Linkage air extraction device of smelting furnace

Abstract

The invention relates to a linkage air extraction device of a smelting furnace. The linkage air extraction device comprises the smelting furnace, an outer cover surrounding the smelting furnace, a movable door mounted on one side of the outer cover, guide rails mounted on the outer cover, a smoke exhaust fan located at the top of the outer cover, limiting devices mounted on the guide rails and a controller connected with the movable door and the smoke exhaust fan. The movable door moves up and down along the guide rails. According to the linkage air extraction device of the smelting furnace, through the mutual linkage function of the movable door and the smoke exhaust fan, wind power of the smoke exhaust fan is reduced when the movable door descends, the smoke exhaust capacity is reduced and even stops, heat in the outer cover is preserved, heat waste is avoided, and energy is saved; and when the movable door ascends, the wind power of the smoke exhaust fan is increased, the smoke exhaust capacity is increased, heat is dissipated, the operation environment of workers is improved, and work is facilitated.

Description

technical field [0001] The invention relates to the technical field of aluminum profile manufacturing equipment, in particular to a linkage exhaust device for a smelting furnace. Background technique [0002] The smelting furnace for manufacturing aluminum profiles is used to smelt metal ingots. During the smelting process, due to production needs, the smelting furnace needs to be dusted, and forklifts will also enter and exit the smelting furnace from time to time. In order to facilitate forklifts entering and leaving the smelting furnace, generally The door of the exhaust device of the smelting furnace is set very high, the heat inside the smelting furnace is continuously emitted, especially when the ash is picked up, the heat is emitted very quickly, and the emitted heat affects the surrounding environment, which is in line with the current environmental protection On the other hand, because the heat inside the smelting furnace is obtained by burning energy, the distribut...

[0002] The smelting furnace for manufacturing aluminum profiles is used to smelt metal ingots. During the smelting process, due to production needs, the smelting furnace needs to be dusted, and forklifts will also enter and exit the smelting furnace from time to time. In order to facilitate forklifts entering and leaving the smelting furnace, generally The door of the exhaust device of the smelting furnace is set very high, the heat inside the smelting furnace is continuously emitted, especially when the ash is picked up, the heat is emitted very quickly, and the emitted heat affects the surrounding environment, which is in line with the current environmental protection On the other hand, since the heat inside the smelting furnace is obtained by burning energy, the dissipation of heat will undoubtedly increase the combustion of fuel, which is not conducive to saving energy.
