SUBLIMATION PURIFYING APPARATUS

摘要

PURPOSE: A sublimation purifying apparatus equipped with the sagging preventive unit of a vacuum chamber is provided to improve the durability of the apparatus by adjusting the height of a separator to support the vacuum chamber. CONSTITUTION: A sublimation purifying apparatus includes a heating furnace(10), an internal pipe(20), a plurality of refractory materials(30), and a sagging preventive unit(40). The heating furnace includes a main body(11), a vacuum chamber(13), and a heater(15). The vacuum chamber is embedded in the main body. The heater surrounds the vacuum chamber. The heater secures temperature gradient according to the flowing direction of fluid. The internal pipe includes a receptor(21) and an acquisition pipe(23). The receptor is arranged at one inner side of the vacuum chamber. Organic materials to be refined are received in the receptor. The internal pipe is arranged at another inner side of the vacuum chamber. The acquisition pipe acquires scattering organic materials to be refined according to temperatures. The refractory material surrounds the vacuum chamber by regions. The sagging preventive unit includes a separator(41) and a height adjusting hole(42).
