[0022] This utility model embodiment provides a sewage treatment tank that is easy to clean.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A wastewater treatment tank that is easy to clean includes a treatment tank 1. A water injection pipe 11 and a drain pipe 12 are fixedly connected to both ends of the treatment tank 1. Valves are fixedly connected to both the water injection pipe 11 and the drain pipe 12. Wastewater is injected into the treatment tank 1 through the water injection pipe 11 for treatment, and the treated wastewater is discharged by opening the drain pipe 12. The treatment tank 1 is equipped with a cleaning mechanism for cleaning the inner wall and the inner bottom wall of the treatment tank 1. The cleaning mechanism includes a movable frame 2 that slides inside the treatment tank 1. A fixed scraper 3 for cleaning and scraping the inner wall and the inner bottom wall of the treatment tank 1 is fixedly connected to the outer surface of the movable frame 2. Both the movable frame 2 and the fixed scraper 3 are U-shaped. The fixed scraper 3 is used to scrape and clean the inner wall and the inner bottom wall of the treatment tank 1.

[0024] Please refer to it again. Figure 1 , Figure 2 and Figure 4 The bottom of the movable frame 2 is slidably connected to a movable sleeve 4. One end of the movable sleeve 4 is provided with a crushing nail 5. By controlling the movable sleeve 4 to rise and slide at the bottom of the movable frame 2, the crushing nail 5 at one end of the movable sleeve 4 is used to crush the clumped mud layer. The crushing nail 5 is slidably connected to the bottom of the movable sleeve 4. The top of the crushing nail 5 is fixedly connected to a top plate 51. The top of the top plate 51 is fixedly connected to a spring 41. Under the action of the spring 41, the crushing nail 5 is prevented from damaging the inner bottom wall of the treatment pool 1 during the crushing process. There are multiple movable sleeves 4. The tops of multiple movable sleeves 4 are fixedly connected to each other by a connecting plate 6. The connecting plate 6 is used to drive multiple movable sleeves 4 to rise and slide together.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The movable frame 2 is equipped with a lifting mechanism that drives the movable sleeve 4 to reciprocate up and down. The lifting mechanism includes a rotating rod 7 rotatably connected to the movable frame 2. One end of the rotating rod 7 is fixedly connected to a rotating disk 71. One side of the rotating disk 71 is rotatably connected to a connecting rod 72. The other end of the connecting rod 72 is hinged to the top of the connecting plate 6 by a pin.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A fixed rack 8 is fixedly connected to the top of the treatment tank 1, and a connecting gear 9 is fixedly connected to the other end of the rotating rod 7. The connecting gear 9 meshes with the fixed rack 8. When the movable frame 2 moves horizontally, the rotating rod 7 is driven to rotate by the meshing action of the fixed rack 8 and the connecting gear 9, thereby reducing the number of drive devices used.

[0027] Please refer to it again. Figure 1 and Figure 2 The treatment tank 1 is equipped with a drive mechanism that drives the movable frame 2 to slide horizontally inside the treatment tank 1. The drive mechanism includes a screw 21 rotatably connected to the treatment tank 1. One end of the movable frame 2 is threadedly connected to the screw 21. A drive motor 22 that drives the screw 21 to rotate is fixedly connected to the treatment tank 1. The two ends of the top of the movable frame 2 are inverted U-shaped. By starting the drive motor 22, the screw 21 is driven to rotate, causing the movable frame 2 to slide horizontally back and forth inside the treatment tank 1.

[0028] Working principle: The device is installed in a suitable location and connected to the municipal power supply. Wastewater is injected into the treatment tank 1 through the water injection pipe 11 for treatment. Then, the treated wastewater is discharged by opening the drain pipe 12. The drive motor 22 is started to drive the screw 21 to rotate, which drives the movable frame 2 to slide horizontally back and forth inside the treatment tank 1. The fixed scraper 3 on the outer surface of the movable frame 2 scrapes and cleans the inner bottom wall and inner wall of the treatment tank 1. During the horizontal sliding process, the movable frame 2 drives the rotating rod 7 to rotate under the meshing action of the fixed rack 8 and the connecting gear 9. Under the connection of the rotating disk 71 and the connecting rod 72, the connecting plate 6 is pulled to slide up and down. The crushing nail 5 at one end of the movable sleeve 4 is used to crush the clumps of mud on the inner bottom wall of the treatment tank 1, so as to scrape and clean it and prevent large mud clumps from blocking the drain pipe 12 and affecting the flow of wastewater.
