Description

Technical Field

[0001] The utility model relates to the technical field of nonferrous metal magnesium smelting, in particular to a novel fire baffle device for a vertical reduction furnace crystallizer. Background Art

[0002] The pain point of magnesium discharge is the sealing problem of the center tube and the bottom of the reduction tank. If the sealing is not good, the reduction slag will leak into the crystallizer. When the pellets burst, the dust will enter the crystallizer through the magnesium vapor hole in the center tube. At present, the large mouth of the magnesium discharge crystallizer is installed downward, and there are also cases where the clamped tank crystallizer cannot be taken out. Most of the clamped tank positions are at the bell mouth of the reduction tank, but the number is small. The furnace front worker opens the cover of the reduction tank and uses the gravity of the material to load / discharge the ball material. The material box is transported to the top of the reduction tank by a crane. Only manual assistance is needed to straighten the material box so that the discharge port of the material box is aligned with the tank mouth of the reduction tank. The discharge port of the material box is opened, and the material in the material box falls directly into the reduction tank due to gravity. After being installed according to regulations, the fire baffle, magnesium crystallization barrel, and potassium-sodium crystallizer are placed in the water jacket in turn, and the vacuum valve is opened to complete the loading; after a reduction cycle, the magnesium in the ball material is reduced to form crystalline magnesium. The furnace front worker opens the tank cover, takes out the magnesium crystallization barrel, and removes the slag for external processing.

[0003] The disadvantages of magnesium production in vertical tanks are long debugging time and high production cost. When magnesium vapor rises with the airflow and encounters cold, it will condense into small droplets. If the temperature continues to drop with the increase in height and reaches below the freezing point of magnesium, the droplets will condense into magnesium particles. During its upward transportation, it will absorb small particles or droplets around it and grow until its weight can no longer be carried by the rising airflow, then it will fall. When it falls to a higher temperature zone, its surface will melt into liquid and also absorb small droplets around it. At this time, if it encounters a strong rising airflow and is lifted again, its surface will condense into particles again. This process is repeated like a snowball, and its volume becomes larger and larger until its weight is greater than the buoyancy of magnesium vapor, and then it falls. The solid-liquid mixture that has not melted into liquid at the small opening of the vertical tank blocks the slag outlet. Therefore, it has become an urgent problem to be solved to improve and improve the above-mentioned problems. Summary of the invention
