[0002] Rural domestic sewage in my country originates from wastewater discharged during daily life, including feces and urine, ware washing, bathing, laundry, and kitchen and room cleaning. The pollutants are relatively simple, with high concentrations of organic matter and nitrogen and phosphorus, but generally free of heavy metals and toxic substances. Among these, CN 217567843 U discloses a filtration and separation device for rural domestic sewage treatment, comprising a sewage treatment tank. One end of the sewage treatment tank is fixedly connected to a motor housing, the inner wall of the motor housing is fixedly connected to a motor, one end of the motor is fixedly connected to a transmission rod, the outer wall of the transmission rod is fixedly connected to four mesh plates, the inner wall of the sewage treatment tank is fixedly connected to an inclined plate, the middle of the inner wall of the sewage treatment tank is fixedly connected to a partition plate, and one side of the partition plate is fixedly connected to a filter plate. With the sewage treatment tank, when sewage enters, impurities begin to settle to the bottom along the inclined plate. The motor drives the transmission rod to rotate, thereby rotating the mesh plates and transferring the sediment into the space formed by the inclined plate and the inner wall of the sewage treatment tank. Opening the valve at the discharge outlet facilitates the discharge and collection of impurities.

[0003] The above solution has the following shortcomings in actual operation: When the filter screen is used to collect impurities in the sewage, the filtration effect will be affected when there are too many impurities in the filter screen. As a result, the filter screen will not only contain a large amount of impurities but also accumulate a large amount of sewage, causing the filter screen to bear too much weight. It will not only be difficult to remove but may also break. Utility Model Content

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

[0012] Reference Figures 1-4 A rural sewage filtration and separation device includes a barrel body 1, a filter barrel 101 fixedly connected to the inner wall of the barrel body 1, a dirt removal component 2 installed on the side wall of the filter barrel 101 for removing impurities from the inner wall of the filter barrel 101, and a sewage discharge component 3 installed at the bottom of the filter barrel 101 for discharging impurities. The device also includes: The impurity removal component 2 includes a first servo motor 201, which is fixedly installed on the top of the barrel 1. The output end of the first servo motor 201 is fixedly connected to a first rotating shaft 202, which passes through the filter barrel 101. Multiple sets of cutters 203 are fixedly connected to the side wall of the first rotating shaft 202. A brush 204 is fixedly connected to the end of the cutter 203, and the brush 204 is in contact with the inner wall of the filter barrel 101. A water inlet pipe 205 is fixedly connected to the top of the barrel 1, and the water inlet pipe 205 is connected to the filter barrel 101. A water outlet assembly 206 is fixedly connected to the bottom of the side wall of the barrel 1. It should be noted that: by injecting sewage into the inner cavity of the filter barrel 101 of the inner cavity of the barrel 1, the filter barrel 101 filters out the impurities in the sewage. The filtered water is discharged through the water outlet component 206, which can drive the first servo motor 201. The first servo motor 201 drives the cutter 203 to rotate through the first rotating shaft 202. During the rotation, the cutter 203 can cut large pieces of impurities to prevent them from being too large and clogging the subsequent sewage discharge component 3. At the same time, the rotation of the cutter 203 can drive the brush 204 to rotate. Since the brush 204 is in contact with the inner wall of the filter barrel 101, the rotating brush 204 can remove the impurities adhering to the inner wall of the filter barrel 101, preventing the filter barrel 101 from being blocked and affecting the filtration effect.

[0013] Reference Figures 1-4 The sewage discharge component 3 includes a first connecting pipe 301, which is fixedly installed at the bottom of the filter bucket 101, and a second connecting pipe 302 is fixedly connected to the bottom end of the first connecting pipe 301. A sensor valve 303 is fixedly connected to the bottom of the side wall of the first connecting pipe 301, and a first spiral blade 304 is fixedly connected to the side wall of the first rotating shaft 202 located in the inner cavity of the first connecting pipe 301. A second servo motor 305 is fixedly connected to the side wall of the second connecting pipe 302, a second rotating shaft is fixedly connected to the output end of the second servo motor 305, and a second spiral blade 306 is fixedly connected to the side wall of the second rotating shaft. It should be noted that after impurities are filtered by the filter canister 101, they will fall under the influence of gravity. At the same time, the first rotating shaft 202 can drive the first spiral blade 304 to rotate. The rotating first spiral blade 304 can transport the impurities to the bottom of the first connecting pipe 301. Since the bottom of the first connecting pipe 301 is equipped with a sensor valve 303, sewage will not leak out. When too much impurity accumulates at the bottom of the first connecting pipe 301, the sensor valve 303 can open the first connecting pipe 301. At this time, the impurities accumulated at the bottom of the first connecting pipe 301 will fall into the inner cavity of the second connecting pipe 302, and at the same time drive the second servo motor 305. The second servo motor 305 drives the second rotating shaft to rotate. The second rotating shaft drives the second spiral blade 306 to rotate, which can discharge the impurities from the second connecting pipe 302, thereby removing the impurities filtered into the inner cavity of the filter canister 101.

[0014] Reference Figures 1-4 The bottom of the filter bucket 101 is set to be inclined toward the first connecting pipe 301, and a connecting column is fixedly connected to the side wall of the first rotating shaft 202; A scraper 4 is fixedly connected to the end of the connecting column, and the scraper 4 is in contact with the bottom of the inner wall of the filter barrel 101; It should be noted that the bottom of the filter barrel 101 is set to tilt towards the first connecting pipe 301, which can ensure that impurities fall into the inner cavity of the first connecting pipe 301. At the same time, when the first rotating shaft 202 rotates, it drives the scraper 4 to rotate through the connecting column, which can prevent impurities from adhering to the bottom of the filter barrel 101.

[0015] Operation method: By injecting sewage into the inner cavity of the filter barrel 101 of the inner cavity of the barrel 1, the filter barrel 101 filters out the impurities in the sewage. The filtered water is discharged through the water outlet assembly 206. The first servo motor 201 can drive the first servo motor 201, which drives the cutter 203 to rotate through the first rotating shaft 202. During the rotation, the cutter 203 can cut large pieces of impurities. At the same time, the rotation of the cutter 203 can drive the brush 204 to rotate. Since the brush 204 is in contact with the inner wall of the filter barrel 101, the rotating brush 204 can remove the impurities adhering to the inner wall of the filter barrel 101, so as to avoid the filter barrel 101 being blocked and affecting the filtration effect. After being filtered by the filter canister 101, the impurities fall under the influence of gravity. At the same time, the first rotating shaft 202 drives the first spiral blade 304 to rotate. The rotating first spiral blade 304 can transport the impurities to the bottom of the first connecting pipe 301. Since a sensor valve 303 is provided at the bottom of the first connecting pipe 301, the sewage will not leak out. When too many impurities accumulate at the bottom of the first connecting pipe 301, the sensor valve 303 can open the first connecting pipe 301. At this time, the impurities accumulated at the bottom of the first connecting pipe 301 will fall into the inner cavity of the second connecting pipe 302. Simultaneously, the second servo motor 305 is driven. The second servo motor 305 drives the second rotating shaft to rotate. The second rotating shaft drives the second spiral blade 306 to rotate, which can discharge the impurities from the second connecting pipe 302, thereby removing the impurities filtered from the inner cavity of the filter canister 101.
