Description

TECHNICAL FIELD

[0001] The utility model relates to fluid treatment technical field, concretely relates to a multistage coupling type water treatment device based on dynamic magnetic field. BACKGROUND

[0002] Magnetic energy water treatment technology changes ion crystallization behavior and colloidal particle stability in water through magnetic field physical action, and has formed large-scale application in industrial circulating water scale inhibition, agricultural irrigation and other fields. Current mainstream technical solutions can be divided into two categories: external clamping type static magnetic field device, such as patent CN213112643U, permanent magnet array is arranged symmetrically on the outer wall of the pipeline, and magnetization effect is generated by water flow vertical cutting static magnetic induction line;Built-in magnetic pole type device, such as patent CN218561184U, sets up multiple groups of fixed magnetic poles in the inner cavity of the equipment, and realizes magnetic treatment by using tangential contact between water flow and magnetic pole surface.

[0003] Although the above-mentioned solutions can realize basic magnetization function, they all adopt static magnetic field and fixed magnetic circuit topology structure, and there are key defects:

[0004] High device manufacturing cost: the magnetic energy utilization rate of static magnetic field is relatively low, the number of magnetic poles needs to be increased to reach the critical processing time, which leads to the increase of the amount of magnets and the rise of manufacturing cost.

[0005] Magnetic adsorption blocking risk: ferromagnetic suspended particles in water are easy to form chain-like agglomerates on the surface of static magnetic poles, causing channel blockage and affecting the magnetic treatment effect.

[0006] High maintenance cost: the easy-to-block problem brings equipment operation and maintenance problems, leading to customer downtime loss or cleaning cost expenditure, which is not conducive to product popularization and promotion. UTILITY MODEL CONTENTS

[0007] In view of the defects and deficiencies in the prior art, the utility model provides a multistage coupling type water treatment device based on dynamic magnetic field, which reduces the amount of magnets through dynamic magnetic field multiplexing technology, reduces the manufacturing cost, realizes intrinsic anti-blocking through rotating magnetic field design, reduces the device operation and maintenance cost, realizes continuous operation without disassembly and washing, and enhances the disturbance to ions in water through N-S alternating arrangement of magnetic poles, improves the scale inhibition effect and efficiency.

[0008] The utility model realizes the purpose through the following technical schemes:

[0009] A multi-stage coupled water treatment device based on a dynamic magnetic field includes a magnetic treatment component and a drive mechanism component for magnetically coupling and driving the magnetic treatment component. The drive mechanism component includes a motor, a magnetic drive disk, a magnetic driven disk, and a central shaft. The motor is connected to the magnetic drive disk, and the magnetic drive disk and the magnetic driven disk are driven by magnetic coupling. The magnetic driven disk is concentrically and rigidly connected to the central shaft. The magnetic treatment component includes multiple magnet fixing disks. Multiple magnets are arranged in a circumferential array on the magnet fixing disks, and the magnetic pole faces of adjacent magnets are arranged alternately in an N-S pole configuration. The magnet fixing disks are fitted onto the central shaft and rotate synchronously with the central shaft.

[0010] Furthermore, it also includes a magnetic treatment cavity assembly, which comprises a magnetic treatment cavity and side baffles and baffle rings disposed on the inner wall of the cavity. The side baffles and baffle rings divide the interior of the magnetic treatment cavity into an inlet buffer area, a stagnant area, and an outlet water collection area.

[0011] Furthermore, the magnetic treatment component is located at the center of the magnetic treatment cavity, and the water inlet buffer area and the water outlet collection area are connected to the water inlet and the water outlet, respectively; multiple magnetic treatment components are arranged sequentially along the central axis, and adjacent magnetic treatment components are isolated by limiting blocks to form a magnetic treatment channel. The magnetic treatment channel is the area through which water flows through the magnetic treatment, and the magnetic field of the area is the coupling field generated by the N-S magnetic poles in the magnetic treatment components above and below it.

[0012] Furthermore, the magnet fixing plate is made of non-magnetic material, the magnet is a neodymium iron boron permanent magnet, and the minimum distance between adjacent magnets is 1.2 to 2 times the axial height of the limiting block.

[0013] Furthermore, the side baffles consist of four pieces arranged in an equidistant circular array inside the magnetic processing cavity assembly. The water-blocking rings are two circular flat plates, respectively mounted on the upper and lower ends of the side baffles. The inner diameter of the water-blocking rings is 2-3 mm larger than the outer diameter of the magnetic processing assembly.

[0014] Furthermore, the magnets on the magnet fixing disk are arranged in a multi-layered concentric circular array. Adjacent magnets in the same ring layer have the same specifications and the N-S poles of the magnetic pole face are arranged alternately. The number of magnets in different ring layers can be set independently.

[0015] Furthermore, it also includes a magnetic guide plate, which is made of ferromagnetic material and is coaxially nested with the magnet fixing disk. It attracts the magnetic pole surfaces of each N-S alternately placed magnet, so that each magnet forms a closed magnetic field path through the magnetic guide plate.

[0016] Furthermore, it also includes an upper cover assembly, which includes a sealing cover for sealing the top of the device. The sealing cover is provided with an assembly flange connected to the magnetic processing cavity assembly, a motor fixing flange for connecting and fixing to the motor, an upper bearing fixing groove for fixing the upper bearing, and a drive disk compartment for storing the drive disk.

[0017] Furthermore, it also includes a lower cover assembly, which includes an assembly flange that is fixed to the magnetic processing chamber assembly, a support base for supporting the entire device, and a drain port for sewage discharge or maintenance.

[0018] Furthermore, a drain valve is provided at the drain outlet, and the drain valve is an electrically controlled valve.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. Magnetic field reuse and cost reduction: When the magnetic treatment component rotates, the magnetic lines of force cut the same water flow multiple times, realizing the reuse of the magnetic field, reducing the amount of magnets used by more than 50%, and reducing manufacturing costs by 30-40%.

[0021] 2. Intrinsic anti-clogging design: The rotating magnetic field causes the adsorbed ferromagnetic suspended particles to be flushed by the reverse water flow when rotating to the counter-current area, avoiding accumulation and clogging, and achieving continuous operation without disassembly and cleaning.

[0022] 3. High-efficiency magnetic treatment: Adjacent magnetic treatment components are coupled through N-S magnetic poles, and can generate a dynamic alternating magnetic field after rotation, which can significantly improve the anti-scaling efficiency.

[0023] 4. Uniform water flow distribution: The side baffle plate and the baffle ring work together to form specific water flow zones within the device, ensuring that the water flows evenly through the magnetic treatment channel and improving instantaneous treatment efficiency.

[0024] 5. Flexible adjustment: The adjustable speed motor can adjust the rotation speed of the magnetic treatment component according to different water quality and treatment requirements, and control the duration and intensity of the magnetic field's effect on the water flow to achieve the best water treatment effect.

[0025] 6. Automatic sewage discharge: The sewage discharge valve can automatically discharge the impurities and sediments accumulated in the device based on the device's operating time or water quality monitoring results, ensuring the normal operation of the device and the water treatment effect.

[0026] In summary, dynamic magnetic field reuse technology reduces the amount of magnets used, thereby lowering manufacturing costs; rotating magnetic field design achieves inherent anti-clogging; it reduces equipment maintenance costs and enables continuous operation without disassembly and cleaning; and alternating magnetic field design enhances the disturbance of ions in water, thereby improving scale prevention efficiency.

[0070] First Embodiment

[0071] As shown in Figure 1-1-1-4, this embodiment illustrates a multi-stage coupled water treatment device based on a dynamic magnetic field, comprising a drive mechanism assembly 1, an upper cover assembly 2, a magnetic treatment cavity assembly 3, a lower cover assembly 4, and a magnetic treatment assembly 5. Specifically:

[0072] As shown in Figure 2-1-2-2, the drive mechanism assembly 1 includes a motor 1-1, a magnetic drive disk 1-2, a magnetic driven disk 1-3, an upper bearing 1-4, a lower bearing 1-5, and a central shaft 1-6. The motor 1-1 is connected to the magnetic drive disk 1-2, and the magnetic drive disk 1-2 is driven by the magnetic driven disk 1-3 through magnetic coupling. The magnetic driven disk 1-3 is concentrically and rigidly connected to the central shaft 1-6. The upper bearing 1-4 and the lower bearing 1-5 are concentrically fixed at the upper and lower ends of the central shaft 1-6, respectively, to ensure the stable rotation of the central shaft 1-6.

[0073] As shown in Figures 1-1-1-4 and 3-1-3-5, the upper cover assembly 2 is the sealing cover at the top of the device. It is connected to the magnetic processing cavity assembly 3 through the assembly flange 2-3. It includes a motor fixing flange 2-1, an exhaust port 2-2, an assembly flange 2-3, an upper bearing fixing groove 2-4, and a magnetic drive disk 2-5. It is made of non-magnetic material to prevent magnetic field leakage.

[0074] As shown in Figure 4-1-4-5, the magnetic treatment cavity assembly 3 includes an inlet 3-1, an outlet 3-2, an upper mounting flange 3-3, a lower mounting flange 3-4, a water baffle ring 3-5, a side water baffle plate 3-6, and a lower bearing fixing groove 3-7.

[0075] The inlet 3-1 and outlet 3-2 are the water inlet and outlet interfaces, respectively. The side baffle 3-6 consists of four rectangular plates arranged in an equidistant circular array inside the cavity. The water baffle ring 3-5 is assembled on the upper and lower ends of the side baffle 3-6, with an inner diameter 2-3 mm larger than the outer diameter of the magnetic treatment component, guiding the water flow through the magnetic treatment channel.

[0076] As shown in Figures 1-1-1-4 and 5-1-5-5, the lower cover assembly 4 is the bottom sealing element of the device. It is connected to the magnetic treatment cavity assembly 3 through the assembly flange 4-1. It includes the assembly flange 4-1, the support base 4-2 and the drain port 4-3. The drain port 4-3 is used to discharge impurities in the device.

[0077] As shown in Figure 6-1-6-6, the magnetic processing component 5 includes a magnet fixing plate 5-1, a magnet 5-2, a large sealing ring 5-3, a small sealing ring 5-4, a magnetic guide plate 5-5, a waterproof cover plate 5-6, assembly bolt holes 5-7, a central shaft hole 5-8, and a limiting block 5-9.

[0078] The magnet fixing plate 5-1 is precision machined from non-magnetic materials (including but not limited to 316L stainless steel / ceramic reinforced nylon). The plate surface is evenly distributed with magnet mounting and positioning holes to achieve circumferential array positioning of magnets 5-2. The machining accuracy is: hole diameter tolerance ≤ ±0.05mm, ensuring the consistency of magnet spacing.

[0079] Magnet 5-2 typically uses high-performance neodymium iron boron permanent magnets, with no restrictions on geometry (including but not limited to cylindrical, sector, and polygonal shapes). Adjacent magnets have the same specifications, and the magnetic pole faces are arranged alternately with N-S poles. The angle between adjacent magnetic pole faces is 180° (they cannot be opposite each other). They are arranged in a circular array with the central axis of the magnet fixing disk (5-1) as the reference.

[0080] The minimum spacing between adjacent magnets 5-2 should be 1.2 to 2 times the axial height of limit block 5-9.

[0081] The large sealing ring 5-3 and the small sealing ring 5-4 are made of rubber or other sealing materials. Their function is to work with the waterproof cover plate 5-6 through the bolts installed in the mounting bolt holes 5-7 to achieve waterproof and moisture-proof protection and fixation of the magnet 5-2 in the magnetic treatment assembly.

[0082] The magnetic guide plate 5-5 is a ring-shaped plate structure made of ferromagnetic material, coaxially nested with the magnet fixing plate 5-1 and magnetically adsorbed. All magnets 5-2 form a closed magnetic circuit, integrating the discrete magnetic field into an axially penetrating magnetic field, reducing magnetic flux leakage and improving magnetic field utilization.

[0083] The limiting block 5-9 is a cylinder made of the same material as the magnet fixing plate 5-1, with a central shaft through hole in the center, which is responsible for controlling the height of the magnetic processing channel 5-10. The axial length of the limiting block 5-9 is used to set the distance between the surfaces of the two sets of magnet fixing plates 5-1.

[0084] The axial length of the limiting blocks 5-9 is 5-30mm (the length of the limiting blocks is determined according to the hardness of the inlet water and the parameters of the magnet).

[0085] The magnetic treatment channel 5-10 is the middle area after the two sets of magnet fixing disks 5-1 are assembled in an axial array, and it is the necessary channel for water to pass through during magnetic treatment.

[0086] Effective processing volume: V = π(R - r)H (R is the outer radius of the magnetic plate, r is the radius of the limiting block, and H is the axial length of the limiting block)

[0087] Assembly method:

[0088] As shown in Figure 7-1-7-3, multiple magnetic processing components 5 are arranged concentrically and are limited and isolated by limiting blocks 5-9, thus forming multiple magnetic processing channels 5-10. Between two adjacent magnetic processing channels 5-10, two magnetic processing components 5 are set back to back, that is, the waterproof covers 5-6 of the two magnetic processing components 5 are placed concentrically and fastened with bolts to form an integral structure.

[0089] As shown in Figure 7-1, two magnetic treatment components 5 are required to form each magnetic treatment channel. Therefore, the number of magnetic treatment channels n = C / 2 (where C is the total number of magnetic treatment components). The number of magnetic treatment channels 5-10 should be determined based on the total water processing capacity of the device to meet actual operational needs.

[0090] As shown in Figure 7-2, within the magnetic treatment channel 5-10, the magnetic pole faces of the magnets 5-2 in the magnetic treatment component 5 are arranged alternately in N-S configurations, with adjacent magnetic pole faces forming an angle of 180°, thus creating a spatially alternating magnetic field 5-11. When water flows through, charged ions are deflected by periodic Lorentz forces under the influence of the alternating magnetic field, improving ion migration efficiency.

[0091] As shown in Figure 8-1, four side baffles (3-6) are fixed to the inner wall of the magnetic treatment cavity (3) in an equidistant circular array. Combined with the structural design of the baffle ring (3-5), this creates four independent water flow zones within the magnetic treatment cavity: an inlet buffer zone A, a stagnant flow zone B, an outlet water collection zone C, and a stagnant flow zone D. The purpose of zone A (inlet buffer zone) is to effectively buffer the water entering the cavity and distribute it as evenly as possible to each magnetic treatment channel (5-10), preventing air resistance or turbulence from affecting the magnetic treatment efficiency of the device. Zones B and D (stagnant flow zones) are designed to ensure that the water flows from zone A to zone C fully through the magnetic treatment channels (5-10). This allows the water to pass through more magnetic field areas within the cavity, thereby enhancing the magnetic treatment effect and improving treatment efficiency. Zone C (outlet water collection zone) is similar to zone A, serving to divert and buffer the flow and reduce flow resistance. Zone C is located near the outlet, allowing the magnetically treated water to smoothly converge and discharge, while further balancing the water flow and preventing localized turbulence from affecting the effluent quality. Through this structural design, the water undergoes sufficient magnetic treatment and is discharged smoothly, effectively improving the overall performance and treatment efficiency of the magnetic treatment device.

[0092] Specific principles:

[0093] As shown in Figure 8-1, as the water flows from area A to area C, with the rotation of the magnetic treatment component 5 (regardless of whether the rotation direction is counterclockwise or clockwise), the water flow can repeatedly pass through the magnetic field region formed by the alternating arrangement of N and S poles, continuously being induced and treated by the magnetic field. Due to the rotation of the magnetic treatment component 5, the water flow can be repeatedly exposed to the alternating magnetic field environment as it flows through the magnetic treatment channels 5-10, thereby significantly enhancing the magnetic treatment effect. In addition, by appropriately increasing the rotational speed of the magnetic treatment component 5, not only can the frequency of magnetic field action be increased, achieving efficient reuse of the magnetic field, but the number of magnets can also be reduced while ensuring the treatment effect. This optimization measure helps to reduce the overall manufacturing cost of the device, while improving the economy and maintainability of the system.

[0094] As shown in Figure 8-1, when water containing ferromagnetic suspended microparticles enters the magnetic treatment channel 5-10, these microparticles are adsorbed onto the magnetic pole surface. However, since the magnetic pole surface of this device is always rotating at high speed, when the adsorbed particles rotate to the vicinity of area D (assuming the magnetic treatment component rotates counterclockwise), they will generate a reverse scouring effect with the water flow. Therefore, the ferromagnetic suspended microparticles will not continuously accumulate on the magnetic pole surface, avoiding the phenomenon of particles accumulating more and more, fundamentally solving the clogging problem, and further ensuring the magnetic treatment efficiency of the device.

[0095] As shown in Figure 8-2, water-retaining rings 3-5 are respectively provided at the upper and lower ends of the side baffle plate 3-6. The function of the water-retaining rings 3-5 is to prevent untreated water from flowing directly to the outlet 3-2 through the inner cavities of the upper cover assembly 2 and the lower cover assembly 4, thereby avoiding affecting the efficiency of magnetic treatment. The water-retaining rings 3-5 and the side baffle plate 3-6 cooperate with each other to effectively reduce the pressure fluctuation of the water inside the upper cover assembly 2 and the lower cover assembly 4, prevent a large amount of untreated water from escaping, and further improve and stabilize the magnetic treatment efficiency of the device.

[0096] During operation, water flows into the inlet buffer area through inlet 3-1, and is guided by side baffles 3-6 and baffle rings 3-5 to the magnetic treatment channel 5-10. Under the action of the rotating alternating magnetic field, charged ions undergo periodic deflection, and ferromagnetic particles are attracted by the magnetic poles and then flushed by the reverse water flow, preventing blockage. The treated water flows out through the outlet collection area and is discharged from outlet 3-2.

[0097] By adjusting the speed of motor 1-1 (adjustable speed motor), the rotation speed of magnetic treatment component 5 can be controlled to adapt to different water quality treatment needs; the electric drain valve at drain outlet 4-3 can periodically discharge impurities to ensure long-term efficient operation of the device.

[0098] In summary, this embodiment effectively solves the shortcomings of existing static magnetic field devices by using a multi-level coupled dynamic rotating magnetic field structure and adjustable speed rotation.

[0099] Second Embodiment

[0100] As shown in Figure 9, unlike Embodiment 1, the magnetic processing component has a multi-layer scalable structure, representing an improved design for processing devices with larger diameters.

[0101] As shown in Figures 9-1 and 9-2, the improved magnetic processing component 6 mainly includes the following components: annular magnet array 6-1, central shaft through hole 6-2, magnet fixing plate 6-3, magnetic guide plate 6-4, waterproof cover plate 6-5, limiting block 6-6, and magnetic processing channel 6-7.

[0102] The characteristics of the magnet array structure are as follows:

[0103] 1. The ring magnet array 6-1 is based on the central axis of the magnet fixing disk 6-3, and is arranged in multiple concentric circles along the circumference to achieve efficient spatial distribution of magnets.

[0104] 2. The number of magnet layers can be flexibly adjusted according to parameters such as the required processing capacity of the device and the specifications and dimensions of the magnets, so as to achieve dynamic matching.

[0105] 3. As shown in Figure 9-1, adjacent magnets in the same annular layer have the same specifications, and the magnetic pole faces are arranged alternately with N-S poles. The angle between adjacent magnetic pole faces is 180° and they cannot be placed opposite each other.

[0106] 4. The number of magnets in different ring layers can be set independently (equal or differentiated configurations can be selected), and different layers can use a variety of magnet shapes such as columnar or fan-shaped magnets.

[0107] 5. Magnet spacing requirements: On the magnet fixing plate 6-3, the minimum radial and circumferential spacing (d) of adjacent magnets must meet the proportional relationship of 1.2H≤d≤2H, where H is the axial height of the limiting block 6-6, which determines the gap of the magnetic field action zone of the magnetic processing channel 6-7.

[0108] 6. The geometry of the magnet is not limited and can be various structures such as cylindrical, sector, and polygonal.

[0109] Description of the structure and function of each component:

[0110] Central shaft through hole 6-2: Precisely drilled at the center of magnet fixing plate 6-3, used for drive shaft 1-9 to pass through, ensuring the coaxial rotation accuracy of the components.

[0111] Magnet fixing plate 6-3: It is made of non-magnetic materials (including but not limited to 316L stainless steel or ceramic-reinforced nylon) with precision machining. The plate surface has evenly distributed magnet mounting holes to achieve precise positioning and fixing of the annular magnet array 6-1.

[0112] Magnetic plate 6-4: A ring-shaped plate structure made of ferromagnetic material, coaxially nested with magnet fixing disk 6-3. Through magnetic adsorption, it forms a closed magnetic circuit with all magnets in the ring magnet array 6-1, integrating the discrete magnetic field into an axially penetrating magnetic field, reducing magnetic flux leakage and improving magnetic field utilization efficiency.

[0113] Waterproof cover plate 6-5: Made of the same material as the magnet fixing plate 6-3 (to take into account the coefficient of thermal expansion and electrochemical corrosion performance), equipped with multi-layer sealing rings (such as fluororubber O-rings), and fastened to the magnet fixing plate 6-3 by bolts to ensure overall sealing.

[0114] Limiting block 6-6: A cylinder made of the same material as the magnet fixing plate 6-3, with a channel in the center coaxial with the central shaft through hole 6-2. Its axial length (5-30mm) is used to adjust the height of the magnetic processing channel 6-7, thereby setting the distance between the two sets of magnet fixing plates.

[0115] Magnetic treatment channel 6-7: As shown in Figure 9-3, it is formed by the spacing between two sets of magnet fixing disks 6-3, constituting the axial magnetic field action zone. The magnetic field gradient direction in this region is perpendicular to the water flow direction. Its effective treatment volume (V) can be calculated by the following formula:

[0116] V=π(R2-r2)H

[0117] Where R is the outer radius of the magnetic plate, r is the outer radius of the limiting block, and H is the axial length of the limiting block.

[0118] This embodiment includes, but is not limited to, water treatment, as well as the treatment of other fluid media such as oil and gas.
