[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a low-carbon resource-based treatment device for domestic sewage in highway service areas, such as... Figures 1-8 As shown, the low-carbon resource utilization treatment equipment for domestic sewage in highway service areas includes: a tank 1, multiple treatment chambers, an ecological pool 8, a conveying mechanism, and a filtration mechanism; the multiple treatment chambers are spaced apart inside the tank 1; the ecological pool 8 is connected to the tank 1; the conveying mechanism and the filtration mechanism are respectively installed in the tank 1 and the treatment chamber; the filtration mechanism is used to treat domestic sewage in highway service areas; and the conveying mechanism is used to transport precipitated impurities.

[0020] In this embodiment, when using the low-carbon resource utilization treatment equipment for domestic sewage in highway service areas, the domestic sewage generated in the highway service area is first introduced into multiple treatment chambers in tank 1. The sewage is filtered by a filtration mechanism to remove impurities and oil from the sewage. At the same time, the impurities that settle during the treatment process are transported by a conveying mechanism to avoid the accumulation of impurities in the treatment chamber and to ensure that the treatment process proceeds in an orderly manner. During the treatment process, multiple treatment chambers are set up in tank 1 to perform graded treatment of sewage, thereby improving the targeting and efficiency of sewage treatment. The filtration mechanism and the conveying mechanism are respectively installed in tank 1 and the treatment chamber, so that the two work together to reduce the space occupied by the equipment, reduce the energy consumption during the operation of the equipment, and reduce the impact of impurity accumulation on the treatment effect. The treated wastewater can be fed into the ecological pool 8 connected to the tank 1 for further purification. The conveying mechanism will collect and transport the precipitated impurities, which will facilitate subsequent resource-based disposal of the impurities. The combination of the effective treatment of wastewater by the filtration mechanism and the timely transport of impurities by the conveying mechanism improves the low-carbon nature and resource utilization rate of the equipment, meeting the treatment needs of domestic sewage in highway service areas.

[0021] In a further preferred embodiment of the present invention, the plurality of treatment chambers include: a first treatment chamber 2, a second treatment chamber 3, and a third treatment chamber 4 for treating oily wastewater; and a fourth treatment chamber 5, a fifth treatment chamber 6, and a sixth treatment chamber 7 for treating public toilet wastewater and wastewater after oil removal treatment; the top of the first treatment chamber 2 is provided with a removable first cover plate 15, and a first water inlet pipe 16 is connected to the first cover plate 15 for connecting to the wastewater pipe of the highway service area kitchen; a filter partition 10 is provided between the first treatment chamber 2 and the second treatment chamber 3; the second treatment chamber 3 and the third treatment chamber 4 are connected to the third treatment chamber 5. A three-way filter pipe 11 is provided between the third treatment chamber 4; a first conduit 12 is provided between the third treatment chamber 4 and the fourth treatment chamber 5, with the outlet end of the first conduit 12 extending into the fourth treatment chamber 5; a baffle plate 13 is fixed in the third treatment chamber 4; a second conduit 19 is provided between the fourth treatment chamber 5 and the fifth treatment chamber 6; a third conduit 20 is provided between the fifth treatment chamber 6 and the sixth treatment chamber 7; a fourth conduit 21 is provided between the sixth treatment chamber 7 and the ecological pond 8, with the outlet end of the fourth conduit 21 extending into the ecological pond 8.

[0022] In this embodiment, when using the device, the oily wastewater from the highway service area kitchen is first introduced into the first treatment chamber 2 through the first water inlet pipe 16 on the first cover plate 15. The wastewater is initially filtered by the filter baffle 10 between the first treatment chamber 2 and the second treatment chamber 3. Then, it is further filtered by the three-way filter pipe 11 between the second treatment chamber 3 and the third treatment chamber 4. At the same time, the baffle plate 13 in the third treatment chamber 4 slows down the flow rate of the wastewater, which facilitates the sedimentation of oil and impurities. Simultaneously, the sedimented impurities are transported by the conveying mechanism. After being treated by oil removal in the first treatment chamber 2, the second treatment chamber 3, and the third treatment chamber 4, the wastewater flows into the fourth treatment chamber 5 through the first conduit 12. Together with the wastewater from the public toilet, it flows sequentially between the fourth treatment chamber 5, the fifth treatment chamber 6, and the sixth treatment chamber 7 through the second conduit 19 and the third conduit 20 for graded treatment. The treatment chambers work together to improve the targeting of wastewater treatment. The filtration mechanism and the conveying mechanism operate synchronously to reduce the energy consumption of the equipment. Finally, the treated wastewater in the sixth treatment chamber 7 flows into the ecological pond 8 through the fourth conduit 21 for further purification. The first cover plate 15 is removable, which facilitates the inspection and maintenance of the first treatment chamber 2. The treatment chambers are connected in an orderly manner through conduits, which makes the wastewater flow smoothly, reduces blockage, improves the stability of equipment operation, and realizes the classified and graded treatment of oily wastewater and public toilet wastewater, thereby enhancing the potential for resource utilization.

[0023] In a further preferred embodiment of the present invention, the filtration mechanism includes: a filter basket 9 disposed in the first processing chamber 2, wherein a scraping mechanism is provided in the filter basket 9; a collection box 28 fixed to one side of the tank body 1, wherein a detachable collection basket 30 is provided in the collection box 28 for collecting waste residue; and a slag discharge pipe 29 fixedly connected to one side of the filter basket 9, wherein the slag discharge end of the slag discharge pipe 29 extends into the collection box 28.

[0024] In this embodiment, when using the filtration mechanism of the device, the oily wastewater from the kitchen is introduced into the first treatment chamber 2 through the first inlet pipe 16 and flows into the filter basket 9. The filter basket 9 intercepts and filters the solid waste in the wastewater to prevent the waste from entering the subsequent treatment process and affecting the treatment effect. At the same time, the scraping mechanism in the filter basket 9 is activated to scrape off the waste attached to the inner wall of the filter basket 9 to prevent the waste from clogging the filter basket 9. The scraped waste residue and the waste residue intercepted by the filter basket 9 flow through the slag discharge pipe 29 which is fixedly connected to the filter basket 9, and finally enter the collection box 28 fixed on one side of the tank body 1. The collection basket 30 in the collection box 28 collects the waste residue in a centralized manner, so that the waste residue can be collected in an orderly manner, which is convenient for subsequent resource-based disposal and reduces the pollution caused by the random accumulation of waste residue. The collection basket 30 adopts a detachable design. When the waste residue in the collection basket 30 accumulates to a certain amount, it can be removed from the collection box 28 for cleaning. The operation is convenient. The filter basket 9 works in conjunction with the scraping mechanism, the discharge pipe 29, the collection box 28, and the collection basket 30 to intercept, scrape, transport, and collect the waste residue, thereby improving the processing efficiency of the filtration mechanism and reducing equipment maintenance costs.

[0025] In a further preferred embodiment of the present invention, the slag scraping mechanism includes: a first rotating shaft 31 rotatably mounted in the first processing chamber 2 via a sealed bearing, the first rotating shaft 31 being driven by a drive mechanism; a first connecting frame 32 fixed on the first rotating shaft 31; and a first scraper 33 fixed on the first connecting frame 32.

[0026] In this embodiment, when using the slag scraping mechanism of the device, the first rotating shaft 31 is first driven to rotate by the drive mechanism. The first rotating shaft 31 is rotatably installed in the first processing chamber 2 through a sealed bearing, which can reduce leakage problems during the rotation process. When the first rotating shaft 31 rotates, it drives the first connecting frame 32 fixed on it to rotate synchronously, thereby driving the first scraper 33 fixed on the first connecting frame 32 to rotate. During the rotation of the first scraper 33, the waste residue attached to the inner wall of the filter basket 9 is scraped off, so that the scraped waste residue falls into the filter basket 9 and is then transported to the collection box 28 through the slag discharge pipe 29. The first connecting frame 32 plays the role of fixing the first scraper 33, ensuring that the first scraper 33 can stably fit against the inner wall of the filter basket 9 to perform the scraping operation and reduce the residue of the waste residue. The entire slag scraping process is driven by the drive mechanism to drive the first rotating shaft 31, which in turn drives the first connecting frame 32 and the first scraper 33 to work together to effectively scrape the waste residue from the inner wall of the filter basket 9, avoiding the waste residue from clogging the filter basket 9 and affecting the filtration efficiency. At the same time, the setting of the sealed bearing improves the sealing of the rotation of the first rotating shaft 31, reduces the probability of failure during equipment operation, and facilitates the long-term stable operation of the equipment.

[0027] In a further preferred embodiment of the present invention, the conveying mechanism includes: a conveying pipe 36 disposed within the tank body 1; a spiral shaft 39 rotatably mounted within the conveying pipe 36 via a sealed bearing; a plurality of drain pipes 37 fixedly connected to the conveying pipe 36, the inlet ends of the plurality of drain pipes 37 being respectively connected to the first processing chamber 2, the second processing chamber 3, the third processing chamber 4, the fourth processing chamber 5, the fifth processing chamber 6, and the sixth processing chamber 7; and solenoid valves 38 respectively disposed on the drain pipes 37.

[0028] In this embodiment, when using the conveying mechanism of the device, the solenoid valves 38 on each sewage pipe 37 are controlled to open according to the impurity sedimentation of the first processing chamber 2, the second processing chamber 3, the third processing chamber 4, the fourth processing chamber 5, the fifth processing chamber 6 and the sixth processing chamber 7, so that the impurities sedimented in each processing chamber, together with some sewage, flow into the conveying pipe 36 in the tank 1 through the corresponding sewage pipe 37.

[0029] The start-up drive unit drives the spiral shaft 39 inside the conveying pipe 36 to rotate. The spiral shaft 39 is rotatably installed inside the conveying pipe 36 through a sealed bearing, which can reduce leakage problems during rotation. When the spiral shaft 39 rotates, it pushes the impurities and sewage discharged along with it in the conveying pipe 36 to move together for centralized conveying. Multiple sewage pipes 37 are connected to each treatment chamber, so that the impurities and sewage discharged along with them in each treatment chamber can enter the conveying pipe 36 individually or simultaneously. The solenoid valve 38 can control the opening and closing of the corresponding sewage pipe 37, which makes it easy to flexibly adjust the conveying timing according to the amount of impurities settled in each treatment chamber, avoiding excessive accumulation of impurities. The screw shaft 39 cooperates with the conveying pipe 36 to ensure smooth conveying of impurities and associated sewage, reducing blockage. The associated sewage can be collected in a centralized manner for further processing, thereby improving the overall processing efficiency of the equipment. At the same time, the setting of the sealed bearing reduces the probability of equipment failure and facilitates long-term stable operation of the equipment.

[0030] In a further preferred embodiment of the present invention, the tank 1 is provided with an exhaust mechanism for discharging waste gas from the treatment chamber. The exhaust mechanism includes: a filter box 49 disposed inside the tank 1; a guide pipe 51 fixedly connected to the filter box 49, the inlet end of the guide pipe 51 being connected to an outlet 50 opened on one side of the fifth treatment chamber 6 and the sixth treatment chamber 7 respectively; and an outlet pipe 55 fixedly connected to the bottom of the filter box 49, the outlet end of the outlet pipe 55 extending out of the tank 1.

[0031] In this embodiment, when the exhaust mechanism of the device is used, waste gas will be generated in the fifth processing chamber 6 and the sixth processing chamber 7 during the operation of the device. The waste gas is discharged through the air outlet 50 opened on one side of the two processing chambers and enters the air guide pipe 51 connected to the air outlet 50. The air guide pipe 51 transports the waste gas to the filter box 49 set in the tank 1. After the exhaust gas enters the filter box 49, it undergoes preliminary purification treatment to remove some impurities from the exhaust gas. The filter box 49 plays a buffering and filtering role for the exhaust gas, so that the exhaust gas can flow smoothly. The air guide pipe 51 is fixedly connected to the filter box 49 to ensure that there is no leakage during the exhaust gas transportation process. At the same time, it realizes the centralized collection and transportation of exhaust gas from the fifth treatment chamber 6 and the sixth treatment chamber 7. The exhaust gas after being treated by the filter box 49 is discharged through the exhaust pipe 55 fixedly connected to the bottom of the filter box 49. The exhaust end of the exhaust pipe 55 extends out of the tank body 1, so that the treated exhaust gas can be discharged to the designated area. The exhaust mechanism is fully assembled on the tank body 1 to realize the orderly discharge of exhaust gas in the treatment room, reduce the impact of exhaust gas accumulation on the sewage treatment effect, and at the same time reduce the environmental impact caused by direct discharge of exhaust gas.

[0032] In a further preferred embodiment of the present invention, the exhaust mechanism further includes: a second rotating shaft 52 rotatably mounted in the filter box 49 via a sealed bearing, the second rotating shaft 52 being driven by a transmission mechanism; a fan blade 53 fixed on the second rotating shaft 52; and a filter plate 54 disposed in the filter box 49 for filtering exhaust gas.

[0033] In this embodiment, when the second rotating shaft 52 rotates, it drives the fan blade 53 fixed on it to rotate synchronously. At the same time, the exhaust gas generated in the fifth processing chamber 6 and the sixth processing chamber 7 enters the air guide pipe 51 through the air outlet 50, and is then transported to the filter box 49 by the air guide pipe 51. The fan blades 53 rotate to drive the gas flow in the filter box 49, and the filter plate 54 filters the exhaust gas to remove some of the odors and reduce the adverse effects of exhaust gas emissions.

[0034] In a further preferred embodiment of the present invention, the driving mechanism includes: an assembly box 62 fixed to one side of the tank body 1; a motor 40 and a reducer 41 disposed in the assembly box 62, the output shaft of the motor 40 being fixedly connected to the input shaft of the reducer 41 via a coupling; a spline tube 42 rotatably mounted in the assembly box 62 via bearings; an electric telescopic rod 65 fixed to the bottom of the assembly box 62, an assembly plate 64 fixed on the push rod of the electric telescopic rod 65; a spline rod 44 rotatably mounted on the assembly plate 64 via bearings, the top end of the spline rod 44 being inserted into the spline tube 42; and components respectively fixed to the reducer 41. The output shaft meshes with two first bevel gears 43 on the spline tube 42; a transmission rod 45 is rotatably mounted inside the tank 1 via a bearing seat; a second bevel gear 46 and a third bevel gear 47 are respectively fixed on the spline rod 44 and the transmission rod 45, and the second bevel gear 46 meshes with the third bevel gear 47; two fourth bevel gears 48 are respectively fixed on the transmission rod 45 and the first rotating shaft 31, and the two fourth bevel gears 48 mesh; and two fifth bevel gears 56 are respectively fixed on the transmission rod 45 and the second rotating shaft 52, and the two fifth bevel gears 56 mesh.

[0035] In this embodiment, when using the drive mechanism of the device, the motor 40 in the assembly box 62 is started first. The output shaft of the motor 40 drives the reducer 41 through the coupling. The reducer 41 adjusts the speed of the motor 40. Then, through the meshing of two first bevel gears 43 fixed on the output shaft of the reducer 41 and the spline tube 42, the spline tube 42 is driven to rotate in the assembly box 62 through the bearing. When the spline tube 42 rotates, it drives the spline rod 44 inserted inside it to rotate synchronously.

[0036] The electric telescopic rod 65 at the bottom of the assembly box 62 can adjust the lifting and lowering of the assembly plate 64, which in turn drives the spline rod 44, which is mounted on the assembly plate 64 via bearings, to move up and down, adjusting the mating depth between the spline rod 44 and the spline tube 42. When the spline rod 44 rotates, it meshes with the third bevel gear 47 on the transmission rod 45 via the second bevel gear 46 on it, driving the transmission rod 45 to rotate within the tank 1 via the bearing seat, thus realizing the transmission of power.

[0037] When the transmission rod 45 rotates, it drives the first rotating shaft 31 to rotate through the meshing of the two fourth bevel gears 48 on it, and at the same time drives the second rotating shaft 52 to rotate through the meshing of the two fifth bevel gears 56. This allows the drive mechanism to provide power to the slag scraping mechanism and the exhaust mechanism simultaneously. The electric telescopic rod 65 allows the power transmission to be flexibly adjusted, improving the flexibility and coordination of equipment operation.

[0038] In a further preferred embodiment of the present invention, a sixth bevel gear 57 is fixed to the bottom end of the spline rod 44, and a seventh bevel gear 58 is fixed to the spiral shaft 39. The seventh bevel gear 58 and the sixth bevel gear 57 can mesh with each other.

[0039] In this embodiment, during the removal of impurities, the electric telescopic rod 65 is activated first. The push rod of the electric telescopic rod 65 extends, causing the assembly plate 64 fixed on its push rod to descend. When the assembly plate 64 descends, it causes the spline rod 44, which is rotatably mounted on it through the bearing, to descend synchronously. This causes the sixth bevel gear 57 fixed at the bottom end of the spline rod 44 to mesh with the seventh bevel gear 58 on the spiral shaft 39. At the same time, the second bevel gear 46 on the spline rod 44 separates from the third bevel gear 47 on the transmission rod 45. The spline rod 44 rotates continuously, and through the meshing transmission of the sixth bevel gear 57 and the seventh bevel gear 58, it drives the spiral shaft 39 to rotate inside the conveying pipe 36. When the spiral shaft 39 rotates, it pushes the impurities and associated sewage in the conveying pipe 36 to move and carry them in a centralized manner. At this time, the power of the drive mechanism is transmitted to the conveying mechanism through the spline rod 44, the sixth bevel gear 57, and the seventh bevel gear 58, so as to realize the independent operation of the conveying mechanism. In a further preferred embodiment of the present invention, the top of the fourth treatment chamber 5 is provided with a detachable second cover plate 17, and a second water inlet pipe 18 is fixedly connected to the second cover plate 17 for connecting to the domestic sewage pipe of the highway service area. The tops of the fifth treatment chamber 6 and the sixth treatment chamber 7 are respectively provided with detachable third cover plates 63.

[0040] In this embodiment, the sewage pipe of the highway service area is connected to the second water inlet pipe 18 fixedly connected on the second cover plate 17, so that the sewage generated in public toilets and other areas is introduced into the fourth treatment chamber 5. At the same time, the second cover plate 17 is detachably installed on the top of the fourth treatment chamber 5, so that it can be opened as needed to inspect the interior of the fourth treatment chamber 5. The tops of the fifth treatment chamber 6 and the sixth treatment chamber 7 are respectively equipped with removable third covers 63. The third covers 63 can seal and protect the two treatment chambers, preventing external debris from entering the treatment chambers and affecting the sewage treatment effect. At the same time, the third covers 63 can be opened to maintain the internal components of the fifth treatment chamber 6 and the sixth treatment chamber 7 according to the equipment operation requirements. Both the second cover plate 17 and the third cover plate 63 are designed to be detachable, making them easy to operate. This ensures the airtightness of each treatment chamber, preventing sewage leakage or odor spread, and also facilitates the maintenance and cleaning of the fourth treatment chamber 5, the fifth treatment chamber 6, and the sixth treatment chamber 7 by staff, improving the convenience of equipment maintenance and ensuring stable equipment operation.

[0041] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, both the first processing chamber 2 and the second processing chamber 3 are provided with oil drain ports 14. The oil drain ports 14 are used to discharge separated catering oil. An oil drain pipe is fixedly connected to the oil drain port 14 for connecting to a collection device. A drain pipe 59 is fixedly connected to one side of the collection box 28. A baffle 60 is slidably installed inside the drain pipe 59. A connecting rod 61 is fixedly connected to the bottom of the baffle 60. The bottom end of the connecting rod 61 is fixedly connected to the assembly plate 64.

[0042] In this embodiment, when using the oil and liquid discharge structure of the device, after the first treatment chamber 2 and the second treatment chamber 3 treat the oily wastewater, the separated catering oil is discharged through the oil discharge port 14 provided on the two treatment chambers. The oil discharge pipe fixedly connected to the oil discharge port 14 is connected to the external collection device, so that the separated catering oil can be collected and processed in a centralized manner. The waste residue collected in the collection box 28 will be accompanied by some sewage. When it is necessary to discharge this sewage, the connecting rod 61 can be moved by the movement of the assembly plate 64. The connecting rod 61 will drive the baffle 60 to slide in the drain pipe 59, thereby opening the drain pipe 59 and allowing the sewage in the collection box 28 to be discharged through the drain pipe 59, thus achieving the separation and treatment of waste residue and sewage. The oil drain port 14 works in conjunction with the oil drain pipe to achieve orderly discharge and centralized collection of catering oil, improving the convenience of oil resource utilization. The drain pipe 59, baffle 60, connecting rod 61, and assembly plate 64 work together to allow the wastewater in the collection box 28 to be discharged flexibly, reducing the accumulation of wastewater in the collection box 28. At the same time, the close cooperation of each structure improves the coordination of equipment operation and reduces maintenance costs.

[0043] In another embodiment of the present invention, a diversion pipe 22 is provided in the ecological pond 8. The inlet end of the diversion pipe 22 is connected to the fourth conduit 21. A mesh plate 23 is provided above the diversion pipe 22. A filter material layer 24 is provided above the mesh plate 23. A woven bag layer 25 is provided on the filter material layer 24. A soil covering layer 26 is provided on the woven bag layer 25 for planting green plants. An overflow pipe 27 is fixedly connected to one side of the ecological pond 8.

[0044] In this embodiment, the treated wastewater in the sixth treatment chamber 7 flows into the ecological pond 8 through the fourth conduit 21. The fourth conduit 21 is connected to the inlet end of the diversion pipe 22, so that the wastewater first enters the diversion pipe 22 and is diverted by the diversion pipe 22 to guide the wastewater to flow evenly into different areas of the ecological pond 8. A mesh plate 23 is installed above the diversion pipe 22. The mesh plate 23 performs preliminary filtration on the sewage flowing into the ecological pond 8, intercepting the fine impurities remaining in the sewage. Above the mesh plate 23, a filter media layer 24, a woven bag layer 25, and a soil covering layer 26 are arranged in sequence. The filter media layer 24 further filters the sewage. The woven bag layer 25 serves to support the filter media and the soil covering layer 26. Green plants are planted on the soil covering layer 26. The green plants and the filter layers work together to purify the sewage. After being purified by the various layers of the ecological pond 8 and the green plants, the wastewater is discharged through the overflow pipe 27 fixedly connected to one side of the ecological pond 8 when the water level reaches a certain height. The overflow pipe 27 can prevent the water level in the ecological pond 8 from being too high, and the diversion pipe 22 makes the wastewater evenly distributed, improving the purification effect. The combination of each filter layer and green plants enhances the comprehensiveness of wastewater purification. The overflow pipe 27 ensures the orderly discharge of wastewater and helps to realize the recycling of water resources.

[0045] In another embodiment of the present invention, a second connecting frame 34 is fixed on the first rotating shaft 31, and a second scraper 35 is fixed on the second connecting frame 34. The second scraper 35 contacts the bottom inner wall of the first processing chamber 2.

[0046] In this embodiment, when the first rotating shaft 31 rotates, it drives the second connecting frame 34 fixed on it to rotate synchronously. The second connecting frame 34 drives the second scraper 35 fixed on it to rotate. Since the second scraper 35 is in contact with the bottom inner wall of the first processing chamber 2, it can scrape off the impurities deposited at the bottom of the first processing chamber 2, reduce the adhesion of impurities, and facilitate subsequent impurity discharge.

[0047] In summary, compared with related technologies, this method achieves low-carbon treatment and resource utilization of domestic sewage from highway service areas by using multiple treatment chambers within the tank 1 for graded treatment, in conjunction with the coordinated operation of the filtration, conveying, and exhaust mechanisms. Impurities are intercepted and scraped off using the filter basket 9, the first scraper 33, and the second scraper 35, and catering grease is recovered through the oil outlet 14. The sewage is further purified through the ecological pond 8, and the power transmission is flexibly switched by the drive mechanism.
