AI Technical Summary
Supercritical fluid foamed particles are prone to agglomeration and clumping in storage environments with high humidity and poor ventilation. This results in poor uniformity of the screening equipment, and the screening equipment only has two screening screens, making it difficult to adapt to the screening of particles with multiple particle sizes, thus affecting screening efficiency and practicality.
A device comprising a screening frame, a feeding assembly, a support frame, a rotating frame, and multiple screening cylinders was designed. It utilizes a vibration motor to disperse particles, and combines a servo motor to drive the rotating frame and screening holes of various sizes to achieve uniform particle distribution and multi-particle-size adaptive screening.
It improves particle screening efficiency and equipment usability, avoids local accumulation, and ensures uniform particle distribution and multi-size adaptable screening.
