Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum electrolysis pole-changing technology, in particular to an aluminum electrolysis pole-changing dust collecting device. Background Art

[0002] In the process of electrolytic aluminum production, the main function of the anode is to inject aluminum oxide into the electrolyte for oxidation reaction. As the production volume increases, the anode blocks used in the electrolytic cell are constantly consumed, oxidized and mechanically worn. Therefore, after a certain number of days of use, the residual anode needs to be replaced and a new anode needs to be installed. During the anode replacement process, due to the consumption and oxidation of the anode, more residues will be generated, and more dust will be generated during cleaning, which will cause harm to the health of the workers. Therefore, it is necessary to clean the anode blocks during cleaning.

[0003] Existing aluminum electrolysis pole-changing dust collection devices, such as a dust collecting hood for aluminum electrolysis pole-changing dust collection disclosed in application number CN202121105903.8, synchronously move the dust collecting hood and the lifting device, and adopt a mechanically openable and closable flap to ensure that the dust collecting hood reaches the closest distance to the anode carbon block, thereby ensuring the dust collection effect and improving the dust collection efficiency.

[0004] However, in actual use, the dust collecting device in the prior art needs to be pre-installed with the aluminum electrolysis equipment and cannot be moved. For large-scale aluminum electrolysis production, the construction cost is high, and it is inconvenient to clean it. The dust collecting hood still needs to be opened manually for shoveling, and dust will still be generated during operation. In particular, when replacing, it is necessary to use an overhead crane to knock on the crust around the anode to be replaced. The closed dust collecting hood is not convenient for the construction of the overhead crane. For this reason, we propose an aluminum electrolysis anode replacement dust collecting device to solve the above problems. Utility Model Content
