Description

Technical Field

[0001] This invention relates to the technical field of urban irrigation water recycling and treatment devices, specifically an urban energy-saving greening irrigation water recycling system. Background Technology

[0002] With the acceleration of urbanization, the demand for irrigation water for greening is increasing, making urban water pollution control and treatment increasingly challenging. Traditional irrigation systems generally suffer from low water resource utilization, easy clogging of filtration structures, and high maintenance costs. If irrigation wastewater or surface runoff is discharged directly without treatment, it may carry pollutants such as soil particles, fertilizer residues, and pesticides into urban water bodies, exacerbating eutrophication and pollution, and posing a severe challenge to water pollution control and treatment.

[0003] In existing technologies, circulating water filtration systems mostly employ single-layer fixed filter screens or simple stacked designs. Accumulation of impurities on the filter screen surface necessitates manual cleaning after system shutdown, resulting in low efficiency. Some automatic cleaning solutions suffer from complex structures, incomplete cleaning, or excessive energy consumption. Therefore, there is an urgent need for a greening irrigation water circulation system that can achieve efficient self-cleaning, staged filtration, and energy-saving and environmentally friendly practices. This system should effectively remove suspended pollutants from the recycled water, ensure circulating water quality, and improve the effectiveness of water pollution control. Summary of the Invention

[0004] To address the above problems, this invention provides an urban energy-saving greening irrigation water recycling system.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an urban energy-saving greening irrigation water circulation system, including a circulating water tank, an inlet pipe provided on the upper side of the circulating water tank, and a first filter component and a second filter component coaxially arranged inside the circulating water tank, with the first filter component located inside the second filter component; The first filter assembly includes two C-shaped filter screens arranged in a staggered manner. One end of each C-shaped filter screen is connected to a suction plate and a cleaning scraper. The suction port of the suction plate faces the inside of the other C-shaped filter screen. The cleaning scraper is connected to the front end of the suction plate and contacts and abuts against the inside of the other C-shaped filter screen. The water inlet pipe is equipped with a drive assembly. The drive assembly is detachably connected to the C-shaped filter screen. After the drive assembly is connected to the C-shaped filter screen, it drives the C-shaped filter screen to rotate, so that the cleaning scraper and the suction assembly clean the other C-shaped filter screen. The second filter assembly includes a filter cylinder.

[0006] As an optimization, the water inlet pipe includes a fixed section and a connecting section, the connecting section is rotatably connected to the lower end of the fixed section, the drive assembly is connected to the connecting section, and the fixed section is connected to a dosing pipe; The driving assembly includes a drive motor, a first suction tube, a second suction tube, and a limiting telescopic rod. The drive motor is fixedly connected to the connecting section. The first suction tube is connected to the output shaft of the drive motor. The second suction tube is horizontally and detachably connected to the lower part of the first suction tube. A first connection port is provided on the lower side of the outer end of the second suction tube. The limiting telescopic rod is connected to the outer end of the second suction tube. A second connection port is provided on the upper end of the suction plate. When the first connection port and the second connection port are connected relative to each other, the limiting telescopic rod extends into the suction plate, so that the second suction tube is connected to the suction plate.

[0007] As an optimization, a connecting magnet is provided at the end of the C-shaped filter away from the suction plate. The connecting magnet is used to magnetically attract another C-shaped filter, so that the two C-shaped filters are tightly attached to each other.

[0008] As an optimization, the bottom of the C-shaped filter screen contacts the bottom of the circulating water tank, and the bottom of the filter cylinder is rotatably connected to the bottom surface of the circulating water tank.

[0009] As an optimization, the upper part of the first suction tube is provided with a connecting slip ring, the lower part of the first suction tube is provided with a through hole, the second suction tube is sleeved on the outside of the first suction tube, and the second suction tube is provided with a locking bolt.

[0010] As an optimization, a connecting rod is provided between the suction plate and the cleaning scraper. The connecting rod is an elastic rod, which gives the cleaning scraper a tendency to press outward.

[0011] As an optimization, the tip of the cleaning scraper rotates toward the rotation direction of the C-shaped filter, and the central angle of the C-shaped filter is greater than 180°.

[0012] As an optimization, a drain pipe is provided on the outside of the circulating water tank, and a sewage pipe is provided at the bottom of the circulating water tank in the axial direction.

[0013] As an optimization, the second suction tube is connected to several stirring plates, the lower ends of which extend into the lower inner part of the first filter assembly.

[0014] The beneficial effects of this plan are as follows: With the staggered C-type filters working in conjunction with the cleaning scraper and suction components, impurities on the filters can be automatically scraped off and sucked up during operation. The two C-type filters clean each other, which can effectively prevent clogging and significantly reduce the frequency of manual maintenance. It adopts a dual structure of coaxial first filter component (C-type filter screen) and second filter component (filter cartridge) to achieve the synergistic effect of coarse filtration and fine filtration, thereby improving the water purification effect; The second suction pipe is equipped with a stirring plate, which can efficiently stir the flocculant and wastewater, thereby improving the wastewater treatment efficiency. At the same time, the second suction pipe can be connected to the first filter assembly to drive the first filter assembly to operate. Attached Figure Description

[0026] like Figures 1-8 As shown, an urban energy-saving greening irrigation water recycling system includes a circulating water tank 1, an inlet pipe 2 is provided on the upper side of the circulating water tank 1, and a first filter component and a second filter component are coaxially arranged inside the circulating water tank 1, with the first filter component located inside the second filter component. The first filter assembly includes two C-shaped filter screens 3 arranged in a staggered manner. One end of each C-shaped filter screen 3 is connected to a suction plate 4 and a cleaning scraper 5. The suction port of the suction plate 4 faces the inside of the other C-shaped filter screen 3. The cleaning scraper 5 is connected to the front end of the suction plate 4 and contacts and abuts against the inside of the other C-shaped filter screen 3. The water inlet pipe 2 is equipped with a drive assembly. The drive assembly is detachably connected to the C-shaped filter screen 3. After the drive assembly is connected to the C-shaped filter screen 3, it drives the C-shaped filter screen 3 to rotate, so that the cleaning scraper 5 and the suction assembly clean the other C-shaped filter screen 3. The second filter assembly includes a filter cylinder 6.

[0027] Irrigation return water is discharged into the circulating water tank 1 through the inlet pipe 2, filtered by the first filter component and then by the second filter component. It can be discharged only after two filtrations.

[0028] Two C-shaped filters 3 are connected in an alternating manner, and the cleaning scraper 5 is attached to the inner side of another C-shaped filter 3.

[0029] like Figure 1 As shown, the water inlet pipe 2 includes a fixed section and a connecting section. The connecting section is rotatably connected to the lower end of the fixed section. The drive assembly is connected to the connecting section. The fixed section is connected to a dosing pipe. The driving assembly includes a drive motor 7, a first suction tube 8, a second suction tube 9, and a limiting telescopic rod 10. The drive motor 7 is fixedly connected to the connecting section. The first suction tube 8 is connected to the output shaft of the drive motor 7. The second suction tube 9 is horizontally and detachably connected to the lower part of the first suction tube 8. A first connection port is provided on the lower side of the outer end of the second suction tube 9. The limiting telescopic rod 10 is connected to the outer end of the second suction tube 9. A second connection port is provided on the upper end of the suction plate 4. When the first connection port and the second connection port are connected relative to each other, the limiting telescopic rod 10 extends into the suction plate 4, so that the second suction tube 9 is connected to the suction plate 4.

[0030] The connecting section is L-shaped, with the vertical section facing the opening of the circulating water tank 1. The connecting section can rotate around the fixed section. The dosing pipe can be equipped with a solenoid valve or a dosing pump to control the dosing amount or dosing time. Flocculants, chemical treatment agents, adsorbents, etc., can be added to the wastewater through the dosing pipe.

[0031] The second suction tube 9 can move along the first suction tube 8. When the second suction tube 9 is connected to the first suction tube 8, it can provide negative pressure to the suction plate 4 through the drive component.

[0032] When the first connection port and the second connection port are set opposite to each other, the two are limited and connected by the limiting telescopic rod 10.

[0033] like Figure 5 As shown, a connecting magnet 11 is provided at the end of the C-type filter 3 away from the suction plate 4. The connecting magnet 11 is used to magnetically attract another C-type filter 3, so that the two C-type filters 3 are tightly attached to each other.

[0034] The C-type filter 3 is magnetically attracted by the connecting magnet 11. When the connecting magnet 11 is separated from the C-type filter 3, the end of the C-type filter 3 with the connecting magnet 11 will spring outward, allowing the scraper of the other C-type filter 3 to continue rotating and enter the inner side of the C-type filter 3, thus achieving the staggered connection between the two.

[0035] like Figure 8 As shown, the bottom of the C-shaped filter screen 3 is in contact with the bottom of the circulating water tank 1, and the bottom of the filter cylinder 6 is rotatably connected to the bottom surface of the circulating water tank 1.

[0036] like Figure 8 As shown, the upper part of the first suction tube 8 is provided with a connecting slip ring 12, the lower part of the first suction tube 8 is provided with a through hole, the second suction tube 9 is sleeved on the outside of the first suction tube 8, and the second suction tube 9 is provided with a locking bolt.

[0037] The suction pump is connected via the slip ring 12 to provide negative pressure to the suction plate 4. Tightening the locking bolts will lock the second suction pipe 9 and the first suction pipe 8.

[0038] like Figure 7 As shown, a connecting rod 13 is provided between the suction plate 4 and the cleaning scraper 5. The connecting rod 13 is an elastic rod, which makes the cleaning scraper 5 have a tendency to press outward.

[0039] like Figure 5 As shown, the tip of the cleaning scraper 5 rotates in the direction of rotation of the C-type filter 3, and the central angle of the C-type filter 3 is greater than 180°.

[0040] like Figure 8 As shown, a drain pipe 14 is provided on the outside of the circulating water tank 1, and a sewage pipe 15 is provided at the bottom of the circulating water tank 1 in the axial direction.

[0041] like Figure 2 As shown, the second suction tube is connected to several stirring plates, the lower ends of which extend into the lower inner part of the first filter assembly.

[0042] The mixing plate can be linear or fan-shaped. The mixing plate can move along with the second suction pipe to stir the sewage and promote efficient mixing of sewage and flocculant.

[0043] How to use: When the device is in use, the irrigation return water enters the circulating water tank 1 through the inlet pipe 2. The water flow first impacts the C-type filter screen 3 (central angle > 180°) of the first filter component. Large particles of impurities are intercepted inside the C-type filter screen 3. The water that has been initially filtered passes through the C-type filter screen 3 and enters the filter cylinder 6 area of ​​the second filter component. The drive motor 7 drives the second suction tube 9 to rotate via the first suction tube 8. After the limiting telescopic rod 10 connects with the second connection port of the suction plate 4, the drive assembly and the C-type filter screen 3 are linked. During the rotation of the two staggered C-type filter screens 3, the relative positions are kept stable by the connecting magnet 11. The cleaning scraper 5 continuously presses the inner wall of the adjacent C-type filter screen 3 under the action of the elastic connecting rod 13.

[0044] like Figure 4 As shown, in the initial state, the two C-type filters 3 are staggered, with the left C-type filter 3 being filter A and the right C-type filter 3 being filter B. When the drive is connected to filter A, the drive assembly drives filter A to rotate clockwise, and the cleaning scraper 5 cleans the inner surface of filter B clockwise, while the suction plate 4 simultaneously suctions. When filter A rotates about 180°, the cleaning of filter B is completed. Continue to rotate filter A so that the cleaning scraper 5 of filter A rotates back into the inside of filter B. At this time, the connecting magnet 11 of filter A is located inside filter B. Continue to rotate filter A so that the connecting magnet 11 of filter A separates from filter B and pops outward. Then rotate filter A in the opposite direction, so that the connecting magnet 11 of filter A rotates to the outside of filter B, and the cleaning scraper 5 of filter B contacts the inside of filter A, returning to the initial state.

[0045] During the rotation process, the cleaning scraper 5 scrapes off the impurities attached to the C-type filter screen 3. The scraped-off impurities are discharged into the drain pipe 15 through the second suction pipe 9 and the first suction pipe 8 (through the through hole) under the negative pressure of the suction plate 4, thus avoiding secondary pollution.

[0046] Water filtered by C-type filter screen 3 undergoes secondary fine filtration through filter cylinder 6. The purified water flows back to the irrigation system through drain pipe 14, and sediment is periodically discharged through sewage pipe 15.

[0047] After loosening the locking bolt, the second suction tube 9 can slide off along the first suction tube 8. The retraction of the limiting telescopic rod 10 can separate the drive assembly from the C-type filter screen 3, making it easy to replace the damaged cleaning scraper 5 or filter screen.

[0048] The connecting magnet 11 forms a sealed connection at the joint of the C-type filter screen 3, preventing leakage of unfiltered water and reducing drive energy consumption.

[0049] The elastic properties of the connecting rod 13 can compensate for the deformation of the C-type filter screen 3 after long-term use, ensuring that the cleaning scraper 5 always effectively adheres to the surface of the filter screen.

[0050] The bottom of the C-type filter screen 3 is attached to the bottom surface of the circulating water tank 1, and the filter cylinder 6 is coaxially sleeved on the outside, maximizing the use of the longitudinal space of the water tank and making it suitable for installation in small urban green areas.
