Description

Technical Field

[0001] The utility model relates to the field of non-ferrous metallurgy, in particular to a sealing cover for a water-cooled jacket of a magnesium reduction tank. Background Art

[0002] In the current prior art, the magnesium reduction tank assembly mainly consists of a reduction tank body, a crystallizer, a fire baffle, a water-cooled jacket and a sealing cover, etc. The sealing cover is the sealing cover at the outer opening of the water-cooled jacket and is composed of a hanging rod and an end cover, mainly playing a sealing role to keep the temperature stable at the crystallizer part. The disadvantages of this water-cooled jacket sealing cover are: the sealing effect is not good, there is an air leakage condition, the temperature at the crystallizer part cannot be kept stable, resulting in poor crystallization effect of magnesium vapor. Summary of the Invention

[0003] In order to overcome the above-mentioned disadvantages of the prior art, the purpose of the utility model is to provide a sealing cover with good sealing effect, keeping the temperature stable at the crystallizer part and achieving the purpose of improving the crystallization effect of magnesium vapor.

[0004] The sealing cover of the utility model includes a sealing cover body, a hanging part, a heat-resistant sealing silica gel ring, a rubber ring groove and an air hole. During normal production, the sealing cover is hung through the hanging part, and the hot air flow enters the rubber ring groove through the air hole. Under the action of the hot air flow pressure, the heat-resistant sealing silica gel ring is extruded outward from the rubber ring groove. The sealing cover has been restricted in position at the water-cooled jacket opening by the hanging part and cannot move outward, playing a good sealing effect on the reduction tank opening.

[0005] By adopting the above technical solution, under the action of the new sealing cover, the reduction tank assembly is further sealed through screw fixing and limiting and air pressure extrusion, avoiding the existence of air leakage condition, keeping the temperature stable at the crystallizer part and improving the crystallization effect of magnesium vapor.

The specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0010] Figure 1As shown in the figure, it is a reduction tank assembly, which is composed of a reduction tank body 7 and a water-cooling jacket body 3; the water-cooling jacket body 3 is mainly composed of a water-cooling jacket, water inlet and outlet 1, 2, a vacuum pipe orifice 6, a crystallizer 5, a sealing cover 4, etc.

[0011] Figure 2 As shown in the figure, it is a cross-sectional schematic diagram of the sealing cover 4. The sealing cover includes a sealing cover body, a hanging part 8, a rubber ring groove 9, an air hole 10, and a screw 11; the hanging part 8 is in a right-angled shape, and there is an internal thread hole 12 on the hanging part 8 for limiting the sealing cover.

[0012] Figure 3 As shown in the figure, it is a plan schematic diagram of the sealing cover 4, including the sealing cover body, the hanging part 8, the rubber ring groove 9, the air hole 10, and the internal thread hole 12 of the screw 11; on the inner side of the rubber ring groove 9, air holes 10 are evenly distributed, and the inner ends of the air holes 10 lead to the bottom of the rubber ring groove 9.

[0013] After the reduction tank is filled with materials, the crystallizer is placed in it, the sealing cover 4 is hung, and the screw 11 is turned to tighten the sealing cover 4. Under the combined action of the heat-resistant sealing silica gel ring and the air pressure in the rubber ring groove 9, the opening of the reduction tank is well sealed, avoiding air leakage, maintaining the stability of the temperature at the crystallizer part, and improving the crystallization effect of magnesium vapor.
