when the pressure value detected by the closed pressure sensor 703 has a larger change range, the electrolytic electrode 601 needs to be replaced, in the replacement, the driving motor 618 is electrified and drives the internal thread sleeve 615 to rotate through the sleeve transmission gear 617 and the sleeve gear 616, at the moment, the internal thread sleeve 615 drives the electrode lifting seat 603 to linearly move along the axis of the guide screw 607, the electrode lifting seat 603 moves upwards and drives the electrode fixing seat 602 and the electrolytic electrode 601 which are connected with the electrode lifting seat 603 through the suspension plate 609 to move upwards, the driving motor 618 is powered off to stop working after the electrolytic electrode 601 is completely separated from the sewage electrolytic tank 3, then the telescopic rod 612 is electrified and started to drive the powerful suction electromagnet 613 to approach the electrode fixing seat 602, after the powerful suction electromagnet 613 is attached to the electrode fixing seat 602, the powerful suction electromagnet 613 is driven to reset after the powerful suction electromagnet 613 is adsorbed, the powerful suction electromagnet 613 separates the electrode fixing seat 602 from the electrode lifting seat 603 and the standby electrode placing seat 604, and then the rotary motor 620 is electrified and drives the suspension rotary shaft 619 to rotate, so that the positions of the two electrolytic electrodes 601 are exchanged by half a circle;
after the positions of the two electrolytic electrodes 601 are exchanged, the telescopic rod 612 is started again to drive the two electrolytic electrodes 601 adsorbed by the powerful absorbing electromagnet 613 to move, so that the electrolytic electrodes 601 after the exchange positions are in butt joint with the electrode lifting seat 603 and the standby electrode placing seat 604, and finally the driving motor 618 is started reversely, so that the electrode lifting seat 603 is driven by the internal thread sleeve 615 to move downwards to reset, the replaced electrolytic electrodes 601 enter the sewage electrolytic tank 3 to continue to carry out electrolytic purification on sewage, manual operation is not needed in the whole process, the sewage electrolytic tank 3 is not required to be powered off, the normal treatment process of the sewage is not influenced, and only workers need to replace the replaced electrolytic electrodes 601 on the standby electrode placing seat 604.
