Some of the evaporated gas condenses into liquid beads and adheres to the inner wall of the heating barrel, and will drop back into the concentrated liquid again, affecting the purity of the concentrated liquid. For this reason, this application proposes a plant extraction and concentration device. Utility Model Content

[0032] Embodiment 1

[0033] As Figures 1-3As shown, a plant extraction and concentration device proposed in the present application includes a concentration cylinder 1 and a heater 3 arranged inside the concentration cylinder 1. The outer wall of the heater 3 and the inner wall of the concentration cylinder 1 form an annular heating chamber, so that the heater 3 can fully contact the concentrated liquid and can evenly heat the concentrated liquid, thereby improving the concentration efficiency. The side wall of the concentration cylinder 1 is connected to a liquid inlet 2 located outside the heating chamber. A sealing cover is provided at the upper end of the liquid inlet 2, and plant liquid is added to the interior of the concentration cylinder 1 through the liquid inlet 2. It also includes: a steam collection component 5 arranged at the upper end of the heater 3, which is used to collect and discharge evaporated liquid droplets to prevent the evaporated liquid from condensing into liquid droplets and dripping into the concentrated liquid.

[0034] Specifically, the steam collecting assembly 5 includes an attachment platform 51 fixedly connected to the upper end of the heater 3, a first liquid collecting tank 52 is arranged outside the bottom end of the attachment platform 51, a second liquid collecting tank 53 located at the same horizontal plane as the first liquid collecting tank 52 is arranged on the inner wall of the concentrator cylinder 1, and a liquid guide tank 54 is connected between the first liquid collecting tank 52 and the second liquid collecting tank 53, so that the first liquid collecting tank 52 and the second liquid collecting tank 53 are connected, so that the liquid in the first liquid collecting tank 52 can flow into the second liquid collecting tank 53. The attachment platform 51 is conical, and its outer side surface is an inclined surface, so that the liquid droplets attached to its outer side wall can smoothly slide into the first liquid collecting tank 52.

[0035] The outer side of the concentrating cylinder 1 is connected to a drain pipe 9 located outside the second liquid collecting tank 53, and the drain pipe 9 is connected to the second liquid collecting tank 53 for discharging the evaporated collected liquid. The bottom end of the concentrating cylinder 1 is connected to a discharge pipe 4 connected to the heating chamber, and the discharge pipe 4 and the drain pipe 9 are both provided with control valves for discharging the concentrated liquid.

[0036] The working principle of this embodiment is as follows: the plant liquid is added into the interior of the concentration cylinder 1 through the liquid inlet 2, the highest liquid level is located below the first liquid collecting tank 52, the heater 3 is started to heat the concentrated liquid in the concentration cylinder 1, and after the plant liquid is heated, the volatile substances inside it will adhere to the inner wall of the concentration cylinder 1 and the outer wall of the attachment platform 51 in the form of steam, and the attached steam will condense into liquid droplets and then slide into the first liquid collecting tank 52 and the second liquid collecting tank 53. The valve on the drain pipe 9 can be opened to discharge the collected liquid to the outside, effectively preventing the water droplets condensed from the steam from dripping into the concentrated liquid again, thereby ensuring the concentration effect.

[0037] Embodiment 2

[0038] The plant extraction and concentration device proposed in the present utility model is compared with the first embodiment. Figures 3-4 As shown, this embodiment also includes: the upper end of the steam collecting component 5 is provided with a drainage auxiliary component 6 to assist in discharging the evaporated condensed liquid droplets and to stir the plant liquid in the concentration cylinder 1 so that the liquid can be evenly heated.

[0039] Specifically, the liquid drainage auxiliary member 6 includes a first scraper 63 and a second scraper 64 which are respectively slidably connected inside the first liquid collection tank 52 and the second liquid collection tank 53. The upper ends of the first scraper 63 and the second scraper 64 are fixedly connected together with a connecting rod 62. The upper end of the connecting rod 62 is fixedly connected with a transmission rod 61. The transmission rod 61 is of a "ㄱ" shape structure (due to the perspective problem, the complete structure of the transmission rod 61 is not shown in the figure). A servo motor 8 is installed at the upper end of the concentration cylinder 1. The output shaft of the servo motor 8 is fixedly connected with a rotating shaft that rotates on the upper end of the steam collection assembly 5. The upper end edge of the transmission rod 61 is fixedly connected with the rotating shaft. By the rotation of the rotating shaft, the transmission rod 61 can be driven to move in an arc angle inside the concentration cylinder 1. It should be noted that the rotation angle of the transmission rod 61 does not exceed 360 degrees because a liquid guiding groove 54 is provided between the first liquid collection tank 52 and the second liquid collection tank 53. When the transmission rod 61 slides to both sides of the liquid guiding groove 54, it will move back. A plurality of stirring rods 7 are fixedly connected to the lower surface of the connecting rod 62. All the plurality of stirring rods 7 extend to the bottom of the concentration cylinder 1. When the connecting rod 62 moves, it can drive the plurality of stirring rods 7 to move in the heating chamber, stirring the heated liquid to make the liquid evenly heated.

[0040] The working principle of this embodiment is as follows: When concentrating the liquid, the servo motor 8 is started to make the output shaft of the servo motor 8 rotate forward and backward reciprocally. Then, the connecting rod 62 is driven by the transmission rod 61 to swing reciprocally inside the concentration cylinder 1. Finally, the first scraper 63 and the second scraper 64 respectively slide reciprocally in the first liquid collection tank 52 and the second liquid collection tank 53, scraping the liquid in the first liquid collection tank 52 and the second liquid collection tank 53 to the liquid guiding groove 54, and finally discharging it through the drain pipe 9. At the same time, when the connecting rod 62 swings, it drives the plurality of stirring rods 7 to move in the heating chamber, stirring the heated liquid to make the liquid quickly and evenly heated, improving the evaporation and concentration efficiency.
