Pneumatic transport for connecting pipe and pneumatic transport equipment

摘要

The present invention structure is a simple, can be easily detached without the use of tools, and provides a less eliminating the parts pneumatic transport for connection pipe when it is detached. A connection pipe 40 is used for pneumatic transport device for pneumatic transport of the powder particles, removably attached to the pipe 21 for transporting only the gas mixture or the transport gas consists of bulk material and transport gas . Connecting pipe 40 is inserted into the pipe 21 at one end region of the tube axis direction, the tube body 41 an annular recess 41a on the inner peripheral surface is formed in the one end region is arranged in the recess 41a, the tube and an annular elastic sealing member 42 in close contact over the entire circumference on the outer peripheral surface of the pipe in a state in which the pipe is inserted into the body, can be easily attached to connecting tube is simply fitted into the outer pipe. .BACKGROUND 2
