Description

Technical Field

[0001] This application relates to the field of water treatment technology, and more specifically, to a super magnetic separator. Background Technology

[0002] In wastewater treatment, magnetic seeds are often added to coagulants to form magnetic flocs, which are then separated from the water using an ultra-magnetic separator. Some known ultra-magnetic separators typically include a containment chamber and an adsorption assembly within the chamber. The adsorption assembly contains an adjustable magnetic component. When the magnetic component generates a magnetic field, the magnetic flocs are adsorbed onto the surface of the adsorption component and scraped off by a scraper. However, known ultra-magnetic separators suffer from the technical problem of poor separation efficiency of magnetic flocs. Summary of the Invention

[0003] This application provides an ultra-magnetic separator to solve the technical problem of poor separation effect of magnetic flocs.

[0004] The embodiments of this application are implemented as follows: This application provides a supermagnetic separator, comprising: a body defining a receiving cavity, one end of which has an opening in the vertical direction, and the other end of which has a liquid outlet, the opening for inputting a mixed liquid containing magnetic flocs; a plurality of adsorption components extending in the vertical direction, each adsorption component being movably disposed relative to the receiving cavity in the vertical direction, the adsorption components being configured to extend into the mixed liquid from the opening and exit the liquid surface of the mixed liquid; each adsorption component comprising an annular body, a magnetic component, and a temporary storage component, the annular body having a liquid inlet channel extending in the vertical direction. The magnetic component is located inside the annular body and its magnetism is adjustable. The magnetic component generates a magnetic field to adsorb magnetic flocs in the mixture onto the outer surface of the annular body and the inner wall of the inlet channel. The magnetic component also deactivates the magnetic field to detach the adsorbed magnetic flocs. The temporary storage component is located at the lower end of the annular body and collects the detached magnetic flocs. The temporary storage component has an openable and closable slag discharge door. The discharge component is located on the outside of the machine body and at the end of the machine body near the opening. The discharge component docks with the temporary storage component to discharge the magnetic flocs inside the temporary storage component.

[0005] According to the magnetic separator of this application, when processing a mixed liquid, the adsorption component extends downwards into the liquid within the receiving chamber from the opening; when slag discharge is required, the adsorption component is raised upwards, leaving the liquid surface from the opening. When the magnetic component generates a magnetic field, magnetic flocs in the mixed liquid are adsorbed onto the outer surface of the annular body and the inner wall of the inlet channel; when the magnetic component closes the magnetic field, the adsorbed magnetic flocs detach from the annular body and fall downwards under gravity. A temporary storage component is connected to the lower end of the annular body to receive the detached magnetic flocs. During adsorption, the slag discharge door remains closed, allowing the magnetic flocs to gradually accumulate within the temporary storage component. After adsorption is complete, the adsorption component is raised vertically until the temporary storage component is completely out of the liquid surface, at which point the slag discharge door connects with the discharge component, and the temporarily stored magnetic flocs fall directly into the discharge component under gravity, achieving the collection and discharge of the magnetic flocs. Thus, the entire adsorption component can extend vertically into or out of the mixed liquid surface from the opening, eliminating the need for an additional inlet on the side wall of the receiving chamber, thereby simplifying the structure of the receiving chamber. During sludge discharge, the adsorption components can be vertically offset from the liquid surface, preventing detached magnetic flocs from falling back into the treated water and reducing the likelihood of re-mixing with the liquid, resulting in low moisture content in the discharged sludge. The open design serves as both the inlet and outlet for the adsorption components, reducing the number of openings and sealing points in the equipment and improving reliability. The adsorption components move only vertically, with a simple trajectory, minimizing the risk of spatial interference between the adsorption components and the inlet or outlet pipes.

[0006] In one possible implementation: The super magnetic separator also includes multiple annular scrapers, which are sleeved on the outside of the corresponding adsorption components. Each annular scraper is movably arranged relative to the adsorption component along the vertical direction. The annular scrapers are used to scrape the magnetic flocs on the outer surface of the adsorption component so that they fall into the temporary storage component.

[0007] In one possible implementation: The inner surface of the annular scraper is provided with an elastic scraper blade, which extends obliquely from the annular scraper blade toward the adsorption assembly and abuts against the outer surface of the adsorption assembly; and / or, the temporary storage assembly includes a temporary storage wall and a plurality of connecting walls, one end of the temporary storage wall is located on the outer side of the adsorption assembly near the liquid outlet and is correspondingly arranged with the annular scraper blade; the other end of the temporary storage wall is provided with the slag discharge gate, and the plurality of connecting walls are spaced apart along the circumference of the adsorption assembly to connect the temporary storage wall and the adsorption assembly.

[0008] In one possible implementation: The temporary storage component includes a hydrophobic coating on the inner surface of the temporary storage enclosure, the hydrophobic coating being used to reduce the adhesion of the magnetic flocs to the inner surface of the temporary storage enclosure; and / or, an annular water-blocking baffle is provided on the inner side of the temporary storage enclosure, the annular water-blocking baffle extending downwardly from the inner surface of the temporary storage enclosure toward the center, the free end of the annular water-blocking baffle forming a gap for the magnetic flocs to pass through.

[0009] In one possible implementation: The super magnetic separator also includes a flushing device, which is fixed above the opening of the receiving cavity. When the slag discharge door is connected to the discharge component, the flushing device is used to inject flushing water into the liquid inlet channel of the annular body. The flushing water washes down along the inner wall of the liquid inlet channel and discharges the residual magnetic flocs through the temporary storage component and the discharge component.

[0010] In one possible implementation: The bottom of the receiving cavity is provided with a water collecting baffle, which is located above the liquid outlet. The water collecting baffle has a water passage hole corresponding to the lower end of the adsorption component. The water collecting baffle is also provided with a sealing cover, which is used to seal the water passage hole. When the adsorption component is connected to the discharge component, the sealing cover closes the water passage hole.

[0011] In one possible implementation: The super magnetic separator also includes a lifting component, which is located outside the machine body. The lifting component is connected to multiple adsorption components and is used to drive the multiple adsorption components to move between a first position and a second position. When the adsorption component is in the first position, the adsorption component is immersed in the liquid in the receiving cavity. When the adsorption component is in the second position, the temporary storage component rises above the liquid surface, and the slag discharge door is connected to the discharge component.

[0012] In one possible implementation: When the adsorption component is in the first position, the slag discharge door of the temporary storage component is in the closed state; when the adsorption component is in the second position, the slag discharge door of the temporary storage component is in the open state; a linkage component is provided between the slag discharge door and the machine body, and the linkage component is used to open the slag discharge door when the adsorption component moves to the second position.

[0013] In one possible implementation: The magnetic component includes multiple annular electromagnetic coils stacked vertically, and the energization of each annular electromagnetic coil is independently controllable. Before the adsorption component moves from the first position to the second position, the annular electromagnetic coil at the top layer is de-energized first, while the remaining annular electromagnetic coils remain energized, so that the magnetic flocs on the inner wall of the liquid inlet channel fall off layer by layer from top to bottom and slide into the temporary storage component.

[0014] In one possible implementation: The number of lifting components is multiple, and each lifting component is connected to an adsorption component via a transmission connection. The receiving cavity is provided with multiple flow guide baffles arranged circumferentially within it, extending vertically. These baffles divide the receiving cavity into multiple independent sub-cavities, each sub-cavity corresponding to a liquid outlet. The supermagnetic separator also includes a controller configured to control each lifting component to operate in a preset sequence, such that at least one adsorption component is in the first position and another adsorption component is in the second position at the same time.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] See Figure 1This embodiment provides a super magnetic separator 100, including: a body 10 defining a receiving cavity 11, with an opening 12 at one end of the receiving cavity 11 along the vertical direction Z and a liquid outlet 13 at the other end of the receiving cavity 11 along the vertical direction Z, the opening 12 being used to input a mixture containing magnetic flocs; multiple adsorption components 20 extending along the vertical direction Z, each of the multiple adsorption components 20 being movably arranged relative to the receiving cavity 11 along the vertical direction Z, the multiple adsorption components 20 being configured to extend into the mixture from the opening 12 and leave the liquid surface of the mixture; each adsorption component 20 includes an annular body 21, a magnetic component 23, and a temporary storage component 24, the annular body 21 being opened along the vertical direction Z A through-flow liquid inlet channel 22 is provided. A magnetic component 23 is located inside the annular body 21 and its magnetism is adjustable. The magnetic component 23 is used to generate a magnetic field to adsorb magnetic flocs in the mixture onto the outer surface of the annular body 21 and the inner wall of the liquid inlet channel 22. The magnetic component 23 is also used to turn off the magnetic field so that the adsorbed magnetic flocs detach. A temporary storage component 24 is located at the lower end of the annular body 21 and is used to collect the detached magnetic flocs. The temporary storage component 24 is provided with an openable and closable slag discharge door 25. A discharge component 30 is located on the outside of the machine body 10 and at the end of the machine body 10 near the opening 12. The discharge component 30 is used to dock with the temporary storage component 24 to discharge the magnetic flocs in the temporary storage component 24.

[0024] According to the super magnetic separator 100 of this embodiment, when processing the mixed liquid, the adsorption component 20 extends downward from the opening 12 into the liquid in the receiving cavity 11; when slag discharge is required, the adsorption component 20 is lifted upward and leaves the liquid surface from the opening 12. When the magnetic component 23 generates a magnetic field, the magnetic flocs in the mixed liquid are adsorbed onto the outer surface of the annular body 21 and the inner wall of the liquid inlet channel 22; when the magnetic component 23 closes the magnetic field, the adsorbed magnetic flocs detach from the annular body 21 and fall downward under the action of gravity. The temporary storage component 24 is connected to the lower end of the annular body 21 to receive the detached magnetic flocs. During the adsorption process, the slag discharge door 25 remains closed, allowing the magnetic flocs to gradually accumulate in the temporary storage component 24. After the adsorption is completed, the adsorption component 20 is lifted vertically upward in the Z direction until the temporary storage component 24 is completely away from the liquid surface, and then the slag discharge door 25 connects with the discharge component 30, and the temporarily stored magnetic flocs fall directly into the discharge component 30 under the action of gravity, realizing the collection and discharge of the magnetic flocs.

[0025] Thus, in this embodiment, the adsorption component 20 can extend into or out of the mixed liquid surface from the opening 12 in the vertical direction Z, eliminating the need for an additional inlet on the side wall of the receiving cavity 11, thereby simplifying the structure of the receiving cavity 11. During sludge discharge, the position of the adsorption component 20 can be completely offset from the liquid surface in the vertical direction Z, preventing the detached magnetic flocs from falling back into the treated water, reducing the possibility of the magnetic flocs remixing with the liquid, and resulting in low moisture content in the discharged sludge. The opening 12 serves as both the inlet and outlet channel for the adsorption component 20, reducing the number of openings and sealing points in the equipment and improving reliability. The adsorption component 20 moves only in the vertical direction Z, with a relatively simple movement trajectory, reducing the risk of spatial interference between the adsorption component 20 and the inlet or outlet pipes.

[0026] In some embodiments, the super magnetic separator 100 further includes multiple annular scrapers 40, which are sleeved on the outer side of the corresponding adsorption components 20. Each annular scraper 40 is movably disposed relative to the adsorption component 20 in the vertical direction Z. The annular scraper 40 is used to scrape magnetic flocs from the outer surface of the adsorption component 20, causing them to fall into the temporary storage component 24. When the adsorption component 20 moves in the vertical direction Z, the outer surface of the annular body 21 slides relative to the inner edge of the annular scraper 40, causing the annular scraper 40 to scrape off the magnetic flocs attached to the outer surface. The scraped flocs fall into the temporary storage component 24 below under the action of gravity. In this way, the scraping action of the annular scraper 40 is directly driven by the lifting and lowering motion of the adsorption component 20 itself, eliminating the need for a separate drive device or transmission mechanism for the annular scraper 40, reducing the number of moving parts in the equipment and lowering the complexity of the transmission process.

[0027] In other embodiments, the annular scraper 40 may also move relative to the adsorption component 20 in the vertical direction Z under the action of the driving component.

[0028] In some embodiments, the inner surface of the annular scraper 40 is provided with an elastic scraper 41, which extends obliquely from the annular scraper 40 toward the adsorption assembly 20 and abuts against the outer surface of the adsorption assembly 20. Thus, the obliquely positioned elastic scraper 41, while scraping off the sludge, provides the sludge with an oblique sliding surface toward the downward-facing temporary storage assembly 24. After the flocs detach from the outer surface, they slide along the oblique surface of the elastic scraper 41 into the temporary storage assembly 24, preventing them from accumulating at the scraper and from drifting to other areas of the receiving cavity 11 due to airflow or liquid surface fluctuations during the upward movement.

[0029] In some embodiments, the temporary storage component 24 includes a temporary storage wall 241 and a plurality of connecting walls 242. One end of the temporary storage wall 241 is located on the outer side of the adsorption component 20 near the outlet 13 and is correspondingly arranged with the annular scraper 40. The other end of the temporary storage wall 241 is provided with a sludge discharge door 25. The plurality of connecting walls 242 are spaced apart along the circumference of the adsorption component 20, connecting the temporary storage wall 241 and the adsorption component 20. An opening for magnetic flocs to enter is formed between two adjacent connecting walls 242. Magnetic flocs scraped off from the outer surface of the annular body 21 enter the temporary storage wall 241 through these openings, while flocs detached from the inner wall of the inlet channel 22 fall directly from the lower end of the annular body 21 into the central area of ​​the temporary storage wall 241. In this way, sludge from both sources is collected at the bottom of the temporary storage wall 241 and discharged together through the discharge component 30 when the sludge discharge door 25 is opened. The sludge collection path is uniform, with no dead corners.

[0030] In some embodiments, the temporary storage component 24 includes a hydrophobic coating on the inner surface of the temporary storage enclosure 241. The hydrophobic coating reduces the adhesion of magnetic flocs to the inner surface of the temporary storage enclosure 241. The hydrophobic coating may be made of a low surface energy material such as polytetrafluoroethylene, making it difficult for water-containing magnetic flocs to adhere to the inner surface of the enclosure. In this way, the magnetic flocs can slide along the enclosure towards the slag discharge gate 25 under relatively small gravity, reducing the risk of magnetic flocs clogging inside the temporary storage enclosure 241 and ensuring that the magnetic flocs can be discharged smoothly during slag discharge.

[0031] In some embodiments, an annular water-blocking baffle is provided on the inner side of the temporary storage wall 241. The annular water-blocking baffle extends downward at an angle from the inner surface of the temporary storage wall 241 toward the center, and the free end of the annular water-blocking baffle forms a gap for the magnetic flocs to pass through. When the detached magnetic flocs fall from above, they slide down the upper surface of the annular water-blocking baffle through the gap and enter the bottom of the temporary storage assembly 24. When the liquid in the receiving cavity 11 attempts to flow upward from the bottom of the temporary storage assembly 24 due to water flow disturbance, the lower surface of the annular water-blocking baffle faces the direction of the incoming flow. The liquid flow is blocked by the lower surface of the baffle, generating a local vortex at the gap, making it difficult to smoothly pass through the gap and flow upward. In this way, the magnetic flocs are not easily dispersed or diluted by the water flow during temporary storage, which is beneficial for maintaining the concentration of magnetic flocs and for the subsequent discharge of high-concentration magnetic flocs.

[0032] In some embodiments, the super magnetic separator 100 further includes a flushing device 50, which is fixed above the opening 12 of the receiving cavity 11. When the slag discharge door 25 is connected to the discharge component 30, the flushing device 50 injects flushing water into the liquid inlet channel 22 of the annular body 21. The flushing water flows downward along the inner wall of the liquid inlet channel 22 and discharges the residual magnetic flocs through the temporary storage component 24 and the discharge component 30. When the adsorption component 20 is raised to the slag discharge position and the slag discharge door 25 is connected to the discharge component 30 and opened, the flushing device 50 injects flushing water into the liquid inlet channel 22 of the annular body 21. The flushing water flows downward along the inner wall of the liquid inlet channel 22, flushing down any remaining small amount of magnetic flocs, which are then discharged together with the flushing water through the temporary storage component 24 and the discharge component 30. During flushing, the adsorption component 20 is completely removed from the liquid surface, and the flushing water path is completely isolated from the treated water in the receiving cavity 11. Thus, the flushing water will not enter the receiving cavity 11 to dilute the treated water and will not affect the quality of the effluent. Regular rinsing can keep the inner wall of the liquid inlet channel 22 clean and prevent residual magnetic flocs and scale from affecting adsorption efficiency after long-term operation.

[0033] In some embodiments, a water collecting baffle 60 is provided at the bottom of the receiving cavity 11, located above the liquid outlet 13. The water collecting baffle 60 has a water passage hole 61 corresponding to the lower end of the adsorption component 20. The water collecting baffle 60 also has a sealing cover 62 for sealing the water passage hole 61. When the adsorption component 20 is in the first position, the sealing cover 62 opens the water passage hole 61; when the adsorption component 20 is connected to the discharge component 30, the sealing cover 62 closes the water passage hole 61. Thus, during the slag discharge process of the adsorption component 20, even if there is still untreated liquid in the receiving cavity 11, it cannot directly enter the liquid outlet 13 through the water passage hole 61. The water discharged from the liquid outlet 13 is always water that has passed through the liquid inlet channel 22 and been adsorbed and treated by the magnetic component 23; the quality of the discharged water is not affected by the slag discharge action or the position switching of the adsorption component 20.

[0034] In some embodiments, the super magnetic separator 100 further includes a lifting assembly 70, which is located outside the machine body 10. The lifting assembly 70 is drively connected to multiple adsorption assemblies 20 and is used to drive the multiple adsorption assemblies 20 to move between a first position and a second position. When the adsorption assembly 20 is in the first position, the adsorption assembly 20 is immersed in the liquid in the receiving cavity 11. When the adsorption assembly 20 is in the second position, the temporary storage assembly 24 is lifted off the liquid surface, and the slag discharge door 25 is connected to the discharge assembly 30. In this way, the lifting assembly 70 does not occupy the effective processing volume within the receiving cavity 11, and the internal structure of the receiving cavity 11 is more compact. The external location of the lifting assembly 70 also facilitates daily maintenance and repair. The lifting assembly 70 can be an electric or hydraulic lifting assembly 70.

[0035] In some embodiments, when the adsorption component 20 is in the first position, the slag discharge door 25 of the temporary storage component 24 is in the closed state, and when the adsorption component 20 is in the second position, the slag discharge door 25 of the temporary storage component 24 is in the open state; a linkage component is provided between the slag discharge door 25 and the body 10, and the linkage component is used to open the slag discharge door 25 when the adsorption component 20 moves to the second position.

[0036] In this way, the opening timing of the slag discharge door 25 and the spatial position of the adsorption component 20 form a definite mechanical correspondence, without relying on sensors or electronic control systems. Even in the event of a power outage or control system failure, the slag discharge door 25 can only be pushed open after the temporary storage component 24 has completely risen above the liquid surface, avoiding accidental opening underwater and resulting liquid leakage.

[0037] Optionally, the slag discharge door 25 is connected to the temporary storage wall 241 via an elastic element. The linkage assembly abuts against the slag discharge door 25. When the adsorption assembly 20 moves to the second position, the force exerted by the linkage assembly on the slag discharge door 25 is greater than the elastic force of the elastic element, thereby opening the slag discharge door 25.

[0038] In some embodiments, the magnetic component 23 includes multiple annular electromagnetic coils stacked vertically in a Z-shape, and the energization of each annular electromagnetic coil is independently controllable. Before the adsorption component 20 moves from the first position to the second position, the uppermost annular electromagnetic coil is de-energized first, while the remaining annular electromagnetic coils remain energized, causing the magnetic flocs on the inner wall of the liquid inlet channel 22 to detach layer by layer from top to bottom and slide into the temporary storage component 24. In this way, each layer of magnetic flocs falls into the temporary storage component 24 in sequence. When the upper layer of magnetic flocs falls, the lower layer of magnetic flocs has not yet detached or has already fallen into the bottom of the temporary storage component 24, preventing them from entangled in each other in the middle of the liquid inlet channel 22 and forming large clumps that block the channel, thus making the detachment process of the magnetic flocs orderly and smooth.

[0039] In some embodiments, there are multiple lifting components 70, each of which is connected to an adsorption component 20 via a transmission connection. The receiving cavity 11 is provided with multiple flow guide baffles arranged circumferentially within it, extending vertically in the Z direction. These baffles divide the receiving cavity 11 into multiple independent sub-cavities 111, each sub-cavity 111 corresponding to a liquid outlet 13. The super magnetic separator 100 also includes a controller configured to control each lifting component 70 to operate in a preset sequence, such that at least one adsorption component 20 is in a first position and another adsorption component 20 is in a second position at the same time. Thus, when one group of adsorption components 20 is lifting to discharge slag, other groups of adsorption components 20 remain immersed in the liquid, ensuring uninterrupted liquid inflow and outflow from the receiving cavity 11 and maintaining continuous flow rate without requiring shutdown or pipeline switching due to slag discharge. Each sub-cavity 111 has independent inflow and outflow, preventing small amounts of scattered magnetic flocs in the slag discharge sub-cavity from entering the liquid outlets 13 of other sub-cavities, resulting in stable effluent quality.

[0040] In some embodiments, a suction device is provided on the outside of the discharge assembly 30 to extract magnetic flocs from the temporary storage assembly 24. When the slag discharge door 25 is connected to and opened by the discharge assembly 30, the suction device generates negative pressure within the discharge assembly 30. For magnetic flocs with poor flowability and high viscosity, the negative pressure can overcome the frictional resistance of the magnetic flocs at the slag discharge port, assisting the magnetic flocs in the temporary storage assembly 24 to be discharged more quickly, making the slag discharge more thorough and less prone to residue blockage.

[0041] In some embodiments, the super magnetic separator 100 further includes a water distributor. The water distributor is located at the opening 12 of the body 10. The water distributor is used to evenly distribute the mixture circumferentially into the receiving cavity 11, preventing the incoming liquid from concentrating and scouring the outer surface of the annular body 21 in a certain area. In this way, the magnetic flocs already adsorbed on the outer surface are less likely to be washed off by the incoming water flow, and the adsorption process is more stable.

[0042] In some embodiments, an outwardly extending guide eave may be provided at the upper end of the annular body 21. The projected area of ​​the guide eave is larger than the projected area of ​​the temporary storage component 24. When the liquid flowing downward along the outer surface of the annular body 21 reaches the guide eave, it is guided outward by the guide eave and drips into the peripheral area of ​​the temporary storage component 24, instead of directly entering the temporary storage component 24. In this way, the amount of liquid flowing into the temporary storage component 24 from the outer surface of the annular body 21 can be reduced, the water content of the magnetic flocs can be reduced, and the concentration of magnetic flocs discharged during slag discharge can be increased.

[0043] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.

6. The super magnetic separator according to claim 1, characterized in that: The bottom of the receiving cavity is provided with a water collecting baffle, which is located above the liquid outlet. The water collecting baffle has a water passage hole corresponding to the lower end of the adsorption component. The water collecting baffle is also provided with a sealing cover, which is used to seal the water passage hole. When the adsorption component is connected to the discharge component, the sealing cover closes the water passage hole.

7. The super magnetic separator according to claim 1, characterized in that: The super magnetic separator also includes a lifting component, which is located outside the machine body. The lifting component is connected to multiple adsorption components and is used to drive the multiple adsorption components to move between a first position and a second position. When the adsorption component is in the first position, the adsorption component is immersed in the liquid in the receiving cavity. When the adsorption component is in the second position, the temporary storage component rises above the liquid surface, and the slag discharge door is connected to the discharge component.

8. The super magnetic separator according to claim 7, characterized in that: When the adsorption component is in the first position, the slag discharge door of the temporary storage component is in the closed state; when the adsorption component is in the second position, the slag discharge door of the temporary storage component is in the open state. A linkage component is provided between the slag discharge door and the machine body. The linkage component is used to open the slag discharge door when the adsorption component moves to the second position.

9. The super magnetic separator according to claim 7, characterized in that: The magnetic component includes multiple annular electromagnetic coils stacked vertically, and the energization of each annular electromagnetic coil is independently controllable. Before the adsorption component moves from the first position to the second position, the annular electromagnetic coil at the top layer is de-energized first, while the remaining annular electromagnetic coils remain energized, so that the magnetic flocs on the inner wall of the liquid inlet channel fall off layer by layer from top to bottom and slide into the temporary storage component.

10. The super magnetic separator according to claim 7, characterized in that: The number of lifting components is multiple, and the multiple lifting components are connected to one adsorption component in a corresponding transmission. The receiving cavity is provided with multiple flow guide baffles arranged circumferentially therein. The flow guide baffles extend along the vertical direction and the multiple flow guide baffles divide the receiving cavity into multiple independent sub-cavities. Each sub-cavity is provided with a liquid outlet. The super magnetic separator also includes a controller configured to control each of the lifting components to operate in a preset sequence, so that at least one of the adsorption components is in the first position and the other adsorption component is in the second position at the same time.
