AI Technical Summary
When the converter is discharged, visual fatigue is caused by the hanging position of the safety warning sign and the long-term fixing, which may cause people to fail to notice the prohibited pass during the steel discharge process, which poses a major safety hazard.
Design a converter steel output safety protection warning system, including an angle monitoring device, a host, a PLC controller, acousto-optical alarm and a screen projector. When the converter emits a steel signal and the angle of the furnace reaches the set value, the PLC controller controls the acoustic and optical alarm to issue an acoustic alarm, and uses the screen projector to project the warning signs in the rear area of the furnace, prompting that passing through is prohibited.
Through sound warnings and screen projection warning slogans, safety hazards caused by visual fatigue or failure to notice the ban on travel are effectively prevented, and the safety of the working environment for steel out of the converter is significantly enhanced and the personal safety of the staff is ensured.

Description
Technical Field
[0001] The utility model relates to the technical field of safety protection for steel tapping from a converter, in particular to a safety protection warning system for steel tapping from a converter. Background Art
[0002] When the converter is tapping steel, a large amount of molten steel will be poured out, and the temperature is extremely high. Therefore, it is strictly forbidden for people to walk through this environment. In the prior art, although there is a safety warning sign "No walking during the steel tapping process" on the rear platform of the front furnace, people still often walk through the steel tapping process. There are two main reasons: 1. The safety warning sign is hung on the side close to the wall, and there may be people passing by who do not see it. 2. The safety warning sign is fixed for a long time, which causes visual and warning fatigue. People who need to walk with it may not know when they can pass, and it fails to serve as a warning reminder. Therefore, there is a huge safety hazard. In order to solve the above problems, a converter steel tapping safety protection warning system is proposed. Summary of the invention
[0003] In order to solve the above problems, a converter steel tapping safety protection warning system is provided.
[0004] The specific scheme of the utility model is: a safety protection warning system for steel tapping from a converter, comprising: a converter, characterized in that: an angle monitoring device is provided on the converter; a main engine is also provided on one side of the converter, and the main engine is used to send a steel tapping signal to the converter; the angle monitoring device and the main engine are both connected to the input end of the PLC controller, and the output end of the PLC controller is connected to an audible and visual alarm and a screen projector; the angle monitoring device is used to monitor the rotation angle of the converter; the PLC controller is used to receive the angle signal sent by the angle monitoring device and the steel tapping signal sent by the main engine, when the main engine of the converter sends a steel tapping signal, and the tilting angle detected by the angle monitoring device reaches the angle value set by the PLC controller, the PLC controller controls the audible and visual alarm to send a sound alarm, and the PLC controller controls the screen projector to project a warning slogan on the rear area of the converter.
[0005] Furthermore, the angle monitoring device is an angle sensor.
[0006] Furthermore, the tilting angle value set by the PLC controller is -45 degrees.
[0007] Furthermore, the projector projects a warning slogan with red letters on a yellow background in the area behind the converter: No passing; the sound and light alarm emits a sound alarm with the content: The converter is producing steel, and passing through the area behind the converter is strictly prohibited.
[0008] The operating method of the utility model is as follows: when the converter is at the end of blowing and is ready to tap steel, the main machine sends out a "steel tapping signal" and when the tilting angle of the converter reaches -45 degrees, the angle sensor transmits the tilting angle signal to the PLC controller. When the above two conditions are met, the control signal of the PLC controller is triggered, and the signal is transmitted to the screen projector and the voice-controlled alarm through the signal line as a "control signal" for the start of the screen projection and the voice-controlled alarm. When the screen projector is turned on, the font "No Passing" is automatically projected onto the ground, and the voice-controlled alarm device sends out a sound alarm "The converter is tapping steel, and the area behind the furnace is strictly prohibited from passing through", indicating that the platform behind the furnace is not passable at this time; when the tapping is completed and the converter is lifted to -45 degrees, the PLC control signal disappears, the screen projector and the voice-controlled alarm device are automatically turned off, and the screen projection and alarm sound of "No Passing" on the ground of the platform behind the furnace disappear, indicating that normal passage is allowed.
[0009] The utility model has the following beneficial effects: simple structure and convenient control; through sound warnings and screen-projected warning slogans, it effectively prevents people from walking through the area behind the converter when tapping steel due to difficulties in seeing, greatly enhancing the safety of the converter steel tapping working environment and ensuring the life safety of the staff.
