DEVELOPMENT OF SYSTEM OF SNOW TRANSPORT THROUGH PIPE LINE WITH COMPRESSORS

在S私家院子、小路、屋顶等狭小空间中，利用管道高速气流输送积雪，可以更有效、更高效地清除积雪，甚至是湿雪和大雪。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。气流的速度越高，移动的力量就越大，管道中积雪的可能性就越小。避免积雪堵塞的气流速度应在30m/S以上，雪粒进入管道的直径应在2cm左右。延长输送距离很容易通过串联“单元”来实现，其中一个单元由管道、喷嘴组和空压机组成。通过这种连接，相同距离的积雪输送所需的功率将比一个“单位”更少，而且由于管道中的静压与大气压力相差不大，因此向管道上投放积雪将变得容易。至于向管道中投放积雪，必须将湿雪均匀地分成直径在2厘米以下的小块，以避免积雪堵塞。鼓风机非常有用，可以把积木扔进管道里。

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.
