Acetylene generator feeding system

The utility model discloses a feeding system of an acetylene generator. The system comprises a feeding hopper, an upper valve, an upper storage hopper, a lower valve, a lower storage hopper, a discharging oscillator and an acetylene generator which are connected in sequence, the upper valve and the lower valve are respectively provided with an independent driving air source, each independent driving air source is composed of an air storage tank, an air conveying pipeline connected with the air storage tank, the upper valve and the lower valve and an air storage tank pressure controller, and anair program control valve and an air storage tank pressure sensor are arranged at an inlet and an outlet of the air storage tank respectively. The system can ensure that the upper and lower valves act to drive an air source, thereby effectively solving the problem that the upper and lower valves are not tightly closed due to low air pressure of the system, so that acetylene gas is exhausted intoair to cause potential saf
