る。"Structure of the invention" Means for solving the problems The present invention was devised to solve the problems in the conventional products as described above.
A furnace room is installed around the furnace body installed in the building,
The furnace chamber is provided with a ceiling opening to perform charging operations, and the ceiling opening is provided with an elevating hood to cover it, and the elevating hood is connected to the ceiling opening and the building. This is a dust collecting hood for a furnace room building, characterized in that it is provided with an elevating and lowering operation mechanism for elevating and lowering the hood to and from the dust collecting section.

る。Function: When loading scrap into the furnace, the elevating hood rises to collect dust from the building, and in this state, overhead cranes and the like can move smoothly without being obstructed by the elevating hood. When operating a furnace body such as an electric furnace, an elevating hood is lowered relative to the ceiling opening of the hearth chamber, thereby collecting dust within the hearth chamber.
Therefore, a single dust collection system can effectively collect dust from both the furnace room and the building.

る。Embodiment A concrete embodiment of the present invention shown in the attached drawings will be described. The furnace chamber 11 has a side wall door 12 for charging scrap, and a work opening furnace front door 1.
3. The provision of an opening 14 for oxygen blowing, a tap door 15, etc. is the same as the conventional one described above, and a ceiling opening 1 is provided in the upper part of the furnace chamber. However, an elevating hood 2 that covers the ceiling opening 1 is provided so that it can be raised and lowered between it and the building dust collection section by an elevating operation mechanism 3, and when the hood 2 is raised, Dust is collected from the building, and when the building is lowered, the opening 1 is closed to collect dust from the hearth chamber 11.
