Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a clean distillation tower. Background Art

[0002] Distillation tower, the main function of the distillation tower is to separate mixed liquids. It uses the principle that different liquids have different volatility (boiling points) under different conditions, such as different temperatures, to separate liquids. During the distillation process, the vaporized liquid rises rapidly in the distillation tower, and the discharged steam is condensed through the condenser to achieve liquid separation, thereby achieving a purification effect. It is widely used in chemical industry, petrochemical industry, metallurgy, light industry, textile, alkali production, pharmaceuticals, pesticides, electroplating, electronics and other fields.

[0003] Patent No. CN221014522U discloses that a stirring mechanism is provided inside the tower body, and a brush head is fixedly provided at the end of the rotating rod of the stirring mechanism, so that the dirt layer on the inner wall of the tower body can be cleaned while stirring, thereby improving the heat exchange efficiency and distillation speed. When this patent is used, as the brush head cleans the inner wall, the front end of the brush head will gradually wear out. However, since the brush head and the end of the rotating rod are fixed, the brush head cannot fit tightly with the inner wall of the tower body for cleaning after the front end is worn, and the brush head can only be replaced. The brush head cannot be fully utilized, resulting in a great waste of the brush head. Especially when the workload is heavy, the brush head needs to be replaced in a short period of time, which greatly increases the cost of use. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a clean distillation tower with a durable scraper structure, which can improve the utilization rate of the scraper, reduce the cost of use, and improve the cleaning effect of the inner wall of the tower body. The dirt layer on the inner wall of the tower body is cleaned by a brush head, thereby improving the heat exchange efficiency and distillation speed of the distillation tower.

[0005] The utility model is realized through the following technical solution: a clean distillation tower, comprising a tower body, wherein a rotating shaft is rotatably connected to the tower body, a driving motor for driving the rotating shaft is provided on the tower body, and a scraper is connected to the outer wall of the rotating shaft through a propulsion assembly, and the propulsion assembly pushes the scraper to move in a direction away from the rotating shaft and contact the inner wall of the tower body.

[0006] In this solution, the propulsion assembly propels the scraper away from the rotating shaft. As the front end of the scraper gradually wears, the propulsion assembly ensures that the scraper maintains contact with the tower inner wall, ensuring a close fit and sweeping away dirt. This improves the cleaning effect of the tower inner wall and also provides a stirring effect, increasing the heat exchange efficiency and distillation speed of the distillation tower. Furthermore, the propulsion assembly allows the scraper to be replaced only after the scraping surface is completely worn, thereby improving scraper utilization, reducing operating costs, and extending the service life of the scraper.

[0007] As an optimization, the propulsion assembly includes a fixed rod and a movable member. One end of the fixed rod is fixedly connected to the outer wall of the rotating shaft, and the other end is slidably connected to the movable member. The fixed rod is equipped with a spring to push the movable member away from the rotating shaft. The end of the movable member away from the fixed rod is detachably connected to the scraper. This optimization solution uses the spring's elasticity to push the movable member away from the rotating shaft, ensuring that the scraper maintains a tight fit against the inner wall of the tower body as it wears. The scraper and movable member are detachably connected, making it easy to replace the scraper.

[0008] As an optimization, the fixed rod is provided with a transversely extending sliding hole, and the movable member is provided with a sliding rod adapted to the sliding hole. The sliding rod passes through the sliding hole and slides along the sliding hole. The spring is located within the sliding hole and on the side of the sliding rod closest to the rotating shaft. One end of the spring is fixedly connected to the inner wall of the sliding hole, and the other end of the spring is fixedly connected to the sliding rod. In this optimized solution, the movable member and the fixed rod are slidably connected through the sliding rod and the sliding hole. The spring is located on the side of the sliding rod closest to the rotating shaft, thereby pushing the sliding rod to slide away from the rotating shaft, causing the scraper to contact the inner wall of the tower body.

[0009] As an optimization, the tower body is topped with a top cover, the bottom of which and the top of the tower body are both fixed with flanges, and the two flanges are connected by bolts. In this optimization solution, the top cover is screwed to the tower body and is removable to facilitate inspection and maintenance of the tower body and replacement of scrapers.

[0010] As an optimization, a spray pipe is provided inside the top cover, which is fixed to the inner wall of the top cover via a support plate. This optimization solution facilitates flushing of the inner wall of the tower body through the spray pipe, and the scraper can better clean the dirt layer on the inner wall of the tower body.

[0011] As an optimization, the outer wall of the tower body is provided with an insulation layer and a heating coil, and the heating coil is located inside the insulation layer. This optimization solution heats the material inside the tower body through the heating coil, and the insulation layer is provided to reduce heat loss and improve the heating effect.

[0012] The beneficial effects of the present invention are as follows: the propulsion assembly pushes the scraper to move away from the rotating shaft. As the front end of the scraper gradually wears, the propulsion assembly pushes the scraper to always contact the inner wall of the tower body, so that the scraper always fits tightly with the inner wall of the tower body to clean dirt, improving the cleaning effect of the inner wall of the tower body, and improving the heat exchange efficiency and distillation speed of the distillation tower. At the same time, the propulsion assembly pushes the scraper to be replaced after the scraping surface is completely worn, thereby improving the utilization rate of the scraper, reducing the cost of use, and extending the service life of the scraper. The tower body is equipped with a removable top cover to facilitate inspection and maintenance of the interior of the tower body, and also to facilitate replacement of the scraper. The spray pipe facilitates flushing of the inner wall of the tower body, and the scraping of the scraper has a better cleaning effect on the dirt layer on the inner wall of the tower body. The material inside the tower body is heated by the heating coil, and the provision of an insulation layer reduces heat loss and improves the heating effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0023] like Figures 1 to 7 As shown, a clean distillation tower comprises a tower body 1, with a top cover 6 disposed on top of the tower body 1. Flanges 10 are secured to the bottom of the top cover 6 and the top of the tower body 1, and the two flanges 10 are bolted together. In this embodiment, a feed inlet 11 is provided on the sidewall of the tower body 1, a discharge port 12 is disposed at the bottom of the tower body 1, and an exhaust port 13 is disposed at the top of the top cover 6.

[0024] A rotating shaft 2 is rotatably connected within the tower body 1, and a drive motor 3 is mounted on the tower body 1 to drive the rotating shaft 2. In this embodiment, the rotating shaft 2 extends vertically, with its bottom rotatably connected to the bottom of the tower body 1. The drive motor 3 is fixed to the bottom of the tower body 1, and the output end of the drive motor 3 is fixedly connected to the lower end of the rotating shaft 2 via a coupling, thereby driving the rotation of the rotating shaft.

[0025] The outer wall of the rotating shaft 2 is connected to a scraper 5 via a propulsion assembly 4. This propulsion assembly 4 propels the scraper 5 away from the rotating shaft 2 and into contact with the inner wall of the tower body 1. In this embodiment, a scraper 5 is provided on each side of the rotating shaft 2. These scrapers 5 extend vertically and are symmetrically distributed along the axis of the rotating shaft 2. Two propulsion assemblies 4 are located between the scraper 5 and the rotating shaft 2, enhancing the stability of the connection between the rotating shaft and the scraper.

[0026] The propulsion assembly 4 includes a fixed rod 41 and a movable part 42. One end of the fixed rod 41 is fixedly connected to the outer wall of the rotating shaft 2, and the other end of the fixed rod 41 is slidably connected to the movable part 42. The fixed rod 41 is provided with a spring 43 that pushes the movable part 42 to slide away from the rotating shaft 2. The end of the movable part 42 away from the fixed rod 41 is detachably fixed to the scraper 5.

[0027] Specifically, the fixed rod 41 is provided with a transversely extending sliding hole 411, and the movable part 42 is provided with a sliding rod 422 adapted to the sliding hole 411. The sliding rod 422 passes through the sliding hole 411 and slides along the sliding hole. The spring 43 is located in the sliding hole 411 and on the side of the sliding rod close to the rotating shaft. One end of the spring 43 is fixedly connected to the inner wall of the sliding hole 411, and the other end of the spring 43 is fixedly connected to the sliding rod 422.

[0028] In this embodiment, the fixed rod 41 extends horizontally, and the sliding hole 411 extends along the length of the fixed rod 41. The movable member 42 includes a connecting block 421 and a sliding rod 422. The connecting block 421 has a slot 4211 at one end near the fixed rod 41, and a socket 4212 is formed on the side wall of the connecting block 421, which communicates with the slot 4211. The end of the fixed rod 41 is inserted into the slot 4211, and the sliding rod 422 passes through the socket 4212 and the sliding hole 411 of the fixed rod, thereby achieving a sliding connection between the movable member 42 and the fixed rod 41. The sliding rod 422 has a rectangular cross-section, which maintains the sliding stability of the connecting block. The sliding rod 422 is pierced with two pins 423, which are located on either side of the connecting block 421. The sliding rod 422 and the connecting block 421 are fixed together by the two pins 423, thereby achieving a removable connection between the sliding rod 422 and the connecting block 421, facilitating the installation and connection of the connecting block and the fixed rod. In this embodiment, the scraper 5 is fixed to the end of the connecting block 421 away from the fixing rod 41 by bolts.

[0029] In this embodiment, the spring 43 extends along the length of the slide hole 411. Fixing posts are fixed to the inner wall of the slide hole 411 and the side wall of the slide rod 422. The two fixing posts are positioned opposite each other, and the ends of the spring are respectively inserted and fixed to the two fixing posts. A sliding margin is left between the side of the slide rod 422 away from the spring 43 and the inner wall of the slide hole. When the scraper 5 contacts the inner wall of the tower body 1, the spring 43 is in a compressed state, thereby elastically pushing the slide rod 422 to slide away from the rotating shaft 2.

[0030] The top cover 6 is provided with a spray pipe 7, which is fixed to the inner wall of the top cover 6 via a support plate. In this embodiment, the spray pipe 7 is annular, and the outer diameter of the spray pipe is adapted to the inner diameter of the top cover. The spray head at the bottom of the spray pipe is arranged facing the inner wall of the tower body.

[0031] The outer wall of the tower body 1 is provided with an insulation layer 9 and a heating coil 8. The heating coil 8 is located in the insulation layer 9 and is fixed around the outer wall of the tower body. The insulation layer 9 is insulation cotton.

[0032] Working Principle: Drive motor 3 rotates shaft 2, causing scraper 5 to clean the inner wall of tower body 1 and simultaneously stir the material inside. As the front end of scraper 5 gradually wears, compressed spring 43 elastically pushes movable member 42 away from shaft 2, ensuring that scraper 5 maintains close contact with the inner wall of tower body 1, cleaning dirt. Spray pipe 7 allows for regular flushing of the inner wall of tower body 1, enhancing cleaning efficiency.
