AI Technical Summary
In the coal sample preparation process, when the moisture content of the discarded sample is high, it is easy for it to pile up at the bend of the pipe and cause the pipe to become blocked. Existing anti-blocking structures are complex, costly, or unsuitable.
An electric heating belt is wrapped around the pneumatic conveying pipeline, combined with a U-shaped ring and insulation cotton. Heating reduces the accumulation of waste samples at the bends in the pipe, and the heating power is adjusted by monitoring the resistance through a power pump.
It achieves full-coverage heating of the bend, reduces the accumulation of waste samples, avoids pipe blockage, improves conveying efficiency, and has a simple structure and low cost.
