Description

Technical Field

[0001] The utility model relates to the technical field of plant extraction, in particular to a plant extraction leaching apparatus. Background Art

[0002] A plant extraction leaching apparatus is a professional experimental device. Its main function is to impregnate plant materials with a specific solvent, thereby effectively extracting the active ingredients or effective components in the plants. This process is of great significance for multiple fields such as drug research and development, health product production, and food additive manufacturing, and helps to improve the quality and effect of products.

[0003] However, for the currently existing plant extraction leaching apparatuses, the solvent is usually sprayed onto the surface of the plants, and then natural sedimentation and stirring are relied on to promote extraction. However, this method has the problems of slow extraction speed and low efficiency. Many plant materials fail to be fully mixed with the solvent during the extraction process, thus affecting the extraction quality.

[0004] Therefore, in view of the situation that the existing plant extraction leaching apparatuses have slow extraction speed and low efficiency, which in turn affect the extraction quality, a plant extraction leaching apparatus can be designed. Through a bevel gear transmission structure, a belt transmission structure, and a double filtration structure, while enabling the full mixing of plant materials and the solvent, the extraction quality is also improved. Summary of the Utility Model

[0005] In order to overcome the problems of slow extraction speed and low efficiency of the plant extraction leaching apparatus, which in turn affect the extraction quality.

[0006] The technical solution of the utility model is as follows: A plant extraction leaching apparatus includes a leaching tank, support feet, a plant feed inlet, a solvent inlet, a receiving tank, a limiting frame, a rotating assembly, a first filter plate, a guiding frame, a second filter plate, and a discharge pipe; Four support feet for support are fixedly connected to the lower end of the receiving tank. A circular through-hole is penetrated and opened at the upper end of the receiving tank. A rotating assembly adapted to the circular through-hole is installed in the receiving tank. The upper end of the rotating assembly is fixedly connected to a limiting frame. The leaching tank is adapted to the limiting frame and is installed at the upper end of the rotating assembly through the limiting frame. The plant feed inlet is installed on the left side of the upper end of the leaching tank, and the solvent inlet is installed on the right side of the upper end of the leaching tank. A first filter plate is installed in the leaching tank. The guiding frame is installed at the lower end of the first filter plate. A second filter plate adapted to the port is installed at the lower outlet of the guiding frame. The discharge pipe is installed at the lower end of the second filter plate.

[0007] Preferably, the leaching tank is the main container in the plant extraction process, used to hold plant materials and solvents. It is adapted to the limit frame to ensure stability during rotation. On the left side of the upper end of the leaching tank, there is a plant feed inlet for adding plant materials to be extracted, and on the right side of the upper end, there is a solvent inlet for adding extraction solvents. The receiving tank is located below the leaching tank and is used to install the rotating assembly. The rotating assembly can drive the leaching tank to rotate, so that the solvent and plants can be fully mixed. The first filter plate is used to preliminarily filter impurities in the extract, block larger solid particles, and the guiding frame is used to guide the extract to flow to the second filter plate.

[0009] Preferably, the rotating assembly includes a support shaft and a turntable; the lower end of the support shaft is rotatably connected to the first rotating support seat, and the upper end of the support shaft is fixedly connected to the turntable. The support shaft is the main load-bearing component of the rotating assembly, responsible for transmitting the rotational motion of the motor to the turntable and the leaching tank. The turntable rotates as the support shaft rotates. The turntable has a relatively large diameter and strength, and is used to support the leaching tank and the plant materials and solvents inside it.

A second coupling is installed at the right end of the first rotating shaft and is connected to the output shaft of the second rotary motor through the second coupling. The left end of the first rotating shaft is rotatably connected to the second rotary support seat at the front side. The second rotary support seat ensures that the first rotating shaft and the second rotating shaft can rotate smoothly, and at the same time bear the force and vibration generated during the stirring process. The second rotary motor is the power source for driving the stirring roller to rotate. It transmits torque through the output shaft, thereby driving the first rotating shaft, the second rotating shaft and the stirring rollers on them to rotate. The first rotating shaft is tightly connected to the output shaft of the second rotary motor through the second coupling, and then drives the driving wheel to rotate.

[0012] Preferably, the left end of the second rotating shaft is rotatably connected to the second rotary support seat at the rear side. The right end of the second rotating shaft extends to the right end of the leaching tank. Stirring rollers are fixedly connected to the outer walls of both the first rotating shaft and the second rotating shaft. The second rotating shaft and the first rotating shaft jointly drive the stirring rollers to rotate. The stirring rollers rotate as the first rotating shaft and the second rotating shaft rotate. Its function is to stir the plant materials and the solvent, promote the mixing between them, and thus improve the extraction efficiency.

[0013] Preferably, a driving wheel is fixedly connected to the outer wall at the right end of the first rotating shaft, and a driven wheel is fixedly connected to the outer wall at the right end of the second rotating shaft.

[0027] Please refer to Figure 2 and Figure 3, in this embodiment, second rotating support seats 20 are symmetrically and fixedly connected to the inner wall at the left end of the leaching tank 1 before and after. A second rotating motor 21 is installed at the right end of the leaching tank 1. A second coupling 23 is installed at the right end of the first rotating shaft 22 and is connected to the output shaft of the second rotating motor 21 through the second coupling 23. The left end of the first rotating shaft 22 is rotatably connected to the second rotating support seat 20 at the front side.

Next, start the first rotating motor 13 and the second rotating motor 21. The start of the first rotating motor 13 will drive the connecting shaft 14 to rotate, and then the driving bevel gear 18 will rotate. Through the meshing action between the gears, the driven bevel gear 19 is driven to rotate, so that the support shaft 16 and the turntable 17 start to rotate, and thus the leaching tank 1 also rotates accordingly;

[0029] At the same time, the start of the second rotating motor 21 will drive the first rotating shaft 22 to rotate. Under the belt 28 transmission action between the first rotating shaft 22 and the second rotating shaft 24, the second rotating shaft 24 also starts to rotate, so that the stirring rollers 25 on the first rotating shaft 22 and the second rotating shaft 24 start to rotate. The rotation of these stirring rollers 25 will stir the plant materials and the solvent, promote the mixing between them, and thus improve the extraction efficiency;

[0030] Finally, the extract will pass through the double filtration of the first filter plate 7 and the second filter plate 9 to ensure the purity of the extract, and the filtered extract will be discharged from the discharge pipe 10.
