Description

Technical Field

[0001] The utility model relates to the technical field of organic luminescent material recovery, in particular to an organic luminescent material recovery and purification device. Background Art

[0002] Organic light-emitting materials are organic materials that can generate photons when organic molecules are excited by light and release energy to return to the ground state. Organic light-emitting materials are divided into OLEDs. The process of recycling and purifying organic light-emitting materials is often to press the powdered material to be purified into a dense state under a predetermined pressure, a predetermined temperature and a required time. When the pressed material to be purified is sublimated and purified, the quality of the purified material collected in a single sublimation purification production process can be increased because the pressed material to be purified is denser than the powdered state.

[0003] Organic light-emitting materials can be subsequently purified after being mixed with purification liquid. However, most of the organic light-emitting materials are in a static state inside the purification device. The efficiency of purification of organic light-emitting materials is poor, and the purification is not sufficient. In addition, the organic light-emitting materials just put into the device are easy to adhere to the inner wall of the device. If the organic light-emitting materials are not cleaned off in time, waste will be caused. Therefore, it is particularly important to design an organic light-emitting material recovery and purification device. Utility Model Content

[0026] Working principle: Organic luminescent material, an organic material that makes organic molecules in an excited state under light excitation, and the excited organic molecules can generate photons in the process of releasing energy to return to the ground state. Organic luminescent materials are divided into OLEDs. The process of recycling and purifying organic luminescent materials is often to first press the powdered material to be purified into a dense state through a predetermined pressure, a predetermined temperature and a required time. When the pressed material to be purified is sublimated and purified, the quality of the purified material collected in a single sublimation purification production process can be increased because the pressed material to be purified is denser than the powder. The recovered organic luminescent material is pressed and put into the interior of the purification cylinder 2 through the funnel 3.

The first scraper ring 10 and the second scraper ring 12 are connected by two vertical rods 11, and the driving sleeve 8 is fixedly sleeved on one end of the driving rod 7. When the driving rod 7 rotates, the driving sleeve 8 and the first scraper ring 10 rotate at the same time, which will drive the second scraper ring 12 to rotate, and the auxiliary ball 15 and the straight plate 17 are connected by the disc 16. The rotation of the driving rod 7 will also drive a number of plastic columns 18 to rotate. The plastic column 18 can stir the organic light-emitting material put into the purification cylinder 2, and the guide pipe 4 can guide the purified liquid to the inside of the purification cylinder 2.
