Modeling of Drum Livestock Manure Treatment Equipment Based on SolidWorks and Experimental Study on Influencing Factors of Fermentation Performance

With development of livestock industry，more and more researchers pay attention to treatment of livestock manure.In order to solve problems of low efficiency and high power consumption in current livestock manure treatment，treatment efficiency and power consumption of drum livestock manure treatment equipment were analyzed.First of all，according to working principle，structure and technical parameters of drum livestock manure treatment equipment，SolidWorks was used to analyze drum system，feeding and discharging system，and rack system for virtual prototype analysis，and construct complete machine model of drum type manure treatment equipment.Secondly，orthogonal test method was used to analyze influence of the 3 factors（drum temperature，drum speed and drum loading）on equipment processing efficiency and power consumption.Results showed that，factors affecting experimental indexes of drum treatment efficiency from large to small were loading capacity，fermentation temperature and drum speed.Optimal combination was C1A3B3，that was，loading amount was 50%，fermentation temperature was 70 ℃，and drum speed was 0.4 r/min.Factors affecting power consumption test index of drum treatment from large to small were loading capacity，drum speed and fermentation temperature.Optimum combination was C2B2A1，that was，loading amount was 60%，drum speed was 0.3 r/min，and fermentation temperature was 60 ℃.Through comprehensive analysis，loading capacity of drum was the most important factor affecting treatment efficiency and cost of equipment.
