Technical Field

[0001] This invention belongs to the field of carbazole purification technology, specifically a crystallizer for carbazole purification. Background Technology

[0002] Carbazole is one of the most economically valuable components of coal tar and an important intermediate in the synthesis of fine chemicals. It can be used in the production of fuels, pigments, pesticides, pharmaceuticals, optoelectronic materials, specialty inks, and synthetic resins. With the development of fine chemicals and the advancement of organic synthesis technology, the demand for high-purity carbazole is increasing. Higher purity leads to stronger market competitiveness and greater economic benefits. Currently, carbazole purification mainly uses crystallization. However, the crystallization process involves a chemical reaction that produces toxic gases. Directly releasing these gases could harm workers' health and pollute the air. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a crystallizer for carbazole purification, which solves the problem that carbazole produces a chemical reaction during crystallization, which generates toxic gases. Directly releasing these gases into the environment would affect the health of workers and also pollute the air.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crystallizer for carbazole purification, comprising a base, a slide rail on the top of the base, a connecting plate fixedly connected to the top of the base, the connecting plate being disposed on the outer side of the top of the slide rail, a reaction tank being slidably connected inside the slide rail, the reaction tank being disposed on the inner side of the connecting plate, electric telescopic rods fixedly connected to both ends of the outer side of the connecting plate, a top plate fixedly connected to the top of the electric telescopic rods, a top cover fixedly connected to the bottom of the top plate, the top cover being fitted onto the outer side of the reaction tank, and a limiting block fixedly connected to the top of the top of the top cover, the limiting block fitting into the reaction tank.

[0005] As a further embodiment of this utility model: the top of the base is fixedly connected to three fixing seats, and the top of the fixing seats is provided with limiting holes.

[0006] As a further embodiment of this utility model: two fixing seats are fixedly connected to one side of the connecting plate, and a gas storage bottle and a liquid storage bottle are respectively provided in the limiting holes in the two fixing seats, and a connecting pipe is provided on the top side of the liquid storage bottle.

[0007] As a further embodiment of this utility model: the other end of the connecting pipe is connected to the top side of the gas storage bottle, the top side of the liquid storage bottle is provided with a collection pipe, the other end of the collection pipe passes through the top plate, the top cover and the limiting block, and another fixing seat is fixedly connected to the other side of the connecting plate.

[0008] As a further embodiment of this utility model: an exhaust bottle is provided in the limiting hole in the fixed base, the liquid storage bottle and the exhaust bottle are provided with filtered liquid inside, and an exhaust hole is provided on one side of the top of the gas storage bottle and the exhaust bottle.

[0009] As a further embodiment of this utility model: an exhaust pipe is provided on one side of the top of the exhaust bottle, and the other end of the exhaust pipe passes through the top plate and the top cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This crystallizer for carbazole purification, equipped with an electric telescopic rod, top plate, top cover, collection pipe, and exhaust pipe, allows for convenient purification and crystallization of carbazole. First, the electric telescopic rod moves upward, causing the top plate to move upward. The top plate then moves the top cover, collection pipe, and exhaust pipe upward. The top cover moves the limiting block upward, separating the reaction vessel inside the top cover from the top cover itself. Next, the top cover moves outward along the slide rail at the top of the base. Carbazole and reactants are then placed into the reaction vessel. The reaction vessel is then pushed along the slide rail to the bottom of the top cover for reaction. Finally, the electric telescopic rod moves downward, causing the top plate, top cover, collection pipe, and exhaust pipe to move downward. The top cover moves the limiting block downward, ensuring it fully engages with the top of the reaction vessel, thus purifying and crystallizing the carbazole. This provides convenience for workers during carbazole purification and crystallization, prevents the direct emission of toxic gases during the reaction process, and protects the health of workers. 2. This crystallizer for carbazole purification consists of a gas storage bottle, a filter liquid, an exhaust port, a liquid storage bottle, and an exhaust bottle. When carbazole is being purified and crystallized, the gas storage bottle, the liquid storage bottle filled with the filter liquid, and the exhaust bottle are first placed in a fixed base. Then, the gas from the carbazole purification and crystallization reaction is discharged from the collection pipe and the exhaust pipe into the liquid storage bottle and the exhaust bottle, where it reacts with the filter liquid. This reacts with the filter liquid and is then discharged into the gas storage bottle. The filtered toxic gas is then discharged through the exhaust port at the top of the gas storage bottle and the exhaust bottle. Simultaneously, the filtered gas can be collected in the gas storage bottle, thus preventing the toxic gas from polluting the air during the reaction process. Attached Figure Description

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a crystallizer for carbazole purification, including a base 1, three fixed seats 12 are fixedly connected to the top of the base 1, and the top of the fixed seats 12 is provided with limiting holes 13. By setting the fixed seats 12 and the limiting holes 13, the exhaust bottle 11, the liquid storage bottle 14 and the gas storage bottle 16 can be fixed and limited to prevent them from being misaligned due to collision, thereby affecting their working efficiency. The top of the base 1 is provided with a slide 2, and a connecting plate 3 is fixedly connected to the top of the base 1. The connecting plate 3 is located on the outer side of the top of the slide 2. Two fixed seats 12 are fixedly connected to one side of the connecting plate 3. A gas storage bottle 16 and a liquid storage bottle 14 are respectively provided in the limiting holes 13 in the two fixed seats 12. A connecting pipe 17 is provided on the top side of the liquid storage bottle 14. By setting the connecting pipe 17, the filtered reaction gas can be introduced into the gas storage bottle 16 through the connecting pipe 17. The slide 2 is internally connected to a reaction tank 4, which is located inside the connecting plate 3. The two ends of the outer side of the connecting plate 3 are fixedly connected to an electric telescopic rod 5. The top of the electric telescopic rod 5 is fixedly connected to a top plate 6, and the bottom of the top plate 6 is fixedly connected to a top cover 7. The other end of the connecting pipe 17 is connected to the top side of the gas storage bottle 16. The top side of the liquid storage bottle 14 is provided with a collection pipe 9. The other end of the collection pipe 9 passes through the top plate 6, the top cover 7, and the limiting block 8. Another fixed seat 12 is fixedly connected to the other side of the connecting plate 3. By setting the limiting block 8, the limiting block 8 can fit with the reaction tank 4 to form a sealed space, preventing the toxic gas generated during the purification and crystallization of carbazole from leaking out. The top cover 7 is fitted onto the outside of the reaction vessel 4. A limiting block 8 is fixedly connected to the top of the top cover 7, and the limiting block 8 fits into the reaction vessel 4. An exhaust bottle 11 is provided in the limiting hole 13 in the fixing seat 12. The liquid storage bottle 14 and the exhaust bottle 11 are provided with filter liquid 15. An exhaust hole 18 is provided on one side of the top of the gas storage bottle 16 and the exhaust bottle 11. By providing filter liquid 15, the toxic gas generated during the purification and crystallization of carbazole can be filtered through the filter liquid 15. The top side of the exhaust bottle 11 is provided with an exhaust pipe 10, and the other end of the exhaust pipe 10 passes through the top plate 6 and the top cover 7. By setting the exhaust pipe 10, the toxic gas between the reaction tank 4 and the top cover 7 can be discharged into the exhaust bottle 11 for filtration through the exhaust pipe 10.

[0014] The working principle of this utility model is as follows: When it is necessary to purify and crystallize carbazole, firstly, the electric telescopic rod 5 is moved upward, causing the electric telescopic rod 5 to drive the top plate 6 upward. The top plate 6 then drives the top cover 7, the collecting pipe 9, and the exhaust pipe 10 upward. The top cover 7 drives the limiting block 8 upward, thereby separating the reaction barrel 4 inside the top cover 7 from the top cover 7. Then, the top cover 7 is moved outward along the slide 2 at the top of the base 1. Carbazole and the reaction raw materials are then placed into the reaction barrel 4. The reaction barrel 4 is then pushed along the slide 2 to the bottom of the top cover 7 for reaction. Finally, the electric telescopic rod 5 is moved downward, causing the top plate 6 to drive the top cover 7 upward. The top cover 7, collecting pipe 9, and exhaust pipe 10 move downwards, and the top cover 7 drives the limiting block 8 to move downwards, so that the limiting block 8 is completely fitted with the top of the reaction tank 4, so that carbazole can be purified and crystallized. The gas storage bottle 16, the liquid storage bottle 14 filled with filtered liquid 15, and the exhaust bottle 11 are placed in the fixed seat 12. Then, the gas from the carbazole purification and crystallization reaction is discharged from the collecting pipe 9 and the exhaust pipe 10 into the liquid storage bottle 14 and the exhaust bottle 11, and then reacts with the filtered liquid 15, and then discharged into the gas storage bottle 16. Finally, the filtered toxic gas is discharged through the exhaust hole 18 at the top of the gas storage bottle 16 and the exhaust bottle 11.
