PB-Ⅰ型活塞式生物质成型机的研制

Study on PB I Piston Type Biomass

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.
