【摘要】 本文介绍自行设计的可变风量、风压的风机试验台,筒式风送干贮仓和斗式升运机,对筒仓风送籼稻的主要参数进行了正交择优试验,并作了统计分析。结论是:风机的风量8000m~3/h、风压853Pa、稻谷含杂率控制在2％以下、含水率13～14％、底板开孔率4.4％为筒仓仓底风送排粮较优参数组合方案;其风送残留量为零,功率消耗4.3kW,风送效率8t/h。这种较优参数组合方案,可供筒式风送干贮仓和方仓风送排粮设计参考。更多还原

【Abstract】 Emptying rice storage bins by the action of air from the low pressure blower is an important technique in grain drying and storage. This paper introduces the experimental installation for the blower with adjustable air pressure aad Tolume, the pneumatic discharged cylindrical storage bin, and the bucket ele-rator etc. The main parameters from the orthogonal experiment are statistically analysed and the optimum combination is obtained: air volume of the blower is 8000m3/h, air pressure of the blower is 853pa, impurity content in rice is less than 2%,moisture content of rice is 13%-14%,aperture efficiency of floor is 4.4%, resulting that the discharging residue is zero, power consumption is. 4.3kW, and the discharging capacity of rice by air reaches 8 t/h.更多还原
