Description

Technical Field

[0001] The utility model relates to the technical field of smelting, and in particular to a covering device for a molten iron tank. Background Art

[0002] At present, most domestic steel companies generally use open molten iron ladle to hold molten iron, and place the molten iron ladle on a molten iron ladle car and transport it from the blast furnace to the steelmaking operation area by diesel locomotive or car. However, the blast furnace in domestic steel companies is relatively far away from the steelmaking operation area. This section of the journey is an open-air working condition, especially the waiting time for iron under the blast furnace and iron addition in the steelmaking area is as long as 3-5 hours. During the uncovered transportation of the molten iron ladle, the molten iron is exposed, and the molten iron is in direct contact with the air. There is a large temperature difference between the molten iron and the molten iron ladle and the air, and heat exchange occurs continuously, causing a large amount of heat dissipation. In particular, the empty ladle after adding molten iron has a large heat dissipation area, which increases energy consumption and affects the life of the ladle lining, increasing production costs. In addition, the safety of transporting high-temperature molten iron is also poor. Therefore, the molten iron ladle needs to be covered.

[0003] After searching, the existing patent (publication number: CN219746313U) discloses a ladle covering device for a molten iron ladle car, including a car body, a placement groove is opened at the center of the upper end surface of the car body, the molten iron ladle body is installed in the placement groove, and the left and right sides of the placement groove are located at the front and rear ends of the car body and are fixed with fixed blocks. The fixed blocks on the left and right sides of the placement groove are respectively grouped, and a support frame is rotatably provided on the grouped fixed blocks. The bottom of the support frame is rotatably provided with an electric push rod away from the side of the placement groove. It can realize covering the top of the molten iron ladle body during transportation, improve its sealing, reduce the heat loss of the molten iron inside it, and at the same time, reduce the emission of harmful smoke and dust from the tank mouth and improve the air environment.

[0004] However, in the implementation of the relevant technology, it was found that the following problems exist: the above-mentioned device covers the molten iron tank by merging two split covers together. When the mouth of the molten iron tank needs to be opened for use later, the two covers need to be separated to the two sides of the molten iron tank. Finally, the two covers will be located on both sides of the molten iron tank respectively. However, the two covers will occupy the space on both sides of the molten iron tank respectively, causing the two covers to occupy more usable space on the entire vehicle body, which will cause obstacles to the subsequent process of pouring liquid from the molten iron tank, affecting the use of the molten iron tank.

The ring gear 83 is fixedly sleeved on the outer wall of the sealing cover 82. The gear 84 is rotatably connected to the lower surface of the cover plate 81, and the upper end of the gear 84 is fixedly connected to the output end of the second motor 85. The outer ring diameter of the ring gear 83 is larger than the outer ring diameter of the gear 84, and the gear 84 is meshed with the ring gear 83.
