Description

Technical Field

[0001] This invention relates to the field of rural domestic sewage treatment technology, and more specifically to a mobile emergency treatment device for rural domestic sewage. Background Technology

[0002] Rural domestic sewage refers to wastewater generated by rural residents in their daily lives, mainly including wastewater from washing, bathing, cooking, and toilet flushing. Rural domestic sewage contains a large amount of organic matter, such as food scraps, detergents, and human and animal excrement. Due to the use of detergents and fertilizers, the sewage has high levels of nutrients such as nitrogen and phosphorus, easily leading to eutrophication of water bodies. The sewage also contains a large amount of suspended solids, such as silt and fibers. If this type of sewage is discharged directly into rivers, lakes, and other water bodies without effective treatment, it will cause water quality deterioration, affect the survival of aquatic organisms, and seriously impact the rural ecological environment and residents' health. Therefore, the scientific and rational treatment of rural domestic sewage is of great significance for improving the rural living environment, protecting water resources, and promoting sustainable development. Rural domestic sewage treatment has always been one of the major environmental problems facing China. Traditional domestic sewage treatment technologies are mostly centralized treatment models, which are costly and difficult to implement in small, scattered villages.

[0003] A search revealed that CN118851505A discloses an invention suitable for rural domestic sewage treatment equipment, including a treatment tank and a drain pipe installed on one side of the treatment tank. A filtration and slag discharge mechanism is installed on one side of the treatment tank, and the filtration and slag discharge mechanism is equipped with a screening mechanism. A sewage treatment mechanism is installed on the inner surface of the treatment tank. A floating mechanism is installed inside the treatment tank. A slag collection mechanism is installed at one end of the treatment tank, and the slag collection mechanism is equipped with a rebound mechanism. The invention utilizes a low-speed motor to drive a support shaft, which rotates five rotating plates to filter sewage through a screen. During this process, the side plates are intermittently rotated to open the slag discharge port, automatically discharging waste slag onto the screen for collection. Furthermore, the rotation of the support shaft drives the floating plates to move left and right, allowing plant roots to move within the treatment tank, flushing away attached impurities, preventing blockage of root pores, and promoting oxygen absorption and sewage degradation by the roots. This application utilizes a support shaft to drive five rotating plates to filter sewage through a screen, and can intermittently rotate the side plates to open the slag discharge port, allowing waste slag to be discharged intermittently.

[0004] While the aforementioned rural domestic sewage treatment equipment employs an intermittent automatic discharge method to treat waste residue during the degradation treatment of rural domestic sewage, rural domestic sewage often contains oddly shaped solid impurities such as pesticide bottles and plant roots. Traditional sewage degradation treatment equipment struggles to effectively pre-treat and remove these impurities, which can negatively impact the subsequent degradation effect on rural domestic sewage. Therefore, it is particularly important to improve existing treatment devices and design a new type of mobile emergency treatment device for rural domestic sewage to address these technical deficiencies and enhance the overall practicality of the treatment device. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile emergency treatment device for rural domestic sewage. The guiding component utilizes the rotation of the guiding auger and the filtering effect of the screen to guide and pre-treat and remove solid impurities, preventing them from affecting the subsequent sewage treatment effect. At the same time, the stirring component utilizes the interaction of the rotating frame, rotating plate, scraper, drive gear and internal gear ring to achieve full mixing and stirring of sewage and sewage treatment agents, improving the efficiency and quality of sewage treatment. Meanwhile, the cleaning effect of the scraper on the inner wall of the treatment tank also prevents the adhesion and accumulation of impurities, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mobile emergency treatment device for rural domestic sewage includes a mobile shell body, a guide component at the top of the mobile shell body, a treatment tank located below the guide component and inside the mobile shell body, a stirring component inside the treatment tank, and a sedimentation tank fixedly connected to the bottom of the treatment tank.

[0008] The guiding assembly is used to guide solid impurities. The guiding assembly consists of a connecting cylinder, a guiding bucket, a guiding auger, and a first connecting shell. The connecting cylinder is fixedly connected to the top of the movable shell body, the guiding bucket is fixedly connected to the top of the connecting cylinder, the guiding auger is rotatably connected to the inside of the connecting cylinder, and the first connecting shell is fixedly connected to the bottom of the connecting cylinder and located inside the movable shell body.

[0009] The stirring assembly is used to stir the liquid inside the treatment tank.

[0010] In this invention, the method of using the movable shell body is as follows: Solid impurities in rural domestic sewage, such as pesticide bottles and cans, plant roots and branches, are first introduced into the guide hopper. The first drive motor is started, which drives the guide auger to rotate inside the connecting cylinder. The rotating guide auger guides the solid impurities, causing them to move downwards along the connecting cylinder and finally fall into the first connecting shell. At the same time, the multiple sets of through holes inside the guide auger and the screen at the bottom of the connecting cylinder work together to filter out the water carried by the solid impurities. The solid impurities accumulate on the first filter screen. The telescopic cylinder is activated, which drives the closing plate to slide, closing or opening the through slot, thereby controlling the discharge of solid impurities. When the closing plate closes the through slot, liquid is discharged through the first filter screen. When the closing plate opens the through slot, the solid impurities are discharged from the first connecting shell under the guidance of the first guide frame. The pre-treated sewage then flows through the first connecting shell. After being filtered again through the second connecting shell and the second filter screen, the wastewater is introduced into the treatment tank. At the same time, wastewater treatment agents are added into the treatment tank through the dosing pipe. The second drive motor is started, which drives the rotating frame to rotate inside the treatment tank. The rotation of the rotating frame causes the rotating plate to rotate and shift around the rotating frame as the center. The scraper on the rotating plate cleans the inner wall of the treatment tank while rotating to prevent impurities from adhering. The rotation of the rotating frame also drives the drive gear to shift. The drive gear meshes with the internal gear ring, causing the drive gear to rotate. The rotating drive gear further drives the rotating plate to rotate. After a certain treatment time in the treatment tank, the well-mixed wastewater is discharged into the sedimentation tank through the control valve. In the sedimentation tank, the wastewater is further settled and separated. The clear water is discharged through the drain pipe, and the turbid liquid is discharged through the turbidity drain pipe, thus achieving a thorough mixing of wastewater and wastewater treatment agents.

[0011] As a preferred embodiment of the present invention, the external structure size of the guide auger corresponds to the internal structure size of the connecting cylinder, and the guide auger extends to the outside of the connecting cylinder and is fixedly connected to the drive end of the first drive motor.

[0012] As a preferred embodiment of the present invention, the guide auger has multiple sets of through holes inside, the bottom of the connecting cylinder is fixedly connected to a connecting frame, and a screen is fixedly connected inside the connecting frame.

[0013] As a preferred embodiment of the present invention, a first filter screen is fixedly connected to the bottom of the interior of the first connecting shell. The first filter screen has an inclined structure design. A first guide frame is fixedly connected to the outer side of the first connecting shell. A through groove is opened at the end of the first connecting shell near the first guide frame.

[0014] As a preferred embodiment of the present invention, a closing plate is slidably connected to one end of the first guide frame near the first connecting shell, and a drive end of a telescopic cylinder is fixedly connected to the top of the closing plate, the telescopic cylinder being fixedly connected to the first connecting shell.

[0015] As a preferred embodiment of the present invention, a second connecting shell is fixedly connected to the bottom of the connecting cylinder and the end away from the first connecting shell. The second connecting shell is located below the screen. The interior of the second connecting shell has an inclined structure design. A second filter screen is fixedly connected to the bottom of the interior of the second connecting shell. The first connecting shell is connected to the second connecting shell through a second guide frame. The second connecting shell is connected to the processing tank through a third guide frame.

[0016] As a preferred embodiment of the present invention, the stirring assembly comprises a rotating frame, multiple sets of rotating plates, multiple sets of scrapers, an internal gear ring, and multiple sets of drive gears. The rotating frame is rotatably connected to the inside of the processing tank. The multiple sets of rotating plates are rotatably connected to the four sides of the inside of the rotating frame. The multiple sets of scrapers are slidably connected to both ends of the rotating plates. The internal gear ring is fixedly connected to the bottom of the inside of the processing tank. The multiple sets of drive gears are rotatably connected to the four sides of the bottom of the rotating frame.

[0017] As a preferred embodiment of the present invention, the scraper extends into the interior of the rotating plate and is fixedly connected to a telescopic rod. A compression spring is sleeved on the outer side of the telescopic rod. Multiple sets of the telescopic rods are connected by a connecting strip. The connecting strip is slidably connected to the rotating plate. The drive end of the electric telescopic rod is fixedly connected to the outer side of the connecting strip.

[0018] As a preferred embodiment of the present invention, the drive gear is meshed with the internal gear ring, the drive gear is fixedly connected to the rotating plate, and the drive end of the second drive motor is fixedly connected to the top of the rotating frame and located at the top of the processing tank.

[0019] As a preferred embodiment of the present invention, a control valve is fixedly connected to the top of the sedimentation tank, a dosing pipe is provided on the outside of the treatment tank, and a drain pipe and a turbidity discharge pipe are respectively provided on the outside of the sedimentation tank from top to bottom.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, through the design of the guiding component, the first drive motor is started, which drives the guide auger to rotate inside the connecting cylinder. The rotating guide auger guides the solid impurities, causing them to move downwards along the connecting cylinder and eventually fall into the first connecting shell. At the same time, the multiple sets of through holes inside the guide auger and the screen at the bottom of the connecting cylinder work together to filter out the water carried by the solid impurities. The solid impurities accumulate on the first filter screen. The telescopic cylinder is activated, which drives the closing plate to slide, closing or opening the through slot, thereby controlling the discharge of solid impurities. When the closing plate closes the through slot, the liquid is discharged through the first filter screen. When the closing plate opens the through slot, the solid impurities are discharged from the first connecting shell under the guidance of the first guide frame. The guiding component utilizes the rotation of the guide auger and the filtering effect of the screen to achieve the guidance and pre-treatment and retrieval of solid impurities, preventing them from affecting the subsequent sewage treatment effect.

[0022] 2. In this invention, through the design of the stirring assembly, the second drive motor is activated, which drives the rotating frame to rotate inside the treatment tank. The rotation of the rotating frame causes the rotating plate to rotate and displace around the rotating frame as the center. While rotating, the scraper on the rotating plate cleans the inner wall of the treatment tank to prevent impurities from adhering. The rotation of the rotating frame also drives the drive gear to displace. The drive gear meshes with the internal gear ring, causing the drive gear to rotate. The rotating drive gear further drives the rotating plate to rotate. The stirring assembly utilizes the interaction of the rotating frame, rotating plate, scraper, drive gear, and internal gear ring to achieve thorough mixing and stirring of sewage and sewage treatment agents, improving the efficiency and quality of sewage treatment. At the same time, the cleaning effect of the scraper on the inner wall of the treatment tank also prevents the adhesion and accumulation of impurities. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Example:

[0035] Please see Figures 1-9 The present invention provides a technical solution:

[0036] A mobile emergency treatment device for rural domestic sewage includes a mobile shell body 1, a guide component 2 is provided at the top inside the mobile shell body 1, a treatment tank 3 is provided below the guide component 2 and inside the mobile shell body 1, a stirring component 4 is provided inside the treatment tank 3, and a sedimentation tank 31 is fixedly connected to the bottom of the treatment tank 3.

[0037] The guide assembly 2 is used to guide solid impurities. The guide assembly 2 consists of a connecting cylinder 5, a guide bucket 6, a guide auger 7 and a first connecting shell 8. The connecting cylinder 5 is fixedly connected to the top of the movable shell body 1, the guide bucket 6 is fixedly connected to the top of the connecting cylinder 5, the guide auger 7 is rotatably connected to the inside of the connecting cylinder 5, and the first connecting shell 8 is fixedly connected to the bottom of the connecting cylinder 5 and located inside the movable shell body 1.

[0038] The stirring assembly 4 is used to stir the liquid inside the treatment tank 3.

[0039] Furthermore, the external structure size of the guide auger 7 corresponds to the internal structure size of the connecting cylinder 5. The guide auger 7 extends to the outside of the connecting cylinder 5 and is fixedly connected to the drive end of the first drive motor. When the first drive motor is started, the guide auger 7 is driven to rotate. When solid impurities are introduced into the interior of the guide bucket 6 and then into the interior of the connecting cylinder 5 through the guide bucket 6, the rotation of the guide auger 7 guides the solid impurities, so that the fixed impurities are introduced into the interior of the first connecting shell 8 for pretreatment and retrieval, preventing them from affecting the treatment of domestic sewage.

[0040] The guide auger 7 has multiple sets of through holes 9 inside, and a connecting frame 10 is fixedly connected to the bottom of the connecting cylinder 5. A screen 11 is fixedly connected inside the connecting frame 10. When the guide auger 7 guides solid impurities, the through holes 9 and the screen 11 are used to filter the moisture carried by the solid impurities.

[0041] Secondly, a first filter screen 12 is fixedly connected to the bottom of the first connecting shell 8. The first filter screen 12 has an inclined structure design. A first guide frame 13 is fixedly connected to the outside of the first connecting shell 8. A through groove 14 is opened at one end of the first connecting shell 8 near the first guide frame 13. A closing plate 15 is slidably connected to one end of the first guide frame 13 near the first connecting shell 8. The top of the closing plate 15 is fixedly connected to the drive end of a telescopic cylinder. The telescopic cylinder is fixedly connected to the first connecting shell 8. When solid impurities fall on the top of the first filter screen 12, the telescopic cylinder is activated, which drives the closing plate 15 to move, so that the closing plate 15 can close the through groove 14. The solid impurities are filtered by the first filter screen 12, allowing the liquid to be discharged. The closing plate 15 is reset, allowing the through groove 14 to open. The solid impurities are guided by the first guide frame 13, allowing them to be discharged from the interior of the first connecting shell 8 for collection and treatment.

[0042] Furthermore, a second connecting shell 16 is fixedly connected to the bottom of the connecting cylinder 5 and the end furthest from the first connecting shell 8. The second connecting shell 16 is located below the screen 11 and has an inclined internal structure. A second filter screen 17 is fixedly connected to the bottom of the second connecting shell 16. The first connecting shell 8 is connected to the second connecting shell 16 via a second guide frame 18, and the second connecting shell 16 is connected to the treatment tank 3 via a third guide frame 19. When domestic sewage is introduced into the guide bucket 6 and then into the connecting cylinder 5, the sewage is introduced into the second connecting shell 16. At the same time, the sewage filtered by the first filter screen 12 is introduced into the second connecting shell 16 via the second guide frame 18. The second filter screen 17 can filter the sewage again, facilitating sewage treatment. The sewage is then introduced into the treatment tank 3 via the third guide frame 19, where it is treated.

[0043] Furthermore, the stirring assembly 4 consists of a rotating frame 20, multiple sets of rotating plates 21, multiple sets of scrapers 22, an internal gear ring 23, and multiple sets of drive gears 24. The rotating frame 20 is rotatably connected to the inside of the treatment tank 3. The multiple sets of rotating plates 21 are rotatably connected to the four sides of the inside of the rotating frame 20. The multiple sets of scrapers 22 are slidably connected to both ends of the rotating plates 21. The internal gear ring 23 is fixedly connected to the bottom of the inside of the treatment tank 3. The multiple sets of drive gears 24 are rotatably connected to the four sides of the bottom of the rotating frame 20. When sewage is introduced into the inside of the treatment tank 3, the stirring assembly 4 can mix the sewage with the sewage treatment agent, thereby effectively treating the sewage.

[0044] Furthermore, a telescopic rod 25 is fixedly connected to the inside of the rotating plate 21 extending from the scraper 22. A compression spring 26 is sleeved on the outside of the telescopic rod 25. Multiple sets of telescopic rods 25 are connected by a connecting strip 27. The connecting strip 27 is slidably connected to the rotating plate 21. The drive end of the electric telescopic rod is fixedly connected to the outside of the connecting strip 27. When the electric telescopic rod is activated, the connecting strip 27 is moved, causing the telescopic rod 25 to move, which in turn causes the scraper 22 to move, so that the scraper 22 contacts the inner wall of the treatment tank 3. When the scraper 22 contacts the inner wall of the treatment tank 3, the compression spring 26 can increase the buffer distance between the scraper 22 and the treatment tank 3, preventing the scraper 22 from damaging the inner wall of the treatment tank 3.

[0045] Furthermore, the drive gear 24 is meshed with the internal gear ring 23, and the drive gear 24 is fixedly connected to the rotating plate 21. The top of the rotating frame 20, located at the top of the treatment tank 3, is fixedly connected to the drive end of the second drive motor. When the second drive motor is started, the rotating frame 20 is driven to rotate, causing the rotating plate 21 to rotate around the rotating frame 20 as the center. At the same time, the rotation of the rotating frame 20 causes the drive gear 24 to move. The drive gear 24 is meshed with the internal gear ring 23, causing the drive gear 24 to rotate, which in turn causes the rotating plate 21 to rotate. While the rotating plate 21 mixes the sewage and sewage treatment agent inside the treatment tank 3, it can also drive the scraper 22 to clean the inner wall of the treatment tank 3, removing the impurities attached to the inner wall.

[0046] Furthermore, a control valve is fixedly connected to the top of the sedimentation tank 31, and a dosing pipe 28 is provided on the outside of the treatment tank 3. A drain pipe 29 and a turbidity discharge pipe 30 are respectively provided on the outside of the sedimentation tank 31 from top to bottom. The wastewater treatment agent can be introduced into the interior of the treatment tank 3 through the dosing pipe 28. After the wastewater treatment agent reacts and mixes fully with the wastewater, the control valve is opened and the wastewater is discharged into the sedimentation chamber at the bottom of the sedimentation tank 31. After sedimentation and purification, the upper layer of clear water is discharged from the drain pipe 29, and the lower layer of turbid liquid is discharged from the turbidity discharge pipe 30, thereby achieving the effect of filtering and purifying wastewater.

[0047] In this embodiment, the specific implementation scenario is as follows: In actual use, solid impurities in rural domestic sewage, such as pesticide bottles and cans, plant roots and branches, are first introduced into the guide hopper 6. The first drive motor is started, which drives the guide auger 7 to rotate inside the connecting cylinder 5. The rotating guide auger 7 guides the solid impurities, causing them to move downwards along the connecting cylinder 5 and eventually fall into the first connecting shell 8. At the same time, the multiple sets of through holes 9 inside the guide auger 7 and the screen 11 at the bottom of the connecting cylinder 5 work together to filter out the water carried by the solid impurities. The solid impurities accumulate on the first filter screen 12. The telescopic cylinder is activated, causing the closing plate 15 to slide, closing or opening the through groove 14, thereby controlling the discharge of solid impurities. When the closing plate 15 closes the through groove 14, liquid is discharged through the first filter screen 12. When the closing plate 15 opens the through groove 14, solid impurities are discharged from the first connecting shell 8 under the guidance of the first guide frame 13. After pretreatment, the sewage is filtered again through the second connecting shell 16 and the second filter screen 17. The wastewater is introduced into the treatment tank 3, and simultaneously, wastewater treatment agents are added into the treatment tank 3 through the dosing pipe 28. The second drive motor is started, which drives the rotating frame 20 to rotate inside the treatment tank 3. The rotation of the rotating frame 20 causes the rotating plate 21 to rotate and shift around the rotating frame 20 as the center. The scraper 22 on the rotating plate 21 cleans the inner wall of the treatment tank 3 while rotating to prevent impurities from adhering. The rotation of the rotating frame 20 also drives the drive gear 24 to shift. The drive gear 24 meshes with the internal gear ring 23, causing the drive gear 24 to rotate. The rotating drive gear 24 further drives the rotating plate 21 to rotate. After a certain treatment time in the treatment tank 3, the well-mixed wastewater is discharged into the sedimentation tank 31 through the control valve. In the sedimentation tank 31, the wastewater is further precipitated and separated. The clear water is discharged through the drain pipe 29, and the turbid liquid is discharged through the turbidity discharge pipe 30, thereby achieving a thorough mixing of wastewater and wastewater treatment agents. Compared with existing treatment devices, the present invention improves the overall practicality of the treatment device through its design.
