The utility model relates to the technical field of LNG (Liquefied Natural Gas) production, in particular to a cryogenic liquefaction separation device for LNG production, which comprises a box body, a refrigerant heat exchanger, a methane separator, a runner pipe and a discharging mechanism, the refrigerant heat exchanger is vertically arranged in the box body, the methane separator is fixedly arranged on one side of the box body, and the runner pipe is arranged in the box body. The discharging mechanism is movably installed in the box body and used for automatically discharging pearlife in the box body, the servo motor rotates to drive the chain wheel and the chain to conduct transmission, so that the two threaded rods rotate synchronously, the two movable blocks and the hinge rod move synchronously, and the discharging mechanism is used for automatically discharging the pearlife in the box body. The two push plates are arranged in the box body, so that the two push plates push pearlife to move outwards in
