Technical Field
[0001] The present application relates to the technical field of distillation tower cleaning, and in particular to an easy-to-clean distillation tower. Background Art
[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. By utilizing the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, the light components (low-boiling substances) in the liquid phase are transferred to the gas phase, and the heavy components (high-boiling substances) in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. The distillation tower is also a mass transfer and heat transfer device that is widely used in petrochemical production.
[0003] However, in actual use, some organic solvents will flow down along the inner wall of the distillation tower. Since some organic solvents contain high levels of solid impurities, the solid impurities often stick to the inner wall of the tower. They cannot be cleaned by simply flushing with a spray pipe, making cleaning very inconvenient.
[0004] Therefore, those skilled in the art provide a distillation tower that is easy to clean to solve the problems raised in the above background technology. Utility Model Content

[0021] Embodiment 1
[0022] Reference Figures 1 to 4As shown, the present application discloses an easy-to-clean distillation tower, comprising a tower body 1 and a base 11. A cleaning component 2 is arranged in the tower body 1, and the cleaning component 2 comprises a hollow disk 21 and a plurality of scrapers 22. The scrapers 22 are arranged in an inclined manner and fit with the inner wall of the tower body 1, and the plurality of scrapers 22 are arranged in a circular array on the hollow disk 21. In addition, three spirally arranged guide rods 23 are also arranged in the tower body 1. An inclined hole 25 is opened on the hollow disk 21, and the guide rod 23 is slidably sleeved in the inclined hole 25.
[0023] Specifically, a hollow disk 21 is disposed in the tower body 1, and a plurality of scrapers 22 are arranged in a circular array on the edge of the hollow disk 21. The outer edges of the scrapers 22 are inclined and fit against the inner wall of the tower body 1. In addition, a spirally arranged guide rod 23 is also mounted on the hollow disk 21. When the hollow disk 21 slides up and down, it rotates along the axial direction of the guide rod 23, thereby driving the scrapers 22 to continuously rotate on the inner wall of the tower body 1, making it convenient to scrape off impurities on the inner wall of the tower body 1 for cleaning.
[0024] Reference Figure 2 , Figure 3 , Figure 4 As shown, a shaft disk 26 is rotatably mounted at the center of the hollow disk 21, and an electric control push rod 27 is also mounted on the top inner wall of the tower body 1, and the output shaft of the electric control push rod 27 is connected to the center of the shaft disk 26;
[0025] Specifically, in order to facilitate the hollow disk 21 to maintain stable up and down sliding, an axis disk 26 is installed at the center of the hollow disk 21. The axis disk 26 can slide up and down conveniently with the cooperation of the electric control push rod 27. In addition, a plurality of bearing balls 28 are provided on the inner side wall of the hollow disk 21. The axis disk 26 is rotatably installed on the hollow disk 21 through the cooperation of the bearing balls 28. A plurality of leakage holes 29 are also penetrated on the hollow disk 21. With the cooperation of the bearing balls 28, the axis disk 26 can be kept rotatably connected with the hollow disk 21, so that when the axis disk 26 slides up and down, it does not affect the axial rotation of the hollow disk 21 along the guide rod 23.
[0026] Reference Figure 2 , Figure 3 As shown, the number of turns of the guide rod 23 is 0.5 to 1 turns, and mounting plates 24 are provided on both ends of the guide rod 23, and the mounting plates 24 are fixed on the inner wall of the tower body 1. In addition, three guide rods 23 are provided, which can stably support the hollow disk 21 and keep the hollow disk 21 able to push the scraper 22 to rotate to clean the inner wall of the tower body 1, and a funnel plate 3 is also provided in the tower body 1. After the cleaning component 2 scrapes off the impurities on the inner wall of the tower body 1, the spray system in the tower body 1 will flush the impurities into the funnel plate 3, which is convenient for centralized collection and treatment.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0029] The implementation principle of an easy-to-clean distillation tower in the present application is:
[0030] After the distillation tower is working, when solid impurities adhere to the inner wall of the tower body 1 and need to be cleaned, the electric control push rod 27 can be started to push the shaft disc 26 to slide downward, and the hollow disc 21 is installed on the outer ring of the shaft disc 26. In addition, bearing balls 28 are arranged on the inner wall of the hollow disc 21. With the cooperation of the bearing balls 28, the relative rotation between the hollow disc 21 and the shaft disc 26 can be maintained. In the process of the shaft disc 26 pushing the hollow disc 21 to slide up and down, the hollow disc 21 will rotate along the axial direction of the guide rod 23. Since the axial direction of the spirally arranged guide rod 23 is constantly changing, the hollow disc 21 can be continuously rotated, and since the scraper 22 is arranged at the edge of the hollow disc 21, the hollow disc 21 can be kept pushing multiple scrapers 22 to rotate continuously, so that the impurities on the inner wall of the tower body 1 can be cleaned, which is efficient and convenient.
[0031] In addition, a funnel plate 3 is also provided in the tower body 1. After the cleaning component 2 scrapes off the impurities on the inner wall of the tower body 1, the spray system in the tower body 1 will flush the impurities into the funnel plate 3, which is convenient for centralized collection and treatment.
