acidic substances, and has strong practicability;

[0029] When it is necessary to prevent dirt in the sewage from sticking to the inner wall, the second motor 11 is started to drive the fixed rod 12 fixedly connected to the right end of the second motor 11. When the fixed rod 12 rotates, it drives the eccentric wheel 13 fixedly connected to the outside of the fixed rod 12 to rotate, driving the slide rod 14 rotatably connected to the inner side of the upper end of the eccentric wheel 13 to move up and down. At the same time, the outside of the slide rod 14 intermittently slides up and down inside the fixed groove frame 15, so that the scraper 16 fixedly connected to the outside of the upper end of the slide rod 14 scrapes the inner wall of the filter tank 1. The dirt after scraping falls to the bottom of the filter tank 1, and the sewage is controlled to flow out through the valve 17 installed at the lower end of the filter tank 1, which can prevent the dirt generated in the sewage from adhering to the inner wall, causing the inner wall of the sewage treatment device to age and reducing the service life of the sewage treatment device.
