Description

Technical Field

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

[0002] Plant extraction is a method of extracting active ingredients from plants. The basic principle is to use solvents to extract the target substance from the plant matrix to obtain concentrated active ingredients. This method is also called liquid-solid extraction. It uses volatile organic solvents to transfer certain components in the raw materials into the solvent phase, and then recovers the organic solvents by evaporation, distillation, etc., so as to obtain the desired relatively pure extraction components.

[0003] In the fields of traditional Chinese medicine, health products, cosmetics, etc., extraction devices are used to extract active ingredients from plant raw materials. However, most of the existing extraction devices are closed structures. After the extraction is completed, the residue is not easy to be discharged, which makes it difficult to recover the residue. The original liquid contained in the recovered plant residue needs to be transferred to other equipment for re-extrusion and filtration, which increases the production input cost. At the same time, during the extraction process, the plant raw materials will float on the surface of the solvent due to buoyancy, and it is difficult to completely immerse them in the solvent, which increases the extraction time and affects the extraction efficiency. Therefore, there is an urgent need for a plant raw material extraction device that can completely immerse the plant raw materials and facilitate the recovery of plant residues. Utility Model Content

[0018] 2. A transparent inspection window is provided on the front side of the annular surface of the leaching tank in the utility model. Through the transparent inspection window, the operator can directly observe the leaching process inside the leaching tank without opening the end cover, and can monitor the progress and effect of the leaching in real time.

[0022] 6. The surface of the positioning sleeve is evenly provided with multiple groups of through holes, which allow the liquid in the leaching process to pass through, ensuring that the solvent in the leaching tank can smoothly enter the isolation mesh cylinder from the bottom, and can ensure that the raw materials are fully and evenly soaked. A guide plate with an upwardly convex arc structure is fixed at the bottom of the leaching tank, and the guide plate is located inside the positioning sleeve.

[0023] 7.

The design of the slide block and the slide groove provides guidance and stability for the up and down movement of the sleeve on the fixed support rod, ensuring that the pressure plate will not rotate relative to the fixed support rod during the movement. When the sleeve moves, the slide block slides along the slide groove to ensure that the sleeve will not deviate from the fixed support rod, thereby maintaining the stability and accuracy of the entire structure.

[0041] A positioning sleeve 17 is fixedly provided at the bottom of the inner wall of the leaching tank 6, and a circle of supporting plates 26 are provided on the inner wall of the positioning sleeve 17. The bottom of the isolation net tube 13 is inserted into the positioning sleeve 17 and placed on the supporting plates 26. This design can support the isolation net tube 13 from the bottom through the positioning sleeve 17 and the supporting plates 26, further improving the stability of the isolation net tube 13.

[0042] The surface of the positioning sleeve 17 is evenly provided with multiple groups of through holes 171, and the multiple groups of through holes 171 allow the liquid in the leaching process to pass through, so as to ensure that the solvent in the leaching tank 6 can smoothly enter the isolation mesh tube 13 from the bottom, and the raw materials can be fully and evenly soaked. A guide plate 25 with an upwardly convex arc structure is fixedly provided at the bottom of the leaching tank 6, and the guide plate 25 is located inside the positioning sleeve 17. The guide plate 25 can guide the liquid to flow around, so that the liquid can completely flow out from the liquid outlet pipe 10 when discharging the liquid, and reduce the liquid residue.

[0043] The upper side of the sleeve 24 is fixedly connected with a sleeve 22, and the sleeve 22 is sleeved on the fixed support rod 30. The upper side of the ring surface of the fixed support rod 30 is provided with an external thread 28, and the fixed support rod 30 is screwed with a nut 21, and the ring surface of the sleeve 24 is evenly provided with multiple groups of handles 27.

Next, the connecting sleeve 22 of the pressing plate 23 is sleeved on the fixed support rod 30, and the plant material is pressed down by the gravity of the pressing plate 23 itself to prevent the plant material from floating up, so as to ensure that the plant material can be completely immersed in the solvent. Cover the end cover 3, open the solenoid valve 1 and inject an appropriate amount of solvent into the extraction tank 6 through the water injection pipe 2. Then start the electric heater 12 to heat the solvent in the extraction tank 6 and start the extraction process. During the extraction process, the operator can observe the progress and effect of the extraction in real time through the transparent inspection window 7. When the extraction is completed, turn off the electric heater 12, open the valve 11, and discharge the extract through the liquid outlet pipe 10. At this time, the design of the guide plate 25 helps the liquid to flow out completely and reduce residue. After the extract is discharged, the operator lifts the isolation net tube upward for a distance through the handle 14, so that the support plate 16 is placed on the limit baffle 18, and the support plate 16 is positioned through the positioning hole 19 and the positioning block 20. Then the operator assembles the nut 21 to the fixed support rod 30 through the external thread 28, rotates the nut 21, and moves it downward along the fixed support rod 30, pushing the sleeve 22 and the sleeve 24 downward, thereby driving the pressing plate 23 to squeeze the plant residue in the isolation net tube 13. The squeezed liquid flows out through the holes on the isolation net tube 13, and the residue remains in the isolation net tube 13. After the extrusion is completed, the operator takes the isolation net tube 13 out of the leaching tank 6 through the handle 14, and finally cleans out the residue in the isolation net tube 13.
