The nicotinamide hydrate liquid purification device according to claim 4, characterized in that: The side of the friction soft brush (33) away from the first transmission shaft (31) is rotatably connected to the inner wall of the discharge plate (34); the side wall of the first transmission shaft (31) penetrates the purification cylinder (20), and the side wall of the first transmission shaft (31) is rotatably connected to the inner wall of the purification cylinder (20).

6. A nicotinamide hydrate liquid purification process, applied to a nicotinamide hydrate liquid purification device as claimed in claims 1-5, characterized in that: The following steps are involved: S1. The staff introduces the nicotinamide hydrate liquid and anhydrous ethanol into the purification cylinder (20) through the anhydrous ethanol inlet pipe (5) and the liquid inlet pipe (6) respectively, and performs crystallization purification on them; S2. When the nicotinamide crystallization is completed, the first driving motor (30) drives the stirring blade (32) to rotate via the first transmission shaft (31) so that the nicotinamide crystals are separated from the purified waste liquid; S3, the purified waste liquid enters the waste liquid storage cylinder (27) through the liquid discharge pipe (22), and the purified waste liquid is purified and filtered through the purification filter plate (26); S4. After the nicotinamide crystals enter the melting cylinder (40), the water inlet pipe (41) transports pure water into the melting cylinder (40) to mix with the nicotinamide crystals. The second drive motor (46) drives the rotating blades (44) to rotate through the second transmission shaft (47) and the load-bearing circular plate (43) to increase the melting rate of the nicotinamide crystals.
