[0032] As Figure 3、 4 As shown in the electrolyte cleaning process, the upper surface of the residual electrode hydraulic lifting mechanism 3 is in contact with the bottom of the residual electrode 11, and after cleaning is completed, part of the electrolyte residue will be left on the upper surface of the residual electrode hydraulic lifting mechanism 3. Because the electrolyte is hard, the electrolyte residue will cause damage to the anode carbon block in the next lifting cycle. The presence of electrolyte residue will also cause uneven stress on the residual electrode carbon block, causing tilting and preventing cleaning work from being performed. Therefore, residue cleaning is particularly important. Considering that the residual electrode hydraulic lifting mechanism 3 reciprocates during production, lifting and resetting are a working cycle, so automatic residue cleaning can be achieved based on the principle of reciprocating motion. Because the electrolyte residue is irregular in shape and has poor flowability, a certain inclination angle is required to make the electrolyte residue automatically fall. Therefore, the device further includes an automatic cleaning device arranged at the top of the residual electrode hydraulic lifting mechanism 3, which includes a top rod 7, a hinge 9 and a top plate 8. The top rod 7 is fixed to the base of the residual electrode hydraulic lifting mechanism 3 and does not change position during lifting and resetting. The top plate 8 is connected to the protective plate of the residual electrode hydraulic lifting mechanism 3 using the hinge 9, and the top plate 8 can rotate freely. In the initial position, the top plate 8 is placed on the side of the top rod 7, forming a 30-degree angle with the upper surface of the residual electrode hydraulic lifting mechanism 3. During the upward lifting of the residual electrode hydraulic lifting mechanism 3, the top plate 8 rotates along the hinge 9 axis due to its own gravity. When the upper surface of the residual electrode hydraulic lifting mechanism 3 is higher than the highest point of the top rod 7, the top plate 8 coincides with the upper surface of the residual electrode hydraulic lifting mechanism 3, forming a plane, thereby lifting the residual electrode 11 to the fixed position. After the electrolyte cleaning process is completed, the residual electrode hydraulic lifting mechanism 3 is lowered. During the lowering process, when the top plate 8 contacts the side of the top rod 7, the top plate 8 begins to rotate. During the rotation process, the electrolyte residue left on the surface of the top plate 8 begins to slide. When the residual electrode hydraulic lifting mechanism 3 is lowered to the initial position, the top plate 8 is rotated to the maximum angle, thereby achieving the purpose of automatic residue cleaning.

[0033] The electrolyte cleaning device for self-adaptive high and low residual electrodes adopts a rock drill 2 to replace manual electrolyte cleaning, thereby achieving the purposes of reducing labor intensity and improving production efficiency. The residual electrode hydraulic lifting mechanism 3 is used to adapt to the elevation of each residual electrode 11, ensuring smooth lifting, fixing and cleaning of the residual electrode 11. The automatic cleaning device is used to achieve automatic residue cleaning without the need for manual secondary cleaning.
