Example 1:
the automatic measuring device of the distribution condition of the blast furnace charge level is used for monitoring the charge level data in the blast furnace during work.
After the blast furnace starts to work, the microwave chip box in the detection unit starts to send microwave signals in a frequency range of 20-30G, the microwave signals enter the antenna horn after running through the microwave channel through the adapter, and the antenna horn gains the microwave signals and then shoots the microwave signals into the blast furnace. Microwave signals are reflected after contacting the material surface in the blast furnace and enter the microwave chip box through the antenna horn and the microwave channel.
Meanwhile, the servo motor 21 in the motion mechanism rotates, the planetary reducer 22 drives the rotating shaft 34 to rotate, and the rotation of the rotating shaft 34 drives the detection unit connected with the rotating shaft to rotate integrally.
In order to ensure that the microwave signals can traverse all the positions of the burden surface, the steering time of a servo motor 21 in the movement mechanism is set according to the actual size of the burden surface in the blast furnace, and the limit position of the rotation angle of the detection unit is controlled.

Meanwhile, the detection unit is driven to rotate through the movement mechanism, the rotation angle is controlled through the servo controller and the PLC, the microwave signals can traverse the whole charge level, and the height data of each position of the charge level can be accurately measured.
And because the primary ore material and the primary coke material of the blast furnace burden distribution can deeply calculate the ore-coke ratio of each time according to the collected data, the resource utilization rate is improved, and the fuel is saved.
