Description

Technical Field

[0001] This utility model relates to the field of rotary evaporator cleaning technology, specifically a rotary evaporator that is easy to clean. Background Technology

[0002] A rotary evaporator, also known as a rotary distillation apparatus, is a widely used evaporation instrument in laboratories. It consists of a motor, distillation flask, heating pan, condenser, and other components. It is mainly used for the continuous distillation of volatile solvents under reduced pressure and is applied in fields such as chemistry, chemical engineering, and biomedicine.

[0003] After evaporation, existing rotary evaporators leave solid or semi-solid residues, such as extracts, inside the evaporation flask. Current methods mostly involve adding solvents to reduce the adhesion of the extract to the flask, allowing it to be poured out. However, this method results in the extract containing solvent, requiring further solvent treatment if the extract is to be used. While this method can effectively collect the solvent, subsequent operations are cumbersome and not conducive to cleaning the extract.

[0004] Therefore, it is necessary to propose a rotary evaporator that is easy to clean. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a convenient rotary evaporator that can clean the extract inside the evaporation flask using ultrasonic assistance and hand scraping, reducing the introduction of other solvents and maintaining the original quality and active ingredients of the extract, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a rotary evaporator that is easy to clean, comprising a support platform, an evaporation flask, and an ultrasonic cleaning tank:

[0007] The support platform is equipped with an ultrasonic cleaning machine tank inside, and sliding grooves are provided on both sides of the support platform;

[0008] A slider is slidably connected inside the first slide groove. A support block is fixedly connected to the upper surface of the slider. A second slide groove is opened inside the support block. A movable bearing block is slidably connected inside the second slide groove. A connecting rod is rotatably connected inside the movable bearing block. A top plate is fixedly connected to the side of the movable bearing block. A bottom plate is fixedly connected to one side of the lower surface of the support block. An electric telescopic rod is installed on the upper surface of the bottom plate. The output end of the electric telescopic rod is installed on the lower surface of the top plate.

[0009] Preferably, a semi-circular block is fixedly connected to the other end of the connecting rod, a friction plate is fixedly connected to the inner side of the semi-circular block, and several sets of elastic clamps are fixedly connected at equal intervals on the lower surface of the semi-circular block.

[0010] Preferably, the inner side of the friction plate is in contact with the outer surface of the port of the evaporation flask, and the inner side of the elastic clamp is in contact with the outer surface of the evaporation flask body.

[0011] Preferably, the slide groove is rotatably connected to a threaded rod, and the outer surface of the threaded rod is threadedly connected to the inner surface of the slide block.

[0012] Preferably, a motor is installed on the outer side of the slide groove, and the output shaft of the motor is fixedly connected to the end of the threaded rod.

[0013] Preferably, a second motor is installed on the side of the top plate, and the output shaft of the second motor is fixedly connected to the end of the connecting support rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This convenient rotary evaporator, when cleaning the extract inside the evaporation flask, involves adding an appropriate amount of distilled and deionized water to the ultrasonic cleaning tank. The evaporation flask to be cleaned is placed in the upper center of the ultrasonic cleaning tank. By controlling the movement of the connecting rod, a semi-circular block at the end of the connecting rod clamps the mouth of the evaporation flask. Simultaneously, an elastic clamp at the bottom of the connecting rod wraps around the flask surface. By controlling the height of the evaporation flask, it is immersed in the liquid inside the ultrasonic cleaning tank, with the water level exceeding the liquid level of the material inside the evaporation flask. The ultrasonic cleaning tank operates, and the ultrasonic waves generate tiny bubbles near the evaporation flask wall, creating a cavitation effect that gradually loosens and detaches the material from the edges. At this point, by controlling... The tilted opening of the evaporation flask facilitates the use of a hand-held scraper, starting from the neck of the evaporation flask and slowly moving along the flask wall towards the bottom. The curved blade of the scraper conforms to the curvature; by gently pressing and rotating the scraper, ultrasonic vibration assists the blade in cutting into the interface between the material and the flask wall. The scraped material is guided along the blade to the flask opening for collection, preventing it from sticking back to the flask wall. This gradually collects the extract inside the evaporation flask. This structure, through ultrasonic-assisted collection of the extract inside the evaporation flask, utilizes the high-frequency vibration generated by ultrasound to effectively reduce the adhesion between the extract and the evaporation flask wall, causing the extract to quickly detach from the flask wall. This not only significantly improves scraping efficiency, saving labor and time costs, but also reduces extract residue, significantly improving recovery efficiency. At the same time, it stabilizes the quality and active ingredients of the extract, avoids the introduction of solvents, and reduces the risk of extract contamination. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A rotary evaporator that is easy to clean includes a support platform 1, an evaporation flask 2, and an ultrasonic cleaning tank 110.

[0027] An ultrasonic cleaning machine tank 110 is installed inside the support platform 1, and sliding grooves 4 are opened on both sides of the support platform 1.

[0028] A slider 421 is slidably connected inside the slide groove 4. A support block 430 is fixedly connected to the upper surface of the slider 421. A slide groove 490 is opened inside the support block 430. A movable bearing block 440 is slidably connected inside the slide groove 490. A connecting support rod 3 is rotatably connected inside the movable bearing block 440. A top plate 460 is fixedly connected to the side of the movable bearing block 440. A bottom plate 470 is fixedly connected to one side of the lower surface of the support block 430. An electric telescopic rod 480 is installed on the upper surface of the bottom plate 470. The output end of the electric telescopic rod 480 is installed on the lower surface of the top plate 460.

[0029] The operation of the electric telescopic rod 480 can push the top plate 460 to move up and down. Since the top plate 460 is connected to the movable support block 440, the movable support block 440 can move synchronously. The connecting rod 3 is connected to the movable support block 440, so that the connecting rod 3 also moves with the movable support block 440, further driving the evaporation bottle 2 into the water level inside the ultrasonic cleaning tank 110.

[0030] The ultrasonic cleaning tank 110 model is available from the LY series. When the ultrasonic cleaning tank 110 operates ultrasonically, the ultrasonic waves generate tiny bubbles near the walls of the evaporation flasks, creating a cavitation effect that gradually loosens and separates the material from its edges.

[0031] As a preferred technical solution of this utility model, a semi-circular block 310 is fixedly connected to the other end of the connecting support rod 3. A friction plate 320 is fixedly connected to the inner side of the semi-circular block 310. Several sets of elastic clamps 330 are fixedly connected at equal intervals on the lower surface of the semi-circular block 310. The inner side of the friction plate 320 is in contact with the outer surface of the port of the evaporating bottle 2. The inner side of the elastic clamps 330 is in contact with the outer surface of the bottle body of the evaporating bottle 2. A threaded rod 420 is rotatably connected inside the slide groove 4. The outer surface of the threaded rod 420 is threadedly connected to the inner surface of the slider 421.

[0032] By controlling the operation of the threaded rod 420, the slider 421 is driven to move. The support block 430 for supporting the connecting rod 3 is installed on the upper surface of the slider 421, so that the connecting rod 3 moves towards the middle position of the ultrasonic cleaning tank 110. At this time, the evaporation bottle 2 to be cleaned is placed in the upper middle position of the ultrasonic cleaning tank 110. By controlling the movement of the connecting rod 3, the semi-circular block 310 at the end of the connecting rod 3 is clamped at the mouth of the evaporation bottle 2. At the same time, the elastic clamp 330 at the bottom of the connecting rod 3 wraps around the bottle surface of the connecting rod 3. The friction plate 320 connected to the semi-circular block 310 increases the friction with the mouth of the evaporation bottle 2, improving the stability of the semi-circular block 310 clamping the evaporation bottle 2.

[0033] As a preferred technical solution of this utility model, a motor 410 is installed on the outer side of the slide groove 4, and the output shaft of the motor 410 is fixedly connected to the end of the threaded rod 420.

[0034] The operation of motor 410 can drive the threaded rod 420 to rotate, thereby controlling the clamping of the evaporation flask 2.

[0035] As a preferred technical solution of this utility model, a second motor 450 is installed on the side of the top plate 460, and the output shaft of the second motor 450 is fixedly connected to the end of the connecting support rod 3.

[0036] The operation of motor 450 drives the connecting rod 3 to rotate, causing the mouth of evaporating flask 2 to tilt. This makes it easier to hold the scraper and move it slowly from the neck of evaporating flask 2 along the flask wall to the bottom. The curved scraper fits the curvature, and by gently pressing and rotating the scraper, ultrasonic vibration is used to assist the blade in cutting into the interface between the material and the flask wall. The scraped material can be guided along the blade to the mouth of the flask for collection, avoiding sticking back to the flask wall, and gradually collecting the extract inside evaporating flask 2.
