Background

In the prior art in the field of magnesium smelting by a silicothermic process, the main method for producing metal magnesium mainly adopts a horizontal reduction tank reduction method, the horizontal reduction tank is horizontally arranged to be a main structure, the horizontal reduction furnace has low space utilization rate and low yield, the auxiliary slag drawing equipment is not mature enough, the mechanical operation is difficult to be carried out in a high-temperature state, the labor intensity of workers is high, the operation environment is severe, the charging and discharging time is long, the charging and slag drawing are completed by the operation of the workers, the work is heavy, the high-temperature radiant heat and a large amount of smoke dust generated in the slag drawing process can damage the health of the human body, the loss rate of the workers in front of the furnace is high, the personnel cost is increased, and the unstable product. In the conventional equipment, a reduction tank is directly and vertically arranged in a reduction furnace, the gravity of the reduction tank is supported only by the bottom of the reduction furnace, as shown in figure 1, in the magnesium metal smelting process, austenitic heat-resistant stainless steel is adopted: the manufacturing cost of the reduction tank made of 35Cr24Ni7SiN is very high, because of the special structure of the vertical reduction furnace, the reduction tank is vertically placed in the reduction furnace, the gravity of the reduction tank is supported only by the bottom of the reduction furnace, and the reduction tank is easy to generate tensile plastic deformation under the action of high temperature, gravity and low vacuum, so that the damage of the reduction tank is caused, the consumption of the reduction tank of metal magnesium is increased, and the production and manufacturing cost is increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses an elastic support device of vertical reduction furnace reduction jar has reinforceed the supporting role of reduction jar, improves the life of reduction jar, ensures magnesium metal reduction technology's continuity and stability, reduction in production cost.

The technical scheme of the utility model is that:

the elastic supporting device is arranged on two sides of the upper part of the reduction tank, the supporting effect of the reduction tank is enhanced through the elastic supporting device of the reduction tank, the service life of the reduction tank is prolonged, the continuity and stability of a metal magnesium reduction process are ensured, and the production cost is reduced.

The elastic supporting device comprises spring wrapping half pipes arranged on two sides of the upper end of the reduction pot, springs are arranged in the spring wrapping half pipes, pressing blocks are arranged at the upper ends of the springs, the lower ends of the springs are arranged on brackets, the brackets comprise first brackets and second brackets, and I-shaped beams are arranged on the outer sides of the brackets.

And a spring positioning core rod is arranged on the inner side of the spring, so that the spring can stretch along the spring positioning core rod.

The elastic supporting device is arranged on the outer side wall of the water jacket at the top of the reduction tank.

Wherein, first bracket and second bracket are used for controlling the balance, and the I-shaped roof beam is used for the supporting leg, plays stabilizing effect, and the spring of package is half managed and is used for positioning spring, and positioning spring inside is equipped with spring location plug, and the effect of playing is fixed spring, and elastic support is used for supporting the water jacket, alleviates the bearing capacity of furnace roof.

The utility model has the advantages that: the support function of the reduction tank is strengthened, the service life of the reduction tank is prolonged, the continuity and the stability of the magnesium metal reduction process are ensured, and the production cost is reduced.

The present invention will be further explained with reference to the drawings and examples.
