Description

Technical Field

[0001] This invention belongs to the field of water treatment equipment technology, and more specifically, relates to an electromagnetic water treatment device for preventing and removing scale. Background Technology

[0002] Electromagnetic water treatment equipment for scale prevention is a physical water treatment device that uses pulsed electromagnetic fields (PEF) or alternating electromagnetic fields (usually generated by permanent magnets or electromagnetic coils) to act on the water flowing through pipes in order to prevent and reduce the deposition of scale (mainly calcium carbonate CaCO3) on the surfaces of pipes, heat exchangers, boilers and other equipment.

[0003] The Chinese patent publication number is CN114933351A, which discloses an electromagnetic water treatment device for industrial scale prevention and removal. This invention greatly avoids the drawbacks caused by scale accumulation in pipes, which can lead to pipe blockage. At the same time, the electromagnetic water treatment device is easy to manufacture, reducing production costs. In addition, the solar energy storage panel can save energy consumption, and it is easy for staff to operate.

[0004] Existing electromagnetic water treatment equipment has the following disadvantages:

[0005] Magnetization region compatibility issues

[0006] Traditional electromagnetic water treatment equipment mostly uses a fixed winding coil method. After the coil is fixed, the position of the coil cannot be adjusted according to the specific structure of the pipeline and the scaling situation. In actual use, there are welds, bends and scaling areas in different locations on the pipeline. The fixed winding coil is difficult to adjust and will move to these special sections, resulting in the scale not being effectively magnetized and unable to meet the treatment needs of different pipeline sections.

[0007] The equipment is inconvenient to disassemble and assemble.

[0008] Existing electromagnetic water treatment equipment mostly uses an integral winding structure. When it is necessary to repair the pipeline or adjust the magnetization operation area, the process of completely dismantling and installing the coil is extremely cumbersome. This structure not only consumes a lot of time, but also cannot respond quickly and adjust the equipment in emergency scaling conditions, which seriously affects the efficiency of the equipment and results in insufficient handling capacity when dealing with emergencies.

[0009] Limitations of magnetic field regulation:

[0010] Existing electromagnetic water treatment equipment typically uses coils with fixed gaps, making real-time adjustment impossible based on actual operating conditions. When faced with varying water qualities (such as water with high calcium and magnesium content), different flow rates, and various harsh environments, the fixed magnetic field gradient and effective range are insufficient to meet the diverse needs for inducing mineral ion crystallization in water. For example, it cannot effectively accelerate crystal nucleation in high-hardness water, and it cannot meet the ion migration time requirements under high flow conditions. This results in insufficient precision in intervening in the crystallization morphology of mineral ions within the pipeline, making it impossible to maintain stable scale inhibition performance under complex operating conditions. Summary of the Invention

[0011] To address the aforementioned technical problems, this invention provides an electromagnetic water treatment device for preventing and removing scale, thereby resolving the problems described above.

The movable plate is located between the L-shaped pressure plate and the fixed plate. The wire-carrying rod is located on the fixed plate. At the lower end, a wire groove is formed at the lower end of the wire carrier rod. The upper coil group and the lower coil group are respectively fixedly installed on the inner side wall of the wire groove. A first movable groove is formed through the side end of the positioning plate. A first double-ended screw is rotatably installed through the inner side wall of the first movable groove. Side plates are fixedly installed on both sides of the positioning plate. A second movable groove is formed through the side end of each of the two side plates. A second double-ended screw is rotatably installed through the inner side wall of each of the two second movable grooves. Each arc-shaped locking rod is slidably installed on the inner side wall of the second movable groove. A first double-ended screw is formed through the upper end of each arc-shaped locking rod. The second double-ended screw is threadedly rotatably mounted on the inner wall of the second threaded groove. There are two L-shaped pressure plates, each with a mounting block fixedly mounted at its lower end. An adjusting screw is rotatably mounted between the two L-shaped pressure plates and the two mounting blocks. Two guide rods are fixedly mounted on the side ends of each of the two L-shaped pressure plates. An L-shaped movable rod is fixedly mounted on the lower end of each of the two L-shaped pressure plates. The two L-shaped movable rods are slidably mounted on the inner wall of the first movable groove. A first threaded groove is formed at the upper end of each of the two L-shaped movable rods. A double-ended screw is threaded through and installed on the inner sidewalls of two first threaded grooves. Two fixed plates are respectively fixedly installed on the side ends of the L-shaped pressure plate. A rectangular sliding groove is opened through the upper end of the fixed plate. Side rods are fixedly installed on both sides of the two movable plates. The two movable plates are slidably installed on the guide rods through the side rods. Multiple adjustment grooves are opened through the upper end of the two movable plates. T-shaped blocks are fixedly installed on the upper end of the two movable plates. A third threaded groove is opened through the side end of the two T-shaped blocks. The adjusting screw is threadedly rotatably installed on the inner sidewall of the third threaded groove.

[0013] Preferably, a column is fixedly installed at the upper end of each of the wire carrier poles, and each column is slidably installed through the inner side wall of each adjusting groove. Each column is slidably installed on the inner side wall of a rectangular groove. C-shaped rods are fixedly installed at both ends of each of the wire carrier poles, and positioning rings are fixedly installed at the side ends of each C-shaped rod.

[0014] Preferably, the lower end of the upper coil assembly has a ceramic insulating groove, the inner side wall of the ceramic insulating groove has a grounding groove, the upper end of the lower coil assembly has a sealing ring fixedly installed, and the upper end of the lower coil assembly also has a conductive plug fixedly installed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, by providing a positioning plate with adjustable position and an arc-shaped locking rod, the coil can be moved along the axial direction of the pipe during the electromagnetic treatment of scale. The operator can accurately adjust the coverage of the upper and lower coil groups according to the location of welds, bends or known scale areas on the pipe. Compared with the traditional fixed winding method, the adaptability of magnetization treatment for different sections of the pipe is improved, avoiding magnetic field blind spots caused by installation position deviations and improving magnetization efficiency.

[0017] In this invention, a split coil design is provided, and the upper and lower coil halves are quickly separated and coupled through the interface plug-in at the upper and lower coil groups. When it is necessary to inspect the pipeline or adjust the magnetization operation area, the upper and lower coil groups can be disconnected to release the operating space. Compared with the traditional integral winding structure, it can significantly save disassembly and assembly time, improve the response efficiency of this device in emergency scaling conditions, and make the equipment more efficient.

[0018] In this invention, a three-layer protective structure is formed by combining a sealing ring, a conductive plug, a ceramic insulating groove, and a grounding groove: the sealing ring blocks moisture, the ceramic insulating groove isolates high-voltage arcs, and the conductive plug connects to the grounding groove to ensure current conduction. This ensures that the upper and lower coil groups maintain a stable electrical connection during frequent disassembly and assembly, avoiding magnetic field fluctuations or leakage risks caused by poor contact. It achieves flexible adjustment of magnetization while ensuring the safety of equipment use.

[0019] In this invention, by using an upper coil group and a lower coil group with adjustable gaps, the crystallization induction efficiency of mineral ions in water can be directly affected by changing the magnetic field gradient and range of action. When the gap narrows, the magnetic field strength near the pipe is enhanced, accelerating the formation of crystal nuclei in high-hardness water. When the gap widens, the depth of magnetic field action is extended, adapting to the ion migration time requirements under high flow rates. This allows the range and intensity of the electromagnetic field to be optimized in real time according to the operating conditions, improving the precision of intervention on the crystallization morphology of mineral ions in the pipe, thereby maintaining a more stable scale inhibition performance under variable flow rates, high calcium and magnesium, and harsh environments.

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Please see Figure 1 - Figure 9This invention provides an electromagnetic water treatment device for scale removal, comprising a positioning plate 1 and a pipe 8. The positioning plate 1 is equipped with an adjustment mechanism for adjusting the position of the pipe 8 during treatment, and a movable mechanism for facilitating pipe 8 treatment. The adjustment mechanism includes an arc-shaped locking rod 16, an L-shaped pressure plate 2, a fixed plate 3, and a movable plate 4. The movable mechanism includes a wire-carrying rod 5, an upper coil group 6, and a lower coil group 7. When water is being transported, the water flowing through the pipe 8, when the water temperature rises or the pressure changes, releases dissolved calcium and magnesium ions and carbonate / bicarbonate ions. Combined with precipitation, hard calcium carbonate and other crystals are deposited on the inner wall of pipe 8, gradually accumulating into scale. When treating the scale in pipe 8, the positioning plate 1 is fixed to the circumferential end of pipe 8 by the arc-shaped locking rod 16, and the upper coil group 6 and lower coil group 7 on both sides are adjusted to connect. The ends of the lower coil group 7 and upper coil group 6 are fixed on the high-frequency power control cabinet. It induces scale-forming ions in water to form a large number of loose aragonite crystals rather than dense calcite crystals through electromagnetic field. These aragonite crystals are carried away by the water flow, thereby preventing scale from depositing on the surface of the equipment.

[0032] An arc-shaped locking rod 16 is located at the side end of the positioning plate 1. An L-shaped pressure plate 2 is slidably located at the side end of the positioning plate 1. A fixed plate 3 is located at the lower end of the L-shaped pressure plate 2. A movable plate 4 is located between the L-shaped pressure plate 2 and the fixed plate 3. A wire-carrying rod 5 is located at the lower end of the fixed plate 3. A wire groove 52 is provided at the lower end of the wire-carrying rod 5. The upper coil group 6 and the lower coil group 7 are respectively fixedly installed on the inner side wall of the wire groove 52. A first movable groove 11 is provided through the side end of the positioning plate 1. A first double-headed screw 12 is rotatably installed through the inner side wall of the first movable groove 11. Side plates 13 are fixedly installed on both sides of the positioning plate 1. A second movable groove 14 is provided through the side end of each of the two side plates 13. A second double-headed screw 15 is rotatably installed through the inner side wall of each of the two second movable grooves 14. Each arc-shaped locking rod 16 is slidably installed on the inner side wall of the second movable groove 14. A wire groove 52 is provided through the upper end of each arc-shaped locking rod 16. There is a second threaded groove 17, and each second double-ended screw 15 is screwed and rotated on the inner side wall of the second threaded groove 17. When fixing the equipment, the user can engage the arc-shaped locking rods 16 on both sides with the circumferential end of the pipe 8, so that the upper coil group 6 and the lower coil group 7 are aligned with the part on the pipe 8 that needs to be magnetized. After the alignment is completed, the user can rotate the two second double-ended screws 15. The second double-ended screws 15 rotate and drive the arc-shaped locking rods 16 on both sides to move closer to each other through the second threaded groove 17, so that the arc-shaped locking rods 16 on both sides clamp the pipe 8 and realize the positioning of the positioning plate 1. When it is necessary to change or adjust the position of the upper coil group 6 and the lower coil group 7, release the engagement of the upper coil group 6 and the lower coil group 7, and at the same time rotate the second double-ended screw 15 in the opposite direction to drive the arc-shaped locking rods 16 away from each other, so that the clamping and locking can be engaged, the position of the positioning plate 1 can be adjusted and replaced, and then clamping can be performed again.

[0033] There are two L-shaped pressure plates 2. Each L-shaped pressure plate 2 has a mounting block 21 fixedly installed at its lower end. An adjusting screw 22 is rotatably installed between each L-shaped pressure plate 2 and each mounting block 21. Two guide rods 23 are fixedly installed at the side ends of each L-shaped pressure plate 2. An L-shaped movable rod 24 is fixedly installed at the lower end of each L-shaped pressure plate 2. The two L-shaped movable rods 24 are slidably installed on the inner wall of the first movable groove 11. A first threaded groove 25 is formed at the upper end of each L-shaped movable rod 24. The first double-ended screw 12 is threaded through and installed on the inner sidewalls of the two first threaded grooves 25. Two fixed plates 3 are respectively fixedly installed on the side ends of the L-shaped pressure plate 2. A rectangular sliding groove 31 is provided through the upper end of each fixed plate 3. Side rods 41 are fixedly installed on both sides of each of the two movable plates 4. The two movable plates 4 are slidably installed on the guide rod 23 via the side rods 41. Multiple adjusting grooves 42 are provided through the upper end of each of the two movable plates 4. T-shaped blocks 43 are fixedly installed on the upper end of each of the two movable plates 4. The side ends of the T-shaped block 43 are all provided with a third threaded groove 45. The adjusting screw 22 is screwed and rotated on the inner wall of the third threaded groove 45. Before the upper coil group 6 and the lower coil group 7 are snapped together, the user can also adjust the gap between the upper coil group 6 and the lower coil group 7 according to the flow rate in the pipe 8, the change in water hardness in the pipe 8 and the actual working environment of the pipe 8. When adjusting the gap between the upper coil group 6 or the lower coil group 7, the user can rotate the adjusting screw 22. The rotation of the adjusting screw 22 drives the T-shaped block 43 to move through the third threaded groove 45. The movement of the T-shaped block 43 will drive the movable plate 4 to move. When the movable plate 4 slides on the fixed plate 3, it will drive each column 51 to slide away from each other through the adjusting groove 42. The movement of the columns 51 away from each other will synchronously drive the upper coil group 6 to move away from each other. After the adjustment of the upper coil group 6 is completed, the user can synchronously rotate the adjusting screw 22 located below to synchronously adjust the gap of the lower coil group 7, thereby realizing the synchronous adjustment of the gap between the upper coil group 6 and the lower coil group 7.

[0034] Each wire carrier rod 5 has a fixed column 51 at its upper end. Each column 51 is slidably installed through the inner wall of each adjusting groove 42. Each column 51 is slidably installed on the inner wall of the rectangular slide groove 31. C-shaped rods 53 are fixedly installed at both ends of each wire carrier rod 5. Positioning rings 54 are fixedly installed at the side ends of each C-shaped rod 53. After adjusting the position of the positioning plate 1, the upper coil group 6 and the lower coil group 7 can be connected. The user can rotate the first double-ended screw 12. The rotation of the first double-ended screw 12 drives the L-shaped movable rods 24 on both sides to move closer to each other through the first threaded groove 25. The movement of the L-shaped movable rods 24 on both sides drives the L-shaped pressure plates 2 on both sides to move closer to each other. The movement of the L-shaped pressure plates 2 on both sides drives the fixed plates 3 and movable plates 4 on both sides to move closer to each other, thereby making the two The side wire carrier rods 5 move closer to each other, and the upper coil group 6 and the lower coil group 7 are respectively embedded in the wire grooves 52 of the two side wire carrier rods 5. When the two side wire carrier rods 5 move closer to each other, the upper coil group 6 and the lower coil group 7 on both sides will approach each other and attach to the pipe 8. The positioning rings 54 on the C-shaped rods 53 on both sides will drive the upper coil group 6 and the lower coil group 7 on both sides to engage with each other, so that the sealing ring 71 is embedded into the inner wall of the ceramic insulating groove 61, and the conductive plug 72 is embedded into the inner wall of the electrical connection groove 62, thereby realizing the connection between the upper coil group 6 and the lower coil group 7. At this time, the user can fix the ends of the lower coil group 7 and the upper coil group 6 on the high-frequency power control cabinet. The scale-forming ions are induced by the electromagnetic field to form loose crystals in the water. These aragonite crystals are carried away by the water flow, thereby preventing scale from depositing on the inner wall of the pipe 8.

[0035] The lower end of the upper coil group 6 is provided with a ceramic insulating groove 61, and the inner side wall of the ceramic insulating groove 61 is provided with a current receiving groove 62. The upper end of the lower coil group 7 is fixedly installed with a sealing ring 71, and the upper end of the lower coil group 7 is also fixedly installed with a conductive plug 72. The sealing ring 71 blocks water vapor, the ceramic insulating groove 61 isolates high voltage arc, and the conductive plug 72 is connected to the current receiving groove 62 to ensure current conduction. This allows the upper coil group 6 and the lower coil group 7 to maintain a stable electrical connection during frequent disassembly and assembly, avoiding magnetic field fluctuations or leakage risks caused by poor contact. This ensures the safety of equipment use while flexibly adjusting the magnetization effect.

[0036] Working principle:

[0037] The first step involves the following process: When water is being transported, the water flowing through pipe 8 experiences temperature increases or pressure changes. Dissolved calcium and magnesium ions in the water combine with carbonate / bicarbonate ions and precipitate out, forming hard calcium carbonate crystals that deposit on the inner wall of pipe 8, gradually accumulating into scale. When treating the scale in pipe 8, the positioning plate 1 is fixed to the circumferential end of pipe 8 using the arc-shaped locking rod 16. The upper coil group 6 and lower coil group 7 on both sides are then connected by insertion. The ends of the lower coil group 7 and upper coil group 6 are fixed to the high-frequency power control cabinet. This process induces scale-forming ions in the water to form a large number of loose aragonite crystals rather than dense calcite crystals. These aragonite crystals are carried away by the water flow, thus preventing scale from depositing on the equipment surface.

[0038] The second step involves fixing the equipment. The user can engage the two arc-shaped locking rods 16 on the circumferential ends of the pipe 8, aligning the upper coil group 6 and the lower coil group 7 with the parts of the pipe 8 that need to be magnetized. After alignment, the user can rotate the two second double-ended screws 15. The second double-ended screws 15 rotate through the second threaded groove 17 to bring the two arc-shaped locking rods 16 closer together, clamping the pipe 8 and positioning the positioning plate 1. When it is necessary to change or adjust the position of the upper coil group 6 and the lower coil group 7, release the engagement of the upper coil group 6 and the lower coil group 7, and simultaneously rotate the second double-ended screws 15 in the opposite direction to move the arc-shaped locking rods 16 away from each other, thus engaging the clamping and locking mechanism. The position of the positioning plate 1 can then be adjusted or replaced, and clamping can be performed again.

[0039] This device, by setting up a position-adjustable positioning plate 1 and an arc-shaped locking rod 16, can achieve the displacement of the coil along the axial direction of the pipe 8 during the electromagnetic treatment of scale. The operator can precisely adjust the coverage of the upper coil group 6 and the lower coil group 7 according to the location of the weld, elbow or known scale area on the pipe 8. Compared with the traditional fixed winding method, the adaptability of magnetization treatment for different sections of the pipe 8 is improved, avoiding the magnetic field blind zone caused by the installation position deviation and improving the magnetization efficiency.

[0040] The third step, after adjusting the position of the positioning plate 1, is to connect the upper coil group 6 and the lower coil group 7. The user can rotate the first double-ended screw 12. The rotation of the first double-ended screw 12, through the first threaded groove 25, causes the L-shaped movable rods 24 on both sides to move closer together. The movement of the L-shaped movable rods 24 causes the L-shaped pressure plates 2 on both sides to move closer together. The movement of the L-shaped pressure plates 2 causes the fixed plates 3 and movable plates 4 on both sides to move closer together, thereby causing the wire carrier rods 5 on both sides to move closer together. The upper coil group 6 and the lower coil group 7 are respectively embedded in the wire grooves 52 of the wire carrier rods 5 on both sides. As the wire carrier rods 5 on both sides move closer together... When they approach each other, the upper coil group 6 and the lower coil group 7 on both sides will move closer to each other and attach to the pipe 8. The positioning rings 54 on the C-shaped rods 53 on both sides will drive the upper coil group 6 and the lower coil group 7 on both sides to engage with each other, so that the sealing ring 71 is embedded into the inner wall of the ceramic insulating groove 61, and the conductive plug 72 is embedded into the inner wall of the electrical connection groove 62, thereby realizing the connection between the upper coil group 6 and the lower coil group 7. At this time, the user can fix the ends of the lower coil group 7 and the upper coil group 6 on the high-frequency power control cabinet. The electromagnetic field induces scale-forming ions to form loose crystals in the water. These aragonite crystals are carried away by the water flow, thereby preventing scale from depositing on the inner wall of the pipe 8.

[0041] This device features a split coil design, allowing for rapid separation and coupling of the upper and lower coil halves via interfaces at the upper coil group 6 and lower coil group 7. When it is necessary to inspect the pipeline 8 or adjust the magnetization operation area, disconnecting the upper coil group 6 and lower coil group 7 will free up operating space. Compared with the traditional integral winding structure, this significantly saves disassembly and assembly time, improves the device's response efficiency in emergency scaling conditions, and makes the equipment more efficient.

[0042] This device forms a three-layer protective structure by combining a sealing ring 71, a conductive plug 72, a ceramic insulating groove 61, and a power receiving groove 62. The sealing ring 71 blocks moisture, the ceramic insulating groove 61 isolates high-voltage arcs, and the conductive plug 72 connects to the power receiving groove 62 to ensure current conduction. This allows the upper coil group 6 and the lower coil group 7 to maintain a stable electrical connection during frequent disassembly and assembly, avoiding magnetic field fluctuations or leakage risks caused by poor contact. It achieves flexible adjustment of magnetization while ensuring the safety of equipment use.

[0043] Fourthly, before connecting the upper coil group 6 and the lower coil group 7, the user can adjust the gap between the upper coil group 6 and the lower coil group 7 according to the flow rate in the pipe 8, the change in water hardness in the pipe 8, and the actual working environment of the pipe 8. When adjusting the gap between the upper coil group 6 or the lower coil group 7, the user can rotate the adjusting screw 22. The rotation of the adjusting screw 22 drives the T-block 43 to move through the third threaded groove 45. The movement of the T-block 43 will drive the movable plate 4 to move. When the movable plate 4 slides on the fixed plate 3, it will drive each column 51 to slide away from each other through the adjusting groove 42. The movement of the columns 51 away from each other will synchronously drive the upper coil group 6 to move away from each other. After the adjustment of the upper coil group 6 is completed, the user can synchronously rotate the adjusting screw 22 located below to synchronously adjust the gap of the lower coil group 7, thereby realizing the synchronous adjustment of the gap between the upper coil group 6 and the lower coil group 7.

[0044] This device, by setting up an upper coil group 6 and a lower coil group 7 with adjustable gaps, directly affects the crystallization induction efficiency of mineral ions in water by changing the magnetic field gradient and range of action. When the gap narrows, the magnetic field strength near the pipe 8 is enhanced, accelerating the formation of crystal nuclei in high-hardness water. When the gap widens, the depth of magnetic field action is extended, adapting to the ion migration time requirements under high flow rates. This allows the range and intensity of the electromagnetic field to be optimized in real time according to the operating conditions, improving the precision of intervention on the crystallization morphology of mineral ions in the pipe 8, thereby maintaining a more stable scale inhibition performance under variable flow rates, high calcium and magnesium, and harsh environments.

[0045] This device uses a fixed plate 3 and a movable plate 4 in combination. By rotating the adjusting screw 22, the movable plate 4 slides on the fixed plate 3, thereby synchronously moving each wire rod 5. This allows for the adjustment of the gap between the upper coil group 6 and the lower coil group 7. It eliminates the need to adjust the upper coil group 6 and the lower coil group 7 individually, making the adjustment method simple and efficient. This enables highly efficient matching and response to the magnetization of dirt in different environments.
