Description

Technical Field

[0001] This invention belongs to the technical field of pure water purification devices, and more specifically, it relates to a self-draining pure water purification device with adaptive flow regulation. Background Technology

[0002] In the process of water purification, pure water purification devices are the core equipment for maintaining water quality safety and are widely used in many scenarios such as municipal water supply, industrial circulating water, and drinking water treatment. However, traditional pure water purification devices have revealed many unavoidable defects during long-term operation: as the core component of filtration, the filter element's surface will continuously accumulate stubborn dirt due to the continuous deposition of suspended particles, microbial debris, and mineral crystals in the water. This dirt not only clogs the filter element pores, causing a surge in filtration resistance and a significant decrease in water flow velocity, but also breeds bacteria, forming secondary pollution and seriously affecting the stability of purified water quality.

[0003] In existing technologies, traditional methods rely on manual disassembly, cleaning, or replacement of filter cartridges periodically. However, manual operation not only incurs significant labor costs, but in large-scale purification systems, a single maintenance operation requires several hours of downtime, severely impacting water supply continuity. Traditional devices lack dynamic control capabilities and cannot adjust their operating status based on real-time parameters such as influent flow rate and water turbidity. When the influent flow rate increases sharply, the filtration load can easily become too heavy, leading to substandard water quality; conversely, when the flow rate is too low, the slow water velocity can cause accelerated buildup of dirt on the filter cartridge surface, potentially resulting in inadequate filtration and wasted water and energy resources. This fails to meet the high-efficiency, energy-saving, and intelligent operation requirements of modern purification systems. Therefore, developing a purification device that can automatically clean dirt and dynamically adapt to changes in flow rate has become an urgent industry need.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an adaptive flow control self-draining pure water purification device in order to achieve a more practical and valuable purpose. Summary of the Invention

[0005] This invention provides an adaptive flow rate control self-draining pure water purification device to overcome the above-mentioned defects in the prior art.

[0006] The purpose and effectiveness of this invention's adaptive flow control self-draining pure water purification device are achieved through the following specific technical means:

[0007] An adaptive flow control self-draining pure water purification device includes a lower tank, an upper tank connected above the lower tank via a middle flange ring, a drive assembly fixedly connected above the upper tank via an upper cover flange, a water filtration chamber inside the upper tank, a filter cartridge installed inside the water filtration chamber, and a cleaning component for cleaning dirt installed on the surface of the filter cartridge.

[0008] The cleaning component includes a scraping cleaning device and a cleaning disc. The scraping cleaning device makes contact with the outer wall of the filter cartridge to achieve scraping. The dirt after scraping and cleaning falls onto the cleaning disc through the inclined guide plate provided in the scraping cleaning device and is crushed into blocks.

[0009] The bottom of the filter cartridge is equipped with a central drive component, which uses the drive assembly to adsorb, store, and isolate the crushed dirt.

[0010] A further technical solution involves a middle flange ring fixedly connected to the upper end of the lower tank body. The middle flange ring has a groove within it, and a base is fixedly installed within the groove. The base and the middle flange ring are fastened together with bolts to ensure connection stability. A pressure-boosting rotation device is fixedly installed inside the base. This device includes a rotating gear, a drive gear, and a central drive component. The rotating gear and drive gear are meshed on the outer side of the central drive component. The rotating gear and drive gear are positioned opposite each other, forming a stable transmission structure with the central drive component. The rotating gear, drive gear, and central drive component are horizontally distributed to ensure balanced force during transmission. The rotating gear includes a first gear and an upper rotating shaft. The upper rotating shaft passes through the middle of the first gear, and the upper rotating shaft and the first gear are connected by a key to achieve synchronous rotation.

[0011] A further technical solution includes a central drive component comprising a gear ring sleeve and turbine rotating blades. The gear ring sleeve has an internal bottom cover, which is integrally formed with the gear ring sleeve to enhance overall strength. The bottom cover has four sets of through grooves arranged in an array for the flow of water and dirt. A bearing is located at the center of the bottom cover to reduce frictional resistance during the rotation of the upper shaft. Multiple sets of turbine rotating blades are arranged in a ring array on the bottom cover. These turbine rotating blades are rectangularly bent, and their outer surfaces feature wavy convex patterns, which enhance the disturbance and adsorption effect on the water. One end of the upper shaft is rotatably connected to the bottom cover, and the other end is fixedly connected to the drive component. A rotating shaft is rotatably connected to the bottom of the drive gear, and the rotating shaft is fixedly connected to the bottom cover. The drive gear and the first gear mesh with the gear ring sleeve, and the rotation of the central drive component is achieved through the meshing transmission between the gears.

[0012] A further technical solution includes a storage cavity inside the lower tank for temporarily storing water containing dirt. A drain pipe is installed inside the storage cavity. One end of the drain pipe passes through the middle flange and is fixedly connected to the filter cartridge. A sealing gasket is provided at the connection to prevent leakage. The other end of the drain pipe passes through the lower tank wall and is fixedly connected to an outlet. A rotating blade is also fixedly installed on the drain pipe. The rotating blade can buffer and block the water flow. The rotating blade and the turbine rotor are arranged vertically so that they do not interfere with each other and can work together during operation.

[0013] A further technical solution includes a cleaning box, with a circular opening in the middle that matches the shape of the filter cartridge. Extended steel brushes are fixedly installed at the upper and lower ends of the circular opening, and these extended steel brushes contact the outside of the filter cartridge to perform preliminary cleaning of the surface. The surface of the cleaning box has a through hole, and a swing plate is rotatably installed inside the through hole. The swing plate can rotate under the impact of water flow, and when dirt is captured, the swing plate can effectively prevent dirt from floating.

[0014] A further technical solution includes a cleaning disc inside the cleaning box, which is connected to the cleaning box via bearings to achieve relative rotation. The surface of the cleaning disc has a ring array of several sets of central protrusions, which enhance the structural strength of the cleaning disc. A gap is provided between every two sets of central protrusions, and a scraping cleaning device is fixedly installed within the gap. The scraping cleaning device includes a second scraper and a first scraper. The second and first scrapers are located on both sides of the central protrusion. A compression spring is fixedly connected to the side of the second and first scrapers closest to the central protrusion, providing continuous pressure to ensure close contact between the scraper and the filter cartridge surface. The compression spring is fixedly connected to the central protrusion. Several sets of inclined guide plates are connected between the second and first scrapers, guiding dirt to slide down. The ends of the inclined guide plates are aligned between the cleaning disc and the central protrusion. The several sets of inclined guide plates are arranged in a stepped manner from bottom to top, facilitating the gradual sliding of dirt into the rolling groove.

[0015] A further technical solution involves a rolling groove between the central protrusion and the outer edge of the cleaning disc. The rolling groove provides a rolling track for the crushing ball, which rolls inside the rolling groove. When the crushing ball rolls, it contacts the second scraper and the first scraper. The rolling of the crushing ball is achieved by the pushing action of the scrapers. The second scraper is longer than the first scraper, and there is a gap between the front end of the second scraper and the front end of the first scraper. This gap is used to store soil. The dirt scraped off the scraper will fall onto the stepped inclined guide plate, thereby rolling into the rolling groove. The crushing ball will then contact the dirt and crush it into blocks.

[0016] A further technical solution includes a drive gear ring fixedly connected to the central protrusion and the outer side of the cleaning disc. The drive gear ring rotates synchronously with the cleaning disc. A rotary bearing is provided on the outer side of the drive gear ring to reduce friction during rotation. A first drive gear disk and a second drive gear disk mesh on the outer sides of the two sets of drive gear rings. A rotating central shaft passes through the first drive gear disk and the second drive gear disk, driving the two gear disks to rotate synchronously. A spiral worm gear is fixedly connected to the outer side of the rotating central shaft, and the spiral worm gear cooperates with the drive worm to achieve power transmission.

[0017] A further technical solution includes a spiral sleeve connected to the outer side of the cleaning box, which is fixedly connected to the cleaning box. The upper and lower sections of the spiral sleeve have gear grooves that cooperate with a drive worm to achieve the up-and-down movement of the cleaning component. The middle section of the spiral sleeve is empty. The driving component includes a drive motor, the output end of which is fixedly connected to a drive worm. The drive motor provides power to the entire device. The surface of the drive worm cooperates with the gear grooves on the upper and lower sections of the spiral sleeve. A spiral worm wheel is located in the empty section of the spiral sleeve and cooperates with the surface of the drive worm. The rotation of the cleaning disc is achieved through the cooperation of the worm and the worm wheel. The end of the drive worm is fixedly connected to the upper rotating shaft to achieve power transmission.

[0018] A further technical solution includes an inlet fixedly installed on the outer side of the upper tank, which communicates with the interior of the filter chamber to introduce water to be purified into the device. The inlet and outlet are arranged oppositely to each other, so that the water flow forms a reasonable flow path within the device. A drain pipe is fixedly connected to the lower end of the lower tank to discharge water containing dirt. A drain control valve and a drain outlet are fixedly connected to the end of the drain pipe. The drain control valve can control the opening and closing of the drain. Three sets of flow meters are provided between the outlet and the inlet. The flow meters can monitor the inlet and outlet flow rates in real time, providing data support for adaptive flow regulation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention discloses an adaptive flow-controlled self-draining pure water purification device. It features two scrapers (a second scraper and a first scraper) to effectively remove dirt from the surface of the filter cartridge. The second scraper, longer than the first, extends to the surface of the filter cartridge and has irregular textures at its front end for targeted scraping of stubborn dirt. The front end of the first scraper contacts the outer wall of the filter cartridge for further removal of residual dirt. A compression spring connecting both scrapers near the central protrusion ensures tight contact between the scrapers and the filter cartridge, enhancing scraping force and range. This achieves comprehensive removal of dirt of varying depths and stubbornness from the filter cartridge surface, avoiding the incomplete cleaning caused by a single scraper. This significantly improves the cleanliness of the filter cartridge, ensures stable filtration efficiency, and extends its service life. A stepped inclined guide plate guides the directional movement of dirt scraped by the scraper. The inclined guide plate connects between the second and first scrapers, with its end aligned with the rolling groove between the cleaning disc and the central protrusion, and is arranged in a stepped pattern from bottom to top.

[0021] This invention discloses an adaptive flow-controlled self-draining pure water purification device. It incorporates a crushing ball and a rolling groove. As the crushing ball rolls within the rolling groove, it contacts the second and first scrapers, repeatedly crushing the dirt within the groove with the help of the rotating cleaning disc. This crushing action compresses loose dirt into clumps, significantly reducing its volume and preventing it from being difficult to collect due to dispersion. This increases the aggregation degree of the dirt. For subsequent adsorption and discharge processes, the clumps of dirt are more easily captured by the adsorption force generated by the central drive component compared to loose dirt, reducing the amount of dirt dispersed with the water flow during adsorption and improving adsorption efficiency. Simultaneously, the clumps of dirt are less likely to clog the drain pipe when discharged, ensuring smooth drainage and reducing the frequency of pipe cleaning and maintenance.

[0022] This invention discloses an adaptive flow-controlled self-draining pure water purification device. It features a turbine rotating vane with a rectangular bend and wavy convex texture on the outer side. During rotation, the spiral suction force efficiently adsorbs dirt and surrounding water from the outside of the filter cartridge. This not only captures crushed dirt but also removes fine dirt particles scattered during cleaning, significantly improving the removal range and rate, and reducing dirt residue near the filter cartridge. Regarding water flow, the spiral suction force creates an orderly spiral flow, preventing localized stagnation and ensuring smoother circulation between the filtration and storage chambers. Simultaneously, this flow enhances the contact efficiency between the water and the filter cartridge, indirectly improving the filtration effect. From the perspective of overall device operation, the enhanced adsorption effect reduces dirt deposition inside the device, minimizing contamination and wear on the filter cartridge and other components, and extending the replacement cycle of parts.

The end of the drive worm gear 22 is fixedly connected to the upper rotating shaft 35 to realize the transmission of power.

[0054] Preferred options are shown in the appendix. Figure 1 To be continued Figure 3 An inlet 15 is fixedly installed on the outside of the upper tank 12. The inlet 15 is connected to the inside of the filter chamber 19 and is used to introduce water to be purified into the device. The inlet 15 is opposite to the outlet 18 so that the water flow forms a reasonable flow path in the device. A drain pipe 29 is fixedly connected to the lower end of the lower tank 11. The drain pipe 29 is used to discharge water containing dirt. A drain control valve 14 and a drain outlet 17 are fixedly connected to the end of the drain pipe 29. The drain control valve 14 can control the opening and closing of the drain. Three sets of flow meters 16 are provided between the outlet 18 and the inlet 15. The flow meters 16 can monitor the inlet and outlet flow in real time and provide data support for adaptive flow control.

[0055] Specific usage of this invention:

[0056] When using this equipment, first securely install it in a suitable location within the wastewater treatment plant, and accurately connect the equipment's inlet 15, outlet 18, and drain outlet 17 to the corresponding external pipes. Use sealing rings to reinforce the seal at the connection points to prevent water leakage from affecting the equipment's operation.

[0057] When water enters through inlet 15, it flows smoothly into the filter chamber 19. At this time, the drain valve of outlet 17 is closed, and the water inside the filter chamber 19 forms a closed loop. Under pressure, the water passes through filter cartridge 20 for filtration. Impurities and dirt in the water settle on the surface of filter cartridge 20, while the purified water is discharged through drain pipe 27 to outlet 18. The entire filtration process is efficient and stable.

[0058] As the equipment operates for extended periods, a significant amount of scale will accumulate on the surface of the filter cartridge 20. This continuous accumulation of scale leads to a gradual decrease in drainage volume. At this time, three sets of flow meters 16 located between the outlet 18 and the inlet 15 can accurately monitor water flow changes in real time. When the water flow is detected to have decreased to a preset threshold, the equipment will automatically activate the drive assembly 13. After the drive motor 23 starts, it drives the drive worm gear 22 to rotate. The rotation of the drive worm gear 22 engages with the gear grooves on the upper and lower sections of the spiral sleeve 40, thereby driving the cleaning assembly 21 to move up and down.

[0059] When the cleaning component 21 moves up and down, the extended steel brush 41 of the cleaning component 21 first makes close contact with the surface of the filter cartridge 20, performing comprehensive steel brush abrasion on the surface of the filter cartridge 20, effectively removing shallow dirt adhering to the surface and preparing for subsequent deep cleaning. Subsequently, as the drive worm 22 continues to rotate, the drive worm 22 cooperates with the spiral worm wheel located in the gap in the middle section of the spiral sleeve 40, driving the spiral worm wheel to rotate, which in turn drives the first drive gear disk 44 and the second drive gear disk 46 to rotate. After the first drive gear disk 44 and the second drive gear disk 46 rotate, they drive the drive gear ring 42 to rotate inside the cleaning box 39. The rotary bearing 43 on the outer side of the drive gear ring 42 effectively reduces the frictional resistance during rotation, ensuring smooth rotation.

[0060] As the drive gear ring 42 rotates, the scraping and cleaning device 53 also rotates, creating a deep scraping effect on the surface of the filter cartridge 20. When the cleaning disc 47 rotates as a whole, the second scraper 50 and the first scraper 49 continue to be in close contact with the surface of the filter cartridge 20 and scrape under the action of the compression spring 51. Because the front end of the second scraper 50 is longer than that of the first scraper 49, the extended portion of the second scraper 50 is tightly attached to the surface of the filter cartridge 20, and the irregular texture at its front end can effectively scrape and clean stubborn dirt on the surface of the filter cartridge 20. Meanwhile, the front end of the first scraper 49 contacts the outer wall of the filter cartridge 20, further removing residual dirt.

[0061] The dirt scraped off is propelled by the centrifugal force generated by the overall rotation of the cleaning disc 47, swinging onto the side wall of the first scraper 49. As the rotation time increases, the dirt gradually accumulates on the side wall and then smoothly slides into the rolling groove through the stepped inclined guide plates. At the same time, the crushing ball 52 rolls in the rolling groove with the rotation of the cleaning disc 47. During the rolling process, it comes into contact with the second scraper 50 and the first scraper 49, and under the push of the scrapers, it fully rolls and compresses the dirt in the rolling groove, crushing the dirt into powder, which is convenient for subsequent adsorption and discharge. The crushing effect is thorough and efficient.

[0062] During the cleaning process, the rotation of the drive worm 22 also drives the upper rotating shaft 35 to rotate, which in turn drives the first gear 34 to rotate, and the first gear 34 in turn drives the central drive component 36 to rotate. When the central drive component 36 rotates, the gear ring sleeve 38 meshes with the first gear 34 and the drive gear 25, thereby driving the gear ring sleeve 38 and the turbine rotating vane 37 to rotate. When the turbine rotating vane 37 rotates, the wavy convex texture on its outer side will generate a strong disturbance to the water above the central drive component 36, forming a spiral adsorption force, which comprehensively adsorbs the outer side of the filter cartridge 20, adsorbing the crushed dirt and the water containing dirt together.

[0063] The adsorbed water and dirt enter the storage cavity 28 through the filter holes on the surface of the base 32. The incoming water flow impacts the rotating blades 26, causing them to rotate and buffering the water flow. This allows the water containing dirt to flow freely within the storage cavity 28, facilitating the sedimentation of the dirt. Finally, by opening the drain control valve 14, the water containing dirt and the crushed dirt in the storage cavity 28 are discharged from the drain outlet 17 through the drain pipe 29, achieving a thorough cleaning and ensuring that the equipment maintains good filtration efficiency at all times.

[0064] The entire self-draining process is highly automated and requires no manual intervention. This not only saves a lot of labor costs but also removes dirt in a timely and efficient manner, ensuring the continuous and stable operation of the pure water purification device and greatly improving the service life of the equipment and the quality of purified water.

Many modifications and variations will be apparent to those skilled in the art.
