Description
Technical field
The utility model belongs to steelmaking ingredient lime stone handling system automation field.
Background technology
In a control system, when equipment runs and occurs abnormal, interlocked control opens automatic protection functions, closes down relevant device rapidly, to ensure the production safety of equipment.
In generation Taiyuan Iron and Steel Co. shaft furnace source material delivery system design year, is in the sixties, it adopts Control, in system operation, there is wiring complexity, fault is many, equipment protecting equipment is incomplete problem, occur now and then because of repair quality problem or relay contact bad contact generation breakdown of equipment; Breakdown Maintenance personnel will search according to drawing pointwise each time, and the time is at least at 2-3 days.Along with time lapse and technical development, be not suitable with current need of production, according to statistics, the annual repair time therefore occurred is about 120 hours (zero light maintenance), by 25T capacity calculation per hour, be only that this maintenance will carry 3000 tons, limestone less, also do not include fault and reprocess the loss caused.
Summary of the invention
The utility model provide can fast failure judgement position and trouble-shooting fast speed steelmaking ingredient limestone conveying autonomous cruise speed system.
Technical scheme of the present invention: steelmaking ingredient limestone conveying autonomous cruise speed system, comprise 3 band conveyors, every bar band conveyor is equipped with speed measuring device, it is characterized in that being provided with hopper between Article 1 band conveyor and Article 2 band conveyor, hopper is provided with Anti-blockage shakeout machine, blanking panel turnover valve is provided with between Article 2 band conveyor and Article 3 band conveyor, stream sieve is provided with below blanking panel turnover valve, stream sieve below arranges Article 3 band conveyor, is provided with lower trolley below Article 3 band conveyor.
Three speed measuring devices are connected with the I34.0 terminal of programmable controller PLC Siemens 300, I34.2 terminal, I34.4 terminal respectively.
Article 1, the QA button switch connection lead of band conveyor is connected with the I31.0 terminal of programmable controller PLC Siemens 300, the QA button switch connection lead of Article 2 band conveyor is connected with the I31.2 terminal of programmable controller PLC Siemens 300, the QA2 button switch connection lead of Article 3 band conveyor is connected with the I31.4 terminal of programmable controller PLC Siemens 300
The 1AQA button switch connection lead of the vibrating motor of hopper, stream sieve is connected with the I32.0 terminal of programmable controller PLC Siemens 300, I32.2 terminal respectively;
Blanking panel turnover valve is connected with the I38.0 terminal of programmable controller PLC Siemens 300.
The utility model eliminates complicated Control, simplifies the structure; Can failure judgement point and can rapidly removing faults fast, handling failure time shorten 50%, fault rate reduces more than 50%, saves a large amount of manpower and materials.
