The utility model discloses a mercury separating and screening device for scrap fluorescent lamp tubes. The mercury separating and screening device comprises a roller mechanism connected with a drive mechanism, wherein the roller mechanism comprises a roll shaft and a barrel-shaped screen mesh coaxially arranged on the roll shaft, the mercury separating and screening device for the scrap fluorescent lamp tubes also comprises an outer barrel hermetically arranged on the outer side of the roller mechanism in a covering manner, the outer barrel is provided with a feed inlet, the other end of the feed inlet extends to an inner cavity of the roller mechanism, a heating device is arranged on the inner wall of the bottom of the outer barrel, a gap is formed between the heating device and the screen mesh, and the top of the outer barrel is also provided with an exhaust opening connected with a mercury vapor collection device. The device disclosed by the utility model can carry out rapid heating on fragments of the scrap fluorescent lamp tubes so as to rapidly separate mercury vapor, and therefore, the recovery efficiency of mercury in the scrap fluorescent lamp tubes is increased, and a situation that the mercury in the scrap fluorescent lamp tubes causes relatively serious pollution to the environment can be effectively prevented.
