Embodiment 1
[0036] In order to avoid that when the weighing hopper is jammed, the on-site personnel cannot deal with it in time, resulting in insufficient furnace charge delivered to the blast furnace. This embodiment provides a monitoring and control method for weighing hopper jamming, as figure 1 shown, including:
[0037] S100: The minimum discharge volume of the preset weighing hopper is recorded as ΔX min And the weighing interval time Δt.
[0038] S200: The PLC controller collects the discharging amount of the weighing hopper within the weighing interval time. Specific process such as figure 2 Shown:
[0039] When the discharge condition under the tank is met, the gate at the bottom of the weighing hopper is automatically opened, and by detecting the discharge amount of the weighing hopper during the discharging process, it is judged whether there is a material jam failure during the discharging process of the weighing hopper.
[0040] S201: Collect the weight of the weighing b...
Embodiment 2
[0048] In order to make the weighing hopper of the system get stuck, the system will automatically generate an alarm to remind the operators to perform maintenance and inspection. This application also provides another method for monitoring and controlling the material stuck in the weighing hopper, such as image 3 shown, including:
[0049] S100: The minimum discharge volume of the preset weighing hopper is recorded as ΔX min And the weighing interval time Δt.
[0050] S200: The PLC controller collects the discharging amount of the weighing hopper within the weighing interval time. Specific process such as figure 2 Shown:
[0051] When the discharge conditions under the tank are met, the gate at the bottom of the weighing hopper is automatically opened, and by detecting the discharge amount of the weighing hopper during the discharging process, it is judged whether there is a material jam failure during the discharging process of the weighing hopper.
[0052] S201: Colle...
Embodiment 3
[0062] Such as Figure 4 As shown, during the smelting process of the blast furnace, the sintered ore and coke are sent to the bin 1 through the belt on the tank, and then put into the weighing hopper 2 through the feeder for material preparation. Finally, the charge is placed on the belt 3 under the trough through the gate of the weighing hopper, and then transported to the blast furnace cabin through the belt 3 under the trough for smelting. When the weighing hopper 2 sends an empty signal, close the valve of the weighing hopper, and then prepare materials for the weighing hopper, and so on.
[0063] This embodiment discloses a weighing hopper material jam monitoring and control system, including: a weighing sensor 5, a vibration motor 7, and a PLC controller 6; wherein,
[0064] The weighing sensor 5 is connected with the weighing bucket 2 for weighing the weighing bucket.
[0065] The PLC controller 6 is electrically connected with the load cell 5 and the vibration motor...
