[0022] Specifically, the pH value monitoring component 34 includes an alarm lamp 1 (341), an alarm lamp 2 (342), a PLC controller 344, and a pH value sensor 345. On the other side of the inner wall of the electrolytic cell body 1, there is a pH value sensor 345. Outside the electrolytic cell body 1, there is a PLC controller 344. Near the PLC controller 344 on the outside of the electrolytic cell body 1, there is an alarm lamp 1 (341). Near the alarm lamp 1 (341) on the outside of the electrolytic cell body 1, there is an alarm lamp 2 (342).

[0023] By adopting the above technical solution, the pH value of the electrolyte is monitored by the pH value sensor 345, and then the threshold value of the pH value sensor 345 is set by the PLC controller 344. When the pH value sensor 345 detects that the pH value of the electrolyte is too high or too low, at this time, the pH value sensor 345 converts the monitored signal into an electrical signal and transmits it to the PLC controller 344. The PLC controller 344 controls the alarm lamp 1 (341) to give an alarm. Since the zinc block 33 needs to be replaced after being used for a period of time, at this time, the replacement time is set by the PLC controller 344.

By the method of sacrificial anode, the corrosion rate of the inner wall of the electrolytic cell body 1 is reduced by the corrosion of the zinc block 33. Then, the pH value of the electrolyte is monitored by the pH value sensor 345, and then the threshold value of the pH value sensor 345 is set by the PLC controller 344. When the pH value sensor 345 detects that the pH value of the electrolyte is too high or too low, at this time, the pH value sensor 345 converts the monitored signal into an electrical signal and transmits it to the PLC controller 344. The PLC controller 344 controls the alarm lamp 1 (341) to give an alarm. Since the zinc block 33 needs to be replaced after being used for a period of time, at this time, the replacement time is set by the PLC controller 344. When the replacement time of the zinc block 33 is reached, at this time, the alarm lamp 2 (342) will flash, thereby prompting the worker to replace the zinc block 33.

[0031] Specifically, the connection between the screw rod 25 and the mounting block 28 is rotationally connected through a bearing, and the connection between the rotating rod 29 and the mounting block 28 is rotationally connected through a bearing.

[0032] By adopting the above technical solution, the setting of this structure can avoid the problem of gear meshing misalignment of the first bevel gear 26 and the second bevel gear 27.

[0033] During the use of this embodiment, when the electrolytic cell body 1 has a furnace leakage problem, at this time, the asbestos lining cloth is put on the iron needle 21. By pressing the asbestos lining cloth against the notch of the electrolytic cell body 1 and rotating the turning handle 210, the rotation of the turning handle 210 drives the rotation of the rotating rod 29. The rotation of the rotating rod 29 drives the rotation of the second bevel gear 27. The rotation of the second bevel gear 27 drives the rotation of the first bevel gear 26. The rotation of the first bevel gear 26 drives the rotation of the screw rod 25. The rotation of the screw rod 25 drives the adjusting block 22 to slide outward, so that the mounting block 28 abuts against the other inner wall of the electrolytic cell body 1, thus realizing the treatment of the furnace leakage of the electrolytic cell body 1. When the adjusting block 22 slides, it will drive the sliding rod 24 to slide inside the through hole 23, thereby improving the stability of the sliding process of the adjusting block 22.

[0036] Working principle and usage process of the utility model: When the utility model is in use, first, one end of the connecting wire 31 is connected to the inner wall of the electrolytic cell body 1, and the other end is connected to the zinc block 33. Then, the zinc block 33 is placed in the electrolyte. By the method of sacrificial anode, the corrosion of the zinc block 33 is used to reduce the corrosion rate of the inner wall of the electrolytic cell body 1. Then, the pH value sensor 345 monitors the pH value of the electrolyte, and the PLC controller 344 sets the threshold value of the pH value sensor 345. When the pH value sensor 345 detects that the pH value of the electrolyte is too high or too low, at this time, the pH value sensor 345 converts the monitored signal into an electrical signal and transmits it to the PLC controller 344, and the PLC controller 344 controls the alarm lamp 341 to give an alarm. Since the zinc block 33 needs to be replaced after being used for a period of time, at this time, the PLC controller 344 sets the replacement time. When the replacement time of the zinc block 33 is reached, the alarm lamp 342 will flash, so as to prompt the worker to replace the zinc block 33. When the electrolytic cell body 1 has a problem of furnace leakage, at this time, the asbestos lining cloth is put on the iron needle 21, and the asbestos lining cloth is abutted against the notch of the electrolytic cell body 1. The rotary handle 210 is rotated, and the rotation of the rotary handle 210 drives the rotating rod 29 to rotate. The rotation of the rotating rod 29 drives the bevel gear 27 to rotate. The rotation of the bevel gear 27 drives the bevel gear 26 to rotate. The rotation of the bevel gear 26 drives the screw rod 25 to rotate. The rotation of the screw rod 25 drives the adjusting block 22 to slide outwards, so that the mounting block 28 abuts against the other inner wall of the electrolytic cell body 1, thereby realizing the treatment of the furnace leakage of the electrolytic cell body 1. When the adjusting block 22 slides, it will drive the slide bar 24 to slide inside the through hole 23, thereby improving the stability of the sliding process of the adjusting block 22.
