Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic baking anode bottom edge cleaning, in particular to an online automatic cleaning device for the electrolytic baking anode bottom. Background Art

[0002] The anode carbon block is made of petroleum coke of different particle sizes and liquid asphalt, which are heated and mixed into a paste, put into a mold, and vibrated on a vibrating table and pressed by a heavy hammer to form a raw anode carbon block; after forming, the anode carbon block is a rectangular parallelepiped, and the chamfers on the four surfaces are realized by the mold. The upper surface is provided with a formed carbon bowl, which is used for casting when the anode carbon block is assembled with the aluminum guide rod. The upper surface carbon bowl and chamfers are pressed by a heavy hammer, and then the raw anode carbon block is loaded into a roasting furnace, and carbon fillings are added to the four sides. After high-temperature roasting, it becomes an anode carbon block for electrolysis.

[0003] At present, the domestic anode carbon block roasting adopts the method of vertically loading the anode carbon blocks. The raw anode carbon blocks are vertically placed in the roasting furnace and heated at 1100 degrees under the condition of air isolation to convert the binder into carbon in the process of preventing the carbon blocks from deforming and transferring heat during the roasting process. Carbon filling is added on all sides. During the roasting process, the asphalt binder of the anode carbon blocks cokes and bonds the carbon filling. There are many granular carbon particles attached to the surface of the anode carbon blocks after they are taken out of the furnace. The surface adhesions need to be cleaned before they can be used in electrolytic aluminum production to avoid slagging in the electrolytic cell during use, thereby increasing the cost of the enterprise.

[0004] There are two main methods for cleaning traditional electrolytic roasted anodes. The first one is mainly done manually, which is inefficient, and different employees have different operating levels. The cleaning of the electrolytic roasted anodes is uneven, and the cleaning effect is difficult to guarantee, which seriously affects the production efficiency of the anode carbon blocks; and because the cleaning environment is full of smoke, it pollutes the environment and causes harm to the human body; the second is to use intelligent control robots for cleaning. In this cleaning method, the cleaning means of the equipment are limited, and often only a single cleaning means. After the electrolytic roasted anode is automatically cleaned by the equipment, there will be more or less residual substances on the bottom edges and arc surfaces of the electrolytic roasted anode that are not easy to clean, and manual processing is required later. The cleaning effect of the electrolytic roasted anode cannot achieve the expected effect. Utility Model Content
