Description

Technical Field

[0001] This invention relates to the field of wastewater treatment engineering technology, specifically to a high-frequency electromagnetic scale inhibition technology and method for wastewater treatment. Background Technology

[0002] During the operation of a wastewater treatment system, wastewater contains a large amount of calcium and magnesium ions and microorganisms, which can easily cause scaling, biological slime adhesion, and pipe wall corrosion and blockage in water transmission pipelines, directly reducing wastewater transportation efficiency and system operation stability. Therefore, scale inhibition and corrosion prevention in pipeline networks are an important part of the wastewater treatment field.

[0003] Current methods for scale inhibition in pipe networks mainly rely on chemical agent dosing processes, using scale inhibitors, corrosion inhibitors, and bactericides to protect pipelines. However, continuous consumption of these agents can easily lead to secondary water pollution, increase the load on wastewater treatment and make sludge disposal more difficult. Furthermore, the numerous supporting equipment and complex installation and maintenance processes do not align with current water treatment development trends. While traditional high-frequency electronic descaling equipment does not require the use of chemicals, it mostly performs localized treatment at fixed points with limited effective range. Pipelines far from electronic descaling equipment are still prone to scale buildup, and old scale removal is slow. In addition, the installation and dismantling of traditional high-frequency electronic descaling equipment often requires cutting off pipes, disassembling pipe flanges, and shutting down water supply, resulting in excessively long installation and dismantling times and reduced construction efficiency.

[0004] Furthermore, when traditional electronic descaling equipment descales some old pipes, the scale inside the pipes adheres firmly to the pipe walls. If pretreatment is not performed, it is difficult for high-frequency electronic descaling equipment to quickly remove the scale or remove it completely. At the same time, there is a lack of detection components to detect the scale removal effect, making it impossible to promptly identify areas that have not been cleaned and carry out secondary cleaning operations. These problems lead to low construction efficiency, poor sewage treatment effect, and complex installation and maintenance in sewage treatment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A high-frequency electromagnetic scale inhibition technology for wastewater treatment includes an electric trolley, an electromagnetic descaling main control unit, and a battery.

[0007] A further improvement of the technical solution of the present invention is that: adjustable distance components are provided on both sides of the top of the mounting base. The adjustable distance components include a clamping seat one, a clamping seat two, a rod groove, a bidirectional threaded rod, and a motor one.

The motor one is fixed to the surface of one end of the mounting base. One end of one of the bidirectional threaded rods passes through the mounting base and is fixed to the output end of the motor one. The battery and the motor one are electrically connected.

[0008] A further improvement of the technical solution of the present invention is that: the adjusting assembly further includes a synchronous pulley and a synchronous belt, the synchronous pulley is fixedly sleeved at one end of the outer circumferential surface of the two bidirectional threaded rods, and the synchronous belt is sleeved between the two synchronous pulleys.

[0009] A further improvement of the technical solution of the present invention is that a driving assembly is connected between the clamping seat one and the clamping seat two. The driving assembly includes a fixed seat, a motor two, a rotating shaft, a gear one, a gear ring one, and a gear ring two. The fixed seat is fixed to one side of one of the clamping seats one and one of the clamping seats two. The motor two is fixed to the surface of one of the fixed seats. The rotating shaft is fixed to the output end of the motor two. The rotating shaft is rotatably connected to the inner wall of the fixed seat. The gear one is fixedly sleeved on both sides of the outer circumference of the rotating shaft. The gear ring one is slidably inserted at the middle position of the two clamping seats one. The gear ring two is slidably inserted inside the two clamping seats two. The two gears one are respectively meshed with the adjacent gear ring one and gear ring two. The motor two is electrically connected to the battery.

[0010] A further improvement of the technical solution of the present invention is that: a pre-processing component is connected to the inner circumferential surface of the gear ring one. The pre-processing component includes a protrusion, a sliding rod, a contact block, a spring, and an impact head. Multiple protrusions are fixed at multiple positions on the inner circumferential surface of the gear ring one. Two sliding rods are slidably inserted into the inner wall of the gear ring one. The contact block is fixed at one side of the sliding rod. The impact head is fixed at the other side of the sliding rod. The spring is sleeved on the outer circumferential surface of the sliding rod. One side of the protrusion and the contact block is arc-shaped. The side of the impact head away from the adjacent contact block is arc-shaped. One side of the spring is fixed to the surface of the adjacent contact block. The other side of the spring is fixed to the inner wall of the gear ring one.

[0011] A further improvement of the technical solution of the present invention is that the pretreatment component further includes an annular opening, a fixed rod, a vibration motor, and an arc-shaped contact plate. The annular opening is located on the inner wall of the gear ring at the middle position of the two sliding rods. The fixed rod is fixed to the inner circumferential surface of the gear ring near the annular opening. The fixed rod and the annular opening are slidably inserted together. The vibration motor is fixed to one end of the fixed rod. The arc-shaped contact plate is fixed to the surface of one side of the vibration motor. The vibration motor and the battery are electrically connected.

[0012] A further improvement of the technical solution of the present invention is that: the inner wall of the second gear ring is connected to a detection component, the detection component includes an infrared thermal imaging temperature measurement probe and a heating plate, the infrared thermal imaging temperature measurement probe is fixed at one of the inner circumferential surfaces of the second gear ring, the heating plate is fixed at both ends of the inner circumferential surface of the second gear ring located at both ends of the infrared thermal imaging temperature measurement probe, and the infrared thermal imaging temperature measurement probe is electrically connected to the heating plate and the battery.

[0013] A further improvement of the technical solution of the present invention is that the detection component further includes a gear ring three, a brush rod and a gear two. The gear ring three is fixed at the inner side of the two clamps two. The brush rod is rotatably connected to the inner circumferential surface of another gear ring two. The gear two is fixedly sleeved on the outer circumferential surface of the brush rod. The gear two and the gear ring three are meshed together.

[0014] A high-frequency electromagnetic scale inhibition method for wastewater treatment includes the following steps: Step 1: Check the integrity of each component of the device, ensure that the battery is fully charged, the power-consuming part is in normal standby state, and that the fiberglass insulation tape, bolts, fasteners and other accessories are complete. Control the electric trolley to move to the bottom of the pipe that needs to be descaled, adjust the position of the electric trolley to ensure that the mounting base and the upper part are aligned with the bottom of the pipe, so as to facilitate the subsequent clamping of the pipe. Step 2: Start the hydraulic cylinder so that the output end of the hydraulic cylinder drives the mounting base to rise vertically until the electromagnetic descaling component at the top of the mounting base moves to a height that can cover the outer circumference of the pipe. Then, turn off the hydraulic cylinder and lock the position. Step 3: Insert the male circuit connector at one end of the top of the electromagnetic coil into the female circuit connector at the other end, so that the magnetic contact pieces of the two are in contact with each other, and splice the electromagnetic coil into a complete ring. At the splicing point of the male circuit connector and the female circuit connector, glue fiberglass insulating tape to ensure that the high-frequency magnetic flux circuit is complete and there is no magnetic field leakage. Step 4: Start motor 1 to make the two bidirectional threaded rods rotate synchronously, so that clamp 1 and clamp 2 move towards each other until the two sets of clamp 1 fit with the gear ring 1 and the two sets of clamp 2 fit with the gear ring 2, forming a complete ring and wrapping the pipe. Step 5: Start the vibration motor and motor 2, so that the vibration motor and the arc-shaped contact plate are in circular motion against the outer circumference of the pipe. The slight vibration generated by the vibration motor is transmitted to the pipe through the arc-shaped contact plate, which loosens the base bonding force of the scale on the inner wall of the pipe. The pretreatment time is adjusted according to the thickness of the scale layer in the pipe. The protrusions contact the contact block through the arc-shaped surface, so that the impact head repeatedly knocks on the outer wall of the pipe, preparing for the subsequent electromagnetic descaling. Step Six: Start the electromagnetic descaling main control unit, control the electromagnetic coil to generate an alternating electromagnetic field, control the electric trolley to slide along the outer circumference of the pipeline, drive the electromagnetic descaling components to move synchronously, and gradually expand the range of the high-frequency alternating electromagnetic field and the pretreatment range of the pipeline. Step 7: Pre-start the heating plate. The heating plate rotates with the gear ring to make a circular motion, which heats the outer circumference of the pipe evenly. The temperature of the inner and outer walls of the pipe is observed by an infrared thermal imaging temperature measurement probe. During the heating of the pipe, iron filings, dust and other impurities on the outer wall of the pipe are cleaned by a brush rod to ensure uniform heating in the future. Step 8: After the designated area of ​​the pipeline has been completely treated and passed the inspection, turn off all electrical equipment, loosen the bolts and fasteners, open the clamps, start the hydraulic cylinder to lower the mounting base and electromagnetic descaling components to the initial position, and control the electric trolley to move to the next section of the pipeline to be treated, or to the designated storage location to complete the operation.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: This invention applies a high-frequency alternating electromagnetic field to the polluted water inside the pipeline using an electromagnetic descaling main control unit and an electromagnetic descaling component. Under the action of the high-frequency alternating electromagnetic field, the hydrogen bonds of water molecules in the sewage are broken to form small water molecule clusters, which encapsulate scale-forming ions such as calcium and magnesium, inhibiting the formation of dense scale and promoting the shedding of old scale. Furthermore, the electromagnetic descaling main control unit and the electromagnetic descaling component can slide along the outer circumference of the pipeline with the gap of the electric trolley, gradually adjusting the range of action of the high-frequency alternating electromagnetic field, thereby achieving multi-location treatment. This avoids the limited range of action of fixed-point treatment, where pipelines far from the electronic descaling equipment are still prone to scaling or slow removal of old scale. Moreover, during installation and disassembly, the electromagnetic descaling component can be installed on the outer circumference of the pipeline without cutting off the pipeline, disassembling the pipeline flange, or shutting down the water supply, thus shortening the installation time and improving construction efficiency.

[0016] This invention utilizes a pretreatment component. Under the vibration force generated by repeated impacts of an impact head on the outside of the pipe at the front end of the electromagnetic coil, the dense, old scale shell adhering to the inside of the pipe wall can be cracked. This loosens the adhesion between the scale and the metal pipe wall, creating pores within the scale layer and breaking down the scale's sealing barrier. Furthermore, when treating pipes that have been in use for a long time, a vibration motor can uniformly apply micro-vibrations to the position where the arc-shaped contact plate contacts the pipe. The micro-vibrations transmitted by the arc-shaped contact plate can reduce the adhesion of scale on the inner wall of the pipe after long-term use and destroy the adhesion of the scale layer, providing favorable conditions for the subsequent impact head to peel off the scale layer and improving the efficiency of scale removal.

[0017] This invention uses a toothed ring to wrap around the pre-treated and electromagnetically treated pipe. After the heating plate evenly heats the pipe contact area, an infrared thermal imaging temperature probe is used to observe the temperature of the inner and outer walls of the pipe to determine whether there is still scale inside the pipe. Secondary treatment can be performed on the scale residue to ensure the sewage treatment effect. During the heating process, one side of the brush rod can fit against the outer wall of the pipe and make a circular motion while rotating, so that iron filings, dust and other impurities adhering to a certain circumferential range on the outer wall of the pipe are cleaned by the brush rod. This further ensures that the heating plate heats the pipe evenly and fully to improve the detection accuracy. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to embodiments: Example 1, First aspect, such as Figures 1-9As shown, the present invention provides a high-frequency electromagnetic scale inhibition technology for sewage treatment, including an electric trolley 1, an electromagnetic descaling main control unit 2, and a battery 3. Hydraulic cylinders 5 are fixed at the four corners of the top of the electric trolley 1. The output ends of the multiple hydraulic cylinders 5 are fixed with mounting bases 4. An electromagnetic descaling component is connected at the middle position of the top of the mounting base 4. The electromagnetic descaling main control unit 2 and the battery 3 are fixed at the two sides of the top of the electric trolley 1. The battery 3 is electrically connected to the electric trolley 1, the electromagnetic descaling main control unit 2, and the hydraulic cylinders 5.

[0021] The electric trolley 1 is controlled to move to the bottom of the pipe requiring descaling. Hydraulic cylinder 5 is activated, causing mounting base 4 to move vertically, allowing the electromagnetic descaling component to wrap around the pipe. Adjusting the electromagnetic descaling component ensures it effectively wraps around the pipe. With the combined operation of the main control unit 2 and the electromagnetic descaling component, an alternating electromagnetic field of 20kHz-500kHz is generated. This field acts on the polluted water inside the pipe, breaking the hydrogen bonds of water molecules to form small water molecule clusters. It also encapsulates scale-forming ions such as calcium and magnesium, inhibiting the formation of dense scale and promoting the removal of old scale. The process involves breaking down the cell membrane potential of microorganisms and forming a protective rust film on the metal pipe wall. This overcomes the low-frequency limitations of traditional physical scale inhibition, breaks the hydrogen bonds of water molecules to convert large water clusters into small water clusters, and strengthens the encapsulation and inhibition of calcium and magnesium scale-forming ions. This achieves integrated synergistic functions of scale prevention, scale removal, sterilization, algae removal, and corrosion prevention. Meanwhile, the electromagnetic descaling main control unit 2 and the electromagnetic descaling components can slide along the outer circumference of the pipe with the gap of the electric trolley 1, gradually adjusting the range of action of the high-frequency alternating electromagnetic field. This enables multi-location treatment, avoiding the limited range of action of fixed-point treatment, where pipe networks far from the electronic descaling equipment are still prone to scale formation or slow removal of old scale.

[0022] The electromagnetic descaling assembly includes support bases 6, clamps 7, electromagnetic coils 8, bolts 9, male circuit connectors 10, female circuit connectors 11, magnetic contact plates 12, and fiberglass insulating tape 13. Multiple support bases 6 are fixed to the middle position of the top surface of the mounting base 4. The clamps 7 are rotatably connected to the top position of the support bases 6. The electromagnetic coils 8 are fixed to the inner walls of two clamps 7. The bolts 9 are threadedly connected to the top positions of the two clamps 7. Multiple male circuit connectors 10 are fixed to the electromagnetic coils 8. At one end, multiple male circuit connectors 10 are fixed to the other end of the electromagnetic coil 8. The male circuit connectors 10 and the female circuit connectors 11 are mating tenon joints. The magnetic contact piece 12 is fixed to the surface of the male circuit connectors 10 and the inner wall of the female circuit connectors 11. Fiberglass insulating tape 13 is glued to the surfaces of the male circuit connectors 10 and the female circuit connectors 11 at the points where they are in contact. The electromagnetic coil 8 and the electromagnetic descaling main control unit 2 are electrically connected.

[0023] After the hydraulic cylinder 5 raises the clamp 7 to the appropriate height for wrapping the pipe, the two clamps 7 are rotated towards each other and connected by bolts 9. Since the bottom of the electromagnetic coil 8 is connected but the top is not, the male connector 10 connected at one end of the top of the electromagnetic coil 8 is inserted into the female connector 11 connected at the other end of its top, so that the two adjacent magnetic contact pieces 12 are in contact with each other. This adjusts the electromagnetic coil 8 into a complete ring structure to complete the high-frequency magnetic flux circuit, making the ring magnetic field complete and uniform. The male connector at the top of the electromagnetic coil 8 is then connected. The splice of the female plug socket 11 and the circuit connection is wrapped with adhesive fiberglass insulating tape 13, which further improves the integrity of the annular magnetic field of the electromagnetic coil 8. When the electromagnetic descaling main control host 2 powers the electromagnetic coil 8, the electromagnetic coil 8 can apply a high-frequency alternating electromagnetic field to the pipeline. During this process, the gap between the tops of the bolts and fasteners 9 can be reduced by the bolts and fasteners 9, so that the electromagnetic coil 8 can fully fit the outer circumference of the pipeline to ensure the effect. Thus, the electromagnetic descaling component can be installed on the outer circumference of the pipeline without cutting off the pipeline, disassembling the pipeline flange, or shutting down the water supply, thereby shortening the installation time and improving the construction efficiency.

[0024] In embodiment 2, a second aspect, the top of the mounting base 4 is provided with two sides of an adjustable assembly. The adjustable assembly includes a clamp 14, a clamp 25, a rod groove 16, a bidirectional threaded rod 17, a motor 18, a synchronous pulley 19, and a synchronous belt 20. The rod groove 16 is opened on both sides of the top of the mounting base 4. The bidirectional threaded rod 17 is rotatably connected to the inner cavity of the two rod grooves 16. The two clamps 14 are threaded to the middle position of the outer peripheral surface of one of the bidirectional threaded rods 17. The two clamps 25 are threaded to the middle position of the outer peripheral surface of the other bidirectional threaded rod 17. The motor 18 is fixed to the surface of one end of the mounting base 4. The synchronous pulley 19 is fixedly sleeved on one end of the outer peripheral surface of the two bidirectional threaded rods 17. The synchronous belt 20 is sleeved between the two synchronous pulleys 19. One end of one of the bidirectional threaded rods 17 passes through the mounting base 4 and is fixed to the output end of the motor 18. The battery 3 and the motor 18 are electrically connected.

[0025] By starting the motor 18, one of the bidirectional threaded rods 17 is rotated. Under the connection of the synchronous pulley 19 and the synchronous belt 20, the two bidirectional threaded rods 17 rotate synchronously. Since the external thread structures at both ends of the outer circumference of the bidirectional threaded rods 17 are set in opposite directions, and the clamp 14 and clamp 25 can be resisted and limited by the inner wall of the rod groove 16, the clamp 14 can move towards each other or away from each other.

[0026] A drive assembly is connected between clamp 14 and clamp 25. The drive assembly includes a fixed base 21, a second motor 22, a rotating shaft 23, a first gear 24, a first gear ring 25, and a second gear ring 33. The fixed base 21 is fixed to one side of one of the clamps 14 and clamp 25. The second motor 22 is fixed to the surface of one of the fixed bases 21. The rotating shaft 23 is fixed to the output end of the second motor 22. The rotating shaft 23 is rotatably connected to the inner wall of the fixed base 21. The first gear 24 is fixedly sleeved on both sides of the outer circumference of the rotating shaft 23. The first gear ring 25 is slidably inserted in the middle of the two clamps 14. The second gear ring 33 is slidably inserted in the inside of the two clamps 25. The two first gears 24 are meshed with the adjacent first gear ring 25 and second gear ring 33, respectively. The second motor 22 and the battery 3 are electrically connected. When clamp 14 and clamp 25 move toward each other until the two sets of clamp 14 and gear ring 25 are in contact, and the two sets of clamp 25 and gear ring 23 are in contact to form a complete ring structure that wraps around the pipe, then the rotating shaft 23 is rotated by starting motor 22, which in turn drives the two gears 1 24 to rotate. Under the meshing action between one gear 1 24 and gear ring 25, and under the meshing action between the other gear 1 24 and gear ring 23, the two sets of gear rings 1 25 and gear ring 2 33 that are spliced ​​together can rotate.

[0027] A pre-treatment assembly is connected to the inner circumferential surface of the gear ring 25. The pre-treatment assembly includes a protrusion 26, a sliding rod 27, a contact block 28, a spring 29, and an impact head 30. Multiple protrusions 26 are fixed at multiple positions on the inner circumferential surface of the gear ring 25. Two sliding rods 27 are slidably inserted into the inner wall of the gear ring 25. The contact block 28 is fixed at one side of the sliding rod 27. The impact head 30 is fixed at the other side of the sliding rod 27. The spring 29 is sleeved on the outer circumferential surface of the sliding rod 27. One side of the protrusion 26 and the contact block 28 are arc-shaped. The side of the impact head 30 away from the adjacent contact block 28 is arc-shaped. One side of the spring 29 is fixed to the surface of the adjacent contact block 28. The other side of the spring 29 is fixed to the inner wall of the gear ring 25. When the two sets of clamps 15 and gear ring 25 are assembled into a complete ring structure to enclose the pipe to be processed, and rotate under the meshing action with gear 24, they can drive the protrusion 26 to make a circular motion. This allows the sliding rod 27 to move closer to the outer wall of the pipe under the contact action of the arc-shaped surface of the protrusion 26 and the contact block 28. This allows the impact head 30 to strike the outer wall of the pipe. During this process, the spring 29 can deform, and when the protrusion 26 moves away from the contact block 28, the sliding rod 27 can return to its original position under the rebound force of the spring 29. The vibration force generated by the impact head 30 can crack the dense old lining attached to the inside of the pipe wall. The old scale hard shell is loosened, and the adhesion between the scale and the metal pipe wall is broken, so that the scale layer has pores and the closed barrier of the scale is broken. When the electric trolley 1 drives the electromagnetic coil 8 to move to the outer wall of the pipe after being knocked, the electromagnetic field can efficiently penetrate the loose scale layer and act on the inside of the scale and the interface of the pipe wall. Thus, the pre-vibration pretreatment can effectively eliminate the blocking effect of hard scale on the magnetic field, improve the utilization rate of electromagnetic energy and the treatment depth, and reduce the power consumption of the device. Since the surface of the impact head 30 near the pipe is arc-shaped, the impact force can be evenly distributed during the knocking process. Only the vibration impact force is transmitted, and no scratching or cutting stress is generated, so the outer wall of the pipe will not be scratched.

[0028] The pretreatment assembly also includes an annular opening 31, a fixing rod 32, a vibration motor 39, and an arc-shaped contact plate 40. The annular opening 31 is located on the inner wall of the gear ring 25 at the middle position of the two sliding rods 27. The fixing rod 32 is fixed to the inner circumferential surface of the gear ring 25 near the annular opening 31. The fixing rod 32 and the annular opening 31 are slidably inserted and connected. The vibration motor 39 is fixed to one end of the fixing rod 32. The arc-shaped contact plate 40 is fixed to the surface of one side of the vibration motor 39. The vibration motor 39 and the battery 3 are electrically connected. Before pre-treatment of the pipe after long-term use by hammering, when the gear ring 25 rotates, the fixing rod 32 can move in a circle with the gear ring 25, so that the vibration motor 39 and the arc-shaped contact plate 40 that is attached to the outer circumference of the pipe can move in a circle. After the vibration motor 39 is started, it generates a micro-vibration, which is transmitted to the pipe through the arc-shaped contact plate 40. Due to the movement trajectory of the fixing rod 32, the micro-vibration can be evenly applied to the position where the arc-shaped contact plate 40 contacts the pipe. The micro-vibration transmitted by the arc-shaped contact plate 40 can reduce the adhesion of scale on the inner wall of the pipe after long-term use and destroy the bonding force of the scale base, providing good conditions for the subsequent hammering and peeling of the scale by the impact head 30, and improving the efficiency of scale removal.

[0029] The inner wall of the gear ring 2 33 is connected to a detection component, which includes an infrared thermal imaging temperature probe 34, a heating plate 35, a gear ring 36, a brush rod 37, and a gear 2 38. The infrared thermal imaging temperature probe 34 is fixed at the inner circumferential surface of one of the gear rings 2 33. The heating plate 35 is fixed at both ends of the infrared thermal imaging temperature probe 34 on the inner circumferential surface of the gear ring 2 33. The gear ring 36 is fixed at the inner side of the two clamps 2 15. The brush rod 37 is rotatably connected to the inner circumferential surface of the other gear ring 2 33. The gear 2 38 is fixedly sleeved on the outer circumferential surface of the brush rod 37. The gear 2 38 and the gear ring 36 are meshed together. The infrared thermal imaging temperature probe 34 is electrically connected to the heating plate 35 and the battery 3. When the electric trolley 1 moves to the rear, the pipe surface, which has undergone pretreatment by the impact head 30 and electromagnetic descaling by the electromagnetic coil 8, is wrapped by the gear ring 33. The impact head 30 and the electromagnetic coil 8 perform pretreatment and electromagnetic descaling on the pipe surface at the rear. By pre-activating the heating plate 35, the heating plate 35 can heat the pipe surface at the contact point. The heating plate 35 can also make circular motions along the rotation trajectory of the gear ring 33, achieving uniform heating of the circumference of the adjacent area of ​​the pipe, making the pipe evenly heated. Then, the temperature of the inner and outer walls of the pipe is observed by the infrared thermal imaging temperature probe 34. Since scale has heat insulation properties, if the temperature difference between the outer and inner walls of the pipe is large as observed by the infrared thermal imaging temperature probe 34, scale residue will still remain on the inner wall of the pipe after treatment. It is necessary to move the electric trolley 1 back to perform secondary treatment on the local area of ​​the pipe with a large temperature difference between the inner and outer walls. During descaling, if the infrared thermal imaging temperature probe 34 observes that the temperatures of the outer and inner walls of the pipe are similar, then the scale adhering to the inner wall of the pipe is cleaned. When the gear ring 33 rotates due to the meshing action of the gear 24, it can drive the brush rod 37 and the gear 38 to make circular motion. Thus, under the meshing action of the gear ring 36 and the gear 38, the brush rod 37 rotates, allowing one side of the brush rod 37 to adhere to the outer wall of the pipe while making circular motion and rotating motion. Under the friction between the brush rod 37 and the outer wall of the pipe, iron filings, dust, and other impurities adhering to a certain circumferential range on the outer wall of the pipe are cleaned by the brush rod 37. This further ensures that the heating plate 35 heats the pipe evenly and fully, so that the infrared thermal imaging temperature probe 34 can clearly observe the temperature of the inner and outer walls of the pipe, thereby improving the detection accuracy and making the user's judgment on whether there is scale adhering to the inner wall of the pipe more accurate.

[0030] Example 3, Third aspect, Second aspect, as Figures 1-9 The present invention provides a high-frequency electromagnetic scale inhibition method for wastewater treatment, comprising the following steps: Step 1: Check the integrity of each component of the device, ensure that the battery 3 has sufficient power, the power-consuming part is in normal standby state, and that the fiberglass insulating tape 13, bolts and fasteners 9 and other accessories are complete. Control the electric trolley 1 to move to the bottom of the pipe that needs to be descaled, adjust the position of the electric trolley 1 to ensure that the mounting base 4 and the components above it are aligned directly below the pipe, so that the clamp 7 can wrap the pipe later.

[0031] Step 2: Start hydraulic cylinder 5, so that the output end of hydraulic cylinder 5 drives the mounting base 4 to rise vertically until the electromagnetic descaling component at the top of the mounting base 4 moves to a height that can cover the outer circumference of the pipe. Then, turn off hydraulic cylinder 5 and lock the position.

[0032] Step 3: Insert the male circuit connector 10 at one end of the top of the electromagnetic coil 8 into the female circuit connector 11 at the other end, so that the magnetic conductive contacts 12 of the two are in contact with each other, and splice the electromagnetic coil 8 into a complete ring. At the splicing point of the male circuit connector 10 and the female circuit connector 11, glue the fiberglass insulating tape 13 to ensure that the high-frequency magnetic flux circuit is complete and there is no magnetic field leakage.

[0033] Step 4: Start motor 18 to make the two bidirectional threaded rods 17 rotate synchronously, so that clamp 14 and clamp 25 move closer to each other until the two sets of clamp 14 are in contact with the gear ring 25 and the two sets of clamp 25 are in contact with the gear ring 33, forming a complete ring and wrapping the pipe.

[0034] Step 5: Start the vibration motor 39 and motor 22, so that the vibration motor 39 and the arc-shaped contact plate 40 are in contact with the outer circumference of the pipe and make circular motion. The slight vibration generated by the vibration motor 39 is transmitted to the pipe through the arc-shaped contact plate 40, which loosens the base binding force of the scale on the inner wall of the pipe. The pretreatment time is adjusted according to the thickness of the scale layer in the pipe. The protrusion 26 abuts against the contact block 28 through the arc surface, so that the impact head 30 repeatedly knocks on the outer wall of the pipe, preparing for the subsequent electromagnetic descaling.

[0035] Step Six: Start the electromagnetic descaling main control unit 2, control the electromagnetic coil 8 to generate an alternating electromagnetic field, control the electric trolley 1 to slide along the outer circumference of the pipeline, drive the electromagnetic descaling components to move synchronously, and gradually expand the range of the high-frequency alternating electromagnetic field and the pretreatment range of the pipeline.

[0036] Step 7: Pre-start the heating plate 35. The heating plate 35 rotates with the gear ring 2 33 to make a circular motion, which heats the outer circumference of the pipe evenly. The temperature of the inner and outer walls of the pipe is observed by the infrared thermal imaging temperature measuring probe 34. During the heating of the pipe, the brush rod 37 is used to clean the iron filings, dust and other impurities on the outer wall of the pipe to ensure uniform heating in the future.

[0037] Step 8: After the designated area of ​​the pipeline has been completely treated and passed the inspection, turn off all electrical equipment, loosen the bolts and fasteners 9, open the clamps 7, start the hydraulic cylinder 5 to lower the mounting base 4 and the electromagnetic descaling component to the initial position, control the electric trolley 1 to move to the next section of the pipeline to be treated, repeat the above operation, or move to the designated storage location to complete the operation.
