Silver powder automatic conveying system

Abstract

This utility model discloses an automatic silver powder conveying system, including a silver powder hopper, a rotary valve, a hose, an acceleration chamber, a connecting pipe, a conveying pipe, and a Roots blower. A group of acceleration chambers are connected in series on the same conveying pipe via connecting pipes. One end of the conveying pipe is connected to the outlet of the Roots blower. The top port of each acceleration chamber is connected to the output port of the rotary valve via a hose, and the input port of the rotary valve is connected to the bottom port of the silver powder hopper. The advantages of this utility model are: by having multiple electrically driven rotary valves at the bottom of the silver powder hoppers open at equal intervals, the conveying pipe is kept in a non-full state, preventing the amount of silver powder being conveyed from obstructing the next material drop point; and by using the acceleration chambers and the Roots blower, the automatic conveying speed of the silver powder is improved, achieving dust-free silver powder output.
