[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] As attached Figure 1 To be continued Figure 5As shown: A low-carbon, low-cost rural sewage treatment device includes a sewage treatment tank body 1. An inlet pipe 2 is fixedly connected to the upper surface of the sewage treatment tank body 1. A filter cleaning assembly 3 for filtering large pieces of debris in the sewage is installed outside the inlet pipe 2. The filter cleaning assembly 3 includes a filter plate 301 slidably connected inside the sewage treatment tank body 1. A collection chamber 4 is fixedly connected to the outer surface of the sewage treatment tank body 1, and the side of the collection chamber 4 closest to the sewage treatment tank body 1 is connected to the sewage treatment tank body 1. A set of filter holes 5 are opened on the side of the collection chamber 4 closest to the sewage treatment tank body 1. The slope and vibration of the filter plate 301 can guide the debris on the surface of the filter plate 301 to the inside of the collection chamber 4, and collect the large pieces of debris filtered from the surface of the filter plate 301 through the collection chamber 4, thereby preventing large pieces of debris from remaining on the surface of the filter plate 301 and affecting the filtration effect. The filter holes 5 have a small diameter, allowing sewage flowing into the collection chamber 4 to flow back into the sewage treatment tank body 1 through the filter holes 5, facilitating subsequent sewage treatment.

[0028] As attached Figure 1 To be continued Figure 4 As shown: The filter cleaning assembly 3 also includes a striking structure for striking the filter plate 301. The striking structure includes a rotating rod 302 rotatably connected to the inner wall of the sewage treatment tank body 1. A sleeve rod 303 is fixedly connected to the outer surface of the rotating rod 302. A set of water collection tanks 304 is fixedly installed on the outer surface of the sleeve rod 303. An incomplete gear 305 is fixedly connected to the outer surface of the rotating rod 302. A grooved rack 306 meshes with the outer surface of the incomplete gear 305. An impact block 307 is fixedly connected to the bottom surface of the grooved rack 306. A guide rail 308 is slidably connected to the inner wall of the grooved rack 306, and the outer surface of the guide rail 308 is fixed to the inner wall of the sewage treatment tank body 1. In the connection, after the sewage falls into the collection tank 304, the sleeve rod 303 will rotate due to the influence of the sewage's gravity and impact force. When the sleeve rod 303 rotates, it will drive the rotating rod 302 and the incomplete gear 305 to rotate. Utilizing the meshing between the incomplete gear 305 and the grooved rack 306, the grooved rack 306 will move upward when the incomplete gear 305 rotates until it disengages from the grooved rack 306. The grooved rack 306 will then immediately fall, causing the impact block 307 to strike the filter plate 301, thereby causing the filter plate 301 to move downward, which facilitates the vibration of the subsequent filter plate 301.

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6As shown: A vibration structure for causing the filter plate 301 to vibrate. The vibration structure includes two sleeves 309 fixedly connected to the inner wall of the sewage treatment tank body 1. A spring 310 is fixedly connected to the inner bottom wall of each sleeve 309. A damper 311 is fixedly connected to the other end of each spring 310. A movable column 312 is fixedly connected to the upper surface of each damper 311, and the outer surface of the movable column 312 is slidably connected to the inner wall of the sleeve 309. A connecting block 313 is slidably connected to the inner wall of each movable column 312, and the upper surface of the connecting block 313 is fixedly connected to the bottom surface of the filter plate 301. A bolt 314 is threadedly connected to the inner walls of each movable column 312 and the connecting block 313. Tightening the bolt 314 causes it to disengage from the inside of the connecting block 313. Afterwards, the limiting position on the connecting block 313 is released, and the filter plate 301 can then be removed for maintenance and replacement, which is convenient and quick. When the filter plate 301 moves downward, it will drive the moving column 312 to move in the same direction and compress the spring 310. When the downward force of the filter plate 301 ends, the spring 310 immediately rebounds and pushes the moving column 312 and the filter plate 301 to reset. At the same time, the damper 311 can absorb part of the force released by the spring 310 and release it, thereby causing the filter plate 301 to vibrate, which can shake out the sludge in the filter holes of the filter plate 301, thus achieving the effect of cleaning the filter holes of the filter plate 301, avoiding the sludge from clogging the filter holes of the filter plate 301 and affecting the filtration effect of the filter plate 301, and improving the practicality of the device.

[0030] As attached Figure 1 and attached Figure 2As shown: A connecting pipe 8 is fixedly connected to the outer surface of the sewage treatment tank body 1. The other end of the connecting pipe 8 is fixedly connected to the reaction tank body 9. A dosing pipe 10 is fixedly connected to the upper surface of the reaction tank body 9. A drain pipe 11 is fixedly connected to the outer surface of the reaction tank body 9. A guide plate 6 is provided on the inner bottom wall of the sewage treatment tank body 1. A sludge tank 7 is fixedly connected to the outer surface of the sewage treatment tank body 1, and the side of the sludge tank 7 closest to the sewage treatment tank body 1 is connected to the sewage treatment tank body 1. A first valve 12 is installed on the outer surface of the connecting pipe 8. A second valve 13 is installed on the outer surface of the drain pipe 11. A filter screen 14 is fixedly connected to the inner wall of the drain pipe 11. Closing the first valve 12... The sludge in the sewage inside the sewage treatment tank body 1 settles at the bottom of the sewage treatment tank body 1. Under the guidance of the guide plate 6, the sludge at the bottom of the sewage treatment tank body 1 flows into the sludge tank 7. After the sedimentation is completed, the sewage inside the sewage treatment tank body 1 will enter the reaction tank body 9 through the connecting pipe 8 under the action of pressure difference. Then, the chemical dosing pipe 10 will be used to add chemicals into the reaction tank body 9 to treat the sewage. After the treatment is completed, the second valve 13 will be opened to discharge the treated clean water. The filter screen 14 can filter the impurities in the sewage and chemical reaction inside the reaction tank body 9, thereby ensuring the cleanliness of the discharged clean water.

[0031] Working principle: When cleaning the sludge inside the filter holes of filter plate 301, sewage is first discharged into the sewage treatment tank body 1 through the sewage inlet pipe 2. After the sewage falls into the collection tank 304, the sleeve rod 303 will rotate due to the gravity and impact force of the sewage. When the sleeve rod 303 rotates, it will drive the rotating rod 302 and the incomplete gear 305 to rotate. Utilizing the meshing between the incomplete gear 305 and the grooved rack 306, the grooved rack 306 will move upward when the incomplete gear 305 rotates. When the incomplete gear 305 rotates to the point where it disengages from the grooved rack 306, the grooved rack 306 will immediately fall, driving the impact block 307 to impact the filter plate 301. The tapping action causes the filter plate 301 to move downwards. As the filter plate 301 moves downwards, it drives the moving column 312 to move in the same direction and compresses the spring 310. When the downward force on the filter plate 301 ends, the spring 310 immediately rebounds, pushing the moving column 312 and the filter plate 301 back to their original positions. At the same time, the damper 311 absorbs and releases part of the force released by the spring 310, causing the filter plate 301 to vibrate. This vibrates the sludge out of the filter holes of the filter plate 301, thus cleaning the filter holes of the filter plate 301 and preventing sludge from clogging the filter holes and affecting the filtration effect of the filter plate 301, thereby improving the practicality of the device.
