Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a rotary evaporator. Background Art

[0002] A rotary evaporator is a commonly used instrument for solvent evaporation and concentration in laboratories. It rotates the evaporation flask to form a thin film of the solution on the flask wall, thereby increasing the evaporation area of the solvent and improving the evaporation efficiency. However, in actual use, some problems are often encountered. One of them is that the solution may splash during the evaporation process, and part of the solution will splash out from the inside of the instrument and adhere to the outer surface of the instrument. This situation not only causes loss of the solution but also makes the cleaning of the instrument extremely difficult. Because the splashed solution may adhere to every corner of the instrument, even some inaccessible places, more time and effort are required for cleaning, and sometimes special cleaning agents or tools are needed to completely remove it.

[0003] In the patent "Rotary Evaporator Easy to Clean" (publication number CN213316663U, hereinafter referred to as the prior art 1), a rotary evaporator easy to clean is disclosed.

[0004] Although the prior art 1 successfully realizes the convenient cleaning of the rotary flask of the rotary evaporator by combining the airbag and the cleaning brush, in actual use, due to the problem of liquid splashing still existing, the outside of the evaporation flask will also become dirty. However, the design and setting in the prior art 1 make it difficult to clean this part of the external dirt. In addition, the cleaning method in the prior art 1 is mainly applicable to the removal of liquid-like residual pollutants, but for those solid or viscous pollutants attached to the side wall of the rotary flask, this method is inadequate and difficult to completely remove. Summary of the Utility Model

[0005] In view of this, the embodiment of the utility model provides a rotary evaporator to solve the problem that all residual pollutants in the rotary flask cannot be completely removed in the prior art.

[0032] Embodiment 1

[0033] Please refer to Figure 1, an embodiment of the present utility model provides a rotary evaporator, which is widely used in laboratories for concentrating and drying samples. The working principle of the rotary evaporator mainly relies on the evaporation and condensation processes to efficiently separate solvents in liquid mixtures. The core component of the rotary evaporator is the evaporation flask of the rotary evaporator. The rotary flask 110 is rotated during operation. The role of rotation is to increase the evaporation area of the liquid and at the same time reduce the evaporation temperature of the liquid, thereby improving the evaporation efficiency. Rotation also helps the liquid to be evenly distributed on the inner surface of the flask. The rotary flask 110 is usually placed in a thermostatic heating bath, and heat is provided through heating to cause the liquid solvent to evaporate. The temperature of the heating bath can usually be adjusted to meet the evaporation requirements of different solvents. The rotary evaporator is also equipped with a vacuum system, which reduces the pressure inside the system and lowers the boiling point of the solvent. This means that even at a lower temperature, the liquid can evaporate, reducing the risk of thermal degradation of heat-sensitive substances. The evaporated solvent vapor enters the cooling system through the condenser tube. The cooling system usually uses ice water or other cooling media to lower the temperature of the vapor and condense it into a liquid. The condensed liquid is collected in a receiving flask, so that the solvent and solute can be separated. The receiving flask is usually connected to the condensation system to ensure that the collected liquid is separated from the evaporation process.

[0034] Traditional rotary evaporators have some inconveniences in the cleaning of various parts, especially for the cleaning of the rotary flask 110. Since the rotary flask 110 usually selects a specific size, this may make the rotary flask 110 difficult to disassemble and clean during use. To ensure that the rotary flask 110 can be thoroughly cleaned, a special cleaning mechanism is provided. This cleaning mechanism is not only for thoroughly cleaning the rotary flask 110, but also has flexible adaptability. By replacing different types of cleaning nozzles, this cleaning mechanism can also be used to clean and dry other components of the rotary evaporator. In this way, whether it is the rotary flask 110 or other key components, they can be efficiently cleaned and maintained through this cleaning mechanism, greatly improving the overall use efficiency and cleanliness of the rotary evaporator.

[0035] Please refer to Figure 2, in this embodiment, the rotary evaporator mainly consists of an evaporation assembly 100 and a water bath 200. The evaporation assembly 100 is responsible for providing the environment and conditions required for evaporation, while the water bath 200 is used to provide a stable heat source to ensure the smooth progress of the evaporation process. Through the close cooperation and coordinated work of these two components, the rotary evaporator can achieve its basic composition and complete its basic functions. Specifically, the evaporation assembly 100 usually includes a rotating evaporation flask. During rotation, the evaporation flask can evenly distribute the solution on the inner wall of the flask, thereby increasing the contact area between the solution and the evaporation surface and improving the evaporation efficiency. At the same time, the evaporation assembly 100 also includes a vacuum system for reducing the pressure inside the evaporation flask to further promote the evaporation of the solvent. The water bath 200 provides a constant-temperature environment for the evaporation process by precisely controlling the temperature, preventing the solvent from decomposing or deteriorating due to excessive temperature during evaporation. In addition, the water bath 200 can also achieve uniform temperature distribution through a circulation system to ensure the stability and reliability of the entire evaporation process.

[0036] Please refer to Figure 2 , to further improve the use effect of the water bath 200, a matching pot cover 230 is equipped for the water bath 200. This pot cover 230 not only covers the top of the water bath 200, but also has a structure with a partially open opening 231 on its surface. Such a setting enables the pot cover 230 to maintain good connectivity with the interior of the water bath 200. With this structure, the pot cover 230 can effectively cover the water bath 200, thereby preventing the evaporated solution from splashing everywhere during heating and ensuring the cleanliness and safety of the experimental environment. At the same time, since the opening 231 is provided on the pot cover 230, the evaporated solution can intelligently fall back into the interior of the water bath 200, avoiding waste of the solution and environmental pollution. In addition, the setting of the opening 231 also allows the evaporation assembly 100 to pass through smoothly, so that the evaporation assembly 100 will not be hindered when used in conjunction with the water bath 200, thus ensuring the smooth progress of the experimental operation. During use, first place the rotary flask 110 inside the water bath 200, and then cover the water bath 200 and the rotary flask 110 with the pot cover 230.

[0037] Please refer to Figure 3, in this embodiment, the water bath 200 includes two main parts: an inner tank 210 and an outer shell 220. Specifically, the inner tank 210 is placed in the inner space of the outer shell 220. To further enhance the structural stability and practicality, a special installation groove 221 is provided at the top of the outer shell 220. This installation groove 221 not only plays a fixing role but also provides convenience for subsequent operations. At the same time, to match the installation groove 221 of the outer shell 220, a protruding structure 232 adapted to it is provided at the bottom of the pot cover 230. This setting enables the pot cover 230 to be firmly installed on the outer shell 220 while maintaining a certain degree of flexibility. With this structure, the operator can easily place the pot cover 230 on the inner tank 210 and adjust the orientation of the opening 231 by rotating the pot cover 230. This improves the usability of the water bath 200 and also ensures that during use, the pot cover 230 can be flexibly adjusted according to actual needs to meet different experimental requirements. Further, a handle is provided at the top of the pot cover 230, and the orientation angle of the opening 231 can be adjusted by turning its handle. Moreover, the pot cover 230 of the water bath 200 is provided with a heat insulation layer, so that the temperature of the pot cover 230 does not rise with the operation of the water bath 200, and the handle does not heat up either, making the adjustment of the orientation of the opening 231 of the pot cover 230 safer.

[0038] Please refer to Figure 4 , on one side of the water bath 200, a cleaning mechanism is set and installed to ensure that all components of the evaporation assembly 100 can be thoroughly cleaned. The cleaning mechanism mainly includes a cleaning cylinder 410 and a spray head. The spray head is set to be detachable for easy installation and maintenance, and it is fixed on the cylinder rod 411 of the cleaning cylinder 410. The spray head is connected to a pressure tank 440 to ensure sufficient pressure during the cleaning process.

[0039] The main function of the cleaning mechanism is to effectively clean all components of the evaporation assembly 100. To achieve this function, the cleaning component pumps water through a pressure pump. The pressure pump is connected to a water supply unit to ensure continuous supply of water source. The water supply unit is responsible for providing the water source, and the pressure pump transports the water source through a pipeline to the spray head. The spray head is responsible for spraying water onto all parts of the evaporation assembly 100 during the cleaning process, thus achieving the purpose of pumping water and cleaning.

[0040] Please refer to Figure 4, the setting of the spray head is very flexible. It is set on the cylinder rod 411 and can be extended or shortened through the telescopic movement of the cylinder rod 411. This setting enables the spray head to adjust the displacement position, so that it can flexibly clean different parts of the evaporation assembly 100. No matter how complex the structure of the evaporation assembly 100 is, the spray head can be adjusted to the optimal cleaning position through the telescopic movement of the cylinder rod 411 to ensure that every corner can be thoroughly cleaned. This flexible cleaning method not only improves the cleaning efficiency but also ensures the uniformity and thoroughness of the cleaning effect.

[0041] Effective connectivity is achieved between the pressure tank 440 and the water supply unit; on the rotary bottle 110 of the evaporation assembly 100, a cleanable opening 111 is specially provided. Further, in this embodiment, a rotary bottle 110 with a cleanable opening 111 is also provided. The setting of this cleanable opening 111 enables the rotary bottle 110 originally with only one inlet to have two openings with different functions. These two openings have different functions respectively: one is used to add substances required for the reaction, and the other is used for the entry and cleaning operation of the cleaning mechanism. It improves the utilization efficiency of the rotary bottle 110 and facilitates the maintenance and cleaning work of the equipment, thus ensuring the stable operation of the entire evaporation system and extending the service life of the equipment. The spray head enters or exits the pressure tank 440 through the cleanable opening 111 by the cleaning cylinder 410 for cleaning operations. When in use, when pressurizing, the pressure tank 440 pressurizes the cleaning agent so that it is sprayed inside the rotary bottle 110. When performing negative pressure adsorption, the connection with each water pipe is closed to make the pressure tank 440 generate negative pressure to adsorb water stains.

[0042] Furthermore, at the position of the cleanable opening 111 of the rotary bottle 110, a sealing cover 112 is specially set and installed. The function of this sealing cover 112 is to ensure that the cleanable opening 111 can be in an open or closed state, specifically depending on the installation of the sealing cover 112. When it is necessary to clean or maintain the rotary bottle 110, the sealing cover 112 can be easily removed from the cleanable opening 111 to achieve the purpose of opening the cleanable opening 111. When the sealing cover 112 is installed, once the sealing cover 112 is correctly engaged with the cleanable opening 111, a sealing setting is formed to ensure the complete isolation between the inside and the outside environment of the rotary bottle 110.

[0043] This setting is particularly important when the rotary flask 110 performs the evaporation operation. To ensure the smooth progress of the evaporation process, it is necessary to ensure that the environment inside the rotary flask 110 is closed and stable. Therefore, before the evaporation operation starts, the sealing cap 112 must be correctly installed at the cleaning port 111 to ensure that the cleaning port 111 is completely closed and in a sealed state. Only in this way can the evaporation environment inside the rotary flask 110 reach the required closed and stable conditions, enabling the evaporation assembly 100 to operate smoothly. In this way, the chemical substances or solvents during the evaporation process will not leak into the external environment, ensuring the safety of the experiment and the accuracy of the results.

[0044] Furthermore, the water supply unit includes a first water supply unit 510, a second water supply unit 520, and a third water supply unit 530. These three water supply units are independent of each other and store different types of water to meet different water usage requirements. To ensure that the water in each water supply unit does not mix, the pressure tank 440 is connected to these water supply units through a series of water pipes 441. Specifically, the pressure tank 440 is connected to the first water supply unit 510, the second water supply unit 520, or the third water supply unit 530 through a group of independent water pipes 441. In this way, when water is needed, one of the water supply units can be selected for connection according to the actual demand. This setting not only avoids the mixing of different water sources but also improves the flexibility and reliability of the water supply unit. Through independent water supply units and dedicated water pipes 441, different types of water can be effectively controlled and managed to ensure a stable and high-quality water source under various circumstances. Water valves are respectively installed in the water pipes between each water supply unit, so that different liquids will not enter other parts of the water supply unit, ensuring the independence of each water supply unit. In addition, this setting also facilitates maintenance and repair because the connections between each water supply unit and the pressure tank 440 are independent and do not interfere with each other.

[0045] Furthermore, the first water supply unit 510 is specifically set as a cleaning liquid storage unit, whose main function is to store the cleaning liquid used to clean each component of the evaporation assembly 100. Through this cleaning liquid, each component of the evaporation assembly 100 can be effectively and thoroughly cleaned to ensure its cleanliness. The second water supply unit 520 is set as a clean water storage unit, whose main role is to perform secondary cleaning after the initial cleaning of each component of the evaporation assembly 100. By using clean water, the stains remaining during the initial cleaning process can be thoroughly flushed away to ensure that there are no remaining stains on each part of the evaporation assembly 100 after the cleaning is completed. After the cleaning work is completed, a negative pressure is generated by the pressure tank 440 to suck away the cleaned liquid and transport it to the third water supply unit 530. The function of the third water supply unit 530 is to serve as a sewage collection unit for collecting and storing the sewage generated during the cleaning process. In addition, during the process of secondary cleaning, multiple cleaning operations are required to ensure that the cleanliness of the evaporation assembly 100 reaches the highest standard. Through this method of multiple cleanings, it can be ensured that the performance and efficiency of the evaporation assembly 100 will not be affected by the remaining stains during use.

[0046] Please refer to Figure 4 , furthermore, the spray head is set as the first cleaning spray head 421; the first cleaning spray head 421 is installed on the cylinder rod 411; the first cleaning spray head 421 is spherical in shape, and a number of densely arranged water holes are distributed on the surface of the first cleaning spray head 421; the spraying or suction angle of each water hole is different. The first cleaning spray head 421 is spherical in shape, so that the sprayed cleaning liquid can achieve the effect of a larger cleaning area and cover the position inside the rotary bottle 110. By providing a large number of water holes, a large number of independent water columns are sprayed, resulting in a better cleaning effect.

[0047] On the first cleaning spray head 421, a cleaning sleeve (not shown) is also specially provided and installed. This cleaning sleeve is placed on the surface of the first cleaning spray head 421 to ensure a tight fit. The cleaning sleeve itself has a certain thickness, and this setting is intended to provide an additional protective layer to prevent any potential damage to the rotary bottle 110 during the cleaning process. In addition, a number of through holes are provided on the surface of the cleaning sleeve, and these through holes can effectively guide the cleaning liquid through to ensure the uniformity and thoroughness of the cleaning effect.

[0048] Please refer to Figure 4, after completing the cleaning work inside the rotary bottle 110, it is necessary to use the first cleaning nozzle 421 to suck out the solution inside the bottle. Since direct contact may occur between the first cleaning nozzle 421 and the rotary bottle 110, this contact may damage the rotary bottle 110. To avoid this situation, a cleaning sleeve is provided and installed on the first cleaning nozzle 421. In this way, during the cleaning process, the cleaning sleeve can contact the rotary bottle 110, thus greatly reducing the potential damage risk to the rotary bottle 110 and making it safer and more reliable when contacting the rotary bottle 110.

[0049] To achieve this process, we utilize the negative pressure generated by the pressure tank 440. Through this negative pressure effect, the liquid inside the rotary bottle 110 can be effectively sucked out, thereby achieving the effect of drying the rotary bottle 110. In this way, the liquid inside the rotary bottle 110 is completely removed, ensuring the efficiency and thoroughness of the cleaning process.

[0050] In addition, please refer to Figure 4 , the first cleaning nozzle 421 extends or contracts through a water pipe 441 connected to the pressure tank 440. This setting enables the cleaning nozzle to flexibly adjust its position to adapt to rotary bottles 110 of different sizes and shapes, thereby further improving the flexibility and efficiency of cleaning.

[0051] In terms of the overall structure setting, the evaporation assembly 100 and the water bath 200 are set as a separated structure. This setting not only facilitates the individual use and maintenance of each component but also enables convenient separate cleaning treatment of each part. To further enhance the stability and safety of the equipment, anti-slip foot pads 300 are evenly distributed at the bottoms of the evaporation assembly 100 and the water bath 200. These anti-slip foot pads 300 can not only prevent the equipment from sliding during use but also ensure that the equipment remains stable in various working environments, thus providing a safer and more reliable usage experience for the operator.

[0052] Embodiment 2

[0053] Please refer to Figure 5 , the embodiment of the present utility model provides a rotary evaporator. In this embodiment, we introduce the setting of a second cleaning nozzle 430. Different from the first cleaning nozzle 421 in the previous Embodiment 1, the first cleaning nozzle 421 is mainly used for cleaning the rotary bottle 110 in the evaporation assembly 100. However, when the first cleaning nozzle 421 is used to clean other components of the evaporation assembly 100, the effect is often not satisfactory, and it even cannot reach the positions of some components, resulting in an incomplete cleaning task. Therefore, to make up for this deficiency, the second cleaning nozzle 430 is set.

[0054] The second cleaning nozzle 430 is different from the first cleaning nozzle 421 in terms of structure and installation position. Specifically, the second cleaning nozzle 430 is not installed on the cleaning cylinder 410 like the first cleaning nozzle 421, but is directly connected to the pressure tank 440 through a water pipe 441. This setting enables the second cleaning nozzle 430 to operate independently of the cleaning cylinder 410.

[0055] The outer shape of the second cleaning nozzle 430 is set to be cylindrical for easy installation and use. During use, the second cleaning nozzle 430 can be detached from the cleaning cylinder 410 and perform the cleaning operation independently. Through the negative pressure or positive pressure generated by the pressure tank 440, the second cleaning nozzle 430 can achieve the functions of water absorption or water spraying, thereby performing effective cleaning.

[0056] During the cleaning operation, first place the evaporation component 100 in a cleaning pool that is convenient for cleaning. The operator holds the second cleaning nozzle 430 and adjusts the appropriate pressure according to needs to avoid damaging the evaporation component 100, and uses the cleaning liquid to thoroughly flush the evaporation component 100. After the cleaning is completed, use clean water to perform a secondary cleaning on the evaporation component 100 to ensure that all residual cleaning liquid is completely removed.

[0057] After the cleaning work is completed, through the negative pressure generated by the pressure tank 440, the residual water stains on the evaporation component 100 can be effectively absorbed, and the sewage is discharged into the third water supply unit 530. This not only achieves a thorough cleaning of the evaporation component 100, but also facilitates the recycling or environmental protection treatment of the sewage, ensuring the environmental friendliness of the entire cleaning process.

[0058] Through the setting of the second cleaning nozzle 430, we have solved the problem of the positions that the first cleaning nozzle 421 cannot reach, and achieved a comprehensive cleaning of all parts of the evaporation component 100. In addition, the independent operation mode of the second cleaning nozzle 430 makes the cleaning process more convenient and efficient, and at the same time improves the drying effect, ensuring the cleanliness and working efficiency of the evaporation component 100.

[0059] Furthermore, the second cleaning nozzle 430 extends or contracts through a water pipe 441 connected to the pressure tank 440. This setting enables the second cleaning nozzle 430 to move flexibly, so that it can reach different cleaning positions. Whether it is the stains at high places or the dead corners at low places, the second cleaning nozzle 430 can easily handle them to ensure that every corner can be thoroughly cleaned. This flexibility greatly improves the cleaning efficiency and also makes the operation more convenient. The user can adjust the position of the nozzle according to actual needs to achieve the best cleaning effect.

[0060] Further, in Embodiment 1, it is necessary to dry the rotating bottle 110 through the first cleaning nozzle 421. However, the first cleaning nozzle 421 may not be able to perform cleaning or drying in all directions. Therefore, the first cleaning nozzle 421 can be installed on the water pipe 441 and extended into the rotating bottle 110 for cleaning or drying operations.

[0061] Further, to ensure the drying effect inside the rotating bottle 110, the water bath 200 can also be started to heat the rotating bottle 110 to evaporate the clean water stains.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
