Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a digital intelligent system for hierarchical treatment of rural domestic sewage. Background Art

[0002] With the development of rural economy and the enhancement of environmental protection awareness, sewage treatment facilities have been established and improved everywhere to solve the problems of rural domestic sewage and agricultural wastewater discharge. In recent years, many places have begun to adopt new sewage treatment technologies such as ecological treatment and plant wetlands, which have improved the efficiency and sustainability of sewage treatment. Rural sewage treatment systems can not only effectively remove harmful substances, but also recycle water resources for circular utilization. With the continuous progress of technology, the operation efficiency has been further improved, promoting the improvement of the rural environment and ecological balance.

[0003] When treating rural sewage, general sewage treatment systems usually can only achieve solid-liquid separation, and cannot further dehydrate solid impurities, resulting in a large amount of fermentation space occupied by the treated solid residues, affecting the subsequent treatment effect. The accumulation of solid impurities also makes the fermentation equipment need to be cleaned frequently in a short time, increasing the maintenance cost and manual workload. Due to the insufficient dehydration treatment of solid impurities, the air circulation during the fermentation process may be blocked, thus affecting the fermentation efficiency and reducing the overall effect of sewage treatment, which cannot meet the actual needs.

The multi-way pipes can be set with different diameters for collecting different types of sewage.

[0011] In a preferred embodiment, the buoyancy mechanism includes a separation box fixedly connected to the inner wall of one side of the sewage tank.

[0014] A ventilation pipe is inserted into the top of the sedimentation tank. A ventilation valve is provided at one end of the ventilation pipe. A drain pipe is provided at the bottom of the sedimentation tank. A drain valve is provided at the bottom end of the drain pipe.

[0015] As can be seen from the above, a digital intelligent system for hierarchical treatment of rural domestic sewage provided by the present invention has the following technical effects.

[0016] First: By using the piston and the filter plate to squeeze the solid impurities flowing into the pressure-bearing cylinder, the sewage liquid inside the solid impurities is filtered and separated through the filter plate. The piston and the pressure-bearing plate cooperate to squeeze the solid impurities, further pressing and dewatering the solid impurities in the sewage, reducing the volume of the solid impurities, reducing the occupied space, increasing the utilization efficiency of the internal space of the fermentation tank, extending the cleaning cycle of the fermentation tank, and achieving the effect of further pressing and dewatering the solid impurities in rural sewage.

[0017] Second: When the first sliding column inside the one-way shell connected to the return pipe slides downward, the return pipe is connected to the inside of the pressure-bearing cylinder, sucking the sewage liquid inside the separation box into the inside of the pressure-bearing cylinder. When the piston slides to the right, the internal spaces of the first sealing cylinder and the second sealing cylinder decrease, squeezing the sewage liquid inside the first sealing cylinder and the second sealing cylinder. Similarly, it is discharged into the drain pipe through the second one-way shell. The one-way shell, the first sliding column, the second connection hole, and the second sliding column are all designed as one-way valves, only allowing liquid to pass unidirectionally.

[0018] Thirdly: When only the liquid part remains of the sewage above the interior of the sewage tank, the buoyancy blocks below the sewage liquid level inside the sewage tank are all subject to the buoyancy force. Due to the buoyancy force of the buoyancy blocks, the starting main column is driven to slide upward, enabling the interior of the starting shell and the separation tank to be connected. As a result, the sewage inside the sewage tank enters the interior of the separation tank through the liquid inlet plate, the starting shell, and the connecting pipe. Since some solid-liquid mixed impurities enter the interior of the separation tank through the holes, it also achieves the effect of solid-liquid separation of the sewage inside the sewage tank.

[0019] Fourthly: Through the design of the liquid separation plate and the liquid leakage holes, the solid-liquid mixed sewage precipitates on the upper surface of the liquid separation plate, and the liquid enters the lower part through the liquid leakage holes, preventing the solid-liquid mixed sewage from concentrating and precipitating at the bottom of the separation tank and preventing the bottom precipitation from blocking the return pipe.

The filter plate 58 is a hard fiber filter membrane. An intelligent controller is arranged on the top of the sewage tank 1.

[0033] The recycling mechanism includes a return pipe 52 provided at the bottom of the sewage tank 1. Two one-way housings 50 are provided on the upper surface of the pressure-bearing cylinder 48 near the return pipe 52. A first sliding column 51 is slidably connected inside the one-way housing 50. A first spring is provided at the bottom end of the first sliding column 51. A plurality of first connection holes 49 are provided around the first sliding column 51 inside the one-way housing 50. A plurality of second sliding columns 57 are slidably connected inside the piston 59. A second spring is sleeved at one end of the second sliding column 57.

A connection port 60 is provided on the upper surface of one end of the second sealing cylinder 55.

[0034] One side of the treatment tank 2 is fixedly connected with a sedimentation tank 4. A drain pipe 53 is inserted into the top of the sedimentation tank 4. There are two one-way housings 50. One one-way housing 50 is connected to the return pipe 52, and the other one-way housing 50 is connected to the drain pipe 53. The installation positions of the first sliding columns 51 inside the two one-way housings 50 are opposite. The return pipe 52 penetrates through the bottom of the sewage tank 1 and the top of the treatment tank 2. A pressure-bearing disc 46 is slidably connected to the side of the piston 59 inside the pressure-bearing cylinder 48. An auxiliary rod 45 is fixedly connected to one side of the pressure-bearing disc 46. A fixing ring 41 is provided at the middle position of the outer surface of the auxiliary rod 45. A sliding rod is fixedly connected to one side of the fixing ring 41. The bottom of the material receiving cylinder 40 is fixedly connected with a fermentation tank 3. One side of the material receiving cylinder 40 is fixedly connected with a mounting frame. The top of the mounting frame is fixedly connected with a groove plate 42. A chute is provided on one side of the groove plate 42. A plug rod 43 is slidably connected through one side of the mounting frame. An auxiliary spring 44 is sleeved at one end of the plug rod 43. The sliding rod slides inside the chute. One end of the plug rod 43 is rotatably connected to one end of the auxiliary rod 45.

[0035] In this embodiment, the sewage inside the sewage tank 1 undergoes sedimentation, and the solid impurities sink to the bottom. The upper part is the liquid part of the sewage. Since the solid impurities contain moisture and have a certain fluidity effect, they flow through the feed port on the upper surface of the pressure-bearing cylinder 48 through the feed port at the bottom of the sewage tank 1. The discharge device 32 is driven to rotate by the main shaft 14, and the fluid solid impurities are discharged into the inside of the pressure-bearing cylinder 48. The continuous rotation of the main shaft 14 drives the first rack 34 to slide towards one side of the pressure-bearing disc 46 through the incomplete gear 33, thereby driving the main rod 36 and the piston 59 to slide towards the pressure-bearing disc 46. The solid impurities flowing into the pressure-bearing cylinder 48 are squeezed by the piston 59 and the filter plate 58, and the sewage liquid inside the solid impurities is filtered and separated through the filter plate 58. The piston 59 and the pressure-bearing disc 46 cooperate to squeeze the solid impurities.

[0036] Furthermore, as the pressure continues to increase, the pressure plate 46 and the piston 59 slide to one side together, the auxiliary rod 45 drives the insertion rod 43 to compress the auxiliary spring 44, and the slide rod slides inside the slide groove, so that the pressure plate 46 reaches the position of the discharge port at one end of the pressure cylinder 48. The design of the slide groove on the groove plate 42 causes the auxiliary rod 45 to rotate, and the solid impurities squeezed into a cake shape between the pressure plate 46 and the buoyancy block 29 are transmitted to the inside of the receiving cylinder 40. Due to the design of the incomplete gear 33, the toothless part of the incomplete gear 33 When disengaged from the first rack 34, the main rod 36 slides to the right under the elastic force of the main spring 35, so that the main rod 36 and the piston 59 return to their original positions. Similarly, the insertion rod 43 and the auxiliary rod 45 also return to their original positions under the elastic force of the auxiliary spring 44, so that the solid impurities in the sewage are further filtered and dehydrated, the volume of the solid impurities is reduced, the occupied space is reduced, the utilization efficiency of the internal space of the fermentation tank 3 is increased, and the cycle of cleaning the fermentation tank 3 is extended, so as to further filter and dehydrate the solid impurities in the rural sewage.

[0037] In this embodiment, during the sliding back and forth of the sliding plate 47, the second rack 38 is also driven to slide back and forth, thereby driving the sealing gear 39 and the rotating cover 37 to rotate back and forth. When the cake-shaped solid impurities enter the interior of the receiving barrel 40, the fermentation port on the rotating cover 37 is at the bottom of the receiving barrel 40, so that the cake-shaped solid impurities just fall into the interior of the fermentation tank 3. When the second rack 38 returns to its original position, the fermentation port on the rotating cover 37 is staggered from the bottom of the receiving barrel 40, thereby achieving the effect of closing the fermentation tank 3. The solid impurities in the rural sewage are fermented inside the fermentation tank 3 to produce biogas for rural households, thereby recycling energy.

[0038] What needs to be explained further is that when the piston 59 moves back and forth, the piston 59 drives the first sealing cylinder 54 to slide, and the first sealing cylinder 54 drives the second sealing cylinder 55 to slide, thereby isolating the interior of the pressure cylinder 48 and preventing solid impurities from entering the interior of the pressure cylinder 48 through the feed port above the pressure cylinder 48. The connection port 60 is designed to keep the interiors of the pressure cylinder 48, the first sealing cylinder 54 and the second sealing cylinder 55 connected to the one-way shell 50. When the piston 59 slides to one side of the pressure plate 46, the moisture inside the solid impurities squeezes the second sliding column 57 through the filter plate 58 and enters the interior of the first sealing cylinder 54 and the second sealing cylinder 55 through the second connecting hole 56. As the piston 59 slides to one side, the internal space of the first sealing cylinder 54 and the second sealing cylinder 55 increases, generating negative pressure.

[0039] Further, the first sliding column 51 inside the one-way housing 50 connected to the return pipe 52 slides downward, enabling the return pipe 52 to communicate with the inside of the pressure-bearing cylinder 48, sucking the sewage liquid inside the separation tank 8 into the inside of the pressure-bearing cylinder 48. When the piston 59 slides to the right, the internal spaces of the first sealing cylinder 54 and the second sealing cylinder 55 decrease, squeezing the sewage liquid inside the first sealing cylinder 54 and the second sealing cylinder 55. Similarly, it is discharged into the drain pipe 53 through the second one-way housing 50. The one-way housing 50, the first sliding column 51, the second connection hole 56, and the second sliding column 57 are all designed as one-way valves, only allowing liquid to pass through unidirectionally.

[0040] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in a preferred embodiment, the collection mechanism includes an impeller 25 fixedly connected to the top end of the main shaft 14. A plurality of communication ports 16 are respectively arranged at the inner edge position of the suction box 7. A plurality of fixing pieces 15 are fixedly connected to the upper edge of the inner wall of the suction box 7 at the bottom position of the communication ports 16. Two rotating pieces 17 are fixedly connected to one end of the main shaft 14 at the bottom position of the impeller 25. A plurality of auxiliary pipes 24 are respectively arranged around the motor 18 at the top of the suction box 7. A treatment pipe 22 is arranged on one side of the auxiliary pipe 24. A flushing valve 23 is arranged at one end of the treatment pipe 22. An electromagnetic valve 21 is arranged at the top of the auxiliary pipe 24. A multi-way connector 19 is arranged on the upper surface of the electromagnetic valve 21. A plurality of multi-way pipes 20 are arranged on the outer wall of the multi-way connector 19. A plurality of communication holes are arranged at the bottom of the suction box 7.

[0041] The fixing pieces 15 and the rotating pieces 17 are at the same height, and the position of the rotating pieces 17 is slightly higher than that of the fixing pieces 15 and above the fixing pieces 15. During the rotation of the rotating pieces 17, the rotating pieces 17 and the fixing pieces 15 cooperate with each other to cut off the fibrous and flocculent impurities in the sewage. The multi-way pipes 20 can be set with different diameters to collect different types of sewage.

[0042] In this embodiment, when there is no place to discharge rural sewage, by connecting the sewage pipe to the multi-way pipe 20, due to the design of the multi-way connector 19 and the plurality of multi-way pipes 20, the sewage treatment needs of multiple families can be satisfied simultaneously. When the motor 18 is started to drive the impeller 25 to rotate, due to the centrifugal force, the air inside the suction box 7 is thrown to the surroundings, and the air is discharged into the sewage cylinder 1 through the communication ports 16 and the communication holes at the bottom of the suction box 7, generating negative pressure inside the suction box 7.

[0043] Further, the solenoid valve 21 is opened to suck sewage into the suction box 7 through the multi-way connector 19 and the multi-way pipe 20. Similarly, the sewage is discharged into the interior of the sewage cylinder 1 through the communication port 16 and the communication hole. The sewage contains fibrous or flocculent impurities. The rotating blade 17 is driven to rotate by the main shaft 14. The rotating blade 17 and the fixed blade 15 cooperate to crush the fibrous or flocculent impurities to prevent the impurities from blocking the communication hole at the bottom of the suction box 7. When the solid impurities in the sewage block the auxiliary pipe 24, a water pipe with a certain water pressure is connected to one end of the flushing valve 23, and water with a certain pressure is poured into the interior to dredge the blocked position, achieving the effect of dredging the blockage.

[0044] What needs to be further explained is that the flushing valve 23 and the solenoid valve 21 are connected to the intelligent controller, and the intelligent controller controls the on and off of the flushing valve 23 and the solenoid valve 21 without manual operation. The intelligent controller and the flushing valve 23 can be common existing products on the market.

[0045] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in a preferred embodiment, the buoyancy mechanism includes a separation box 8 fixedly connected to the inner wall of one side of the sewage cylinder 1. Two liquid separation plates 27 are fixedly connected to the inner wall of the separation box 8. A plurality of liquid leakage holes 28 are arranged on the upper surface of the liquid separation plate 27. A plurality of connecting pipes are respectively inserted into one side of the separation box 8. One ends of the connecting pipes are respectively fixedly connected to starting shells 31. A liquid inlet tray 26 is fixedly connected to the top of the starting shell 31. A starting main column 30 is slidably connected to the interior of the starting shell 31. A buoyancy block 29 is fixedly connected to the bottom end of the starting main column 30.

[0046] The liquid inlet tray 26 is communicated with the interior of the starting shell 31. The interior of the connecting pipe frame separation box 8 is communicated with the interior of the starting shell 31. A protrusion is arranged at the central position on the surface of the starting main column 30, and this protrusion isolates the upper and lower spaces inside the starting shell 31. When the starting main column 30 slides upward, the upper and lower spaces inside the starting shell 31 can be communicated.

[0047] In this embodiment, only the liquid part of the sewage remains above the interior of the sewage tank 1. The buoyancy blocks 29 below the sewage liquid level inside the sewage tank 1 are all subject to the buoyancy force. Due to the buoyancy force of the buoyancy blocks 29, the starting main column 30 is driven to slide upward, enabling the interior of the starting housing 31 and the separation tank 8 to be connected. As a result, the sewage inside the sewage tank 1 passes through the liquid inlet tray 26, the starting housing 31, and the connecting pipe and enters the interior of the separation tank 8. Since some solid-liquid mixed impurities enter the interior of the separation tank 8 through the holes, through the design of the liquid separation plate 27 and the liquid leakage holes 28, the solid-liquid mixed sewage precipitates on the upper surface of the liquid separation plate 27, and the liquid passes through the liquid leakage holes 28 to the lower part, preventing the solid-liquid mixed sewage from concentrating and precipitating at the bottom of the separation tank 8 and preventing the bottom precipitation from blocking the return pipe 52. It also achieves the effect of solid-liquid separation of the sewage inside the sewage tank 1.

[0048] Referring to Figure 1 and Figure 2 , in a preferred embodiment, the gravity filtration mechanism includes a plurality of partition plates disposed inside the sedimentation tank 4. Gravel 9 is disposed below the first partition plate, a fiber layer 10 is disposed below the second partition plate, and activated carbon 11 is disposed below the third partition plate.

[0049] A ventilation pipe 5 is inserted into the top of the sedimentation tank 4. One end of the ventilation pipe 5 is provided with a ventilation valve 6. A drain pipe 12 is disposed at the bottom of the sedimentation tank 4, and a drain valve 13 is disposed at the bottom end of the drain pipe 12.

[0050] In this embodiment, when the sewage liquid enters the interior of the sedimentation tank 4 through the drain pipe 53, the sewage is naturally settled by gravity. The impurities inside the sewage are further removed through the filtration of the gravel 9, the fiber layer 10, and the activated carbon 11. The drain valve 13 is opened to discharge the filtered sewage into the ground through the drain pipe 12, achieving the effects of treating the impurities in the sewage and protecting the environment. The ventilation pipe 5 and the ventilation valve 6 can be used to connect air to accelerate the sedimentation of the sewage in the sedimentation tank 4.

[0051] Furthermore, when the filtration effects of the gravel 9, the fiber layer 10, and the activated carbon 11 decline and the interior of the sedimentation tank 4 needs to be cleaned, the ventilation valve 6 is controlled by the intelligent controller to close to prevent sewage from flowing out through the ventilation pipe 5.

[0052] Working principle: When in use, when there is no place to discharge rural sewage, the sewage pipeline is connected to the multi-way pipe 20. Due to the design of the multi-way connector 19 and multiple multi-way pipes 20, the sewage treatment needs of multiple families can be satisfied simultaneously. When the motor 18 is started to drive the impeller 25 to rotate, due to the action of centrifugal force, the air inside the suction box 7 is thrown to the surroundings, and the air is discharged into the interior of the sewage cylinder 1 through the communication port 16 and the communication hole at the bottom of the suction box 7, generating negative pressure inside the suction box 7. The solenoid valve 21 is opened to suck sewage into the interior of the suction box 7 through the multi-way connector 19 and the multi-way pipe 20. Similarly, the sewage is discharged into the interior of the sewage cylinder 1 through the communication port 16 and the communication hole. The sewage contains fibrous or flocculent impurities. The rotating blade 17 is driven to rotate by the main shaft 14, and the rotating blade 17 and the fixed blade 15 cooperate to crush the fibrous or flocculent impurities to prevent the impurities from blocking the communication hole at the bottom of the suction box 7. When the solid impurities in the sewage block the auxiliary pipe 24, a water pipe with a certain water pressure is connected to one end of the flushing valve 23, and water with a certain pressure is poured into it to dredge the blocked position, achieving the effect of dredging the blockage. The sewage in the sewage cylinder 1 undergoes sedimentation, and the solid impurities sink to the bottom. The upper part is the liquid part of the sewage. Since the solid impurities contain moisture and have a certain fluidity effect, they flow through the feeding port on the upper surface of the pressure-bearing cylinder 48 through the feeding port at the bottom of the sewage cylinder 1. The discharging device 32 is driven to rotate by the main shaft 14 to discharge the fluid solid impurities into the interior of the pressure-bearing cylinder 48. The main shaft 14 continuously rotates to drive the first rack 34 to slide towards one side of the pressure-bearing plate 46 through the incomplete gear 33, thereby driving the main rod 36 and the piston 59 to slide towards the pressure-bearing plate 46. The solid impurities flowing into the interior of the pressure-bearing cylinder 48 are squeezed by the piston 59 and the filter plate 58, and the sewage liquid inside the solid impurities is filtered and separated through the filter plate 58. The piston 59 and the pressure-bearing plate 46 cooperate to squeeze the solid impurities. When the pressure continuously increases, the pressure-bearing plate 46 and the piston 59 slide towards one side together, and the auxiliary rod 45 drives the plug rod 43 to compress the auxiliary spring 44. The sliding rod slides inside the sliding groove, so that the pressure-bearing plate 46 reaches the position of the discharging port at one end of the pressure-bearing cylinder 48. Due to the design of the sliding groove on the groove plate 42, the auxiliary rod 45 rotates, and the solid impurities squeezed into a cake shape between the pressure-bearing plate 46 and the buoyancy block 29 are conveyed into the interior of the receiving cylinder 40. Due to the design of the incomplete gear 33, when the toothless part of the incomplete gear 33 disengages from the first rack 34, the main rod 36 slides to the right under the elastic force of the main spring 35, so that the main rod 36 and the piston 59 return to their original positions. Similarly, the plug rod 43 and the auxiliary rod 45 also return to their original positions under the elastic force of the auxiliary spring 44, further pressing and dewatering the solid impurities in the sewage, reducing the volume of the solid impurities, reducing the occupied space, increasing the utilization efficiency of the space inside the fermentation tank 3, and extending the cleaning cycle of the fermentation tank 3, achieving the effect of further pressing and dewatering the solid impurities in rural sewage. During the process of the sliding plate 47 sliding back and forth, it also drives the second rack 38 to slide back and forth, thereby driving the sealing gear 39 and the rotating cover 37 to rotate back and forth.When the cake-shaped solid impurities enter the receiving barrel 40, the fermentation port on the rotating cover 37 is at the bottom of the receiving barrel 40, so that the cake-shaped solid impurities just fall into the fermentation tank 3. When the second rack 38 returns to its original position, the fermentation port on the rotating cover 37 is staggered with the bottom of the receiving barrel 40, thereby achieving the effect of closing the fermentation tank 3. The solid impurities in the rural sewage are fermented inside the fermentation tank 3 to produce biogas for rural households, thereby recycling energy. Only the liquid part of the sewage above the sewage barrel 1 remains, and the buoyancy blocks 29 below the sewage liquid surface inside the sewage barrel 1 are all affected by buoyancy. Due to the buoyancy of the buoyancy blocks 29, the starting main column 30 is driven to slide upward, so that the starting shell 31 is connected with the inside of the separation box 8, so that the sewage barrel 1 is connected. 1 The internal sewage enters the separation box 8 through the liquid inlet plate 26, the starter shell 31 and the connecting pipe. Since some solid-liquid mixed impurities in the hole enter the separation box 8, the solid-liquid mixed sewage is precipitated on the upper surface of the liquid partition plate 27 through the design of the liquid partition plate 27 and the leakage hole 28, and the liquid enters the bottom through the leakage hole 28, so as to prevent the solid-liquid mixed sewage from being concentrated and precipitated at the bottom of the separation box 8, and to prevent the bottom precipitation from clogging the return pipe 52, and also play the effect of solid-liquid separation of the sewage inside the sewage cylinder 1. When the piston 59 moves back and forth, the piston 59 drives the first sealing cylinder 54 to slide, and the first sealing cylinder 54 drives the second sealing cylinder 55 to slide, so as to isolate the interior of the pressure cylinder 48, and prevent the solid impurities from entering the pressure cylinder 48 through the feed port above the pressure cylinder 48. The connection port 60 is designed to keep the interior of the pressure cylinder 48, the first sealing cylinder 54 and the second sealing cylinder 55 connected to the one-way shell 50. When the piston 59 slides to one side of the pressure plate 46, the moisture inside the solid impurities squeezes the second sliding column 57 through the filter plate 58 and enters the interior of the first sealing cylinder 54 and the second sealing cylinder 55 through the second connecting hole 56. As the piston 59 slides to one side, the internal space of the first sealing cylinder 54 and the second sealing cylinder 55 increases and generates negative pressure. The first sliding column 51 inside the one-way shell 50 connected to the return pipe 52 slides downward, so that the return pipe 52 is connected to the interior of the pressure cylinder 48, and the sewage liquid inside the separation box 8 is sucked into the interior of the pressure cylinder 48. When the piston 59 slides to the right, the first The internal space of the first sealing cylinder 54 and the second sealing cylinder 55 is reduced, and the internal sewage liquid of the first sealing cylinder 54 and the second sealing cylinder 55 is squeezed, and similarly discharged into the drainage pipe 53 through the second one-way shell 50. The one-way shell 50 and the first sliding column 51 and the second connecting hole 56 and the second sliding column 57 are all designed as a one-way valve, which only allows liquid to pass in one direction. When the sewage liquid enters the sedimentation tank 4 through the drainage pipe 53, the sewage is naturally settled by gravity, and the impurities in the sewage are further removed by filtering through the stone 9 fiber layer 10 and the activated carbon 11, and the drainage valve 13 is opened to allow the filtered sewage to be discharged into the ground through the drainage pipe 12, which has the effect of treating impurities in the sewage and protecting the environment. The ventilation pipe 5 and the ventilation valve 6 can be used to connect the air.Accelerate the sedimentation of the sewage in the sedimentation tank 4.,

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
