Abstract:
A precision fine powder dispersing supply apparatus for supplying fine powder to a subsequent process in a dispersed state comprising:a fine powder storage vessel; a minute amount supply feeder; a supply device for supplying fine powder in said storage vessel to said minute amount supply feeder; a discharging device for discharging said fine powder from said minute amount supply feeder to said subsequent process; and a heat device is disposed in a transportation path of said fine powder from said fine powder supply feeder to said subsequent process, wherein said minute amount supply feeder comprises: a rotary body having at least one circumferential groove which is filled with the fine powder and formed on an outer circumferential surface; at least one thin pipe disposed so that the opening thereof faces said at least one circumferential groove with a predetermined interval defined therebetween; at least one filling device for forcing and filling said fine powder into said at least one circumferential groove of said rotary body; a pressure difference generating device for generating a pressure difference for causing an air flow from a space in which said rotary body is disposed into said at least one thin pipe so that the fine powder that is forced into and filled in said at least one circumferential groove of said rotary body is discharged together with air; and a fine powder presence sensing device disposed in front of and behind said at least one thin pipe to confirm whether or not the fine powder that is forced into and filled in said am least one circumferential groove of said rotary body exists therein and whether or not the fine powder is discharged therefrom.
