Rhombic water jacket structure for fuming furnace and melting furnace

The utility model relates to a rhombic water jacket structure for a fuming furnace and a melting furnace, and belongs to the technical field of furnace body water jackets. The water jacket mainly comprises water jacket blocks which are in lap joint in sequence, the side portions of the water jacket blocks are inclined rhombus lap joint faces, every two adjacent water jacket blocks are in lap joint through the inclined rhombus lap joint faces, four fixing lug buckles are arranged on each water jacket block, and the water jacket blocks are fixedly connected with a workshop frame through the fixing lug buckles by means of screws. According to the utility model, the water cooling area of the splicing port is increased, so that high-temperature slag is cooled and solidified in the splicing port; moreover, the bevel lap joint can reduce the radial pressure of the molten pool vertical to the water jacket, so that the pressure and the speed of the high-temperature molten pool on the bevel lap joint surface are reduce
