Description

Technical Field

[0001] The present invention relates to the technical field of urban sewage treatment, and in particular to a high-efficiency reaction filter for recycling urban sewage and using it in a green and low-carbon drainage system. Background Art

[0002] Urban sewage treatment is an important issue in today's environmental protection. The green and low-carbon drainage system is a drainage system design concept that reduces environmental impact and carbon emissions. It combines the principles of sustainable development and emphasizes the effective management and protection of water resources. Traditional urban sewage drainage systems generally filter and remove large solid waste in urban sewage and then discharge it directly. Smaller solids in urban sewage will be discharged along with the sewage, and urban sewage cannot be recycled. In order to achieve a green and low-carbon drainage system, it is necessary to treat and sterilize smaller solids in urban sewage through high-efficiency reaction filters so that urban sewage can be recycled.

[0003] However, in the process of multiple filtration treatment of urban sewage by high-efficiency reaction filters in the prior art, smaller solids in the urban sewage will accumulate and clog the mesh of the filter screen. The clogged solids will make it impossible for the urban sewage to pass through the filter screen. Generally, it is necessary to replace the filter screen regularly to maintain the filtration treatment effect of the urban sewage. However, frequent replacement of the filter screen will increase the cost. When replacing the filter screen, the machine needs to be shut down for replacement, which increases the downtime and time cost, and the efficiency of urban sewage treatment is also reduced. Therefore, it is necessary to improve the filtration effect of the high-efficiency reaction filter on urban sewage without replacing the filter screen.

[0033] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figures 1 to 9 As shown, the present invention provides an embodiment: a high-efficiency reaction filter for recycling urban sewage for a green and low-carbon drainage system, comprising a support leg 1, a filter cartridge 2, and a sealing cover 3. The filter cartridge 2 is fixedly connected to the support leg 1, and the sealing cover 3 is detachably mounted on the top of the filter cartridge 2. The top of the sealing cover 3 is fixedly connected to a sewage inlet pipe 4, and the interior of the filter cartridge 2 is fixedly connected to a drainage inclined plate 8. The interior of the filter cartridge 2 is provided with an anti-blocking and impurity removal component for preventing impurities in the sewage from clogging while quickly removing the impurities to improve the sewage filtration effect. The anti-blocking and impurity removal component is provided with a flushing component for reversely flushing impurities to improve the impurity cleaning effect. The interior of the sewage inlet pipe 4 is provided with a volume adjustment component for automatically adjusting the amount of sewage entering.

[0035] The anti-blocking and impurity removal component includes three filter screens 501 located inside the filter cartridge 2, and a group of connecting rods 502 are fixedly connected to the three filter screens 501. The top of the top connecting rod 502 is fixedly connected to the sealing cover 3, and the bottom of the filter cartridge 2 is fixedly connected to the driving motor 503. The output shaft of the driving motor 503 is fixedly connected to a limiting rod 504, and the limiting rod 504 is slidably connected to a limiting slide 505. The outer wall of the limiting slide 505 is fixedly connected to three groups of fixed water pipes 506, and the three groups of fixed water pipes 506 are fixedly connected to vibration rods 507 arranged in a linear array, among which the bottoms of two groups of fixed water pipes 506 are fixedly connected to a fixed cylinder 508, and the interior of the fixed cylinder 508 is fixedly connected to a compression spring 509, and the bottom end of the compression spring 509 is fixedly connected to a push plate 510, and the bottom of the push plate 510 is fixedly connected to a pressing rod 511. The bottom of the pressing rod 511 is fixedly connected to a debris removal scraping brush 512, one of which is fixedly connected to the top of the limiting rod 504, and the bottom of the debris removal scraping brush 512 conflicts with the filter screen 501. The interior of the sewage inlet pipe 4 is fixedly connected to a spiral sewage plate 513, and the interior of the support leg 1 is rotatably connected to a rotating rod 514, on which a worm gear 516 and two eccentric wheels 515 are fixedly connected. The limiting rod 504 is fixedly connected to a worm 517, and the worm gear 516 and the worm 517 are meshed with each other. The interior of the support leg 1 is symmetrically fixedly connected to a fixed rod 518, and the top of the fixed rod 518 is fixedly connected to the drainage inclined plate 8. A movable plate 519 is slidably connected to the fixed rod 518, and a tension spring 520 fixedly connected to the movable plate 519 is sleeved on the fixed rod 518. The apertures of the three filter screens 501 decrease from top to bottom.

[0036] The inner shape of the limiting slide 505 and the shape of the limiting rod 504 are both cross-shaped;

[0037] The fixed water pipe 506 and the debris removal scraping brush 512 are both distributed in a cross shape, and the debris removal scraping brush 512 is slidably connected to the limiting slide 505;

[0038] Specifically, the anti-blocking and impurity removal component can be used to scrape away impurities accumulated on the top of the filter 501. By continuously rotating and scraping the impurities, the impurities can be effectively prevented from clogging the filter 501 and affecting the filtration efficiency of the sewage. The bottom of the filter 501 is knocked by vibration force, and the impurities clogging the filter 501 can be shaken off by the vibration force, thereby quickly improving the scraping of impurities from the filter 501 and improving the filtration efficiency of the sewage.

[0039] The flushing assembly includes an annular water tank 601 that is rotatably connected to the bottom of the limiting slide 505. The bottom of the annular water tank 601 is fixedly connected to a water inlet pipe 602. The end of the water inlet pipe 602 away from the annular water tank 601 passes through the interior of the support leg 1. Four water inlet grooves 603 are opened inside the limiting slide 505. The fixed water pipes 506 are all interconnected with the water inlet grooves 603. The vibrating rod 507 is internally opened with a flushing nozzle 604, and the flushing nozzle 604 is interconnected with the fixed water pipe 506.

[0040] The limiting slide 505 and the annular water tank 601 are slidably connected to the inside of the drainage inclined plate 8, and the bottom of the annular water tank 601 is in conflict with the movable plate 519;

[0041] Specifically, the flushing component can be continuously rotated and moved up and down to perform reverse flushing from the bottom of the filter 501. The reverse flushing force can increase the flushing force on the filter 501, thereby preventing the filter 501 from being blocked.

[0042] The volume adjustment component includes a hydraulic rod 701 fixedly connected to the top debris removal scraper 512, a fixed sleeve 702 rotatably connected to the interior of the sewage inlet pipe 4, an adjustment plate 703 rotatably connected to the interior of the fixed sleeve 702, a connecting rod 704 rotatably connected to the side close to the hydraulic rod 701 and the adjustment plate 703, and a baffle 705 fixedly connected to the fixed sleeve 702;

[0043] The hydraulic rod 701 is located inside the spiral sewage plate 513;

[0044] Specifically, the amount of sewage entering is adjusted by the adjustment component. When the amount of sewage entering is reduced, the impact force of the water flow on the impurities on the surface of the filter 501 will be reduced, and it will be easier to be cleaned by the scraping tool. This can improve the efficiency and effect of scraping and ensure that the impurities are completely removed.

[0045] Reference Figure 1 and Figure 2 As shown, the outer wall of the support leg 1 is fixedly connected to a drain pipe 9, both sides of the sewage inlet pipe 4 are fixedly connected to handles 10, and a water level sensor is provided inside the drain pipe 9;

[0046] Specifically, the drain pipe 9 can facilitate the discharge of filtered sewage, and the handle 10 can facilitate the pulling of the sewage inlet pipe 4.

[0047] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0048] In the initial state, the worm wheel 516 and the worm 517 are in a meshing state, the side of the eccentric wheel 515 away from the center position is away from the bottom of the movable plate 519, the top of the fixed water pipe 506 is separated from the bottom of the filter screen 501, the bottom of the impurity removal brush 512 is in conflict with the top of the filter screen 501, the compression spring 509 is in a compressed state, the tension spring 520 is in an untensioned state, the telescopic shaft of the hydraulic rod 701 is in a retracted state, and the adjustment plate 703 is vertically located inside the fixed sleeve 702.

[0049] While working:

[0050] The sewage flows into the spiral sewage plate 513 through the sewage inlet pipe 4. The spiral shape of the spiral sewage plate 513 allows the sewage to be transferred to the filter screen 501. The spiral sewage plate 513 can buffer and reduce the flow rate of the sewage, reduce the impact of the sewage on the filter screen 501, and reduce the loss of the filter screen 501. The sewage slides along the spiral sewage plate 513, which increases the residence time of the sewage on the filter screen 501, giving the filter screen 501 more opportunities to capture and intercept impurities. The rotating motion of the spiral sewage plate 513 can help remove some impurities attached to its surface, reduce the amount of impurities entering the filter screen 501, and reduce the burden on the filter screen 501. Through the guidance of the spiral sewage plate 513, the sewage can pass through the filter screen 501 more effectively, thereby improving the overall filtration efficiency. The design of the spiral sewage plate 513 can adapt to sewage with different flow rates to a certain extent, making the filtration process more stable.

[0051] At the same time, the sewage slides onto the filter screen 501 through the spiral sewage plate 513, and the sewage can be filtered and processed in multiple stages in sequence through the three filter screens 501 with different apertures. The filtered sewage is discharged through the drain pipe 9, and when the water volume sensor inside the drain pipe 9 senses that the discharged water volume is gradually decreasing, the water volume sensor immediately sends a signal to the controller, and the controller electrically controls the drive motor 503 and the hydraulic rod 701 to start synchronously. After the drive motor 503 is started, the limit rod 504 fixedly connected to it is driven to rotate. The rotation of the limit rod 504 is limited by the shape of the limit rod 504 and the limit slide 505, which can generate a blocking force between the limit rod 504 and the limit slide 505, so that the rotation of the limit rod 504 drives the limit slide 505 to rotate synchronously, and the limit The rotation of the rod 504 and the limiting slide 505 drives the fixed water pipe 506 and one of the debris removal scraping brushes 512 fixed thereto to rotate synchronously, the rotation of the fixed water pipe 506 drives the vibration rod 507 to rotate synchronously, the rotation of the fixed water pipe 506 drives the fixed cylinder 508 fixed thereto to rotate, the rotation of the fixed cylinder 508 drives the internal compression spring 509 and the push plate 510 to rotate synchronously, the rotation of the push plate 510 drives the pressing rod 511 fixed thereto to rotate synchronously, the rotation of the pressing rod 511 drives the debris removal scraping brush 512 fixed thereto to rotate synchronously, and the elastic force of the compression spring 509 itself makes the bottom of the debris removal scraping brush 512 always conflict with the top of the filter 501, so that the debris removal scraping brush 512 can be used to scrape the impurities accumulated on the filter 501;

[0052] At the same time, the rotation of the limit rod 504 drives the worm 517 fixedly connected to it to rotate, and the rotation of the worm 517 drives the worm gear 516 meshing with it to rotate, and the rotation of the worm gear 516 drives the rotating rod 514 fixedly connected to it to rotate, and the rotating rod 514 drives the eccentric wheel 515 fixedly connected to it to rotate synchronously. At this time, the tension spring 520 is in a stretched state. Then, when the eccentric wheel 515 rotates, the eccentric wheel 515 can be separated from the bottom of the movable plate 519 away from the center side of the rotating rod 514. When the movable plate 519 has no thrust, the pulling force of the tension spring 520 pulls the movable plate 519 downward, and the sliding of the movable plate 519 can make the limit slide 505 that contacts the surface push the limit slide 505 when sewage enters. The slide 505 slides downward on the limit rod 504, and the downward movement of the limit slide 505 drives the fixed water pipe 506 fixed thereto to slide downward, and the downward movement of the fixed water pipe 506 drives the vibrating rod 507 fixed thereto to slide downward synchronously, so that the top of the vibrating rod 507 is separated from the bottom of the filter screen 501, and when the two vibrating rods 507 slide downward and separate from the filter screen 501, the downward movement of the fixed water pipe 506 pushes the fixed cylinder 508 fixed thereto to slide downward, so that the push plate 510 and the pressing rod 511 slide downward inside the fixed cylinder 508, and the push plate 510 compresses the compression spring 509, while the limit rod 504 and the limit slide 505 are still in a state of continuous rotation during the sliding process, and the eccentric wheel 51 When the side away from the center rotates to the bottom of the movable plate 519, the eccentric distance can push the movable plate 519 to slide upward, and the upward sliding of the movable plate 519 pushes the annular water tank 601 and the limiting slide 505 that are in conflict with it to slide upward synchronously. The upward sliding of the limiting slide 505 pushes the fixed water pipe 506 and the vibration rod 507 fixedly connected thereto to slide upward, so that the top of the vibration rod 507 conflicts with the bottom of the filter 501. While the fixed water pipe 506 and the vibration rod 507 continue to rotate, the bottom of the filter 501 is vibrated and knocked up and down. By rotating and scraping the upper surface of the filter 501, the dirt and impurities attached to the surface can be effectively removed. At the same time, the knocking and vibration of the bottom of the filter 501 can remove the accumulated dirt and impurities on the bottom of the filter 501. The sediment and particles on the outside are loosened and removed to ensure the overall cleanliness of the filter 501. The continuous scraping and vibration action helps prevent dirt from forming lumps on the surface of the filter 501, reduces the risk of clogging, and maintains the patency of the filter 501. The clean filter 501 can better filter sewage, improve filtration efficiency, reduce the resistance of the filter 501, and ensure the normal operation of the system. The rotating scraping and up and down sliding actions can make the filter 501 subject to uniform force to avoid local excessive wear or damage. Knocking and vibrating the bottom of the filter 501 can remove stubborn impurities accumulated at the bottom, achieve a deeper cleaning effect, extend the service life of the filter 501, and reduce the cost of frequent replacement of the filter 501.Ensuring that the filter 501 is clean and in good condition helps improve the quality of the filtered sewage and reduces the amount of impurities that pass through the filter 501;

[0053] At the same time, while the bottom of the filter 501 is vibrated and struck, the water enters the annular water tank 601 through the water inlet pipe 602 through the external flushing equipment, and the water in the annular water tank 601 continuously enters the water inlet groove 603, and the water then enters the fixed water pipe 506 through the water inlet groove 603. The water flushes the filter 501 from the bottom through the multiple vibration rods 507 on the fixed water pipe 506. At this time, the fixed water pipe 506 and the vibration rod 507 are in a state of continuous rotation and continuous up and down vibration, and the sprayed water continues to rotate and moves up and down reciprocatingly from the bottom to the bottom of the filter 501. This flushing method can flush all parts of the filter 501, including the areas at the bottom where pollutants are easily accumulated. , the up and down sliding and rotating actions can effectively remove the dirt on the surface and inside of the filter 501, ensuring a comprehensive cleaning effect. The continuous rotation and up and down sliding actions can increase the impact of the flushing water, which helps to break the attachment of dirt to the filter 501, making it easier to be rinsed away, and can improve the efficiency and effect of flushing. The bottom is the area where the filter 501 is easily clogged. The rotating and sliding actions can make the flushing water evenly distributed on the surface of the filter 501, avoiding uneven flushing and ensuring that all parts of the filter 501 can be fully rinsed. The thoroughly cleaned filter 501 can better play a filtering role and improve the ability to retain suspended matter and particulate matter in sewage, thereby improving the overall filtering effect;

[0054] At the same time, while the impurities on the upper surface and bottom of the filter screen 501 are being scraped synchronously, the telescopic shaft of the hydraulic rod 701 can be controlled by the controller to retract, and the retracting movement of the hydraulic rod 701 pulls the connecting rod 704 rotating with it to slide down, and the connecting rod 704 pulls one end of the connected adjusting plate 703 to pull down, and the downward pulling force can make the adjusting plate 703 rotate inside the fixed sleeve 702. At this time, the adjusting plate 703 is in a state of being vertically in the fixed sleeve 702, and the size of the opening at the edge of the adjusting plate 703 and the edge of the fixed sleeve 702 can be adjusted to achieve the size of the sewage entering. By reducing the amount of sewage entering, the filter 501 can be subjected to less impact of water flow, making it easier to remove impurities attached to it, which can ensure that the dirt on the surface of the filter 501 is more thoroughly removed and the scraping effect is improved. Reducing the amount of sewage entering can reduce the load on the filter 501 and prevent excessive impurities from clogging the filter 501 during the scraping process, which helps to keep the filter 501 unobstructed and ensure its normal filtering function. When the amount of sewage entering is reduced, the scraping operation can be carried out more carefully and thoroughly, and there can be more time and opportunities to remove impurities on the surface of the filter 501, thereby improving the quality of scraping.
