Synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace

Abstract

The invention relates to a synchronizer for a bidirectional-movement smoke exhaust pipe of a electric furnace, which comprises a smoke exhaust pipe, a servo speed reducer, a revolving shaft, a wheel, a guide rail, an electric screw rod, a flexible bracket and a compensating sliding block; wherein the smoke exhaust pipe comprises a flexible-section smoke exhaust pipe and a revolving-section smoke exhaust pipe which are mutually connected by the flexible bracket, the electric screw rod pushes the flexible-section smoke exhaust pipe to move along the flexible bracket, the servo speed reducer drives the wheel on a frame to linearly move along the guide rail so as to drive the revolving-section smoke exhaust pipe to swing by taking the revolving shaft as a center, and the compensating sliding block is arranged between the revolving-section smoke exhaust pipe and the frame. In the invention, the synchronous movement between the smoke exhaust pipe and four holes of an electric furnace cover along the guide rail and the staggered movement between the smoke exhaust pipe and the four holes of the electric furnace cover along the flexible bracket can be both realized; more smoke of an electric furnace can be discharged under the condition of not influencing the opening of the furnace cover, and the suction of cold air is reduced, thereby improving the smoke gathering ratio.

Description

technical field [0001] The invention relates to a smoke exhaust synchronous device, in particular to a synchronous device for two-way moving smoke exhaust pipes of an electric furnace. Background technique [0002] The flue gas discharged from the steelmaking electric furnace contains a large amount of high-temperature waste heat. The temperature of the waste heat flue gas fluctuates violently and contains a large amount of dust. Due to the needs of energy saving and emission reduction, the utilization of this high-temperature waste heat has gradually become mature and popular. At present, the smoke exhaust pipe of the four-hole interface of the electric furnace cover can only move in one direction. The movable smoke exhaust pipe is fixed on the moving frame, and the oil cylinder pushes the moving frame to move along the guide rails to realize the movement of opening the four holes of the electric furnace cover. . However, the movable smoke exhaust pipe cannot follow the mo...

AI Technical Summary

Problems solved by technology

However, the movable smoke exhaust pipe cannot follow the movement in the tilting direction of the four holes of the electric furnace cover, so that the movable smoke exhaust pipe is directly exposed to the air and mixed with a large amount of cold wind, which affects the smoke exhaust effect of the smoke exhaust pipe on the electric furnace flue gas, and the electric furnace flue gas is large Spilled into the workshop, affecting the environment and the health of workers. In addition, when the waste heat recovery device is connected behind the exhaust pipe, due to the large amount of cold air mixed in, the amount of waste heat recovery is insufficient and the heat is not recovered effectively.
