Description

Technical Field

[0001] The utility model relates to the technical field of magnesium smelting equipment, in particular to a water jacket structure of a reduction tank. Background Art

[0002] The water jacket structure of the reduction tank is composed of a cooling water jacket, which is exposed outside the furnace wall and is cooled by circulating water.

[0003] In existing magnesium reduction tanks, an alkali metal trap and a magnesium crystallizer are installed at the tank mouth, and then a sealing cover is directly closed. During the reduction process, uncrystallized magnesium vapor will directly pass through the magnesium crystallizer and diffuse, and then condense on the outside of the crystallizer or the inner wall of the sealing cover. This makes it difficult to remove the crystallized magnesium and requires frequent cleaning of the outer wall of the crystallizer and the reduction tank mouth, affecting overall production efficiency. Chinese patent CN215481173U discloses a multifunctional water-jacketed sealing cover with a cooling device for metal magnesium smelting. The multifunctional water-jacketed sealing cover is installed at the tank mouth of the magnesium reduction tank, and the magnesium crystallizer is installed inside the tank mouth of the magnesium reduction tank. The cooling water jacket is installed on the outer wall of the magnesium reduction tank. The multifunctional water-jacketed sealing cover includes: an outer fixed cover and an inner sealing cover assembly. The outer fixed cover is an annular sheet structure and is installed at the tank mouth of the magnesium reduction tank. The inner sealing cover assembly is installed on the inner circle of the outer fixed cover.

[0004] The cooling water jacket in this device can cool the mouth of the magnesium reduction tank, allowing magnesium to crystallize quickly in the magnesium crystallizer. However, since there is no water circulation structure in the cooling water jacket, the temperature of the water in the cooling water jacket will become higher and higher, resulting in the cooling effect of the cooling water jacket on the mouth of the magnesium reduction tank becoming increasingly poor, causing the magnesium crystallization speed in the magnesium crystallizer to become increasingly slow, affecting the progress of the magnesium metal smelting work.
