A gas-replaceable compound fertilizer fermentation production device

Abstract

This utility model relates to the field of fertilizer production technology, and in particular to a gas-replaceable compound fertilizer fermentation production device, including a fermentation tank. The air inlet of the fermentation tank is concealed within a gas exchange mechanism. The gas exchange mechanism includes a central adjustment box and two side mounting boxes. The adjustment box contains a coaxially rotating rotary cylinder and a rotating disk. A fixed column is mounted on the rotating disk. A waist-shaped movable ring is slidably fitted around the fixed column. Movable rods extend outward from both sides of the waist-shaped movable ring. A slide valve is installed inside the mounting box. The front ends of the movable rods are respectively mounted on the corresponding slide valves and control the opening and closing of the slide valves. The slide valves control the entry of external gas into the fermentation tank. The fermentation tank proposed in this utility model can achieve rapid conversion between air and nitrogen through the rotation of the rotary cylinder. The operator can change the gas type in a timely manner according to the fertilizer fermentation situation, which can ensure the fermentation effect of the fertilizer.
