Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, and particularly relates to a molecular distillation device. Background Art

[0002] The molecular distillation process is a special liquid-liquid separation technology, which realizes the separation of substances by relying on the difference in the average free path of different molecules under vacuum conditions. Traditional molecular distillation devices generally include an outer shell, a scraper disposed inside the outer shell and abutting against the inner wall of the outer shell, and a motor for driving the scraper to rotate inside the outer shell. The motor controls the rotation of the scraper to scrape the liquid material on the inner wall of the outer shell into a thin film for heating and evaporation. However, the traditional scraper is usually a single piece, which will cause excess liquid to accumulate in front of the scraper, resulting in the unsmoothed liquid material flowing out through the outlet, and there is a problem of low liquid material separation efficiency. At the same time, when the liquid material processing is completed, the residual material will adhere to the inner wall of the outer shell. If not cleaned for a long time, the residual material will solidify, affecting the use of the molecular distillation device. Summary of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] As Figures 1 to 5 shown, the molecular distillation equipment of the present invention includes: a housing 1, a feed inlet 11 is formed at the top, a heavy oil outlet 12 is formed at the bottom side, a light oil outlet 13 is formed at the bottom, a heating device 14 is arranged outside the housing 1, and a first driving device 2 is arranged at the top of the housing 1; a material distribution plate 3, which is arranged above the inside of the housing 1 and is driven to rotate by the first driving device 2, the outer periphery of the material distribution plate 3 extends to the inner wall of the housing 1, and a condensation structure is arranged on the bottom surface of the material distribution plate 3; a central shaft 41 and a scraping cylinder 42, multiple groups of scraping cylinders 42 are arranged on the central shaft 41, the central shaft 41 is arranged on the bottom surface of the material distribution plate 3 and can move along the radial direction of the material distribution plate 3 to approach or move away from the housing 1; a scraper 5, which is arranged on the bottom surface of the material distribution plate 3 along the height direction, and the scraper 5 is configured to move along the radial direction of the material distribution plate 3 to fit or move away from the inner wall of the housing 1.

[0030] See Figure 1, the first driving device 2 can be a servo motor. The cross-section of the material distribution plate 3 is a circular structure. The center of the top surface of the material distribution plate 3 is connected to the rotating shaft of the servo motor. The outer peripheral side of the material distribution plate 3 is relatively close to the inner wall of the housing 1. When the first driving device 2 drives the material distribution plate 3 to rotate relative to the housing 1, the liquid material entering through the top feed port 11 can be evenly distributed on the inner wall of the housing 1, ensuring the fine division effect of the scraping cylinder 42 on the liquid material.

[0031] When extracting the liquid material, first, a heat source is introduced into the jacket. The heat source can be hot water or steam. Then, by controlling the central shaft 41 to move towards the inner wall of the housing 1, the scraping cylinder 42 is abutted against the inner wall of the housing 1, and the control scraper 5 is not in contact with the inner wall of the housing 1. Then, the liquid material is introduced into the housing 1 through the feed port 11. The first driving device 2 is used to control the rotation of the material distribution plate 3. The material distribution plate 3 drives the central shaft 41 and the scraping cylinder 42 to rotate. A plurality of scraping cylinders 42 arranged vertically on the central shaft 41 can scrape the liquid material flowing on the inner wall of the housing 1 into a thin film shape. The liquid material is heated by the heat source inside the jacket and can quickly evaporate and adhere to the condenser. The condensed light oil drips onto the bottom of the housing 1 through the condenser and is collected through the light oil outlet 13. The heavy oil on the inner wall of the housing 1 is discharged and collected through the heavy oil outlet 12 formed on the side of the housing 1.

[0032] After the extraction of the liquid material is completed, the central shaft 41 is controlled to move away from the inner wall of the housing 1 so that the scraping cylinder 42 is not in contact with the inner wall of the housing 1. At the same time, the control scraper 5 is attached to the inner wall of the housing 1. The first driving device 2 is used to control the rotation of the material distribution plate 3. The material distribution plate 3 drives the scraper 5 to rotate to scrape the residual material attached to the inner wall of the housing 1, preventing the residual material from being heated and dried and solidified on the inner wall of the housing 1 by the residual temperature of the heat source. Through this setting, the efficiency of liquid material processing can be effectively ensured, and the damage of the scraping cylinder 42 can be reduced, which has practicality.

[0033] In one or more embodiments, a power assembly for controlling the central shaft 41 and the scraper 5 to approach or move away from the inner wall of the housing 1 is installed on the housing 1 and the material distribution plate 3; the power assembly at least includes: a driving gear 61 and a driven gear 62, the driving gear 61 is engaged with the driven gear 62, the driven gear 62 is coaxial with the material distribution plate 3 and is arranged on the top surface of the material distribution plate 3, and the driving gear 61 is driven to rotate by the second driving device; a synchronous disk 63 and a transmission rod 64, the synchronous disk 63 is arranged on the bottom surface of the material distribution plate 3 and rotates synchronously with the driven gear 62. The synchronous disk 63 can rotate relative to the material distribution plate 3. The transmission rod 64 is rotatably installed on the bottom surface of the synchronous disk 63, and the other end of the transmission rod 64 is rotatably installed on the central shaft 41; a connecting rod 65 for connecting the central shaft 41 and the scraper 5; a waist-shaped hole is formed on the material distribution plate 3. The driven gear 62 and the synchronous disk 63 are connected by a rod body, and the rod body is located in the waist-shaped hole; the waist-shaped hole is blocked by the driven gear 62.

[0034] It should be noted that the second drive device can be a servo motor, which is configured outside the housing 1. The second drive device can control the rotation of the driving gear 61, and then rotate the driven gear 62 meshing with the driving gear 61, thereby realizing the rotation of the synchronization disk 63 and the transmission rod 64.

[0035] When the material liquid on the inner wall of the shell 1 is scraped into a thin film, the second driving device is used to control the driving gear 61 to rotate counterclockwise, and the driven gear 62 rotates clockwise relative to the driving gear 61. The driven gear 62 moves in the waist-shaped hole through the rod body to realize the rotation of the rod portion of the transmission rod 64, so that the other end of the transmission rod 64 drives the central axis 41 to move toward the inner wall of the shell 1, so that the scraper drum 42 is close to the inner wall of the shell 1. When the central axis 41 moves toward the inner wall of the shell 1, the central axis 41 drives the connecting rod 65 installed on the bottom surface of the material distribution plate 3 to rotate, so that the scraper 5 moves in the direction away from the inner wall of the shell 1; when the driven gear 62 and the synchronous disk 63 rotate, it is necessary to use the first driving device 2 to control the material distribution plate 3 to rotate, and the material distribution plate 3 rotates synchronously with the driven gear 62 and the synchronous disk 63, and the material distribution plate 3 drives the central axis 41 and the scraper drum 42 to rotate circumferentially to achieve the thinning of the material liquid on the inner wall of the shell 1.

[0036] When the scraper 5 is used to scrape off the residual material on the inner wall of the shell 1, the first driving device 2 is used to control the distribution plate 3 to rotate counterclockwise, and the second driving device is used to control the active gear 61 to rotate along the trend and the driven gear 62 to rotate counterclockwise, and the driven gear 62 drives the synchronous disk 63 to rotate counterclockwise, so that the transmission rod 64 pulls the middle axis 41 and the scraper cylinder 42 to move away from the inner wall of the shell 1, and the middle axis 41 controls the scraper 5 to move toward the inner wall of the shell 1 through the connecting rod 65 so that the scraper 5 abuts against the shell 1. At this time, the rotating scraper 5 can scrape off the residual material on the inner wall of the shell 1; it should be noted that when the distribution plate 3 drives the scraper 5 to rotate, it is necessary to use the second driving device to control the active gear 61 to rotate, so as to keep the driven gear 62 and the synchronous disk 63 rotating synchronously with the distribution plate 3.

[0037] In one or more embodiments, a plurality of scraper barrels 42 are detachably disposed on the central shaft 41. This arrangement can ensure the scraping effect of the residual material attached to the inner wall of the housing 1.

[0038] In one or more embodiments, a baffle 7 is disposed at the inner bottom of the shell 1 on the outer peripheral side of the central axis 41 and the condensation structure, and the baffle 7 is configured in an inclined structure, and the heavy oil outlet 12 is relatively located at the bottom end of the baffle 7. Figure 1 Through this arrangement, the heavy oil left on the inner wall of the shell 1 can be collected and concentrated, reducing the problem of mixing of heavy oil and light oil. At the same time, the heavy oil can flow out quickly through the heavy oil outlet 12, reducing the problem of heavy oil accumulation in the shell 1.

[0039] In one or more embodiments, the scraping cylinder 42 and the inner wall of the housing 1 are both sprayed with a PTFE coating. It should be noted that the PTFE coating has a certain self-lubricating effect. Through this setting, the flow rate of light oil and heavy oil can be effectively increased.

[0040] The above embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
