PURPOSE:To certainly form a plug and avoid closure by installing an intermittently opening and closing apparatus at the terminal of a transportation pipe and transporting the plug by the expansion force of gas due to the intermittent opening and closing of the opening and closing apparatus, in the captioned apparatus for transporting powder in plug form. CONSTITUTION:Pressurized gas 2 is supplied into a pressurizing tank 1 filled with powder, and an intermittently opening and closing apparatus 4 is opened and closed at a time intervals set in a time-interval setting device 5. When the opening and closing apparatus 4 is in closed state, the inside of a transportation pipe 3 is field with gas. When the apparatus 4 is opened, the inside gas sharply expands and is blown-out with powder into a receiving container 7. By the next closing operation, the inside of the tnrasprtation pipe 3 is charged. Plugs are transported by the repetition of the above-described operations. With such constitution, plugs can be certainly formed, and closure can be avoided. |
