新型倾斜螺旋叶片滚筒

New type tilt helical vane drum

打破了传统的采用正螺旋叶片设计滚筒 ,。首次采用倾斜螺旋叶片设计滚筒。利用空间解析几何建立了倾斜螺旋叶片的数学模型。对 2种滚筒的结构和煤流的分析表明 。

It is the first to use the tilt helical vane to design the drum of the coal_winning machine,which breaks through the traditional drum design ways of the coal_winning machine.The mathematic mold is founded in space analytic theory.The structure analyses and coal flow analyses of the tilt helical vane drum and the helical vane drum make clear that the loading capability of the tilt helical vane drum is larger than that of the helical vane drum.
