Aluminum cell with pre-baked anode

Abstract

The invention relates to an aluminum cell with a prebaked anode. The aluminum cell with the prebaked anode comprises a pot shell main body, a lining, a machine frame, stand columns, a sealing cover plate, a pair of anode carbon block sets, a pair of anode lifting devices, a pair of anode buses and a crust-breaking and feeding system, wherein the interior of the pot shell main body is hollow, and an opening is formed in the upper end of the pot shell main body; the lining is arranged in the pot shell main body; the machine frame is vertically arranged on the pot shell main body through the stand columns; the sealing cover plate covers the opening; the pair of anode carbon block sets are arranged at the opening of the pot shell main body in parallel; the pair of anode lifting devices are arranged at the top end of the machine frame in parallel; the output ends of the anode lifting devices face the pot shell main body; one ends of the pair of anode buses are connected to the output ends of the pair of anode lifting devices correspondingly; the other ends of the anode buses are connected to the pair of anode carbon block sets correspondingly; the crust-breaking and feeding system is arranged at the top end of the machine frame; the feeding end of the crust-breaking and feeding system extends into the pot shell main body; and the crust-breaking and feeding system is located betweenthe pair of anode lifting devices. According to the aluminum cell, the current efficiency can be improved, the electrochemical reaction efficiency can be improved, the heat efficiency of the electrolytic cell can be improved, and the consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of electrolytic aluminum, in particular to a prebaked anode aluminum electrolytic cell. Background technique [0002] After more than 60 years of development, the electrolytic aluminum industry in New China has made great achievements in all aspects. In 2016, the output of electrolytic aluminum in China increased by 10.6% year-on-year to approximately 31.11 million tons. The annual production capacity of electrolytic aluminum in China has reached about 37.2 million tons. The electrolytic aluminum market in my country is currently in a situation of overcapacity. The annual idle electrolytic aluminum production capacity is about 1 million tons, and the idle assets exceed about 10 billion yuan, which has caused a huge increase in social wealth. waste. The new capacity of electrolytic aluminum is mainly concentrated in Shandong, Xinjiang and Inner Mongolia. Since 2016, the price of aluminum has been around 13,5...
