Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plant extract extraction, and more specifically, to a plant extract extraction device. Background Technology
[0002] Plant extract refers to a high-purity liquid containing plant active ingredients obtained by collecting pollution-free natural plants from around the world and using the most advanced international secondary high-efficiency plant purification and separation technologies – “high-performance liquid chromatography” and “liquid phase ultra-micro membrane separation technology”.
[0003] The extraction of plant extracts typically involves first soaking the plants in an extractant solution to extract the active ingredients. The extract is then subjected to further separation and purification as needed. Therefore, the initial extraction steps require thorough mixing and stirring of the extractant with the plants before the extract is squeezed out. This process necessitates sufficient contact and soaking time between the extractant and the plants, and involves the use of stirring, filtering, and squeezing devices. The process is complex, time-consuming, and increases equipment and labor costs to some extent. Utility Model Content

[0006] Furthermore, the feeding device is located above the pressure plate.
[0007] Furthermore, the pressure plate is a cone shape, smaller at the top and larger at the bottom.
[0008] Furthermore, the edge of the pressure plate has a horizontal annular structure.
[0009] Furthermore, the outer wall of the inner tank is provided with an annular discharge trough, the discharge trough is connected to a discharge pipe, and the end of the discharge pipe away from the discharge trough is connected to a storage tank.
[0010] Furthermore, the discharge trough is inclined, and the discharge pipe is connected to the lower end of the discharge trough.
[0011] Furthermore, the first driving device includes a first hydraulic cylinder arranged vertically downwards and a bracket for supporting the first hydraulic cylinder; the telescopic rod of the first hydraulic cylinder passes through the cover plate and is fixedly connected to the upper side of the pressure plate, and the telescopic rod of the first hydraulic cylinder is slidably connected to the pressure plate in a sealed manner; the second driving device includes a second telescopic cylinder arranged vertically downwards and connected to the bracket; the telescopic rod of the second telescopic cylinder is fixedly connected to the upper side of the cover plate.
[0012] Furthermore, the feeding device includes a sleeve passing through the outer wall of the outer tank, a feeding pipe slidably disposed in the sleeve, and an electric push rod connected to the side wall of the feeding pipe; the electric push rod is connected to the side wall of the sleeve, and the telescopic rod of the electric push rod is connected to the side wall of the feeding pipe; the sleeve is disposed above the inner tank, and the sleeve is inclined and faces the inner tank.
[0013] Furthermore, a hollow liquid storage box is fixedly provided on the lower side of the cover plate, and multiple drainage holes are opened on the lower side of the liquid storage box.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the plant extract extraction equipment of this utility model uses a second driving device to lift the cover plate, exposing the upper part of the inner tank.

The inner tank is then sealed with the cover plate, and the first driving device drives the pressure plate to slowly move up and down within the inner tank. As the pressure plate moves downward, it squeezes the extract in the lower part of the inner tank, causing it to pass through the filter holes on the pressure plate under pressure and rush to the top of the pressure plate, impacting the plant fragments above the pressure plate, thus achieving the desired effect. The stirring action of the plant fragments and the extract, along with the upward movement of the pressure plate, compresses the plant fragments through the pressure plate and cover plate, squeezing out the extract and the original plant sap. This repeated up-and-down movement of the pressure plate ensures that the original plant sap is fully extracted into the extract. Finally, the plant fragments are squeezed again by the pressure plate and cover plate, and the extract is discharged through a drain pipe during the squeezing process. The extract can then be further separated and purified. This method allows for highly efficient and thorough extraction of the original plant sap without the need for a stirring device, reducing the need for compression and filtration equipment, thus improving production efficiency and reducing production costs to a certain extent.

Detailed Implementation
[0022] Example
[0023] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 6As shown, the plant extract device of this embodiment includes an outer tank 11, an inner tank 12 fixed inside the outer tank 11 and open at the top, a feeding device 20 connected to the inner tank 12, a pressure plate 13 slidably disposed in the inner tank 12, filter holes 110 opened on the pressure plate 13, a first driving device 30 for driving the pressure plate 13 to rise and fall, a cover plate 14 covering the upper end of the inner tank 12, and a second driving device 40 for driving the cover plate 14 to rise and fall; the outer wall of the pressure plate 13 is slidably connected to the inner wall of the inner tank 12, and the inner tank 12 is also connected to an inlet pipe 18 and an outlet pipe 19. Specifically, during use, the second drive device 40 lifts the cover plate 14, exposing the upper part of the inner tank 12. Then, the mixture of processed plant fragments and extract is fed into the inner tank 12 through the feeding device 20, and the extract is pumped into the inner tank 12 through the liquid inlet pipe 18. The inner tank 12 is then closed with the cover plate 14. The first drive device 30 drives the pressure plate 13 to slowly move up and down within the inner tank 12. As the pressure plate 13 moves downward, it squeezes the extract in the lower part of the inner tank 12, causing the extract in the lower part of the inner tank 12 to pass through the filter holes 110 on the pressure plate 13 under pressure and rush to the top of the pressure plate 13, impacting the plant fragments above the pressure plate 13, thus achieving the desired effect of processing the plant fragments and extract. During the liquid extraction process, the pressure plate 13 moves upward, and the plant fragments are squeezed by the pressure plate 13 and the cover plate 14, squeezing out the extract from the plant fragments and also squeezing out the original plant liquid. Through the repeated up-and-down movement of the pressure plate 13, the original plant liquid in the plant fragments can be fully squeezed into the extract. Finally, the plant fragments are squeezed by the pressure plate 13 and the cover plate 14, and the extract is discharged through the drain pipe 19 during the squeezing process. The extract can then be separated and purified. This method can extract the original plant liquid very efficiently and fully without the need for a stirring device, and it can also reduce the use of a squeezing and filtering device, which can improve production efficiency and reduce production costs to a certain extent.
[0024] In this embodiment, the feeding device 20 is positioned above the pressure plate 13. Specifically, when plant fragments are fed into the inner tank 12 via the feeding device 20, the plant fragments can fall above the pressure plate 13, and the diameter of the filter holes 110 above the pressure plate 13 is smaller than the size of the plant fragments.
[0025] In this embodiment, the pressure plate 13 is conical, wider at the bottom and narrower at the top. The edge of the pressure plate 13 is a horizontal annular structure. The outer wall of the inner tank 12 is provided with an annular discharge groove 15, which is connected to a discharge pipe 16. The end of the discharge pipe 16 furthest from the discharge groove 15 is connected to a storage tank 17. Specifically, the horizontal structure at the edge of the pressure plate 13 prevents plant fragments from getting stuck between the pressure plate 13 and the inner tank 12. The conical shape of the pressure plate 13 allows the plant fragments to be squeezed before being discharged from the inner tank 12. Then, the second driving device 40 drives the cover plate 14 upwards, and the first driving device 30 drives the pressure plate 13 upwards, so that the lower end of the pressure plate 13 is positioned at the upper end of the inner tank 12 (as shown in the attached diagram). Figure 3 As shown), the cover plate 14 continues to move upward until it no longer squeezes the plant fragments. Under the action of gravity, the plant fragments slide off the pressure plate 13 onto the outer wall of the inner tank 12 and enter the discharge trough 15. Through the discharge trough 15 and the discharge pipe 16, they enter the storage tank 17 for storage. In the storage tank 17, the extract is added for long-term soaking treatment to fully extract the original juice from the plant.
[0026] In this embodiment, the discharge trough 15 is inclined, and the discharge pipe 16 is connected to the lower end of the discharge trough 15. A hollow liquid storage box 111 is fixedly provided on the lower side of the cover plate 14. The liquid storage box 111 has multiple drainage holes on its lower side. The liquid storage box 111 is connected to a liquid guide pipe 112, and the liquid guide pipe 112 is connected to a liquid supply device. The liquid storage box 111 is located directly above the pressure plate 13, and the liquid guide pipe 112 passes through the cover plate 14 and is fixedly connected to the cover plate 14. Specifically, this allows the squeezed plant fragments to enter the storage tank 17 more fully and quickly through the discharge trough 15. Furthermore, the squeezed plant fragments may stick together and be difficult to separate. Therefore, the extract can be pumped into the liquid supply tube 112 through the liquid supply device. The extract enters the liquid storage box 111 and is discharged through the drain hole on the lower side of the liquid storage box 111. Then it flows to the middle of the upper part of the squeezing plate 13 to flush the plant fragments on the squeezing plate 13, so that they can slide off the squeezing plate 13 better.
[0027] In this embodiment, the first driving device 30 includes a first hydraulic cylinder 31 arranged vertically downwards and a bracket 32 for supporting the first hydraulic cylinder 31; the telescopic rod of the first hydraulic cylinder 31 passes through the cover plate 14 and is fixedly connected to the upper side of the pressure plate 13, and the telescopic rod of the first hydraulic cylinder 31 is slidably connected to the pressure plate 13 in a sealed manner; the second driving device 40 includes a second telescopic cylinder arranged vertically downwards and connected to the bracket 32; the telescopic rod of the second telescopic cylinder is fixedly connected to the upper side of the cover plate 14.
[0028] The feeding device 20 in this embodiment includes a sleeve 21 passing through the outer wall of the outer tank 11, a feeding pipe 22 slidably disposed in the sleeve 21, and an electric push rod 23 connected to the side wall of the feeding pipe 22; the electric push rod 23 is connected to the side wall of the sleeve 21, and the telescopic rod of the electric push rod 23 is connected to the side wall of the feeding pipe 22; the sleeve 21 is disposed above the inner tank 12, and the sleeve 21 is inclined and faces the inner tank 12. Specifically, after the extracted plant fragments are discharged from the inner tank 12, the pressure plate 13 moves down, and the electric push rod 23 pushes the feeding pipe 22 to extend between the cover plate 14 and the inner tank 12 (as shown in the attached figure). Figure 4 (As shown), then the mixture of plant fragments and extract is fed into the inner tank 12 through the feed pipe 22. After feeding is completed, the electric push rod 23 pushes the feed pipe 22 out and the cover plate 14 moves down.
[0029] In summary, the plant extract extraction device of this embodiment uses the second drive device 40 to lift the cover plate 14, exposing the upper end of the inner tank 12. Then, the mixture of processed plant fragments and extract is fed into the inner tank 12 via the feeding device 20, and the extract is pumped into the inner tank 12 through the inlet pipe 18. The inner tank 12 is then sealed with the cover plate 14. The first drive device 30 drives the pressure plate 13 to slowly move up and down within the inner tank 12. As the pressure plate 13 moves downward, it squeezes the extract in the lower part of the inner tank 12, causing it to pass through the filter holes 110 on the pressure plate 13 under pressure and rise above the pressure plate 13, impacting the plant fragments above it, thus achieving the desired effect. The stirring action of the plant fragments and the extract, along with the upward movement of the pressure plate 13, allows the plant fragments to be squeezed by the pressure plate 13 and the cover plate 14, squeezing out the extract from the plant fragments and also squeezing out the original plant liquid. Through the repeated up-and-down movement of the pressure plate 13, the original plant liquid in the plant fragments can be fully squeezed into the extract. Finally, the plant fragments are squeezed by the pressure plate 13 and the cover plate 14, and the extract is discharged through the drain pipe 19 during the squeezing process. The extract can then be separated and purified. This method can extract the original plant liquid very efficiently and fully without the need for a stirring device, and it can also reduce the use of a squeezing and filtering device, thereby improving production efficiency and reducing production costs to a certain extent.
