Description

Technical Field

[0001] The invention relates to the technical field of high temperature furnace hauling, and in particular to a heavy automatic hauling device for a high temperature furnace. Background Art

[0002] A high temperature furnace is a furnace that can reach very high temperatures and is used for processes such as heating, smelting, heat treatment or chemical reactions. High temperature furnaces are widely used in industries such as metallurgy, materials science, and chemical engineering, especially when materials such as metals, ceramics, glass, ores, etc. need to be heated and processed.

[0003] Heavy-duty automatic hauling devices for high-temperature furnaces are usually used in high-temperature environments in industrial production, especially in the fields of metallurgy, chemical industry, and electric power, when transporting materials in or around high-temperature furnaces. The device needs to have the characteristics of high temperature resistance, strong load-bearing capacity, high stability, and automatic control. Heavy-duty automatic hauling devices for high-temperature furnaces (such as slag transport vehicles, automatic hauling systems, etc.) are widely used in high-temperature smelting processes such as steel smelters. The main task is to automatically and efficiently transport slag, molten steel or other high-temperature materials from the smelting furnace to the designated processing, storage or discharge area. The design of such devices usually takes into account special requirements such as high temperature, heavy load, and complex working environment. With the advancement of technology, modern heavy-duty automatic hauling devices for high-temperature furnaces can integrate multiple functions to further improve their efficiency, precision, and safety.

[0004] During the metallurgical process, high-temperature slag is produced, and the slag in the high-temperature furnace needs to be transferred and dumped in a timely manner. Since the existing heavy-duty automatic hauling device for high-temperature furnaces is inconvenient to cover the furnace mouth of the high-temperature furnace filled with liquid slag when hauling the high-temperature furnace, the slag is easy to splash out during the hauling process, or other objects fall into the high-temperature liquid slag during the hauling process, resulting in the risk of high-temperature liquid slag splashing, which brings safety risks to equipment operators. High-temperature liquid slag is not only easy to cause burns, but may also cause serious accidents such as fire and explosion.

[0005] In summary, the prior art lacks a technology for covering the furnace mouth when hauling a high-temperature furnace filled with liquid slag. Summary of the invention

At the same time, exhaust holes are opened on the splash cover to prevent gas accumulation or excessive pressure in the furnace, which can effectively release the gas in the furnace and avoid safety problems caused by gas expansion; 2. By setting up the slag scraper, the transmission mechanism can retract the splash cover and drive the slag scraper to move back and forth quickly to scrape off the slag attached to the splash cover, which greatly reduces the manual cleaning work, improves the production efficiency, and ensures that the splash cover always maintains a good working condition. At the same time, by setting up the hole cleaning sleeve, the hole cleaning sleeve can clean the inner wall of the exhaust port on the splash cover while the splash cover is retracted, avoiding gas discharge obstruction, ensuring the stability of the atmosphere in the furnace, helping to reduce equipment failure rate and maintenance costs, and extending the service life of the equipment; 3. By setting up guardrails and movable fences, when a high-temperature furnace containing high-temperature liquid slag is towed, it can be blocked outside the high-temperature furnace, which can isolate the high-temperature area and prevent surrounding workers from approaching or misoperating, thereby reducing the risk of high-temperature burns and other accidents.
