AI Technical Summary
Existing petroleum coke screening devices tend to accumulate petroleum coke when it is fed in, leading to a decrease in screening efficiency.
The motor drives the lead screw to move the lower feed box left and right, causing the inner guide pipe to slide along the outer guide pipe. Combined with the stirring rod, the petroleum coke is evenly dispersed and broken up to prevent accumulation.
This method achieves uniform dispersion of petroleum coke, improves screening efficiency, and prevents the decline in screening efficiency caused by accumulation.
