Problems solved by technology
[0003] The split-type furnace cover of the existing rotatable metallurgical furnace is large in size, occupies a large space, and is easy to accumulate dust. The furnace cover is cooled by a water jacket. The cooling water in the water jacket requires special cooling measures and cannot recover heat. Therefore, the existing furnace cover The service life is short, and the process maintenance and adjustment are inconvenient

The invention discloses a split-type furnace hood of a rotatable metallurgical furnace and the rotatable metallurgical furnace provided with the split-type furnace hood. The split-type furnace hood of the rotatable metallurgical furnace comprises a first hood body, a second hood body and a baffle, wherein the first hood body is of a straight tube shape, the lower end face of the first hood body is of an arc shape, and the upper end of the first hood body is provided with a main smoke outlet; the second hood body is of an arc shape, the upper end of the second hood body is connected with the side wall of the lower end of the first hood body, the lower edge of the second hood body and the lower end face of the first hood body are located in the same circumference, and the second hood body is provided with an emergency smoke outlet; the baffle is arranged at the joint between the first hood body and the second hood body, and the upper end of the baffle is connected with the first hood body or the second hood body in a swinging mode. The split-type furnace hood of the rotatable metallurgical furnace has the advantages of being small in size, small in occupied space, not prone to soot formation, good in sealing performance, convenient to overhaul and adjust technically and the like.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to a split furnace cover of a rotatable metallurgical furnace and a rotatable metallurgical furnace with the same. Background technique [0002] Rotatable metallurgical furnaces, such as rotatable metallurgical furnaces, are commonly used equipment in the metallurgical industry. The rotatable metallurgical furnace is widely used in the smelting of non-ferrous metals. During the smelting process, in order to effectively recover the waste heat of the rotatable metallurgical furnace, a waste heat boiler is installed above the smoke outlet of the rotatable metallurgical furnace. The waste heat boiler passes through the furnace cover and the rotatable The metallurgical furnace is connected so that the high-temperature flue gas enters the waste heat boiler from the rotatable metallurgical furnace, so that the heat in the high-temperature flue gas can be recovered through heat exchange.
