Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical industrial production equipment, in particular to a water - inlet prevention structure of a capping device for a molten - iron car. Background Art

[0002] A molten - iron car is a transportation device used in steel enterprises to transport molten iron from a blast furnace to a steel - making plant for steel - making or to a foundry for casting iron blocks. Most steel enterprises generally use an open - top molten - iron ladle to hold molten iron, and then a diesel locomotive is used to tow a formation of multiple molten - iron cars carrying molten - iron ladles to transport the molten iron from the blast furnace to the steel - making operation area or the casting operation area. In order to avoid heat loss of the molten iron during transportation, some steel enterprises have started to design a capping device for the molten - iron ladle.

[0003] The capping device usually consists of two cover plates. The two cover plates move synchronously to achieve the opening and closing actions. However, there are inevitably gaps at the combination of the two cover plates. In case of rain, a small amount of rainwater still flows into the molten - iron ladle through the gaps, resulting in a decrease in the temperature of the internal molten iron. Summary of the Utility Model

[0004] Based on the above problems, the purpose of the utility model is to provide a water - inlet prevention structure of a capping device for a molten - iron car, which can effectively reduce the rainwater from entering the molten - iron ladle through the gaps of the capping device and improve the water - blocking effect.

[0005] To achieve the above - mentioned purpose, the utility model adopts the following technical solutions:

[0006] A water - inlet prevention structure of a capping device for a molten - iron car, wherein the capping device includes a first cover plate and a second cover plate. When the capping device is closed, there is a splicing gap between the first cover plate and the second cover plate. A first water - blocking strip is arranged on the top surface of the first cover plate along the splicing gap, and a second water - blocking strip is arranged on the top surface of the second cover plate along the splicing gap. When the capping device is closed, the first water - blocking strip and the second water - blocking strip are arranged oppositely, and both the first water - blocking strip and the second water - blocking strip are higher than the splicing gap. An elastic rubber strip is arranged on the surface of the first water - blocking strip facing the second water - blocking strip, and the elastic rubber strip is clamped by the first water - blocking strip and the second water - blocking strip to seal the splicing gap.

[0007] As an optional solution, the natural thickness of the elastic rubber strip is greater than the width of the splicing gap. When the capping device is closed, the elastic rubber strip is clamped and compressed by the first water - blocking strip and the second water - blocking strip.

[0008] As an optional solution, diversion grooves are respectively arranged on the top surface of the first cover plate and on the side of the first water - blocking strip away from the splicing gap, and on the top surface of the second cover plate and on the side of the second water - blocking strip away from the splicing gap.

[0009] As an optional solution, the first water retaining bar and the second water retaining bar are formed by welding stainless steel angle steels to the first cover plate or the second cover plate respectively.

[0010] As an optional solution, the elastic rubber strip extends downward from the top of the first water retaining strip and extends into the joint gap by 5 cm to 10 cm.

[0011] As an optional solution, a baffle for covering the joint gap is provided on the side surface of the first cover plate or the side surface of the second cover plate.

[0012] The beneficial effects of the utility model are as follows: the water ingress prevention structure of the molten iron car covering device transforms the splicing gaps of the original molten iron car, and by adding a first water retaining bar, a second water retaining bar and an elastic rubber strip, rainwater is prevented from entering the molten iron tank from the splicing gaps as much as possible. The water-blocking effect is obvious, and the opening and closing actions are not affected, thus meeting the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
