Description

Technical Field

[0001] The utility model relates to the technical field of rain shield cover plates, in particular to a rain shield cover plate capable of preventing copper-clad hydrogen explosion. Background Art

[0002] Smelter converter workshop 6M 3 Copper bags are used to store high-temperature molten slag produced in the copper smelting process. Its main components are iron, silicon and other substances, and the temperature is between 1000-1200℃. The four copper bags filled with slag discharged from the converter are transported by a special train over a distance of 4km to the slag cooling area for crushing and slag selection. The empty copper bags are then transported back to the converter for recycling.

[0003] Since the copper ladle is designed to be open, if the empty copper ladle is transported from the slag to the converter in rainy and snowy weather, water will accumulate at the bottom of the copper ladle, and the height of the water at the bottom can reach up to 100mm. At this time, after the converter pours the high-temperature molten slag into the copper ladle, the high-temperature molten metal contacts the water, causing the water to vaporize rapidly, expand rapidly, and explode (the specific reaction is as follows: 2Fe (liquid) + 2H2O = FeO + 2H2 (gas), and then hydrogen explodes). After the explosion, the molten metal in the copper ladle splashes, causing damage to surrounding equipment and facilities, posing certain safety hazards, and requiring a lot of manual labor to clean up the splash residue. Secondly, the impact force generated by the explosion will cause cracks, perforations, and ruptures in the copper ladle wall, greatly reducing its service life. In order to solve the above problems, a rain shield cover that can prevent copper ladle hydrogen explosion is proposed. Summary of the invention

[0004] In order to solve the above problems, a rain shield cover capable of preventing copper-clad hydrogen explosion is proposed.

[0005] The specific scheme of the utility model is: a rain shield cover plate capable of preventing copper-clad hydrogen explosion, comprising: an end cover, the end cover is a circular plate structure, a skirt is provided on the circumference of the end cover, the skirt extends vertically downward, a connecting component is provided on the top of the end cover, the connecting component is used to connect with an external sling; the connecting component comprises:

[0006] Connecting columns, two or more of which are vertically arranged on the end cover, and the connecting columns are arranged side by side on the center line of the end cover;

[0007] A connecting crossbeam, which is disposed on the upper part of the connecting column and is fixedly connected to the connecting column, and the connecting crossbeam is parallel to the end cover;

[0008] Crossbeam baffles are provided at both ends of the connecting crossbeam, and the crossbeam baffles are used to prevent the sling from slipping off the connecting crossbeam.

[0009] Furthermore, the end cover is provided with crisscross reinforcing ribs, and the reinforcing ribs are fixed to the end cover by welding.

[0010] Furthermore, the diameter of the end cover is φ3000, unit: millimeter.
