Description of the embodiments
As shown in figure 1, the rotary type flue gas dust hood for the medium frequency electric furnace is composed of a dust hood 1, a flue gas pipeline, a multi-stage efficient combined dust remover and the like, wherein the flue gas pipeline comprises a movable flue gas pipeline 3 and a fixed flue gas pipeline 11. The front end of the movable flue gas pipeline 3 is vertically downwards bent, the dust hood 1 is arranged at the top of the upright 5 through the rotary upright and the plane bearing seat 4, and the upright base 6 is fixedly arranged on the working platform through bolts. In order to facilitate the stable rotation of the movable flue gas pipeline 3 around the upright post 5, a trapezoid support 9 is arranged between a dust hood of the movable flue gas pipeline 3 and the rotary upright post, and two movable rollers 10 are arranged at the bottom of the trapezoid support 9. The air inlet end of the fixed flue gas pipeline 11 is fixedly connected with the tail end of the movable flue gas pipeline 3 through a sealing locking joint 7.
