Powder material conveying apparatus

The utility model relates to a transportation device for powdery materials, which comprises a tee joint structure body in an inverse T shape. The vertical section of the body is a feeding pipe. One end of the horizontal pipe is an intake end embedding a gas nozzle which is longer than the distance between the end and the central line of the feeding pipe while the other end is a discharge section which first narrows slightly and then enlarges slightly. The neck of the discharge section is positioned on the half or so of the entire discharge section. The joint inner wall of the intake pipe of the body and the horizontal pipe of the body is jointed transitionally in an arc shape. Flange structures are connected with the end of the intake pipe and the pipe ends of both the intake section and the discharge section. The utility model has the advantages of simple structure, continuous and reliable operation and high transportation efficiency.
