Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to a device for drawing lines on anode guide rods in the field of electrolytic aluminum production. Background Art

[0002] During the aluminum electrolysis production process, the anode will be gradually consumed. After reaching the service life, a new anode needs to be replaced. The new anode loaded into the aluminum electrolytic cell is not consumed within 16 hours. The bottom of the new and old anodes in the electrolytic cell is always at the same level to maintain the consistency of the distance between the bottom of each anode and the bottom of the electrolytic cell. This is the basic process requirement in the electrolytic aluminum production process. When loading a new anode, because the temperature of the new anode is lower than that of the old anode, the old anode is consumed more slowly, so it is necessary to manually increase its pole distance by 20mm higher than the pole distance of the normally working anode. Before the residual anode is replaced, a chalk line will be drawn at the lowest edge of the horizontal busbar corresponding to the residual anode guide rod to ensure that the height of the newly loaded anode is 20mm higher than other anodes in the cell to meet the requirements of stable production. During normal operation, the operator who draws the marking line needs to climb to the top of the electrolytic cell and hold a brush (such as chalk) to complete it. The operator has the potential safety hazard of falling from a height during the process of raising and lowering the cell cover, and climbing up and down takes a lot of time and is inefficient.

[0003] At the same time, as the aluminum electrolysis production process continues, the large horizontal busbars and anode guide rods of the electrolytic cell will gradually and slowly drop as the anodes are consumed. After the horizontal busbar of the electrolytic cell drops for a period of 18 days, the large horizontal busbars of the anodes of the electrolytic cell need to be transferred and lifted. When the large horizontal busbars of the anodes of the electrolytic cell are transferred and lifted, the anodes will be pressed when the busbar frame falls due to the looseness of some small box clamps due to instability. Sometimes, the diameter of some anode guide rods does not reach 140mm, and the locking mechanism of the busbar frame cannot completely lock the anode guide rods. During the lifting and transfer operation, the anodes will slide down, or the small box clamps will lock the anode guide rods and the anodes will be loaded. Once the phenomenon of pressed pole, slipped pole and stripped pole occurs, the anode bottoms of all anodes in the electrolytic cell cannot be kept at the same level, and the electrolytic cell will experience voltage fluctuations or even develop into a sick cell, which seriously affects the stable production and efficiency improvement of aluminum electrolysis; when pressed pole, slipped pole and stripped pole occur during the lifting operation, the electrolytic production personnel need to make technical height adjustments to the pressed pole, slipped pole and stripped pole in time. The reference for the adjustment is the marking line drawn with chalk at the bottom edge of the horizontal busbar and the connection between the pressed pole anode, slipped pole anode and stripped pole anode guide rod before the lifting operation. These marking lines also need to be drawn by the operator on the upper part of the electrolytic cell with a pen before the busbar lifting operation. The operator is working at a high place during the process of drawing lines in the upper and lower electrolytic cells, and there are safety risks such as falling from a height, falling into the cell, and falling under the cell.
