Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to a rural sewage treatment device. Background Technology

[0002] Currently, in rural areas, people often wash clothes in rivers, resulting in high levels of LAS (sulfuric acid surfactants) in the river water. This water is then diverted or used elsewhere, leading to a higher concentration of anionic surfactants. LAS also increases the solubility of toxic organic matter in the water, which is harmful to plants and animals, ultimately damaging water resources and endangering human health. Therefore, rural wastewater treatment equipment is needed to address this issue.

[0003] Rural wastewater treatment equipment uses biological, physical, or chemical methods to meet discharge standards, thereby protecting the rural environment and residents' health. These devices are not only highly efficient in purification but also energy-saving, environmentally friendly, space-saving, and easy to operate, bringing significant economic and social benefits. They are widely used in rural residential areas, farmland irrigation, and other places, playing a vital role in improving rural environmental sanitation, enhancing residents' quality of life, and promoting sustainable agricultural development. Regular equipment maintenance is equally important to ensure stable operation and treatment effectiveness, contributing to the construction of beautiful villages.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the actual use of existing rural sewage treatment devices, the cost of filter media remains high, and the removal efficiency of anionic surfactants is relatively low. These two defects severely restrict the actual application efficiency of the treatment system. Utility Model Content

[0005] In order to improve the existing rural sewage treatment devices, which suffer from high filter media costs and low removal efficiency of anionic surfactants, thus severely restricting the practical application efficiency of the treatment system, this application provides a rural sewage treatment device.

[0006] This application provides a rural sewage treatment device with the following technical solution: A rural sewage treatment device includes a base, a purification component on the top surface of the base, and a limiting component on the surface of the purification component. The purification component includes a trapezoidal plate one on the top surface of the base, and a trapezoidal plate two on the top surface of the trapezoidal plate one. A battery is fixed inside the trapezoidal plate two, and a rectangular plate is fixed on the surface of the trapezoidal plate two. A power module is fixed on the surface of the rectangular plate, and a water quality monitor is fixed on the surface of the rectangular plate. A filter box one is provided on the top surface of the trapezoidal plate two, and a water pump is fixed inside the filter box one. An annular seat one is fixed inside the filter box one, and a filter tank is provided on the top of the annular seat one. A water outlet pipe one is fixed on the surface of the filter tank one. A U-shaped block is fixed on the side surface of the filter box one, and the U-shaped block... A rotating frame is mounted on the side surface of the first trapezoidal plate via a rotating shaft. A solar panel is fixed to the surface of the rotating frame. A filter box is fixed to the top surface of the second trapezoidal plate, and a water outlet pipe is fixed to the side surface of the second filter box. An annular seat is fixed to the top surface of the first trapezoidal plate, and a water bottle is placed on the top of the annular seat. A water storage tank is placed on the top surface of the first trapezoidal plate, and an annular column is fixed to the top surface of the first trapezoidal plate. A U-shaped tube is provided between the first filter box and the water storage tank, and a water-stop clamp is provided on the surface of the U-shaped tube. An ultraviolet lamp is fixed to the bottom surface of the rotating frame. A microprocessor is fixed to the top surface of the second trapezoidal plate. A connecting cylinder is fixed to the surface of the U-shaped block. A limit groove is opened on the surface of the connecting cylinder, and a spring is provided inside the connecting cylinder. A protruding post is movably connected inside the connecting cylinder, and a limit post is fixed to the surface of the protruding post.

[0007] By adopting the above technical solution, after the rural sewage is collected in the storage tank, the annular column on the surface of the trapezoidal plate and the water bottle form a lower siphon auxiliary device. This device connects the water bottle and the storage tank through a conduit. The height difference between the storage tank and the filter tank creates a hydrostatic pressure difference. When sewage is injected into the storage tank, the high-level water body generates a siphon effect through the U-shaped pipe structure. Combined with the automatic venting design, it realizes a self-circulating water guide without power. The system adopts a water guide design based on water flow pressure difference. By optimizing the pipeline layout and air pressure balance mechanism, it ensures that sewage is continuously transported to the filter tank under gravity drive, replacing the cumbersome manual water guide and water pump transportation. This saves energy consumption and improves treatment efficiency. At the same time, the microprocessor can control the opening of the solenoid valve at timed intervals to achieve secondary filtration, which is more convenient. The solar panel can directly supply energy under sunlight, or store light and electrical energy for backup of water pumps and ultraviolet lamps on cloudy days. The filter tank is equipped with a filter screen to prevent clogging.

[0008] Further configuration: the surface of the filter box 2 and the filter box 1 is provided with a connecting pipe, and the surface of the connecting pipe is provided with a solenoid valve 1; the left end surface of the trapezoidal plate 1 is provided with a collection box, and the surface of the collection box is fixed with a water outlet pipe 3, and the surface of the water outlet pipe 3 is provided with a solenoid valve 2; the microprocessor is electrically connected to the solenoid valve 1, and the microprocessor is electrically connected to the battery.

[0009] By adopting the above technical solution, the device can be disassembled simply by turning the nut, making installation and disassembly convenient. This achieves the goal of modular manufacturing and an automatic and complete filtration system, which not only saves the market production cost and resources of sewage purification devices and increases the application scenarios and coverage of sewage purification devices, but also enables the purification of daily sewage in a wide range and convenient manner.

[0010] Further configuration includes the following: the bottom surfaces of trapezoidal plate one and trapezoidal plate two, filter box one, water storage tank, and collection box are all fixed with threaded posts, and the surfaces of the threaded posts are connected with nuts by threads; the power module is an MP2315 / MP6206 module, and the power module is electrically connected to the battery and water pump; the solar panel and ultraviolet lamp are electrically connected to the battery.

[0011] By adopting the above technical solution, the water quality monitoring instrument can be used to directly measure the sewage filtration effect, improving the actual use effect. The solar panel, battery, and water pump, driven by photovoltaic energy, generate air pressure to promote the continuous circulation of water, thereby achieving the purpose of repeated filtration of sewage in the first filtration stage. This successfully replaces the previous operation process that required manual operation of the piston to generate air pressure to promote water circulation, greatly improving the operating efficiency and filtration effect of the device.

[0012] Further configuration includes two sets of water bottles arranged symmetrically, connected by conduits, and connected to the water tank via conduits. The surface of the water quality monitor is connected to multiple probes, and the water quality monitor is electrically connected to the battery.

[0013] By adopting the above technical solution, the surface of the trapezoidal plate is provided with an annular column and a water bottle as a lower siphon aid. The water bottle is connected to the water storage tank through a conduit. When rural sewage is injected into the water storage tank, the water level is lower than the conduit, which replaces the cumbersome manual water guiding and water pumping, saving electricity consumption and improving treatment efficiency.

[0014] Further, an L-tube is fixed to the side surface of the water bottle, and the interior of both the second filter box and the filter canister are filled with earthworm castings and maifanite as filter media. The second filter box is also filled with a titanium dioxide film and a layer of iron oxide particles. The filter canister is connected to the water pump via a conduit.

[0015] By adopting the above technical solution, secondary filtration is performed using filter box two, which improves the filtration effect and makes it easier to replace the filter media inside filter box two.

[0016] Further, the limiting component includes a rectangular cover on the top surface of the filter box 2, and a sleeve is fixed on the top surface of the rectangular cover. The sleeve has a sliding groove on its surface and a spring inside. A protruding post is movably connected inside the sleeve, and a sliding post is fixed on the surface of the protruding post. An acrylic plate is fixed on the top surface of the rectangular cover, and a support frame is fixed on the top surface of the rectangular cover.

[0017] Further configuration: the first protrusion passes through the rectangular cover and the second filter box in sequence, and extends into the interior of the second filter box; the surface of the sliding column contacts the inner wall of the sliding groove.

[0018] By adopting the above technical solution, the sliding column can slide in the sliding groove, and the sliding column and the convex column are fixedly connected to form an integrated structure, which enhances the stability and sliding accuracy of the structure. By sliding the convex column, the convex column can be separated from the filter box, and the rectangular cover can be slid to replace the filter material inside the filter box.

[0019] Compared with related technologies, the rural sewage treatment device provided by this utility model has the following beneficial effects:

[0020] This utility model provides a rural sewage treatment device. A purification component is installed on the surface of the base, comprising a water storage tank, a water pump, a first filter box, and a second filter box. After rural sewage is collected in the water storage tank, the annular column on the surface of the trapezoidal plate and a water bottle form a lower siphon auxiliary device. This device connects the water bottle to the water storage tank via a conduit. Utilizing the height difference between the water storage tank and the first filter box, a hydrostatic pressure difference is created. When sewage is injected into the water storage tank, the higher-level water body generates a siphon effect through the U-shaped pipe structure. Combined with an automatic venting design, it achieves a self-circulating water flow without power. This system adopts a water flow design based on water pressure difference. Through optimized pipeline layout and air pressure balance mechanism, it ensures that sewage is continuously transported to the first filter box under gravity drive, replacing cumbersome manual water flow and water pump operation. The installation of solar panels, batteries, and the water pump, driven by photovoltaic energy, generates air pressure that promotes continuous water circulation, thus achieving repeated filtration of sewage in the first filtration stage. The purpose is to improve the filtration effect by mixing common earthworm castings and activated carbon in both the filter box and the filter canister. Both earthworm castings and activated carbon have porous structures, large surface areas, and strong adsorption capacity. They are made into a percolation medium and filled into the sewage purification device. Sewage is then passed through this mixed medium to slowly percolate and effectively remove harmful substances such as LAS from the sewage. The bottom surface of the rotating frame is equipped with an ultraviolet lamp, and the top surface of the rectangular cover is equipped with an acrylic plate. The titanium dioxide film can perform photocatalysis for deeper sterilization under ultraviolet light. The iron oxide granular layer assists the activated carbon in adsorbing heavy metal ions. By sliding the second protrusion, the second protrusion can be separated from the round hole on the surface of the rotating frame, making it easy to adjust the rotating frame to a suitable angle. At the same time, the solar panel on the surface of the rotating frame can directly supply energy under sunlight, and can also store light and electrical energy for backup of the water pump and ultraviolet lamp on cloudy days.

[0021] This utility model provides a rural sewage treatment device, which uses a limiting component on the surface of the filter box two. The limiting component has a sleeve and a protrusion. When the user slides the protrusion, the protrusion moves and separates from the filter box two. Then, by sliding the rectangular cover, the filter material inside the filter box two can be replaced.

A U-shaped block 211 is fixed to the side surface of the filter box 207, and a rotating frame 212 is mounted on the side surface of the U-shaped block 211 via a rotating shaft.

A connection is provided between the filter box 207 and the water storage tank 218. The U-shaped tube 220 has a water-stop clamp 221 on its surface. An ultraviolet lamp 232 is fixed on the bottom surface of the rotating frame 212. A microprocessor 233 is fixed on the top surface of the trapezoidal plate 202. A connecting cylinder 234 is fixed on the surface of the U-shaped block 211. A limit groove 235 is opened on the surface of the connecting cylinder 234. A spring 236 is provided inside the connecting cylinder 234. A protruding post 237 is movably connected inside the connecting cylinder 234. A limit post 238 is fixed on the surface of the protruding post 237.

[0031] like Figure 1-5As shown, the purification component 2 includes a water storage tank 218, a water pump 231, a first filter box 207, and a second filter box 214. Rural sewage is injected into the water storage tank 218. Since there is a height difference between the water storage tank 218 and the first filter box 207, a water pressure difference design is adopted to avoid excessive reliance on electricity and to implement the concept of energy conservation and emission reduction. The water pressure difference design replaces cumbersome manual water guiding and water pumping, saving electricity and improving treatment efficiency. The rotating frame 212 has multiple sets of circular holes on its surface, which contact the surface of the second protrusion 237 to limit the movement of the rotating frame 212. The solar panel 213 on the surface of the rotating frame 212 can directly supply energy under sunlight or store solar and electrical energy for use on cloudy days for the water pump 231 and ultraviolet lamp 232. The filter tank 209 has a filter screen inside to prevent clogging.

[0032] like Figure 1-5 As shown, the surfaces of filter box 214 and filter box 207 are provided with connecting pipes 222, and the surface of connecting pipe 222 is provided with solenoid valve 223. The left end surface of trapezoidal plate 201 is provided with collection box 224, and the surface of collection box 224 is fixed with water outlet pipe 225, and the surface of water outlet pipe 225 is provided with solenoid valve 226. Microprocessor 233 is electrically connected to solenoid valve 223, and microprocessor 233 is electrically connected to battery 203.

[0033] like Figure 1-5 As shown, the bottom surfaces of trapezoidal plate 201, trapezoidal plate 202, filter box 207, water tank 218, and collection box 224 are all fixed with threaded posts 227, and the surface of the threaded posts 227 is connected to nuts 228 by threads. The power module 205 is an MP2315 / MP6206 module, and the power module 205 is electrically connected to the battery 203 and the water pump 231. The solar panel 213 and the ultraviolet lamp 232 are electrically connected to the battery 203.

[0034] like Figure 1-5 As shown, it can be disassembled by turning nut 228. The installation and disassembly are simple, realizing the purpose of modular manufacturing and automatic complete filtration system. It can not only save the market production cost and resources of sewage purification device, and improve the application scenarios and coverage of sewage purification device, but also purify daily sewage in a wide range and convenient way.

[0035] like Figure 1-5 As shown, there are two sets of water bottles 217, which are symmetrically arranged. The water bottles 217 are connected to each other by conduits, and the water bottles 217 are connected to the water tank 218 by conduits. The surface of the water quality monitor 206 is connected to multiple probes, and the water quality monitor 206 is electrically connected to the battery 203.

[0036] like Figure 1-5 As shown, the water quality monitor 206 allows for direct measurement of wastewater filtration efficiency, improving practical performance. The solar panel 213, battery 203, and water pump 231, driven by photovoltaic energy, generate air pressure to promote continuous water circulation, thus achieving repeated filtration of wastewater in the first filtration stage. This successfully replaces the previous manual piston-pulling process that required air pressure to promote water circulation, greatly improving the device's operating efficiency and filtration effect.

[0037] like Figure 1-5 As shown, an L-tube 230 is fixed to the side surface of the water bottle 217. The interior of the filter box 214 and the filter canister 209 are filled with earthworm castings and maifan stone as filter media. The filter box 214 is also filled with a titanium dioxide film and a layer of iron oxide particles. The filter canister 209 is connected to the water pump 231 through a conduit.

[0038] like Figure 1-5 As shown, the surface of the trapezoidal plate 201 is provided with annular column 219 and water bottle 217 as a lower siphon aid. The water bottle 217 is connected to the water storage tank 218 through a conduit. When rural sewage is injected into the water storage tank 218, the water level is lower than the conduit, which replaces the cumbersome manual water guiding and water pumping, saving electricity consumption and improving treatment efficiency.

[0039] In implementation, the purification component 2 includes a water storage tank 218, a water pump 231, a first filter box 207, and a second filter box 214. After rural sewage is collected by the water storage tank 218, the annular column 219 on the surface of the trapezoidal plate 201 and the water bottle 217 form a lower siphon auxiliary device. This device connects the water bottle 217 to the water storage tank 218 through a conduit. Utilizing the height difference between the water storage tank 218 and the first filter box 207, a hydrostatic pressure difference is created. When sewage is injected into the water storage tank 218, the higher-level water body flows through the U-shaped... The structure of pipe 220 generates a siphon effect, combined with an automatic venting design, to achieve self-circulating water guidance without power. This system employs a water guidance design based on water pressure difference, optimizing the pipeline layout and air pressure balance mechanism to ensure that wastewater is continuously transported to filter box 207 under gravity drive, replacing cumbersome manual water guidance and pump operation. This saves energy and improves treatment efficiency. Power module 205 controls pump 231 to start, transporting water from filter box 207 to filter tank 20. Inside the filter 9, air pressure is generated to promote continuous water circulation, thereby achieving the purpose of repeated filtration of sewage in the first filtration stage. This successfully replaces the previous method of manually pulling a piston to control the start of solenoid valve 223. The filtered sewage enters the filter box 214 through the connecting pipe 222 for secondary filtration. After filtration, it enters the collection box 224 through the outlet pipe 215. At the same time, the filter box 214 and the filter tank 209 mix common earthworm castings and charcoal as filter materials, which greatly improves the filtration effect. The bottom surface of the rotating frame 212 is equipped with an ultraviolet lamp 232, and the top surface of the rectangular cover 301 is equipped with an acrylic plate 307. The titanium dioxide film can achieve deeper sterilization through photocatalysis under ultraviolet light. The iron oxide granular layer assists the activated carbon in adsorbing heavy metal ions. By sliding the protrusion 237, the protrusion 237 can be separated from the round hole on the surface of the rotating frame 212, making it easy to adjust the rotating frame 212 to a suitable angle.

[0040] Example 2:

[0041] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: the limiting component 3 includes a rectangular cover 301 disposed on the top surface of the filter box 214, and a sleeve 302 is fixed on the top surface of the rectangular cover 301. A sliding groove 303 is opened on the surface of the sleeve 302, and a spring 304 is provided inside the sleeve 302. A protrusion 305 is movably connected inside the sleeve 302, and a sliding post 306 is fixed on the surface of the protrusion 305. An acrylic plate 307 is fixed on the top surface of the rectangular cover 301, and a support frame 308 is fixed on the top surface of the rectangular cover 301.

[0042] like Figure 1-5As shown, secondary filtration is performed using filter box 214 to improve the filtration effect. At the same time, it is convenient to replace the filter media inside filter box 214, and the support frame 308 can easily support the rotating frame 212.

[0043] like Figure 1-5 As shown, the first protrusion 305 passes through the rectangular cover 301 and the second filter box 214 in sequence, and extends into the interior of the second filter box 214. The surface of the sliding column 306 contacts the inner wall of the sliding groove 303.

[0044] like Figure 1-5 As shown, the sliding column 306 can slide within the sliding groove 303, and the sliding column 306 and the protruding column 305 are fixedly connected to form an integrated structure, which enhances the stability and sliding accuracy of the structure.

[0045] During implementation, when it is necessary to replace the filter media inside filter box 214 and filter canister 209, filter canister 209 engages with annular seat 208, allowing for direct replacement. By sliding the sliding column 306, the sliding column 306 can drive the protruding column 305 to slide, thereby separating the protruding column 305 from filter box 214, and then sliding the rectangular cover 301 to replace the filter media inside filter box 214.

[0046] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0047] 1. The purification component 2 includes a water storage tank 218, a water pump 231, a first filter box 207, and a second filter box 214. After rural sewage is collected by the water storage tank 218, the annular column 219 on the surface of the trapezoidal plate 201 and the water bottle 217 form a lower siphon auxiliary device. This device connects the water bottle 217 to the water storage tank 218 through a conduit. Utilizing the height difference between the water storage tank 218 and the first filter box 207 to create a hydrostatic pressure difference, when sewage is injected into the water storage tank 218, the higher water level generates a siphon effect through the U-shaped pipe 220 structure. Combined with the automatic venting design, a self-circulating system without power is achieved. The system employs a water guiding design based on water flow pressure difference. By optimizing the pipeline layout and air pressure balance mechanism, it ensures that sewage is continuously transported to filter box 207 under gravity drive, replacing cumbersome manual water guiding and water pump delivery. The solar panel 213, battery 203, and water pump 231, driven by photovoltaic energy, generate air pressure to promote continuous water circulation, thereby achieving the purpose of repeated filtration of sewage in the first step of filtration. At the same time, filter box 214 and filter tank 209 mix common earthworm castings and charcoal as filter materials to improve the filtration effect.

When the user slides the protrusion 305, the protrusion 305 moves, thereby separating the protrusion 305 from the filter box 214. Then, by sliding the rectangular cover 301, the filter material inside the filter box 214 can be replaced.

[0049] In this technical solution, the purification component 2 includes a water storage tank 218, a water pump 231, a first filter box 207, and a second filter box 214. After rural sewage is collected by the water storage tank 218, the annular column 219 on the surface of the trapezoidal plate 201 and the water bottle 217 form a lower siphon auxiliary device. This device connects the water bottle 217 to the water storage tank 218 via a conduit. Utilizing the height difference between the water storage tank 218 and the first filter box 207, a hydrostatic pressure difference is created. When sewage is injected into the water storage tank 218, the higher-level water body generates a siphon effect through the U-shaped pipe 220 structure. Combined with an automatic venting design, this achieves a self-circulating water guide without power. This system adopts a water guide design based on water flow pressure difference, and optimizes the pipeline layout. A pressure balance mechanism ensures that wastewater is continuously transported to filter box 207 under gravity, replacing cumbersome manual water guiding and pumping. This saves energy and improves treatment efficiency. Power module 205 controls pump 231 to transport water from filter box 207 to filter tank 209, generating pressure to promote continuous water circulation. This achieves repeated filtration of wastewater in the first filtration stage, successfully replacing the previous method of manually pulling a piston to control solenoid valve 223. The filtered wastewater enters filter box 214 through connecting pipe 222 for secondary filtration, and then flows through outlet pipe 215 into collection box 2. Inside filter 24, filter box 214 and filter tank 209 mix common earthworm castings with maifanite and activated carbon as filter materials, greatly improving the filtration effect. Since the bottom surfaces of trapezoidal plate 201, trapezoidal plate 202, filter box 207, water tank 218, and collection box 224 are all fixed with threaded posts 227, they can be disassembled by turning the nuts 228. The modular design makes installation and disassembly simple. The water quality monitor 206 allows for direct measurement of wastewater filtration, improving practical performance. The bottom surface of the rotating frame 212 is equipped with an ultraviolet lamp 232, and the top surface of the rectangular cover 301 is equipped with an acrylic plate 307 for carbon dioxide... The titanium film can achieve deeper sterilization through photocatalysis under ultraviolet light. The iron oxide granular layer assists the activated carbon in adsorbing heavy metal ions. By sliding the second protrusion 237, the protrusion 237 can be separated from the circular hole on the surface of the rotating frame 212, making it easy to adjust the rotating frame 212 to a suitable angle. When it is necessary to replace the filter material inside the filter box 214 and the filter canister 209, the filter canister 209 is engaged with the annular seat 208, and the replacement can be done directly. By sliding the sliding column 306, the sliding column 306 can drive the first protrusion 305 to slide, thereby separating the first protrusion 305 from the filter box 214, and then sliding the rectangular cover 301, the filter material inside the filter box 214 can be replaced.
