[0029] Furthermore, the pole 37 on the left is an anode pole, and the pole 37 on the right is a cathode pole, which makes it easier for workers to distinguish the properties of the pole 37 .

[0030] Furthermore, a stirring rod is fixedly provided at the end of the main shaft of the first motor 2. The stirring rod is located inside the electrolytic tank body 1 to stir the high-chlorine solution and accelerate the overflow of chlorine. A placement groove is provided on the side of the mounting frame 31 facing the inside of the electrolytic tank body 1 to store the inner tube 32 and connect it to the electrolytic tank body 1.

[0035] Working principle effect;

[0036] The staff introduces the high-chlorine solution into the electrolytic tank body 1 through the addition port (not shown in the figure), and the first motor 2 drives the stirring rod at the end of the main shaft to stir the high-chlorine solution in the electrolytic tank body 1, thereby accelerating the release of chlorine, delaying the consumption progress of the pole 37, and extending the service life. After the pole 37 is consumed, the staff directly extracts the inner tube 32 inside the mounting frame 31 of the electrolytic pole replacement component 3, lifts the sealing cap 34 from the outside of the tube head 33, and takes out the inner tube 32 from the inside of the mounting frame 31, disassembles the pole 37, and 37 is replaced. After the replacement is completed, the inner tube 32 and the pole 37 are placed into the interior of the mounting frame 31, and the threaded shaft 35 in the middle position of the sealing cap 34 is rotated clockwise, and the threaded shaft 35 gradually enters the interior of the sealing cap 34, and the first transmission rod 36 at the other end of the threaded shaft 35 is pushed to push the pole 37 to start opening. In conjunction with the rotation of the second transmission rod 38, the pole 37 is controlled to open from the inside of the inner tube 32 and the mounting frame 31 and enter the interior of the electrolytic tank body 1, and the pole 37 is inserted into the interior of the electrolytic tank body 1 to fully contact with the high chlorine solution.

[0037] At the same time, during the electrochemical dechlorination process of the electrolytic tank body 1, the control switch of the second motor 4 can be turned on to control the reciprocating screw 5 at the end of the main shaft of the second motor 4 to rotate, and the outer lifting slider 6 can be controlled to move up and down outside the vertical axis, thereby controlling the outer lifting trough frame 7 to start lifting. After the lifting trough frame 7 is lifted, part of the high-chlorine solution can be lifted. During the lifting process, the high-chlorine solution will slowly flow back to the inside of the electrolytic tank body 1 through the water outlet pipe 8 for circulation, thereby accelerating the release of chlorine.

[0038] After all the treatments are completed, the waste is discharged through an outlet pipe (not shown in the prior art diagram).
