Description

Technical Field

[0001] The utility model relates to the technical field of chlorocyclohexane fractionation, in particular to a fractionation tower used for refining chlorocyclohexane. Background Art

[0002] Chlorocyclohexane is a chemical with the molecular formula C6H11Cl. It is a colorless liquid with a suffocating odor. It is insoluble in water but soluble in ethanol. It is used as a pharmaceutical intermediate and is used to prepare the anti-epileptic and anti-convulsant drug benzhexol hydrochloride. Chlorocyclohexane can be obtained by the cyclohexanol chlorination method. When using the cyclohexanol chlorination method to produce chlorocyclohexane, it needs to undergo a distillation operation, and can be produced using a traditional distillation tower.

[0003] After searching, it was found that the publication number is CN219897098U, and the name is a distillation tower. The application proposes that after the existing distillation tower is used, a lot of impurities will accumulate on the inner wall, which is inconvenient to clean the inner wall, and a lot of impurities will accumulate on the inner walls of multiple oil outlet pipes on one side of the distillation tower, which is difficult to clean. The half-face gear is driven by the starting motor to rotate, and then the L-shaped rod and the scraper are driven to rotate. When the detergent scraper rotates, the inner wall of the distillation tower body can be cleaned, and the L-shaped rod can wipe the bottom of the distillation tower body. When the half-face gear rotates, it will drive the gear ring to move back and forth, and then drive the cleaning rod to move back and forth. Movement, when the cleaning rod moves, it can be inserted into the oil outlet pipe to clean the inner wall of the oil outlet pipe. However, when the application is in use, if it is not rotated during distillation, the fraction cannot be stirred, and uneven heating is likely to occur, affecting the distillation efficiency. If it is rotated during distillation, although it can play a stirring role, it will aggravate the wear of the scraper and the inner wall of the distillation tower. The scraper is in contact with the inner wall of the distillation tower body for a long time, affecting the life of the distillation tower body. It is impossible to ensure the uniformity of heating while reducing wear, and further improvements can be made. At the same time, the application adopts a complex reciprocating gear meshing structure, the structure is relatively complex, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0015] Furthermore, the input end of the dual-purpose water pump for extraction and drainage is connected to the inside of the water tank through a water suction pipe.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a fractionation tower for refining chlorocyclohexane, which has the following beneficial effects:

[0018] (1) The utility model adopts a movable scraper. Chlorocyclohexane is fractionated inside the main body of the distillation tower. The fractionated components flow out along the oil outlet pipe. After the fractionation is completed, when it is necessary to clean the main body of the distillation tower, the driving motor and the dual-purpose water pump for pumping and discharging can be started to extract water from the water tank. The driving motor drives the driving gear to rotate, thereby driving the driven gear to rotate, thereby driving the main shaft pipe to rotate. The dual-purpose water pump for pumping and discharging draws water from the water tank through the water pipe and injects it into the main shaft pipe. The pressurized water enters the diversion pipe, pushing the piston to move, thereby pushing the scraper to abut against the inner wall of the main body of the distillation tower.

After cleaning, start the dual-purpose water pump to extract the water inside the main shaft pipe, reset the piston, and pull the scraper away from the main body of the distillation tower to avoid long-term scraping against the inner wall of the main body of the distillation tower and causing wear. This makes it easier for the main shaft pipe to rotate during distillation to drive the diverter pipe and the guide rod to rotate to stir the chlorocyclohexane fraction, thereby improving the uniformity of heating and the distillation efficiency. The device stirs during the distillation process to improve the uniformity of heating and the distillation efficiency. During the heating and stirring process, the scraper does not contact the main body of the distillation tower, thereby reducing wear and extending the service life. At the same time, the scraper can also scrape the inner wall of the main body of the distillation tower during the cleaning process, thereby improving the cleaning efficiency, enriching the use function, and improving work efficiency.

[0019] (2) The utility model adopts a nozzle and a nozzle. When water is injected into the main shaft pipe, a part of the pressurized water enters the nozzle and is sprayed out along the nozzle to spray water on the inner wall of the distillation tower body, thereby further improving the cleaning efficiency. At the same time, the nozzle and the oil outlet pipe are located at the same height. During the rotation of the nozzle, the nozzle can spray water into the inside of the oil outlet pipe for backwashing and simultaneously clean the inside of the oil outlet pipe. Compared with the complex gear reciprocating structure, the structure of the device is simpler and more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Working principle:

[0037] Chlorocyclohexane is fractionated inside the fractionation tower body 1, and the fractionated components flow out along the oil outlet pipe 2. After the fractionation is completed, when the fractionation tower body 1 needs to be cleaned, the driving motor 3 and the dual-use pump 15 can be started to extract water from the water tank 16. The driving motor 3 drives the driving gear 4 to rotate, and then drives the driven gear 6 to rotate, and then drives the main shaft pipe 5 to rotate. The dual-use pump 15 extracts water from the water tank 16 and injects it into the main shaft pipe 5 through the water pipe 11. The pressurized water enters the diversion pipe 9. In the process, the piston 12 is pushed to move, and then the scraper 10 is pushed to abut against the inner wall of the fractionation tower body 1. The inner wall of the fractionation tower body 1 is scraped and cleaned by the rotation of the scraper 10, which is convenient for cleaning the inner wall of the fractionation tower body 1 and improving the cleaning efficiency. After the cleaning is completed, the dual-purpose water pump 15 is started to extract the water inside the main shaft pipe 5, and the piston 12 is reset to pull the scraper 10 away from the fractionation tower body 1 to avoid long-term scraping with the inner wall of the fractionation tower body 1 and causing wear, so as to facilitate the rotation of the main shaft pipe 5 during fractionation. The diverter pipe 9 and the guide rod 14 are driven to rotate to stir the chlorocyclohexane fraction, thereby improving the uniformity of heating and the efficiency of fractionation. The device stirs during the fractionation process to improve the uniformity of heating and the efficiency of fractionation. During the heating and stirring process, the scraper 10 does not contact the distillation tower body 1, thereby reducing wear and extending the service life. At the same time, the scraper 10 can also scrape the inner wall of the distillation tower body 1 during the cleaning process to improve the cleaning efficiency, enrich the use function, and improve the work efficiency. At the same time, when the main shaft tube 5 is injected with water, a part of the pressure water enters the nozzle 19 and is sprayed along the nozzle 18 to spray and flush the inner wall of the distillation tower body 1, thereby further improving the cleaning efficiency. At the same time, the nozzle 19 is located at the same height as the oil outlet pipe 2. During the rotation of the nozzle 19, the nozzle 18 can spray water into the inside of the oil outlet pipe 2 for backwashing and synchronously cleaning the inside of the oil outlet pipe 2. Compared with the complex gear reciprocating structure, the device has a simpler structure and is more convenient to use.
