摘要
根据破壳油菜籽的物料特性,设计了一种气流上吸与振动筛相结合的破壳油菜籽分选机,对分选原理和主要结构参数进行了分析,研究了喂入量和前、后风道风速对分选效果的影响。试验结果表明,喂入量对壳中含仁率的影响存在最佳值点;前风道风速对壳中含仁率和仁中含壳率的影响比后风道风速更大;喂入量为750 kg/h和前、后风道风速分别为1.5 m/s、5.3 m/s条件下,分选机损失率较低。
According to the material properties of hulling rapeseed,a kind of hulling rapeseed separator was designed by combination air suction above the sieve with shaker.The separation principle and the main structural parameters were analyzed.It was studied that the separation result was affected by feeding volume,wind speed of front wind tunnel as well as wind speed of behind wind tunnel.The results showed that there was an optimal value for the effect of feed volume on rate of the hull containing kernel.Comparing with wind speed of behind wind tunnel,wind speed of front wind tunnel had more effect on the rate of hull including kernel and the rate of kernel including hull.The loss rate of separator was lower when feeding volume,wind speed of front wind tunnel,wind speed of behind wind tunnel were 750kg/h,1.5m/s,5.3m/s.
