Automatic acidification discharging system

The utility model provides an automatic acidification discharging system, and relates to the technical field of material conveying. The problems that feeding control is not flexible, production efficiency is low, environment pollution is serious, and the health of workers is affected are solved. Comprising a dense-phase pump, a buffer bin, a variable-frequency rotary valve, a fixed-frequency weighing screw feeder, an acid mixing machine and an acidification kiln, the dense-phase pump is connected with the buffer bin in a sealed mode, the buffer bin, the variable-frequency rotary valve, the fixed-frequency weighing screw feeder, the acid mixing machine and the acidification kiln are sequentially connected from top to bottom in a sealed mode, and a fluidization gas set is arranged at the bottom of the buffer bin. According to the automatic acidification discharging system, the synergistic effect is achieved, the continuity of the operation process is good, the feeding amount can be flexibly and accurately contr
