<p>A powder injection device includes a main body unit (1) that injects pressurized gas which is introduced from an air supply pipe (12) as a gas mixture, along with powder (W) flowing down from a hopper (14), from an exhaust pipe (15), and the air supply pipe (12), the hopper (14), and the exhaust pipe (15) are connected to the main body unit (1). The main body unit (11), the air supply pipe (12), an adapter (13), the hopper (14), and the exhaust pipe (15) are assembled into a single unit and accommodated in a casing (20). A pressurized gas source (30) is mounted on the adapter (13) from outside of the casing (20), and a powder container (40) that accommodates the powder (W) is mounted on the hopper (14). Using the configuration, it is possible to stabilize the amount of the powder that is injected in the gas mixture.</p> |
