AI Technical Summary

Technical Problem

After a long time of use, the inner wall of the existing coal pulverized furnace is prone to stick to a large amount of coal pulverized, resulting in poor and uneven cutting, affecting the stability of the furnace.

Method used

An automatic feeding device for pulverized coal furnaces is designed, including a warehouse wall cleaning mechanism, a hopper and a coal powder conveying device. The silo wall cleaning mechanism cleans the coal powder on the silo wall through scrapers and drive devices; the hopper is installed in the silo silo to make the coal powder diffuse around and improve the uniformity of the cutting; the silo conveys coal powder efficiently through the silo conveying shaft.

Benefits of technology

Effectively clean the coal powder on the wall of the coal powder warehouse to ensure smooth flow of coal powder, improve the stability and combustion efficiency of the coal powder furnace, and ensure the uniformity of coal powder cutting.
