Description

Technical Field

[0001] This invention relates to the field of filtration technology, and more particularly to a multi-layer high-speed flow water supply and drainage filtration device. Background Technology

[0002] With rapid urbanization and stricter environmental standards, filtration devices in water supply and drainage systems have become crucial for ensuring water quality, preventing pipe blockages, and improving water resource utilization. Traditional filtration devices typically employ single-layer or multi-layer fixed filter structures, separating impurities through mechanical interception. To improve efficiency, self-cleaning filters with backwashing or scraping functions have emerged in existing technologies, and some devices can even utilize water flow to drive simple mechanical structures for periodic cleaning. These devices reduce maintenance frequency to some extent and are widely used in municipal water supply, industrial circulating water, building drainage, and agricultural irrigation.

[0003] However, traditional self-cleaning filters still have significant shortcomings. Their cleaning actions mostly rely on fixed time cycles or manual triggering, and cannot respond accurately according to the actual degree of filter clogging, resulting in untimely cleaning or water waste. The cleaning process is often independent of the sewage system, and the scraped-off pollutants are prone to secondary accumulation inside the device, which may cause repeated clogging of the filter. Most devices lack water recycling design, and the backwash water consumption is large, resulting in limited energy-saving effect. The traditional filter structure is fixed, making it difficult to dynamically adjust the filtration status according to changes in water quality, and key components lack effective protection, resulting in insufficient long-term operational stability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the cleaning action of the water supply and drainage system mostly depends on a fixed time period or manual triggering. The present invention provides a multi-layer high-speed flow water supply and drainage filtration device, which can solve the problem that the cleaning action of the water supply and drainage system mostly depends on a fixed time period or manual triggering.

[0005] To solve the above problems, the following technical solutions are provided: A multi-layer high-speed flow water supply and drainage filtration device is designed, comprising a first filter screen, a first scraper fixedly connected to the outer surface of the first filter screen, a through groove provided on the outer surface of the first scraper, a second filter screen movably connected to the outer surface of the first scraper, an extension ring fixedly connected to the top of the first scraper, a fixing ring fixedly connected to the top of the second filter screen, a filter cylinder fixedly connected to the bottom of the fixing ring, a threaded rod movably connected to the inside of the first filter screen, a sealing plate movably installed inside the first filter screen, the bottom of the threaded rod connected to the sealing plate, and a drive cavity movably connected to the top of the extension ring. The drive chamber ensures a seal between the extension ring and the fixed ring, allowing water to flow from the first filter screen to the second filter screen. A sealing ring is fixedly connected to the bottom of the second filter screen, ensuring that the water flows in a fixed direction. A third filter screen is fixedly connected to the outer wall of the sealing ring, and a bottom sealing plate is movably installed on the inner wall of the third filter screen. A rotating rod is movably connected to the top of the bottom sealing plate, and a telescopic connecting rod is fixedly connected to the top of the rotating rod. The top of the telescopic connecting rod is connected to the bottom of the sealing plate. When the first filter screen becomes clogged, the increased water pressure pushes the first filter screen down while simultaneously scraping away the deposits on the inner wall of the second filter screen.

[0006] Furthermore, an initial filter plate is fixedly connected to the top of the drive chamber, an inlet tank is fixedly connected to the top of the initial filter plate, a connecting rod is movably connected to the bottom of the initial filter plate, an impeller is fixedly connected to the bottom of the connecting rod, a telescopic connecting shaft is fixedly connected to the bottom of the impeller, a differential is fixedly connected to the bottom of the telescopic connecting shaft, and the bottom of the differential is connected to a threaded rod. When water flows into the drive chamber, it causes the impeller to rotate, which in turn drives the threaded rod to rotate, compressing the deposits on the inner wall of the first filter screen above the sealing plate.

[0007] The above technical solution achieves automated operation of filtration, unclogging, and sewage discharge through a clever combination of water pressure drive and mechanical linkage. When the first filter screen becomes clogged, causing an increase in water pressure, the device automatically triggers the first filter screen to descend, using the first scraper to remove deposits from the inner wall of the second filter screen. Simultaneously, the incoming water flow drives the impeller to rotate the threaded rod, compressing and collecting the impurities intercepted by the first filter screen above the sealing plate, effectively preventing rapid clogging of the filter screen pores. Each filter screen and sealing component works together to force water flow along a preset path for step-by-step filtration, improving filtration efficiency and impurity retention capacity. The linkage design of the differential and telescopic structure ensures the coordination and reliability of each component's actions, reduces the frequency of manual cleaning, and maintains stable and unobstructed water flow.

[0008] Furthermore, an eccentric wheel one is movably connected to the top of the initial filter plate, a connecting strip is movably connected to the top of the eccentric wheel one, and an eccentric wheel two is movably connected to the bottom of the connecting strip. The eccentric wheel one transmits power to the eccentric wheel two, a transmission rod is fixedly connected to the bottom of the eccentric wheel two, and a transmission gear is fixedly connected to the bottom of the transmission rod.

[0009] The above technical solution converts the kinetic energy of the incoming water flow into mechanical transmission, enabling continuous or periodic operation of the internal cleaning components. The coordinated transmission of eccentric wheel one and eccentric wheel two transforms the initial motion at the filter plate into the stable rotation of the transmission gear, thereby driving the subsequent scraping or stirring mechanism. This effectively prevents the accumulation and caking of dirt on the filter screen surface, enhances self-cleaning ability, makes the filtration process more continuous and efficient, and reduces energy consumption and manual intervention.

[0010] Furthermore, a bearing is fixedly connected to the bottom of the filter cartridge, and a driven gear is fixedly connected to the outer surface of the outer ring of the bearing, the driven gear being adapted to the transmission gear.

[0011] Furthermore, an acceleration channel is fixedly connected to the bottom of the driven gear. The rotation of the acceleration channel increases the speed of the water flowing out of the acceleration channel. A transfer groove is movably installed on the outer surface of the acceleration channel. An electric control valve is fixedly installed at the bottom of the transfer groove. An output pipe is fixedly connected to the bottom of the electric control valve.

[0012] The aforementioned technical solution uses gear transmission to drive the rotation of the acceleration channel, utilizing centrifugal force to rapidly concentrate the wastewater or impurities collected there. The acceleration channel is connected to an electrically controlled valve and output pipeline, forming an independent, rapid sewage discharge path. The electrically controlled valve, as the control core, can precisely open based on internal pressure signals or timing commands, directly and quickly discharging the high-concentration wastewater that has been centrifuged and concentrated outside the device. This design achieves efficient separation and targeted discharge of impurities from the main filtration flow, avoiding secondary circulation or accumulation of pollutants within the system, significantly improving sewage discharge efficiency and the continuous working capacity of the entire filtration system.

[0013] Furthermore, a supporting rotating rod is movably connected to the inner wall of the transfer trough, an impeller is fixedly connected to the top of the supporting rotating rod, a rotating column is fixedly connected to the top of the impeller, the rotating column extends to the top of the bottom sealing plate and connects to the rotating rod, and an inner scraper is fixedly connected to the top of the rotating rod, the inner scraper being adapted to the inner wall of the third filter screen.

[0014] The aforementioned technical solution converts the energy of the water flow during the sewage discharge process into internal cleaning power. When the accelerated water flow in the transfer tank drives the impeller to rotate, the power is transmitted to the inner scraper blades via the rotating column and rod, causing the blades to continuously scrape the inner wall of the third filter screen. This process achieves simultaneous "sewage discharge" and "self-cleaning": while the concentrated waste is discharged by the electrically controlled valve, its kinetic energy is immediately recovered and used to remove deposits from the inner wall of the third filter screen, effectively preventing the filter screen from clogging due to waste buildup, and improving filtration efficiency and the system's self-maintenance capabilities.

[0015] Furthermore, a water pump is fixedly connected to one side of the transfer tank, and a water storage tank is fixedly connected to the top of the water pump. An infrared sensor is fixedly installed on the upper part of the inner wall of the water storage tank. After the infrared sensor detects that the water level has reached a specified height, the water pump discharges the water.

[0016] The aforementioned technical solution involves the accelerated and relatively cleaned filtered water or backwash water in the transfer tank being actively pumped into a storage tank, eliminating the system's tendency to simply wait for the tank to fill before discharging. Infrared sensors monitor the water level in real time, and once the storage tank reaches the predetermined level, the stored water can be automatically or controlled for use within the device. This achieves a closed-loop utilization of the filtration system's own produced water, transforming traditionally discharged wastewater into a self-cleaning water source, significantly reducing external water demand, and substantially improving the device's water-saving capabilities and operational economy.

[0017] Furthermore, a supporting arc-shaped plate is fixedly installed on the inner wall of the filter cylinder, an electric push rod is fixedly connected to the top of the supporting arc-shaped plate, a connecting arc-shaped plate is fixedly connected to the top of the electric push rod, and one side of the connecting arc-shaped plate is connected to the outer surface of the third filter screen.

[0018] The above technical solution achieves precise control of the support posture of the third filter screen through an electric push rod. The supporting arc plate is fixed to the inner wall of the filter cylinder as a stable base. The electric push rod can extend and retract according to instructions, thereby raising or lowering the connecting arc plate and indirectly adjusting the vertical position of the connected third filter screen. During self-cleaning, the electric push rod moves to open the gap between the third filter screen and the sealing ring, and the telescopic connecting rod drives the sealing plate to move downward, simultaneously cleaning the deposits accumulated on the top of the sealing plate.

[0019] Furthermore, the inner wall of the filter cylinder is provided with an outlet, and a support ring is fixedly installed on the outer surface of the filter cylinder. An electric push rod is fixedly installed on the top of the support ring, and a movable retaining ring is fixedly connected to the top of the electric push rod, which can block the outlet.

[0020] The above technical solution achieves precise and automated management of the filter cartridge's wastewater discharge process through an electric actuator. The electric actuator drives the movable retaining ring to rise and fall, thus tightly sealing or opening the discharge port on the filter cartridge wall. When impurities accumulate inside the filter cartridge and cleaning is required, the electric actuator retracts, causing the movable retaining ring to descend and open the discharge port, allowing the concentrated wastewater to be discharged by the water flow. After cleaning, the electric actuator extends, pushing the movable retaining ring upward to re-close the discharge port, ensuring the normal operation of the filtration process. This design replaces traditional manual valves, achieving rapid, reliable, and remotely controllable opening and closing of the wastewater discharge process, significantly improving the automation level and operating efficiency of the entire filtration device.

[0021] Furthermore, a protective shell is fixedly connected to the bottom of the water inlet tank, and the bottom of the protective shell is adapted to the output pipe.

[0022] The aforementioned technical solution tightly encloses or supports the outlet end of the output pipe through a protective shell structure. Its main function is to provide robust physical protection for this internal component. It effectively prevents external foreign objects from impacting the pipe opening, avoiding mechanical damage that may occur during equipment assembly, operation, or maintenance.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This multi-layer high-speed flow water supply and drainage filtration device features highly efficient, fully automated filtration and self-cleaning. Driven by water pressure and linked with precision machinery, the device achieves full automation of the filtration, blockage identification, scraping and cleaning, impurity compression, and sewage discharge process. When the first filter screen becomes clogged, causing an increase in water pressure, the system automatically triggers the first filter screen to descend, using the first scraper to remove deposits from the second filter screen. Simultaneously, the incoming water flow drives the impeller to rotate the threaded rod, compressing impurities above the sealing plate, effectively delaying filter screen clogging. Each layer of filter screen and the sealing assembly form a forced, step-by-step filtration path, significantly improving filtration efficiency and impurity retention capacity, and greatly reducing the need for manual intervention. 2. This multi-layer high-speed flow water supply and drainage filtration device features an energy-saving and environmentally friendly sewage discharge and water circulation system. The device is equipped with an independent centrifugal accelerated sewage discharge channel, which can efficiently separate and discharge concentrated sewage at designated points, avoiding secondary accumulation of pollutants within the system. At the same time, through the water pump and water storage tank in conjunction with an infrared sensor, the backwash water or filtered water can be recycled and stored. The stored water can be used for internal self-cleaning of the device, forming a closed-loop utilization of water resources. This design not only significantly reduces external water demand, but also further improves the energy efficiency and operational economy of the system through energy recovery (such as using the sewage flow to drive the impeller to drive the internal scraper to clean the third filter screen). 3. This multi-layer high-speed flow water supply and drainage filtration device features an adjustable and highly reliable modular structure. The device employs multiple electric actuators (such as electric push rods one and two) and adjustable components to achieve precise control over key parameters such as filter screen posture, drain port opening and closing, and self-cleaning gap. Protective housings and other structures provide physical protection for critical internal components, ensuring long-term operational stability. The entire system combines modularity, programmability, and high adaptability, making it suitable for various operating conditions and significantly improving the equipment's intelligence level and maintenance convenience.

[0026] 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.

[0027] like Figure 1 - Figure 5As shown, this embodiment provides a multi-layer high-speed flow water supply and drainage filtration device, including a first filter screen 1, a first scraper 2 fixedly connected to the outer surface of the first filter screen 1, a through groove 3 provided on the outer surface of the first scraper 2, a second filter screen 4 movably connected to the outer surface of the first scraper 2, an extension ring 5 fixedly connected to the top of the first scraper 2, a fixing ring 6 fixedly connected to the top of the second filter screen 4, a filter cylinder 26 fixedly connected to the bottom of the fixing ring 6, a threaded rod 7 movably connected inside the first filter screen 1, a sealing plate 8 movably installed inside the first filter screen 1, the bottom of the threaded rod 7 connected to the sealing plate 8, and a driving cavity 47 movably connected to the top of the extension ring 5. The driving cavity 47 ensures a seal between the extension ring 5 and the fixing ring 6, allowing water to flow from the first filter screen 1 to the second filter screen 4. A sealing ring 9 is fixedly connected to the bottom of the second filter screen 4, ensuring that the water flows in a fixed direction. A third filter screen 10 is fixedly connected to the outer wall of the sealing ring 9. A bottom sealing plate 11 is movably installed on the inner wall of the third filter screen 10. A rotating rod 12 is movably connected to the top of the bottom sealing plate 11. A telescopic connecting rod 36 is fixedly connected to the top of the rotating rod 12. The top of the telescopic connecting rod 36 is connected to the bottom of the sealing plate 8. When the first filter screen 1 is clogged, the water pressure increases, pushing the first filter screen 1 down and scraping away the deposits on the inner wall of the second filter screen 4. An initial filter plate 15 is fixedly connected to the top of the drive chamber 47. An inlet tank 14 is fixedly connected to the top of the initial filter plate 15. A connecting rod 18 is movably connected to the bottom of the initial filter plate 15. An impeller 19 is fixedly connected to the bottom of the connecting rod 18. The bottom of impeller 19 is fixedly connected to a telescopic connecting shaft 20, and the bottom of the telescopic connecting shaft 20 is fixedly connected to a differential 21. The bottom of the differential 21 is connected to a threaded rod 7. Water flows into the drive chamber 47, causing impeller 19 to rotate and driving the threaded rod 7 to rotate, compressing the deposits on the inner wall of the first filter screen 1 onto the sealing plate 8. The top of the initial filter plate 15 is movably connected to an eccentric wheel 16, and the top of the eccentric wheel 16 is movably connected to a connecting strip 17. The bottom of the connecting strip 17 is movably connected to an eccentric wheel 22. The eccentric wheel 16 transmits power to the eccentric wheel 22. The bottom of the eccentric wheel 22 is fixedly connected to a transmission rod 23, and the bottom of the transmission rod 23 is fixedly connected to a transmission gear 24. The bottom of the filter cylinder 26 is fixedly connected to a bearing 27. A driven gear 25 is fixedly connected to the outer surface of the outer ring 7. The driven gear 25 is adapted to the transmission gear 24. An acceleration channel 28 is fixedly connected to the bottom of the driven gear 25. The rotation of the acceleration channel 28 increases the speed of the water flowing out of the acceleration channel 28. A transfer groove 29 is movably installed on the outer surface of the acceleration channel 28. An electric control valve 37 is fixedly installed at the bottom of the transfer groove 29. An output pipe 38 is fixedly connected to the bottom of the electric control valve 37. A support rod 32 is movably connected to the inner wall of the transfer groove 29. An impeller 31 is fixedly connected to the top of the support rod 32. A rotating column 30 is fixedly connected to the top of the impeller 31. The rotating column 30 extends to the top of the bottom sealing plate 11 and connects to the rotating rod 12. An inner scraper 13 is fixedly connected to the top of the rotating rod 12.The inner scraper 13 is adapted to the inner wall of the third filter screen 10. After the water flows in from the inlet tank 14, it first passes through the initial filter plate 15 for primary filtration. Subsequently, the water flows into the drive chamber 47 and drives the impeller 19 to rotate. The impeller 19 transmits the rotational motion to the threaded rod 7 through the telescopic connecting shaft 20 and the differential 21, driving the sealing plate 8 to rotate, thereby rotating and compacting the impurities intercepted by the first filter screen 1 to prevent the filter holes from clogging quickly. When the first filter screen 1 becomes clogged due to the accumulation of impurities, the inlet water pressure increases, pushing the entire first filter screen 1 downward. At this time, the first scraper 2 fixed on the outer wall of the first filter screen 1 also descends, scraping off the dirt attached to the inner wall of the second filter screen 4, achieving self-cleaning. At the same time, the transmission system composed of the eccentric wheel 16, connecting bar 17, eccentric wheel 22, transmission rod 23 and transmission gear 24 converts the kinetic energy of the inlet water flow into the continuous rotation of the transmission gear 24, which in turn drives the driven gear 25 meshing with the transmission gear 24 to rotate. Driven gear 25 drives the bottom acceleration channel 28 to rotate, using centrifugal force to accelerate the collected sewage. The accelerated sewage enters the transfer tank 29 for temporary storage and is then discharged centrally via the output pipe 38 through the controlled electronic valve 37, either periodically or as needed. During this process, the water flowing through the transfer tank 29 simultaneously drives impeller 2 31 to rotate. Impeller 2 31, through rotating column 30, drives rotating rod 12 and the inner scraper 13 fixed at its top to rotate, causing the inner scraper 13 to continuously scrape the inner wall of the third filter screen 10, achieving synchronous cleaning of the third filter screen 10, thereby ensuring that the entire multi-layer filtration system remains efficient and unobstructed during operation.

[0028] Preferably, a water pump 39 is fixedly connected to one side of the transfer tank 29, and a water storage tank 40 is fixedly connected to the top of the water pump 39. An infrared sensor 41 is fixedly installed on the upper part of the inner wall of the water storage tank 40. After the infrared sensor 41 detects that the water level has reached a specified height, the water pump 39 discharges water. A supporting arc plate 33 is fixedly installed on the inner wall of the filter cylinder 26. An electric push rod 35 is fixedly connected to the top of the supporting arc plate 33. A connecting arc plate 34 is fixedly connected to the top of the electric push rod 35. One side of the connecting arc plate 34 is connected to the outer surface of the third filter screen 10. An outlet 44 is provided on the inner wall of the filter cylinder 26. A supporting ring 42 is fixedly installed on the outer surface of the filter cylinder 26. An electric push rod 43 is fixedly installed on the top of the supporting ring 42. A movable retaining ring 45 is fixedly connected to the top of the electric push rod 43. The movable retaining ring 45 can block the outlet 44. The water pump 39 pumps the water in the transfer tank 29 into the water storage tank 40 for storage. When the infrared sensor 41 detects that the water level has reached the preset height, the water pump 39 starts to discharge the water in the storage tank 40. This stored water can be used for internal self-cleaning and other recycling purposes. The supporting arc plate 33 on the inner wall of the filter cylinder 26, together with the electric push rod 35 and the connecting arc plate 34, form a filter screen adjustment mechanism. The extension and retraction of the electric push rod 35 can drive the connecting arc plate 34 to rise and fall, thereby adjusting the vertical position or tension of the third filter screen 10. The outlet 44 on the wall of the filter cylinder 26 is controlled by the movable retaining ring 45 driven by the electric push rod 43 through the support ring 42: when the electric push rod 43 retracts, the movable retaining ring 45 descends to open the outlet 44 for sewage discharge; when the electric push rod 43 extends, the movable retaining ring 45 rises to close the outlet 44 to maintain the normal filtration process. This series of electric actuators together realizes the automated operation of water recovery, filter screen state adjustment, and sewage discharge control.

[0029] Preferably, a protective shell 46 is fixedly connected to the bottom of the inlet tank 14. The bottom of the protective shell 46 is adapted to the outlet pipe 38. The protective shell 46 is fixed to the bottom of the inlet tank 14, and its lower port is precisely aligned and adapted to the outlet end of the outlet pipe 38. The main function of this structure is to provide a stable support and physical protection for the outlet pipe 38, a critical internal component, to prevent damage to the pipe opening from collisions or accidental impacts by external foreign objects. This ensures that the high-pressure water flow or sewage discharged from the outlet pipe 38 can be safely guided and collected, thereby guaranteeing the integrity of the entire sewage discharge path and the reliability of long-term operation.

[0030] This embodiment presents a multi-layer high-speed flow water supply and drainage filtration device. Water enters from the inlet tank 14, first undergoes primary filtration via the initial filter plate 15, and then enters the lower drive chamber 47. The water flow drives the impeller 19 to rotate. This rotational motion is transmitted to the threaded rod 7 via the telescopic connecting shaft 20 and the differential 21, causing the sealing plate 8 to rotate and compact the impurities intercepted by the first filter screen 1, delaying filter pore clogging. When the first filter screen 1 becomes clogged due to impurity accumulation, the inlet pressure increases, pushing the entire first filter screen 1 and its fixedly connected first scraper 2 downwards. During this descent, the first scraper 2 scrapes away the deposits on the inner wall of the second filter screen 4, completing a pressure-triggered self-cleaning process. Simultaneously, the water flow impact causes the initial filter plate 15 to vibrate, driving the eccentric wheel 16 to move. The power is transmitted via the connecting bar 17 to the second eccentric wheel 22, ultimately driving the transmission gear 24 to rotate continuously. The transmission gear 24 meshes with the driven gear 25, driving the acceleration channel 28 to rotate. Centrifugal force is used to accelerate and concentrate the sewage flowing into it. The sewage then enters the transfer tank 29 for temporary storage. The electrically controlled valve 37 opens periodically according to preset instructions or system pressure signals, quickly discharging the concentrated sewage through the output pipe 38. As the sewage flows through the transfer tank 29, the water flow simultaneously drives the impeller 31 to rotate. This rotational force is transmitted to the inner scraper 13 through the rotating column 30 and rotating rod 12, causing the inner scraper 13 to continuously scrape the inner wall of the third filter screen 10, achieving simultaneous sewage discharge and deep filter screen self-cleaning. Water pump 39 draws water from transfer tank 29 to storage tank 40. When infrared sensor 41 detects that the water level has reached the set value, water pump 39 pumps the stored water back into the device for backwashing or to replenish cleaning water, realizing water recycling. The supporting arc plate 33 inside filter cylinder 26, together with electric push rod 1 35 and connecting arc plate 34, constitutes a filter screen adjustment mechanism, which can adjust the vertical position or tension of the third filter screen 10 as needed. When sewage discharge is required, electric push rod 2 43 retracts, driving the movable retaining ring 45 to descend and opening the discharge port 44 on the wall of filter cylinder 26; after sewage discharge, electric push rod 2 43 extends, pushing the movable retaining ring 45 to rise and re-close the discharge port 44. Throughout the process, the protective shell 46 fixed to the bottom of the inlet tank 14 provides physical protection for the outlet of the output pipe 38, ensuring the safety and reliability of the sewage discharge path.
