[0002] The plant extraction industry is an emerging sector at the intersection of pharmaceuticals, fine chemicals, and agriculture. Plant extraction uses plants as raw materials and, according to the intended use of the final product, employs physicochemical extraction and separation processes to selectively obtain and concentrate one or more active ingredients from the plant without altering their structure. Depending on the extracted plant components, products can be categorized as glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc.; and according to their physical properties, they can be classified as plant oils, extracts, powders, crystals, etc.

[0003] The reaction vessel of existing extraction devices is usually cleaned after use to facilitate the next use. However, for some oils, obvious deposits may appear on the inner wall of the reaction vessel during use. Cleaning afterward cannot guarantee the reaction efficiency during use, which is a shortcoming. Utility Model Content

The other side of the outer wall of the two cleaning scrapers is slidably attached to the inner wall of the reactor. A motor is fixedly connected to the outer wall of the mounting cover. A bevel gear is fixedly sleeved on the output end of the motor. The bevel gear meshes with a bevel gear ring.

[0008] As a further description of the above technical solution:

[0009] A steam inlet pipe is fixedly connected to the side of the reactor near the lower end face, and a cold water inlet pipe and a hot water outlet pipe are fixedly sleeved on one side of the condenser, with the cold water inlet pipe located below the hot water outlet pipe.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, this rapid organic solvent extraction device for plant extraction uses a structure consisting of an installation ring, a bevel gear, a bevel tooth ring, a cleaning scraper, and a stirring rod that works together. The motor drives the bevel gear to rotate, which in turn drives the bevel tooth ring to rotate, which in turn drives the installation ring to rotate. This, in turn, drives the stirring rod to rotate through two cleaning scrapers. The rotating cleaning scrapers clean the inner wall of the reaction vessel in real time, preventing excessive adhesion of impurities. At the same time, the rotating stirring rod can also play a stirring role during the process, avoiding local overheating or excessively low temperature.

[0018] 2. Compared with existing technologies, this rapid organic solvent extraction device for plant extraction, through the coordinated structure of mounting blocks, slots, locking blocks, pull rods and springs, can assist in the quick installation and removal of the mounting cover, which is convenient and time-saving.

[0026] Reference Figure 1-5 This utility model provides a rapid organic solvent extraction device for plant extraction: it includes a reaction vessel 1, a mounting cover 2, a condenser 4, a separator 5, and a collector 6. The mounting cover 2 is fitted onto the reaction vessel 1. A connecting pipe 3 is fixedly connected between the mounting cover 2 and the condenser 4. A mounting ring 21 is rotatably connected inside the mounting cover 2. A conical toothed ring 22 is fixedly fitted onto the inner wall of the mounting ring 21. Cleaning scrapers 25 are fixedly connected to both sides of the lower end face of the mounting ring 21. Stirring rods 26 are fixedly connected to the outer wall of the opposite side of the two cleaning scrapers 25. A guide pipe 51 is fixedly fitted into the middle of the separator 5. The lower end pipe of the condenser 4 is fitted into the guide pipe 51. A guide pipe 52 is fixedly fitted into one side of the separator 5 near the upper end. The collector 6 is located below the outlet of the guide pipe 52. A valve is rotatably installed on the guide pipe 52.

[0027] Multiple stirring rods 26 are provided, and the multiple stirring rods 26 are evenly distributed on the outer wall of two cleaning scrapers 25. The other side of the outer wall of the two cleaning scrapers 25 is slidably attached to the inner wall of the reactor 1. A motor 23 is fixedly connected to the outer wall of the mounting cover 2. A bevel gear 24 is fixedly sleeved at the output end of the motor 23. The bevel gear 24 meshes with the bevel gear ring 22. A steam inlet pipe 11 is fixedly connected to the side of the reactor 1 near the lower end face. A cold water inlet pipe 41 and a hot water outlet pipe 42 are fixedly sleeved on one side of the condenser 4. The cold water inlet pipe 41 is located below the hot water outlet pipe 42. When the cleaning scrapers 25 rotate, they not only clean the inner wall of the reactor 1, but also drive the stirring rods 26 to rotate and stir, so as to avoid uneven heating in the reactor 1.

[0028] Both sides of the upper end face of the reactor 1 are provided with mounting grooves 13. Both sides of the lower end face of the mounting cover 2 are fixedly connected with mounting blocks 27. The two mounting blocks 27 are respectively movably fitted into the two mounting grooves 13. The outer walls of the opposite sides of the two mounting blocks 27 are provided with slots 28. The outer walls of both sides of the reactor 1 are fixedly connected with fixing frames 14. The two fixing frames 14 are slidably connected with locking blocks 16. The locking blocks 16 are slidably fitted into the slots 28. The ends of the locking blocks 16 away from the mounting blocks 27 are respectively fixedly connected with pull rods 15 and springs. Spring 17 and pull rod 15 are connected to the fixed frame 14 at the other end and are fixedly connected to a pull cap. The pull cap drives the pull rod 15 to move, thereby driving the locking block 16 to disengage from the slot 28. This allows the mounting block 27 to be easily removed from the mounting slot 13, thus removing the mounting cover 2. The other end of spring 17 is fixedly connected to the inner wall of the fixed frame 14. Spring 17 is movably sleeved on the outer end of pull rod 15. Under natural force, spring 17 can ensure that the locking block 16 is sleeved in the slot 28, preventing the mounting block 27 from shaking and causing the mounting cover 2 to be unstable.

[0029] Steam is introduced into the reactor through the steam inlet pipe 11 to heat the liquid and increase the solvent evaporation rate. At the same time, the motor 23 drives the bevel gear 24 to rotate, which in turn drives the electric bevel gear ring 22 to rotate. This, in turn, drives the two cleaning scrapers 25 to rotate through the mounting ring 21. When the cleaning scrapers 25 rotate, they will drive the stirring rod 26 to stir, further improving the uniformity of liquid heating. The cleaning scrapers 25 also remove the precipitates on the inner wall of the reactor 1 in a timely manner to avoid affecting the reaction. This can effectively improve the extraction efficiency of organic solvents. Subsequently, the volatile components in the plant material enter the condenser to condense and become liquid, which flows into the guide pipe 51 and then enters the separator 5 for stratification. This process is convenient and time-saving.

[0030] Working principle: When in use, the mounting block 27 is aligned with the mounting groove 13 and inserted. Under the pressure of the inclined surface at the lower end of the mounting block 27, the locking block 16 moves towards the fixing frame 14 and compresses the spring 17. When the locking groove 28 moves to the position of the locking block 16, under the restoring force of the spring 17, the locking block 16 is just inserted into the locking groove 28, fixing the mounting block 27 in the mounting groove 13, thereby quickly installing the mounting cover 2 on the reactor 1. During the evaporation process, the starting motor 23 drives the bevel gear 24 to rotate, which in turn drives the bevel gear ring 22 to rotate, which in turn drives the two cleaning scrapers 25 to rotate through the mounting ring 21, cleaning and scraping away the debris adhering to the inner wall of the reactor 1 in time. At the same time, it drives the stirring rod 26 to rotate and stir, improving the uniformity of temperature distribution.

[0031] Later, by pulling the lever 15 to disengage the locking block 16 from the slot 28, the mounting cover 2 can be quickly removed from the reactor 1, making it convenient to manually clean the inner wall of the reactor 1, the cleaning scraper 25, and the stirring rod 26 for the next use.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
