| Abstract:This article studied a kind of new way to design helical line which was applied in sludge dewatering screw press device based on the principle of solid material balance in the entrance and exit of the drive, the mathematical model of screw axis with equal diameter and variable pitch was derived based on dewatering parameters, and FLUENT was used to simulate the fluid model established by this mathematical model, the pressure and velocity distribution cloud of the flow field were obtained, then the results of post processing to verify the reliability and practicability of the screw press, and provide a kind of new theoretical method to design and analyze the sludge dewatering screw press device. |
