Equipment special for purification of high-vacuum organic micro-molecules during continuous feeding and discharging

Abstract

The invention discloses equipment special for purification of high-vacuum organic micro-molecules during continuous feeding and discharging. The equipment comprises a motor, a magnetic fluid sealing shaft, a worm, a storage barrel, a heating furnace inner container, a vacuum gauge, a quartz boat, an observation window, an equipment frame, a collection tank, a pipeline and a five-temperature-zone heating furnace body; the top of the storage barrel is fixedly connected with the motor, the motor is rotatably connected with the top of the worm through the magnetic fluid sealing shaft, and the wormextends into the storage barrel; a discharging port of the storage barrel is fixedly connected with the top of the vertical heating furnace inner container, a discharging port of the heating furnaceinner container is connected with a quartz tube feeding port running through the five-temperature-zone heating furnace body, and a thermocouple is arranged between the five-temperature-zone heating furnace body and a quartz tube. According to the equipment, the problems in existing equipment that a sublimation process is not continuous under a vacuum high-temperature condition, continuous operation cannot be achieved, correspondingly prepared dosages are relatively low under the same condition of time, and therefore the yield of the purified organic micro-molecules is influenced.

Description

technical field [0001] The invention relates to the technical field of equipment for continuous large-scale mass production of high-quality, high-purity organic photoelectric materials, in particular to a special equipment for continuous feeding and discharging of high-vacuum organic small molecules. Background technique [0002] OLED display technology has the advantages of self-luminescence, wide viewing angle, high contrast, low power consumption, high response rate, full-color and simple manufacturing process, etc., and has a good application prospect in the field of high-end display. However, at present, many methods can only be purified and collected in small batches, and it is difficult to reduce the cost, which seriously restricts its industrial application. [0003] In order to meet the urgent demand for material purification in the field of OLED materials, vacuum sublimation equipment is mostly used for the existing organic small molecule purification technology on...
