摘要
该机采用了活塞冲压成型,避免了生物质原料与成型部件的连续接触摩擦;解决了螺旋推进成型机螺旋杆头部磨损严重的问题,使易损件的寿命由50h延长到200h;单位产品能耗由125kW·h·t-1降到40~65kW·h·t-1。成型棒密度为900~1300kg·m-3,可直接碳化成炭棒,投资回收期为3个月,益本比B/C>2.6,且设备简单、紧凑,机组成本低,适合在广大农村推广。
To aviod the friction between rough material and the briquetting parts and to solve the wear problem of screw type biomass briquetting machine,this machine is designed for briquetting with a piston.As a result,the lifetime of easy wear parts is prolonged from 50 to 200 hours,energy consumption of unit product decreases from 125 kW·h·t -1 to 40~65kW·h·t -1 .The density of the compressed stick ranges between 900~1 300kg·m -3 and it can be carbonized directly.Its returned period of investment is about 3 months and the Benefit Cost Ratio B/C is over 2.6.The machine is simple,compact and cheap.So it is suitable for popularization in the vast countryside.
