Abstract

The invention discloses a safety control device of a blowing converter bell type valve. The device comprises a rack, a mounting seat, a pedestal, a first pulley, a bell type valve, a second pulley, a third pulley, an operating platform, an electrical control box, a control terminal, a servo motor, a rotary disc, a steel wire rope and a steel column. Compared with the prior art, the safety control device of the blowing converter bell type valve has the advantages that when smoke of the blowing converter is required to be exhausted, a remote controller is turned on, the servo motor is driven by the control terminal to rotate forwardly, the rotary disc is driven by the servo motor to rotate forwardly, the first pulley, the second pulley and the third pulley rotate synchronously and forwardly, the bell type valve moves upwards, and the valve is opened to exhaust the smoke; when the smoke is not required to be exhausted, the servo motor is driven by the control terminal to rotate reversely, the steel wire rope is loosened, the first pulley, the second pulley and the third pulley rotate reversely, the bell type valve moves downwards, the valve is closed, and erosion of sulfur dioxide is effectively controlled. The device has the advantages of simple structure, powerful function, convenience in operation and capability of greatly improving the safety coefficient.

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...
