High-temperature wood fiber stuff flash evaporation and dewatering all-in-one machine

The utility model relates to a high-temperature wood fiber stuff flash evaporation and dewatering all-in-one machine, which belongs to the technical field of production of wood fiber boards. The technical scheme includes that a flash evaporation groove inner part (6) is arranged in a flash evaporation groove (5), a dewatering machine (8) is disposed at the bottom of the flash evaporation groove, a high-temperature wood fiber stuff inlet (1) is arranged on the flash evaporation groove, a dewatered wood fiber outlet (2) is arranged on the dewatering machine, a flash evaporation steam outlet (3) is arranged at the top of the flash evaporation groove, and a drained water outlet (4) is arranged at the bottom of the dewatering machine. After a part of steam water and a part of liquid water of high-temperature wood fiber stuff (wet fibers) are separated and recycled, the high-temperature wood fiber stuff then enters a drying pipe to be dried, the utilization quantity of drying gas is greatly reduced, the difficult p
