AI Technical Summary

Technical Problem

When existing screw conveyors process gypsum powder with high moisture content, wet gypsum adheres to the tank wall, forming a ring-shaped accumulation layer, which reduces the effective conveying cross section. Traditional cleaning methods are time-consuming and labor-intensive, and some anti-clogging solutions are energy-intensive and accelerate structural fatigue.

Method used

A special anti-clogging conveyor for gypsum production was designed. It adopts the shearing effect between the scraper blade and the trough wall, combined with the closed-loop control of electric heating tape and humidity sensor. The scraper and trough wall maintain a dynamic gap, the sawtooth structure breaks up the clumps, and the PLC control system dynamically adjusts the heating and speed.

Benefits of technology

It achieves efficient removal of adhering material, reduces energy consumption by 40%, avoids blockage by large particles, maintains stable tank temperature, and improves conveying efficiency and equipment lifespan.
