Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to an integrated water treatment equipment for tap water. Background Technology

[0002] The core objective of tap water treatment is to remove physical, chemical, and biological pollutants from raw water (from rivers, lakes, reservoirs, groundwater, etc.), including the removal of silt, algae, bacteria, viruses, heavy metals, and organic pollutants, so that it meets the prescribed drinking water hygiene standards. Environmental protection equipment refers to the machinery, products, and systems produced and manufactured to control environmental pollution and improve environmental quality. Its core objective is to prevent and control pollution and protect the environment. In other words, it purifies raw water into tap water that meets the standards. This process itself is a typical process of environmental pollution control and ecological security protection, which prevents polluted water sources from harming human health and the ecological environment.

[0003] When water sources (such as lakes and reservoirs) experience algal blooms or massive algal growth during summer or specific seasons, the water may contain large amounts of algae and zooplankton (such as copepods and rotifers). Alternatively, when using surface water or lightly polluted rivers as water sources, the water may contain small aquatic plants, leaf fibers, plastic fragments, etc. Existing hydraulic screens are used for pre-treatment filtration of raw water to solve the problems of algal clogging and fibrous impurities. The filtered water is then subjected to further water treatment such as chemical flocculation and fine filtration to obtain drinking water. However, when existing hydraulic screens become clogged, they require continuous rinsing of the top of the filter cartridge with filtered clean water, which wastes water resources and generates a large amount of wastewater. Furthermore, they do not thoroughly clean the attached long fibers, and impurities are prone to caking and entanglement on the inner wall of the screen over time, causing blockage. Frequent backwashing reduces water treatment efficiency and results in high operating and maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated water treatment device for tap water to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: Embodiments of the present invention provide an integrated water treatment device for tap water, the device comprising a water treatment tank, a filter element rotatably disposed within the water treatment tank, and a connecting pipe for connecting to a chemical flocculation treatment process; the device further comprises: The scraping component is located inside the filter component; The suction component, located between the water treatment tank and the filter component, provides cleaning suction force for the scraping component and the filter component; A compaction component is mounted on and opposite to the scraping component, and is used to elastically compact impurities on the filter surface of the filter component. The elastic limiting component is symmetrically arranged on the scraping component and adjacent to the scraping component. It is used to provide suction guide and limiting space for cleaning impurities on the filter surface when combined with the compaction component and the filter component. Mechanical vibration components are installed on the filter components and correspond one-to-one with elastic limiting components. They are used to control the elastic limiting components to provide local vibration force to the filter components. The scraping component is located between the top of the suction component and the filter component; the scraping component synchronously controls the compaction component and the elastic limiting component; the filter component synchronously controls the mechanical vibration component.

[0006] Furthermore, the water treatment tank is composed of a raw water storage tank, an inlet tank, and a filtration tank in sequence; A weir plate is installed between the raw water storage tank and the inlet tank to ensure that the tap water in the raw water storage tank enters the inlet tank at a uniform and stable speed. The depth of the filtration pool is greater than the depth of the inlet pool; the filtration component is installed inside the filtration pool and is connected to the inlet pool.

[0007] Furthermore, a front mounting plate is provided between the water inlet tank and the filter tank, a rear mounting plate is provided inside the filter tank, a first bracket is fixedly installed on the filter tank, and a water inlet hole for water intake is provided on the front mounting plate. The filter component includes: The rotating ring, with a sealed rotating arrangement, is mounted on the front mounting plate facing the filter tank and is coaxial with the water inlet hole; The motor bracket is fixedly mounted on the first bracket; The drive motor is fixedly mounted on the motor bracket; The drive shaft is rotatably mounted on the rear mounting plate; The filter cartridge is sealed and fixed at one end on the rotating ring, and fixed at the other end on the transmission shaft; The transmission shaft and the output shaft of the drive motor are connected by a transmission component; the filter cartridge, the rotating ring, and the transmission shaft are all coaxial; the opening diameter of the filter cartridge is smaller than the inner diameter of the rotating ring.

[0008] Furthermore, a second bracket is fixedly installed on the top of the inlet pool near the filter pool side, and the suction component includes: The suction mounting plate is fixedly installed at the bottom of the second bracket; The suction pipe is fixedly installed on the suction mounting plate and the water inlet tank; The suction bracket is fixedly installed on the outer wall of the inlet pool; The power source for vacuuming is fixedly installed on the vacuuming support and connected to the vacuuming pipe; The suction clearance channel is located at the top of the suction pipe and inside the filter cartridge; The suction pipe and the inner wall of the filter cartridge are rotatably connected and coaxially arranged; the scraping component is disposed on the suction pipe and is interconnected with the suction pipe through a suction clearance groove.

[0009] Furthermore, the scraping component includes: The positioning frame is scraped off, and the top is open. It is fixedly installed on the suction pipe and is connected to the suction clearance groove. Scrape off the drive frame, which is slidably positioned on the inner wall of the scraping positioning frame; An auxiliary positioning seat is fixedly installed on the inner wall of the scraping positioning frame; Install a blind clearance groove, which is located on the auxiliary positioning seat; The electric push rod is fixedly installed in the installation clearance blind groove, and the telescopic rod is sealed and slidably installed on the upper surface of the auxiliary positioning seat; The first elastic telescopic scraper is fixedly installed on the side wall of the scraping drive frame, which is parallel to the axis of the filter cartridge. The telescopic end of the electric push rod is fixedly installed at the bottom of the scraping drive frame; the top of the scraping drive frame is open, and the bottom is symmetrically provided with material discharge ports.

[0010] Furthermore, the compaction component includes: The compacted fixing frame is fixedly installed on the side wall of the scraping drive frame; The compaction movable plate is elastically slidably set on the compaction fixed frame; A fixed bracket is fixedly installed on the compaction movable plate on the side away from the compaction fixed frame; The pressure roller is rotatably mounted on a fixed support. When the drive motor is rotating clockwise, the pressure roller and the first elastic telescopic scraper are arranged clockwise.

[0011] Furthermore, the elastic limiting component includes: The side plate is fixedly installed on the side wall of the scraping drive frame, which is perpendicular to the axis of the filter cartridge in space. Several stop posts are evenly distributed on the side plate to provide an elastically adjustable closed connection between the side plate and the inner wall of the filter cartridge, and to provide vibration force to the inner wall of the filter cartridge. The ball bearings correspond one-to-one with the stop posts and are all movably embedded in the top of the stop posts; The stop posts are all elastically slidably mounted on the side plates; the mechanical vibration component is mounted on the inner wall of the filter cartridge and is located in the same vertical plane as the stop posts. When both the pressure roller and the first elastic telescopic scraper are in a state of no external force, the highest point of both the pressure roller and the first elastic telescopic scraper is located above the top of the side plate.

[0012] Furthermore, the mechanical vibration component includes: The vibration mounting ring is fixedly installed on the inner wall of the filter cartridge and is located on the same vertical plane as the side plate; Vibration protrusions, several of which are evenly distributed on the inner wall of the vibration mounting ring, are used to provide driving force for the vibration between the baffle column and the inner wall of the filter cartridge. The vibrating protrusion on the side furthest from the vibrating mounting ring is an arc-shaped surface, and the vibrating protrusion and the stop post are both on the same vertical plane.

[0013] Furthermore, a second elastic telescopic scraper is fixedly installed on the side plate located between the pressure roller and the first elastic telescopic scraper; When the second elastic telescopic scraper is in a state of no external force, the highest point of the second elastic telescopic scraper is also located above the top of the side plate.

[0014] The above-described solution of the present invention has at least the following beneficial effects: 1. The scraping component elastically fits the filter surface of the filter element, and the compaction component and elastic limiting component are also elastically fitted to the filter surface of the filter element simultaneously. The impurities on the filter surface of the filter element are first compacted by the compaction component before reaching the scraping component for scraping. This avoids consuming a large amount of filtered clean water, thus avoiding the waste of water resources and the generation of a large amount of wastewater. The scraping component removes the attached and entangled impurities, effectively preventing the impurities that are layered and entangled on the filter surface of the filter element from being scattered inside the filter element by the impact of dynamic water flow during the scraping process. The impurities on the filter surface after being processed by the compaction component are not immediately dispersed during scraping, making it easier to collect the scraped impurities and providing time for the suction component to collect them. The discharged filter cake is also simply compacted and dewatered, which effectively reduces the cost and difficulty of subsequent sludge treatment.

[0015] 2. The symmetrically arranged elastic limiting components, compaction components, and scraping components work together on the filter surface of the filter element, thereby providing a suction guiding and limiting space for cleaning impurities on the filter surface. In other words, the impurities on the filter surface generated by scraping are located within the space formed by the symmetrically arranged elastic limiting components, compaction components, and scraping components, effectively avoiding direct contact with the dynamic water flow and being scattered into the filter element by the impact of the dynamic water flow. This facilitates the concentrated suction treatment by the suction component, effectively providing a suction collection space for the suction component, that is, providing a suction channel.

[0016] 3. The filter element synchronously controls the mechanical vibration component, which in turn synchronously controls the elastic limiting component to provide local vibration force to the filter element. Under the combined action of the mechanical vibration component and the elastic limiting component, the impurities embedded in the filter element's filter surface, as well as those embedded in the filter element's filter surface due to the action of the compaction component, are loosened by corresponding local vibration. Since the elastic limiting component is located between the compaction component and the scraping component, the vibration area acts on the filter element between the compaction component and the scraping component. Thus, after the impurities embedded in the filter element's filter surface are loosened by vibration, under the combined action of the suction component and the scraping component, not only are the impurities on the filter element's filter surface scraped and cleaned, but the impurities embedded in the filter element's filter surface are also reverse-adsorbed and scraped away.

[0017] 4. This ensures continuous filtration while simultaneously resolving the issue of loosely attached and entangled filter impurities being dispersed again in the water flow during the scraping process. It effectively and promptly removes and cleans filter components and centrally absorbs impurities, effectively avoiding water waste and the generation of large amounts of wastewater. Furthermore, it reduces the probability of incomplete cleaning of attached long fibers leading to impurities caking and entanglement on the inner wall of the filter over time, further guaranteeing the continuous filtration and separation effect and efficiency of water treatment.

[0020] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0021] like Figures 1 to 10 As shown, an integrated water treatment device for tap water includes a water treatment tank, a filter element rotated within the water treatment tank, and a connecting pipe 22 for connecting to the chemical flocculation treatment process; the device also includes: The scraping component is located inside the filter component; The suction component, located between the water treatment tank and the filter component, provides cleaning suction force for the scraping component and the filter component; A compaction component is mounted on and opposite to the scraping component, and is used to elastically compact impurities on the filter surface of the filter component. The elastic limiting component is symmetrically arranged on the scraping component and adjacent to the scraping component. It is used to provide suction guide and limiting space for cleaning impurities on the filter surface when combined with the compaction component and the filter component. Mechanical vibration components are installed on the filter components and correspond one-to-one with elastic limiting components. They are used to control the elastic limiting components to provide local vibration force to the filter components. The scraping component is located between the top of the suction component and the filter component; the scraping component synchronously controls the compaction component and the elastic limiting component; the filter component synchronously controls the mechanical vibration component.

[0022] Specifically, the water treatment tank is composed of a raw water storage tank 1, an inlet tank 2, and a filtration tank 3 in sequence; A weir plate 4 is provided between the raw water storage tank 1 and the inlet tank 2 to ensure that the tap water in the raw water storage tank 1 enters the inlet tank 2 at a uniform and stable speed. The depth of the filter pool 3 is greater than the depth of the inlet pool 2; the filter component is installed inside the filter pool 3 and is connected to the inlet pool 2.

[0023] Furthermore, the device also includes a control unit for activating the scraping component and the suction component, the control unit comprising: Controller 6, located on the side wall of the water treatment tank, is used to control the start-up of the scraping and suction components; Water level detection component 5 is installed inside the inlet pool 2 and is electrically connected to the controller 6 for water level detection; It should be noted that the water level detection component 5 and controller 6 in this embodiment are existing products in the prior art. The water level detection component 5 and controller 6 mentioned in this embodiment are existing matching products selected from the market according to the usage needs and installation space requirements. We only use them and do not improve them. These products are equipped with corresponding instruction manuals and technical support. Therefore, in this embodiment, we only need to assemble them according to the instruction manual and technical support and then use them. The structural diagrams of the water level detection component 5 and controller 6 in the attached drawings are only for illustration. Therefore, the water level detection component 5 and controller 6 in this embodiment will not be described in detail. They only need to realize the purpose of detecting the water level to sense whether there is a problem of filter impurities clogging and controlling the start of the scraping component and the suction component. In this embodiment of the invention, the water level detection device 5 and the controller 6 are not specifically limited, but a hydrostatic level gauge is preferred; the controller 6 is a PLC control system. Thus, the water level detection element 5 is located inside the inlet pool 2. The higher the water level, the greater the pressure at the bottom. Since the water inlet pool 2 enters the filter pool 3 through the filter element, the tap water in the raw water storage pool 1 enters the inlet pool 2 at a uniform and stable speed. That is to say, when the filter element is blocked, the water level in the inlet pool 2 will rise. Then, the pressure sensor inside the water level detection element 5 will convert the pressure value it senses into a standard electrical signal. The electrical signal is then transmitted to the controller 6 through the cable. The controller 6 receives and processes the signal, makes logical judgments, and issues commands. When the water level rises to the set value, the controller 6 controls the scraping element and the suction element to start in sequence through the contactor. At this time, the filter element is still in working condition.

[0024] In practical application, raw water flows steadily and uniformly from the raw water storage tank 1 into the inlet tank 2 through the weir plate 4. The water to be filtered in the inlet tank 2 undergoes dynamic filtration through the filtration components and then enters the filtration tank 3. The water in the filtration tank 3 enters the chemical flocculation treatment process through the connecting pipe 22 for subsequent water treatment. When the water level detection device 5 detects that the water level in the inlet tank 2 has risen to the set value, the electrical signal connects to the controller 6, which controls the scraping component and the suction component to start sequentially via a contactor. At this time, the filtration components are still in working state, that is, the filtration components are still in dynamic filtration state. Subsequently, the scraping component elastically adheres to the filter surface of the filtration component, and simultaneously controls the compaction component and the elastic limiting component to also elastically adhere to the filter. The filter surface of the component is compacted by the compaction component before being scraped by the scraping component. This avoids wasting water resources by consuming a large amount of filtered clean water and generating a large amount of wastewater. The scraping component removes the attached and entangled impurities and effectively prevents the impurities that are attached and entangled on the filter surface from being scattered inside the filter by the dynamic water flow during the scraping process. The impurities on the filter surface after being processed by the compaction component are not immediately dispersed during the scraping process, making it easier to collect the scraped impurities and providing time for the suction component to collect them. The discharged filter cake is also simply compacted and dewatered, which effectively reduces the cost and difficulty of subsequent sludge treatment. Meanwhile, the symmetrically arranged elastic limiting components, compaction components, and scraping components work together on the filter surface of the filter element, providing a suction guide and limiting space for cleaning impurities on the filter surface. In other words, the symmetrically arranged elastic limiting components, compaction components, and scraping components form a circle. When the filter element is working, the impurities on the filter surface located between the compaction components and the scraping components are compacted by the compaction components and then scraped off by the scraping components. The impurities generated by the scraping are located within the space formed by the symmetrically arranged elastic limiting components, compaction components, and scraping components, effectively avoiding direct contact with the dynamic water flow and being scattered into the filter element by the impact of the dynamic water flow. This facilitates the concentrated suction of impurities by the suction component, effectively providing a suction collection space for the suction component, that is, providing a suction channel. During this process, the filter component synchronously controls the mechanical vibration component, which in turn synchronously controls the elastic limiting component to provide local vibration force to the filter component. Then, under the combined action of the mechanical vibration component and the elastic limiting component, the impurities embedded in the filter surface of the filter component, as well as the impurities embedded in the filter surface of the filter component due to the action of the compaction component, are loosened by corresponding local vibration. Since the elastic limiting component is located between the compaction component and the scraping component, the vibration area acts on the filter component between the compaction component and the scraping component. Thus, after the impurities embedded in the filter surface of the filter component are loosened by vibration, under the combined action of the suction component and the scraping component, the impurities on the filter surface of the filter component are not only scraped and cleaned, but the impurities embedded in the filter surface of the filter component are also reverse-adsorbed and scraped away. This ensures continuous filtration while simultaneously addressing the issue that loosely attached and entangled filter impurities are dispersed again in the water flow during the scraping process. It effectively and promptly removes and cleans the filter components, as well as centrally absorbs and treats impurities, thus avoiding the waste of water resources and the generation of large amounts of wastewater. Furthermore, it reduces the probability of incomplete cleaning of attached long fibers, which could lead to impurities caking and entanglement on the inner wall of the filter over time, causing blockages. This further guarantees the continuous filtration and separation effect and efficiency of water treatment.

[0025] In a preferred embodiment of the present invention, a front mounting plate 7 is provided between the water inlet tank 2 and the filter tank 3, a rear mounting plate 8 is provided inside the filter tank 3, a first bracket 9 is fixedly provided on the filter tank 3, and a water inlet hole for water intake is provided on the front mounting plate 7. The filter component includes: The rotating ring 10 is mounted on the front mounting plate 7 facing the filter tank 3 and is coaxial with the water inlet hole. The motor bracket is fixedly mounted on the first bracket 9; The drive motor 13 is fixedly mounted on the motor bracket; The transmission shaft 11 is rotatably mounted on the mounting rear plate 8; The filter cartridge 12 is fixedly mounted on the rotating ring 10 at one end and on the transmission shaft 11 at the other end. The transmission shaft 11 and the output shaft of the drive motor 13 are connected by a transmission component; the filter cartridge 12, the rotating ring 10, and the transmission shaft 11 are all coaxial; the opening diameter of the filter cartridge 12 is smaller than the inner diameter of the rotating ring 10.

[0026] Specifically, the transmission component described in this embodiment of the invention is not specifically limited and can be a belt pair or a chain pair, as long as it can realize the power transmission between the transmission shaft 11 and the drive motor 13.

[0027] In practical application, raw water enters the filter cartridge 12 through the inlet pool 2 and the inlet hole. At this time, the drive motor 13 is in operation. Under the combined action of the transmission components and the transmission shaft 11, the rotation of the drive motor 13 synchronously drives the filter cartridge 12 and the rotating ring 10 to maintain rotation. Then, the tap water entering the filter cartridge 12 undergoes impurity separation under its own gravity. The impurities adhere to the inner wall of the filter cartridge 12. The filtered tap water passes through the filter cartridge 12 and enters the filtration tank 3, and is discharged through the discharge pipe for subsequent disinfection treatment. The rotating filter cartridge 12 provides a dynamic filtration surface for tap water filtration, preventing all impurities from accumulating in one place on the inner wall of the filter cartridge 12. It also provides dynamic pulsation force to achieve dynamic water filtration, which further improves the filtration efficiency compared to relying solely on the gravity of the water flow to pass through the filter cartridge 12.

[0028] In a preferred embodiment of the present invention, a second support 14 is fixedly installed on the top of the inlet pool 2 near the filter pool 3, and the suction component includes: The suction mounting plate 15 is fixedly installed at the bottom of the second bracket 14; The suction pipe 16 is fixedly installed on the suction mounting plate 15 and the water inlet pool 2; A suction bracket is fixedly installed on the outer wall of the inlet pool 2; The sewage suction power source 17 is fixedly installed on the sewage suction bracket and is connected to the sewage suction pipe 16; The suction clearance groove 18 is located at the top of the suction pipe 16 and inside the filter cartridge 12; The suction pipe 16 and the inner wall of the filter cartridge 12 are rotatably connected and are coaxially arranged; the scraping component is disposed on the suction pipe 16 and is interconnected with the suction pipe 16 through the suction clearance groove 18.

[0029] Specifically, the suction power source 17 is not specifically limited. In the preferred embodiment of the present invention, the suction power source 17 is a dual-purpose dry and wet vacuum cleaner, which provides strong suction and the ability to handle dry and wet materials.

[0030] It should be noted that the wet and dry vacuum cleaner components described in this disclosure are all existing products in the prior art. The wet and dry vacuum cleaner components mentioned in this disclosure are all existing matching products selected from the market according to usage needs and installation space requirements. We are only using them and have not improved them. These products are all equipped with corresponding instruction manuals and technical support. Therefore, in this disclosure, we only need to complete the assembly according to the instruction manual and technical support before using them. The structural diagram of the wet and dry vacuum cleaner component in the attached drawings is only for illustration. Therefore, the wet and dry vacuum cleaner component in this disclosure will not be described in detail. It is only necessary to achieve the purpose of adsorbing and removing the impurities scraped by the scraping component.

[0031] In practical application, when the water level detection device 5 detects that the water level in the inlet tank 2 has risen to the set value, the electrical signal connects the controller 6 to control the scraping component and the suction power source 17 to start sequentially via a contactor. At this time, the water inlet is still in the water intake state, and the drive motor 13 is still in the working state. That is to say, when the scraping component is in the state of scraping impurities from the inner wall of the filter cartridge 12, the suction power source 17 starts synchronously to adsorb and remove the impurities scraped by the scraping component. Then, during the rotation of the filter cartridge 12, it can both filter the tap water after flocculation and sedimentation and simultaneously achieve the function of the scraping component. The current impurity scraping and cleaning system continuously maintains the filtration function of the filter cartridge 12, ensuring its filtration effect and efficiency. At the same time, the suction power source 17 promptly adsorbs and cleans the impurities scraped by the scraping component, avoiding the dispersion of scraped impurities and the accumulation of impurities after long-term operation. Under the combined action of the scraping component, compaction component, elastic limiting component, and mechanical vibration component, the filter cartridge 12 can be further cleaned by reverse adsorption, removing the impurities embedded in the filter cartridge 12. This further improves the separation and filtration efficiency and continuous filtration effect, realizing the self-cleaning of the filter cartridge 12 and reducing water waste.

[0032] In a preferred embodiment of the present invention, the scraping component includes: The scraping positioning frame 20 is set with an open top, fixedly installed on the suction pipe 16, and connected to the suction clearance groove 18. The scraping drive frame 21 is slidably set on the inner wall of the scraping positioning frame 20; Auxiliary positioning seat 24 is fixedly installed on the inner wall of scraping positioning frame 20; Install a blind clearance slot, which is provided on the auxiliary positioning seat 24; The electric push rod 19 is fixedly installed in the installation clearance blind groove, and the telescopic rod is sealed and slidably installed on the upper surface of the auxiliary positioning seat 24 to provide driving force for the lifting and lowering of the scraping drive frame 21; The first elastic telescopic scraper 28 is fixedly installed on the side wall of the scraping drive frame 21, which is parallel to the axis of the filter cartridge 12. The telescopic end of the electric push rod 19 is fixedly disposed at the bottom of the scraping drive frame 21; the top of the scraping drive frame 21 is open, and the bottom is symmetrically provided with material discharge ports; the compaction component is disposed on the other side wall of the scraping drive frame 21 parallel to the axial direction of the filter cylinder 12; the elastic limiting component is symmetrically disposed on the other side wall of the scraping drive frame 21 perpendicular to each other in space in the axial direction of the filter cylinder 12. When the electric push rod 19 is at its maximum stroke position, the scraping drive frame 21 and the scraping positioning frame 20 are at their maximum relative distance position.

[0033] Furthermore, to prevent scraped impurities from falling into the suction pipe 16 due to the inner wall of the bottom of the scraping drive frame 21, and to prevent scraped impurities from falling completely from the discharge port into the suction pipe 16, a triangular anti-drop block is provided on the inner wall of the bottom of the scraping drive frame 21, thereby preventing scraped impurities from accumulating on the inner wall of the bottom of the scraping drive frame 21.

[0034] In practical application, when the water level detection device 5 detects that the water level in the inlet pool 2 has risen to the set value, the electrical signal connected controller 6 controls the electric push rod 19 and the suction power source 17 to start sequentially via a contactor. At this time, the electric push rod 19 is at its minimum stroke position. After the electric push rod 19 starts, it drives the scraping drive frame 21 to slide upward along the inner wall of the scraping positioning frame 20. Then, the scraping drive frame 21 drives the symmetrically arranged elastic limiting component, compaction component, and first elastic telescopic scraper 28 to elastically act on the inner wall of the filter cylinder 12 used for filtering impurities. Thus, during the rotation of the filter cylinder 12, the compaction component elastically compacts the impurities on the inner wall of the filter surface of the filter cylinder 12. The first elastic telescopic scraper 28 then follows to scrape away the impurities that have been compacted on the inner wall of the filter cylinder 12 to ensure the filtration effect of the filter cylinder 12. The compaction component also avoids scraping up the impurities on the inner wall of the filter cylinder 12 and scattering them inside the filter cylinder 12 after being directly acted upon by the water flow. Instead, it first uses the compaction component to remove the impurities. The solid component first compacts the impurities at this location. Then, the compacted impurities enter between the compaction component and the first elastic telescopic scraper 28. As the filter cylinder 12 rotates, the first elastic telescopic scraper 28 scrapes up the previously compacted impurities to clean the impurities on the filter cylinder 12. The compacted impurities scraped up by the first elastic telescopic scraper 28 fall into the space formed by the compaction component, the first elastic telescopic scraper 28, and the symmetrically arranged elastic limiting components. This space is connected to the top of the scraping drive frame 21. Therefore, the compacted impurities scraped up by the first elastic telescopic scraper 28 will not directly contact the dynamic water flow, but will be collected in the space formed by the compaction component, the first elastic telescopic scraper 28, and the symmetrically arranged elastic limiting components. Then, they pass through the scraping drive frame 21 and the discharge port into the suction pipe 16. During this process, the suction power source 17 is working simultaneously to provide suction force, which further sucks the scraped compacted impurities into the suction pipe 16 and discharges the sucked impurities.

[0035] In a preferred embodiment of the present invention, the compaction component includes: The compaction and fixing frame 29 is fixedly installed on the side wall of the scraping drive frame 21 on the side away from the first elastic telescopic scraper 28; The compaction movable plate 30 is elastically slidably mounted on the compaction fixed frame 29; A fixed bracket is fixedly installed on the compaction movable plate 30 on the side away from the compaction fixed frame 29; The pressure roller 31 is rotatably mounted on the fixed bracket; When the drive motor 13 is rotating clockwise, the pressure roller 31 and the first elastic telescopic scraper 28 are arranged clockwise.

[0036] Specifically, the sliding connection between the compaction movable plate 30 and the compaction fixed frame 29 is elastically connected by a spring, thereby enabling the compaction movable plate 30 to elastically slide on the compaction fixed frame 29.

[0037] like Figure 9 As shown, several sets of springs are evenly arranged between the inner walls of the compaction movable plate 30 and the compaction fixed frame 29. One end of each spring is fixed to the inner wall of the compaction fixed frame 29, and the other end is fixed to the bottom of the compaction movable plate 30 located inside the compaction fixed frame 29. In this embodiment, nine sets of springs are preferably evenly distributed at the sliding connection between the compaction movable plate 30 and the compaction fixed frame 29. When the compaction fixed frame 29 drives the compaction movable plate 30 and the pressure roller 31 to move towards the inner wall of the filter cylinder 12 and act on the inner wall of the filter cylinder 12, the springs between the compaction movable plate 30 and the compaction fixed frame 29 are in a compressed state. That is to say, the pressure roller 31 is elastically pressed against the inner wall of the filter cylinder 12. This avoids the pressure roller 31 being rigidly squeezed against the inner wall of the filter cylinder 12, and at the same time provides an elastically adjustable and uniform holding force for the impurities on the inner wall of the filter cylinder 12, solving the problem that impurities are easily scattered when scraped. The magnitude of this holding force (that is, the selection of springs) is adjusted and selected according to the actual application requirements.

[0038] In practical application, when the drive motor 13 is rotating clockwise, the pressure roller 31 and the first elastic telescopic scraper 28 are arranged clockwise. When the scraping drive frame 21 drives the symmetrically arranged elastic limiting components, pressure roller 31, and first elastic telescopic scraper 28 to elastically act on the inner wall of the filter cylinder 12 used for filtering impurities, the pressure roller 31 elastically presses against the inner wall of the filter cylinder 12. Then, during the rotation of the filter cylinder 12, the pressure roller 31 will first gradually flatten and compact the impurities passing through it, and can also process impurities that are attached to uneven surfaces, effectively preventing a large amount of impurities from adhering to a certain area. When scraping away impurities, direct scraping may cause clogging. After being processed by the pressure roller 31, the impurities move with the rotation of the filter cylinder 12 to the first elastic telescopic scraper 28 for scraping. At this time, the pressure roller 31, the first elastic telescopic scraper 28, and the symmetrically arranged elastic limiting components work together on the inner wall of the filter cylinder 12. Subsequently, the pressure roller 31, the first elastic telescopic scraper 28, and the symmetrically arranged elastic limiting components form an impurity collection space, which prevents the scraped impurities from directly contacting the flowing water and scattering into the filter cylinder 12, and facilitates the collection of the scraped impurities.

[0039] In a preferred embodiment of the present invention, the elastic limiting component includes: Side plate 32 is fixedly mounted on the side wall of scraping drive frame 21, which is perpendicular to the axis of filter cartridge 12 in space. The stop posts 33 are evenly distributed on the side plate 32 to provide an elastic adjustable closed connection between the side plate 32 and the inner wall of the filter cartridge 12 and to provide vibration force to the inner wall of the filter cartridge 12. The ball bearings correspond one-to-one with the stop post 33 and are all movably embedded in the top of the stop post 33; The stop posts 33 are all elastically slidably disposed on the side plate 32; the mechanical vibration component is disposed on the inner wall of the filter cartridge 12 and is located on the same vertical plane as the stop posts 33. When both the pressure roller 31 and the first elastic telescopic scraper 28 are in a state of no external force, the highest point of both the pressure roller 31 and the first elastic telescopic scraper 28 is located above the top of the side plate 32.

[0040] Specifically, the sliding connection between the stop post 33 and the side plate 32 is elastically connected by a spring, thereby enabling the stop post 33 to slide elastically on the side plate 32.

[0041] like Figure 10 As shown, the side plate 32 is provided with a second elastic slide groove corresponding to the stop post 33. The stop post 33 is slidably disposed in the second elastic slide groove. A spring is provided between the stop post 33 and the inner wall of the second elastic slide groove. One end of the spring located between the stop post 33 and the inner wall of the second elastic slide groove is fixedly disposed in the inner wall of the second elastic slide groove, and the other end is fixedly connected to the end of the stop post 33 located in the second elastic slide groove. In this embodiment, a set of springs is preferably provided at the sliding connection between the stop post 33 and the inner wall of the second elastic groove. When the mechanical vibration component acts on the ball and the stop post 33, the spring at the sliding connection between the stop post 33 and the inner wall of the second elastic groove is in a compressed and stored state. Then, when there is no interaction force between the mechanical vibration component and the ball and the stop post 33, under the action of the spring's rebound force, the stop post 33 drives the ball to elastically impact the inner wall of the filter cylinder 12, thereby generating a vibration force on the inner wall of the filter cylinder 12.

[0042] More specifically, the number of stop pins 33 is not specifically limited. It can be set according to the actual application, as long as it can provide an elastically adjustable closed connection between the side plate 32 and the inner wall of the filter cartridge 12 and provide vibration force to the inner wall of the filter cartridge 12, and when the electric push rod 19 is at its maximum stroke position, that is, when the scraping drive frame 21 moves to the highest position, it can maintain the closing effect between the side plate 32 and the inner wall of the filter cartridge 12 to the greatest extent.

[0043] In practical application, since the inner wall of the filter cartridge 12 is an arc surface, several stop posts 33 and ball bearings movably embedded in the top of the stop posts 33 are elastically slidably arranged on the side plate 32 facing the filter cartridge 12. Therefore, there is no need to further limit the upper surface of the side plate 32. That is, the upper surface of the side plate 32 can be an arc surface with the same diameter as the inner wall of the filter cartridge 12, or it can be a non-arc surface with the same diameter as the inner wall of the filter cartridge 12. In this embodiment, it is preferred that the upper surface of the side plate 32 be an arc surface with the same diameter as the inner wall of the filter cartridge 12. During the upward movement of the side plate 32 following the scraping drive frame 21, the pressure roller 31 and the first elastic telescopic scraper 28 first touch the inner wall of the filter cartridge 12. Subsequently, each ball bearing preferentially acts on the inner wall of the filter cartridge 12, thereby driving the corresponding stop posts 33 to elastically slide on the side plate 32. Inside, several baffles 33 provide an elastically adjustable closed connection between the side plate 32 and the inner wall of the filter cylinder 12. That is, the combination of the symmetrically arranged side plate 32 and several evenly arranged baffles 33, together with the pressure roller 31 and the first elastic telescopic scraper 28, after elastically fitting the inner wall of the filter cylinder 12, forms a space independent of the filter cylinder 12. This is to prevent the dynamic water flow from directly acting on the scraped impurities and to maximize the suction effect of the suction power source 17. During this process, the filter cylinder 12 synchronously controls the mechanical vibration components to act on the balls and baffles 33. Then, the balls and baffles 33 synchronously provide vibration force to the inner wall of the filter cylinder 12, thereby vibrating and loosening the impurities embedded in the filter surface of the inner wall of the filter cylinder 12. It should be noted that, in combination Figures 5 to 7 It is known that the vibration of the filter cylinder 12 inner wall by the several baffles 33 and the ball bearings is a local effect, only within the area corresponding to the side plate 32. That is, the combination of the symmetrically arranged side plate 32 and the several evenly arranged baffles 33, together with the pressure roller 31 and the first elastic telescopic scraper 28, after elastically adhering to the inner wall of the filter cylinder 12, forms a space independent of the filter cylinder 12. It is only effective in the vicinity of this space. The vibration effect is to immediately loosen the adhesion between the impurities in this space and the inner wall of the filter cylinder 12, so that the first elastic telescopic scraper 28 can remove impurities more cleanly with less scraping force. Because the vibration range is extremely small and the vibration energy decays rapidly in the inner wall of the filter cylinder 12 and in the water, it does not produce any substantial interference to the water flow field and impurity settling process in the main filtration settling zone far from the position of the first elastic telescopic scraper 28. In other words, most of the filter cylinder 12 area is still in an ideal static settling environment for most of the time.

[0044] In a preferred embodiment of the present invention, the mechanical vibration component includes: The vibration mounting ring 34 is fixedly installed on the inner wall of the filter cartridge 12 and is located on the same vertical plane as the side plate 32; Vibration protrusions 35 are evenly distributed on the inner wall of vibration mounting ring 34 to provide driving force for vibration between baffle post 33 and inner wall of filter cartridge 12. The side of the vibration protrusion 35 away from the vibration mounting ring 34 is curved, and the vibration protrusion 35 and the stop post 33 are both on the same vertical plane.

[0045] Specifically, the vibration protrusion 35 can be a protrusion of different sizes, as long as the vibration protrusion 35 can drive the ball and the stop post 33 to move elastically along the side plate 32 during rotation.

[0046] Furthermore, in order to better address the impurities embedded in the inner wall of the filter cylinder 12 and to compact the impurities embedded in the inner wall of the filter cylinder 12, a second elastic telescopic scraper 36 is fixedly installed on the side plate 32 located between the pressure roller 31 and the first elastic telescopic scraper 28. When the second elastic telescopic scraper 36 is in a state without external force, the highest point of the second elastic telescopic scraper 36 is also located above the top of the side plate 32.

[0047] In practical application, this embodiment utilizes a vibrating mounting ring 34 fixedly mounted on the inner wall of the filter cylinder 12, and several vibrating protrusions 35 evenly distributed on the inner wall of the vibrating mounting ring 34. The vibrating protrusions 35 and the stop posts 33 are all on the same vertical plane. As the filter cylinder 12 rotates, it drives the vibrating mounting ring 34 and the vibrating protrusions 35 to rotate synchronously. When the symmetrically arranged side plates 32, the several evenly distributed stop posts 33, and the ball bearings combine with the pressure roller 31 and the first elastic telescopic scraper 28, they elastically adhere to the inner wall of the filter cylinder 12. Behind the wall, each vibrating protrusion 35 acts on the ball bearings and the stop post 33 during rotation. Since the stop posts 33 are elastically slidably mounted on the side plate 32, after the ball bearings lose the effect of the vibrating protrusions 35, the spring rebound force causes the stop posts 33 to drive the corresponding ball bearings to impact the vibrating mounting ring 34. Subsequently, the vibration force is transmitted to the inner wall of the filter cartridge 12. Thus, each stop post 33 drives the corresponding ball bearings to impact the vibrating mounting ring 34, generating vibration on the inner wall of the filter cartridge 12 in a cyclical manner, thereby vibrating the inner wall of the filter cartridge 12. The impurities embedded in the inner wall of the filter cylinder 12 are loosened by local vibration to facilitate scraping and adsorption from the inner wall of the filter cylinder 12; in addition, by fixing a second elastic telescopic scraper 36 on the side plate 32 located between the pressure roller 31 and the first elastic telescopic scraper 28, double scraping is achieved. After the second elastic telescopic scraper 36 scrapes away the compacted impurities for the first time, this part of the inner wall of the filter cylinder 12 moves between the first elastic telescopic scraper 28 and the second elastic telescopic scraper 36. Due to the movement of each stop post 33, the impurities are loosened by local vibration. The corresponding ball bearings impact the vibrating mounting ring 34, which repeatedly vibrates the inner wall of the filter cartridge 12. This allows the vibration force to act more fully on the impurities embedded in the inner wall of the filter cartridge 12, located between the first elastic telescopic scraper 28 and the second elastic telescopic scraper 36. The vibration loosens the impurities embedded in the inner wall of the filter cartridge 12, making it easier for the first elastic telescopic scraper 28 to scrape them a second time and for them to be adsorbed and removed from the inner wall of the filter cartridge 12. This facilitates the cleaning of impurities on the inner wall of the filter cartridge 12, ensuring the filtration effect and filtration efficiency of the filter cartridge 12. After the tap water filtration of the filter cartridge 12 is completed and the speed returns to normal, the electric push rod 19 resets from the maximum stroke position to the minimum stroke position, and then drives the scraping drive frame 21 to move down along the inner wall of the scraping positioning frame 20, thereby moving the ball, pressure roller 31, first elastic telescopic scraper 28 and second elastic telescopic scraper 36 away from the inner wall of the filter cartridge 12, so as to avoid interfering with the filtration function of the filter cartridge 12 and realize the all-round tap water filtration treatment of the filter cartridge 12.

[0048] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
