[0002] In practical applications, industrial wastewater discharges are subject to a series of restrictions. Industrial wastewater must be treated before it can be discharged. Industrial wastewater or treated industrial wastewater contains impurities that easily remain in liquid pipes and solidify on the liquid pipe walls. Related technologies typically utilize a multi-row magnetic core multi-head arrangement in large pipes to remove impurities from the liquid pipe walls through pulse vibration. Because the frequencies or phases of multiple LC oscillator circuits vary, the different waveforms superimpose and cancel each other, weakening the output electromagnetic field strength and thus affecting the descaling effect.

[0028] 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.

[0029] Before describing the embodiments of the present invention in detail, a brief introduction to related technologies is first given.

[0030] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a liquid pipe descaling device in the related art. Figure 1 It includes a signal generator, three rows of magnetic core components, three sets of coils and three sets of capacitors, wherein the three sets of coils and three sets of capacitors form three LC oscillation circuits respectively. Figure 1 In the liquid pipe descaling device, multiple rows of magnetic cores are used. The three-way LC oscillation circuit in the liquid pipe descaling device is conducive to the uniform distribution of the pulse signal in the pipe diameter, and can increase the electromagnetic field strength, thereby improving the descaling effect.

[0031] Specifically, f1, f2, and f3 are the resonant frequencies of the three-way LC oscillation circuit, and the inductance parameters of the three sets of coils are L1, L2, and L3 respectively. According to the resonant frequency calculation formula Among them, L is the inductance parameter of the coil, and C is the capacitance value of the capacitor. It can be seen that the resonant frequency is affected by the inductance parameter and the capacitance value. Among them, the capacitance value itself has an error range, and the capacitance value of each capacitor may have deviations. The inductance parameter is affected by the winding process of the coil, and the consistency of the inductance parameter is poor, that is, the inductance parameters L1, L2 and L3 of the coil may all be different, which leads to different resonant frequencies f1, f2 and f3 of the three-way LC oscillation circuit.

[0032] According to the principle of waveform superposition, if several waves propagate simultaneously in a medium, they propagate independently with their own original characteristics (including amplitude, frequency, wavelength, vibration direction, and propagation direction). In the area where the waves meet, the displacement of the particle is equal to the vector sum of the displacements caused by each wave propagating alone. Figure 2-Figure 5 The superposition scenario shown, where Figure 2 This is a schematic diagram of the superposition of two waves with the same frequency but different amplitudes. Figure 3 This is a schematic diagram of the superposition of two waveforms with different frequencies and the same amplitude. Figure 4 This is a schematic diagram of the superposition of two waveforms with similar frequencies. Figure 5 This is another schematic diagram of the superposition of two waves with similar frequencies.

[0033] This shows that in the liquid pipe descaling device of the related art, the output waveform has the effect of superposition, which enhances or cancels out the effect, resulting in unstable output electromagnetic field strength. To ensure the enhanced waveform superposition effect, it is necessary to ensure that the resonant frequencies of f1, f2, and f3 are the same and the phases are consistent. However, in the liquid pipe descaling device of the related art, the resonant frequencies of the three LC oscillating circuits are inconsistent, affecting the output of the electromagnetic field and thus the descaling effect.

[0034] Based on this, a new liquid pipe descaling device is proposed in this application, which can stably output a strong electromagnetic field, which is conducive to improving the descaling effect.

[0035] The following describes in detail the implementation details of the technical solutions of the embodiments of the present application.

[0036] In one embodiment, Figure 6 As shown, a liquid pipe descaling device is provided. The liquid pipe descaling device 10 includes a magnetic core component 11, a resonant coil 12 and a resonant capacitor 13.

[0037] Reference Figure 6 and Figure 7 As shown, the magnetic core assembly 11 includes multiple magnetic cores 111. In one implementation, the magnetic core assembly 11 contains three magnetic cores 111. Compared with a single magnetic core, multiple magnetic cores can make the magnetic core assembly 11 have a stronger magnetic permeability and a smaller loss rate during energy conduction, which is beneficial to improving the electromagnetic field strength output by the magnetic core assembly 11. The magnetic core assemblies 11 are arranged side by side along the axial direction, see Figure 6 As shown, the center of the magnetic core assembly 11 is an insertion hole, through which the magnetic core assembly 11 is mounted on the liquid pipe. In practical applications, there is no limitation on the liquid pipe, and the liquid pipe can be a petrochemical pipeline or a water pipe. The following description uses the liquid pipe as a water pipe.

[0038] The resonant coil 12 is wound on the magnetic core component 11. The resonant coil 12 and the resonant capacitor 13 together form an LC oscillation circuit, wherein the resonant capacitor 13 has the characteristics of charging and discharging, and the resonant coil 12 has the characteristics of hindering current changes, which can realize the mutual conversion of electric field and magnetic field. The resonant coil 12 and the resonant capacitor 13 are combined together to store the resonant energy when the circuit resonates. Specifically, when the resonant capacitor 13 discharges to generate current, the resonant inductor 12 will hinder the current from passing through, converting the electric field into a magnetic field, and then storing the energy; when the resonant capacitor 13 finishes discharging, the resonant inductor 12 will hinder the disappearance of the current, and the magnetic field in the resonant inductor 12 is converted into an electric field. The generated current is used to charge the resonant capacitor 13; when charging is completed, the resonant capacitor 13 starts to discharge in the opposite direction, thereby forming oscillation energy. In this embodiment, when the LC oscillation circuit is working, it is configured to use pulse vibration to descale the water pipe.

[0039] In actual applications, the resonant capacitor 13 can be connected to a signal generator, which can output a pulse signal, so that the LC oscillation circuit can work. When the LC oscillation circuit is working, the resonant coil 12 can generate an alternating current. When the alternating current flows through the magnetic core component 11, it generates an alternating electromagnetic field. The output alternating electromagnetic field acts on the medium in the water pipe, thereby realizing the function of descaling the water pipe.

[0040] In this embodiment, a one-way LC oscillation circuit is used, and the water pipe is descaled by adopting a pulse vibration method under the operation of the LC oscillation circuit. Therefore, the power consumption of the liquid pipe descaling device 10 is approximately the power consumption of a one-way LC oscillation circuit. Compared with the solution of adopting multiple LC oscillation circuits (in the solution of n>1 LC oscillation circuits, the power consumption is n*P), the power consumption required for descaling can be reduced, and the strength of the output electromagnetic field can also be guaranteed.

[0041] In one embodiment, reference Figure 8 As shown, Figure 8 The schematic diagram of the structure of an LC oscillating circuit is shown. The LC oscillating circuit further includes an H-bridge unit 14. The H-bridge unit 14 is connected to the resonant capacitor 13. The resonant capacitor 13 is further connected to the resonant coil 12. The H-bridge unit 14, the resonant capacitor 13 and the resonant coil 12 form an LC oscillating circuit. Specifically, Figure 8 In the H-bridge unit 14, four field effect tubes (Q1, Q2, Q3 and Q4) are included. Q1 and Q2 form the first bridge arm, and Q3 and Q4 form the second bridge arm. Figure 8, includes two resonant capacitors 13. To distinguish these two resonant capacitors 13, they are labeled C1 and C2, respectively. The first bridge arm is connected to C1, and the second bridge arm is connected to C2. C1 and C2 are then connected to the resonant coil 12. This connection method can effectively filter out the reverse interference generated by the resonant coil 12. In one implementation, the two ends of the resonant coil 12 are respectively designated as a first terminal 1 and a second terminal 2. A third terminal 3 is also extended between the first terminal 1 and the second terminal 2. The first terminal 1 is connected to C1, and the third terminal 3 is connected to C2.

[0042] When the resonant circuit is working, the controller controls the conduction and cutoff of Q1, Q2, Q3 and Q4 in the H-bridge unit 14 through high and low levels, so that the H-bridge unit 14 can output a square wave signal, and the resonant capacitor 13 and the resonant coil 12 can convert the square wave signal into a sine wave signal. When the sine wave signal acts on the water pipe, it can generate pulse vibrations on the dirt inside the water pipe, thereby realizing the descaling function.

[0043] In one embodiment, reference Figure 7 As shown, Figure 7 A schematic diagram of the structure of a magnetic core is shown. A magnetic core 111 includes multiple magnets 1111, and the multiple magnets 1111 are connected in a ring shape, that is, the magnetic core 111 is ring-shaped. Figure 7 In the figure, a magnetic core 111 includes ten magnets 1111. In practical applications, the number of magnets 1111 included in a magnetic core 111 can be set according to actual needs. Generally, the more magnets 1111 there are, the stronger the output electromagnetic field. It is understood that multiple magnets 1111 connected in a ring form a magnetic core 111, and multiple ring-shaped magnetic cores 111 are combined to form a magnetic core assembly 11.

[0044] In one embodiment, each magnet 1111 in a magnetic core 111 is connected by bolts. Figure 7 As shown, each magnet 1111 is provided with a through hole, and a bolt is passed through the through hole to connect multiple magnets 1111.

[0045] In one embodiment, each magnet 1111 in a magnetic core 111 is provided with a through hole. When connecting each magnet 1111, the through holes of any two adjacent magnets 1111 are aligned, and a bolt can be placed in the aligned through hole, so that any two adjacent magnets 1111 can be connected with one bolt, wherein the aligned through hole is the connecting part of any two adjacent magnets 1111.

[0046] In one embodiment, at least one resonant capacitor 13 is configured, such as Figure 6 As shown, in Figure 6Two resonant capacitors 13 are configured. The number of resonant capacitors 13 can affect the capacitance value of the LC oscillator circuit, thereby affecting the resonant frequency of the LC oscillator circuit. The number and capacitance value of the resonant capacitors 13 can be configured according to the usage requirements. In actual applications, the resonant capacitors 13 can be connected in series with the resonant coil 12 to form an LC series resonant circuit. The resonant capacitors 13 can also be connected in parallel with the resonant coil 12 to form an LC parallel resonant circuit. Of course, the resonant capacitors 13 can also be connected in series and parallel with the resonant coil 12.

[0047] In one embodiment, the liquid pipe descaling device 10 includes an LC oscillation circuit. Since the inductance parameter of the resonant coil 12 and the capacitance parameter of the resonant capacitor 13 in the LC oscillation circuit remain unchanged, the resonant frequency It can be seen that one LC oscillation circuit has only one wave source, which can ensure that the resonant frequency and phase of multiple magnetic cores 111 remain the same. Therefore, the electromagnetic fields of multiple magnetic cores 111 can be resonated and superimposed to obtain a stronger electromagnetic field. The stronger electromagnetic field acts on the water pipe, which can achieve a better descaling effect.

[0048] In this embodiment, by adopting an LC oscillation circuit, the frequencies and phases of the multiple waveforms are ensured to be the same, which can ensure the stability of the output electromagnetic field strength and avoid the superposition and cancellation caused by the different frequencies and phases of the multiple waveforms to weaken the electromagnetic field strength.

[0049] It should be noted that the liquid pipe descaling device 10 can output electric fields and magnetic fields (that is, the electromagnetic fields mentioned above) when working, and in actual applications, different water pipe materials affect the electromagnetic field intensity output by the liquid pipe descaling device 10. Under normal circumstances, water pipe materials can be divided into plastic materials and metal materials. For plastic water pipes, without considering energy loss, the electric field and magnetic field output by the liquid pipe descaling device 10 can both act on the water pipes to achieve the descaling function; while for metal water pipes, the magnetic field output by the liquid pipe descaling device 10 will be shielded by the metal water pipes, and it is the electric field output by the liquid pipe descaling device 10 that acts on the water pipes to achieve the descaling function. Therefore, the descaling effect of the liquid pipe descaling device 10 on plastic water pipes is better than that on metal water pipes.

[0050] In order to improve the descaling effect of water pipes, in one embodiment, Figure 9As shown, the two ends of the resonant coil 12 are respectively marked as the first terminal 1 and the second terminal 2, and a third terminal 3 is led out between the first terminal 1 and the second terminal 2, and the number of coil turns between the first terminal 1 and the third terminal 3 is greater than 0. The first terminal 1 and the third terminal 3 are used to connect the resonant capacitor, thereby realizing the connection between the resonant coil 12 and the resonant capacitor 13.

[0051] In one embodiment, the number of coil turns N1 between the first terminal 1 and the third terminal 3 can be determined based on the diameter of the water pipe and the resonant frequency of the LC oscillation circuit. The number of coil turns N2 between the first terminal 1 and the third terminal 3 is greater than or equal to 1. For example, it is set to 1 turn, 2 turns, etc. The settings of the number of coil turns N1 and the number of coil turns N2 can be determined through experiments to ensure that the set number of coil turns N1 and the number of coil turns N2 can generate an electromagnetic field with a relatively high intensity.

[0052] In actual applications, the winding between the first terminal 1 and the third terminal 3 is recorded as a closed coil, and the winding between the second terminal 2 and the first terminal 3 is recorded as an open coil. The first terminal 1 and the third terminal 3 are connected to the resonant capacitor, and the second terminal 2 is left open and suspended. An alternating current is generated in the resonant coil 12. According to the magnetic effect of the current, an alternating electromagnetic field is generated around the resonant coil 12. When the alternating current is constant, the induced magnetic field and induced electric field generated by the resonant coil 12 are also constant. Therefore, the magnetic core assembly 11 mounted on the water pipe can transmit the electromagnetic field generated by the resonant coil 12 to the magnetic core assembly 11 under the high magnetic permeability effect. At this time, the magnetic core assembly 11 can be regarded as the primary winding, and the water pipe can be regarded as the secondary winding. The electromagnetic field generated by the primary winding generates an alternating electromagnetic field in the secondary winding. The alternating electromagnetic field acts on the water pipe to achieve the effect of descaling.

[0053] In actual applications, although the non-metallic material has very little obstruction to the electromagnetic field of the magnetic core component 11, increasing the current of the resonant coil 12 alone can achieve a better descaling effect, but adopting this solution will increase power consumption. For this reason, the material of the water pipe on which the magnetic core component 11 is mounted can be metal.

[0054] It is understandable that if the electric field strength generated on the water pipe surface is weak, the electromagnetic field strength reaching the interior of the water pipe will also be weak, thus failing to achieve a good descaling effect. This is especially true when the water pipe is made of metal. The magnetic field generated by the resonant coil 12 is almost shielded by the water pipe. However, due to the alternating electric field, a certain amount of charge is generated on the water pipe surface. Without considering the effect of the water pipe being grounded, an equal amount of opposite charge is generated inside the water pipe, thereby generating an electric field of equal magnitude acting on the medium within the water pipe. When considering the effect of the water pipe being grounded, since most of the water pipe is made of iron alloy and has a certain conductivity, a portion of the charge generated by the water pipe is transferred to the ground, which will reduce the electric field strength inside the water pipe to a certain extent. Therefore, without increasing power consumption, a non-closed coil is introduced in this embodiment to increase the electric field strength generated by the coil, resulting in a stronger electric field inside the water pipe, thereby achieving a better descaling effect.

[0055] In this embodiment, the second and third terminals 2 and 3 of the resonant coil 12 are non-closed coils, which can increase the electric field strength generated by the resonant coil 12. Specifically, the electric field strength E generated by the resonant coil 12 is calculated as K*N2*E1, where K is a positive proportional coefficient and E1 is the induced electric field strength generated by the first and third terminals 1 and 3 of the resonant coil 12. The magnitude of the electric field strength generated by the resonant coil 12 is proportional to the number of turns N2 of the non-closed coil in the resonant coil 12. Because the second terminal 2 corresponding to the non-closed coil is in an open, non-closed state, the non-closed coil does not generate current. Based on the power P = U*I, where I = 0, it can be determined that the addition of the non-closed coil does not increase power consumption. Therefore, the electric field strength can be increased without increasing power consumption. Furthermore, according to McVeys' electromagnetic theory, the alternating electric field will generate a vortex magnetic field within the water pipe, and the induced magnetic field strength within the pipe will also be appropriately increased. Therefore, the introduction of the non-closed coil can significantly increase the electric field strength with almost no increase in power consumption, reducing energy waste. On this basis, the introduced non-closed coil liquid pipe descaling device can output a stronger magnetic field and a stronger electric field. For plastic water pipes, the magnetic field intensity and electric field intensity acting on the water pipes are increased without increasing power consumption, and are greater than the magnetic field intensity and electric field intensity output by the liquid pipe descaling device with only a closed coil, thereby improving the water pipe descaling effect; for metal water pipes, the electric field intensity acting on the water pipes is increased without increasing power consumption, and is greater than the electric field intensity output by the liquid pipe descaling device with only a closed coil, thereby improving the water pipe descaling effect.

[0056] Figure 10 4 is a structural block diagram of a liquid processor according to an embodiment of the present invention.

[0057] like Figure 10As shown, the liquid processor 20 includes a signal generator 21 and the liquid pipe descaling device 10 of the above embodiment, wherein the signal generator 21 is electrically connected to the liquid pipe descaling device 10, and the signal generator 21 is configured to apply a pulse signal to the LC oscillation circuit, so that the LC oscillation circuit works. When the LC oscillation circuit works, the resonant coil 12 can generate an alternating current, and the alternating current generates an alternating electromagnetic field when flowing through the magnetic core component 11, wherein the resonant frequency and phase of the multiple magnetic cores in the magnetic core component 11 are kept consistent, and the electromagnetic fields of the multiple magnetic cores of the magnetic core component 11 can achieve resonance superposition, thereby outputting a stronger electromagnetic field. The output alternating electromagnetic field acts on the medium in the liquid pipe, can realize the descaling function, and achieve better descaling effect.

[0058] The liquid pipe descaling device and liquid processor of the embodiment of the present invention configure an LC oscillation circuit to keep the resonant frequency and phase of multiple magnetic cores consistent, so that multiple electromagnetic fields can be resonated and superimposed, thereby enhancing the strength of the output electromagnetic field and improving the descaling effect.
