Description

Technical Field

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

[0002] Rotary evaporators use a motor to drive the evaporation flask to rotate continuously, causing the liquid to form a large-area thin film on the flask wall, significantly increasing the area for heating and evaporation. Combined with a vacuum system to lower the solvent boiling point, this allows for rapid evaporation at low temperatures while protecting heat-sensitive substances and completely preventing bumping. However, while existing rotary evaporators can achieve the effect of liquid rotational evaporation, they still have the following drawbacks: First, there is no protective device on top of the distillation flask, which may cause hot water to splash and contaminate the instrument or burn staff when the flask is rotating.

[0003] Secondly, in the existing technology, the condenser tube and the collection bottle are only fixed by clamps. The existing clamps rely on mechanical clamping force to act directly on the interface between the end of the condenser tube and the mouth of the collection bottle, lacking auxiliary positioning or buffer structure. There may be a risk of the interface loosening during use. Utility Model Content

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Example 1: like Figure 1-6 As shown, a rotary evaporator includes a condenser 3, a collection bottle 5, a rotating fixing device 24, an adjusting support frame 1, a distillation flask 2, and a hot water bath 4. The distillation flask 2 consists of a body and a neck. The feature is that it also includes a protective cover 12. The protective cover 12 is detachably connected to the top of the hot water bath 4 via a fixing mechanism; the protective cover 12 is fitted onto the bottle body to form a closed structure; the protective cover 12 has a vertical notch 17, through which the bottle neck can pass. The fixing mechanism includes a snap-fit ​​block 13 on the protective cover 12, a fixing block 14 on the hot water bath 4, and the snap-fit ​​block 13 can be inserted into the fixing block 14; the snap-fit ​​block 13 has a snap-fit ​​groove 15, and the fixing block 14 has a snap-fit ​​hook 16 hinged to it, and the snap-fit ​​hook 16 and the snap-fit ​​groove 15 can be fitted and snapped together.

[0030] Application results: By detachably connecting the protective cover 12 to the hot water bath 4, the problems of hot water splashing and contaminating instruments and scalding staff during experiments are solved, thus improving the safety of the experiment.

[0031] In some embodiments, the top of the protective cover 12 is hemispherical, making the protective cover 12 without blind spots, aesthetically pleasing and easy to clean.

[0032] In some embodiments, the condenser tube 3 is provided with an air inlet 31 and a water outlet 32, and the water outlet 32 ​​is connected to the collection bottle 5; a reinforcing mechanism is also provided between the condenser tube 3 and the collection bottle 5, the reinforcing mechanism includes a threaded tube 6, the top end of the threaded tube 6 is detachably connected to the air inlet 31 of the condenser tube 3, a threaded rod 7 is internally threaded on the threaded tube 6, a lifting plate 8 is sleeved on the threaded rod 7, and the lifting plate 8 supports the bottom end of the collection bottle 5.

[0033] Application results: The system uses a threaded tube 6, a threaded rod 7, and a lifting plate 8. One end of the threaded tube 6 is detachably connected to the condenser tube 3. The threaded rod 7 is connected to the threaded tube 6 internally. The lifting plate 8 is fitted on the threaded rod 7. Simply turning the threaded rod 7 will cause the lifting plate 8 to rise, thereby pressing against the bottom of the collection bottle 5, making the interface between the collection bottle 5 and the condenser tube 3 more secure. This simple operation also prevents the interface between the condenser tube 3 and the collection bottle 5 from loosening.

[0034] In some embodiments, the top end of the threaded tube 6 is connected to a hook 9, which is hung on the outer wall of the air inlet 31. It only needs to be hung on the condenser tube 3, and the threaded rod 7 can generate a counter-pulling force to make the connection between the collection bottle 5 and the condenser tube 3 tighter.

[0035] In some embodiments, the top end of the threaded pipe 6 is connected to two clamps 10, which are bolted together and fixed to each other. The two clamps 10 are fitted onto the outer wall of the air inlet 31 of the condenser pipe 3. The connection of the clamps 10 is more stable, which further enhances the stability of the overall device.

[0036] In some embodiments, the lifting plate 8 is provided with a circular notch 11, and the bottom end of the collection bottle 5 is locked in the circular notch 11; the bottom end of the collection bottle 5 is locked in the circular notch 11; the force on the collection bottle 5 is more even, and the force deviation is reduced; the connection between the collection bottle 5 and the condenser pipe 3 is more stable.

[0037] In some embodiments, a flexible protective sleeve is covered on the circular notch 11 to prevent the collection bottle 5 from being scratched by the reinforcement device, while also increasing the friction to further prevent the interface between the collection bottle 5 and the condenser tube 3 from loosening.

[0038] In some embodiments, the lifting plate 8 includes a first clamping plate 20 and a second clamping plate 21. The first clamping plate 20 can be inserted into the second clamping plate 21, and a tension spring 19 is provided between the first clamping plate 20 and the second clamping plate 21. The first clamping plate 20 is provided with two insert rods 18, and the second clamping plate 21 is provided with two through holes. The insert rods 18 can be adapted to be inserted into the through holes, and the tension spring 19 is sleeved on the insert rods 18. Only by pulling the first clamping plate 20 and the second clamping plate 21 can the collection bottle 5 be locked between the first clamping plate 20 and the second clamping plate 21, making the overall structure more stable.

[0039] In some embodiments, the tension springs are symmetrically arranged between the first clamping plate and the second clamping plate, which can ensure the stability of the clamping force and prevent it from shifting, making the connection between the reinforcement mechanism and the collection bottle 5 more secure.

[0040] Example 2: like Figure 7As shown, considering that the protective cover 12 in Embodiment 1 is directly connected to the hot water bath 4 through a fixing mechanism, this structure still has the problem of not being able to adapt to different hot water baths 4. In order to make the device more perfect, this embodiment proposes a rotary evaporator. The other structures are the same as in Embodiment 1, except that it also includes a disassembly ring 22. The disassembly ring 22 is provided with at least one set screw 23. The set screw 23 supports the outer wall of the hot water bath 4. The protective cover 12 and the disassembly ring 22 are connected through a fixing mechanism.

[0041] Work process: First, transfer the solution to be distilled into the distillation flask 2, and then connect and fix the distillation flask 2 to the rotary evaporator head; next, operate the reinforcement mechanism to pull open the first clamp 20 and the second clamp 21, clamp the collection bottle 5 to stabilize its position, and fix the clamp 10 of the reinforcement mechanism to the air inlet 31 on the condenser tube 3 with bolts.

[0042] Adjust the height of the collection bottle 5 by screwing the threaded rod 7 to ensure precise alignment with the outlet 32 ​​of the condenser tube 3. Then, further reinforce the interface with a butterfly clamp to ensure a tight connection. Add an appropriate amount of hot water to the hot water bath 4 and adjust the height of the distillation flask 2 to the appropriate depth for immersion in the hot water bath.

[0043] Finally, place the disassembly ring 22 onto the hot water bath 4, screw the set screw 23 on the disassembly ring 22 to fix the disassembly ring 22 onto the hot water bath 4, insert the snap block 13 on the protective cover 12 into the fixing block 14 of the fixing mechanism, press the snap hook 16 to make it snap into the slot 15 to complete the fixing, start the rotary evaporator until the experiment ends.

[0044] In summary, this rotary evaporator has a stable structure and is easy to operate. It can be quickly installed or disassembled without complicated tools, which solves the problem of unstable connection between the existing condenser tube 3 and the collection bottle 5. It is also equipped with a protective cover 12 to prevent hot water from splashing out and scalding the experimenters, further enhancing its stability.
