Description

Technical Field

[0001] This invention belongs to the field of cyclone filter technology, specifically a cyclone filter for rainwater harvesting in sponge cities. Background Technology

[0002] A sponge city refers to a city that, like a sponge, possesses excellent "elasticity" in adapting to environmental changes and responding to natural disasters. It absorbs, stores, infiltrates, and purifies rainwater when it rains, and releases and utilizes the stored water when needed. Sponge city construction follows principles such as ecological priority, combining natural methods with artificial measures to maximize the accumulation, infiltration, and purification of rainwater in urban and rural areas while ensuring drainage and flood control safety, thus promoting rainwater resource utilization and ecological environmental protection. Rainwater recycling is a crucial part of sponge city construction; removing impurities, particles, and bacteria from rainwater is key to achieving rainwater reuse. A cyclone filter is a centrifugal separation device generally used for sewage or wastewater treatment. Cyclone filters can separate solids such as sand, dirt, mud, humus, and plants from water flow. Cyclone filters used for water treatment can be used for the purification of both artificial and natural water bodies.

[0003] Existing cyclone filters contain filter screens that filter out sand, dirt, and other substances from rainwater. However, after long-term use, impurities may accumulate in the filter pores, causing blockages that are difficult for staff to detect and clean in time, thus affecting the filtration efficiency. To address this, we propose a cyclone filter for rainwater harvesting in sponge cities. Summary of the Invention

[0024] 3. In this invention, the stirring component is designed to rotate the rotating plate and the stirring plate by a motor, so that the rainwater inside the filter forms a swirling state, which increases the centrifugal force of the rainwater, helps to separate finer impurities from the rainwater, improves filtration efficiency and filtration quality, and ensures that the collected rainwater is cleaner.

[0025] 4. In this invention, the dual filtration of coarse and fine filters can effectively remove large particulate impurities, suspended solids, and some dissolved pollutants from rainwater. The coarse filter first intercepts larger particles, such as silt and leaves, while the fine filter further filters out smaller impurities and pollutants, thereby significantly improving the water purification effect.

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0038] Example 1:

[0039] Please see Figures 1-10 This application provides a cyclone filter for rainwater harvesting in sponge cities, including a support base 1, on which a filter cylinder 2 is fixedly installed. It also includes: a decontamination component disposed on the filter cylinder 2 for cleaning the fine filter screen 4 and coarse filter screen 5 inside the filter cylinder 2; a sealing component disposed on the decontamination component to simultaneously block the inlet of the filter cylinder 2 when the inside of the filter cylinder 2 is clogged; an automatic sewage discharge component disposed inside the filter cylinder 2 for automatically cleaning accumulated silt and other impurities inside the filter cylinder 2; and a stirring component disposed above the sewage discharge component to increase the centrifugal force of rainwater inside the filter cylinder 2.

[0040] A water inlet pipe 6 and a water outlet pipe 7 are connected through the filter cartridge 2. A second connecting pipe 9 and a first connecting pipe 8 are respectively connected to the bottom of the water inlet pipe 6 and the top of the water outlet pipe 7. The decontamination assembly includes a first rubber plug 10 slidably and fitted inside the first connecting pipe 8 and a second rubber plug 11 slidably and fitted inside the second connecting pipe 9. A first connecting plate 14 is slidably mounted on the first connecting pipe 8. A first spring 12 is provided between the first rubber plug 10 and the first connecting plate 14. An L-shaped second connecting plate 15 is slidably mounted on the second connecting pipe 9. A second spring 13 is provided between the second connecting plate 15 and the second rubber plug 11. One of the first connecting plates 14... A resistor plate 16 is installed at one end of the filter cylinder 2. A resistor block 17 is fixedly installed at the end of the second connecting plate 15 away from the second spring 13. The resistor block 17 is set on the resistor plate 16 and is used in conjunction with the resistor plate 16. A fine filter screen 4 and a coarse filter screen 5 are installed inside the filter cylinder 2. The radius of the filter holes of the fine filter screen 4 is smaller than the radius of the filter holes on the coarse filter screen 5. The fine filter screen 4 is located above the second carbon ring 28, and the coarse filter screen 5 is located above the fine filter screen 4. The output end of the water inlet pipe 6 is installed inside the filter cylinder 2 and is located outside the coarse filter screen 5. The output end of the water outlet pipe 7 is installed through the inside of the fine filter screen 4. The first cleaning brush 23 is located between the filter cylinder 2 and the coarse filter screen 5, and the second cleaning brush 34 is attached to the cloth. Placed on the inner wall of the fine filter screen 4, rainwater is transported from the inlet pipe 6 to the filter cylinder 2. The rainwater first enters the coarse filter screen 4 for filtration. Mud and other larger substances in the rainwater are filtered through the coarse filter screen 5 and intercepted between the filter cylinder 2 and the coarse filter screen 5. Lighter substances pass through the coarse filter screen 5 and flow downwards through the first carbon ring 3. Then, they pass through the fine filter screen 4 to filter out some of the lighter impurities in the rainwater. After two layers of filtration, the clean rainwater is finally discharged from the outlet pipe 7. Specifically, during normal water intake and discharge through the inlet pipe 6 and outlet pipe 7, due to the large water volume, the first rubber plug 10 and the second rubber plug 11 in the first connecting pipe 8 and the second connecting pipe 9 are subjected to a thrust. The first rubber plug 10 and the second rubber plug 11 respectively drive the first connecting plate 14 and the second connecting plate 15 to move normally. The first spring 12 and the second spring 13 are in a squeezed state. When the fine filter screen 4 is blocked, the water output of the water outlet pipe 7 decreases, the resistance of the first rubber plug 10 decreases, and the first spring 12 will drive the first rubber plug 10 to move. The first rubber plug 10 then drives the resistor plate 16 to slide at the bottom of the resistor block 17 through the first connecting plate 14. At this time, the first electromagnet 26 and the second electromagnet 40 receive the signal and operate, so that the second cleaning brush 34 and the first cleaning brush 23 clean the filter holes of the coarse filter screen 4 and the fine filter screen 5 respectively.When the water flow at inlet 6 decreases, the resistance of the second rubber stopper 11 decreases. The second spring 13 moves the second rubber stopper 11, and the resistor block 17 slides on top of the resistor plate 16. Following the same working principle as before, the first electromagnet 26 and the second electromagnet 40 receive signals and operate, causing the second cleaning brush 34 and the first cleaning brush 23 to clean the filter holes of the coarse filter screen 4 and the fine filter screen 5, respectively.

[0041] In this embodiment, the decontamination assembly further includes a first carbon ring 3 fixedly installed inside the filter cylinder 2. A first carbon block 22 is disposed inside the first carbon ring 3. A first cleaning brush 23 is disposed on the top of the first carbon block 22. A first sleeve 25 is slidably mounted on the top of the first cleaning brush 23. A first electromagnet 26 is disposed on the top of the first sleeve 25. A positioning cylinder 27, made of iron, is disposed below the first carbon ring 3. A second carbon ring 28 is also installed inside the filter cylinder 2. A fixing seat 29 is disposed at the center of the top of the second carbon ring 28. A second carbon block 30 is disposed inside the fixing seats 29. A positioning post is disposed on the top of the second carbon block 30. 32. A connecting frame 33 is provided on the top of the positioning column 32. A second cleaning brush 34 is fixedly installed on the outer side of the connecting frame 33, and a mounting rod 38 is provided on the top of the connecting frame 33. A second sleeve 39 is slidably installed on the top of the mounting rod 38, and a second electromagnet 40 is fixedly installed on the top of the second sleeve 39. Specifically, when the resistance plate 16 and the resistance block 17 move relative to each other, the resistance will change, and then the signal will be transmitted. This is existing technology and is only used for this purpose. The first electromagnet 26 is located at the bottom of the rotating plate 19. The outer diameter of the second electromagnet 40 is the same as the inner diameter of the positioning cylinder 27. Two first carbon blocks 22 and two carbon blocks 30 are provided. Furthermore, the two first carbon blocks 22 and the two second carbon blocks 30 are connected by electrodes. After receiving a signal, the first electromagnet 26 and the second electromagnet 40 are energized through the arrangement of the first carbon ring 3 and the first carbon block 22, and the second electromagnet 40 is energized through the arrangement of the second carbon ring 28 and the second carbon block 30. It should be noted that both the rotating plate 19 and the positioning cylinder 27 are made of iron. At this time, through magnetic attraction, the first electromagnet 26 and the second electromagnet 40 respectively drive the first sleeve 25 and the second sleeve 39 to move upward in a straight line, so that the first electromagnet 26 is magnetically attracted to the bottom of the rotating plate 19 and the second electromagnet 40 is magnetically attracted to the positioning cylinder. Inside 27, since the first sleeve 25 is located outside the first cleaning brush 23 and the second sleeve 39 is located inside the mounting rod 38, when the motor 24 drives the rotating plate 19 and the stirring plate 20 to rotate, the first cleaning brush 23 moves around the outside of the coarse filter screen 5, so that the brush surface of the first cleaning brush 23 cleans the filter holes of the filter screen 5. When the stirring plate 20 rotates, the second sleeve 39 fixed inside the positioning cylinder 27 rotates. At this time, the mounting rod 38 drives the second cleaning brush 34 installed on one side of the connecting frame 33 to move around inside the fine filter screen 4, so that the brush surface of the second cleaning brush 34 cleans the filter holes of the fine filter screen 4, thereby improving the filtration effect.

[0042] Example 2:

[0043] Based on the above embodiments, the sealing assembly includes a mounting bracket 44 detachably mounted on the second connecting plate 15. The mounting bracket 44 is provided with teeth 46, which mesh with a transmission gear 47. A rotating shaft 45 is fixedly mounted on the transmission gear 47. A baffle 43 for sealing the water inlet pipe 6 is fixedly mounted at the end of the rotating shaft 45 away from the transmission gear 47. The rotating shaft 45 and the water inlet pipe 6 are sealed and rotatably mounted. Specifically, when 4 and 5 inside 2 are blocked, 17 will slide relative to 16, that is, 15 will slide. 15 drives 44 on it to move, 14 drives 46 on it to move, and then 46 drives 47 to rotate, 47 drives 45 to rotate, and 45 drives 43 to rotate inside 6. Thus, when 4 and 5 are blocked, 6 can be sealed off to prevent rainwater from entering and prevent impurities such as mud and sand carried by rainwater from continuing to enter the interior of 2 and aggravating the problem of filter clogging.

[0044] Example 3:

[0045] Based on the above embodiments, a cover 18 is provided on the top of the filter cartridge 2;

[0046] The stirring assembly includes a motor 24 detachably mounted on the cylinder cover 18. The output end of the motor 24 extends through and to the bottom of the cylinder cover 18, where a rotating plate 19 is mounted. The bottom end of the rotating plate 19 extends through and to the bottom of the first carbon ring 3. A positioning cylinder 27 is mounted at the bottom end of the rotating plate 19. An agitating plate 20 is fixedly mounted at the bottom end of the rotating plate 19. The agitating plate 20 is located above the first carbon ring 3 and inside the coarse filter screen 5. The cylinder cover 18 has a groove 21 for engaging the coarse filter screen 5. When rainwater is delivered into the filter cylinder 2, the motor 24 is started simultaneously. The output end of the motor 24 drives the rotating plate 19 to rotate. At this time, the rotating plate 19 drives the agitating plate 20 to agitate the rainwater in the filter cylinder 2, so that the rainwater in the filter cylinder 2 is in a swirling state, generating centrifugal force, which can improve the filtration effect of the rainwater.

[0047] Example 4:

[0048] Based on the above embodiments, the automatic sewage discharge assembly includes a mounting plate 35 fixedly installed on the connecting frame 33. An airbag 36 is provided on the mounting plate 35, and a pressure sensor 37 is provided on the airbag 36. A sewage discharge pipe 41 is installed at the bottom of the filter cylinder 2, and a control valve 42 is provided on the sewage discharge pipe 41. Specifically, after the rainwater is filtered, when there is a large amount of material filtered by the fine filter screen 4, it gradually accumulates and squeezes the airbag 36 upward. Since the pressure sensor 37 is provided inside the airbag 36, which is existing technology, it is only used for this purpose. When the pressure sensor 37 senses the set pressure value, it sends a signal to the control valve 42. At this time, the control valve 42 opens, and the impurities in the filter cylinder 2 pass through the second carbon ring 28 and are discharged from the sewage discharge pipe 41. It has an automatic sewage discharge function, reduces the workload of the staff, and does not require the staff to observe and operate it.

[0049] In combination with the above four specific embodiments, this cyclone filter for rainwater harvesting in sponge cities integrates decontamination, clogging, stirring and automatic sewage discharge components, achieving efficient rainwater filtration, intelligent clogging treatment, enhanced filtration effect and convenient impurity discharge, providing comprehensive protection for the sustainable use of urban rainwater resources.

[0050] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
