News from Beijing Jingneng Qinhuangdao Thermmal Power 2*35MW Cogeneration Project Site, two sets 1500t/h capacity cantilever type bucket wheel stacker reclaimer was officially under operation.
Product Name: Cantilever Type Bucket Wheel Stacker Reclaimer
Supplier: Henan Weihua Heavy Machinery Co., Ltd.
Employer: Jingneng Qinhuangdao Thermal Power Co., Ltd.
Job: The core equipment of the coal conveying line of the power plant, responsible for the storage and transportation of coal in the power plant.
Model: DQL1100/1500·30
Normal usage: 1 use and 1 backup, or 2 machines can run at the same time
Stacking capacity: 1500t/h
Reclaiming capacity: 300~1100t/h (adjustable by frequency conversion)
Working coverage radius: 30m
Stacking height: 11m above the rail, 1.5m below the rail
Rotation angle: ±110°
Boom tilt angle range: +10°~-13.9°
1. Multiple operation modes, free and seamless switching.
Single action mode, manual mode, automatic mode and local mode can be switched freely according to different operation requirements without any interference influence.
2. Automatic controllable operation, real-time data feedback.
The PLC main control device realizes the fully automatic control of the operation of the stacker reclaimer, collects the stack shape data through the coal tray, and feeds back the storage situation of the stockyard in real time.
3. Three-dimensional anti-collision, accurate and reliable positioning.
The three-dimensional three-dimensional anti-collision system is based on high-reliability and high-precision positioning system detection and attitude detection to realize anti-collision between equipment and stockpiles, equipment and equipment, equipment and devices along the track.
4. Timely warning reminder, double safety protection.
Set up mechanical and inductive limit switches at each operating mechanism, and set up early warning prompts and limit stop points in program monitoring to establish double safety protection.
5. Dual-line intelligent lubrication, reduce labor intensity.
The equipment adopts electric centralized lubrication as a whole, which greatly reduces the labor intensity; adopts a dual-line intelligent centralized lubrication system arrangement, the lubrication effect of the front and rear lines does not affect each other, and the intelligent monitoring system can indicate the point of failure and reduce the intensity of manual investigation.
6. One machine with multiple functions, high cost performance.
It adopts a full-function double-trailer layout to realize the function of stacking and fetching materials, one machine with multiple functions and high cost performance.
Working link of coal conveying line
Stacking material: external train transportation of coal → wagon dumper system → coal drop pit → ground conveyor belt system → bucket wheel stacker and reclaimer → coal storage yard
Reclaiming: coal storage yard → bucket wheel stacker reclaimer → ground conveyor belt system → coal storage bin → transfer belt system → boiler
Self-stacking and reclaiming operations
Stacking material: coal → ground belt conveyor → auxiliary tail car → main tail car → main tail car head hopper → boom belt conveyor guide trough → boom belt conveyor → coal storage yard
Reclaiming: Coal → Bucket Wheel Mechanism → Boom Belt Conveyor → Central Blanking Hopper → Ground Belt Conveyor
