Description

Technical Field

[0001] This utility model relates to a plant extraction device and belongs to the field of plant extraction technology. Background Technology

[0002] Natural plant extraction is a process of extracting beneficial components from natural plants using physical or chemical methods. It refers to using natural plants as raw materials and extracting various beneficial components through physical or chemical methods to provide raw material support for food, cosmetics, pharmaceuticals and other fields. These components can be single active ingredients or complex ingredients composed of multiple active ingredients. They are characterized by being natural, safe, non-toxic and without side effects, and have a wide range of applications in food, cosmetics and pharmaceuticals. However, most existing natural plant extraction methods use cold-press extraction to extract the juice of natural plants. This involves placing the natural plant at the bottom of a container and squeezing it out with a pressure plate to extract the juice.

[0003] During extraction, the pressed plant juice is poured into the extraction tank, and then the extractant is added. The solution inside the extraction tank is mixed by a stirring structure. After mixing, the solution is allowed to stand for a period of time to separate into layers, and the separated extract can then be separated. However, during the sedimentation and separation process, the extraction tank is occupied, and new solution can only be added after all the solution in the extraction tank has been drained, which affects the extraction efficiency. To address this, we propose a plant extraction device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a plant extraction device that solves the problem in the prior art where the extraction tank is occupied during the precipitation and stratification process, and new solution can only be added after all the solution in the extraction tank has been drained, which affects the extraction efficiency.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A plant extraction device includes an extraction tank. The interior of the extraction tank has a mixing chamber and a sedimentation chamber arranged sequentially from top to bottom. The mixing chamber and the sedimentation chamber are connected through a guide hole. A support plate is fixedly connected to the outer surface of the extraction tank. An electric push rod is fixedly connected to the support plate. A cover plate is fixedly connected to the end of the electric push rod away from the support plate. A stirring shaft is rotatably connected inside the cover plate. A sealing assembly is installed at the bottom end of the stirring shaft. A filter screen is fixedly connected to the outer surface of the stirring shaft. Stirring blades are fixedly connected to the outer surface of the filter screen. A motor is fixedly connected to the top end of the stirring shaft.

[0007] By adopting the above technical solution, after the feed liquid and extractant are added into the extraction tank, the motor drives the stirring shaft to rotate, which can stir and mix the feed liquid and extractant in the mixing chamber. After the mixing is completed, the operator starts the electric push rod, which moves the cover plate upward. The sealing component is then pulled out from the guide hole, and the mixed solution in the mixing chamber flows into the sedimentation chamber through the guide hole. After all the mixed solution has flowed into the sedimentation chamber, the electric push rod can be started again, which moves the cover plate downward. The cover plate seals the extraction tank, and the sealing component is inserted into the guide hole to seal and block the guide hole. The operator can continue to add feed liquid and extractant into the mixing chamber of the extraction tank to mix the solution. At the same time, the solution in the sedimentation chamber can precipitate and separate into layers. After the separation is completed, the extractant is discharged, and the mixed solution can be flowed into the sedimentation chamber again. Since the solution mixing can be completed in advance during the solution sedimentation process, the mixed solution can be replenished more quickly, which can effectively improve the extraction efficiency.

[0008] The present invention is further configured such that: the extraction tank is rotatably connected to the inside of the support via a rotating shaft, and a gear set is installed at one end of the rotating shaft away from the extraction tank; a base plate frame is fixedly connected to the bottom end of the support; the gear set includes a gear one connected to the rotating shaft, a gear two meshing with the outer surface of the gear one, the gear two being fixedly connected to the output end of the motor two; a motor frame is fixedly connected to one side of the support, and the motor two is fixedly mounted on the motor frame.

[0009] By adopting the above technical solution, after the extract has been separated into layers, the staff can start motor two, which can drive gear two to move and drive gear one to rotate, so that the shaft can rotate and the extraction tank can be flipped over to facilitate the discharge of the upper layer of extract.

[0010] The present invention is further configured such that: an observation window is provided on the outer surface of the extraction tank, a fixing frame is fixedly connected to the upper surface of the cover plate, and a motor is fixedly connected to the inner top wall of the fixing frame.

[0011] By adopting the above technical solution, staff can observe the solution level inside the extraction tank through the observation window on the extraction tank.

[0012] The present invention is further configured such that: a lower drain pipe is fixedly connected to the bottom of the extraction tank, an upper drain pipe is fixedly installed on the outer surface of the extraction tank, and control valves are installed inside both the lower drain pipe and the upper drain pipe.

[0013] By adopting the above technical solution, when it is necessary to discharge the extract, the staff can open the control valve on the lower drain pipe to discharge the lower layer of extract through the lower drain pipe. After turning the extraction tank over, the control valve inside the upper drain pipe can be opened to discharge the upper layer of solution from the upper drain pipe.

[0014] The present invention is further configured such that: a liquid inlet pipe and an extractant inlet pipe are provided on the cover plate, and a sealing cap is threadedly connected to the outer surface of both the liquid inlet pipe and the extractant inlet pipe.

[0015] By adopting the above technical solution, workers can add liquid and extractant into the mixing chamber of the extraction tank through the liquid inlet pipe and the extractant inlet pipe.

[0016] The present invention is further configured such that: the sealing component includes a fixed block, the stirring shaft is rotatably connected inside the fixed block through a sealing bearing, and a rubber sealing plug is fixedly connected to the lower surface of the fixed block.

[0017] By adopting the above technical solution, after the rubber sealing plug is inserted into the guide hole, the position of the rubber sealing plug can be stabilized, and the stirring shaft can be guaranteed to be free from interference during rotation.

[0018] The beneficial effects of this invention are as follows: After the feed liquid and extractant are added to the extraction tank, the motor drives the stirring shaft to rotate, which can stir and mix the feed liquid and extractant in the mixing chamber. After mixing, the operator starts the electric push rod, which moves the cover plate upward, and the sealing component is pulled out from the guide hole. The mixed solution in the mixing chamber will then flow into the sedimentation chamber through the guide hole. After all the mixed solution has flowed into the sedimentation chamber, the electric push rod can be started again, which moves the cover plate downward, sealing the extraction tank. The sealing component is then inserted into the guide hole, sealing and blocking the guide hole. The operator can continue to add feed liquid and extractant to the mixing chamber inside the extraction tank to mix the solution. At the same time, the solution in the sedimentation chamber can precipitate and separate into layers. After separation, the operator drains the extract and then the mixed solution can flow back into the sedimentation chamber. Since the mixing of the solution can be completed in advance during the sedimentation process, the mixed solution can be replenished more quickly, which can effectively improve the extraction efficiency.

[0026] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0027] Example 1

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a plant extraction device includes an extraction tank 1. The interior of the extraction tank 1 has a mixing chamber 2 and a sedimentation chamber 3 arranged sequentially from top to bottom. The mixing chamber 2 and the sedimentation chamber 3 are connected through a guide hole 4. A support plate 5 is fixedly connected to the outer surface of the extraction tank 1, and an electric push rod 6 is fixedly connected to the support plate 5. A cover plate 7 is fixedly connected to the end of the electric push rod 6 away from the support plate 5. A sealing ring is fixedly connected to the side of the cover plate 7 facing the extraction tank 1. When the cover plate 7 contacts the extraction tank 1, it can seal the extraction tank 1, ensuring that the water inside the extraction tank 1 will not leak out during the inversion process. A stirring shaft 8 is rotatably connected inside the cover plate 7. The stirring shaft 8 is installed inside the cover plate 7 through a sealed bearing. During the stirring process of the solution, the cover plate 7 can seal the extraction tank 1 to ensure that no liquid will spill out. A sealing assembly is installed at the bottom of the stirring shaft 8. The sealing assembly includes a fixing block 9. The stirring shaft 8 is rotatably connected inside the fixing block 9 through a sealed bearing. A rubber sealing plug 18 is fixedly connected to the lower surface of the fixing block 9. After the rubber sealing plug 18 is inserted into the guide hole 4, it can stabilize the position of the rubber sealing plug 18 and ensure that the stirring shaft 8 is not interfered with during rotation.

[0029] After the feed solution and extractant are added into the extraction tank 1, motor 12 drives the stirring shaft 8 to rotate, which stirs and mixes the feed solution and extractant in the mixing chamber 2. After mixing is complete, the operator starts the electric push rod 6, which moves the cover plate 7 upward, causing the sealing component to be pulled out from the guide hole 4. The mixed solution in the mixing chamber 2 then flows into the sedimentation chamber 3 through the guide hole 4. After all the mixed solution has flowed into the sedimentation chamber 3, the electric push rod 6 can be started again, moving the cover plate 7 downward. The cover plate 7 then moves the extractant downward. Once barrel 1 is sealed, the sealing component is inserted into the guide hole 4 to seal and block the guide hole 4. The operator can continue to add the material liquid and extractant into the mixing chamber 2 inside the extraction barrel 1 to mix the solution. At the same time, the solution in the sedimentation chamber 3 can precipitate and separate into layers. After the separation is completed, the operator drains the extract liquid and then flows the mixed solution back into the sedimentation chamber 3. Since the solution mixing can be completed in advance during the solution sedimentation process, the mixed solution can be replenished more quickly, which can effectively improve the extraction efficiency.

[0030] like Figure 1 and Figure 3 As shown, a filter screen 10 is fixedly connected to the outer surface of the stirring shaft 8. When the liquid and extractant are added into the extraction tank 1, the liquid and extractant will pass through the filter screen 10 and fall into the mixing chamber 2. The filter screen 10 can filter the liquid and extractant to ensure that the extraction solution is cleaner. When the operator starts the electric push rod 6, the cover plate 7 is moved, which can move the filter screen 10 upward and remove it from the mixing chamber 2. The operator can clean the debris on the filter screen 10. The stirring blade 11 is fixedly connected to the outer surface of the filter screen 10. During the rotation of the stirring shaft 8, the filter screen 10 will be rotated. The stirring blade 11 can hold the liquid and the top of the stirring shaft 8. A motor 12 is fixedly connected to the top of the stirring shaft 8. An observation window 20 is provided on the outer surface of the extraction tank 1. The observation window 20 is divided into upper and lower parts. The upper observation window 20 can observe the condition inside the mixing chamber 2, and the lower observation window 20 can observe the condition of the solution inside the sedimentation chamber 3. A fixing frame 21 is fixedly connected to the upper surface of the cover plate 7. A motor 12 is fixedly connected to the inner top wall of the fixing frame 21.

[0031] like Figure 1 and Figure 6As shown, the extraction tank 1 is rotatably connected to the inside of the support 13 via a rotating shaft. A gear set is installed at the end of the rotating shaft away from the extraction tank 1. A base plate frame 14 is fixedly connected to the bottom end of the support 13. The gear set includes a gear 15 connected to the rotating shaft, a gear 16 meshing with the outer surface of the gear 15, and a fixed connection between the gear 16 and the output end of the motor 17. A motor frame 19 is fixedly connected to one side of the support 13, and the motor 17 is fixedly installed on the motor frame 19. After the extraction liquid has separated into layers, the operator starts the motor 17. The motor 17 can drive the gear 16 to move, drive the gear 15 to rotate, which can rotate the rotating shaft and flip the extraction tank 1 to facilitate the discharge of the upper layer of extraction liquid.

[0032] like Figure 2 and Figure 3 As shown, a lower drain pipe 22 is fixedly connected to the bottom of the extraction tank 1, and an upper drain pipe 23 is fixedly installed on the outer surface of the extraction tank 1. Both the lower drain pipe 22 and the upper drain pipe 23 are equipped with control valves. The cover plate 7 is provided with a liquid inlet pipe 24 and an extractant inlet pipe 25. The outer surfaces of the liquid inlet pipe 24 and the extractant inlet pipe 25 are threaded with sealing caps. When the extractant needs to be discharged, the operator opens the control valve on the lower drain pipe 22, and the lower layer of extractant can be discharged through the lower drain pipe 22. After the extraction tank 1 is turned over, the control valve inside the upper drain pipe 23 is opened, and the upper layer of solution can be discharged from the upper drain pipe 23. The operator can add liquid and extractant into the mixing chamber 2 of the extraction tank 1 through the liquid inlet pipe 24 and the extractant inlet pipe 25.

[0033] When solution extraction is required, the pressed plant extract and extractant are first introduced into the mixing chamber 2 through the extractant inlet pipe 24 and the extractant inlet pipe 25. The sealing cap is tightened, and the motor 12 is started to rotate the stirring shaft 8, which stirs and mixes the extractant and plant extractant inside the mixing chamber 2. After mixing, the electric push rod 6 is activated, which moves the cover plate 7 upward, causing the sealing assembly to be pulled out from the guide hole 4. The mixed solution inside the mixing chamber 2 then flows into the sedimentation chamber 3 through the guide hole 4. After all the mixed solution has flowed into the sedimentation chamber 3, the electric push rod 6 is activated again, moving the cover plate 7 downward and sealing the extraction tank 1. The sealing component is inserted into the guide hole 4 to seal and block the guide hole 4. The operator can continue to add the material liquid and extractant into the mixing chamber 2 inside the extraction tank 1 to mix the solution. At the same time, the solution in the sedimentation chamber 3 can precipitate and separate into layers. After the separation is completed, the operator can first open the control valve on the lower drain pipe 22 to discharge the extract liquid through the lower drain pipe 22. Then the operator starts the motor 2 17, which drives the gear 2 16 to move and drive the gear 1 15 to rotate, which can rotate the shaft and flip the extraction tank 1. Open the control valve inside the upper drain pipe 23 to discharge the upper layer solution from the upper drain pipe 23. Then the extraction tank 1 is restored to the vertical position.
