Design and simulation analysis of powder disposal system for 3D printing mold steel
In this paper,we design a powder disposal system for the whole process of metal 3D printing,completed the overall structure design of the system,and designed the components of power unit,conveying pipeline,feeder,separator and sieving device through relevant parameter calculation.FLUENT software was used to simulate and analyze the flow of 18Ni-300 mold steel powder in the system.The results show that increasing the airflow velocity at the inlet of powder supply pipe can improve the flow state and conveying effect of powder in the pipe.With the increase of the bend diameter ratio of the bend pipe,the powder conveying rate will increase and the pressure loss will decrease.Decreasing the separator cone angle will lead to an increase in separator separation efficiency and a decrease in internal pressure loss.Increasing the inlet airflow velocity of the waste recovery duct can increase the recovery rate of the waste in the screening unit.
