[0034] like Figure 5As shown, an on-off switch 21 is arranged on the circuit connecting the electrolytic electrode to the first pole of the first power supply 19. When the electrolytic electrode releases active ions in the liquid medium to be treated, the electrolytic electrode is connected to the power supply through the on-off switch 21. When the electrolytic electrode is reversed for descaling, the electrolytic electrode is disconnected from the power supply through the on-off switch 21. This is the prior art for reversed descaling.

[0035] like Figure 1 As shown, a rotatable and adjustable-distance electrode group with the same yin and different yang includes a first electrode 1, a second electrode 2, a third electrode 3, a fourth electrode 4, a fifth electrode 5, a sixth electrode 6 and a seventh electrode 7. The first electrode 1, the second electrode 2, the third electrode 3, the fourth electrode 4 and the fifth electrode 5 are descaling electrodes, the sixth electrode 6 and the seventh electrode 7 are electrolysis electrodes, the first electrode 1, the third electrode 3 and the fifth electrode 5 are respectively connected to the second pole of a first power supply 19 and the second pole of a second power supply 20, the second electrode 2 and the fourth electrode 4 are connected to the first pole of the second power supply 20, the sixth electrode 6 and the seventh electrode 7 are connected to the first pole of the first power supply 19, the sixth electrode 6 and the second electrode 2 are respectively located on both sides of the first electrode 1, the fourth electrode 4 and the seventh electrode 7 are respectively located on both sides of the fifth electrode 5, and the second electrode 2 and the fourth electrode 4 are respectively located on both sides of the third electrode 3.

[0036] The first electrode 1, the second electrode 2, the third electrode 3, the fourth electrode 4 and the fifth electrode 5 are all made of titanium plates or titanium ruthenium iridium plates. The sixth electrode 6 and / or the seventh electrode 7 are made of electrolytic electrodes, which are commonly used electrolytic plates such as zinc, aluminum, copper, iron, and tin. When the material of the electrolytic electrode is aluminum, the electrolytic plate is used to release aluminum ions into the liquid medium to be treated, and the aluminum ions are used to form aluminum-based flocculation groups in the liquid medium to be treated; when the material of the electrolytic electrode is zinc, the material of the electrolytic cell is iron or iron alloy, and the electrolytic plate is used to release zinc ions into the liquid medium to be treated, and the zinc ions are used to deposit a protective film in the electrolytic cell.

[0037] In this embodiment, the distance between the first electrode 1 and the sixth electrode 6 is smaller than the distance between the first electrode 1 and the second electrode 2, and the distance between the fifth electrode 5 and the seventh electrode 7 is smaller than the distance between the fifth electrode 5 and the fourth electrode 4, so as to reduce the energy consumption of electrolysis and improve the descaling efficiency compared with the descaling efficiency of the same power.

[0038] The upper end of each descaling electrode and electrolysis electrode is connected to a rotating assembly, which is used to drive the descaling electrode and the electrolysis electrode to rotate synchronously. The distance between two adjacent descaling electrodes and between the electrolysis electrode and the descaling electrode that rotate synchronously changes. The change in distance is used to adjust the adsorption efficiency or electrolysis rate between the anode and cathode plates. By changing the distance between the anode and cathode by rotation, the problem of increased voltage between the electrodes due to low conductivity and the need to stop the machine for manual adjustment of the distance during electrosorption can be solved. At the same time, the setting of common cathode and different anode can enhance the reducibility of the cathode of electrosorption.

[0039] The rotating assembly is used to drive the descaling electrode and the electrolysis electrode to rotate synchronously and also has the function of reverse pole descaling. In normal operation, the first electrode 1, the third electrode 3 and the fifth electrode 5 are cathodes, the second electrode 2 and the fourth electrode 4 are anodes, and the sixth electrode 6 and the seventh electrode 7 are anodes. After the reverse pole, the first electrode 1, the third electrode 3 and the fifth electrode 5 are anodes, the second electrode 2 and the fourth electrode 4 are cathodes, and the anodes of the sixth electrode 6 and the seventh electrode 7 stop working, which does not affect the reverse pole descaling. During the descaling process, the rotating assembly drives the descaling electrode and the electrolysis electrode to rotate synchronously to achieve reciprocating swing to enhance the descaling efficiency and speed of the electrode during reverse pole descaling.

[0040] like Figure 2 and Figure 3 As shown, the rotating assembly includes a rotating sleeve 8, and the outer periphery of the rotating sleeve 8 is rotatably sleeved on the mounting seat 11, the mounting seat 11 is fixedly installed to a preset position, an electrode terminal 10 is fixedly arranged inside the rotating sleeve 8, one end of the electrode terminal 10 can be detachably installed with a descaling electrode or an electrolysis electrode, one end of the rotating sleeve 8 is connected to a power unit, and the power unit is used to drive the rotating sleeve 8 and the electrode terminal 10 to rotate synchronously. In this embodiment, the outer periphery of the rotating sleeve 8 is rotatably sleeved on the mounting seat 11 through a bearing 9, an insulating pad 12 is sleeved on the inner ring of the rotating sleeve 8, and the outer periphery of the electrode terminal 10 is fixedly sleeved in the insulating pad 12.

[0041] like Figure 1 and Figure 2 As shown, each descaling electrode is equipped with a rotating sleeve 8, and the execution end of the power unit synchronously drives multiple rotating sleeves 8 to rotate through a connecting rod mechanism. The connecting rod mechanism includes a first support rod 13, and a connecting pin 14 is arranged on the first support rod 13, one end of the connecting pin 14 is connected to the execution end of the power unit, and multiple joint pull rods 15 are installed on the first support rod 13, and one end of each joint pull rod 15 is fixedly connected to the side wall of a rotating sleeve 8.

[0042] The joint pull rod 15 includes a fixed seat, one end of which is connected to the first support rod 13, and the other end of the fixed seat is provided with a ball socket, in which a joint ball is connected in a rolling manner, and the outer periphery of the joint ball is connected to the side wall of the rotating sleeve 8 through a rod body, so that when the first support rod 13 swings, the fixed seat can rotate relative to the rod body, such as Figure 4As shown, the power unit includes a linear drive 16, which is a push rod cylinder or a linear motor in the prior art. The linear drive 16 is fixedly installed at a preset position. A slide plate 17 is provided at the execution end of the linear drive 16, and a slide groove 171 is provided on the slide plate 17. A slide rod 18 is provided in the slide groove 171, and the slide rod 18 is a T-shaped structure. One end of the slide rod 18 is slidably connected to the slide plate 17, and the other end of the slide rod 18 is rotatably connected to one end of the connecting pin 14 after passing through the slide groove 171. When in use, the execution end of the linear drive 16 extends or retracts to drive the slide plate 17 to slide linearly. When the slide plate 17 slides linearly, the first support rod 13 can be driven to slide through the slide rod 18 and the connecting pin 14, and the sliding trajectory of the first support rod 13 is arc-shaped due to the influence of the connecting sleeve. The slide groove 171 is used to release the displacement in the vertical direction so that the first support rod 13 can drive multiple rotating sleeves 8 to rotate synchronously.

[0043] Working process of a rotatable and adjustable-distance electrode group with the same yin and different yang:

[0044] When the electrode group performs water treatment, the first electrode 1, the third electrode 3 and the fifth electrode 5 are cathodes, the second electrode 2 and the fourth electrode 4 are anodes, the sixth electrode 6 and the seventh electrode 7 are anodes, and the materials of the first electrode 1, the second electrode 2, the third electrode 3, the fourth electrode 4 and the fifth electrode 5 are ruthenium iridium titanium plates, the material of the sixth electrode 6 is zinc, and the material of the seventh electrode 7 is aluminum, wherein the first electrode 1, the third electrode 3 and the fifth electrode 5 are respectively connected to the second pole of the first power supply 19 and the second pole of the second power supply 20, the second electrode 2 and the fourth electrode 4 are connected to the first pole of the second power supply 20, the sixth electrode 6 and the seventh electrode 7 are connected to the first pole of the first power supply 19, the first electrode 1 is an electrolysis power supply, and the second power supply 20 is a descaling power supply. Under the action of the electric field, the dissolved salt ions and the charged pollutant particles in the water migrate to the electrodes of opposite charge and are retained and adsorbed on the double electric layer on the surface of the corresponding plate, and the cathode undergoes a reduction reaction, and the adsorbed calcium and magnesium ions combine with hydroxide and carbonate to form calcium hydroxide and calcium carbonate, which are attached to the cathode plate.

[0045] After the polarity reversal, the first electrode 1, the third electrode 3 and the fifth electrode 5 are anodes, the second electrode 2 and the fourth electrode 4 are cathodes, and at the same time, the anodes of the sixth electrode 6 and the seventh electrode 7 are disconnected and stop working by the on-off switch 21, so that an oxidation reaction occurs at the anode, causing the calcium hydroxide and calcium carbonate originally adsorbed on the first electrode 1, the third electrode 3 and the fifth electrode 5 to fall off. After the polarity reversal descaling reaction is completed, the first electrode 1, the third electrode 3 and the fifth electrode 5 are restored to be cathodes, and the second electrode 2 and the fourth electrode 4 are restored to be anodes.

[0046] When the first electrode 1, the third electrode 3 and the fifth electrode 5 are cathodes, the second electrode 2 and the fourth electrode 4 are anodes, the sixth electrode 6 and the seventh electrode 7 are anodes, and the cathodes of the sixth electrode 6 and the seventh electrode 7 are also the first electrode 1, the third electrode 3 and the fifth electrode 5 of the ruthenium iridium electrode from the loop. The electrolysis of the sixth electrode 6 and the seventh electrode 7 is realized, and while the electrolytic zinc electrode and the aluminum electrode are formed, the adsorption capacity and reaction capacity of the calcium and magnesium ions of the cathodes of the first electrode 1, the third electrode 3 and the fifth electrode 5 are also enhanced.

[0047] In this embodiment, the voltage of the first power supply 19 is 0-24V, the voltage of the second power supply 20 is 0-36V, when the first electrode 1, the third electrode 3 and the fifth electrode 5 are cathodes, the second electrode 2 and the fourth electrode 4 are anodes and connected to the positive electrode of the second power supply 20, the sixth electrode 6 and the seventh electrode 7 are anodes and connected to the positive electrode of the first power supply 19, and the anodes of the first electrode 2 and the fourth electrode 4 form a loop with the first electrode 1, the third electrode 3 and the fifth electrode 5 of the ruthenium-iridium electrode. At the same time, the anodes of the sixth electrode 6 and the seventh electrode 7 form a loop with the first electrode 1, the third electrode 3 and the fifth electrode 5 of the ruthenium-iridium electrode, and the electrolysis of the sixth electrode 6 and the seventh electrode 7 is realized. While forming the electrolytic zinc electrode and the aluminum electrode, the current electric field of the loop of the first electrode 1, the third electrode 3 and the fifth electrode 5 is also enhanced, and the adsorption capacity and reaction capacity of the cathode of calcium and magnesium ions are correspondingly increased.

[0048] When the conductivity of water is low, the distance between the ruthenium and iridium electrodes remains unchanged, which causes the resistance between the cathode and cathode to increase, the current to decrease, and the voltage to increase. As the current decreases, the electric field between the cathode and cathode also decreases, which affects the adsorption capacity of calcium and magnesium ions in water, while also causing the power of the equipment to increase, affecting the life of the electrodes. By changing the distance between the electrodes by rotating the assembly, the resistance between the cathode and cathode is reduced, and the conductivity between the cathode and cathode is ensured, thereby achieving the adsorption capacity of calcium and magnesium ions in water under different conductivity conditions and reducing the power consumption of the equipment.

[0049] In this embodiment, the sixth electrode 6 releases zinc ions into the water through electrolysis, which preferentially combine with hydroxide in the water to form zinc hydroxide precipitation (zinc ions are more active than iron) and are deposited to form a protective film, thereby protecting the steel surface from further corrosion. The seventh electrode 7 releases aluminum ions into the water through electrolysis and forms aluminum flocculation groups with water, which has a strong coagulation and precipitation effect on colloidal impurities and suspended particles in the water.

[0050] The control method of this embodiment is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. This article is mainly used to protect mechanical devices. The control method and circuit connection are not explained in detail in this article.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
