Description

Technical Field

[0001] A method for stabilizing the distance and relative position of the anode and cathode within an electrolytic cell. Technical Background

[0002] Currently, the technical requirements for enhancing the solution circulation effect within electrolytic cells in various metal electrolytic production systems are becoming increasingly stringent. Some organizations have developed technologies and methods to enhance the internal circulation of solutions within electrolytic cells. However, under a certain intensity of internal circulation, the anode and cathode within the electrolytic cell will sway with the rapid flow of the solution. This can cause serious quality problems and production accidents, such as numerous inter-electrode short circuits and anode / cathode position shifts. Therefore, the anode / cathode swaying problem has hindered the further application of internal circulation technology within electrolytic cells. Summary of the Invention

[0003] This invention addresses the aforementioned problem of anode and cathode swaying within an electrolytic cell by providing a method for stabilizing the distance and relative position of the anode and cathode within the electrolytic cell.

[0004] This invention is achieved through the following technical solution, characterized in that:

[0005] The fixing rod is made of insulating material and has slots or screws for fixing the anode and cathode. The upper edge of the anode and cathode is determined by the conductive rod, and the lower edge of the anode and cathode is fixed by the fixing rod to achieve a stable relative position of the anode and cathode.

[0006] The fixing rod can be set in a fixed position inside the electrolytic cell. When the anode and cathode are placed into the electrolytic cell, the lower edge of the anode and cathode is locked in the corresponding slot of the fixing rod at a certain position. Alternatively, the fixing rod can be connected to the anode and cathode and fixed in the electrolytic cell. Both methods can achieve the fixation of the lower edge of the anode and cathode inside the electrolytic cell.

[0007] The fixing rod can also be a short rod fixed to the anode and cathode. When the anode and cathode are placed in the electrolytic cell, the short rod rests on the adjacent anode and cathode to fix the distance between them. The short rods on the electrodes at both ends of the electrolytic cell are supported on the inner wall of the electrolytic cell to fix the electrodes inside the cell. Attached Figure Description

[0011] Copper and arsenic removal electrolytic cells:

[0012] The anode uses a grid-type lead-clad titanium insoluble anode. Each anode has 20 vertically arranged lead-clad titanium anode strips. The anode strips are covered with anode bags to prevent contact with suspended matter. The lower edge of the anode is clamped on a plastic clip. Short rods, each 100mm long and 20mm in diameter, extending towards the cathode are installed on both sides of the plastic clip.

[0013] The cathode is a composite cathode composed of multiple small cathode sheets: 90 cathode titanium sheets, each 1100mm long, 25mm wide, and 0.8mm thick, are arranged in parallel face-to-face with a 10mm interval. The upper edge is fixed to the cathode connecting frame, and the lower edge is fixed to the plastic clip.

[0014] 28 cathodes and 29 anodes are arranged alternately in the electrolytic cell with a 100mm gap between them. Short rods on the anode plastic clips are supported on the plastic clips at the lower edge of the cathodes to fix the gap between them. Short rods on the outward side of the anodes at both ends of the cell are supported on the cell wall to fix the anodes and cathodes inside the cell and prevent them from swaying.

[0015] During the insoluble anode electrolytic production process for copper and arsenic removal, the circulating flow rate in the solution reached over 100 mm / s, and there was no swaying phenomenon at the anode and cathode in the tank. The arsenic removal rate reached 90%, and the DC efficiency reached 88%, achieving the expected results for copper and arsenic removal.

Claims

1. Use insulating material to make a fixing rod. The fixing rod is equipped with slots or screws to fix the anode and cathode. The relative position of the anode and cathode is determined by the conductive rod at the upper edge and the fixing rod at the lower edge of the anode and cathode, so as to achieve a stable relative position of the anode and cathode.

2. The fixing rod can be set in a fixed position inside the electrolytic cell. When the anode and cathode are placed into the electrolytic cell, a certain position of the lower edge of the anode and cathode is locked in the corresponding slot of the fixing rod, or the fixing rod is connected to the anode and cathode and fixed in the electrolytic cell. Both methods can achieve the fixation of the anode and cathode inside the electrolytic cell.

3. The fixing rod can also be a short rod fixed to the anode and cathode. When the anode and cathode are placed in the electrolytic cell, the short rod rests on the adjacent anode and cathode to fix the distance between them. The short rods on the electrodes at both ends of the electrolytic cell are supported on the inner wall of the electrolytic cell to fix the electrodes inside the cell.
