AI Technical Summary
The existing grate cooler has a fixed angle at the front end of the heat exchange grate, which cannot be adjusted according to the amount of material being fed. This results in improper material accumulation thickness or excessive downward speed, affecting the cooling effect.
The system employs an electric push rod and a magnetoelectric speed sensor in conjunction with a PLC controller to automatically adjust the angle of the guide slope by detecting changes in the material feed rate, ensuring that the material forms a suitable layer on the grate and achieving dynamic matching.
It enables automatic adjustment of the guide slope angle according to changes in the material feed rate, ensuring stable material flow and cooling effect on the grate bed, and improving the operating efficiency of the grate cooler.
