[0002] In the daily lives of rural residents, various types of wastewater are generated. This wastewater contains a large amount of organic matter and pathogenic microorganisms. With the improvement of residents' living standards, the discharge of rural domestic sewage is increasing year by year. Many rural areas lack complete sewage treatment facilities, resulting in sewage being directly discharged into ditches, rivers or seeping into the ground, which will cause serious environmental pollution and health hazards. Existing rural sewage treatment devices usually use filter barrels or filter screens for filtration. The purification effect of a single filtration step is limited, the purity of sewage purification is not high, and the purified sewage will still pollute the environment.

[0003] To address the above problems, a rural domestic sewage treatment device has been developed. Utility Model Content

[0004] In order to overcome the shortcomings of existing rural sewage treatment devices that typically use filter barrels or filter screens for filtration, which have limited purification effects due to a single filtration step, low sewage purity, and the fact that the purified sewage still pollutes the environment, this utility model provides a rural domestic sewage treatment device.

The filter bucket is rotatably connected to a cover plate. Pins are slidably connected to the front and rear right sides of the cover plate, and these pins lock the filter bucket and cover plate. Support plates are connected to the front and rear of the horizontal plate. An mounting plate is rotatably connected to the horizontal plate, and the support plates support and limit the mounting plate. A storage tank is mounted on the mounting plate, and a spraying assembly is mounted on the mounting plate. The spraying assembly sprays the water purification agent from the storage tank into the treatment frame. Four sleeves are connected to the vertical plate frame, and cleaning plates are slidably connected between the sleeves. Four springs are connected between the cleaning plates and the vertical plate frame, and the springs are all located inside adjacent sleeves.

[0006] As a further preferred embodiment, the processing frame is provided with a support block that supports the water outlet plate.

[0007] As a further preferred embodiment, the left side of the upright frame is lower than the right side, which facilitates the conveying of sewage to the left side.

[0008] As a further preferred embodiment, the water outlet has three outlets.

[0009] As a further preferred embodiment, the lifting plate has a U-shaped structure.

[0010] As a further preferred embodiment, the lifting plate is provided with triangular ribs for reinforcement.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] This invention improves wastewater purification efficiency and purity through multiple filtrations, preventing wastewater from polluting the environment.

[0020] A rural domestic sewage treatment device, such as Figures 1-5 As shown, the system includes a treatment frame 1 with a support block for supporting the drain plate 2. The drain plate 2 is placed on the right side of the treatment frame 1. A vertical plate frame 3 is connected to the middle of the treatment frame 1, with the left side of the vertical plate frame 3 lower than the right side to facilitate the conveying of sewage to the left. A horizontal plate 4 is connected to the left side of the treatment frame 1. There are three outlets 5 connected to the lower left side of the treatment frame 1. A lifting plate 6 is slidably connected to the right side of the treatment frame 1. The lifting plate 6 has a U-shaped structure and triangular ribs for reinforcement. A screw rod 7 is rotatably connected to the front right side of the treatment frame 1 and is threaded to the lifting plate 6. A guide rod 8 is connected to the rear right side of the treatment frame 1 and is slidably connected to the lifting plate 6. A drive motor 9 is installed on the front middle side of the treatment frame 1, and a filter barrel is connected to the output shaft of the drive motor 9. 10. The filter bucket 10 is rotatably connected to the treatment frame 1. A cover plate 11 is rotatably connected to the filter bucket 10. Pins 12 are slidably connected to the right sides of both the front and rear parts of the cover plate 11. Pins 12 lock the filter bucket 10 and the cover plate 11. Support plates 13 are connected to both the front and rear parts of the horizontal plate 4. A mounting plate 14 is rotatably connected to the horizontal plate 4. The support plates 13 support and limit the mounting plate 14. A liquid storage tank 15 is installed on the mounting plate 14. A spraying assembly 16 is installed on the mounting plate 14. The spraying assembly 16 sprays the water purification agent in the liquid storage tank 15 into the treatment frame 1. Four sleeves 18 are connected to the vertical plate frame 3. A cleaning plate 17 is slidably connected between the sleeves 18. Four springs 19 are connected between the cleaning plate 17 and the vertical plate frame 3.

[0021] It should be noted that rural residents generate various types of wastewater in their daily lives. This wastewater contains a large amount of organic matter and pathogenic microorganisms. With the improvement of residents' living standards, the discharge of rural domestic sewage is increasing year by year. Many rural areas lack complete sewage treatment facilities, resulting in sewage being directly discharged into ditches, rivers, or seeping into the ground, causing serious environmental pollution and health hazards. This device filters domestic sewage multiple times, purifying it and preventing it from being directly discharged and polluting the environment. The sewage first enters the lifting plate 6 through the drain plate 2. When wastewater passes through the drain plate 2, it undergoes its first filtration. Impurities in the wastewater settle on the lifting plate 6. The wastewater, after the impurities have settled, enters the vertical plate 3 through the gap between the drain plate 2 and the vertical plate frame 3. The drive motor 9 is then activated, and its output shaft rotates, causing the filter barrel 10 to rotate. The filter barrel 10 performs a second filtration of the wastewater and transports it to the left. Simultaneously, the spraying assembly 16 sprays the purifying agent from the storage tank 15 onto the left side of the treatment frame 1. The purifying agent purifies the wastewater, which is then discharged through the outlet 5. Water is discharged outwards. This device filters and purifies wastewater multiple times, which helps improve wastewater purification efficiency and purity, and avoids wastewater discharge that pollutes the environment. When the sediment accumulates to a certain extent, the drain plate 2 can be removed, and the screw 7 can be rotated to move the lifting plate 6 upwards, making it easier for operators to clean the sediment on the lifting plate 6. During the secondary filtration in the filter barrel 10, contaminants may remain on the surface of the filter barrel 10. These contaminants will affect the filtration efficiency of the filter barrel 10, and these contaminants need to be cleaned in a timely manner. As the filter barrel 10 continues to rotate, the cleaning plate 17 can clean the surface of the filter barrel 10. At the same time, the buffering effect of the spring 19 allows the cleaning plate 17 to adapt to the degree of impurity accumulation on the surface of the filter barrel 10 when cleaning it, avoiding direct contact between the cleaning plate 17 and the filter plate, which could damage the filter barrel 10. Impurities may also be mixed into the inside of the filter barrel 10. The sliding pin 12 can be used to disengage the cover plate 11 from the filter barrel 10, and then the cover plate 11 can be flipped outward to unfold the filter barrel 10, making it easier for the operator to clean the impurities inside the filter barrel 10.
