Designand Analysis of Grain Suction Machine Based on Gas-Particle Two-Phase Flow
In view of the current problems of low efficiency,high labor intensity and poor working environment of domestic storage bulk grain,based on the principle of pneumatic conveying,a mobile grain suction machine is de-signed,the overall layout of the equipment is carried out,and the key parts are optimized.Taking wheat grains as the research object,based on the gas-particle two-phase flow theory,the key parameters of the equipment,wind pressure and air volume,the influence of the area ratio of the inner and outer cylinders of the suction nozzle and the pneumatic conveying speed on the yield and resistance of the suction nozzle of the grain suction machine are experimentally analyzed,the experimental results show that when the area ratio of the inner and outer cylinders is 0.56,the conveying wind speed is 24m/s,and the conveying output is the highest.
