[0025] Reference Figure 1 The embodiment of the utility model provides an electrolytic cell 300 reversal descaling device, including a relay 100; a three-way solenoid valve 200; an electrolytic cell 300, wherein the positive electrode of the electrolytic cell 300 is respectively connected to the positive normally closed end and the negative normally open end of the relay 100, and the negative electrode of the electrolytic cell 300 is respectively connected to the negative normally closed end and the positive normally open end of the relay 100; and a switch module 400, wherein the switch module 400 is respectively connected to the relay 100 and the three-way solenoid valve 200. The descaling device for the electrolytic cell 300 in the present embodiment switches the polarity of the positive and negative electrodes of the electrolytic cell 300 through the relay 100 and the switch module 400, so that the anode and cathode of the electrolytic cell 300 are interchanged. After the polarity is interchanged, the on-off of the three-way solenoid valve 200 is adjusted to realize the switching of the acid and alkaline water output pipelines. By periodically switching the polarity of the electrolytic cell 300 and the flow direction of the acid and alkaline water, the alkaline scale deposited in the electrolytic cell 300 is dissolved, thereby keeping the electrolytic cell 300 clean and in normal use.

[0026] It should be noted that the positive pole of the electrolytic cell 300 is connected to the normally closed end of the positive pole and the normally open end of the negative pole of the relay 100, and the negative pole of the electrolytic cell 300 is connected to the normally closed end of the negative pole and the normally open end of the positive pole of the relay 100. Through this connection method, the polarity of the electrolytic cell 300 can be changed by triggering the relay 100. When the relay 100 receives the on or off signal of the switch module 400, the polarity of the electrolytic cell 300 is reversed, changing the flow direction of the acid and alkaline water, and dissolving the alkaline scale deposited in the electrolytic cell 300. The switch module 400 is used to control the relay 100 and the three-way solenoid valve 200. The three-way solenoid valve 200 is used to adjust the flow direction of the liquid so that the acid and alkaline water can switch the path during the cleaning and operation of the electrolytic cell 300. When the electrolytic cell 300 needs to be descaled, the switch module 400 activates the relay 100, changes the polarity of the electrolytic cell 300 and adjusts the output pipeline of the acid and alkaline water of the three-way solenoid valve 200, thereby removing the alkaline scale in the electrolytic cell 300 and the pipeline.

[0027] The relay 100 is provided with a control power supply 110, the positive pole of the control power supply 110 is connected to the relay 100 through the switch module 400, and the negative pole of the control power supply 110 is connected to the three-way solenoid valve 200 by a wire. It should be noted that the positive pole of the relay 100 is connected to the positive pole of the control power supply 110, so that the relay 100 can adjust the on and off of the control power supply 110, thereby changing the polarity of the electrode in the electrolytic cell 300, and the negative pole of the control power supply 110 is connected to the relay 100 through the switch module 400, so that the relay 100 can receive the signal of the switch module 400, and the operation of the relay 100 is triggered by adjusting the on and off of the control power supply 110, so that the switch module 400, the three-way solenoid valve 200 and the electrolytic cell 300 change the polarity and adjust the flow direction of the acid and alkali water, so as to ensure the accuracy and reliability of the reverse polarity descaling process. In addition, by accurately controlling the polarity of the electrode in the electrolytic cell 300, the accumulation of alkaline scale can be effectively prevented, and the service life of the electrolytic cell 300 can be extended.

[0028] The relay 100 is provided with an electrolytic power source 120, and the positive and negative electrodes of the electrolytic power source 120 are connected to the common terminal of the relay 100. It should be noted that the polarity of the electrolytic power source 120 is adjusted by the relay 100 to achieve precise control of the descaling process of the electrolytic cell 300, thereby ensuring the accuracy and reliability of the operation.

[0029] The switch module 400 is provided with a reversing control switch 410, one end of the reversing control switch 410 is connected to the positive pole of the relay 100, the other end of the reversing control switch 410 is connected to the positive pole of the control power supply 110, and the negative pole of the relay 100 is respectively connected to the negative pole of the relay 100 and the negative pole of the three-way solenoid valve.

[0030] It should be noted that, under normal circumstances, the common terminal of the relay 100 is connected to the normally closed terminal, and the normally open terminal is turned off. When the reversing control switch 410 is turned on, the relay 100 is energized. At this time, the common terminal of the relay 100 is connected to the normally open terminal, and the normally closed terminal is turned off. When the relay 100 is in the above state, the positive and negative poles of the electrolytic cell 300 will change, thereby realizing the positive and negative pole conversion of the electrolytic cell 300.

[0031] A water flow control switch 420 is also connected between the three-way solenoid valve 200 and the reversing control switch 410. The positive pole 230 and the negative pole 240 of the three-way solenoid valve are both connected to one end of the water flow control switch 420, and the other end of the water flow control switch 420 is connected to the reversing control switch 410.

[0032] It should be noted that, when the reversing switch realizes the conversion of the positive and negative poles of the electrolytic cell 300, the acid and alkaline water flowing out of the water outlet of the electrolytic cell 300 will also change. At this time, the water flow control switch 420 is pressed to realize the conversion of the flow direction of the acid and alkaline water of the three-way solenoid valve 200. Specifically, the water flow control switch 420 is connected to the three-way solenoid valve 200 to change the on-off state of the positive pole 230 of the three-way solenoid valve and the negative pole 240 of the three-way solenoid valve, thereby adjusting the flow direction of the acid and alkaline water of the three-way solenoid valve 200.

[0033] The three-way solenoid valve 200 is provided with a first water outlet 210, a second water outlet 220, and a third water outlet 230. One end of the first water outlet 210 and the second water outlet 220 are connected to the electrolytic cell 300, and the other end of the first water outlet 210 and the second water outlet 220 are connected to the third water outlet 230.

[0034] It should be noted that when one end of the first water outlet 210 and the second water outlet 220 are connected to the electrolytic cell 300, the on-off between the positive pole 230 of the three-way solenoid valve and the negative pole 240 of the three-way solenoid valve is controlled by adjusting the water flow control switch 420, so that the water flowing out of the third water outlet 230 of the three-way solenoid valve 200 continues to be acidic oxidizing potential water, thereby realizing precise diversion and convergence of acid and alkaline water.

[0035] Reference Figure 1 and Figure 2The electrolytic cell 300 is provided with a first through hole 310 and a second through hole 320, and the first water outlet 210 is inserted into the electrolytic cell 300 through the first through hole 310, and the second water outlet 220 is inserted into the electrolytic cell 300 through the second through hole 320. It should be noted that the first water outlet 210 and the second water outlet 220 are inserted into the electrolytic cell 300 through the first through hole 310 and the second through hole 320, which can accurately control the inflow and discharge of acid and alkaline water, and ensure that the acid water treats the alkaline scale in the electrolytic cell 300, without the need for additional pipes and connectors, and further improves the efficiency of cleaning and maintenance of the electrolytic cell 300.

[0036] Reference Figure 1 and Figure 2 The other end of the electrolytic cell 300 is also provided with a water inlet 330 and a third through hole 340 , and the water inlet 330 is inserted into the electrolytic cell 300 through the third through hole 340 , wherein the other end of the electrolytic cell 300 is the opposite side of one end of the electrolytic cell 300 . It should be noted that one end of the water inlet 330 can be connected to a water supply system, and the other end of the water inlet 330 is inserted into the electrolytic cell 300 through the third through hole 340. The water supply system provides new liquid to flow into the electrolytic cell 300 through the water inlet 330 to maintain the liquid level during the electrolysis process or replenish the consumed electrolyte. By ensuring the stable level of the liquid in the electrolytic cell 300, the continuous operation of the electrolysis process is ensured, and the reaction interruption due to excessively high or low liquid level or the immediate replenishment of acid water during the descaling process of the electrolytic cell 300 is avoided. The concentration of the treated liquid in the electrolytic cell 300 is adjusted to adapt to the reaction conditions of different degrees of alkaline scale, reduce the accumulation of alkaline scale, and extend the service life of the electrolytic cell 300.
