Sectional type electrolytic tank for recycling iron and steel slag

The invention relates to the field of iron and steel slag, in particular to a sectional type electrolytic tank for recycling iron and steel slag. The technical problem to be solved is to provide a sectional type electrolytic tank for recycling iron and steel slag. According to the technical scheme, the sectional type electrolytic tank for recycling the iron and steel slag comprises a first supporting table, a first supporting frame, a circulating assembly, a scraping assembly, a collecting assembly and the like; the first supporting table is fixedly connected with the circulating assembly; and the first supporting frame is arranged on the outer side of the first supporting table. When the sectional type electrolytic tank is used, the treated iron slag is automatically electrolyzed, so that an iron element is enriched on a negative plate, and the function of recycling the iron slag is achieved; iron with different physical properties at the middle-upper part and the middle-lower part of the negative plate is a
