Reclaimer is a high-efficiency equipment for continuous loading and unloading of bulk bulk materials in modern industry. It has been widely used in ports, docks, metallurgy, cement, iron and steel plants, coking plants, coal storage plants, power plants and other bulk material storage yards. The operation is mainly composed of bucket wheel device, cantilever belt conveyor, upper steel structure, pitching mechanism, slewing device, portal frame, running device and tail car.
The reclaimer realizes the remote operation and unmanned operation of the reclaimer through the application of three-dimensional coordinate conversion technology, three-dimensional simulation technology of the material pile, and adaptive trajectory algorithm, and enables the entry and exit of raw materials, the automation of coal blending and ore blending, and the belt path. Automatic selection, unmanned reclaimer, real-time dynamic and refined management of the actual performance data of the material yard, to realize the intelligent management of the material yard in front of the iron.
In the remote control system of the reclaimer, the equipment is no longer an independent unit running one by one in the material yard, it is both the “implementer” and the “controller” of the remote control system. In other words, the material yard is unmanned, the equipment identifies itself and then completes the stacking operation according to the set program. The remote control system reflects the action of a single equipment to the PLC or industrial computer in the main control room, and the main control room performs the operation through the established algorithm. The reclaiming action can even deal with unexpected situations spontaneously, and the monitoring of the equipment is very easy and simple.
The remote control system of the reclaimer adopts the cone shell method for stacking materials. By installing two GPS receiving points at the front end of the cantilever beam and the top of the rotating steel structure, the cantilever position and the position of the whole machine are positioned. The 3D scanner installed on the top of the rotating steel structure scans the stockpile, and digitizes it into an electronic chart of the stockpile and equipment through GPS-based stockyard identification and analysis.
The reclaiming operation of the system is converted into a digital model through real-time scanning and analysis, which realizes the automatic stacking and addressing of the stacker and reclaimer, and completes the reclaiming operation. The data of the bucket wheel motor current is fed back, and the footage is corrected and the rotation boundary is judged. In this mode, the stacker-reclaimer can move to the stacking accurately, and operate without interruption. The operation efficiency is high, and it is suitable for transfer terminals with high operation frequency.
