<p>An aluminum electrolytic tank anode carbon block of an irregularly-shaped structure with an exhaust passage and a preparation method thereof. The edge part of a top surface is provided with a chamfer. A row or two rows of carbon bowls are uniformly distributed on the top surface. Each row of the carbon bowls are longitudinally arranged along the anode carbon block and consist of 3 to 5 carbon bowls. A groove is formed between the carbon bowls, the bottom of the anode carbon block is provided with a trench, and the bottom of the groove is provided with a through hole which is communicated with the trench at the bottom of the anode carbon block. The preparation method comprises: preparing the carbon block by using a vibration mould or pressing mould with corresponding bumps by a vibration molding method or a compression molding method; and roasting and then cutting out the trench. The aluminum electrolytic tank anode carbon block of the irregularly-shaped structure with the exhaust passage of the present invention has the characteristics of a simple and convenient preparation process, high working efficiency and the like. Besides, it is obtained through testing that the tank voltage can be reduced by using the anode carbon block, the gas produced by an anode is smoothly and uniformly discharged, and the influence of gas escape on fluctuation of cathode aluminum liquid is obviously reduced.</p> |
