Description

Technical Field

[0001] This application relates to the field of water purification, and in particular to a multi-element alloy scale-inhibiting and antibacterial water purification device. Background Technology

[0002] Industrial water requires purification treatment, typically achieved through an internal core. The multi-element alloy within the core forms a micro-battery system, polarizing water molecules and generating "water dipoles" and "free electrons." This alters the binding environment of ions such as calcium and magnesium ions with acid radicals, disrupting the crystallization process and preventing scale formation. The polarized water dipoles deposit an ion-coupled layer on the pipe wall surface, isolating the metal pipe wall from the fluid and providing scale inhibition and antibacterial protection. The micro-current generated by the alloy is higher than the biocurrent of bacterial and algal cells, interfering with their division and metabolism, inhibiting enzyme activity, and achieving sterilization, algae removal, and prevention of biological contamination.

[0003] The inner core, as described in patent document CN2017105763370, can be composed of perforated anti-scaling plates. However, this structure has certain limitations: if the gaps between the anti-scaling plates are too large, the water treatment effect decreases; if the gaps are too small, dirt easily adheres or causes blockage. To improve the purification effect, related technologies have adopted inner cores with a sponge-like honeycomb structure, which enhances the purification effect by increasing the contact area. However, regardless of the structure, the inner core still needs to have tiny gaps for water flow, and it still faces the risk of blockage during long-term operation. The risk of blockage can be complete blockage or partial blockage, making the tiny gaps even smaller. Either type of blockage will lead to a decrease in the efficiency and effect of water purification.

[0004] Although some technical solutions remove impurities by adding a filtration step before purification, the fine particles remaining in the filtered water will still gradually adhere to or accumulate in the inner core during long-term operation. This is especially true when the inner core has a complex porous structure such as a honeycomb, making it extremely difficult to clean after clogging. Summary of the Invention

[0005] To address the problem of difficulty in cleaning clogged inner cores, this application provides a multi-alloy scale-inhibiting and antibacterial water purification device.

[0006] The multi-alloy scale-inhibiting and antibacterial water purification device provided in this application adopts the following technical solution: A multi-alloy scale-inhibiting and antibacterial water purification device includes: a water purification main body configured as a treatment chamber for fluid flow; a scale-inhibiting and antibacterial filter element assembly disposed within the treatment chamber; a first connecting mechanism, a second connecting mechanism, and multiple alloy metal wires connected between the two; and a driving mechanism for switching the second connecting mechanism between a filtration station and a cleaning station; wherein, in the filtration station, the second connecting mechanism is close to the first connecting mechanism, and the multiple alloy metal wires are close to each other and spirally stacked to form a dense porous filtration structure; in the cleaning station, the second connecting mechanism is separated from the first connecting mechanism, and the multiple alloy metal wires are stretched and de-stacking to form a loose linear gap structure; the alloy metal wires include at least copper, zinc, and nickel.

[0007] By adopting the above technical solution, the scale-inhibiting and antibacterial filter element assembly switches between the filtration and cleaning stages. In the filtration stage, the alloy metal wires form a dense, porous structure to purify the water normally, functioning the same as a regular purification filter element. In the cleaning stage, the metal wires are stretched and de-stacking to create loose gaps, making it easier for contaminants to detach and facilitating cleaning of the alloy metal wires, increasing service life and reducing the risk of clogging. This achieves both better water purification and better cleaning results.

[0008] Furthermore, both the first connecting mechanism and the second connecting mechanism have a central region, a side region, and an intermediate region located between the central region and the side region; the two ends of the plurality of alloy metal wires are respectively connected to the intermediate region of the first connecting mechanism and the intermediate region of the second connecting mechanism.

[0009] Furthermore, mounting holes are provided in the central region of the first connecting mechanism and / or the central region of the second connecting mechanism; a cleaning mechanism is provided at the mounting holes; the driving mechanism also directly or indirectly moves the cleaning mechanism between the first connecting mechanism and the second connecting mechanism and drives the cleaning mechanism to move outside the first connecting mechanism and the second connecting mechanism; the cleaning mechanism directly or indirectly contacts the alloy metal wire located at the cleaning station.

[0010] Furthermore, an installation body is provided on the outside of the water purification body, and the installation body has an installation chamber that is connected to the treatment chamber; during the cleaning station, the first connecting mechanism is located in the installation chamber, and the second connecting mechanism is fixed to the inner wall of the treatment chamber.

[0011] Furthermore, the cleaning mechanism includes: a water injection pipe and a water injection pump; the water injection pipe passes through the through hole; the water injection pump directly or indirectly connects the water injection pipe to the clean water in the treatment chamber; the water injection pipe is disposed in the installation chamber, and multiple oblique holes are opened on the water injection pipe, the oblique holes are at least axially inclined relative to the axis of the water injection pipe and the outlet of the oblique holes intersects with the alloy metal wire.

[0012] Furthermore, the water injection pipe is at least rotatably fitted with the mounting chamber, and the oblique hole is at least radially inclined relative to the axis of the water injection pipe, with the outlet of the oblique hole facing away from the axis of the water injection pipe; when the water injection pipe drains water outward, the water flowing through the oblique hole exerts an external force on the water injection pipe, causing the water injection pipe to have a rotational tendency.

[0013] Furthermore, a soft cleaning body is also provided on the water injection pipe; at the cleaning station, the middle or upper part of the soft cleaning body contacts the alloy metal wire; at the filtration station, both the soft cleaning body and the water injection pipe are located outside the first connecting mechanism and the second connecting mechanism; between the cleaning station and the filtration station, the end of the soft cleaning body is located outside the multiple alloy metal wires, so that the soft cleaning body contacts the multiple alloy metal wires.

[0014] Furthermore, the soft cleaning body is elastic, and an expansion chamber is formed within the soft cleaning body; the soft cleaning body is directly or indirectly connected to the water injection pipe; the soft cleaning body is also provided with multiple overflow holes, and the overflow holes are connected to the expansion chamber.

[0015] Furthermore, the alloy metal wire is provided with a plurality of protrusions, the diameter of which is larger than the diameter of the alloy metal wire.

[0016] Furthermore, the mounting holes are only located in the central region of the first connecting mechanism.

[0017] In summary, this application includes at least one of the following beneficial technical effects: When the scale-inhibiting and antibacterial filter element is in the filtration stage, the alloy metal wires form a dense porous structure to purify the water. In the cleaning stage, the metal wires are stretched and de-stacking to form loose gaps, making it easier for pollutants to fall off and for the alloy metal wires to be cleaned, thus increasing service life and reducing the risk of clogging.

[0018] The angled nozzles of the water injection pipe can penetrate deep into the gaps between the wires to flush them, and together with the soft cleaning body, it can physically clean the surface of the metal wires, improving the efficiency of removing adhesive dirt.

[0019] The inclined hole setting incorporates circumferential and tangential force components, which can utilize the reaction force to drive the water injection pipe to rotate, allowing the spray to cover different areas, reducing cleaning dead zones, and improving cleaning uniformity.

[0020] The alloy metal wires are designed with protrusions to form point contact when stacked and pressed together, avoiding large-area adhesion that would result in too small a pore size, making it difficult for water to flow. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-17 This application will be described in further detail.

[0024] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0025] This embodiment provides a multi-alloy scale inhibitor and antibacterial water purification device, which is mainly used in industrial circulating water treatment scenarios.

[0026] Reference Figures 1-2 The multi-alloy scale-inhibiting and antibacterial water purification equipment includes a water purification body 1, a scale-inhibiting and antibacterial filter element assembly 3, a drive mechanism 4, and a cleaning mechanism 5. In this embodiment, the water purification body 1 is mounted on a support platform 9, and a corresponding control cabinet, a corresponding control system, or a corresponding water storage tank can be installed on the support platform 9.

[0027] The water purification body 1 has a treatment chamber 11 for fluid flow. The water purification body 1 is tubular or tank-shaped, with an inlet 12 and an outlet 13. The scale-inhibiting and antibacterial filter element assembly 3 is disposed in the treatment chamber 11, with the inlet 12 located above the scale-inhibiting and antibacterial filter element assembly 3 and the outlet 13 located below the scale-inhibiting and antibacterial filter element assembly 3, so that water flows through the scale-inhibiting and antibacterial filter element assembly 3 for purification treatment.

[0028] Reference Figure 3 The scale-inhibiting and antibacterial filter element assembly 3 includes: a first connecting mechanism 31, a second connecting mechanism 32, and an alloy metal wire 33. The driving mechanism 4 is used to move the first connecting mechanism 31 and the second connecting mechanism 32 closer together and further apart within the processing chamber 11, switching between the filtration station and the cleaning station. Both the first connecting mechanism 31 and the second connecting mechanism 32 are movable, or one of them is movable.

[0029] The alloy metal wire 33 is connected between the first connecting mechanism 31 and the second connecting mechanism 32. The alloy metal wire 33 is made of a multi-element alloy material, containing multiple metallic elements such as copper, zinc, and nickel (additional elements include Ag, Al, Sn, Si, Bi, Sb, and Re, and at least one or more combinations can be selected). Utilizing the potential difference between different metallic elements, when water flows through, the polarity of the water dipoles in the water is enhanced, changing the binding field of scale-forming ions and making them less likely to bind, thus inhibiting scale formation. For existing scale, the water dipoles break its lattice bonds, causing it to gradually loosen and dissolve into the water, thus removing scale. Simultaneously, the multi-element alloy material also has anti-corrosion, antibacterial, and anti-wax properties, while also inhibiting scale formation and bacteria. In this embodiment, the material of the alloy metal wire 33 may only include copper, zinc, and nickel (e.g., Cu: 55%, Zn: 20%, Ni: 25%). When using more elements, the following ratio can be used: Cu: 26%, Ag: 26%, Zn: 9%, Al: 11%, Ni: 15%, Sn: 4%, Si: 3%, Bi: 4%, Sb: 1%, Re: 1%.

[0030] The first connecting mechanism 31 and the second connecting mechanism 32 are located at the filtration station. The second connecting mechanism 32 is close to the first connecting mechanism 31, and multiple alloy metal wires 33 are close to each other and spirally stacked to form a dense porous filtration structure. Reference Figure 1-3 14. The first connecting mechanism 31 and the second connecting mechanism 32 are located at the cleaning station. The second connecting mechanism 32 is separated from the first connecting mechanism 31. Multiple alloy metal wires 33 are stretched and unstacked to form a loose line gap structure.

[0031] Specifically, the multi-alloy scale-inhibiting and antibacterial water purification equipment also includes an installation body 2. The installation body 2 can be fixedly installed on the exterior of the water purification body 1, such as on the side wall. The installation body 2 has an installation chamber 21 inside, which communicates with the treatment chamber 11, forming a T-shaped or Y-shaped branch structure. The installation body 2 can be a side-mounted short cylinder, a side-mounted box, or a maintenance compartment structure. The installation chamber 21 inside the installation body 2 is used to accommodate the movable parts of the filter element assembly, arrange the cleaning mechanism 5, and provide space for the switching position of the first connecting mechanism 31 and the second connecting mechanism 32. The installation body 2 and the water purification body 1 can be connected by welding, flanges, threads, or clamps.

[0032] Reference Figure 6-7 In this embodiment, the first implementation of the drive mechanism 4 is as follows: The drive mechanism 4 can be located inside or outside the mounting body 2, ensuring that it can drive the first connecting mechanism 31 within the mounting body 2. The drive mechanism 4 is connected to the first connecting mechanism 31 via a transmission mechanism: the drive mechanism 4 can only move the first connecting mechanism 31 and the second connecting mechanism 32 closer together or further apart, thus causing the metal wires to be spirally stacked at the filtration station. The alloy metal wires 33 are elastic; when the first connecting mechanism 31 and the second connecting mechanism 32 are separated, the alloy metal wires 33 are stretched, approaching a straight line or partially bent, simply increasing the gap between the multiple alloy metal wires 33. When the first connecting mechanism 31 and the second connecting mechanism 32 are close together, the alloy metal wires 33 return to their spirally stacked state under their own elasticity. The alloy metal wires 33 can be weakly elastic spring wires.

[0033] Reference Figure 3 In this embodiment, the second implementation of the drive mechanism 4 is as follows: Reference Figure 9-11 The alloy metal wire 33 is not elastic. The driving mechanism 4 is connected to the first connecting mechanism 31 through a transmission. The driving mechanism 4 can also cause the first connecting mechanism 31 and the second connecting mechanism 32 to rotate relative to each other at a certain angle while they are close to or far apart, so that the metal wires are in a spiral stacked state at the filtration station.

[0034] The drive mechanism 4 can be a combination of a cylinder, a hydraulic cylinder, a linear motor, and a rotary motor. For example, the rotary motor drives the cylinder, hydraulic cylinder, or linear motor to rotate. The cylinder, hydraulic cylinder, or linear motor is connected to the first connecting mechanism 31 and can drive the first connecting mechanism to rotate. The cylinder, hydraulic cylinder, or linear motor is used to drive the first connecting mechanism 31 to move. This realizes the movement and rotation of the first connecting mechanism 31.

[0035] Reference Figure 10 The process by which the drive mechanism 4 switches the first connecting mechanism 31 to the filtration station is as follows: the drive mechanism 4 pushes the first connecting mechanism 31 closer to the second connecting mechanism 32 and applies rotational torque. At this time, the first connecting mechanism 31 rotates and moves forward, causing the multiple alloy metal wires 33 connected between the two to intertwine and spirally stack. This stacking greatly reduces the porosity between the metal wires, forming a dense, sponge-like porous filtration structure, forcing the water flow to fully contact the alloy surface, and greatly enhancing the polarization scale inhibition effect.

[0036] Reference Figure 11 The process by which the drive mechanism 4 switches the first connecting mechanism 31 to the cleaning station is as follows: the drive mechanism 4 drives the first connecting mechanism 31 to rotate in the opposite direction and move away from the second connecting mechanism 32, retracting into the mounting chamber 21 of the mounting body 2. At this time, multiple alloy metal wires 33 are straightened, untangled, and separated from each other, forming a loose, gap-like structure. Dirt cannot remain between the wires and is easily removed.

[0037] In some preferred embodiments of the drive mechanism 4, the drive mechanism 4 drives the first connecting mechanism 31 to move and the drive mechanism 4 drives the second connecting mechanism 32 to rotate, thereby enabling the first connecting mechanism 31 and the second connecting mechanism 32 to move and rotate relative to each other. For example, the drive mechanism 4 includes a shifting component and a rotating component 42. The shifting component is an electric push rod, a cylinder, or a hydraulic cylinder, and the rotating component 42 is a motor. The shifting component is connected to the first connecting mechanism 31, and the rotating component 42 is connected to the second connecting mechanism 32. In another preferred embodiment, the rotating component 42 includes a drive motor 421 and a pair of drive gears 422. The pair of drive gears 422 mesh with each other, and the drive motor 421 drives the second connecting mechanism 32 to rotate through the pair of drive gears 422.

[0038] In some embodiments, the surfaces of both the first connecting mechanism 31 and the second connecting mechanism 32 are divided into a central region 311, a middle region 312, and an edge region 313. The two ends of the multiple alloy metal wires 33 are fixed only to the middle region 312, and they are arranged in a ring.

[0039] The end of the metal wire is fixed in the middle area 312 of the connecting mechanism; after the metal wire is compressed along the axial direction, it is easier to deform along the path around the central axis, and under the guidance of the contact between the metal wires, a spiral stacked porous structure is formed, the circumferential pore distribution is more uniform, and thus the flow field consistency is improved.

[0040] A mounting hole 314 is provided in the central region 311 of the first connecting mechanism 31. A through central channel is formed along the axial direction in the space enclosed by multiple alloy metal wires 33.

[0041] This embodiment also includes a cleaning mechanism 5. The cleaning mechanism 5 can be arranged in the central region 311 of the filter element assembly through the mounting hole 314, that is, arranged in the through central channel.

[0042] In this embodiment, a mounting hole 314 is provided in the central region 311 of the first connecting mechanism 31 and / or the central region 311 of the second connecting mechanism 32; a cleaning mechanism 5 is provided at the mounting hole 314.

[0043] Preferably, mounting holes 314 are provided only in the central region 311 of the first connecting mechanism 31. Taking the example of providing mounting holes 314 in the central region 311 of the first connecting mechanism 31 and arranging cleaning structures only in the mounting holes 314 of the central region 311 of the first connecting mechanism 31, the principle and structure of arranging cleaning structures in the mounting holes 314 of the central region 311 of the second connecting mechanism 32 are the same as those for arranging cleaning structures in the mounting holes 314 of the central region 311 of the first connecting mechanism 31.

[0044] Reference Figures 4-6 The cleaning mechanism 5 includes at least a water injection pipe 51 and a water injection pump 52. The water injection pump 52 can also adopt other water supply pressurization structures. The water injection pump 52 can directly or indirectly connect the water injection pipe 51 to the purified water in the treatment chamber 11. Preferably, the water injection pump 52 connects the treatment chamber 11 to the water injection pipe 51 through a connecting pipe 54. The purified water can be the effluent water after treatment by the filter element assembly, or it can be an external cleaning water source; preferably, it is treated water, and even more preferably, it is the purified water remaining in the water purification body 1. The purified water is output from the water injection pipe 51 by the water injection pump 52, and the purified water flows onto the alloy metal wire 33 to clean the alloy metal wire 33.

[0045] The drive mechanism 4 can also directly or indirectly move the cleaning mechanism 5 between the first connecting mechanism 31 and the second connecting mechanism 32, and drive the cleaning mechanism 5 to move outside the first connecting mechanism 31 and the second connecting mechanism 32. At the filtration station, the cleaning mechanism 5 can be in a retracted position to avoid occupying the flow channels of multiple alloy metal wires or affecting the stacking of the metal wires; at the cleaning station, the cleaning mechanism 5 extends into or near the loose gap structure formed by the metal wires and contacts the metal wires to achieve brushing.

[0046] In some embodiments, the extension and retraction of the cleaning mechanism 5 can be indirectly achieved by the drive mechanism 4. For example, the first connecting mechanism 31 moves toward the second connecting mechanism 32, and the first connecting mechanism 31 moves on the water injection pipe 51 until the water injection pipe 51 leaves the mounting hole 314 of the first connecting mechanism 31. At this time, the first connecting mechanism 31 and the second connecting mechanism 32 reach the filtration station, and the water injection pipe 51 is located outside the first connecting mechanism 31 and the second connecting mechanism 32. In other embodiments, the extension and retraction of the cleaning mechanism 5 can also be indirectly achieved by the drive mechanism 4. For example, the drive mechanism 4 can drive both the first connecting mechanism 31 and the water injection pipe 51 of the cleaning mechanism 5 to move.

[0047] The water injection pipe 51 passes through the mounting hole 314 and is located within the mounting chamber 21. Multiple oblique holes 511 are formed on the water injection pipe 51. These oblique holes 511 are at least axially inclined relative to the axis of the water injection pipe 51, and their outlets intersect with the alloy metal wire 33. The water jet ejected through the oblique holes 511 impacts the surface of the metal wire and the interior of its gaps at a certain angle, thereby washing away attached contaminants and carrying them downstream. Because the metal wires have been de-stacking to form a gap structure at the cleaning station, the water jet can more easily penetrate deep into the gaps, resulting in more thorough cleaning coverage.

[0048] The outlet of the oblique hole 511 also faces the second connecting mechanism 32. Since the water injection pipe 51 is located outside the first connecting mechanism 31 and the second connecting mechanism 32 when the first connecting mechanism 31 and the second connecting mechanism 32 are in the filtration station, there is a distance between the water injection pipe 51 and the second connecting mechanism 32 when the first connecting mechanism 31 and the second connecting mechanism 32 are in the cleaning station. The setting of the oblique hole 511 further increases the rationality of the spatial layout and allows the metal wire to be thoroughly cleaned.

[0049] In some embodiments, the water injection pipe 51 is at least rotatably fitted to the mounting chamber 21, for example, the water injection pipe 51 is rotatably connected to the mounting chamber 21 via a bearing, bushing, or rotary seal assembly; the oblique hole 511 is also radially inclined relative to the axis of the water injection pipe 51, and the outlet direction of the oblique hole 511 is opposite to the axis of the water injection pipe 51, that is, the spray direction of the oblique hole 511 has both circumferential and tangential components. In this embodiment, the water injection pipe 51 is connected to the connecting pipe 54 via a rotary joint 55.

[0050] When the water injection pipe 51 drains water outward, the water flow through the inclined hole 511 exerts a reaction force on the water injection pipe 51. This reaction force includes at least a tangential component, thus giving the water injection pipe 51 a tendency to rotate. When the water pressure is high enough, the water injection pipe 51 can rotate automatically during the spraying process, allowing the spray direction to cover different angles around the circumference, further reducing cleaning dead zones and improving rinsing uniformity.

[0051] In some other embodiments, a soft cleaning body 6 is also provided on the water injection pipe 51. The soft cleaning body 6 may be a bristle bundle, an elastic scraper, or a sponge strip, etc. The soft cleaning body 6 preferably has a certain degree of elasticity, providing a stable adhesion force and accommodating the positional deviation of the metal wire when in contact with it.

[0052] During the cleaning process, the middle or upper part of the soft cleaning body 6 comes into contact with the alloy metal wire 33 to achieve scrubbing. Here, "middle or upper part" means that when the water injection pipe 51 is inserted, the soft cleaning body 6 is within the effective height range of the metal wire's action area, allowing it to directly contact the metal wire and perform physical contact cleaning.

[0053] During the filtration stage, the soft cleaning body 6 and the water injection pipe 51 are located outside the first connecting mechanism 31 and the second connecting mechanism 32 to avoid affecting the formation of a dense porous filtration structure by the spiral stacking of metal wires.

[0054] Reference Figure 15 At any point during the switching process between the cleaning station and the filtration station, i.e., when the first connecting mechanism 31 and the second connecting mechanism 32 are stopped, the alloy metal wires 33 are in a partially bent and spring-back or drooping state, and the end of the soft cleaning body 6 is located outside the multiple alloy metal wires 33, so that the soft cleaning body 6 is in contact with the multiple alloy metal wires 33. The soft cleaning body 6 can clean the metal wires.

[0055] Reference Figure 8 In some embodiments, the soft cleaning body 6 is elastic, and an expansion chamber 61 is formed inside the soft cleaning body 6; the soft cleaning body 6 is directly or indirectly connected to the water injection pipe 51. The soft cleaning body 6 is also provided with a plurality of overflow holes 62, which are connected to the expansion chamber 61.

[0056] When the water supply pipe 51 supplies water, some of the water flows into the expansion chamber 61, causing the soft cleaning body 6 to expand or change in hardness, thereby increasing the contact pressure between it and the metal wire at the cleaning station and improving the scraping effect; at the same time, water can also overflow through the overflow hole 62 to form a water film adhering to the wall, which accompanies the rinsing area and prevents dirt from accumulating at the base of the bristles.

[0057] In some embodiments, multiple soft cleaning bodies 6 are provided, and all of the multiple soft cleaning bodies 6 are inclined toward the mounting hole 314. The inclined arrangement makes it easier for the soft cleaning bodies 6 to guide and conform to the metal wire when the water injection pipe 51 is inserted, and at the same time forms a larger sweeping envelope when the water injection pipe 51 rotates or swings, thereby increasing the circumferential coverage area.

[0058] Reference Figure 10During the filtration stage, the second connecting mechanism 32 is located on the inner wall of the processing chamber 11. During the filtration stage, the first connecting mechanism 31 is close to the second connecting mechanism 32. The first connecting mechanism 31 may be located near the communication area between the processing chamber 11 and the installation chamber 21, or may partially enter the processing chamber 11.

[0059] Reference Figure 11 When switching to the cleaning station, the first connecting mechanism 31 moves into the installation chamber 21, making the space inside the processing chamber 11 more open, which facilitates the cleaning mechanism 5 to extend into the installation chamber 21 for brushing and spraying. The water injection pipe 51 of the cleaning mechanism 5 is mainly located in the installation chamber 21. The water sprayed out from the water injection pipe 51 will hit the alloy metal wire 33 for cleaning, and the water will also hit the inner wall of the installation chamber 21. After being reflected on the inner wall of the installation chamber 21, it will hit the alloy metal wire 33 again, increasing the cleaning effect.

[0060] Reference Figures 7-8 In some embodiments, a piston structure 7 is provided on the first connecting mechanism 31, and the piston structure 7 abuts against the inner wall of the mounting chamber 21 to form a seal. The piston structure 7 may be a piston ring with a sealing ring, a lip seal, or a combination seal, and its outer diameter fits with the inner wall of the mounting chamber 21 to form a dynamic seal, preferably forming an effective barrier at the filtration station to reduce bypass leakage.

[0061] Meanwhile, a sealing structure 71 is provided at the end of the water injection pipe 51. At the filtration station, the sealing structure 71 abuts against the mounting hole 314 to create a tight seal. The sealing structure 71 can be a conical seal, an O-ring end face seal, or a spherical seal, etc., used to close the mounting hole 314 channel at the filtration station, preventing water from short-circuiting through the mounting hole 314 into the mounting chamber 21 during the treatment process, thus affecting the treatment effect.

[0062] Furthermore, during the filtration stage, the piston structure 7 is located at the intersection of the mounting chamber 21 and the processing chamber 11 and is tightly sealed against the inner wall of the mounting chamber 21. This positional relationship allows the piston structure 7 to simultaneously isolate the two chambers and stabilize the axial position of the first connecting mechanism 31, thereby ensuring that the metal wire forms a stable, dense, porous filter structure at the filtration stage.

[0063] Reference Figure 17In some embodiments, the alloy wire 33 is provided with multiple protrusions 34, and the diameter of the protrusions 34 is larger than the diameter of the alloy wire 33. The protrusions 34 can be spaced apart along the length of the wire, or they can be irregularly distributed along the length. The protrusions 34 can be spherical, short columnar, spindle-shaped, annular, or other shapes that can form an outwardly convex profile. The material of the protrusions 34 is the same as that of the alloy wire 33, and they are integrally formed. When the metal wires are compressed and spirally stacked at the filtration station, the protrusions 34 can form point-to-point or point-to-line contacts, avoiding large-area adhesion between the metal wires, thereby maintaining a relatively stable pore network, which is beneficial for obtaining a more consistent flow field distribution and pressure drop characteristics.

[0064] Reference Figure 8 , Figures 10-13 , Figure 16 In some embodiments, a baffle 53 is provided inside the water injection pipe 51. The baffle 53 has a blocking portion 531 and a hollow portion 532: when the blocking portion 531 is located at the corresponding position of the inclined hole 511, the baffle 53 is used to block the inclined hole 511, inhibiting or blocking water from spraying out of the inclined hole 511; when the hollow portion 532 is located at the corresponding position of the inclined hole 511, the baffle 53 is used to open the inclined hole 511, allowing water to spray out through the inclined hole 511 to rinse the metal wire.

[0065] The baffle 53 switches the on / off state of the inclined hole 511 by moving axially within the water injection pipe 51.

[0066] Furthermore, the sealing structure 71 has an elastic portion, meaning that the sealing structure 71 can deform towards the water injection pipe 51 when subjected to external pressure. The sealing structure 71 is an elastic shell, and the baffle 53 is connected to the sealing structure 71. Therefore, when the elastic portion of the sealing structure 71 deforms due to force, it can drive the baffle 53 to move within the water injection pipe 51, thereby achieving the switching of the baffle 53's position.

[0067] The water purification main body 1 is also equipped with a fixing body 81, which is referenced to Figure 9 An external force mechanism 8 is provided on the fixed body 81, and the drive motor 421 can also be provided on the fixed body 81. A through hole is provided on the second connecting mechanism 32, through which the external force mechanism 8 can be pushed outward and push the piston structure 7, thereby causing the baffle tube 53 to move inside the water injection pipe 51; after the external force mechanism 8 is retracted, the baffle tube 53 returns to its original position inside the water injection pipe 51. The external force mechanism 8 can be an electromagnetic push rod, a cylinder, a lead screw motor, or other mechanism capable of reciprocating linear motion. In some embodiments, the two positions of the baffle 53 correspond to the following flow path states: After the baffle 53 is reset, for example, when the external force mechanism 8 is retracted, the hollow part 532 of the baffle 53 aligns with the inclined hole 511, causing the inclined hole 511 to open; at the same time, the blocking part 531 of the baffle 53 aligns with the connection port, causing the connection port to be blocked, that is, the water supply is restricted.

[0068] In this state, the cleaning water is mainly sprayed out through the inclined hole 511, and the water injection pipe 51 rotates to form a jet pointing towards the metal wire area to achieve a comprehensive flushing of the metal wire. Since the water supply at the connection port is limited, the cleaning body is not filled with water or is filled with a small amount of water to avoid premature expansion of the cleaning body during the rotation of the water injection pipe 51, which would cause undesirable squeezing and friction with the metal wire and reduce the risk of mechanical damage to the metal wire.

[0069] The external force mechanism 8 pushes and pushes the piston structure 7, causing the elastic part of the sealing structure 71 to deform under force, driving the baffle tube 53 to move to another position inside the water injection pipe 51. At this time, the blocking part 531 of the baffle tube 53 aligns with and blocks the inclined hole 511, closing the inclined hole 511. Simultaneously, the hollow part 532 of the baffle tube 53 aligns with the water supply passage of the connection port, thereby opening the connection port. Cleaning water preferentially enters the connection port and supplies the cleaning body, causing the cleaning body to expand in a preset manner for close-fitting cleaning of specific areas. The water injection pipe 51 can also be switched between water injection and water stop, and the cleaning body can be switched between expansion and contraction, allowing the cleaning body to actively rub against the alloy metal wire 33.

[0070] The work process is as follows: The driving mechanism 4 drives the first connecting mechanism 31 to move toward the second connecting mechanism 32. The first connecting mechanism 31 and the second connecting mechanism 32 are close together, and multiple alloy metal wires 33 are close to each other and spirally stacked to form a dense porous filter structure. Water injection pipe 51 is retracted to the clearance position, sealing structure 71 is tightly sealed against mounting hole 314; piston structure 7 is tightly sealed against inner wall of mounting chamber 21. The water to be treated flows through the treatment chamber 11 and passes through a dense porous filter structure before being output.

[0071] The drive mechanism 4 drives the first connecting mechanism 31 to move away from the second connecting mechanism 32, so that the filter element assembly is switched to the cleaning station; the metal wires are stretched and unstacked to form a loose line gap structure. The cleaning mechanism 5 extends between the first connecting mechanism 31 and the second connecting mechanism 32 under the direct or indirect action of the driving mechanism 4, so that the soft cleaning body 6 comes into contact with the metal wire. The water pump 52 is started, and the cleaning water is sprayed out from the inclined hole 511 through the water injection pipe 51 to rinse the metal wire; in the embodiment with radially inclined inclined hole 511, the water injection pipe 51 generates a rotational tendency under the jet reaction force, thereby improving circumferential coverage. If the soft cleaning body 6 is an expansion structure, some water flows into the expansion chamber 61 and overflows through the overflow hole 62, achieving a composite cleaning of "expansion and bonding + overflow flushing"; After cleaning is completed, the water pump 52 stops, the cleaning mechanism 5 retracts, and the drive mechanism 4 drives the second connecting mechanism 32 back to the filtration station to enter the next round of filtration operation.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
