Description

Technical Field

[0001] The utility model relates to the technical field of carbazole processing, in particular to a carbazole purification device. Background Art

[0002] Carbazole is a nitrogen-containing heterocyclic compound, also known as 9-nitrogen (hetero)fluorene (dibenzopyrrole), with a molecular formula of C12H9N. It is one of the most economically valuable components in coal tar. 90% of the world's carbazole is obtained from coal tar. Carbazole can be used to produce dyes, pigments, photoconductors, photosensitive materials, special inks, etc. The pigment Permanent Violet RL produced with it is widely used in the coloring of automotive topcoats and high-temperature resistant plastics, and has the advantages of high temperature resistance and UV resistance.

[0003] At present, the main technologies for refining carbazole include solvent method, chemical separation method, zone melting method and emulsion liquid membrane method. Among them, the solvent method is the most mature and industrialized main method, including solvent washing method, crystallization-distillation method and distillation-solvent method. The solvent washing method is the most widely used method. It uses the different solubilities of anthracene, phenanthrene and carbazole in a certain solvent for separation, and can extract anthracene and carbazole from crude anthracene. After the carbazole is separated, the solvent will remain in the raw material, affecting the purity and quality of the raw material. During use, the existing carbazole purification device is not convenient for screening the separated carbazole raw material, so that large particles and impurities are mixed in the raw material, reducing the quality of subsequent processing. When the carbazole raw material is dried, a dryer is usually used to dry it. However, when the above scheme is used, while the water in the carbazole raw material evaporates quickly and becomes dry, it is not convenient to control the temperature in the barrel, resulting in excessive temperature and damage to the quality of the carbazole raw material, reducing the quality of the carbazole raw material after drying.

By setting the rotating block 222, it is convenient to support the sieve plate 24. Therefore, the rotation of the rotating block 222 will drive the sieve plate 24 to reciprocate in the vertical direction on the guide rod 23. The up and down vibration of the sieve plate 24 will drive the continuous movement of the carbazole raw material on the top of it. The carbazole raw material will fall through the holes and grooves on the sieve plate 24 during the vibration process, which can effectively screen the carbazole raw material, remove impurities from the raw material, and improve the quality of subsequent processing.

[0025] refer to Figure 1 , Figure 2 and Figure 5 As shown, the washing component 4 includes a second driving member 41 arranged inside the shell 6, a slider 42 fixed to one side of the second driving member 41, and a slide rod 43 sliding on the inner side of the slider 42; the second driving member 41 includes a third motor 411 fixed to one side of the shell 6, a bidirectional screw 412 fixed to the output end of the third motor 411, and a moving block 413 threadedly connected to the outer side of the bidirectional screw 412; by setting the third motor 411 and the bidirectional screw 412, it is convenient to drive the moving block 413 to move, and by setting the slide rod 43, it is convenient for the slider 42 to slide following the moving block 413, and when the moving block 413 and the slider 42 move, the nozzle 54 evenly rinses the carbazole raw material, removes the residual separation solution, improves the cleaning effect, and improves the purity of the carbazole raw material.

[0026] refer to Figure 1 and Figure 2 As shown, the water supply component 5 includes a water tank 51 fixed on the top of the fixed plate 1, a water pump 52 connected to the inside of the water tank 51, a connecting pipe 53 connected to the water outlet of the water pump 52, and a nozzle 54 connected to one end of the connecting pipe 53; the connecting pipe 53 is composed of a main pipe and a branch pipe, one end of the main pipe is connected to the water outlet of the water pump 52, one end of the branch pipe is connected to the main pipe, and the other end of the branch pipe is connected to the nozzle 54. The branch pipe is made of a hose material, which is convenient for the nozzle 54 to move with the moving block 413. By setting the water supply component 5, it is convenient to provide cleaning liquid to the washing component 4. After washing the separated carbazole, the separation solution remaining in the raw material is effectively removed, thereby improving the purity of the raw material.

[0027] Working principle: When in use, first, the carbazole raw material is injected into the device from the feed port 7 on the top of the shell 6. At this time, the water pump 52 in the water supply component 5 draws cleaning liquid from the water tank 51 and transports it to the nozzle 54 through the connecting pipe 53. The third motor 411 drives the bidirectional screw 412 to rotate, so that the moving block 413 moves on the bidirectional screw 412. The movement of the moving block 413 drives the slider 42 and the slider 43 to move synchronously, so that the nozzle 54 can evenly rinse the carbazole raw material, wash the carbazole raw material, remove the residual separation solution, and thus improve its purity. At the same time, the screening mechanism 2 starts to work, and the first motor 211 drives the rotating rod 214 to rotate, thereby driving the first bevel gear 212 to rotate. The meshing of the first bevel gear 212 and the second bevel gear 213 causes the second bevel gear 213 and the connecting rod 221 to rotate synchronously, so that the rotating block 222 at the other end of the connecting rod 221 rotates, thereby driving the sieve plate 24 along the guide rod 23. The sieve plate 24 reciprocates in the vertical direction, and the up and down vibration of the sieve plate 24 drives the carbazole raw material on the top thereof to move continuously. The raw material falls through the holes and grooves on the sieve plate 24 during the vibration process, thereby screening the carbazole raw material and removing large particles and impurities from the raw material to ensure the quality of subsequent processing. Subsequently, the cleaning liquid is discharged from the drain pipe 9, and the carbazole raw material enters the storage barrel 31 through the opening of the electromagnetic valve arranged inside the injection pipe 8. Then the second motor 321 drives the rotating shaft 322 to rotate, thereby driving the stirring plate 323 to rotate inside the storage barrel 31 to turn the raw material over, so that it can be dried faster and more evenly. At the same time, the hot air blower 332 and the cold air blower 333 in the blowing member 33 work according to the temperature detected by the temperature sensor 331 to control the temperature in the barrel to prevent the temperature from being too high to damage the quality of the raw material. After stirring and blowing drying, the quality of the dried carbazole raw material is guaranteed, the effective purification of the carbazole raw material is achieved, and its purity is improved, providing high-quality raw materials for subsequent processing.
