Method and apparatus for spraying powdered material using pulsating vibration air

摘要

Spray and method for spraying powdered material activated by pulsating vibration air. The spray comprises an elastic membrane (3), a tank (2) for storing powdered material provided with the elastic membrane (3) at the bottom opening (2a), and a pulsating vibration air generating means (4) for supplying pulsating vibration air to the elastic membrane (3). The spray such constructed is designed to uniformly and diffusely spray the powdered material stored in the tank (2) when the elastic membrane (3) is forcedly vibrated up and down in compliance with the frequency of the pulsating vibration air by receiving pulsating vibration air from the pulsating vibration air generating means (4). <IMAGE>
