Description

Technical Field

[0001] This utility model relates to the field of rotary evaporator cleaning technology, specifically to a cleaning device for rotary evaporator flasks. Background Technology

[0002] A rotary evaporator, also known as a rotary evaporator, is a widely used evaporation instrument in laboratories. It consists of a rotary motor, evaporation tubes, a vacuum system, a heating pan, and a condenser. It is primarily used for solvent recovery and evaporation under reduced pressure. However, during use, as the solution (e.g., a pharmaceutical solution) evaporates, the density of the solution increases, and the thick paste adheres to the inner wall of the rotating flask. This makes collecting the concentrated solution and cleaning the flask difficult, requiring either reaching into the flask to collect the solution or using a cleaning brush. These methods are ineffective and increase the workload for laboratory personnel. Therefore, there is an urgent need to design a cleaning device for rotary evaporation flasks to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to be able to clean and scrape the inside of the evaporation bottle during or after evaporation, reducing the adhesion of thick paste to the inner wall of the evaporation bottle, making it easier and more thorough to pour out the medicine, and making it easier to clean the inside of the evaporation bottle.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a cleaning device for a rotary evaporator, comprising: an evaporation base, a stand, a magnetic suction assembly, and a cleaning and scraping assembly;

[0005] The stand is located on one side of the evaporation base, which is used to place the rotary evaporation flask for evaporation.

[0006] The magnetic suction assembly includes a rotating frame rotatably connected to a vertical frame. The rotating frame is provided with a magnetic suction ring that matches the rotary evaporator. An external air bladder is provided on the center side of the magnetic suction ring. An external magnetic strip is provided on the external air bladder. A magnetic suction ring air pump is provided on the outside of the magnetic suction ring. The magnetic suction ring air pump is connected to the external air bladder. A drive mechanism for driving the rotary evaporator to rotate is provided on the magnetic suction ring.

[0007] The cleaning assembly includes a scraping mechanism located inside the rotary evaporator and matched with an external magnetic strip, as well as a limiting mechanism for limiting the scraping mechanism.

[0008] As a preferred embodiment of the present invention, the driving mechanism includes a driving motor, which is disposed in a magnetic ring, and the output end of the driving motor is connected to a driving shaft, which is connected to a driving roller.

[0009] By adopting the above technical solution, the drive motor drives the drive roller to rotate through the drive shaft. As the drive roller rotates, when the rotary evaporator is placed in the magnetic ring, the drive roller comes into contact with the rotary evaporator. As the drive roller rotates, it drives the rotary evaporator to rotate.

[0010] As a preferred technical solution of this utility model, the scraping mechanism includes two straight strips, the ends of which are connected to an arc-shaped plate. An internal airbag matching the external airbag is provided on the arc-shaped plate. An internal magnetic strip matching the external magnetic strip is provided inside the internal airbag. A cleaning scraping strip is provided outside the internal airbag.

[0011] By adopting the above technical solution, and by setting up straight strips and curved plates, it is convenient to insert straight strips and curved plates into the interior of the rotary evaporator. By setting up an internal air bladder and inflating it, the inflated internal air bladder can make the cleaning strips contact and adhere to the inner wall of the rotary evaporator, ensuring the subsequent cleaning effect. At the same time, the inflated internal air bladder can make the internal magnetic strips close to the inner wall of the rotary evaporator, so that the internal magnetic strips can better cooperate with the external magnetic strips.

[0012] As a preferred embodiment of this utility model, the straight bar is equipped with a straight bar air pump and a removable battery. The straight bar air pump is connected to the internal airbag, and the straight bar air pump is equipped with an internal wireless repeater. The removable battery is electrically connected to the straight bar air pump and the internal wireless repeater respectively.

[0013] By adopting the above technical solution and by setting a removable battery, power is provided to the straight air pump and the internal wireless repeater. The straight air pump facilitates the inflation and deflation of the internal airbags.

[0014] As a preferred technical solution of this utility model, the limiting mechanism includes a bottle cap that can be detachably installed on the mouth of the rotary evaporator, a sliding limiting post disposed at the end of the straight bar away from the arc plate, a limiting frame disposed on the end of the two straight bars near the sliding limiting post, and a limiting bolt threaded to the limiting frame of the two straight bars for limiting the position of the two straight bars. The bottle cap has an annular sliding groove, and the sliding limiting post can be slidably connected in the sliding groove.

[0015] By adopting the above technical solution, a bottle cap is set for installation at the mouth of the rotary evaporator, a sliding groove is used to limit the sliding limit post, and a limit bolt is used to restrict the position of the two straight bars so as to ensure that the sliding limit post can be slidably connected in the sliding groove. Since the bottle cap limits the straight bars, it plays a certain limiting role on the arc plate, so that the arc plate can move more smoothly.

[0016] As a preferred technical solution of this utility model, the support frame is provided with an operation panel and an external wireless repeater. The operation panel is electrically connected to the magnetic ring air pump and the external wireless repeater respectively. The external wireless repeater and the internal wireless repeater interact with each other through wireless signals.

[0017] By adopting the above technical solution and setting up an operation panel, the magnetic ring air pump can be easily controlled. With the help of an external wireless repeater and an internal wireless repeater, the straight air pump can be easily controlled via the operation panel.

[0018] The beneficial effects of this utility model are reflected in:

[0019] 1. By setting up a cleaning assembly, straight strips and curved plates are placed in the rotary evaporator flask. A limiting mechanism restricts the position of the strips and curved plates. The evaporator base supports the rotary evaporator flask, which is then positioned within a magnetic ring. An air pump inflates the external airbag, clamping the flask and attaching the external magnetic strip to the outer wall of the flask. This external airbag inflation method ensures compatibility with rotary evaporators of different curved surfaces. A separate air pump inflates the internal airbag, causing the cleaning strip to adhere to the inner wall of the flask, with the internal magnetic strip positioned close to the inner wall. This ensures that the internal and external magnetic strips correspond and attract each other. This internal airbag inflation method also ensures compatibility with rotary evaporators of different curved surfaces. The evaporation flask is adapted so that the internal and external magnetic strips attract each other. After the cleaning strip adheres to the inner wall of the rotary evaporation flask, a drive mechanism rotates the evaporation flask. The rotating evaporation flask causes the arc-shaped plate of the cleaning strip to rotate relative to the evaporation flask, thus enabling the cleaning strip to rotate relative to the evaporation flask for cleaning the inside. In this way, during the evaporation process, the inside of the rotary evaporation flask is cleaned, reducing the amount of thick paste adhering to the inner wall of the evaporation flask. When it is necessary to remove the medicine, the medicine inside the rotary evaporation flask and the medicine on the arc-shaped plate can be removed separately, making it easier and more thorough to remove the medicine from the rotary evaporation flask. During the cleaning process, the cleaning strip can better clean the inside of the rotary evaporation flask. Attached Figure Description

Detailed Implementation

[0028] Based on the applicant's research and analysis, a rotary evaporator, also known as a rotary evaporator, is a widely used evaporation instrument in laboratories. It consists of a rotary motor, evaporation tubes, a vacuum system, a heating pan, and a condenser, and is mainly used for solvent recovery and evaporation under reduced pressure. However, during use, as the solution (e.g., a pharmaceutical solution) evaporates, the density of the solution increases, and a thick paste adheres to the inner wall of the rotating flask. This makes collecting the concentrated solution and cleaning the flask difficult, requiring either reaching into the flask to collect the solution or using a cleaning brush. This method is neither thorough nor efficient, and it increases the workload for laboratory personnel. Therefore, there is an urgent need to design a cleaning device for rotary evaporation flasks that can scrape the inside of the flask during or after evaporation, reducing the amount of thick paste adhering to the inner wall. This would allow for easier and more thorough removal of the solution and easier cleaning of the inside of the flask.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figure 1-7As shown, a cleaning device for a rotary evaporator includes an evaporator base 1, a stand 2, a rotating frame 3, a magnetic ring 4, an external air bladder 5, an external magnetic strip 51, a magnetic ring air pump 52, a straight bar 6, a sliding limit post 7, a limit frame body 8, an arc plate 9, an internal air bladder 10, a cleaning scraper 101, an internal magnetic strip 102, a straight bar air pump 103, a removable battery 104, an internal wireless repeater 105, a limit bolt 11, a bottle cap 12, a sliding groove 13, a drive motor 14, a drive shaft 15, a drive roller 16, an operation panel 17, and a wireless repeater 18.

[0031] Combined with appendix Figure 1-7As shown, a cleaning device for a rotary evaporator flask includes: an evaporator base 1, a stand 2, a magnetic suction assembly, and a scraping assembly. The stand 2 is located on one side of the evaporator base 1, which is used to place the rotary evaporator flask for evaporation. The magnetic suction assembly includes a rotating frame 3, which is rotatably connected to the stand 2. The rotating frame 3 is provided with a magnetic suction ring 4 that matches the rotary evaporator flask. An external air bladder 5 is provided on the center side of the magnetic suction ring 4, and an external magnetic strip 51 is provided on the external air bladder 5. A magnetic suction ring air pump 52 is provided on the outside of the magnetic suction ring 4 and is connected to the external air bladder 5. The magnetic suction ring 4 is provided with a drive mechanism for rotating the rotary evaporator flask. The scraping assembly includes... The system includes a scraping mechanism located inside a rotary evaporator flask and matched with an external magnetic strip 51, and a limiting mechanism for limiting the scraping mechanism. The scraping mechanism comprises two straight strips 6, each with an arc-shaped plate 9 at its end. An internal airbag 10, matched with an external airbag 5, is mounted on the arc-shaped plate 9. An internal magnetic strip 102, matched with the external magnetic strip 51, is located inside the internal airbag 10. A cleaning scraping strip 101 is located outside the internal airbag 10. A straight strip air pump 103 and a removable battery 104 are mounted on each straight strip 6. The straight strip air pump 103 is connected to the internal airbag 10 and has an internal wireless repeater 105. The removable battery 104 is connected to the straight strip air pump 103 and the internal airbag 104. An internal wireless repeater 105 is electrically connected. An operation panel 17 and an external wireless repeater 18 are mounted on the support frame 2. The operation panel 17 is electrically connected to both the magnetic ring air pump 52 and the external wireless repeater 18. The external wireless repeater 18 interacts with the internal wireless repeater 105 via wireless signals. By setting up a cleaning assembly, straight strips 6 and curved plates 9 are placed in the rotary evaporator flask. A limiting mechanism restricts the positions of the straight strips 6 and curved plates 9. The evaporator base 1 supports the rotary evaporator flask, ensuring it is positioned within the magnetic ring 4. The magnetic ring air pump 52 inflates the external airbag 5, which then clamps the rotary evaporator flask. Simultaneously, the external magnetic strip 51... The external air bladder 5, attached to the outer wall of the rotary evaporator, is inflated to ensure compatibility with rotary evaporators of different curvatures. A straight air pump 103 inflates the internal air bladder 10, causing the cleaning strip 101 to adhere to the inner wall of the rotary evaporator. The internal magnetic strip 102 is also positioned close to the inner wall of the rotary evaporator, allowing it to correspond to and attract the external magnetic strip 51. This inflation method ensures compatibility with rotary evaporators of different curvatures. Once the internal magnetic strip 102 and external magnetic strip 51 are attracted to each other and the cleaning strip 101 is attached to the inner wall of the rotary evaporator, a drive mechanism rotates the rotary evaporator.The rotating rotary evaporator flask allows the arc-shaped cleaning plate 9 to rotate relative to it, thus enabling the cleaning strip 101 to rotate relative to the flask for cleaning the interior. This method, during evaporation, cleans the interior of the rotary evaporator flask, reducing the amount of viscous paste adhering to its inner wall. When medication needs to be removed, the liquid inside the flask and the liquid on the arc-shaped plate 9 are removed separately, making it easier and more thorough to remove the medication from the flask. During cleaning, the cleaning strip 101 effectively cleans the interior of the rotary evaporator flask. Specifically, the straight strip 6 and arc-shaped plate 9 are designed to facilitate insertion into the interior of the rotary evaporator flask, and the internal gas... The internal air bladder 10 is inflated, allowing the cleaning strip 101 to contact and adhere to the inner wall of the rotary evaporator flask, ensuring effective cleaning. Simultaneously, the inflated internal air bladder allows the internal magnetic strip 102 to approach the inner wall of the rotary evaporator flask, improving its interaction with the external magnetic strip 51. A removable battery 104 provides power to the straight-line air pump 103 and the internal wireless repeater 105, facilitating the inflation and deflation of the internal air bladder 10. An operation panel 17 allows for convenient control of the magnetic ring air pump 52. Combined with the external wireless repeater 18 and the internal wireless repeater 105, the operation panel 17 facilitates the control of the straight-line air pump 103.

[0032] Combined with appendix Figure 1-7As shown, the driving mechanism includes a drive motor 14, which is disposed in the magnetic ring 4. The output end of the drive motor 14 is connected to a drive shaft 15, which is connected to a drive roller 16. The limiting mechanism includes a bottle cap 12 detachably mounted on the mouth of the rotary evaporator flask, a sliding limiting post 7 disposed at the end of the straight bar 6 away from the arc plate 9, a limiting frame 8 disposed on the ends of the two straight bars 6 near the sliding limiting post 7, and a limiting bolt 11 threadedly connected to the limiting frame 8 of the two straight bars 6 for limiting the position of the two straight bars 6. The bottle cap 12 has an annular sliding groove 13, and the sliding limiting post 7 can be slidably connected in the sliding groove 13. The drive motor 14 drives the drive roller 16 to rotate through the drive shaft 15. As the drive roller 16 rotates, when the rotary evaporator flask is placed in the magnetic ring 4, the drive roller 16 abuts against the rotary evaporator flask. The rotation of the moving roller 16 drives the rotary evaporator to rotate. A bottle cap 12 is installed at the mouth of the rotary evaporator. A sliding groove 13 is used to limit the sliding limit post 7. A limit bolt 11 can limit the position of the two straight bars 6 to ensure that the sliding limit post 7 can slide in the sliding groove 13. Since the bottle cap 12 limits the straight bars 6, it also limits the arc plate 9, so that the movement of the arc plate 9 is more stable. Preferably, the rotary evaporator can be driven by an external force, such as manually rotating the rotary evaporator, or a drive mechanism can be used to drive the rotary evaporator. For rotary evaporators of different sizes, an expansion ring can be added to the outside of the rotary evaporator to ensure that the drive roller 16 in the drive mechanism can smoothly drive the rotary evaporator to rotate.

[0033] Working principle: Taking cleaning as an example, insert the straight bar 6 and the arc plate 9 into the rotary evaporator flask. Adjust the position of the sliding limit post 7 so that it is located in the sliding groove 13. Then adjust the limit bolt 11 to determine the position of the arc plate 9. Through the operation panel 17, with the help of the external wireless repeater 18 and the internal wireless repeater 105, start the straight bar air pump 103 to inflate the internal air bag 10. Then place the rotary evaporator flask in the magnetic ring 4 and support it with the evaporation seat 1. Adjust the position of the rotary evaporator flask. With the help of the operation panel 17, the magnetic ring air pump 52 inflates the external air bag 5. After inflation, the external magnetic strip 51 contacts the outer wall of the rotary evaporator flask. The inflated internal air bag 10 facilitates cleaning. The cleaning strip 101 contacts the inner wall of the rotary evaporator, and the inner magnetic strip 102 is close to the inner wall of the rotary evaporator. The position of the rotary evaporator is readjusted so that the outer magnetic strip 51 corresponds to the inner magnetic strip 102. Then, the drive motor 14 is started, which drives the drive roller 16 to rotate through the drive shaft 15. The rotating drive roller 16 drives the rotary evaporator to rotate. The rotating rotary evaporator causes the cleaning strip 101 to move relative to the rotary evaporator. The moving cleaning strip 101 can clean the inside of the rotary evaporator. If the rotary evaporator is driven to rotate by an external force, the drive motor 14 needs to be stopped and the rotary evaporator is driven to rotate by an external force instead of the drive motor 14.
