Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0019] See also Figures 1 to 16 The present invention provides a technical solution: a rural domestic sewage composite ecological filtering device, comprising: a box body 11, a liquid pipe 12 is arranged on one side of the box body 11, It also includes: a processing component 2, which is arranged on the box body 11 and is used to process sewage; The aeration component 3 is arranged on one side of the box body 11 and is used for aeration during sewage treatment and adjustment of aeration amount.

[0020] When treating sewage, the sewage enters the box 11 through the liquid pipe 12, and the sewage is transported and treated through the treatment component 2 to reduce substances in the sewage that may pollute the environment. Gas can be introduced into the aerobic tank 23 through the aeration component 3, and the aeration amount can be adjusted according to the amount of sewage in the aerobic tank 23 so that the amount of gas introduced is matched with the amount of sewage, and the gas introduction amount is guaranteed to improve the aerobic treatment effect of the sewage. Therefore, the treatment effect of the sewage can be improved through the treatment component 2 and the aeration component 3, and the organic matter in the sewage cannot be completely decomposed due to insufficient oxygen supply or short treatment time, thereby preventing the generation of floating objects such as sludge, which cannot be effectively precipitated and affects the treatment of the sewage.

[0021] The treatment assembly 2 includes three partitions 21 fixedly mounted on the inner side of the housing 11. The inner side of the housing 11 is separated by the partitions 21 into an anaerobic tank 22, an aerobic tank 23, a sedimentation tank 24 and a waste tank 25. Lifting plates 28 are slidably mounted on the inner sides of the anaerobic tank 22, the aerobic tank 23 and the sedimentation tank 24. A sealing member is mounted on the side end of the lifting plate 28. A connecting pipe 26 is fixedly mounted on the three partitions 21. A solenoid valve 27 is mounted on the connecting pipe 26. The connecting pipe 26 is tilted. The upper end surface of the lifting plate 28 is provided with a slope toward the connecting pipe 26, so that the sewage can pass through the connecting pipe 26. Circulation, and the height of the three connecting pipes 26 gradually decreases from the direction close to the liquid pipe 12 to the direction gradually away from it, so as to ensure that when the lifting plate 28 is lifted, the sewage can flow out through the corresponding connecting pipes 26. Three brackets 29 are fixedly arranged on the upper side of the box body 11, and a roller 210 and a first gear 211 are rotatably arranged on the bracket 29. The roller 210 and the first gear 211 are fixedly arranged. A pull rope member 212 is arranged between the lifting plate 28 and the roller 210, and the pull rope member 212 passes through the top of the box body 11. A sealing gasket can be arranged at the place where the pull rope member 212 passes through the box body 11 for sealing.

[0022] A first pressure plate 214 is slidably provided on the upper side of the sedimentation tank 24 of the box body 11, and a first switch 217 is installed on the upper side of the first pressure plate 214 of the box body 11. The first switch 217 is electrically connected to the first motor 221, and a first spring 216 fixed to the box body 11 is symmetrically fixed on the upper side of the first pressure plate 214. When in use, sewage enters the anaerobic tank 22 through the liquid pipe 12. When the sewage is treated, gas is generated during the fermentation of the sewage in the sedimentation tank 24. When the fermentation reaches a certain level, a large amount of gas will accumulate in the sedimentation tank 24, thereby pressing the first pressure plate 214 to move up and press the first switch 217 to control the first motor 221 to work. The elasticity of the second spring 218 is greater than the elasticity of the first spring 216, so that when a large amount of gas accumulates and presses the first switch 217, the second pressure plate 215 above the sedimentation tank 24 will not press the second switch 219.

[0023] A mounting plate 220 is provided on the upper side of the housing 11, and a first motor 221 fixed to the housing 11 is provided on one side of the mounting plate 220, a screw rod 222 rotatably provided to the mounting plate 220 is fixed to the output end of the first motor 221, a slide rod 223 is fixed to the mounting plate 220, a moving block 224 slidably provided to the slide rod 223 is threadedly provided on the screw rod 222, and three mounting blocks 231 fixed to the housing 11 are provided on one side of the mounting plate 220, two third switches 232 are installed on a side of the mounting block 231 close to the mounting plate 220, and an inclined surface is provided on a side of the moving block 224 close to the mounting block 231 to facilitate the pressing of the third switch 232, a third switch 232 on one side of the mounting block 231 is electrically connected to the first motor 221, and another third switch 232 is electrically connected to the second motor 225 and the solenoid valve 27 on the corresponding side.

[0024] When the first pressure plate 214 presses the first switch 217 to control the first motor 221 to work, the output end of the first motor 221 drives the screw rod 222 to rotate, so that the moving block 224 moves along the slide bar 223 close to the mounting block 231. When the moving block 224 moves to the position of the first mounting block 231 close to the first motor 221, the moving block 224 presses the two third switches 232 on one side of the secondary mounting block 231. By pressing one of the third switches 232, the first motor 221 stops working. At this time, the second gear 230 is meshed with the first gear 211 above the sedimentation tank 24. By pressing the other third switch The pressing action of 232 can control the second motor 225 to work, so as to drive the second gear 230 to rotate, and then drive the first gear 211 and the roller 210 above the sedimentation tank 24 to rotate, and pull the lifting plate 28 in the sedimentation tank 24 upward by pulling the rope member 212. At the same time, the pressing action of another third switch 232 can open the solenoid valve 27 on the corresponding side, that is, control the solenoid valve 27 on the connecting pipe 26 on the partition 21 between the sedimentation tank 24 and the waste tank 25 to open, so that when the lifting plate 28 in the sedimentation tank 24 moves upward, the sewage in the sedimentation tank 24 can flow into the waste tank 25 through this connecting pipe 26.

[0025] A second motor 225 is fixedly provided on the upper side of the moving block 224, a connecting rod 226 is fixedly provided at the output end of the second motor 225, a cylinder part 227 is slidably provided on the outer side of the connecting rod 226, and limiting grooves 228 matched with the connecting rod 226 are symmetrically provided on the cylinder part 227, the connecting rod 226 is slidably arranged along the limiting groove 228, a third spring 229 fixed with the cylinder part 227 is fixedly provided on one side of the connecting rod 226, and a second gear 230 is fixedly provided at one end of the cylinder part 227.

[0026] When the moving block 224 moves to the position of the mounting block 231, if the second gear 230 does not correspond to the tooth groove of the first gear 211, the second gear 230 will drive the cylinder part 227 to move closer to the second motor 225 under the obstruction of the first gear 211. Relatively speaking, the connecting rod 226 slides toward the inner side of the cylinder part 227, and the third spring 229 is compressed. When the second motor 225 works, the connecting rod 226 is driven to rotate, and through the limiting groove 228, the cylinder part 227 and the second gear 230 are driven to rotate. When the second gear 230 rotates to correspond to the tooth groove of the first gear 211, under the elastic force of the third spring 229, the second gear 230 is stuck in the tooth groove of the first gear 211, thereby driving the rotation of the first gear 211.

[0027] The box body 11 is located on the upper side of the anaerobic tank 22, the aerobic tank 23 and the sedimentation tank 24, and a second pressure plate 215 is slidably provided. The box body 11 is located on the upper side of the second pressure plate 215 and is equipped with two second switches 219. The second pressure plate 215 is symmetrically fixed with a second spring 218 fixed to the box body 11 on the upper side. The three lifting plates 28 are all fixed with a pressure rod 213 on the upper side. The three pressure rods 213 correspond to the three second pressure plates 215 up and down respectively. A fifth switch 236 is installed on one side of the mounting plate 220, which is close to the liquid passage. As the heights of the three connecting pipes 26 from the direction of the pipe 12 to the direction gradually away from the pipe 12 gradually decrease, the heights of the lifting plates 28 in the anaerobic tank 22, the aerobic tank 23 and the sedimentation tank 24 gradually decrease to prevent the lifting plates 28 from moving up to the upper side of the connecting pipe 26 and obstructing the flow of sewage, the lengths of the pressure rods 213 in the anaerobic tank 22, the aerobic tank 23 and the sedimentation tank 24 are increased successively to ensure that when the lifting plates 28 move up to the lower side of the connecting pipe 26, the pressure rods 213 can press against the corresponding second pressure plates 215.

[0028] A telescopic end of an electric push rod 240 is fixedly provided on one side of the mounting plate 220, and the electric push rod 240 is fixedly provided on the box body 11. A guide piece 233 is symmetrically fixedly provided on one side of the mounting plate 220, and two limit blocks 234 fixedly provided on one side of the two guide pieces 233 are respectively provided with two limit blocks 234 fixedly provided on the box body 11. The guide piece 233 passes through the limit blocks 234 close to one side of the mounting plate 220, and a fourth switch 235 is installed on the side where the two limit blocks 234 are close to each other. A first delivery pump 238 is fixedly provided on the upper side of the box body 11, and one end of the first delivery pump 238 is fixedly connected to a delivery pipe 239 connected to the waste tank 25, and the other end of the first delivery pump 238 is fixedly connected to the waste tank 25. An output pipe 237 is connected; a protective shell 41 is fixedly provided on the top of the box body 11, and the output pipe 237 passes through one side of the protective shell 41. Through holes are symmetrically opened on both sides of the protective shell 41, and a filter screen 43 is fixedly provided at the through hole of the protective shell 41 for ventilation and heat dissipation. A solar panel 42 is installed on the upper side of the protective shell 41, and a battery 44 is fixedly provided on the upper side of the box body 11. The battery 44 is electrically connected to the solar panel 42 and related power devices, and the solar energy is converted into electrical energy in the battery 44 through the solar panel 42 to provide power supply for the equipment. When used in remote areas, no municipal power supply is required, which is equivalent to saving municipal power.

[0029] When the lifting plate 28 in the sedimentation tank 24 is pulled up to the lower end of the pipe opening of the connecting pipe 26 away from the side of the liquid passing pipe 12, the pressure rod 213 in the sedimentation tank 24 can press the second pressure plate 215 above the sedimentation tank 24 to move up and press the two second switches 219. By pressing one of the second switches 219, the second motor 225 can be controlled to stop working to prevent the lifting plate 28 in the sedimentation tank 24 from continuing to move up. By pressing the other second switch 219, the first motor 225 can be controlled to stop working after a certain period of time. 1 works, and the electromagnetic valve 27 between the sedimentation tank 24 and the waste tank 25 is closed. During this time, the height position of the lifting plate 28 in the sedimentation tank 24 can be maintained, so that the sewage in the sedimentation tank 24 can be passed into the waste tank 25 through the connecting pipe 26 away from the side of the liquid pipe 12. The first motor 221 works to drive the moving block 224 to continue to move close to the mounting block 231 on the middle side, so that the second gear 230 is separated from the first gear 211 above the sedimentation tank 24. Under the action of the deadweight of the lifting plate 28, the lifting plate 28 moves down and resets; Similarly, when the moving block 224 moves to the position of the middle side mounting block 231, the second gear 230 is meshed with the first gear 211 on the upper side of the aerobic tank 23, which can drive the lifting plate 28 in the aerobic tank 23 to move upward, so that the sewage in the aerobic tank 23 passes into the sedimentation tank 24 through the connecting pipe 26 on the middle side partition plate 21, and the pressure rod 213 in the aerobic tank 23 presses the second pressure plate 215 above the aerobic tank 23 to move upward and press the two second switches 219. Similarly, after a certain period of time, through the first gear 211, the sewage in the aerobic tank 23 is discharged into the sedimentation tank 24. The driving of the motor 221 can make the moving block 224 move close to the third mounting block 231. Similarly, the sewage in the anaerobic tank 22 can be passed into the aerobic tank 23 through the connecting pipe 26 close to the side of the liquid pipe 12. The pressure rod 213 in the anaerobic tank 22 presses the second pressure plate 215 above the anaerobic tank 22 to move upward, and the pressing effect on the second switch 219 above the anaerobic tank 22 can cause the electric push rod 240 to drive the mounting plate 220 to move away from the bracket 29 after a certain period of time, and the mounting plate 220 moves downward. A roller can be provided on the side to facilitate the movement on the upper side of the box body 11, so that the second gear 230 is separated from the first gear 211 above the anaerobic tank 22. When the guide member 233 presses against the fourth switch 235 on the limit block 234 away from the side of the mounting plate 220, the electric push rod 240 stops working, and controls the first motor 221 to drive the screw rod 222 to reverse, so that the moving block 224 moves in the opposite direction and resets. When the moving block 224 presses against the fifth switch 236, the first motor 221 stops working, and controls the electric push rod 2 40 drives the mounting plate 220 to move close to the bracket 29. When the guide member 233 presses against the fourth switch 235 on the limit block 234 close to one side of the mounting plate 220, the electric push rod 240 stops working. At this time, the processing component 2 completes the reset. At the same time, the first delivery pump 238 can be controlled to work, and the sewage in the waste pool 25 is pumped out through the delivery pipe 239.

A tooth rod 315 fixed to the connecting plate 312 and the shell 36 is arranged on one side of the beveled tooth block 317. The tooth rod 315 cooperates with the beveled tooth block 317. A first electromagnetic block 313 is fixed on one side of the connecting plate 312. A magnet block 319 repelling the first electromagnetic block 313 is fixed on one side of the connecting member 39. The first electromagnetic block 313 is electrically connected to the power generation device 37.

[0032] When the lifting plate 28 in the anaerobic tank 22 moves upward, so that the sewage in the anaerobic tank 22 is passed into the aerobic tank 23 through the connecting pipe 26 close to the side of the liquid pipe 12, the flow of sewage can drive the rotation of the impeller 33, so that the shaft 34 rotates, and the first electromagnetic block 313 is energized through the power generation device 37 to generate a repulsive effect on the magnet block 319, so that the connecting piece 39 moves away from the connecting plate 312, and the fourth spring 311 is compressed. When a large amount of sewage is passed in, the repulsive effect of the first electromagnetic block 313 on the magnet block 319 is large, so that the connecting piece 39 moves a large distance, so that the resistance value of the sliding rheostat 38 connected to the circuit is reduced more, so that the power of the blower 31 is relatively large, so that when aeration is introduced into the aerobic tank 23 through the blower 31, more gas can be introduced into the aerobic tank 23 to improve the aerobic treatment effect of the sewage; When the connecting member 39 moves away from the connecting plate 312, the bevel gear block 317 moves along the gear rod 315 and limits the reverse movement of the bevel gear block 317 close to the connecting plate 312, so that the position of the slider of the sliding rheostat 38 after adjustment can be maintained to ensure the adjustment of the blower 31. When the guide member 233 presses against the fourth switch 235 on the limit block 234 on the side close to the mounting plate 220 to complete the reset of the processing component 2, the second electromagnetic block 316 can be energized to produce an adsorption effect on the bevel gear block 317, so that the bevel gear block 317 is separated from the gear rod 315. Under the elastic force of the fourth spring 311, the connecting member 39 drives the slider of the sliding rheostat 38 to move in the opposite direction and reset. Embodiment 2
