AI Technical Summary
The existing pulverized coal boiler feeding device is prone to fluctuations during the feeding process, which makes it impossible to deliver pulverized coal in a normal quantitative manner.
The design employs a combination of a lifting mechanism, a guide ramp, a fixed ring, and a blocking block. The lifting mechanism drives the blocking block to move up and down within the fixed ring, thereby achieving quantitative conveying of pulverized coal.
It enables quantitative feeding of pulverized coal boilers, solves the problem of large fluctuations in feed, and ensures uniform distribution of pulverized coal.
