Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically a water purification device for sewage outlets into rivers. Background Technology

[0002] With the rapid development of industrialization and urbanization, sewage outlets into rivers serve as key channels for land-based pollutants to enter river water bodies. The sewage discharged from these outlets often contains a large amount of suspended solids, impurities, heavy metals, and organic compounds, directly leading to serious water pollution problems, disrupting the ecological balance of rivers, and affecting water resource utilization and the quality of the living environment. Currently, water purification devices for sewage outlets into rivers have been applied to some extent, but existing devices still have many shortcomings and are difficult to meet actual purification needs.

[0003] The existing filtration systems lack efficient circulation filtration mechanisms, resulting in incomplete wastewater filtration and limited removal of pollutants such as heavy metals and organic compounds, making it difficult to achieve discharge standards. Some filtration components are prone to accumulating impurities and lack effective self-cleaning functions, leading to a significant decrease in filtration efficiency after long-term use, which cannot continuously alleviate water pollution problems. In addition, the operation and maintenance of existing devices are complex, and the removal of impurities is inconvenient, making it difficult to meet the requirements of long-term stable operation of sewage outlets into rivers. Therefore, the development of a fixed, reliable, well-sealed, energy-efficient, thoroughly filtered, and easy-to-maintain water purification device for sewage outlets into rivers has become an urgent need to solve current water pollution problems and improve the quality of water entering rivers. Summary of the Invention

[0010] Preferably, the primary filtration device includes a filter cylinder, the upper end of which is fixedly connected to the lower end of the guide pipe. A mounting frame is provided at the lower end of the filter cylinder, and the lower end of the mounting frame is fixedly connected to the bottom wall of the inner cavity of the outer shell.

A cleaning mechanism is provided in the middle of the inner cavities of the filter cylinder and the mounting frame. A limit mechanism is provided at the lower end of the cleaning mechanism. The inner cavity of the guide pipe is not connected to the inner cavity of the cleaning mechanism through a guide plate, but only to the inner cavity of the filter cylinder.

[0011] Preferably, the cleaning mechanism includes a mounting cylinder, which is rotatably mounted on the lower end of the guide plate. The inner surface of the mounting cylinder is fixedly connected to the outer surface of the transmission handle.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a stable connection with the sewage pipe is achieved through the sealing element and fixing mechanism in the water inlet device. The sealing element is equipped with multiple rubber sealing rings of different diameters, which can be adapted to sewage pipes of different sizes to ensure sealing performance and prevent sewage leakage. The fixing mechanism uses toothed rings to link multiple fixing elements to move synchronously, so as to achieve uniform clamping of the sewage pipe. The fixing operation is convenient and reliable, avoiding device displacement or sewage leakage caused by insecure fixing, and reducing the risk of water pollution.

[0015] 2. In this invention, the cleaning mechanism in the water inlet device intercepts larger-volume garbage in the sewage through a blocking net. With the rotation of the guide fan, the intercepted garbage can be thrown into the collection box for centralized collection in a timely manner. At the same time, the guide fan can clean the blocking net during rotation to prevent garbage from adhering and clogging. The collection box is detachable for easy garbage cleaning. Moreover, the sewage in the collection box can be returned to the water inlet pipe through the connecting pipe to realize sewage recycling treatment, avoid water waste, and prevent garbage from entering the device and affecting its operation.

[0016] 3. In this invention, an auxiliary power mechanism is provided. When the sewage volume is large and the flow rate is fast, the water flow impacts the guide plate, causing the fixed ring and the transmission handle to rotate. The auxiliary motor drives the transmission handle to run, which effectively saves motor power consumption and reduces operating energy consumption. The combination of motor drive and water flow auxiliary power ensures that the device can operate stably under different sewage flow rates, improving the economic efficiency and reliability of operation.

[0017] 4. In this invention, a filtration structure combining a primary filtration device and a secondary filtration device is adopted. The primary filtration device achieves preliminary filtration of sewage through a filter cylinder, while the secondary filtration device uses activated carbon and other filter media to deeply adsorb and filter pollutants such as heavy metals and organic compounds, ensuring that the effluent meets standards. Simultaneously, the primary filtration device is equipped with a cleaning mechanism and a limiting mechanism. When the drive handle rotates, it drives multiple guide frame plates to rotate synchronously through the second mounting cylinder. The thrust generated during the rotation of the guide frame plates guides the sewage in the gap between the filter cylinder and the first mounting cylinder through the inlet hole to the lower part of the inner cavity of the mounting frame. During this process, the guide frame plates guide some sewage to the inner cavity of the second mounting cylinder. Subsequently, the guide arc plate pushes the sewage in the inner cavity of the second mounting cylinder upwards. During the sewage flow, impurities contained therein are intercepted by the filter plates on the outer surface of the arc-shaped frame plate and remain in the lower part of the inner cavity of the cleaning arc plate. The filtered sewage enters the inner cavity of the first mounting cylinder under the guidance of the arc-shaped frame plate, achieving separation of impurities and sewage and circulating filtration of sewage, significantly improving filtration efficiency and impurity removal effect, effectively reducing the concentration of pollutants entering the river, and improving river water quality.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, as Figure 1 - Figure 18 As shown, this embodiment discloses a water purification device for a sewage outlet into a river, including a shell 1. A water inlet device 2 is provided on the upper part of the outer surface of the shell 1, a water outlet pipe 5 is provided on the lower part of the outer surface of the shell 1, a sludge discharge pipe 6 is provided at the lower end of the shell 1, a motor 3 is provided at the upper end of the shell 1, a transmission handle 7 is provided at the output end of the motor 3, the lower end of the transmission handle 7 extends to the lower part of the inner cavity of the shell 1, an auxiliary power mechanism 4 is provided on the upper part of the inner cavity of the shell 1, a primary filter device 8 is provided at the lower end of the auxiliary power mechanism 4, a secondary filter device 9 is provided on the lower part of the outer surface of the primary filter device 8, and the outer surface of the secondary filter device 9 is fixedly connected to the lower part of the inner cavity of the shell 1.

[0022] Specifically, before using the purification device, the staff inserts the drain pipe into the inner cavity of the water inlet device 2 to achieve a fixed connection between the purification device and the drain pipe, while ensuring the sealing performance between the water inlet device 2 and the drain pipe. Then the drain pipe discharges sewage. When the sewage flows through the water inlet device 2, the water inlet device 2 can intercept and remove larger volume garbage contained in the sewage. The treated sewage enters the upper part of the inner cavity of the outer shell 1.

[0023] Furthermore, after the sewage enters the upper part of the inner cavity of the outer shell 1, it flows through the auxiliary power mechanism 4 and the primary filter device 8 in sequence. After the primary filter device 8 performs preliminary filtration, it enters the secondary filter device 9 for secondary deep filtration. The filtered water is discharged into the river through the outlet pipe 5.

[0024] Furthermore, when sewage enters the upper part of the inner cavity of the outer shell 1 through the inlet device 2, if the sewage volume is large and the flow rate is fast, the sewage can drive the auxiliary power mechanism 4 to rotate synchronously, and then drive the transmission handle 7 to rotate through the auxiliary power mechanism 4, effectively saving the power required for the motor 3 to drive the transmission handle 7 to rotate; if the sewage volume entering the inner cavity of the outer shell 1 is small and the flow rate is slow, the motor 3 will start and drive the transmission handle 7 to rotate, ensuring the normal operation of each mechanism of the device.

[0025] Furthermore, the secondary filtration device 9 is composed of filter media such as activated carbon, zeolite, and quartz sand mixed in a specific ratio. Activated carbon, with its ultra-large specific surface area and strong adsorption performance, can efficiently adsorb recalcitrant organic compounds, odor substances, and some dissolved pollutants in wastewater. Zeolite has excellent ion exchange capacity and can specifically adsorb heavy metal ions such as lead, cadmium, and mercury in wastewater, while also assisting in the removal of some ammonia nitrogen pollutants. Quartz sand can further intercept the tiny suspended solids remaining in the wastewater after primary filtration, improving filtration accuracy. The synergistic effect of multiple filter media enables the secondary filtration device 9 to efficiently and deeply filter pollutants such as heavy metals and some organic compounds in wastewater, effectively reducing pollutant content and ensuring that the effluent water quality meets standards. This is existing technology and will not be described in detail in this manual.

[0026] To ensure a secure fixation between the purification device and the sewage pipe, such as Figure 4 and Figure 5As shown, the water inlet device 2 includes a water inlet pipe 21, which is fixedly installed on the upper part of the outer surface of the housing 1, and the inner cavity of the water inlet pipe 21 is connected to the inner cavity of the housing 1. A sealing element 22 is provided at one end of the water inlet pipe 21, and a fixing mechanism 23 is provided at one end of the sealing element 22. A guide frame 24 is provided on the upper side of the middle part of the outer surface of the water inlet pipe 21, and a collection box 25 is provided on the upper part of the outer surface of the guide frame 24. A connecting pipe 26 is provided at the lower end of the collection box 25. The inner cavities of the guide frame 24 and the connecting pipe 26 are connected to the inner cavity of the water inlet pipe 21. A cleaning mechanism 27 is provided on the side of the inner cavity of the water inlet pipe 21 away from the sealing element 22.

[0027] Specifically, after the staff inserts the drain pipe into the inner cavity of the water inlet device 2, the end face and outer surface of the drain pipe are tightly fitted with the inner surface of the sealing element 22, so as to achieve a sealing fit between the drain pipe and the sealing element 22. Then, the staff rotates the fixing mechanism 23 to clamp and fix the drain pipe, thereby completing the fixed installation of the purification device and the drain pipe.

[0028] Furthermore, after the sewage pipe leads the sewage into the inner cavity of the inlet pipe 21, the larger volume garbage contained in the sewage is guided into the inner cavity of the guide frame 24 by the action of the cleaning mechanism 27, and then falls into the collection box 25 for collection. During this process, a small amount of sewage will enter the inner cavity of the collection box 25 along with the garbage. The sewage in the inner cavity of the collection box 25 can flow back to the inner cavity of the inlet pipe 21 through the connecting pipe 26 to realize the recycling treatment of sewage and avoid waste of water resources.

[0029] Furthermore, when a large flow of sewage enters the inner cavity of the inlet pipe 21, some sewage may overflow into the inner cavity of the collection tank 25 through the connecting pipe 26. After the sewage flow decreases, the sewage stored in the inner cavity of the collection tank 25 will automatically flow back into the inner cavity of the inlet pipe 21 to ensure the continuity of the device operation.

[0030] To ensure the sealing effect between the seal 22 and the drain pipe, such as Figure 6 As shown, the sealing element 22 includes a support ring 221, which is fixedly installed on the end face of the water inlet pipe 21. Multiple rubber sealing rings 222 are provided in the middle of the inner cavity of the support ring 221, and the diameters of the multiple rubber sealing rings 222 decrease sequentially.

[0031] Specifically, when the sewage pipe is inserted into the inner cavity of the support ring 221, since the inner cavity of the support ring 221 is provided with multiple rubber sealing rings 222 of different diameters, the sewage pipe will be in close contact with the surface of the rubber sealing ring 222 that is matched with the size, and the end face of the sewage pipe will be in contact with the base surface of the corresponding rubber sealing ring 222. After the fixing mechanism 23 completes the fixing of the sewage pipe, the sealing element 22 and the surface of the sewage pipe form a reliable seal, effectively preventing sewage leakage.

[0032] To ensure a secure fixation between the purification device and the sewage pipe, such as Figure 6 As shown, the fixing mechanism 23 includes an annular plate 231, which is fixedly installed on the end face of the support ring 221. A plurality of fixing members 232 are provided at the end of the annular plate 231 away from the support ring 221. A toothed ring 233 is rotatably installed on the middle of the outer surface of the plurality of fixing members 232, and the toothed ring 233 is engaged with the plurality of fixing members 232.

[0033] Furthermore, such as Figure 7 As shown, the fixing member 232 includes a support frame 2321, which is fixedly installed on the end face of the annular plate 231. The middle of the outer surface of the support frame 2321 is rotatably connected to the inner surface of the toothed ring 233. A threaded rod 2322 is threadedly connected to the middle of the upper side of the support frame 2321. A rubber sheet 2323 is provided at the end of the threaded rod 2322 away from the toothed ring 233. A transmission rod 2324 is slidably installed in the middle of the threaded rod 2322. A gear 2325 is provided at the end of the transmission rod 2324 away from the rubber sheet 2323. The gear 2325 meshes with the toothed ring 233.

[0034] Specifically, after the sewage pipe is inserted into the inner cavity of the seal 22 and reaches the designated position, the operator rotates the gear ring 233. When the gear ring 233 rotates, it drives the gear 2325 that meshes with it to rotate synchronously. The gear 2325 drives the threaded rod 2322 to move axially along the threaded hole of the support frame 2321 through the transmission rod 2324, thereby pushing the rubber sheet 2323 to move closer to the sewage pipe. When the rubber sheet 2323 is tightly attached to the outer surface of the sewage pipe and forms a clamping force, the fixing operation between the purification device and the sewage pipe is completed. The fixing is reliable and the operation is convenient.

[0035] To promptly remove larger volumes of waste from the wastewater and prevent them from entering the inner cavity of the outer casing 1, thus avoiding blockages and disruptions to the normal operation of the device, such as... Figure 8 As shown, the cleaning mechanism 27 includes a barrier net 271, which is fixedly installed on the inner surface of the water inlet pipe 21. One end face of the barrier net 271 is flush with the inner surface of the guide frame 24. A drive shaft 272 is rotatably mounted in the middle of the barrier net 271. A guide fan 273 is provided on the outer surface of the drive shaft 272 near the guide frame 24, and a transmission component 274 is provided on the outer surface of the drive shaft 272 away from the guide frame 24. The transmission component 274 drives the transmission handle 7 and the drive shaft 272.

[0036] Specifically, when sewage enters the inner cavity of the inlet pipe 21, the baffle 271 intercepts larger pieces of waste in the sewage to prevent them from entering the subsequent treatment unit. Then, the motor 3 drives the transmission component 274 to rotate through the transmission handle 7. The transmission component 274 drives the guide fan 273 to rotate synchronously through the transmission shaft 272. The centrifugal force generated during the rotation of the guide fan 273 throws the larger pieces of waste intercepted by the baffle 271 into the inner cavity of the guide frame 24, and then into the collection box 25 for centralized collection. After the purification device has been working continuously for a period of time, the staff can disassemble and remove the collection box 25 to clean the larger pieces of waste collected in its inner cavity, ensuring the smooth operation of the device.

[0037] Furthermore, during the rotation of the guide fan 273, its blades can simultaneously clean the outer surface of the barrier net 271, effectively preventing large debris from adhering to the surface of the barrier net 271 and causing blockage, thus ensuring smooth sewage flow.

[0038] To assist motor 3 in driving transmission handle 7 to rotate, thereby reducing motor energy consumption and improving device operating efficiency, such as Figure 9 and Figure 10 As shown, the auxiliary power mechanism 4 includes a guide pipe 41, which is fixedly installed in the upper part of the inner cavity of the housing 1. A fixing ring 42 is rotatably installed on the outer surface of the guide pipe 41. The inner surface of the fixing ring 42 is fixedly connected to the outer surface of the transmission handle 7. A plurality of guide plates 43 are provided on the outer surface of the fixing ring 42. A guide plate 44 is provided in the lower part of the inner cavity of the guide pipe 41.

[0039] Specifically, when sewage enters the inner cavity of the outer shell 1 through the inlet device 2, the water flow impacts multiple guide plates 43, causing the fixed ring 42 to rotate around the axis of the guide pipe 41. When the fixed ring 42 rotates, it drives the transmission handle 7, which is fixedly connected to it, to rotate synchronously, thereby assisting the motor 3 in driving the transmission handle 7 to rotate, effectively reducing the power consumption of the motor 3 and achieving energy-saving operation.

[0040] Furthermore, after the sewage comes into contact with the guide plate 43, it flows along the middle of the fixed ring 42 to the guide plate 44. Under the guidance of the guide plate 44, the sewage smoothly enters the inner cavity of the primary filtration device 8, ensuring a stable and orderly filtration process.

[0041] Example 2: This example further improves upon Example 1 by modifying the primary filtration device 8 to enhance the initial filtration effect of wastewater, such as... Figure 11 — Figure 13As shown, the primary filtration device 8 includes a filter cylinder 81. The upper end of the filter cylinder 81 is fixedly connected to the lower end of the guide pipe 41. A mounting frame 82 is provided at the lower end of the filter cylinder 81. The lower end of the mounting frame 82 is fixedly connected to the bottom wall of the inner cavity of the outer shell 1. The inner cavity of the mounting frame 82 communicates with the inner cavity of the sludge discharge pipe 6. A cleaning mechanism 83 is provided in the middle of the inner cavities of the filter cylinder 81 and the mounting frame 82. A limit mechanism 84 is provided at the lower end of the cleaning mechanism 83. The inner cavity of the guide pipe 41 is not connected to the inner cavity of the cleaning mechanism 83 through the guide plate 44, but is connected to the inner cavity of the filter cylinder 81.

[0042] Specifically, under the guidance of the guide plate 44, the sewage enters the gap between the filter cylinder 81 and the cleaning mechanism 83. After being filtered by the filter cylinder 81, it enters the lower part of the inner cavity of the outer shell 1. The sewage entering the lower part of the inner cavity of the outer shell 1 further flows through the secondary filtration device 9. The secondary filtration device 9 performs deep treatment on the pollutants such as heavy metals and some organic compounds in the sewage that were not removed by the primary filtration device 8, ensuring that the effluent meets the standards.

[0043] Furthermore, when the transmission handle 7 rotates, it synchronously drives the cleaning mechanism 83 to rotate. During the rotation of the cleaning mechanism 83, the inner surface of the filter cylinder 81 is cleaned to prevent impurities from adhering and clogging the filter cylinder 81, thus ensuring filtration efficiency. At the same time, the impurities intercepted by the filter cylinder 81 accumulate in the gap between the filter cylinder 81 and the cleaning mechanism 83. When the transmission handle 7 drives the cleaning mechanism 83 to rotate, it synchronously drives the limiting mechanism 84 to rotate.

[0044] Furthermore, during the rotation of the limiting mechanism 84, the sewage in the gap is pushed downwards, causing the sewage to carry impurities into the lower part of the inner cavity of the mounting frame 82. At the same time, the limiting mechanism 84 guides the sewage in the lower part of the inner cavity of the mounting frame 82 to the inner cavity of the cleaning mechanism 83. During this process, the limiting mechanism 84 intercepts the impurities to prevent them from entering the inner cavity of the cleaning mechanism 83. Subsequently, the sewage in the inner cavity of the cleaning mechanism 83 re-enters the inner cavity of the filter cartridge 81 for secondary filtration. The intercepted impurities gradually accumulate in the lower part of the inner cavity of the mounting frame 82. After the purification device has been used for a period of time, the staff can open the sludge discharge pipe 6 to discharge the impurities accumulated in the inner cavity of the mounting frame 82, ensuring the long-term stable operation of the device.

[0045] To effectively clean the inner surface of the filter cartridge 81 and prevent impurities from adhering and clogging it, such as Figure 14As shown, the cleaning mechanism 83 includes a mounting cylinder 831, which is rotatably mounted on the lower end of the guide plate 44. The inner surface of the mounting cylinder 831 is fixedly connected to the outer surface of the transmission handle 7. The outer surface of the mounting cylinder 831 is provided with multiple cleaning arc plates 832, which are adapted to the filter cylinder 81. Multiple elongated filter screens 833 are provided on the upper part of the outer surface of the cleaning arc plates 832, and the multiple elongated filter screens 833 and the multiple cleaning arc plates 832 are distributed at intervals. A mounting ring 834 is rotatably mounted on the lower part of the outer surface of the mounting cylinder 831. The mounting ring 834 is fixedly mounted on the inner surface of the mounting frame 82, and a water inlet hole 835 is provided at the upper end of the mounting ring 834.

[0046] Specifically, when the drive handle 7 drives the mounting cylinder 831 to rotate, the mounting cylinder 831 simultaneously drives multiple cleaning arc plates 832 to rotate. The outer surface of the cleaning arc plates 832 is in close contact with the inner surface of the filter cylinder 81, which thoroughly cleans the impurities attached to the inner surface of the filter cylinder 81, effectively preventing the filter cylinder 81 from clogging and ensuring stable filtration efficiency.

[0047] Furthermore, after the sewage enters the auxiliary power mechanism 4, it is guided by the guide plate 44 into the gap between the filter cylinder 81 and the mounting cylinder 831. When the limiting mechanism 84 rotates, the sewage in the gap is guided into the lower part of the inner cavity of the mounting frame 82 through the water inlet hole 835 on the mounting ring 834. At the same time, the limiting mechanism 84 guides the sewage in the lower part of the inner cavity of the mounting frame 82 into the inner cavity of the mounting cylinder 831. The sewage in the inner cavity of the mounting cylinder 831 re-enters the gap between the filter cylinder 81 and the mounting cylinder 831 through the long strip filter screen 833, realizing the circulation filtration of sewage and improving the filtration effect.

[0048] Furthermore, the elongated filter screen 833 is used to intercept impurities in the gap between the filter cylinder 81 and the mounting cylinder 831, preventing impurities from entering the inner cavity of the mounting cylinder 831, avoiding blockage of the inner cavity of the mounting cylinder 831, and ensuring the normal operation of the device.

[0049] To achieve the guided circulation of wastewater and the interception and separation of impurities, such as Figure 15 and Figure 16 As shown, the limiting mechanism 84 includes a second mounting cylinder 841, which is rotatably mounted on the inner surface of the first mounting cylinder 831. The inner wall of the middle part of the second mounting cylinder 841 is fixedly connected to the outer surface of the transmission handle 7. A plurality of guide frames 842 are provided on the outer surface of the second mounting cylinder 841. The inner cavities of the plurality of guide frames 842 are connected to the inner cavity of the second mounting cylinder 841. A plurality of pushers 843 are provided on the outer side of the upper end of the second mounting cylinder 841.

[0050] Furthermore, such as Figure 17 and Figure 18As shown, the pusher 843 includes an arc-shaped frame plate 8431, which is fixedly installed on the upper end of the mounting cylinder 841. The inner cavity of the arc-shaped frame plate 8431 is connected to the inner cavity of the mounting cylinder 841. A filter plate 8432 is provided on the outer surface of the arc-shaped frame plate 8431, and a guide arc plate 8433 is provided at the lower end of the arc-shaped frame plate 8431.

[0051] Specifically, when the transmission handle 7 rotates, it drives multiple guide frame plates 842 to rotate synchronously through the second mounting cylinder 841. The thrust generated during the rotation of the guide frame plates 842 guides the sewage in the gap between the filter cylinder 81 and the first mounting cylinder 831 through the water inlet 835 to the lower part of the inner cavity of the mounting frame 82. During this process, the guide frame plates 842 guide part of the sewage to the inner cavity of the second mounting cylinder 841. Then, the guide arc plate 8433 pushes the sewage in the inner cavity of the second mounting cylinder 841 upward. During the sewage flow, the impurities contained therein are intercepted by the filter plate 8432 on the outer surface of the arc frame plate 8431 and remain in the lower part of the inner cavity of the cleaning arc plate 832. The filtered sewage enters the inner cavity of the first mounting cylinder 831 under the guidance of the arc frame plate 8431, realizing the separation of impurities and sewage and the circulation filtration of sewage.
