DETAILED DESCRIPTION

[0025] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0027] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] The following combination Figures 1-6 The pipeline anti-scaling device 10 according to an embodiment of the present invention will be described in detail.

[0029] Reference Figure 1As shown, the pipeline anti-scaling device 10 includes: a magnetic conductive component 1, a plurality of coils 2 and a signal generator 3. The magnetic conductive component 1 is suitable for being set on the outside of the pipeline. The magnetic conductive component 1 passes through each coil 2, and the plurality of coils 2 are arranged at intervals. The signal generator 3 is electrically connected to at least one coil 2. The signal generator 3 can provide a preset frequency, waveform and output level electrical signal to the coil 2 electrically connected thereto. The signal generator 3 can be a high-frequency signal generator, and an LC oscillator is used as the main oscillator. When the signal generator 3 is working, the signal generator 3 can transmit an electrical signal of a preset frequency to the coil 2 electrically connected thereto to form an L In the loop of the C oscillation circuit, the coil 2 generates a high-frequency alternating current. According to the magnetic effect of the current, the coil 2 generates an alternating electromagnetic field. The magnetic conductive component 1 can conduct magnetism to form a ring-shaped alternating electromagnetic field and act on the solution in the pipeline. Under the action of the alternating electromagnetic field, the molecular lattice of the sediment in the solution is destroyed, forming new crystal nuclei, and then re-arranged and kept in a suspended state to avoid the formation of sediment crystallization on the inner wall of the pipeline and prevent the formation of scale. At the same time, a dynamic balance is formed between the crystallization and the supersaturated solution, and the process of crystallization and scale dissolution is continuously carried out. Its change process can be expressed as follows using calcium carbonate as an example: That is to say, under the action of the alternating electromagnetic field, the calcium carbonate solids that scale in the pipeline can be reduced while forming new crystals, thereby reducing the formation of scale in the pipeline and removing the scale deposited in the pipeline to avoid the pipeline being attached by scale, preventing the inner diameter of the pipeline from becoming smaller and the pipeline from being blocked.

[0030] It should be noted that, at a given frequency, when the inductance parameters and capacitance are constant, multiple coils 2 can be electrically connected to the signal generator 3 after being connected in series or in parallel. When the given inductance parameters are the same, the same power consumption of multiple coils 2 and a single coil 2 can be achieved. Since the magnetic conductive component 1 will have energy loss during the magnetic conductive process, the longer the magnetic conductive component 1 is (the larger the magnetic core ring 11 structure), the greater the energy loss, which results in a stronger electromagnetic field strength of the magnetic ring close to the coil 2 and a weaker magnetic ring far from the coil 2. The magnetic conductive component 1 can be an annular magnetic core structure. The multiple coils 2 arranged at intervals can make the electromagnetic field of the annular magnetic conductive component 1 uniformly distributed without increasing the power consumption of the signal generator 3. The alternating electromagnetic field of the annular magnetic conductive component 1 is uniformly distributed in the pipeline through the principle of electromagnetic induction while increasing the electromagnetic field strength inside the pipeline to ensure the anti-scaling effect on large-diameter pipelines. At the same time, the multiple coils 2 are connected to the same signal generator 3 to ensure that each coil 2 operates at the same frequency and phase to reduce power loss and enhance the electromagnetic field strength in the pipeline.

[0031] According to the pipeline anti-scaling device 10 of an embodiment of the present invention, the magnetic conductive component 1 is provided with multiple spaced-apart coils 2 and is sleeved on the outside of the pipeline. The signal generator 3 is electrically connected to at least one coil 2. A uniform electromagnetic field with a certain intensity is formed in the pipeline through the principle of electromagnetic induction. The electromagnetic field acts on the liquid in the pipeline to reduce the formation of scale in the pipeline and remove the scale deposited in the pipeline, thereby realizing the pipeline anti-scaling function.

[0032] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the signal generator 3 is electrically connected to the multiple group coils 2, and the multiple group coils 2 electrically connected to the signal generator 3 are connected in forward parallel. It can be understood that each group coil 2 has a coil 23 wound in the same direction, and the starting end 231 of each coil 23 is connected to the signal generator 3, and the ending end 232 of each coil 23 is connected to the signal generator 3. The multiple group coils 2 connected in forward parallel can form a same-direction coupling. The same-name ends of the multiple group coils 2 connected in forward parallel are current inflow ends. The original current generates the same magnetic flux direction on the mutually inducted group coils 2, which plays an enhancing role, so as to effectively enhance the strength of the electromagnetic field in the pipeline.

[0033] In other embodiments of the present invention, referring to Figure 1 and Figure 2 As shown, the signal generator 3 is electrically connected to the multiple coil groups 2, and the multiple coil groups 2 electrically connected to the signal generator 3 are connected in series in a forward direction. It can be understood that each coil group 2 has a coil 23 wound in the same direction, and in the current direction, the terminal end 232 of the previous coil 23 is connected to the starting end 231 of the next coil 23. The multiple coil groups 2 connected in series in a forward direction can form a same-direction coupling. The same-named ends of the multiple coil groups 2 connected in series in a forward direction are current inflow ends. The original current generates the same direction of magnetic flux on the mutually inductive coil groups 2, which plays an enhancing role, thereby effectively enhancing the strength of the electromagnetic field in the pipeline.

[0034] In some embodiments of the present invention, reference Figure 1 and Figure 2 As shown, the pipeline anti-scaling device 10 includes a first set of coils 201 and a second set of coils 202. The self-inductance coefficient of the first set of coils 201 is L1, and the current passing through the first set of coils 201 is i1. The self-inductance coefficient of the second set of coils 202 is L2, and the current passing through the second set of coils 202 is i2. The magnetic flux linkage is represented by Ψ. When the signal generator 3 is only connected to the first set of coils 201 or the second set of coils 202, the magnetic flux linkage generated by the first set of coils 201 is Ψ11=L1*i1, and the magnetic flux linkage generated by the second set of coils 202 is Ψ22=L2*i2.

[0035] When the first group of coils 201 and the second group of coils 202 are connected in forward parallel or forward series and are simultaneously connected to the signal generator 3, the magnetic flux linkage Ψ1 generated by the first group of coils 201 is equal to the self-magnetic linkage plus the mutual magnetic linkage, that is, Ψ1=Ψ11+Ψ12=L1*i1+M12*i2, and the magnetic flux linkage Ψ2 generated by the second group of coils 202 is equal to the self-magnetic linkage plus the mutual magnetic linkage, that is, Ψ2=Ψ22+Ψ21=L2*i2+M21*i1, where Ψ12 is the mutual magnetic linkage generated by the second group of coils 202 on the first group of coils 201, Ψ21 is the mutual magnetic linkage generated by the first group of coils 201 on the second group of coils 202, M12 and M21 are mutual inductance coefficients, and M12=M21.

[0036] k=M / √L1*L2=√M 2 / L1*L2=√M*i1*M*i2 / L1*i1*L2*i2=√Ψ12*Ψ21 / Ψ11*Ψ22≤1, k is the coupling coefficient, M is the mutual inductance coefficient. It can be seen from the formula that the self-magnetic linkage must be greater than the mutual magnetic linkage. When k=1, it is a full coupling phenomenon, and when k=0, there is no coupling.

[0037] The first set of coils 201 and the second set of coils 202 are coupled inductors. Regarding the voltage and current on the coupled inductors, due to the alternating electromagnetic field required by the pipeline anti-scaling device 10, the current flowing through the first set of coils 201 and the second set of coils 202 is a function that changes with time, called a time-varying current. Therefore, the first set of coils 201 and the second set of coils 202 will generate an induced voltage. Due to the coupling effect, the induced voltage consists of two parts: self-inductance voltage and mutual inductance voltage, where:

[0038] The self-inductance voltage U11 of the first coil group 201 is dΨ11 / dt=L1*di1 / dt, the self-inductance voltage U22 of the second coil group 202 is dΨ22 / dt=L2*di2 / dt, the mutual inductance voltage U12 of the first coil group 201 is dΨ12 / dt=M12*di2 / dt, and the mutual inductance voltage U21 of the second coil group 202 is dΨ21 / dt=M21*di1 / dt. Therefore, the voltage U1 generated across the first coil group 201 is U11+U12, and the voltage U2 generated across the second coil group 202 is U22+U21.

[0039] When the pipeline anti-scaling device 10 is used for a large-diameter pipeline, in order to ensure that the electromagnetic field signal in the pipeline is evenly distributed and to improve the electromagnetic field strength, that is, to increase the values ​​of Ψ1, Ψ2, U1, and U2, it is only necessary to ensure that the mutual inductance magnetic flux linkage and the self-inductance magnetic flux linkage are in the same direction, so that the magnetic field can be strengthened, which belongs to the same-direction coupling. In this state, the inflow ends where the two currents flow in are called the same-name ends, and the electric field and the magnetic field can enhance each other.

[0040] Reference Figure 1 and Figure 2As shown, ensuring that the first and second coil groups 201 and 202 have the same terminals effectively enhances the electromagnetic field. Furthermore, the electromagnetic fields generated by the two coil groups 2 have consistent frequencies and phases, effectively resolving the problem of superposition and cancellation caused by inconsistent frequencies and phases of LC signals generated by multi-channel signal generators 3 in some prior art techniques. Furthermore, multi-channel LC systems consume high power and waste energy. The pipeline anti-scaling device 10 according to an embodiment of the present invention can effectively resolve the uneven distribution of the electromagnetic field generated by the pipeline anti-scaling device 10 when used on large-diameter pipelines. It can also effectively increase the strength of the electromagnetic field, thereby enhancing the water treatment effect on large-diameter pipelines.

[0041] In addition, the LC resonant frequency calculation formula is: F = 1 / (2*π*√LC). The calculation formula for multiple groups of coils 2 in series and in parallel is the same, where L represents inductance, unit: Henry (H), C represents capacitance, unit: Farad (F), and the LC oscillation circuit of the signal generator 3 includes an H-bridge, a capacitor, and an inductor. When the H-bridge frequency is constant, the output power is determined by the capacitance and inductance values ​​in the circuit. The capacitance is generally fixed in the circuit, and the only factor affecting the resonant frequency is the inductance value of the coil 23 in the circuit. As long as the inductance value is fixed, the output power of the circuit is constant. Therefore, no matter how many groups of coils 2 are connected to the circuit, as long as the inductance value after parallel or series connection remains unchanged, the output power remains unchanged, thereby reducing the energy consumption of the pipeline anti-scaling device 10 and ensuring that the electromagnetic field strength of the annular magnetic conductive component 1 is evenly distributed.

[0042] It should be noted that, among the multiple groups of coils 2, some of the group coils 2 can be connected to the signal generator 3 in series or in parallel, and the other group coils 2 can be not connected to the signal generator 3. The group coils 2 not connected to the signal generator 3 are non-closed windings, and their coils 23 are not closed, and no closed loop is formed. There is no current in the coils 23. According to the principle of electromagnetic induction, an alternating electromotive force will be induced. The magnitude of the induced electromotive force is proportional to the number of turns of the coil 23. According to Faraday's electromagnetic induction principle, the alternating electric field will induce an induced magnetic field. The stronger the electromagnetic field generated by the coils 23 connected to the signal generator 3, the stronger the electric field of the coils 23 not connected to the signal generator 3. Therefore, the electromagnetic field strength and distribution uniformity in the pipeline can be further improved.

[0043] As some feasible embodiments, the pipeline anti-scaling device 10 may include four groups of coils 2, which are respectively a first group of coils, a second group of coils, a third group of coils, and a fourth group of coils. The electrical connection relationship in the pipeline anti-scaling device 10 includes at least the following schemes:

[0044] Solution 1: One or more of the first, second, third and fourth coils are connected in series or in parallel to the signal generator 3 , while the others are not connected and are set separately.

[0045] Solution 2: The first group of coils is connected to the signal generator 3, and the second, third and fourth groups of coils are not connected to the signal generator 3, but the second, third and fourth groups of coils are connected in series or in parallel.

[0046] Solution 3: The first and second coils are connected in series or in parallel to form one group, and the third and fourth coils are connected in series or in parallel to form another group. Then, the two groups are connected in series or in parallel to the signal generator 3 .

[0047] Among them, the series connection is forward series connection, and the parallel connection is uniform forward parallel connection to improve the uniformity of the electromagnetic field intensity and distribution in the pipeline.

[0048] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the magnetic conductive component 1 is constructed in an annular shape. The annular magnetic conductive component 1 is suitable for being sleeved on the outer wall of the pipeline. A plurality of coils 2 are arranged at intervals along the circumferential direction of the magnetic conductive component 1 so that the electromagnetic field at each position in the pipeline can be evenly distributed. According to the principle of electromagnetic induction, the electromagnetic field in the pipeline can be evenly distributed and the electromagnetic field strength in the pipeline can be effectively improved, thereby preventing the formation of solid scale inside the pipeline and adsorbing on the inner wall of the pipeline.

[0049] Preferably, multiple group coils 2 are arranged at equal intervals along the circumferential direction of the magnetic conductive component 1. When the number of group coils 2 is n (n≥2 and is an integer), the angle formed by any two adjacent group coils 2 and the center of the magnetic conductive component 1 is 360° / n. For example, when the number of group coils 2 is 2, the angle formed by the two group coils 2 and the center of the magnetic conductive component 1 is 180°. When the number of group coils 2 is 3, the angle formed by any two adjacent group coils 2 and the center of the magnetic conductive component 1 is 120°.

[0050] Of course, the distances between the multiple coil groups 2 along the circumferential direction of the magnetic conductive component 1 may also be different, and the distances between the multiple coil groups 2 may be adjusted according to on-site conditions such as the installation environment and the shape of the pipeline.

[0051] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the magnetic conductive component 1 includes a magnetic core ring 11, which includes multiple magnetic cores 111 connected end to end in sequence. The magnetic cores 111 can be ferrite, and any two adjacent magnetic cores 111 can be rotatably and / or detachably connected to enable the magnetic core ring 11 to better fit the outer wall of the pipe.

[0052] In some embodiments, any two adjacent magnetic cores 111 can be rotatably connected, and adjacent magnetic cores 111 can be connected by a rotating shaft. When the pipeline is a circular pipeline, the magnetic core 111 can be rotated to form an approximately circular ring structure to be mounted on the outer wall of the pipeline. When the pipeline is a rectangular pipeline, the magnetic core 111 can be rotated to form a rectangular ring structure to be mounted on the outer wall of the pipeline.

[0053] In other embodiments, any two adjacent magnetic cores 111 can be detachably connected, and adjacent magnetic cores 111 can be connected by pins. The number of magnetic cores 111 can be increased or decreased to make the magnetic core ring 11 suitable for fitting on the outer wall of pipes with different diameters, and the magnetic core ring 11 can be directly assembled on the outside of the pipe so that the assembled magnetic core ring 11 can be mounted on the outside of the pipe, which is beneficial to the installation and debugging of the pipeline anti-scaling device 10.

[0054] In some other embodiments, referring to Figure 3 As shown, any two adjacent magnetic cores 111 can be rotatably and detachably connected, and the adjacent magnetic cores 111 can be connected by a fastener 112. The fastener 112 includes a bolt 1121 and a nut 1122. Connecting holes can be provided at both ends of the magnetic core 111. The rod of the bolt 1121 can pass through the connecting holes of the two adjacent magnetic cores 111 and then cooperate with the nut 1122. The diameter of the rod of the bolt 1121 is smaller than the diameter of the connecting hole, so that the two magnetic cores 111 connected by the bolt 1121 and the nut 1122 can be rotatable. By removing the bolt 1121 and the nut 1122, the number of magnetic cores 111 in the magnetic core ring 11 can be increased or decreased to adapt to pipes of all diameters and facilitate the installation and commissioning of the pipeline anti-scaling device 10.

[0055] In some embodiments of the present invention, reference Figure 1-Figure 3 As shown, the magnetic conductive component 1 includes a plurality of magnetic core rings 11, and the plurality of magnetic core rings 11 are coaxially spaced apart, and the spacing distance between two adjacent magnetic core rings 11 can be 0.5 cm to 5 cm. That is to say, after the magnetic conductive component 1 is assembled, the plurality of magnetic core rings 11 are spaced apart along the length direction of the pipeline, so that the electromagnetic field can affect the solution within a certain length of the pipeline, thereby increasing the action time of the electromagnetic field on the solution in the pipeline, so that the molecular motion state of the solution after the electromagnetic field is acted upon will be maintained for a period of time, thereby ensuring that the solution within a certain length range (such as 2 km) downstream of the anti-scaling device will not produce scale precipitation, thereby improving the anti-scaling effect of the pipeline anti-scaling device 10.

[0056] In some embodiments of the present invention, reference Figure 4-Figure 6As shown, the coil assembly 2 includes an outer shell 21, an inner frame 22, and a coil 23. The coil 23 is wound around the inner frame 22, and the outer shell 21 is covered on the outside of the coil 23 and the inner frame 22. The outer shell 21 and the inner frame 22 can both be made of insulating plastic. The inner frame 22 can fix and support the coil 23, and the outer shell 21 is used to protect the inner frame 22 and the coil 23. In addition, the magnetic conductive component 1 can be penetrated by the inner frame 22 and the outer shell 21. When the magnetic conductive component 1 includes a plurality of magnetic core rings 11, the outer shell 21 is provided with first positioning holes 2115 corresponding to the number of magnetic core rings 11, and the inner frame 22 is provided with second positioning holes 222 corresponding to the number of magnetic core rings 11. The magnetic core rings 11 can be penetrated by the first positioning holes 2115 and the second positioning holes 222. The inner frame 22 and the outer shell 21 can evenly space the plurality of magnetic core rings 11. When multiple coil groups 2 are connected in series in the forward direction, the winding direction of the coils 23 of each coil group 2 is consistent, and in the current direction, the terminating end 232 of the previous coil 23 is connected to the starting end 231 of the next coil 23. When multiple coil groups 2 are connected in parallel in the forward direction, the winding direction of the coils 23 of each coil group 2 is consistent, and the starting end 231 of each coil 23 is connected, and the terminating end 232 of each coil 23 is connected.

[0057] In some embodiments of the present invention, reference Figure 4 As shown, the shell 21 includes a main body portion 211 and an end cover portion 212 that are detachably connected. The main body portion 211 and the end cover portion 212 jointly define an installation space. The inner skeleton 22 and the coil 23 are both arranged in the installation space, and the main body portion 211 and the end cover portion 212 are suitable for limiting cooperation with the inner skeleton 22 to ensure the stability of the connection between the inner skeleton 22 and the shell 21 and prevent the inner skeleton 22 from shaking in the shell 21. When assembling the coil 2, the end cover portion 212 can be removed from the main body portion 211, and then the inner skeleton 22 with the coil 23 wound thereon can be placed in the main body portion 211, and then the end cover portion 212 can be installed back on the main body portion 211 to fix the inner skeleton 22 in the shell 21.

[0058] Reference Figure 4 and Figure 6 As shown, the main body 211 has one or more limiting grooves 2111, and the inner skeleton 22 has a guide block 221 suitable for correspondingly cooperating with the limiting groove 2111. The inner skeleton 22 can be installed into the main body 211 along the limiting groove 2111 through the guide block 221. After the end cover 212 is connected to the main body 211, the end cover 212 can stop the guide block 221 in the extension direction of the limiting groove 2111 to realize the full-directional limitation of the inner skeleton 22 by the outer shell 21.

[0059] In some embodiments of the present invention, reference Figure 5As shown, the end cover portion 212 includes a first sub-end cover 2121 and a second sub-end cover 2122, the first sub-end cover 2121 is suitable for covering one end of the main body portion 211, and the second sub-end cover 2122 is suitable for covering the other end of the main body portion 211, and the main body portion 211 includes one or more sub-main body portions 2112, one end of each sub-main body portion 2112 is provided with a first plug pin 2113, and the other end is provided with a first plug hole 2114, and the first plug pin 2113 is suitable for plugging and cooperating with the first plug hole 2114, and each sub-main body portion 2112 is provided with a first positioning hole 2115 suitable for a magnetic core ring 11 to pass through. When assembling the pipeline anti-scaling device 10, a corresponding number of sub-main body portions 2112 can be selected according to the number of magnetic core rings 11 of the magnetic conductive component 1, and the corresponding number of sub-main body portions 2112 are connected in sequence through the first plug pin 2113 and the first plug hole 2114.

[0060] In some embodiments of the present invention, the inner skeleton 22 may include one or more sub-inner skeletons, each sub-inner skeleton is provided with a second plug pin at one end and a second plug hole at the other end, and the second plug pin is suitable for plugging into the second plug hole, and each sub-inner skeleton is provided with a second positioning hole 222 suitable for a magnetic core ring 11 to pass through. When assembling the pipeline anti-scaling device 10, a corresponding number of sub-inner skeletons can be selected according to the number of magnetic core rings 11 of the magnetic conductive component 1, and the corresponding number of sub-inner skeletons can be connected in sequence through the second plug pin and the second plug hole.

[0061] In some embodiments of the present invention, the coil assembly 2 further includes insulating glue, which fills the gaps between the outer shell 21, the inner skeleton 22, and the coil 23. The insulating glue may be epoxy resin. The coil assembly 2 is processed by glue filling to improve the connection strength between the outer shell 21 and the inner skeleton 22. The insulating glue may also cover the coil 23 to isolate the coil 23 from the external environment, thereby preventing the coil 23 from rusting when working in an environment with high humidity. When the pipeline anti-scaling device 10 works in a harsh environment, the reliability and service life of the coil assembly 2 can be ensured.

[0062] In some embodiments of the present invention, reference Figure 1 As shown, the signal generator 3 is fixedly connected to the outer shell 21 of one of the plurality of coil groups 2.
