WIPO Patent Application WO/2024/024539

A1

The present invention suppresses the degradation of ejector effect in a spraying apparatus equipped with an ejector and can ensure a prescribed powder emission quantity. A spraying apparatus 1 according to the present invention is provided with: a storage means 20 for storing a powder 10; an ejector 30; a transportation tube 40 through which a mixture generated by the ejector is transported; and an emission means for emitting the mixture transported through the transportation tube 40. The ejector 30 is provided with: a container part 31 that has an internal space which is in communication with a dispensing port 21 of the storage means 20; and a jetting nozzle 32 that jets out a pressurized carrier gas from the leading end thereof into the internal space. The leading end of the jetting nozzle 32 is situated on the side closer toward the transportation tube 40 as compared with a vertical center line A passing through the center of the dispensing port 21. The minimum distance Y from the leading end of the jetting nozzle 32 to the inner circumference of the container part 31 is included within a range that satisfies 2X≤Y≤4.19ln(X)+26.74, where X represents the maximum particle diameter of the powder. The maximum particle diameter of the powder 10 is 0.03-5 mm.
