| Summary: | Aiming at the problems of poor mixing effect and uneven material mixing in the practical production of the multifunction wood plate double screw mixer. In this paper,the mixing structure is optimized,and the original single-axis double-helix mixing structure is replaced by the double-axis double-shear double-helix mixing structure. With waste wood chips,magnesium oxide and other additives as raw materials,EDEM simulation software was used to simulate the motion of the stirring process and the mixing simulation of different added materials. It is concluded that the improved double-shaft mixer works better than the structure before the improvement. On the basis of this conclusion,by modifying the Angle parameter of the stirring blade and changing the rotation speed of the stirring shaft,it is concluded that the installation Angle of the stirring blade is about 45 ° and the stirring speed is about 180 r/min. Finally,the dynamic finite element analysis of the actual mixing process is carried out to ensure the feasibility of the optimized design. |
