Magnesium crystallizer

Abstract

The invention provides a magnesium crystallizer. The magnesium crystallizer comprises a tapered barrel body and an end cover part, wherein the tapered barrel body is provided with a large port and a small port; the end cover part is assembled at the small-port end of the tapered barrel body; the end cover part comprises a sealing plate and an escape plate, wherein the sealing plate is arranged on the inner side of the small port from the large port of the tapered barrel body; the escape plate is externally arranged on the outer side of the small port from the tapered barrel body; the sealing plate is further provided with a rod part extending to the outside of the small port of the tapered barrel body; a through hole for allowing the rod part to be inserted is formed in the center of the escape plate; the end cover part further comprises a fixed part which is fixed on the rod part and used for limiting the sealing plate and the escape plate to the two sides of the small port of the tapered barrel body; a gas gap is formed between the sealing plate and the inner wall of the tapered barrel body; and an escape hole is formed in the escape plate. The magnesium crystallizer is simple in structure, delicate in design, convenient for discharging and pressing of magnesium, capable of lowering the labor intensity of a worker and capable of improving the magnesium smelting production efficiency.

Description

technical field [0001] The invention relates to the field of magnesium smelting, in particular to a magnesium crystallizer used for magnesium smelting by Pidgeon method. Background technique [0002] Silicon thermal method is one of the main methods of smelting magnesium at present. Its process is as follows: calcining dolomite, the raw material for smelting magnesium, mixing the obtained calcined white with ferrosilicon and fluorite in proportion, finely grinding, pressing balls, and pressing well. Put the pellets into the reduction tank, then seal and vacuum the reduction tank and heat it to above 1200°C, so that ferrosilicon can be reduced to calcined white under vacuum and high temperature conditions to generate magnesium vapor. Under the action of the vacuum system, the generated magnesium vapor escapes to the mouth of the tank, and a cooling water jacket is installed near the mouth of the tank, where the magnesium vapor condenses to form crystalline magnesium. After t...

Problems solved by technology

However, while the existing potassium and sodium separator realizes the separation of potassium and sodium, it brings about complex structural design and difficulty in magnesium extraction, which not only increases the labor intensity of workers, but also reduces the production efficiency of the magnesium reduction cycle.
