Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a demagnetizing filter device. Background Technology

[0002] Liquid treatment is an essential part of industrial production and daily life. Untreated liquids usually contain magnetic impurities as well as common impurities. Therefore, before liquids are used in industrial or domestic applications, it is necessary to remove these impurities to improve their purity and quality.

[0003] Currently, magnetic separation and filtration devices are commonly used to remove magnetic and ordinary impurities from liquids. However, when using existing devices for impurity removal, the simple internal filtration structure and insufficient contact area with the liquid make it difficult to effectively remove different impurities, resulting in poor liquid treatment effect and efficiency. Utility Model Content

[0004] In view of the above problems, this application provides a demagnetizing filter device that can effectively remove impurities from liquids and improve the liquid treatment effect and efficiency.

[0005] This application provides a demagnetizing filter device, comprising: a processing chamber including an inlet, an outlet, and a plurality of working chambers distributed and interconnected in the flow direction between the inlet and the outlet; magnetic components correspondingly disposed in each of the working chambers; and filter screens correspondingly disposed in each of the working chambers and arranged in the flow direction.

[0006] In the technical solution of this application embodiment, magnetic components and filter screens are installed in each working chamber of the processing chamber of the demagnetizing filter device. When the liquid passes through each working chamber, the magnetic components can adsorb and remove magnetic impurities in the liquid, while the filter screens can filter and remove ordinary impurities in the liquid, thereby achieving effective removal of different impurities in the liquid. Furthermore, the liquid can sequentially pass through multiple working chambers along the flow direction, and during the flow process, the liquid can fully contact multiple magnetic components and multiple filter screens, further improving the removal effect of different impurities in the liquid. After the liquid is discharged from the outlet, no further processing of the liquid is required, improving the liquid processing effect and efficiency.

[0007] In some embodiments, the mesh size of the filter screens arranged in each of the working chambers increases sequentially along the direction from the inlet to the outlet. As the liquid flows along the direction from the inlet to the outlet, the mesh size of the filter screens in the working chambers increases sequentially, so impurities in the liquid can be filtered sequentially in order of decreasing volume, thereby achieving graded filtration of impurities in the liquid and improving the filtration effect and filtration accuracy.

[0008] In some embodiments, the processing chamber is further provided with alternating first and second guide plates. The first guide plate extends from the top to the bottom of the processing chamber and forms passage portions at intervals, while the second guide plate extends from the bottom to the top and forms passage portions at intervals. The top and bottom are arranged opposite to each other in a first direction. By placing the first guide plate at the top of the processing chamber and the second guide plate at the bottom of the processing chamber, passage portions can be formed between the first guide plate and the bottom of the processing chamber, and between the second guide plate and the top of the processing chamber. When the liquid passes through each working chamber, it needs to pass through the entire working chamber along the first direction, thereby achieving full contact with the magnetic components and filter screen in each working chamber and improving the filtration effect.

[0009] In some embodiments, adjacent working chambers are isolated by one of the first and second guide plates and connected by the passage portion, and the processing chamber forms a serpentine flow channel between its inlet and outlet. This design allows the liquid to flow sequentially through each working chamber from the inlet to the outlet of the processing chamber, ensuring sufficient flow and contact with the magnetic components and filter screens within each working chamber. This guarantees the filtration effect and makes full use of the space within the processing chamber, resulting in a smaller overall size of the demagnetizing filtration device.

[0010] In some embodiments, the inlet and the outlet are arranged at both ends of the housing sidewall of the processing chamber in the first direction, and the inlet and the outlet are diagonally distributed in the processing chamber. This design allows liquid to flow into the working chamber at one end through the inlet and out through the outlet in the working chamber at the other end. The arrangement of the inlet and outlet at both ends of the housing in the first direction ensures that the liquid can flow through the entire processing chamber in the first direction before being discharged through the outlet. This ensures contact between the liquid and the magnetic components and the filter screen, thereby guaranteeing the filtration effect.

[0011] In some embodiments, the number of the first guide plate and the second guide plate are equal. The inlet is located at the bottom of the side wall of the housing in the first direction, and the outlet is located at the top of the side wall of the housing in the first direction. Liquid can enter the working chamber through the bottom inlet and gradually fill the working chamber. As the liquid gradually increases, it can pass through each working chamber sequentially along the serpentine flow channel, eventually filling the working chamber connected to the outlet and exiting through the top outlet. This ensures the contact area between the liquid and the magnetic components and filter screen in each working chamber, improving the filtration effect.

[0012] In some embodiments, the filter screen is disposed over the magnetic component within its corresponding working chamber, with the opening of the screen facing the flow direction. After passing through the magnetic component, the liquid also passes through the filter screen disposed over the magnetic component. Because the opening of the filter screen faces the flow direction of the liquid, the filter screen can filter out impurities in the liquid and retain them on the side closer to the inlet along the flow direction of the liquid, ensuring the filtering effect of the filter screen on impurities.

[0013] In some embodiments, along the direction from the inlet to the outlet, the mesh size of each filter screen is 40% to 60% of that of the next filter screen. Setting the mesh size ratio of two adjacent filter screens within this range allows each filter screen to filter impurities of different areas according to this ratio as the liquid passes through multiple filter screens sequentially, thereby achieving graded filtration of impurities in the liquid and improving filtration efficiency and accuracy.

[0014] In some embodiments, the mesh size of each filter screen is 10-1000 mesh. Setting the mesh size of the filter screen within this range ensures that each filter pore has a suitable passage area, thereby filtering larger impurities that need to be filtered, ensuring filtration effect and accuracy, and ensuring that the liquid flowing out of the outlet meets the usage requirements.

[0015] In some embodiments, the filter screen is connected to the side wall of the working chamber, and the side wall includes at least two of the first guide plate, the second guide plate, and the shell side wall of the processing chamber. Since the liquid flows in the first direction within each working chamber, this arrangement allows the filter screen to completely cover its respective working chamber in a plane perpendicular to the first direction. This ensures that all liquid flowing in the working chamber along the flow direction comes into contact with the filter screen, thereby achieving thorough filtration and improving the filtration effect and accuracy.

[0016] In some embodiments, the filter screen includes a first filter section and a second filter section connected together. The first filter section is an inclined annular structure, and its outer edge is connected to the side wall of the working chamber. The second filter section is a cover structure extending along the first direction, with its edge connected to the inner edge of the first filter section. The second filter section is entirely covered over the end of the magnetic component. In this embodiment, the first filter section connects the second filter section and the side wall of the chamber. When some liquid passes directly through the first filter section, the first filter section can also filter this portion of liquid. The second filter section, entirely covered over the end of the magnetic component, reduces the impact force of the liquid flow, thereby slowing down the flow rate and allowing the liquid to remain at the magnetic component for a longer time. This allows the magnetic component to fully adsorb magnetic impurities in the liquid, improving the overall filtration effect and filtration accuracy.

[0017] In some embodiments, the processing chamber includes a housing and a top cover. The housing includes a bottom wall and a housing side wall surrounding the periphery of the bottom wall. The top cover and the bottom wall are respectively disposed at the top and bottom of the housing along the first direction. The top cover is detachably connected to the housing side wall. When excessive impurities accumulate inside the processing chamber, the top cover can be disassembled from the housing, and the interior of the housing can be cleaned, facilitating the overall cleaning process.

[0018] In some embodiments, the magnetic components in adjacent working chambers are respectively connected to the upper cover and the bottom wall. This design provides a fixed base for the magnetic components within the processing chamber, allowing them to be fixed to the top or bottom of the chamber. As the liquid flows in the flow direction, they are not affected by the liquid's impact force and thus ensure effective adsorption of magnetic impurities in the liquid at a fixed position.

[0019] In some embodiments, the filters in adjacent working chambers are respectively located at the top and bottom of their respective working chambers in a first direction, and each magnetic component is fixedly connected to the filter in its corresponding working chamber. This design allows the magnetic components to be fixed in the processing chamber by the filter, providing a fixed foundation. As the liquid flows in the flow direction, it will not move due to the impact of the liquid, thus ensuring the adsorption effect of magnetic impurities in the liquid at a fixed position.

[0020] In some embodiments, the magnetic assembly includes a plurality of magnetic elements spaced apart from each other, each magnetic element extending along the first direction. When the liquid passes between the plurality of spaced magnetic elements extending along the first direction, it can have sufficient contact area with the surface of the magnetic elements, thereby improving the adsorption effect of the magnetic assembly on magnetic impurities in the liquid.

[0021] In some embodiments, in the first direction, the ratio between the extension length L1 of the magnetic element and the extension length L2 of the working chamber satisfies: 0.5 ≤ L1 / L2 ≤ 0.8. Setting the ratio of the extension lengths of the magnetic element and the working chamber within this range ensures that the liquid has sufficient contact area with the magnetic element within the working chamber, thus guaranteeing the adsorption and removal effect of magnetic impurities.

[0022] In some embodiments, the magnetic properties of the magnetic component are 1000-20000 GS. Setting the magnetic properties of the magnetic component within this range ensures its adsorption capacity for magnetic impurities in the liquid, thus guaranteeing the effective adsorption and removal of these impurities.

[0023] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0040] Currently, liquids are ubiquitous in both industrial production and daily life. In industrial production, liquids are used for temperature control, hydraulic control, heat transfer media, chemical reactions, cleaning and purification, and fire prevention; in daily life, liquids serve as cleaning agents and drinking water. Therefore, liquids are an indispensable part of human production and daily life.

[0041] Before being used in industrial production and daily life, liquids must meet the requirements of different scenarios. Untreated liquids contain numerous impurities, including magnetic impurities and non-magnetic impurities, which affect the purity and quality of the liquid. In industrial production, liquids containing impurities can impact their functionality. If used in production equipment, impurities can affect the equipment's operation, leading to lower efficiency or even malfunctions. In daily life, liquids containing impurities may fail to clean parts effectively when used as cleaning fluids, and they may not meet drinking water standards and are unsuitable for direct consumption.

[0042] To remove various impurities from liquids, liquid treatment equipment is typically used. This equipment usually includes only a simple filtration structure, capable of removing only common impurities, or only a magnetic adsorption component, capable of removing only magnetic impurities. When removing different impurities from a liquid, the liquid needs to be passed through different devices sequentially to remove common and magnetic impurities separately. This type of liquid treatment equipment not only has poor impurity removal efficiency but also requires at least two devices for removing different impurities, resulting in a large overall size and a large footprint.

[0043] Furthermore, current liquid processing equipment typically employs simple structures and easy-to-install conventional and magnetic impurity removal components. Consequently, the contact area and time between the liquid and these components are insufficient, leading to ineffective removal of impurities and poor treatment results. Liquids that fail to meet usage requirements may require further impurity removal, significantly impacting processing efficiency.

[0044] Based on the above considerations, in order to solve the problem of poor liquid treatment effect and efficiency of current liquid treatment equipment, the inventors, after in-depth research, designed a demagnetizing filter device. Multiple interconnected working chambers 13 are set between the inlet 11 and outlet 12 of the treatment chamber 10 of the demagnetizing filter device. Magnetic components 20 and filter screens 30 are respectively set in each working chamber 13. The magnetic components 20 are magnetic and can adsorb and remove magnetic impurities in the liquid. The filter screens 30 are arranged in the flow direction and can filter ordinary impurities in the liquid.

[0045] When this demagnetizing filter is used to remove impurities, the liquid flows from the inlet 11 through each working chamber 13 in sequence along the flow direction and is finally discharged from the outlet 12. During this flow process, both magnetic impurities and ordinary impurities in the liquid are removed multiple times, thereby ensuring that most of the impurities in the liquid can be removed, thus ensuring the treatment effect of liquid impurities.

[0046] Furthermore, each working chamber 13 is equipped with a magnetic component 20 and a filter screen 30, so that the functions of removing magnetic impurities and ordinary impurities in the liquid are integrated into the same working chamber 13, which can realize the simultaneous removal of magnetic impurities and ordinary impurities, thereby improving the processing efficiency of various impurities in the liquid.

[0047] The demagnetizing filter disclosed in this application can be applied to different scenarios in industrial production and daily life. It can be used as a small module in a large equipment or device, or as an independently set whole device. It can be set up in different application environments to remove impurities from liquids in different application environments. Different application environments can be, but are not limited to, temperature control, hydraulic control, heat transfer medium, chemical reaction, cleaning and purification and fire prevention in industrial production, as well as cleaning and drinking in daily life.

[0048] According to some embodiments of this application, refer to Figures 1 to 4 ,in Figure 1This is a schematic diagram of the overall structure of a demagnetizing filter device provided in some embodiments of this application. This application provides a demagnetizing filter device, including a processing chamber 10, including an inlet 11, an outlet 12, and a plurality of working chambers 13 distributed and interconnected in the flow direction between the inlet 11 and the outlet 12; magnetic components 20, correspondingly disposed in each working chamber 13; and filter screens 30, correspondingly disposed in each working chamber 13 and arranged in the flow direction.

[0049] like Figure 1 As shown in the figure, the first direction X is the vertical direction in the figure, which is also the height direction after the demagnetizing filter device is installed.

[0050] The processing chamber 10 is a cavity structure with multiple interconnected working chambers 13 inside. The processing chamber 10 is connected to the outside through its inlet 11 and outlet 12. The processing chamber 10 can be of various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. The materials of the processing chamber 10 and the magnetic component 20 can be of various types, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. In this embodiment, the shape and material of the processing chamber 10 are not particularly limited.

[0051] Specifically, the inlet 11 and outlet 12 of the treatment chamber 10 are both tubular structures, which can be, but are not limited to, round pipes, square pipes, etc., and the inner diameter or side length of the tubular structure is 1-10cm. Within this range, the flow rate of liquid entering or exiting the treatment chamber 10 can be guaranteed, and the flow rate of liquid in the treatment chamber 10 can be avoided from being too large or too small, which would affect the removal effect of impurities in the liquid.

[0052] Each working chamber 13 has a magnetic component 20 and a filter screen 30 inside. The magnetic component 20 is magnetic and can adsorb magnetic or metallic impurities in the liquid, thereby retaining the impurities on its own surface and achieving the demagnetization effect of the liquid. The filter screen 30 can be made of, but is not limited to, stainless steel, nylon, plastic, non-woven fabric, and synthetic fiber.

[0053] Please refer to Figure 1 When the liquid needs to be treated in the treatment chamber 10 to remove impurities, the liquid containing impurities can enter the interior of the treatment chamber 10 through the inlet 11, that is, enter the working chamber 13 connected to the inlet 11. Then the liquid can pass through each working chamber 13 in sequence along the flow direction from the inlet 11 to the outlet 12. In each working chamber 13, magnetic impurities and ordinary impurities are removed by the magnetic component 20 and the filter screen 30 respectively. After multiple impurity removals in multiple working chambers 13, the liquid that meets the requirements is discharged from the treatment chamber 10 through the outlet 12 for further processing or direct use.

[0054] like Figure 1 As shown, Figure 1The arrows indicate the flow direction of the liquid from inlet 11 to outlet 12. In subsequent embodiments, the liquid will flow in this direction to pass through each working chamber 13 in sequence, where impurities will be adsorbed and filtered.

[0055] By installing magnetic components 20 and filter screens 30 in each working chamber 13 of the processing chamber 10 of the demagnetizing filter device, the liquid flowing through the working chamber 13 can simultaneously contact the magnetic components 20 and filter screens 30, thereby effectively removing magnetic impurities and ordinary impurities from the liquid. Furthermore, the liquid can sequentially pass through multiple working chambers 13 along the flow direction, allowing multiple sets of magnetic components 20 and filter screens 30 to remove and filter impurities from the liquid multiple times, thoroughly removing liquid impurities. This avoids the need for further demagnetization or filtration after the liquid is discharged from the outlet 12, thus improving the liquid treatment effect and efficiency.

[0056] According to some embodiments of this application, optionally, the number of filter meshes of the filter screens 30 arranged in each working chamber 13 along the direction from the inlet 11 to the outlet 12 shows an increasing trend.

[0057] In the embodiments of this application, the overall area of ​​the filter screens 30 in each working chamber 13 is equal and the shape is the same. Therefore, the more mesh number of the filter screen 30, the smaller the passing area of ​​each filter hole, and the smaller the volume of impurities that the filter screen 30 can filter. Conversely, the fewer mesh number of the filter screen 30, the larger the passing area of ​​each filter hole, and the larger the volume of impurities that the filter screen 30 can filter.

[0058] As the liquid flows along the flow direction from inlet 11 to outlet 12, it passes through multiple filter screens 30 with an increasing number of mesh sizes in sequence. This allows impurities in the liquid to be filtered in order of decreasing volume, thereby achieving graded filtration of impurities in the liquid and improving the filtration effect and filtration accuracy.

[0059] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the processing chamber 10 is also provided with alternating first guide plates 14 and second guide plates 15. The first guide plates 14 extend from the top to the bottom of the processing chamber 10 and form passage portions 16 at intervals. The second guide plates 15 extend from the bottom to the top and form passage portions 16 at intervals. The top and bottom are arranged opposite to each other in the first direction X.

[0060] The first guide plate 14 and the second guide plate 15 are alternately arranged in the processing chamber 10. That is, along the direction from the inlet 11 to the outlet 12, the first guide plate 14 is followed by the second guide plate 15 at intervals, and then another first guide plate 14 is followed by the second guide plate 15 at intervals. The subsequent guide plates are arranged in the same order, so as to realize the alternating arrangement of the first guide plate 14 and the second guide plate 15.

[0061] In this embodiment, the number of the first guide plate 14 and the second guide plate 15 in the processing chamber 10 can be one or more, that is, at least one first guide plate 14 and at least one second guide plate 15 are alternately distributed in the processing chamber 10.

[0062] By placing the first guide plate 14 at the top of the processing chamber 10 and the second guide plate 15 at the bottom of the processing chamber 10, passage portions 16 can be formed between the first guide plate 14 and the bottom of the processing chamber 10, and between the second guide plate 15 and the top of the processing chamber 10. When the liquid passes through each working chamber 13, it needs to pass through the entire working chamber 13 along the first direction X before entering the next working chamber 13 through the passage portion 16 and passing through the working chamber 13 along the first direction X. This achieves full contact with the magnetic components 20 and the filter screen 30 in each working chamber 13, thereby improving the filtration effect.

[0063] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, adjacent working chambers 13 are isolated by one of the first guide plate 14 and the second guide plate 15 and connected by the passage 16, and the processing chamber 10 forms a serpentine flow channel between its inlet 11 and outlet 12.

[0064] The processing chamber 10 forms a serpentine flow channel between its inlet 11 and outlet 12. The serpentine flow channel has multiple bends, such as... Figure 1 and Figure 2 As shown, the direction of the arrow in the figure is the extension direction of the serpentine flow channel, and there is a first guide plate 14 and a second guide plate 15 in the figure. Therefore, the serpentine flow channel shown in the figure is specifically an S-shaped flow channel, that is, the flow channel bends twice.

[0065] By setting a serpentine flow channel in the processing chamber 10, the liquid can completely pass through each working chamber 13 along the first direction X during the flow process, so that the liquid can fully contact the magnetic components 20 and the filter screen 30 in each working chamber 13, ensuring the filtration effect, and making full use of the space in the processing chamber 10, so that the size of the entire demagnetizing filter device is small.

[0066] According to some embodiments of this application, optionally, the inlet 11 and the outlet 12 are arranged at both ends of the housing sidewall 172 of the processing chamber 10 in the first direction X, and the inlet 11 and the outlet 12 are diagonally distributed in the processing chamber 10.

[0067] The inlet 11 and outlet 12 are arranged at both ends of the housing side wall 172 of the processing chamber 10 in the first direction X. That is, the inlet 11 and outlet 12 are located at the top or bottom of the housing side wall 172. The inlet 11 is in the same position as part of the passage 16 in the first direction X, and the outlet 12 is in the same position as other parts of the passage 16 in the first direction X.

[0068] The inlet 11 and outlet 12 are diagonally distributed in the processing chamber 10. The inlet 11 is connected to the working chamber 13 of the processing chamber 10 on one side, and the outlet 12 is connected to the working chamber 13 of the processing chamber 10 on the other side, so that the liquid can flow fully in the arrangement direction of the multiple working chambers 13 and pass through all the working chambers 13 in sequence.

[0069] After entering the working chamber 13 on one side through inlet 11, the liquid needs to pass through each working chamber 13 sequentially along a serpentine channel until it reaches the working chamber 13 on the other side, and finally exits through outlet 12. This allows the liquid to pass through all working chambers 13 and be adsorbed and filtered by the magnetic components 20 and filter screens 30 in all working chambers 13, so that magnetic impurities and ordinary impurities in the liquid are fully removed, ensuring the overall filtration effect.

[0070] According to some embodiments of this application, optionally, the number of first guide plates 14 and second guide plates 15 are equal, the inlet 11 is located at the bottom of the housing sidewall 172 in the first direction X, and the outlet 12 is located at the top of the housing sidewall 172 in the first direction X.

[0071] like Figure 1 and Figure 2 As shown, the number of the first guide plate 14 and the second guide plate 15 is equal, one in each case. In actual production, the number of the first guide plate 14 and the second guide plate 15 can be set to multiple. The number of working chambers 13 can be set according to the filtration effect requirements, and the number of the first guide plate 14 and the second guide plate 15 can be designed according to the number of working chambers 13, as long as the two numbers are equal.

[0072] The inlet 11 is located at the bottom of the housing sidewall 172 in the first direction X. The guide plate adjacent to the inlet 11 is the second guide plate 15. When the liquid enters the bottom of the working chamber 13 through the inlet 11, as the liquid volume increases, the liquid gradually accumulates to the top of the working chamber 13, and then flows into the next working chamber 13 through the passage 16 at the top of the second guide plate 15. The outlet 12 is located at the top of the housing sidewall 172 in the first direction X. The guide plate adjacent to the outlet 12 is the first guide plate 14. The liquid enters the bottom of the last working chamber 13 through the passage 16 at the bottom of the first guide plate 14. As the liquid volume increases, the liquid gradually accumulates to the top of the working chamber 13, and finally is discharged through the outlet 12.

[0073] The placement of the inlet 11 prevents the liquid from directly reaching the bottom of the first working chamber 13 under gravity after entering, resulting in a short contact time with the magnetic component 20 and filter screen 30. Insufficient contact would negatively impact impurity removal. Similarly, the placement of the outlet 12 ensures that the liquid accumulates from bottom to top in the last working chamber 13, extending its time within the chamber and allowing for sufficient contact with the magnetic component 20 and filter screen 30. This maximizes the contact area between the liquid and these components, improving impurity removal efficiency.

[0074] According to some embodiments of this application, optionally, the filter screen 30 is covered by the magnetic component 20 in its corresponding working chamber 13, and the opening of the cover is arranged facing the flow direction.

[0075] like Figure 1 As shown, when the filter screen 30 is installed in the working chamber 13, it is arranged in an arc shape, and the inner direction of the arc shape is the direction of the cover opening of the filter screen 30. Optionally, the filter screen 30 can also be a structure that can cover the magnetic component 20, such as a square structure or a trapezoidal structure.

[0076] As the liquid passes through the filter screen 30 along the flow direction, the filter screen 30 is positioned so that its opening faces the flow direction of the liquid. The liquid is filtered by the filter screen 30 in all directions, ensuring that there is sufficient area between the filter screen 30 and the liquid for thorough filtration. After the liquid passes through, the filter screen 30 can filter out most of the impurities in the liquid and retain them on the side near the inlet 11 along the flow direction of the liquid, thus ensuring the filtration effect of the filter screen 30 on impurities.

[0077] According to some embodiments of this application, optionally, along the direction from inlet 11 to outlet 12, the mesh count of each filter screen 30 is 40% to 60% of the mesh count of the next filter screen 30.

[0078] Since the mesh size of each filter screen 30 is 40% to 60% of that of the next filter screen 30, the filtration area of ​​each filter screen 30 is larger than that of the next filter screen 30. When filtering liquid, the volume of impurities that each filter screen 30 can filter is 40% to 60% of the volume of impurities that the previous filter screen 30 can filter, preferably 50%.

[0079] Therefore, by setting the ratio of the mesh size of adjacent filter screens 30 to 40% to 60%, the volume of impurities filtered by the filter screen 30 is about half that of the previous one. This allows for the filtration of impurities of various sizes, achieving graded filtration of impurities and preventing different impurities from accumulating in the same filter screen 30, which could cause clogging of the filter holes. This ensures the filtration effect and filtration accuracy of the device.

[0080] According to some embodiments of this application, optionally, the mesh size of each filter screen 30 is 10-1000 mesh.

[0081] In the embodiments of this application, the mesh size of the filter screen 30 is selected and determined according to the volume of impurities in the liquid under actual production and living needs. Since the filter screen 30 needs to completely cover the working chamber 13 in the first direction, it is also related to the specific size of the working chamber 13. For example, if the overall volume of the demagnetizing filter device and its working chamber 13 is too large, the mesh size can be increased accordingly so that the filter hole passage area meets the filtration requirements.

[0082] Setting the filter screen 30 to this mesh size range can filter impurities in most commonly used liquids, ensuring filtration effect and accuracy, and thus guaranteeing that the filtered liquid meets usage requirements.

[0083] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the filter screen 30 is connected to the cavity side wall of the working chamber 13, and the cavity side wall includes at least two of the first guide plate 14, the second guide plate 15, and the shell side wall 172 of the processing chamber 10.

[0084] like Figure 1 and Figure 2As shown, when the filter screen 30 is located in the working chamber 13 near the inlet 11, the edge of the filter screen 30 is connected to the housing side wall 172 and the second guide plate 15; when the filter screen 30 is located in the working chamber 13 in the middle, the edge of the filter screen 30 can be connected to the first guide plate 14, the second guide plate 15 and the housing side wall 172, or only the two sides of the filter screen 30 can be connected to the first guide plate 14 and the second guide plate 15, which can also achieve the fixation of the filter screen 30; when the filter screen 30 is located in the working chamber 13 near the outlet 12, the edge of the filter screen 30 is connected to the housing side wall 172 and the first guide plate 14.

[0085] When the liquid flows through each working chamber 13 along the flow direction, it will exert an impact force on the filter screen 30. Since the edges of the filter screen 30 have a fixed base, the filter screen 30 can not only resist the impact force of the liquid, but also completely cover the working chamber 13 in the plane perpendicular to the first direction, leaving the impurities in the liquid on one side of the filter screen 30, thus achieving full filtration of the liquid and improving the filtration effect and filtration accuracy.

[0086] According to some embodiments of this application, optionally, such as Figure 1 and Figure 4 As shown, the filter screen 30 includes a first filter section 31 and a second filter section 32 connected to each other. The first filter section 31 is an inclined annular structure, and the outer edge of the first filter section 31 is connected to the cavity sidewall of the working cavity 13. The second filter section 32 is a cover structure extending along the first direction X. The edge of the second filter section 32 is connected to the inner edge of the first filter section 31, and the second filter section 32 is entirely covered on the end of the magnetic component 20.

[0087] The first filter section 31 is inclined along the direction of liquid flow, and its annular structure is adapted to the cross-sectional shape of the working chamber 13. The outer edge of the first filter section 31 needs to fit against the inner surface of the working chamber 13 to prevent liquid from flowing through the gap between the first filter section 31 and the inner surface of the working chamber 13, thus affecting the filtration effect. For example, Figure 4 As shown, the working chamber 13 has a rectangular cross-sectional shape, and the first filter section 31 also has a square ring structure.

[0088] The edge shape of the second filter section 32 is the same as the inner edge shape of the first filter section 31, so that the two can be connected in a closed manner. When the liquid passes through the filter screen 30 in the flow direction, part of the liquid passes through the first filter section 31, and the rest of the liquid passes through the second filter section 32. The connection between the first filter section 31 and the second filter section 32 realizes the complete coverage of the working chamber 13, ensuring the filtration effect of all liquids flowing into the working chamber 13.

[0089] Furthermore, the second filter section 32 extends along the first direction X and can cover the end of the magnetic component 20. Since the second filter section 32 has a certain length, after the liquid enters into the second filter section 32, it can flow out of the second filter section 32 on each surface of the second filter section 32, so that the second filter section 32 and the liquid have sufficient contact area. This not only slows down the flow rate of the liquid, but also filters the liquid over a larger area, thereby achieving sufficient filtration of the liquid.

[0090] According to some embodiments of this application, optionally, such as Figure 1 and Figure 3 As shown, the processing chamber 10 includes a housing 17 and a top cover 18. The housing 17 includes a bottom wall 171 and a housing side wall 172 arranged around the periphery of the bottom wall 171. The top cover 18 and the bottom wall 171 are respectively disposed at the top and bottom of the housing 17 along the first direction X. The top cover 18 is detachably connected to the housing side wall 172.

[0091] The housing 17 has a bottom wall 171 and a housing side wall 172 arranged around the periphery of the bottom wall 171. The top cover 18 can cover the top of the housing 17 to form a closed space inside the processing chamber 10. This space is divided into multiple working chambers 13 by a first guide plate 14 and a second guide plate 15. The housing side wall 172 is perpendicularly connected to the bottom wall 171.

[0092] Optionally, the housing sidewall 172 can be fixedly connected to the top cover 18, while the bottom wall 171 can be detachably connected to the housing sidewall 172. When disassembling, the bottom wall 171 can be disassembled to facilitate cleaning of the entire processing chamber 10 from the bottom.

[0093] Furthermore, the top cover 18 is detachably connected to the side wall 172 of the housing via a clamp or other snap-fit ​​structure. The top surface of the top cover 18 also has a pull-out structure 19, which can be a ring-shaped structure fixed to the top cover 18. The user's hand can be inserted into the ring-shaped pull-out structure 19, making it convenient for the user to disassemble and assemble the top cover 18 and the housing 17.

[0094] After prolonged use, the magnetic component 20 and filter screen 30 in the processing chamber 10 will accumulate a lot of impurities on the surface of the magnetic component 20 and one side of the filter screen 30. When too many impurities accumulate, the user can disassemble the top cover 18 from the housing 17 and clean the inside of the housing 17, which facilitates the overall cleaning process and avoids the reduction in filtration effect caused by too many impurities inside.

[0095] According to some embodiments of this application, optionally, such as Figure 1 As shown, the magnetic components 20 in the adjacent working chambers 13 are respectively connected to the upper cover 18 and the bottom wall 171.

[0096] The magnetic components 20 in adjacent working chambers 13 are respectively connected to the upper cover 18 and the bottom wall 171. That is, when the magnetic component 20 in one working chamber 13 is connected to the upper cover 18, the magnetic component 20 in the preceding or following working chamber 13 is connected to the bottom wall 171, thereby realizing the alternating installation of the magnetic components 20 in multiple working chambers 13.

[0097] Specifically, when liquid flows into a working chamber 13 from the bottom inlet 11 or through portion 16, the magnetic component 20 in this working chamber 13 is connected to the bottom wall 171; when liquid flows into a working chamber 13 from the top through portion 16, the magnetic component 20 in this working chamber 13 is connected to the top cover 18. This arrangement allows the liquid to come into contact with the magnetic component 20 after flowing into the working chamber 13, thus achieving sufficient contact. The magnetic component 20 can fully adsorb magnetic impurities in the liquid, ensuring the adsorption effect.

[0098] The magnetic component 20 is connected to the upper cover 18 and the bottom wall 171, so that the magnetic component 20 has a fixed base and will not move due to the impact of the liquid when subjected to the impact force of the liquid, thereby ensuring the adsorption effect of magnetic impurities in the liquid in a fixed position.

[0099] Specifically, the magnetic assembly 20 can also be detachably connected to the upper cover 18 and the bottom wall 171. Each magnetic component 21 of the magnetic assembly 20 is connected by a threaded connection, which allows the magnetic assembly 20 to be disassembled during overall cleaning, making it more convenient to clean the magnetic assembly 20.

[0100] According to some embodiments of this application, optionally, the filter screens 30 in adjacent working chambers 13 are respectively disposed at the top and bottom of their respective working chambers 13 in the first direction X, and each magnetic component 20 is fixedly connected to the filter screen 30 in the corresponding working chamber 13.

[0101] The magnetic component 20 is fixedly connected to the filter screens 30 that are alternately arranged at the top and bottom. It also has a fixed base and will not move due to the impact of the liquid when subjected to liquid impact, thus ensuring the adsorption effect of magnetic impurities in the liquid in a fixed position.

[0102] The edge of the filter screen 30 is also detachably connected to the side wall of the working chamber 13. Before completely disassembling the top cover 18, the filter screen 30 must be removed first to avoid affecting the separation and disassembly of the top cover 18. In addition, the filter screen 30 can also be disassembled and cleaned, improving the convenience of overall cleaning.

[0103] Since the magnetic components 20 are all fixed on the filter screen 30, the magnetic components 20 can be disassembled at the same time when the filter screen 30 is disassembled, which facilitates the overall disassembly. The filter screen 30 and the magnetic components 20 can also be cleaned together, improving the overall cleaning efficiency.

[0104] According to some embodiments of this application, optionally, such as Figure 4 As shown, the magnetic component 20 includes a plurality of magnetic elements 21 arranged at intervals, each of which extends along a first direction X.

[0105] Each magnetic component 21 of the magnetic assembly 20 is a magnetic rod structure extending along the first direction X, and each magnetic rod structure has sufficient length to have sufficient adsorption area.

[0106] Multiple magnetic rods are arranged at intervals to form an array structure, allowing liquid to flow between the magnetic rods. This causes magnetic impurities in the liquid to be subjected to adsorption forces in different directions, ensuring the adsorption effect of the magnetic component 20 on magnetic impurities.

[0107] The plurality of magnetic elements 21 in the magnetic assembly 20 can be arranged in different ways, for example, as Figure 4 As shown, the magnetic components 21 in the magnetic assembly 20 are divided into two rows, with six magnetic components 21 in each row. The arrangement of the magnetic components 21 in the embodiments of this application includes, but is not limited to, the arrangement described above.

[0108] According to some embodiments of this application, optionally, such as Figure 2 As shown, in the first direction X, the ratio between the extension length L1 of the magnetic element 21 and the extension length L2 of the working cavity 13 satisfies: 0.5≤L1 / L2≤0.8.

[0109] Each magnetic component 21 extends along the first direction X, and its length direction is the same as the first direction X. Since the liquid flows along the first direction X in each working chamber 13, the length direction of the working chamber 13 is also the first direction X.

[0110] When the ratio of the extension length L1 of the magnetic component 21 to the extension length L2 of the working cavity 13 meets this range, the magnetic component 21 has a sufficient extension length in the first direction X, thereby ensuring that it has a sufficient adsorption area and ensuring the adsorption effect.

[0111] According to some embodiments of this application, optionally, the magnetic element 21 has a magnetic field strength of 1000-20000GS.

[0112] GS (Gauss) is a unit of magnetic flux density used to describe the strength of a magnetic field. When the magnetic flux density of magnetic component 21 is 1000 GS, its magnetic field is relatively weak; when the magnetic flux density of magnetic component 21 is 20000 GS, its magnetic field is relatively strong.

[0113] By setting the magnetism of the magnetic component 21 within this range, the magnetic component 21 is guaranteed to have sufficient adsorption force for magnetic impurities in the liquid, thus ensuring the adsorption and removal effect of the magnetic component 21 on magnetic impurities.
