[0025] When performing separation and purification of organic light-emitting materials, firstly, the organic light-emitting materials to be separated and purified are introduced from the feed port 2 into the separation and purification box 1. In the process of the organic light-emitting materials falling, the organic light-emitting materials are separated by the sub-sieve 14 arranged inside the separation screen plate 13. In the process of separation operation, the organic light-emitting materials in the circulation process are easy to adhere to the sub-sieve holes inside the sub-sieve 14 and cause blockage of the sub-sieve holes. At this time, the separation screen plate 13 can be driven by the vibration component to move inside the separation and purification box 1, and the blocked organic light-emitting materials can be further shaken off by vibration, thereby improving the separation efficiency. The separated organic light-emitting materials will fall to the barrier block 8 and coincide with the inclined surface of the guide hole 19. Contact, further facilitate the diversion of the organic light-emitting material through the inclined surface, so that the organic light-emitting material can smoothly flow into the interior of the purification chamber 12, after the introduction of the organic light-emitting material is completed, close the solenoid valve 10 inside the diversion hole 19, and inject the auxiliary purification solvent through the purification solvent injection port 11, after the solvent flows into the purification chamber 12 and mixes with the organic light-emitting material inside, it is heated by the electric heater 9, so that the mixed organic light-emitting material is distilled and extracted, and finally the extracted steam is discharged by the gas guide channel 18, and finally the purified organic light-emitting material is introduced by the purification discharge component, thereby facilitating the improvement of the separation efficiency by the vibration component, and at the same time cooperating with the distillation and extraction process, the separation and purification efficiency of the organic light-emitting material is improved.

[0026] like Figure 1-Figure 5 As shown, the vibration assembly includes two connecting rods 15, the two connecting rods 15 are fixedly connected to the top of the separation screen plate 13, the outer side of the connecting rod 15 is slidably connected to the separation purification box 1, four springs 17 are fixedly connected between the separation screen plate 13 and the barrier block 8, and one end of the two connecting rods 15 extends to the outside of the separation purification box 1 and is fixedly connected with a pull ring 16.

[0027] The connecting rod 15 is driven to move by pulling the pull ring 16, thereby driving the separation screen plate 13 to slide between the inner walls of the separation purification box 1. During the movement of the separation screen plate 13, the spring 17 is pulled to deform, and the pull ring 16 is further loosened, so that the separation screen plate 13 vibrates under the action of the spring 17, and the organic light-emitting material stuck to the inside of the separation screen 14 is further shaken off by the vibration, thereby improving the separation efficiency.

[0028] like Figure 1-Figure 5 As shown, the purification discharge assembly includes a cooling device 3, which is fixedly installed on one side of the separation and purification box 1, an air guide pipe 6 is fixedly connected between the cooling device 3 and the separation and purification box 1, an output end of the cooling device 3 is fixedly connected to a connecting pipe 5, and one end of the connecting pipe 5 is fixedly connected to a finished product discharge port 4.

[0029] The evaporated steam of the organic light-emitting material mixed liquid is introduced into the cooling device 3 through the air guide pipe 6. After the steam is cooled by the cooling device 3, the cooled liquid is introduced into the finished product discharge port 4 from the connecting pipe 5, thereby facilitating rapid distillation extraction and discharge of the finished product.

[0030] The utility model provides an organic luminescent material separation and purification device, and the specific working principle is as follows: when performing the separation and purification of the organic luminescent material, firstly, the organic luminescent material to be separated and purified is introduced into the separation and purification box 1 from the feed port 2, and in the process of the organic luminescent material falling, the organic luminescent material is separated by the sub-screen 14 arranged inside the separation screen plate 13. In the process of the separation operation, the organic luminescent material in the circulation process is easy to adhere to the sub-screen holes inside the sub-screen 14 and cause clogging of the sub-screen holes. At this time, the connecting rod 15 can be driven to move by pulling the pull ring 16, thereby driving the separation screen plate 13 to slide between the inner walls of the separation and purification box 1. In the process of the movement of the separation screen plate 13, the spring 17 will be pulled to deform it, and the pull ring 16 will be further loosened, so that the separation screen plate 13 is moved under the action of the spring 17. The vibration is generated, and the organic light-emitting material stuck to the inside of the separation screen 14 is further shaken off by the vibration. The separated organic light-emitting material will fall to the barrier block 8 and contact with the inclined surface of the guide hole 19. The inclined surface is further used to guide the organic light-emitting material, so that the organic light-emitting material can smoothly flow into the interior of the purification bin 12. After the introduction of the organic light-emitting material is completed, the solenoid valve 10 inside the guide hole 19 is closed, and the auxiliary purification solvent is injected through the purification solvent injection port 11.
