AI Technical Summary
Existing screw conveyors are not effective at emptying benzoic acid from ton bags, and the emptying process easily generates dust and impurities, leading to waste of benzoic acid.
A closed-loop screw feeder for benzoic acid in ton bags was designed. It uses an electric telescopic rod and a cutter assembly to cut the bottom of the ton bag, and suspends and moves the ton bag through a support assembly. Combined with a sealing structure, it prevents dust from entering and achieves automated feeding.
This method enables the complete discharge of benzoic acid from the ton bag, avoiding airborne dust and pollution, and improving feeding efficiency and material purity.
