ブロワ−の容量が大となり、ランニングコストも大とな
らざるを得ない。In general, gas transportation methods can transport powder and granules with high efficiency, but when the concentration of powder and granules is increased, the phenomenon of accumulation of powder and granules at the bottom of the tube occurs, so it is difficult to transport powder and granules. It is necessary to lower the mixing ratio or increase the gas flow rate. Therefore, the flow rate of the transport medium must be increased;
The capacity of the blower becomes large, and running costs inevitably become large.
又、粉粒体が湿っていると、ブロック状態が生じ、輸送

により、粉粒体の流動抵抗を減少させつつ、該粉粒体の
撹拌及び乾燥を行う方法がとられていた。Conventionally, as a transportation method that attempts to solve the above-mentioned inconvenience, a circular tube connecting each device is rotated and heated to reduce the flow resistance of the powder while stirring and drying the powder. There was a way to do it.

として残していた。[Problems to be Solved by the Invention] However, in the method of rotating and heating a circular tube as described above, the circular tube must be rotatably supported, and sealing of the support part is also a problem, and the A drive device is also required. Furthermore, the heating device must be installed along the circular tube, which still leaves problems such as the device becomes complicated and the equipment cost increases.

るものである。Means for Solving Problem E] The present invention has been made for the purpose of solving the above-mentioned problems of the conventional art. The present invention is characterized in that the provided twisted pipe is used as a transport pipe for the powder and granular material, and the powder and granular material is transported while creating a swirling flow in the gas of the transport medium by the twisted groove.

行い得る。[Function] The twisted grooves provided on the pipe wall surface can give a swirling flow to the high temperature gas, so the high temperature gas and the powder and granules are mixed and stirred efficiently, and the powder and granules are continuously dried. transportation.
[実 施 例] 以下、図面を参照しつつ本発明の詳細な説明する。[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

媒体として用いる。As shown in FIGS. 1 and 2, a twisted pipe l having three twisted grooves 2 with a pitch p in the pipe axis direction on the pipe wall surface is used as a transport pipe for powder and granules, and a heat exchanger (not shown) is used. A blower (not shown) passes preheated high-temperature gas through
It is fed into a twisted tube l using a method such as the above, and is used as a medium for drying and transporting powder and granules.
