[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] This application provides an automated pre-batching and stacking production line, referencing... Figs. 1-2 ,include:

[0026] Weighing sensor 1, weighing controller 3, first AI module 4, second AI module 7, radar level gauge 5, signal isolator 6, wherein,

[0027] The weighing sensor 1 is installed on the belt scale. The weighing sensor 1 is connected to the input terminal of the weighing controller 3 through the wire 2. The output terminal of the weighing controller 3 is connected to the input terminal of the first AI module 4 of the PLC.

[0028] The radar level gauge 5 is installed at the upper end of the sintered ore finished product silo. The radar level gauge 5 is connected to the input end of the signal isolator 6, and the output end of the signal isolator 6 is connected to the input end of the second AI module 7 of the PLC.

[0029] In some embodiments, the weighing sensor 1 is a Korean CAC sensor.

[0030] In some embodiments, the weighing controller 3 is model DXK-2010.

[0031] In some embodiments, it also includes:

[0032] The input terminal of the photoelectric converter 8 is connected to the output terminal of the second AI module 7.

[0033] In some embodiments, it also includes:

[0034] Ethernet switch 9, the input of which is connected to the output of photoelectric converter 8 and first AI module 4.

[0035] In some embodiments, it also includes:

[0036] The background computer 10 is connected to the output of the Ethernet switch 9.

[0037] Specifically, the automated pre-batching and stockpiling production line includes a pre-batching silo belt scale control section and a sintered ore finished product silo radar level gauge 5 monitoring section. The pre-batching silo belt scale control section includes a weighing sensor 1, a weighing controller 3, and a first AI module 4. The sintered ore finished product silo radar level gauge 5 monitoring section includes a radar level gauge 5, a signal isolator 6, a second AI module 7, and a photoelectric converter 8. Both the pre-batching silo belt scale control section and the sintered ore finished product silo radar level gauge 5 monitoring section are connected to a back-end computer 10 via an Ethernet switch 9. The radar level gauge 5 outputs a 4-20mA signal, which is isolated by the signal isolator 6 before being output to the PLC's AI module. This signal is then transmitted via the photoelectric converter 8 to the Ethernet switch 9 and the back-end computer 10 for display and control.

[0038] Specifically, the pre-batching and stockpiling production line will be upgraded to a computer-automated system. The pre-batching power distribution room will purchase and install a back-end computer (10), PLC cabinet, weighing and metering sensors, and other automation-related equipment, and lay and install power supply and signal transmission lines for the new equipment. An ultrasonic level gauge will be added to the finished product warehouse and connected to the back-end computer (10) in the sintering main control room.

[0039] In summary, compared with existing technologies, the batching bins in the automated pre-batching and stockpiling production line provided in this application can measure and transmit the material feed in real time, facilitating timely detection and adjustment of the feed of various mineral raw materials, reducing the batching ratio deviation (to ±1%), and effectively improving the stability of the blended ore stockpile quality. Because the quality of the pre-batched blended ore is improved, the unstable factors of elemental fluctuations during the sintering process are reduced. This creates favorable conditions for providing high-quality sinter for the blast furnace. It facilitates accurate measurement, reasonable optimization of ore blending, and reduces the blending cost of the stockpile. After installing radar level gauges in the finished product bin, the material level can be monitored and observed in real time. Images can be sent to the ironmaking plant production group via a back-end computer for easy viewing by personnel at all levels, thereby enabling better adjustment of the sintering production load and blast furnace sinter feed based on the finished product bin level (improving management efficiency).
