Description

Technical Field

[0001] This invention relates to the field of waste liquid treatment technology, specifically to a waste liquid treatment device for the production of high-temperature resistant, long-life electrode foil for AI servers. Background Technology

[0002] High-temperature resistant, long-life electrode foils are typically made with high-purity aluminum as the base material, combined with modified oxide films (such as Al2O3 or Al-Ti composite films) and optimized corrosion / formation processes. These foils can operate stably at temperatures above 105℃ for extended periods and significantly improve specific capacity and lifespan. Waste liquids from electrode foil production can be categorized by process: degreasing / cleaning solution, corrosion / pore-forming solution, formation (phosphoric acid or sulfuric acid) waste liquid, cleaning / neutralization water, and sediment / sludge. Each type of waste liquid has different compositions, acidity / alkalinity, and treatment difficulty. Treatment methods must be based on source separation and priority should be given to recovering reusable acids or aluminum salts.

[0003] CN120535075A discloses a waste liquid recovery device for electrode foil, used to recover and treat waste liquid generated during the electrode foil production process. The device includes a recovery tank for filtering and recovering the waste liquid. A delivery cylinder is fixedly connected to the right side of the recovery tank, an inlet pipe is fixedly connected to the upper surface of the delivery cylinder, and a drain pipe is fixedly connected to the lower surface of the recovery tank. When the scraper rotates, it contacts the inner wall of the delivery cylinder and generates friction to scrape off the metal slag adhering to the inner wall of the delivery cylinder, preventing the metal slag from clogging the tank during transport and causing difficulties in waste liquid recovery. The elastic reset action of the torsion spring drives the torsion shaft and the scraper to quickly reset, increasing the friction between the scraper and the inner wall of the delivery cylinder and promoting the scraping effect of the metal slag. The scraper vibrates during its rapid reset, causing the scraped metal slag adhering to its surface to fall off.

[0004] Degreasing, corrosion, pore formation, and cleaning water are collected separately and treated separately after removing grease and suspended solids to improve recovery efficiency. For corrosion liquids containing hydrochloric acid / sulfuric acid, hydrochloric acid can be recovered or aluminum chloride can be produced by evaporation concentration (MVR) or acid recovery process, which can significantly reduce emissions and costs. For high acid waste liquids that cannot be recovered, aluminum ions can be removed by lime neutralization and precipitation. Aluminum-containing sludge generated needs to be stably disposed of or utilized as a resource.

[0005] Lime neutralization generates a large amount of solid waste, and aluminum-containing sludge is both a burden and a potential resource. The conventional approach is "filtration reduction + solidification and landfill," while a more advanced approach is "acid dissolution to recover aluminum salts + co-processing." However, lime neutralization and precipitation result in a random distribution of aluminum ions in the lime, leading to a cumbersome treatment process and significant energy consumption. Summary of the Invention

[0006] One of the objectives of this invention is to provide a waste liquid treatment device for the production of high-temperature resistant and long-life electrode foil for AI servers. By setting up filter media to capture aluminum ions during the waste liquid treatment process, the cost of aluminum ion recycling is reduced and the aluminum ion recycling efficiency is improved.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a waste liquid treatment device for the production of high-temperature resistant and long-life electrode foil for AI servers, used for waste liquid treatment of electrode foil in the hole-forming process, which can centrally and stably recover aluminum ions during waste liquid treatment.

[0008] The waste liquid treatment device includes:

[0009] The container can be placed on the ground or in the waste liquid treatment work area. The container is sealed to prevent leakage during waste liquid treatment. The container has one inlet and one outlet. Waste liquid enters the container through the inlet and the treated waste liquid flows out through the outlet.

[0010] The rotating drum is rotatably installed inside the tank. When the waste liquid enters the tank through the inlet, it flows into the rotating drum. At least one set of filter elements is installed inside the rotating drum. The surface or interior of the filter elements is provided with a functional layer. The functional layer is constructed of a material with an affinity for aluminum ions. As the waste liquid flows through the functional layer, aluminum ions are captured by the functional layer.

[0011] An electrostatic generator is installed on both sides of the filter element or coupled to the electric field of the filter element. Through the action of the electrostatic field, aluminum ions or charged particles in the waste liquid migrate back and forth near the filter element, so that the aluminum ions can be captured by the filter element.

[0012] In a further embodiment, several cover plates are arranged circumferentially on the outer side of the rotating drum. The cover plates are hinged to the outer side or the inner side of the rotating drum. The cover plates can be opened and closed. That is, when the cover plate is open, the waste liquid can enter the interior of the rotating drum. When the cover plate is closed, the rotating drum is sealed.

[0013] Magnetic plates are fixedly installed on the inner side of the cover plate, and a control magnetic ring is installed inside the box. The control magnetic ring surrounds the rotating drum. When the rotating drum rotates and the magnetic plate moves to the position of the corresponding control magnetic ring, the magnetic force keeps the cover plate in a closed and sealed state to prevent the leakage of waste liquid inside the rotating drum. When the magnetic plate and the control magnetic ring are misaligned or the magnetic force is canceled out, the impact force of the waste liquid is applied to the cover plate, causing the cover plate to open and the waste liquid to enter the interior of the rotating drum.

[0014] In a further embodiment, a partition is provided inside the rotating drum to divide the internal chamber of the rotating drum into at least one flow chamber and at least two processing chambers. The flow chamber and the processing chamber are spaced apart, and several cover plates are opened corresponding to the flow chamber. That is, the flow chamber is used for the flow of waste liquid, and the waste liquid enters the flow chamber through the cover plate.

[0015] The filter element is installed inside the corresponding processing chamber, and multiple channels are opened on the partition plate. The flow chamber and the processing chamber are connected through the channels, and a sealing structure is set at each channel on the inner side of the partition plate. The sealing structure controls the opening and sealing of the channel.

[0016] In a further embodiment, the sealing structure at the channel includes a sealing plate, a groove opened in the inner wall of the rotating cylinder, an elastic seal and an external driving component. The sealing plate extends and contracts axially within the partition, and its size is larger than the channel opening, making the sealing process more stable.

[0017] In one embodiment, the driving element includes a spring and an electromagnet. The spring is disposed inside the partition and supported by a sealing plate. Under the support of the spring, the sealing plate is inserted into a slot and in close contact with the slot. The electromagnet is fixed inside the partition and controls the extension and retraction of the partition. The electromagnet's magnetic attraction to the partition controls the opening of the sealing plate after resisting the spring force.

[0018] In another embodiment, the drive unit includes a spring and an electromagnet. The spring is disposed inside the partition and supports the sealing plate. Under the support of the spring, the sealing plate is inserted into the slot and in close contact with the slot. The electromagnet is fixed inside the housing and located outside the rotating drum. The opening of the sealing plate is controlled by the repulsive force generated by the electromagnet.

[0019] In a further embodiment, a plurality of filter elements are disposed inside the filter element, and the functional layer is located on the surface of the filter elements.

[0020] A magnetic matrix is ​​installed on the inner wall of the baffle or the rotating drum, that is, a magnetic matrix is ​​installed on both sides of the filter element. A central component is installed inside each filter element. The central component is made of magnetic material. The magnetic matrix changes the position of the central component inside the filter element by changing the magnetic field strength or polarity, thereby adjusting the relative position or working state of the filter element to adapt to different working conditions.

[0021] Adjacent filter elements are elastically connected by connectors. The connectors are inserted into and connected to the adjacent filter elements. The connectors have elastic or extensible properties to allow the filter elements to undergo limited displacement within the filter elements and to pull or stretch the connectors during displacement to achieve linkage.

[0022] Multiple filter elements can be independent units, and the central component of each filter element has a distinguishable polarity. Under the combined action of waste liquid flow and magnetic matrix, the positioning and arrangement of each filter element within the filter element are determined.

[0023] The treatment chamber is symmetrically equipped with two filter bodies, which are divided into a first filter body and a second filter body. The first filter body and the second filter body are connected by a connecting hole in the middle to connect the two. Each filter body is equipped with a guide plate, so that the waste liquid first enters through the first filter body, is guided by the guide plate, and is discharged through the second filter body.

[0024] The guide plate can be a fixed blade, an arc-shaped guide vane, or a porous distribution plate. The material can be a corrosion-resistant metal or an engineering plastic. The angle and spacing of the guide plate are optimized according to the flow rate and particle characteristics to obtain a uniform flow velocity distribution.

[0025] The size and number of connection holes determine the flow resistance and distribution ratio of the two-stage filtration system. Multiple small holes or annular channels can be installed to avoid localized overload. Sealing and anti-clogging structures should be provided at the connection holes.

[0026] A rotatable guide disc is installed in the flow chamber. The guide disc is rotatably mounted on the inner wall of the drum. Rollers are fixed between the guide discs. The rollers are eccentrically mounted relative to the guide discs so that the rollers are kept at the lowest position under the action of gravity.

[0027] The roller body has a hollow structure and its hollow cavity corresponds to the partition channel, so that waste liquid can enter the channel from the hollow cavity of the roller body or enter the hollow cavity of the roller body from the channel.

[0028] The guide disc changes the relative position of the rollers by rotating, and works in conjunction with the rotation of the drum to achieve periodic exposure and distribution of the liquid inlet. The guide disc can be driven by a motor or rotated synchronously by the drum.

[0029] A protective plate is fixed on the outside of the roller body, and the protective plate and the roller body cooperate to form a liquid inlet; there are diversion holes at both ends of the roller body, and a through diversion groove in the middle of the roller body. The diversion groove and the diversion hole are connected. After the waste liquid enters the roller body through the protective plate, it is guided into the filter element for treatment through the diversion groove and the diversion hole.

[0030] Through the above technical solution, the present invention has the following beneficial effects:

[0031] 1. This application uses an electrostatic field to control the aluminum ions in the waste liquid to move differently from the waste liquid, so that they are captured by the filter material on the surface of the filter element. When recovering aluminum ions, only the surface filter material needs to be treated, without the need for lime neutralization and precipitation to recover aluminum ions, thus further improving the efficiency of aluminum ion recovery and treatment.

[0032] 2. A magnetic matrix is ​​arranged on both sides of the inner wall of the rotating drum or partition. The magnetic matrix can drive the magnetic central component inside the filter body to move in a predetermined direction by changing the magnetic field strength or polarity, thereby changing the position or working state of the filter body inside the filter element.

[0033] 3. The filter element consists of several independent or elastically connected filter bodies. The filter bodies are linked together by elastic or stretchable connectors, allowing limited expansion and contraction during displacement to achieve linked displacement or buffering.

[0034] 4. The processing chamber adopts a first filter body and a second filter body structure connected in series. The two are connected by a central connecting hole and a guide plate is set inside to optimize the flow field distribution.

[0035] 5. A rotatable guide plate is installed in the flow chamber, and an eccentric hollow roller is fixed between the guide plates. The roller is kept at the lowest position under the action of gravity. The hollow cavity of the roller corresponds to the partition channel. With the help of the guard plate, the flow channel and the flow hole, the liquid is evenly distributed and diverted.

[0036] 6. Through the synergy of magnetic displacement, elastic linkage and diversion structure, online adaptive filtration, anti-clogging self-recovery, controllable backflushing cleaning and modular maintenance are achieved.

[0037] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

[0058] The following describes several embodiments of the present invention with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. And features of different embodiments may be interchanged if feasible.

Furthermore, the definitions of the foregoing terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.

[0060] The following explains the relationships and terms used in this application:

[0061] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism. It allows for situations where the parallelism is not absolute due to factors such as assembly tolerance, design tolerance, and structural flatness. It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0062] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0063] Ground: The ground as defined in this application is not limited to a specific material or region, but simply refers to a platform on which this application is supported, and allows for stacking, tilting, and variations in flatness. For example, cement floors, tile floors, work platforms, etc., can all be interpreted as ground.

[0064] The above explanation does not fully encompass the relationship definition given in this application, but only represents a part of it.

[0065] See Figure 1-13 As shown, the present invention provides a waste liquid treatment device for the production of high temperature resistant and long life electrode foil for AI servers, which is used to treat waste liquid in the hole-forming process of electrode foil. During the waste liquid treatment, aluminum ions can be centrally and stably recovered.

[0066] The waste liquid treatment device includes:

[0067] Box 1, which can be placed on the ground or in the waste liquid treatment work area. Box 1 is sealed. When treating waste liquid, sealing box 1 can prevent leakage of waste liquid. Box 1 is provided with an inlet and an outlet. Waste liquid enters the interior of box 1 through the inlet and the treated waste liquid flows out through the outlet.

[0068] Rotary drum 2 is rotatably installed inside the housing 1. When the waste liquid enters the housing 1 through the inlet, it flows into the interior of the rotary drum 2. At least one set of filter elements 3 is installed inside the rotary drum 2. The surface or interior of the filter element 3 is provided with a functional layer 42. The functional layer 42 is constructed of a material with affinity for aluminum ions. During the process of the waste liquid flowing through the functional layer 42, aluminum ions are captured by the functional layer 42.

[0069] The electrostatic generator 4 is set on both sides of the filter element 3 or coupled to the electric field of the filter element 3. Through the action of the electrostatic field, aluminum ions or charged particles in the waste liquid migrate back and forth near the filter element 3, so that aluminum ions can be captured by the filter element 3.

[0070] In the process of waste liquid treatment, the electrostatic field can significantly change the distribution of aluminum ions because charged ions will migrate in a directional manner in the electric field, thereby controlling the change in the position of aluminum ions.

[0071] In a further embodiment, a plurality of cover plates 11 are arranged circumferentially on the outer side of the rotating drum 2. The cover plates 11 are hinged to the outer side of the rotating drum 2 or hinged to the inner side of the rotating drum 2. The cover plates 11 can be opened and closed. That is, when the cover plates 11 are open, waste liquid can enter the interior of the rotating drum 2. When the cover plates 11 are closed, the rotating drum 2 is sealed.

[0072] Magnetic plates 12 are fixedly installed on the inner side of the cover plate 11. A control magnetic ring 13 is installed inside the housing 1. The control magnetic ring 13 is arranged around the rotating drum 2. When the rotating drum 2 rotates and the magnetic plate 12 moves to the position of the corresponding control magnetic ring 13, the magnetic force keeps the cover plate 11 in a closed and sealed state to prevent leakage of waste liquid inside the rotating drum 2. When the magnetic plate 12 and the control magnetic ring 13 are misaligned or the magnetic force is canceled, the impact force of the waste liquid is applied to the cover plate 11, causing the cover plate 11 to open and the waste liquid to enter the interior of the rotating drum 2.

[0073] By controlling the corresponding setting of the magnetic ring 13 and the magnetic plate 12, the stable control of the cover plate 11 during the waste liquid recycling process can be ensured. After the cover plate 11 is placed inside the rotating drum 2, the rotating drum 2 will open at the top position due to its own gravity.

[0074] In a further embodiment, a partition 14 is provided inside the rotating drum 2 to divide the internal chamber of the rotating drum 2 into at least one flow chamber 15 and at least two processing chambers 16. The flow chamber 15 and the processing chambers 16 are spaced apart. Several cover plates 11 are opened corresponding to the flow chamber 15, that is, the flow chamber 15 is used for the flow of waste liquid, and the waste liquid enters the interior of the flow chamber 15 through the cover plates 11.

[0075] The filter element 3 is installed inside the corresponding processing chamber 16, and multiple channels 21 are opened on the partition 14. The interior of the flow chamber 15 is connected to the interior of the processing chamber 16 through the channels 21. A sealing structure 22 is provided on the inner side of the partition 14 at each channel 21. The sealing structure 22 controls the opening and sealing of the channel 21.

[0076] It can perform controlled opening and sealing, and can seal the flow chamber 15 and the processing chamber 16 in a fixed position.

[0077] The control of the sealing structure 22 can be activated after the sealing structure 22 moves to the lowest position, thereby allowing the waste liquid to enter the processing chamber 16 from the lowest position.

[0078] In a further embodiment, the sealing structure 22 at the channel 21 includes a sealing plate 31, a slot 32 opened in the inner wall of the rotating cylinder 2, an elastic seal 33, and an external driving component 34. The sealing plate 31 extends and contracts axially within the partition 14, and its size is larger than the opening of the channel 21, making it more stable during the sealing process.

[0079] In the sealed state, the sealing plate 31 is inserted into the slot 32 and fits against the inner wall of the slot 32. The elastic sealing element 33 is fixed to the inner wall of the partition 14 and fits against the sealing plate 31. It relies on its own elastic sealing element 33 to tightly contact the sealing plate 31, ensuring the sealing stability of the sealing plate 31. The driving element 34 is set on the outside of the sealing plate 31 to control the extension and retraction of the sealing plate 31.

[0080] In one embodiment, the drive element 34 includes a spring and an electromagnet. The spring is disposed inside the partition 14 and supports the sealing plate 31. Under the support of the spring, the sealing plate 31 is inserted into the slot 32 and in close contact with the slot 32. The electromagnet is fixed inside the partition 14 and controls the extension and retraction of the partition 14. The electromagnet's magnetic attraction to the partition 14 controls the opening of the sealing plate 31 after resisting the spring force.

[0081] In another embodiment, the drive element 34 includes a spring and an electromagnet. The spring is disposed inside the partition 14 and supports the sealing plate 31. Under the support of the spring, the sealing plate 31 is inserted into the slot 32 and in close contact with the slot 32. The electromagnet is fixed inside the housing 1 and located outside the rotating drum 2. The opening of the sealing plate 31 is controlled by the repulsive force generated by the electromagnet.

[0082] Furthermore, the sealing plate 31 is made of magnetic material, and changes in the magnetic force of the electromagnet can alter the state of the sealing plate 31.

[0083] In a further embodiment, the filter element 3 is provided with a plurality of filter bodies 41 inside, and the functional layer 42 is located on the surface of the filter body 41.

[0084] A magnetic matrix 43 is provided on the inner wall of the partition 14 or the rotating cylinder 2, that is, a magnetic matrix 43 is provided on both sides of the filter element 3. A central component 44 is provided inside each filter body 41. The central component 44 is made of magnetic material. The magnetic matrix 43 changes the position of the central component 44 inside the filter body 41 by changing the magnetic field strength or polarity, thereby adjusting the relative position or working state of the filter element 3 to adapt to different working conditions.

[0085] The magnetic matrix 43 can be composed of several independent coil units or permanent magnet arrays. The coil units are arranged circumferentially / axially along the partition 14 or the rotating cylinder 2. The coil shell is made of corrosion-resistant material and is provided with cooling channels 21 for heat dissipation. Each filter body 41 corresponds to one or more sets of coils. The coils are independently driven by the control unit to achieve precise control of local field strength and polarity. The central component 44 is a columnar or ring-shaped magnetic body with a corrosion-resistant surface treatment such as nickel plating or polymer coating.

[0086] By changing the direction and amplitude of the coil current, the magnetic field gradient generates axial or radial force in the filter body 41, driving the central component 44 to move along a predetermined trajectory, thereby changing the pore arrangement, packing density or relative position of the filter body 41, so as to adjust the resistance, flux and retention selectivity.

[0087] Adjacent filter elements 41 are elastically connected by connectors 45. Connectors 45 are inserted into and connected to adjacent filter elements 41. Connectors 45 have elastic or stretchable characteristics to allow limited displacement of filter elements 41 within filter elements 3 and to pull or stretch connectors 45 during displacement to achieve linkage.

[0088] The connector 45 can be a spring pin, an elastic chain link, a rubber sleeve, or a telescopic elastic rod. One end of the connector 45 is embedded in the connection hole 52 of the filter body 41 and fixed by a snap or thread, while the other end is connected to the adjacent filter body 41.

[0089] The elastic connection allows the filter element 41 to undergo micro-displacement when it is partially blocked or magnetically displaced, changing the local gap to release the blockage; at the same time, it realizes the linkage between the filter elements 41, avoiding excessive displacement of individual elements that could lead to structural instability.

[0090] Multiple filter elements 41 can be independent units, and the central component 44 in each filter element 41 has a distinguishable polarity. Under the combined action of waste liquid flow and magnetic matrix 43, the positioning and arrangement of each filter element 41 in the filter element 3 are defined.

[0091] Each filter element 41 can be configured as a detachable module. The modular interface positioning pin, sealing ring, and quick-release buckle facilitate on-site replacement and maintenance. The modular design also supports the combination of different functional layers 42 for adsorption, catalysis, and microfiltration as needed.

[0092] The central component 44 can be designed as a permanent magnet with distinguishable polarity or a polarizable soft magnetic core. It can achieve orderly arrangement, such as alternating polarities, to form a stable spacing through coupling with the flow field via the magnetic matrix 43, thereby controlling the spacing and pore distribution of the filter body 41.

[0093] Two filter bodies 41 are symmetrically arranged inside the processing chamber 16, and are divided into a first filter body 41 and a second filter body 41. The first filter body 41 and the second filter body 41 are provided with a connecting hole 52 in the middle to connect the two. Each filter body 41 is provided with a guide plate 51 inside, so that the waste liquid first enters through the first filter body 41, is guided by the guide plate 51, and is discharged through the second filter body 41.

[0094] The first filter element 41 performs coarse interception and initial dispersion, the guide plate 51 evenly distributes the flow field and eliminates short-circuit flow, and the second filter element 41 performs fine filtration or functional treatment such as adsorption or chemical reaction. The series structure improves the overall removal rate and extends the life of the individual elements.

[0095] The guide plate 51 can be a fixed blade, an arc-shaped guide vane, or a porous distribution plate. The material is a corrosion-resistant metal or engineering plastic. The angle and spacing of the guide plate 51 are optimized according to the flow rate and particle characteristics to obtain a uniform flow velocity distribution.

[0096] The size and number of connection holes 52 determine the flow resistance and distribution ratio of the two-stage filtration. Multiple small holes or annular channels 21 can be provided to avoid local overload. A sealing and anti-clogging structure should be provided at the connection holes 52.

[0097] A rotatable guide disc 61 is provided in the flow chamber 15. The guide disc 61 is rotatably mounted on the inner wall of the rotating drum 2. A roller body 62 is fixedly arranged between the guide discs 61. The roller body is eccentrically mounted relative to the guide discs 61 so that the roller body 62 is kept at the lowest position under the action of gravity.

[0098] The roller body 62 has a hollow structure and its hollow cavity corresponds to the channel 21 of the partition plate 14, so that the waste liquid enters the channel 21 from the hollow cavity of the roller body 62 or enters the hollow cavity of the roller body 62 from the channel 21.

[0099] The guide disc 61 changes the relative position of the roller 62 by rotating, and in conjunction with the rotation of the rotating drum 2, it realizes the periodic exposure and distribution of the liquid inlet. The guide disc 61 can be driven by a motor or rotated synchronously by the rotating drum 2.

[0100] The eccentric installation allows the roller 62 to automatically return to its original position under gravity, ensuring a stable liquid inlet position and dynamic flow diversion during rotation. The hollow cavity of the roller 62 corresponds to the channel 21 of the partition 14, facilitating the temporary storage and uniform distribution of liquid within the roller 62.

[0101] A through-flow channel 65 is provided in the middle of the hollow cavity, and flow diversion holes 64 are provided at both ends of the roller body 62. After the waste liquid enters the hollow cavity through the guard plate 63, it is guided into the filter element 3 through the flow diversion channel 65 and the flow diversion holes 64. The size and number of holes of the flow diversion structure are designed according to the processing capacity to achieve uniform distribution.

[0102] A protective plate 63 is fixed on the outside of the roller body 62, and the protective plate 63 and the roller body 62 cooperate to form a liquid inlet; the roller body 62 is provided with diversion holes 64 at both ends, and a through diversion groove 65 is provided in the middle of the roller body 62. The diversion groove 65 is connected to the diversion hole 64. After the waste liquid enters the roller body 62 through the protective plate 63, it is guided into the filter element 3 for treatment through the diversion groove 65 and the diversion hole 64.

[0103] The guard plate 63 forms a stable liquid inlet and guides the liquid into the hollow cavity of the roller body 62 during rotation. It also acts as a baffle and splash preventer. The material of the guard plate 63 should be corrosion resistant and have a low friction surface to reduce deposition.

[0104] The geometry of the flow distribution groove 65 and the flow distribution hole 64, including groove depth, hole diameter, and hole spacing, determines the flow distribution uniformity. A multi-hole distribution and a gradually changing groove depth design are adopted to achieve uniform distribution from the center to the edge.

[0105] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0106] This application uses an electrostatic field to control the movement of aluminum ions in the waste liquid, thereby capturing them on the filter material on the surface of the filter element 3. When recovering aluminum ions, only the surface filter material needs to be treated, eliminating the need for lime neutralization and precipitation, thus further improving the efficiency of aluminum ion recovery.

[0107] Magnetic matrix 43 is arranged on both sides of the inner wall of the rotating drum 2 or the partition 14. The magnetic matrix 43 can drive the magnetic center component 44 inside the filter body 41 to move in a predetermined direction by changing the magnetic field strength or polarity, thereby changing the position or working state of the filter body 41 in the filter element 3.

[0108] The filter element 3 is composed of several independent or elastically connected filter bodies 41. The filter bodies 41 are linked together by elastic or stretchable connectors 45, which allow limited expansion and contraction during displacement to achieve linked displacement or buffering.

[0109] The processing chamber 16 adopts a first filter body 41 and a second filter body 41 connected in series. The two are connected by a central connecting hole 52 and a guide plate 51 is set inside to optimize the flow field distribution.

[0110] A rotatable guide disc 61 is provided in the flow chamber 15. An eccentric hollow roller 62 is fixed between the guide discs 61. The roller 62 is kept at the lowest position under the action of gravity. The hollow cavity of the roller 62 corresponds to the channel 21 of the partition plate 14. With the help of the guard plate 63, the diversion groove 65 and the diversion hole 64, the liquid is evenly distributed and diverted.

[0111] Through the synergy of magnetic displacement, elastic linkage and diversion structure, online adaptive filtration, anti-clogging self-recovery, controllable backflushing cleaning and modular maintenance are achieved.

[0112] Although the present invention has been disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the appended claims.
