The invention discloses a safety control device for a converter bell valve, which comprises a frame, a mounting base, a base, a first pulley, a bell valve, a second pulley, a third pulley, an operating platform, an electric control box, a control Terminal, servo motor, turntable, steel wire rope, steel column, compared with the prior art, the converter bell valve safety control device, when the converter flue gas needs to be discharged, open the remote control, so that the control terminal drives the servo motor Forward rotation, the servo motor drives the turntable to rotate forward, the first pulley, the second pulley and the third pulley synchronously rotate forward, so that the bell valve moves upward, the valve opens, and the smoke is discharged. When there is no need for smoke exhaust, the control terminal drives When the servo motor reverses, the wire rope is slack, the first pulley, the second pulley and the third pulley reverse, the bell valve moves downward, and the valve closes, effectively controlling the erosion of sulfur dioxide. The device is simple in structure, powerful in function, and easy to operate It is convenient and greatly improves the safety factor.
Description
technical field [0001] The invention relates to a safety control device, in particular to a safety control device for a rotary blowing furnace bell jar valve. Background technique [0002] Now the flue gas of the converter is mostly controlled by the bell valve. The bell valve for the converter is located in the waste heat boiler, which is far away from the converter operating room. Under normal circumstances, the computer is notified for remote control. At the same time, a control switch is set next to the bell valve. The on-site control switch of the cover valve is far away from the control room, and it is extremely inconvenient for personnel to operate during the exchange operation of the converter, especially in rainy and snowy weather and when the illumination at night is insufficient, safety accidents are prone to occur. In view of the above defects, it is necessary to design a safety control device for the bell jar valve of the converter blowing furnace. Contents of...
