[0049] In some embodiments, the connecting member 5 is a bolt. The first connecting section 42 is provided with a first thread 421, and the second connecting section 43 is provided with a second thread 431.

[0053] In some embodiments, the overcurrent cylinder 1 includes a cylinder body 11, a first fixing flange 12 and a second fixing flange 13.

The first connecting flange 6 is connected to the first fixing flange 12, and the positive electrode plate 2 is clamped between them. The second connecting flange 7 is connected to the second fixing flange 13, and the negative electrode plate 3 is clamped between them. After the first connecting flange 6 and the first fixing flange 12 clamp the positive electrode plate 2 between them, they are connected by bolts and then fastened by nuts to fix the positive electrode plate 2.

[0054] In some embodiments, the positive electrode plate 2 includes a first base ring 21, a first tab 22 and a first adapter piece 23. The first base ring 21 is clamped between the first connecting flange 6 and the first fixing flange 12. The diameter of the inner circumference of the first base ring 21 is less than or equal to the inner wall diameter of the cavity 111, and it will not block the liquid before the liquid enters the cavity 111, ensuring that the liquid can flow to the greatest extent with the inner wall diameter of the cavity 111, improving the electrolysis efficiency. The first tab 22 is connected to the outer circumference of the first base ring 21 and protrudes from the first connecting flange 6, facilitating the connection of the first tab 22 to electricity. One end of the first adapter piece 23 is connected to the inner circumference of the first base ring 21, and the other end abuts against the first connecting section 42. The end of the first adapter piece 23 is provided with a first arc surface 231, and the first arc surface 231 is adapted to the outer wall of the first connecting section 42. The side surface of the first adapter piece 23 along the axis of the metal electrode 4 abuts against the connecting piece 5. The first adapter piece 23 will not completely block the inner wall hole of the first base ring 21, so that the liquid can enter the cavity 111 for circulation.

[0055] In some embodiments, three first adapter pieces 23 are provided, and the three first adapter pieces 23 are evenly distributed along the circumferential circle of the first base ring 21.

[0056] In some embodiments, the negative electrode sheet 3 includes a second base ring 31, a second tab 32, and a second adapter piece 33; the second base ring 31 is clamped between the second connection flange 7 and the second fixing flange 13. The diameter of the inner circumference of the second base ring 31 is less than or equal to the inner wall diameter of the cavity 111, so as not to block the liquid before it enters the cavity 111, ensuring that the liquid can flow through the inner wall diameter of the cavity 111 to the greatest extent and improving the electrolysis efficiency; the second tab 32 is connected to the outer circumference of the second base ring 31 and protrudes from the second connection flange 7, facilitating the connection of the second tab 32 to electricity; one end of the second adapter piece 33 is connected to the inner circumference of the second base ring 31, and the other end abuts against the second connection section 43.

The side of the second adapter piece 33 along the axial direction of the metal electrode 4 abuts against the connector 5. The first adapter piece 23 does not completely block the inner wall hole of the second base ring 31, so that the liquid can flow out of the cavity 111. On the premise of ensuring the current, the first adapter piece 23 can be set to be as small as possible in size.

[0057] In some embodiments, three second adapter pieces 33 are provided, and the three second adapter pieces 33 are evenly distributed along the circumferential circle of the second base ring 31. By evenly distributing the three second adapter pieces 33 along the circumferential circle of the second base ring 31, the three second adapter pieces 33 support and connect the second connection section 43 to form a triangular support, which is more stable and can better ensure the stability of liquid flow, avoiding turbulence and affecting the electrolysis efficiency.

[0058] In some embodiments, a first hollow hole 232 is provided on the first adapter piece 23, and a second hollow hole 332 is provided on the second adapter piece 33. Through the design of the first hollow hole 232 and the second hollow hole 332, the area for liquid to pass through can be increased, and the weight can be reduced and the cost can be lowered.

[0059] The working principle of this flow-through electrolysis device is as follows: After the first connecting flange 6 and the first fixing flange 12 sandwich the positive electrode plate 2 therebetween, they are connected by bolts and tightened by nuts to fix the positive electrode plate 2; after the second connecting flange 7 and the second fixing flange 13 sandwich the negative electrode plate 3 therebetween, they are connected by bolts and tightened by nuts to fix the negative electrode plate 3; the first connecting section 42 and the second connecting section 43 are respectively arranged at both ends of the electrode section 41; two of the connecting members 5 are connected to the first thread 421 and respectively abut against both sides of the positive electrode plate 2, and the other two connecting members 5 are connected to the second thread 431 and respectively abut against both sides of the negative electrode plate 3, so that the two ends of the metal electrode 4 can be positioned by the positive electrode plate 2 and the negative electrode plate 3, realizing the stable connection of the metal electrode 4 at the positive electrode plate 2 and the negative electrode plate 3, further improving the stability and ensuring the reliability of the electrical connection. This flow-through electrolysis device can ensure that after the metal electrode 4 is worn, the electrical connection between the metal electrode 4 and the positive electrode plate 2 and the negative electrode plate 3 is maintained through the connecting member 5, ensuring that the metal electrode 4 can remain in an energized state and improving the reliability and stability of the device.
