DEVELOPMENT OF SYSTEM OF SNOW TRANSPORT THROUGH PIPE LINE WITH COMPRESSORS

通过管道进行高速气流的雪运输将更好地用于开发更有效和高效的除雪方法，即使是在私人院子、小路和屋顶等狭窄空间内的湿雪和大雪。高速气流是由空气压缩机吹出的压缩空气提供的。运输的移动力也是由空气的拖曳产生的。气流速度越高，移动力越大，雪堵塞管道的可能性也就越小。避免雪堵塞的气流速度宜大于30m/s，抛入管道的雪粒直径宜小于2cm左右。通过串联“单元”，可以很容易地延长运输距离，其中一个“单元”由管道，喷嘴块和空气压缩机组成。通过这种连接，与一个“单位”相比，相同距离的雪运输所需的功率更少，并且由于管道中的静压与大气压力相差不大，因此将雪扔进管道将很容易。在向管道中抛雪时，湿雪必须均匀地破碎成直径小于2厘米的小块，以避免雪堵塞。鼓风机是很有用的，可以把积木扔进管道。

Snow transport by high speed air flow through pipe line will serve better purposes to develop more effective and efficient ways of removing snow, even wet and heavy snow, in narrow spaces such as private yard s, paths, and roofs.The high speed air flow is provided by blowing of compressed air from air compressors. The moving force of transport is also generated by dragging of the air. The higher the speed of the air flow, the greater the moving force as well as the less chances of snow blockages in the pipe line. The speed of the air flow to avoid snow blockages is desirable over 30m/s, and diameter of snow grain thrown into the pipe line is desirable under about 2 cm.Extending the distance of transport is easily realized by joining the "units" in series, of which the one is assembled with a pipe line, a nozzle block, and air compressor. By this joining, less power will be needed for snow transport for the same distance in comparison with one "unit", and throwing snow into on the pipe line will be easy because static pressure in the pipe line isn't so different from atmospheric pressure.As for throwing snow into the pipe line, wet snow has to be broken into small blocks of under about 2 cm in diameter uniformaly to avoid snow blockages. Air blower is very useful to throw the blocks into the pipe line.
