The utility model discloses a separation membrane production apparatus, which comprises a material dissolving tank and a membrane production tank, wherein the two tanks are communicated through a pipeline. The separation membrane production apparatus is characterized in that an outlet position of the material dissolving tank is provided with a first screw pump for transferring a membrane production liquid in the material dissolving tank to the membrane production tank, and an outlet position of the membrane production tank is provided with a second screw pump for outward discharging the membrane liquid and forming a membrane. With the utility model, pollution and interference of nitrogen on a membrane production liquid in the nitrogen-metering pump method is avoided so as to improve membrane product quality, shorten a membrane production liquid deaeration time, reduce the repair step at the later stage, and improve production efficiency.
